    Hi. Have you turned your phone off and back on again since you applied the update?

    I applied the update to my S3 Mini last weekend and ever since then I had the battery draining problem. I'd have to leave the phone on the charger overnight then at least the charge would last til I got home. Yesterday I experimented to see how long the charge lasted and, sure enough, the battery went flat. I stuck it back on the charger at about 3am and it was recharged when I left for work this morning. Its now 6:30pm (I'm in Australia) and the battery still has 85% charge!

    I'm guessing the phone need to be restarted for the update to work properly. (I remember reading during the update that I should restart the phone but I assumed the restart it did during the update covered that. But perhaps not.

    Anyway, I hope this helps :-)

    Your screen shot is showing a total of 22h 19m on Battery. This is really great battery life. I really don't see a problem.

    Another alternative app:
    "Wakelock detector"
    You can monitor what is draining your battery when it is idle

    I also face this problem. My battery drains very fast. I have tried to find out which apps use the most battery but found nothing. I just bought my phone for only 2 months.

    I shut down all non-essential apps, put the thing in battery saving mode, replaced the battery, charged the battery overnight with the phone OFF, and I was *still* having battery drain problems. I read on another forum that replacing the SIM card helped someone else...and I did that today and...VOILA! It worked! Now I'm doing my happy dance.

    Mate. I'd recommend trying a different usb cable. The stock Samsung cable has only 4 contacts inside the micro usb. BUT if you get a different one (I used the usb cable from my HTC one) it'll most likely have 5 contacts. I think this may improve charging times. Give it a try and get back to us and tell us how it went.
    Cheers!!!

    I read this on another thread about this problem. Do you get another SIM from your carrier? Mine is AT&T, will they do that?

    Assuming that your variant uses a SIM card (I've stopped trying to keep track of which models do and which ones don't), you should be able to get a replacement from any corporate store.
