Hey guys, I’ve been on iOS11.x for sometime now including latest 11.1 but I’m just not happy with the battery life. I would like to downgrade back to iOS10.3.3 but without losing any of the apps, data, media, etc. I read that there was a away but I don’t want to risk it without being absolutely certain that my WhatsApp contents remain intact including the media most importantly. I’ve done a backup but that’s only good for iOS11 versions. Appreciate any help. Thanks.
