As a last resort, re-installing Mac OS X 10.2.x from a CD that has a later release (like Mac OS X 10.2.3 or 10.2.4) seems to alleviate these issues for some readers. When a MacBook is plugged into a power outlet, and the battery is fully charged, the battery is bypassed, and the MacBook will be using power directly from the power adapter. However, charging the battery in temperature higher than 95° F (35° C) can permanently damage battery capacity.

Batteries in our devices are getting better day by day. Apple products always have been famous for the ability to hold their charge longer than their competitors and MacBooks are not exceptions. You can work up to 10 hours on average MacBook until it fully discharges. But is it a good idea in general?

Should you drain your MacBook battery before recharging? Apple does not recommend fully draining MacBook batteries because if a battery is fully discharged, the battery could fall into a deep discharge state. When the battery falls into this state it may stop being able to hold any charge.

There are 2 different things we want to discuss here: battery life and battery lifespan. Battery life refers to the amount of time that left until your laptop will lose its current charge and you will need to recharge it again.

Lifespan, however, refers to the longevity of your battery, the time after which you will need to replace the battery. In this article, we'll discuss how to maximize both.

While we all want to keep things working as long as possible it is important to understand that losing battery does not mean losing the laptop. In the worst case, the battery can be replaced, and the cost of the replacement compared to the cost of the new MacBook is high, but not outrageous.

How Much Does It Cost to Replace MacBook Battery?

If your MacBook is under warranty, then there is no charge for you. If not, then following is a table of fees for battery replacement according to Apple:

How to Check Battery Condition on MacBook

MacBook provides information about the health of the battery. Time to kill corona (2020) by agabascal & marcolbx mac os. In order to get this information do the following:

1. Press Option (Alt) key on the keyboard
2. Now click with the mouse or trackpad on the Apple logon in the top left corner of the screen. This will bring down the Apple menu.
3. The first item in the drop-down menu is System Information. Click on it.
4. Scroll down to a line called Power and click on it.

There are several interesting things you can find here:

• Full charge capacity (mAh): the capacity of the battery when it is fully charged.
• Charge remaining (mAh): how much charge is left until the battery fully discharges. To find out how much charge does your laptop has currently you can divide Charge remaining by Full Charge Capacity and multiply by 100. For instance, on the pic below the current charge is 4490/6261*100 = 72%.
• Cycle count: how many times the battery has been fully discharged. Apple uses an interesting method calculating it, see the explanation below.
• Condition: health condition of the battery, see details below.

MacBook Battery Conditions

The battery can be in one of 4 possible conditions: Weed topia mac os.

• Normal: The battery is functioning normally.
• Replace Soon: The battery is functioning normally but holds less charge than it did when it was new.
• Replace Now: The battery is functioning normally but holds significantly less charge than it did when it was new. You can continue to use the battery until you replace it without harming your computer.
• Service Battery: The battery isn't functioning normally. Take your computer in for service. You can continue to use your battery before it's checked without harming your computer.

So, when to replace MacBook battery? MacBook battery must be replaced when it's in Service Battery condition. It is also recommended to replace the battery when its condition is Replace Now state.

Cycle Counts

Recharged Mac Os Pro

According to Apple one charge cycle is when you've discharged an amount that equals 100% of your battery's capacity, but it doesn't mean it should happen in one day.

'For instance, you might use 75% of your battery's capacity one day, then recharge it fully overnight. If you use 25% the next day, you will have discharged a total of 100%, and the two days will add up to one charge cycle.'

Speed demon (brendan a.) mac os. Why is the cycle count number important? Apple batteries can hold up to 80% of the original capacity for a certain number of cycle counts. Once the battery reaches the limit you will see the reduction in battery life (time you can work on the laptop till the next charge).

The cycle count limit depends on the Mac model. Most current MacBook models support a maximum of 1000 cycle limits.

Finding Out the Current Capacity of the Mac Battery

The System Information provides the value of the full charge capacity. This is a current limit. Unfortunately, it does not provide the design capacity so we can find out how much lifespan left with this information.

