X201 6 cells battery

[sbux4622]

I have a 42T4835 6 cells battery come with my new x201. The battery has been fully charged for several times from 10% to 100%. The battery self-discharges 4% (fully charged) in about 10 hours after switching machine off and disconnecting from mains. Fingerprint scanner is also off. The self-discharge rate is a bit quick to me.

I used to have ThinkPad 570 ten years ago. The battery got a similar issue. IBM changed a new one for me but did not help. I accepted that was normal. The problem does not happen on my ThinkPad 600,T41 & T43.

Is that normal for x201?

Thanks.
