How to improve your iPhone X battery life: 3 quick and easy tips and tricks

Battery charge is one of the many things we'll never have enough of, it seems. Even today's top phones can barely get us through two days of use, and nothing leads us to believe that the situation is to improve anytime soon. Hardly a surprise, our articles with tips and tricks on improving smartphone battery life draw quite a lot of attention. Articles like the one you've landed on, dedicated to the fancy, flashy iPhone X.

So, how do you improve your iPhone X battery life? Well, you cannot swap the stock battery cell for one with a larger capacity, but you can control how its charge is being consumed. As the case is with every other phone, the display is one of your iPhone's most demanding components, and we're about to give you a handful of tips on how to limit its power draw. 

But first, a quick refresher on how modern displays work. On one hand we have LCD, which is still the dominating smartphone screen technology. Basically speaking, an LCD panel uses a white backlight, and every pixel acts as a filter in the light's way, letting through only the color it is instructed to display. This backlight is constantly lit, even when the whole screen is showing the color black. With OLED screens, on the other hand, every pixel produces its own light, hence the dimmer a pixel is, the less power it consumes. As you might recall, the iPhone X is the first iPhone with an OLED display. Therefore, the greater the presence of black on the iPhone X's display, the greater the power savings.

Tip #1: Change your wallpaper

Taking advantage of the power-saving potential of the iPhone X's OLED display is fairly easy. For starters, you can switch to a black wallpaper, such as the one that already comes pre-loaded on your iPhone X. Using a power measuring tool, we detected a 20% decrease in total power use when we replaced the iPhone X's default wallpaper with the black one. The result was obtained at 50% brightness without altering the brightness level between individual measurements.

Alas, an entirely black wallpaper is kind of boring to look at. The good news is that you can still enjoy some power savings if you choose a wallpaper that's predominantly dark. In fact, we have several great selections of wallpapers for OLED displays, with images that both look great and save power along the way.

Tip #2: Use dark mode in apps that have it

The iOS interface is bright, lively and colorful – this particular aspect of Apple's software experience isn't customizable. Apps, however, can follow any color scheme built into them by their developers. There's a number of popular apps that go for a darker look. Apps like Spotify, for instance, or iOS's own Clock app. Other apps give you a dark mode as an option. For example, Twitter has a Night Mode built into it, available from the Settings menu. So do Reddit, Wikipedia, and the cool Mini Metro game. Also, Amazon Kindle and Apple iBooks can display white text against a black background instead of the default black-on-white approach. So if you find yourself using a particular app all the time, check if it has a dark theme as option, or see if an alternative to that app has one.

Tip #3: Use the "hidden dark mode" in iOS

In its current state, iOS does not have a dark mode, a dark theme, or a night mode, hidden or not. However, many refer to the platform's built in Smart Invert feature as such. When active, this mode inverts the colors of UI elements, yet leaves certain graphics like photos or videos unchanged. And since iOS's interface is dominated by whites and bright colors, inverting them leaves you with a "dark theme" of sorts across apps and iOS itself, thus saving you battery. Smart Invert can be found in the Settings menu, under Accessibility > Display accommodations.

Frankly, we are not in favor of using this mode all the time, simply because it takes away from the iOS experience. But if you're in a situation where you know you won't be near a charger anytime soon – during a flight or a long commute, for example – iOS's "dark mode" could be of use. Now go read our article on how to activate Smart Invert dark interface mode on your iPhone X.

You don't have to do any of those, my wife iPhone X's battery has been great so far and she had every setting turned on. You can leave that phone for hours, and it won't lose even 1% of it's battery.

It does get great standby bro. My wife ordered hers last night, and I bought her AirPods. I told her how much your wife likes hers, she’s excited.

I feel Apple dropped the ball here. You give us a beautiful OLED display, but not the dark themes to take advantage of the battery life saved by dark themes. You instead stay with only a light colored UI...working against the battery. This is why Apple sorely needs iThemes. As much as I like this phone, I bought it outright, and will criticize its weaknesses. Smart invert is cool, but not all apps support it yet, therefore I found myself turning it off and on at times. I have a white leather background right now, and refuse to restrict myself to only dark backgrounds. Battery life has been great, so no worries, but just give us themes like Samsung and LG do. C’mon Cook.

Yeah Apple should take a page straight out of Samsung/LG and do the theme thing. I absolutely love the Samsung theme thing on Galaxy devices, it does really change the feel of it

Right man, that would be lovely. That’s one of my favorite Note features. Get bored with the look (I get bored ultra fast), just change it.

With themes the problem is that the UI isn't unified. Themes only change some parts of Ui, idea with iOS is that everything feels like part of OS. Apps and OS have same design language it feels like those apps belong to iOS. With Android this isn't the case.

Nahhh man...try themes on an S8, or Note 8. They’re seamless, and Apple could just make the themes look as if they belong. Don’t make excuses for Apple’s reluctance. This is sorely needed. I’m a fan of Apple’s tech, but I’m also a realist, and call it like I see it.

You got it all wrong, Apple have their own iOS Ui design guides, 3rd app developers try to mimic iOS style and feel so it gives that unified experience, let say you buy new app and you right away know how to use it because it has that familiar feeling and style and very likely same navigation and icons. If you change your iOS Ui with themes those 3rd apps can't get the same style. Also devs can't follow because they doesn't know what themes people use. So no it's not what Apple does, it's what 3rd developers do.

Stop making excuses dude. iOS needs a UI overhaul. Simple as that.

I like the UI, but it needs to be reorganized a bit. Some things are forced a bit - specially how you have to pull down for control center is extreemly unintuitive.

Right! I’m no dogging the UI, I like it, but it can use an overhaul. That’s all I’m saying.

Been using the X since day one and that's one of the things I miss is themes.. I find myself using my note 8 more often because I can customize and find dark themes. The gift and the curse of ios... Simplicity yet boring...

Yep, that’s my biggest gripe with iOS. I love the intuitiveness, but man can it be boring at times. I do love the X, and what Apple did with the software, but as much as Apple and Samsung copy each other...Apple should copy split view floating windows picture in picture, and themes. The iOS experience would greatly improve from it in my book. As it is now, I’m picking up my Note 8,or iPad Pro for certain things. That said, I love the continuity experience, and seamless integration between my X, Apple Watch, iPad, AirPods, and Apple Pencil. It’s all about the user experience for me, and Apple delivers a better one across its product line than Samsung does for me.
