According to a repair expert who specializes in restoring old phones, most people ignore the main reason why phones are so slow. Daily Mail.

Programs running in the background

Many apps run “invisibly” in the background, which can slow down a device, says Kevin Charron, senior manager of retooling operations at BackMarket.com.

There are also a number of battery optimization features that most users are completely unaware of. Fortunately, on both iOS and Android, it’s easy to turn off battery-draining apps and optimize your phone with a few simple tweaks.

He also said that users are now using more apps than ever before.

Apps can also run “in the background,” eating up the phone’s RAM and processor — and slowing down the entire phone without you noticing, Charron explains.

What can users do so that the phone does not “slow down”.

To prevent your phone from running slow, you should go into your phone’s settings menu to restrict apps that can or cannot run in the background.

“Both iPhone and Android users can adjust their settings to automatically monitor and stop apps running in the background.

Apple users, go to Settings > General > Background App Updates and select Wi-Fi, Wi-Fi & Cellular Data, or Off to completely disable background app updates.

Likewise for Android users: To see which apps are running in the background, go to Settings > Developer options > Running services. You can then close those apps by going to Settings > Apps, select the app you want to stop, and then force stop.”

First, you’ll need to turn on developer options — find “developer” in the settings menu, then turn it on (how to do this depends on the phone you’re using).

Charron said that “this should have an immediate effect on the speed of the phone.”

Phone memory is full

Another classic reason for a slow phone is when the phone’s memory is almost full, which can slow things down, warns Charron.

“Phones need about 10% of available space to store cache and temporary files, which allows apps on your device to run smoothly,” he added.

“Having free storage space also means you can keep your phone’s software up to date.”

To free up space, Charron recommends uninstalling old apps — especially games that take up a lot of space — and deleting videos or moving them to the cloud.
