Major Flaw Of Fast Charging | Is It Burn Your Smartphone?
Nowadays one of the most appreciating technologies in smartphones is undoubtedly a fast charging feature. Smartphone manufacturers look like they are participating in a race of making super-fast charging technology for their users. These competitions are growing day by day, and now 100 W and 125W fast charging capacity has emerged in usual smartphone devices as fast charging technology, growing are still going in the smartphone industry. The latest obligation/flaw on fast charging technology calls the BadPower, which can influence fast chargers to burn, and by that, the smartphone can get heated or also fired.
According to ‘Tencent‘, a Chinese tech giant revealed this matter throughout their research, and by a research unit of Chinese tech giant Tencent, the Xuanwu Lab published this report, possibly on 16th July this year.
LetsKnowTheFast Charging Flaw
A. NORMALLY HOW FAST CHARGERS WORK?
Though from the outside of a regular charger and a fast charger are seems like equal, but that is not actually real. Inside a fast charger, there is a special firmware that generally able to communicate with the device for arranging a charging speed basing on a particular device’s capability. In this case, a device which supports fast charging feature there a fast charger provide big loads such as 12V, 20V, or maybe more faster-charging speed, but anyhow if a device is not capable to assist the fast charging feature then usually the fast charger delivers the standard 5V of electricity.
B. KNOW HOW BAD POWER ATTACK BURN SMARTPHONES USUALLY
The firmware of fast chargers is exploited by BadPower attack, and that is the reason for parameters and tampers transmute into a higher voltage than the normal capacity of a smartphone. This is the weaken part that causes to heat up components, then make that melt, and finally may burn the device.
C. OUT OF 35, THE 18 FAST CHARGES DISCOVERED AT RISK
The team of Tencent research disclosed horrible information, they research on particular some selected 35 fast chargers from 234 models from the market are naturally get accessed by peoples, and after their research, they saw 18 models from 8 different vendors were susceptible to risk in fast charge.
The relaxing thing in this matter is, the BadPower’s weakness is fixable. Many fast chargers through updating their device’s firmware can solve this matter. According to researchers, the 18 chip vendors were not able to ship chips along with a firmware update option, and that really means still there is no path that can cure this trouble.
