[Q] Real World Battery Life

Fellow MT4GS users,
How is your battery lasting you? I'm coming from a MT4G, even though I eventually modded it, and it I used to get at least a full day and have to charge that night at the worst unless I really heavily used it.
My MT4GS has been lasting me half a day or so before I get into the yellow/red and I'm usually charging before the sun goes down.
My main culprit according to the built in battery indicator is display at 65% (I'm on automatic brightness)
Just over 10 hours today for me before I had to charge.
ps- Anyone know how to remove the annoying low power notifications? I'm getting two pop ups in a row.

Yeah mine generally lasts about 14 hours at moderate usage, but it's only been 2 days, and I remember when I got the MyTouch 4G it died on me while I was still at work and then after a week or so it got much better...

Yeah, I can agree with you there I think my MT4G was a little wonky the first week or so. We'll see how it goes.

Only lasting 6 hours yesterday ....

My battery lasted about 33 hours. After the 1st full charge. So way better than my other phones have done. This wasnt heavy usage though. No videos or music just a few calls, lots of emails and some web browsing.
One problem I am having is low call volume. My videos and music are perfectly loud, just the call volume sucks.

Well make sure, your phones screen brightness is on low. Also make sure wifi,gps,bluetooth are off. Also make sure you kill some of the apps you ran on a task manager. just gotta find ways to keep the battery life up.

Well when I first got the phone, I didnt charge it until it was almost dead. Then fully charged it.
Also I turned off GPS, WiFi ect. I also use task manager to kill background programs that I don't need or want running.
We will see if the battery life goes down after a few weeks. Sometimes they take time to normalize.

Oh what task you ended and what task manger you used?

I appreciate the help but the logic is off. This is the latest ..and i stress smartttphone. It is supsupposed to be used as such. Bluetooth ..4g..music...video calling..maps..etc.. if u use of of these features six hours it will last. If you use them all try maybe 4 hours. Plus those boxes are annoying when the batterly is low. This phone has got to be rooted.

I'm gonna have to agree with that one, that's pretty much no different than saying buy a car but don't drive it so you can save gas lol

I have gotten to around 12 hours or more now. Still moderate overall but heavier browser usage.
I do not kill tasks or turn off wifi, gps or anything. My brightness is auto.
I uninstalled the recent maps update because I saw where G2 users seem to think the recent update is draining their battery so I wondered if it could maybe be causing issues here too.
Anyways my battery life has gotten into the acceptable range and that was all I really did other than have more days to monitor it.

Some technical specs on the battery:
Model: BG58100
Rating: 3.7V DC
Charge Capacity: 1520mAh

This appears to be the same battery that is in the Sensation 4G according to Google.
For us this is good because Ebay and Amazon are already flooded with replacement batteries.
We need to find a higher capacity mAh battery but with the same size as to not make us have to get a replacement back. This shouldn't be that hard.
My old phone has a smaller battery with a higher mAh capacity so the battery in the myTouch 4G Slide is an utter disappointment. They could have easily produced a 3000 mAh battery for this beast of a phone.
Edit: Found a 1900 mAh battery for only 9.99.

Screen is on the least bright setting. I'm an ex blackberry user and dont even have one app. I could care less about apps. I'm charging every 5 hours and thats sometimes from just it sitting around/ not even using the phone. The thing better get it's act together. I'm starting to like the keyboard too but I'm up at 5am and if im charging at noon that's terrible. Especially with minimal use.

There must be something wrong. Mine lasts about that long playing videos and games, messing with the camera, web browsing etc..

As I posted in my other thread, battery sucks on this phone. I had to keep wifi off all the day to keep it from dying by 6pm. Funny how 4g speed is so bad in nyc that wifi is the only other option to do something meaningful.

Weird I live in small city and 4G is crazy fast. When I get to a big city like Baltimore, Maryland the 4G was slow. My thoughts are there too many people on the 4G network. T-Mobile did promised us double the 4G speed and they need more Towers too.

