It seems several people have charging issues with GB. If you have this issue, regardless of rom, post what you have tried to use as a workaround, successfully or not. Also, how long it took for issue to appear. Phone configuration is optional, but there may be something a dev sees as a pattern, even if we dont. I would also encourage posters to share build date of their device.
This thread its for everyone, but I would ask if you are one of the lucky ones not affected by this issue to refrain from posting "I never had a problem...". This thread will hopefully bring more light to this issue for dev's, as currently complaints are posted only in the thread for the specific rom they are using.
To all that post, thank you.
Mods, I posted in wrong forum. Please move to general.Thank you.
reserved for later.
I've seen it, if I charge my phone to long. I'd wake up to a fully charged notification unplug and be at 74% or so.
As a workaround I charge it full right before bed and unplug it at full, since it sips battery just chilling overnight I wake up to about 94% or higher. Plug it in, hop in the shower. Unplug after and I'm good for the day ;p
Ok, since I started the thread, I guess I should post my experience.
If I have just flashed s rom, the first 2 charge cycles work perfectly. After that it goes downhill. 91%, then mid 80's, anyone s guess after that. I've tried multiple combinations of flight mode, data deactivated, and cache/Dalvik wipes. Nothing. The part that confuses me is the first 2 cycles after a flash.
Now, about my phone:
C5.3 (today), Talon 0.1.5, ext4, all tweaks except governor, oc to 1200mhz,-50 uv on all states except 1200, GingerBlue theme (thanks Viv), stock modem, auto rotate/brightness off. I use the cable that came with the phone to charge with (wall charger), and my build date is 1007.
My bug is that it always fully charges to 100%, and just keeps cooking the battery. That cant be good for the batt.
On all Froyo roms / kernels, it would drop to 98% or so like it should.
On Continuum 5.3 / Talon 1.5 it just fully charges..
I use an ammeter but also have a supply that stops blinking when the phone stops charging (long after it shows the battery full notification). Unplugging at that point will show 100%. The problem is that when it reaches full it switches to battery and drains it for several hours so you might see 80% when you unplug it in the morning if it's been running on battery for a while.
The battery gauge and notification are way off. Don't trust them, but I can assure you it's not overcharging.

Guys,I own a T Mobile G1 Android 1.6 Phone and recently I’m facing some problems. The problem that appeared recently is with the battery drain. before some days ago the battery of my G1 lasted up to 4-5 days, without using Wireless, GPS, and Bluetooth. If I used the mentioned services normally the battery lasted up to two days. But recently the battery is draining too fast. Within 4 hours the battery goes down less then 15% even I do not use any mentioned services. I keep my phone on standby, without talking a single minute with the phone, not using any service etc, and again it goes down very quick. I took some measures according to HTC instructions how to save the battery but again it does not function. I uninstalled all applications and reset the phone to factory setting by again same thing. Then I searched on the Google some instructions, I tried also that one’s but again it does not function. I always used HTC charger that came with the phone but again same problem. What is the strangest thing that after some days the battery gets back and works perfectly for two weeks, which means I use the phone normally without charging 4-5 days. As I operate very well with the smartphones, Pocket PC’s etc I start analyzing G1 and monitoring very closely why the battery goes down, I monitored for a long time the query under the :About Phone-Battery use- and I see there that Andorid OS is using the battery from 76% up to 85%. Now it came to my mind that something is keeping engaged or it keeps running the Andorid OS always on. Then I suspected that thre my be any virus on my phone, but I installed form Market Flexilis/lookout antivirus application, but there was no virus and again the battery goes very quickly down. As I said after sometime the system returns to normal and the battery lasts for 4-5 days, and when I check the information under Phone,Battery use, I see that the Andorid OS is spending only 6% of the battery. Comparing with the previous description it is a huge difference. According to my opinion there is a small problem with any file which keeps always running to much the Andorid OS. Can you please give me any instruction why Andorid OS is spending that much the battery? Or give me any instruction how to prevent this operation that keeps Android OS to much engaged? or is there any programming mistake?, is there any need for update?, do I need to root my phone as it is not rooted? The reason why I’m thinking that there is a technical problem is because sometimes the system gets back to normal and sometimes it goes out of normal running. I appreciate a lot if you could help me to resolve the mentioned problem.
I've noticed the same thing on my G1 sometimes there is fast battery drain and it seems associated with Android OS. The percentage is over 70%. I also notice it be associated with the display as well. Could be that there is some process that won't stop running and is using Android OS or it could be that on other occasions the display is not going into sleep mode properly. I wish I knew how to fix these problems but I don't. I just observe them.
The battery issue, is an up and down problem for me. Sometime I can go through it in one day or less, other days it will last me for 2 plus days.
It also could be that the battery need replacing. Who's know.
I just bought a 2nd hand G1 - works just fine. I rooted and installed CM6.1.
My battery drains within 1-2 hours. I've tried various methods of resetting stats, with no luck. How frustrating! I wonder if it's a battery hardware problem or software?

