No matter how strong your allegiance to Android or iPhone is, you’ll probably agree that the worst thing about Android phones and iPhones is battery life. Yes, most of the new phones will get you through the day, and the advantage is clearly on Android, as some vendors have equipped their devices with massive battery packs. But battery life is never enough, especially as the battery degrades over time. Thankfully, Google just told us how to improve battery life on certain Android and most of the new iPhones, admitting a mistake in Android design in the process.
It turns out it’s something as easy as switching to dark mode whenever possible. That’s something smartphone-savvy users have long suspected, that dark mode will help conserve battery life. There is a caveat, however. The screen has to be an OLED one. But that’s absolutely not a problem these days, as most of the flagship devices out there pack OLED screens, premium iPhone X versions included.
Google shared data about energy consumption on phones at this week’s Android Dev Summit, SlashGear reports.
The company studied energy consumptions on phones with white and dark themes and concluded that at max brightness, the dark mode on OLED always wins. With OLED screens, each pixel lights up independently, which is why dark mode helps preserve battery life.
Google also showed a comparison between the original Pixel and the iPhone 7 which is self-explanatory, as long as you’re aware of the screen differences between the two devices. OLED, on the original Pixel, does consume less power on dark mode compared to the iPhone 7, which has an LCD.
All Pixels since the Pixel 3 come with OLED screens, as do Samsung flagship devices like the Galaxy S or Note, and Apple’s iPhone X, iPhone XS, and iPhone XS Max. But you won’t really find true dark modes for any of them.
Even Google admitted that it was wrong to impose white as the predominant color for Material Design apps. Apple’s iPhone UI, meanwhile, is also heavy on white, and there’s no dedicated dark mode on iPhone either. Interestingly, Apple launched a dark mode for Mac, although all Macs have LCD screens, which means it won’t help with battery life. Samsung phones, meanwhile, will get a dark mode via the One UI update, but not all its phones are eligible for it.
Just because Google told us how easy it is to “fix” battery life on OLED smartphones, doesn’t mean we’re getting dark modes from either Google or Apple anytime soon. But there may be independent apps that may offer users dark modes, with YouTube being one such example.
