Hiya,
I was poking around the forums a couple days ago and I stumbled across a hack that recalibrates the phone's battery STATUS, it doesn't do anything about helping battery life or anything.
Last night when I was about to go to sleep I had a battery life of 32%. I plugged in the phone, and immediately restarted it. When it booted up again, I kid you not, it had 63% battery life. I turned off the phone while plugged in to see the battery icon, the one that shows.the battery status while its charging with the phone off, and indeed it showed around 63,65%.
Anyone know where I could find this? I think its buried somewhere on the forums.

THIS WILL HELP RECALIBRATE YOUR BATTERY SO YOU DON'T HAVE THAT ISSUE
1.Charge till full when powered on
2.power off
3.charge till full again
3.boot into recovery(adb reboot recovery or Power off the phone and then hold the volume up + Volume down + the power key. When it goes black the 2nd time release the power button and keep holding the volume buttons.)
3.wipe stats by going into Clockworkmod recovery -> advanced -> wipe battery stats.
4.boot and continue to use as normal
Heres 1 from another board:
""So, you are having trouble with your battery seemingly draining too quickly, especially after having flashed many ROMs/Kernels/etc...
It is possible that the problem (or part of the problem) is not necessarily the phone using too much power. If this is the case for you, you should see some results from doing the following:
1. Connect the phone to the charger with the phone powered on, and allow the phone to charge until it shows 100%
2. Disconnect the phone from the charger, and power it off.
3. Reconnect the phone to the charger with the phone powered off, and allow the phone to charge until the battery indicator shows 100% (you can use vol-up/vol-down to make the indicator come back up when the screen goes to sleep).
4. Disconnect the phone from the charger and power it on.
5. Once the phone is powered completely on, power it off again and reconnect it to the charger until the battery indicator shows 100%.
6. Disconnect the phone, power it on, and use it.
You should only need to use this sequence one time.
Hope this helps.-Joeybear23"""

I didn't notice this problem until the day before. My battery status is displaying 70% when the phone consider it to be fully charged.
I've drain it to 5% before charging overnight, but the status still display 70%.
I am not sure if this is a problem with my phone or the battery. Any help would be nice.
Try this but you need a rooted phone for it: http://forum.xda-developers.com/showthread.php?t=722862
it is just a status bar bug
the battery is probably fine
use Gauge Battery Widget instead to see the real stuff
http://forum.xda-developers.com/showpost.php?p=8124361&postcount=46
Thank you for the link!! I am trying that now.
This is not the status bar problem as I've test out some of the widget.
The phone would only charge up to 70% no matter how long it will remain on the charge.
Going into the battery info in setting also indicated it is at 70%.
At this moment I am draining my phone with max brightness and everything turn on.
Start off at 70% at 9:30am and now (2:00pm) is at 3%
So I guess I should try to charge it full with the phone off
Did you recently flash firmware to your phone? Make sure your battery is fully charged whenever you flash firmware because it will clear the battery data. It seems to me all you need is a battery calibration. There is a procedure posted somewhere. IIRC, you need charg up the battery to 100%, power down, charge 100%, power up again and repeat a few times.
I had the same problem.
After a day of charging the battery fully charged notification appears. As soon as I unplug it the battery immediatly jumps to 70%.
Is there a way to fix this? Perhaps reflashing when the phone is fully charged (which is currently 70%).
I tried the rm /system/data/batterystats.bin but did not remedy this problem.
Same problem here. It has been this way for a month. Tried calibration, different batteries, different ROMS....everything.
who can help?
using alternative battery widget is not an option if battery stats from settings also displays 70% max
this is very unusual problem - i would suggest:
1) install https://market.android.com/details?id=com.nema.batterycalibration (phone needs root)
2) drain battery to 0%
3) take out battery for 5-7 minutes
4) put it back and turn on and drain again
5) repeat untill phone will not turn on
6) while still off charge phone to 100%
7) disconnect charger power on the phone, let it boot and use the battery calibration app
8) now let the phone discharge with normal usage untill it powers off (do not reboot, power off during discharge)
9) put the phone to charger, turn it on and let it charge to 100% wo reboots/poweroffs
should be fine
let me try tomorrow..I have similar issue..

