Hi 

I am using Dell E5550 Latitude laptop. Problem is When I charge the battery to 100%, & after it is full charged I disconnect the charger from the power socket. So It operate on battery, the total backup time on battery is around 60-70 minutes, although I set the power scheme on battery saver mode. But it only gives 70% maximum backup time. 

This poor battery performance is delaying my work, which is related to 5g intergration, I am unable to deliver projects on time as well.

Attaching screenshot as well!

Please give me a solution for this problem!
