iPhone 7 lagging when unlocking

Wondering if any iPhone 7 users have experienced this issue whereby the phone will lag and become very sluggish when unlocking the phone. This issue arrived when I updated to iOS 14 and I didn’t have this problem in iOS 13. After unlocking , the animations will turn off and opening apps, scrolling through your apps will be really really laggy. After about 10 second when the unlock icon at the top of the screen disappears, then everything run as usual. Please respond if anyone have faced this issue before.

If you do not go into the details of that setting and how to install it, then I made a twice of conclusions and tests:


1. When unlocking, the SpringBoard system process is loaded up to 70%-80%, which is why the iPhone starts to trottling, or rather its CPU.

2. Perhaps the problem arises due to the fact that the iPhone goes into a “deep sleep” when locked and from this problem

3. The problem was really solved by the LastLook setup installation, but today once a day I had a bug with the unlock animation and everything became normal

I have been experiencing this problem since ios13, but the problem has worsened after updating to ios14. It used to happen very rarely on ios13 and I thought if I upgrade to ios14, the issue would disappear....

My device has never experienced shut down because of low battery health and the unused storage is almost 45gbs, therefore these factors DO NOT cause the above issue.


Really unfortunate that Apple is ignoring this and literally bullying us into buying new iPhones.


Can anybody test and confirm if this problem is solved in ios14.5 betas or if the frequency of it occurring has been reduced?

Thanks!

Here is the solution step by step guys:

1: JB your iphone

2: setup LastLook tweak 

3: problems will be gone


I think the problem occurs in A1778 models. Source of the problem is the bugs when phone trying to go into deep sleep mode. But this problem occurs when phone immediately try to go into deep sleep mode after lock your iphone. Thats why when you open click sound at the lock, there is no problem for 10 seconds. Or when you are charging there is no problem. Or when you open flashlight there is no problem.What we do with this tweak is; preventing the phone to go into deep sleep mode why we locking it. Instead of go into deep sleep mode while locking, phone is waiting 5-6 seconds to go into deep sleep mode with this tweak.Problem is %100 solved. I found and using this solution for 2 week. There is no problem after all. Also there arent any problem with performance, battery etc.


I tried to explain to you simply. I used many programs to find this log. I cant explain more because this JB thing has made this comment been removed :) I hope you can manage it.


So dear apple care family, this is a %100 software problem. We expect to find a correct fix at the next ios updates. I can work for you because I’m an software engineer. Waiting for your proposes. Stay healthy.

Just one more confirmation to this annoying and shameless bug.

I have a 7 Plus 256Gb model, a lot of gigs are, battery level is 82%, current IOS version is 14.4

The bug started to be observable after I did upgrade to IOS 14 version.

I tried to reinstall IOS, doesn't help.

It's feels like using a cheap android phone, quite often I just want to break it at all.

Shame to you Apple!!!


By the way the bug is not observable on iPhone 7.

Lol so my previous post got deleted but to be honest, I feel like it’s fixed, but I’m not gonna celebrate to soon because I have been facing this issue for a long time but the new version of the software (I can’t say the name because then it’s gonna be removed again) feels so smooth. But I’m not to sure yet so I’ll just continue using it to make sure.

iPhone 7 is the worst iPhone ever. My friend has ZERO complains with his iPhone 6s. Even my father’s iPhone 6 runs smooth. Why the heًll did I spend more money and get this shْit?! First the issue was missing unlock animation on iOS 12 and 13, Now? Unlocking my phone? LAGGING. Scrolling over home pages? LAGGING. Enabling airplane mode for while and turn it off back? Status bar glitchs and keeps showing “plane” icon instead of signals indicator ! Trying to swipe up to open control center when you have many apps opened in the background? It won’t respond and you have to swipe up slowly to open CC. And there is more of bugs and issues, in fact, every single update introduces new BUG ! What is this shiًt I’ve put my self in!

Please Apple software engineers do your fucًking job and fix these issues.

I just fix mine problem with lagging, its simple really 😁 I can't believe I didn't do it earlier. What you need to do is step 1: go to xiaomi store, step 2: buy xiaomi mi 10T pro, step 3: sell iphone, Apple watch, step 4: cancel all apple subscriptions. Problem solved! Now I have very fast phone, 144hz display and everything is so fluid and going smoothly. Great cameras and not to mentioning battery life of 9-10h screen on time and 11-12h standby minimum. Apple bye bye cos you disappointed me for the second time and now there is no returning back. Guys see yaaa and I hope they fix problem for you all or you just do what I have done and have great phone, great cameras and battery life.

It’s currently on in my device and it’s still there. You will experience it it’s a matter of time.

After any update installation, stuttering looks like it goes away but you will find it still there. That’s because ios after updates works in background for optimization, that prevents deep sleep function thus you wil not have stutter TEMPORARILY.

I faced the same problem. The first time my iPhone 7 started to lagging

after unlocking when I installed ios 14.0. Not immediately noticed, so I did not have time to roll back to stable 13.7, in which this problem was not observed. I have been trying to solve this issue for a long time, but I have not been able to find any solutions. Sorry for my English. Written with google translate
