Restoring from iCloud backup. Battery life in new phone affected? Fact or myth.

[CosmicRichy]

As the title says. Has anyone been able to actually prove this?

I've always set up my iPhones as new phones but yesterday I restored from an iCloud backup after finally purchasing the iPhone 7 Plus after my 6 Plus's battery basically failed.

I've always seen posts on here saying never to restore from a backup because the poor battery life will carry over to the new phone.

I'm currently on the first charge cycle with 25% battery left. 21 hours standby, 8 hours usage. I've used facebook and Pokemon Go a lot in that time. Also made a FaceTime call that lasted around 15min.


My iPhone 6 Plus would of died hours ago...

All of those can be considered as myth. No statistical analysis, no systematic tests, no collective results. These are purely based on experience and they are way too complex, well, you know, I can say everyone's experience is right or wrong and I am not entirely wrong.
Use your own experience to tell. If it is okay, it is okay.

When I got my 7 Plus I used a iCloud back up from my 6 Plus that went back to my 5S. With no battery issue. I just recently restored as new on my 7 Plus and see no significant battery improvement.
