OK so i installed almost every ROM on there and here is what i found.
TOP.
:good: CleanGB ---- Takes the crown, super fast battery charge in less then 45minutes the battery is full. Over a period of 8 hours in stand by(as i sleep) the battery did not drop at all.
:confused: CM9 ---- Took over 2.5 hours to charge the battery, in 8 hours it dropped 12% battery life.
First, here's the constants: I keep wifi/BT/GPS on 100% of the time. This was true when battery life was good, and now that battery life is bad. Disabling these will improve battery life, but will not fix my problem.
When the phone is sleeping overnight, I used to get 8-12% battery usage over about 8 hours.
I've seen lots of battery life forums, and most of them show great battery life (over 12 hours) with lots of screen time. I'm not even in an LTE area, but I get very good signal. My screen brightness is at about 30% and I have two e-mail accounts (Exchange push and Gmail sync).
I unlocked my phone, rooted it and installed Fish n Chips ROM.
My phone seems to have very poor battery life. I fully charged it to 100%, unplugged it, played a game for a very short while and I lost 10% battery withint 10-15 mins.
The battery just seems like a time bomb that doesn't last very long at all.
I've only had the phone 2 days now...
So I thought I would give this battery a shot. Its the KINPS brand from China. Originally with my stock battery I was getting 18-19 hours or so with my screen at 50% and with light to moderate/heavy use.
Is it normal for the battery to die MUCH faster after rooting. I rooted to oxygen yesterday and now my battery drains fast enough I can literally watch it go down. I listen to Pandora while Im at work and before the root I could listen to it for 6 hours and still usually have between 25-50% battery left. I just have the phone in my pocket with the screen off and rarely touch it.
So I've been this phone for about 3 weeks now. I love everything about it but the battery life sucks.. I've only used android since I bought my Note II. I caught up with how android works right now but I don't know what apps are draining my battery life. It used to run around 16 hours then it only lasted for 16 hours now. I charged it properly all the time.
Hi everyone,
I recently got the galaxy s4 with t-mobile, and I am loving it! Except, I am not quite sure if my battery life is normal. I have been reading a lot of different posts where people claim to get at least 11 to 12 hours of the phone, and up to 3-4 hours of actual screen time.
I have been testing out my battery, I uncharge usually in 9 am then I use it until the battery reaches 2%.
My battery charge used to last all day. A couple of months ago, it fell to about two hours tops. I replaced my old 3500mah battery with a brand new 3500mah battery. No changes. I use all the standard battery saving techniques such as screen timeout, screen brightness, leaving unneeded radios of, etc..etc..
Is it possible software upgrades or some rogue application is killing my battery.
