Hi,
My phone goes to 99% charge without a hitch but wont go to 100%
At 99% battery my i got 4207mV
All i did was to follow the instructions on this thread
http://forum.xda-developers.com/showthread.php?t=1198333&highlight=battery
Before that 100% is no problem and after that stuck with 99%
and one more thing my phone shows me messahe on lock screen that phone is fully charged unplug but when i see the battery its just 90%.
From 90% onwards i see unplug message.
I am using Alien#4 ROME and Atrix-GB-Kernel-0.1.7-ext4-sv Kernel
Any suggestions or i am just over thinning ?
Same thing continually happens to me. I've done all the "fixes" and suggestions..and it still does it. Sometimes it goes up to 100%..sometimes 95%. All's I ever do is reboot with the phone still plugged in and "usually" (not always), it boots up showing 100%. IMO there is something with GB that is causing it..cuz i've noticed it on every rom i've tried (Alien, Cherry, CM7 etc)..
=>
Same here. It won't charge past 89%, and it did the same in the past at 92/93 %. I fixed it with a hard reset, but don't feel like doing that again.
Sometimes when I disconnect the charger, the phone still acts as if the charger is plugged in. Only solution is to reboot.
I will try to reboot with the charger connected to ser if that fixed my battery metter. Thanks for sharing.

Another thing i've done (as per xploited's thread), is when phone is fully charged reboot the phone (while still being plugged in) and pop out the battery right away. The phone will reboot with a ? (looking for the battery)..then pop the battery back in and it will usually say 5%. Leave it charging until it reaches 10% (i've never gotten it to go higher)..at which point unplug and reboot your phone.
Just read this interesting tidbit from another thread:
"Recently i have tested "Battery left widget", a market app.
When i go in "Summary" and "History" and "Sensor usage" option, i see this :
Sensor is activ "all the time" since last "plug on wall".
Sensor is in use by "Android System"
I have test this :
Charge 100% (and calibrated with CMW wipe battery or "BatteryCallibration" app before), unplug, and REBOOT.
This manual reboot stop "Sensor" activated by recharg.
After this simple action, battery drain has disapeer, and "sensor" activity too
Battery drain is the same than Froyo, 1 day in suspend mode, 1 hour game, 1 hour web and 15% battery left. It's magic !
I think, System detect the wall plug, and activ "something" in system nether desactivated after unplug.
Reboot is the only way to stop this sensor, and baterry drain"
So basically..after fully charging your phone..reboot with it unplugged and it should eliminate some of the drain people are experiencing. Until a new version of GB comes out..I think we'll all have to deal with these weird battery issues.
same issue here with alien 4
it was all good i used to get a very impressive battery life. but after i put alien 4 ( before that i used first ken's release of GB ) the battery life is worse and it doesn't charge till 100% and the drain from from 98 to 90 is very quick compared to other drains in range of 10%
With the 1% mod your phone thinks that the battery is at 100% while at 95%... like 94% would be 90% so it would take a while to get to the full 100 because it doesn't want to overcharge the battery and damage it. Also don't worry about the 100% 4200mv is the normal capacity of the battery's cells aslong as it that or over its still fully charged
Sent from my MB860 using XDA App
As mentioned above, you're fine if you're at 4200mv. Ymmv because of battery. And the juice is calculated by software. No chip on the battery. If your mv are significantly under 4200 mv then you need to calibrate. If it's close or over, quit worrying and rebooting and just use it. Sometimes my phone flies through 90's but after that it settles down and everything is normal. If you keep trying reset battery stats your battery is not going to calibrate because you're not discharging enough for the software to figure out more accuracy with numbers it gives you.
I voided my warranty.
Without any thing doing battery is back to 100% charging
Yep, what the other posters wrote is right. To summarize:
1. If you are at 4200mv, stop worrying what % it shows, because you are at full charge.
2. Android software tries to keep the time when battery is @100% to a minimum, because fully charging and completely discharging on regular basis hurts the battery.
3. The battery meter is lying to you, and it's not such a bad thing, read the article -

Slight oddity with my Vibrant.
Occasionally when I charge the phone, it will show that it is completely charged--battery gauge will show full, About Phone will show 100% charge, all of that good stuff. When I unplug the phone, my battery gauge will instantly drop to 97%.
Additionally, for the entire duration of this particular charge, my battery life will be total crap. And by total crap I mean draining 1% in five minutes with the screen off, going from 97% to 78% in two hours with the only use being a quick check of bus schedules.
However, if I notice this 100-to-97 instant drop and plug the phone back in until it charges to 100% again, it will not display any of this odd behavior and battery life is awesome as usual, with standby power consumption at 1-2% an hour.
So... what gives?

