iPhone 5S battery drain when switched off
Hi,
Switched off my phone last night at 10.45pm with battery showing 26%.
Woke up at 5am and switched phone on with battery at 19%. Drain accelerating down to 14% over 10 minutes with light 4g internet usage. Phone is barely 3 months old. Any ideas why battery would drain 7% whilst off for 6 hours?
