Screen on time?

Yeah..screen ontime would help. I usually last like 14 hours with 5 hours screen on time. I don't hold back since I have a spare on the external charger lol.

Its ok if you're a hard core user like having your face stuck on the screen all day long

You should give undervolting a shot if your kernel supports it. That helps with reducing power consumption while in use, while juice defender helps with reducing power consumption while not in use.

Heres an update no charging

That's not very good, even given the fact that you're on 4g the whole day.
You need something like JD. The 4g looks like it's killing you.

I dont know what's going on but I never had a battery drain like this...and I have the galaxy nexus extended battery in!!!
Sent from my SGH-T989 using xda premium

yeah that's rather bad. i would put on average that our phone would last 4+ hours display on screen without the use of JD and other stuff.
I would say voice uses more battery than display on.. but barely... like 1.3 : 1 ratio in use voice : display.
Your android system looks a bit high too. Maybe a fresh wipe and install would help things.

Dude.. 22hrs? I need your current setup lol that's a decent battery life i would be happy with that!

it's not your signal, your signal is mostly green when in use. and as you can see the cell standby and stuff is a small %. but yeah try a different rom.

4.0.4 battery discussion

It seems we are having mixed results with battery. 4.0.4 was supposed to fix the Android OS bug. Some are reporting excellent battery life while others extremely poor. Let's try and narrow this down as for me battery life is most important. Post your setup, screenshots, logs, whatever.
What have you done that showed improvement?
ROM cm9 alpha 2 clean install
Kernel fd02
Modem fd02
4g on
Wifi off
auto brightness off
Overclocked to 1.5 undervolted
Followed recommended battery saving options in faq
Android OS is still high but I saw improvements once I turned off auto brightness. The run before I got less than 5 hours total charge with less than hour screen time

4G ends about 4 blocks from my house, so I very, very rarely use it. Didn't use it at all today.

wifi on ...3g still on?
Using Cm9 alpha 2 fc 24 modem. Running very nice. However I noticed significant battery drain at work (no 3g signal) which happened with any rom I've used IF I don't turn on wifi. But this rom seems to keep searching for 3g signal (which kills battery) even if wifi is on. So now I have to turn on wifi and turn off 3g in order to prevent this (no big deal). Anyone else experience this?

Battery issues are be because we don't have e a legit kernel to be tweaked. Once that happens I'm sure battery life will go through the roof

Sent from my SPH-D710 using Tapatalk 2 Beta-5

Although i am not on ICS, i did notice a difference in my battery life when i went from FC15 modem to FC18, 22 and 24. For me battery life went down a bit.
Running Stock Rooted EL29 ROM/Kernel. Im now on FD02 and about to test out FD05.
So far FC15 has been the best, FD02 is working well.
FC18/22 were the worst for me as far as battery life and data speeds.
For those of you running ICS and having battery issues try the FC15 modem for a few days and see what happens.

With wifi on I can get almost 5hrs screen on time

This could be a problem with battery calibration.
Sometimes this phone thinks that the minimal (0% battery) voltage is 3.7V, while in reality, it's closer to 3.5V.

This looks normal for epic touch on wifi:
battery percentage ~= 100 - (screen on in minutes/4) - (phone on in hours - screen on in hours)

Guys I have calibrated two different batteries, I still drain 1% a minute even on gingerbread, I think I need a new phone, I have insurance but I don't know if they will give be a new one..
---------- Post added at 06:21 AM ---------- Previous post was at 05:57 AM ----------
I highly suspect this is the infamous Samsung charging port issue which has caused many other owners to experience intense battery drain. This was an almost overnight experience out of the blue, so I know it isn't battery calibration.I just need to convince Sprint.

Exceed 2 hours???

Anybody find a nice trick pass that screen time barrier??? Most people reach 2 hours and it seems no one can pass that barrier.
The only thing you can affect and make better is when the phone is off.
The farthest I've reached is 2h 30m on a light day.

I check everywhere about exceeding 2 hours and everyone is like oh this rom is that and gives me 4 hours with such and such and such kernel

I get 2 hours on wifi or 4G LTE or just plain 'ol 3G.

I turn my 3G data / wifi off whenever I don't use it. I usually get over 3 hours, not using an extended battery.

I was on skankwich and the samurai kernel at the time. Currently running jelly bean and samurai but there are issues with deep sleep for some reason.
Lazy governor fiops IO scheduler I used voltage control to under volt and control the CPU. If you have been using interactive then that may be why your battery drains.

Can you prove it was black?
Anyways, I had AOKP B39 + Franco 196, and it was amazing. 5.5 hours sometimes, usually 5 hours as the 2nd post shows.
Usually never had data turned on for more than 30 minutes overall, but Wi-Fi was on for most of the time. CPU speed was at 192-1036 MHz. Never really got around to UVing, mostly forgot about it cause I got such great battery.

I get 3+ hours easily on my GSM nexus, I've heard that the battery life is worse on the Lte version.

3 hrs of screen time still 40% battery gsm running jelly bean ROM from ROM manager

Did I mention I use Verizon.
Of course GSM gonna stretch.

From 100% to 0 using continously, it takes my phone around 4/30 hours to discharge

And I am not using any apps like juice defender or any tthing else to help with battery life. I'm just using the crap out of my phone. Not once did it even get so much as warm. I have been around android since the G1. I must say this is the best rom and phone combo as far as battery life goes. That I have ever used.

Lmao this phone wouldn't even last that long if it sad in airplane mode that entire time. Post actual screen shots with the corresponding screen on time, and any other details. Unless you have an extended battery, this phones average screen on time is 3.5-4.5 hours with the best setup. Which means you barely even touched the phone in that 4 days.
It's fishy enough that the screen on bar from that picture is missing..

If this is an extended battery, more power to ya man. But that's not usually something to brag about as that's what an extended battery is meant to do lol.
