When we buy a new portable computer we look for relevant aspects such as its memory, its type of disk or perhaps the technology of its screen but very rarely do we worry about an essential aspect such as the battery and its useful life, and that although in theory The life of the battery in a new device must be wide, the constant use of applications of high use of this resource together with internal and external factors can cause a negative impact on this and thus lead to errors that will affect at any time the optimal use of the equipment..
The battery is an essential part of any portable computer because if it fails and we are not near any electrical outlet, the equipment will simply shut down and we will not be able to do anything. It is important therefore that the battery of our portable device is optimized, as this will help us to prolong its use when we cannot connect it to the power. Apple has launched macOS Mojave with a number of new features and improvements seeking to improve all overall user performance, but some have reported battery failures or excessive use on computers such as MacBook, MacBook Pro or MacBook Air.
Perhaps one of the questions that arises is, if Apple has launched macOS Mojave should not be assumed that this system should be more stable and optimize the use of resources ?. Well, when we have updated to Mojave, this system executes various activities and background tasks for its features such as Spotlight indexing, photo indexing or iCloud data management and synchronization, all these background tasks make a Battery consumption without us noticing..
One tip for this case is to leave our portable equipment connected to the power outlet and turn it on for a considerable time, a good practice would be to leave it on overnight and use a screen protector or turn off the screen, with this macOS Mojave will complete the background tasks that are necessary, normally these background tasks must be completed in an average of 1 to 2 days, and thus Mac performance and battery life should be in their best condition.
TechnoWikis will make a complete analysis and a series of tips to see the alternatives as we can improve the life of our battery in macOS Mojave and thus not incur unnecessary expenses due to poor administration or use of the equipment. It is important to be clear about the autonomy of the original battery of our Mac, because the batteries are developed with a limited amount of charge cycles before they become considered depleted, which results in the purchase of a new battery
