Help! Battery won't charge past 70%

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

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.

Please help with battery charge issues (differt issue than normal)

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.

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

[Q] USB charging bug in 2.3.3

Hi
Apologies if this has been posted before. I recently flashed my phone with gingerbread (JVK) and since then, the USB charging have been more then a little bit screwy.
Usually i have my phone plugged into my PC while i am work. At some point during the day i will get the message telling me that its finished charging. If i unplug it at this point the battery will instantly drop to between 70 and 80 percent, sometimes it goes as low as 50%!!!! If i plug the phone back in it will continue charging for a while and then i will get another message telling me that the battery is at 100%. If i unplug it then it still drops, but to a higher percentage. I am able to get the battery to 99% by plugging it in and unplugging it a number of times.
The odd thing is that if i charge it from mains, it goes to 100% and stays there the first time.
Any ideas?

somehow same issue for me for what ever gingerbread (jv1/jvk/jvb) i have use.
but mine is different, if i got it unplug immediately after it saids "full charged" it will shows 100%.
BUT if i leave the charger on after it saids "full charged" for another few more hrs say 6 hrs, after unplugging.. it will immediately drop to 90% or even less some time.
well for js5/7/8 don't have such issue, that means after i leave the charger plug for overnight even its already full charged, after unplugging it still shows 99-100% !
wondering if any jv1/k/b user encounting this same issue?

If you are rooted, then delete battery stats, shutdown your phone, and leave it on the charger till it is 100% full. Then leave in on the charger again, start your phone, and delete battery stats again. Reboot your phone, and you should be ok.
For the second part, in which your phone after fully charged and left on charger lost some percentage after unplugging, it seems that Gingerbread stops charging once battery is full, and do not continue, even if charger is plugged in, once it'll lost some power. Some older phones does this (S45 for example).
Out of curiosity, what kernel are you using?

ok, as for battery stats i did the wipe, but i did not shutdown and do a full charge
as for kernel i did not really try on stock kernel though, i started using jv's series with CF's kernel or supercurio's hacked kernel.
maybe you are right that gingerbread stop charging after the battery is fully charged, but to my understanding i thought that is supposed it run on a/c once its fully charged? leaving the battery disconnect until you unplug it and it will starts to use the battery.
for froyo wise i presume it runs on a/c while leaving the battery disconnected, after overnight of full charged the phone is cool and don't feel like the battery is still "charging" after it reaches 100%

I had this problem too when i was with xxjvk. batterystats.bin was always automatically deleted by system once charger was connect/disconnect (couldnt remember...).
if the charger was unplugged right after fully charged notification, the phone worked perfectly fine and battery life was much better than with xsjw8..

Ok seems like jvb doesn't solve the issue... I'm on goatrips's jvb at the moment. I got the make sure that I unplug immediately after it said full charged otherwise the percentage would drop like 10-20% if I leave it connected overnight.
Wondering how come there is so many jvk/jvb tester/users around but seems no one mention about it.

Thanks for your reply but i have already tried this.
It also does not explain why it is fine charging from mains but not USB.

Notice that. Not sure whether its a bug. When it finishes charging, the sgs operate naturally and doesn't preserve the battery like it use to in the previous fw. So it drops immediately as the phone is disconnected. If the screen is left on during charging, it is a problem...

Anything ever come out of this? I'm using Serendipity VII for Cappy based of jvb. I'm seeing this regardless of the type charger I use. Once it hits 100%, the battery continues to show 100% until I remove the charger. Then it shows what I assume is the amount of battery left after powering the phone from the point it reached a full charge to the present. If I remove it immediately after full charge is reached, it reflects that. If I leave it on the charger for hours, it immediately drops reflecting the time spent since full charge.

Seems to be phone battery calibration, happens to me too. Try not to unplug the charger immediately after 100%, let it overcharge for few minutes more.
Sent from my LG-P970 using Tapatalk

Also happening to me... It's because battery calibration...

This is the normal behavior of overcharge protection.
imagine you battery is charged till 100%, the overcharge protection now disable charging till the battery is loosing a few % of its charge, but the "battery memory" doesnt recognize this respectively doesnt refresh its state so your battery indicator will always show 100% until you unplug the phone.
if you unplug the phone at 100% it might be, that the battery memory is refreshing after loosing one more % of charge and now recognize, thats it wasnt at 100% at all and show you the current charge.
e.g. if you charge your phone when its off-state, this behavior shouldnt take place and the phone should charge till exactly 100%. important for recalibrating the battery.

