With a uniform design throughout, OxygenOS 13 offers a wealth of functions that seamlessly integrate with the whole software environment.

And if you have recently updated your OnePlus device to the Android 13-based OxygenOS 13 operating software, you’re in for a number of features like AOD, Smart Sidebar, and more.

However, like any other update, it is also not immune to various bugs and issues.

OnePlus 9 battery drain issue after OxygenOS 13

After installing the Android 13-based operating system, OxygenOS 13, some OnePlus 9, 9 Pro, 9RT, and 9R users (1,2,3,4,5) claim to be experiencing problems with the device’s battery life.

Reports suggest that the battery of their devices is draining at a remarkable rate. It even fails to make it through an entire day sometimes.

For some, the issue of sudden and rapid battery drainage is also accompanied by abnormal heating. Interestingly, we previously highlighted a similar overheating issue for some OnePlus 9 users.

This is incredibly frustrating for users as they are now required to charge their phones every now and then.

No official word in sight

Unfortunately, OnePlus hasn’t acknowledged the OnePlus 9 battery drain issue after OxygenOS 13 update.

We hope that the developers come up with a fix soon so that it can keep OnePlus 9 series users from the risk of damaging their smartphones.

We’ll keep tabs on the latest developments and update this article as and when something noteworthy comes up.
