Hubby just got this phone a year and 3 months ago. Just recently, it's draining the battery excessively. He's not a big phone user, doesn't text, doesn't surf net, etc. He uses it for the phone capability only. It's drained to below 30% daily for the past 2 days after completely charging it both days. Any ideas? I can't imagine the battery going bad after only a little more than a year.
