I've had my Galaxy S3 for just under a month now. I love it. Easily the best phone I've ever had, hands down. Just as of today, however, the battery just started to drop and drop and drop. I unplugged my phone before leaving for work and after my 10 minute commute to work, I got into my office and battery was at 97%. Didn't even touch my phone before home and work. Hmm. First strange sign. Now, that was at 8.30 am. Now it's 12.30 pm and it's at 50%. What is going on here?
