Smartphone charging process is performed by the collaboration of three parts, namely: cell phone power adapter or cell phone charger, data cable, mobile phone. Subjective factors including the phone itself,cell phone power adapter or phone charger, and a data line and objective factors including the weather and how to use the cell phone are the key factors impacting on the rate of charging the phone.
The larger the capacity of the mobile phone battery, the longer the charge time
We shall firstly figure out how to calculate the charging time before what make a impact on the speed of charging the phone, the charging time can be calculated with a simple formula: Charging time = factor (typically greater than 1) × battery capacity (mAh) / charging current (mA) . That is the Large-capacity cell phone battery charging time corresponding to the long charging time when the charge current is constant; similarly, small capacity battery is corresponding to a short charging time.
Thus, it is necessary to charge more prolonged electricity for our phones in order to meet the needs of using mobile phones for a long time when charging current is kept constant as the mobile phone manufacturers increase capacity .
Moreover, in practice, the current is based on the servis mobilnih telefona novi sad load (ie cell phones) connected. Just within the limits of its resources,the cell phone charger can provide much current the phone needs. If the current required by the phone exceeds the current limit the cell phone charger can provide, then the cell phone charger would have been outputting the maximum current. So when the battery capacity is the same, the charging time will be faster as the current the phone itself can carry increases.
Power adapter charging specifications affect the charging rate
The output voltage of most brand mobile phone standard charger is currently standard 5V, but the output current which would be equipped with by the manufacturers depending on the battery capacity are different. Assuming the assumptions voltage is same , the difference between 0.5A, 1A and 2A cell phone charger just like bicycle single-lane, two-lane and four-lane highway- a charged battery is also be doubled as current is per doubling over the same time. So for iPhone charger with a maximum only 1A output charging iPad and 2A original charger charging iPad, the former theory charging time is 2.1 times the latter.
Therefore, when charging the cell phone, you should try to choose the original cell phone charger or those whose output current is not less than the original standard charger in order to ensure that the phone’s charging speed is fast enough.
The data line with poor quality is the”murderer” slowing the charging timeGenerally it is too difficult to identify a clear difference from the appearance of the data lines, so all the interface mixed like a routine, but the current provided by different data lines may be different.
Many low-cost data line looks very thick, but its internal core is actually pretty thin, or those meant to be made by pure copper wire replaced by aluminum wire are knock offs. In addition, poor quality data cable connector contact material and welding may be abnormal, these problems will lead to increased resistance, standard data line resistance should be 0.5 ohms, while the poor line may reach 3 to 6 ohms, the charging efficiency decline definitely in 6 fold to 12-fold.
