Maybe you should break the habit of charging your phone at night

Leaving a mobile phone on charge overnight seems obvious to be quite detrimental to it. Despite this, we continue to do it, it seems to us perhaps more comfortable than separating from it for 20 minutes in the morning, while we charge it.

Well, considering that current mid-range and high-end devices charge to 50% in about 30 minutes with a fast charger, why do we insist on leaving it eight or more hours plugged in? ?.

Let’s point out, first of all, that no, your phone doesn’t overheat or break down before leaving it connected for eight hours. It’s a myth that it really isn’t. The problem is not that it reaches 100% and continues to receive power. Once it reaches 100% battery, the power supply is automatically interrupted.

In addition, lithium-ion batteries are prepared to withstand large charge cycles without degrading.

However, it is not recommended. Why?. Basically because because the phone is still active at night (notifications, updates…) it will be constantly charging (although for very short periods of time).

Then the charging process is going to be more continuous and that is where it can overheat and consequently shorten the number of charging cycles.

Understandably, back when things took a long time to charge, an overnight charge made sense, but now things charge so fast that switching to charging 30 minutes in the morning and 30 minutes in the the afternoon makes more sense.

Technical support services recommend keeping the battery percentage between 50 and 80%. In this sense, it is a good idea to charge the smartphone for short periods of time during the day.

Finally, using the mobile while charging is not harmful per se, nor does it increase the risk of fire, nor does the battery suffers excessively (thanks to advances in technology). Yes we will notice that the device takes longer to charge, so it all depends on how rushed we are to disconnect it from the power.
