[Q] average or bad battery life? - Verizon Samsung Galaxy S III

thinking about getting my battery swapped if VZW lets me (have had the phone since 7/10).. if not, then get a new one. but before i go into the store, i wanted to see if you guys think this is normal battery life from these screenshots. i have GPS off, Google location on, and only my Google account (Gmail, contacts, calendar) is in sync. i'm running a rooted stock rom (debloated VZW and Samsung apps by me).
in addition, the back of my phone gets really hot during regular data use (web, Facebook, Instagram, Engadget and Verge apps, ESPN, etc.. no games), to the point where it's uncomfortable to hold. i've heard that there might be a batch of bad batteries for the earlier shipments, so i was wondering if mine might be one of them. thanks for any input.

Do you have 4G on at all times? I think my battery might be pretty bad too...I've been losing 10% every hour, so my phone pretty much lasts only 10-12 hours. I'm impressed by your 1 day battery life. Even if I have wifi only on and turn 4g off, I still only get 10% every hour. I think something might be wrong with my battery...I've factory reset it many times before too, wiping cache, and dalviks, I'm now on the stripped rooted stock.

that's not bad battery life. Especially sense it looks like you are not in great coverage area.

so you got 32 hours on your phone and you are wondering if that is bad?????
from what I understand, these phones tend to get warm after lots of screen on time. so I believe thats normal.
I would accept your great battery life and call it a night.

I get up to 8 hours with 4g on at all times with heavy use. Phone only gets warm when i got the charger in it

After using the Chrome app for 30 minutes straight, my phone doesn't get noticeably hot. I've also used the Engadget, Verge, and Facebook apps for 10+ minutes in a row, and it doesn't get hot. The only time I have seen it get hot is playing games and charging. Even then, it's not bad.

I would say you have a gold battery lol, I rarely even get 18 hours on my batter even when 12 hours of that is just standby/listening to music.

haven't had a proper measurement of the temp, but it feels like it does reach the upper 90s, and that's with light web browsing, so that's what worried me.
it's just that i see people who claim "heavy use" and get 4+ hours of screen time, which i found hard to believe, if they really are pushing the phone a lot, so i just thought maybe something's up with mine. thanks for all the input so far.

Looking at your battery consumption log, I'd say your battery life is pretty great.
Seeing as how your cell standby is 50%, you're either using a lot of 4G or you're in a crappy signal area. Or both. Haha.
Even if you buy a new battery, chances are that you won't get better battery life. Just charge the phone overnight and unplug in the morning. As a general rule of thumb, if you can squeeze 16 hours of usage out of your phone, you're doing pretty great.

yup, that seems pretty darn good to me. I get about the same 4G coverage as you with Verizon in my home 2-3 bars max (-100 to -120dBm), and I get ~14 hours before my phone is about to die. I also think I just use my phone a lot more than you lol. You only had 2.45 min of on screen time in a little over 1 day. I usually have close to that in the 12-14 hour days with my phone.

Agree with last two post...what else are you looking for looks good....

Should I ask for a new battery? 3 hours 30 minutes 30 min screen time and down to 67% battery.

I think what he's trying to point out is at 4 and a half minutes he's still at 100%, at 9 minutes he's down to 99%, at 13 minutes he's down to 98%, at 35 minutes he's down to 95% - and I think he's saying he expects his battery to be a lot better than this.
If you're checking your battery drain that often, I expect your screen was on a good percentage of that time, and yes, Display will use a good % of your battery. Look at your Battery Use, what's eating the most battery?
Oh, I wasn't looking at the battery icon. And now the other image shows up. I thought maybe that last one showed a huge drop. That would have indicated a bad battery.
homeslice976 is right. If you keep looking at it, it'll keep draining fast. Get a widget from the market that keeps track over several hours (or days) and look for trends there.
My problem is this, i leave my phone charge over night and when i get up in the morning i disconnect my charger.
but as soon as i disconnect my charger no more then 1 to 2 minutes i already lost 1% within 1 to 2 minutes of disconnecting the charger yes i understand if i keep checking it it will lose battery.
but as soon as i disconnect my charger i light up a cigarette and then go to my text messages, like i said 1 minute still smoking my cigarette it is already at 99% before i even open my text messages
this battery sucks big time, i had a MT4G and i have way better battery then this
Speaking of MT4G i am going to put it up for sale in the Sales section.
have a bunch of extras for it