Dont worry about when you unplug it, its just a inaccurate reading.
It happened to me this morning with Axura, and my battery showed 97%, but the 3% was given back without me knowing, does your phone stay at the 97 for a longer time? it should, and also some people say do a battery calibration.
its like
charge till' 100
drain it to 0
charge till 100
and then on clockwork recovery go to advanced and do wipe battery stats or something
^ im not sure someone correct me if i'm wrong about the calibration.
I conditioned this battery after flashing the ROM last month. You have the directions mixed up... should charge to full, boot in clockworkmod, delete battery stats, reboot, drain to 0, charge back to full.
And no, it doesn't stay on 97 for longer than it should; as I stated in the OP, if it does the 100-97 drop, the battery life is significantly worse than when it acts normally.
I get the same thing. Actually at the moment I am trying to unplug... see the 97% and plug it back in, it will then say fully charged, I unplug it and it says 98%. I am going to repeat this until it actually says fully charged when I unplug it and then reboot to recovery and wipe the stats.
What I am confused about when it comes to reconditioning and wiping is even when the phone says "fully charged" when I reboot to recovery and wipe, once the phone has rebooted it says it's charging again. Should I leave it in until it says fully charged or unplug it after it boots?
It seems to do the 100-97 thing primarily when charging via USB. Almost every time I've seen this happen was when it was charging off my laptop.
I've noticed also that when it does this, the battery icon (I use Segmented Battery Mod) shows "100" solid without a flashing plug icon. If I unplug it, it will drop to 97. If I plug it back in and it actually charges completely, it will flash between the plug icon and "FULL."
hmm...mine does it no matter how I charge it.

Mine USED to do thar with Nero beta 3 now on Axura IRS dine I've been using it for 20 minutes and still at 100%
Sent from my SGH-T959 using XDA App
Updated to Nero v3 and now I have the problem constantly. It will always claim 100% charge when it isn't actually fully charged.
Sent from my SGH-T959 using XDA App
If you've flashed the ROM, do the "recondition" -- or if you have a stand-alone (external) charger, just charge it full, then put in the new battery and wipe your stats. (The recondition thing -- charging, draining, then charging -- is just a theory that on the second full charge you'll get "more" charge in there after a full drain -- I doubt this is true, especially if your battery stats are hosed to begin with.)
As for the dip after you unplug it -- this is just the battery manager varying the maximum charge level to optimize battery life. Laptops do this all the time -- even when they're plugged in, they'll let the machine run on battery power here and there. For a new battery it might only let it dip to 97%. On one of my laptops it has decided dipping way down to 86% is optimal. Just depends on the battery health, usage patterns, etc.
Battery life was pretty bad when I first flashed Nero, but now that I've wiped battery stats, the battery life seems much better. It still does the 100-97/98 thing, so I'm guessing it means my battery is still pretty good despite all the heavy use!
The JL5 modem seems to have worse battery life than JK6 (only very slightly though) but it doesn't get stuck on EDGE like JK6 did... net gain in my opinion.
No matter how long my g tablet is plugged in,
it does not charged until the battery meter says 100%.
It always get charged upto 96%.
Is there anyway to fix this problem?
Is it something that can be fixed by clearing batterystat.bin?
If that so, can I do that using adb? Thank you.
khunny,
This is pretty common with the G-Tablets.
You can run it down all the way and then go into CWM and tell it to reset the battery stats.
But often as not that doesn't change much.
My personal advice (I have one that often does the same) is just ignore it. If it's 96%
you've got no problem and at less than 10% you better be thinking "charge."
Rev
Mine only charges up to 96% as well. Gonna try to reset it in CWM after it drains. Hopefully it works, cuz while having it only go to 96% isn't a huge deal its something I would like t be able to fix.
search is your friend
It is normal. Gtab treats 8.3V as 96%. In theory, 2cell li-ion battery 100% of charge is 8.4V. But, such battery does not like to be overcharged (it will shortened battery life).
mine did charge to 100 percent before installing vegan 5.1 supplement? Now it charges to 98 no matter how long i leave it plugged in? There has to be some way to alter the battyer stats to show 100 percent if it is??
Mine finally got to 100%
I had this tablet only for a week or so. I have installed Vegan 5.1.1. I noticed the battery only charged to 95% or 96%. I have drain the battery all the way, and then "Reset Battery Status" in CWM. But, it did not work the 1st time. Then, I drained it again. After the tablet shuts off automatically, I would push the power button to turn it on a few times to drain it more. Then, I reset the battery status in CWM, AND, I "Fixed File Permissions" right after the battery status reset. Then, reboot the device, and it reached 100%
Note: I drained the battery at work, tried to turned it back on about 3 times after it shuts itself off. After I got home, a few hours later, I turned it back on one more time, and the battery showed 2% and stayed on for quite a while. Not sure why that is. Hope this helps.
If I keep my phone on charging even after its on 100%, it starts rolling back. As in from 100 to 99 then 98, even if its pluggen in.
Don't know what kind of a problem this is, hardware or software.
Or there's some issue with the battery.
Please help.

