Apple is examining a bug in the iPhone 6S that can root
it to show the incorrect quantity of battery life while you're travelling
– however there is a fix for anybody who runs into the difficulty. The mistake happens
when the cell phone switches time
zones mechanically, or when you alter the time on the gadget yourself. Several
users are finding the battery percentage is not updating, although the charge
is dipping.

To fix the subject, the Apple Support page proposes you restart
your iPhone,
and once it has booted up exit into Settings > General > Date
and Time and confirm 'Set
Automatically' is put to On.
Stuck in time
If the trouble perseveres even when you're not altering time zones, the suggestion is to
contact Apple support. Apple declares it's conscious of the
matter and is discoveing ways to fix it – we'd expect for a fasten to approach
in iOS
9.2.1, though we're not certain yet when we'll observe that.
It's not the main matter for the enormous bulk of iPhone
users, however it could be chiefly annoying if you journey a lot.
