Hello!
Few weeks ago I bought used Fujitsu Lifebook S935 with new battery (model FMVNBP229)/ I noticed a suspicious short battery life - with full charge Windows 10 shows me a remaining time approximately 2hrs 15mins with low-energy consumption plan on (while specifications say about at least 10 hrs of work). The wear level of battery is 26%, it means that only 17831 mWh from designed 24300 mWh is available. But even with this wear level my battery must keep at even 6-7 hours. Has anyone encountered this problem? Thank you.
