[Q] How to calibrate battery

How to calibrate battery..?
I found application "Battery calibration" and it says:
Calibration needs to be done after flashing a new ROM, but you can calibrate any time you think your battery is miscalibrated. This 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.
It's suggested, but not necessary, to let the phone fully discharge after calibration, then charged to 100% without break.

But I didn't see any changes.. My battery stays around 13 hours...

After using "Battery calibration"and 2 times full battery charge, 72% yet (stock 2.3.3 KPE)

what was your usage?? i mean how much gaming, wifi, internet etc

Your display only eats 4% of your usage, i can say that your phone was mostly on standby when you posted this.

Yes only a few calls, and sms, but synchronization is on (2G only). Average battery life ~ 16h( 2.3.3 KPE), but better than villainrom 1.0 (max 7-8 h)

how is possible that after 19 hours you have still 75% of battery. you dont use the phone, is only in standby? the fully charges were with how many hours?

I have installed Battery Calibration as said, but its asking to root the device. What is root? Sorry for being noob. I am new Android phones.

Ace's battery won't stand for a day with moderate use. It's battery drains faster than any of my previous android phone. Before ace I've used Sony Ericsson x8 and Galaxy mini, both's battery can stand for 1,5-2 days. I usually put my phone to airplane mode during my sleep time from 11 PM to 6 AM and on galaxy mini's battery drains only 0-1% in the morning, but on ace the battery drains 7-12 %, it's horrible.

Sounds like you havent mastered the way of saving battery on a SGA yet. With some thrid party apps you'll be able to make it through the day without any problem.

Juice Defender, Set CPU, Auto Memory man., Autostarts and Tweaks for instance.
Use quick setting to access and switch/change the brightness, mobile data, wifi.
Check the apps that uses unnecessary CPU with watchdog, you can uninstall watchdog when ure done your evaluation.
Don't use apps such as Advance task killer(if you dont know what ure doing), it might give you even worse battery time. Many background apps doesnt use any CPU at all, they only take up RAM.

The only one I recommended from the installed apps was juice defender, and you didnt even combine my recommended apps. Try that before posting this issue.

mine stands for 2 or 2,5 days with Glsmt 1.3 rom, and wifi is always on. tried juice defender must say is the best friend of any android phone.

Hi to everyone on this thread. How long have you had your Ace & have you given it a chance to "settle in"?? I easily get 2 days+ with average use ie/ wifi/games/calls/surfing. The battery needs time to calibrate itself, no apps necessary. Takes a few weeks. At this moment I'm on 2d 15h 17m 45s with 27% left! Phone is left on all day/night & I disable wifi/3G/syncing when not required. My % stays the same overnight, no drop. Hope this helps. GrahamF. London

Hmm, cant see any changes after calibrating...

That sounds quiet unbelieveable. What Firmware are you using?
Though: Turning 3G off all the time means that you also dont have background synchronisation, right?! That would surely save some juice, I guess.

You can still sync with 2G, it'll just be slower than with 3G and saves battery, but since he mentioned turning off 3G and Sync in one go, I guess he disabled both.
During holidays I switched off 3g and sync off due to avoiding data roaming abroad and had still 20% left after 2 days with one charge.
Used it during that time for occasional SMS, gaming and taking pictures, and scanning for free Wifi hotspots.

Hi Deathmetal X, I'm using the stock out of the box Froyo 2.2.1 on 02-UK. No mods, just use the inbuilt task manager to close what I'm not using & turn 3G/wifi on & off as I need it. I don't need background syncing & I just collect my e-mails (3 accounts) & Facebook, Twitter etc...on a regular basis. I don't have loads of widgets wasting battery either, just F1 & weather. I use it a lot on wifi + games & calls/texts. Today I'm on 3 days with about 17% left. Biggest drain on battery is the 3G, trying to connect & re-connect all the time! None of this restricts my use/enjoyment of this great phone & well worth having it in my hand & not plugged into the wall! Graham. London.

