Your problem sounds like mine... I would get 20-30% drops in charge after turning my phone back on! I eventually exchanged my GS3 for a new one after experiencing the same problem. I, too, was frustrated after following all the recommended steps I read on the forums, including using Juice Defender, etc...
With the same apps and settings on the new phone, it's performing as the old phone did the first week I got it. Bad phone? I don't think so...

The culprit?

I think it was my phone charger in the car... I bought this "universal high-speed" charger online, and it used to make the battery run very hot when charging.

The very helpful sales representative that exchanged my GS3 confirmed that there was likely something wrong with my battery... I think the charger damaged it somehow. I just ordered a Samsung branded charger that is "compatible" with the GS3, and have only been using the charger provided... I'm hoping that it was a faulty charger that I was using in the car. Incidentally, I won't be using that charger anymore!

Hope this helps someone out there!

this is why i only buy OEM chargers. either carrier or phone manufacturer.

Turn off your NFC! I found that leaving NFC and the S-Beam off gives the galaxy s3 superb battery life. Turn off navigation also. Turn these features on only when you're going to use it.

Are you joking? The battery is not likely to be the problem. I'd bet money on a hungry app. At the very least, some diagnostic work is in order first.



Are you also joking? I am NOT rooted, have data, Wi-Fi, and all 3 GPS services on 24/7 and I can easily get through an entire day! Check your apps.

Most people don't realize that free apps are some of the biggest battery munchers due to poor coding and ads.

My phone suddenly started dying very quickly. It turns out that the Google+ update was at fault. I uninstalled the update and the battery life returned to normal.

How do you "check your apps"? because if you talking about app manager i did that. I have wifi, location turned off & display turn half way down and it still drains at night/when idle. This just extremely disappointing coming from an 2 year old used to hell iphone 4 that used to last a whole day in a half without charging easily with normal use (2 days if didn't played games/using apps)..

even if i don't use the s3 much that day, I still have to charge it at the end of the day.

I had this problem too. Battery is fine in the office while using it, horrible at home at night while powered off. I fixed it by turning off 4G LTE because where I live, there is no LTE which kills the battery as it perpetually searches for it.

Here's how:

I have an easy answer you ... Charge your phone at night

 

[saintforlife]

Update - I did a factory reset of the phone. This time I didn't bother disabling any of the AT&T bloatware apps. I installed all my apps back except Juice Defender. I wanted to keep the phone as stock as possible and didn't want any apps changing any settings, so I didn't bother with JD.

I've to say the battery life has been great since the reset. The phone lasted almost two days on a single charge! Granted I didn't use the phone much during these two days, but it is still pretty good. I am just happy that I have a phone that didn't die over night thus taking my morning alarm with it.

I will continue to monitor over the next few days and see if this battery performance lasts. If not, the phone is going back to AT&T.

 

[funkylogik]

can you try disabling the bloat again to factor out that as the cause mate.
id like to see someone like Jerry from the podcast do an article on these juice defender type apps on modern phones... seems like JD was doin somethin bad in deep sleep..

Yeah it does matter, you should change them to 1 hr.... One app can cause your battery to deplete very quickly if it's syncing too often

How do you change the frequency of the syncing? ?

Now I couod be wrong, but I've heard to never use those el cheapo aftermarket external chargers because they could charge at a different level and fry your battery. And they don't always output what it says they do because they are so cheap. I've always gone with the manufacturer's chargers and never had a problem:thumbup:

Should I be concerned? I'm not liking this battery life. Didn't last me all day. My iphone gave me about 3 more hours than this! I used it moderately...

Thsts not a fair comparis. Your iPhone didn't have true multitasking (apps saved in state is not true multitasking). An Android leaves proceeds like facebook running in the backend and other apps that use the radio. How many days have you had the phone? Is this indicidive of every day? Battery life varies widely from day to day. If you're not happy with it consider an extended life battery. You can also see what other apps are running that consume radio.
