What you need to knowPixel 10 Pro Fold users report battery icon displaying a mysterious question mark.The bug could be linked to wireless chargers, possibly affecting the battery management system’s calibration.A temporary fix is available through a reboot, but Google states that a fix will be rolled out with the November monthly update.

Google’s latest foldable seems to be facing a peculiar bug. Several Google Pixel 10 Pro Fold users on Reddit have reported seeing a mysterious question mark(?) instead of the percentage.

This issue seems to be cropping up for users who have wireless chargers, particularly third-party or non-Qi2 certified chargers, but this is still speculation(as first spotted by Piunika Web). The rumor on the street is that these chargers might’ve caused a “brief communication or calibration error between the battery management system and the software interface, resulting in the phone being unsure of the current battery level, hence the question mark,” the publication added.

9 Pro Fold users also seem to have spotted the weird ‘?’ icon next to their battery, where one user stated that the error message they got was “Unable to read battery meters”. The user seemed to have contacted Google support, who said they’re sending him a new device.

So could this really be a battery swelling issue on the new Pixel 10 Pro Fold? Only time will tell. But for now, if you’re seeing this issue, a temporary fix, all you have to do is to reboot the phone, which returns the correct battery percentage. If you still don’t see it fixing this bug, you should contact Google Support for further guidance or a possible warranty claim.

Google’s spokesperson also confirmed to Android Central that rebooting the device will resolve the issue; however, “Pixel 10 Pro Fold users should use certified Qi2 wireless chargers.” And that a fix for this battery bug will be rolling out with the November monthly update.
