Ok, so my battery can go from 100% full charge (overnight) to like 96% within first couple of minutes. I've done the plug/pull trick and it seems to help for a very short while and it will go back to same issue again and again.
Recently, I just bought the $10 2 batteries with external charger pack and had the extra el cheapo battery all charged up using the external charger. To my surprise, I found that the battery charged with external charger drain very accurately.
I've done some testing for a couple of days now by basically draining out the battery and replace it with a fresh one from the external charger without using the wall adapter.
So my thinking is when charging with wall charger, I think the phone does not evenly charges the battery cells because there are so many moving parts while the phone is on and charging. Therefore, it causes the cell to be charged unevenly that leads to quick battery drain.
With the external charged battery, I went from 100% to 90% in 6 hours time with light usage and GPS on.
Give it a try to see if you get different experience with your battery.
I have been doing the same these past couple of weeks (ever since I rooted my 2.2).
My external charger will be here today (it's now saturday morning cst) and I ordered it yesterday. Gotta love amazon one day shipping.
So far I have observed some very interesting charging habits the evo displays when charging with it's included wall charger and stock and extended batteries.
i went 3 days 12 hours and 46 minutes on a single charge, that is with using the stock battery and a regular wall charger, yes i'm rooted and i used setcpu to set my frequency to 614 when screen on, and 245 when screen off, at night when i go to sleep i put the phone into airplane mode, and overall usage was cut back to light to moderate usage, i was trying to see how long i could actually go on the stock battery, and i must admit i'm very impressed.

I think the general concensus was that the phone doesn't trickle charge. It will hit full then stop charging to a point then will charge again, all while saying 100%
I charged to full then while plugged in it range gps and iheartradio for 20 minutes, unplugged and it dropped to 92 within 5 minutes
Same here. I'll unplug it, browse the web while eating breakfast (about 10/15 minutes) and today I dropped to 89%. But its been two hours since then with some light texting and more browsing im now at 80%.

granted be the trickle charge is with using the stock usb connecter style wall charger right, i never use that thing unless im connected to the pc, i have a actual regular wall charger that came on another phone i used to have before my Evo, lol.
Update: Yep this morning I replaced my battery that was charged by the external charger that I bought with the bundle and same result. On average, my battery drains at the rate of 1.5% per every hour on light usage with GPS on.
I think from now on, I won't charge the phone using the default charger overnight.

So you take your battery out at night and charge it with an external charger?
Leaving the battery charging all night is bad for the batteries lifespan, that is why htc and many laptop companies implement this feature.
Stop complaining about it. Its only one cell and it has nothing to do with evenly charging, its regulated by the onboard charging system.

No I have 2 batteries, and I used one of them throughout the day including leaving it overnight uncharged, then in morning I swap it out with the one that was fully charged from external charger.

LOL, I found this statement is bogus because if you don't leave it charged up overnight then what do you do to recharge it? Come on man! Batteries are meant to be charged up over a period of time.
I'm not saying my understanding of uneven charge distribution is rock solid, but at least I backed it up with some of my own studies.
I just always do my overnight charge with the phone OFF.
Sometimes in the morning I'll also do the unplug, re-plug, wait for green trick.
As long as I don't use 4G, my battery life is GREAT.
My 4g consumption is probably worse because I've tweaked the settings to retry more often - default was 5 minutes between retries.
I guess for people that get calls late at night or don't have a home land-line, turning it off at night is not feasable. But it does get around that immediate drop problem.
They charge at a near constant rate until they are full, after that it is BAD to continue topping them off, please do some research on lithium charging techniques as your "testing" clearly hasn't taught you much if anything about the chemistry.

Lol you clearly have no idea what you are talking about. The phone doesn't charge at a constant rate until it's full. It would be disastrous for LiCo chemistry if it maintained 0.66C up until it hit 100%. The cell would cook itself to death.
The correct charging profile for the Evo is that it charges constant rate till it hits like 70%, then it slows down until it finally hits 100% and then the charging cuts off. Download JuicePlotter and completely discharge and charge your phone to see this.
Hypothesis below:
The problem with the Evo is that once it hits that cut-off point, the phone never again seems to check if the battery is actually full. (LiCo chemistry has a slight tendency to settle a few hundredths of a volt after charging, and a few hundreths means a couple of %age points when you're in the 4.1V+ range) whereas most cheap chargers will actually keep checking the voltage and trickle charging if necessary.
Too much hassle to keep changing batteries in the Evo, would have to take my case off then the back cover is kinda a ***** and feels like its going to break a tab off or something. The immediate drop doesn't bother me too much. I just use my car charger and it tops me off usually.

Yes, you are right about switching at 70%. Didn't want to complicate things since we got some novices here clearly.
The hypothesis, not so much...as I said before its intentional and it does what it does to preserve the lifespan of the battery. If you paid $10 for a chinese battery, who cares about lifespan, just use an external charger.
Charge it when its off and it gets and stays at 100. Direct evidence that what they did was a feature and not a mistake.

I been using the 700 mah charger and I've haven't noticed any difference in performance. Also again I lost 9% carge in the 10 minutes I was surfing while eating breakfast. Oh well. Im not leaving my computer on all night sucking 400 watts or more to charge a 5 watt phone lol. Ill deal with the 10% drain.
Those are the critters under your bed, they use your phone while u r asleep.

