Should I discharge the battery before charging

Charging the cell phone correctly: Users often get it 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 But many of these charging legends are simply wrong - or at least outdated.

Discharge the battery to full capacity several times if possible - only use the power supply unit supplied, otherwise it will break? Far from it, both supposed wisdoms belong in the realm of outdated battery myths. An overview.

1. The memory effect

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

2. Wrong power supplies

There is no wrong power supply, at least not with current smartphones that are charged via USB cable. Upstream charging electronics only allow a defined flow of energy through here. 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 takes longer with a third-party charger. There is also another important exception: cheap chargers from China, 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 dates back to the days 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 specialist 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 30 to 80 percent. Several shorter charging processes can even be better for the battery in the long run than charging up to 100 percent each time.
