3 days, 3 Hours, 24 mins of Battery life on my Epic

..

I hope this is actually true for me as well. I will upgrade once its fully stable.

uhhhh bull****. I have a siedo 3300 on acs with stuff undervolted and setcpu set from 200-1000 and theres no way in hell im getting anywhere near half that.

Why do I struggle to keep my charge for a day? Help?

Well sir you should sell your phone as magic beans because that is just a joke.
Theres no way i could get through 2 days with the seidi 3300 and wifi on the ENTIRE time and moderate usage. Just isnt happening so maybe you have some kind of config I dont know about but im thoroughly interested in copying your EXACT settings
This phone is useless to me if it isnt connected to the internet though for gtalk etc so if your data lasts that long because it just isnt connected to the internet at all that isnt any good to me

I tried the EE03 ROM for about 2 days and I went back to my EC05 SRF 1.1.1 because I'm running my 2800mAh Yoobao which I can average 2 days on using the full 100mhz - 1400mhz range of the Genocide Kernel....with EC05....the two days I ran EE03 I couldn't make it 15 hours...smh I don't know if I'm missing something but can I get a pointer to get the full capacity I know my extended battery can give me running EE03?

Data was on the entire time. Its really not that hard to do. Freeze DRM apks. Stop unneeded junk from starting up and launching upon connectivity changes and the like through autostarts. If you REALLY wanted to save data, turn data off at night while you are sleeping by long holding the power button and selecting turn data off. Stop syncing with facebook every 15 minutes. I don't sync or use facebook at all, maybe that is the magic bean. Don't have 30 widgets constantly running. Don't overclock. Brightness set low. Very simple things.
Edit: Also, properly calibrate your phone and battery. Turn off auto rotation and haptic feedback and things like that.

What was your screen on time?

Have haptic off and drm killed. I will check facebook. What startup killer do you use

I think it's crazy the differences of all "smart phone" battery life.
How can some people get 4 hours and others get days? I went through this with my EVO before exchanging it for my epic. Others have problems with their epic and none with the evo?
The hardware should all be the same so is it all androids fault?
They really need to fix this issue.

Which app was used to produce the graph in the first post? I don't think I've seen that one before.

There are a few reasons.
1) Some users just REALLY use the hell out of their phone. They have 4g enabled and are constantly taking calls or streaming music or browsing the internet or gaming on it.
2) Some users have no idea what they are doing. They enable 30 widgets that are constantly updating and pulling data. They have facebook and twitter syncing every 15 minutes. They have the brightness set from medium to high. There is nothing you can do to make a setup like this save battery life.
3) Some users KNOW what they are doing. They limit their widgets to necessary ones. They set the brightness to autobrightness or low. They lengthen the time between syncs for social media. They freeze the DRM files. They use something like autostarts to limit startup programs.
That is why battery life is all over the place. Also, people have completely different definitions of what "heavy use" or "light use" is. Add on top of all of this, that people are using different roms and kernels. Add on top of all of THAT, that some people undervolt their phones.

That is the stock gingerbread meter.
Gingerbread is awesome like that. If you go to Settings>About Phone>Battery Use and then tap on the small graph up on top, it expands to create that full screen graph.

I have noticed a huge battery increase too. I have not changed any settings on my phone to try and improve it. I got use to my 12 - 16 hours of use moderately. The only difference I made was not installing Advanced Task Killer and relying only on the stock Task Manager. I got 1d 8h of battery life on OEM battery. I will post screen shot when I get to my computer.

Power consumption "1% per 15mins" when standby

When standby conditions, it's drop 1% per 15mins. That means it should become 88% after 3hrs standby.
Is it normal??

This can be normal, depending on which Apps you have running, especially Apps that use some sort of syncing.

Had the same problem, look at the System Settings =>about phone => status => Battery status
Whats your status there? Normal is Discharging. Bad is Not Charging.
Not Charging means, that you have a defect in your USB Port.

Mine takes 8+ hours to lose 1% when phone is asleep

me too take 8 hours or more for 1% battery in standby mode.. test it last night already

How to make this performance?

I had this problem a very long time ago, it sorted it self out. But I use launcher pro and no widgets, have a live wallpaper and magiclocker. I don't use battery savers and my phone can last for two days with calls, sms, and browsing. Also wifi and gps are always on.
Just give it some time, I think the phone needs to calibrate, also in have auto brightness off and set to around 25 %.
I'm on kf3 if that helps to, goodluck

Just saing while reding here, Got my old htc desire HD and its same thing! about 8 hrs to lose 1% if i load it to 100% and screen of 8hrs it lose like 0,5 %
it has sleep mode? 250 mhz.all tasks killed. that is good battery 1230 mAh.
just saying, dont hate.

2 days!? One day is impossible for me....
My phone settings are same as you, but still cannot solve the problem.

Hey keung, did you get any better battery life? I'm experiencing the same issue when wifi is on. At night, if I turn it off, I can get about 1% 1,5% loss per hour, but when wifi is on it's about -1% per 15/30 minutes without any active usage.
I'm thinking it might have to do with the router... But I don't know what else to tweak on the router settings.

Guys this might be able to help, scroll down to the end of post 2 where it says "dirty guide for battery drain"

Thanks NoOne, but already tried most of the points there... and in any other thread about battery life. Not too much luck so far...

you defo have wakelocks mate
iam the same as everyone else about 1% every 8 -10 hours in deep sleep mode sometimes more
i do the following
#use titanium to freeze unwanted apps
#use auto starts to stop tasks starting at boot and other times
#use leo/checkrom v4 with siyah kernel
#use set cpu and set it to smartass v2
#use set cpu to make some profiles like screen off etc
#use set cpu to undervolt by about 50mv each cpu step
#turn off data when notusing it
#make sure apps like facebook only sync when i want them too
#make sure i go offline from facebook chat as it stays awake
#i dont use any widgets
#i use go launcher as my launcher
#pretty turn off all auto syncs like gmail and contacts etc i sync when i want to
of course you may not wan that sort of set up and you may wish to have data on all the time syncing all the time if so then expect more battery drain

Definately not normal. As people have said... hes wakelocked lol
looks like an iphone but powered by android baby!!!!

