Up to 50% performance drop on iphones after the spectre security patch
@troubleMoney just FYI that upgrade was also the one that was involved with the "battery degradation reducing performance to maintain battery power duration" thing.
@fabianhjr @troubleMoney That was 10.2.1, not 11.2.x, that did that...
It was both. 10.1 -> 10.2 and 11.1 -> 11.2
@troubleMoney wow geez
