Is WhatsApp too slow or doesn’t open all chats properly? Let’s see how to recover performance by clearing the app cache from Android and iPhone

Cache WhatsApp

The apps installed on the phones accumulate data with each use, keeping them in a dedicated section of the internal memory called “cache”. WhatsApp is no exception to this rule: the popular messaging app quickly fills cache on Android and iPhone every time we open chats and groups, even without replying to anyone (just open the app to have an increase in busy cache).

In the following chapters we will show you how to clear whatsapp cache on android and iphone, using both the methods built into the operating systems and the methods provided by the WhatsApp app itself. For those who want to use an app we will show you how to use the built-in cleaners on Android phones and the best apps that can clear WhatsApp cache quickly.
