Ok, this whole bump charging thing pisses me off. My phone should just charge, I shouldn't need to spend hours every morning bump charging it. I've read that others have found work arounds that seemed to work for them - the only thing that's fixed the rapid drain rate in the start of the day (which refers of course to the lack of a full charge) has been daily bump charging. I've read about people using Christmas light timers to do this, but this is a bit more...robust. I've tried something new that seems to be, at least for me, a permanent solution.
1. Purchase something like this. There may be other timers that would work as well.
2. Plug your HTC charger into the timer.
3. Set the timer to cut the power off at, say, 4:00AM (this was a good time for me based on when I wake up for work).
4. Set it to turn power back on one minute later, at 4:01AM.
5. Set it to turn power off again at 4:31AM (my bump charging usually takes 30 minutes per cycle)
6. Set it to turn the power back on a minute later at 4:32AM.
7. And so on and so forth for a total of about 10 cycles (this is what works best for my Dinc, at least)
8. Turn your phone off when you go to bed.
8a. If anyone can figure out a way to auto-power off at around 4:00am, this would work even better. Power Off 1.1 wouldn't work on my SkyRaider Dinc.
9. Plug your phone in.
10. If you programmed the timer correctly, your phone should be fully bump charged at least 10 cycles by the time you wake up! Power on your phone and GO!
I'm interested to find out if others have tried this method. So far it's working wonders for my battery life. Comments welcomed.
Thanks for this post, creative solutions like this one are always nice.
HTC needs to get it together and finally fix this issue. It's starting to piss me off especially in the morning when i have to turn my phone off.

Curious as to how this is an os problem when the incredible is the only one that has it. Also, i wonder how a phone that charges through an os can charge while turned off... its a physical charger problem, not os.
The OS shuts off charging too early. But, its HTC phones in general, from what I've read. Bump charging has been around longer than the Dinc.

but from googling I see majority of the problems come HTC devices, so it is prob a os to hardward issue, or a complete software issue that has been addressed towards HTC... After digging around looks like the G1 had this problem also.
So who knows.
Honestly, my goal wasn't to inspire debate. Just wanted to offer some advice that may help others. If it helps an EVO user or a G1 user, all the better.
FWIW, it is just how the phone works. My Samsung Omnia charged the same way.
I simply let it charge overnight. When I get up in the morning I check my email or whatever and then put the phone back on the charger while I get ready for work. I leave for the day with a fully-charged battery. No muss, no fuss.
What's the big deal?

I suppose I'm just neurotic in that, when I wake up to a phone I plugged in the night before, I want the damn thing to be charged. With three children running around, two in diapers, EVERYTHING is muss and fuss. That's why I posted this solution that works for me. If you don't find it necessary for your circumstances, I'm jealous.
Would clearing the battery stats after bump charging help it get a better charge even when not bump charging?

My Moto Droid didn't do this. In fact, you couldn't charge it with it off.
Nor did my Omnia.
I have an easier solution which works perfectly:
Power the phone off
Charge overnight while I sleep
Power it back on in the morning
That's it. The issue is that the phone doesn't fully charge unless it is powered off. Bumping doesn't do anything special.
Even when it is powered off, if you unplug it and plug it back in you can get around another good hour or so of charging. I turn my phone off at night but bump it when i wake up in the middle of the night because it always charges for at least another thirty minutes.

Mmmm yea I am going to have to strongly disagree...
Actually, not true (about it being the Incredible only). I have an HTC Imagio also (my previous phone) which just happens to have the same battery and it had the same issue. If I charged the phone fully, unplugged the charger, turned off the phone and plugged it back in, the orange light stayed on for quite some time before turning green again.
I'm not saying it's a totally a hardware issue (something to do with the charging circuitry) but I think it's a combination of that in conjunction with the O/S. Android defintely seems to drain the battery a heck of a lot faster than WINMO6.5 did (as proven by my friend who has an HD2 and is dual booting 6.5 and Android. He's found that WINMO 6.5 lasts at least 5 hours or more than Android).
So ultimately, I think HTC needs to look into either A) the quality of these batteries, B) their charging circuitry, C) Both, and the folks at Google need to get to work on their power management logic and algorithms.

