5 ways to improve your iPhone's battery life

The battery life of iPhones has long been a contentious subject so here are five tips for getting the best out of its battery.

Arguably the biggest complaint users have with their precious iPhones is the less than impressive battery you get with the device. 

Every new iOS update creates a bigger strain on your device's battery life, and that strain is even greater if you aren't fortunate enough to own the very latest model.

It has become the nature of the iPhone that after a year or so of use the battery starts getting warmer, charges erratically and begins to barely last a day. Until somebody somewhere comes up with some revolutionary new battery technology (or Apple stops making devices thinner!) this is what we are going to have to put up with.

However, there are ways to combat battery drain. Follow the five steps below and you might just give your battery a whole new lease of life.

1) Turn your brightness down

If I had a pound for every person I saw with their brightness unnecessarily high I definitely wouldn't need to be writing this article. For starters turn off auto-brightness; it has never been a great feature. If you never had it on then great, but you still need to turn brightness down. Under normal circumstances halfway up is more than enough, personally I have mine right under the point of the wifi symbol which is half of halfway and I cope just fine.

2) Turn off Bluetooth

Bluetooth is a feature that doesn't need to be constantly enabled; just like wifi and mobile data, Bluetooth is a guilty battery killer. Sure turn it on when you want to connect to your Bluetooth enabled speaker or handsfree kit, but make sure you turn it off afterward.

3) Turn off mobile and cellular data

Mobile and cellular data is one of the biggest things that can suck the life out of your battery. Turn it off when you don't need to use like when you're at home or any other location where you can access wifi. Both 3G and 4G are big drains on your iPhones battery whether in use of not; when you're on wifi neither is doing anything other than sucking juice out of your smartphone so they don't need to be on. It would have been great had Apple introduced a shortcut button to be able to switch it off in the control centre, but they haven't as of yet, so the quickest way to do this is through settings.

4) Stop allowing apps refresh in the background

Background App Refresh was introduced in iOS 7 in order to make applications more available to use when you need them most. The operating system learns your habits and keeps the apps you use most updated all of the time. It is a nice feature to have but it is a battery killer; going into Settings - General - Background App Refresh you will be able to switch it off entirely or disable individual apps to your own liking.

5) Find the battery killers

In iOS 8, Apple introduced a new feature called Battery Usage. It's a pretty basic feature and it makes you wonder why it has taken so long to implement. What it does is show you the apps that have used the most power over the last 24 hours or last 7 days; what you do with that information is up to you. If some of your favourite and most used apps are on this list you obviously aren't going to want to use them less, but killing the app through the multi-tasking screen every now and then might help.
