I believe that everyone has encountered the iphone charging when the charger fever, sometimes even hot. What the hell is going on here? How to solve it? Why the iphone charger gets hot First of all, when the iphone is charging, the charger fever is normal, which is related to the current intensity of the

The latest kernel (v3.5) currently does not support the overall USB charger solution. The USB charger solution discussed here only refers to the software solution, that is, the charger detection needs to be performed by software intervention (such as reading the usb phy register), and the battery charging value needs to be set by the software according to differe

Apple defines 3 charging currents for the charger, which are 0.5a/1a/2.1a. This is achieved by a combination of 3 different resistors. When an Apple device ipad,iphone,ipod the USB port charger, it detects the voltage on the USB d+ and D-to determine the output current of the charger, and then combines its own required current to determine the specific input curr

On June 23, June 4, the George Institute of Technology Security research team just found a way to write information to iOS devices through a modified charger. They said the improved Charger could upload any data to the device within one minute after the iOS device is connected. The researchers said that all iOS users are at this risk, so that illegal operations do not require any user interaction. Hackers c

The charger radiates the equivalent of high-voltage electricityHuman body and charger or transformer should maintain a distance of more than half a meter, especially mobile phone charger, otherwise long time close contact, easy to increase smokers cancer risk.A recent survey by the Israeli Ministry of the Environment found that many Israelis are accustomed to put

Samsung original Charger in the design, the use of strict quality control process to ensure that the product performance optimization, its service life has a reliable guarantee. The use of non-original parts have input and output voltage instability, poor compatibility, and the work of a large difference, easy to the battery and machine damage, if the use of a non-original charger caused by the machine or b

question: Apple Iphone/ipad original charger lost to find another charger to replace the line it? Is there a compatible brand recommendation, how much is about? Answer: in principle, do not recommend the use of a non-original charger, because even if there is a compatible brand charger, due to voltage, current and oth

No matter how small the Internet device requires a battery or power cord. But it will soon change. This technology is about to be commercialized by allowing the device to ingest electricity from the surrounding TV, radio, cell phone, or Wi-Fi signal to work and communicate. BreakthroughA new wireless device that can power itself and communicate with neighboring radio signals, such as Wi-Fi.MeaningInternet devices will get rid of the battery and power cord and open up a lot of new appl

Current The size of the current will directly affect the speed of cell phone charging, we can not blindly pursue a large current. Cell phone batteries are usually labeled XX MA, such as Samsung I9300 battery capacity is: 2100mAh. Then look at Samsung i9300 original charger parameters: 5v-1.0a, Output current is 1 A, that is 1000mAh. The battery 2100mah÷1000mah about a little over 1 hours of charging time. 　　Voltage As for the voltag

Panasonic BQ-830 charger is produced by Panasonic Company is a kind of designed for Ni MH rechargeable battery a kind of high-grade charger, Small PCB Board actually has 7 IC, work more fine, the principle is to convert the external 5 V or 12 V Direct current through the internal switch power supply to output high current pulse current, for the Ni-MH battery pulse charging, with battery power detection, ful

Is this: The Charger plug in the power input is 220v because the charger is a transformer through the coil turns the 220v buck and then a series of steady flow and so on mobile phone charging according to the need for charging voltage is generally 3.7~4.2v so the output voltage is 3.7~4.2v Electricity is based on the power of electrical appliances like to charge the phone general output current in 500~800ma

If you use an existing old charger, you may not be able to provide sufficient charging energy for the device. As a result, your device may appear to be unable to recharge or take longer than usual to give the battery full power.(* reference: A charger with the same output current as the current value required for your device is the best choice.) For example: Galaxy s2:0.7a, Galaxy S3:1a, Galaxy s4:2a, note

The main tasks of the pre-bringup phase of a smartphone or tablet charger module are as follows:1. Boot is normal. MTK platform needs to turn off the first battery detection function, because the MTK platform of the pmic baton pin on the one hand is to detect the temperature of the battery on the other hand or to detect whether the battery is in place, the first boot does not pick up the battery may cause the machine can not be opened. 2.
