Do batteries suffer on the Surface tablets due to heat?

[fuzzybabybunny]

I've looked at a number of Surface teardowns and all of them have the heatpipes going *over* the battery instead of having them avoid the battery altogether. The Surface Pro 4 is particularly horrendous, with the heatpipes dumping *onto* the batteries themselves. Heat is the #1 killer of Li-Ion batteries:

Has anyone had issues with battery life taking a nosedive on their Surface tablets?

The new Surface 5 will have a full-blown Core i5 with no fan. The battery life is even greater, so it leads me to think that the battery itself may be bigger as well. Seems like an even worse case for heat-induced battery death, no?

I'm thinking about getting the upcoming Surface 5. Reviews say that the stylus latency is the first time where it is actually un-noticable. With battery life comparable to an Android tablet but with full PC functionality and the inclusion of 3G/LTE support, it seems like a killer tablet, but the internal design choices of the previous generations really give me pause. Everything is glued together, the battery is very difficult to replace, the battery sits right below a heat sink, and all components are integrated, meaning no option to upgrade RAM or SSD.

I have a surface pro 3. Can't remember how long I've had it, but I got it a couple months before the surface pro 4 was announced so at least a couple years.

I haven't noticed any major battery life issues. Every once in a while I'll have an odd thing happen where I get the 10% battery warning, than the critical warning, then the thing shuts off all before I could even plug it in. That's not consistent though, other times it'll take some time before the first warning and the 2nd warning. Nothing abnormal IMO

I think the Surface Pro 3 is different. When I look at the teardown photos the heat pipes are no where near the battery, so that's good.
