Framework Laptop 13 Pro redefines upgradeable Linux laptops with a bigger battery and premium chassis

Phoronix’s review of the Framework Laptop 13 Pro highlights a redesigned, upgradeable chassis (6063 aluminum, 1.4 kg), larger 74Wh battery, LPCAMM2 memory up to 64GB, and cross-generation component compatibility. Paired with the Panther Lake platform, Linux out-of-the-box support is strong across Ubuntu 26.04 LTS, Fedora, and Arch, with promising runtime improvements and a claimed up-to-20-hour battery life; a quirk with non-official 150W USB-C chargers can throttle performance until using the official Framework charger. Overall, the 13 Pro stands as a top modular Linux laptop option.