For the first couple days, my battery life was awful. I'd be getting low-bat notifications when I got home from an 8-hour day at work.
But of course that's always the case with new phones that haven't even had the settings tweaked...
- Placed a Wifi toggle widget on the homepage and turn it off every day after leaving home for work in the morning.
- Ensured certain programs and updates were not running in the background automatically:
~ Turned off Autosync on accounts (manual only)
~ Turned off autoupdates for weather
~ No Bluetooth, GPS, Wifi, unless turned on for a specific reason
~ Enabled power efficiency and power saver modes (30%)
~ Disabled Always-on data connection
~ Disabled auto-updates in various apps (Friendcaster, IM+ Pro, etc.)
- Turned the screen off when not in use
Today I'm at 40% after 14 hours of mixed use. I'd say that's DAMN good.
By the way, for those seeing the whole "Autosync off" thing and thinking that you can't do it, just do it. I don't get my work email or personal email on my phone unless I tell it to and it's utterly awesome. Less stress. Less looking at my phone constantly. It feels free and just plain great. And I used to be superconnected 24/7 syncing every 5 minutes (if push wasn't available).

Display uses most of my battery.

So I've acquired an HTC Sensation and have unlocked, rooted, and installed a few ROMs so far. Stock, CM7.1, and Android Revolution HD. That last one is the one I'm on.
My battery life sucks. Whereas my Blackberry Bold 9700 would go one to two days with constant, heavy usage, this phone gets about 4 to 6 hours. My battery graph says that Display is using 80% to 90% of my battery. I've turned off auto-adjust and set the brightness to minimum, it hasn't helped. Am I ****ed?
I've tried other things, underclocked to 1Ghz, different ROMs, battery calibration, no HTC Sense account, no friendstream, disabled background data and autosync. I've tried everything, and yet the display is totally destroying my battery. Keep in mind too, I mentioned the Blackberry, but I've had Android experience before. I'm not a total noob, and I'm not a pro.
EDIT: If you've got semi-****ty battery, check my last post on page 2. It might help ya out. http://forum.xda-developers.com/showpost.php?p=19062683&postcount=20

That's an LCD screen for you. It will always be the biggest power consumer of this phone. I believe that in general, the screen will always be the biggest power consumer of a phone, but LCD is especially bad. It doesn't help that the Sensation has an average-sized battery either.
That said, I can't believe your battery life is that bad, considering you've underclocked, tried different ROMs, calibrated the battery (although I've heard that this can actually decrease batt life), and disabled background data. Make sure you have matching radio + ril in case you haven't yet. I just can't believe that if you're doing all those battery saving tricks at the same time that your batt life would still be bad. Or did you try those things by themselves? You should try several things at once, but I'm assuming you already have.
LCD screen tech really needs to hit the grave. I like qHD resolution, but otherwise I hate the Sensation's screen. I don't get why so many Sensation owners think it's a good screen. LCD is absolutely worthless outside - I turn brightness all the way up and I can still hardly see it. I don't care if SAMOLED has oversaturated colors - as long as it's usable in any conditions I think it's better. Not only is SAMOLED much brighter and usable, it is much more power efficient than LCD. Honestly the screen alone of the Galaxy Nexus is making me consider it just because I hate the Sensation's screen that much (as well as other things about this phone).

I'm doing them all at once. I flashed the radio that mike (author of the ROM I'm using) suggested because he said the RIL file(s) are built in.
I'll post a battery stats screen cap when I can, but I don't have the means to do so right now.

Edit: There it is. Normally, I don't partial charge, but I had to take it off briefly a few minutes ago. As you can see, it was hitting critical levels around 5 hours in before I threw it back on the charger. The line drops steadily usually when the display is being used.
Here's the shot that claims Display is the culprit.

I feel like android never goes into detail as to how much being on 4G drains your batteries. If you switch to EDGE (2G) only, you could see an improvement in battery life. You can get to it from Settings>Wireless Networks>Mobile Data.
If that doesn't work out for you, consider trying out Juice Defender on the market, it's helped me extend my battery life a considerable amount. It does nothing while you're using your phone, but when your screen is off, it'll disable mobile data, and every 15 min (or 30, you could change this in settings), the phone will enable mobile data for a minute so Facebook/Twitter/Messenging Apps can sync.
Aside from that, you can try turning down the brightness levels.
If you're willing to shell out a little cash, your next option would be to cop an Anker battery from eBay or Amazon. This would help the most, imo.

