From the first use to when you finally replace your worn out laptop with a newer one and purge all the data, Apple users spend an average of about 27% of their life with an Apple laptop. With many handy features on these computers, it’s not surprising that people get so attached to them – hundreds of thousands even go as far as adopting it as their second child including their own personality into this technology by naming them “Millennials”.
What does the Battery Cycle Count Mean?
Battery cycle count is a number that shows the charge cycles that the batteries of your specific device have been through. Apple suggests standard charges be between 400-500 cycles. Users can also contact Apple to request additional charges, usually at no cost.
A battery cycle count indicates how much a device’s battery is used while being idle. A single charge on a laptop lasts 42.7 Watt Hours. Therefore, that means that one full charge goes through 400 cycles. With each cycle, there will be minimal loss in the amount of charge left as well as in the amount of power it outputs.
Each time you let the battery discharge, all of its chemicals diffuse in the air and create new, unrecycled molecules. This results in a lower overall efficiency for the battery. When you have a greater number of cycles in your battery, it will be more efficient and offer more reliable performance. A longer battery cycle count might even increase your laptop’s lifespan 5-10%.
How Many Battery Cycles Does a Macbook Pro Have?
MacBook Pro’s battery cycle count is about 3,000. That means that after 3,000 charge/discharge cycles these batteries usually only have about 72% of their original capacity.
A laptop battery typically lasts anywhere between 2-5 years. The longer you use your laptop, the more wear the battery cycles will accumulate. At its best, a 3 year old Macbook Pro will have about another 400 to 500 cycles left on its lifespan.
The maximum number of battery cycles for a MacBook Pro is said to be 17000. Another popular question is how many times a laptop battery can go through ‘a full charge’. The time it takes to fully recharge the MacBook Pro’s battery may vary but most modern day laptops have settings that allow the battery to charge at least 95% in time.
Effect of Temperature on Battery Life
Battery life is affected by how a specific electronic device is being used. In the average laptop battery, temperature affects how one recharges the batteries but also can degrade it’s lifespan. A laptop that is overheating slowly will charge its battery less efficiently than a cooler laptop. If a laptop gets too hot, it can even start to permanently cook the cells in the computer which means the computer will possibly cease to work properly and need replacement parts.
Battery Life is decreased as temperature increases. The more the battery is overheated, the more quickly it degrades. This is due to lithium-ion batteries releasing free radicals when they are switched on, clumping together and degrading the separator membrane of all cells. These separators regulate how much current passes from one cell to another (and hence how full the battery gets), and so a degraded separator membrane leads to poorer performance.
Technically, a battery is an energy storage device that produces electricity as it converts chemical energy directly into electrical energy. The main factor in determining how long your battery will last is its maximum charge and discharge rates. You can get information about the load cycle count of your batter on Apple’s website
The maximum battery cycle count for a macbook pro is about 300 cycles.
In conclusion, lithium-ion batteries have a discharge curve that can be described by a plot of ampere hours over charge cycles. It has a 3-stage graph with minimum capacity, ideal capacity and maximum capacity. It also forms a U-shaped orange line in the middle representing peak performance levels.
One of the most important things when MacBook Pro batteries degrade is its performance speeds. The maximum battery cycle count for a MacBook Air is 250,000 and a Pro is around 300,000. So good luck with that!
