iOS 9 is slow...

[trparky]

I don't know what's up with this thing but almost everywhere I go in iOS 9 on my iPhone 6 Plus there's sluggishness and hesitation. In the Fast Task Switcher, which I prefer the iOS 8 way better, it seems the most visible.

Never had this issue going from one iOS 8.x version to another. Almost makes me want to go back to iOS 8.4.1 and let Apple come out with iOS 9.0.1 to fix bugs.

Try a restart. Home and Power. It smoothed things out for me.

Did that twice already. Still seems sluggish according to iOS 8.4.1. 8.4.1 ran like butter. 9.0? Not so much.

My battery life has also taken a major hit.

I thought I was the only one! But yeah it is a bit slow especially in the task manager animations and switching. I have the same phone too, iPhone 6 Plus.

Might need a restore as new. I always end up doing that after a major iOS update. Haven't had a chance to judge battery life yet.

When you say "restore as new" you don't mean restoring a backup, right?

Part of installing an iOS update is that the system has to do some tasks like indexing that takes system resources and makes the devices run a little slow... and this process can also hit the battery... and then there's the "exploration" factor - new iOS, new features, and we tend to want to find/see/test them all.

It will get better within a day or so.

Reminder: When you install iOS 9, a lot will update, migrate, and index. Battery and performance will take a temporary hit. Give it a day.

Yeah, I had no issues with speed or battery life.

Right not from a backup.

My 6+ is super laggy since update

 

[Garz]

It's due to the lack of ram. My Air 2 with twice the ram is much snappier than my 6+.

Did you install with iTunes?

Hopefully the 6S+ has more ram or this is going to be a major fail. Smh.

Ipad Mini 2 has some noticeable lag... as opposed to my iP6... runs alot better on the iP6...

 

[joaoluizmf]

Same here.
Fresh new install (no backup restore).
I was using 9.1 beta, and things were running perfect..

 

[vincie76]

Notice too. Maybe I will go back to 9.1. it seems battery is draining faster

Yea my 6+ is jerky as hell. I have some cash to burn so I might trade it in for a Note 5 this weekend. Don't want more hardware limited user experiences. I prefer not having to worry or care about these things.

Android? Please... Don't make me laugh. Trust me, you don't want to go to that garbage heap of software known as Android, it's a piece of crap covered in crap.

 

[trparky]

If anything, get the iPhone 6s if you really want to trade in your phone. Just don't get an Android. I will never use an Android ever again. After the four Android devices that I used that all had much worse issues than iOS 9 has, I told myself "never again".
