Hello.
I had a problem with WhatsApp consuming battery excessively. I've searched the internet on several forums but could not find a solution to help me.
As you can see in the screenshots below (they're in portuguese, but the time is visible), the active usage time of WhatsApp has exceeded the screen usage time. I don't know if this is possible but it happened, as well as it can be seen in the second image, the time in the background is very high.
Only solution that helped me with the time in the background was to silence all status. I keep receiving message notifications normally, and the battery consumption is much lower.
It appears that when status is enabled, WhatsApp downloads the first ones from each contact for instant view. This can be seen when you open the Status folder in a file manager and have statuses that have not yet been viewed.
Silencing the Status of the contacts, WhatsApp only download if you click to view the status. This causes it to not run in the background looking for status updates and downloading automatically.