I build and design Lithium battery based systems for a living. There's absolutely no reason not to top off the battery. The recommended way to charge any Lithium cell is to constant-current charge and then constant-voltage charge up to 4.2V. Once you get to 4.2V, there's nothing wrong with charging it back up if it settles a little. In fact, most chargers don't even "terminate", they just hold 4.2V.
As for your assertion that it is not a bug, did you consider that perhaps the kernel designers are not realizing that there is some kind of parasitic drain on the battery once the kernel thinks it is full?

Just out of curiosity what kinda systems do you build? I have a lithium powered moped (lifepo4 48v 40ah) but i wouldn't say i particularly designed or built (just assembled) the battery system, would be good to have some connections with some real battery specialists for later projects.
In any case, the parasitic drain is an interesting idea but its odd that I can go to sleep, and in the morning my unplugged evo hasn't changed even 1% battery life, whereas it drains from 100% to some odd 90+ number happens when its plugged in. So the parasitic drain would have to only happen when its plugged in for whatever reason.
Some interesting stuff from the wiki.
Charging procedure
Stage 1: Apply charging current limit until the voltage limit per cell is reached.[42]
Stage 2: Apply maximum voltage per cell limit until the current declines below 3% of rated charge current.[42][unreliable source?]
Stage 3: Periodically apply a top-off charge about once per 500 hours.[42][unreliable source?]
The charge time is about three to five hours, depending on the charger used. Generally, cell phone batteries can be charged at 1C and laptop-types at 0.8C, where C is the current that would discharge the battery in one hour. Charging is usually stopped when the current goes below 0.03C but it can be left indefinitely depending on desired charging time. Some fast chargers skip stage 2 and claim the battery is ready at 70% charge.[42][unreliable source?] Laptop battery chargers sometimes gamble, and try to charge up to 4.35 V then disconnects the battery. This helps to compensate for the battery's internal resistance and charges up to 100% in short time.
Top-off charging is recommended when voltage goes below 4.05 V/cell.[42][unreliable source?]
Lithium-ion[which?] cells are charged with 4.2 ± 0.05 V/cell, except for military long-life cells where 3.92 V is used for extending battery life. Most protection circuits cut off if either 4.3 V or 90 °C is reached. If the voltage drops below 2.50 V per cell, the battery protection circuit may also render it unchargeable with regular charging equipment. Most battery protection circuits stop at 2.7–3.0 V per cell.[42][unreliable source?]
For safety reasons it is recommended the battery be kept at the manufacturer's stated voltage and current ratings during both charge and discharge cycles.

I'd have to check, but i am nearly certain this is exactly the kind of threshold charging system that you can use with lenovo's battery maximiser. As the wiki sorta explains, topping it off is fine...If you do it very infrequently (500hrs). Continuous charging from all i've ever learned on any chemistry just continues to corrode the plates until they become worse and worse at holding a charge.
No product manual anywhere will ever tell you to leave your charger plugged in for extended periods of time (save for 8hr battery conditioning on ni-cd, also of which it tells you not to do frequently). Storage instructions for lithium example say to leave the battery at about 70% charge. Extrapolating from that we can see that the lesser of the ideals is being completely empty, or too full.
Just my thoughts, much like everyone else i don't have any actual evidence that this was HTC's intention, just seems weird that they would screw something up that's been pretty much the same on the last 20 phones they made. My guess is they didn't.
Edit: oh, and the reason i bolded the military voltage is because that's another (very similar) idea as to what HTC might have done, which is lower the "full charge" threshold for as i suggested before....longer lifespan. But whether the phone ever actually gets to 100% is kinda irrelevant. My point is that its PROBABLY done intentionally to preserve the lifespan of the battery.

