As you would expect, AMD claims that its Ryzen 6000 chips have better performance, performance-per-watt, and battery life than Intel's Alder Lake. AMD claims 24 hours of battery life, but it is notable that AMD and Intel use very different methodologies for battery life claims — AMD tests in airplane mode with the panel brightness tuned to 100 nits while playing video only. Intel claims it could match that 24-hour rating under the same conditions, but doesn't measure under the same conditions because it doesn't think it's applicable to most users.

That depends a lot, I'm divided here. On one side, AMD is right, as it isolates their processor and system, and should show how much the CPU and GPU consume alone. On the other hand, I believe most users would use an unplugged notebook with some sort of internet connection. But even then, it's fair to expect a lower brightness setting in this situation. I think Intel is just running from the fight, if they insist on letting other parts of the system to use a lot of energy to make their numbers look less bad.

Well, better to wait for independent reviews anyway.

Honestly CPU vendor measures (AMD and Intel) of battery life are pretty irrelevant. If you are building your own box from components then there are reviews that isolate the CPU if you are really interested in power \ performance ratios, but with a laptop it's impossible to isolate the CPU from the motherboard / chipset / display / memory and so on.

You might get a general idea for how a laptop with X CPU will perform and how long its battery life will be, but in the real world all those other factors will come into play. I would always compare laptop vs laptop, not laptop cpu vs laptop cpu.

Well, sure but when comparing and buying laptops the CPU is usually the first thing to consider as it determines not only the general use case (everyday, gaming etc) but also other features (connectivity etc).

As expected, the max power draw for boost is very high @ 64W, when we consider the fact that most of these CPUs have a 15W TDP. That is 4x higher to obtain the boost clockspeed. In real life usage, I think the battery life under light usage will decent because I suspect Intel will offload most if not all the work to the E-cores. But when you are gaming or loading the system where the P-core wakes up, then I believe battery life will take a hit when compared to Ryzen 6000 series. Otherwise, I expect heavy throttling due to heat and/or power limit.

Not really. For many the display quality, keyboard, and trackpad are far more important than if their Excel spreadsheet recalculates in 3.2s instead of 3.4s. Battery life is actually the #1 thing that users used to say, though I think that distinction is becoming less in the thin and light area (once you go over 10-11 hours, it's not as important IMO). If you actually use a laptop for work, you'd know this.
