49Wh is very small battery for a laptop, even a light one, which this one isn't particularly. So spec-wise not impressive. Not surprising as it's competing with some pretty big players with a lot of hardware expertise.

For reference the LG Gram 15 has a 72Whr battery at 1.1kg. The current champ in 'battery size to weight ratio'. Most ultraportables have a 50-60Whr battery at around 1.3kg.
