You need a well-functioning battery if your laptop or portable device is to run properly. But how can you tell how much charge your battery has left? The best way to do so is by checking the voltage. Using a multimeter, as you would in most DIY repairs, is perhaps the easiest method, but are you really familiar with this tool and its intricacies?
Check the battery level in your MacBook
One way to check the battery level on your Mac is to have the power information menu. It can be accessed by holding down command and F6 while the machine is powered on. This menu will show a usage trend, as well as options for managing power settings.
In order to check the battery level in your MacBook Pro’s Power Adapter, follow these instructions. To do this on a Mac that meets
the requirements for this command, open up the Terminal app.
Type the following line into the Terminal: ithings you can do here
Your MacBook battery level can be checked in a number of ways. First, take the lid off and pop out the battery. Then, cradle it with your fingertips at the same level on either side. If you see two green lights, it is fully charged. If they are yellow or orange, plug your MacBook in to charge it.
Understand Apple’s battery charges
To check your laptop’s battery charge, look at the battery icon on the menu bar. This can be found by pressing ⌘ + 5 on PC and looking to the left of the time. If you see four bars that are filled light blue, it means your laptop is fully charged and as a result, it will last as long as possible if draining power at a slow rate or if not used for any extended amount of time. It will gain power over time if not in use (meaning down to two bars). If you see one or two green bars, it means your laptop’s battery charge is diminishing but still has a good amount of energy left even though you won’t get the full life-span of your charge when in use.
To check the battery status and charge on an Apple laptop, there are a few different methods. Opening up the
Apple MacBooks are expensive, but can also be easily broken. Sometimes people break their MacBook because of a charging cable mishap, or the battery itself. If you want to know how many cycles your battery has gone through, there is a setting in your computer dashboard by clicking on the battery icon in the top menu to get your cycle count.
Battery charge cycle and other helpful facts
The average battery has a specification lifespan of 1,000 charge cycles. If a battery is billed at maximum capacity, it will typically never die because each charge cycle will slowly wear down the battery’s capacity. As stated by Mac Basics, the best way to verify your battery capacity is to bring it in and get it tested.
MacBook Pro batteries have been known to have a limited lifespan, so it’s important to keep track of how many times your battery has been charged. You can run an outdated Mac app called Hardware Info and enter your machine’s serial number to find out about the number of past charges on your battery.
Every year, Apple replaces the lithium-ion battery in your MacBook Pro. It won’t last forever, but a good rule of thumb is to count your battery cycles and then check its capacity against your manufacturer’s recommendations. Another pro tip: always keep your MacBook Pro plugged in when you don’t use it
Using your Macbook with a USB-C charge
A USB-C charge will play a major role in your laptop and is one of their main sources for power. Since the USB-C has become a standard for laptops, you should know how to check your battery count with it. The MacBook’s specifications says that your laptop will always have enough power on this port, which means that you can use your Macbook while charging up the battery. So long as the MacBook is plugged into its ability, it will not shut off unless the battery reaches 0%.
One of the drawbacks in using MacBooks is that you can only charge via USB-C. This can be problematic when you want to plug in a laptop charger, or even just a regular old USB cable. For example, if your battery life is getting low, or you’re on your daily commute, it may be hard to find any outlets at all. You can check the battery’s status by going to System Preferences > Battery, which will give you a percentage of remaining charge as well as notification when it gets too low to charge.
When using your Macbook for a long time the battery can die before you know it. A characteristic of USB-C is that it can be charged with old laptop chargers. This makes it easy to keep your laptop and battery on the go. To check the laptop’s battery status, plug the charger into a power outlet and connect one side of your computer’s charging cable to the USB-C port and the other side to a wall outlet, USB port or other device that you want to charge. Different technology used in these two ends, but even low current count will ensure high voltage input.
