Mac tips for best use of Apple notebook batteries

As long as you pay more attention, you can increase the lifespan of the Apple laptop battery, that is, the time before the battery runs out and needs to be recharged. In addition, following these guidance messages will give you the overall effect and long-term optimization of your laptop battery.

When your battery is exhausted (meaning that the entire battery is exhausted, not just for this use), your battery time will be significantly shortened (for example, the past four hours have shrunk to less than 10 minutes). Now the sale of Apple computers, designed to comply with Apple's recommendations, even if the charge discharged 300 times, can still retain the original power reserve force of more than 80%. If your battery life is too short, you can choose to buy a new battery.

The best thing to keep in mind is that you should use your laptop at the most suitable temperature. In summer, remember not to lock your notebook in the car. The Apple laptop can be stored at temperatures of-25°c ( -13°f) to 45°c (113°F), but should be used at 10°c (50°F) to 35°c (95°F) and the best temperature is 22°c.

When you just bought a notebook:

· Get enough of your battery and be aware of the latest system software downloaded by the Software Updater program. Apple sometimes publishes system updates that can significantly improve laptop batteries.

· Your laptop needs to be used frequently, and mixed charging and off-power use. Apple does not recommend that you always plug your laptop into a charger. The ideal scenario is to use a laptop from a power source on a train and then recharge it in the office.

· If you use a desktop computer at home or in your office and do not use your laptop regularly, it is recommended that you thoroughly exhaust and fully charge the battery, which should be done at least once every month. You can add a hint message in ical. (depending on the predictive message, this hint is expected to be pre-built within the system in the Mac OS X v10.5 "Leopard", and the computer may automatically remind you of it.) )

Calibrating the battery

Regular and regular calibration of the battery will keep your battery permanently and efficiently used.

If you have a ibook, PowerBook G4, MacBook, or MacBook Pro, you can calibrate your battery by referring to the Apple's Chinese (Simplified) guide.

The steps for other Macintosh laptops are basically the same: you need to have enough battery (keep it up), then disconnect the battery and use it out of the power until the system automatically sleeps. During this time period, do not charge. After that, you need to recharge the batteries until the battery is full, and do not power down this time. After that, the battery calibration process is basically over.

Long-term preservation

If you don't have a plan to use your laptop for the next six months, Apple recommends you remove and retain a battery that is 50% full, and if you save a battery that is running out of power, the battery may fall into a "deep discharge" state so that it cannot hold any power. If you keep a fully charged battery, the battery may also be discharged, and in the future it will not be able to meet the previous charge. Be careful to keep it at the correct temperature when you are saving a battery with a charge of 50%.

Older laptops, such as the Macintosh Portable and early PowerBook 100-generation laptops, use lead acid (PB) batteries. Within 2-3 months, it should still have enough power to use a laptop computer. Within 12-18 months, the battery can still inject new power. Please note that when this type of battery is completely discharged, a chemical reaction will occur, so that the battery can be completely destroyed, the battery can no longer be used in the future because it has been unable to inject new power.

Apple's NiCad batteries used in the past should still be able to retain enough power to use laptops for 1-2 months. The NiCad battery, which is stored for 12 months, is still likely to inject new power.

Apple's previously used NiMH (Nihy) battery, like the NiCad battery, still retains enough power to use a laptop for 1-2 months. The NiMH (nihy) battery, which is stored for 12 months, can still inject new power. However, if you have a PowerBook 500 series laptop, you must use the intelligent Battery recondition software to "wake up" a battery that has been deeply discharged in storage.

Now, all of Apple's laptops use the liion battery, which retains enough power for 1-2 months to use the laptop. The Liion battery, which is stored for 12 months, can still inject new power.

Non-liion battery after 24 months, after December, the liion battery may not be able to accept the new power injection again, when this battery can be a "scrap battery." When discarding these batteries, be aware of the relevant battery handling and environmental laws in your country.

Best settings

You can improve and optimize the use of your laptop battery through a variety of system settings:

· The "Power saver" setting in the system settings, the "optimize" setting in the "battery" setting, can select "Longer battery life" and select sleep and other settings. "Sleep" setting, can put "make the computer sleep, when it is inactive time for" and "make the display water, when the computer inactive time for" The parameter setting is lower, and select the "if possible, make the hard drive into sleep" option. In options, you can select the two options to "Use this power to Si cho the brightness of the built-in monitor" and "automatically turn down the brightness of the display before the monitor goes to sleep."

· Display brightness: To further increase the battery life, the brightness of the display should be lowered. Now the Macintosh laptop in the market can be adjusted at any time by pressing the F1 (darker) and F2 (brighter) buttons. One case is on the plane: If the lights are off in the aircraft, you can choose to lower your display brightness when you watch the DVD.

· Airport Wi-Fi: An open airport wireless network consumes power even if you don't use airport to connect to a network you're using, or if you're not using it to find a wireless network that you can use. You can choose to turn it off.

· Bluetooth wireless features and other network interfaces: You can also turn off the Bluetooth feature, as well as other network interfaces that you do not need to use, such as Ethernet. They can all consume power.

· Audio: When you do not need to listen to music or other video, audio content, you can press F3 to set the computer to mute state.

· Applications and accessories: Turn off apps that you don't need to use, and disconnect devices that aren't in use. If you have a disc in your computer, you can remove it when you're not using it.

· Beware of applications: Avoid using expensive programs, such as some Microsoft applications. You can write text using the TextEdit program that comes with your system. In addition, you can choose to close unused windows.