I have tried many things but so far the biggest thing to affect my battery life is disabling bluetooth. That alone takes about 2% per hour of battery life even if I never use it. My usage is light with some games, mail, and texting. Included is a snapshot of today's random usage. I don't know why but my display isn't listed in the snapshot.
One thing I would check is the spare parts app that hopefully is included in android. Look at the battery history->other usage->since last unplugged. Specifically the percentage of running. Mines says running is 12%, screen on is 4%, wifi on is 83%. If your phone is 100% running, then it is never going to sleep.

Is the Sensation a 4G device? if so, which carrier?

Not real 4G, max speed 14.4 mbps where available for TMOUS.

Ur comparing the sensation to a bb 9700? 9700 is not dual core or a 4.3 inch screen. Androids typically have the worst battery life when compared to iPhones and blackberrys. Also HTC phones usually have the worst battery life out of all the android phones.
How long have u had ur phone? Have u gone through at least 5 charging cycles? Did u calibrate ur battery after flashing new roms?

The other day I got this...maybe it makes you feel better...(1900mAh Anker Battery)

I have the same problem, more or less.
I had a great improvement installing "juice defender", this app cutting off the 3g as soon as the screen is off, putting it on once every hour to chek mail etc.
try it.
it's an improvement, but my battery drain remain awful. I had a HTC HD2, and was used to 4-6 ma, now, if it's under 80, i'm happy...

Turn the brightness down. I only use auto brightness in the daylight. I used a app called dimmer to turn the brightness down to 10. The minimum setting the phone will allow is 30 so dimmer turns it down more. The dimmer app is nice it switches brightness down to 10 and the next click sets it back, so I have it switch between auto and 10. Full brightness will kill your battery fast.

I never directly compared them, I'm just sharing my past experiences. I never expected the sensation to come even close in battery life.
anyhow, ill try juice defender and my Bluetooth and brightness are off and set to low. it just sucks cause I seem to only lose a lot when the screen is on, but I don't want to blame S-LCD because this seems to only affect a small percentage of users.
worst case scenario, ill buy a new battery. thanks everyone for taking a look, please excuse the grammar, on my sensation right now

@OP... don't worry about battery life. I am in the same scene as you are...
Running an HD game would drain by battery in 2 to 3 hrs with lowest brightness and everything off.. My only problem is low network signal...
if you start using your mobile as laptop like playing games etc then you get as much time as a laptop gives u... But if you use it as a phone, out will do all say..
So either change device or line with it..

In Android Revolution the kernel spends the battery. You can flash the bricked kernel and you will see the battery life in normal use under 20 hours. You can find it under android development for sensation here in xda. I flashed yesterday and with wifi on and all sync on I have 45%. 12 hours from the last charge.

I will most definitely try this when I return from work. I may have to flash cyanogenmod, which seems to give me slightly better life. is the stock AR HD kernel really that bad?
edit: okay I went ahead and flashed the bricked kernel while at work. hope it helps, but I lost 10% battery to do it and I'm down to 20% left. we'll see how it does.

From what I read we have a new faux kernel. You can check it after bricked.

