My Yoga had a change of battery in warrenty time (after 3 years) due to a defect on the mainboard. After installation of the new battery, it took quite a certain time, till the battery was found and recharged. After recalibration I tested the new battery with the Lenovo Vantage tool, and it showed a quite good looking capactiy of the cell but a manufacturing date older than the Yoga (more than 3 years). While using the computer it seems as if the battery is worse than my 3 years old former battery. This one was able to last for 5 to 6 hours in normal use. The new one is more like 2 to 3 hours.
Is it possible, that the battery was deep-discharged and the Lenovo Vantage tool did not get the right capacity? Is it normal, that a 3 year old battery is installed for a warranty battery replacement?
Thanks for help!

Hi Hagma! Where did you buy the battery? Did you follow the correct part number for your battery here: https://download.lenovo.com/parts/ThinkPad/x260_yoga_frubom_20151221.pdf? Try power cycle by holding down the power button for 10-15 seconds while the laptop is unplugged from the outlet.

Thanks for your suggestions!
The battery was installed by a swiss repair center, on behalf of Lenovo. I hope, that the right one was installed. It‘s a 00HW026 with production date 10/07/2015 and first use 04/12/2019.
I started already a recalibration of the battery.
The values in the powercfg /batteryreport show times of nearly 4h and a capacity of 42.8 instead if 44, but the yoga is new installed, and the history is quite week.
Before this new installation and battery replacement, the 3 years old battery lasted nesrly a whole working day. This is far away now.
The Lenovo Vantage tool shows a capacity if 45.34 Wh instead of 44Wh design capacity....
this seem to be a little bit strange....
What shall happen when I power cycle the Yoga??? What‘s the meaning of this?
