As I posted in another thread:
I am lucky to even get 12 hours with minimal use. No calls, just some texting and maybe browsing my bank website. Screen is always the killer for me, even on 20% brightness. If I go lower the screen actually flickers.
I bought the red HTC Chichitech batteries and they didn't help me at all.
Tried overclocking module, didn't change much.
The only app that ever shows any significant battery use (over 5%) is Maps, when I use maps.

I am rooted, S-OFF, using the Sense Modaco ROM. Battery usage was no better with the Stock Bell Rom before rooting or S-OFF.
My main concern is the screen flickering at low brightness. it's as if it's unable to decide on a specific level of brightness and makes me question if it's actually saving any power.
I set my phone to Auto brightness and I am going to see if that is actually worse of if it's on par with 20%.
Ugh - just realized there is another thread pretty much all about this. I thought it was a different issue. Still, does anyone know if there is a better batch of phones or something? I have a FutureShop warranty so it'd be easy enough for me to replace if it will actually provide a solution
No-one has posted anything, to my knowledge, about a different batch of phones having better battery life. I would check out the other threads about battery life (including those on the G2 side too) and see if you can get yours to last better. But it could just be something faulty on your phone/battery.
Auto-brightness would make it even worse..because there is some type of bug or something that isn't making it function like it should. I was also getting terrible battery life until I followed some of these steps: http://www.goodandevo.net/2010/05/20-tips-to-improve-htc-evo-4g-battery-life.html
Biggest killers are any widgets that are constantly updating..or facebook/twitter apps that are constantly updating. As well..i recommend SetCPU to underclock your phone when your screen is turned off. This should also help with conserving battery life along with some of the steps provided in that link.

I am considering waiting a month or so and then having mine replaced. Unless I managed to figure something else out. My HTC Legend had better battery life.

The reason I want to try auto or higher brightness is to see if lowering it was actually saving me any battery life. I am curious if there's a driver or display issues that causes it to use the same amount regardless of the setting. So far I don't seem to be running out any faster @ auto than I was at 20%, but it hasn't been a long enough time to tell for sure.
Also I am unable to do the battery tip for the evo because once I turn off the phone and go to charge it again, it's instantly green. But I am going to try it anyway even though it's green.
Since writing the first post I used the OC module to get my phone to 1.2ghz. I have SetCPU set to run on boot with the onDemand setting. I have a profile that says to slow the CPU when the screen is off. From what I've read it doesn't make a ton of difference with this particular phone, but we'll see...

