Hi there, the Lenovo Yoga C940 14" laptop model # 81Q9002GUS features a battery life of up to 15 hours.If you are getting substantially less battery life, please adjust your screen brightness settings. A setting of 100% brightness will drain your battery much faster than a lower setting. We recommend setting the screen brightness to some value below 100% that is still comfortable for you to view. Next be sure Battery conservation Mode is turned off. This power management setting should only be used when the laptop is plugged in all the time. It will prolong overall battery life by only charging the battery to 60-percent of capacity. Here is a link to instructions for turning off Battery Conservation Mode: https://support.lenovo.com/us/en/solutions/ht103159. Also check what programs are running in the background on the computer. Be sure only the programs you want running in the background are. These programs will drain the battery.
