Aside from contacting Apple to get a (hopefully free) battery replacement, the only other thing to do is something along the lines of what's being discussed at Apple Being Sued for 'Purposefully Slowing Down Older iPhone Models'
That score looks like it's in the full speed margin. The scores vary slightly each time.
The way you typically get apps--via the App Store:
Check your phone's battery health with Coconut Battery. If it's below 80%, Apple will replace your battery if under warranty.
Seems fairly unusual to have so many cycles in just a year.
Still quite a bit nonetheless which can certainly play into the overall health of the battery (even if the capacity part of it might not be as heavily hit).View attachment 743337
I bought it the day it came out (16th of September 2016) so it's actually only 1,57 full cycles a day
Well, it shouldn't really be insanely slow unless perhaps the battery is truly in bad shape and/or something is up with the power management changes that were put in for it all. That aside, it seems that it's not so much about shorter battery life but unstable battery life that can cause the device to just suddenly unexpectedly to shut off (perhaps in the middle of you doing something or while you have your phone somewhere thinking it's on and everything is fine while it has shut off without you even realizing it). Not a good outcome either way if those kinds of things would be happening. Seems like the solution, or at least a workaround, would be to get the battery replaced.
