About a month ago, I bought a brand new dell Inspiron 15 7570 with Core i7 8th Gen processor. From the first day, it on a 100% complete charge it runs for hardly 2 hours. I use it with lowest brightness and complete black them. I am talking about only internet surfing with 5-6 tabs open.
Please help me find the issue, is this its default battery life? Or there is any kind of hardware issue? 😞
(See how I am using it to extend its battery timing)
