It is a good idea to "power cycle" (ie. turn off, wait two minutes, turn on) your mobile phone, tablet, notebook computer etc every so often, I usually do mine about once a month.

All these computer type items *will* have bugs in their software and these bugs may, over time, lead to issues arising which may produce very subtle problems. Power cycling will give the software a clean slate to work with.

NB. Do not use a "Reboot" command on the phone/computer but actually turn the power off/on.
