why you shouldn't charge your smartphone overnight ??

Here's why:

   Most of people leave his phone plugged in to the charger overnight? It turns out, this is one habit you need to stop it now.

   Unless of course, you don't intend to hold on to your phone for more than two years. Studies point to the fact that charging your phones overnight can result in extensive internal damage to your phone. Frequent charging takes a toll on lithium-ion batteries in your phones.


Is there a solution?:

If you're intent on preserving a lithium-ion battery beyond the lifetime of the typical phone or tablet, Zeine suggested using a charger meant for a less powerful device, though he couldn't guarantee that it would work. "For example, if you used an iPhone charger on an iPad Pro, it's going to charge very slowly," Zeine said. "If the electronics are right, they can actually preserve the battery because you're always charging it slowly."

People looking to preserve their batteries should make sure their phones don't become overheated, Campos advised, because high temperatures further excite the lithium-ion in batteries, leading to even quicker deterioration. Apple's website says temperatures above 35 degrees Celsius can "permanently damage battery capacity."