I've seen the same results that Amin did doing this whole "Bump" thing vs. just charging with the phone off, unplugging, and plugging back in. I've seen the same results on another HTC phone as well that was a non-android phone.
If you get a set of lithium AA batteries and get a charger, you can test how this is SUPPOSED to work. If you charge the AA's fully, take them out of the charger, then put them back in, you might see the light orange for maybe a minute or so before the charger realizes that the battries are full.
The HTC phones don't seem to do this. They seem to think the batteries are partially drained.

If you charge while off and unplug and replug, you may get some more orange light time. My concern isn't whether I can make the light go orange, it's battery life. What I have observed is that if I charge to full with the phone off, I get better battery life than if I charge to full with it on. None of the other factors (unplugging, replugging, etc) seems to make much difference.
Suggested 18 hours of charging - BY AN HTC REP!!!
Ok - For your amusement, check out some these emails (link below) that people recieved from tech support staff at HTC. In one of the emails, the support rep suggested 18 hours of charging using a modified "bump-charge" technique.
Are you freaking kidding me?!?!?
http://www.incredibleforum.com/foru...scussion/1777-htc-confirms-battery-trick.html
I just bought a HTC TP2 battery charger on ebay for $5 and 2 1500mah TP2 batteries for another $5 a piece and charge one while I use the other. Almost never use the stock battery and get tons of life on the TP2 batteries. Easier than this bump stuff.
I usually just carry the fully charged stock in my pocket. Just in case I am in a low signal area all day.
Don't charge your phone overnight! When it gets really low, slap it on the charger for a couple hours until you've got 85-90%. Unplug and enjoy fantastic battery life. I have gotten about double normal battery life (approximately 48 hours) using this method. I'm on CM6.1, mind you, so it may be some quirk with the ROM.

Ive been saying this for a while. I charge up my phone to about 96% and i let it go till almost 5% before i throw it back on the charge. That usually gives me 12 to 18 hours. A lot of people tend to get "battery panic" and throw it on soon as they see it draining a bit. Just leave it alone.
I charge on a wall charger. I have three batteries and change daily. I get 22-24 hours and 5-6 hours of hard use.

Here are my observations:
The Evo seems to have a peculiar way of using external power. Once the battery reaches full-charge the external power apparently gets shut off and the phone operates on battery power until the battery level drops to somewhere around 85-90%. Then the charging current switches back on until the battery level reaches 100% again and the process repeats itself. This differs from more conventional scenarios where the phone actually runs on the external power (rather than the battery) once the battery reaches full charge.
I came to this conclusion while playing with my Evo while it was plugged into the charger. First I noticed that the charging light would cycle from green to amber and back every so often. Then I noticed that the battery level indicator would drop even while the charger was plugged in.
So I started checking my battery level in the morning before I removed the phone from the charging dock and discovered that it was rarely at 100%. I'm convinced that the phone does get charged to 100% when I put it on the charging cradle, but then it sits there running off of the battery until it drops to that magic ~85-90% level and the charging current is reestablished.
But a typical night on the charger isn't enough time for the battery level to drop enough to re-start the charging current and if I come along and just grab the phone, I'm starting my day with a battery which isn't completely charged. In my case, the only time this doesn't happen is if my day ends real late and the next morning starts real early.
Once I had a good idea of what was going on, coming up with a work-around was simple: One of the first things I do when I get up in the morning is look at the charging indicator on the phone. If it's amber I do nothing because the phone is already in charging mode. If it's green I remove the phone from the cradle for a moment and put it right back on. Most of the time the indicator will switch from green to amber when I do that, but if it doesn't I'll go online and read the news or something for a few minutes before I put the phone back on the cradle.
Either way, the phone will then charge for 30 minutes or less before the indicator goes green again. By then I'm done with my morning routine and ready to face the day, and when I grab the phone it's fully charged.
My Evo is out-of-the-box stock (for now). It's a hardware version 0003 and has firmware v. 3.29.651.5. I typically leave my Bluetooth turned on all the time, but I leave 4G, WIFI, and the GPS turned off unless I need 'em. My typical daily routine involves several phone calls, some email downloads and uploads, some incidental web browsing, and some geocaching if a new cache is published within a few miles. As long as I stick with that typical routine, my battery is always in the 40-50% range when I put the phone back into the cradle for the night. Of course if I use the phone more it discharges the battery more, but I'm set up to charge it at home, at work, and in the car.
Now despite everything I've posted here, I can't imagine any practical reason to not top off the battery whenever it's convenient. Letting the battery run down before you charge it doesn't have any effect on how long a full charge will run the phone. In fact, it will actually reduce the number of charge-discharge cycles that your battery can provide before it starts losing capacity. I don't want to type it all again, but if you're interested you can CLICK HERE if you'd like to learn more about LiPo battery characteristics and maintenance.

