I recieved my new HP envy 2019 - i5, 8gb ram, mx 250 gpu, touchscreen, 1080p model last night. I downloaded the programs I need for my uni work onto it, and despite reading reviews on the laptop being able to last 10+ hours, I only got a couple out of it. I charged it up whilst I went to work this morning thinking that it might need a full charge first and by the time I came to use it (at 100% battery) it only said it would last 3 and a half hours. Am i doing something wrong? Could someone help me please? Im not sure I have given all the details you may need but I can give more details upon request.
