iOS 10.2.1 Latest News & Update: Current Mobile OS Roll-Out Offers Broad Coverage Fix By Joseph Patrick | Feb 26, 2017 07:49 AM EST For iPhone owners, most may have already gotten prompts of iOS 10.2.1 ready for download. The latest update from Apple is believed to be something to address the celebrated 30-percent battery bug plaguing the iPhone 6 and 6s. But how about the other iPhone models? In an interview with Tech Crunch, Apple claims that it intends to reduce the unexpected shutdowns by 70 to 80 percent for the iPhone 6 and 6s devices. Taking it abruptly, these were the models who had suffered from the battery bug. The problem was previously blamed on the series of iPhone 6/6s models that came out so it comes a bit of a surprise why iOS 10.2.1 would be specially suited and not covering other models – iPhone 7 included. The rollout of iOS 10.2.1 hardly seems like a full-proof solution given those facts. But the reality of it all is that the latest Apple OS does bring other problems too. That includes a bug that lower screen brightness, Touch ID issues, Bluetooth connectivity problems and continued battery drains, Forbes reported. Given those problems, the only handy thing that iOS 10.2.1 may have are the usual security fixes – meaning users will still be forced to update to it. With Apple saying that about 70 to 80 percent of the iPhone battery drain problem likely to be resolved, it may be the bright spot for the current iOS 10.2.1. Some users have noticed improvements, claiming unexpected shutdowns for the iPhone 6 and 6s models. But as stated earlier, what about the other models? Apple continues to offer battery replacements but only to select models according to the Apple Support Forums. For those who plan go this route, it would be best to consult with a certified Apple service center to see if you are entitled for a battery replacement. Only select models are accommodated so it could save affected folks some time.