Plain and simple: When the Evo is fully charged, it begins running off its battery until you plug it back in. It DOES NOT trickle charge whatsoever after it reaches 100%. When you're using your Evo on the charger, and it's showing full 100% charge, it is running off the battery, not the AC plug. And then when you unplug it, well, we all know what happens next. The battery meter drops insanely fast to the actual charge of the battery, which could be very low, depending on how long it's been sitting idle at 100% on your charger.
So all those times you've charged your Evo overnight, only to take it to work the next day and be at 80% within an hour? Your Evo was running off its battery for what I'm guessing was most of the night. It takes my Evo about an hour to two hours to fully charge back to 100%. Let's say you put your Evo on the charger at 11PM, it'll reach full charge by 1AM at the latest, and then run off its battery until whenever you take it off the charger in the morning.
Workarounds?
1) Turn your Evo off while it's charging.
2) If you must leave it on for an alarm clock, put it in airplane mode and end all CPU intensive tasks to minimize battery drain.
3) When you wake up, unplug it for 10-20 minutes (still experimenting with this number), and then plug it back in to top it off. Once it reaches 100%, take it off the charger, and go about your day.
Try it out for yourself. When your Evo is 100% charged, take it off the charger immediately, and I highly doubt you will lose the 10%-15% within minutes. Please share your findings.
Er... Point of note, mine does it even if I pull it off the charger right when it turns green.
Post some technical schematic or other type of proof that shows that this circuitry isn't available in the EVO. That will prove beyond a doubt if what your saying is true.
That being said, only a group of the most retarded electrical engineers would design a charging system as you've described. It is INSANELY easy to build Li-Polymer charging circuitry that does the following (and it pretty much has to do these):
1. Detects battery temperature, and disables charging as a protective measure. In an emergency case it should shut off the device it's powering to allow the battery to cool down. This is a design requirement, or else your house burns down as you dump water on a Lithium fire thinking it's going to put it out. If you have a HERO, you can easily test this. Running the wireless tethering, GPS/Navigation, and Music with the screen running heats up the phone a ton. You'll notice the status light blink green once, then red a couple of times. This means that it's plugged in but not charging. Cool the phone down and it turns solid red again (charging).
2. Disable charging cycle when battery reaches a certain voltage. VERY SIMPLE voltage detection circuitry! The designer can of course adjust a gap to have charging turn back on when it dips below a certain voltage. Usually since this circuitry can be made with a decent amount of precision, that "turn back on" voltage ends up being roughly when the battery discharges to maybe 99.5%. That's just a guess, I admit but there's no harm in having the circuit switch on and off, even if it's often.
There are also a few other circuits that prevent the cell from blowing up in your pocket, like a current sensor to prevent an overcurrent. There's also some stuff that prevents you from being able to discharge the cell below it's avalanche voltage. In case you don't know what that is, when a Li-Ion battery discharges to a certain voltage, it avalanches to 0 (quickly falls). If it hits that point, you've pretty much ruined the battery and it will never charge the same again.
Anyway, this is stuff they taught and had design labs on back in college. While I have no actual proof that the phone wasn't designed as the OP describes, I find it highly unlikely. If this is the behavior that the circuitry exhibits, I would find it easier to believe that it's a design flaw, probably because some idiot didn't compile the correct bill of materials.
I haven't got any schematics or any sort of technical information on the subject. All I know is, it works wonders for me. When I take my Evo off the charger in the morning, it literally drops to ~90% within minutes. Once it does that, if I place it back on the charger for ~20 minutes, it charges back to 100% and stays there for 45 minutes to an hour.
I'd urge anybody who is noticing the immediate 10% to 15% drop in battery to give this a shot.
I would turn it off while I'm charging it overnight, but I use it as my alarm clock
Me Too
I am seeing the exact same behavior as the OP. This is really lame. Because of this, most people will end up losing 10% of their battery every day. Pretty lame.
I charge my phone overnight every night. Never noticed a problem and I just checked my battery and its at 88% and has been off the charger for 2.5hours so I'm not seeing the rapid discharge issue some people are seeing.
I don't think so man, I leave my screen on full brightness while it's charging, and if what you said was true it would go dead on the charger.
I think it's more likely the cells haven’t charged equally, so you get a big initial drop.

I'm beginning to think that once the battery reaches 100% full, it runs off the battery until it reaches some arbitrary percentage. At which point it starts charging until it reaches 100% again, and then continues this cycle.
I'm testing a few other things right now. Part of me is convinced it reports 100% charge when it's actually below that level.

This is what should be happening I believe, but I'd be surprised if it was set to such a huge swing like 10-15%

This is an interesting theory. I do know that when you have multiple Li-Ion cells in a battery pack, if they discharge unevenly, you have to go off of the lowest charged cell. Again, if a cell were to drop below the avalanche voltage, you'd ruin the pack all together. On the other hand, the circuitry should let ALL cells charge to 100% so it's even again. Maybe they screwed this up, that design isn't so easy! Perhaps it detects one cell as 100% and shuts off the charge. Therefore, one could surmise that if you started with an unevenly charged battery pack, you'd have an immediate decrease in charge to the rating of the lowest charged cell. The good news (maybe) is that this is sometimes implemented with software. That means that HTC could release a bug fix for this, or if we have a savvy dev, they could try to fix it. We just need to prove the theory though.
This is all just a guess, keep that in mind. If I notice something like this with my phone today, maybe I can tear apart the battery and measure the voltage on each cell (if it even has multiple cells). I have a spare, so maybe I'd be up for this. Krynj (or anyone), if you have the HTC Hero, try charging your battery pack with it, see if it exhibits the same behavior on the Hero itself. If it doesn't, then try putting it back into the EVO and see if after a night of charging, it still drops 10-15% after disconnecting it from the AC.
The reason why the battery dies so fast has something to do with the memory card. Charge your phone and take the SD card out and watch it stay at 100% for a long as time. Then do it again with the SD card in and watch it dip down fast.
Apple laptops don't charge unless battery is below 90%. If you plug in the AC and the battery is above 90%, it will just run off AC power but I don't think the battery drains any then.
My battery life has been less than stellar, but I didn't notice it dropping 10-15% instantly off the charger. I did notice that it'd drop about 10% after driving to work with xiialive streaming, which was unusual to me. The battery would start running out after about 9 hours at work. I'd be in the yellow by the time I got home, and the battery would be complaining for a charge in the evening. So that's roughly 12 hours I would be getting out of the phone after normal use.
Since I'm suspecting an issue with the charging circuitry, I just recently tried charging my battery with the Hero. After it was fully charged, I put it back into my EVO last night and haven't charged it since. It's been running 13 hours, and is still nearly full green. The charge is at about 70%. I've been trying to graph the discharge all day too. It only dropped to 87% over night, dropped to 80% when I drove to work (xiialive), and then down to 74% after I spent some time setting up icons and modifying my home screen. This is...hands down a butt ton better than the past week.
I'm not using 4G.
WiFi is off.
3G is on.
GPS is on.
Not running a live wallpaper.
Sync is running at default settings.
Widgets that could be updating constantly:
I have the Clock/Weather HTC widget running.
I have the Dictionary.com "word of the day" widget.
I have the Friendstream Widget running.
Craigslist Craignotifica app is running, set to notify me with search results.
The results are inconclusive though. Yesterday, I wiped and re-flashed DamageControl 3.2.x from scratch (backed up all apps with Ti-Backup, this means Android Market won't be notifying me if there are app updates -grumble-). So, somewhere between re-flashing and also charging my battery with the Hero caused this turn around.

