Do you still remember the days when we charged all day and all night after buying a new phone? It was for the reason that batteries at that time had a so-called memory effect and they needed to be calibrated. In other words, fully charge and fully discharge.
Modern batteries no longer need to be calibrated
Some people think that we still live in these times, but this is not true. Today, batteries are more modern, better, and above all without memory effect. So if you buy a new phone, you don't need to calibrate its battery. You simply charge it and use it.
If you plan to keep your device longer, you should definitely not forget that how to treat its battery. How to charge it, in which environment not to use the phone, etc. Is it ok to leave the battery charging all night?
Charging the battery all night is not the best solution
It's not. Just like any device that contains a modern battery, also the smartphone battery feels best when it is neither fully charged nor discharged. Charging it to 100% harms it significantly more than charging it to, for example, 80%. Smartphone manufacturers themselves say that it is ideal to keep the battery charge between 20-80 percent.
In the short term, daily top-up charging does not harm the battery very much, but after a certain time, for example after six months or a year, the first symptoms of incorrect charging may appear. You will feel it especially in the deteriorating endurance for one charge. The battery will simply lose a certain percentage of its capacity over time.
As an example, we can mention iPhones from Apple. In the iOS system, you can see an item called "battery health," which will show you the condition of your phone's battery. If the battery health is at 80%, in theory you will get as much battery life after a full charge as you would get if you bought a new phone and only charged it to 80%.
No, you cannot overcharge the battery
If you are worried that long charging can "overcharge" the battery, you can be sure that this will not happen. Every single smartphone or other device equipped with a battery is protected against this. It works simply. When the battery is charged to full capacity, charging is automatically turned off. Even if the cable from the charger is still connected.
Charging the phone's battery to 100% does not harm it so much if you start using it immediately after charging (which actually starts to slowly lose energy). Therefore, manufacturers install a function called in their models optimized charging. Thanks to it, the phone slowly learns your habits, and when it knows that you regularly get up at 7:00 a.m., the battery will only charge up to 80% at night and will be fully charged just before you get up.
The number of charging cycles is important
Even more than a full charge, the battery is completely discharged. The worst possible scenario is that you completely drain and fully charge your phone every day. Battery life is given in charge cycles, they should handle at least 500. The larger the battery, the more charging cycles it should handle before it becomes unusable.
One full charge equals one charge cycle. Therefore, it is recommended to charge the battery several times during the day, rather than letting it completely discharge. It is most ideal to keep the battery charge constantly between 20-80%. Of course, this is not always possible. The phone should still be a tool that makes our lives easier, so sticking to this rule at all costs is, so to speak, nonsense. But if possible, definitely do not discharge your smartphone to zero and do not charge it fully. Its battery will thank you with a longer lifespan.
Pay attention to the temperature
Other factors also affect battery life. One of the most important is the ambient temperature. Hot summer days are not ideal, and neither are cold winter mornings. Long-term exposure to adverse temperatures can result in faster battery degradation, that is, a significant weakening of her endurance.
Heat is also generated during charging. Today's smartphones can already be charged quite quickly. The faster the charging, the higher the temperature. Fast charging, for example, in direct sunlight is definitely not good for the battery. Of course, smartphones constantly monitor the temperature of the components and reduce the excessively high temperature during charging by simply reducing the charging power. For example, try to compare how quickly your phone charges in direct sunlight and at home in the shade. It will definitely be faster at home.
Use a quality charger
You should also not forget to use a quality charger. Ideally, the one you received in the package with the phone. If you are buying a new charger, rather choose a model from a proven manufacturer, despite the fact that it can be a bit more expensive.
