Users often get this wrong when charging

Many users think that they are very familiar with batteries in electrical appliances. But many of these charging legends are simply wrong – or at least outdated.

Failure to fully charge it hurts battery pack – But also plugging in and unplugging too often? Far from it, both supposed wisdoms belong in the realm of outdated battery myths. An overview.

1. The Memory Effect

It is still often said that a battery should always be empty before it is charged. However, this no longer applies to smartphone batteries, as they have lithium-ion batteries. Completely draining these batteries is actually detrimental to their service life. Nickel-cadmium batteries, on the other hand, can lose capacity in the long term if they are charged early – in smarter technology but these are only found extremely rarely.

2. Wrong power supplies

There is no wrong power supply, at least not with current ones Smartphonesthat are charged via USB cable. Upstream charging electronics only allow a defined flow of energy through. So you can use all suitable power supplies and also charge iPhones with Android chargers. However, not all smartphones support the same fast charging technologies. If in doubt, it will take longer with a third-party charger. There is also another, important exception: Cheap China chargers, such as those found in web shops or on Ebay, should not be used. They often do not meet European safety standards. So you should at least make sure to find a CE mark on the device. However, the power supplies are not really tested. The GS seal is much safer here; devices are actually tested for their safety here.

3. Charge properly the first time

The first charging process for a new smartphone doesn’t have to be particularly long, and you don’t have to fully charge the device either. This widespread view stems from the time of older battery technologies, but modern lithium-ion batteries do not get any better performance from it. So you can fully charge it the first time – but you don’t have to.

4. Too frequent plugging and unplugging damages the battery

Not true either. According to the trade magazine “Connect”, batteries only last a certain number of charging cycles. A charging cycle can also consist of several charging processes.

5. Always charge fully

You don’t have to. In fact, the perfect charge level for a battery is between 30 and 70 percent. Several short charging processes can even be better for the battery in the long run than charging up to 100 percent each time.
