I don't know if it's the ROM itself, the battery or any other problem but every time my phone dies & I put it on the charge for a couple of minutes, I turn it back on & the battery level jumps up about 30%. What should I do about this?
i.e. I'm not running on the stock ROM.
It might have to do with the Sensation's issue with reporting battery levels accurately--sort of like how your phone stays at 100% for several hours before finally dropping down.
Is it a stock battery or large capicity version, if the larger version there is an issue with some roms or phones recognising the battery correctly
It's the stock battery that came with the phone...do I have to calibrate the battery?
One thing you could try is charging the battery to 100%, then booting into clockworkmod recovery, go to advanced, and click wipe battery stats. Then once the phone boots just unplug it and let it drain from normal use, and charge it to a hundred another 2-3 times and that should get the battery back on track. I did this after changing roms and it worked for me
may some of the wipe battery options can help you

Hey guys, is anyone else here experiencing the battery level going up when you restart the phone?
If my battery is at 70%, and I restart it, it'll be at 76% or even higher and remain that way for quite a while (remains a consistantly drain, not a single major drain in a short period of time)
This is something that's been happening since I was stock (Retail device from T-mobile store on launch date)
Here's some info:
-S-OFF using Revolutionary, and then later upgraded to 4.0.0.9 via terminal emulator
-Rooted stock (no rom uploaded)
-1900 mha Anker battery
-Battery stats wiped
-UncleSpoon's battery icon mod
even after all that, it'll still do it. So is it just me, or is everyone else experiencing this?
Yes, you have to re-calibrate your battery stats.
No, the CWM menu option to wipe battery stats is not right, for some reason.
Go get this free app: Battery Calibration
Charge your battery all the way up and let it sit charging for a few minutes after you see the light turn green (while turned on and booted up)
After it's been green for a few minutes, open this app and click the big "calibrate" button, and then un-plug it from the charger.
Let it run down until it turns itself off, without plugging it in. This means no usb to the computer, either - and don't turn it off manually.
After it turns itself off from lack of juice, plug it in (wait about 30 seconds) and then turn it back on. If you turn it on too quickly weird things may happen, depends on how depleted the battery is. (usually there is 1 or 2 % left so it's ok)
Leave it plugged in and turned on until fully charged. After that, you can feel free to play with it, but you should run it up and down a few more times without charging in-between. The first one is critical to do this way, though, or you are just wasting your time.
You MUST be rooted, or it will not work. (said for others who may need this info)
Tip to drain battery - screen brightness all the way up, screen to not turn off, and turn the flashlight app on. Leave it sit for a few hours.
Tip to charge quickly while on: Turn all wireless and data communication off, tap power button to turn screen off (keeping phone on)
Good luck, it'll solve the problem though.
I used battery calibration to wipe my battery stats (I did it in recovery on my 3G Slide, so I'm aware of that alternative method)..
I've let my stock battery get to 0% but that was pre-root.
After reading all the charging problems with the CWM, I was a bit afraid to attempt the 0% drain on the new Anker.
Are you running 4.0.0.9, and does it charge fine? I'd hate to deplete an Anker since I have no external battery charger.

Removing the stats only doesn't calibrate the battery, check the calibration guide in my sig, for a correct method that works for any android device.

Seriously, that's a good read.
I agree.
What I recommended was better then just wiping battery stats with CWM, but nowhere near as good as what Ace42 linked us up to.
I'd recommend reading those threads and doing that instead, I am more then happy to be corrected and shown a better way.
(FYI - I depleted a stock battery completely, both in CWM 4.0.0.8 and 4.0.0.9 to test the charging issue. You will always be able to charge it in the phone, even if you bring it completely to dead.
The idea that you can't is a myth, and was a concern until it was proven not to be true.)
Hi
I have tried to get the battery to calibrate to 100% using the Battery Calibration 1.3 Nexus app.
I have thalamus 2.6.35.14 r2 kernel installed on my phone which is a requirement of the Calibration app.
I have done tried it twice and successful got it to achieve learning mode but it did fully charge, but the battery age was only reading to 94% when I restarted it in the app. I wanted to try it once more and power off instead of restarting it, but Learning mode will not activate any more.
Learning mode gets activated when the battery drains to 3201mV, but mine won't activate, it goes to 3190mV and my phone shuts down. I have tried to reset the battery stats, wipe delvik cache. I did a have modded ver of the kernel 2.6.35.14, so I installed the above kernel but no joy.
Does any one have any ideas? I am quite frustrated... Tried it about 5 times tonight to activate learning mode, but no joy....
I doubt there is need for a "battery calibration app".
Just charge it full and delete /data/system/batterystats.bin
and on next restart it will relearn and calibrate on the battery.
I have done that before, and delete the battery stats, every time I install a new kernel. Phone shutdowns at 8%. I want the phone to shutdown at 0-1%
I read somewhere that the 95% full charge on the Samsung Nexus is intentional. Li-ion batteries don't like to be charged at 100% and drained near 1%. The battery is kept at its optimum charging capacity at 95%.
I don't use battery calibrators

You can't calibrate it perfectly.
No two batteries are the same.
If the voltage suddenly drops below a certain level the phone shuts done, even if it is only at 8%.
It is possible that with repeated use the display will get more accurate.
Ever since I have flashed 4ext recovery My battery jumps percentages. For example: If i charge my phone from ~30% overnight with the device switched on, as soon as I unplug my phone it's fine, but after about 15 minutes the battery plummets to about 90% without me even using it! Second thing, if I decide to reboot into recovery to flash a theme or mod or whatever the percentage when in recovery mode shows that it is higher than what is indicated when fully turned on?? And once again, if i reboot from there, when the device has turned on the battery has plummeted even further to 50%! Yes I've deleted batterystats.bin and calibrated the battery, and yet still this happens!
I experienced a very similar issue with my last phone (HTC Desire) and that was linked to it being "USB bricked" and was able to resolve my problem.
Thank you all in advance

