Yep. We should mention here improvements within the last decade? The X13 Gen3 (AMD) also should allow run theoretically 17 hours[1]. I think a peak was reached with the MacBook (Polycarbonate Body) or T430s which allowed to replace the battery at the device bottom with a coin, easy maintenance and sturdy frame. And good balance because the weight counteracted the open display. With "peak" I mean the situation that a thing reached a point where it was actually good and then get impaired. Sometimes because another feature was added but didn't fit. Or just for the sake of change. The seven vs. six row keyboard layout is such a thing. The 16:9 screens where everyone immediately wanted the 16:10 back (happening right now). The MiniSD-Slots replacing the SD-Slots...

How does one achieve 17 hours of battery life with an X13 Gen3 AMD? I can manage maybe 6.

  Do you have a discrete GPU? Disable it. Run TLP and powertop to see what uses too much power and to adjust tweakables.

    I do not have a discrete GPU, have run TLP and Powertop and have adjusted the tweakables. Maybe it's my 1440p display.

      If you use zenmonitor, what is the package power on a typical workload? It should be 2-3W maximum normally. If it's too high, it's a too common case of manufacturers setting insane tweakables, and can be remediated using amdctl/ryzenadj/zenstates (or in some BIOSes using the PBO2 setting). Otherwise, it can sometimes be a bad SSD using a lot of power.

        I'll try those out, thank you for the tips.

The big problem with newer AMD ThinkPads from what I've heard is use of some second-rate (mostly Realtek) components in places, which in comparison to those used on Intel models don't perform as well and are more likely to cause trouble under Linux.

  I just swapped the realtek wifi of my P14s amd gen 2 with Intel ax210. Cost was around 10€. I think since around one year ago upstream kernels do support the realtek wifi card properly.

  Actually they use four different. You can swap them yourself (15 - 20 EUR): * Qualcomm (Atheros) -> GOOD (or even best?) * Intel -> GOOD * Realtek -> It works okay for average users * MediaTek -> Bad or lack of reputation The X13 is currently shipped with Qualcomm. Older T14 seem to use mostly Intel. On a P14 Lenovo we got a MediaTek (no reliable after Resume from Suspend) replaced by Realtek. I would be happy if AMD and Qualcomm team up together again. The questionable ARM-Deal with Microsoft also didn't worked out well for Qualcomm.
