[Q] Heavy battery drain

Hi,i use ficeto´s jvh rom and my battery is very fast down.when i go to about phone>battery use have i 49% displaj and friend have wildfire and he have only 2%.how to solve this?

i didn want to say this,.. but this is stupid question.
If you use your device long time.. then sure the display gets higher priority in battery usage. Even you dont do anything it consumes battery.
It must be something consumes the most.
Your friend have rarely used his phone at the moment you checked with his.

but where is problem?4 hours and from 100% to 32% and i don´t play game and when i sleep battery lost 34%

MULTIPLE posts on battery drain use search and read them .

[Q] Bad battery drain, new SGS, tried everything

hello,
i've had my SGS for a little over a week now. from day one i noticed battery drain but i thought it was normal for a new device. i flashed darky's 10.1 extreme on the second day i got it because it was very slow and had a lot of bloatware ( i wasnt very patient and i flashed at 95% or 96% battery), the drain was still there. i let it go through a few recharge discharge cycles and no improvement, so i used an app from the market called "batterycalibration" by marosige, no improvement and it the reading would drop to 99% or 98% after taking it off the charger.
i did a little digging and discovered i had the android os bug (was over 50% usage usually) so i used titanium to wipe software update and samsung account, and froze the first, didnt help by much
i then flashed darky's again at 100%, and now it still reads full charge after removing charger and android os bug i gone (reads 4% system and 4% os), but drain was still there. i emptied it to the point it couldnt turn on anymore then charged it from wall charger while turned off to 100% while i slept
i woke up and tested it by playing a game (Blastmonkeys) for like 20 mins and the battery went down to 90%, that was less than 2 hours ago, and now its at 87% and it was completely idle
notes:
my brightness is turned all the way down with no animations but display reads 54%, wifi is usually on when im home but battery stats show 6% wifi so i dont think its a big problem
also, the device was bought locked in france by someone else and im in egypt, so i dont know anything about warranty..
im sorry for the long post but i tried to be as detailed as possible...

hello,when i upgraded my sgs to 2.3.3 i also got battery drain and android os was consuming hell lot of cpu about 70%,..,.,then i flashed 2.3.4 jvp i didnt get any battery drain in that firmware then i upgraded it to 2.3.4 jvq this also donot have ny battery drain..,,.i recommend u to flash it and try it once

will try, but isnt darky only compatible with JVH? what happens if i change to JVQ?

see jvp and jvq are bug fixing firmwares and i didnt use any custom rom ,..,i have stock firmware which i just rooted and didnt use any mod or rom.,,.,.jvp and jvq are stable roms diffrence between the both is that in jvq browser is improved gallery improvement,.,..,etc

As far as I know, the percentage not being 100% after unplugging is normal. To prevent wear on the battery, the phone cuts the charger after reaching 100%, and restarts charging when it reaches ~95%.
I don't think a 3% drop in battery over 2 hours is uncommon. Wifi and data connection will pull a lot of power if on, even in standby.

Normal, this phone drains about 20% battery per hour of screen use, slightly less when watching video.
2-3% drain over 2 hours is also pretty normal if you have wifi/sync on.

I just got my SIM card replaced today. The one I had used before was about 12 years old. So whenever you-re having battery issues, make sure your SIM card is not the cause for it .

[Q] Extreme battery drain

I am experiencing an extreme battery drain with ALL the roms i tried.
The battery lasts maximally 5h, with 20-40mins of 3g browsing.
Currently at 38%, display max brightness, 2h 12mins usage,78% in battery use / Opera Mobile usage 22 m
ins, 9% in battery use.
13h since last recharge (i went to sleep).
Also my battery magically charges itself while on standby, up to 4% per hour.
Im pretty sure my battery is calibrated, even if it isnt it would give me the same power.
Also it heats up to 59c (even when i wasnt on 1.2GHz kernel)

I think u need a new batt. Same thing was happening with the iphone and untill i've replaced the bat the same thing happened.

.
Thought so.
Will flash stock 2.3.5 or should i flash 2.3.3, which is the latest official for my network?
I think it doesnt matter...
Well the guys in the service are a$$es so it will take them about 2 weeks for it...

i'm not sure tere is such thing as stock 2.3.5 and i think only MIUI has this. Last is 2.3.4 but i might be wrong.

There is xxjvs that is a 2.3.5 firmware

No your battery isnt wrecked neither magic took place its just that ypur battery stats are messed up!
Fixing them-fully recharge your battery until it shows 100% then switch your phone off and then let it charge for another 1 minute then go to recovery mode( you have cwm recovery right?) Then go to advamced then delete battery stats from their and reboot your phone ! Then for best result ypu can fully drain your battery to nil unt it switches off! Your battery stats should be now fully fixed ! Dont worry for deleting battery stats system will make them again in a few minutes or on a reboot !

Battery

Hi guys! I have a dilemma: about 1h30m ago i unplugged my phone from charging was 98% battery, when i looked just now 82% i said to myself no way so i looked at the battery: gpsd(???) 63% of the usage and it kept my cpu awake 1h6m... what the heck is that? i took another look with zdbox (if anyone could suggest a better app to view this stuff it could be great) and it didn't show anything suspicious i mean the biggest drain was by pure calendar grid about 6%...

my battery used to go down really quickly but now im using lulzactive governer in devil kernel (CM9 Alpha) its a lot slower drop when on standby.
eg i put a fully charged battery in the phone 3 hours ago and its just dropped from 100-99% over this time, although wasnt used much only sent a handful of texts.

for a better battey live , i recomandet 2.3.6 jvz stock , without flash roms , roms have problems with optimization on how its work , its use more resourse that normal
stock

thanks for your replies but i've been using this rom (signature) for a while now and i haven't seen this kind of drain until today and i don't know what that was because the phone was on stand by.... i have't touched it and that "thing" used up about 16-17% of the battery in 1h (keeping the cpu active)

For more id:ghitamcl

Please help !

guys i dont know wtf is this ...my phone battery is 100 when i shut it down and reboot it is 14 %..after another reboot it is 50%..and in a custom recovery while flashing a custom rom and during the first boot IT NEEDS MORE THAN 30 % ..it drains more thatn 15% just while flashing a ROM..(viper rom etc..)
now while normal using the battery doesnt drain like hell..it gives me 5 hours SOT or even 6 ..what i notice that my device is heating up like hell in nomral using (facebook messnger and facebook and whatsapp)NO BACKGROUND APPS RUNNING just these apps..
do you think i have a bad board ?or i have a dead battery ?

Hi TS, Im not an expert on any of this but what I suggest is to download and install an app to check you battery usage from full to atleast 10% to have a better look into things. It most likely that something is making your processor to run in full resulting in need of lot of juice and making your battery heating much.
Also as far as I understand, it can also be factored by the kernel you are using.
Again im no expert so please be guided accordingly.

Flashing ROMs and booting for the first time drains a lot and your phone heats like hell while updating apps. That's normal. Facebook mesenger and whatsapp are known to be really big battery drainers, and if they drain your battery, they heat up your phone too. If you can get 4-5 hours SOT on one charge, you don't have to worry about the state of your battery - it's good
