Move the slider bars for Computer Sleep and Display Sleep as far left as you believe is comfortable. You probably don’t want your computer going to sleep after just one minute but don’t want to leave it on indefinitely either.
4. Quit runaway applications.
Occasionally, an app will consume an inordinate amount of system resources even when not in use. Not only does this impact your notebook’s performance, but it also seriously degrades battery life.
While it’s a great feature, the backlit keyboard on Macs can shave precious minutes off your runtime.Time Machine makes it very easy to back up all the data on your Mac, but copying that data to another drive consumes system resources. Fortunately, you can turn off Time Machine while your laptop is running on battery power.
Believe it or not, private browsing will let you squeeze out a bit more battery life, because the browser is no longer accessing the hard drive to cache pages and images. Of course, Safari won’t remember your search history or autofill forms, so you have to balance its convenience with the potential battery savings.
Apple’s Spotlight, which instantly returns search results of everything on your hard drive, is very useful. But the way it works consumes CPU resources. You can prevent Spotlight from searching your drive.
MacBook Pros have both integrated and discrete GPUs and can switch between the two seamlessly, so you can get better battery life or increased performance, depending on the task. However, the discrete GPU can seriously cut into battery life.On MacBook Pros from 2008 to 2009—those with Nvidia GeForce 9400M and 9600M GPUs—Select Better Battery Life in the Energy Saver control panel.

10. Eject optical disks if you’re not using them/disconnect unused peripherals.
Even when not in use, whenever you have an optical disk in your notebook, the system will occasionally spin up the drive (and the laser) to check the disk. While this isn’t an issue for MacBook Airs, which lack optical drives, you can save battery life by disconnecting any peripherals, such as external hard drives and mice. These devices don’t draw a ton of power, but every little bit helps.
HP's Envy 13t proves that you don't have to break the bank to get a lightweight laptop with heavy doses of style and performance. For under $800 ($749 as of this writing), this 2.9-pound ultrabook packs the power of an Intel 8th Gen Core processor, the sexiness of an all-metal chassis and the convenience of all-day battery life. It also has one of the best keyboards on the market. Higher-priced competitors offer more vibrant displays and even longer endurance, but verall the Envy 13t is a fantastic value, especially for college students on a tight budget.
Update May 28: HP's announced the 2019 Envy 13, which improves the 2018 model with a privacy camera kill switch and a fingerprint reader.
We see so many silver laptops in our lab that it can be hard to tell them apart, but the Envy 13 adds some original touches that make it stand out. The matte aluminum lid has a small incline in the back that covers the hinge, giving it clean, sleek lines. The shiny HP logo in the middle of the lid really pops while the tapered shape of the chassis makes the entire system look slim and sexy. A smooth bottom surface is made from magnesium alloy.
Opening the lid reveals an attractive aluminum deck, completely with silver keys that match the aesthetic (MacBooks break the color scheme by using brown keys). The side bezels around the 13.3-inch screen are relatively thin, but no one would mistake this display for one of the nearly edgeless offerings on Dell's XPS 13 or Lenovo's Yoga C930. HP also offers the Envy 13t in a "Silk Gold" color.
At 12 x 8.5 x 0.55 inches, the Envy is slim enough to fit into a narrow pocket in your bag and compact enough to fit on even the narrowest seat-back tray while its 2.93-pound weight makes it very easy to take with you. The Dell XPS 13 and Microsoft Surface Laptop 2 are both lighter (about 2.7 pounds), as is the latest MacBook Air (2.75 pounds).
For a notebook this thin, the Envy 13t has a fair selection of ports, which includes two standard USB 3.0 connections and two USB-C ports, with one of each on either side. There's also a 3.5mm audio jack and a microSD card slot. The USB-C ports can be used for charging, data and video out, but you they can only accept power from an HP branded charger. The device itself comes with a proprietary, non-USB charger.
The 13.3-inch,1080p touch screen on the Envy 13t offers decent image quality. When I watched a trailer for Thor: Ragnarok, colors like the green in Hela's cape, the purple on a statue and the red behind the Marvel logo all seemed fairly accurate but they didn't "pop" like they do on pricier competitors like the Dell XPS 13 and HP's own Spectre 13. HP also offers the Envy 13t with an optional 4K display, which may be brighter and more vibrant (we haven't tested one).
According to our colorimeter, the Envy's screen reproduced a solid 106 percent of the sRGB color gamut. The MacBook Air scored a slightly higher 109 percent, and the XPS 13 fared even better (130 percent at 1080p, 117 percent at 4K). The Surface Laptop 2 is in a class of its own at 176 percent.
The glossy surface on the panel, along with below-average brightness hurts the viewing angles on the Envy. Even from just 45 degrees to the left or right, colors started to fade and the overhead lights in my office reflected back at me. The screen measured a modest 248 nits on our light meter, which is below the 317 percent premium laptop average.
