So I'm running cm9, on a custom kernel to improve battery life, my phone crashes and would not unlock, so I took the battery out and turned back on, to find I've lost about 80% battery?! Restart again, 1%, and same thing. So now I'm running on 1% and I'm not sure where I should just charge it up again

Re: [ROM][GT-P31XX][JB][4.1.2] CyanogenMod 10 official nightly builds
Hi
I got a very extrange battery behaviour.
At some point in the day, the battery start to decrease very fast, the tablet is in standby and it is cold. When I switch on the tablet I discover that left 2% of battery. The first time I switch off the tablet, and later I switch it on and discover that I have 60% of battery.
The second day I got the same problem..... The battery goes up and down constantly between charges... Yes, i don't charge it however the battery increase the % and then goes down again. I can use the tablet with the issue but never know how much battery really left until it goes off.
I can't find this issue in the forum... I am the only one?

Hi, my phone battery keeps messing up. I have done a battery calibration but it still seems to mess up.
The main problem is that the battery runs out, 10 mins later I have like 3 percent battery, then that runs out so I start to charge it, it charges up to around 20 percent then it jumps to around 60 percent.
By the way I have terrible battery life too - maybe 1 to 2 hours of use before running out.
Edit - I didn't say this but I am on albinoman887's cm10.1 rom.

I'm facing a similar issue, and changing Kernels doesn't seem to help either.
Things have gotten slightly better now in today's build. If updating doesn't help then you should try staying in an older build, the last where the issue was not present.
I don't think its the ROM's issue. Even by itself, after reboot I gain a few % of battery but those deplete quickly.
And then while charging. I restart, from 20% to 60% is possible too. So its not recommended restarting while charging.
Full charge then calculate drain pattern.
I have similar problems. My phone also shuts down very often. When I turn it on again it shows strange readings like 0%, 11% etc. If I reboot my phone it might either stick with the percentage it showed before, not boot at all, or jump back to 80% or so. However, it never takes long before it shuts down again. Even happens sometimes when using my charger...
Chances of my phone shutting down instantly are nearly at a 100% when using the flash while taking a picture.
I don't know what to think in terms of whether or not this is a software or hardware issue as many other people have similar problems, all on different roms and kernels.
Currently I am on:
Firmware build: 3.33
Kernel: Sultan Kernel r21
Rom: JBMIUIv4.1 #3.3.1
about battery percentange when chraging it's a commonn htc issue
i have the same too
no one has found a solution for it yet
Do you all get bad battery life too? Because I don't seem to get a very long battery life.

No. The battery life on Albino's builds has been nothing short of fantastic for most. You might consider replacing your battery if it's the original stock one. It's bound to be wearing out by now.
I have just bought an anker battery so I will see how it fairs vs he original battery.

I believe its something that occasionally happens when u change a rom and kernel. I remember theres somewhere where u can reset battery stats....i think in clockwork...

In fact, kernel and ROM do affect battery life, search for what fits your cell phone the best.
I get amazing battery life on ViperS 1.6.3 and the latest Faux + Yank555's kernel besides TurboBoost MOD... These can make up a great combination

I dont think they affected the rom so much as to ruin the battery or drain it faster. Charge the battery and reset stats 90% i bet it works.

I have had this problem through numerous roms so i have put it down to the phone and not the software.
R: Strange battery stats.
It can happen at any point if u ever flashed a not-so-secure or old rom.
Once the battery percentages, for any reason, get corrupted, theyre gonna stick to being corrupted no matter how many flashes u try.
Really its not that difficult u just have to press a button (i believe, as i said, in clockwork but im not sure) and all that will happen is when phone reboots battery will get reanalyzed and resynced, nothing else gets modified. might save ur day.

You are describing 'battery calibration'. Its complete urban legend hogwash. It does absolutely nothing.
Wiping the battery stats has no effect whatsoever on battery performance. Those stats get wiped every time you charge the phone to 100%.
However, you can improve the battery reporting by charging to 100%, then draining all the way to 0%, then charging all the way back to 100% again without rebooting (other than after it shuts off at 0%). This is not calibration. Its just running the battery through a full charge and discharge cycle. This helps to stabilize how the draining is reported. It does nothing to actually make the battery last longer.

