Android 8.1 Oreo bug causing overcharging on Pixel XL (2016)


  • A bug introduced in Android 8.1 Oreo is causing some Pixel XL (2016) devices to overcharge.
  • The affected Pixel XLs are pulling 25W of power instead of the 18W, which could damage the handsets.
  • The issue has been raised in the Google Issue Tracker but a solution hasn’t yet been provided.

Some original Google Pixel XLs are suffering from a charging bug that sees them receive more power than they should. The problem was brought to our attention by a Reddit post (via Android Police) created last week, where users discussed the potentially dangerous issue.

The problem is said to have occurred following the Android 8.1 Oreo update; when charging with the supplied charge cable, some Pixel XLs are drawing 25W (9V/2.8A) of power instead of the 18W (9V/2A) that they should.

The problem was raised in Google’s dedicated issue tracker at the end of January where it was suggested that it was “an issue with the battery charge controller logic” introduced in Android 8.1. A solution hasn’t yet been provided, though it’s something that seems like it should be prioritized—many of you will be aware of the damage that can be caused from power/battery mismanagement.

For those who are affected, you can try using a charger with a different spec until a patch is issued. Manufacturers generally recommend using the supplied charge cable with electronics devices, but another reliable USB Type-C charger might not create the same problem.
