iPhone users, don't update to the latest iOS 11.2.2 for the time being

IO.Hazard · 11. Jan 2018, 05:46 PM

For a number of iPhone owners, iOS 11.2.2 is throttling performance by as much as 50% (depending on the model).

Although Apple even warned users in advance the patch could have a performance impact in some situations, it was not expected to be higher than 2.5% in any situation. So are the big drops the consequence of an error in these mitigations or a problem elsewhere in the update? In any case, it will be better to wait until a new iOS version which corrects these issues is released.

It's been 3 months, and Apple has finally released iOS 11.3. One of the most important additions is that you can finally disable battery throttling, giving the users control over whether Apple’s performance safeguards are applied or not.

"In addition, the power management feature Apple is using to dynamically control maximum power is now presented as a toggle which the user themselves can control. Also found in the “Battery” menu, it’s now a switch that can be shut off if you prefer. Those with an iPhone 6, iPhone 6 Plus, iPhone SE, iPhone 6s, iPhone 6s Plus, iPhone 7, or iPhone 7 Plus will be able to control the setting; the power management is not currently applied to other iPhones or iOS devices".
