When you said, high power n speed, I personally expected better.
I want.to place my phone on a wireless pad/stand and after 30 mins (standard, get home wash n change n go back out time!) Have at least an increase of 30%
Baring mind, after a shift at work etc, phone would prob be about 40% (or less) so a quick boost while you wash change etc would be something I'd look for.
Again, why only apple X, when Sam S8, are selling more and is currently listed on most blogs as the BEST phone out there.
