The battery life of most gaming laptops should be ok when you arent gaming. I'm sure most of us understand this. For people who want to play games but also need a laptop for work or school, the batteries should last long enough. I'm assuming most if not all of them are set up so you can run them off the intagrated graphics until you need the dedicated for gaming or whatever.
The Dell G7 15 is a mid-size gaming laptop with middle-of-the-road GTX 1060 Max-Q graphics, middling battery life, and—you guessed it—a mid-range price tag. But this system boasts a stellar feature that sets it apart from the crowd: a six-core, benchmark-crushing Core i7 processor that’ll thrill content creators. Indeed, the G7 15’s overall performance is only a step or two behind that of our current top pick among 15-inch gaming laptops, the thinner and lighter MSI GS65 Stealth Thin 8RE—and it costs about $600 less. Despite a dim screen and an occasionally too-hot chassis, this is still a worthy contender.

There are also advanced features you won't find in a regular mouse. Look for additional buttons that can be programmed for specific PC games. Many gaming mice — both optical and laser — offer multiple DPI (dots per inch) settings to control the sensitivity, and some of them even allow you to adjust the DPI on the fly, so you can switch between settings without pausing your gameplay. And not only are these models the coolest mice when it comes to their standard look, a growing number of gaming mice boast RGB lighting for customizable effects in millions of colors.
Gaming laptops can put a serious dent in your wallet, with some of the fancier models costing upward of $3,000. But who says that the right rig has to cost an arm, a leg and the soul of your firstborn? Fortunately for the fiscally conscious gamer, there are some sub-$1,000 notebooks that can run graphically taxing games like Destiny 2 and Shadow of the Tomb Raider at solid frame rates.