Yep, that's what I found too, when you try and charge it thinks it's already charged and goes green straight away again. But as you said, worth a try.
I just wanted to report back and say that I had my phone replaced. So far so good:
- No screen flicker issue at low brightness
- Battery has lasted nearly 20 hours with moderate-heavy use (played NFS Shift, setup basically everything on the phone after rooting, installed all my apps, backups, flashed some roms, 20+ texts, 3-4 short calls, showing people random apps.)
If it's not all in my head then this is definitely much better now!
Curious. It seems that everyone who reports the screen flickering problem has poor battery life.
Defective displays?
I feel my battery life is pretty bad as well. I've unplugged the phone this morning at 7 AM. Now it's 2 PM, and I'm at 37%. In between, the only things I've done are: send/receive a few emails and chat on gtalk. Brightness is at 40%, animations are turned off, wifi and gps location off. Using latest Cyanogenmod (6.1.1) and have no screen flicker issues
Edit: 17 minutes later, it's now at 27%
How long have you had the phone for?
Initially the first few days I got the phone, battery life was really bad, could drain in a few hours.
After a week or two of use, I now have reasonable battery life, the phone can last all day with light usage and still have lots of juice left. Actually I think if you make a few calls and a few txts, battery could last 2 days. If you play with it, one day for sure but you need to plug in over night.
(if you're talking to me) It's quite new, just picked it up on Friday actually. Also I've kept on researching, and it seems that poor coverage (like I have at work, from 7 til 3) tends to drain the battery even more, since the phone keeps switching between HSPA, 3G, etc.
I had my first one for about a month at least. This replacement was from Saturday.
Today I've had my phone unplugged since 8am, it's 5:30pm and I have 45% battery left, but the screen is the #2 user. Standby is #1 @ 40% of my battery usage, due to over 4 hours of time without a signal. The screen is only 24% and has been on for 48 minutes. Voice calls is #3 at 23% battery usage, with 23mins of calling.
My other phone would have died by now.
Also I spent an hour of streaming bluetooth audio to my car. Bluetooth doesn't even register on the battery usage. I've never seen it use more than 2% and it's always on. I am not sure why people say it uses a lot.
Just want to share my experience.
I too had poor battery life. Stock Bell ROM. Got to 3:00 pm and it used to die. Use this for work. Pushing data all day from Exchange server, bluetooth on all day because I'm in and out of the car, talk on average 30 minutes per day, texting, surfing, tethering, blah blah. Believe it or not, my old Omnia II would get me thru the day no problem.
I was also tempted to return it. But I decided to try a few things. Installed Set CPU and a task killer at the same time. Shut down as many tasks as possible on start up. Widgets and accounts, except Exchange-push, run and sync every hour. I get about 40% battery by dinner. I am happy now .
I'm quite happy with my Desire Z's battery life, It lasts for about 36 hours with moderate use. I have Juicedefender and Ultimatejuice installed, data or wifi are opened only when an app needs data connection, this increased my battery life by 10 hours or sth like that. Nice app.
I had terrible battery life until I went overseas. It is a stock Bell ROM, but I arrived in Spain Monday and am using a Spanish SIM card.
My battery life has increased from 14 hours with Bell's 3G signal to my current 27 hours and 35% remaining battery using GSM and WiFi always on. Funny thing is that no matter where I am it says the screen is by far my biggest power drain.
Where did you buy your Desire Z and how did you get it replaced? I'm with Bell and they would take mine to send out for "repair" but not sure if that will do anything. This will take 3-6 weeks apparently and I'm not sure if they it is worth it.
I'm running 10 hours with that I consider fair usage (few calls, text, map/gsp, and facebook.) My display is the highest battery usage at 60% and on for about 1:45h. I'm very disappointed.
Hey,
it's the same with my G2.
Max 24h.
I've standard ROM installed.
No WiFi.
Brightness to about 30%.
Juice Defender is installed and I'm surfing and just the regular stuff, but even if it's just in standby, it's taking a lot of power (display takes most)
Best!

I bought mine at FutureShop since I didn't think Bell would let me without buying at least a month of service (or being an existing customer). I also purchased FutureShop's extended warranty which is how I was able to get it swapped for a new one so quickly.
I use the extended battery for the evo. Lasts about 1.5 days with ass loads of use. Just have to trim the plastic edges a bit.

I have a couple of those red chichitech batteries but I wasn't able to notice any improvement with the problem phone.
My Desire Z also has a flickering screen at lowest brightness, and with moderate use it dies after about 12 hours max. Even on lowest brightness the screen ueses 59% battery. I rarely manage to make it through the day without having to charge the phone. Im on stock ROM with latest OTA (1.72) btw.
Gonna have it replaced next week just cause of the flickering screen. Has anyone tried the 1700mAH battery from seidio?
Hey guys. I've been noticing a while that a lot of people on the forums get 12+ hours even on heavy web browsing, calling, apps, and texting. I usually can't get through a day of usage (probably 12 hours?) with my phone, and I carry 2 extra batteries with me. I calibrated my battery using the battery calibration app here on XDA and my screen is set on auto. I'm on Syndicate v. 1.1.1 and I use the stock battery.
It will usually last me 3-4 hours of 'heavy' usage (calls, games, texts) and maybe 5-7 hours of 'moderate' usage (when I'm at school, some texting, barely any internet usage, and a few calls)
Are there things that can 'harm' a battery? Some people say it's bad to charge a phone and use it at the same time, but I call people while its plugged in multiple times every day (probably a couple hours worth a day). Does that deteriorate the battery?
I'll post a screenshot of my battery usage tomorrow if that helps.
(note- I am a calling freak. So far I'm about 3/5 in my billing period and I've used 10,580 minutes. )
The charging and using not so much but letting it repeatedly drop low and get hot kills it