Interesting.....Will have to give a try. Will report back later.
I'm waiting for some definitive results with the "use another charging device or battery" method. It seems that the EVO just sucks at recharging the battery since people who have used another phone or a separate charger seem to report better results.
I leave my phone off at night and charge it - when I turn it on in the morning it still drops 5-10% in the first 20 minutes. But during the day it drops REALLY slow, so I still can get about 13-16 hours before 15% easily.
I have manual account sync, 3g only, wifi at home, usually gps is off, auto backlight settings for screen, and I don't run too many apps in the background, I just use them when I need them.
Has anybody found a solution to this? It's really starting to bother me. I've noticed that I don't seem to have the issue if I charge -> recovery -> wipe battery stats -> reboot. That kind of leads me to believe that something is inaccurate about the battery stats and the phone instead uses the actual raw value provided by the battery instead of whatever it is that it does with the battery stats.
I can tell you this, I bought two of the cheap battery chargers off of ebay and I have two OEM evo batteries. I don't even plug my phone in anymore. I get an hour of standby at 100% from those chargers and it falls instantly when charging from the phone. I just run them down then swap them out. I couldn't be happier and they are only like 10 bucks each with 2 batteries each.

If you have apps on your sd card that are running then yes that could be the case. SD cards need power to work but I dont know how much they draw..
since owning my evo i have noticed rather peculiar battery life.
one day its ok, the next its gone 5-6 hours.
so i picked up a 3000mah battery for the wife and myself.
same thing. just horrible battey life one day, then the next.. great. i can go all day and charge when i go to bed.
yes i know the 3000mah battery is probably more like 2200-2500mah.
as i think back, and because of my job and some of the solar and battery backup systems we design for microwave radios i started to notice why, aside from heavy usage, i get poor battery life. and why under mid to heavy use i get even worse life.... i am talking 6 hours and i have just about drained a 3000mah battery.
its the HTC charger.....
no it isnt bad.. its charging the battery too quickly.
anyone who knows anything about batteries knows you can absolutely charge a battery too fast and that 9 out of 10 times a slow or trickle charge gives a much better charge on the battery thus giving prolonged use out of your phone.
not all batteries ar the same. some can handle a quick charge, others demand a slow charge.
so..i look back and i can say with total confidence that when i charge with the HTC wall charge my battery life is 1/2 or less what i get if i charge with the usb cable on a pc or with a wall charger that puts out less amps.
i also shut the phone off whenever i can to charge.
the htc charger puts out 5v 1a.
a usb port puts out 5v 500ma, (0.5a) and you can find wall adapters or car chargers that put out the same.
thus the usb port allows for a better cleaner charge.
prolonged use of the htc charger, i truly believe, will greatly shorten the life of your battery. and not just a little either.
so in the end...
1) usb a pc/laptop usb port to charge your phone whenever possible
2) only use the htc charge if you need a quick boost charge.
3) power off your phone if possible when ever using either method.

This is from a post i made earlier this morning.
i went 3 days 12 hours and 46 minutes on a single charge, that is with using the stock battery and a regular wall charger, yes i'm rooted and i used setcpu to set my frequency to 614 when screen on, and 245 when screen off, at night when i go to sleep i put the phone into airplane mode, and overall usage was cut back to light to moderate usage, i was trying to see how long i could actually go on the stock battery, and i must admit i'm very impressed.

when i charge this way i leave the phone on, instead of turning it off.
I hadn't given this as much thought as you guys but in retrospect I have to say I've had the same experience. I just never thought the usb charge would be superior to 1a charging, I just thought it was other factors like my usage or signal strength.
Thanks for this thread
Just use Baked Snack if you want battery life, or juice defender/ultimate juice.

the point of it was to see how long it would go period (as in testing), so it was used, just not as much as i normally actually do, read that post again, i think i even said that didn't i not!
Next time please take some time to read the post and think through what it says before posting!
I have had similar issues. For example today my battery has dropped thirty percent in the last hour. I think it's because of poor signal though, atleast for me. I have had my battery die in three hours before because of no signal.

Signal strength does affect battery life, I have a 700 mah charger from my curve I'll start using that to see I notice any difference in drain. Ill report back in a few days if I remember to.
My time without signal is at around 25% today. My phone has been unplugged for 3.5 hours and is at 28%.

mine was apart of the Riptide clear theme, so it came with that, however though i have seen a thread in the app and theme section with this, you might want to search in there, i know it's in the first few pages since that is a popular mod.
I just got my wall charger in the mail and am dying to use it. I've read somewhere with the batteries that the EVO uses we shouldn't drain the battery all the way, is this true? If so, that means I can just pop the battery in the charger, yeah? It'd be a pain to have to drain my battery... Thanks for clarification anyone.

this isnt about roms and apps that claim to help battery life. and just to say it, i have yet to have a rom help my battery life.
in fact... my experience is that i get the best battery life on the stock odex roms. not sure why, but i have seen it many times.
i am talking the proper way to charge your phone, and using the wall charger should only be done when you need to give the phone a very quick charge.
i charged mine the other night when it was down to 2% and it took less than an hour and a half to charge the battery, where as using the usb method, would have taken easily twice as long, and provided twice the use.
I will also say that i have owned alot of phones, and this is THE worst battery life i have ever gotten from a phone... period.
HTC isnt known for using long lasting batteries, nor creating phones that are easy on a battery. HTC makes phones with batteries that blow their wad like a teenager getting his first BJ.

