Battery life - AT&T Samsung Galaxy S II SGH-I777

Okay so I was wondering I have a galaxy s2 and right now it's rooted and running CyanogenMod. I'm also overclocking and it's been rooted for about a week now. What is the average battery life for the galaxy s2 because I feel like my battery is going too fast. If I play games in the car for 20 minutes 10 to 15 percent is already gone. Sometimes if I search the web for for 3 minutes I would lose the percent of battery.

That sounds about right for me lol, without overclocking. That'll definitely hurt your battery life.

Yes thats an overclocking disadvantage. Turn it back to default i.e 1200 Mhz and try using Sleepy or ondemand governor combined with noop or SIO as i/o scheduler. And find out the background apps like facebook which drain your battery. You'll find much difference. Hope this helps you.

I would suggest getting better battery stats app to get a better handle over ur battery consumption, i use this app currently and although i have not fully understood what the color coded lines mean fully, it has helped me figure out which app(s) consume a lot of battery power

yes .. thats well known when the phone is overclocked .. normally (default CPU settings) running custom CM or AOKP you should get around 2 hours of screen on time.

[Q] Your Max Battery Life!

What have you encountered as your maximum battery life?
If the figure is hmmm too much, tell us what you used!
what do you mean? maximum standby time or usage? is it the milivolt? please elaborate
Around 1½ day i believe. But normally ill charge it at night where it has around 20-30% left
edit:
Usage: Music(+DSP), SMS, a few calls, Web browsing (2G/3G/Wifi). Dont really play any games but I do watch musicvideos sometimes which is takes around 15minutes.

Lmfao yeah that happens. But you can get Power Saver form the market. It really works. What it does is clock down the processor depending on what profile you set the app to.
Even though, today I haven't used the phone much and it's been discharging from 16 hrs and it's still at 60% (with Power Saver turned off). I've only used it for light texting today and that's it. 3G is what sucks the battery dry. Sometimes I use Edge only (2G) and the battery lasts me a whole day and more. The other day it lasted me a whole 24 hrs and it was still at about 19% left. I'm guessing the battery can last long or short depending on the usage.

But he didn't use it. Still it's a big drain at around 1%/1.5h, comparing with the x10 mini pro with 970 mAh battery which drains at 1%/3.5h....
Cyanogenmod for ace isn't that optimized for battery life.

With Juggernaut Rom, brightness turned down and web/wifi off I can literally get like 3 days almost if I'm not texting heavily. As soon as I turn internet on I'd say a max of 12 hours. The best battery life I ever got out of it was BeastMod, CPU underlocked to just 1ghz and brightness turned down. Even with web on, still got me almost 2 days - sync off.

What gives better battery life gb or ics

Hey guys does gb or ics make a different in battery life and if it does how big is the difference and does stock gb give the most battery life or does a Rom i know you Guys don't like Threads about roms and there battery life sorry but this is just generally ics stock or gingerbread rooted i spend alt of time on the internet and Im in jersey so i don't use lte i use hspa + so what's the best way i can get the max out of.my battery thanks
Sent from my SAMSUNG-SGH-I717 using XDA
gb, but custom kernels with undervolting with increase battery even more. ICS will be even better once source drops and we have custom kernels for that as well. This is because ics can clock lower and still be smooth due to the gpu rendering that is finally integrated, and should've been done that way since day one. But until then definitely gb.
^^^this... Was getting 4+ hours screen time and 1 day 4hrs battery with GB. that was on the oc'd Rom @ 1.82 with undervolting everything below 1.5 and over volting 1.82.

The leaked ICS ROMs had very poor battery life for me.
My best battery life on GB was 13 hours with 6 hours of screen time.
On ICS, my best was 5 hours of screen time on Noteworthy Beta 2. Only did 1 charge cycle, though.

It depends honestly. Somedays with ics i have high standby drain and apps galore sucking my battery down, other days I get almost 4 hours screen time.
Dags alpha2 seems a bit better than alpha1. I dunno about seraphim, I promptly returned to to alpha1 once I seen baby blue text on white in my apps.
I'd rather keep charging than deal with GB.

What are you under volting 1.5 and below to? And when you say what you are over volting 1.82 is it the only one over 1.5 that you are over volting or are you over volting everything from 1.5 to 1.82?
Also can you list what you're over volting and under volting to? I'd like to try to see if I can get the same results.

