There’s a Low Power Mode to extend runtime; Series 11 also supports faster charging than earlier models (manufacturer figures indicate ~80% in ~30 minutes under ideal conditions). Actual battery life depends on usage, settings, and model (cellular use reduces runtime).

Will my old Apple Watch bands work with Series 11?

Yes — most Apple Watch bands are interchangeable as long as they match the case size (42 mm bands fit 42 mm case; 46 mm bands fit 46 mm case). Verify band compatibility if Apple changes attachment dimensions for future models.