You do know that the Evo can not properly charge an extended battery right? The built in power driver only charges the stock battery correctly. You can check out either of the extended battery threads in the accessories forum for more info. Though charging via usb may give you a better charge, you are still getting cheated out of battery if you charge the battery in the phone.

thats a mixed bag man, there are mixed thoughts on this, personally i follow the mfg. initial instrucitons of 8-12 hours initial charge, regardless if it says the battery is full, then i will do 3-4 complete charges and discharges.
at that point you are good to go to charge anytime you like. alot of places will tell you to not let it go below 20% and thats ok, but be sure to charge it all the way.
The more times you take it off the charger before its full, the greater chance you have of hurting the battery.
all i know is that when i charge it with the wall charger the battery drains very fast. where as with a usb port on a computer... it seems to last alot longer.
what does the evo manual say about how to charge the battery? i personally have never looked.

Well, the point I was trying to make is that roms and apps are a big part of saving battery. If you want to have a longer lasting battery you should turn off radios when not using them and undervolt as well. Baked snack is an undervolted rom with a good kernel that helps save battery and ultimate juice/juice defender turn off radios for you and have various settings for helping you get a long battery life.
I get 50 hours easily with moderate usage and right now my phone has been on the same battery percentage for 8 hours while playing music for around 1 hour, receiving a couple of texts, 10 min of phone calls, checking internet for 10 min, and having around 1-2 signal bars.
It also helps a lot when you don't use the wall charger, it just plain sucks. When I used it my charge dropped anywhere from 100% to 87-92% in 10 minutes. But with a wall charger from ebay where you put the battery in it, it stays at 100% for a couple of hours so you get an extra 10% and it lasts a lot longer as well.

i will have to research this but the batteries are the same, only one has more cells.
the only thing the phone does is read the voltage of the battery.
and they are the same whether it is a 1 cell or 3 cell battery.
one just hold more charge.
but i could definitely see where the phone might jack with the charge.
I'm curious if one could split the difference between quick charging and complete charging by charging via the wall charger up to say 80 or 90% then switching to USB for the rest of the charge?
One thing I really like about this phone is the battery life. I know this phone has a new battery technology. At work I leave it on an Android speaker dock, and at home at night when I sleep I put on charger even if battery is at 90%. I haven't been able to find a definitive answer if leaving on charger is bad for battery. Last thing I wanna do is ruin the great battery life. Should I let the battery fully discharge every now and then? Or is what I'm doing OK.

try to maintain lower charge for example a battery that is frequently at 50% or lower will last longer than a battery that is always at 80, 90 or 100%
Thanks...I'll do that from now on..I'm rarely under 50%...will make sure to do that from now on...Thank You.
My understanding is that lithium polymer batteries tend to last longer if constantly topped off, and get damaged if constantly drained and let dry. A few charge/discharge cycles from time to time help calibrate the battery.
"Continuous partial discharges create a condition called digital memory, decreasing the accuracy of the device's power gauge" Source: http://www.techrepublic.com/blog/five-apps/five-tips-for-extending-lithium-ion-battery-life/
And another way to justify topping it off constantly is the fact that we don't have removable batteries so if you are constantly on the move and out of reach of an AC outlet (or portable power pack), then you are screwed.
I usually let it on AC as much as possible (some times even during the night). Batteries don't over-charge or overheat thanks to voltage controllers in them. My old laptop still retains a charge for hours thanks to this where my friends only last for like 15 minutes. My almost 2 yr old Galaxy Note still lasts for almost a day too.

Charging your battery is a catch 22. If you discharge and charge a full 100% every time you charge, you'll end up shortening your battery's overall life, but you'll get outstanding daily use, at least for a while. On the other hand, if you don't allow enough of a difference between charges, say always charging from 80-100% instead of 40-100%, you'll lower it's daily effectiveness and see shorter daily use, but the battery will last for more cycle counts.
I conditioned the battery on my Droid RAZR to get the maximum daily use out of it. Because of that, The battery started to show it's age at about month 12. By month 18 it was performing at 20-25% effectiveness.
Having a non-removable battery makes deciding how to treat it very difficult.

You have proven my point here, you mentioned that by following your charging procedure, after just a year your battery performed at 20-25% whereas with my procedure my two year old Note still performs quite acceptably (almost a full day use). Same goes with my 5 year old Laptop.
Of curse there are other factors like average temperature you work on, usage habits, etc. but I'm just providing my 2 cents here.
Cheers!

Definitely. Having a non-removable battery with abysmal daily life, I was forced to make a decision. I crippled my use of the device in order to massage 16-20 hours a day out of it instead of the normal 4-6. At the time, I figured I would jump to a new device before I had to worry about it. I was wrong. I couldn't find anything I liked until this phone. Now, I can focus on a balance between daily max and lifetime max. But, it should take me a week or two to see how it performs for me to choose how I treat it.
:beer:
Exactly!
It's simply amazing how well the battery performs on the G2. I think that GRAM is doing wonders after all (I thought it was just a marketing scheme).