Currently on ics alpha 2 so no kernel to do this.
When on GB i was using DaG's OC kernel (or dagr8's sorry getting them confused right now, tired will check and edit l8r). J only overvolted the 1.82 setting. As for undervolting i pretty much looked ar what cpuspy said were the most used and using systemtuner set those down one notch on the slider. The ones used less frequently i set 1-2 notches down on slider. only methodology i used and was done over a period of time pushing to see if any problems/fc's occurred. Never really got to the point where that occurred as the ics leak came out and i jumped to it. Did not make a screen capture of system tuner settings or keep a list of final changes.
Oh yeah, i also get the min frequency to 192 and that seemed to quite a bit especially when apps were forcing 'stay awake' mode. That, i feel, is the biggest difference between my GB battery life and ics. I can get 1 day out of ics with 3-4 hours screen time but sometimes an app will force stay awake and the drain is quicker.
Biggest battery saver for me is using wife vs lte. <<wifi i mean word completion error but don't mind using wife sometimes too

Hello.... from Windsor Ontario Can on the Rogers Wireless network using GB SauRom Rom. .... on the stock 2500mAh battery I get 4hrs if I'm lucky with the screen @ 25% and the chips @ 1.5gHz.....
How in the world are you guys getting more than that?? I stream HD Video most of the time.... don't make any calls and surf.... most of the day I'm on WiFi.... I have no idea how you get these times of over 4hrs... I'm lucky if I reach 4hrs.....
All good now though. ... now I have 2 batteries @ 5000mAh & 1 battery @ 5200mAh so now I'm @ 1.7 or 1.8gHz and I'll get 7hrs ......then I'll Swap to the stock battery for when involution of work.....

If I use the 5000mAh batteries at home they last pretty much all day but most of the time I only use them at work.... feels too bulky in public. ..... I could get the 3060mAh batteries that are the same size as stock in eBay..... but at like $10-12 for the 5000mAh batteries it's all good. .... I have almost unlimited power... so I'm OC at 1.8 most of the time. ...lol
They should start building these phones with Huge Screens with Solar Cells to charge on the fly.... I know there's one out there already but never really took off.... these phones need those Solar Cells........

Ffs can we not have a battery life thread started every single day?
Battery life is the most subjective thing, it all depends on how you use your phone, what apps you have installed running in the background, what you have synced, location services. Etc...
No 2 people well have the same drain.
I'm on stock ROM and subscribe to Rogers Toronto. I get about 4 hours too.... My usage sounds similar to yours as well. Thanks I will pick up extra battery soon.

12 hrs is not a good battery life I usually get around 18-22 hrs with moderate use, wifi on for 6-7 hrs. I have removed all the bloatware, which itself eliminates useless battery draining processes.
End of the day it all depends on your settings and use. But Leaked JB is well known for bad battery life. Hope that gets fixed in official release.

It looks like batterydrain is good when not using the phone much, but not so with more use. I have been using it a bit more than usual today, and after about 7 hours from unplugged, and a little more than 3 hour total screen time (minimum brightness), and 1,5 hour web-browsing, 1 hour playing music, the battery was below 15% (screen using 45% of battery) and I'm really not too happy anymore...

I have yet to have a phone that did not get improved via battery life from a custom ROM, even just a debloated and streamlined version of the stock one. Fully stock roms tend to just have too much crap on, and in, them to have wrangle out max battery life, max performance, or a truly optimal mix of both.
Using NOS underclocked to 1GHz undervolted 75mv across the board all set to conservative and 10 hours later 3+ hours of screen on data downloading GPS etc 60% Battery Remaining... Very nice

I'm getting 16-20 hours with around 4 hours on time. I'm underclocked and undervolted , brightness at 25% most of the time, and I just supercharged my phone so I'm waiting to see if that'll help it. I know I've got my standby battery drain down to one percent every 2.5hours. Left it off the charger last night and it was at 98% when I woke up 5.5 hours later. Just gotta play with the settings and tweaks.

I get good battery life most of the time. But I am at the ball fields with my kids a lot with no way of charging mine or my wife's phone.
So I got me an Anker portable battery and it saves me all the time. I purchased the Astro E4 13000mAh Dual USB so me and my wife can charge our phones at the same time without looking for a outlet or going to the car. We can both charge our phones 3 times each on this thing before its dead.

As far as battery life is concerned, wifi > 3g > 4g.
But if you're not connected to a wifi network, leaving wifi on will drain your battery. It may not be by much, but I always turn wifi off when I'm not on wifi.