the one thing i would do to extend your battery life would probably be to take the screen setting off of auto and manually set it to the lowest brightness you can tolerate.
are you using the twilight zone 1.1.1 kernel? try using the genocide 1.0 seems to give me better mileage imho
I have noticed this even with my extended battery. I am actually going back to 1.1.0 with Vision kernel to test.
Phone calls kill this batter no matter what. Our specs for talk time is 4-6 hours I don't remember
So 3-4 hours on heavy usage is normal if I'm doing excessive calling?
Some days I have a 5 hour battery, some days I have a 20 hour battery - all depends on how I use the phone.
On the short days I use it a lot, I'm throwing attachments around in Gmail, files around in Dropbox, using 4G, and using my phone outdoors - read brightness up.
On the long days I'm using Juice Defender and Screen Filter - read brightness down - I'm mainly texting and powering the screen off asap, and getting in the occasional fb/tw check, and I'm hanging out in areas with stronger Sprint service.
My advice for elongating your battery - use Juice Defender and customise which the data controls by app. Use Screen Filter at about 60% and manual display brightness. Slide your finger left and right along the window shade to keep the brightness down. With the SAMOLED the more dark colours on the screen the longer the battery will last, so always pick dark themes on apps. If you're going to be in a low service area for a while toggle data off if it's an option.
Lastly, I picked a Zagg Sparq for this phone. I charge the Sparq in once or twice a week and then I plug my phone into it on the go on those days when I have trouble. Use the General port instead of the Optimized one. I played the multiple battery game with my G1..I prefer carrying around a juice box.
Have tried any of the "tricks" posted by Randomking?

This is from my first full charge cycle. Completely stock. Amazing! This is 3.5 hours screen on and 2 hours voice calls. It's not letting me upload those screen shots for some reason.

Yeah mine has been pretty solid as well. Yesterday after 17hrs I was still at 35% which is better than most Android phones I've had.
I really think that galaxy nexus standby is amazing but the screen is the only thing that really drains the battery. So if you don't use it heavily, you should be fine. I use my nexus moderately and I still get through a day with about 40% left.

Pretty good... i find voice calls and cell signal to be main battery drain cause on Sprint's turtle 3G network.
With 2100mah extended battery, 15% juice left unplugged at 8:30am, replugging in at 10pm, 2.5hr screen, 1hr gps, 30min voice
2nd full charge cycle
Here are the results from my 2nd full charge cycle:
40+ hours off charger; 4.5 hours screen-on time. Remarkably good.
How are you getting such good battery life? i can't seem to even last a whole work day, requiring me to charge before I leave the office.
I just got my replacement, so hopefully it will be better this time around.

I use 30-40% brightness. Black wallpaper. Other than that, nothing special. I only have 1 gmail account syncing, unlike some of the people on here that have 3 or 4 email accounts syncing. I also only have like 2-3 widgets running (beautiful widgets smaller home, audiomanager pro, astrid, and maybe one or two others). And most of the screen on time is doing relatively simple tasks like web browsing, reading xda, google talk, etc. Nothing too terribly intensive like video.
Based on my experience though it seems like pretty much anybody except the heaviest of users should be able to get at least a full day's use out of it, and lighter users should easily be able to get 2.
Is yours GSM? I hear the Vzw/Sprint ones get far worse battery life.

I agree. I ended a day with ~70% battery left, and most of my usage was the screen (~30 minutes or something). I haven't had any issues with my battery dying on me yet. If I left the screen off all day, I could probably use 10-15%.

I'm guessing it isn't using LTE. If I only connect by wifi and turn off data syncing then I can get more than a day too (with moderate use).
LTE really drains the battery.

Correct it is gsm, not lte.
That's impressive! Stock rom allows you to get at least 20 hours of WiFi/3G with 3-4 hrs of screen. Auto brightness. Here in Europe we don't have LTE, so our batteries could last a little bit more.
avarage battery use is over 13 hours (cm9+franco kernel).
10 hours and 53 min it dropped to 94% worth mentioning I didn't even touch the phone, can't seem to post a screen shot of it
Right now I am at 45% and I used it quiet heavily today
I didn't charge the phone even if it sems like it

Some of the best I've seen so far from my phone (about two weeks old) is posted here. Almost 36 hours of uptime! Wifi on the whole time, had a signal for most of it too, but guarantee there were some times that I didn't (because I was trying to use the phone then). This includes time spent playing some games as well. I've fired up Osmos HD, Everlands, Swords and Soldiers, and Draw Something at some point during that charge for at least a few iterations of play on each game. Decent amount of browsing, including hits from Google Shopper for some price comparisons. I'm syncing one Google account and one Exchange account, with black wallpaper, auto brightness (not tuned) and the calendar, news and weather, settings, and prepaid usage widgets. Stock ICS and unrooted.
i have ext battery and can run (what seems like) forever
I am just wondering if it was because when I purchased it I charged it from it being completely dead to full.
Then using it for a few hours. recharged it from 59 percent back again to full and left it to charge even though it said it was full.
Btw I havent rooted just the stock rom. And I can get through two days with moderate use and still have 10 percent. I have no issue with build or software.
I am pondering whether to upgrade to 1.29 when it is released for my network because I have no issues at all.
I had a small glitch when my phone woke up multiple times from scratch but it was software that caused it since uninstalling it. it hasnt occured since
base band 1.1204.103.14

