I figured two hours was all you could expect to get out of a gaming laptop, but since I wanted more battery for long flights, I decided to test the impact of changing the Turbo Boost parameters to see what would happen. Video playback was a bit better, but the laptop has a GTX 1060 in it, and GPU-equipped machines always use more power. When new, it got roughly two hours of battery life in normal use.

This expands the warranty to cover damage caused to the CPU by overclocking ( read more in the FAQ).Here’s where I want to pivot and talk about my own experience with this trick. For added peace of mind, Intel now sells performance tuning protection plans for each of the supported processors, priced at $19.99. The tool itself is free and can be downloaded from here. So at least for that board (and probably others), you'd need to uninstall the utility to take back manual control of voltages, multipliers, and so forth. Tanous also noted that Intel's utility ignored changes made in his motherboard's BIOS (Gigabyte Z390 Aorus Master). Not surprisingly, Tanous found that better results can still be had by manually overclocking through the BIOS, though the gap in performance was not enormous in his testing. We have not had a chance to test it yet, but Jim Tanous at PCPerspective did. Intel describes its new tool as a 'hyper-intelligent' utility that sets parameters 'based upon individual performance potential.' Your mileage will vary, of course.

This new utility is different, in that it's supposed to automatically overclock your CPU.
