Get battery calibration off of android market (assuming you have root) then charge to the point that battery calibration says your battery is at 4200mV (full charge) and press the calibrate button. Unplug your phone and let it drain to the point that it shuts itself down, then charge completely to 100%.

Alrighty thanks.....seems like the battery might be crap.....doesn't last very long....

I got the extended battery off of amazon, and I get roughly 2 days of minimal usage, and 7 to 10 hours of heavy usage.. that's the 1930mAh battery, not the brick 3000 mAh. Lol

Ya I just ordered one cause I think this batt might be crap

Mine does it also, sometimes. I noticed that happen more frequently if i reboot the phone with quickboot, and not if I do a proper power off and power on.

Ya know my battery is fine from what I can tell

Yeah that's actually lower than normal. Batteries display their median voltages. A 3.7 volt battery fully charged is 4.2 volts, and completely drained (for my battery at least) is 3.2 volts. 3 volts is kinda low, but maybe you have a different phone model or battery.

Battery

I some up this morning and saw my battery was at 88%, it has bin on charge all night how can I fox this so it charges to 100%?
Sent from my GT-I9000 running remICS-UX using XDA premium

"some up"? Ok... go to CWM->Advanced->Wipe Battery Stats ... if doesn't work, do a full wipe or reflash ROM, you are using...

Woke* auto correct lol, and o do this after every ROM flash and this wouldn't affect that anyway, its not done it before, only to 98% or something but I read that it does this it will reach 100% the stop charging to preserve the battery, but dropping to 88% is a bit extreme I think I'm losing like an hour of battery life

This is a calibration problem caused exactly by you wiping your battery stats, you need to leave them alone and after each flash do a full empty to full charge cycle so the stats can provide proper calibration statistics, I have never wiped battery stats in 2 years of owning my phone

I always do this after a wipe, wait till fully charged>wipe stats>discharge fully>recharge fully

Ok, I know the point you are making but I personally think it does more harm than good.... Does it drop straight down the moment you remove the charger?

I don't know if it might be a battery problem, or if the CM9 Nightly build I'm currently on holds a charge really well, but sometimes I charge my phone up to 100%, then after about 30 minutes of continuous, non-stop usage, the battery is still at 99%.
Is this odd behaviour or is it normal?

No it only charges to 88% unless I remove charger then plug it back in again then it will charge to 100%, I think its because the phone charges to 100% then drains then charges, but I think its failing to start charging once it drops to a certain limit (say 10%) so normally it would charge to 100% drop to 90% then charge to 100% so it doesn't damage the battery, but as I said I think its failing to start charging again so it just keeps falling... I need a fix for this? And yes it is a cm9 base

I've always been wondering: is it possible to "damage" the battery or lose some of it's juice by doing wipe battery stats to many times?

Instant Battery Charge Glitch

I plugged in my phone for 20 seconds and I went to check for email notifications and to my amazement it's fully charged.
This is now another possibility in battery issues. I know I'm using a faulty device (that's why I ordered a RMA) but this is kinda odd so I thought I'd share it with you guys.
Let's hope this instant charge sticks lol. I went from 7% to 100% in 20 seconds.

Had that also one or two times. If you leave it plugged in it goes back to the correct percentage after some minutes.
Likewise a minor software glitch that will get fixed soon, nothing to worry.

Good for example you need to go somewhere and you forget to charge it. Just plug it in for 20 sec and bam it's fully charged and problem solved.

This happens when you plug in the phone and the wall charger has no voltage, e.g. because you use a switch that is off. If you switch it on, the glitch occurs and the phone is instantly charged. Of course that's not really the case, though. Rebooting solves this most of the time.

The Galaxy Nexus had none of these issues. I just hope that Google fixes this soon.

this is a non-issue as it is charging fine when left. no disadvantages except when you really believe it is fully charged in a second.

Nope. It doesn't let me continue to charge until I restart the phone (for me at least).

My phone did this last night. I noticed it right away, so I just unplugged the cable and plugged it back in and bam it went back to charging its merry little heart out

I am also experiencing this issue with a Nexus 4 (few weeks old) running Andriod 4.2.2.
Anyone know if this issue is fixed in upcoming release?

