Which is better for battery life?

The Samsung. LG rates the gram Book at 10 hours and Samsung rates the Galaxy Book5 at 19 hours, so the Samsung lasts close to twice as long away from an outlet.

Is the LG gram Book fast enough for everyday work?

Yes. The Core Ultra 5 115U with 16GB RAM handles browsing, Office, video calls and light photo editing. The Samsung's Core Ultra 7 is quicker on sustained heavy loads, but most shoppers will not notice the gap day to day.

Do I lose anything by picking the cheaper LG?

You give up the touchscreen's opposite: the LG has one and the Samsung does not. You also give up about 9 hours of battery, the fingerprint reader and the Ethernet port. You gain a touchscreen and save about $200.

The Samsung, at about 3.5 lb against 3.7 lb for the LG. The difference is small enough that most people will not feel it in a bag.

Is the Samsung worth the extra $200?

If you work unplugged all day or run demanding apps, yes, for the battery and the Core Ultra 7. If the laptop mostly stays on a desk, the LG's touchscreen and lower price are the better trade.

Can I add more storage to either?

The LG lists two M.2 slots, so you can add a second SSD. The Samsung lists a single 512GB drive with no second slot, so plan on external storage if you need more.
