Maximum number of charge cycles for macbook pro. MacBook Battery Charging Cycles

Reading time: 8 minutes

In this article, I will talk about how to know how many charging cycles your MacBook has already gone through and how much is the maximum possible charge (data table by model).

This article is suitable for all MacBook Pro and Air models released in different years. There may be some differences in architecture or description Mac versions OS.

Learn about MacBook battery charge cycles

When you use a Mac laptop, its battery goes through recharge cycles. Some recharge cycles are carried out using a full battery charge, which does not always mean one charge.

For example, one day the device could be used up to 50% charge, and then it was completely recharged. If this happened the next day, then it will not be two, but one recharge cycle. It turns out that one recharge cycle can take several days.

Ask your question to a specialist

Don’t know how to solve a problem with your gadget and need expert advice?

The battery operates for a limited number of recharge cycles, after which they exhaust their own resource. When the resource is exhausted, the battery must be replaced. It is possible to use the battery after the maximum number of recharge cycles has been used, but the battery life will be reduced.

Knowing the number of recharge cycles completed, the user can estimate the remaining number of cycles and then determine when to change the battery. To ensure optimal performance, the battery should be replaced when the maximum number of cycles has been reached.

We look at the number of MacBook charging cycles

To view the number of charge cycles for your MacBook, you can use standard means operating room Mac systems OS:

Maximum number of recharge cycles

Use the following tables to determine the number of charge cycles for your Mac battery. The battery life is considered exhausted when the number of charging cycles reaches this limitation.

For MacBook:

For MacBook Pro:

For MacBook Air:

Old Apple computers were not equipped with such “hardy” batteries as they are now. The first computers could withstand approximately 300 recharges without loss of quality.

We determine the actual capacity of the Mac battery and the number of recharge cycles through a third-party application

To obtain more information, use third party utility coconutBattery. We perform the following steps:

The coconutBattery utility has great functionality. You can use it to check the number of battery charging cycles on your iPhone.

Benefits of Apple lithium-ion batteries

Apple batteries can quickly charge up to 80% using fast charging mode, and then transfer to a slower, low-current charging mode. The time it takes to charge the battery to 80% depends on the type of gadget and its settings.

Many owners of Apple laptops eventually complain after several years of using it. This is not surprising: over time, the battery life is depleted, so after two years your MacBook Pro will no longer last 8 hours as after purchase. How can you determine when the battery (or the laptop itself) is time to change?

To find out the number of recharge cycles (this is how the “health” of the battery is determined), you need to go to the Apple menu - “About This Mac” - “System Report” - “Power Options”. Here you will find all the information you need, including battery information.




How to calculate one recharge cycle? For example, if your MacBook is fully charged and you use up 50% of the charge, then charge again to 100% and use up 50% again, that would be one cycle. Similar system allows Mac computers to last for many years - many do not exceed 300 cycles during their entire use. Let's talk about what cycle value can be considered optimal.

The maximum number of recharge cycles for your computer can be found in the table below. If for a new one this value is, for example, 1000, then the 2009 MacBook can only boast 300.

Checking periodically

I've been asked to write more educational articles about iPad and iPhone. I'm always FOR! I decided to transform the following instructions a little and instead of the standard format there will be 10 useful facts about iPhone, iPad and Mac batteries. It seems to me that in this format the information will be better settled in the minds of readers.

Fact 1. Different devices have different guaranteed number of charging cycles!

• iPhone - 500 cycles
• iPod - 400 cycles
• iPad, Apple Watch, MacBook - 1000 cycles

This is the number of cycles after which the device’s battery must have at least 80% of its original capacity. Do not confuse this with the guaranteed period, which is 1 year for all batteries.

It's funny that the iPhone claims to have twice as many cycles as the iPad. In practice, this is what happens: people change their iPhone battery much more often.

Fact 2. The charging cycle is 100% charge

The lithium-ion battery in Apple devices does not need to be fully discharged. You can charge at any time and this will not affect battery wear. Cycles must be counted at full 100% discharge. How to understand this? Will explain.

If you drain your iPhone battery from 100% to 50% for 10 days in a row, and then charge it, then you will consume a total of (100-50)*10=500% of the charge. 1 cycle is 100%. Therefore, you have spent 5 charge cycles. If you drain the battery from 100% to 0% for 5 days in a row, then you spend the same 500%, and therefore the same 5 cycles.

That is, use your phone for your pleasure and charge/recharge it at any convenient time.

Fact 3. The current battery capacity can be viewed in the Battery Life application

Here is the App Store link. Download from it, because in the search App Store you may come across fake apps with the same name.

The program is shareware. To view battery wear, the free functionality is enough. In the “Current Data” section everything is clear and understandable.

Should I change the battery based on this data? My opinion is yes, but only if you are not satisfied with how the battery holds its charge. For example, I am still satisfied with the current capacity of 2100 with the original 2915. If it was about 1000, I would run to change the battery. How much does it cost to replace a battery? Depends on the device, for example, on the website x-repair.ru, I found out that repairing an iPad Air to replace the battery will cost 3,000 rubles.

Fact 4. There are two phases of charging iDevices

The iPhone and iPad battery charges up to 80% very quickly. This is the so-called fast charging. Then the current automatically decreases and the battery is charged more slowly to 100%. This approach allows you to extend the battery life.

Fact 4. The ideal operating temperature for the iDevice is from +16 to +22 degrees

The optimal temperature for using iPhone and iPad is from 0 to +35 degrees.

Above 35 degrees, the device is dangerous to charge and is undesirable to use for a long time. If you charge at 35 degrees, the system will most likely block charging above 80% at the software level.

At high and low temperatures, the battery capacity may drop, but at low temperatures this is a temporary phenomenon, but at high temperatures the capacity drops irreversibly.