the evo charges to 100% then cycles to 90% then back to 100% so that it does not explode from over heating thats why when you grab your phone in the morning it might say 93% rather than 100% i dont mind though cause i dont want my phone to blow up

I'm a lot more inclined to believe that it's either an engineering error or a half-baked idea with undesirable consequences. The reason I say that is I've had countless other cell phones and consumer electronics devices which used LiPo batteries for power, yet the Evo is the first device that I'm aware of which operates like that. The rest will stop charging when the batteries are fully charged, but they'll continue to use the external power to run the device as long as it's plugged in.

I think the purpose is to prolong the battery life so it doesn't charge again every time it drops to 99%.

Apparently my point is just blowing right past everyone.
For most modern consumer electronics devices the charger can serve at least two functions which are charge the battery and run the device. These functions are remotely related by virtue of the fact that the power comes from the same source, but the functions themselves are typically quite independent of each other. In other words, most devices can run off the charger's power regardless of whether the battery is being charged or not, and when the device is running on the charger, it's not drawing power from the battery.
But it appears that the Evo doesn't do things that way. In essence, it seems like the Evo is hard-wired to the battery and the charger is incapable of independently powering the device when it's not charging the battery. So the battery reaches full charge, the charging circuit shuts off, and the phone starts draining the battery despite the fact that the charger is still connected. Once the battery drains to ~85-90% the charging circuit kicks back on, the battery gets charged back to 100%, and the whole process repeats itself.
Consequently it's a crapshoot whether our Evos will be fully-charged when we take them off of the charger unless we take some additional steps. I can deal with those extra steps, but I can't come up with any practical reason why we should have to. No matter how long I analyze the situation, I can't see any benefit to doing things that way except, perhaps, to save on manufacturing costs. All I can come up with are annoying extra steps and unnecessary battery charge-discharge cycles, and I can't grasp how those benefit anyone.
I see that you and I have carried some of the same phones in the past, TheBiles (Sanyo 8300, Treo 650, Hero) and I don't remember any of those phones coming off a charger with anything less than a full charge unless I interrupted the charge cycle. In fact, I'm convinced that no phone that I've ever carried has had this problem. The Evo is the very first one which is why I suspect some folks at HTC are quietly saying oopsie.

Pete, I'm not convinced most smart phones actually power themselves off of the wallcharger when plugged in as you seem to think. I have no real evidence to back this up, though - other than my own observations.
I will say that the EVO's method isn't as isolated as you seem to think. For example, the Palm Pre which I owned for a year previous to the EVO operates in the exact same manner.
The Pre would hit 100%, stop charging, operate on battery power until it dropped to 95%, then charge from 95 back to 100. The EVO, however, drops down to 90 before it starts the charge cycle again. This is probably better for the battery - but more confusing from a user perspective.
This might be your first phone that operates this way, but it certainly isn't unique to smartphones or HTC.

I completely agree. This is clearly going on, and I'm surprised more people don't talk about it. I put Cyanogen on mine the day I got it, so I thought that was the issue, but I went back to stock (for a day) and it did the same thing. The light goes off after 90% and it stops charging at 100% until it drops below 90%. I also agree that it doesn't seem to serve a usable purpose, and seems to be a design flaw.
I'm still very happy with the phone, but when battery life is this important, that's kind of a big deal.

