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.
Sent from my PC36100 using XDA App
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?

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.

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.
Sent from my PC36100 using Tapatalk
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.

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.
Hey,
I'm one of the proud nexus s users since a few days. I do have a question. I've got a stock nexus s with 2.3.3 unrooted. When I charge my battery, the phone won't charge more then 96%. I have treid to reboot and charge again, but no succes. Someone has te same or knows a sollution???

As mentioned many times before in this forum, batteries are not meant to be fully charged at all. This is to extend the lifespan of the battery. High voltage (100%) stresses out the battery, so by letting the charge stop at 96% for example, it makes it as full as possible without bringing its voltage to the max. So your battery can last longer and will not need a replacement so fast. Hope this helps.
It's not a problem, its a feature. Ironically, it keeps your battery life longer in the short run and long run.

if you REALLY want your battery to reach 100% this is what you do. let the phone charge until it stops charging, unplug it from the charger, plug it back in, then continue charging it with the screen on. do not let the screen go off or it will stop charging. this method work, it just takes a lonooong time to reach 100%

That method is called Bump charge. It's useful to bringing your battery to 100%
But do not do it often because it reduces your battery's lifespan.
I will give it a try. Thanks anyway.

Umm your explanation is why people would see the phone as fully charged at 100% then unplug to find it at a lower percentage. That was because the battery had been fully charged but then stopped charging and had not hit it's bump level. Now however the issue is that some phones seem to just stop charging. Not sure where you got the idea that its bad for them to be fully charged but just think about that statement for a second.
Its bad for them to be OVER CHARGED. Fully charged (4191mV) is great but charging past that point may lead to battery over heating and catching fire as was demonstrated with the trickle charge kernels over on the evo 4g forums. This issue, the one being discussed in the thread is NOT just something people should accept. This is a bug that should be reported to Google.

Fully charged (4191mV) is great but charging past that point may lead to battery over heating and catching fire as was demonstrated with the trickle charge kernels over on the evo 4g forums. This issue, the one being discussed in the thread is NOT just something people should accept. This is a bug that should be reported to Google.

Though it might mention about the problem about "Showing 100% and instant drop after unplug from charger", but I reckon that Google is making Nexus S showing the true accurate charge.

You reckon incorrectly.
This is why many new phones will “lose” up to 10% within a few minutes of coming off the charger. The reality is that the battery was only at 100% capacity for a brief moment, after which the battery management system allowed it to slowly dip down to around 90%. Leaving the phone plugged in overnight does not make a difference: the phone only uses the wall current to maintain a partial charge state.

I have battery graphs which show the phone is never reaching 100%, or was never reaching 100% (ironically, my phone actually was at 100% for the first time since 2.3.3 this morning). As I said, this is a bug not a feature. Phones should hit 100% then drop to a "bump level" (HTC seems to like 90% whereas I believe Samsung uses 95%) and then charge back up to 100%, as simms said, very slowly. It does this so as to not over-charge the battery because that can lead to severe over-heating issues and can possibly hinder the overall life of the battery. RogerPodacter was able to modify the battery drivers for the N1 so as to prevent this from happening (not quite sure what he modified) but because of the way that Samsung set up the NS battery drivers, this is not possible for us. Again, this is a BUG that should be reported to Google.
Yeah, i might reckon incorrectly. Doing the bump charge now, it seemed to be really slow at charging from 98% onwards though.

LOL The battery not being able to achieve full charge is definitely a feature, ya sure. Absolutely. I can only use 95% of my cars petrol. That's a feature too. Definitely. My paycheck is only ever 95% of what I earned. Its a feature! People think about what you're saying >< a phone not being able to reach its maximum charge is a BUG.

Ehm... Are you stupid or something? What is those things got to dot with the battery CHARGING???
The only real solution is to get a spare OEM battery or two and a wall charger to charge them in. The batteries last 2 to 4 more hours because when I plug one in its fully charged to 100%. Plus I rarely ever have to hook my phone up to a charger anymore. Swapping batteries is so much more convenient.
And I agree this 'feature' to save my $7 battery is not a feature at all. You can find extra batteries and chargers on ebay very easily.
I agree with the above post 100%. Since I got a second (genuine) battery and an external charger, both of my batteries charge to 100% and appear to last longer. Since I started charging them in the external charger, they also now charge to 100% in the phone too. As I said in the other thread similar to this, I'm presuming the battery needed a full cycle and the charging circuitry in the phone just wasn't up to the job.

I've looked to make the same driver changes to the nexus s as I did to the nexus one, but the battery chip model and driver is different so the same changes don't make sense.
I've gone on record saying that this issue with the nexus s not charging to 100% is NOT intentional, its a bug inherent with type of driver used in the nexus s. I just don't own this phone to edit the driver and test.
But there is a line of code which I feel if it was removed, this issue may disappear. I know not everyone agrees. But my nexus one will stay at 100% for an hour and a half, every morning. And my nexus reaches 100% every single day, I've never seen otherwise. So its not the way batteries are supposed to work. If it was, they would just make the top end lower and the 96% mark would be the 100% mark. Just my opinion.