I also faced bad battery life on various roms. Since I'm using COS-DS (android 2.3.3) http://forum.xda-developers.com/showthread.php?t=950765 and the Biffmod kernel http://forum.xda-developers.com/showthread.php?t=950765 the phone runs more than 24h when texting and calling. Of course you should apply the 14MB RAM hack in comination with this kernel http://forum.xda-developers.com/showthread.php?t=831139. On standby (everything off, except data and 3g) my G1 runs >48h, before it needs to be plugged in.

Sounds like the basic description of the USB Charging Bug.
The bug triggers if the G1 is using a kernel starting 2.6.35 and onward tree, and charged using the USB instead of AC wall charger.
A couple of option to avoid the super discharge after that (you can use either);
1. Reboot after you unplug the USB charger.
2. Change kernel to one from 2.6.34 tree
You can also visit the Dev sub-forum, there's a thread there discussing the debugging process.
It is so unpredictable for me...I have just got into the habit of a reboot after unplugging USB.
Battery drain on the G1
I have the same problem. Even on standby it drops to less than half of its battery life. Sometimes its worse. today i noticed that the battery percentage was at 84. Next thing I know the phone reboots itself and it displays that it has 1% battery, battery icon empty all in red and LED flashing in red. Then I turn it off connect it to the charger, after a couple of seconds I turn it back on and says its 90 something percent. Could be a virus or just a battery bug,that's my guess. I scanned the phone with Lookout Security and there was no Virus,malware or spyware found.
I want to try different kernels for this battery issue but want to make sure I am installing the right one.
I have CM6.1 with 2.22.23.02 radio and DangerSPL installed. Can I just load any of the kernels built for EBI0?
Specifically, can I flash the kernel in the 1st post here? http://forum.xda-developers.com/showthread.php?t=1010932
Thanks.
Not sure if this is a problem with the captivate (Rogers I897) or if it's just a select few, but I noticed last night despite the usb charger being plugged in overnight, once the battery reported full, it stopped charging.
So basically, I got home from work, plugged in my captivate because the battery was rather low (only takes 24 hours of maybe 30 mins to 1h of actual usage before I get below 40%), and it took 4-5 hours to charge completely. When I unplugged it in the morning though, it was already down to 64% with just being idle all night.
So is this normal or should I ask for a replacement battery or something?
There are a lot of posts around here about batterirs dying quickly, and "charge death", but I'm not really sure whats going on with your phone. All I can suggest is that you make sure that you close all apps and stuff before letting it idle, and just see how that goes. I suppose you could just have a bad battery. Are you on a custom ROM or stock? I had problems with battery life when I first flashed to a custom rom, but since then I've switched to serendipity 4.3, I have it undervolted, I keep an eye out with a task manager, and my phone has no problems lasting all day, even while texting a good amount/using it for searches and stuff.
What ROM are you running?
Did you have GPS/Bluetooth/Wireless left on?
There are known issues with certain builds of ROM's causing this issue. If your on a stock ROM and still having this issue? I would take it in to possibly have it warrantied out or at least have the battery replaced.
I haven't ever had an issue with my phone losing a charge while plugged in.
Yeah, stock ROM. I haven't installed any additional task managers, but I usually open it up and kill all tasks when I'm finished with them.
I do keep bluetooth and GPS off at all times, but I leave wifi on overnight because I didn't think the battery would stop charging entirely once it was full. I've only had the phone a week so I could get it replaced, I just wanted to investigate it a bit to see if it's a common issue or not before I did that.

