The battery life is so good on the GS2 that with minimal use, it actually gains battery life. Attached for proof

[mrnd23]

Seriously this guy is not even worth replying to. he has been complaining about everything on this phone not realizing that he is in the minority. Everyone has the bad luck of receiving a bad piece. He has been adviced by multiple people he has a bad piece and should return it or exchange it. But all he does is keep posting the same complaint in different threads.
People who are facing issues please follow the many different suggestions given in this forum and if it doesnt work then try ti return or exchange ur phone.

Please see the attached video and you will easily witness the horrible battery drain that MY phone has.

FTFYT.

i'm in the same boat as the OP. reading around on XDA, it appears that my phone suffers from the android OS bug. my battery stats consistenly show my android os use to be upwards of 50% all the time. i take my phone off of the charger at 6:30am and will get the 20% battery notice by 11:30am. this has happened for the past 3 days with very light use while at work. luckily, i have only had the phone for 5 days so i am going to exchange it for another one tonight when i am off work.

What is this bug? I'm having intermittent hot phone/crazy drain issues in that it's cool as a cucumber or lasts quite well for a few days and then it goes nuts like it's doing now. I'm trying to rule out Live Wallpapers or rogue apps, but the one thing I was wondering was why Android OS was eating over 50% of the time, waaaaaaaaaaay over the amount the Display takes. How do I test for and rectify the bug? Thanks.

Ok this is the deal the problem with these phones is the OS bug hat drains the battery.. check out the Xda forums ..if you got to battery usage you will notice that the phone stays awake when it is supposed to be sleeping..why doesn't Samsung fix this? ? If so the battery would be great ..I mean Motorola and HTC seems to get updates out in no time but Samsung has this major issue of customer service

See the blank spots under Awake on the attached pic? This means my phone is asleep yeah? Take a screen shot and show us your solid blue bar when the screen is off.

[YBCold]

This thread its simply proof that the OP can't tell time!

Oh and as everyone else, I get 15 hours give or take every day!

You are wrong sir you phones awake time should match your screen time ..this simply proves my point that the awake is on more than the xcreen is which decreases battery life ..I got this from a known developer at xda ..thanks for proving my point

[Jerry Hildenbrand]

1. There is no such thing as an "Android OS" bug. Those percentages HAVE TO ADD UP TO 100. Even if you've only used 1% of your battery, things have used it, and will show up in the battery screen. Think for a minute.

2. Screen time can not = awake time, unless you have a magic phone that turns the screen on every time the phone pings the network. Screen time = the amount of time the screen was on. Awake time = the amount of time the phone was doing something. Things do not stop just because your screen went black.

3. Stop the personal attacks and links about the OP. Only warning you'll get. You may not like what the OP has to say, but he is allowed to say it as long as he isn't breaking the rules.

carry on fellas, but respect each other

It's only awake depending on what you're doing. If you're downloading something on the market and turn off the screen, it's obviously still going to be awake and not go into sleep mode.

No, I've actually completely debunked your point. Awake time will rarely, if ever match one's screen on time. The blocks of awake while my screen is off would be streaming audio via bluetooth during my drive to work. Yeah the screen can be off while playing audio (I know shocker). Not to mention the other things that wake the phone up briefly, like weather updates, email pushes, incoming texts, among other things.

Edit - I just noticed Jerry already beat me to it. Anyhoo, yeah what he said.

[eagle63]

Two of the biggest savers I found was to set my email polling to every 5 minutes rather than every minute and to set my screen timeout to 2 minutes.

Yikes, push email should be way more efficient than polling every 5 minutes. Are you sure that helped your battery? I'd try going to push and see what happens.

"That said, we have a zero tolerance policy toward individuals who come into the forums just to tear it apart. If you think the Epic 4G Touch sucks then try hanging out in your own forum instead. This forum is dedicated enthusiasts - not haters."

As Per Corey Streater

With all due respect, doesn't this apply? Many posters on here have helped and advised the OP about battery life in a respectable way even so much as recommending another type of phone. But yet continiously belittles the battery life of the E4GT. Not trying to start anything, just want to be clear of the rules, thanks!

so i exchanged my phone last night and re-installed everything that i had the phone i returned. this morning, i am experiencing similar battery drain. after 2hrs of very light use and the wifi turned off after about 45 minutes off of the charger, my battery percentage is down to 73%.




any suggestions to improve my battery life?

