What are the drawbacks of updating my iPhone 4s to the latest iOS? What are the advantages? With my phone plan, I cannot get the newest iPhone yet.

  • FWIW, I run iOS 8 on my 4S, and don't really see any drawbacks at all. Okay, it is perhaps not quite as responsive sometimes, taking some noticable fraction of a second to react to taps and swipes. It doesn't bother me, but others may feel differently. Feb 22, 2015 at 15:37

  • more security
  • more features: quick reply, continuity (if you have Mac & Yosemite )


  • it will run slowly
  • you won't get a lot of the features that 5S and above have
  • could decrease battery life

If you have experience with ssh and jailbreaking, I would say go ahead but make sure you can downgrade using ssh just in case you don't like it. However, if you don't even know what that is, I wouldn't recommend upgrading because there is no way to downgrade if you don't think you'll like it because apple already stopped signing ios7 and below.
