iPhone slower after iOS 10.3.3 installed

Good afternoon. So i had my battery replaced for my iphone 6s plus. Suddenly it became so slow especially when opening apps and using the 3d touch, it bugs and lags almost every time. When i charge my phone, it becomes fast again. Charging my iphone is the only way to solve the bug but when unplugged again, still lags. I Restored my phone and nothing helped. Any thoughts about this? What should I do? My iphone is on ios 10.3.3

Hello,

I bought iPhone 6 from Flipkart site, however, there is a lag when I scroll down in the menu and other things. Will restoring the iPhone via iTunes will solve the problem for sure?? I thought iPhone was known for his speedy performance but mine is not up to expectation. What should I do, please help

So has mine. It's the new iOS file system I think. When I power cycle off then on, it literally takes forever for my 7 Plus to come back on. I was on 10.2 and there's a HUGE difference in speed! Thanks Apple!

If it's the new iOS file system then over a half billion phones would have the problem, including mine. And I've seen no indication that it is slower on my 7 Plus, and very few posts reporting a speed problem. The new file system is designed to make it faster, not slower, so you most likely have some other problem. You should try the troubleshooting step posted as the first reply to this thread.

One thing that will slow down iOS is if you are in the habit of force-closing apps by double-pressing the HOME button and swiping them up. I hope you are not doing that.

Absolutely. I currently have around 120 apps that show when I double-press the HOME button. But I also have some authority figures on the subject:

But the highest authority:

Apple’s software SVP says quitting multitasking apps not necessary, won’t offer improved battery life or speed

Our organization has over 480 Iphones in use; all of them were updated after the last update was available. The performance has suffered on all the phones. Freezing, laggy, text & talk to text is next to unusable now, and the screen often either freezes or bounces around making it difficult to pinpoint what you want. These were all the common complaints.

To make matters worse. My gf who has the same phone and purchased at the same time, didn't install the update, and her phone is miraculously fine.

Very shady practices from apple. Suffice to say, our company is dumping Apple products after this one. Come spring when it's time to renew the phones, it won't be Apple

Go to https://apple.com/itunes and get it. iTunes is free.

are u sure.... of that closing all apps....???suddenly after using fone slows the phone??? bcoz i do that...but whats the problem if we close all the apps immedietly

ok thank you so much, u were really helpful...:))

What if I don’t have iTunes?

My iPhone now runs very much slower after the recent update , which was me at to make it faster.

I agree! Overnight my 6s became noticeably slower. There is a lag in most things I do. Very frustrating!
