X1Y3 battery wear level

After just 20 charge cycles(I have just run reset) does 8% wear seem excessive in 4 months?

Re: X1Y3 battery wear level

That does seem a bit high. My X1Y3 is ten months old and is reporting 9% wear. That's relative to the design capacity, but my battery started a bit higher, so it's more like 11% loss of capacity in 10 months. So I'm getting about 1% loss per month, and you have 2% loss per month. That's a lot.  

 

I do find that these numbers fluctuate a bit from time to time, so maybe keep an eye on it for a bit. I've seen swings as large as 4% for some reason.  I went a bit overboard and ran the Windows Battery Report, and used the data to plot the capacity of my battery over time. Note the big fluctuations and the fact that these batteries can start well above design capacity.

My TP25 has less than 1% wear now in a year BUT on that laptop even though its less than 1% the external battery will go from 15% to 1% in 1 minute so I think a cell is going bad.  Vantage still shows "good" though.
