Longest time with Display On while on battery

To all the heavy users out there: I'm interested in hearing about the battery life of your phones under heavy use. I figured that the Display On time in Settings>AboutPhone>Battery>BatteryUse seemed like a good measure - the amount of time the phone display is on before battery runs out. Also, I usually have wifi/3G on almost all the time. To make a start here's mine (mostly browsing):
ROM: 2.29.405.2 WWE
Time: 4 - 4.5 hours
I'm quite happy with the results, though I'd like to hear other people's thoughts on this. Thanks.

i got about 4 and a half hours of screen time over the course of 2.5 days... tons of texting.

Great, which ROM are you using? My 4.5 hours was over the course of a day. I might consider flashing a custom ROM as soon as I can get my hands on a class 6 micro SD. The battery gives about 5 hours of on time for games, watching movies and other non data stuff, which is pretty decent I think.

Same here... 4,5 h is a good value. If I dim the screen for at-home-use (6% brightness via quicksettings) I might get 5 hours.. a lot of network/wifi usage or gaming of course decreases the lifetime...
BTW: I'm on LeeDroid 2.2f

i am using defrost on the 6.0i HAVS 1113mhz kernel BFS.
probably best rom around. really fast, and i can use 20% brightness and get 2 days worth no problem. hope this helps!

Yeah but this Thread asks for the actual running-/screen-on-times as stated in your battery statistics Anyways two days is quite good even with moderate usage...

if you hadnt already noticed i posted about my battery with screen on previously,

Depends critically on your settings/activity/screen brightness/screen picture...

Better battery life out of an extended battery?????

I have an extended battery (2600). I was wondering, what does everyone do to get the most out of their extended battery if you have one? I'm hoping to get tips and or tricks from my fellow EVO users. If you have nothing positive to say, please don't post.. Any help is appreciated.

Are you rooted?
I use the stock battery on my rooted Evo and it lasts all day.

It really does depend on weather your rooted or not cuz on my stock battery I can go about a day in a half maybe a couple hours less MAYBE but then I have a Seidio 3500 mAh that can go exactly 2 days 1 hour and 38 minutes with heavy heavy use and also on a charge of 93 percent
So again are you rooted?

http://forum.xda-developers.com/showthread.php?t=712990 check that thread, ever since i followed the steps my battery life is so much better. its been off the charger since midnight and i browsed fb for like 30 minutes, texted my wife n browsed the market for a bit and its only down to 89%. btw im using the stock battery.

Not really lol I think that's pretty good I'm guessing that you got that with moderate/heavy use?
You may wanna give another ROM a shot and see cuz battery life may very between them. As well as kernels.

Will give that one a go. I dled it a few days ago but i accidentally deactivated my EVO lol luckily i unrooted it and got it back to root just now so im going to give that one a go

Any stock kernel will not charge any extended battert correctly. I experimented with this for the last month.
I found an app called boot manager and now have 4 roms installed on my phone. At night I boot into a Froyo ROM with a SBC kernel and charge it, then in the am, boot into my Gingerbread ROM.

Yep. If I don't use my phone it will last all day and lose about 1.5% every two hours. I just recently switched to my current setup and am still not used to it. I'll unplug my phone at ~95% and head out the door. I'll pull it out of my pocket a number of hours later and see that it's only down to about 93% - 92%. Before I switched my setup I would've been down the low 80's if not lower. When I use it my battery depends on what I am doing with it and what I have my scaling set to. Using my phone for things like texting, facebook, email, and some web browsing on Skyfire, which is what I would consider heavy use, it goes down about 3.5% per hour. Yesterday I went to my little niece's dance class and I used my phone to record video of her entire 60 minute dance class. Battery went down about 30% percent from that but that's to be expected. I remained out of the house for another 8 hours after her class and my phone still had 50% battery left by the time I got home. Wireless tether eats up my battery. But Thats because I am usually tethering while texting and testing launchers and such on my phone.
I do all of this on a stock battery. So I can only imagine how much I'd be able to do with an extended battery.

I get 30+ hours on my extended battery 2600 from sprint. LOL on warm 2.2

[Q] Battery Question

hi. I was just wondering what you people are getting on your evo 4g. I have a rezound but my dad has this phone and absolutely loves it except for the fact that his battery life is awful. Couldnt last half a day it the world depended on it. so just wondering what your guys are getting on stock and custom roms

I'm using mikg ROM version 3.11 very stable and smooth can get around 12 hours on regular battery. But, I spent 6 dollars on eBay and got an extended battery ... I ran it from 100% to 1% 24 hrs 45 min moderate use

How did you get so much battery life? I tried it and it was dead with in 2-3 hours!

ROM for best battery life?