I just got the HTC One and the phone itself is great. That being said, I have one pretty large complaint...I've never had a phone that charges slower than this in my life. Is anyone else experiencing brutally slow charging speeds? Probably take 5 minutes for it to charge 1% which means it would take over 8 hours to get to 100%. Is this really possible?

I understand the battery needs to be trained but I've purchased hundreds of mobile devices in my life. Never has even an initial charge taken anywhere close to this long.
Is this using the supplied charger? Any processes running in the background that could be keeping the phone awake using power?

I know it helped with the old nickel cadmium batteries, but I've been under the impression that conditioning doesn't do anything with today's lithium ion batteries, that they are as good as they will get right out of the box.
Charge time Is a lot less than 8 hours normally. That said, it is still a slow charging phone compared to my previous few phones. However it is not too bad to be a complaint from me. We also have to be aware that the battery is a little bigger than the previous generation of phones, so it would take longer to charge anyway.

Yes this is using the supplied charger. Did a little searching online and it seems that there are others who have this issue. It was noted in the Anantech review as well as the following quote from the Droid Life review:
On a related note, the One takes forever to fully charge. I’m not sure why that is, but no matter what charger I seemed to grab when needing some juice, I found myself checking the status of the battery meter far more often than on other phones in my possession.

My phone needs about 4h to completely charge.
From Anandtech, the rationale is that Qualcomms fast charging is disabled in an effort to preserve the integrity of the battery's longevity; since you know, its sealed and has a repairability rating of 0. The Gs4 will probably crank that fast charge up and the user can replace the batteries as often as he deems necessary.
slow charging time seems a pretty fair trade off for a slow discharging time also right?

Probably this. In the end it is for the users benefit.
I was thinking, even my note 2 don't take more than 3 hours to charge. Heck even my 6200 hyperion battery takes about 5.

You shouldn't fully discharge. And my battery with the HTC charger does not that much longer than other smartphones but agree the S3 is a little quicker to charge.

From the Anandtech review:
What’s interesting however is that the charge curve gets the One to 85–90 percent under the normal 3 or so hours, it’s that last ten percent that takes forever

Maybe they designed it so that the user would be discouraged to fully charge the phone, and thus completing fewer cycles?
If it's just the last ten percent that takes such a long time, I'm not too worried about it. There are few situations during the day that I'd have to charge the phone to 100%, other than an overnight charge.

It's a pretty big batter, to start. But you're probably not getting much current to the phone. If you charge from the USB on a computer, you're hardly getting any current to the phone so it's going to charge very slowly.
The faster chargers are 2A chargers. I have a 2A car charger that came with my Nexus One car dock I've been using for a long time and it's the fastest charger I've seen out of all of them. All of my phones (and friends' phones) have charged must faster with that charger.
I have a 1.5A AC charger too. It's still not as fast as my 2A car charger, but I'm also inside at that point, so it doesn't matter. But most chargers I've seen are 1A or less. Those are slow.

It's not the battery you're conditioning. It's the battery stats on the phone. The phone needs to "get to know" the battery to accurately describe its status.
Charge time should be a tad under 4 hours on AC, so I would say something appears to be wrong. Unless of course you're doing something heavy on battery) gaming/navigation) during charging.
what scm_crash said. pick up a 2A charger if you really need juice fast, otherwise it's probably designed to simply charge overnight for longevity
I always use my nexus 7 charger (2A) when i need juice on the spot.
It's ridiculous that people here think that the HTC one is not reparable ,so HTC designed a phone that can't be open ? What if you break your screen ? So instead of repairing your screen and be charged 180 $€£ for example ,HTC will charge you 599 for a new phone cause the phone is unreparable? That's ridiculous.HTC made the phone,HTC knows how to open the phone ,HTC will put phone back together again period.

actually it's not comparable coz the volume of the battery aren't the same.
you can also check the charger's specs , a 2300mha battery charged by a 1A charger, that's approximately 2.7 hrs.
still, for the first time it took more than half an hour to charge from 99% to 100% and the LED to turn green, that was strange. probably because I deleted the battery stat file for calibration
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.

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).

A partial discharge reduces stress and prolongs battery life. Elevated temperature and high currents also affect cycle life.