Hey guys. Small update.
I am recalibrating the battery, again, yet something special is happening this time. I ran the phone down and it played a 1080p video on max brightness with wifi, bluetooth, gps, background data all on. It played the video for 15 to 20 minutes while sitting at 0%! Now, I'm currently recharging it and best part, it's been at 100% and still charging, orange LED and all, for about 40 minutes now. Considering my charger charges at .75A an hour, thats something like .50ish A, or 500mAH that I didn't have before. That could explain my pathetic battery life. Imagine if it charges at 100% for an hour! That's 750 mAH that I lost due to bad calibration, half my battery!
Hopefully with a few more cycles, and some good luck, my battery meter will correct itself and I'll see regular battery life!
edit: Two hours In, I'm overclocked to 1.5ghz, have max brightness, wifi, GPS, Bluetooth all on. background data and auto sync enabled. the screen has been on almost the entire time. current battery? 40%! that's with constant interaction, at times, I was playing games and listening to music at the same time. I mean Im using this phone to the max and its performing incredibly.
in real life, I will underclock to 1 or 1.2ghz (still an underclock since the system is clocked at 1.5ghz default) and wont have the screen on the entire time, so I shouldn't have a hard time making it through a day with moderate to heavy use I also never really use BT and wifi is a rarity. background data will likely stay enabled, but we'll see.
please excuse grammar, on the sensation right now and I just gave up the BB 9700 keyboard just two days ago, one of the only good things about that phone!
edit2: okay so I ran down the phone. it shut down just minutes before the 3 hour mark. this is very exciting because my battery barely decreases while the screen is off. on Max brightness and wifi/GPS/Bluetooth/4G on, and the screen on for all but about 10 minutes, I got about 3 hours. this is exceptional. ill do a real world test tomorrow and report back, but things are looking up. currently, brightness is set to auto, wifi is off, GPS and Bluetooth are off, processor is clocked at 1.2ghz. very excited that this one calibration actually did something!
also, I consider HSPA+ to be 4G cause its about 10 times faster than any 3G out there and it's actually been official for a while.
www.phonearena.com/news/ITU-says-LTE-WiMax-and-HSPA--are-now-officially-4G_id15435
Edit3: It helped, but I'll be buying a Chichitech battery, ordering it tomorrow. 1900mAh better make a difference.

So its been a few days, but here's what I did to get acceptable battery - all at once:
Flash a Cyanogenmod rom, HyperSensation, the other one, Selfkang or whatever is a MAJOR battery destroyer for me. Any kernel, any clock speed, I'd lose 5 to 10% an hour just idling. I lost 15% alone playing 4 mp3s through my AUX cable. Not saying it's like this for everyone, but it was for me.
Flashed Faux's kernel, Joe's RCU from his thread.
Underclocked to 1.08Ghz while the screen is on, 540Mhz while the screen is off.
Undervolted the processor using FauxClock to -37.5mV, might go even lower if it's stable.
Ordered a 1900mAh ChiChiTech battery from Amazon, http://www.amazon.com/CHICHITEC-T-mobile-Sensation-Cellphone-Battery/dp/B0057US9YW - whether or not it's 1900mAh doesn't really apply, but what does is that I instantly got 20% more and I'm not even done conditioning. It's only 23 bucks, two for thirty. I was so anxious to try to get a battery that I next-dayed it for 17 bucks.
I'm a moderate to heavy user, I used some wifi hotspot today, automatic brightness for the display, background data and auto-sync, listening to standup comedy mp3s for 1.5 to 5 hours a day, web for probably 30 minutes to an hour a day, and today specifically, 45 minutes of Legends of Yore (fun rogue-like!) and 15 minutes of Age of Zombies.
Only two thirds of my battery used and I've been off the charger for 13 hours. My old battery would have given out about 6 hours ago, and that's if I cut my activity in half.
Anyhow, problem's solved, but I figured it'd be a good read for anyone in a similar boat.

Skyrocket Battery Life? HORRIBLE

So I've had this phone for a week now. Its a nice upgrade from my infuse 4g. But the battery life is killing me. I've tried every Tom.available specifically for the skyrocket and even the one kernel in the dev section. My brightness is 15% and I use juice defender set to every 30 min. I listen to Pandora for an hour and it drops 20%. Yesterday it was dead in 6 hours. Its to the point where I'm seriously considering going back to my infuse. Has anyone else had issues?

Currently have juice defender, 0.2 kernel (didnt update and probably wont for now), and a few apps frozen by Titanium Backup. If I hardly touch the phone, it would last 41 hours. With medium usage, (Wifi, web browse, using poweramp for some time, calls, emails, etc) It would easily last my entire day.

What apps did you freeze?

I have JuiceDefender Ultimate set to balanced, I have only the clock widget running, I have GPS running continuously, (I use Wifi occassionally), I have screen set to about 50% and with very normal usage, the battery is at about 20-25%. I have a good number of email accounts and they are polled constantly, notifications are normal (phone settings), I use the Market app and the browser a number of times a day and I hear the occasional podcast. By the way, listening a podcast for about 1 hour (I use BeyondPod and earphones) results in minimal battery usage (about 2% for an hour or so).
So, I have to say that I am quite happy with battery life.