I know the reboot helps.
But usually I put it on charging at night before sleeping.
And when I wake up in the morning, the battery % becomes even less than what it was when i plugged it in.
I'm usually in a hurry then to leave for college in the morning . Can't go to college with battery % less than even 10
Thanks for the reply anyway !

Maybe You have some program that syncs something all the time. Did You try to turn off data and wifi. You can always check it if the reason is the hardware or Software. Just make a backup of Your whole ROM, delete the data and leave the phone over night. I hope it is only software problem.
EDIT: Does Your battery go hot while charging? Oh, and try to wipe battery stats

Maybe there is really some program that is causing that. I had this problem rarely so I never cared. I had one program called Batterymonitor or sth. like that and it was the reason. Do You have such a program, that shows Your battery level or temperature?

Sent from my X10 using XDA
The x10 charges the battery to full then if still plugged in it will stop charging until batt drains to set level ,then will charge to full again and over and over all night. X10 wont over charge batt when left plugged in. Kernel/bootloader handle this. There is an app current widget that can log charge levels.
EDIT: I had a tip on charging here but removed it after further research read more about batt here..

EDIT: the best tip I usr for battery life is, let batt runout until phone shuts off, then pull batt, then plug in charger, then replace batt into phone, then phone will boot, enter xrecovery on first boot and wipe batt stats. After wipe while still in xrec pull batt then unplug. Now plug in phone then insert batt. Phone should boot in charge mode( big batt icon only on screen) dont start phone untill light green for 1-2 hours to get full charge . I do this about once a month, when phone starts to shut off around 15%

As mentioned above as well, this is normal. After charging to 100%, the phone stops battery charging, and will activate charging again only when battery falls a bit (say 97%). Also, battery heating while on charging (and also when using the phone continuously while playing a game) is normal. Relax.. your phone is fine
@ToledoJab
I am having the same issue with battery... phone switching off at 15%, even at 22-23%, when playing a game or something. But switching it back on, and leaving it idle, phone might run for another 2 hours. So it is the extra load while running a game that the phone cant take any longer (i remember getting the 15%,10% and 5% reminders earlier while playing games)...? Does the battery calibrate method actually help in your case? does it go all the way down to 0% or 1% before shutting down.. ?
I just did this after posting that. And yes my phone reported warnings @ 25% 15 10 5 and then shutdown @ 1%.
This way is like reconditioning an old rechargeable ni-cad batt.
All this does is completey drain batt then, with least amount of drainage (phone on, apps& radios running) allows battery to full charge.
There is also a way called recalibrate battery. But this way over charges the batt.
EDIT: I think the phone load will effect reported batt left. I think batt gage use average loads to estimate remaining power. Meaning games, full brightness of LCD, radios -3g -GPS -WiFi -Bluetooth will use more than avg power
edit 2: I found this thread also has some very good points and links. after reading this i will not intentionally take my batt to 0%. I hit 0% about 1-2 times a month on accident as it is. i will just make sure when i do go 0% to wipe stats (dont know if it helps or not) then preform a long (overnight) full charge with phone off.

SORRY for ranting on about this, i thought i was smart but i am still/always learning.
From my XPERIA X10S v8.2 on kCernel @ 1.19ghz
First of all it wouldnt charge past 99%, And then, after one hour of standby it went down to 88%!!
Cm7 official stable release.
Me too no pass 99% :S
Try to download a "battery caliberation" app and do that, also burn it to 0% and charge to 100% while the phone is off..i heard that this might help.
Now i will flash Nottachtrix and do what i wrote Good luck man !

The charging thing is something that is (seemingly) well known throughout the community. I have tried to do the calibration, but it doesn't seem to work that well (at least for me). There is a thread around here somewhere for fixing the issue. I just have never tried it due to work reasons.
The charging past 99% is a known issue with most of the ROMs. There is a thread in here that takes you step by step to get it to display 100%. Basically....
Charge the phone long enough to where you know it should be at 100% even though it is still displaying 99%.
Power the phone off while it is still connected to the charger and then pull the battery.
With the battery pulled, power the phone back on until you see the battery indicator with the "?".
Put the battery back in and reboot.
You will then see the display of 100% with the phone still connected to the charger. The only downside is that as soon as you disconnect the charger, it will drop back to 99%. I have done this multiple times.
You can try the latest nightly: update-cm-7-20120508-NIGHTLY-olympus-signed.zip
I read good things about it.
First of all, use Wipe Battery Stats function at recovery.
1 - Discharge all your smartphone battery;
2 - Connect it to the wall charger and don't turn it on;
3 - Wait till it shows you 100%;
4 - Remove the battery, wait 10 seconds, put it again and keep it turned off;
5 - Wait 30 minutes, keep it connected to the wall charger and press power button till it turns on;
6 - Wait 30 minutes, keep it connected to the wall charger and use Battery Calibration App to calibrate it;
It doesn't make any sense, but sometimes, after step 5, i prefer connect it to usb port in a laptop or computer and wait one hour. It always worked with me.
It might solve your problem .
Wiping battery stats does nothing. it just takes a few charge cycles. If it's a new rom and it's draining fast it's also cause you are probably playing with it a lot