Nice app_ I use CM7 before the battery is drain_ after I calibrate the battery I think my battery life increased. good_

Batter drain on CM10.1

Hello
I have a 3 year old i9000 and with the standard battery I was getting 6 hours max with MINIMAL use and Edge internet.
Not using 3G or WiFi
Then I bought a new ERD battery and did not see any change, still getting 6-7 hour max life
Experiencing this on all roms

I can see most of your battery is used by screen.
Can you click on screen and se how long phone was kept on...and I think this is pretty normal...even if you want to save a bit of battery then you couls lower the brightness

Can you post your battery results? I want to compare

Solved!!
Hi Again, finally i found the problem. There was a proces draining the 40% of the batery. It was the exchange service. I killed it, delete my exchange account and restart the phone.
Now i have a normal battery drain ,a bout one day with a normal use, including wifi, 3g....
Thanks

[Q] Help with huge battery drain on usage [TRIED EVERYTHING]

Hello guys, sorry for my bad english, but I'm not American. Well, my question is:
I bought from a guy a Galaxy S I900b, Brazilian model with digital TV. Came with stock 2.3. As I had already read enough before, upgraded to JWB Saurom with semaphore kernel, which I think is the default for this rom. Well, the phone had very poor battery life, evn on idle. Then upgraded to 10.2 CM. I saw that had some wakelocks, and with BBS and the help here, I used the Scan Media Root and my problems are gone in iddle. So, my phone goes into deep sleep and today during my sleep, only lost 3% battery, 3% battery drain on idle during about 5-6 hours it very good to me. But during use, it ends up very fast, and with GSAM and standard monitor of the android, I saw that after the screen, the Android system was what had higher %% battery. So what could it be ? The battery life is ok, checked on info, and its condition is 'good'. I use to Greenify, and close almost every game\app, so running is just grenify and ram manager pro.
So the prob just could be a app or the 'android system' ? Or even hardware ?
I dont have much time now, so any info or screenshot you want, I can provide later
Thanks

What about your connections? Do you have 3G/wifi enabled at all times?

calibrate....maybe useless, but u can try....but somehow, try bigger mAh battery, maybe.....n maybe .... it will help.
juz charge it with screen turn on till it full, n waste it to 0% till it shut down, turn it on n charge it with screen on till it full again, u ll be fine
if problem occur again, keep an eye for sneaky app that run at background (email...exchange etc) n juz delete some sys app that u dont use using titanium.
if it still occur again, wait for arc reactor battery....

I've deleted the batterystats.bin and used until 0%, so charged while off, but nothing :C
It's true that the battery needs to 'learn' ? Like, a few charges and discharges and could estabilize ?
I'll take a few screenshots right now

Callibration of you battery eg: Wipe battery stats is onluy helpfull when you get weird battery stats.
If you are on any CyanogenMod ROM you have to get used to the higher ammount of battery use by the phone. The application Greenify can help a lot by hibernating the huge battery suckers like facebook and google maps.
Some tips:
- use 2G instead of 3G
- Turn WIFI off when you're outside the house or leaving for some time
- Turn GPS/Bluetooth on only when you're about to use it
- Dont use taskkillers (they are used to free up ram but killing apps makes android restarts them and this consumes extra juice)
- Put brightness on Auto
- Use a dark theme and background/lockscreenwallpaper
- Dont recharge your phone when below 5% this can damage the battery
- A new battery needs to "Get used to" the life of being a battery xD After a few recharging cycles it will work like normal

Here some screenshots, if need more, just ask
Note: Was with 14%batt, rebooted and drops to 11-10%

i am using greenify on almost everything.
used to use ram manager, but now i've disable it.
brightness is on low
I really dunno what 2 do ... almost 1 week with it and this insane drain, everyone says that plays or browser on wifi and get almost 10 hours... my dream this happen to me lol
Remember that this is just on use, on idle it use virtually nothing, like I said, almost 3% on sleep, but is just I start use with app or browser and its gone

Screens are from a too short period of useage. Use it from fully charged, and make some new screenies This can help futher

Well i got problems with my battery too so im planning to buy a new one because this one cant even handle 3-4 hours when im doing something like playing games,or listening music...Just buy new battery with more mAh and dont get bother with this :laugh:

About 2 hours later that I fully charged, here are some ss
Just used whatsapp and opera in this time
I was thinking in change my kernel, currently I'm using semaphore 3.0 with CM10.2, is Latrop or Mackay better in battery life ?
I think its my last shot ... I'll provide a new battery next week, but i've heard some people with batt probs that even with new batt the problem persists :crying:

It looks like wifi and 3G have been kept on for most/all of the time. Turning those off while you're not using them may significantly increase battery life.
Also, related to kernels, personally I've found Mackay to be a bit better in terms of battery.
Also it looks like your screen's pretty bright if 61% of the battery usage is because of it. So if you don't need it so bright turning the brightness down may help.
Start by doing those, and see how your battery life fares first- if not much changes, then it may help getting a bettery battery/changing rom even.