I know what you mean.
I had a stock skyrocket running in a weak LTE market in New Orleans and it would last like 8 hrs then I rooted and frooze all the bloat ware and de-installed a lot of app that were always using the web. I manually set my screen brightness. And changed the launcher to go launcher. Getting 18-20 hrs lots of moderate usage lte and all.

Yea something is wrong. I don't even use juice defender yet my phone last all day wit like 20% when I get home at 9. I use it to talk at least 3-4 and moderate usage for internet and am in wifi a lot. Youtube umm often..Defective maybe??

Battery life is amazing for me with heavy usage. Just make sure when your not using lte to turn it off and use wifi as much as possible.

How do you turn off LTE?

look in settings, about phone, battery and see what is using all your battery. Battery life is very good on the stock ROM, rooted or not. You might also want to install Traffic Monitor and set it up for your billing cycle properly. Then watch for a few days to see what apps are using data. I do not recommend turning off LTE.
BTW there is already a very good Freeze list of Apps...

I was also having very low battery times on my SR to the point it was draining about 5% every half hour. I checked everything and everything was set properly. Yesterday was ready to pack it up to exchange it and thought I try restoring the phone. After restoring it, I now get excellent battery life. I'm getting about 1% battery drop every hour. Today tested throughout the day and listened to some music, some web browsing, a few FB posting, a call for 20 minutes and have 95% battery life left.

I've had pretty bad battery life here in the DC area (LTE is available here). It'll last about 6-7 hours with very mild use. Maybe I should restore it?
What did you do @ElCamino to reset it? Maybe I'll try that too (though I'll hate having to set it back up again).
Also, I turned juice defender back on today, and I've noticed that it seems to be keeping the device "Awake" even when the screen is off. I have it on "balanced." Can anyone give me a little advice on setting it up correctly. I can't seem to get it to let me open more granular settings.

So I am starting to wonder if there are some defective units being shipped. My wife and I both have a Skyrocket. Mine is great, been using it for 13.5 hours today on medium usage. I currently have 63% battery life left. I am completely stock, no juice defender or any other like programs. I even had No-LED installed and used my flashlight app for about 5 solid minutes.
My wife on the other hand has the exact same setup as I do. She complains she barely gets through half a day with medium usage. I charged up her phone earlier today. 7 hours ago I took it off the charger. She has used it with very light usage in that time and it is down to 60% already. When I say light usage I mean sitting on the table for at least 6.5 of those hours. Often she charges it up while watching TV at night.

I've had pretty bad battery life here in the DC area (LTE is available here). It'll last about 6-7 hours with very mild use. Maybe I should restore it?
What did you do @ElCamino to reset it? Maybe I'll try that too (though I'll hate having to set it back up again).
Also, I turned juice defender back on today, and I've noticed that it seems to be keeping the device "Awake" even when the screen is off. I have it on "balanced." Can anyone give me a little advice on setting it up correctly. I can't seem to get it to let me open more granular settings.

@jslanger I went to settings>privacy> and choose Factory Reset. Yes i know that you have to reinstall and setup the phone, but I am glad I did. Battery life has been great. I'm not in a LTE area but like mentioned battery was draining quick before.
Also I wouldn't recommend you use a back to restore, just in case that something with OS setup from Samsung causing this.

So I am starting to wonder if there are some defective units being shipped. My wife and I both have a Skyrocket. Mine is great, been using it for 13.5 hours today on medium usage. I currently have 63% battery life left. I am completely stock, no juice defender or any other like programs. I even had No-LED installed and used my flashlight app for about 5 solid minutes.
My wife on the other hand has the exact same setup as I do. She complains she barely gets through half a day with medium usage. I charged up her phone earlier today. 7 hours ago I took it off the charger. She has used it with very light usage in that time and it is down to 60% already. When I say light usage I mean sitting on the table for at least 6.5 of those hours. Often she charges it up while watching TV at night. Takes it off the charger when she goes to bed and by morning the batter is at least half drained.

Try the Factory Restore and see if that helps. It helped me.

