With the full popularity of full-screen phones, more and more mobile phones are beginning

to use OLED screens. OLED screens have many advantages, such as thinner thickness than

LCD screens, lower power consumption, flexible bendable display and profiled screen, and

response time is one-thousandth of the LCD. Therefore, Apple uses OLED screens on iPhone

X, iPhone XS Max, and iPhone XS.

However, tests have shown that the iPhoneXS’s endurance test results are worse than the

iPhoneX. Nowadays, the power consumption of mobile phones is increasing day by day.

Many mobile phone brands have extended the battery life by increasing the battery capacity.

For example, the iPhone XS Max and iPhone XS have larger battery capacity than the previous

generation iPhone.

Before the discovery of new battery technologies, battery life may be further reduced as companies

such as Apple adopt more advanced but more power-hungry technologies. For example, newer,

higher resolution displays and the upcoming 5G may have a serious impact on your phone’s battery

life. I hope that battery technology can make a big breakthrough.

The stunning OLED displays on the iPhone XS and XS Max work well, but they may consume more

power than traditional LCD panels, and the extra power consumption exceeds the capacity gain of

battery improvements. That’s why the iPhone XR’s screen is larger than the XS, but it’s three hours

longer than the iPhone XS in the battery life test.
