According to several OnePlus smartphone owners, WhatsApp has been severely draining their devices’ battery life. Users have reported this issue across Reddit, the OnePlus forums, and even in the Play Store, but no one seems to know for sure what’s causing it. There are also reports of Xiaomi phone owners being affected by the bug, too.
The issue appears to have surfaced online within the last couple of days. Apparently, it started sometime after WhatsApp’s latest 2.19.308 update. It also looks like the issue is affecting users across various OnePlus devices on both Android 9 and 10.
Some users have reported WhatsApp using more than 40% of their battery life after hardly using the app at all. Unfortunately, we have not been able to replicate this behavior on any of our OnePlus devices to have a look at the WhatsApp battery drain issue ourselves.
Android Authority reached out to WhatsApp for comment but did not hear back by press time. We will update the article when we receive a response.
