British designer Ben Vessey has just released a collection of smart wallpapers to help users track and save battery for iPhone.
Normally, the battery icon of the iPhone is very small, so it can easily lead to users often forgetting to track battery consumption. For this reason, Ben Vessey’s wallpapers are designed with the ability to self-change to notify users about the battery status of the device.
Wallpaper set has 6 different designs, sold on the author’s website for about 6 USD for 2 designs. The wallpaper above is inspired by the Apple Face ID icon. When the battery is full, the wallpaper will be a smiling face with blue rings around. Conversely, tired face with red ring will appear when the battery is below 20%. In the charge state, the wallpaper becomes an unexpected face with golden rays of electricity. 
The first set of wallpapers with 3 shades designed by Ben Vessey. Ben Vessey also designed an apple-shaped wallpaper. Wallpaper will show apple (intact, not bitten in half) when full battery and apple core shape when battery is depleted, simple smiley face is between 20% – 100% battery and a frown face with battery short. All designs are very simple and easy to understand. Ben Vessey shared, the design of 6 smart wallpapers helps solve two main problems. One is that in case the user plugs the charger cord incorrectly so the phone will not recognize the battery, then with smart wallpaper, users will easily detect it. The second problem is that smart wallpapers will report low battery status. “When using the phone, our subconscious mind often ignores the low battery warning of the device. My designs will help users avoid that situation, ”shared Ben Vessey. 
The second set of backgrounds are highlighted with apples. Previously, according to predictions from some technology experts, the new-generation iPhone products can be equipped with Pro Motion technology, 120 Hz refresh rate and 15-20% lower power consumption than iPhone 12. Specifically, the iPhone 13 Pro and 13 Pro Max models will be equipped with LTPO energy-saving screen technology. This screen technology has appeared on the Galaxy S21 Ultra and Oppo Find X3 Pro. The LTPO display can automatically adjust the scan frequency based on the content being played. For example, when the user is playing games or watching action movies, the screen will increase the refresh rate to 120 Hz. When the user is not in use, the screen of the machine will automatically reduce the scanning frequency to lower, helping to save battery power. According to some leaked sources, Samsung and LG Display are in the process of converting production from LTPS to LTPO screens, which could be completed in the first half of 2021. However, there are opinions that capacity to make LTPO screens lower than LTPS because companies have to add some manufacturing processes.
