In use battery life is largely the same, though Intel has added some additional features with 12th Gen Intel Core that can improve in-use power consumption in some scenarios. The main optimizations we were able to land were in standby power consumption. For Windows users, this means longer Modern Standby before going into Hibernate. For Linux, more importantly since hibernate is atypical, it means being able to leave your laptop unplugged for much longer when not in use.

Better standby performance is great news, as I know it's not all Framework's fault for the inconsistent standby power drain on the current models.

The standby performance was what kept me from buying a previous gen frame.work despite loving the mission and wanting to support y'all. I was holding my time until either the efficiency cores came along (if that has any improvement in standby? I'm not even sure) or if you ended up making AMD where I believe S3 sleep states still exist.

Very exciting to hear there's an improvement in this generation. Is that improvement due to intel changes, or due to frame.work changes? Can you quantify the standby improvement for linux in watts or battery % / 24h?

Does battery life significantly change between processor models?

Congrats on the refresh launch!

This is a combination of hardware and firmware improvements by both Intel on 12th Gen Intel Core generally and us on the Framework Laptop specifically. This is with s0ix standby, and we see ~0.4%/hour typically in Fedora 36 on 5.17.6 with the settings in our setup guide: .https://guides.frame.work/Guide/Fedora+36+Installation+on+th...

Thanks! How about ubuntu/debian?

For reference, on a Intel 11th Gen Lakefield (Lenovo X1 Fold), using a Vanilla Windows 11 Pro with the non-Lenovo Intel GPU driver downloaded from Intel Driver & Support Assistant, given the results of powercfg /sleepstudy I get a 6% of drain for 9h54 min (so about 10h) therefore 0.6%/hour in "disconnected" (no wifi activity) S0ix standby.

Before, with the official Lenovo driver, it was 0.5%/h (4h: 2% drain). I was hoping to get better results, but this isn't so bad with about 0 optimization!

S0ix has gone a long way, in both Linux and Windows.
