Battery life on my iPhone 6s is getting really bad to a point where it's difficult to go through a full day with only moderate usage, so I was wondering if anyone here has had a recent battery ...

Apple says it will replace the batteries on some models of the iPhone 6S that could unexpectedly shut down, but pose no safety risk.

Apple recently launched a battery replacement program for iPhone 6s owners with faulty phones and it seems iPhone 6 owners could soon get the same deal.

Here, you can see your iPhone battery’s “Maximum Capacity,” which is a measurement of how much charge the battery can hold compared to when it was new.
