In the best case, a cell phone battery should last a whole day from the morning. Many therefore charge the battery overnight, but this has consequences.
Kassel - Before going to bed, quickly check the latest messages and then simply connect your mobile phone to the charging cable. This is what the process looks like for many people just before falling asleep. The advantage: The mobile phone is charged in the morning and ready for use. But falling asleep next to the charging mobile phone can not only be detrimental to the quality of sleep.
This is because charging at night can also cause considerable damage to the battery. As a result, the battery does not last as long as before, despite being fully charged. The culprit is a certain mechanism of the mobile phone. So if you want to have a long-lasting battery, there are a few tips to follow.

Charging the phone at night damages the battery and poses further dangers
Often, the mobile phone is charged overnight for seven hours or more. But the battery only needs a few hours to be full again. To ensure that the mobile phone is not damaged, a mechanism ensures that the current flow is interrupted as soon as it is fully charged, according to Funke Mediengruppe. Thus, the mobile phone is no longer supplied with Storm. So a discharge occurs. But as soon as the battery is only 99 percent charged, the charging process begins again. As a result, the mobile phone is alternately charged and discharged all night long. This process ultimately causes damage to the battery - especially older mobile phones.
Charging for hours at night is also not exactly energy-saving. If the laptop or tablet is then permanently charged, it can quickly become expensive. But heat can also be harmful. If the mobile phone is charged for a long time, the battery heats up. The resulting heat can cause the battery to break down more quickly. In some cases, overheating may also occur. The mobile phone should then no longer be used, as the battery can also ignite according to Ökotest.
If the battery is exposed to extremely high temperatures, a short circuit or a thermal reaction can Chip.de occur, according to the technology consumer portal. In this case, it will be especially dangerous: depending on the materials used and the design of the device, there is a risk of explosion. This can also happen with a power bank.
This is what you should keep in mind when charging the mobile phone battery
The Ökotest advises so-called disciplined charging and unloading. What is meant by this is that the battery should never be completely discharged, but also not overcharged, as is the case with nightly charging. According to TÜV, the charge level should always be between 30 percent and 70 percent. If you want to enjoy your mobile phone battery in the long term, you should therefore observe the following tips:
- Charge the battery with the manufacturer's original charging cable
- Battery should never be completely empty and neverovercharged
- Optimum charge level is between 30 percent and 70 percent
- Batteries protect against: heat, frost, moisture and high humidity
- Battery may be damaged by dropping

Fast charging can also damage the cell phone battery
In addition, tests by the electricity provider Verivox have shown that fast charging can also damage the battery in the long run. The battery capacity is said to last five times longer with normal charging than with permanent fast charging. Impatience is thus punished by decreasing battery performance.
If you want to make sure you don't damage the battery, you can simply turn off the phone at night instead of charging it. In addition to the positive effects on the battery, turning off the cell phone overnight can also lead to a better quality of sleep due to a lack of radiation, according to consumer advocates. (mima)
