extend batterylife ?

hi..are there any hints on how to keep that poor battery alive as long as possible ? mine only keeps up for a day, even though i dont mess around that much. ive already set all energy saving options to the maximum, but not much of a change yet. is there maybe a energy saving rom or something ? or do u have general hints how i should treat my battery...maybe charge it while the device is off or somethin ?

How old are you???

You are kidding right?? Are you the same guy that asked for a software that charged the battery while running in the background??? Lol

using light sensor (auto backlight) lead to using more battery (rather than maximum backlight) (10of10)
i tested it .

Suddenly bad battery life = battery gone bad?

Basically, a few weeks ago I flashed assonance 5.0 and my standby battery life was terrible. The battery would die by the time I got out of school which is around 7-8 hours of standby time.
So hoping to solve this problem. I flashed the captivate version of doc's rom and I have the exact same battery life. I have recalibrated the battery many times as well.
Sooo, do you think my battery has gone bad?
And if so, any good places where I could get a spare?

Many have posted eBay has some good deals.
I still suspect that many of these phones were shipped with crap batteries hence the differences with people using the same roms having much different battery life.

Well the thing is that my battery life wasn't terrible before. Or not this bad at least :x

Have you at least tried reflashing to stock to see if the problem is with the roms or with your battery?

Not for an extended period... but the thing is I read through some of the rom threads. And if it was the rom people would be complaining about battery life, but no one is :/
In fact, it is quite the opposite...

kernel related or bad battery!!!!

Well i am using Glitterball's latest kernel before Firebird. Or the stock kernel that came with the Doc's Captivate Rom 7.0
Either way, there has been a huge drop in battery life and I do not think it is kernel related, because on the Assonance 5.0 rom, i was running Setiron's 1.4.7 kernel with the exact same problems with battery life :'(

This is highly dependent on how you have your settings on your phone.
1) Wi-Fi constantly looking for an active network connection? At least have it go to sleep when the phone goes on standby. I only turn mine on at home or otherwise need and have access to it. Otherwise its off.
2) GPS running all the time? Personally, I rarely ever need to use it, but it runs great when I do.
3) Display at recommended brightness or higher? Recommended or less is best as far as saving battery power. I like mine all the way down. Don't need/want it any brighter.
I even tend to use only darker wallpapers as bright and lighter colors pull more power on AMOLED screens. This makes a little bit of difference. How much I don't know, but I do know that it does. Sometimes the above settings like to change on you. It's a good idea to check 'em once in a while.
While it's usually always around 60% full when I go to bed, I still charge my cell every night.
I have found that the speedmod kernel is real good for conserving battery power. Not downing other kernels as they're all real good. Speedmod handles battery consumption better in my experience.
Have you installed any new software that might be accessing the network checking for updates/feeds, etc?

1)I always had my Wifi sleep policy on never. So its not what is affecting the battery life
2) Never have GPS on unless i need it. Heck, when i need it, it never works.
3) nothing that i didnt have before.
Basically, I haven't changed anything to cause the decrease in battery life.

Your two biggest drains on battery are WiFi (especially when consistently seeking - any new access points where you leave it on standby all day?) and your display. Could it be your battery? Sure. Go exchange it at AT&T. They shouldn't have a problem exchanging it for you

Well the thing is. I have never had this battery life with my Wifi settings left untouched. So yeah, i will probably get a new battery from AT&T tomorrow and report back if it was the battery or not :]

give this thread a quick read, its more based around 2.2.1 roms but you could find some good information

[Q] Newbie question about battery usage

Hi guys,
It is a question about battery used of cell standby and phone idle.
It seems they used pretty much percent of battery.
Is there any tweaks or settings to reduces the usage of these functions ?
PS- i am using Zeus v3 by Huexxx

Root your phone. Uninstall all the useless programs. And use Autorun manager. Other than that i don't think there is anything for "idle" and "standby". Those are the times your are not doing anything at all.

Another good trick is to turn off 3g when not in use as it chew a bit of battery life. If im being vigilantand not using my phone to heavily I can get an extra day out of usage by doing this

I personally will try out a 1900 mAh battery from China.
The battery life is pretty annoying.

If that last longer share with us. But i don't know about China stuff. There are these good stuff and there are these.. You know. Be careful when charging though, i saw a chinese stuff got blown up.

Check the link in the previous post but what I say is 1 day batt is fine compared to laptops or netbooks.

Battery drain

So I am currently on 5.1.1 rooted with Franco kernel. Before updating to 5.1.1 I had 3h and 44 mins SOT and still 16% battery left. I read that flashing Franco kernel will help my battery but I am currently on 55% battery with 1h and 40 min of SOT. I have greenifyed all the battery draining apps like Facebook etc and I don't have any widgets expect Google keep. I have attached couple of pictures if someone could please look through them? I did several factory resets and still the same battery life. I am just browsing and watching YouTube videos. Now I only get 3hrs and 15 minutes before my phones dies
It's driving me nuts, I read that Franco kernel will help my battery life but it's still the same. I have around 40-50% screen brightness.