Just happened on my Nexus with Nokia 1.2mAh charger and latest CM10.1 nightly, reboot solved it though

I think this is correct. I've had this happen 3 times in 6 months and it's only happened when I plug the phone into the charger right after plugging the charger into the wall.
I've since tried to leave the charger plugged in about 10-20 seconds before attaching the phone and it hasn't happened since (~3 months)

Thanks, will try this approach.

i hope someday "20sec charging" will be a feature for every smartphone

Happened to me one night but when i unplugged my phone in the morning, it went down to 40% :/ so evidently it didnt continue charging after glitching. Battery usage pane confirmed this.
Sent from my GT-N8013 using xda app-developers app

I usually charge my phone during nights.. Sometimes on the morning my battery is down to 80%, it stopped charging at 100% and I assume didn't charge any longer and the phone was draining the battery, has anyone else the same problem?

For me 80% only in standby is too much. I always get Fully charged when I charge it at night.

Strange shut down on Low battery

Hi everybody.. i'm encountering this problem with my HTC one. When I reach the 20 %-9 % range of the battery the one shut down. Try to reboot and shut down again on lock screen.then I'm forceed to put it on charge. Why this strange behavior ? Battery is broken or not calibrated?or a bug? Please help !!
Sent from my HTC One using Tapatalk 4 Beta

If i remember their is a battery calibration file somewhere in the system, if it is deleted it causes the phone to re-calibrate the battery gauge, have you tried a battery re-calibration app from the app store, i think this is what they do.

All stock!
Sent from my HTC One using Tapatalk 4 Beta

If it`s all stock and you dont want to root, all you can do is full charge and then run it till it shuts down a couple of times and hope the battery gauge learns the true battery capacity, if this does not work.
Or you could try charging it to 100% and keep it plugged in, then do a restore to factory defaults while plugged in, then see if that fixes it.
If this does not work, you might have a faulty battery, get a replacement phone.

Found this fix online, see if it works.
Option 2: (No Root) Physical Battery Calibration This option is also very simple, but at the same time, a little more time consuming. If you have a rooted device, Option 1 is definitely the way to go. However, if you don’t know what “root” means, stick with Option 2 and go check out the root section of Android Authority.
Turn your phone on and charge it for 8 hours or more.
Unplug the charger.
Turn your phone off and charge it for one hour.
Unplug the charger.
Turn on the phone and wait 2 minutes.
Turn your phone off and charge it for one hour.
Unplug, turn it on and use as normal. Your battery life should now be a lot better.

4.3 Slow charging?

Anyone else experiencing very slow charge times? I plugged in at 20% at midnight. Just woke up and it only charged to 87% in 7 hours.

Yep, mine been slow to charge as well. Admittedly though I just dirty flashed the update over my previous rom so I will do a fresh install see if that makes a difference.

mine charges faster as a matter of fact
especially while plugged into usb

Same here; I've noticed that battery life and recharging are a lot better.

Yeah, I noticed this last night. I plugged in about an hour before falling asleep, checked it a few minutes before knocking out and it barely moved 4%. Very concerning.

Exactly the same thing happened to me. I just updated to 4.3 ROM, firmware, radio, plugged the charger and went to sleep. After I woke up (9 hours) phone was at 87%. Let it another hour, still the same. Than rebooted and 100%. IDK maybe the new firmware messed smth? I'll try again later and report back

Mine has improved as well, actually. Before, it would take a very long time to charge fully. Especially that 99-100% gap. It would literally take 20+ minutes to go from 99 to 100. Made no sense. Battery charging and life seem to have been much improved since the update.
The one thing that hasn't changed as that as soon as it fully charges, I can still unplug it and plug it back immediately and see the battery percent drop. Usually goes from 100 back down to 96-99%. I have never once, since I've had the phone, had it stay at 100 after unplugging and replugging immediately. Weird.

Mine actually charges faster and I get better battery life. I would do a clean install. Running 4.3 stock with goodies.

Just checked my batter stats and it took roughly 7 hrs to go from 20-100%