This is true too. Play around with different radio/ril combinations, letting them settle in for a day or two before testing and see if you get any better results
Well moved from LeDroid to Virtuous Unity and battery looks a whole lot better and so does my wifi signal.
I have installed the Battery Monitor Widget so we will see what kind of results i get with it.
PS i am also using a Slim Extended Battery from Anker 1600mAh
had one with my MT4G with 1700mAh and it ran great
Your screen takes a lot out of the battery, end of story, not much you can do. I agree the battery life you originally posted was nutty. I had the same thing when I first starting using Coredroid. These links helped me knock out some of the other high battery drain issues and since haven't had too many problems..I do these anytime I flash a new rom and battery life has not been an issue. Hope everything on the new rom works out man!

I am still scratching my head. What is so wrong with the pics above? I don't dee it. Everything looks normal. Last pic shows 95% and awake time of 21:43. Do the math and that is over 400 minutes of wake time on a battery charge. Not to mention that you were doing something on your phone as you did switch wifi on for the last 20 minutes between pics.
You can't measure your gas mileage in a car by only driving 30 miles nor can you on your phone in only 30 minutes on a battery that probably isn't perfectly calibrated for the phone anyways.

Battery life

I'm looking to get a thunderbolt today and was wondering how has every ones battery life been. I'm making the switch from a ip4. So I hope doing the right thing. iOS is just getting so stale I want something new. So has is your battery life once u rooted and on the stock battery.

Thanks. If I can root n get at least 8 hours min. I'm fine. I'm just getting tired of the whole apple experience.
Thats easy, on most 2.1/3.0, aosp, overclocking not necessary, i can get 10-12 hours, n i dont care, i got 3 chargers. Its a good phone imo. U can run 3.5 with beats easy on this phone, but 2.1 with sound enhancer is just s good.

I can get around 7hrs on stock and about 16hrs on extended. Running ICS ROM

It depends on how u use it.
This is what I have left after few calls, browser, exchange+gmail+Facebook sync & 1 hr of Pandora
Only MIUI ROM so far I could achieve this. The other rom Ive tried is shiftao5p
Lastly if u are in 1-2 bars area, your battery will run out fast

I bought the rezound battery and noticed a pretty big difference. Also, I finally gave up sense roms and went with liquid smooth 3.2. Battery has been phenomenal. I can get through an entire day, even on 4G and moderate to heavy usage (screen on 4 hours) and not worry about battery until I'm in my bed messing around before I'm about to plug in and fall asleep.
Edit: here is me on wifi all day using up the battery with almost 4 hrs screen on time. On pure 3g 4G I'd be closer to 20-30 percent.
My GF has the extended battery and can go two days without charging (light use)
Loving the phone by by iPhone but anyway. Just rooted and messing around with these roms. Just don't know which one to stick with their are so many.
I'm on the stock rom and with light usage can easily get a full day out of a charge (I'm using the rezound battery now, but was similar with the stock battery). With very light usage, i can even make it overnight and through at least most of the next day on a full charge. Gaming, navigation, or a lot of downloading can run down the battery quickly. My so has an iphone4s and doesn't seem to get a ton better battery life.

Almost 5 hours of display on time. Mix in about 6 hours of sleeping but lots of Texting, rootz, xda, and Twitter. Imo kernel undervolted not overclocked, and 12 hours were in a bad signal area at my work in hospital I am talking -102 so battery could be better.
Sent from my ADR6400L using XDA App
I get around 8-10 hours on fairly regular use and towards 12 when I use it lightly. The biggest difference maker for me was not JuiceDefender or any battery saver program like that. It was using SetCPU once I rooted my phone and setting a profile up so when my screen is off, the processor drops to the ~200 MHz range. Definitely a must-have program for anyone who is rooted.
i keep everything running at max and carry a second battery pack with me... ill just swap them and am back to 100%... 2 full loads bring me through the day usually.
I suggest you to check this post and these batteries. This will solve any power issues you might have with your Tbolt
The rezound batteries work in the bolt also.

root + SetCPU
Pretzel pretty much hit the nail on the head. Once I rooted the phone I froze all of the stock bloatware, then installed SetCPU. Like Pretzel said, make it so when phone is asleep it only runs @ ~200mhz. Also do small things like turn screen brightness down and make backlight timeout 15 seconds.
Also, I cannot stress this enough
Your battery life will drastically change depending on what apps you have installed. When I download a new app I try to limit it to one at a time and watch my phone for the next few hours and see if my battery is running out quicker than usual. This has happened so many times to me where I install something with a 80% battery and then like 4 hours later its dead.
So with just the stock Rom, rooted, bloatware frozen, SetCPU, and about 60 battery friendly apps, I can get usually around 20 hours with light to moderate use.
The biggest difference on battery drain is if you have LTE enabled. Just download LTE OnOff and only turn it on when needed.

