I upgraded to the AMD board and the larger batteries and this improved significantly - 7/8 hours of real usage now, which for me is fine. On linux with minor tweaking. Depends what you need, but surely for most people a full workday without power is manageable!
Are those numbers with power saver mode turned on? For what this laptop is being used for I don’t need much muscle and would rather need to charge less frequently.
No, normal usage with no special power saver options. Turning off WiFi+minimal brightness+power saving etc pushes it further, but I'm rarely in a scenario where I want to do that for more than a couple of hours anyway.
I've heard Windows defaults or more advanced Linux games can do better, but at this stage I don't feel the need.
