Maximising iPhone Battery Life
‘Battery life’ is the amount of time your device runs before it needs to be recharged. ‘Battery lifespan’ is the amount of time your battery lasts until it needs to be replaced. Maximise both and you’ll get the most out of your iPhone, no matter which ones you own. Here are a few tips to maximise battery life.
Remove certain cases during charging.
Charging your device when it’s inside certain styles of cases may generate excess heat, which can affect battery capacity. If you notice that your device gets hot when you charge it, take it out of its case first.
Store it half-charged when you store it long term.
If you want to store your device long term, two key factors will affect the overall health of your battery: the environmental temperature and the percentage of charge on the battery when it’s powered down for storage.
Do not fully charge or fully discharge your device’s battery — charge it to around 50 per cent. If you store a device when its battery is fully discharged, the battery could fall into a deep discharge state, which renders it incapable of holding a charge. Conversely, if you store it fully charged for an extended period of time, the battery may lose some capacity, leading to shorter battery life.
Update to the latest software.
Always make sure your device is using the latest version of iOS.
Optimise your settings.
There are two simple ways you can preserve battery life — no matter how you use your device: adjust your screen brightness and use Wi-Fi.
Dim the screen or turn on Auto-Brightness to extend battery life.
When you use your device to access data, a Wi-Fi connection uses less power than a mobile data network — so keep Wi-Fi on at all times.
Enable Low Power Mode.
Introduced with iOS 9, Low Power Mode is an easy way to extend the battery life of your iPhone when it starts to get low. Your iPhone lets you know when your battery level goes down to 20 per cent, and again at 10 per cent, and lets you turn on Low Power Mode with one tap. Or you can enable it by going to Settings > Battery. Low Power Mode reduces display brightness, optimises device performance and minimises system animations. Apps including Mail will not download content in the background. When your phone charges up again, Low Power Mode automatically switches off.
