Charging your phone day and night – What should you watch out for?

  • I bet you want the vast majority of you charging your phone overnight
  • However, there is a myth among users that it is dangerous for the battery
  • What about night charging really and can it destroy the battery?

Charge with the original adapter

First of all – smartphones have quite classic lithium-ion batteries. These have a certain lifespan and degrade over time. You will not change the aging process of the battery, you can only slow down its failure. You can do this even if you do not expose your phone to extreme temperatures, humidity or cold. And last but not least, gentle charging.

And you hear me right, it doesn’t matter when you charge your phone – whether day or night – but rather how. As much as it sounds like a textbook of manufacturers, always use an original charger – or at least a charger with the same power as the original one. By charging your iPhone with a charger from Huawei with a power of up to 40 W, you risk destroying the battery faster.

Also pay close attention to damaged chargers and cables. Surely you know this – you need to charge your mobile phone, but the cable looks as if it was used for many activities other than recharging the phone and flashes from the battery (exaggeration) or a bad smell of burnt plastic (common reality, unfortunately). Even if you definitely don’t want to go to the store and sacrifice five hundred for a new charger, you better do it. When I overdo it with the parallel, the energy in the lying moldy mattress doesn’t replenish you well either.

The lower the power, the healthier the charging

Another piece of advice connects with the first one. Always charge the phone with the maximum prescribed power. However, there are also phones on the market that support high-speed charging, for example with a power of 65 W. This is definitely a big effort for the battery, because you can also charge a laptop with such an adapter. Some manufacturers circumvent the risk of destroying the battery by inserting two split batteries into the body.

Personally, I most often charge phones wirelessly, which, with a few exceptions, rapidly reduces charging power and saves much more battery power. With the cable, for example, such a Samsung or iPhone can get up to 25 W, while wirelessly barely 15 W. There are many myths and hoaxes about wireless charging of Qi – we tried it in the newsroom.

Does charging overnight destroy the phone’s battery?

We come to the main question – does overnight charging have a negative effect on the phone’s battery? I’ll add my own experience at the beginning, because I don’t charge the phone overnight. But it’s not for fear of destruction, but rather because I’m charging all day at work on a wireless charger, so I don’t need to charge the phone all day and all night.

But even if I wanted to, it wouldn’t hurt the phone. Today’s smartphones don’t call themselves “smart” for nothing. Most current mobile phones with a modern operating system have quite sophisticated energy management and know very well how much energy to receive and when.

Phones are often charged overnight with only half the power, for example only up to 80% (which is the healthiest for li-ion batteries – editor’s note) and before the alarm rings, they are charged to 100%. In any case, you don’t have to worry about the phone charging in the middle of the night and then the battery so-called overcharging. Smartphones are smart devices that can already cope perfectly with more frequent charging.
