So what do those values of 48868 and 48944 truly mean? May be more related to marketing than technical performance. Read the fine print.....
I would expect that the "48" prefix could be a voltage reference. Then the 944 and 868 would be some sliding scale indicating battery power status.
Design capacity is one thing. Actually being able to reach that capacity is another. Many such things have some plus or minus tolerances.
Make and model laptop?
Specs?
Do you have the laptop's User Guide/Manual?
If so, check the battery related sections and refer to any troubleshooting procedures therein.
No need to immediately do some "fix". First try to discover if there is indeed a problem, what that problem may be, and then determine possible solutions.
