Oh if true this is nastiness …..
So, Poole used Geekbench’s benchmarking testing to find out. He conducted single-core tests on iPhone 6s and iPhone 7 units running different versions of iOS. His findings suggest that Apple has made a tweak in iOS 10.2.1 to 11.2.0 that appears to throttle the iPhone’s performance when the smartphone’s “battery condition decreases past a certain point,” Poole said.
The change was likely made after iPhone 6s users reported that their smartphones would spontaneously shut down even when there was seemingly more than enough life left on their batteries. Apple acknowledged the shutdown problem and offered a battery replacement program. The company also released an update to address it.
I’ll tell you what’s going on here with the batteries.
As lithium batteries age they are unable to sink as much current as they used to be able to — either charging or discharging. At a certain point this becomes noticeable; you seem to have plenty of power, you turn on the GPS in the phone (which has a high drain) and whammo — the phone shuts down.