I have had my phone off the power since 10 am sunday and used moderately with calls and few games lots of texting and FB syncing. And now at 3:05 pm monday 27% with texting and FB no games and calls.

look in settings, about phone, battery and see what is using all your battery. Battery life is very good on the stock ROM, rooted or not. You might also want to install Traffic Monitor and set it up for your billing cycle properly. Then watch for a few days to see what apps are using data. I do not recommend turning off LTE.
BTW there is already a very good Freeze list of Apps...

Anyway you could link to the list and also let me know what the app is that does the freezing. Mine is rooted but i'm kinda new to this.

Search for Titanium Backup in the Android Market. You will have to check and see if it requires the pro version to freeze apps.

just to help you guys possibly, i moved some APPS to my SD card last night, at work i noticed mediaserver was second in my battery list and my phone was draining faster than normal
after moving the apps back to the phones internal, the drain seemed to stop, i also wiped the sd card just to be safe as i usually stream pandora anyways , but just another option to look out for

Weird....
So I've been closely following my battery life because it kind of sucks.
I had great battery life at home while on wifi over the weekend...about 18 hours no problem. I recharged it today at work, and was not getting great life during the day while on LTE/4G
Got home, turned on wifi, and the battery drain completely leveled out. I also noticed that while on cellular, the "Awake" bar is solid. As soon as I'm on wifi, it was able to not be continuously awake.
Not sure if anyone can comment on the reasons that this would be, but usually its the OPPOSITE. I really dunno why this would be.
Any help is appreciated!

Here is my battery life. Rooted and haven't froze any of the apps yet.
I know i

[Q] does this look normal for Battery use?

So I just got this thing as an alternate exchange for the mytouch 4g and I like the phone .. but the battery on this one suuucks. It drops ABOUT 10% an hour and I havent really used the phone much at all.
When I look at the battery stats it looks weird to me .. the screen is always the lowest thing using the power by a lot, and its ALWAYS the system idle and standby that use the most battery by far .. which seems kinda backwards to me .. I dont know .. so thats why im posting this here.
My battery seems to only last bout 10 hours or so with light usage... which is way worse than any other phone I have had which is the mytouch 4g and the Galaxy S II.
Today I have sent 2 sms and recieved 2 sms and have no calls at all. I did check facebook Three times to see some posts so a few minutes there. The screenshot is from today and Im already under 50%. I havent turned on the wi-fi. GPS is off and I do not use bluetooth at all. I also have the screen brightness at 25% and this is with a normal clock speed as well. I have turned on the screen several times just to look at stuff... but that doesnt explain the 3% screen usage and the freaking 48% of standby and idle.
someone thought battery .. but I dont think so with how the phone is saying that the usage is spread out. Does the screen on this phone really use that little power and the idle and standy drain the battery like that???

Each person's phone will have different statistics. Different ROMs and kernels will give different results and the kind and number of running apps. Those percentages don't indicate the amount of drain (current) each one is using from the battery. Are you using a battery management app to keep the battery drainage minimum?

I am not using anything like jusice defender .. I do kill the services in the background a few times a day with system panel app. i am running CM 7 on here .. so im sure a lot of others are as well.
since im new to the phone im not sure if this is normal or not for it to die this past without it really being used much. system panel did say that a few apps used battery .. but one was at like 8% and the others were well below that.

Try using Weapon 3 with Faux123 kernel.

Got to remember it is dual core and will use more battery power.

My current stats after only 11 hours of use:
Battery level: 12%
Cell standby: 34%
Phone Idle: 33%
Wi-Fi: 31%
Wi-Fi Calling: 3%
Display: 2%
Haven't used my phone for most of the day. I sent 3 or 4 text messages, and was only away from my apartment for 30 minutes. BUT, this is shortest amount of battery i've ever seen this thing suck up. I usually range between 16 to almost a whole day before having to plug in, and that's with my being away from the house and browsing on data for about an hour and a half (2 breaks and my lunch).
I think the phone has it's own mood swings, lol. At least it charges pretty quickly!