To find out the original capacity you can download coconutBattery app. This is what it displays for my Mac:

Comparing 3 MacBooks

I have 3 MacBooks at home (don't ask me why):

• MacBook Air 13-inch, early 2014
• MacBook Pro Retina 13-inch, early 2015
• MacBook Pro 15-inch with Touch Bar, 2016

I included the information about the duration I've been using laptops, battery related information from System Information and coconutBattery app in the table below:

Several conclusions after observing the data:

1. MacBook Air after 931 cycles has 86.3% design capacity. Remember Apple promised to retain 80% after 1000 cycles, so it's fair to say they over delivered on the promise.
2. The MacBook Pro 15 inch had been on the shelf for more than a year until I had it. Since the laptop has been properly stored it was able to keep the capacity at near 100% after being manufactured 2 years ago.
3. The cycle count is 30 for MacBook Pro 15 inch. I believe the counter is messed up because I am using this laptop as a Windows computer (I installed a Bootcamp on it). I almost never log in to MacOS and I guess the cycle count is incremented only when the laptop is used with MacOS.

MacBook Full Charge Capacity vs. Design Capacity

Full charge capacity is an amount of charge that the MacBook's battery can hold after being used. Design capacity is how much charge the laptop is supposed to hold from day one.

As you can see from the table above, the full charge capacity of MacBook Pro 13inch is 5910, which is about 90% of design capacity.

Should You Leave Your MacBook Pro or Air Plugged In All The Time

Recharge Mac Mouse

Having a MacBook plugged in all the time will not decrease battery capacity or damage it in any way.

The numbers from the MacBook Pro 15-inch prove that having MacBook plugged in all the time does not damage the battery and does not negatively impact the battery lifespan.

This laptop was used as a desktop computer and was always plugged in, but the design capacity (full charge capacity divided by design capacity) is at 98.4% after 285 days.

Do MacBooks stop charging when the battery is full?

When a MacBook is plugged into a power outlet, and the battery is fully charged, the battery is bypassed, and the MacBook will be using power directly from the power adapter.

However, charging the battery in temperature higher than 95° F (35° C) can permanently damage battery capacity.

On this screenshot, you can see that my Mac is connected to the power, but not charging because it is almost fully charged (99.4%):

Now, after learning so many things about the MacBook batteries it's time to answer the main question.

Apple has a resource which thoroughly describes everything you need to know about MacBook batteries and ways to optimize their usage.

According to this resource, Apple does not recommend fully draining (discharging) the battery. 'If a battery is fully discharged, the battery could fall into a deep discharge state, which renders it incapable of holding a charge.'

If you need to store the MacBook long term, Apple recommends charging it to 50% instead of fully draining. This 50% charge will hold for a period of 6 months. If you need to store for longer 6 months, then it is suggested to half charge the MacBook every 6 months.

How to preserve MacBook battery lifespan

• Avoid exposing MacBooks to high temperatures. The comfort zone for a working MacBook is between 50° and 95° F (10° and 35° C) and you can store in the interval between -4° and 113° F (-20° and 45° C).
• It is Ok to have a colder temperature, in this case, the battery will not be able to fully charge, but there will be no damage. High temperatures, however, ruin batteries.
• Another tip. If you bought a case for Mac and your laptop is constantly getting hot it is suggested to remove the case to achieve higher battery lifespan.
• And finally, always set automatic updates enabled. Apple often pushes energy-saving updates with their software.

Battery Related Questions About New MacBooks

I see several questions constantly popping up on forums related to MacBook batteries and I want to address them here.

How long should I charge my new MacBook?

As previously noted Apple charges new MacBooks at 50% because it's best for storing them in long-term. It does not matter how long the MacBook is charged before the first use, you can start using it right away while having it plugged into the power outlet.

Should I let my MacBook battery die the first time?

No, never let MacBook battery fully discharge to avoid it from falling into deep discharge state.