Settings --> Mobile and Network --> Wifi Settings --> Advanced (soft key) --> When screen turns off
This would turn off wifi after 15 mins of inactivity. This would help save ur battery.
And yes, charge does get cut off when left for extended times, but not right after it says charge full.
Recalibrate your battery/battery stats. This is my method, there are many others though:
1. Charge the phone with the phone ON, until the phone indicates full battery
2. Unplug the charger, replug, continue charging until full battery again (I repeat this 2-3 times)
3. Turn off phone, charge until full battery
4. Unplug the charger, replug, continue charing until full battery again (Again, I repeat 2-3 times)
5. Turn on the phone, let the phone charge yet again.
6. Boot into Android Recovery, delete battery stats (Advance -> Wipe Battery Stats)

Cool, I'll try this, thanks!
By default, wifi does get turned off when the screen goes dark and I haven't changed it.
I've also been tring to flash to a new ROM (been trying Android 2.2), but Kies won't load my phone). I think I'll research other methods when I have time.

If u r not heavy on data and use it for things like mails and chats, and esp when in an area with no proper 3G coverage, u can switch to EDGE and get out of 3G. 3G sucks more battery compared to EDGE.
So I wasn't able to complete all the steps to kind of fix the battery problem, but I plugged it in to almost 100% (I think it was like 98% or something, I had to go out so I had to unplug it), but when I got back I plugged it in again and let it charge overnight. This morning however, it was still at 100%, and now, about 8.5 hours later, it's only at 73% so I think maybe it just had to normalize it.

Give it some time to normalize. And charge showing 98% when unplugged at 100% is normal.
And yes, seeing 60% battery left after an hour of calls and tasks involving an hour plus of display on after a day's work, apart from push emails, etc (~14 hours standby) isn't so new anymore to me.
Stop watching the battery so closely for about a week and u'll be all set
I was on darkys 8.1 rom with jk4 modem, calibrated the battery one time and I went 18 hours. Starting from 98%
6 hours were phone calls, 1.5 hours of text messaging. 2 hours of power amp . The rest was pretty much just standby/idle time.
Though, I don't get that anymore though.. Jk4 has gone to **** for me. I used to get full signal majority of the time, and for places where other people go no bars, I got one or two. Now its pretty horrible it makes me sad ;(

This seems to be quite a common and somewhat obscure at the same time.
Many people have reported installing a new rom or even just powering up their phone and seeing a battery % much different from what they expect. Most often much lower than it should be. Evidently this corrects itself after some time but it's a real problem if your display reads <15% because you really have to plug it in then, even with you know you have 90% battery!
So, here's the solution after testing it under different circumstances over a few days:
Simply boot your phone when it is not plugged in to a power source and battery % will be accurate.
That simple. Silly LG!
So, if you flash a new rom, unplug the USB cable before you reboot...
Hit 'Thanks' below for the 50 reboots I did to prove this...
hehehe jups allready figured that out on myself tho haha. But indeed that's kinda silly of LG

Sorry to say the same..
Even while charging with the phone shut down, pulling it off the charger and then booting this happens. On my phone I have experienced it on all MCR's.
It's really not a big deal as long as the battery performs as Stock 10b, that build has been stable batterywise on my phone. But staying stock isn't too much fun
Well, every time I charge, whether I reboot/shut down before unplugging or not, my charge always maxes out at 96%.
Annoying and I'd like it sorted if at all possible.
Anyone?..........lol

ye i got that exact same issue i was wondering why that was happening and hoped that a simple reboot would fix it but its a bit more complicated than that i suppose...
also the battery reset in cwm didnt fix the loading till 97% w/e percentage.
when i install the stock rom it allows me to load it till 100% though pretty weird stuff -.-

I had a replacement netbook battery that could only max to 90%. So, over the weekend, I practically drained it to 0% (not a healthy practice for Li-ion batteries but I was desperate). Took out the battery for a while, and then recharged for several hours. Well, it seems to get up to 100% now.
Perhaps you could try using the the phone until it very low on battery before recharging. Maybe the charging process in the phone needs some sort of recalibration. But should not be doing this all the time as it will reduce Li-ion battery longevity.
Let mine totally die last night so it wouldn't even turn on at all. Took out and replaced battery and then charged it overnight and hey-presto, when I unplugged it this morning, it stayed at 100%.
Solved indeed....for me anyway. Feel free to try the same and post your results.

