To delete WeChat friends in batches, you can follow the steps below.
First, open WeChat and enter the "Address Book" page, find and click the "Search Box" in the upper right corner, and enter the name or remarks of the friend you are looking for.
In the search results, press and hold the profile picture of the friend you want to delete, then select "Remove from friends list."
In order to manage friends more efficiently, you can use the grouping function provided by WeChat to group friends and delete them one by one, so that you can clean up infrequently used friends in a more systematic way.
Please note that frequent batch deletion operations may cause misjudgments by the WeChat system, so it is recommended to appropriately control the deletion frequency.
