Has anyone had an issue with Acer 311 Spin batteries reporting they only have about 6% battery health and an hour of charge when fully charged?  The devices appear to run long after the battery has reported itself as having no battery left.  If so, does anyone have a fix for this issue?

    Is this a Spin Chromebook or a Spin Windows? That's pretty common on Windows, less so on the Chromebooks.

    I had the model incorrect.  It looks like it's the 311 chromebooks (N20Q9)

    OK, we don't have a cross reference for those numbers, but a Google search indicates it is likely a C722-xxxx. Use a Ctrl-Alt-t key combo to get crosh opened, the type battery_test and hit return. It's best to do that with the charger off, but it takes a full five minutes to complete. What does it say for battery health? Next do a battery_firmware info and look at the number of cycles it has seen and how the last full charge compares to the design capacity.

    The device reports the battery health at 5.93%.  This is consistent with a number of the devices having this issue.

    Design capacity: 3713 mAh
    Last full charge: 221 mAh

    Cycle count: 18

    The battery will last long after the reporting stats claim they will

    Most of these machines are on OS version 97.0.4692.77

    I hope Google will fix the inaccurate numbers in a newer OS version then.
