Should i update my iphone 6 64gb to ios9?

I got a lil phobia of updating phones, anyway is there chance my phone could get slow? After updating to 8.4 it already showed problems (notification/control center often became un accessible). Is there anyone who is having troubles with his/her iphone 6 running ios9?

If your phone was older I would say don't bother but as yours is a 6 I would say yes. I do however always think you should minimise your on phone storage and cut back on pointless apps. Run something like MobileGo to tidy / speed it up

Either wait a few days for a further update -or wait until mid-October for the 9.1. There have been problems with iOS 9 (Really? Like that NEVER happens?) and it has taken up 2 days to find/fix many of our needs - and we're not done yet. We also did this to a 6. And you can also keep 8.4.1 - or roll it back if you try 9 and it messes things up. JUST WAIT - a few days, or a few weeks. 9 has not a whole lot that is spectacular - I'm not impressed one bit. And several things are REGRESSIVE _ more work than they are worth.

  • Why won't my iPhone 4s charge properly after ios9 update? I updated my iphone4s to ios9 a few days ago and ever since then, it hasn't been charging properly. I'll plug it in and it'll go up to 80 percent and it won't go past that. I've had it plugged in all afternoon (about 8 plus hrs already) and it's still at 80 percent. Is there a way I can fix it? Is it because of ios9?
  • Iphone froze because of ios9 update? I "updated" my phone hours ago and it still hasn't turned on! It says "update complete" but then It freezes on a white screen that says "slide to update"… I have tried pressing the lock and home button, connecting it to my laptop, and plugging it in, in different outlets. I need my phone for school and work by tomorrow!
  • IPhone 6S 64gb or iPhone 6 Plus 64Gb? IPhone 6S 64gb or iPhone 6 Plus 64Gb. I already have a 6 but I really need the storage. Should I order a 6S or get 6 plus instead?
  • If i install ios9 beta, will i have to go back to ios8 when apple comes out with the actual ios9? I want to install the beta of ios9 but i worry that i will have to revert my iphone back to ios8 before i can go to the actual ios9 - when it comes out.
