iPhone 7 lagging when unlocking

У меня такая же проблема, я отдавал телефон в сервисный центр, мне заменили по гарантии таптик энжайн. Через сутки, после того как мне его отдали проблема вернулась. Мне помогает отключение тач айди, но это не вариант вообще. У меня эта проблема была и на iOS 13. Я сдался и выложил телефон на продажу.

I have the exact same problem, but not just on a 6s or 7. it does happen on my iPhone 8 as well. When it happens I see 100% cpu usage and after some

time it stops lagging.

When I use the same backup on an iPhone X or newer, there are never any lags after unlocking the phone.

it must be a bug in ios 14 with touch ID, cause I never had such lags on older ios versions.

Please Apple fix this problem. It‘s still there in 14.4. and it is very annoying

Well you don’t really do that action much on a regular basis in normal use. I tried replicating what you said and it does lag; but the lag that occurs in normal unlock, which we regularly do, seems to be resolved if not lessened by this method.

ı have already tried pro flash on 3u tools in DFU mode. There was no problem until evening. After hours laggings were come back. I think this problem occurs in iphone 7 (GSM) models. Which is A1778 iphone9,3. And source of the problem is other storage. When you use the phone and when your other storage increases, laggings will begin to show up.

Update: after dfu mode, lag is still there, this didn't help either, I tried everything and what I noticed that in past few days lag is start to be even worst and longer, and even start to lagging when I use the phone like working normally and then start lagging on switching between apps or keyboard lagging etc. and not just on unlocking the phone...

I never change anything except oem battery, that was last year and its working fine until ios14 update. Battery is okay and health is good. Screen and everything is original from this phone so hardware is not an issue, its ios14 bug and its not fixed yet. I tried all solutions and none of them worked so far.

Oh yes, I noticed that too with music, if I'm listening in apple music its lagging way more even when I use phone in other apps like viber, instagram etc. and its like 2 frames per second sometimes when I unlock the phone and using it for 5 sec, and when I shut off apple music app lag in most cases disappear...

I have the same problem with my phone too.

I have iphone 7plus 128gb. I have used only 14GB/128gb and in-spite of so much available space the phone lags.

This issue started after I updated my device to iOS 14.4. I did not face any issue when i was using iOS 13

Kindly fix this issue at the earliest and do not make me regret for shifting from android to ios.

When unlocking two phones and Background 7 slows down, when you need to quickly open the camera, you need to wait about 10 seconds until these lags pass, it starts to get really annoying. No dfu modes, turning off auto brightness and other methods suggested here do not help! Apple, solve this problem! And stop deleting the post from this thread.

I also had this problem on iOS 13, back in April 2020 support said that it would fix it in the next update))) Last week I contacted support again and they said again that they would fix the problem in the next update. I installed ios 14.5 beta and the problem persists. They will not solve it, there is only one way out, sell the phone and buy another.

To solve the issue dont use home button use rest finger to open feature for unlocking without pressing home button and use assistive touch for closing app dont press home button this issue due to pressing of home button

I try that too and that doesn't help either. When I unlock, with or without raise to wake, and using rest figner to open and unlock phone. When just raise to wake or if its off and pressing home or power button to wake the phone, back light is so dimmed and its like step by step going from dimmest to brightest, its like dimmest, after half a second its on half brightness and other second is at full brightness. Its sooooo lagging even with backlight turning on, and press or rest finger to unlock then there is no animation and smoothness when unlock, ist just so slow that miss some animations and go straight to home screen, and after 2-3 sec it came to life and work just fine after that, sometimes when switching from app to app it lags. And when it works fine, just lock it and unlock it and again it lags and everything With back light keybpard for 3-5 second, rarely lags goes over 5 sec, and again after that it works fine... sometimes when I type no mater what app is, keyboard just freezes for 1-2 sec and when unfreeze it types everything I type when it was frozen... its so many bugs in this ios then I ever before and its frustrating... I have old android from 2010 and it works better with way less lag than this ios 14,4. What Im noticing 14.1 then 14.2, 14,3 14,4, with every newer update this bugs going from bad to worse, and being more and more laggy and worst with every new update.

Its every day worse and worse, and so disturbing, annoying, frustrating to use it... From loving this phone, size, diaplay, one hand use and being okay with so terrible battery life of 3-4h screen on time, and loving to keep it and probably buying new SE or 12 mini, now im starting hating this phone so much that it's start to going on my nerves and I'm not even going to sell it, just throw phone, apple watch, ipod in bin, and not saying about paying music and rest to apple that need to cancel now. I'm now looking for Android phone back again (after 3+ years) same size or similar as this 7. Iphone you disappoint me over again, I gave apple another chance (cos first time was the same with lagging and freezing 7-8 years ago) and now it was great, so smooth to use that I love it so much, until ios14 and now its nightmare, freezing lagging like im usin 2G from 2007, and I start to hate this phone a lot and can't wait to find phone (android again) that is good for me again.

I can’t understand why Apple is ignoring this issue. Even if it is an older device but still many people are using it.

every one is facing this issue and not only 20-30 people litrally every iPhone 7 user !

What's so **** frustrating is my gf old iPhone 6s and my friend iPhone 6 works better than my newer iPhone 7 with this stupid stupid issue. I have been in Apple "ecosystem" for a long time but this kinda proves Apple is no longer a company they're used to be. IOS was a major bug-free OS but however with recent releases and sloppiness like this, Android is going take that place it seems.