Then please explain how I can drain my battery to 0% if my phone shuts off every minute. As long as I keep the charger plugged in, my phone will function like it should. However, as soon as the charger gets disconnected, it's only a matter of minutes before the screen goes blank and my phone shuts itself off without notice. Then when I reboot, chances are that either 1) it won't even boot and shut itself down at the splash screen 2) it's gonna give me a strange battery reading and shut itself off again after 10 seconds of activity. So how am I supposed to drain my battery if I can't even get it to drain, because it constantly shuts itself off?

The stock battery that comes with the Sensation is known to have this problem. I experienced this problem quite often before I was rooted; a new 1900mAh battery remedied the issue. Here is proof that this isn't software related: after becoming extremely frustrated with the lags and random reboots of my recently ICS-updated Sensation, I decided to do a factory reset. The phone restarted normally with all data wiped and everything seemed like normal again. So I was just sitting there happily with my phone at 50% battery. I decided to open the browser to go and browse the web, and the phone was quite goo- BOOM! RANDOM REBOOT! After my phone finished rebooting, it was at 4% battery!
Moral of the story: HTC doesn't know how to make batteries. Buy a third party battery like Anker.

battery life varies from phone to phone, kernel to kernel and rom to rom. but your battery behavior sounds exceptional.
Like stated previously, wiping battery stats in recovery (Battery Calibaration does exactly the same on rooted phones) has never proved me to be efficient. Random shutdowns occur when the phone isn't recieving enough juice from the battery, the demand in voltage will exceed the CPU's capacity and the phone shuts down to prevent damage.
here's something you can try and it worked for me. I used to have random shutdowns and poor battery life aswell.
Wedge a piece of paper, like 0,5-1mm thick, between the upper right corner of your battery, and the battery housing. This way the battery will be presses firmly against the 4 contact pins. Also make sure the contacts are clean.
maybe it's just a battery issue. What does the battery info section say about the condition of the battery?
My anker battery arrived 2 to 3 days ago and it seems to have stopped all problems with the battery.
Thanks for all the suggestions though. I will refer back to this thread if any other problems arise.
Hi..
I know this is a known bug in jb leak 1, but is there a fix for the sudden drop in battery level?
Daily as soon as the battery level reaches 30, there's a drop of 10%.
I already tried clearing battery stats from recovery but still no luck..

Like you said, it's a known bug. Even the custom 4.1.2 ROMs like MagicMod and CM10 have a similar issue. With those two the battery reading will go from 19% to 1% really quick but stay at 1% for over an hour sometimes. It's not a problem with the battery, it's just the way those ROMs report the battery reading (that's part of the reason why clearing battery stats doesn't help). AFAIK there was never a fix for that.

Happens with me too using dirty unicorn with jbx. As soon as I get to around 30% it just drops to 19

There is no solution for that I'm afraid as the same thing happens on custom roms and stock with the 1% battery feature. It's been happening for a long time so it's nothing new.

i am also facing same battery problems but mine is also some different, when my battery is at 20-30% and if i plugged charger(samsung's charger or Data Cable) then within 25-30 minute it become 90-100%. once i have reverse problem while connected to laptop for full day its charged max 70%.

Samsung chargers I believe have more voltage supplied during charging. That's why it charges up quickly. While laptop doesn't give out that much of voltage.
I once have battery drop but only around 5%.. 24%-19%.. but now it seems fine.. I use leak 3 as daily drive.. I think it depends on charge cycle.. if u charged a lot and your phone are used to the pattern then your battery cycle won't be messy with sudden drop..

Hi.
If I am on KitKat, and my battery level goes below 20%, my phone switches off and I cannot start it unless I charge it a little.
The same happens on lollipop but instead of below 20% it's shuts down as soon as the battery hits 10%.
Is there something wrong with the battery stats? How do I fix it? Or is something wrong with the battery itself?

My One shuts down when it reached 0% battery.

But normally it shouldn't shut down at 20%...

A simple calliberation solved the issue. Thanks a lot everyone! Cheers
