Feature Request: Ensure New V have Battery Limit control

So, my old Surface Pro 4 (sadly I discovered this only few days ago) has a UEFI control option to “Enable Battery Limit Mode” https://docs.microsoft.com/en-us/surface/battery-limit

This seems to be keeping my battery at 50%.
I would like to ensure, this option would be built in from the beginning and not a later update.
I don’t know if original V, had that option?



No - it was discussed at the time, but was never implemented for the original V.

Note that my V still has 0% wear even though it’s been charged/discharged many times, but I think that is because it doesn’t report the battery wear correctly.


Can confirm.

A brand new battery capacity would be around 100-105% of the design capacity, or at worst 97% if you’re really unlucky. It’s nearly impossible to get exactly 100.0%. If all of us got 100%, then there is something wrong with the BMS


Thank you guys for the confirmation the first V did not have this feature.

I think this is VERY important to push for dev team to add it, and the reason is simple:
When device is used in desktop mode most of its life, and battery is kept at 100% charge for months, it is degrading, a battery is not supposed to stay fully charged for long period, it causes damage to its chemistry.

Is there anything else I can do to raise awareness of this feature request, other than this post?
Its not complicated to implement, and is important in devices where battery is not replaceable.


We did try for the original V but it fell on deaf ears. You can try again for the V2 but I wouldn’t hold out too much hope.

Well will see closer to shipment date… reservation could be cancelled, if price of competitors is lower/same, and alternatives are comparable in features.
It already looks like our “early bird” price, isn’t really low so will see…

How can we get attention of the developers to this issue? For a crow-sourced, focused on community development device, they seem to be hard to get a response to feature requests.
What can we do beyond this post?
