Does not updating ios on an iphone (iphone 7) result in faster battery drainage?

Does not updating ios on an iphone (iphone 7) result in faster battery drainage?

No. The drain would be a result from a rogue app/software, a worn battery or aggressive device settings.

Not upgrading would not increase consumption - you didn't change a thing.

Updating them phones seems to give more problems then anything else

  • Will updating my iPhone apps affect my phone speed as how updating the Operating System (OS) will? Currently I'm using the iPhone 5s on iOS 8.3 I know if I were to update my phone to the latest OS I may notice some slowdown on my phone's performance, since it may not have the "muscle" to handle certain functions. Many apps now are optimised for iOS 9 and/or the 6th generation phones. Will my 5s' speed performance slow down if I update my apps? Will the app's performance slow down?
  • Restoring my iphone? Battery drainage? So lately my iphone has been draining battery so fast. And i have looked up that i should restore/restart it. But if i do that will i lose my apps?
