I used to think that was a joke, but since updating to ios 11 my 6s+ has been completely unusable. A bunch of the apps are now unresponsive for 5-10 seconds after they launch, the input lags and the standard ios animations are dropping a ton of frames. Battery is also sometimes draining 20-40% in a span of 15 minutes.
I have a 6s plus and had the exact same thing. Phone was totally unusable. But I did a full backup and reinstall and it’s gone back to normal speed. Feels like a new phone. Give it a try.
My 6 Plus turned to absolute sluggish crap after iOS 11. Will try the reinstall this week. Suspected that might be worth a try, but had been hoping the first two 0.x updates might've solved it first... no luck!
A common approach on Android. Nobody really seems to know exactly why, but evidently crap accumulates, either from old apps or from sloppy in-place OS upgrades. A full reset clears all the crap, and you start anew.
I prefer to skip even the backup step, instead relying on cloud sync for contacts etc, and manually dumping a couple apps.
Yes -- give it a try. My iPhone 7 Plus was nearly out of storage space, and also rather sluggish. Much of the storage space was being consumed by internal Apple files according to usage details within the Settings app.
After doing a full backup using iTunes, then resetting the phone to factory conditions, and finally restoring the iTunes backup -- my storage space returned to normal, and the speed increased dramatically.
I suspect that over time, internal files accumulate (e.g. log files & upgrade restoration points), and this accumulated cruft gradually consumes space & degrades performance.
Yeah it made it soooo much quicker. I was about to throw it in the bin. Now set for another year of retro phone. Mine was being really shitty though, it took a massive speed nose dive after ios11. If that’s what happened to you defo worth trying.
I thought I was just unlucky because nobody else shared the same experience as I have had, but you describe exactly the same behavior I've encountered since iOS11
Solely from a performance analysis standpoint, you've just perfectly described something using 100% CPU across all cores.
But you aren't reporting the phone being warm to the touch, so... hm.
Have you tried wiping and restoring it?
It could be interesting to back it up, wipe it (and maybe remove the SIM card for completeness?), install the worst performing apps on the fresh install, and _then_ (maybe wipe again(?), then) restore it back to normal.
If app performance is terrible in the fully-wiped state, I'd take the phone into an apple store (regardless of warranty status) just to see what they say.
Hmm. Just thought of this: maybe your battery is like the OP's from reddit but in really bad condition, and your phone is downclocking itself to compensate?
My iPhone 6s Plus gets extremely hot, battery life sucks, camera doesn’t focus, and apps are not responsive. Whenever I’ve brought it to an Apple store they said there are no issues...
basically there are times when it will drop sigbnificantly in a short period, but i have also had it last significantly at 1% and go from ten to 1 in a second - then i rush to plug it in and as soon as I plug in the cablee it immediately jumps back to ~15%
Do you charge it with a stand or fast charger? Anything with more amps than the original plug? If I do that it really screws up the phone and it loses charge really quick. A few days of old fashioned charging and it’s ok again. Same thing screwed up my wife’s iPhone battery
Not remotely true. The iPhone is designed to gracefully accept charging from, for instance, Apple's iPad chargers, which provide either 2x or 2.4x the power of the bundled iPhone charger. There is no evidence that this degrades the battery.
Now, if you use crappy 50-cent third-party chargers, I don't know what happens.
You say it’s not the but it is my exact experience of them. Happens every time. Tried it a few times to be sure it’s that. Using a Belkin dock and an Anker charger. Both decent enough brands.
It's up to the phone how many amps to draw from the charger. Just because the charger has a higher amp rating doesn't mean that the phone is drawing more current from it.
Voltage is applied, current is drawn. It’s basic physics. You’ll fry a phone by connecting a charger that operates at a higher voltage level, but it’s perfectly harmless use a charger with a higher amperage rating
iOS 11 was the same way on my 6s+. Then I swapped the device for a new one. It doesn’t feel nearly as sluggish. My battery works like it did on iOS 10. My old device had a battery that was barely in the acceptable range. Obviously, my experience is anecdotal.
I'm light on battery though. No movies, no books, a wee of games, some browsing. Heaviest use is sports tracker and maps. I do use it for testing apps nearly daily. But usually it's hooked up to Xcode.
Do you use Google Voice? The latest updates are horribly unresponsive. I think they are sending data to Google with each key typed and all on the main thread.