Wel with my experience (do you have a percentage mod installed?) uot kitchen mods react weird with my device. The battery isn't necessarily draining. The mod isn't representing the actual percentage.
My work.around was as follows
Drain to 2 percent
Turn phone off and charge over night
(this way the battery decides when its full)
Deal with percentage reading being way off for a whole day. When it dies turn it back on and there will be the residual percentage that was skipped over. Let that drain down. Then try and turn it back on (repeat steps)
After phone dies completely then charge once again overnight with phone Off.
Wake up unplug phone, boot into recovery, plug phone back in, wipe dalvik/cache then bat stats. Reboot and unplug.
That's what I do. Sounds like a lot but you get a routine after a while. Ya a lot if people percentage mods do that to me.
Hope this helped
Good luck
I'm mobile right now
I have the same problem with one diference, when battery jump - phone turn off
Hi all,
There's this problem with my phone that everytime I charge it, it takes an elongated time to do so. This issue first emerged when I was on stock GB after a minor OTA update which added the power saver toggle to the quick settings menu..The problem is that it takes about 4-5 hours to fully charge the phone, and if I rebooted in the middle of charging when it's about 70% or 80%, it suddenly shows that the phone is fully charged, and the indicator becomes green! But afterwards the battery drains as quickly!
Now I have S-Off and using ARHD 6.6.3 ROM, but it seems the problem persists ..I wiped battery stats as soon as I flashed the ROM as well..Although it's not a problem I cannot live with, it's annoying enough when it happens.
Can someone please help me? And suggest me what to do?

its common thing...the battery calibration is not proper that's all...
also you need to wipe stats once you charge your phone to 100%
then battery will try to calibrate ...and after 3-4 full complete cycles (100-0 and 0-100)
the battery will settle..
the battery drain will be there ...whenever you flash a rom or flash a kernel....battery only settles atleast after 2 full cycles
EDIT: also download currentwidget from market..as the name says its a widget..so you will see it in widgets once you installed it...this will give you more proper reading of battery...when you plug your phone to charge...and when current widget reads 0mah then your battery is charged completely...(it might take a long time to read 0mah...but charge it until you see 0mah)..then wipe the battery stats...so after this battery calibration will be proper
Also the sudden jump of battery percentage is due to improper battery calibration
so dont worry you got no problem
So
I read somewhere that you are not supposed to let the phone go to zero because it could cause your phone to not power back on anymore..is this fact. I couldn't find where I read it to back and read again. Mine has been doing some weird things as well...the led turns green before it is 100% and it goes from 100% and drops to like 89% out of no where.

when i meant 100%-0% means until your phone turns off due to less power..it might not(or won't be) be 0% then
as i told you that kind of jumps are common ...in my case it went to 60% to 100% when i rebooted ...also the dropping used to be in large scale too

Thanks mate! I will try this out! cheers!
My Moto Maxx is never going below 15% battery for quite some time.
I was running CM 12.1 before and I am running the CM 13.0 preview now.
The problem now seems much worse.
This could be my battery dying?
Wait its not going below 15% or above 15%? Also, did you flash the ROM with a clean wipe (no dirty flash)?
Another thing to note is that the CM 13.0 Build is a "PREVIEW" which means that there are a TON of bugs in there. I would advise you go back to CM 12.1 for the time being.
It is never going below 15%.
On CM12.1 it also happened.
When it reaches 15% percent, the phone shuts down and needs to be charged.
After sometime charging, it displays the battery as above 15% and I can turn it on again.
Mine had always done that at 5 percent. Here lately it's closer to 7 percent.
I'm on original 5.0.2 and also facing that issue... I've heard onde it's related to the use of non original chargers, or even QI chargers... Never got rid of it, even after a full wipe/factory reset...
I've had this problem too and made a post over in the Droid Turbo forums but no one ever replied..
At least I'm not the only one that has this problem.
Yeah I've always had this issue between 5-8% on my three Turbos. Stock Rom and other flavors. They all shut the phone down around there.
Solved the problem with this app: https://play.google.com/store/apps/details?id=com.newagetools.batdoc&hl=pt_BR
Now my battery goes down to 1% again, yahoo!!!!
how can that app fix it?? i would think its a placebo effect as i see dificult for an app to read or fix battery info...
maybe it locks out the bad parts (like an old chkdsk on a HD)
anyway i will tryit if i see it tries to go rogue with the Ads it Dies..
Batteries in laptops and phones have a file that keeps track of battery life. They use this to estimate percentage.
Sent from my DROID Turbo using XDA-Developers mobile app
still having this issue
I have the same problem. It started as shutting down at %5, then %7, now it's %15 shuts down.
The same thing on my XT1254. It shuts down near 5%, I will try to charge it with my old i9505 charger, it could be a problem related to TurboCharger.
Hello guys,
My girlfriend's phone had this issue some months ago, what I did in order to fix this issue was:
1) Let the battery drain until phone shutdown. (try to turn on again until you cannot)
2) Fully charge with an original Motorola charger (phone turned off)
3) When it reached 100%, turn on the phone but enter in the fastboot mode and wipe caches
4) Uses the phone normally and let reaches 0%.
Making these steps, the battery back to have a "normal" behaviour

I´ll perform these steps, thank you
Although you see the battery as percentage, the operating system does not see it that way. It uses lower limit voltage of the battery to shut down the device in order to extend battery life. Batteries do not like to get and stay deep discharged (below low level voltage)...if you do this frequently, you will severely hamper your battery's life.