That is a boatload of awake time. You must have alot of apps syncing

I'm TMack, and I approve this message.

[madkaw]

I have been on facebook 3 times today, I have 4 email accts. one of them push sent a few texts to two different people and I still have this much battery.

MINE



YOURS


By the looks your graph signal strength is more then likely putting a pretty good dent in battery device appears awake the majority of the time.
Check to make sure PRL is up to date , If signal is weak at majority of your locations adjust settings for social feeds- twitter , facebook to manual update, disable gps, use push email or manual update on that as well

[stevedeezy]

i have 4 email accounts (2 push & 2 pull every 4hrs), facebook, twitter & photobucket to auto upload. nothing else.

If I were to guess, I'd say the problem is your cell signal. I see zero bars in one shot and one bar in another shot. I think your phone is constantly bouncing around trying to negotiate a better signal. This could be why your phone is not entering a deep sleep state as reflected in your "Awake" bar.

What do you guys think?

Edit - Erm i just noticed slingbox said the same thing above me. I'm definitely starting to think that the majority of people having battery problems are experiencing it because of a weak signal in their areas. I'm betting dguidry falls into this category but he won't post a damn screenshot.

[stevedeezy]

the thing is, with the phone i returned i got about 5hrs battery life at work with bad reception and about 6hrs at home. my signal at home is bad too, but i have an airave and use wifi. would i need to turn off my 3g data while on wifi to get a better picture of actual battery performace? hopefully this weekend i will have a better idea. my blackberry tour would easily get 20hrs with heavy email/text/fb use and my old tp2 would easily make it through my work day. i really like this phone but the battery life is really frustrating at the moment.

Has to be the issue i'm in the same boat here at work i get crappy signal it's always bouncing around between roaming and normal signal. But it's not sprints fault nor the phone on this one i work right next to communication towers that interfere with signal badly. But even at that i still get good battery life but yes it does drain a little bit more here than at home where i get great coverage.

My bust on edit.
I looked at my stats noticing steve had close to same time off charge as me so edit to post adding screen pic was needed to give him idea were I was coming from.

When it comes to dguidry,
No comment Ive preached enough on it.

[JayWill]

the thing is, with the phone i returned i got about 5hrs battery life at work with bad reception and about 6hrs at home. my signal at home is bad too, but i have an airave and use wifi. would i need to turn off my 3g data while on wifi to get a better picture of actual battery performace? hopefully this weekend i will have a better idea. my blackberry tour would easily get 20hrs with heavy email/text/fb use and my old tp2 would easily make it through my work day. i really like this phone but the battery life is really frustrating at the moment.

You could try to turn off 3G at home and just have wifi on and see what happens. Having a poor signal at home with an AirRave doesn't make any sense though. I really think it's a Samsung firmware issue that doesn't play nice with the configuration in your world, both at work and home it seems. All I can suggest at this point is to go back to Sprint support and see if there is anything they can do regarding your cell signal. Have your battery screen shots in hand and explain your observations in detail. It seems quite clear to me though that your battery problems are directly related to your cell signal, unless you re-installed an App that is adding to (or is) the problem. To check this, I'd uninstall most if not all of your market apps for a day and see what happens. If you're situation improves start installing Apps again, slowly, one by one, to try to find the culprit. Still, I doubt it's an App and likely signal related.

Good luck.

Its not so much about signal bouncing around yes it does effect battery life to a point but in Steve's case judging his screen shot major signal lows are taking place.
Notice brief period in signal graph were signals lost activity taking place in device awake graph. They line up something was taking place bets on social feed etc trying to update.
That will put major hit on battery life pretty fast.

i don't think what i typed came across correctly. i meant to say that i live in a poor reception area so i have to use an airave at home. the signal is great when connected to the airave. unfortunately, it's the 1st gen airave so 3g is not supported by it which really doesn't matter in terms of use since i use wifi at home. if the bad 3g connection is causing my battery drain at home, then i'll try turning it off to see if it improves.

Ahh I see. Maybe Sprint will send you an updated AirRave that supports 3G? This could keep you from having to turn off 3G if this turns out to be part of your battery problem at home.
