I need battery life!

Alright I have grown beyond angry at how crapy my battery life is...... I go into school with 100 percent battery and everything off except texting and calling (which I send like 5 texts all day) and I come out with less than 70 percent. I have low signal in the building though, and my phone is set to the lowest speed on power save and I hardly ever turn the screen on. I would like for you guys to share your battery life's here with screen shots if you have them and your whole setup. Thanks beforehand!

And If I use my phone it drains very quickly too.

try out different kernels and find one that works for you, also try out a black themed rom, will use much less screen on time

Why is this in themes and apps? This is a question.

Oops sorry can a mod move it?

Whats your ROM/Kernel combination? any OC ? And UV? I normally underclock to 1Ghz to save juice.

Signal strength makes all the difference in the world. Turn on airplane mode when in very low signal areas or at least disable network data. There isn't really any other way around low signal battery drain.

I have been using cm10 and the kernel it came with, and some custom profiles with set cpu that's about it...

What're your SetCPU settings?

Stick with Trinity, So far it works the best with me. Go with interactive/cfq for governor/scheduler or interactive/deadline.
I go to school with 70%, Listen to music on the way, then to work later, and after a solid 12 hrs. I come home with roughly around 40%. And yes, I text more than you do, 5 texts? Try 400 atleast a day, and I have 3G on the whole day..Most cases I just turn it off when I don't need it.

I also recommend lowering your minimum clock, since the device uses it quite often.

Nexus battery issue

Hi all. I have a gnex that has horrible battery life. I have tried using the stock battery and the OEM extended battery however I will only get about eight hours of use. I am running cm10 with lean kernel. I have overclocked, under clocked, and undervolted but has made no difference. I am including some screenshots so someone can try to help me or at least tell me I'm not alone lol.

How much screen time? Press screen in the battery option.
Sent from my SPH-D710 using xda app-developers app

1. Don't overclock
2. Don't use LTE
3. Keep your screen as dim as possible
4. CM isn't really known as a battery saver rom. Its more of a performance with stability type rom
5. Test out other kernels.
6. Check your apps to make sure you don't have one that's killing your battery
7. GPS should be off
8. Turning sync off will help too
Oh ya and questions go in the Q and A forum

If you're constantly in areas with low signal and data on, your battery will drain from trying to get a signal.

Well it seems like you're using the phone pretty hard on LTE with a 1.6ghz overclock... Sounds about right.

Yes, way overclocked. Is your phone actually using that frequency and is it stable. Lean exp. 5 can under clock on the low side to 180. Try that.
Actually your battery life seems quite normal.
Some folks are saying that Diet kernel gives great battery life. I haven't tried it yet. I'm wondering if it will slow my phone down too much. I'm loving the speed and stability of Lean kernel.

How is the battery life on TouchWiz Jellybean?

I've been using CM10, and very few times has the battery life been that good. I'm not talking about when I'm not using it, I've reduced that a bit, I'm talking about when using the device. Overnight, it only drains like 10% (still more than I'd like but I'm taking measures to make it less), but when I'm actually using the device, it drains really rapidly. Like, I'll lose 10% in 20 minutes just using Facebook, Instagram, Pulse, etc. I've had it on airplane mode overnight one time and it didn't lose a percent, so I don't think I have a bad battery. So I'm thinking it might be the OS, but I don't know, how is everyone else's battery on TouchWiz, and have you used CM10 before and had bad battery?

Heres my stats for today

I've got 2 hr 30 min of screen time at auto brightness
10 min talk time
Around an hourish of listening to music
I keep autosync, bluetooth, and gps off. Nfc and s beam on, im using ktoons kernel and running ktoonservative governor at 1.5 ghz.
This is what I've been usually getting day to day, i cant say how much facebook uses as i dont keep track, and i dont use instagram.
Ive been on task's aokp 4.1.1 and my battery life was about the same, maybe a little better. Overall, ever since i turned off gps and autosync ive been satisfied with my battery (as i dont need either on a daily basis) Hope this helps

Hmmm well like I said, while I could eliminate more background data, I think I'm fine with the data side of things. I also freeze my Google Maps app so it doesn't keep on turning on, but I do keep my GPS on. It just seems like a huge drain when I'm using apps, like I mean some CM10 nightlies seem to drain slower than others, but if you say your battery was about the same between OS's, then I guess it's just me imagining it. I always thought the GSIII would last longer though, on paper it lasts longer than an iPhone, but it sure as hell doesn't do it in real life lol. It's what I switched from and one of the reasons why I picked the GSIII over the iPhone 5, but ugh messing around with the battery is such a pain.

Haha yeah its a pain, but when you get it the way you want it's amazing. Also keep in mind that your signal strength, LTE connections, and how much you use wifi over data will also play a factor

[Q] Best rom for battery life?

Please my phone litterally died in 3 hours from full charge with 1hour screen on time
Running FINAL SOurcery and Faux 29u kernel underclocked at 1000 mhz with intelli demand

First things first, don't ask "best" type questions on xda. Everybody has different experiences.:good:
That being said, I am personally always running the latest AOSPA (Paranoid Android) and latest AK kernel. Great ROM, and absolutely perfect kernel. I usually get around 3 hours on screen time with that combo.
Of course, you have to remember that there are many many factors that impact battery life. For example, if you have data turned on (either 3g or 4g), gps on, or brightness high, your battery will suffer. Search the forums for various ways to improve battery life.

I always have the best results running stock for battery life.

Slim ROM + Fancy Kernal

Maybe you should look into purchasing a new battery.

^^^This. If you are having that crappy of battery life, its most likely the battery itself. No ROM or kernel is going to help you.

Mine too and i have baked +Franco.

Buy extended, cost me 5$ with case! XD
This is heavy use (3G only, no WiFi) also I'm with wind so having a crappy network signal kills it even more, yours will most likely look better.

What's normal battery Temp?

Hey Everyone was wondering what's the normal temperature for the battery? Here's a screenshot I took, I use the app called Devcheck great app by the way, great for getting all the Info you need about your phone.

Sent from my 2PS64 using Tapatalk

that temp is good, nothing to worry, everything up to 37/38 without gaming is quite normal. it depends whether you use mobile network and a lot of browsing or so or not.everything starting from 38 and above should be only reached with gaming

No need to worry about temperatures on the phone. It's not like a desktop with variable cooling systems. If battery or CPU is getting hot, it'll throttle to lower temps and will turn off in extreme conditions. Having Android phones since the D1, I've never seen anyone fry their phone from excessive temperature.
IMO, monitoring temperature on phones is as useless as ram cleaners. Let the software do it's job.

What's the normal Temperature of the Battery?
Room temperature obviously!
Everything else i abnormal. Like when you activate the screen and use your phone. This uses energy and causes the battery to become warmer.
Using a LOT of energy like Recording 4k or playing a Game which uses up to 8W will increase battery temperature.
1. the 8W Electrical energy get turned into 99.9% thermal energy, the SoC is between battery and Display, facing the battery IIRC.
2. The Battery being used causes itself to heat up.
So what is the Limit? Around 45°C The phone starts throttling CPU clocks and GPU clocks way earlier. Around 38°C is the first one and around 41-42° he next one. But depending on your surround temperature (Jep, Texas Sun at noon and 35°C Outside temperature do not help....) your phonebattery will not get hotter than 48°C
Is this safe? Jup easily, the battery iself should be specced about 50-60°C Maximum usage temperature. Didn't really take a look at the details in the battery in the disassembly video^^
But as Richii already mentioned, your phone does this all on its own. Don't have to care at all
It's note a Note 7 ^^
