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 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 looks like this:

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 by performing simple actions you will extend its life.

Currently, smartphones and tablets use lithium-based batteries and lithium-polymer batteries.

Each of them has its own resource, which depends on the correct charging and operating conditions. There is also the concept of a “charging cycle” - today we will find out what it is.

What is a charging cycle?

The charging cycle is a set of processes associated with filling the battery with energy and completely discharging it. Their number determines how many times the battery can be charged and discharged.

Accurate data on the number of cycles for lithium batteries no, as these figures may vary depending on correct use. On average, the resource of such batteries is 600-800 pieces. This figure may seem small to some, but if we assume daily charging and discharging, then 800 cycles - 800 days, that is, more than two years.

How many charge cycles are left?

Let’s imagine a situation where within two days the phone was discharged by 50% both times and was required to be charged to 100%. In this case, 1 charge cycle was used. Such moments can be repeated regularly, which leads to slower depletion of cycles and extends battery life. For this reason, many experts recommend not waiting for your smartphone to be deeply discharged and charging it regularly.

There is a relationship between the remaining energy in the battery and the number of cycles. Remaining charge level, % - remaining number of cycles:

• 90 - 4700.
• 75 - 2500.
• 50 - 1500.
• 0 - 500.

The table shows that if you discharge your smartphone by 50% every day, the number of charge cycles will be about 1500.

What's the best way to charge your smartphone?

It is important to understand that you cannot keep a fully charged smartphone constantly connected to a charger, for example. No, overcharging will not occur, since the charging controller will stop the flow of current, but a constant drop in the energy reserve to 99% and the subsequent replenishment to 100% will lead to a decrease in the number of charge cycles.

Recharging the battery, which occurs under the control of the user, has proven itself best. As soon as 90-100% is reached, you need to disconnect the gadget from the network. Of course, in everyday life it is difficult to ensure ideal battery operating conditions, but we must try to follow.

The following factors influence the reduction in the number of possible battery charge cycles and the reduction in its capacity:

• battery overheating;
• regular depletion of charge to 0%;
• use of non-original charger ().

Even if you manage to extend the life of the battery by 2-3 years, the natural aging of its constituent elements will still lead to a decrease in capacity by 15-20%.

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?

Battery is functioning limited quantity 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 system MacOS:

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 extended information, you should use the 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 the fast charging, and then switched to a slower recharging mode with a low current. The time it takes to charge the battery to 80% depends on the type of gadget and its settings.

The battery of any device is designed for a certain number of recharge cycles, so every MacBook owner will sooner or later be faced with the need to replace this important part of the device. Of course, such a replacement will require some financial investment, so it is always useful to know how depleted the battery life is in order to be prepared when replacing the MacBook battery.

You can find out about the battery status by going to the menu “About this Mac” - “More details” - “System report”. Here you need to select a section “Power supply” - “Battery information”.

We found out how many recharge cycles the MacBook battery has gone through, but how can we find out how long the battery can last? Since our goal is to figure out when the MacBook battery will need to be replaced, we can't do without this information. Depending on the laptop model and year of manufacture, the device may be equipped with rechargeable batteries With different characteristics. This information is not secret and Apple makes it available to its users:

Now, knowing the “mileage” of our battery and the number of recharge cycles given to it by the manufacturer, you can find out when you need to replace the MacBook battery and be prepared for this in advance. Despite the data provided by Apple, do not forget that MacBook battery life is highly dependent on operating conditions. There are several ways

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 serve for many years - many do not accumulate more than 300 cycles during the entire period of 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.
