Delay when iPhone 4s wakes up ...

[ANDYMILLMAN]

Not a major issue and I don't know whether it's iOS related but give this a try ...

Lock your phone so the screen goes off.
Leave it for about 30 seconds and hit either of the home
Or on off switch. See if you get about a 2 second delay before the screen turns on.

If u then hit the screen off and on again it will come off and on almost instaneously. It always seems to happen on the initial wake up after it has been idle for some time

This exactly describes my 4S. I have tried restoring the phone, it didn't help. Side by side, if I press the 4 and the 4S's lock buttons, the 4 is significantly faster.

My 4S wakes virtually instantly.

This occurs on my iPhone 4S too after the screen has been off for a while. It's more than likely related to power saving functionality. I don't think it's something to worry about.

Hmm I thought this was my imagination but I guess not. Hope apple fixes this in 5.0.1

Same here with my 4S. Hopefully it'll be addressed in a future software update. My iPad 1 does the same slight delay after being updated to iOS 5, but my previous iPhone 4 awakes instantaneously when you press the home button.

D'oh, now I can't stop noticing it!

Oh, I should mention that the 4 is still running 4.3.5.

same with my 4s, and i compare 4s with my 4, both are running ios5, for the initial wake-up,sometimes 4s faster, sometimes 4s slower sometimes, they are even. damn weird, it's not a problem, but pretty annoying

I noticed this too and it happens on my girlfriends iPhone 4 running 5.0 as well. I think it is just some sort of power saving feature, not that it bothers me that much though.

 

[cababah]

I have that as well. Also, whenever I restart it will always be "Searching..." for quite a while before it locks on a signal. This happens in areas of low service and good service.

Not seeing this delay at all on my 4S w/ 5.0.1.

 

[Jman13]

It's there for me too, but it's nowhere near 2 seconds. It's a half second at most, and frankly I have never thought anything of it. I'm sure it's a result of a power saving state.

 

[film major]

I noticed this on my I 4S as well. Doesn't really bother me, it is no where near 2 seconds. But, it doesn't wake up instantly.

Same thing for me too, less than a second for sure.

My iPhone 3GS running iOS 5 actually wakes quicker than my iPhone 4S!

 

[Jordan921]

Not having wakeup issues with my 4S

Delay As Well

I did a side by side comparison of my 4S with my coworkers 4. Everything about the 4S was slightly faster, loading apps, closing apps, opening settings, switching multitask, starting camera. Even showing lock screen immediately after locking phone was faster.

The only thing the 4 beat the 4S on was waking from Sleep Mode. My 4S and my dad's 4S both have a 1.5-2 second delay to show the lock screen after the phones gone to sleep mode. The iPhone 4, had almost no delay. This annoys me a lot, but its really not a big deal, hopefully Apple will address this in a future update. It seems to be an issue with either iOS 5 or the 4S itself.

No solution yet

Things I've tried:
Reboot
Factory Reset
Disable Siri
Disable Wifi
Disable Cell Network
Disable Location Services
Turn on Airplane Mode
Use Process Killer App

I've noticed it as well, but it doesn't bother me that much. Like others have said, it's probably due to the battery-saving feature, wonder why this wasn't the case in the iPhone 4 though.

 

[CubeHacker]

Strange, my 4S wakes up instantly. Same with my 4.

 

[Mr.C]

My 4S wakes virtually instantly.

So does mine.

Same here.

 

[peto01]

i have this delay too, but when the iPhone is charging, there is no delay.

 

[saving107]

I have the delay on my iPhone 4, or had because I don't notice it anymore with iOS 5.0.1
