The life of a common smartphone battery may be reduced due to the increasing demands of new technologies to support lithium-ion batteries.
In a series of tests where multiple smartphone battery models from the past few years were set at the same brightness and made to reload the same sites and observed. The test showed that newer smartphones were not able to last as long as the older ones.
Meaning, that the iPhone XS died at an average of 21 minutes earlier than the iPhone X. The impact of battery life was most prominent in the Google Pixel 3, which went out an hour and a half before the Pixel 2.
The Washington Post reported that the iPhone XR, which uses an LCD display instead of an OLED, was a notable exception, as it performed well on the battery life tests. Apple boasts that the iPhone XR has the longest battery life of any iPhone, amounting to 25 hours of talk time, 15 hours of internet usage, 16 hours of video playback, and 65 hours of audio. Proving their point the new device lasted the longest in the battery test, besting all other latest competing phones in the test. These included the Pixel 3XL, the Samsung Galaxy Note 9, and the iPhone XS Max.
Apple’s iPhone XR scales back on the screen tech with lower resolution, less bright and lower-quality color. These factors help it in ways that benefit battery life tremendously. It even lasted 3 hours longer than the top iPhone XS in the test.
Nadim Maluf, CEO of battery optimization firm Qnovo, observes that though batteries in smartphones increase at a rate of 5 percent per year, their power consumption is growing at a much faster rate.
Battery company Onavo’s CEO believes that consumers should either start to compromise for smartphones with increasingly bigger batteries that result in larger, heavier devices or else go for lesser technologies like the LCD display.
