I tried searching for similar posts but didn't found actually one that had clear instructions on how to clear/calibrate/reset the battery , i have this isse with it that every time i charge to full and disconnect the charger the status of the battery changes to 97%, also i notice just now that the battery went suddenly from 32% to 22% and when i put that charger back it went back to 32%... strange
many thanks for helping

Hi all,
Few days ago i've received a new battery for my nexus.
I'm not sure now it was a good idea, but i've reset battery stats (by recovery) and proceed to a bump charge, then reset stats again.
I've done it twice because the first time, charge process jump from 55% to 22% and was stuck at this value. (bump charge and reset)
Now, my battery life is quite good (around 20 hours) but battery indicator is crazy.
Just after being unpluged, its drains quickly to 27%, stuck at this value for a while, then drains again to 2% and do the same.
What can be done ?
Wipe and reinstall cm ?
Thanks !
wrong thread to post to mate...
but anyways try reinstalling ROM and using battery calibrator to calibrate battery if your new battery allows it...
Hi there
i bet this is the 1290312 thread about batteries but i can't find the one that suits me.
so here is the deal with my alfs06 and gingerdx021 x8: when i am charging my phone, the percentage goes high reeealy fast. when it reaches 99% it stays there for a while (30min) and after that it is completely charged.
i was thinking that i have a problem with battery calibration, but i fully charged my battery and then deleted battery stats in CWM, but still no result. what do you guys suggest?
fact: if my battery display is, let's say 16%, if i reboot my phone it goes to 19%.
after batterystat wipe you must charge the battery 3 4 times to calibrate it. it will takes a while.
thanks for your reply. i will charge it and post after a few days if the issue persists.
i bought my galaxy note 3 days back. except for battery issue , everything else is fine.
problem - charging drops below 85% from 100% immediately after unplugging. this happened yesterday and also today....i charged the phone while sleeping ( 1 am to 8 am ).....charging dropped from 79% to 100% imediately after unplugging....
i could use some advice about correct charging methods - can i charge the phone when battery is 50% drained or should i wait for the battery to completely drain??
with lithium based batteries you definitely do not need to completely drain the battery before you recharge it.
As I understand it there are two possible explanations here:
1) Your battery is broken. If nothing in 2) helps, get a replacement battery.
2) Your battery stats have gotten screwed up somehow.
Depending on what version of android you're on this can be fixed by either:
a) doing nothing for a few days and seeing if the stats start behaving normally. I would recommend you start with this.
b) wiping your battery stats. There are a bunch of apps that can do this, or you can do it from CWM.
If you do wipe your battery stats, your phone will probably report weird battery usage for a couple of days. See a).
Hope this helps.
hello
i just wanna ask something about my battery life on my x8...here's how it goes first i fully charge my battery up to 100% until it says on status battery full...then i unplugged it..after it i texted for a few minutes...and i check the status of my battery and it says: 28 mins 23s on battery..my battery is on 96%..is this normal.? or somethings draining my battery,?
i use minicm7 2.2
this is normal since battery is heating itself while charging, and when it cools down it shows less percentage of itself... to maximaze your current battery life, calibrate the battery:
1. charge it to 100% no more no less
2. leave the charger PLUGGED IN, and reboot to CWM
3. there you should find somewhere under options or advanced "wipe battery stats", and you press that
4. reboot your device and when it starts up it will show about 91%, charge it to 100% and you have your battery calibrated
NOTE: the charger is always plugged in
ok thanks i'll try it... one question should i drain the battery before calibrating it.?..as in zero percent??

Yes , that is recommended.
Also , one advice from me.
Even after calibration , whenever your phone says 100% charged , reboot it while the charger is plugged. You will get the exact battery charge after reboot.
Do it every time your recharge your phone.
Then stop rebooting when you get a 99% or 100% after a fresh reboot. Trust me , it helps.
ok thanks for the advice i'll try that too...
it is normal dude ....mine is giving 1day on heavy use
use zepplinrox's supercharge script...it really made a CONSIDERABLE change to m battery usage time
I have one question: "Why my battery is giving 6-8h. My battery 2 days ago giving 24 and more hour." Sorry for my English, but i am from Poland
what happened 2 days ago? did you install new ROM?
The OP might not have needed to install a new ROM, just an APP or maybe just a combination of APPs running. My phone sometimes canes the battery in a couple of hours from 50% to nothing for no apparent reason. On both stock and custom (actually better battery life on custom) it lasts about a day but sometimes about 6 hours! Not sure what is going on as this happened on both the stock 1.6, 2.1 and the custom 2.3.4!
Hey guys, its my first post on this forum (or on any forum for that matter) so I apologize if this is in the wrong section . But recently I've been having a problem with my S3 mini and hoped I could get some help on here. So a few days ago I got a 4000mAh - 3.7V extended battery for my phone because my old one had broken. The old battery was the stock battery that came with the phone. Before I bought the new battery I also installed the PacmanROM on my android. But since I got the battery the percentage my android displays has been completely wrong. I'm pretty sure that the battery is fully charged after over 16 hours of charging but the percentage the phone displays is only around 65% and no matter how long I charge it the percentage never reaches 100 and it will stay on a certain value that will randomly fluctuate if I restart the device. So is there anyway to make my phone display the correct percentage? Thanks for your help!
In my opinion, extended batteries are more trouble than they're worth. I have dabbled with them but all have failed at some point (even brand new). If you put the battery on a flat surface and it 'wobbles' at all then its duff. I use stock batteries. Sorry if this is not what you want as an answer but just my experience with extended batteries.

Thanks for the input anyway! I've never tried any other extended batteries so I ignorantly decided to get one hoping it would work well. But anyways I believe that its not the battery that's at fault since the battery seems fine to me (no bumps showing a faulty battery). I have a feeling that its my old battery that's at fault or the system still possibly assuming its a stock battery. Well I'm no expert .
Awfully I can post the link for fix this..
The APP for fix this 'bug' is "Battery Calibration", it delets a battery file, and after restart the cellphone, that file is remade with correct data.
Well I looked into Battery Calibration and have managed to find a fix! I charged my phone to "full" (which my phone only displayed as ~50% at the time) and once the battery percentage stopped increasing I left the phone to charge for a few hours after that. Then when I was sure that the battery is actually full, I installed a battery calibration app and "calibrated" my battery which deleted the batterystats.bin file. I then waited for my phone to completely run out of charge, which I sped up with an app called "battery discharge", then when I let the phone switch off by itself from an empty battery. Once the phone restarted the battery percentage displayed was correct.
Try Battery calibration
isnt battery callibration a complete myth and placebo? deleting batterystats.bin shouldnt help as it just contains data about what consumed battery juice
