Is Pcmark10 battery life representative?

Pcmark10 battery life is not representative. KOLs like to use PCMark10 to test battery life. However, there is a problem with PCMark10's battery life test. Its test environment is not fixed, such as the screen. Brightness, manufacturer's performance mode, Windows power mode, WIFI switch, Windows Update switch, etc. will greatly affect the final results. The test environment of each KOL is different, and even the same KOL at different times. The testing environment is not necessarily the same, so it is difficult for you to horizontally compare the PCMark10 battery life scores of different models tested by different KOLs or even different models tested by the same KOL at different times, so there is room for manipulation. For example, I once I’ve seen people adjust the screen to a brightness of less than 100 nits to achieve excellent battery life performance. Just imagine that the brightness is so low that the eyes cannot be blinded [vomit]. Even in the power-off mode, we also recommend that the screen brightness should not be lower than 200 nits. , so if you see that the battery life of a certain laptop is measured at 150 nits, you should think more about whether you can accept it.

However, one advantage of the PCMark10 battery life test is that it will also give a performance score. Generally speaking, for laptops with similar configurations, performance scores and battery life see-saw. If the performance score is high, the battery life will be shorter, and the battery life will be shorter. Performance scores that last a long time are usually not high. For example, the PCMark10 battery life performance score of the first wave of ThinkBook 14 i5-12500H evaluation is about 6000 to 7000 points. If you pay attention, you will find that this score is different from another machine that claims to have a very good battery life. The performance score of the good i7-12700H is about the same or even slightly higher, while the KOL evaluation performance score of a certain Taiwanese OLED screen 15.6-inch i5-12500H model that claims to have better battery life is only over 4000 points, which is as low as a famous American 16 :9 The i5-1235U U15 of the business notebook is similar, and the power setting is also very low. This is very interesting. The lower power limit of the standard voltage processor is higher than that of the low-voltage processor. Isn’t it scary to set such a low power? Is it stuck? Of course, we are also reflecting on whether our performance settings under off-grid conditions are too aggressive. We do not rule out that in the future we will make some optimizations to off-grid performance and extend the battery life.

Having said all this, I would like to remind everyone that when looking at the PCMark10 battery life results, you must pay attention to the test environment conditions and performance scores at the same time in order to draw a more complete conclusion.

In addition, I want to reiterate that you should not test the battery life when you get the new phone, because there are usually many background software updates at this time, and the user does not know the battery life measured at this time. The time will be much shorter than when there is no background update. Some of the more extreme battery life on the Internet are estimated to be measured under this situation, and there is no reference. (BTW, some users reported that the new phone did nothing but the fan kept spinning, which was also caused by the background update. It is recommended to observe it for a period of time. After the background update is over, this phenomenon usually disappears until the next background update^_^ )

Finally, here is a screenshot of the ThinkBook16 i5-12500H core display model’s PCMark10 battery life score of 10 hours and 50 minutes (please try your best to complain about the poor image quality). The test conditions are 200 nits brightness, Fn Q energy-saving mode , Win11 power mode is the best energy efficiency, WIFI is on, Bluetooth is off, and see if it is better than the Taiwanese OLED screen 15.6-inch i5-12500H model that claims to have better battery life? In addition, PCMark10 battery life results also have a certain range of fluctuations. We have also achieved results of 11 and a half hours or even 12 hours with the same configuration.