I'll be sure to try your tip man. But not easy drain it completely when I always need the phone :=)
I guys! I've got the same problem.
I think that it could depend on the "full battery popup FIX" that Paul introduced in his roms by the FR8.
So I would like to ask Paul if you can create a patch to remove that fix. Just to try it!
According to me, incorrect battery amount depend on a wrong voltage read error (offset introduced?) by the rom. :blink:
In my case, I have followed many times battery wype procedure without positive issue. The matter leaves only by flashing original roms.
I think that if Paul have written a wrong battery values range (to delete the battery full popup) that can be traduced in an incorrect battery status displays.

Perhaps, but you can not conclude it was introduced by MCR. You logic is wrong there.
Even without "battery full popup fix" it doesn't work good...
Battery level, when unpluged, stay at 100% for 2 minutes afterwards drop down fast until 85% then drain normally...
I'm getting huge battery display problems no matter what I do.
When I took it off the charger this morning, it said I had 100%... thats fair enough. However it stayed at 100% all day, so to "refresh" it this evening I restarted the phone, and low and behold it now says I have 27% left. But again, it's just sticking at that value, even with me now plugging the phone into the wall to charge. It simply says "Charging (27%)" and won't budge, likely until I restart the phone again.
Sometimes it works fine, it seemed to be doing ok last night before I put it on the charger. Any tips/suggestions? Is this something likely to be fixed when the Gingerbread update rolls around?
This is my first real smartphone, and am fairly annoyed as its giving me a fair few problems that I've not had from other electronic devices.
As I stated in another thread, I had the same issue while on MoDaCo Fr12. However, after reverting back to stock, the battery percentage is spot-on and I'm getting up to 48 hours use out of it.
Draw your own conclusions.

That sounds super, but I'm still on stock too. About the only things of note I've done are root and switching to Launcher Pro. Oh, and Clockwork Mod of course. Perhaps a complete reboot is needed, we'll see how it goes.
Saying that - since charging, my phone has been at 90% all evening, until right this moment when it changed to 89%. It's less than I'd expect on this type of phone for 3-4 hours use (or lack thereof, I've barely touched it), but it's a start eh?
Welcome to the world of smartphones my friend. I've had various handsets over the last 4 years from iphone to android and a day and a half out of the battery is about average......at best. ;-)

Just to clarify, what I meant in my previous post was that I was expecting to battery to drop a lot more than it did. The fact that it only went down 1% in several hours of use prompted me to think that the battery value was messed up.
As it is, I've not charged my phone in the 36 hours since, and it tells me I have 73% battery left. Perhaps it is performing extremely well after all? If that's the case then I'm more than happy with it, but being the pessimist I'm still expecting the phone to turn off sometime with the battery reporting incorrect values.
Hey guys, have a quick question for everyone here
Ok so i finally flash Firefly 2.8 full over my previous Firefly 2.7, ramp the battery up to 100% and use the Battery Calibration app. Everything is running smooth until tonight when i'm changing rooms, I accidentally plug the phone into my computer for about a second. Quickly pull the plug but the damage is done. The battery has now been unplugged for 30s.
Granted, i forgot to do a bump charge on the phone the first time around, is there any detrimental effect of running battery calibration multiple times in a short period of time? I know the app only deletes the battery stats, I was just curious. I plan on bump charging the phone soon anyways, just wanted to know.
Check the thread on battery calibration. I think its under general, not q&a
And next time, please TRY using the search.
Sent from a place my wife doesn't know about (yet)
My apologies, when I put in the title, I didn't see that thread in the similar threads posted.
Okay, this thread is probably misleading. This could be a bug, nothing more.
When I complete a build and then push it over the USB I have noticed something funny.
If I keep the cord attached when I flash, when the nook finishes booting, my battery gets reported as 100%. I can't say for sure that it happens everytime, but nt happens pretty often, at least.
It's pretty hard to tell, but it really seems to get 100% charged. The battery doesn't seem to drain any faster.
Now, I haven't checked it with any serious discipline. Maybe the nook would just shut off at 30% or whatever. Maybe it just reads the percentage it was at previously as 100% at this instance. Maybe its hard to tell if the nook just drains 15% faster. Maybe who knows what.
But its happened several times, and it sure seems to be 100%. I've checked all the levels in Battery Monitor Widget. (Science!)
So what do you think? Did my nook develop cold fusion or did I discover a misleading bug?
You can see the voltage jump in the attached screenshot. It jumped from about 80% to 100% in maybe ten minutes. I've seen jumps much more extreme.
I've had it happen to me too when I connect my nook to the pc with the usb cable. It will only jump to 100% if the battery level (for me) is above 80% when I connected it. Cold fusion, man I wouldn't be surprised with everything that's been done to it. I found when you reboot right after it jumps to 100%, it will drop back down to to what it was.
Yeah, mine maintains the charge level after reboot. At least, it reads as charged still.
I'm saying bug, not that it couldn't be cold fusion Obviously there are a few things you could do to see what is happening but I think the fun experiment would be to run down to something like 20% and then try what you have been doing. If you go from 20% to 100% it shouldn't take very long to see how it runs down if it is a bug.
Maybe it will correct and show 15% very quickly, maybe you'll see the percentages drop like seconds on a clock as it reports accelerated discharge or maybe you'll get a low battery warning at 95%! I am curious to see what it does.
Most likely it will just be wrong and shut down when it doesn't have enough juice without really giving any indication what it is doing. But we can hope for something more exciting

