Sounds as though it might be time to get the battery checked out and possibly replaced.
My 5s started running slower and doing random shut-downs, even with a full charge. It began doing these after the iOS 10 update, but since I'd had the phone for for 3 years by then, and it's my only phone for the past 2 years, I figured it was time to get clarity on why this was happening, as it was only getting worse with each update. It was driving me bonkers when traveling and needed Google Maps to guide me (btw, I'm still using iOS 10.3.3) and other apps to help find flight info, restaurants, etc.. I finally took my iPhone to my local Apple store in June of this year.
The tech I saw ran a diagnostic on my phone. One of the diagnostics showed how many charging cycles I'd done and that I only had 63% of battery usefulness/capacity left, even when fully charged... something I couldn't see myself to know that was the problem. The tech said I could either buy a new iPhone (I'm still considering buying an SE for several reasons, but haven't the cash right now) or replace the battery. The battery replacement would be $79 + sales tax and the Apple store could do it right then and there. I decided to investigate it a bit at home and learned an indy shop would likely charge about half what Apple does. So, I called 4 indy repair shops. The shop I went with charged me $32 + sales tax. The most expensive indy shop wanted $48 + sales tax. I could have bought all the necessary parts on Ebay and done it myself, but I was too worried of causing damage to my phone, because my eyesight isn't that great anymore. So, for the extra $10 or $20 dollars I paid, I figured it was worth sitting in the indy shop's waiting room for an hour (I actually went for a walk instead since it was gorgeous day) and letting someone more skilled than I do it for me. SO worth it! Having a new battery totally solved the slowness and random shut-down issues I was experiencing.
I haven't updated to iOS 11.x because I haven't got enough room in my iCloud storage account, and I can't afford to be without a phone, in case I run into any problems.
I also run a VPN on my phone to prevent snooping, etc. too. Yes, it eats up battery charge when it's running, but replacing the battery is much cheaper than buying a new phone.
https://www.macworld.co.uk/how-to/iosapps/how-downgrade-from-ios-11-beta-go-back -ios-10-3522302/ I found this article, but I was not able to successfully downgrade. I couldn't get past the part just before plugging in my iphone to computer. sigh.
I thought it was just me but I see that I am not the only one suffering from this garbage update by Apple. My iPhone 6s was running a lot smoother before this latest update and now it's even worse than the initial iOS 11 update. Apple, WHEN ARE YOU GOING TO FIX THIS?! EVERY app is sluggish and there is a delay with response times to opening ANY app and clicking ANYTHING!!!
Yes.. latest update killed my iphon 6 interna of performance. Th most annoying thing my the time you open camera to capture a moment, it’s gone.. rediculous..
Is there way to ggo back to previous version
It’s simply time to just boycott Apple. We’re beating a dead horse at this point. The company died with Steve Jobs- everyone knows that. Apple just wants to make more money by forcing consumers to buy their “new” and “shiny” improvements, including their faulty updates which slow your phone down either way. The person/team who decided to take out the ear jack will unfortunately suffer the consequences. They don’t know our generation AT ALL. Just don’t update your phone, or go back to the flip phone.
So i've just done the 11.1 update thinking, hallelujah, at last Apple have released the fix for breaking our iphones by making them slow and a nightmare to use. Erm.....
IT'S FIXED NOTHING!!
My iPhone 6 is still laggy, slow, and the volume button doesn't work properly (phone rings as if on 70% volume even when put down to 5%).
Oh, but they have given us new emojjis in the update....way to go with you fuc*ing priorities Apple! (***??)
I am 100% never buying another iPhone after this. I'm sick of Apples disregard for us customers.
It's terrible, my camera won't load in time to take a picture of anything faster than a drunk snail.
My fiancee's father and my father both tried to load their cameras to get an engagement toast, they failed and bonded over how bad iOs 11.0.3 is.
Really bad bad job Apple.
This is an apple support forum moderated on an Apple website - WHY THE H3LL ISN'T APPLE REPLYING HERE WITH ANY SUPPORT?????????? Why aren't they giving an option of downloading the ios 10 so we can downgrade to an ios that works?
Unfortunately I recently bought 7 plus, so cannot escape. 6S touch response is slow or flickering, anyway it’s no more Steve Jobs company. I think Apple is ready to compromise on many grounds, however they shouldn’t take a risk or play around with Apple customer base.
Mine too. IOS11 on my 6+ is basically unusable. it takes 7-10 seconds to open an app, SIRI is completely useless. the worst thing I ever did was install IOS11.
What is going on Apple? you destroyed my 6+
Reset does not fix it. It is completely irresponsible and negligent of Apple to release such an unstable ios and not offer a downgrade back to 10 as an option. We have been used as guinea pigs. Why should any customer suffer while they try to get their $h!t together. I don't care how good anyone thinks it will be. I just need the basics to work - touch screen, apps to load in less than 2 minutes... camera to not need 30 seconds between shots, and the network unavailable thing - I never in over 5 years of being an Apple user had that, even when out in the sticks of west texas where there is barely a cell signal. It is total BS.
IOS 11 also killed my iPhone 6S 64GB. Random hangs and freezes, apps locking up / exiting, Caller ID doesn't get sent randomly. I guess this is how Apple wants their customers to buy their new phones.
I totally agree W Ur point of view, for example Today I’ll sell my Iphone 6 plus 64 GB to buy a Iphone 7 32 but I don’t really know if Apple Run a new Ios N then My phone run Slowly If that Happens I’m Avoiding using Iphone N buying a samsung ... furthermore ... I used to buy somemany Apps that in Samsung are For Free...
Same here, after upgrading my iphone its really slow, typing its really annoying because its takes seconds to respond.
App are running slower and sometimes stop running, unlocking the phone sometime does not work properly either.
Apple please help. I think this is ridiculous what you are doing to your customer. 😟
Ditto - it is driving me crazy! The time it takes to recognise the call i have just made and add it to the top of the recent list means i keep phoning the wrong person. it is taking 3-5 seconds to register, opening apps is slow, texting is slow, opening the camera is slow... I have the 128gb with over half of it free so it is defo not a storage issue. I love my 6s... I don't like the newer versions... I have seriously been looking the the new Google Pixel... None of the update are addressing the issues with the older models and my older I mean I have had this one less than 18 months.. I am not going to buy a new iphone because Apple think they can force me to. I will go Google.
Iphone 6S is a couple years old. By design, Apple wants you to buy a new phone. So about every 2 years from a purchase you can be certain that an update will "break" your phone as one user stated. I also have the 6S and the degradation in performance is blatant across multiple apps. I'm no longer shocked. Apple, you're no longer fooling me. Personal Computers don't go through this crap. Why must phones? Quick and consistent money, that's why.
my iphone 6s is running very slow after ios 11.0.3
