What exactly making impact on iPhone charging rate

Almost we have to charge the iPhone every day,we certainly hope that charging rate is sooner, unfortunately, the charging speed is sometimes getting slower and slower, what exactly making impact on our iPhone charging rate?
NO.1 the charging temperature
The temperature is the main factor easily overlooked. At extremely low or hot temperatures, low temperature protection mechanism will lead to that the lithium battery material does not chemically react, that’s why the iPhone can not be charged or charging speed slows down. Please try to charge the iPhone At 15~25℃.
NO.2 unpaired iPhone USB charging adapter and iPhone USB charging cable
Please do use original USB charging adapter and USB charging cable with official configuration pairing iPhone or tablet accordingly,if you use the iPhone USB adapter to charge iPad, you’ll find the charging speed is pretty slow.Take the iPhone 6 for example,please use the iPhone 6 USB charging cable and USB charging adapter to charge it.
The current USB charging cables support varies for versions of iPhone. If charging slow, it is likely that you do not pick the right iPhone charging cable, please mark accordingly them to distinguish different iPhone charging line.
NO.3 annoying dust
if you not clear up the iPhone USB charging cable port and iPhone charging port,the longer the lifespan of the iPhone,the more the dust accumulated,that’s why the charging rate of iPhone is getting slower and slower, timely wipe the dirt on the usb charging cable with alcohol, use a needle or toothpick to clean the iPhone charging port carefully, or the charging port is equipped with dust plugs.
NO.4 charging tip
l. the charging rate is basically fastest when the iPhone is powered off, if you do not want to shut down, the flight model is the best choice to accelerate the charging speed.
2. avoid access the iPhone to host USB port to charge.
3. avoid charging the iPhone unless the iPhone battery low battery alarms.

Dose car charger make adverse impact on iPhone

Car charger is a device used frequently, then onu mall will explain for those wondering whether car charger make adverse impact on iPhone or not.
There is substantially no adverse impact for iPhone car charger.Why?Car charger is one of auto accessories charging digital products at any time in order to facilitate vehicle owners to use. Some high-end iPhone car charger typically includes two USB ports, which can simultaneously charge two digital products. These products generally feature overload protection, short circuit protection, high voltage input protection, high temperature protection to ensure safe use to realize iPhone car charger direct charging, USB charging and triple multi-use while being charged in the car.
The voltage outputted by iPhone car charger is typically 5V transferred from 12v-24v and limiting current is 500mAh, for those knock offs without protection function, the circuit has many flaws, if the buck and current limiting circuit fails, it will lead to 12-volt direct accessing to the phone, resulting the iPhone  burned. It is recommended to use the the original iPhone car charger after car inverter volt rising to 220.
Conventional car charger powered by car battery (car 12V, trucks 24V) is widely used by a variety of portable, rechargeable handheld devices equipped with lithium battery, such as: mobile phone, PDA, GPS, etc; car charger do not only consider the actual demand (constant voltage CV, constant current CC, OVP OVP) on lithium batteries, but take into account the harsh environment of automotive batteries (transient voltage spikes, the system switching noise interference, EMI, etc.); therefore Power Management IC of car charger program must be switching power supply chip featuring with high pressure, high efficiency, high reliability, low frequency (in favor of EMI design).

iPhone charger

What exactly affects the charging speed of iPhone

iPhone charging process is performed by the collaboration of three parts, namely: iPhone power adapter or iPhone charger, data cable, iPhone. Subjective factors including the phone itself,iPhone power adapter or  iPhone charger, and a data line and objective factors including the weather and how to use the iPhone are the key factors impacting on the rate of charging the iPhone.portable-recharge-socket-for-phones--cameras--tablets--etc-with-car-charger

The larger the capacity of the iPhone 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 iPhone battery charging time corresponding to the long charging time when the charge current is constant; similarly, small capacity battery 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 iPhones for a long time when charging current is kept constant as the iPhone manufacturers increase capacity .


Moreover, in practice, the current is based on the load (ie iPhone) connected. Just within the limits of its resources,the iPhone charger can provide much current the phone needs. If the current required by the phone exceeds the current limit the iPhone 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 iPhone, you should try to choose the original iPhone 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 time
Generally 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.

Easily overlooked weather

It is because the winter is too cold that the phone unable to be fully charged or charged. Because the lithium battery most smartphone uses features with protection mechanism in extremely low temperature resulting in the deposition of metal lithium which would be no longer react chemically with substance, leading to a short circuit inside the battery, that is why the phone could not be fully charged or charging speed is very slow. When the temperature is too high, this issue will appear.

Apple said that the 22 ℃ room temperature is most beneficial to iPhone charging,so do the Android phones using the same lithium situation. When the temperature is too low, we need to remove the cell phone to the warmer environment,the cell phone would not be normally charged until the lithium battery temperature exceeds the low temperature protection threshold (iPad, laptops, etc. is generally 5 ℃, the cell phone is generally about 0 ℃), when the battery is hot, you could remove the cell phone case or place it on a cold table to increase the charging speed. Therefore, the temperature is a more important external factor making affect on the rate of phone charging, proper temperature helps improving charging speed of mobile phone.

The proper charging techniques can help increasing the charging rate

Lithium battery would start lithium battery protection when it is running out of power, the phone can not boot, the charging time is longer. Charged cell phone batteries need to wait a long time to wake up, shutdown protection function. So try not to remind charging until the battery runs out.

As we all know, various programs running consume power after the iPhone is switched on, it will naturally drag the “charge rate”. So you would better turn off the App and the phone screen. Of course, it would be able to more power if we can shut down or transferred to “flight mode”, the charging speed is even faster.

In addition, some like charging via computer USB charging port,which takes longer to charge by comparison with on the charging in the outlet. Under normal circumstances, the maximum output current of computer front USB port is only 0.5A, the charging speed is very slow. If you have to use a computer USB interface to charge, you can use the computer rear USB port because its current is more stable than the front port, the charging speed of mobile phone is relatively slightly faster.

iPhone car charger

What shall you mind when using a iPhone car charger

first of all,we have to figure out what the difference between the car charger and common charger is , the fundamental difference between them is basically the plug – car charger  plug is specifically linked with cigarette lighter in the car (usually in the cab and luggage box)
The other end of the car charger is specifically designed with the USB port  the cell phone or other digital devices can be connected to.Which data lines connected to the car charger  depends on which digital device you use.
Take the iPhone car charger for example,The iPhone car charger does not properly work unless the LED indicator lights is lighting up unless the LED indicator lights is lighting up.
Note that, do not charge the iPhone until the car engine is started! Otherwise, when the car is ignited, the reduction in voltage  of iPhone car battery will make a adversely affect on the charging effect, or even damage the car charger.
Furthermore,do not place the iPhone car charger to moisture or high temperature environments, the use of a suitable temperature is 0-45 ℃;
There will be some heat during use,be sure not exceed 60 ℃ in normal room temperature;
Since various types of iPhone are different, the charging time is inconsistent, it has nothing to do with the charging performance of car charger;
Keep away from children;
Avoid lightning;
Promptly pull the plug when the iPhone car charger is fully charged, careful not to dirty the USB interface, remove the installed car charger and put it away when not in use.
So, for safety reasons, be sure to buy the regular brand, buy genuine, inferior iPhone car charger prone to security risks. Also in the use of time, please do follow the instructions to correct method of packaging in the corresponding.
