iPhone 6(S)/Plus iPhone 6s wake up lag

[Tommy-Li]

Hi everyone, recently I found my iphone 6s lagging when I try to wake it up. All the wake up methods would cause it to lag, including raise to wake, lock button, home button. Even the silent/un-silient switch would lag. It does not happen every time, but it's quite annoying. Does anyone know why is this happening?

Thanks a lot.

Why what is happening? What do you mean by “lag”? Can you post a video?

I have a 6S (Samsung chip if that matters). Some possible causes of lag:
- iOS is in the middle of updating apps in the background
- the phone is in poor data/cellular/wifi connectivity
- it just happens

I would try rebooting the phone, charge it, move it to better data connectivity (or put it in airplane mode).

Hi,

Thanks for your reply. Essentially what is happening is that sometimes when I try to wake up my phone, the screen would not turn on until about 5 seconds later or longer. During that 5 seconds, all the buttons would not work. But when the phone is unlocked all the buttons works fine.

DFU restore. If still not okay then start afresh.

Thanks for the description. I think it's more meaningful, because I wasn't trying to be snarky. I really have never seen anything like that. So you touch the home button to wake the phone and nothing responds for about 5 seconds. I can't think of what that could be. Is there any chance your battery health is going bad?

Hi everyone, here's a quick update on this topic. First I want to thank everyone for your help! I have tried all the methods that you guys gave me, like replacing the battery and DFU restore etc. But the problem remained and got worse. Now it takes at least 20 seconds to wake up