Okay, I just had it happen again, and it is happening during adb push,
Maybe my computer is sending the update and throws in 1000 mAh as a tip.
Does this happen to anyone else?
Now that I think I know when it is happening, I will try and replicate it when the nook is at 25% or so. Then I will collect my noble prize. (If b&n tries to claim it, you guys will have my back, right?

Interesting thread. I think it would be a noble prize rather than a Nobel as I suspect even B&N haven't found a way round the laws of physics.
I suspect the battery calibration is somehow getting mangled during the push somehow. What is quite interesting is that the battery monitor widget screenshot does show the charge at 100% whereas the battery voltage has only recovered a little bit. As the previous history indicates one should be getting close to 4200mV when the battery is really fully charged. Li PO batteries normally show a reasonably linear discharge curve from about 4200 at 100% down to about 3600mV when they are exhausted.
What, does the noble prize not have as much money, or something?!? Grumblegrumbleauto-correct-grumble...
I have wiped battery stats, rebooted a couple times, and have been using the nook...now at 93%.
It was at 78-80 before the miracle.
i personally would try using the Die Hard battery Calibration script and see what happens...
Yeah...you thought this thread was dead, but no.
Although I am unfortunately beginning to lean away from it being cold fusion. This time it happened upon connecting to ADB, no push or anything. That does kind of sounds Ike a bug.
But I did leave the whole history up for your perusal since the miracle energy. It's been a couple hours maybe. I was around 80 when it happened and I am just back to that level now.
You can see by the green portions, I noticed the miracle battery increase after I disconnected and it happened again upon reconnect a few moments later. Although to a much smaller degree as I was still running on a magical-miracle full charge.
I posted about this a while back.
With some microUSB cables, connecting the NC to a PC will munch the battery stats file and show instant 100%. You then have to leave it and let it charge fully and reset the battery stats using a battery calibration app or some other method. This happened to me using more than one micro USB cable, but I have several that do not do this. Given the pain it is to fix this problem, I just decided not to ever connect my NC to the PC again... wireless ADB and manage it over wifi instead.
Yes, there's some weird bug with this, it's been this way since day one. You'll see the level drop off drastically in steps.... It'll look normal, then boom, -10%, normal for a while, boom, -10%, etc...
Ah, so it just comes out in big chunks. I was wondering how it would eventually have to account for the discrepancy.
I had forgotten about this thread, sorry. But the heart remembered, so I have one last screenshot.
I never could actually catch the device catching back up, it seemed to just ease its way into it, if at all. But the other day I had the "instant charge" happen again. Later I flashed an update and left it in CWM for a couple hours. After flash, the system corrected itself. Have a look, the flat line is CWM.
I think I may have to return my noble prize.
