Hello.
I have a huge battery drain while browsing on my sgs2 running CM10 and recently siyah 5 RC1 (before original cm10 kernel). It is hard to find threads like that, there is always talk about wakelocks and other drain issues. So I wrote a new one.
The battery drain surfing the internet over wifi is huge compared to other things I use my phone for. Example: Streaming a 720p TV show over wireless and watching it on MX player drains about 3x less battery. How is that possible?? I have no problems with wakelocks, the screen on time is usually around 3-4h, BUT, only when using rss and other apps - not touching the browser. There seem to be only a small difference between CM10 original, Firefox and Chrome, perhaps Firefox drains the least, though the power is draining so fast that its hard to compare.
So, is there a way to somehow limit the usage of the CPU or/and GPU while surfing, if this is the problem. Or does anybody have another solution.
As I said, no wakelocks and the battery lasts about 2 days if using apps for getting info-news... + only a little surfing using a browser. I had the same issue on CM9, Slim ROM and others.
thanks
Try to find a thread that has battery tweaks. You can try under clocking to 1000mhz or even 800.

It is hard to find a thread like my question. As I said my battery life is just fine. I tried many different setups (governors, shedulers, kernel, CPU and GPU steps and voltages). What I can not understand is how watching a 720p TV show streamed over wifi consumes 3x less power as opposed to only surfing the net. While browsing it seems the battery percentage is dropping every minute.
Why doesn't that bother anyone else?? I am sure its not only me. And as I said, I am happy with 1200mhz, cause the phone runs smooth and it lasts about 2 days. I only wish net surfing wouldn't take that much battery. It's definitely to much!
There has to be an answer to that problem. Is there a way to limit only the browser rendering to a specific CPU/GPU clock...?

Yes, with SetCPU.

On a stock Galaxy S II (1.2GHz) what is the battery life like when using 3G HSPDA (7.2mbps)?
And also gaming like Gameloft HD games?
thanks,
I only ran stock for about a day, so I can't give much of an estimate for that, but I get about 5-6 hours of screen on time, and easily two days of light use. I'm currently running HyperDroid with a mild undervolt and no overclock, but I assume it would be pretty similar for any Samsung-based ROM with bloat removed. As for 3D games, I can drain the battery completely in about 3.5 hours (Dungeon Hunter 2, Eternal Legacy). I wasn't able to undervolt my gpu stably though; that would probably help a bit.

hummm, maybe an extended battery will do the job.......
I think its better for you to have a spare battery.
On stock, and doing all you said, I couldn't get more then 10+hrs. (absolute max.)

It's Display On time what matters. As long as you are getting 5-6 hours of it you are absolutely fine. Standby time doesn't matter.

I am fullday on 3G HSPDA battery life is maximum 14hrs...I use whatsapp alot so my battery goes more on display almost 50%. I have Samsung Vibrant too and on 3G HSDPA there is no chance anyone can get more than 15 hrs.
Is it actually worth the effort to undervolt the sgs2? I've already Underclocked to 800mhz and was just wondering if Undervolting saved a visible amount of battery? Cheers.

Ive read some very involved and lengthy debates in other threads about this. Mind numbing some of it.
I believe UV and UC do save some battery but......
From my experience ive found I get more real world battery savings by freezing unwanted apps and processes, set syncs to be more realistic, and using WiFi, Bluetooth, GPS only when I need them. Also experiment with modems.
I try to get the screen on and awake lines in battery usage to mirror as much as possible. Of course because of syncs, calls, etc there is always a small amount of awake more than screen on.
On LP2 at the moment im getting around 4 to 5 minutes difference over a day reported by bbs and im not choking my device at all.
No UV or UC at all.
Happy with that.

It really depends on how much you undervolt the phone... As seen using the phenomenal kernel (speedmod with undervolting), that it does infact provide better battery life when compared to the standard speedmod kernel...

there might be slight increade in your battery life.. but if you dont undervolt it correctly your device may freeze at times with random reboots!
it has happened to me..

Honestly to me, there isn't much difference when I use SetCPU/VC to undervolt kernels like Siyah and void. Better ways to save battery should be to reduce screen brightness, reduce syncing intervals of apps and turning off GPS/BT/Wifi when not in use.
You should however try Phenomenal. It's undervolting does save some bit of battery as compared to stock Speedmod according to many users. I myself also felt better battery life but I have a feeling it's just a particularly good battery cycle (happens occasionally on every kernel) and it will return to normal, gotta test it for a few more days!
Any Draw Something users having the same problem as myself?
Currently on Hydrog3n rom but I have tried others. Usually charge my phone via laptop but when playing Draw Something phone still discharges faster than its charging.
I haven't noticed any battery drain while playing that on my sgs2 running cm9

Doesn't affect my battery whatsoever. Must be your phone buddy.

