Battery issue, 17% then off

That's strange, my battery is inaccurate. When it arrives ate 17% it dies, when I start charging again it starts at 1%, then when arrive at 80% it appears at 100%
Something is really wrong, I dunno why.
I already tried wiping the battery stats (on recovery), but still the same thing.
Any help? Any app to fix it?
Thanks.

Try this, need root:

The battery seems physically dead. Calibration is bullcrap anyway, it proceeds automatically once you reach 100% battery.

My phone is buging. Can you help me? Thank pro.

Thanks for the help guys. Going to see if it fix

You fixed it?

Purchase a new battery and test again.
That has worked for me.

It's the idea, going to do that, thanks

Perhaps you will give this one a try?

Maybe try wiping battery stats in cwm recovery and reflash the rom ur using I had this issue but mine used to die out at 7% or so after I did that haven't seen battery issues since then I'm on miui rom might work for u too. I think it happens if you flash new roms a lot at that time I was experimenting with all kinds of roms then stuck around with miui since I believe its the best

Battery problem

Hi Folks, I hve had my note for 1 year now and haven't had any battery problems until 2 days ago when I flashed a jb rom. All was fine for about 10 hours when I started to recharge the battery again that went fine, charged to 100% and unplugged, the phone said it was at 100%. After another few hours the phone cut out, no warning just cut out. I could get the phone back on but only when plugged into the charger. So, heres my problem, phone says battery is fully charged but when I unplug the charger it cuts out now. if I boot in to recovery with out the charger it stays on for hours. if I try to start the phone up normally with out charger it doesn't work. I have tried another battery again it started fine for almost a day then the same problems again. I have tried several kernels and roms in case it was one of those that was causing the problem but its the same every time. Im not a newb when it comes to flashing roms some im 100% sure its all ok in that department. any help would be appreciated.
thanks
Graham

My note is also about 10 months old. I want to know if my battery stats. I feel like my phone is giving me short time.
My question is do i need a replacement with these stats????

What really matters here is your screen on time (I can get around 4h30 with heavy use). I also see you have a few notifications so there might be some draining apps running in the background (like that *** Facebook app which is constantly running in the background even with notifications off). In any case BBS should help you identify the "rogue" app (if any). Also I don't use Google Now as it's kind of a battery killer.

this problem is same with me...after 1 year use gnote
and this is battery problem..i dont know whats is causing it...
i try to enter recovery mode and ..battery is good..almost 4 hours screen on recovery mode
but if I try to start the phone up normally phone is reboot after 1minute in homescreen android
trying with different rom jb ..same problem ..
after replace my battery ..problem is gone..

@strachg If the phone used to work well before you flashed JB I'd recommend going back to ICS to see if the problem persists. If it disappears the reason is JB which would not supprise me since all JB roms for the Note are not really bug free. If the phone continues to behave like you described and changing the battery does not help either I'd say it's a hardware failure.

Hi, Yeah I already tried going back to ics and it was just the same, it just seems like a bit of coincidence and really annoying lol. The only thing I can think off that is causing it is as you say that its a hardware fault and it must be overcharging the battery and breaking it. If it was JB that was causing it im sure I wouldn't have been the only one by now.
thanks
Graham

how did you install jb? Was it clean on safe kernel? You havent eliminated the possibility of software issues.
Qazibazit, it looks ok.
Guideline 3,5-4,5 hours on screen time is normal (if you play games can be less, thus is from full to 1%). Total standby time, usually more then 24 hours is normal.
If you have a lot less, go read ahalfords sticky on wakelocks. All you need to know to optimize battery.

Hi baz 77 yeah using safe kernel, tried a few actually. And using utackas. Version of paranoid android now again tried a few Roms. Everything was wiped and redone the process about 20 times. I looked through all the roms. And kernel threads and no one has had this problem. New battery coming so will see how it goes now.

yep thats pretty definitive, at least if all those roms are not having same base and thus posibly same issues.
Your new battery will improve your experience quite a bit if its a good one!
Have fun with it and let us know if it worked for you

[Q] Battery Wipe

Hey all,
I've recently switched to a Sony Xperia T (LT30a) on the Rogers network here in Canada.
I want to do a battery wipe at some point but I can't get into the boot loader when starting up the phone.
I've tried every combination I've seen on here including.
Power On + Vol Up
Power On + at sony screen + Vol Up Repetitively (Same with Down)
Power On + Volume Down
I remember it being a lot easier on my old Samsung Galaxy S2 and other android phones.
Any advice?
Many thanks!
Basttrax

You have to unlock the bootloader to be able to "get into it“
Which I don't think you can not do on your phone.
However, what I think you mean is the recovery, which Xperia phones do not come with, you must root it and install cmw recovery for locked bootloaders, find it in the dev section

Damn. Yes I do mean recovery. Is there any way to do a battery stat wipe outside of recovery? My phone seems to go dead with around 10% left on the display.

