> Both phones can run fairly hot. I think given how I hold the phone (closer to the base of the phone) I tend to notice the Librem 5 more often than I notice the Pinephone getting hotter. This is mostly because the frame / chassis for the Librem 5 is metal, and conducts the heat around the sides of the phone. So you’ll notice it getting hot after you’ve used your phone for a good bit.
Power management is complex these days. You'll often get a minimal implementation from the chip vendor, and it is a fair amount of work to really polish the lower level support. On top of that, you have to integrate this with the rest of the OS, so that active apps can increase the clocks, which then get automatically scaled back as system load decreases. So there's a lot to do on the userspace side as well.
- Valkhyr 6y agoThis is the major reason I deferred my Evergreen Librem 5 order for the Fir batch (set to ship in ~1 year), which will (a) have a smaller process size (14nm vs 28nm currently) and (b) allow for more time for optimizations.
- fsflover 6y agoFir batch will probably have its own disadvantages: https://source.puri.sm/Librem5/community-wiki/-/wikis/Frequently-Asked-Questions#71-what-will-be-the-changes-in-the-fir-batch-and-should-i-wait-for-it https://source.puri.sm/Librem5/community-wiki/-/wikis/Freque....
- Valkhyr 6y agoThank you for that link - I had not seen that - my impression was that Fir would be a die shrink and otherwise identical. Reading through the explanation, I think the tradeoff is still worth it for me since I care more about battery life and heat than full convergence (I plan to use this device as a portable Linux machine on the go, not so much (if at all) docked). I do think Purism should have been clearer about this though.
