Let’s dive deeper into the issue of battery drain in the MacBook Pro 2019. First off, understanding the issue requires some background knowledge. Indeed, the MacBook Pro 2019 comes with a built-in 100-watt-hour lithium-polymer battery. Furthermore, this battery is supposed to provide up to 11 hours of wireless web usage​1​.

Now, let’s define the issue.

In other words, what do we mean by “battery drain”? Specifically, it refers to the rapid loss of battery power. Consequently, the device’s operating time reduces significantly. This is not normal. Markedly, it’s a deviation from the manufacturer’s specifications.

Moving on, how do you know if your MacBook Pro 2019 has this issue?
  • For one thing, you might notice that the battery life is considerably shorter than expected. For instance, it might last for only 5 hours of web browsing. Compared to the expected 11 hours, that’s a big drop. Moreover, the device might shut down unexpectedly. That is, even when it shows that there’s still some battery life remaining.
  • Another key point is to look for signs of excessive heat. Your MacBook should not get too hot during normal usage. Hence, a hot bottom surface could be a sign of a problem. Additionally, the fans might run loudly. In this case, it’s a sign that the device is working harder than necessary.
  • In the light of these signs, you can start to investigate the issue. To illustrate, check what applications are running on your MacBook. In detail, some apps are known to consume more power than others. Particularly, video editing software or games can drain the battery faster. Furthermore, you can look at the ‘Energy’ tab in the ‘Activity Monitor’ application. This tool gives a breakdown of the power usage of each application.
  • Another way to identify the issue is by resetting the System Management Controller (SMC). The SMC controls various functions, including battery management. Therefore, resetting it might solve the problem. To rephrase it, if the issue persists after the reset, it’s likely a hardware problem.

To be sure, you should also consider the age and usage of your MacBook. In similar fashion, like all batteries, the one in your MacBook has a limited lifespan. Thus, if your device is older or heavily used, the battery could be at the end of its life.

Identifying the common causes of why your MacBook Pro 2019 battery is draining fast

Let’s delve into the common causes of fast battery drain in your MacBook Pro 2019. Notably, several factors could be responsible. We’ll explore them in detail.

Firstly, screen brightness can have a substantial impact.

Additionally, the MacBook Pro 2019 has a vibrant, high-resolution 16-inch display. Although it’s stunning, it can drain your battery faster if the brightness is too high. Hence, you might want to adjust it.

Secondly, running multiple apps can sap your battery.

Especially if they’re resource-intensive. For instance, video editing software or graphic design apps. They demand more power. Thus, your battery depletes quickly.

While they’re vital for connectivity, they consume battery power. Particularly when used continuously. Therefore, you should turn them off when not in use.

In another case, software updates can affect battery life.

Initially, after an update, the system might run several background processes. Consequently, this can lead to fast battery drain. However, this usually stabilizes after a while.

Moreover, the health of your battery also matters.

Over time, all batteries deteriorate. This is a natural process. Unquestionably, an older battery will not last as long as a new one.

The sixth cause to consider is the operating temperature.

The MacBook Pro 2019 is designed to operate between 50° to 95° F. If it operates outside this range, the battery might drain quickly. Therefore, ensure your device stays within this temperature range.

Further, the system settings can also affect the battery.

For example, enabling push email notifications or automatic updates can drain the battery. Consequently, it’s wise to check your settings.

Lastly, but importantly, keep an eye on the battery usage.

macOS provides a built-in tool to monitor this. With this tool, you can identify the apps that consume the most power.

In summary, multiple factors can cause fast battery drain. Identifying them is the first step towards fixing the problem. Next, we’ll explore solutions. That’s for another discussion though. Stay tuned.