I had two Pres, and both had the battery % mod on them. I used to set them on my touchstone at work all day long, and I would take them off periodically. My battery drained so bad I could lose 30% in an hour with light use. If I ever took it off the touchstone when it wasn't at 100%, it was only because it got too low and wasn't at 100% yet. I noticed this on day one with my EVO, and never noticed a single issue anything like this on my Pre.
I'm not saying it wasn't there, I'm saying I NEVER noticed this. As far as I knew, it charged to 100% and then ran off the plug, or at least that's what I assumed.

You may not have noticed it, but I can guarantee you the Pre charged as I described. It was a "crapshoot" when you pulled it off the charger as to where you actually were in the charge. You could be anywhere from 95 - 100. Of course, the Pre would always show 100%, just as the EVO does.
Because the Pre's battery was smaller, WebOS was more battery hungry than Android, and the fact that it only cycled down to 95 instead of 90 like the EVO are all reasons why you might not have noticed it, but it was there.

Why would it be better for the battery? They may be partial charge-discharge cycles but they're cycles nonetheless and the Lithium Polymer cell chemistry is only capable of so many of 'em before it starts to degrade. Short cycles are easier on it than full cycles, but they all take a toll.
I currently have something like 40 LiPo packs that range from dinky little 35mAh single-cell micro batteries to a couple of 10S (37V) 5000mAh packs. I use them in my R/C planes and helicopters, communications gear, and electronics projects and I've used up and disposed of many times that over the years. I even had to build my own packs and chargers when I first started using them because the cells were experimental and there wasn't anything commercially available yet.
And I survived all that without having a single LiPo fire (that I didn't deliberately trigger) and I attribute that to the fact that I've been rabid about learning everything I can about the technology and the use and care of the batteries.
And I'm unaware of any benefit that can be gained from unnecessarily cycling LiPo batteries regardless of how small the cycles are.

My predominant theory is that HTC has erred on the side of caution on the advice of their legal department. LiPo cells can easily become little firebombs if they're mistreated and the overwhelming majority of "events" occur during a charge cycle. Search YouTube for lipo fire and you'll find pages and pages of examples, but beware:
You may not want to carry yer phone in yer pocket right next to yer cojones anymore after you do.

Having the wall battery charger solves this issue. The wall charger will charge the battery to full capacity.
It also allows me to test battery life on roms/kernels as accurately as possible. Only time I connect the phone to USB is when I need to move files.

When you say wall charger, do you mean one that you have to remove the battery from the phone and insert it in the charger?

Just wanted to say that there have been many discussions on this here at xda, I guess most of us just deal with it.
What I do is charge externaly with a cheap Chinese charger that Came with two batteries that work great.
Every since I made this move I haven't looked back. My battery life is great now, 24 plus hrs per charge. Sometimes I go close to 40 hrs, and I use Bluetooth, have GPS and WiFi ways on. In fact I don't cut any corners, no under clocking either.

It seems common behavior on the Nexus. My NS got up to 105° F last night (to be fair, it was under my pillow). I've simply taken to turning it off when I charge at night, but seeing as my NS is a glorified PMP (and therefore I don't have to worry about texts or other notifications on it), you might feel differently about simply turning it off.
Sent from my Nexus S using XDA App
It's interesting to note that the adapter for the Nexus S actually charges at(and I'm sure I'm getting my terminology wrong, sorry electricity guys!) .7AMP vs the 1AMP that other smart phones charges at such as the Nexus One.
This might account for the seemingly longer charge times we've had reported, and why you might be seeing increased heating from using a third-party more generalized charger. Whether or not there's any truth to the idea that it may cause permanent damage to your device, I don't know. I would greatly appreciate it if someone more knowledgable about this kind of thing would post, as I'm considering buying a second charger/car charger. In any which case, I personally take what Best Buy/T-Mobile/anyone's first level support tell me with a great big grain of salt.
google maps heating phone up
I just had a similar experience with my Nexus S getting really warm while using Google Maps this morning. I usually use Google Maps in Car Mode with traffic overlayed as I drive to and from work (~30-40 min. drive). This morning I noticed the phone got really warm by the end of my commute, which did not happen the previous 3 or 4 times I have used Maps in this same fashion. I will take nxt's advice and check the temperature on the phone next time it heats up again. Does anyone know what is a "safe" upper temperature limit for the phone or battery? I've read that higher temperatures are detrimental to the life of a lithium battery.
Other than this one time, I have not experienced any other high temperature issues with my Nexus S in the ~1 week that I've had it.
Thanks ahead of time for any help/advice. This is my very first smartphone and I am eagerly trying to absorb as much information as I can about it so I can determine what is normal/abnormal behavior. I am loving my Nexus S so far!
I don't think third party chargers are to blame. In fact, I'd go as far as to say the opposite is true. I read that the shorter data pins on the official charger cause the device to enter a faster charging state, as compared to the usb cable or third party chargers.
I've yet to feel my nexus s get warm at all... during charging w/ wifi on. Using samsung wall charger, using LG wall charger, using computers w/usb cable.
My NS gets hotter to the touch than my Vibrant ever did, but when I check the battery temperature it is never as high as my Vibrant used to get.
When charging in the car and running Navigation + streaming music the Vibrant would hit almost 125F whereas my NS tops out at 110F.