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:

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.

so after reading all the post i am more confused now then i when i started. thanks guys. grrrrr.
Hello,
I am doing an experiment since few days ago. I noticed that if you disable the Fast Charging, and (most importantly) use a proper, thick 2A USB cable (I use a Kindle Fire original cable) then the battery lasts around 15-20% longer.
How to recognize that you got a proper USB charging cable ? With fast charging disabled and the battery empty, the phone should tell you that there are around 2 hours until full (instead of the usual 7 hours or so with fast charging disabled). That's when you know that you are using the proper cable. I bought a original Kindle Fire cable from Amazon and that is very solid, much thicker than the standard cable. See attached screenshot. With the standard cable this seems to be a hit and miss, you sometimes get the 2 hours message and sometimes the 7 hours message.
I repeated the experiment 3 times and each time I got significantly better battery life than before.
You may want to try it to see if it works for you.
PS: Attached is my latest battery life screenshot (APC8 firmware), which is the third charge since the experiment. 2 days 6 hours of stand-by with 5h SOT on a mix of 80% Wi-Fi, 20% 4G with nothing disabled (even Bluetooth is permanently connected to the LG smartwatch). Almost no videos played, only web page browsing which is quite demanding on battery.
Look if new software update is possible.
Yeah, I noticed that my battery life was worse when I used a ****ty 1 Ah Sony charger when I displaced the original Samsung charger. It took about 3 hours to charge it up to 100%, but then I noticed that the battery life would be worse than before. I found the original charger again, and battery life is back to being good again. I never use fast charging, unless it's in the middle of the day and I'm heading out or something.
None of the things mentioned above should (technically) have any impact on battery life once unplugged? I mean, stored electricity is stored electricity, so if someone QUALIFIED could give an explanation here, it would be cool.
Nothing new, I've always noticed that if I charge the phone with the original charger and fast charging disabled it will last much longer.

This cable? Which AC adapter do you use?
None of this solutions should impact battery life Oo. Energy is energy, no matter where it comes from?!
Would be nice, if someone qualified could tell us more..
Do you have the newest android version installed?
By the way, I only charge with original charger and cable, fast charge disabled (battery life is longer?!)
Battery life depends on how well you follow charging & discharging cycle. I usually fully discharge my battery (so that phone will shut down by itself after dropping below 1% charging), then charge it fully keeping it switched off & then use it.
I always had far better battery life than most people complain about.
BTW, I also tried charging battery keeping phone switched on at 10-15% charge remaining, battery definitely performed weaker for my use.
So that confirmed my theory based on my usage over last 7 years..

Yes, this is the exact cable I am using. A bit expensive, but for me it was the only cable that consistently worked at 2A over time.

I wonder if Qnovo is qualified enough ? Their technology is employed in many charging solutions. Here is what they say:
"Add fast charging - it gets noticeably worse. It turns out that the simple way batteries are charged today causes most of the damage that leads to shorter daily battery life and reduced lifespan."

So you're saying that Kindle Fire cable extends battery life? Isn't 100% battery life from one cable the same as 100% battery life from another cable? Energy is energy.

In no way I am saying this. I am just saying that you need a cable that reliably supports 2A charging, so the charger shows 2 hours to full instead of 7 hours to full, even with fast charging off.

Ah okay. I went ahead and bought one!
It ' also the logical thing. With fast charging , the battery holds less charge than the "normal . " He just spoke in various forums of this.
Anyway , great idea.
How to maintain max battery life span (reliable source):
Perform shallow discharges. Instead of discharging to 0% all the time, lithium-ion batteries do best when you discharge them for a little bit, then charge them for a little bit. The table below, from Battery University, shows that discharges to 50% are better for your battery's long-term life than, say, small discharges to 90% or large discharges to 0% (since the 50% discharges provide the best number of cycles-to-usage ratio).
·Don't leave it fully charged. Similarly, lithium-ion batteries don't need to be charged all the way to 100%. In fact, they'd prefer not to be—so the 40%-80% rule you heard is a good guideline. When possible, keep it in that range to prolong its life as long as you can. And, if you do charge it to 100%, don't leave it plugged in. This is something most of us do, but it's another thing that will degrade your battery's health. If you need to charge it overnight, use something like the Belkin Conserve Socket to stop it from charging after it's full.
·Fully discharge it once a month. This may seem contradictory, but hear us out. While lithium-ion batteries shouldn't be discharged regularly, most modern batteries are what's known as "smart batteries", which means that they can tell you how long you have until your battery dies (e.g. "2 hours, 15 minutes remaining"). This feature can get miscalibrated after a lot of shallow discharges. So, manufacturers recommend fully discharging your battery once a month to make sure this stays accurate.

But you stated that it increases battery life.

What he's saying is that a slower charge equals a longer lasting battery between charges.
But maybe that doesn't apply to Li-ion batteries, according to this link here.

You can try it for yourself (if you have an S7/Edge) and report the results here. I posted my results, I'm not an expert, I just tried this. I also tried the 7-hour slow charge (with a different charger) and it didn't work as well as the 2-hour charge. The 2 hour charge seems to work best.
Yeah, If you use fast charging the battery dies a little bit quicker. I recommend fast charging if you are in hurry.
I only use fast charge when I'm in hurry.. Nice feature! I try to charge my phone between 25-80%...

Worst thing you can do for the lifespan of an Li battery.

I disagree, even though it switches off itself, it still has charge, don't go by it says 1%.. so it's not fully discharged... besides my method served a good battery life to me over the years with earlier phone models
