Yesterday, I let my battery die. Charged it last night, and wiped battery states. Ran the phone like normal today. Was down to about 30% left, rebooted. When everything came back up and running, that battery showed to be 5%. WTF!!! How do I drop 25%, just by rebooting?!?!?!?

So...I should wipe the battery stats again after re-charging to 100%?
Then wipe the battery stats in advanced of recovery mode

I re-wiped the battery stat this morning. I was down to about 50% when I needed to reboot. When everything came back up, it showed I was down to 28%. Is this an indication that the battery needs to be replaced or should I try a different Kernel?
Either you have a bad battery, bad battery meter, or your not reconditioning right.

What would you suggest I try? What is the proper way to recondition my battery?
Charge to 100%
Boot into recovery
Wipe battery stats
Reboot
Don't unplug charger until at desktop again (You could debate this one, but that's when I do it)
And don't worry about killing your battery, it'll do more harm than good.
Explanation - When you wipe battery stats, it tells your phone you're at 100%
So, if you wipe when you ARE at 100% you'll get accurate readings.

The past 2 times I did this, the phone was turned off and plugged in and charged over night. this morning I wiped the stat, but i do not remember if I had unplugged it before it finished booting up. I am charging it now, with it on. When it reaches 100%, should I reboot into recovery and wipe it or should I let it run all the way down?
What exactly do you mean by 'let it run all the way down'?

Down to say some were around 20 - 5%.
As far as I understand that shouldn't be necessary, and could weaken your battery.
As long as it's fully charged when you wipe the stats you should be good to go.

Ok...I have ran the phone like normal. Within 6 hours, I am down to 62%. I rebooted the phone, and it still shows me at 62%. At least I have that fixed.
Now, I see some people use OverStock and seem to be getting better battery life. I just want to get about 16+ hours out of my battery. Right now i seem to be pushing 12 hours. What is the tick that i am missing??
For every hundred vibrant users there seems to be a hundred different accounts of battery life, and a hindered different opinions on how to keep it down. 12 hours on the stock battery is pretty good, especially compared to stock.
Mine'll last me around 15+, if I left it not charging, i think.
I'm on overstock, the screen is at the dimmest 95% of the time, and I use setcpu. 1000/1000 with a screen off profile of 200/200. So, that works for me pretty well.

You need to recondition yr battery as posted above, 2-4 cycles. But i prefer to re-flash ROM when battery 100%, should you get proper batt stats.
You may buy new one to test yr system n batt stats, also good for spare. Or just borrow yr friends battery, just to check yr rom n batt stats. Treat it like you did before.
Good luck.

200/200 conservative scaling and no sleep death? Didn't know that was possible on overstock...guess I'll try it.
Edit: sleep of death...you must be on power save or something which afaik doesn't work at all.
*checks*
Yeah, powersave. What's this about it not working? It occasionally lags a little when I unlock it and the widget definitely says 200
Sent via telepathy
I don't think powersave is supported...try conservative and you'll get sleep death due to the low frequency...you don't get this with powersave because I don't believe it's working...trying to confirm this.
After I fully charge the phone, and disconnecting it from the power, the battery suddenly drops to 96-97%, it is normal? I already made a battery calibration past week. Even after I upgraded the phone from XXKG2 to XXKG6, still the same problem here. I bought the phone last month. (by the way, it is rooted and I have on it the 2.3.4 stock)
Post some pictures of the battery usage.
And also some of bestbatterystats.
Try this: After you get the "Fully Charged" notification, try not to take it off charging immediately. Leave it on there for about 10 minutes or so and then take it off of charging, you should see it as 100%. If this does not help. Please post some screenshots of your battery usage screen, we can troubleshoot from there.

Tap your finger on graph above and screenshot that.
Did you calibrate your battery, before or after you upgraded to KG6? If you calibrated it before, then you should try calibrating it again.
1. Charge 100% (best way switch your phone off)
2. Run Battery Calibration
3. Drain the battery until it's totally empty.
4. Charge again 100% (best way switch your phone off)
5. Reboot and enjoy

I think maybe batterystats.bin was not removed, I tried to remove it with Battery Calibration app, but I didn't checked if it was or not. Tommorow or on monday I will try to post some stats from Battery Monitor Widget
That does look very much like a non calibrated battery. Try calibrating it as 'Bruaca' mentioned, and you should be getting the correct readings this time around.

I did another calibration, with the device turned off until battery riches 100%, then I turned it on, then I removed the charger, and it was on 100%, I put the charger back, again after 5 minutes I heard the signal, then I went into Root Explorer and deleted the batterystats.bin, and pulled the charger, now I have 100% + 4143mV, it's normal? or should be more mV?
4143mV sounds a little high. Mine is ~3600. Though I'm getting the opposite problem. What might happen is that I'll leave it on overnight and it'll gain 2 or 3 percent of the battery. I started getting problems charging after I installed font changer, which was also weird. Like, it'll take ages to charge to 100%.
Edit: 4143mV sounds about right for a fully charged battery.
hello all
i have a question please
my battery is acting odd
if i charge my phone , and then unplug it ... it will still charge by itself a few points.
for example if i remove the charger at 80% and then leave the phone alone it will charge by itself in the next hour to about 84-85
if i charge to full ... it will show 96% ( which i know is normal ) and then charge to 100 by itself
it does not matter which precent i unplug the charger from it will still do this
i tried different kernels and roms , the problem still shows
using the default battery that came with the phone
any ideas please ?
thanks
easy fix, pull the battery without turning off the phone.
correct one, let the phone drain the battery till it shutdowns itself or until you have like 5%
i already tried to let it drain untill 1-5% and then charge it fully but the same thing happens
Have you tried replacing the battery? or it could be something in the rom that thinks its charging but i wont be! I used to have the same problem. I just flashed my original kernal from the insecure one i was using and it just fixed itself, but if youve already done that..
Have you had any other problems regarding the battery? for example a drop in battery life etc?
then pull the battery till it doesnt lower the fuel gauge if that doesnt works then replace the battery may be damaged as iGeoo said

ok let me explain while the device is turned on and in use you pull the battery and sometimes it will turn back on with a lower read of the fuel gauge (think of pulling the battery of a blackberry lol). after that it should start to give better readings.
also battery can be damaged by just heat and over-recharging it (leaving it connected for a long period of time after it reached its 100% of capacity)

You can always re-root after youve made it stock again. Cant help to try i suppose.

