Battery usage after update from 6.72 beta to 7.10

Hi,

I have now Version 7.1 since a couple of days and have the feeling that my battery % is going down more quickly than with the last beta 6.72.

I have not seen this using the last 3 or 4 6.xy beta updates, the battery % was always very simelar.

Is there any "recalibration" of the battery neccessary after a major firmware update?

Best regards,
