I just got a Thinkpad Yoga X1 Gen 7 and tweaked it to an almost absolute minimum. It doesn't go further than 3.5 hours (that's a maximum), in real terms it is more a 2.5-2.75h with average workload.
I have an i7-1270P, 32GB RAM, OLED 4K (switched to 1920x1200 at 35% brightness), set on "Balanced" (on "Best power efficiency" the latencies are too high...).
When using the computer normally the CPU squeezes around 6-7W of power, with bursts at 11-15-20W. The screen (35% brightness) around 5-7W and all the rest (cooling fans, speakers, all other components) around 3-4W more. If you sum and average all this you have a constant consumption of around 15W, that gives you around 3.5h of battery life for the 57Wh (at almost the minimum of its capacities:confused2:).
What kind of math gives you a 9 hour battery life ? I'm very interested...
I made the mistake to read reviews instead of doing the math for battery and real terms consumption, Never doing that again and currently planning to send this laptop to the manufacturer for a refund.
