When did your battery life start to get better?

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.

(UVDLI6 JB) Sudden Battery Drain

So I am running UVDL|6 for some time now which works good (not great but good) and this morning I woke up to find my battery completely dead. When I went to sleep it was at a decent 55% now I highly doubt that without any use the battery just drops to 0%, So checked my battery stats and it says Android System at 70% use.. which is pretty high for an idle phone. Any ideas? Or any software I can use to pull out the culprit because Android System has so many subsets to it that it makes it really hard to pin point what causes it.

You will have to reproduce the problem, but try GSam Battery Monitor.

Reproduce the problem? Well I was a sleep so maybe ghosts were messing with my phone, I'll ask them nicely...

I think he means you need to put your phone in the same spot when you go to bed and see if it does it again. No sense in trying to fix a one time problem.
Battery stats were gone when you started the phone up I'm assuming. Good reception where you placed it?

Been happening to me on LI7 lately. Originally it was great on battery life, then all of a sudden I started getting insane battery drain from the Android System. I haven't really taken the time to diagnose it yet, but I need to. It gets really hot randomly sometimes then cools down and the battery just starts draining away really fast.

I saw someone mention deleting or renaming gsiff_daemon in /system/bin to solve this.
Theres a thread dedicated to the subject as well, though ive yet to actually go through it.
Anyway give that a shot and lets all hope they Completely fixed the battery issues in the final release! (Its not all from one thing in my experience with the leaks, but from multiple issues)
Sent from my SGH-T999 using xda app-developers app

Ill add my stock experience for reference as well as if anyone has a fix. I'm pretty happy with battery life coming from a Vibrant but what I notice is that usually there is minimal drain during the night ,however if I get an SMS the drain will be maximal.Like 30/40% Almost like the screen went on and never shut off but it doesn't seem to be the case. This is on the stock messenger App. If I don't get an SMS it will usually drain from like 99% to 96% roughly. Didn't mean to threadjack OP.

Have you tried running Better Battery Stats to see why the phone isn't sleeping?

Yeah battery stats were probably from when I turned the phone back on...

Battery Drain Problem

So I bought my ATT GS3 out in Los Angeles this summer and then I returned to New Jersey to find that I have horrible battery life. It was not right away so this could be completely unrelated. As of right now my phone is at 75% and I let it drain while i was sleeping for 10.5 hours. I have tried several different roms which are usually good the first two days and then after that the battery life is bad again. I thought it may be some application I have installed so I removed a few of the ones I remembered downloading since I got back to NJ. I also updated to the latest radio ending in H9 because I was two behind when I checked. I have attached some battery information below. Any help anyone could provide would be great. I have tried Juice Defender which did save some battery life but it also caused a problem where I couldn't use the internet for 10 seconds after I wake the phone.

U need a Rom with cell standby fix
Sent from my SAMSUNG-SGH-I747 using xda app-developers app

I thought the cell standby problem only effected the international GS3? If the cell standby fix was the problem then I shouldn't actually be draining that low right? Something must be draining the battery then. Google maps is probably draining the battery but how do I stop that from happening?

No its not just international and it is cell standby using almost 10% battery

Just another observation. Battery tends to drain faster if you leave it in your pocket. If you flash a rom, you might have to calibrate the battery stats. I only lose 1% every 2 hours overnight if I leave it on a cold surface.
Sent from my SAMSUNG-SGH-I747 using xda premium

So I have tried a few different roms and I'm still not happy with the battery life. I calibrate the battery after every rom installed and I usually keep that rom for atleast 2 days to test it. Right now I'm on AOKP. If the phone is on standby whats the general %/hr? When I go to sleep my phone drops from 92%-75% for about 10-11 hours (on desk at temp 60F). By Apocalypse487's response I should only see a drop of 5-6 % over night when I see 17%. Am I supposed to me losing this much battery life over night? To me I feel like I barely use my phone. Today wasn't too bad with 1 hr with screen on and about 1 hr in calls. I made it about 1 day 1 hour 36min on battery. My phone was sleeping for about 23.5 hours. Is this the typical battery life or is something wrong with mine? Tonight I'm going to try juicedefender and see if that helps.

I'm using ParanoidAndroid based off of CM10. Version 2.16 of PA gave me the best battery life. Try that. Certain Roms have better battery management, but that probably depends on the kernel. PA uses stock.
Sent from my SAMSUNG-SGH-I747 using xda premium

I'll give ParanoidAndroid a try and see what that does. So Juicedefender ended up making it so I only lost 1% over 9 hours. Thats pretty good. Way better than I wanted. So what could be draining the power over night. Is it because my data is on all the time but shut off when using Juicedefender?

I use Trinue 2, and I use an app called Go Power Master.
In GPM you can setup options that will turn off mobile data/gps/wifi when the screen is turned off, will automatically turn them back on when the screen is back on.
Those things little things I find can make a big difference for the battery to last throughout the day.

It's as Sianspheric says, common things like gps, data, and wifi uses power. I just started using Juicedefender since my friend told me it helps. Also download battery calibration. It's a root only app. Don't let your device discharge completely. It's bad for Lithium Ion batteries. That will clear out any bad data from Samsung.

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.

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!
Sent from my SAMSUNG-SGH-T989 using xda app-developers app

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

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)

Randomly battery life dropped

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.
