[Q]Battery Death?

Im running the latest MIUI. How come my battery is draining so fast? and Cell Standby is using all the battery power. Any tips?

When I was on miui was actually when I had the best battery life. Not sure what to tell you. Did you follow the install instructions in the miui thead?
Sent via the power of a unicorn's horn.

The weird thing Is I had awesome battery till my friend used some "battery calibration" app.. Now its a no go for me.. what should I do?

I recommend you wipe and reflash the rom. Clear dalvik and bat stats.

[Q] Battery Calibration

I have a question about battery calibration.
After I deleted batterystats.bin, the meter seems to be working fine (prior to deletion, battery meter was not correct - for example, only 50% battery was remaining, but battery meter would be around 70%.
Anyway, do I have to calibrate battery each time I flash new/upgrade ROM?
I've been changing to different ROMs frequently nowadays to find best battery ROM. So I was wondering if I have to calibrate battery each time I flash new ROM.
Thank you!

Honestly I dont think it matters much. I've heard arguments both ways but what I do is I calibrate when I first get me phone (or a new battery) and thats it. I get great battery like even going between roms

You MUST delete the battery stats.bin everytime you flash a new rom

I don't agree with the word must. It would be a good thing after a few flashes but EVERY time is not needed.

Um.. no. theres a proper way to caliberate the battery.
If that was the case then I'd be wiping my battery stats everyday because of CM7 nightlies
But yeah, I'd probably say just do it if you feel that your battery life is awful. Maybe once every 3-5 months? I've had the NS since it first came out and I haven't wiped my battery stats. Battery life is still amazing, so I don't know.

[Tutorial]Battery Recalibration

Though Most of you Might know this already But I'll post it for the new Users out there
So you have flashed your Rom Recently and are finding some trouble with your battery?
Does it dies too quickly? or you see those numbers going down very Soon?
There might be some Other Issues related to Battery drainage but most common problem the user might experience after flashing quite a few ROM's is Mis- callibration of the battery
To fix this install a market app known as battery callibration
https://market.android.com/details?id=com.nema.batterycalibration&feature=search_result#?t=W251bGwsMSwxLDEsImNvbS5uZW1hLmJhdHRlcnljYWxpYnJhdGlvbiJd
You need to have a ROOTED device for that
program does it by removing the batterystats.bin system file. The OS generates a new clean batterystats file soon, thus any fake information from the previous ROM is removed.
When you reboot the phone after calibration a new batterystats.bin is created
IMPORTANT after calibration let your phone discharge to 0% and then charge it to 100% without break
DO IT AT YOUR OWN RISK (although None is involved) I'm NOT RESPONSIBLE FOR
ANY SORT OF DAMAGE DONE.
Hope this helps you guys

This can also be done via CWM usinge the delete battery stats option.

Sure But as stated this is for new users Who are not well acquainted with recovery

Just following logic. If someone has started flashing Roms and rooting devices, I would be surprised if they had not discovered CWM

after doing research on all methods to recallibrate checking pros and cons finally i got the answer brothers...its very simple no need for cwm or drain full abttery kill your batery download recallibrate delete batterystat.bin....all fake bother....just do a simple step remove your battery for 2-5 minutes and than on it....you are recalibrated....simple

but what about batterystats.bin? Why is it there? ^^
And from which research resource you are talking?

Hey..it works,thanks for your efort in researching this
I'm quite desperate coz ever since I'm installing creed 1.7 seems like my bettery drain very fast,too bad coz I like this ROM. Last night I charged it to 100%,then I go to sleep(so my HH is idle) but when I woke up 3 hours later,my battery stat already drop to 84%,strange. So I try plugged out my battery for 5 mins and voila..now it's written 53% but it's been like that for half hour so maybe it's quite stable now. Thanks again dude

since 13 months i m using fit bro and the most annoying thing of android was battery backup so researched almost all sites of android and lion baterry ....checked alll methods of battery boosting from apps and ram clearance,...the battery stats.bin bro yup that you dont have to take care its android system which adjust itself and recalibrate when you make your android without power means no battery for a while and when you insert it again the system itself recognizes....killing your battery specialy lion reduces its self life also its the number of cycles so whenever you charge charge your phone to fullest not like every 5 min you are charging your phone once a day to the fullest just check what i said bro its really works just believe and c

However, as she explains, that’s not the case. Because those battery stats, stored in the batterystats.bin file, are only used to maintain information about what is using the battery when not recharging. That is, it essentially holds the information displayed in the Settings > Battery screen. Nothing more, nothing less. Thus:
It has no impact on the current battery level shown to you.
It has no impact on your battery life.

I did battery re calibration once and it made no difference at all, having a google engineer dis-miss all the myths is good enough for me buddy.

Yeah I agree too..Not much difference
but still not that difficult too (Matter of seconds?)

I installed Battery Calibration 1.2. When open it writes the following:
1. Plug in your phone to the charger
2. Wait till it charges to 100%
3. Click 'Battery Calibration'
4. Unplug your phone

Thanks for this! I heard from some android users that Battery Calibration is a myth, but it appears to be really effective anyway.

This work for me. Don't wipe battery. After install ROM, remove battery about 5 minutes and it is well.

Sent from my HTC Explorer A310e using xda premium

+1 for the similar problem.... Kindly help me too.... I was about to post this question and i saw your post... Devs plz help us...
Heavy battery discharge + unable to charge battery till 100%, stuck at 83%... Done everything possible.. Using FlyROM v2 Kernel 3.0..

vishuhtc- You can try installing "better battery stats"(check out xda), or "GSam battery monitor", you will see what is killing it, if you don't get your answer with this apps check this thread http://forum.xda-developers.com/showthread.php?t=2093542 . Also if you are using super wipe, to flash roms, try flashing without it, or with it, but manually delete bootloader data, cos it doesn't do it automatikly
khanjan2khan- check out with the second app what voltage gets to your battery, it should be something like 4.000V or a little bit more, if it goes to that, you should also calibrate it or just delete battery stats from recovery, if it doesn't get to that............. try with another charger, or with a service center.

Misterious Battery Drain

Hello guys,
These days I've been noticing that something is draining my battery really fast. I checked and only half of the time my device is ON it is in deep sleep. The other half is on 400Mhz frequency. I check battery stats on Settings and OS is consuming it all. Yesterday I didn't use it and I got 1h of screen, and 25 minutes the day before. And again 50% of the time in sleep mode and 50% used (but I didn't use it)
Something is not letting my phone go into sleep mode. It's been happening for a week now.
Any clues on how to check deeper what's causing it?

i dont know whats causing it but i had it to in the night it lost 5/6 % of battery and i started to hate it but i installed greenify 3.0 build 5 and donate version so i added every single app and some system apps in it and it helped me allot only 1% lost in the night about 9 ours so its perfect for me now just try it i hope it helps

Loosing 6% in the night is not a problem. Actually, I turn on plane mode and I never loose any percentage in the night. My problem is that I loose all my battery percentage

did you try soft reset sometimes it helps calibrate battery?
hold volume down and power button wait tiill it reboots
and maybe its a app that you installed as last is waking up your device ?
and have tried a factory reset and what rom are you using ?

I have just tried what you said. I'll be testing it today.
However I calibrated my battery when this starting to make sure it was well calibrated.
And I thought I could be an app but it would be under Battery Settings and show us very consuming, wouldn't it?

yes that true it would show you but if i were you i did a factory reset fullwipe and use a good rom like alexis rom the latest one and install greenify aswell but first test what you are doing right now if its not good than you have no choice just full wipe clean install a good rom
First try this you can check it with this app also wakelock detector