Battery

What kind of use are people getting out of their OneS batteries?
I've had my phone for just under a week and have run it through 3 or 4 full charge/discharge cycles.
Phone is running stock firmware. Last charge lasted ~36 hours with the screen using the most power.
I'd be interested to know what other people are seeing?
I get around 18 - 24 hours battery, depending on how i use it...
Battery life is epic on this phone Ive yet to see someone complain about it

Yup. Turn it off.
im have an imported international one s on att in nyc and i only get maybe 10-12 hours i use it fairly oftern but no videos or calls. i get no where near 24 or even 18 hours like i need.
12-20 hours.
That includes about 2 hours of off-screen streaming while commuting, 8-10 hours WiFi on, 2-4 hours games and surfing, 10-15 minutes calls and a dozen or so messages.
My last charge was at about 25% after 16 hours, and usage pattern as described. Screen is on auto brightness and consuming about 60%.
Anyone else? My battery life is exceptionally bad took the phone with me to the park 4hrs of listening to music with maybe an hours worth of web browsing and 30 of those minutes taking pictures the phone is dead

That doesn't strike me as exceptionally bad but rather merely less than average. An hour of web browsing is going to use a lot of battery in itself. Do you use the Beats enhancements too when listening to music? Bet that drains some battery.
its exceptionally bad in comparison to what everyone e else is reporting about this phone. and the battery is one of the reasons i chose this over the one x. my phone also keeps switching between h and 3g. im on ATT on an imported MAO
First charge and usage was; A few texts, 10-20 min of video, fair amount of browsing, installing lots of apps, tweaking and changing everything about, GPS, camera etc. and brightness was at 70-85% brightness for about 1-2 hours and dropped to 50% for the rest of the time, however, I didn't have my SIM in for the first hour of use (testing the mobile first to make sure it worked ok), wifi was on constantly as well.
Second charge and usage was; the same as above but a fair bit more browsing was done and a few games (angry birds and ROM emulators) and brightness was at 50% the entire time, plus this time the SIM was in for the entire time.

really good battery life, after a day of calls, bit of gaming, couple camera shots, with sync on, fb etc, battery is at 50% - 60% ,
I reckon i could get 2 days easy if i was economical, but 1 day easy with heavy use.
The screen will always have the highest usage so really battery stats are somewhat useless without sharing screen on time..

I highly, highly doubt that. Beats, correct me if I'm wrong, is just an "improvement" of the audio frequencies. An automagical DSP.
Without particularly trying to save power my battery is lasting 36 hours or so.
By far the biggest drain is the screen, currently at 65% of power drawn. Wifi is second with 7%. Considering that wifi has been on more or less constantly for the period this is pretty impressive.
I could probably push battery life to 2 days if I replaced live wallpaper with black background and reduced screen brightness generally. It's hard to know what else to do though.

There has to be some processing going on somewhere, that was my logic. Happy to stand corrected tho.
I got question regarding to battery and charging...
How it would affect battery, if I would charge it every day while driving 1h (it wont get fully charged if empty). Would it affect it badly in time?
i get about down to 30-35% at the end of the day with light web use, gmail, maybe a short phone call, and a bit of GPRS hunting when the signal is not that good. I just installed the power manager to see if there is any real use of it...
Mate...I've always disputed the battery andusic thing..your guaranteed to run out faster..I know it has that function and beats etc..but I pods or mp3 players do a much better job in every department and don't waste your phone battery. I'm getting a day and a half and I'm a fairly heavy user..I play the odd game. Text a lot to my wife lol..and surf the web. Its all about what your using...
One plus side..I use free beats earphones on my iPod and it sounds fing amazing.

I'm def a heavy user so I usually get between 12-14hrs out of my battery
Maybe the better pole would be screen time? I get at least 4 hours of on screen time.
I am on the stock ROM. Most of the time i can manage 1 - 3 hours of screen time and 8-12 hours of battery life. Its not terrible but my 2 year old iPhone 3GS seemed to manage better when playing music. I use my phone at work and listen to music for about 6 hours a day with power amp. I also live in a heavy LTE area so most of the time I am on LTE and no wifi which just kills the battery. No power saving either.