Dear god, don't listen to this advice. Rayan knows more what he's talking about.
Here is a really good article on caring for your battery.
A partial discharge reduces stress and prolongs battery life. Elevated temperature and high currents also affect cycle life.
Click to expand...
Click to collapse
Basically, the fuller you keep your battery, the better... the exact opposite of Damasterjj's suggestion lol
However, if you're storing an unused extra battery (not a concern with the G2), you want to keep it between 50% and 70% charge if you're not going to use it for awhile.
Sorry for double posting, but forgot to mention that just last night right after hitting the sack, I noticed my G2 was fully charged, so I decided to unplug it during the night just to see how much it will drain, and to my surprise, in just about 7 hours it drained only 1%! :good:
So I just concluded that thanks to the fact that the G2 charges quite quickly and it goes to deep sleep very effectively (at least mine) even though its not harmful to leave it charging, its really not necessary to do so once it's full. :good:
Fortunately I grabbed a screenshot:

Thanks WhiteZero, I totally forgot about where I learned about Lithium batteries. That's a great article.
There's just way too much dis-information on the subject.
Even my carrier's tech support staff recommends not to charge the batteries until completely discharged! They think Lithium batteries have memory effect just like NiCd batteries!

Yeah, some old habbits die hard, I guess.
Also, to maybe answer the OPs original question: I believe modern phones have charge circuits that bypass the battery once it's 100% full and still on the charger. So you don't ever have to worry about overcharge or whatever. So yes, you can leave your phone on a charger/dock for longer periods of time without issue.

Yeah, what tends to happen is when the battery gets to full, they will cut off the charge and once the battery drops down to a certain percentage will reengage. None of this is seen of course because of how the manufacturers handle the battery charge indicator. There is an almost 0% chance of overcharging because the manufacturers don't allow the battery to ever charge to a full 100%. The display, might show 100%, but the battery will only be charged to about 80%. This is usually done to extend the battery's life, to get more cycles out of it. This is based on some studies stating that charging a lithium battery to 100% full all of the time results in a shorter overall lifetime. The manufacturers don't want people complaining that they got on a 2 year contract and the battery only lasted a year.
Off topic: Speaking of the memory effect. Recent studies have shown that the batteries being used in electrical vehicles are starting to develop the memory effect. That really sucks. That means you're gonna have to run it to near empty before charging it fully. Adds another inconvenience to owning an electric car. Not trying to hijack the thread, just thought it was interesting since we thought those days were behind us when it came to batteries.
Another example that it's safe to leave devices connected to AC are shops where they have them on display. Notice they are always connected to AC (and security system).
On the electric car battery issue, is that happening on newer Lithium powered cars?

read your own article, its the same article I'm using
"A partial discharge reduces stress and prolongs battery life."
Also it says if you keep your phone at 100% you will only get 300 to 500 cycles.before you phone reduce capacity. if you keep your phone at 50% charge you will get 1200 to 1500 charge cycles.
So far I average 33hrs a charge on my phone. I frigging love this thing

I think you read that chart backwards? It says "Depth of Discharge". 100% discharge would be 0% battery. 10% discharge would be 90% battery, giving you 3,750 – 4,700 cycles.
The 1,200 – 1,500 cycles is if you discharge to 50% and then charge back to 100%. As a "charge cycle" is from whatever your low point is to 100%. So only letting your phone go to 50% is a good idea. But keeping it at 50% just seems silly.
Looking through that article's comments, theres alot of confusion about what capacity to keep your battery at. There seems to be data to say that letting the phone go to 50% then charging gives you less cycles but more overall usability.
No its not, I've done it with all my phones and never had a problem with any of them.

Is anyone else not seeing charging rapidly with their stock charger?
No, I saw rates of 1500ma with a 2.4 amp car charger, usb a to c cable (screen showed rapidly charging). I also saw rates of 2400ma with the stock charger usb c to c cable (screen showed rapidly charging). I am guessing my battery was not drained enough to see higher charge rates.
I think your phone needs to be like 50% charge or less to really see the benefits of quick charge.

It was at 15% when I tried it. I have the stock charger and the Google 2 port 22.5w charger. I was plugged into the 2 port charger, but tried the stock charger for a minute. I may have had to leave it on the stock charger longer. Otherwise non "rapid" charging still took less than 2 hours from 15% to 100%.

I tried to edit my title I know it's not quick charge, but you can see youtube reviews where their phone shows "Charing Rapidly" on the lock screen and not just "charging". The phone can take up to 15W from the Type C port.
I tried the stock charger when the phone was at 60% and it varied between 1 and 2 amps. I'm going to run another test when the battery is lower. Sucks though because I typically try not to drain it that much.
Ok, I started charging with the stock 6p charger at 26%. I'm now at 74%. This charger does not ramp up in a linear fashion like other lithium-ion chargers that I'm familiar with. It's constantly ramping up and down over and over. The highest it's achieved was 2.8 amps for a few seconds and I would guess it may be averaging maybe 1 to 1.5 amps.
I'm wondering if it's even working to spec. Seems to me it ought to slowly ramp up to 3 amps, hold it, and then slowly ramp down at about 90%.
Anyone else monitored their charge rate?
Update: It took about 90 mins to go from 26% to 93%.
That sounds faulty. I can do that with a A->C setup in an hour. The google charger should be somewhat faster (40 minutes? Based on 2A vs 3A).

