Battery Life test Results

I was pretty pleased with my results here, so I thought I'd share. This is done with both OC and UV and making use of the the 3500mah batt and with moderate/normal use.

I can get that on stock battery, you must play some games and leave your phone on full brightness at all times or something.

No, I play one game in particular, and I spend more time on the web on my phone than most people do on their computer. I could get that on a stock battery too, if I never actually used my phone Before the the changes I made, I was getting significantly less life. Especially with OC.

It looks like the moment you turn your screen on your battery life plummets.

Thats from Oc'ing to 1560 lol

It's more useful to post test results on a standard battery and standard voltages and clock speeds so others can compare. I've gotten 3 days on stock CM7 nightly before, it really depends on how much one uses their phone. The biggest clue to how a ROM or kernel affects battery is to look at the idle drain (maybe with data off too). It should be flat or with < 0.5%/hr drain.

Where'd you get the 3500 Mah battery you are using? I've been trying to find a decent maker for one.

Best battery life opinion

I know its standard to protocol to answer these type of questions with read and flash em and decide which is best. Problem is that its not for me, its for my girlfriend who is not very tech savey to say the least. She is complaining of battery life so I was wondering if there was a rom that was/is perfectly stable with good battery life. Performance isn't an issue as neither is eye candy or tweaks. She is pretty much out of the box type of person. She left ios because of the bigger screen and other functions ios doesnt have, but for the most part she is typical iphone user. I just want her to get better battery life.

HTC one x you press the capacitive button to the right of home then you swipe up on the app to quit it.Now If you want to permanately remove bloatware/other processes, you have to root the phone ...although juice defender ult is a great app..the one x battery is great for me..even when I was on stock..maybe turn off fastboot( in power settings) turn off all the sound, Screen brightness low, touch settings(vibrate when keys touched..etc).check push notifications manually.. believe me android is more productive in battery life then IOS. Hope I helped. A thanks would be appreciated

Try paranoid android 2.54 with stock kernel, gives me the most battery on screen usage with 4-5 hours and 14 hours standby.
I also have screen brightness set to auto and auto sync for gmail, whatsapp, and twitter. I switched from cleanrom 5 and I'm loving this one.
I have tried most ROMs including cm10, kingkang ROM, etc

Would you say aosp Roms are more battery. Efficient than sense?

Also for each Rom do we have to also flash the kernal seperately using the all in one tool kit by hasoon?

CleanROM has the best battery life for me. It's also extremely stable.

You need a rooted sense ROM. Debloated. Root it so you can flash a kernel that has some has undervolt applied like elemental 2.0.

Yeah sense ROMs for me were okay for battery but the PA 2.54 has actually proven to be better for me at least. Try them all and see what works best for reliability and such, I spent 3-4 weeks discovering what I liked most

Cleanrom with 2.40 or 2.41 radio/ril and beastmode kernel.
CM, AOSP, and other non sense roms seem to be having battery issues. Random steep drops in battery level.

I think the kernel is what allows the better battery life, not too sure though.

From what I've seen on the dev forums, it seems like the majority of people have not had a lot of luck with battery life while using CM10 (just my perception, though. I'm on CleanRom). I definitely think a good kernel will go a long way (especially if you underclock things), but the ROM will play a part if a lot of software has to be running all the time to support ROM features.

Kernal has more to do with battery life hence the reason people are not getting amazing battery life on aosp roms for our phone right now. Kernal is still a WIP. I am hoping we see jelly bean sense roms soon, might give the best of both worlds.

Hey guys, I've recently bought a AT&T HTC One X. This is my first smartphone, and it is fully stocked, locked bootloader and no root, android 4.0.4 and software version 2.20.502.7, really like the phone. However, I am not really impressed with the battery life. I would usually charge it over night for around 8 hours, take it off in the morning at around 08:00, take it to school, casually check facebook/gmail, maybe watch one or two videos and by the time I get home at around 15:30, the battery would be at around 15%. I was wondering whether this is normal and if there is any point of my rooting the device and flashing any custom roms?
I have disabled all the AT&T bloatware, decreased my screen brightness to around 25%, no live wallpapers, disabled auto syncing, wifi and mobile data mobile switched on only when I use it, only have a weather/clock widget and a couple of games. So I have been researching about rooting and customer roms for about a month now, and found out that some members have amazing battery life times with Cleanroms and custom kernels, so I was wondering whether the latest 5.1 Cleanrom with a Beastmode kernel 4.4 would cause any damage to my phone and whether any of you guys are using it?
Thanks for your time!

Big speed increase...Read here

If you haven't already heard about it.. 'SEEDER', new amazing App. Made my phone a good 3x faster. If you are rooted it can be found in the app store. I flashed the .ZIP. You can find it online here. http://www.droid-life.com/2013/01/0...n-nexus-7-and-others-with-seeder-application/
P.S this work with any Android device. Have fun
Yes I know this should be in apps and themes but everyone deserves to see this, especially us Tbolt guys.

