Performance seems to be on par with iOS 7 on iPhone 5. However, battery life is all over the place, sometimes it's amazing while I'm using it(1% every tenish minutes on safari), but leave it in my pocket for an hour and half and it loses 5%. Does anyone have any fixes? I restored as new and reset all settings. Location services all the way off and background refresh for only four apps.
 
iOS 8.0 has an in-built monitor where you can see which app consumes how much battery % ( history view ). It should be easy to identify the leaks.

I am noticing slow wifi performance with safari. Especially when loading Macrumors. I see the blue status bar starting to move slowly before it completes. Takes around 4-5 seconds for the blue bar to complete. Anyone else seeing similar performance?

I noticed that a bit last night after upgrading to iOS 8. I did a hard reset and have not noticed it again since. I don't know if the reset really did anything though. :D
 
if it's especially a specific forum it's most likely not the WIFI, it's the forum which appears to be slow ;)
 
I've closed all apps and restarted my phone yet the battery is going down fast! I've been mainly in standby mode all day. Any thoughts?
 
my battery appeared to drain very fast as well. it was going down 5% every 10 minutes. i thought i'd try and drain it down to 0% and do a full charge, so i upped the brightness and started playing videos, but then it stalled at 26% for ages. so overall i think i probably got the same charge, it's just that the reporting was all messed up. after i did a full charge it seemed to go back to normal
 
There is a the slightest bit more lag, and very occasional jerkiness but works very well for a 2nd iOS update. Battery life sucks though!

Exactly this. Lost 50% battery in 2 hours with minimal use. This is with no background refresh and plenty of other stuff disabled.
 
My biggest issue right now w/ my 5 is the jumpiness. I feel like there's jumpiness or jerkiness when I send a text. My text is larger than average but that never happened before.
 
Really my iPod Touch 5, with 512MB ram and an A5 processor, after updating yesterday, then opening and closing everything at least once and scrolling up and down through everything to let all the little caches repopulate, letting the battery run down a bit and then recharging, and then rebooting twice, and finally just leaving it alone with wifi on so all it's iCloud resyncing stuff could finish, runs exactly the same as it did before. If this had been called iOS 7.2 there probably would be like zero complaints. But then the iPhone 4 support couldn't have been dropped without outcry, right?
 
My battery life has been terrible today.

Got about 11 hours on standby and just over 4 hours of usage with about 22% battery life left. This has all been on Wi-FI too, not mobile data.
 
As of right now, iPhone 5 A1428 with serial number ending in FH19 and T-Mobile US Carrier Update 17.1 running iOS 8 build 12A365 does not support Wi-Fi calling.

Otherwise, it's fine for me.
 
Working okay for me. Just a touch laggy, but nothing bad, some apps seem to get stuck in landscape, and Swype makes things crash randomly.

It's workable.
 
Im on iPhone 5. Its just about the same as ios7. I really only noticed lag when swiping down on notification center on the lock screen. Control center is fine.

Whats funny is in ios7 control center was laggy in the lock screen and not NC. They have switched places :rolleyes:
 
Ok. I'm just trying to determine why there would be a slow down in scrolling. I doubt the code changed much. There are hundreds of factors affecting a phones performance, one of which could be a poorly designed app your using which is using up processing power in the background. Scrolling is as butter smooth on my iPhone 5 as it was on iOS7. So I wonder whether this is a rather isolated problem affecting a fraction of iPhones or a broader problem.

Good point, but not really feeling to install one app at the time.
And loads of apps don't use iCloud yet, so I prefer having to put a backup back. Or I will loose settings and data...
 
horrible

My 5 is horrible, delays everywhere. Scrolling through photos (years view) at about 3 fps... trying to downgrade now. First iOS i'll be skipping!

True, clean installs are becoming more painful every year.
 
iOS 8 on iPhone 5?

I updated my iPhone 5 OTA from 7.1.2 to 8.0 last night. Been stable for me.

There was some noticeable lag immediately after rebooting, but the lag disappeared this morning. 8 is indistinguishable from 7 in terms of scrolling and general interaction. WiFi does seem to have some extra latency.

Battery life got better. Hope it holds up.
 
FB Crash

Installed 8 yesterday Facebook crashed out twice and much starting YouTube videos, seems OK once the video starts. Otherwise good.
 
iOS 8 is running great on my iPhone 5, with the exception of Safari. On some of the heavier mobile sites, I'm experiencing lag when I try to scroll on occasion.

Still, the update was more than worth it, for the keyboards alone.

Crippling one of the main features was worth it because you got to play with some different keyboards? Uh, ok.

Most websites still work fine... it's not the end of the world, especially because everything else is just as smooth for me as it was on 7.1.2. I know better than to expect flawless performance on a two year old device.

Some sites not being as smooth as they can be when scrolling is crippling one of the main features? It's a slight annoyance at best.
