How to properly charge a new phone / smartphone battery?

Imagine the situation – you purchased a new smartphone or a new battery for it. Before that, on the Internet, you somewhere saw information that the first time the battery needs to be charged according to a special algorithm. Is this really so, and if so, how to charge the device?

Indeed, if you go over forums or social networks, you can see that for the first charge you need to use a special procedure that will allow, so to speak, to “pump” the battery of a smartphone or tablet. The bottom line is that the autonomy of modern devices is small – on average, a couple of days in gentle mode, after which the device must be put on charge. If you use the device constantly, it will discharge within a few hours. How can you not remember mobile phones that could not be charged for weeks …

But we were slightly distracted from the main topic. In order for the new battery to hold the charge better, it is allegedly necessary to charge it according to a special algorithm, otherwise the battery will quickly discharge.

Common Tips

There are a lot of different instructions on the net. Here are some of them:

  • Discharge the smartphone completely, and then charge it from the network. After it is charged, do not disconnect it from the network for 2-3 hours.
  • Let the device work until it is discharged to 10%, put on charge and charge for 10-12 hours.
  • Discharge the device completely three times (to zero) and all three times charge it to 100% of the charger.

It is not surprising that users get confused, ask questions, and sometimes resort to completely unnecessary procedures. Do not rush to charge or discharge your phone or smartphone, read this article until the end!

Batteries and their varieties

There are several main types of batteries that are used in the manufacture of mobile devices:

  • Ni-Cd (Nickel Cadmium)
  • Ni-MH (nickel metal hydride)
  • Li-ion (lithium-ion)
  • Li-Pol (lithium polymer)

The first two types, namely nickel-cadmium and nickel-metal hydride batteries, were used on old push-button phones. The ones that were released many years ago and which, unlike modern smartphones, were primarily a means of communication.

These types of batteries were reliable, but they had flaws. One of them is the so-called “memory effect”, which means a reversible loss of capacity, which may also be caused by a violation of the recommended charging mode, for example, if you start recharging the battery until it is completely discharged. Over time, such batteries really require “pumping”. It was then that information appeared on the “pumping” of the battery, including for the device just bought.

But times are changing, technology is improving. If nickel-cadmium and nickel-metal hydride batteries were previously used, today lithium-ion and lithium-polymer batteries are used. They are used everywhere, including in smartphones, tablets, laptops, etc. Such batteries are characterized by high power, safety, and relatively small size. In addition, they almost completely lack the “memory effect”, which we mentioned above, and therefore they do not need any special charge cycles.

What does it mean? And this means that if your device works with a lithium-ion or lithium-polymer battery, charge it in the most usual way, without resorting to the manipulations that are described in the tips above.

However, if you still take the advice from some forum, it is unlikely that anything will change.


Still, lithium batteries have their own characteristics. Here are some of them:

  • They are sensitive to low temperatures, so try to use the device less in cold weather..
  • Lithium batteries “do not like” a full discharge, so try not to let your device run out of battery.
  • It is believed that the optimal state of a lithium battery is about 50% of the charge, that is, charging it to 100% is also supposedly undesirable – 80-90% is enough. It’s hard to say whether it is it or not..

From experience with use, we can say the following – the discharge depends not only on the battery capacity, but also on the optimization of the device’s system. If the optimization is poor, even with a very powerful battery, the discharge will occur very quickly. Of course, all other things being equal, including the processor model, screen size, resolution, etc. And dancing with tambourines in the form of “pumping” the battery will not help.
