I believe that if you turn it off or switch to airplane mode during charging, your smartphone can charge faster. Sounds logical, right? In the on state, any device must consume energy, which will inevitably lead to an increase in charging time.
But is it true?
In order to test this, we conducted our own experiments. Because it uses a USB tester, it can connect to a computer and create a chart to charge. It helps to understand what happens when your smartphone is turned on or off.
The guinea pigs are Tecno Camon 11s, Yandex.Telephone and Turbo X Dream 4G smartphones. These are low-end models, but it's clear that for more expensive smartphones, the results will have the same characteristics, for example, the TheUnlockr youtube channel experience.
For the purity of the experiment, all tests were performed using the same power supply and the same USB cable was used in all cases.
Should I use a smartphone when charging?
First, take the smartphone Tecno Camon 11s. The smartphone uses the Mediatek MT6761 processor with a battery capacity of 3750 mAh.
The figure below shows that the maximum current during shutdown of the device is approximately 1.72 amps and the smartphone is fully charged in 2 hours and 43 minutes.
The next stage is the current measurement when charging the included equipment. Here, we see that the maximum current increases to 1,755 A, and the chart itself becomes even larger. This indicates that during the entire charging process, the smartphone attempts to compensate for the power consumption required for the operation of various mobile device modules. This is achieved by increasing the current supply, while the maximum value of the voltage is almost unchanged.
In addition, each time the screen is turned on, the smartphone further increases the received current intensity, which is expressed in the form of a sharp increase in performance on the chart. But when the display is turned on, the charging speed does decrease, especially when heavy games or applications are running, and some low-end smartphones start to discharge even when performing complex tasks, regardless of whether the charger is connected.
Conclusion: In a simple task, the smartphone can compensate for power consumption. But not always.
Do I need to turn off my smartphone when charging?
For the second test, we placed Yandex.Phone on an eight-core Qualcomm Snapdragon 630 and 3050 mAh battery (supporting fast charging). Like many smartphones, his function is to charge for a period of time after the percentage indicator reaches 100% - in the case of Yandex.Telephone, it reaches 25 minutes.
By the way. You shouldn't trust the percentage of mobile devices when they are turned off and on, but on the other hand, full charging, such as 0% discharge, is harmful to the battery (except for some cases mentioned later), so the percentage of the display can be taken care of by the user. To explain. By the way, due to the low level of charge, the battery has a reserve after turning off the device - it is foolish to make a device that uses 100% battery capacity.
Therefore, the disabled Yandex.Telephone charges within 2 hours and 23 minutes. The maximum charging current is 2.6 amps.
Surprisingly, when the Yandex.Telephone is turned off, a higher voltage is applied precisely, but if the current becomes smaller, no change in charging time is observed as a result.
Conclusion: Turning off the smartphone during charging does not affect it.
Should I put my smartphone in flight mode during charging?
Is it possible to trick a mobile device, charge it, but enable airplane mode? Does it reduce self-discharge and reduce the time required for full discharge?
Using an example of another smartphone, the Turbo X Dream 4G (MediaTek MT6739, 4000 mAh battery capacity), you can ensure that there is no difference in charging in airplane mode compared to other charging options. It takes about 4 hours and 2 minutes for Turbo to fully charge.
Conclusion: The idea of charging a smartphone in flight mode is a myth.
Do I need to charge my new smartphone under the 3 by 3 plan?
Another popular argument is that any new battery requires three full charge and subsequent discharge cycles. However, there is a view that modern batteries do not require such an action. So who is right?
For example, use the Turbo X Dream 4G smartphone again. During the first discharge and subsequent charging of the battery, the percentage indicator was found to be malfunctioning, which is why the device was turned off at 7% charge. In addition, when using the USB tester to measure battery capacity, the number displayed is 3506 mAh, while the manufacturer shows 4000 mAh.
Conclusion: Sometimes the battery capacity does not match the specified value. But this is normal.
to sum up
Creatures recover faster in dreams, but there is no reason to turn off your smartphone to reduce charging time. The charging time is actually increased only when the display of the smartphone is always on.
Modern mobile technology automatically increases the receiving current to compensate for the discharge when the device is not turned off. The difference is about a few minutes and can be called an error during testing.
If the smartphone shows 100% charging, this does not mean it is fully charged - you must consider this if you want to check the charging time of your device.