Hey Somator, I am trying your tutorial now. I drained my battery to 0% on my phone. I then would boot it up, it would register 1%, then turn off.
I then put my battery in a coworkers phone today and it read 40% when it previously read 0% on mine. So I depleted the battery on his phone, reinserted it into mine, and I am now currently charging it to 100% while it is off. I will let you know how the rest turns out.
I have tried calibration procedures on stock rom, MIUI, CM7, I9000, and I897 Roms.
drain the battery on his if you can and then charge on yours
after that wipe battery stats with https://market.android.com/details?id=com.nema.batterycalibration
//edit: oh you did exact that - well should be fine from now - still wierd why it just 'decalibrated' by so much in the first place
the original charge has helped me, everything is fine
In case someone is looking for an answer here (considering this is the thread that comes at the top of Google's search results), this is what worked for me:
1. Take the battery out.
2. Plug phone into wall charger.
3. Put the battery back in the phone.
4. Let it charge for an hour. Mine said 5% the entire time it was plugged.
5. Remove phone from charge. Remove battery. Put them all together again.
I hope this works for others.

I have Verizon note 4 that can not be rooted, any other options?
I just got my captivate and it is clean except from root and sideload and have lead to my first issue. I put my phone on charge over night and went to bed. Then after I woke up I unlocked the phone and saw the phone fully charged sign. I then checked my battery percentage which indicated 100, but when I pulled the charger out it shows 59! I rebooted but it still shows it and I pretty much am sure that it is really 59 and not a miss reading. But why did not fully charge? IS there a setting that I did wrong because my hunch is that when the fully charged sign comes, it stops charging (the zigzag on battery goes of) and the battery drains and the phone never charges again. This is really retarded implementation! Does anyone else have the same problem or any solutions?

EDIT: PLEASE DON'T POST ANY RECALIBRATION THREADS IT IS NOT AN ISSUE ABOUT CALIBRATION (HENCE I HAVE DIFFERENT ISSUE ON THREAD TITLE) THE ISSUE IS FURTHER EXPLAINED THREE POSTS BELOW.
Have you tried any of these methods?
HOW TO: Reconfigure Battery Stats
When you flash a new ROM it may be necessary to reconfigure your battery stats.
Signs you may need to re configure:
1. . Using more then 10% battery in an hour or less
2. . While plugged into the charger you lock screen shows a different percentage charge then the battery icon
3. . After a full charge your battery icon only shows 99% and quickly drains.
4. . Any general weird battery activity
Step by step battery reconfigure process: (This is the process that has worked for me time and time again with ROM after ROM)
1. . Flash the Rom on a full battery. (skip to step 6)
2. . If you flashed on less then full plug into AC charger asap and charge to full while the phone is powered on
3. . Once the phone blinks full 2.1-battfull popup shows 2.2-battery sign shows on left of notification bar power off
4. . Charge till full while powered off. the phone will vibrate and the green battery will show 100% in white text
5. . Unplug phone and power on.
6. . Using Root Explorer or a comparable program navigate to (Mount R/W first): data>system> and delete file batterystats.bin
7. . Reboot
8. . While the phone reboots it will rebuild that file and the software and phone should now match.
9. . If any of the symptoms persist start at step 2 and repeat.
10. . As with any rechargeable battery fully discharging the battery once in a while isn't a bad idea
HOW TO: BATTERY Calibrate
1. Connect the phone to the charger with the phone powered on, and allow the phone to charge until it shows 100%
2. Disconnect the phone from the charger, and power it off.
3. Reconnect the phone to the charger with the phone powered off, and allow the phone to charge until the battery indicator shows 100% (you can use vol-up/vol-down to make the indicator come back up when the screen goes to sleep).
4. Disconnect the phone from the charger and power it on.
5. Once the phone is powered completely on, power it off again and reconnect it to the charger until the battery indicator shows 100%.
6. Disconnect the phone, power it on, and use it.
You should only need to use this sequence one time.

Ill try that but the thing is that I didny flash any roms so i don't know if it is a calibraion problem. Also can anyone confirm that the battery stops charging once full while connected into charger?

PROBLEM
EDIT: I did some more searching and found that some people said they have this problem and some people don't?!? Pretty much what happens is that when it hits 100% it stops charging so then it drains over night without charging again. This is STUPID! But just to make sure this is a stock problem I want to test if this happens to people here. Can you please post if this happens to you or not? (also post if your on a custom rom)

It's never happenned to me stock or custom ROMS, it really looks like you need to callibrate your battery. I've experienced a similar issue as you and a simple callibration fixed it. I've never had it stop charging when plugged in after a full charge.