I have had lots of variability in battery life between different copies of the g2x and different roms. I have tried almost all the roms on these forums.
My personal experience is that there are good and bad versions of the g2x out there. The bad ones tend to overheat and shutdown. These naturally have poor battery life.
Also, I have noticed that the g2x does not handle areas of poor mobile reception well. It tends to drain battery and overheat in these instances as well.
Finally, I have found LG 2.3.4 based Tsugi (with stock kernel) is far and away best for battery life. Might be improved code from LG, might be the baked it toggle2g app... but I am very happy with this phone under Tsugi.

oh wow .. i will have to try some different ROMs then it sounds like and see if that helps

absolutely .. but I also have a Galaxy S II and it uses nowhere near the battery as this thing does at all .. and usually the display is what uses the most power and idle and stanby are what uses the least .. and the G2X is opposite of that . which doesnt make sense to me cuz if its idle the the screen is off and I have it underclocked with screen off .. soo I dont know why that would be using so much battery.

see yours looks like mine does . except I didnt have the wi-fi on .. so maybe this is typical for this phone to use so much battery when its not doing anything. i just cant imagine how the screen uses so little battery though and the idle so much.

I could be wrong but I think the % is based on the time and not the battery.
Cell Standby 34% of the 11 hours = 3.74 hours on not 34% of the battery. If your total all your numbers together it would be 103%.

You are correct GTWalling. Those figures are based on how much time each event is using the battery, NOT How much battery each event is using.

If you knew how much current (milliamps) each event/process is using then you could calculate how much of the battery's capacity it uses by taking the total time X percent of time battery used X milliamps. The battery is supposedly 1500 milliamp-hours. milliamps used/1500 milliamps X 100% = percentage of battery used by that event/process.

Hmmm interesting stuff here ... Thanks for the replies.
Sooooo if that's not how much battery they are using then is there a real good app to see what apps or system apps are using the battery?
I have looked at the market but none looked very good.thanks

[Verizon] you loving or hating your battery life? LOVING mine!

I am LOVING my battery life!!! I keep seeing people gating on the longevity but im not seeing it. Im not rooted yet and im still getting 18+ hours on an everyday basis.
Also seeing people talk about how their phone doesnt stay on 100%. My TB had that issue but my S3 will stay on 100% for an hour after being unplugged if i dont touch it. I havent found one thing to complain about with this device yet.
All notifications turned off except handcent sms. When im at home in the morning or evening i keep screen at 1% and 25% during the day. 45% if outside.
I have 4g turned off and 3g forced with "phone info" app. The only thing i cant figure out with this phone is turning off/on background data. After turning it back on after turning it off, my email errors out even though data is certainly on. So for now i just leave background data on. Im sure battery life would be even more impressive if i was able to figure this little bug out.
You loving or hating your battery life?

Mine is pretty ridiculous compared to the Nexus. I'm easily getting over 2.5 hours screen time, and yesterday I was at 61% after 12 hours and an hour of screen time.
Edit: Currently at 90% after 5 hours off the charger today. Not much screen time, though.

I'm not very impressed with battery life...yet. I think I've got some sort of issue going on. My "Android System" entry is very high. Sometimes higher than screen. Anyone have any ideas as to what my problem is? Another note is that my phone is always warm to the touch, even with screen off, and nothing (intentionally) happening in the background.

Do you mind posting a SS of your settings on the Phone Info app?

My Verizon S3 is horrible. Even after a full wipe (x3) and custom clean rom and frozen apps that run as services.. Just sitting on my desk, it's bad.. 6 hours into the day and i'm down to 60%. Awesome phone, Samsung!

I'm very impressed with my battery life. It is such a leap from my Inc. Yesterday I got 15 1/2 hours with 5 hours screen time! It was a really good day. Usually get around 12+ with around 4 screen time. Mine also stays on 100% for a little bit after charging. I have yet to root, and haven't really changed to many settings to help with battery life. So I'm pretty sure it can do even better!