Load ampere from the play store and watch the charge rate. I wonder if it's just mine that has this very strange charge curve.
Glad I'm not going crazy. Coming from a Galaxy S6, I wasn't expecting the fast charge on this to be that slow.
From 46% to full on the stock fast charger supplied with the phone, it took an 1 hour 3 mins.
From 46% to full on my Anker IQ 71AN7105 which is supposed to output at 5V, 2.3 Amps, it took 1 hour 20 mins.
Both said the phone was "charging rapidly" when I plugged it in.
Just measured on the Anker, and it's showing charging rate at 640-790ma. So you're doing a lot better than I am! No wonder it's taking an age to charge!!!!
That's like normal non-fast charge surely.
I don't trust ampere to be honest.. charging current is supposed to vary but not the amount it's showing. I wonder if it's showing charging minus load, so having the screen on will make it give incorrect results, as will the various CPU sleep states, wifi, 3G, etc.
The real world test of time from x% to 100% or how many % in 30 minutes is somewhat better in that it's measuring the end result. I'll try to do that. (/me switches rob ross on twitch to drain some battery).

A typical charging curve is shown below. The shapes of the curves might vary some by battery and circuit, but in general a battery will draw full current (up to some limit) for a period of time and then the current draw will steadily decline. This is normal. A battery will charge from 0%-30% much faster than from 70%-100%. Beyond allowing 3A to the battery, there appears to be no "fast charging" technique employed by the 6P.
The real key is what is the charger actually outputting? This should be tested by an instrument, not the phone. If, for example, the charger is outputting 2.9A and the phone is 10% charged and only drawing your 700mA there is probably an issue OR the power control is limiting current for some valid reason. Maybe the battery temperature.

I was expecting a curve like this but it was a roller coaster starting at 26%. I expect the charger is putting out because I measured a momentary blip of 2.8 amps.
As was mentioned, Ampere may be part of the problem but I don't have other tools other than a simple time to full calculation. Do we even have specs as to what's that supposed to be?
OK here are the results I got:
Both started at 10%, with identical settings (although on different days, can't help that). Normal working settings.. I avoided having the display on except for checks and it was sat still so allowed to doze.
Code:
30 Mins 60 Mins 75 Mins Total Time
USB A 47% 81% 92% 93 mins
USB C 50% 85% 95% 82 mins
And expressed as % per minute
Code:
30 Mins 60 Mins 75 Mins To full
USB A 1.23 1.13 0.73 0.40
USB C 1.35 1.16 0.66 0.71
So, C (well, google's charger and cable) is around 15% faster for me* than A.
Around 90% charging visibly slows to a crawl on both methods. The first 80% or so are fast, but interestingly C gains most at the end as it doesn't slow down as much.
Edit: If you ignore the timings at the bottom, it looks very similar to the example graph posted. Which is expected I guess.
* YMMV, standard disclaimers, etc.
one thing to note is that the phone will also charge slower if your screen is on and generating additional heat. The phone will throttle the charging rate based on the temperature of the battery.
So while it's 15% faster, the battery capacity is more than 25% larger. So how is the real gain achieved?
I'm thinking that the google charger isn't sending 3A anyway.. You'd expect more difference even if my normal charger is going as high as 2.4A (and I'm not sure it goes that high without QC). USB C might be capable of it but this phone/charger combination isn't.
Hello, guys, I need your help because I believe in the community of our forum.
I am wondering about the Dash charging.
1) Is it bad if I use the Dash all the time (every day)?
2) If I use a third party charger, in my case Anker charger (no quick charge), will this affect the system or the internals somehow?
A friend of mine is using 1+3T and he does not like to change his device often but per two years once. And that's why he is using a regular charger without any fast-charging capabilities for a mainly charging solutions. And he uses the Dash Charger really rarely (like once a week), only when he is short on time and needs battery.
I, personally, think that there is good logic in his method of charging his device, but this is only my opinion, I am not acknowledged and that's why I want your help.
What do you think about question 1) and 2) and also about my friend's method of charging.
If I think of another question I will post it later as a comment. Waiting on your replies, mates.
1. It is not. Dash charging keeps all the heat on the brick of the adapter. Your phone is safe.
2. No, it won't affect internals.
OnePlus has put the charging control electronics into the charger, keeping a lot of the heat away from the phone. But as far as my limited understanding of battery chemistry goes, it's not just the heat that ages battery cells, but the higher voltage used to charge them.
While it is impressive to see the phone charging with the Dash charger, it certainly won't help extend the life of the battery. Dash charge can push the limits of charging speed by moving heat away from the battery, preventing the phone from outright overheating, but the battery's chemistry is still put under greater strain from the higher charging current.
Even if it's only the heat that ages a battery, and the charging speed itself makes no difference at all - does the phone actually stay cooler when using Dash charge than when using a regular 5V charger?
Unfortunately OnePlus' marketing materials suggest that you should only charge your OnePlus 5 with the Dash charger, but they're just that - marketing materials. What would you have them say? "Don't use Dash charge too often since it's actually really bad for your battery" isn't exactly confidence inspiring.
The electronics for charging via regular USB, or via USB-C Power Delivery, are all there. Compared to always pushing the battery as close to its limits as possible, I cannot see the slower charging modes being worse for your battery life.
I use the Dash charger only when I have very limited time to charge my phone. When I regularly charge my phone over night, I do that as slowly as possible using a regular 5V charger. I wouldn't mind the phone taking six hours to charge overnight.
Speaking of charging, can we use quick chargers 2.0 with this phone? Does it charges quicker?
I have an Aukey quick charge 2.0.

