如果你已經係iOS 11.x. 你部機已經有問題 Upgrade 11.1 應該好過以前
如果你係iOS 10/11.x 部機冇問題 唔好Upgrade 住!!
The good news still remains: for many users iOS 11.1 drastically improves iPhone battery life. Something iOS 11 and its subsequent ‘minor point’ upgrades were shown to impact by as much as 60% when measured at scale by data analytics company Wandera.
Apple iOS 11.1
Unfortunately having published some of the many comments the author received on social media praising iOS 11.1’s battery life increases, the author has since been inundated by many more saying the update made either no difference at all or made their battery life even worse.
Furthermore this counterposition is gaining traction with @AppleSupport now being inundated with iOS 11.1-specific battery life complaints. Here are some examples:
“iOS 11.1 freaking sucks..it really kills battery life. We know you knew what would happen with this update. @Apple @AppleSupport” - source
“@apple @AppleSupport iOS 11.1 has ruined my iPad Air. It is laggy, scrolling stutters, battery life is bad. Please fix this mess. #iOS111 - source
“@AppleSupport my battery is draining faster than ever on the new iOS 11.1” - source
“Thanks I’m aware of battery saving methods,but the battery was perfectly ok until I upgraded to iOS 11.1 so is there an issue with it?” - source
“Horrendous battery drain on iOS 11.1 on 6s @AppleSupport. No problems until this update.” - source
“My phone dies at 41% battery life after upgrading to 11.1, i didnt even use it when its at 50% @AppleSupport wut r u doing?” - source
“@AppleSupport after upgrading to iOS 11.1 my battery drains very fast. I’ve followed battery optimisation tips but didn’t work. Any ideas?” - source
“Hey @AppleSupport my iPhone 6s battery life is horrible since the iOS 11.1 update. Please fix ASAP with the next update!!!” - source
“@AppleSupport my battery life on my 8 Plus was awesome until 11.1 update. Please fix this!!!!” - source
“Upgraded my iOS to 11.1 and my battery life sucks. I’ve had to charge my phone 2x today. What’s @AppleSupport going to do to fix this?” - source
“@AppleSupport PPS. Still experiencing battery drain with 11.1. #Notfixed. #Hotmess #tankingbrandreliability” - source
Curiously - and concerningly - what the author's seeing is the scope of affected devices has widened. While previously it appeared to be limited to 2016 iPhones and older, now iPad and iPhone 8/iPhone 8 Plus users are complaining.
In author's iOS 11.1 Upgrade Guide my recommendation was for users to hold off upgrading unless they specifically had existing battery problems. Sadly that appears to have been prescient advice since only those affected had nothing to lose.
Apple iOS 11 was found to slash battery life almost 60% in a test of 50,000 devices upgraded from iOS 10.3.3
So what should you do?
To reiterate: if you are currently experiencing no problems with your iPhone or iPad then stay where you are. iOS 11.1 brings nothing significant other than 70 new emojis and I’d suggest you really have to love emojis to gamble with your iPhone or iPad’s battery life to get them!
Meanwhile Apple is already testing iOS 11.2. This continues the company’s break neck pace of iOS 11 releases (personally I’d describe them as ‘rushed’) making it the sixth iOS 11 version since September 19th. Will this be the magic fix or will Apple serve up a stop gap iOS 11.1.1 in the meantime?
Whatever the version number, it’s time Apple got to the bottom of this for all affected users...
