6 things you can do to give your devices a spring cleaning

Cached data lives in your device after you open an app or visit a website for the first time. The collected data helps your device gather information about an app or website so it doesn't take as long to load.

“Cached data is information that is stored on your mobile after visiting a website. Developers use cached data to improve your online experience, and the files in your cache are usually small,” Hiley says. “But over time, they can impact your device's speed.”

According to Hiley, a stockpile of cached data can slow your device's performance. So, every now and then, consider clearing your device's cached data. However, when you open websites and apps after clearing the cache, they'll just be reloaded onto your device. So this solution isn't incredibly useful if you're really low on storage.

Luckily, ZDNET can guide you through how to clear the cache on your iPhone and Android phone or tablet.
