I have had the phone for 5 days and with fairly light usage, I am still not getting good battery life. I turn off all data and wifi when not using it and screen on time is below 2 hours.
Below is a screenshot of my battery life.

It doesn't get better...get used to it until its fixed in an update , along with the other big issues.

By about the 3rd day it seemed better. But it's also difficult to gauge because the first few days you're bound to toy with it constantly.
Until there is an empirical way to gauge usage, like an amp meter attached to the phone - it's all perception imo.

In the top left you have three things running in the background, im assuming constantly. Uninstall them, especially the battery percentage since you can look that up easily on your phone

Do yourself a favor and try aokp milestone 1 from rootzwiki , and also download lean kernel 1.1.1 on xda. Use interactiveX governor for kernel. This is the exact setup I am using now, and have been for a few days and have been getting insane battery life. Hope everything works for you.

Last time I checked lithium ion batteries don't get better after a few days and yes there are software fixes for battery life and bugs..

You really have no idea what you're talking about. First of all, it will get better, I won't bother explaining the science behind it considering you can do your own research, but it will, also, it can't be "fixed." Just like they can't make it an 8 mega pixel camera in an OTA. You can get it much better by doing custom roms and thigns of that nature.

It got better when I turned off vzw backup and google +.
Best I got is 16 hours bone stock just an extended battery. Worst I got was 4 hours(screen was on the whole time) watched 2 movies before I plugged in. I average around 12 hours from 100% to 20%.

First off, it's hard to tell by your screenshot how good or bad your battery life is. You're burning approximately 10%/hr, but maybe you had your screen on or were surfing the internet for a portion of that time. Anything that involves data transfer will kill your battery faster.
I got my Galaxy Nexus on Wednesday, and I've had great battery from the start. I calibrated it by letting the phone's initial charge die down to zero, and then charged it all the way up to 100%, and then used the Battery Calibration tool. I drain between 2-3% hour with light use, but can obviously drain much more depending on what I'm using the phone for.
That being said, for those on this board who think an OS upgrade is going to fix the problem, I highly doubt it. I have a reasonably poor cell signal (averages around -95 dbm), but still get solid battery life. Given that we were all issued phones with the same software, if you're experiencing incredibly bad battery life, I'm going to point my finger at the hardware. It just doesn't make sense that some of us with 4.0.2 get great battery life, and others do not. You probably have either a bad battery or a bad phone. Now, I'll probably get called out for saying this, but watch all the posts that follow when the update releases, when people still have poor battery life.
This is my 3rd Android phone (Incredible, Charge, GN), and every one of these phones has had poor battery life. On average, if I'm playing around with the screen on, I'm draining upwards of 10%/hr, if not more. But if you properly calibrate the battery - which is VERY important - you should easily be able to get a full day's charge out of your phone.
There is a post on XDA about the 13 steps to proper battery calibration. Once I followed it on my last phone, my battery life went up at least 50%. You have to let the battery drain to 100%, then bump charge a number of times, then use the battery calibrator.

Try running without JuiceDefender. Constantly toggling data on and off (or wifi on and off) actually hurts battery in almost all cases.

Your results may vary, but when I used Juice Defender or Green Power on my Droid Charge, I nearly doubled the battery life. I haven't put it on my GN yet because my battery life is much better than what I had with the Charge.
No using JD or anything like that. Just the the phone do its thing. I don't even open the multitask button unless I want to switch between apps.

Gotta be a software issue with the battery.
Just this past weekend in Wash DC. Very strong 4 G market.
I had it fully charged off charger. After 7 hours without touching the phone even with google plus sign out, the battery went from 100% to 54%. It's like the phone was active a lot without me even touching it. No SMS/mms either. No emails either.
Know. I did same thing and put it on airplane mode with it 100% charged. After 7 hours on airplane mode it was at 98%.
So it's gotta be an operating system issue.
I tried it on wifi instead of 4G mode. And battery drainage was down to 72% after no use overnight.
Hi,
I have a GN extended battery, and I've noticed it's been draining much faster as of late. I used to get 2 hrs of screen time, now I get just over an hour. I'm thinking this is the battery itself, since I've switched kernels and ROMs several times, with the same result.
Is there any way to test the battery for quality? Other than my subjective opinion that it seems to be draining faster, is there a reliable way to test whether its lost its ability to properly drain?
Flash Stock Rom and enable automatic brightness. If you can get 3 hrs of screen on time everything is normal.

Best thing I have found is to totally drain battery to the point it the phone will only slightly vibrate. Remove the Battery. Put the battery back in and then fully charge with the phone on charge mode to 100 percent. Unplug. Then plug back in a few seconds later for fully charged to reappear. Done. Really helps to do this once every month or two. Credit to someone on another forum for this tip. Turning off data when not in use and low screen brightness will substantially increase battery life. No syncing, bluetooth or wifi will help. An app called GSam battery monitor will identify apps that suck battery. I use longevity by trend micro to shut my data off.

Fully draining a lithium ion battery will significantly decrease it's lifespan. Any positive effects you see from this are probably not measurable, or scientifically reproducible. Your other tip is solid, disabling data (or using an app to do so) greatly increases battery life. As well as turning down the brightness.

Had no idea this practice decreases lifespan of the battery. Good to know. I thought the this resets the phone ability to recharge the battery to the fullest. That's what I thought. I seem to be getting some benefit.

Typically get ~5 hours "screen on".
That could be 12 hours or 2 days between charges.

