Android Phone have massive lag spike starting this morning?

[fos1x]

- Xiaomi MI a3, stop receiving OS or security update year ago, I doubt it was some google update with the google app

- Just change new battery 3 days ago, phone behave normal, charge a bit slow but hold charge so much better than the old one.

- I was curious, so I download some CPU monitor app, it displays my CPU is hover between 50-100%???, I don't have control test, so I don't know what "normal" look like, is there an app monitor to show which app is running right now?

Oh... think I found the culprit... heck, why is this even happened?

I just uninstalled this very popular app that I bet a large amount of android user have it! And my phone act normal again, what the heck? This App is Apkpure, a legit third party app store?

I remember using apkpure on my amazon fire tablet... within a week it became unusable until I uninstalled it. I think apkpure is legit but it has some problems with background usage, I bet it just is because it keeps checking for updates and updating your apps in the background, as well as poor optimization. After a few weeks it even makes my s22 ultra near unusable.