I follow the same approach. I charge my OnePlus 5 every night with the charger of my "old" OnePlus X.
A couple of weeks ago I charged it every second or third day, and waited always till the battery is almost empty.
After I read the information provided by this XDA thread and the additional information in this article. I decided to limit the capacity and charge it every day.
So my battery is swinging about between 30% and 80%.
When on travel or time is limited I use dash charge.

This is actually awesome, being able to limit charging to an arbitrary percentage. I don't have root yet, but this one is definitely bookmarked.

As soon as the battery reaches 80% the BatteryChargeLimit Service stops charging and starts it again if the battery falls beyond 77% (The values are adjustable).
While charging (connected to charger) and waiting (connected / disconnected) till the lower threshold is reached a notification with the current voltage and battery temperature is shown.
We can cheat the electronic and move the charging logic to the charger, but we still have the physical and chemical constraints of batteries. So I thing this is a acceptable way to keep the battery as long as possible in a good condition.

That is why dash charging only matters from zero to 60%. After 60% it reduces the speed of the charge at 75% then again then again at 85% and again at 95%. It's not all about the heat but one the battery is at a certain level, you can't charge at the high speeds as that causes instability in the chemical reaction. Even QC quick charge slows down as well.

You can use any charger that supports 5v output. a qc 2.0 or 3.0 charger in this case acts like a regular charger.
the difference between quickcharge and dashcharge is that a qc increases the power through a higher voltage with lower current whereas a dc uses lower voltage with higher current.
1) Using the dash charger every time will not harm the battery or reduce its lifespan in a notable way. First of all, you only get dash charging speeds until the battery reaches 60% once there the charger reduces the output and yet again at 75% and 85% of battery capacity. This is to prevent over voltage of the battery cells which is one of the two main factors in reducing battery capacity and lifespan. The other factor that hinders battery capacity and lifespan is temperature, however, dash chargers use a nifty trick to reduce battery temperature when charging, the adapter converts the power to the battery's voltage instead of leaving the power conversion to the phone itself, this helps the phone stay cooler when charging which helps with the battery lifespan.
The one thing that you shouldn't do is keep the phone plugged in after fully charging the phone or leaving the phone charging overnight. Having the battery at 100% capacity for too long will keep it at a very high charge voltage which will reduce the amount of charge cycles of the battery. The best range to keep a Li-ion battery for a long lifespan is between 60% and 95% capacity.
2) You can use any type of charger on the 1+5 as long as it's a 5V charger. However, you won't get the charging speeds dash charger offers and since those chargers don't handle the power conversion, your phone will have to which means it might heat up a little bit more than with the dash charger.
1) ofc not.
2) no.
Will i believe the sweetest thing in this phone is about the fast charging time (Dash)
like i have my OP3 for a year now and i only use the Dash charger with it
even tho the battery still good for me
Cmon !, YES it will.
This is not a magic box people, Lithium Polymer batteries will react just like other lithium based batteries : in fonction of temperature, number of time of polarity change, load usage, and time.
This is a chemical reaction, you'll have oxydation: speed and quty in fct of previous factors. you can find a ton of info about this online, or in school.
So far a good battery that can take huge charges are Li-Fe, but the capacity is lower.
Those mobile phones batteries are good, but you will decrease their life under 20 W (5v @4A) load charge for sure !
This as been said, I know that op5 will regulate, but at the highest power that the battery can take, wich is always too high to make your phone last long with the maximum capacity you can get with a good maintenance.
I'll recommend more like 2.1, or personnaly, 1.2 A charger. Do not go lower, you'll have other issue, like crystallization.
I can explan in more scientific method, since I worked on electric race cars, but this site will explain the essentials.

Is this a big noticable difference in your everyday usage ?? No, I don't think so. You'll see the difference in 5-6 years, when the phone will be slow and the cpu will max out, and you'll do 6 hours on a 1200 mAh battery capacity since the maintenance was bad.
A couple of days ago I installed Charge Monitor (thx @waterdaan) and monitored the charging curve with different chargers on my OnePlus 5.
Here the results:
OnePlus Dash Charger, 36% - 97% in 56 minutes:

Charger from OnePlus X (standard 5V/2A USB charger), 33% - 93% in 79 minutes:
This confirms, what in this thread was already mentioned by some users. Dash Charger reduces the current at certain capacity levels.
So I think we are good to go with the dash charger and shouldn't worry that it harms our batteries.
Additionally I checked other battery apps and found Battery Warner by @P1xelfehler which can also be found on the PlayStore. This app tries to combine the capabilities of Charge Monitor and Battery Charge Limit but is less powerful as the other two.
My conclusion is: I will use the Dash Charger and Battery Charge Limit to keep the capacity between 30% and 80% for the normal daily use.
To monitor the charging process one of the above mentioned apps above is a must have. Almost all apps on the market, which promise you to extend battery life (Battery Doctors, Battery Savers, Battery Boosters, you name it...) have no effect at all and may even damage your battery.
If my assumptions are wrong, please correct me

I use the dash charger cause as for me the current looks more stable than while charging with other chargers as shown in your example.
Btw I'm using Charge monitor as well, very good app

Then, do you recommend to use a 1.2A charger through the night?
