Editor's note: There are many mobile processors with different architectures on the market. The names A7, A9, A15, Krait are all familiar to players. We have already published about these architectures Performance comparison of the same frequency , and this is a comparison of power consumption of SoCs of different architectures on the same frequency.

The parameters of the five machines tested are as follows:
A7: U956 battery capacity: 2500mAh, 9.2Whr
A9: Note2 Battery capacity: 3100mAh, 11.5Whr
Krait200: XperiaZ， Battery capacity: 2330mAh, 8.6Whr
Krait300: millet 2S, battery capacity: 2000mAh, 7.4Whr
A15： Galaxy S4 ， Battery capacity: 2600mAh, 9.6 Whr
The test method used this time is as follows:
All flight modes of five mobile phones, Bluetooth, GPS, etc. are closed. The screen brightness is the lowest, and the CPU frequency locking is at 1GHz, and the quad core is fully open.
The first time is the full load test. Use the Classic Test of Stability Test to conduct a complete discharge and record the discharge time.
The second time, no load test, other conditions remain the same, do not run the Stability Test, the CPU drops to the lowest frequency, only displays a picture the same as the Stability Test, and records the discharge time
When everything is turned off, it can be considered that the overall power consumption of the mobile phone=CPU power consumption+screen power consumption
The first test can get the overall power consumption of the mobile phone
In the second test, when the CPU load is almost zero, the power consumption of the CPU is ignored, and the overall power consumption of the phone=the screen power consumption
Subtract the screen power consumption of the second blank test from the overall power consumption of the phone in the first test, and the result can be considered as the full load CPU power consumption
The test results are as follows:
Note2， The test result with full load is 4.9 hours
No load test result, 50% of remaining power after 8.6 hours
M2S: 2.3 hours of full load endurance
50% remaining after 4.7 hours of no-load endurance
Xperia Z
Full load endurance results in 3.0 hours
No load endurance test, remaining 49% power after 6 hours
Galaxy S4
2.6 hours for full load
No load test, 57% of the remaining electricity after 6.8 hours
U956
Full load endurance 7.4 hours
No load endurance, remaining 55% power after 11.2 hours