If you are rooted you can just delete the file.
I am trying to remember where it is located...if anyone else can help out please chime in

Tapped from The Bond Phone!

Wow gotta love XDA and the great users on here. I'll give it a try tonight.
I read that I was supposed to drain the phone completely. Charge full without turning on then boot into recovery and wipe battery stats. When in this process should I delete the stats?
Thanks again

after the full charge will be the same as the process you just said.

Wiping battery stats means deleting the file.
But besides, you should try this app. It might help you save some time:

If that's the case why does the phone totally die before getting below 14% battery?

A lot of people seem to have this issue, so I assume it's a flaw in the Rom, you could try a different version.
But first I would wipe cache and dalvik and fix permissions from recovery, then download Rom manager and run fix permissions from there, twice before rebooting, this does the data partition the one from recovery does the system partition only.
Bet that improves the situation, then completely drain the phone so that it won't power on just the three flashes of red light, then charge to full with no interruptions until the phone reports battery full

[Q] Ridiculous Battery Drain

Dear People of XDA,
I have this issue since a few days and I don't know how to solve it. My battery drains out after 10 min while using wifi and the phone will shut down of course. Leaving it for about an hours time, some power will be regained and I can continue using my device. It all started when I reverted back to stock ICS from cm 10.1. I thought flashing Carburano's ROM might help but apparently not, same problem. I know batterys don't always go nuts but when they do, it's progressive. Any one know what might be wrong?
Regards....

Use the better battery stats app and check which app running in the background is draining your battery without allowing the device going into sleep....
but if the drain is like what you have described....then it is time to move on to another battery....
just a word.....Kernel is something (other things being Baseband) which takes care of the battery performance....so maybe you can try changing this and check which one suits you well.
CHECK IN THE FORUM TO FIND INFO ABOUT APPS LIKE GREENIFY...
Hope this helps you

Thinking it like this: the phone probably can drain a fully charged battery in 10 minutes if you turn on every major component, like vibration, flash, display to 100%, gps, wifi, 3G and what else... But having just wifi on and getting a phone shutdown in 10 min seems excessive. This would suggest your battery is not charging properly. This can result from end-of-lifetime battery only charging to some 10-25% of original capacity, broken charger, battery self-discharge and probably some other reasons I could not think of right now.
The best solution, most likely, is to replace your battery (like SREEPRAJAY above already suggested), but if you like to troubleshoot you could try to charge your phone via USB to reduce the charging current (Li-ion batteries show a lower voltage during charging with lower charge current until 100% is reached). This way you may be able to charge to higher capacity. Also, it may hint that some kernel might work better for you, but I'm not sure about this, since I don't remember what part of Android (SW, charger HW or what) handles the charging logic, i.e. what triggers the charging actually to stop.

Thanks...I'll try the suggestions

well maybe your battery isn't so good anymore or you must try also other roms like jelly cream and those kind of roms and if you wanna know the rom slimbean and cm10.2 from tonyp are also pretty smooth and battery saving but cm10.2 is sadly not working camera still but further it's damm good

Hi I have experienced some issues with battery draining, when I check battery stats it says that most of the battery is drained from Android . media. Service... I have no idea how to work out or disable whatsoever is using those services.. Btw I'm on cm10.1 latest nightly

He didn't say BUY a NEW battery. He said TRY an ALTERNATIVE battery.

How often does it switch off? If it's often then you could try leaving it in recovery mode to see if it does it there...

Recovery mode does not use much resources. So it will be hard to tell.

I have a 2 month old original battery in my note. I noticed screen flickering a week ago which is a sure sign the battery is past its prime.
Still, some questions:
Have you dropped this phone?
Are you still running stock android? root?
Did you overclock / undervolt anything?
How often is this happening?
Is the phone hot when this happens?

Ofcourse,I've dropped it many times.I think problem also because of that droppings only.Running on stock firmware.No overclock.Can't say how often....The phone won't be hot but may be sometimes I feel slight hotter.

There is no guarantee that a custom rom can help, but it is much easier than dealing with hardware issue. Definitely should try a custom rom 4.12 to see if it helps.

Custom rom also not helping.Today it switched off completely and not switching on even.sometimes it switches on after sometime but no luck this time.so please someone suggest me,what are my options now ?and What would I do now ?

Personally, my next step would be opening it up, remove all the dust(if any) and check all connections.
If that does not help, you have a problem.
If all fails, consider maybe overvolting and/or underclocking.?
