I bought my Samsung Galaxy S2 a couple of weeks ago from a friend, it already had a custom ROM installed, I think CyanogenMod. I use the phone mostly for internet browsing and watching YouTube videos but the battery seems to drain very quick. It lasts for 4-5 hours. I went on Settings menu and checked the battery stats and most of it is taken up by screen, I have it set to full brightness and I prefer it like that. So is there any way to get a better battery life or is 4-5 hours normal for an S2?

If you get 4-5h screen on time with full brightness + web surfing and youtube... well your phone is one of a kind.

4-5 hours , browsing, youtube, full brightness .. thats more than enough mate. look at you battery usage screen statistics... if it is more than 2.5 hours everything is fine
Hi. If your phone is from your friend and the battery drains very slow, its one of two things: 1) is that your friend has used it alot while it was charging, because that actually worsens the battery life. 2) is that you're just using it on high brightness. My suggestion is that you switch to auto brightness and you buy a new battery

I am an owner of optimus one for 5 days now and I want to share some thoughts about the battery.
I know that 1500mAH is a very good capacity, but I can't say that I am really satisfied with it.
I have pretty much set everything to drain the least amount of battery, like:
A) 2G only
B) Brightness at 25%
C) GPS off
D) Auto updates all off
E) No background apps that take power and
F) Turn it off at nights.
I get about 2 days and I don't think that this is much.
How much does your optimus one last and what have you done (if anything) to optimize your battery performance??
Mine has the same battery life in the same conditions
Don't think there is anything you can do about it..
I guess all the touchscreen android smartphones are +- the same in terms of battery..
Mine lasts about the same as yours too..
I get (easily) 2 days with 3G on during the day, automatic sync of calendar and contacts & facebook app. I charge it every other night and reboot after charging.

why rebooting after charge?
I believe that 2 days that already a very good range! I mean, "cellphones" today are computers! Even without any background application opened, you always have some services running. It is normal that you can't keep it alive without charging for a weak...
Anyway I think that 2 days isn't to much and it should be better. If I'm not wrong Samsung Galaxy S keeps about 3 days and more. It have AMOLED, but more faster procesor and my phone keeps only 2 days even though I don't use it...

From my experience with mobile phones (from nokia 8310,siemens sl45,nokia 6310i,sharp 903,nokia e51/e52, k810i and now the LG P500) only the E51/E52 would last me more than 1.5days under my usage,so I consider that the lg with all of the services running can keep about 1.5days is very good...
I have a Galaxy S and it barely lasts a day - even with JuiceDefender. I'd be pretty happy to have a 2 day battery life.
Was the battery calibrated properly?
Several rounds of full charge and full discharge.
From what you say, you might have done only 2 or 3 cycles...so maybe it'll improve slightly over time.
Also 2 days is indeed good.
Samsung Galaxy also about 2 days with conservative use. 3 days is probably for highly optimized setups for juice savings, I couldnt achieve that unless I dont use my Galaxy S .
I just found this nice app that allows you to save some battery by throttling the CPU frequency to a lower value when not used: setCPU
get it for free here: http://forum.xda-developers.com/showthread.php?t=505419
It does require your phone to be rooted, I'm afraid...
Here's another program which promises to do the same, free from the market:

Kinda useless, since O1 kernel already has a cpu governor that switches CPU frequency when it goes in stand by mode
Just got my Optimus... and yes, the battery life is about 2 days with moderate use.
But that seems damn good actually. Considering these are just mini-PCs nowadays. Try running a laptop PC that long on just the battery
I just tried using advanced task manager as a user said in gsmarena..
My battery lasts more one day...but the phone is a little slower too..
I currently have a Galaxy S and my missus has an LG OO what puzzles me about the LG is when you check what drains the battery (which incidently only lasts about a day with both phones) the Galaxy S screen drains about 75% of its battery but on the LG cell standby drains around 80-90% what on earth could be using so much power when in standby. There is very little syncing going on and GPS and Bluetooth etc are disabled.
Any ideas?
Weird. I got mine to last 2 days and still have ~55% battery remaining (which means about 4 days until it's completely off). My config is pretty much the same as the #1 post. I even browsed the web with wi-fi and played some games (for like 2 hours).

Hi,
What is the battery life we may expect from a Galaxy S2 ? Mine (from fully charged) lasted only 3-4 hours surfing the web using 3G, maybe including some wifi usage, however screen was dimmed down. Isn't the battery supposed to last a little longer ? The phone is new and I am on the third day now. Is there anything wrong with my device or will battery performance improve after some battery cycles ?

