There’s a number of benefits to long battery life besides being able to work for long stretches unplugged.
- Longer cycles means cycle count accruement and thus degradation is slower (sometimes dramatically so)
- For longer trips, charging can be done overnight with a tiny trickle-charging phone brick, which is also better for battery health
- No need to bring a brick, cable, or power bank for shorter trips
- Impact of phantom drain during standby is greatly mitigated
- Laptop will more often than not have enough charge to be used whenever you pick it up, without having to leave it plugged in all the time
- Bluetooth and wifi can be used liberally without fear of chewing through battery too quickly
- You as a user spend a lot less time thinking about your laptop’s battery
There’s also secondary effects, like a machine being efficient enough to have long battery life generally also reducing its heat output and making it more practical to keep cool with a slow fan or passive heatsink.
