hi i have flashed omega V7 rom on my galaxy s3 and now it charges alot slower than it did when it was stock, is there a kernel i can flash to make it charge the same speed as it did, or faster even?
it charged at approximately 1% a minute when it was standard, but now its about half that speed, maybe a bit worse.
thanks in advance
You know Omega has stock kernel .
Kernel descriptions are posted in the dev section one kernel has charging tweaks ..
Omega for me gives standard charging time although i have never measured charge rate per minute .
Might be worth clearing your battery stats via recovery .

Try siyah kernel and get the app called exTweaks from the PlayStore; if you go to the misc. tab it will show charging current through USB and AC you will be able to alter the current according to whatever you feel comfortable with i would recommend no more than 1200 mA due to excessive heat and the possibility of damaging something.
I personally have the charger set to 900 mA to keep heat down whilst charging

is siyah kernel better for battery than stock for battery?

My galaxy s2 has had battery issues the day i got it.I was getting around 6-7 hours then, thought it was some issue with firmware checked the battery usage and everything seemed fine expect for few times the android os seemed a little high , so i installed a custom rom , tried sensation and villianrom and a few others .Villianrom seemed to help battery a little but few days in and battery is again draining like fuel in a f1.So i decided its nothing about the firmware and all , maybe i have a bad phone or battery cause its draining like 1% every 2 -3 mins while browsing or doing anything as a matter of fact i get about 4-5 or at best 6.5 hours but thqts rare.I mostly use wi-fi so it definitely uses less battery than 3g . So now my question is ... As i have rooted my phone do i get
The warranty assets as my phone is like 4 months old.I know about unrooting but will that do the trick ?
And btw apart from battery issues , which seem like i have a unique case , my experience with the phone has been amazing this is definetely the best phone on market ;-)
Please respond....and also share your experiences with battery backup of s2 .....thankyou. cheers B-)
*i forgot to add that another thing that i have been noticing is the high battery usage by the display , it sometimes is as high as 80% even on low brightness to which i have found no cure...no matter what i try it lowers sometimes to about 30% or more and is back again to higher, this has furthered my doubt that i have a faulty piece. Pls comment.

I'd say 1% every 2-3 minutes sounds about right if you have screen fairly bright.
Did you do a back up before installing custom rom?
If so install original rom back, then I think you need a usb jig, which is available from ebay. This will reset your custom binary counter so the warranty peeps won't know you've flashed a custom rom at some time.
I'm quite new to this so hopefully someone else may reply and correct me if wrong.

Display uses the largest amount its relative all the figures say is that of the battery percentage used display has used xx amount . Could be battery used 5% of that 5% display used 50% as little else was used .

on regular use, my batt wear off in a day or a day and a half, but when my kid play a HD game, the battery drained in just 3 hours.
I've only tried 2 custom roms, miui and criskelorom, and I think using criskelorom combine with neak kernel is my best so far
I used the trick of battery calibaration by ram3n and battery seems to hold up a little better. Betterbatterystats was really helpful as well as battery monitor and cpu spy . But still i guess yhe phone will suffer on heavy usage or even medim .

My Samsung Galaxy S2 Battery drains heavily all of a sudden. I noticed that suspend backoff is consuming battery. It doesnt go into deep sleep either. Using ICS 4.03.I have attached Battery Stats dump file. Please advise.
Hi there,
just in advance: Yes, I have read quite a bunch of battery drain threads, but non of them seemed to help me.
Compared to GB, my SGS2 doesn't even seem to last more than a day in terms of battery life.
Now I wonder - is it just me playing around with (otherwise awesome) CM9 and battery life is actually normal or is there some kind of battery drain going on?
Running CM9 14-04, stock kernel, LPS baseband.
Attached please find BBS stats and other battery stats screenshots.
Help very much appreciated

Awake over 2 hours, 1 hr 43 min screen on, down to 62%. That's on track for 5.5 hours awake time, and about 4.5 hours screen on time. Looks pretty normal.
You MIGHT be able to squeeze a bit more juice out by playing with your sync and display settings, but that otherwise doesn't look that bad.

