How to speed up your iPhone – five top tips

If you’re a long-time iPhone owner, you may notice your smartphone slow down as it ages. Here’s how to keep your iOS experience a smooth one.

Over time your iPhone can become increasingly sluggish, running slower than it did when you first took it out of the box. There are a number of reasons why this can happen, from a build up of downloaded apps to out-of-date firmware.

Take a look at our collection of top tips that will help you speed up your iPhone and keep it feeling fresh.

1. Try Low Power Mode

Last year’s iOS 9 update added Low Power Mode to the iPhone, making it quick and easy to turn on some power-saving features with a single, magical tap.

Enabling Low Power Mode on the iPhone will temporarily disable certain processes that drain battery juice, such as automatic scans for new emails, Siri functionality and background app refreshing.

Certain visual effects are also disabled, including dynamic wallpapers and perspective zoom. Turn on Low Power Mode in Settings under Battery and see if you notice a difference.

2. Disable animations

If you don’t mind sacrificing some of the more visually appealing aspects of iOS, try disabling animations to make your iPhone quicker.

Under Settings, hit General and then Accessibility. From there, head to Increase Contrast and toggle Reduce Transparency. Doing so will make your icon dock, Notification Centre and Control Centre opaque.

Elsewhere, the zooming effect visible whenever you open or close an iPhone app can also be disabled. Toggle Reduce Motion on the Accessibility menu to turn it off.

3. Tidy up your iMessages

If you’re a self-confessed texting addict, it might be worth using those busy fingers to journey to the Messages menu on your iPhone, where you can tell the smartphone to automatically delete old messages after a certain period of time.

Under Settings, tap Messages and then Keep Messages. From there, you can choose to keep text messages for 30 days, one year or forever. Deleting old messages will have an especially big impact on performance if you’re a habitual sender of video files or audio notes to contacts.

4. Be ruthless with apps

Hoarding apps on your iPhone that are rarely used doesn’t do much for the speediness of your phone, but thankfully iOS can list apps by how much space they take up and by how power-hungry they are.

Tap on the Settings icon, then General, then Battery. On this page, you’ll see just how much of an impact each of your apps have on the iPhone’s battery life. Going back one step and tapping on Storage & iCloud Usage will show how much space is left on your device.

5. Keep your iPhone updated

Running old versions of iOS can mean dealing with pesky bugs that have since been wiped away in newer builds. Make sure your iPhone is up to date by tapping on Settings, then General and finally Software update.

If you’re still dealing with an abnormally slow smartphone after trying out these tips, a hard reset may be in order. Force your iPhone to reboot by holding down the Home button and Sleep/Wake buttons at the same time, releasing them both when the Apple logo appears on screen.

A trip to the nearest Apple Store is recommended if all else fails.
