A bug introduced in Android 8.1 Oreo is causing some Pixel XL devices to overcharge

Some Google Pixel XL units are suffering from a charging bug that sees them receive more power than they should. According to a Reddit post 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 charger will then drop the current (it’s designed to avoid overcharging) before attempting to resume the intended power delivery again. It’s said that this cycle can happen multiple times before the charging settles at the correct level—if you’ve spotted the “charging rapidly” notification pop up a few times when plugging in your charger, that’s why.

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 Oreo.

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.
