Is a fast charger destroying or improving the battery?
Smartphone batteries have improved in recent years. Phone cases – θήκες κινητών – allow fast charging and protect your phone all the time! At the same time, scientists have analysed in more detail how they charge, what conditions cause the ageing of their chemicals and which do not.
They have found the best ways to manage charging and discharging. This is the reason, after all, that in recent years we have mobile phones with fast charge.
The first thing you need to know is that lithium-ion (li-ion) batteries are not going to change in the near future – unless there are cosmopolitan changes – as they have not changed in years. The basic technology is the same, with minimal minor changes.
Fast-charge does not damage the battery
Research on charging lithium-ion batteries has shown that fast charging does not damage batteries if charging properly. All smartphones that support fast-charge, adjust the charging process so that there is no problem.
Lithium-ion batteries can charge very quickly when they are empty. This allows the application of high voltage up to 50 – 70% (depending on the model) of the charger, without any problems for the battery. This is the first phase of charging, which is done very quickly. For example, Samsung promises to charge from zero to 70% in half an hour, while Apple advertises 50% in the same year.
The second phase of charging should be done much more slowly and carefully. The charging systems constantly monitor the voltage, temperature and intensity of the current in the battery and adjust the supply accordingly, so as not to damage the battery. This is why the last 20-30% of charging can take much longer.
You can’t overcharge the battery
The charging process is controlled by special circuits of the smartphone itself. Even if you have it constantly connected to the charger, the charge management circuits are not going to charge the battery beyond 100% and simply turn off the power supply before the battery is over-charged.
In fact, Apple has added an additional feature, Optimized Battery Charging, which stops charging to 80% if you have a habit of constantly leaving the device connected to the charger day and night, for even greater security and long battery life.
You do not need to drain the battery
Once upon a time, technicians suggested that you let the battery drain completely. This is no longer needed. To be precise, not only is it not necessary, but it is best not to do it often. Most smartphones turn off the device long before the charge reaches zero, to protect the battery. The reason is that, at zero, the battery produces chemical reactions that can reduce its lifespan.
Away from high temperatures
This is a real problem. Keep the battery cool to keep your head calm. High temperatures are the only real enemy of the battery.
Chargers and cables do not damage the battery
Yes, you can use any charger you have available – as long as it’s not monkey or problematic. No mobile phone requires its own charger. It may not charge as fast as another manufacturer’s charger, but it’s definitely not going to damage the battery.
Obviously, the best practice is to use the charger and the cable that came with the device, but that’s for charging speed. You can use chargers and cables from other devices, as long as you are sure that the cables are in good condition and the chargers are genuine, like the ones here that you will find in Thikishop.gr stores. You do not have to take off you phone case, fast charging permits charging with the case.
