Question: iPhone running half speed
my iPhone 6 Plus, which I recently ”upgraded” to iOS 11.1.1 is running slow. I don’t know if it started running slow immediately after upgrading or some time after. If after, it didn’t take long to reveal itself. Geekbench 3 gives me speed results pretty emuch xactly half what it lists what it should be, and half what it was previously. It’s uncanny how the results are pretty much exactly half what they should be, both for single and multi core scores. I restored the phone to factory (via iTunes) and set it up from a backup, but it made no difference. I hesitate to set it up as a new phone because it’s such a hassle, particularly since iTunes no longer does apps. Does anyone have any idea what could be causing it to run half speed? Or how to figure out what to do to troubleshoot and fix it?
