There are many questions about the good use of our mobile phone battery. One of the most common, however, is whether it is ultimately to leave our smartphone in the socket to charge all night while we sleep.
What most experts agree on is the fact that our mobile phones are smart enough to understand when their battery has reached 100%. Therefore, no, there is no risk of them being charged more than is necessary or needed.
When the battery reaches 100%, then charging stops automatically. The new devices to reach 100% of their battery need one, at most two hours.
But what happens when you put your phone on charge just before you sleep, so you can find it with a full battery in the morning?
When your smartphone reaches 100% of its battery, as we said, it stops charging. As time passes, its battery drops to 99% and starts charging again automatically to get back to 100%. And that keeps happening until you unplug it, which certainly affects your battery life.
Every time you leave it all night charging, your cell phone is getting warmer. The right thing to do in this case is to take out its protective case so you can drop the temperature. Also, it would be nice not to have it beside you, for example on the bedside cabinet or (under no circumstances) under your pillow.
Last but not least, the cable with which you charge your cellphone is worth a look. If it is not the official cable of your mobile company or it has a problem (for example it has been cut off at one end), then you may be doing great harm to your smartphone battery.