Here, if you have root use this
https://market.android.com/details?id=com.liteup.calibratebattery
You can also load up clockwork recovery anf clear battery stats.
If no root access, fo the following.
1.Power on let fully charge
2.turn phone off while still plugged in
3. Remove battery and power cord and push power button for 5 secs
4. Replace battery amd power cord
5. Let fully charge again.
Once charged, power up while pluged in, once phone is fully loaded un plug and monitor battery,
None root battery calibration should be finished.

When it happens to me... I inmediatly replug the charger and wait... the second time I umplug I get 100% and It seems to repair the issue for the future charges.

i noticed this too! sometimes i do get 100% after charging. But most of the times its 98% immediately after unplug! And i have my battery calibrated too!:/

same issue

any solution for this guys?. I've calibrated my battery so many times and it is not fixing the 98% charge when unpluggin

mine's not...
try screen-on charging...
go to settings>deveLopment>check stay awake(charging)
if you're in Gingerbread version (2.3.4) when battery reached 99%, you"LL need to wait 1 more hour to make it fuLLy charged...
that's it!
tried and tested by most android users...
just charge it without using to avoid excessive heat of your device... :good:

What about first time using battery? Charge the battery 100% first or let it drain to 0% then fully charge?
I bought 2400mah battery, but cant get significant performance, fully charged first time use..

I think you were ripped off.

[Q] Help. Battery will not charge more than 70%

I am not new to the phone and I have done battery calibrations many times. I used MIUI for a long time, then went to Pinnacle 1.1. After a few weeks one night after fully charging, I unplugged the charger and it dropped to 70% instantly. I could then plug the charger back in and it will not move from 70% for a while, then it will register 'fully charged'. Removal of the charger again will make it drop to 70%. Turning off the device and charging will show the green battery about 2/3 full, but not registering full. I then went back to MIUI thinking it was a rom flaw, but this problem has persisted. I am right now charging on stock JF6 with the same results. If this is indicative of a defective battery, has anyone seen this before? The battery is 14 months old.
TL;DR - It seems that the battery wont charge past 70% regardless of ROM/Kernel.

I had a similar problem but it was because I wasn't using the charger that comes with the phone switched chargers problem was solved.

Tried that. It hangs at about the 2/3 full level on the large green battery icon when the phone is charging off so I really can't do a proper bump charge.

I find that hard to believe, but it can't hurt to try!

Sounds like you need a battery calibration..
1. discharge completely
2. plug into a USB port on the computer for a slow charge up to 100% (overnight while "off")
3. unplug the device and turn it on
4. if you have a ROM with CWM installed, clear the battery stats at this time.
5. plug it into usb until it's charged to 100% (while on)
6. unplug the device and turn it off
7. plug in into usb again until its charged to 100%(while "off")
8. turn it on and use it as normal
This will allow the device to relearn it's battery charging characteristics. This is the battery calibration.

You are not leaving it long enough. It will reach 100% once it charges what it believes is 30% more. It must be off and you must clear the Batt stats.

Once it stops charging it marks that as fully charged. Your battery needs calibration.

You are right.
I did a small test with a coworkers battery today.
His battery in his phone - 88%
His battery in my phone - 58%
Leaves a delta of 30% which is exactly why mine stops charging at 70%.
It has gotten to 100% while off charging in the green. I then booted to CWM recovery and wiped battery stats, but it turns on at 70% again. It is almost like it isn't deleting the file.

It's true, go to your nearest AT&T store and tell them about your issue and they'll take your information (name, address etc...) and ship you a brand new OEM (Samsung) battery no questions asked. No idea why they don't just hand you one on the spot, but it only takes a few days to get to you anyways.

You are right.
I did a small test with a coworkers battery today.

did you finish the procedure I mentioned? There is a calibration procedure. It involves turning it on and off several times and plugging it in an unplugging it several times.

I followed the calibration instructions perfectly. I have done it quite often actually. Didn't work. It acts as if CWM isn't actually deleting the file.

Deleted batterystats.bin via a terminal emulator and still no luck.
