In this article, we'll look at common problems and 5 fixes for these MacBook and MacBook Pro battery problems.
Why is my Mac battery draining so fast?
There can be a number of reasons. For example, different browsers consume different amounts of battery power.
In some cases, a recent upgrade to a new macOS can be the cause and therefore a temporary problem. It either stops doing this in its own time, or a new macOS patch/upgrade is sent through and once downloaded the problem goes away. It is known to happen around the time of new releases and is an issue many Mac owners anticipate.
However, in other cases, the issue is less widespread and more localized. We cover five of the most common problems and fixes for Mac users, in particular MacBook owners who have suffered from a fast draining battery.
5 solutions for Mac battery problems

4. Identify background apps
Apps For Mac
Behind the scenes, most Macs can run dozens of apps without us realizing it. Some of these could be running because we forgot about them. Others open during the startup sequence. And others, without us knowing it, could be malware or ransomware, or other viruses, either designed to steal data or steal processing power to mine cryptocurrency or even run remote DDoS attacks.
Now, clearly that sort of thing isn’t ideal and you won’t want apps running that drain power, steal data, or that use your Mac for something you aren't even aware. To solve these potential battery draining problems, we recommend taking the following steps:
- Download CleanMyMac X (for free, here)
- Click on Uninstaller
- It will run a scan of every app on your system: Either click to rest or safely uninstall everything you don't need or aren't aware of.
Also, click the Optimization tab in CleanMyMac. You’ll find the tool called Launch Agents.