Really??? Ok I will try recalibrating, but I don't know how my calibration got messed up since I really didn't flash any roms.
I think ( dont know for sure) this happens when you first get the phone and do not charge it fully before first power on. I think android stores this half chrged battery as full and starts the cycle from their so it never actually charges.
i would use rom manager delete battery status pull battery for 5 min then put battery in and charge from the wall till it sais full and repeat this over once

Ya thats actually a likely explanation. Recalibrating now. Almost to the point to remove battery stats.
Hey all,
Noob question. I recently went to JVP (doc kitchen) and tried out multiple kernels (speedmod, fugu, tegrak). I only noticed this issue after going to tegrak's kernel so suspect it's kernel related.
The issue I'm having/suspect is that after "100% charge" the battery would start to be consumed (even if it is plugged in). This is most noticeable if I'm at my desk at work all day (phone on charge) or when I leave my phone charging overnight. When I disconnect to go home/go to work, I can see the battery is at 85% or similar (as if the phone wasn't on charge). If I was to disconnect it as soon as it hit "100%" it'll be at 96/97/98% as expected.
I'm not an expert and logcat confuses the heck out of me to be honest, but would anyone know what strings I can search for to determine if the phone "stops charging" when it hits 100%? I'd prefer it to be on a trickle charge (ie keep the battery at 96/97/98%) so that when I disconnect, I have a near full battery.
Is this a kernel issue? or a battery level calibration issue?
TIA

Please do this procedure and see... once u finish ur 2 or 3 cycle u'll get the result...
- Charge your battery full, bump charge to get the highest level possible ; note that it's not a big deal if it shows 97% when you unplug after bump-charging
- Drain your battery to 0% until it shuts down by itself (without plugging the charger or connecting the phone to a pc)
- Wait 2 minutes and reboot the phone to ensure the battery is completely flat (it might reboot fully, half way, not at all, don't worry) until it dies again
- Remove the battery and wait 2 minutes
- Replace the battery and plug the charger without switching the phone on until it shows 100%
- When phone shows 100%, boot in recovery (volume up + home + power) and go to > Advanced > Wipe Battery Stats > Confirm (move up/down using the volume keys)
- Reboot the phone and unplug the charger when the "battery full notification" comes (wait for the notification before you unplug the charger)
- Now use your phone until the battery is flat again and charge full (no need to have it turned off, unless you it to charge faster). Repeat 2 or 3 times and your battery will be calibrated
- Only wipe battery stats once, run a few cycles of full charge / discharge and after that just use your phone as normal (i.e. no need to deplete / charge fully anymore).
My phone has had boot problems lately, and I'm wondering if it is a hardware issue....
I've charged the phone when it is turned off (meaning that when you tap the power button, the white screen with the battery icon pops up). I've charged it to 100%, unplugged it in the morning, and when I come back at night, the phone is at 0%.
Does that make sense? Is the phone not really off if the battery charge screen shows up when you plug it in?
If it's draining from 100 to 0 in a day with the power off, it could be hardware for sure. As long as you're sure it was full when you unplugged it.
Try with it on and install gsam. See how long it lasts on...
And what gsam says before its dead.
So my turbo just turned 2. For the past 6 months or so been having some weird issue. I was on RR Remix for a while, then went to CM14 by BBH27 for a while, and then back to RR, and now on ComputerFreak Stock. I don't have any issue with charging the phone. Quick charge works just fine.
I have had issues where the battery will just be dead even if it was at like 50% and confirmed charging.
I thought maybe it was my stupid charger (I have another that I have yet to test) but then last night, after charging my phone before I went to bed i unplugged it. I woke up around 6:45 to find my phone once again dead. It looks like around 2 am the battery just fell. Dead. Just gone. I go and hit the power button and i got 1%. The battery graph looks as if i turned the phone off. For the most part my battery last all day 12+ hours with some good usage too.
I'm getting ready to flash back to stock now that full stock MM is out now to flash and see if that makes any difference.
For what it's worth, my Turbo would just straight up shutdown when I was on RR. And not go through the shutdown process, just crash to a powered off state. It would happen if the battery was full, low, or anywhere in between. I don't know if that's the issue you were experiencing, but I suppose it's possible.
My daughters is having the same issue.
Anyone have a solution?
I've tried clearing caches, battery recalibration, etc.
Going to see about doing a fully clean install tomorrow if she is okay with it.
When this happens and the phone just shuts down, does the battery percentage immediately jump back up when you plug in a charging cable? I was having that problem when using wireless charging a lot. It turned out be a battery calibration issue. You can re-calibrate by holding the power button and KEEP holding it when the "Power Off" dialog pops up. The phone will eventually reboot itself then leave it overnight on the factory turbo-charger.
One warning - Since the marshmallow update, performing this procedure seems to wipeout your BT connections.
