But according to Apple, “i OS 11.2.2 provides a security update and is recommended for all users”.
This is because the update is designed to mitigate the effects of Meltdown and Spectre, the security flaws that can cause problems for i Phone users.
If you do find your apps slowing, though, try upgrading to the latest version of i OS to see if that sorts the problem.
Conversely, updating your i Phone to the latest i OS could cause your apps to stop working.
For now though, if you have done the update and are now finding that your battery can barely make it through a five-minute phone call without giving up, try the i Phone battery replacement programme.
In the past few months, Apple has released frequent updates to i OS 11. For most people, it's a personal preference, but there are some people who should definitely steer clear. When Apple released i OS 11 in early September, I was still using i OS 9, and my phone was still running like new.I held off on upgrading to i OS 11 for as long as I could, worried about rumors I'd heard that it would decrease my outdated phone's performance.Eventually, however, I gave in to pressure from friends and colleagues, plugged my phone in, and upgraded.But it should to help fix a few of the bugs that blighted i OS 11.Unfortunately, it won’t restore battery life for those older i Phones hampered by the latest update.All you need to do is make an appointment with an Apple Genius for a battery replacement and they’ll do it for you in store.It’ll cost you £25, which is significantly cheaper than the £79 they normally charge for a new battery.Many early adopters find that they experience bugs and other issues when they first download the latest software update.And Apple will often roll out subsequent updates that include fixes to the bugs in the previous software upgrade.My phone's performance and battery life were immediately reduced to shells of their former selves.I now need to charge my phone about three times a day, it shuts down without warning, and it crashes when I have too many apps running.
