Charging the battery correctly
Charging cable into the socket and the other end into the smartphone - that's how simple the power supply of a smartphone battery is in theory. In practice, however, you can make a lot of mistakes. None of them will kill your smartphone, but the service life of the battery can be considerably shortened by permanently incorrect handling.
Battery charging error
Charging too often
We understand that a battery that is only half full makes you feel queasy when you leave the house. However, you should not be tempted to constantly plug in your smartphone so that you can relax when you are out and about. Many short charging cycles are much worse than one long charging cycle.
Charging overnight
This point is inevitably related to point 2 of the "DOs". If you charge your smartphone overnight, more power is pumped into the energy storage than is effectively necessary. Better to charge it an hour before going to bed and then again in the afternoon of the following day if necessary.
Disregard charging standards
There is a good reason why the various manufacturers still include their own charging plugs in the packaging: fast chargers charge with far more than two amps, but not every smartphone can handle that. It is best to use only the original charger.
Battery charging tips
Observe extremes
The smartphone battery should neither fall below 20 percent residual capacity nor be kept constantly at over 80 percent. Of course, a full battery soothes the conscience, but a constantly full state is not particularly healthy for the component itself. The best thing to do is to plug the device in at 20 to 25 per cent and unplug it again at around 80 per cent. In general, however, you should try not to interrupt the charging process; this is also not recommended. You can see how the battery charge level is changing in the settings of your device, usually under "Battery" or "Device maintenance".
Power off when battery is full
When the battery is full, you should unplug the device from the mains. This is not always easy, as you are not watching the battery being charged bit by bit. We recommend buying a smart socket that switches off as soon as the smartphone is charged. Set the socket to supply power for two hours - this should sufficiently fill the battery, but you don't run the risk of it continuing to charge for hours.
Keep a few percent
If the battery has dropped below 20 per cent, hang your smartphone from the socket with a clear conscience. It has been proven that a completely empty battery is worse for the life span than a battery that is consistently recharged at a few percent. So make sure that there is always a few percent left of the battery.
