Hey all, So I had restored my iPhone 6 as new and was enjoying a great battery life. I had installed Skype but had lot logged in till 2 days back. Suddenly 2 days back my battery went for a toss and I was clueless as what had happened as I had not changed anything nor installed anything new. Luckily I went to AppStore to see the reviews and found another user saying that it kills the battery life. I was like it's quite unlikely but no harm in trying and after logging out of app guess what my battery returned back to normal. So I can confirm that Skype hogs battery like anything and in case you guys are having battery issues then try logging out of Skype and recheck.
