Is it true that 5 minutes of charging can lead to 2 hours of talk time?

Is it true that after five minutes of charging, two hours of talk time can be achieved? In fact, "charging for 5 minutes and talking for 2 hours" refers to the VOOC flash charging function of OPPO smartphones. After testing, OPPO's VOOC flash charging technology can charge 75% of the phone's power for 30 minutes when the phone is out of power. Charging for 5 minutes can reach about 15% of the power (battery capacity is 3000 mAh). The 15% of power is basically ok. Maintains 2 hours of talk time. So what is the principle of VOOC flash charging technology that can charge for 5 minutes and talk for 2 hours? What technology is it? The editor has compiled some knowledge about VOOC flash charging here, you can check it out. I believe you will find the answer after reading this!

After testing, the power consumption of OPPO R7 during a call for half an hour (30 minutes) is 2. Then the power consumption for 2 hours (120 minutes) is 8, and the power consumption reported by consumers is 3 for half an hour, and the power consumption for 2 hours is 12. Pretty much the same as the actual test. OPPO's VOOC flash charge can charge about 15% in 5 minutes, which can sustain calls for about 2 hours.

How to quickly introduce water from pool A (external power supply) to pool B (battery)? We can increase the pressure to accelerate the flow of water from Pool A to Pool B (as shown in Figure 1), but this will lead to an increase in heat and is prone to safety problems; of course, we can also increase the transmission area (i.e. broaden the connectivity The area of ??the pipe) accelerates the water flow (as shown in Figure 2), but this simple method of expanding a single channel will double the instantaneous pressure on Pool B, which will also cause safety hazards; what should be done?

In fact, we can add multiple balancing pipes (as shown in Figure 3) so that the water can flow to the pool smoothly and quickly without generating the multiplied pressure of a single channel. (OPPO’s VOOC flash charging uses this principle, so it is relatively safe)

Let’s talk about the principle of VOOC flash charging.

Now we might as well take a look at the two distinctive hardware designs of the "5-minute charge, 2-hour talk" VOOC flash charging system - a 7-pin microUSB interface and an 8-metal contact battery. Generally speaking, the conventional microUSB interface has 5 pins, while the mobile phone battery has 4-5 contacts (some have 3 pins), but OPPO Find7 has 7 pins and 8 contacts. The extra pins and The contact point is actually equivalent to the channel connecting pool A and pool B. By adding a balanced passage between them, the purpose of quickly introducing the water from pool A to pool B is achieved. This is "charging for 5 minutes and talking for 2 hours" The principle of VOOC flash charging fast charging!
