Wow. You are who? Is Apple experimenting with Bots now?
You aren’t having a problem, so the rest of us are idiots or lazy sots and obviously doing something wrong?
Five minutes of Googling will reveal that many owners are experiencing this issue after installing IOS 11.0.3. I understand every major IOS release has experienced battery issues on a minority of devices, sometimes due to 3rd party apps on those devices. The litany of generic fixes is well known and well publicized… but they have had no effect on this bug on my iPhone 5S. You don’t seem to be offering any help.
You have an Apple Store next door? Mine is 150 miles away. Not that it would help; when Apple understands the issue, it will be resolved with a software update.
Apple extensively tests each IOS release. It would be most surprising if a large percentage of device owners were experiencing an issue as severe as this battery drain issue. If Apple knew of this issue before release there would not have been a release. I’m confident it is not a conspiracy on Apple’s part; they don’t like bad press.
My advice stands. Unless you absolutely need a fix in 11.0.3 (eg, 3rd party screen issues) SKIP THIS UPDATE. Who needs the hassle?