My battery life has been nothing short of amazing (my wife too, who got her SGS3 the same day as me). I haven't rooted, so just disabled a few apps and did some minor tuning of settings... the best example I can give is this past Saturday...
We drove 600 miles on a round-trip through three different states, a mixture of back roads, typical suburban areas and through two major cities, so in other words a good mix of connectivity, some roaming for sure included... I used the phone a fair bit throughout the day because we went to a family gathering, so there were quite a few pictures being taken with it and people playing with the "new hotness" of course... I played games for a bit on the ride (err, when my wife was driving at the time!), checked mail, Twitter and Facebook probably once or twice an hour on average (I know, I have no life), a little web surfing to look stuff up, played with S Voice for a few minutes, streamed some Pandora for a while and used GPS for a few minutes here and there. The WHOLE DAY I had wi-fi, GPS, mobile data, NFC and background sync turned on (only things turned off were bluetooth and LTE).
Phone came off the charger at 8am with 100% charge... By 9pm that night I JUST hit 50%! And by the time I finally went to bed at around 2am it was at right around 25% (because I read for an hour or so with it before falling asleep).
That, to me, is pretty freakin' phenomenal! The only time I ever saw comparable battery life was my Epic with the big, fat extended battery. And, again, this is 100% stock with minimal tuning and I'm not sacrificing any feature that I care anything about (I don't have all the motion gestures or face unlock or stay turned on for example because I can live without those just fine). I DO ensure that the apps I have installed are all completely well-behaved and I turn all off but a very small handful of push notifications, that's the sort of "tuning" I'm talking about.
So yeah, count me as completely ecstatic about my SGS3 battery life for sure

Im NOT rooted or anything and running everything stock and every single day I have managed to get at the very least 4 hours of screen on time. I have brightness on 50% with wifi on and no airplane mode. Battery is amazing on this phone and I could not be loving it anymore.

That's odd. No notifications running in the background or anything? I've been getting awesome battery life on mine.

So it seems from this thread, non-rooted users are getting better battery over rooted?

my gf's verizon (100% stock) gs3 is ridiculous... 14 hours with 53% left and 2.5 hours of screen time. compared to my AT&T GS3 which is at the same level after 6 hours and 2 hours of screen.
a lot of it may also have to do with what networks you're on; i.e. my gf was on wifi all day whereas i was at work in/out of LTE/HSPA+.

in this thread it seems that way but read thru the other 100 threads about this same topic and you will the battery life increases after rooting and debloating. Im seeing anywhere from 21-27hrs battery life with around 4hrs screen on. Brightness 50% avg., wifi,data, and gps all on...no air plane mode!

I wonder if it might be helpful to list off the apps we all have disabled (or removed entirely for rooted users)? Might be an interesting comparison point. Here's mine:
AllShare Controller
AllShare Play
ChatON
Dropbox (interestingly, I have two of them listed and disabled- everyone else?)
Email (replace with K9)
Exchange services
Flipboard (I prefer the plain old Google Reader app, believe it or not!)
Game Hub
Gmail (I use the web version)
Google Play Books
Google Play Movies
Google Play Music

One other thing I just thought of: I'm using Go Launcher. Just in case TouchWiz is a power hog somehow

Was on wifi most of the day yesterday since I was at home, but I'm going on 2 hours of screen on (not much I know) and 30 hours and i'm still at 41% battery.

Here's my battery life:

Nothing running in the background - even using lowest brightness and power savings mode turned on.
Even when I was 100% stock, the battery was pretty terrible so I doubt there's an issue with the rom.

I'm pretty happy with mine. By the end of day yesterday it's 40% after 14 hours with just a little under 3 hours screen time. I'm on WiFi the first half of the day and on 4G the rest. Didn't seem to be much different if the 4G signal is decent. At work it seems drain a little faster without the screen on, I think due to the poor 4G signal here.

Yep I am loving this phone. It is getting double the battery life of my rezound which had the 2700 battery. I'm only losing 1% an hour on standby overnight. I don't have that feeling of - oh I want to play with my phone but I better not if I want to be able to use it in an emergency later.

I'm also coming from a Thunderbolt, but I had the OEM extended battery (2750mAh), so for me the Galaxy S III is a little more constraining. The Thunderbolt with extended battery would last through a day (~16 hours) with moderate-heavy use.
The Galaxy S III will also last ~16 hours, but the use has to be closer to light-moderate (~3 hours screen on). I've got power saving mode on, I'm not using WiFi at all, and I'm running it completely stock and unrooted (but with some bloat disabled).
Overall, I'd say the battery life is decent. I am, however, looking forward to an OEM extended battery.
