Log says that the original cpaacity is 45 000 mWh while the current one is just 34 710 mWh. Also I there has been 1687 battery cycles. I am unsure how quickly it changed the capacity as I had to reinstall Windows few days ago but it slightly concerns me. My laptop model is Lenovo ideapad l340 15irh with the original battery.
Standard metric is above 80% capacity after 1000 cycles. Yours is above 77% capacity after 1700 cycles, that’s good. Is you want to make the battery last longer : don’t charge above 80%, don’t discharge below 20%. There might be settings in your BIOS or OS to do that.
