iPhone slow running or lagging is a situation where it takes more than normal time for an app to open or load in any iPhone. Moreover, this observation is often occurring after a Smartphone has been used in some period of time.
1. Clear your RAM
The RAM is the activity storage place of your Smartphone. It is measurable and every installed App needs specific size of it for operations, so too many Apps will reduce availability size of it. (see How to Check iPhone RAM Size)
- Press and hold your iPhone’s power button until the “Slide to power off” bar appears. DO NOT POWER OFF YOUR iPhone. Instead….
- Release the power button and now press and hold the home button for five seconds until your home screen comes back on. You RAM will now have been refreshed and your iPhone should be much faster.
2. Clear the cache from the iPhone’s built-in apps
Another thing that can slow down your iPhone are cache files. These are files that store data so an app can quickly access that data next time without have to go looking for it or creating it again. In theory this will lead to speedier apps. However, large caches, over time, can actually slow down your iPhone.
Not all apps allow you to clear the cache, but Apple has built a secret feature into its pre-installed apps that let you clear their cache. Here’s how:
- Open a preinstalled app. These include apps like App Store, iTunes Store, Music, Podcasts, Game Center, iMessage and Phone.
- In the tab bar (the bar where the app’s buttons are) in any of these apps, tap the same button (it doesn’t matter which) quickly 10 times in a row. The app will now flash white and its cache will be cleared.
3. Clear your iMessages
Believe it or not, but having a ton of iMessages can massively slow down your phone—in addition to taking up space.
You can check how many you have by going to Settings > General > Storage & iCloud Usage > Manage Storage. If your iMessages are taking up more than 1GB it might be time to delete them.
To ensure iMessages never become a storage or speed hog in the future, it is best to set iMessages to auto delete after a set amount of time. To do this:
- Go to Settings > Messages > Keep Messages.
- On the Keep Messages screen choose 30 Days or 1 Year (if you want to keep them for a bit longer). Choosing either one of these options will delete all your older messages past that timeframe—and in the process speed up your iPhone.
4. Disable animations
Apple introduced some cool motion and animation effects called Parallax back in iOS 7. While they look cool, making your iPhone carry these out each time you open an app drains both the battery and requires your RAM and processors to work harder, slowing down your phone. If you don’t need the eye candy it’s best to disable the animations. To do this:
- Go to Settings > General > Accessibility and toggle the “Reduce Motion” option to ON (green). Now animations will be less pronounced (or gone altogether).
- *To download every app from your play store and read the terms of usage.
- *Do not use transfer apps from friends to avoid contaminating virus or malware.
- *Before the installation of any app, check the remaining size of your RAM (For android, click here for the steps), and iPhone, click here, if it still remains sufficient.
- *Uninstall Social Apps that you do not have account with.