Mate 3g browsing on the sgs2 does kill that battery in 3-4 hours max.. that is actually the time scale most reviews give.. i know its a pain i hate it myself, but ull find generally using the phone ie camera, music etc gives you a longer battery. The browser rocks! but its a serious power drinker, i did discover that some sites are saying that using a 3rd party browser helps things abit e.g dolphin or opera. It has something to do wiv the gpu accelaration which enables u to do things like play 1080p videos in the stock browser and the constant smooth perfomance
oh and i found the battery does improve after a few cycles, but i think thats mainly due to the fact u tend to not be constantly playing with the phone al the time
Yep, 4 hours tops for me screen on usage.
Using Juice Defender which helps a bit..
Abouth the battery...
Earlier this evening my phone was at 28%, when i picked it back up an hour later it was 31%????
I watched the battery graph and it showed a Yellow line going upwarts slitghtly., is that strange??
Afterwards i saw green going down and than up again. I will post a pic of it.
Seriously, there are 5+ battery threads already, what is so specific about your case you felt the need to start a completely new discussion on it????
Fully charged this morning, moderate use throughout the day, on 52% now after 16 hours. I'm happy with that.

Battery now at 66%, after 20 hours and 6 minutes. Android OS running at 32% and it my largest process.
2% drop in battery over 4 hours with Android OS running at 32%... android OS bug my arse...
I wonder what would happen if people actually used their phones for talking.
I pre ordered this and waiting shipment. I can compare with the atrix i had, that the battery life was not to shabby but it had a 1900mah battery.
You can't expect amazing battery life with this phone
4.3inch screen
AMOLED+
1.2ghz CPU.
if they made the phone a bit thicker a tiny bit they could of put a bigger battery in there but samsung wants to compete with apple on thinest phones.

well after the ke7 fw update my battery life seems to have improved
Doesn't sip too much when it's idle but mine tops out at 3.5h with screen on

Must say this is the only dark spot in otherwise excellent phone.
Well still haven't got one and that doesn't discourage me at all

Mine is run about 1,5-2 days, not so intensive usage.
OK so today this is what I've done with my phone:
2 hours of music playing via headset
half an hour of music playing via external speaker
half an hour of voice talking
like 100 messages sent/received
30 minutes of internet/facebook browsing
2 albums of 100 MB each sent via bluetooth.
10 minutes of office editing
It's on 35% now and that drained after 11 hours(with the above use). Is it normal? Is my battery faulty? Is it an overuse of the phone?
That sounds completely normal for your SGS2. That's a lot of usage right there you know.
A custom rom based on android 2.3.4 (and up) and Juice Defender will certainly give you double the juice. It does for me!
That was good enough. 4-5 hours screen on time us the most I get..wifi and 3g on, push naik, stock room on speed mod kernel.

Sounds about right for that amount of usage, 100 texts in 11 hours day though crikey
BTW Juice Defender Ultimate will use as much battery as it saves so it is not recommended, this is coming from someone who used to be a huge fan but i was advised to uninstall it and ive saved loads more battery without it.
So am I, jonny68! Works good enough for me!

I use JD free ver., balanced profile, right now and i have to say that at the moment works really good. It impressed me!I'm on stock. i surfed the net for 30 min(stream video and sites) my battery is still full. Usually it would be 1/4 less.

Better Battery Life
In stock gingerbread I usually got 1 1/2 day of life with 2-3 hours of screen on. With CheckROM v6 I got around 2 days with 4 hours of screen on. Now with ICS and CF-root I got with the first full charge 1 1/2 day with 5:30 hours of screen on!
I froze all the junk that comes with the ROM, I only have a partial wakelock AudioOut_1 that is driving crazy. So far I'm quite happy with it.
Please search the forum we have so many Battery ICS threads already!
Battery life is def better with ICS, have you calibrated your battery since the update?

I'm not having any real battery issues myself, but since quite a few people report it I decided to call Samsung and ask if they will provide a rollback to 2.3.5 or what they could do to alleviate the issue.
And the answer was, as a technician had told, to solve the battery issue I should do the following:
1.) Charge the mobile to 100%
2.) Let the device drain battery as "normal" until around 9%
3.) Then open applications that drain battery fast until the phone shuts off
4.) With the phone in off-mode and drained recharge it to 100%, and do not turn on the phone at all during this time
5.) Turn on phone, and the battery life should be back to normal
Seriously, this was the official answer I got from Samsung support technician. Sounds like some old woman's advice, but hey if anyone with battery issue want to try then why not. At any rate it can't hurt

Isn't the whole "battery calibration" thing just an hoax? Been reading some lines around that disprove any effectiveness in doing so.
Hey guys, so the title says it all, my first charge from this device was just over 4 hours which is pretty good and it went all the way to nearly 6 hours screen on time and now its at 40% with stamina mode on, and screen on auto brightness with 2hours and 44 mins
So it might get to 3.5 hours before it dies which isnt great at all -.-
I use my phone pretty much the same every day, bit of Facebook twitter instagram etc
Do you guys have these problems? Battery life isn't bad, its just not consistent. Hopefully KitKat brings even better battery life ?

social media apps are really bad! Don't use them.. no seriously dont!! they constantly use CPU and connectivity hardware every minute, so your device probably isn't using deep sleeping during this time. I'm betting thats whats doing it
