How can i make my samsung galaxy S3 battery life last longer?

Chirag, that's how Juice Defender works. It saves power by turning the radios off, and only turning them on when you schedule them to.

Can I do something in free version that I keep receiving whatsapp messages while juice defender is still enabled?
Today when I was out of charger so i had to enable it, saved my battery up to some extent but didn't like that my urgent whatsapp messages were not coming instantly. I know the reason for it. I just want to know if there's any way to circumvent this.

I'm using the free version of Juice Defender and my email is set to push so Juice Defender is not stopping emails from immediately coming through. I know this for a fact because my phone alerts me to incoming emails as quickly as they appear on my PC.

Wait? 22 hours on 50% battery? If that's anywhere close to typical I'm not sure what your concern is. That's about as good as you could possibly hope for.

As said, this was with me only using it for 26 min since I interpreted instructions that it should be idle, but had to use it somewhat. Besides this it was also not typical at all since I had it not charging during the night, which I normally do.

According to sources standby time for s3 is:
Stand-by Up to 590 h (2G) / Up to 790 h (3G)
Talk time Up to 21 h 40 min (2G) / Up to 11 h 40 min (3G)

Which is 32 days (!) in my case. Yes they probably mean not having any apps that are syncing, perfect conditions, strong signal etc, but still you are saying that 22 hours, 26 min out of those being when I've actually actively used it, is normal? That's a VERY big gap to 790 h. I guess the good news if so is there's nothing wrong with my machine or my hardware/ROM/setup/apps. GSM arena seems to verify that this is normal for normal usage.

"Samsung Galaxy S3 running on Jelly Beangot an endurance rating of 50 hours (7 hours more than the ICS Galaxy S3), which means you?d need to charge it once every 50 hours if you do an hour of 3G talking, an hour of video playback and an hour of web browsing each day.

Anyway, here are screenshots from today when I've used it as I normally do, except I had brightness fixed at ~45% when normally I tend to forget it at 100% (yes I know what auto-brightness is). Please tell me if I can stop OCD:ing about my battery life being abnormal.

I took this when I arrived at work. I had checked gmail once, alarm had gone off once unlocking screen, watched 44 min of video.

Then I watched another 20 min of video, did 5 min of RSS reading in feedly. After that it was idle for 4h 30 min while working.

Then on the buss home I watched 10 min of video, and spent 7 min in feedly just reading RSS. On the buss it reached half discharge:

So if I follow this correctly (and I only have time to glance at it right now), you're at 50% after 10 hours, which would give you 15 hours with 25% left, assuming the same usage pattern. I really don't think you can expect much better than that, especially on 3G the whole time.

Advanced beginner (@ best) noob here! Been searching for a solution to my problem that was borne out of the same predicament that this thread was started upon so wanted to share what NOT to do. Do NOT (as I did) delete this file: com.android.providers.calendar. I went searching for the top things that were accessing my wake screen and deleted the top 4!
There's a reason that the Olympics give medals to the top 3 and I should have stuck with that model! Ugh! :'(

PS-If anyone has any (SAFE & easy for the computer semi-illiterate) ideas on how to fix that, I'm all ears (or is it all eyes?)
PPS-I'm on a Verizon GS3 (SCH-I535) running 4.1.2
PPPS-Though its not really apropos, I tried stuff from this post on androidcentral & did not help

These are my results a week ago. My battery is pretty good.

hello, thanks for having me ive been following this thread and ive gotta say it has some good advice.

I wonder if i might ask a question ? Ive got an s3 mini and i only get 7 or 8 hours out of it, MAX. ive got the screen on min, fb and email down to every 30 min - ive just stopped malaware bytes being "always on", im hoping that will stop the battery going so quickly?

Its a replacement battery from ebay, but to be honest, its just the same as before ?

:'(

all these people moaning about 22 hours an that ... wow.. i dream of 12 hours, let alone 20+

Hello and welcome to the forums!

I've got an s3 mini and i only get 7 or 8 hours out of it, MAX.

Your usage does alot to determine your battery life - if you'd like some help, fully charge the battery, let it run down to around 20% and then capture the three screenshots from the Battery view (main, History details and Screen on time) and post them here.
