Hi, Just wondered if someone could give me an idea of what kind of battery stats you are getting with a 5S on iOS 10.3? Got a secondhand back up 5S today from Giff Gaff while my 6S+ is off for repair. So far I'm not very impressed with the battery I'm seeing. On WIFI I'm seeing 70% left, 1hr 44min usage and 2hr 5min standby. Safari, bit of Twitter and Facebook Messenger. Is that pretty regular for this phone?
