List of Laptop Battery Life
This list shows the battery life for all of the different laptops that I’ve tested. I also explain how I perform laptop battery testing.
How I Test Laptop Battery Life
- The laptop battery always starts with a full 100% charge.
- All testing is done with the screen set to 50% brightness, as I do not normalize this to any specific value in nits this is a potential cause of variance depending on the output of the panel.
- By default, Windows will hibernate the laptop at 5% battery charge left. I attempt to lower this to 1%. If this is not possible I pause the timer once it shuts off, turn the machine back on and continue timing.
- The test is started by removing the power cable and starting a stopwatch simultaneously, the machine is monitored until the battery runs out.
Gaming
- I test by running The Witcher 3 at 1080p medium settings. The test is reproducible as I leave it sitting in the same section of the game.
- By default Nvidia battery boost caps game frame rate to 30 FPS, I use this default.
- If a result in the table below is listed as 0, means the laptop does not have discrete graphics and the test was not attempted, or that the frame rate was not good enough for a playable experience.
- Gaming on battery isn’t recommended if it can be avoided, as discussed here.
YouTube Playback
- I run the same 6 hour 720p video on loop in cinema mode using Google Chrome.
- I test with the lowest power profile available through what ever software the vendor offers.
You can click the heading titles to sort the data from lowest to highest or by either type of test. Values are in minutes, higher is better.
