Acer Chromebook 15 and 11 Battery Questions

Jandus

I own two Acer Chromebooks.
I own the Acer Chromebook 15 (CB515-1HT-P39B) and the Acer Chromebook 11 (CB311-8H-C5DV)
Both of these devices are less than a year old and the battery percentages are acting very strangely.
With the Chromebook 15, it started at over 99% and then after a single reboot it dropped all the way down to 91% and has stayed there every since with less than 20 cycles.
As for the Chromebook 11, it's even more odd - It also has around 25 cycles and is less than a year old and is now down to 76%.
I've never had any other laptop battery act this way.  Is it possible the 'battery_test' is faulty?  Or are the batteries in these devices just very low quality?

Any ideas?

Let me know if you need any more information.

Not faulty. Just not an accurate test. As for the CB15 you can try to reset the battery https://us.answers.acer.com/app/answers/detail/a_id/34843/~/acer-internal-battery-reset. As for the CB11, losing (an estimated) 25% capacity in the first year is not unusual by any means even if it was plugged in the whole time and not cycled at all.   Jack E/NJ