To get 5hrs is extremely impressive. I once did a test by have the phone sitting idle in airplane mode with brightness set to 50%, and the phone lasted 7 hrs 45 mins before the battery died. So only 1/3 drop in screen on-time with Tegra and data usage included is great result.

There is like 1000 different things that affect batt life.
The two biggest battery drainers are the screen and the mobile data.
Especially if u are in a location with low signal (either it is 3g or 2g).
I have my mobile data / wifi ON at all times and I average about 20 hours with about 2 hours screen on and TONS of accounts syncing (friendcaster push, twitter every 2 hours, gmail push, google contacts, calendar push, facebook calendar, whatsapp, viber, weather, ebuddy u name it ) so I guess it is alright.
Now with mobile data off I believe I could easily get the battery life the OP has reported but that's not really the point is it?
Wow you guys have amazing battery life. Makes me think my phones faulty haha

I haven't seen a battery life thread for the AT&T S3, so I'll start one.
Mine is around 13 hours with moderate use. I listen to podcasts for an hour in the morning (commute to work), read Pulse News and Facebook for about an hour at lunch, and listen to another hour of podcasts for the commute back home. By the time I get home, I'm around 13% life. I usually get the battery warning while listening to my podcast. In comparison, my GNex GSM gets 17 hours with the same use pattern. When I get home, I'm usually around 37%. Besides Samsung's and AT&T's bloatware, same apps, no widgets.
All told, I am very disappointed with battery life. I don't believe in underclocking my CPU in or disabling haptic feedback. I use the "Power Saver" mode, but only use the reduced screen power consumption feature (reduces framerates and brightness). WFI is always off (I don't have WIFI at work). I also disabled all of the Motion features. I disabled S-Voice (it monitors for the Hi Galaxy, and disabling also allows for a very responsive Home button).
I calculated my idle battery drain (unplugged when fully charged and not touch it) at around 4.4% per hour. That only gives 22.7 hours of standby! My Galaxy Nexus GSM can go at least 2 days (sometimes I forget to charge it at night on the weekends - also not used the phone).
Is it AT&T's LTE? Is it the Gsiff_daemon process? Is it TouchWiz? Or is it just my phone?
What's your battery life like?
You pretty much hit it right on the head. I had the extended battery from Samsung on my Gnex and could easily get 20 hours with moderate usage.
This phone despite using CM10 or AOKP with the JB kernel I never see battery life that good. I'm in the 14-15 hour range with about 3 hours of screen on time. That's with wifi off, and we don't have LTE yet. All in all, it isn't very good.

Stock? What features do you have turned off? Do you use WIFI exclusively? Do you turn off your data network (LTE/HSPA)? Did you turn off Sync?
I don't use WIFI, and I leave my data on (as it should be - just like I had it on my GNex). I also leave sync on. I understand that using these decrease battery life, but come on... not like this. The GNex faired very well, and it had a smaller battery. Besides LTE and an S4 (and the S4 should be more power efficient), there isn't much different between the GNex and the S3.
If I turn on the screen for 8 hours, there won't be enough for sleep time! It'll just die... if it even makes it to 8 hours...
20+ hrs with multiple accounts syncing at 1 to 2hr intervals, screen on time of average 4hrs. Heavy use. Wifi on all the time.
stock, rooted, debloated, super-aggressive power management I was getting maybe 12 hours with 2 hours screen time.
I saw you didn't believe in underclocking, but I started using Cpu Editor http://forum.xda-developers.com/showthread.php?t=1798765 and am loving it, can do 16 hours and 4 hours of screen time with no problems, will do the trick for me.

