Today, iPhone battery consumption depends on so many factors that more than one user takes wildly exaggerated measures to minimize it as much as possible. Like this almost obsessive habit of closing all applications shortly after opening them. When talking with friends, I see habits based on things that border on urban legendtherefore it is important to take action based on proven facts.
If you think your iPhone battery is draining too quickly, don't worry: we've all been there. And in iOS 18, there are a few settings to check that are probably responsible for this exaggerated consumption.
The screen will always be the main cause of battery consumption on the iPhone
Maybe at specific times an app is consuming a lot of battery on your iPhone, or you're simply traveling by car or train (causing you to consume battery power by constantly moving between cell towers ). But if you think your iPhone battery is draining too quickly, you can do a quick check in iOS 18's Settings (although the same is done in iOS 17).
If you own an iPhone 14 Pro, iPhone 15 Pro, or iPhone 16 Pro, keep in mind that its always-on screen feature may drain your battery faster. You can disable it, which we recommend, by following these two steps:
- Go to “Settings” on your iPhone
- Now scroll down to the “Display and Brightness” section:
From this same section you can also reduce the screen brightness, which also contributes to greater battery consumption if it is very high.
The second setting is aimed precisely at this brightness, which automatically dims depending on lighting conditions of where you are. This not only maintains the brightness you need at all times: it also saves energy when you don't need all the lights. slow what the iPhone screen offers.
It is possible that for some reason this option is disabled. You can re-enable it from Settings, in the Accessibility section and in “Display and text size” option:
The option itself already tells you: it is better to have automatic brightness activated to optimize the life of the battery and even the screen in the long term.
Other possible causes of excessive battery consumption
If you want to look at more possible causes of excessively high battery consumption on your iPhone, keep in mind that We talked about several options beyond what the screen and its brightness can cause:
In the end, I always say the same thing: we must not let ourselves be overwhelmed. Over time, the battery of our electronic devices degrades, this is one of the limitations of the technology they use. And that includes our iPhones too. But these simple requests can help us mitigate this effect and extend the life of our phone a little more. Finally, remember that you can always change the iPhone battery. Depending on usage and warranty, sometimes it can be free.
