It also looks like the issue is affecting users across various devices including OnePlus 7 series, OnePlus 6 series, as well as some Xiaomi, Samsung and Pixel smartphones.
Even Android 10 version app is causing the issue
Some Android users have also highlighted that the problem is not exclusive to just the Android 9 version of the app and that those running Android 10 are also getting affected by this WhatsApp background activity issue.
What is the solution?
Even though the problem seems to be affecting a lot of users, WhatsApp hasn't acknowledged the issue. However, until the company addresses this concern, you can try some hacks to control the battery drainage.
Firstly, re-installing WhatsApp may help you get rid of the problem. But if it doesn't, you will have to kill WhatsApp in the background once you are done using it.