Moderate use 14 to 16 hours. I usually kill it while in bed playing with it.
Having said that I find heavy camera usage will kill it quite fast and I will have to recharge mid day. It feels abnormally fast but hard to say for sure.
Wow... how are some of the moderate users getting more than 14 hrs? When I don't use it much I get 24 hrs easy, using JuiceDefender and FreeGS ROM.. If I use it moderately it gets ~12, if I stream music from Pandora for around 4 hours it lasts <10

And yes, I take the subway (to get to work) everyday and notice my battery drains quite rapidely afterwards (7h am to 16h pm without any usage, mainly standby). On weekends, my battery seems to do much better (15-20h moderate usage).
Today I was at 60% at 12h32pm and then 46% at 13h42 without any usage (lte and wifi on, stand by). I rebooted my SG3 at 13h55 while I was at 43%, since then much better, I'm at 40% at 15h12pm.
Anybody experiencing something similar ??

Best battery life on any of my Samsung phones.
Light use, been out with friends. But did a bit of navagation with maps, some forum browsing and quite a bit of texting. But I have to say, much better battery life than the SGS2.:thumbup:
Best battery life of all my Samsung phones so far.
Lasts all day, even with leaving data and WiFi on.
Have to say I am pretty impressed, given battery life of the SGS2 and SGS1.
I am very impressed with the battery life on the phone! I work in an area with little to no service so my phone searches for signal all day. I usually spend about 10 hours at work a day and with moderate use I have enough battery to last all day. If I turn WiFi on phone stops searching and get even better battery life. This is the best phone I have had for battery life. I'm on t-mobile.

Battery Life All Over The Place?

Hey guys,
So its been about 3 week since I've had the SG3 and I love it, everything except the battery life.
My battery life varies alot day from day which is really weird.
I have LTE on (but i'm either at the office or home, so wifi is usually connected instead), background sync on, GPS off, Bluetooth off,NFC off, about 25% brightness and power saver mode on at all times.
Somehow it seems that when in standby and not in use it drains more battery than when in use and using LTE instead of WiFi.
For example today, full charge since 8am, and I'm at 38%..(It's only 3:30). This is being on WiFi for 90% of that time and only occasionally texting and checking twitter/facebook/email.
Your experiences?
My GS3 gets great battery life (well, at least compared to my old D2G lol...). 5 hours and 20minutes off the charger, and I'm at 65%. But mind you, my screen has been on for nearly two hours of that, and I've been on the internet/in a call for 30mins of that, and texting for the remainder. People seem to be getting mixed results as far as battery, it's just one of those quirks. There's actually already a thread going about battery life.

The screens only been on for 54 minutes of the 8 hours 11 minutes the phones been off the charger.
For some reason when I'm about and using LTE and constantly calling/txting/tweeting and what not I have better battery life than sitting at home or at the office on wifi and using the phone less.
Yeah my battery life is also very inconsistent. Just sitting at home on my desk it will sometimes drop only a few 3% over several hours and sometimes it will drop 35%. I haven't been able to figure out any contributing factors yet. I do get terrible cell reception at home but I keep it on wifi, and the above examples are when the phone is sitting in the same place.
consistantly 20 hours with 4 hours screen time on and usually with still 25-30% battery left. Always on 4G never on wifi. Never have battery saver on.
Only thing I do have is a setcpu profile for screen off that severely limits the cpu.

I have only had my S3 for 2 weeks, but I have been able to easily get a full day out of the battery. I typically have about 1 hour talk time, 2-3 hours wifi and maybe an hour of 4G web surfing.
I do have the battery saver mode on (not sure how much of a difference it makes) and I generally don't charge during the day.
Mine is also very inconsistent. When it is just in my pocket it lasts a really long time 12-18 hours, but if I'm doing something simple like listening to music with the screen off, from the sd card it dies in half that time.
When I'm home and connected to WiFi I have been turning off mobile data. Whenever I wake my phone up from sleep it notifies me at the bottom of the screen "connected to my wifi network". So I don't know if the WiFi goes off in sleep mode, if that's the case then it normally would be connecting in and out of 3g/4g hadn't I turned off mobile data.
I've also been very religious about fully closing apps instead of just hitting the home button. Also using task manager to clear out running processes and ram
Both of these seemed to help out tremendously
