I had been running rooted 4.1.2 on my sgh-i747 for a while but I decided to upgrade to 4.2.2. After I tried a few roms i settled on JellyBam. The battery life has since been horrible. I am a fairly light user, and after a full day my battery was always around 75%. After 4.2.2/JellyBam I'm lucky to see my battery above 50% at the end of the day.
The battery stats look normal, I have most of the extra battery-draining features turned off, but my battery life is still pathetic compared to 4.1.2. The battery drain was the same when I tried out the latest MIUI, but I haven't had any other roms installed long enough to test their battery life.
Any suggestions?

Flash a different kernel and check the thread of said kernel for battery saving settings. I'm on 4.3 and usually sit at around 60% after an 8 hour work day and moderate/heavy usage.

i have flashed multiple Roms, and i will admit i have never went through with the FULL battery calibration, but one thing i have gotten after each rom/kernal install is, after charging full, and wiping battery stats, it seems with just little usage my gnex drops so fast, even with screen down, on wifi, just texting...i can literyly watch the battery drop.
is this normal since it has not been fully calibrated? if i let it completey die after wiping battery stats, will the battery drop significanly slower? i has tested this with both batterys, ext, and standard
THIS is my ONLY gripe and the ONLY reason i would return it..
Thanks..
If you're basing your battery off of the first few discharges after a rom install.. it is bound to be pretty bad. You can just go from full to empty and then charge to 100 to calibrate it.

That doesn't seem normal. I'm getting as good battery life as you can ask for with this giant screen. I recommend checking out the android revolution thread in the development section. Mike has posted a few links to threads that really detail how to maximize battery life. You may see your battery life increase after a week or so of usage. Good luck.

Hi I have: HTC Wildfire with CyanogenMod 7.2.0-RC1
In about the past 2 days my battery life has dropped considerably with the phone not lasting more then 12 hours, as opposed to the previous life of 2-3 days.
I charged it too 100% last night and this morning when I checked it it was at 20%
I have not installed any new apps, my screen usually runs on low brightness and the data connection only running on 2g/Edge and I have changed no settings lately.
I tried a battery stats wipe, no change.
I remember having that problem just after I flashed a new recovery.
It was about 80% before I sleep And when I wake up I find it 55%
I installed Sympfinity kernel and it really improved battery life.
now only 10% (sometimes less) are lost through the night.
Try Sympfinity kernel.

I Flashed CM7.2 RC2 it seems to have fixed the problem.