It could be a bluesleep problem... Install CPU Spy App and look if it goes into deep sleep mode. If not, there is a fix for it.
Aside from the OP's issue with the battery draining quickly, why does it matter if it doesn't show 100%?
Nothing can ever 'really' be 100% charged because as soon as you take it off mains it is instantly on the battery at lets say 99.9999%...
As long as the battery doesn't drain quickly I couldn't care less if its showing 99 or 100%.
The problem was that it was draining very quickly to smt like 50% and then it would hold longer...I just wiped everything, restored a neutrino 2.7 nandroid backup i had, flashed the jug fix v2 and now it shows 100%
hi guys! i'm running cm7.2 on my su660 (it's a kang build which is ported from p990 official CM build). and i have a problem on charging the phone. when the phone have 10% of battery left, i plug in the charger, the phone show the charging symbol . but when i leave it sleep and come back after 'bout 3 hours, it still show 10%. but the voltage in sparepart is aproximate 4200 mV. so the battery is fully charged but the rom didn't regconize it. but then after some minutes turning the screen on, the rom show that phone is fully charged. so i guess that the battery percentage counter doesn't work why the phone is pluged in and sleep. so this is a rom issue? can i fix it myself?
PS: sorry for my poor English because i'm not a native English speaker. i'm from VietNam. i tried my best to explane my case. hope u can understand me!
If, after rooting or more likely that case after flashing a new rom, you often have battery reporting errors, and re-calibrating the battery along with some steps I will outline for you below will ensure that your battery is getting a full charge, and the battery reporting accuracy is right on. As far as power cycling, I don't know that it does much good. I run my device in performance mode all the time, and with a CPU overclock of 1.25GHz and various tweaks, I have about a day an a half to a day and a quarter of full runtime from my battery. This is with moderate to heavy usage (calls, emailing, text, gaming, web browsing, etc.) so you should have no problems getting acceptable battery performance after following these steps:
1. Take the case off your device (one of the latter steps involves taking the battery out from the phone while it's plugged in. Make sure your case won't stand in the way.)
2. Install Battery Calibration app from the market
3. Plug in your device to charge while it's on, wait till it gets to a 100%
4. When the charge is 100%, open the BatteryCalibration app and lookup what the charge is in MV while at 100%. Write it down.
My Atrix 2 was showing ~3400MV while at 100%, which is definitely not the maximum capacity.
5. Discharge your device completely until it shuts off.
A good way of doing this quickly is by turning on wifi, and a video player.
6. Without turning on the phone plug it into a wall charger and let it get to 100%
7. When it's at 100%, without unplugging it from the wall charger, take off the battery cover, and take the battery out.
Your phone will "reboot" and show a Missing Battery icon.
8. Without unplugging the phone from the wall charger or turning it on, put the battery back in and wait until the phone recognizes the battery.
9. Your battery should now be recognized by the phone, and showing a charge % significantly lower than 100%.
Mine showed only 5%.
10. Let it sit there charging for 2-3 hours (or more).
My phone wouldn't charge past 10%, but yours might. The numbers don't matter much as the phone is definitely getting additional charge that could have been lost while flashing ROMs, etc.
11. After 2-3 hours (or more), turn the phone on while holding the volume down button and get into CWM (if installed) or use Rom Manager (is device is supported).
Do not disconnect it from the charger still!
12. Wipe battery stats in CWM, reboot.
Do not disconnect it from the charger still!
13. When the phone turns on, go into Battery Calibration app again and look up your MV numbers -if you were like me, they should be significantly higher than before. After this whole process I had 4351MV at 100%, comparing to 3400MV before calibration.
Do not disconnect it from the charger still!
14. Before going to sleep - Install Watchdog Task Manager Lite from the market. Go into it's preferences, set CPU threshhold to 20%, check "Include phone processes", check "Monitor phone processes", check "Display all phone processes", set system CPU threshhold to 20% as well.
Do not disconnect it from the charger still!
15. Make sure your wifi and data connections are off. Now finally unplug the phone from the charger.
Go to bed, let your phone sleep too.
16. Success! Next morning check where your battery % is at and if you followed the instructions correctly / got lucky like me, your battery life should be 90% or more.
I went to bed with 98% and woke up to 94%. So, I consider this mission a success.