Have you done any modifications to your CPU or anything like that?
Profiles/governors etc.

No nothing. Just flashed Franco kernel free app so I can't adjust any governor

regardless what you were told, flashing kernels does not help battery. its your use and the quality of your signal that will determine your battery life. kernels might help you in saving battery, because they all change how the CPU works, but its up to you to save battery, not the kernel.

Yeah I read that you'll get better battery life with Franco but I don't know. Is there something unusual from my screenshots? Is there anything I can do? I mean I am using my phone as normal as possible and I even turned of lte and running only on 3g. I just want to know what the culprit is. I even removed viber but it's still the same issue

what percent brightness do you use? I keep mine at about 0-10% mostly, and average around 5.5h sot. if I raise my brightness to about 30-35%, I lose about an hour of sot. but really, its all about what you are doing with your phone. if you are a heavy gamer, you'll see much less sot because CPU intensive games will go through the battery quickly.

Your best shot is getting the full version of FK app and then controlling your CPU.

actually, 0-10% isn't that dark. if you set adaptive brighrnes, 0-10% will actually be darker. 0-10% is fine for me, unless out in the sun. but with 50% brightness, I'd say 3.5h sot is actually fine.

Really? I have 50% on all of my phones. I'll try 10% and see. Is activating the adaptive brightness good for battery life?
Just want to know really if my apps and system is behaving correctly. If it's the brightness that is the issue then it's a relief. But I read that everyone got better battery life with 5.1.1 except me :-/ I mean I have Bluetooth off, gps off, hepatic feedback and sounds etc all are off. Even Google now is off

no, adaptive brightness is bad for battery life.
and for the majority, battery life is exactly the same on 5.1.1, like before. as many people that claim better battery life, just as many, if not more, will say its the same, or worse.

Of course that it would help. I got 7h SOT with my old S3 running a custom kernel. But after all.. Try it out yourself

Yeah that might be hit or miss with every update. But I still feel like one should get better SOT even with like 40-50% screen brightness, I have all the big battery hogs turned off like GPS etc

I am running the kernel but it's not optimized and I don't know what the default settings for Franco kernel is. I thought I try the free version to see if I get better battery life but I feel like it's almost the same as stock kernel

first off, paying for the full app will give you what, more control of your CPU? do you know how to control tour CPU? if so, there are many FREE CPU control apps. learn what you are doing first, then buy the app. secondly, no one that uses 50% brightness gets great battery life. the screen uses the most battery, raising brightness to 50% will just let it use MORE battery.

I know that you can control your CPU, I've don't it before on my older android phones. I'll try the suggestions regarding the brightness

Ok so I downloaded Franco kernel the full version I will try it, what settings should I try for best battery life?

that, my friend, you have to find. considering that we all use our devices differently, you have to find what works for your device best. there isn't a magical setting for battery.

OK thanks mate, ill lurk around the forum and see what can be done :good:

What's the best setup for optimal battery life?

I only really use my z1 for Spotify, LINE, reddit and Facebook. Currently the battery life isn't so great as it needs charged during the day..
What's the best rom/firmware etc to flash which will give me the best battery performance?
I've not been on xda for quite some time so I'm a bit out of the loop,I did some looking but couldn't find a definitive answer.
Cheers!

I'm on stock but rooted lollipop, with Stamina mode and Greenify helping each other out. Also I underclock down to 1GHz but I'm not quite sure if it helps.
On all my past devices running the stock firmware almost always makes the most out of your battery.

I am on stock firmware already, I got greenify an the donate version but after testing it yesterday it didn't seem to make much difference.
Perhaps this battery is just dying cheers for the advice though

Sorry for late reply, didn't get notified.

I think that's normal pretty normal battery if you use Spotify+LINE+reddit+Facebook with 2 out of 4 signal o__o
Well the thing is that when you play music on spotify, your phone cannot sleep.
You should try to get a better signal/reception of wi-fi and cellular. I have read that these without good signal could cause battery drain, as you see, cell standby at 9%. Sorry I don't know how to improve those but :/ yeah..
Maybe try "Stamina Mode" if you didn't activate it (It should have a + logo next to the battery when activated)?
Lower your brightness if you can, that's the biggest drain!
At last, for a rom suggestion,I don't have because I'm stuck on stock roms ._. , maybe try some custom roms when you have free time

Yeah it's not too bad I guess, I just use it more than I realise. Already running mxrom, I've found stamina mode doesn't make much difference.
Thanks for the tips!