I advise you to install battery calibration from play store, sometimes after flashing a new rom, battery may be miss-read
tip
the battery life is also affected depending on the time you have automatic update on your phone because if you have updated very often it spends considerably battery not in use so the phone .. hechale a look at this and help us a lot of your battery greetings
Welll i used to have a similar problem on my wildfire,so i downloaded power max and used it on standard mode and used Go power master with autoswtching and other stuff...just before exchanging it for a Nexus, i had the battery to last around 40 hours with 5 hours of browsing, 3 hours of listening to music and 2 hours of gaming with heavy use of whatsapp and texting and 30-40 minutes of calling...previously my battery use to last only 10 hours...hope this will help you...you can also go up to ebay and buy an extended battery for just Rs.960 which is 3000mah...cheaper than the original smaller battery....link to the extended battery http://www.ebay.in/itm/3000MAh-Exte...4-HTC-Wildfire-G8-/140533335447#ht_1453wt_907
So i'm running stock jellybean 4.1.1 OTA (yakju) however i've noticed battery life isn't great, charged phone overnight to 100% its been on standby for 7 hours and is already down to 68% screen time on is only 3 minutes, is this normal battery drain seems a bit excessive for standby.
depends on what you have running and syncing, etc.
you gave us no screenshots or anything to base anything off of.
I just charged up my phone from a 20 hour run, almost 4 hours screen time broswing with wifi mostly... stock JB 4.1.1
edit: oh i forgot i am using franco.Kernel
On my Nexus battery life isn't much better than on your Nexus, It is normal or then my Gnex battery is poor again..
I'm using "takju" JRCO03C with it's own radio + kernel so all is stock and battery life is enough good, for me on yakju builds the battery drains much much faster than on yakjuxw/takju builds..
My Galaxy Nexus's battery stays 14 hours with not using it and then battery is left something 12% or less, and when I use my Gnex then I can use it like 2 and half hours and then the battery has too less life to use it... (when Clock Alarm is on, and Hotmail + Facebook notification enabled...)
Google Now is said to use lots of power, have you tried disabling that?
I am also getting really bad battery life since JB. I have the extended 2000mah(?) battery so this might be the issue although I have not had any issue with ICS, I got about 26 hours with this battery on ICS. Now on JB I will go from 100% to 85% in 2 hours and all I did was text about 10 times, no phone calls. Today I woke up at 6am listened to Google music going to the beach, at the beach did not use the phone except to check the time.
Listened to Google Music on the way home, got home at 6:30pm battery was at 31%. I did not surf, made one phone call that lasted 30 seconds.
This has been about consistent since JB installation. Everything is stock except for the fact that I am rooted.
I am currently conditioning my battery, when done Im going to remove facebook and see what happens. Also can we "freeze" Google Now? This so I can test the batter.
Thanks for any suggestions and/or ideas.
I'll chime in to say I'm also getting slightly worse battery life on JB. I'm mostly observing idle battery drain during the work day. On ICS it was a steady 0.5%/hr, on JB it is over 1%/hr. So before I could get away with not charging it some nights and it'd only lose like 3% overnight, but now it's more like 7%. The phone is stationary during this time so I can't imagine Google Now is contributing much. I'm not rooted, completely stock.
What are some options available to investigate this? BetterBatteryStats or apps like that?
Hi,
In the latest nightly of cm11(n5100) the battery drain has increased dramatically, I was wondering if it was a thing that happened to someone else, or even that I am I need to reinstall the rom.
Days ago, the battery lasted for 13-15 hours a day and now it barely lasts 2 and a half.
Thanks
Try doing a fresh install, let it sit for a day and don't install anything else. See if that changes battery life. If yes, then one if the applications you are installing is causing battery drain.

I tried to reinstall the rom but the battery drain doesn't change
Maybe i will install the official italian update of kitkat to see if battery drain will change .
I got stock os with all the fancy stuff disabled.
My battery charges 1% per minute when between (0-85%) after that charging slows down.
It doesnt however fully charge it usually wont go higher than 97%.
Battery drains 1%/h in standby
5%\h listening to offline-music
Today I had 6h 5 min with 3:54 on-screen time ( starting from 93% down to 2%.
About the same for me but I can do a full charge in 45min coming from about 9%
About the same, recent CM builds are better. I'm considering the Nexus ROM

At first i thought the battery life was ok, then i switched to the nexus rom for a while and came back to stuck because i wanted my camera back. There is a huge difference in battery life as far as I'm concerned. Stuck OS burns way more battery when idle but then again it has a lot more bloat :/ so it's to be expected
I get awesome battery life. On rooted stock with third party launcher with various tweaks. Way better than my desire or Moto g or Moto x or nexus 4 ever were.
Agreed, all other roms besides stock get awesome battery life. I've disabled or uninstalled as many apps as possible and the battery still drains unacceptably fast at idle. If we could get a stock rom modified to get the battery life of a custom rom that would make this phone perfect for me.

I consider the battery in mine to be working very well and use ~33.3% every two hours with the screen at full brightness and constant touching for reading. So looks like its about the same.
Standby is ~50% used in 48 hours with wifi on and background apps using the internet.
That's based on the apps I use and whatever they're doing in the background to wake the cpu, use wifi, etc.
Stock rom with the 'fancy stuff' disabled as well.
