[Tips] Improve Battery Life on cm10.1 Rom

[dzeig]

My phone (galaxy mini) has battery life issue on cm10.1 rom, which is that battery drains very very fast. for example, i just do texting, browsing, tweeting and lil bit gaming, my phone battery lasts only for 4 hours, even less. i ve used tweaks, scripts, apps to improve the battery life.
I found these all work:

No. 1: calibrate your battery

drain your battery till your phone shut down, charge it till is full (wait till no charging sign on the battery icon - ignore charged notification on lockscreen).
do it couple of times.

No. 2:

a. change this line in build.prop
from

ro.ril.disable.power.collapse=0

to

ro.ril.disable.power.collapse=1

b. change egl.cfg
from

0 0 android
0 1 adreno200

to

0 0 adreno200

No. 3:
odex the rom (partially, so you are able to change phone's theme).

Follow these steps:
1. move these apps : contacts,
mms, phone, settings and systemui, from /system to another folder (use non-default launcher).
2. run the app (attached on this thread forum.xda-developers.com/showthread.php?t=2156287 ).
3. ur phone will automatically reboot.
4. move back contacts,
mms, phone, settings and systemui to the /system after odex has finished.

No. 4: recalibrate battery using rom
(use lastest erikcas' cm10.1 rom or goldchang's cm10)

it happens times ago.

so today i backed up the rom. then i installed goldchang's cm10 (my phone lasts up to 12 hours in standar usage when i was using this rom), i used this rom for couple of hours, and i backed it up. then i did factory reset-wipe cache partition-wipe dalvik cache and battery stats. and i restored rohan's rom. i dont know how, but now my battery life gets much much longer. it's been almost 6 hours (when im typing this thread), my battery has 29% remaining. for me it's superr.

hopefully those work on ur phone.

credits belong to
rohan , erikcas and devs for awesome rom.
no.2 point a to dheeraj (dhlalit11) for build.prop tweaks thread.
no.2 point b to clayteau.
no.3 to nixoman for odex thread.
and goldchang.

g'day and salaam.

the trick is with battery stats wipe and not with goldchangs rom...that's quick calibration..
some times old battery data might cause excessive drain..so wipe battery stats also while installing a new rom...it wont effect much but u never know..i recently saw an article about this in google tech page somewhere
but mostly the drain might due to an app, so see if the app activity is still running in background even after u killed it..if such an app exists then uninstall it u will get more battery life..

 

[dzeig]

actually, i wiped battery stats after fully charged maany times and freeze some apps too, those things didn't work.

well, like i mentioned before, i have no idea how it happens, but my battery life gets much longer, for real, yay.

yeah, but what if the 'background' app is must not be stopped i.e launcher, we shouldn't stop it right?

we talking about 1200mah baterry, righT? manufacture said it last for 6 hours of Edge, that means heavy usage, right? so, if you are using your phone a lot, that means 6 hours of internet, mms and calling, it wont get any over 6hours...for me, facebook offiiciall app and whatsapp drain battery like hell...so i delete fb, but whatsapp is must for me...same result...so no matter you do, even with deep sleep, its 6 hours of heavy usage...i also have Nokia e7, same capacity of battery, and same durability, 6 hours of heavy usage, except on nokia e7 battery goes quickly for its screen , not background app...android consume a lot of battery, its a fact, so there is no a chance that someone else calibration or tweaks can result better battery capacity...but, if you set your CPU mhz at normal level (600-248 at ondemand), you can get a good battery backup...is that cpu level its ok for you, than its ok..but running cm10.1 with that cpu level for anything else but music and opera mini, its useless...so, what ever you do, its still 1200mah capacity, remember that...your usage, is something else

take a look at my first post, my phone had has three 'phases':
1. rohan's rom before (poor battery)
2. goldchang's (awesome battery)
3. rohan's after (awesome battery, yay!)
my phone usage on those three is nearly same, even the number three i suppose is the heaviest because i haven't charge my phone till now (i charge whenever battery came to 4-1%, it's long enough from my last charging). take a look at ss.

here's a thread about battery calibration

*there's a link tells that battery calibration is a myth, IDK

 

[chemicalrage]

About Battery Callibration, I dont think it increases battery life. It just resets the .bin file stats to show the battery indicator (in status bar) correctly. Do it once after you flash a new ROM (after charging 100% + 15-30 minutes) & then calibrate either from CWM by resetting battery stats/ using the app in playstore called battery callibration . It will then show the correct battery indications.

Many people dont do this and then they complain about battery dropping suddenly but it is actually not dropping. Its just the indicator which is wrong.

so is that means when indicator says phone is fully charged, the fact is not full charged?

Only the first time you flash a new ROM. Just let that notification come and then charge an extra 15-30 minutes & then callibrate once. Thats more than enough.

Re: [Tips] Prolong Battery Life on Rohan007's cm10.1 rom

I tested battery with Extremely Heavy and Harsh usage. And it lasted for 1:40 mins.

What was the test?
Running whatever the phone could.

So what was running?
1. Wifi(scanning mode, not connected to any wifi)
2. Bluetooth (scanning mode all the time not just 120sec; not paired, connected with any device)
3. GPS with Gps essentials app: struggling to lock GPS for 15 min, then locked for 10min, then again lost the lock... in short it was alternating in lock and unlocked states with time gap of 10-15 min as I was indoor)

4. Video Playback: Alternating Background/foreground playback of 320x240 to 640x480 res Videos with mx player

5. Screen brightness 100%, wake lock on, speaker volume 50%, cpu usage 600mhz ondemand

6. camera on all the time(+ small 10min video recording), with gps essentials app

7. Egprs: 20min surfing, sync on all the time(no social apps)

8. May be I forgot something.

Specs:
Device: galaxy mini
ROM: CM7 autoradio v8 or CM10.1 (forgot)
Battery: A newly purchased genuine 15 day used battery.

Note:
Test date: 6-feb-2013
Everything I mentioned was CONSTANT, SIMULTANEOUS On for all the test period.
Battery was calibrated which was showing true stats.
I do not have any battery usage (right now searching for any screeshot if i captured, mistakenly )

phew, so harsh test. how did it managed. In normal scenario the battery only last for 4-5hrs with no gps, wifi, Bluetooth, camera or 3g on. Maybe I will switch to Stock rom for long lasting battery usage as battery charging even when the phone is off is totaly, wierd.


Like post? Just Thanks me in ur hearts, no need to "presss" thanks.

extremely dangerous, do not try this at home .

i thought GB stock rom has a poor battery life, even for standard usage.

Thought not, I'm switching to GB only for pure/normal usage with no root, no data hogging apps Just for few calls, one hour egprs browsing, enjoy local videos and music(no streaming).

We would be glad if you post the procedure here or in the general thread... Do make it noob-proof.