Hi, I'm currently running PA ROM on my GS3. For those of you who don't know, it's pretty much a CM10 ROM with Hybrid/Tablet Mode. I get around 12 hours out of a battery on a school day w/full brightness on. I'd say that's only about average battery life. I have multiple batteries so this doesn't worry me much. But I still want to get the most I can out of my battery. Any kernel or ROM suggestions to maximize battery performance?
(I prefer Stock UI and don't play many games at all. I pretty much have Temple Run 2 and COD Black Ops and I play COD maybe once a month)

What ROM has the best performance and greatest battery life depends on its user. You will probably not get the answer you are looking for by asking this question here. To find the ROM that will best suit your needs, you will need to go around looking at ROMs and flashing them. Make sure not to just determine a ROM's battery life by running it for a couple hours. It is a good idea to run a ROM for a couple days before you judge its performance. Most ROMs claim to have the best battery life, and they all do have the best battery life, it just depends on your usage! Good luck!

I had this old Hero about 3-4 years ago. That thing was a DOG. It ate through a fully charged battery. Even though i had as much bloat removed as possible. To make matters worse i was constantly going in and out of service with my job as i was constantly driving.
For the origional hero i had so many freaking Roms to try out it was crazy.....
To find the best way to test battery life. what i did was i spent a day, and i downloaded my top 3 roms, and turned my screen on. I timed it at 100% battery life and left my screen at 100%.
I then did the same test, but i ran a stress test on each rom.
And finally i ran each rom, and i kept a phone call connected to my work phone. (free nights and weekends)
Turned out on all three tests the same rom had the longest battery life.
Thats how i tested my old hero. If you are dedicated enough you could try the same.

OP, it's hard to say due to everyone using phone differently, do a search and you'll see many of these threads that are gone and buried because there is no definate answer. YMMV on any rom. So try a few see what works for you.. There's FAQ thread in my sig check it out.

Rule 1 states to search before posting. It will reveal a long list of closed threads and the reason in every one. They are all the best.

Battery Life

Am I the only person who notices that all these battery save kernels aren't working for them. I flashed CM and I have been getting amazing battery life (13+ hours) with moderate usage, but with leankernel for example, I only get 9 hours max and my phone heats up a lot.

Not working for "them"? Or for you? Of course they do not work for everyone. They also may work well for one ROM but poorly on another.

Well I was curious how kernels worked for others. Sorry.

No two phones work the same. I've had my S3 for about 2 weeks and have run Stock-rooted, and e few custom roms. I have 4 email accounts-pushed, 10 screen widgets, and always texting, web surfing, etc. I'm currently at 14 hours with 49% remaining. When I work in spreadsheets, and use a a reader, (usually 2 hours each) I still get 14-16 hours, no matter what rom/kernel I've been running

You just need to find the ROM and kernel combo that works well with your phone. I have tried ROMs/kernel combos that some get excellent battery life from but mine is horrible and vice versa. Keep testing as it is a trial and error type thing. Also your kernel settings can make huge differences. What works for one may not work well with your phone. Different settings on the same kernel may net you excellent results.

I have noticed battery life tends to vary wildly depending on ROMs and even people. I guess I don't use my phone all day long, but on a TouchWIZ 4.1 ROM, the app "Battery Left" (from Play Store, its free) reports that I can get up to 46 hours on a full charge, based on my typical usage patterns (and if I use Greenify). On the other hand, I have used an AOSP 4.2.2 ROM in the past (such as LiquidSmooth), and Battery Left will tell me, after a few days, that I will get about 25 hours on a full charge (again, with Greenify). I have to do more testing, but there is definitely some difference between ROMs and battery life...

I read this thread & thought battery life has as much to do with what's running in terms of synching, background data, services, connectivity etc.

I am using one of the unofficial CM11 ports that is supported nightly and have been getting terrible battery life. I hate to ask the question which is the "best", but what would be a good kernel to flash?
I do not do much heavy gaming either. In fact, I do not do any gaming. Just casual browsing.

Well before I suggest any kind of "good kernel to flash" I want to make note of something. If you're running a nightly of an unsupported version of CM11 then don't expect great battery life. This has little to do with what you're doing on the phone but the purpose of nightly's is to have users report bugs. Many of these bugs are the kind that can drain battery rather quickly. So the first thing I'd do is find a stable AOSP rom to run on before thinking about kernels.
That being said, a kernel universally accepted as "good" is KT747 by Koonsez

Thanks for the reply bud. I personally like supporting the nightly versions of ROMs but I wasn't thinking the reporting that I do is causing that much of a battery drain.
I may consider today to go to a stable AOSP ROM that isn't nightly.

I have been flashing ROMs now for the past 4 years. I have never really got into the nitty gritty of anything specific but probably best I do. One question I had in regards to all these ROMs is, do they not come with their own Kernel which I would have assumed is the best recommended for the given ROM. When i see battery life of 14+hrs with room to go, I must be doing something wrong.
Thank you for any info in advance.

poor battery life
i have CM 10.2 4.3.1 in my SIII and all i can get is 6 hours of battery life. how i can fix this?¿ also my phone gets hot vey quick sometimes without use it.
