From a technical point of view, ordinary consumers naturally desire new products to surpass the previous generation in all directions. Not all new products, however, are perfect, and the Surface Pro 7, which was released recently, has a poor battery life, far below expectations.
On the Reddit community, one user wrote
Do we know WHY Surface Pro 7 battery life is worse than 6?
CPU and RAM consume more energy and have little change in other configurations. The Surface Pro 7 should be the same or even better, but the actual range is only five or six hours. What’s the reason? My understanding may be that after the IRIS GPU is enabled, it is the GPU task that causes the increase in battery life. However, even under normal use, there is also user feedback that the battery life significantly shortened.
Another user complained
So I got Surface Pro 7 today and I used it to set everything up and just browse the internet for a while and watch a few videos on Youtube. To my surprise, the battery only lasted for about 5 hours… Which is a huge let down because one of the major reasons I got it was for the portability factor and the battery life.
Microsoft actually released a firmware update about a month ago to resolve the issue, as the Surface Firmware 184.108.40.206 update log reads:
Help improve battery life
Obviously, the issue has not been resolved, and some users on Microsoft Answers have even attributed the problem to recent cumulative updates. Microsoft claims the laptop can provide 10.5 hours of mixed use, but media reviews and the average consumer say it’s hard to last more than six hours.