This is the solution
All,
I have tried a ton of modem/firmware combinations and I conclue that this has the greatest effect on batter life.
1 - I was on KK5 with KL1 modem then the KI3 modem then the KI4 modem and finally the KH3. Every KK5 and modem gave me terrible battery life. Not even making from 6 am to 7 pm! This is over several dyas of testing
2 - After experimenting with numerous combinations this the my current setup and I am getting a full days use 6 am to 10 pm and still have 40-50% left!
Now have been running this for a week and its verified. My data speeds are awesome (5-8 mb) and connections are rock solid. Here is the setup:
PDA - I9100XWKK2
PHONE: I9100XXKH3 (modem)
CSC: I9100XENJ1

There's about 2 solid hours of screen time there, I wouldn't consider that too crazy. Did your gf realize the screen was on all that time? Your idle drain doesn't look great, try better battery stats and/or watch dog (mixed reviews).

Watchdog is awesome, a must have! But yeah if you haven't calibrated you need to.

Wifi + screen on = loads of watching YouTube clips online while many apps using wifi open will definitely kill your battery.

Toggle background data off when not in use too. There are a lot of smaller power tweaks though, its a science and takes tweaking.

I had horrible battery life (10% every hour) as well until i flashed the latest Orange UK radio and all of a sudden my battery lasts for two days without charging. Note that wifi is off most of the time and u only use my phone to listen to music on the go, send txt messages all day long and at the end of the day i have around 70%+ battery left.

[Official] battery stats thread

Once we get charged up (and back down), let's see how the battery life in the S4 compares to the quad core.
Please make sure to include your screen on time, as that is the best indicator of light/heavy use.

pleasantly surprised
I can't believe how good the battery has been so far, 84% after 13hours (over night)
I am a light user. still - that is impressive for stock. I never got close to that with my OG Epic on stock which was usually 3% per hour.

1h, 3M Battery down to 76%.
screen on for 38 min, 33% of battery usage.

Heres mine on a first day full charge...

Not too bad for first day with moderate to heavy use!

This is heavy usage. Screen on time of 3.5 hours. Downloading Max Payne and a lot of apps. Downloading and listening to audio on Google chrome. Lots of Pulse usage. Games, YouTube, and 30 minutes of phone calls.
*edit* Bluetooth and wifi on all day long.

More information is better for those of us living vicariously through you guys. Remember to include screen-on time. Thanks!

Here's mine for the first full day. Should my cell idle be taking up that much of the battery?

one thing im NOT noticing here is Allshare Service taking up a high percentage in your guys battery stats...
on mine its been at 7-9% and i dont know why, i have something waking up my phone when the screen is off and it might be that... ive forced stop, but i check later and its active again, ive disabled the service and the Allshare play in the application manager but still comes back on... hmmm i think im gonna have to root and just get rid of that file, or freeze it or something

Question... Does having all the motion settings on effect the battery? Also does having the NFC and sbeam on hurt the battery?

I wish I could get some stats like that. The screenshots are while I was sleeping and 7% seems like a lot of drain for it just sitting there. Only thing on was wifi. Cell standby time on is always the same as the time on battery, is that normal?
edit: the phone now shows 79% battery left with time on battery of 12h 46m; cell standby the exact same; screen on at 9% with time on of 48m. I'm fully stock and running power save mode.

Here are my stats. I think the battery life isn't too bad so far but we will see.

are the battery stats suppose to reset when you restart the phone? For dinner reason my persist even after a reboot

No, they will carry over until you re-charge or change the battery.
I was going to make a thread like this, but it was already here! Here are my results after my second full charge and regular usage. The results are on par with my fully modified and decked out Epic. Of course, this device has a bigger battery, but it also has a larger screen. Between the hardware and software upgrades, I'm very impressed with the stock battery life. This includes wifi on at all times as well as signal w/data. Some motion features are enabled, nfc is not, and google sync is off (I use stock email). Now how much further can this be improved?? Remember not to be discouraged, Screen On times will vary depending on what the phone is used for. Showing pictures is much less battery intensive than watching YouTube videos.

Looks about right to me. You have to factor in I that you also have about 1 day of standby time and you were playing some games.
Try tinkering with your sync settings and WiFi settings and you may get a little more battery.

As some people to get 2 days of standby and 6h of display on in same charge? I've seen it on many screens on xda and other forums maybe they are using a custom roms? I actually mount stock 4.2.1.
What do you mean with wi fi settings?
Thanks

I have had awful battery life on 4.2.1. Its meant to give you 6-7 hours of screen time but I've had no more than 2. Really annoying and I'm sure I didn't get this on 4.1.2

So you have this problem too
I think so too It's a 4.2.1 issue, but I wouldn't install any custom room cause if it's an hw problem I can't back N7 with warranty...

I get around 10hrs of battery life (total actual usage)... with 2 days on standby
but i usually disable sync, only sync when needed. (make use of those widgets)
Avoid fancy widget, use stock widget if possible.
In battery settings, wifi off when it sleeps.
If you are using google currents, you have to disable auto sync, as it use up battery real fast.
And avoid push notification...
Push is the real killer, it requires wifi to be constantly on.
