Exactly the same issue with a USB-C dongle.
When on battery, severe CPU throttling kicks in at 35% charge: how to change ?

Brand new Spro7, Firmware up-to-date.
I noticed drastic CPU throttling when battery charge level reaches 35%: CPU tops at about 0.5 GHz and setting the power slide to "Best Performance" doesn't change that.
I found no setting that would allow to change this excessively conservative threshold to something more reasonable like 12 or 15% (my Battery Saver level is set at 15%, but it has obviously no impact on this).
Is this hard-coded in the firmware ?
Any ideas ?

2020-05-20T20:57:12+00:00 I have the same issue, I had thought initially that it was my imagination - but on battery, the surface pro 7 i5 throttles quite badly and sits at 0.5Ghz and even basic tasks are just sluggish. It's good to read it's not just me and that its potentially not a hardware issue.
Here's hoping this gets fixed soon.

2020-05-20T22:11:20+00:00 Same issue here. I thought this was a temperature issue but now realise its when battery gets around the 30% mark. Could really do with a solution to this. When your on battery that last % is unusable.
