iPhone 6s Plus Owners...

Is your phone still running really stable and quick? I have a 64 GB 6S Plus and it's been slow as **** lately... I can't run more than 5 apps without severe lagging.

Not sure if the fact that I have only 2 GB of storage left has an impact on that?

Try a factory reset. I had that problem with my 128GB and doing that made it like new again.

Mine is working fine on iOS 11. Haven’t noticed any significant slowdowns. I do a full backup in iTunes and a restore every month and it clears up a lot of space each time. I’d try that!

You never indicated if you updated to iOS 11 or not.

Yes I did... and it has been slow before and after the update.

If you have not already, I would take the advice from the other forum member and try a factory reset.

Running out of storage can cause slowness issue. Try to clean up the phone a bit (e.g. back to 10GB free space), and then perform a reboot, wait a for a night to let TRIM + GC to do it's job, then try again to see if the speed back to normal again.

Since you mentioned about "open 5 apps", so I assume it's more capacity related than anything else. But anyway, you can till try if plug in power cable make any difference. If yes, then the battery is dying.
