iPhone 5 power button lagging on iOS 6.1

yes, it's happening to me on my iphone 5 too.

i upgraded via itunes on mac, not OTA

Same problem with my iPhone 5. Updated via WLAN without iTunes.

And I was thinking my lock button's messed up

thanks guys will be updating to the new os

I have had this problem for a few weeks now and i have also updated my IOS to 6.1 and its still the same, maybe even worse. If you click the button on the left hand side it will work but if you click it on the right hand side it doesnt responed. Back to Apple shop for me.

i am also experiencing this problem - it started as soon as i upgraded my iphone 5 32-gig through itunes.

VERY annoying.

i got fed up with my intermittent lock button problem (it seems to work better if i press slightly to the left) and took my iphone 5 into the apple store. they replaced it without any fuss. apparently it is a known hardware problem, but for some reason it becomes more apparent after upgrading to 6.1.

hope you guys manage to sort yours out.

do you know if there's any official/public bug report?

Same problem with my iPhone 5 (gsm+cdma)

Updated via OTA.

Any other?

@Martin: Is it GSM+CDMA?

May be someone who saved SHSH blobs could downgrade iOS to 6.0.2 and try if this problem continue

😟

I have been having the same problem since the update. Updated OTA, GSM.

Just last night randomly started happening to me as well. I've been on iOS 6.1 since the public release. I haven't dropped my phone or anything to make the power button behave different. I'm taking it to the Apple Store today to hopefully get it exchanged for a new one.