This has been proven to be a placebo affect. I have tested it for almost 3 days now and it doesn't really help at all. Also someone mentioned in that forum it doesn't work properly with snapdragon processors because the rndg is different than others. If it does help at all I think it would help more for the lag that comes from not rebooting for a long period of time.

I have been using it with unsense and it hasn't really improved anything. No difference in performance without it either. Like I said it's a placebo caused by the fact that the tweak actually wakes your processor repeatedly which is why your phone seems to react better. You can use it if you like but it is really just a battery drainer. You can get the same performance increase by setting your governor on performance.

What rom are you running?
Sent from my ThunderBolt using xda premium

I ran it on nu sense and it drained my battery and noticed no improvement in speed. You see an increase because you want to see an increase. Its like throttle body spacers people puts on their cars. Suppose to improve performance and increase fuel mileage. They do no such thing but make a nice paper weight. People who had them swear they could feel an increase. One guy put his truck on a dyno and tested with it on and with it off. His results was with it on he lost a few hp. This is why butt dynos are so inaccurate because we make our selves believe we can see and feel a difference. When in fact there isn't.

Like I mentioned in my earlier post. It cause a wake lock on the processor making it wake repeatedly which is the likely reason that anyone notices anything. It in no way shape or form affects entropy which was the original intent of the app. Google has also stated that the very issue this is supposed to fix was actually fixed with the release of ICS. Try it on a gb rom and see if it actually works. Also, after you run it for a few days disable it and see if there is a decrease in performance. I've ran it for about three days and there is no difference without it running.

Google devs have stated that there was an issue with entropy in gb roms so there is no doubt that it probably helps it.

I have installed Seeder on my Gingerbread (SkyRaider Zeus) Thunderbolt and 4.2.1 Galaxy Tab 10.1.
In neither case has it improved speed, launching or operations.

Don't Ask this kind of question, it's not productive, and it depending a lot of your use.
Test yourself and you will see.
http://forum.xda-developers.com/showthread.php?t=2477889

there is no best kernel for battery life. with any kernel available, you can have great battery life or absolutely terrible battery life. the kernel isnt the key to battery life. battery life depends on your personal usage, your personal setup, your personal apps used, and very much on the quality of the phone/data connection around you. everything elae is minor.

Yep agreed. You can "tune" any kernel to favour performance or battery. Its just different devs have different ideas about what the optimal balance is so defaults vary.
Its all about reading, learning and tuning.
Sent from my Nexus 5 using Tapatalk

best way to know is to try every kernel out there

We do not allow best ROM/kernel threads on XDA. Everyone has different uses meaning battery life varies from person to person. Best thing to do is head over to the development section, try some out and see which best suits your needs.

[POLL] - Do you use Dalvik or ART?

Just like the Title implies. I am trying to get a good idea on what runtime users perfer.
I like ART but its a batter killer and some apps are not compatible. Luckily I am not concerned about incompatible apps because I have not come across one that I use.
I would like to know what you use...
Do you prefer Art or Dalvik and why?
Everyone is encouraged to join in... Even if from another forum :highfive:

ON the M8, which is already stupid fast... It really brought it up a notch.
The best way to describe it is that apps load almost instantly. Its like the device is clocked to 3GHZ or something... It really is that notable.

Dalvik. As others have said I've really seen no difference in performance or smoothness I haven't tested long enough to test battery. Maybe furture android versions might have better use for ART they still don't consider it fully functional I thought almost like beta phase maybe.
Sent from my HTC6525LVW using XDA Premium 4 mobile app

Dalvik, for broader compatibility, and to be able to use Xposed Framework. Battery life is so amazing the purported gains of ART don't make it worth the loss of being able to make modifications.
My name's Harold and I'm a flashaholic....

Dalvik. Art breaks too many things, and on the 4 devices I've tried it on the speed benefits are negligible.

Dalvik, one incompatible app is one too many. Stability is always my main priority!

I prefer ART, but I need xposed so I'm on Dalvik. I personally see better battery on ART.

Dalvik

I'm using ART, basically because it's newer. Newer must be better!
Right?!
Anyway, I have no idea what the difference is between the two, but I actually thought ART was supposed to *improve* battery life. At least I thought I read that was one of the missions of the project.
---------- Post added at 09:34 AM ---------- Previous post was at 09:22 AM ----------
Just to follow up, everything I can find on the net at the moment indicates ART should/does improve battery life. It's less of a strain on the CPU so that would make sense.
Scott you know a hell of a lot more about these devices than I ever will (and probably more than most of these internet sources) so if you say it's the opposite I'd be inclined to believe you.

I just switched to ART... Been about a week and I notice that there is no more lag when opening my keyboard and no lag when swyping... Only app I see crash so far is quadrant but no biggie....
Does ART effect the kernel possibilities? I want to try faux again but don't know if it will cause a reload of everything if it breaks

I'm not using ART because frankly on this phone it's not necessary. It's just as fast without ART as it is with it, unlike my DNA. and I use Xposed framework modules so it's a no brainer for me

I'm far from knowing everything. I just read one article and it show battery drain statitistcs of art and dalvik on identical devices set up identically. Art drain was higher.
I dont know this test to be as all conclusive so take it with a grain of salt.
