4. 'Good Vibrations', but not always
Fond of your phone vibrating? Might be time to switch it off – it's a major waste of battery. Sure, it's handy when you don't want your phone disturbing your favourite radio show, but you'll be amazed how quickly it saves on juice.
5. Mobile data off, thanks
If you live in a remote area, or far from an area with good WiFi reception, it can be hard to resist switching this button. Refrain. This function is hard on juice and harder on your bank balance.
6. Spare phone battery joy
Android users – were you aware you can purchase a spare battery? Do it. Then, store it in the glove compartment, and you'll be forever grateful.
Remember: Always use a hands-free kit while driving. Having a full battery is awesome, but it won't save your life.
