I just recently upgraded from the 6s to the 7 Plus this week. I love the fact that the 7 Plus has such a larger battery but it seems like it's taking forever to charge. I've never timed it officially but I'd estimate my 6s would charge to full in about an hour and a half. My 7 Plus is taking that long just to get close to 50%. Taking a little over 3 hours to get to full. Is this normal? I've owned every iPhone since the 3GS and have never experienced charging speeds this slow.
