Batteries within laptops are consumable items, they degrade in capability during usage.  The battery display programs periodically check how much charge the battery can store and from time to time update that feature for calculating the % remaining number.  As time passes, often the battery display becomes out of calibration from the actual.


To reset this calibration, simply charge the battery to 100%.  Disconnect the AC adapter and allow battery to discharge, all the way until the computer turns itself off.   Then recharge to 100% in one session.  Sometimes repeating this again will help bring the software display closer to actual performance.


The Lenovo Vantage maintenance program has advanced features for battery analysis and additional charge - discharge parameters compared to Windows.  IF Vantage is not already installed, search for it within Microsoft store.


Your system hardware manual has the detailed procedures for accessing the battery.  You can access the manual and other important information for your system by clicking on the word "SUPPORT" at the top of this page, then entering you system serial number.
