What's wrong with TikTok ?

I have a Motorola Power G 2021 it's a great phone though when I install TikTok the battery drains fast also fills up space when I don't hardly have anything I don't have games photos just my 78 social media apps. When I delete it my phone goes back to normal it's been doing this for 2 weeks it's never done this before it just started recently. What's going on ? Anybody else with TikTok have this problem ?
