Play while recharging the phone will hurt the lithium battery

Someone asked on the Internet, "is it bad for your battery to use it while charging? Why can you play with your laptop while charging while your phone is not?" The following answers come from lithium battery practitioners.

It doesn't really matter if you can take the battery out and continue to use it. Battery floating to the damage to the battery life, not necessarily the cycle life of lower than the recycled more serious, today we in the industry there is still no way for quantitative analysis, including floating experiment, high temperature accelerated ageing life no current national standard or standard, part of the factory and doing the related research at colleges and universities, to little effect.

My approach is still to use it however I want.

Consumer electronics, the battery is consumption, but really now cost is very low, I am playing the lithium iron phosphate, and consumer electronics ternary lithium there's a difference, but the lithium iron phosphate battery energy storage industry average now within 5 RMB/Wh (including 4-10 years warranty), electric car industry base in 6 RMB/Wh (usually 3 years warranty), consumer electronics, because of its capacity and shipments, and don't need to greatly improve the relationship between the yield with group, cost is much lower than the above two industries. So the millet power supply 10Ah, namely 37Wh, is only sold for 69, isn't it? Similarly, mobile phone battery, android series, mainstream 3Ah, 10Wh or so, also dozens of pieces.

Dachang heart black, accessories is a big piece of profit, but in fact, one is not expensive. A year to change a battery, injury blood? Besides, cell phones die in a year.

Note, however, that lithium batteries generate more heat when charged than when discharged at the same current. Many phones get hot during charging, and that's where it all comes from. So I will use mobile phones to play big games, when charging of CPU and other components of fever is very severe, the measured part when the CPU capacity will reach 40 ℃ temperature. Play two add up, when charging mobile phone battery temperature can easily exceed 70 ℃ or higher. Under the condition of high temperature and full charge, the electrolyte of lithium battery will have irreversible side reaction, which will cause the overall capacity attenuation of the battery. And that's not the worst part.

Under such a high temperature outside the cell phone battery, non-good product battery encountered internal gas production, and then bulging, and aluminum shell and plastic shell battery often too much internal stress BOOM, no explosion, mobile phone will also appear deformation. Probability is not high, so many batteries in China, the case of explosion is far less than the car accident. But no one wants to win the lottery.