So, like i said, in this 2 hours after charge, i've used opera mini with wifi, I dont use 3g. Right now the battery is less than 10%... it's strange since have people telling that can use almost 5 hours wifi and the battery is > 50%
And the brightness is at lowest bright :\
The problem could be some corrupted file ? I have the options:
- format EVERYTHING, and dont use titanium backup, since somthing can be corrupted.
- change my kernel to Mackay
- change my room back to SAUROM 2.3.6 adn semaphore kernel
I'm very sad cuz I have a very old Nokia E5 that can be on with wifi almost or more than 10hours ... and this phone can barely hold 5hour
What u suggest me to do ?

How long have you been using the rom? Roms take time to calibrate the battery and this is through charge/discharge cycles.
Alternatively, go into Performance settings and change the profile to powersave/conservative (it differs from rom to rom). Lock the min CPU frequency to 200mHz- apparently this helps.
Again, this would change depending on your kernel.
And if you have a three year old battery like mine, best not to expect miracles...

Using bout 2 days ... but i didnt knew about ' calibrate '. Good to know that
Now i've formated everything and will put a stock 2.3 and see in a couple of days the perfomance ... if gets better, I put the saurom 2.3.6 and be with it, cuz 2.3.6 on brazilian model allow to use digital tv, and 2.3 everyone says is economic.
I'll get this updated if my situation changes, if not, will buy a new battery
Thanks for all your help
Note: How long your batt last ? With high\low usage

horrible battery

Is it just for me? After a full charge the screen on time is about 2 hours.. Tried cm11 and other custom roms without luck.. When i bought the phone and wasnt on KitKat the screen could pass 4hours. Huge different!
In battery info the only program that drain the battery is the system it self . any tips?

check your rom and kernel, any overclock setting is active.
check battery usage to find what drain your battery.
Mine have 4h30 - 6h screen on (just wifi, without mobile data)

No overclock set.. Just the system thats drains battery..

@colors Battery life isn't as good as I think it could have been but at completely stock and with nothing on the phone the phones battery is pretty phenomenal, an idle Z1 will stay on for over a week, infact i've seen some phones with 19 days before now quoted within stamina mode.
Just took a pic of one in my workplace and it's saying just over 19 days, that's not too bad for a phone which is always on and capable of receiving apps via wifi (see picture attached)
I know that 19 days is excessive and no one here is ever going to get anywhere near that or even a week, unless you don't use the phone, the problem most of us face is the apps that we use and their footprint on our phones, affecting battery life and performance.
Take a good look at your apps and what you use and see what you could do without or what could be affecting battery.
A clean install will usually give you great battery if theres nothing on the phone to slow it down, eliminating apps one by one might seem mundane but it's key to great battery life, after a while you'll learn whats bad and whats acceptable.
Using the likes of CM11 could cause even greater battery drain as it's all custom stuff, not to mention that some things within the system aren't working as good as they could be, there is still a lot of work before things are perfect, double tap to wake for example is a feature which could cause massive drain.
Always perform a full wipe and don't restore anything via recovery, leave it as a bare rom until you can verify the ROM you are using is without issue.
Hope this helps

my galaxy s3 i9305 consumes a lot of battery

I have a problem with my phone. The battery precents gets low very fast. Its not problem with the battery because I checked it. Maybe I should change rom?

With a rooted phone you could try xposed framework and deep sleep battery saver. I have very good results.
Also check with wakelock detector that no process is hindering deep sleep.
S3 screen is consuming very much battery though.

I have friends with s3 and they have a lot battery precents at the end of day. My battery precents gets dwon very fast!

Have you had the phone for long? What rom are you running? Has it only recently started chewing the battery?
If you have installed any new apps since the battery was fine, maybe might to be to blame. Also some i9305's have issues with the antenna and will use up a lot of battery if you are in an area where the signal isn't perfect.
Also check what it says is using your battery in battery stats in settings.

OK, if internet and android system use up the most of your battery, then it sounds like you have a fairly high usage or some app(s) are running in the background, in which case changing roms probably won't make that much difference. Check out @MaHo_66 's guide for rooting/recoveries etc here -
http://forum.xda-developers.com/gal...covery-i9305-cwm-philz-twrp-versions-t2694249
This will start you on flashing etc. And check out the forums for info on the different roms. Other users will hopefully suggest ones to try
PS - read rooting guide carefully and follow the steps!!

If your ROM allows you to, try to deny "Keep awake" permission for some apps especially Google Play services. Otherwise you can use Greenify.
