Re: what is ios 8 minimum requirements
So realistically, any iPhone that is really still worth using?
The 4s is still worth using, but not for long. A 5s would last much longer with the operating systems. But if you do get a 4s, read over these suggestions.
To help your 4s run as smooth as possible, try these suggestions.
1. Leave 20% or more of your internal storage space free. This helps to not constrain the system.
2. Get rid of unnecessary features. Yeah, some are cool, but they will bog down an older model phone.
3. Disable transparency effects. Toggle on "Increase Transparency" in Accessibility.
4. Toggle off "Background App Refresh".
Good luck.
