There's nothing worse than going to leave the house to find your phone battery is below 20 percent.
A lot of our lives are all stored in our devices - from bank cards and train tickets, to important phone numbers and WhatsApp.
With this in mind, it's understandable that a sense of dread washes over you when you look down to see your iPhone battery life in the red zone.
For those of us who don't have nifty charging devices on hand all the time (or if don't want to spend a small fortune in Starbucks so you can access a charging point), there are ways you can limit the chances of your battery dying on you when you least want it to.
Apps
While you'd think closing apps that are running in the background of your iPhone would help maintain its battery life, it turns out that closing them is more of a hindrance to your battery.
Advert
Swiping apps up to close them actually causes your iPhone to slow down - something that's been confirmed by Apple.
On its discussion forum, Apple explains: "When your recently used apps appear, the apps aren’t open, but they're in standby mode to help you navigate and multitask."
Some apps you've recently come out of will run 'for a short period of time', but as soon as they fall into that suspended state, they aren't 'actively in use, open or taking up system resources'.
Low Power Mode
Ok... this one is kind of obvious. By using Low Power Mode on your iPhone, it automatically deactivates a lot of the device's battery-draining features.
Advert
To turn Low Power Mode on or off, go to Settings, then Battery. You can also turn Low Power Mode on and off from Control Center. Go to Settings, then Control Center, to Customize Controls, and then select Low Power Mode to add it to Control Center.
Low Power Mode will turn itself off once your iPhone (or other Apple device) is charged at 80 percent or more.
Disabling 'Hey Siri'
While Siri might be your best friend, using him a lot it can affect your battery life.
This is because Siri is constantly listening and waiting for you to say 'Hey Siri'.
Advert
Siri uses the an iPhone's display, the network, the speakers - all of which drain battery life.
Keyboard haptics
Keyboard haptics are a bit like Marmite: you ever love it or you hate it.
Haptics are when you type on your iPhone and you get feedback from the device, almost like a buzzing sensation.
Advert
With the buzz in mind, each time you press a key it'll drain your battery life; so if you plan on typing a short monologue to your pal about your weekend antics, maybe turn haptics off.
