Android browser history typically retains records of your browsing activity for as long as the app itself is set to keep them, which can vary by browser and user settings. Generally, most browsers store history until the user manually clears it or until it reaches a predefined limit based on the number of pages visited. Users can often adjust these settings in the browser's privacy or history sections. Additionally, some browsers may sync history across devices if signed into an account, potentially extending the duration.
