the Fast charging does not degrade smartphone batteries any more than slow charging. It also emerged in a two-year test that debunks one of the most common myths about the technology.
Fast charging helps reduce battery charging times, however During use, a lot of heat is generated, which affects this component. This is because smartphone batteries are mainly made of lithium ions, which are very sensitive to temperature changes, and degrade when the temperature is high.
That is, rapid charging, by generating more heat, damages the battery, causing it to lose its capacity over time. Therefore, It is usually recommended to use a slower 5W chargerIf you are going to connect the mobile phone to power for a long time or Do not charge the battery more than 80 percent Do not leave it completely empty before charging it again.
However, tech experts from YouTube channel HXT Studio have put this fact to the test An analysis spanning over two years and covering 40 phones, specifically the iPhone 12 and iQOO 7 models..
Tests include different loading formats: One fast chargewith loaded 20W models and other 120W models; Another with slow charging5W and 18W; The third group uploaded Fast charging 30 percent and 80 percent; and a control group that did not charge for six months.
These experts measured the charging capacity of smartphones before and after the test, and found this after 500 charging cycles The degradation between iPhones in the slow charging and fast charging groups was similarThe first lost 11.8 percent of capacity and the second lost 12.3 percent, i.e. a difference of 0.5 percent. In the Android system, slow-charging phones declined by 8.8 percent, while fast-charging phones declined by 8.5 percent, a difference of 0.3 percent.
In itIn the test with only 50 percent charge (between 30-80 percent), the degradation detected was lessOn iPhone, 4 percent of fast charging capacity, and 6 percent on Android, a difference between the two operating systems of 2.5 percent.
These tests led them to confirm this Fast charging does not degrade the battery any more than slow chargingand Keeping charge levels between 30 and 80 percent helps maintain qualityBut this does not prevent complete deterioration.
On the other hand, they conducted another test to clarify If the battery is 100 percent charged it also causes damage. Here, they divided the cell phones into three groups: one left at 1 percent, another at 50 percent, and a final group with the cell phones connected at 100 percent. After a week, they did not detect any changes in battery capacity.
