Why Is My Phone Charging Backwards? | ZONSAN

1, the battery low temperature, poor quality wire, poor quality USB interface will cause the phone back charging.

2, the phone charging environment needs to be above 10 degrees Celsius, to use the original charger charging, do not use the computer's USB interface charging, because the USB2, 0 current is only 500 mA, if the USB interface and wire is inferior, the voltage and current is not guaranteed, so there will be the phone charging back.

It should be noted that the above reason analysis applies to all brands of cell phones. For example, I am often asked “why is my iphone charging backwards”. The answer is the same.

what to do if your phone is charging backwards

1, Please use a regular cell phone charger for charging.

2, Also please keep the charging environment above 10 degrees Celsius.

Will cell phone charging slow down in winter?

Yes. The reasons are as follows:

1, the ideal working temperature of the battery is between 15 degrees Celsius 40 degrees Celsius. In low temperature conditions, the internal chemical reaction activity of lithium-ion batteries is reduced, resulting in slower charging and lower available capacity.

2, in order to protect the phone battery, the system is set up to protect the low temperature. In low-temperature conditions will automatically reduce the charging speed and charging limit power; in the case of lower temperatures, stop charging, and the corresponding prompt message.

Will the phone explode if it is charged continuously?

1, generally speaking, cell phones using qualified chargers for a long time charging is no danger of explosion.

2, now the phone is a smartphone, the previous phone is not long time charging, so the battery is really easy to blow, but now the phone is very safe in charging, and there is an automatic power off function, smart phones have a pmu, which is the management of the battery system, simply put is the pmu monitoring the phone is not charged, you connect the power after he will put current into the battery, when it detects that the phone is fully charged, he will close the current channel, when you have not been using the phone, the phone will also have some internal power consumption components, when the battery is consumed some, pmu again open the current channel, full and will close.

3, most of the exploding cell phones, are using the cottage charger charging. Cottage chargers generally do not retain the complete filter circuit. Transformer windings and output interfaces will not do complete shielding, so the danger and reliability is very problematic.
