Risks of Clearing App Cache:

  • Bye-Bye Saved Stuff: Clearing cache means that some of the stuff your app remembers, like high scores in games or your login info, might go away.
  • Log In Again: Do you know how your apps usually remember you? Well, after you clear the cache, you might have to tell them who you are all over again by logging in.
  • Slower Apps for a Bit: The first time you use an app after clearing its cache, it might be a bit slow. This is because it needs to get all its info again.
  • Using More Data: When an app has to grab all its info again, it might use up more of your data if you’re not connected to Wi-Fi. (Learn how to save mobile data)
