Phone battery issues are the bane of most of our lives. But you kind of just have to get on with it.
However, if you've got an iPhone 6S and are having more trouble than normal then you might be entitled to a new one.
Apple will offer replacement batteries to iPhone 6S owners who find their devices are shutting down abruptly, on the reg.
"Apple has determined that a very small number of iPhone 6s devices may unexpectedly shut down. This is not a safety issue and only affects devices within a limited serial number range that were manufactured between September and October 2015."
And if you already replaced your phone battery you could be entitled to a refund.
