Your phone battery is broken after charging overnight? Don't be fooled again

Many people have the habit of charging their phones overnight. After all, we use our phones for everything nowadays, and it would be embarrassing if the phone doesn’t have enough battery the next day.

But some people say that charging your phone overnight will accelerate battery loss and make the phone break down faster. Is this true?

01 Is there any harm in charging your phone overnight? Let me first state the conclusion: as long as your charger is produced by a regular brand, there will generally be no major problems.

In fact, today's mobile phone chargers are already very smart, they can do dynamic charging:

When the phone's battery is low, the charging speed is very fast; when the phone's battery reaches about 75%, it will automatically maintain a constant voltage of about 5V for charging.

In other words, the more power a phone has, the smaller the charging current will be. This phenomenon is also called "trickle" charging.

We take the charging process of iPhone 12 as an example to show: when the power increases, the charging current of the phone gradually decreases.

This charging mode can protect the phone from the impact of high voltage and current on the phone's circuit board and battery when the phone is about to be fully charged. It is a reliable way to protect the battery.

So you really don’t have to worry too much about charging your phone overnight.

02 In this case, you cannot charge overnight. Of course, the above applies to original or regular brand chargers.

If you are using a no-name charger, such as the one that costs 9.9 yuan with free shipping...then stop it!!!

This kind of low-cost charger cuts corners in its internal structure and components. When you use it to charge your phone, even if the battery is fully charged, there will still be a micro-current flowing through it. These extra micro-currents may not cause any damage in the short term, but for the phone, it is tantamount to chronic suicide.

Over time, the components of the mobile phone will age rapidly, resulting in the charger breaking down and the mobile phone battery also breaking down.

Moreover, low-priced, no-name brand chargers are crudely made, use poor materials, and may even use non-flame-retardant casings.

When we were testing mobile phone chargers before, we bought a low-priced imitation Apple charger that used a non-flame-retardant shell. When we conducted a flame retardant test, its flame retardant effect was very poor, and it continued to burn after the flame left.

The test video is as follows:

(This is a professional laboratory operation, please do not imitate)

The safety hazard here is huge. If the charger short-circuit and catches fire during use, it can easily cause a home fire.

Many news reports of chargers spontaneously catching fire are simply because people just bought a cheap charger.

03 Still worried? You can consider changing the charger. In fact, for most of us, the reason why we charge our phones overnight is because:

My phone was only 50% charged before going to bed. If I unplug it, it won't be enough for the next day; if I wait for it to be fully charged, it will take a while.

You can't... set an alarm and get up in the middle of the night to unplug your phone, right?

In fact, this situation is easy to solve. Just change to a fast charging charger with a faster charging speed.

Finally, let me summarize for everyone: original or regular brand chargers can be used for charging overnight, and the damage they cause to the phone is not as great as you think.

If it is a cheap brand-name charger, then I suggest you replace it as soon as possible. This kind of charger not only damages the phone, but also poses certain safety risks.
