The MAC can also turn on the low power mode to boost the battery.

The new low power model of IOS 9 is a panacea for the iphone, and the yellow battery icon looks more like a small pill, allowing the iphone to go out without the need to hang the "urine bag". Today, there are developers to take a single scratch, the MAC also launched a dose of hikes, it is endurance.

　　Carrot and stick, two-pronged

Endurance is consistent in principle with the IOS low-power mode, on the one hand, by shutting down unnecessary hardware to reduce consumption, on the other hand, to clear and suspend the background running procedures to improve performance. After opening, endurance will reduce the processor frequency, lower the brightness of the display screen, and Flash and other high-energy programs to be "special attention."

Note that endurance clears all programs that are not currently being manipulated. For two-screen users, it is likely to be in a screen code word, and on the B screen with a browser to see the reference document, but eating hotpot singing, the second screen browser is endurance shut ... Another point is that slowing down processer (reduce the speed of the processor) on the energy-saving effect, the program defaults did not open it, suggested that everyone to get the first thing is to open this option.

Endurance has three startup modes: Automatic open, open and manual, and by default it will turn on when the power is below a certain value, and if you have a high requirement for endurance, you can choose to open automatically under 90%.

　　Don't look at the ads, see the effect

Endurance is a typical procedure that does not look at the effect of advertising, because it has no effect, everything is empty talk.

I spent a whole week working on the results, the test platform for the early 2015 13-inch RMBP, purchased in July this year, the battery is in good condition, the system for the beta version of 10.11.2, the background Resident 10 balance system enhancement tools, always connect Wi-Fi, and Bluetooth connection wireless mouse, HDMI Connect the second monitor. Because I can't do it in minutes, all calculations are measured in 10 minutes for the test unit.

For the first time comparison: Use the shooter AV player, loop 1080p low bit rate MP4 format movie, uninterrupted until the battery runs out, not open endurance, the endurance of 7 hours 10 minutes, after opening, the endurance of 7 hours and 50 minutes, note that this is the CPU down frequency after the situation, but the playback process The brightness of the screen is lower, and the situation of the cotton has occurred.

The second contrast: in the company office environment, with amphetamine to keep the screen often bright, other cases of normal use of the computer, because the author's work is not high load application, so the battery has always been long, not open endurance, the endurance of 8 hours, after the opening of the endurance, the endurance of 9 Hour 10 minutes.

Third contrast: In the company office environment, start the MAC with the sleep strategy, other cases of normal use of the computer, because I am very difficult to maintain continuous work, so the computer sleep frequently, not open endurance, the endurance of 8 hours 30 points, open endurance after the endurance of 8 hours 20 points.

From the actual situation, in the case of continuous computer work, endurance can bring to the Mac for half an hour or so, for outdoor workers, this gap is likely to be "able to work all day without power" and " The difference between not working all day, and when there is plenty of electricity, such as frequent dormancy, the power boost is not obvious, and there is even a short range of endurance.

In general, endurance can bring a noticeable boost to the MAC's endurance, but not to the extent that IOS's Low-power mode is optimized, and whether you want to buy depends on how hungry you are.