On CM9 it cause a huge battery drain here too. If I use it I loose close to 1% per minute
Using sensation rom no batt drain at all
Mod or Die
change kernel.
speedmod look the best
htc hd2, hyperdroid (fikret) - i'm also experiencing a huge battery drain when playing draw something :/
Am also on CM9 with Nexus One (BCM ICS). Draw something is indeed drawing lots of battery power. Phone gets immensely hot. Running the Tiamat kernel from March 14
No battery drain on neat ROM

How fast does your drain I play draw something alot, I don't seem to notice it to drain that fast.
I have the same issue here with a LG optimus 2x, draw something consumes all the battery in 2 hours or less. (with stock rom)
Try Different Kernel
Speedmod, Siya or NEAK
I was wondering if any of you people could be kind enough to give me some more battery tips for my new SGS3.
I'm getting around 4-5% / hour battery drain on standby. I have 2 GMail accounts on sync.
Here's what I've done:
-> Removed Kik Messenger because it was commandeering an outrageous amount of Wakelock Time (about 5-11% of Wakelock Time in 4-7 hours).
-> Installed Omega v5.0 (latest).
-> Still on Stock Kernel
-> Changed my WiFi Policy to "Only when Plugged in"

What does Facebook sync anyway? I always thought it was just once to get the contact pictures. I will disable it now
I've been using Foxhound and Siyah kernel, super combo. I can honestly say it's the best performance/battery life on any android device I've used, 6+ hours of screen on consistently - wifi/gps on, 3gmails autosyncing, autobrightness, 1hr>calls, 50+texts, light browsing, redditt, Google Music... Battery life is so subjective though depending on your apps, usage, cell signal, etc.
Experiment! All things being equal, in my experience its the kernels that make the biggest difference in significant battery life improvements, with the exception of stock roms vs. AOSP/AOKP, battery life doesn't differ very much minus bloatware in the various roms. And if you're a flashaholic like me you'll actually have to wait a few charge cycles to get an accurate representation of battery performance for your phone.

Thanks for the big post! ^v^. I am going to flash the SiyahKernel. But after turning Facebook Sync and the Wifi Policy (which I found out about today).
My battery is at 93% at 2h 01m 05s (also my battery goes down to 99% as soon as I take it off the charger). So thats 6% in 2 hours which is 3% / hour ! Getting there ^^
Apparently going to 99% immediatelly after the charger is normal for Samsung devices. So I wouldn't count that as reduction.
I dont use aftermarket kernels and roms, I have disabled a few stock programs I do not use and get a very decent battery with the 2x battery saver. I had already ordered a secondary battery which is on its way actually as well, so ill be covered from there on

99% right off the charger is a feature .
Undervolting is an option as well.

Oh my! Great feature! Do you know of a guide on how to do that, or is that just a fancy term for "underclocking" ^v^
As I am still on stock kernel I am obviously still on stock speeds but I'm going to flash SiyahKernel after I finish uploading photos of my A77

I don't think there are any OC/UV guides in the SGS3 forums but you could search XDA to acquaint yourself, there many writeups on the subject. Make sure have ADB and are familiar with it before so you can recover if necessary from any mishaps. Every processor has a different tolerance to OC/UV so there isn't a tried and true method of implementing it you just have to use trial and error.
I won't get in to it too much but undervolting and underclocking are related but different. Undervolting effectively ask the processor to run with less power from the battery at a specific clock speed or frequency. Underclocking would be reducing the overall frequency of the processor depending on the load. They can be used independently or together.

Ah thanks a-lot. Would creating a profile to limit the CPU to 300 MHz MAX during screen off save battery also?
I have SetCPU installed and have flashed to SiyahKernel now but haven't fiddled with it yet.

Download extweaks from the market instead to configure Siyah. Extweaks hasn't been optimized for the SGS3 yet but it works better than SetCPU with Siyah, it also has descriptions of what each setting does.
If you aren't a gamer you could even toggle two of the cores off, definitely will increase your battery without much if any performance hit in real usage.
just noticed that my battery still drains when im playing a game while the phone is charging(plugged into an outlet). i'm using siyah's kernel. should i increase the charging mah? it's currently at stock setting 1000mah.
im on ARHD 2.3.0 (ics). i never noticed this problem before while browsing the net etc. just recently, i installed a few games and started playing on my phone.

the same problem happened to me too what worked for me was that i took out the battery and reinserted it and i also change the charging mah to 1200 (i'm also using siyah kernel)
This is not a problem just for you. This is normal..
Just don't play heavy CPU and GPU usage games while you charging.
Changing mah is risky a bit. You warned..

Definitely agreeing with oulouloul on this one ay, Changing your mah can result in over heating your battery and damaging your phone,
Is there a option in the game to turn down graphics maybe?
i normally look for that just to save some battery anyway
interesting. it never happened on my sensation when playing GTA3. i guess the quadcore is too powerful
