Tools like that to manually adjust battery percentage stuff are usually made by the manufacturer for their computers like Sony's tools in that post and Lenovo's power manager for their ThinkPads.
Microsoft doesn't have that for their Surfaces. Although batteries are still managed smartly in any modern device and those tools are more rare than not.
Well here's what I have to say about your situation.
1. Batteries go south and age all the time. Your laptop's battery may have had some underlying issues contributing to its demise, you may just have had bad luck, etc.
2. Replacement batteries are a thing and if the VAIO had a removable one like most less-new ones, you can remove the battery when plugged into A/C for a while. (which I recommend) Could probably buy a spare too.
3. What I'm really worried about is that the Surface's are notoriously hard to repair. When, not if, your 3's battery wears out whether by heat, usage, age, or any other combination it will be very difficult, if not downright impossible or impractical to replace. (and if you don't want to DIY, it'll be expensive.)