Battery lifespan for lithium ion batteries is measured on how many cycles its been through (hits 100%). If you go from 90% to 100%, you just used up a battery cycle. Even 99% to 100% counts as a cycle.
The method you described in your earlier post is for conditioning your battery, it works on older batteries but is not needed for lithium or poly lithimer batteries.
Tips for battery life, disable radios and keep screen dim. A dark wallpaper helps too, white screens are a battery drainer!

Get a app that disables other apps that start up on system boot-up or other events. Autostarts its a good app I use. As you all should know dont use app-killers unless u know how and when to use them (READ). Like said keep ur screen dim or on auto if u have that issue like me were ur constantly going in n out at work and find ur phone too dim for daylight. The darker your themes the better battery life. Remember that ur screen is one of the top (if not the top) battery drainers. Data, wifi, gps, bluetooth, auto-sync, running widgets, live wallpapers...if you dont need it on or could live without it, then either turn it off or get rid of it.
Also like said before, lithium-ion batteries dont suffer from memory effect like older rechargable batteries. If you could avoid it, dont run ur battery all the way down. Be free to charge ur battery as often as possible and that way you extend the life of ur battery.

Use the lowested sync frequency setting you can or manally sync. Wifi tether guzzles juice. Live wallpaper is a killer. Make task killing a subconscious reflex. The smaller the number is next to "running in background" also makes for more time away from an outlet. Of course these may not help any one else, but it works for me
Fully charge 2 batteries. Unlimited talk and text. True story

I run the ParanoidAndroid 2.51 rom (10/24) with the KKO kernel and it goes pretty good so far. It may be the first day of using it but I will expectedly average 20hours of use on it. (using the live wallpaper phase beam the whole time). Used the wheatly governor with SIO and changed the max cpu to about 1028 so its only using 1Ghz. (seem to get decent battery life)
Hi everyone,
I noticed that my phone often gets uncomfortably warm during use.
I've been using GSam battery pro to look at the battery temperature, and it usually runs between 80 and 100 F.
If I'm using a browser or using it any meaningful way, it usually hovers around 100 F.
Interestingly, the battery also seems to drain more quickly when it gets hot. I'm not sure if that's related to the more intensive cpu usage at that time or the direct effect of great on battery life.
Is this level of warmth normal? Have you all experiences anything similar?
So far, my battery life is shorter and heat is greater than my previous galaxy s3.
Thanks.

This phone's battery doesn't do so well with temperature. When it's hot, as you already noticed, the battery starts draining faster.
Are you running the apps for a long time (without turning off the display)? That could be a major cause, or using the phone while it's charging.
Try to keep this phone in a room-temperature place (not to hot or not to cold), I've noticed, when I was swimming on a hot day, my phone was extremely hot without me even using it. It's weird but try to avoid that, put the phone in a bag or under some clothes!
Hope this helped!

I'd suggest rooting and installing a custom rom. My battery life is better than with the s3. So is the phone gets hot issues.

Go to settings, more, then battery... Take a look what using up the battery. It could be an app or the phone trying to read the sd card.

Thanks for the tips. Sorry for posting in the wrong forum.
I'll try dimming the temps.
I've already looked through battery stats and wakelocks and used Titanium backup to freeze a ton of the junk programs.
I'd love to try a custom ROM but unfortunately need the wifi calling (my work has poor reception but great wifi... )
Hey guys. So unfortunately better battery stats stopped functioning. Basically when I first got the phone the battery life was pretty good, close to 5 hours screen on time, decent standby battery life. Recently within an hour of screen on and phone off the charger for about 3 hours it could easily be at 50pct. I am currently running wicked version 6 with stock kernel. I haven't downloaded any new apps that have exacerbated it and seems to deliver about the same battery life on a clean install of a rom before restoring all of my apps.
Anyone else experience this? I've tried both my stock battery and another battery with the same results.
Auto sync off as always. No clue why the crazy drop in battery performance and light on the subject would be awesome.

It's in your mind. Wiping the battery stats did absolutely nothing for you. Guarenteed.
You could have a battery that went bad. Take it out of hte phone and look at it. Is it bulging anywhere on the surface on either side?
If so the battery is bad. Replace it.
If not, it coudl still be a bad battery. See if you can find someone else with an S4 who will let you test their battery for a few hours.
Also, try a full wipe and reinstall of the rom. And restore your apps in small groups over several hours. See if battery life suddenly suffers after installing a particular app.
You could could have a messed up setting in the ROM, a rouge app that isnt' showing up on BBS, a bad battery, etc etc etc.

I noticed a pretty significant reduction in battery life since I bought the device. I see people getting 5-7 hours of screen-on time; 4-5 days idle time, etc... I could easily do that when I first got it but after around 2 months, I'm lucky to have 2 hours screen on; I'll drop about 10% over an 8 hour period on idle... I've tried on fresh installs of both TW and AOSP; adding none of my own apps and the results are the same. Stock kernel, Ktoonsez kernel, various settings, etc... I've also noticed that sometimes, say the status bar will tell me I've got 92% battery left; I boot into recovery and TWRP tells me I've got 97% left. That, to me, sounds like the battery is going south so I'll be trying a new battery here soon.
Thanks for the suggestions guys, I've got a spare battery been the same experience and similar to cheetoh, I've done fresh installs, no apps and standard kernel with same results. I'll maybe pick up a zerolemon and see if that plus a fresh start helps because this is ridiculous. My battery life used to be amazing I loved it, best phone to date for me, 5+ hours screen on and would spend the day outta the house, come home late night and still have 30pct. Now, it's at 30pct by 1pm... No difference in how I use it, if anything I use it less now. I'll try these things again and probably pick up a zerolemon... Usually this isn't a problem but I'm going to have to be spending a few long days without access to a charger during the day, and don't wanna get screwed. Anyway thanks guys.
