As with any electronic now and again your battery could seem to be draining a little faster then usual. This is especially the case with older devices. Did you know cycling your battery once a month can preserve your iPhones battery life? Cycling a battery is a fun way of saying let your battery run all the way down then charge it back up again uninterrupted. Once a month when you find the time let your battery run below 10% and allow it to charge uninterrupted (preferably overnight). Just by doing this you should see a noticeable change in your device batteries performance!