Hiya, that problem persists for few months. Before that everything was working fine and my battery could last for even 2 days! And soon, something happened... after that "something" my battery started to last for around 1 day :/
But here's another very annoying and strange thing. I usually turn my phone off. And, next day, when I turn my phone on, it has eated at least 20% of battery -_- So if I had 80% last night, I have 60% in morning. I had 4.1.2, now 4.2.2 android. I have wiped cache/data, resetted dalvik. Nothing changed, that problem still persists. Even if I bought new, additional battery :/
Install betterbatterystats, search on xda for it. It will monitor your wakelocks, read the OP of the thread on how to use it. Then, read in the betterbatterystats thread for solutions to your worst wakelocks.

Idk if it would help me... it still happens, when I have nothing installed on my phone. And, when I fully used my battery to 0% and charged it without turning phone on, it seems that 70% is "FULL battery" for the phone -_-
Tried a new battery? Borrow one from a friends s2 and see if the same thing happens. Could be the battery on the way out.

It was happening to my old, original battery, so I bought new one - still eats 20%.

But does it still only charge to 70%?
I am not sure with my 2nd battery, but gonna try to use it to 0% and charge. That original battery is surely ruined a bit.
Strangely, my phone sees 70% as full on my second battery as well :/
(and I was charging it while phone was off)
Hmm. I would guess hardware. But I know nothing about hardware sorry... @keithross39 any ideas on this one?

If your phone shows weird percentages, you might try to wipe the battery stats with cwm recovery (in the advanced section)..
Have you tried airplane mode at night? My device looses 4% then..
Good luck!
PS: My battery never lasts longer than one day. High usage and display brightness drain my battery mostly. I don't remember when it survived two days..
Try calibrating it, it sounds like a fuel gauge (plus a twist).
It could be your charger as well.
I don't think this is a hardware issue. Keith might tho.
Sent from...this is not even my S2
Airplane doesn't help much, my phone dies after 1 day even when I use it only to write few SMSes only :/ And I heard that wiping battery stats is a myth and doesn't help much. But, I had not that problem for some time, then it happened again and I don't know why.
How should I calibrate it, then?
Let it discharge till it goes off.
Charge it (while off) full.
Take your battery out for 90 sec.
Put it back.
Power on.
You' ve got nothing to lose.

Hii everyone
I've got some really weird Battery Issues on different Lollipop Roms (CM12, ResurrectionRemix 5.3.5-5.3.7, Beanstalk and SlimLP).
The problem is, as soon as i restart the phone the battery percentage drops from 50% to 13% for no reason.
If i charge the phone later suddendly the loose percentage are back, but the phone consumption more "battery" so it's sooner at 0% as normal.
Does anybody else faceing this problem? Or whats the solution?
(Tried several times to calibrate the battery, and it's a new one ca. 6 months old)

I've had these problems when I first bought my phone used off eBay. Phone battery was very erratic. After a reboot battery would be less than half or nearly 0 even with 80%+ battery. Or would shut down with 5% left. Or drain battery a lot quicker than normal.
Soon as I bought a new battery my problems vanished. My battery would stay solid no matter how many times I flashed a new ROM or rebooted. BUT after 3 months these drops have started to happen again with reboots. Not always like before, but they're happening.
I think it's down to battery conditioning. The way you charge and discharge your battery. There are set ways to charge a phone to maintain battery health.
How does your battery react without rebooting from a full change to shut down? You shouldn't need to reboot a phone with a good stable ROM once you've set it up the way you like it. Also calibrating you battery or wiping your fuel gauge meter to often isn't good practice as android and your phone will do calibrating itself after some time and needs the information that these starts provide.
Battery jumps seem to happen with a lot of S2 users. Maybe a flaw in the design of phone. But good battery practices are important, things like not leaving your phone charging overnight. Batteries don't like being left on charge when they are full. There's more info out there on XDA that I can't remember myself as I am guilty of bad battery practices as I use my phone all the time and don't have time to full charge cycle.
Yes same problem
Battery drains really fast when restarting
Any fix for this?
I am hiving battery problems too. Battery is dropping % like it leaking or sth. Last time my phone rebooted due to full ram and it dropped from 50% to 12%. I left it like that. After some time battery re-charged itself from 12 to 23 % ! Phone was lying on the sofa without connected charger ! Should i clen fuel guage chip or my battery is EOL ?

Forgot to say, if you want to avoid battery drops when rebooting make sure you plug your phone into charge before rebooting. Thus should stop battery dropping afterwards.

The battery often drops when the phone hangs at work and reboot from itself so i have no chance to plug it in.
I have same problem, battery drain too fast & after reboot same time battery level is "falling" at one moment twice. At first, I think it's a battery problem, but battery work fine at CM12 mod, and have problem at SLIMLP 5.1.1 mod. When battery "falling" it's not heating, which means no real discharge.
Hello friends I just purchased a new battery this is 3.7V battery
