Dark Mode(Dark Mode)It is an important feature on smartphones now，Apart from making the phone screen less dazzling in dark environments，Power saving is also one of its major advantages。However，The premise that turning on dark mode can bring power saving effect is that the material of the mobile phone screen must be OLED。So，If the LCD turns on dark mode, can it bring power saving? to this end，A foreign blogger used iPhone 12 and iPhone 11 to conduct a series of comparison tests on turning on dark mode on mobile phones。
For OLED and LCD，We should already be familiar with their characteristics。Here, the iPhone 12 uses an OLED screen，The iPhone 11 is an LCD screen。In terms of battery capacity，iPhone 11 has a 3110mAh battery，The battery capacity of iPhone 12 is 2815mAh。
Start the test below，The first round is a one-hour test。The battery remains on 100% of the time。have to be aware of is，The entire test also added the iPhone 12 to turn on daytime mode for comparison。
One hour later，iPhone 11 with dark mode turned on has 97% of its battery left，The iPhone 12 has the same battery life in daytime and dark modes，All are 98%，In this round of tests，Turning on dark mode has basically no effect on battery life。
The second round is one-hour text message test。After the end of this round，The iPhone 12 with daytime mode is the same as the iPhone 11 with dark mode is the same，All have 88% of the power left，The iPhone 12 with dark mode has 91% of its battery left。In this round，iPhone 12 with OLED screens starts to show a slight advantage。
The third round is one-hour email browsing test。In this round，The iPhone 12 with daytime mode turned on continues to be on par with the iPhone 11 with dark mode turned on，All have 80% of the power left。The iPhone 12, which turns on dark mode, further widens the gap，86% of the battery left。
The fourth round is one-hour web page viewing test，have to be aware of is，Not all web pages are adapted to dark mode here，Some web pages are still displayed in black and white。So the final result is，iPhone 11 with dark mode turned on has 70% of its battery left，iPhone 12 with dark mode turned on 77% of its remaining battery。Compare the remaining power of the previous round，Turn on dark mode in this round has little effect on battery life。
The fifth round is one-hour social media test。The result is that the remaining 70% of the battery power of the iPhone 12 with dark mode turned on，Consumed 7% of the power。The iPhone 11 with dark mode has 60% remaining battery power，Consumption of 10% power，The remaining 62% of the battery capacity of iPhone 12 with daytime mode is turned on，Consumption of 9% power。
From this we can also infer that the power consumption of iPhone 11 with dark mode and iPhone 12 with dark mode is basically the same as the power consumption of iPhone 12 with dark mode is basically the same，From another perspective, turning on dark mode on mobile phones equipped with LCD screens cannot achieve the purpose of saving power。
Testing continues，After 16 hours of standby、One hour video、After one hour of game and 55 minutes of analogy navigation，iPhone 12 with dark mode turned on has 24% of its battery left，iPhone 11 with dark mode turned on has 11% battery power，The iPhone 12 with daytime mode has 15% remaining battery power。
Finally, there is an hour of music playback test。The iPhone 11 with dark mode has run out of power when the countdown is 12 minutes left，The iPhone 12 with daytime mode has 4% more battery power，The iPhone 12 with dark mode has 13% more battery power。
From this series of tests，We can already see that the mobile phone equipped with LCD screen does not have the ability to extend battery life by turning on dark mode on.，It is not much different from turning on daytime mode。And this result seems to tell us，If you use Dark Mode frequently and want to get the effect of extending the battery life，Then it is best to consider a smartphone equipped with an OLED screen。