You have a faulty radio.
I consistently get 40+ hours off charger with 4-5 hours screen on time with a couple hours of browsing, 3-4 hours of music, texts, an hour of calls or so, playing casual games for another hour.
Stock. No hacks. No root. Disabled all unnecessary carrier and samsung apps and disabled GPS unless i need it. Auto brightness, 2 hours sync for weathereye, flipboard and gmail syncing all the time. I do mostly use Wifi at home because my signal at home is bad and that quickly drains my battery. At work my phone idles for eight hours at a 2-3 % loss with 3G on (i use my old SIM, i do not have an LTE plan, I am on Rogers Wireless).

I just factory reset (wiped data and cache) the phone and installed the apps I need (maybe something was badly configured or something) - did that yesterday night. Charged it up for this morning, and now I got 18 hours and still have 17% left. Screen on time says 1:38 hours.
This is on the same stock rooted and deodexed ROM. No hotboots either, so gsiff_daemon didn't rear it's ugly head.
Also no CPU Sleeper or any of these underclocking apps. I'm happy now, but wondering wtf was causing the problem... and will it happen again (after all, this is only day one).
I'm getting about 13 hours with 5 and a half hours of screen time. Underclocked to 1.2ghz and I have my own screen off profile. Great battery in my opinion

Phone finally died. Just over 19 hours. Heavy use towards the end because I was downloading and installing the rest of my apps from Google Play & Amazon App Store. Was also setting the apps up ( accounts, settings, and notifications...). Final screen on time was about 2 hours.
It's only been two days since I've had the phone, I've gotten about 14 hrs with roughly 3.5 hrs screen on time. I hate when I see people with 2 days off the charger and ridiculous screen on time. If you put the phone in airplane mode and ran just the screen you probably wouldn't last 10 hrs unless it was on low brightness. I had the Razor Maxx and I could get around 30 hrs usage with 4-5 hrs talk and 6 hrs screen on and that's the best battery life I've ever gotten on any phone with real usage.
I would like to get better stand by and more screen time out of this phone without getting an extended battery.

Nope. Stock battery. May be some of you have faulty batteries/radios/firmwares or run too much stuff at the same time.

No airplane mode. Cellular connection is always on even during the night. Only difference is at home i have wifi on instead of data.
Flipboard, weathereye and an appsales app syncing every 4 hours. Auto sync for google account and facebook. Automatic brightness. Almost all samsung and Rogers apps disabled (except for myaccount and a couple samsung apps) and motion disabled since i have no use for the gestures apart from being a novelty the first week.
No root. No hacks. I am actually amazed. This is the first android phone that has battery life on par with my iPhone 4 and the unparalleled smoothness. My HTC One X lagged, this never does even with a few apps installed now including games. I look at my iPhone and think "why do i still keep it? It is no longer relevant".
Ive got my UV tweaked just right on my ktoonez kernel and keeping my screen level as low as can be and I'm now practically making it to TWO days battery life! Plug in every second afternoon or evening after moderate use. Occasionally it doesn't last as long. Quite happy now. Oh and that's with this baby cranked to 1.809Ghz! But obviously tweaked to use that under strain otherwise using lower clocks and deep sleeping with 384mhz.
Got a 4200mah extended battery on way and can't wait to see how much I can squeeze out of it too.

My GS3 i747m lasts around 50-55 hours per charge cycle..
It is running stock Rogers GS3 ICS, not rooted, all stock. Battery is stock as well.
Not using LTE, using HSPA+ ("4G") with data turned ON with Sync turned OFF
(**NOTE: sometimes, the battery is drained due to poor reception, and the phone will use more power for the cellular signal.. In my case, my 3G connection in my area seems alright for the most part, about 1 bar less from full)
Power saving is turned ON. WiFi powersave is turned ON.
Moderated WiFi usage in 2.4ghz 802.11g-mode only.
Every night when I go to sleep, my flight mode is turned ON. (I sleep around 9-10 hours everyday, so the phone stays on flight mode for 9-10 hours a day)
In the morning, I turn the flight mode OFF.
Bluetooth, GPS both are turned OFF
Screen brightness turned 1/4 brightness
LED notification turned OFF
Also, I have a task killer killing ALL BACKGROUND SERVICES every half hour.
Without killing all the background apps, my RAM usage is around 600-700 MB out of 1.6 GB of RAM
Killing all the background apps brings the RAM usage to around 360 MB of 1.6 GB
Without killing background apps, my battery life is shortened even when the phone is on standby.
Do this, and your battery life is pretty good..
