T550 battery

I have 2 batteries in my laptop. Battery lifeteime at Windows 7 was 10-13 h after system start. Windows battery gauge indicated 2 batteris  On the same day I have updated BIOS to 1.14 and upgraded system to Windows 10. Now Battery lifetime is 5 h. W10 battery gauge shows 1 battery only.  Lenovo Companions shows 2 batteries and also lifetime of 5 h. Any ideas?

And we're back...
