In the hills, away from power, battery anxiety is a common condition, particularly when camping. Smartphones in particular are incredibly power hungry, and many have apps and functions that run in the background and suck power even when you're not using it. How you use your phone on the hill will dictate how many of the following you can do… but all could ensure you have juice left when you need it most.
Put it in flight mode. This saves the most battery as it switches off all connections coming in or out of your phone. You can still use the camera, but you won’t be able to use navigation apps – and nobody will be able to call you.
Turn off Bluetooth and Wi-Fi. Two big drains on battery life, and both useless on the hill.
Turn the screen brightness down. It will make it harder to see in the daylight, but you can always turn it up if needs be.
Switch off ‘background app refresh’. This is the updating of phone applications while you’re roving about. Sucks battery and uses data as well.
Buy a backup. If your phone has a removable battery, buy a spare and keep it charged. Alternatively, a huge range of companies make power banks, from the pricy ones by Brunton and Goal Zero to the cheapos in service stations.
Turn it off. Yes, it is possible. Make sure you tell people that contact will be on your terms, though.