Today was the first time I've felt my Nexus S get super heated when charging. Never happened before. I've been charging the same exact way since owning the phone back in December.
Odd.

it depends on the usage
when i download TONS of stuff via 3G or WiFi it heats up a lot, only if i have it plugged in to the charger, else it does not heat up
However! if you check carefully, or better yet, if you take out the back cover
you will notice it is not the battery that is hot, but the area beneath the SIM card that is hot, which points to be the CPU

I see, thanks. Will keep in mind.
FWIW, I have been charging my Nexus S with the Nexus One charger (1 amp) since day 1 - I can't stand how short the stock charging cable and wall adapter were. I haven't had any unusual temperature spikes when charging at all. I don't even really notice it getting warm under heavy load - unlike the Nexus One with the aluminum casing that conducted heat very well. Edit: I also leave WiFi on with a No Sleep policy when I am at home and I've not encountered any warming issues either.
I would be careful if I ware you.. high heat is dangerous for the battery, it might swallow and even a leak if you will keep using your device constantly at high temperatures.
I Have never had any problems with heat and I have been using it a lot.
btw, I use stock rom..
The note is a disaster for me when it comes to charging.
If your battery is low and you start charging it but using it at the same time, it doesn't get worse, but it doesn't get better either i.e. actually charge the thing, it just holds its own.
I have got to say I am not impressed with this!
I am not facing such problems. Charging takes pretty long yes but not as bad as you said. A larger battery will of course need a longer time to charge. But I wonder sometimes too if it's the battery problem or the charger output problem and if there's a way to speed up the process.

I think it is more to do with the actual charger, seems like a trickle charge or something.
Yes if charging and using at the same time you would not expect it to charge as quick, but mine doesnt really charge at all, just stays the same.
My acer iconia will charge like lightning even when i am using it, smaller battery or not it still charges!
This was one of the things i was looking forward to with the note, but this slow charge seems to make it more or less the same as what I am used to.
I have the usb plug which comes with the kindle, might it do a better job?
If anyone manages to find a proprietary charger which can produce better charging I will like to know too
That is common the charging is very slow and if you are playing HD games then the charging is almost in negative. May be its because of the voltage of the charger inputs and it is to low. Samsung must have done it for a reason may be its because of the proprietry port or the battery itself we do not know but we need to live it
Agreed, charging this thing takes a long time. Keep in mind that the battery is 7000 mAh and the charger is most likely a 2 amp charger, pegging the charge time at around 4 hours with no other losses. So if you're using it, it should take even longer.

No such issue here. I charge to full capacity while using all the time.
I get what he's saying. Because it draws so much power when you're using it; having it charging at the same time doesn't move the needle much. For example, if you're watching a movie while it's charging you'll probably be at the same point battery wise when the movies over. People complain about this all the time when their using their devices as a GPS. In some cases not only doesn't it charge but it actually continues to drain so you're worse off from where you started. We're using 21st century toys powered by 20th century battery technology.

