August 14 news, mobile battery has been nearly 50 years of development history, but unfortunately the phone battery capacity has not made much breakthrough. In this context, many smart phone manufacturers began to one of the battery-related features as a promotional selling point, that is fast charge. If the latest iPhone and Android flagship contrast, you will find a phenomenon: iPhone than some Android flagship mobile phone charging speed is slow.

This is the fact that many media evaluation video has confirmed that some Android flagship, such as Galaxy S8 charging speed is indeed faster than the iPhone 7, and Galaxy S8 + charging time than the iPhone 7 Plus about 1 hour.

Have to say, fast charging is a very useful feature, as short as possible to get as much power as possible, for mobile phone users is significant.

Why does the Android phone charge fast?

Speaking of Android phone charging, we have to improve the company's "fast charge" (Quick Charge) technology. At present, most of the Android mobile phone manufacturers are integrated high-pass fast charging technology, as long as the Qualcomm processor is almost all support the phone, and most manufacturers are based on Quick Charge to name their own fast charge

In June, Qualcomm released the newly improved Quick Charge 4+, the new Quick Charge 4 + enhanced a number of intelligent features, including improved charging heat dissipation, 15% increase in charging speed, 30% efficiency and so on. According to Qualcomm, Quick Charge + as long as 15 minutes will be able to charge up to 50%, and extend the battery life and safety. At present, many carrying Xiaolong 835 processor Android flagship mobile phone has been equipped with the function.

For the Apple lineup, the iPhone's official charger output voltage is 5 volts, current is 1 amp, total power of 5 watts; and some fast charger output voltage of 9 volts, current 1.67 amps, the total power of 15 watts. Part of the fast charger power can even reach 20 watts, charging speed can be imagined.

Apple because there is no use of high-pass chip, so there is no fast charging function. If Apple continues to use its own series of chips in the future, it may develop fast charging technology. So far, Apple has not yet used in its chip or iPhone fast charging function.

Of course, if you want iPhone charge faster, you can use the iPad's 12-watt charger to charge the iPhone. Compared to the 5-watt iPhone charger, iPad charger in support of a larger charge current under the premise of using the iPad charger to charge the iPhone when it takes time to use the iPhone charger to charge the iPhone to be shorter.

Previously we found that the two iPhone 6s from the power of 0% to start charging, one of which is using a 5-watt iPhone charger, the other one is a 12-watt iPad charger, the results of the iPad charger less than the iPhone charger 13 minutes to fill the device. 5 watt charger takes about 2 hours 41 minutes will be an iPhone 6s full of electricity. Only compared to Android fast charging, iPhone, the charge rate is still a lot slower.

Future iPhone or equipped with fast charging function

According to Keiji Securities analyst Guo Ming 錤 in May this year, a report released that Apple will soon release several new iPhone will be equipped with fast charging function. Of course, this means that you want to use this practical function you have to buy a new iPhone.
