yeah probably 9h but way more Wifi than you but I'm using Tapatalk, Facebook, Instagram, Snapchat (all 3 Apps not often), News, Reddit etc. Probably the social media apps burn more battery + using Nuki Smart Lock with Auto Unlock if I'm near my lock.My main apps were twitter, Tapatalk (which is what I use for these forums pretty much when on my phone) Reddit and just the odd sports apps. So mainly twitter, Tapatalk,Reddit are my main apps
Looks like you were well on the way for 9 hours as well if you ran it down
