At What Cycle Count Should My Mac Battery Die

To maximize your laptop time, you’ll want to keep an eye on your battery’s cycle count. My Mac’s battery just reached below 11,000 and I’m wondering what this means for its health.

What is the battery life cycle?

There’s an infamous old joke that goes a bit like this:

We know that when we charge our laptop’s battery, the power from the charger gradually charges the battery. This cycle is known as a ‘daisy-chain’ or ‘voltage decay’. The length of this process varies day to day as well as for different laptop models and internal components. For example, many newer laptops have much faster charge cycles compared to older models which might last 3 hours on their original charger.

For iphones, the expected battery life cycle is around two years. For macbooks, they typically last four to five years.

How do you know when your battery is done?

The battery in a laptop won’t last forever and eventually, it dies. But how do you know when the best time to replace this power supply is? The six lead-acid batteries, Ni-Cads, or NiMH recharged by four AA batteries require 24 approximately 025 watts/hour (w/h). A cycle count of 50 means that the battery loses 9% of its capacity every hour.

The recommended cycle count is usually indicated by the type of batteries used. For example, type 26650 battery will reach typically around 350 charges and Discharged voltage will typically reach -15V. However, at what cycle count should my mac battery die? There’s no definitive answer as an exact value cannot be established since some may last longer than others depending on how they’re taken care of.

In order to know when your battery is done, you just need to go off of your cycle count. This is the number of times that your battery has been charged and discharged in a day. Once that count exceeds 100, this means it’s time for a new one.

How do I know my battery is dying prematurely?

The short answer to this is that you can’t tell. Both the battery life on Macbook Air and other Apple laptops is designed so that it isn’t ever certain when your laptop will reach the end of its life. It’s simply impossible to say with any certainty when a Mac battery will require replacement, but there are a few things that may help you predict your battery’s lifespan. One way to determine whether your Mac battery is in need of replacement is through “Garage Test”—instead of waiting for your computer to notify you (while driving down the highway or sitting in line at Starbucks) that it’s time, go into the settings menu and test it yourself using the simple steps below:

Battery cycles are a measure of how many times the battery charges and discharges over its estimated lifespan among Samsung Galaxy Note 9 owners on Reddit. But what happens if you don’t really know when to replace your battery, because there’s no destination to plug in your phone to monitor the battery condition?

Say you’re using your laptop on the beach and it suddenly shuts down. If it dies too soon, this could be a sign that the battery is dying prematurely. There are three factors to consider when determining the life of a battery: temperature, charge cycle, and deep discharge cycles. Using these factors can make it easier to predict when a battery should be replaced:


Apple batteries only die at a fixed rate, so it is recommended that the battery’s cycle count reflects this. A macbook with a cycle count of 120 claims that on a regular basis, their battery can last up to six hours while in energy saving mode.

To help avoid the risk of battery being too low, set your computer’s power management settings to put it in sleep mode after a certain number of minutes of inactivity.

If there is a cycle count for your mac battery, then that would determine its life. The cycle count for most mac batteries stay at about 400. If it falls below 80 from that number, then you need to replace it with a new one.
