iPhone users complain iOS 16 is a battery drain, has other issues
Two weeks after Apple launched iOS 16, users continue to complain the mobile OS is sucking their battery power far too quickly.
Battery life tends to take an initial hit when new OSes are rolled out because updates to software and apps, as well as the reindexing files, photos, and other functions, taxes the processor, and thus, the battery. But over time, those background updates cease, and battery usage levels typically return to normal levels.
According to the business analytics service Mixpanel, about 13.3% of iPhone users have upgraded to iOS 16 since it was rolled out on Sept. 12. That's when reports of battery issues started popping up.
