Moderate to heavy use. Not 100% heavy use. The official specs claim 15-18 hours battery life. Practically, I'd say I do about 8 hours a day and the Mac lasts a couple of days before the battery goes to single-digit percentages. With lighter use, I see nearly a week of battery life.

[Mine is an M2 16-inch MBP from last year, perhaps the M3's are somewhat better?]

In comparison, my new Dell work laptop with an Intel chip gives me about 4 hours. It's not an apples <-> apples comparison but they're in the ballpark.

Same here. Disconnected the charger when moving stuff in the office, worked a full day and halfway through the next one the laptop started complaining.

It's impressive. Nothing on the market comes even close.
