Is this normal for a Samsung Galaxy S3 battery?
So I've had my S3 for 2 months now and I feel like the battery is getting really weak. I've been using my phone today for 5 hours with lowest brightness, power save settings on, Bluetooth, GPS, NFC, and auto sync off, and I'm down to 48%. I've been using wifi (my data is turned off) and all I've been doing is surfing the web, using the tumblr app, and I played a game for like 10 minutes. Is this because I've been using my phone too much? The battery goes down 1% every 18-20 minutes when on sleep/stand-by mode. Is that normal too?