Have you tried to re-calibrate your phone? I once messed around with my battery and i lost 70% battery overnight when it was on 100% because i was unplpugging, plugging my phone in randomly.
How do I do that?
Just bought a 2000mA battery and it seems I still got the same 'issue'...

Did you try to wipe your battery stats? Also, I noticed that playing around flashing the Roms, requires 2-3 full charging cycles before the battery was "stable" again
I've also read the following but didn't try it (I imagine it does the same than wiping the battery stats in the recovery, but you never know, you can try it):
Delete batterystats.bin in data/system, after full charging (with Rootexplorer or another app)
Then, use it until to 90%, and full charging.
Good luck!
When is it a good idea to wipe battery stats? When it's empty or at full charge?

The CM9 has some battery drain problems because is still developing maybe try wiyth another rom and see if the problem remains

Stats seem fine to me. Your phone shouldn't drain much when idle, but once that big screen is lit up the power drains much faster. The SGS2 stock battery is not huge to begin with either. Your 2000mah will be better though, especially after using it for a few cycles. You can also try flashing a different stock kernel or custom kernel (Siyah, etc).

Thanks guys!
So charged my 2000mA battery up to 100% now and wiped the battery stats. Hope this helps.
I really wanted to stick to CM9, because I don't wanna do a factory reset every couple of days when flashing other ROMs, because I'm tired of setting up all my stuff over and over again...
Are the other ROMs really that much better? Thought that CM9 would be best, because most popular...
Or could it be the baseband/modem too?
I am on LPS right now... I've searched the forums forever, but can't seem to find an answer for:

Flash sirkays 6.1.1 ics kernel.In which you can use your phone for 2 days
Then flash hybrid rom(2.3)--I choose this rom coz it is lite and can run very smooth even in 800mhz
Then under clock your phone to 800mhz and use conservative governor

Thanks but I don’t think you understood me. Even though I do have battery problems concerning its life it is not the problem I am posting here for. The problem is that my phone is unable to measure battery percentage for some reason..

Charge your phone to 100% (421)and then calibrate it....IT SHOULD WORK
maybe reflash ics firmware or change battery or take it to repair center
Just restart your phone.
r
When I plug my charger percentage remains frozen so can’t see wen it is fully charged. And when I try to calibrate it just says 0% battery spent for example when calibrating web browsing... It is as if some battery sensor burned out or something. Could that be the case?

The thing is that I can read my battery status via hard battery calibrator script which means that sensors are still operating. but I cant recharge my phone via usb and I cant reed my battery status on it (in status bar). Also my battery time is extremely poor - like 12 hours max on very little usage (about 8 hours of me sleeping included) or like 3-4 hours of heavy usage. Is there any one here with knowledge to help me? Thanks in advance

hi,i just bought new 2.1A charger for my S3 and with current widget it shows 999mA charging rate. so S3 dont charge faster even I have better charger? Because when I play some games with wifi on and brightness on 50 percent with charging my battery % dont go up but slowly go down :/
1A is the limit. Some kernels allow it to go up to 1100
ok, now understand. maybe I can rise by myself that rate? or its dangerous for phone or batttery? Or only kernel devs can do it? Now Im using siyah kernel

Your choice but phone can only explode once and custom kernel = no warranty .
jje
oh, I dont need see explode on my table. so maybe I leave like that.
LoL don't worry about your phone exploding.
I've been fast charging for the last 6 months.
There are no adverse effects. No increase in Battery temp while charging and no effect on Battery longevity.
You can safely go up to 1500 with either Yanks or Perseus Kernel
If you choose perseus don't switch off the failsafe.
Don't expect anything dramatic though. I would say that there is a10 to 15% reduction in charge time.
You will notice a much bigger effect with usb fast charge if you increase that from the stock 450 to 1000. Especially when using a car charger.
