How to fix a draining iPhone battery

Phone charging

There could be a number of reasons your iPhone’s battery is draining faster than usual. Sometimes it’s just a matter of patience, whilst other times there could be something seriously wrong with the battery or phone. We’ve put together a quick guide to see how you can get your iPhone’s battery back to normal.


Sometimes it’s just a matter of waiting it out. For example if you’ve just updated your iPhone to iOS 13, your phone will spend a lot of time, and thus power, downloading apps, photos, and other content. Some apps may even have to rebuild their libraries and databases. The same goes if you’ve just upgraded to the brand new iPhone 11 or restored your device. Give it a few days and if you’re still having battery issues, then try one the tips below.  

Reset your iPhone

Resetting your iPhone is often the best way to solve any draining battery issues. For iPhone 8 and later, click and release the Volume Up button, then click and release the Volume Down button, and then press and hold the side (power) button. Earlier iPhones tend to have a different way of resetting, so you’ll need to see which way applies to your device. Once your iPhone has been reset, try testing out the battery for a few more days.

Restore your iPhone

If the reset method doesn’t work, then you can try completely restoring  your iPhone as if it was brand new. Make sure to back any important files and photos you may have. To restore your iPhone, head to ‘settings’, select ‘general’ and then select ‘reset’. In this menu, select ‘Erase All Content and Settings’ and then in the pop-up dialogue select ‘Erase Now’. After you’ve restored your iPhone, you’ll need to set it up as a new device.

Get it repaired

If the above methods have not worked for you, then you’ll need to book your iPhone in for a battery replacement with a specialist repair shop. Head over to to find repair shops near you and get quotes for battery replacements.
