Battery/CPU killer (possibly iOS 11 related) – Tile - Find lost keys & phone Review

After several weeks of dramatically reduced battery life and general poor performance of my phone (iPhone 6+) and many attempts at tuning the system to improve matters I just assumed that my phone had reached the inevitable point where it simply couldn’t keep up any more with the latest operating system, iOS 11. This was somewhat surprising but I resigned to buying a new phone. Then yesterday I took another look at battery usage and saw Tile right up there at the top with 20% background usage!! It was in the list previously but never this high. Right away I disabled background app refresh for Tile and turned off Bluetooth in the Tile app settings. After a day now it’s like I have a new phone again. No more massive battery drain. No sluggishness. I rarely give reviews but I felt I needed to draw attention to this problem. Until the issue is identified and remedied I shall have to keep Tile disabled. I see at least 1 other person with similar issues here.