This is a better way of saying what I mean, thank you.
I also have to say one thing I do not like doing is turning the screen brightness down. After all we all get these things as they look so good, so I am not going to make it look worse when I am using it, what would be the point in that? Its a bit like saying yeah my battery life is 14 days but actually it is on standby for that time lol...
Anyway, I still believe it should be better and the primary cause is the weak charger for what ever reason sammy decided to make it that way, but its not a good thing.
It seems like I remember someone recommending a charger that was more powerful so the note would charge faster. Can anyone confirm this?
What a fail thread. If you know ANYTHING about charging, you would know why this happens and why this is NORMAL.
But why even search or educate oneself, let's post a thread on XDA and whine a bit.
It could be worse. It takes six hours to charge a N10.
I dont face this problem i charge mine when surfing the wep
On a slightly related side note, doesn't it suck that the brightness just turns down completely when the battery is low?
The zslower charge rate protects the batteries life ,reduces the possibilty of heat and battery damage trickling insures a full charge
if you don't want your screen to dim don't use the power saving setting.

For all those facing the slight unresponsive screen please change the source of power, I had mine connected to UPS power supply as soon as I changed and connected it direclty the problem was gone.
Even if you read the user manual of Samsung Note its says thats one of the reasons
How Manhattan hours per day do you use the note? With a 10hrs battery life I find an overnight charge is sufficient

Wow! many friends?
Anyway moving on.. so i just got my note 10.1 about a week ago, loving it but saw that while plugged in it was not charging at all while i was using the tablet and never quite getting to 100% overnight. By not charging while using, i mean to say that it was actually discharging. Yes of course i am using the stock charger and cable.. and even stock note.
so just tried something silly. Unplugged and plugged the usb from the block repeatedly about 5 times. Now its not only recognizing and charging, but charging relatively quickly even while using. To test, i unplugged for about 20 min and plugged back in. Same great results.
Just thought i would share instead of hoarding my new found knowledge like others..
Quick update: it charged about 10% in 20 min.. Nice
I don't charge mine - I paid cash for it
So, like most S8 owners herein, my device use to fast charge when I first got it....or so said the description in the notification bar. Recently, in the past few weeks, I noticed that it now only said cable charging. I was pretty irritated because fast charging is really desirable. Being able to top up rather quickly removes any concerns I have about battery life on the device, though admittedly it generally lasts me 24+ hours.
Anyway, I checked around in the forums and realized that many owners had this same issue and nobody seemed to have resolved it. Yes, some said use the original charger (I did, to no avail). Others said to confirm that fast charging was on (I did that also).
Then, I remembered reading an article about how the S8 doesn't actually fast charge when the screen is on. So, I wondered if maybe that's why I only saw "cable charging"...because the screen was on to see it.
As an experiment, I installed Ampere and left it running. Of course, while the screen was on, charging only measured about 1000-1100 mA. Yup, that's slow and confirmed my worries.
But then, what I did was to turn off the screen and wait a few minutes, while leaving Ampere running in order to see the max value. Surprisingly, and refreshingly, when I unlocked the device and checked the max value observed in Ampere, the S8 had registered a value of 2520 mA!
So, I think what's happening is that Samsung eliminated the fast charge notification because people were complaining that it wasn't fast charging when the screen was on. However, when the screen is off, it actually increases the charge. Alas, without the screen on, one cannot observe a fast charging notification.
At the very least now, I feel relieved to know that fast charge appears to be working. I'd be curious to hear what the rest of you think. Cheers.
This makes sense but my S8 still charges slowly even with the screen off. I'll try your test and see what happens. If I want it to charge faster, I turn the phone off completely. This very reason is why I ditched my samsung notebook. There was a system upgrade that disabled the ability of the device to charge while on. So annoying.
As I understand, that S8 enables fast charging when screen is off. With the screen on, it is slower.

Wow that would be really annoying on a laptop. I know they're stepping up battery safety but that's a step too far!
Yes from what I've read fast charging only works with the screen off, this is to limit the phone from getting too hot while fast charging and using your phone simultaneously.
As nice as the S8 is I really think everyone should just use oneplus`s dash charge. It's so great, filling the battery in 50 minutes... Quick charge is way inferior.

I think you hit the nail on the head. It seems that Samsung remains quite stung but the blowback from the battery issues surrounding the Note last year so they are taking NO chances with the S8.
