...I have the i phone 6 up and running ...
Bought a refurbished 6 last year, good phone.
One thing on battery. Phone settings told me battery health was 89 per cent, ie the level it recharges too compared with new.
Happy with that for secondhand phone and my light use.
Worked fine for many months, easily getting through a day but then two months ago was gone suddenly gone by lunchtime.
Went to local phone battery specialist and his tests said battery health was 26 per cent! 89? 26? near enough
New battery, 65 bucks, 100 per cent and now barely half used by bedtime.