Still, try not to store your iPad and iPhone at temperatures above +35 and below 0 degrees, although Apple allows storage from -20 to +45.

Fact 5. Battery charge is affected by iOS version

It has already been experimentally proven that some versions of iOS are less energy efficient. Apple recommends that you always update your system to the latest version of iOS to improve battery performance. HA-HA-HA three times! On the contrary, if you don’t want problems with the battery, then wait until everything is updated - read reviews online from owners of the same iPhone/iPad. For example, after the release of the first iOS versions 9, iOS 11, and to a lesser extent iOS 10, there have been complaints about the battery for months.

Fact 6. The battery capacity of models in the line of devices both increases and decreases

Surprisingly, this is true. iPad 1 had a capacity of 6600 mAh. For iPad 3 and 4 maximum capacity among all models - 11560 mAh. U iPad Air- 8827 mAh. The iPad Air 2 has even less. But for absolutely all iPad models, approximately the same operating time is stated. This is due to the development of technology: the advent of the retina screen prompted engineers to greatly increase the capacity, and then more energy-efficient processors began to appear. It seems that Apple is based specifically on the operating time of the device, which should consistently deliver 10 hours during normal use on a Wi-Fi network.

Fact 7. If you remove the battery in a MacBook, the performance will drop by half

Not everyone knows this interesting fact. If the battery on your MacBook is dead and you are working from the network, then the processor speed automatically drops by half. You will feel like your MacBook is slowing down, although it will still work. Also, a System without a working battery will not allow itself to be updated. This is Apple's defense. I recommend changing the battery.

I don’t know about the iPhone and iPad (and I don’t want to know if they work on charging without a battery).

Fact 8. Modern batteries do not require calibration

For some reason, not everyone knows about this either. People buy an iPhone, iPad, Mac and start charging it to 100 percent several times in the old fashioned way and discharging it to zero. Apple device batteries released since mid-2009 do not require calibration. This must be understood and remembered.

Fact 9. It is best to store a device with a lithium-ion battery half charged

• If you store it completely discharged, the device may go into deep discharge mode and it is not a fact that you will charge it again. It will simply forget how to store charge.
• If you store it fully charged, the device may lose its capacity.

If you do not use the device for more than six months, then remember about it sometimes and charge it at least once every six months to 50%.

Fact 10. About covers and heating

Some types of cases cause the device to heat up while charging. If the battery gets very hot when charging, this is sure sign the fact that you either need to charge without a case, or change the case.

Excessive heat has a detrimental effect on battery life.

Sooner or later, for example when buying a used Macbook, we want to find out the remaining battery life. Or when selling, a potential buyer can ask you how many recharge cycles were there? Often this figure becomes decisive. All batteries, regardless of type (for example, Li-ion, Li-Po or lead-acid), have a limited number of recharge cycles and eventually simply stop working.

To find out the number of charge cycles for a Macbook battery, click on the apple-shaped icon in the upper left corner and open the “About this Mac” item, then in the window that opens, click on the “More details” button. You will see all the information about the jelly installed in your laptop, but we, on this moment, you are only interested in the “Power Options” tab. You should see approximately the same as in the picture above.

According to official information from Apple, it turns out as follows:

In any case, this information is approximate and the maximum number of charge cycles for a Macbook battery depends on how you use your laptop. Yes, not the most capricious lithium-ion battery is installed in all Macbook models, but it still needs to be monitored and periodically calibrated, because simple actions you will prolong his life.

After a certain number of charging cycles, the battery capacity decreases. This figure varies depending on the model. You can, of course, continue to use it, but the declared resource will in fact be below 70%.

MacBook laptops have a service that monitors battery health:

1. In the menu bar on the right, Option-click the battery icon.
2. The Battery Status menu opens and displays one of the following:
   • normal - the battery is in good condition;
   • a replacement is needed soon - this means that its capacity has decreased;
   • maintenance required - battery failure, MacBook can only be used on mains power;
   • replacement is required - this means that the capacity has decreased significantly and it is better to replace it.

Checking the number of cycles

Sometimes it is useful to look at the number of charging cycles completed in order to understand how much time is left before it needs to be replaced. This is necessary, for example, if you are buying a used laptop or are going to sell yours. Or you’re just planning a budget, because rechargeable batteries Apples are very expensive.

To view information about how many charging cycles have been performed, do the following:

1. Press the Option key and go to the system menu.
2. Select the "System Information" section.
3. Next, go to “Hardware”, select “Power Options”.
4. In the “Battery Information” section you can see the number of cycles (Cycle Count).

Now you need to find out how many such cycles are technically declared. This information is best obtained from the manufacturer's website https://support.apple.com, which provides a table of MacBook models and the number of battery charge cycles before it needs to be replaced.

This quantity is limited due to the battery design itself, in which it degenerates Chemical substance, therefore all batteries are classified as consumables. The only question is how long it will be able to maintain its resource, but in any case, the moment of replacement is inevitable. Modern models usually have 1000 charging cycles, but some have 500 or even 300.

How to extend battery life

• Update your MacBook software to latest versions. Battery usage really depends on what apps and how they run.
• Use the "Energy Saver" settings in your laptop's menu. Parameter " Maximum performance» leads to increased nutritional use.
• Adjust the brightness of the screen, do not use too high a brightness unnecessarily.
• Turn off Wi-Fi when you're not using it.
• Avoid using your MacBook in extreme temperature conditions. Optimal values ​​are from 10 to 35 degrees Celsius.
• Keep the battery half charged. If you store it completely discharged, it may lose its ability to hold a charge. Storing fully charged may result in loss of capacity. If you do not use it for more than 6 months, recharge it to 50% and repeat this every six months. Storage conditions should be low humidity and a temperature not exceeding 32 degrees Celsius.
