How to charge your phone properly [e mais rápido] | Cell phone

Problems with the cell phone battery are more common than we would like. But did you know that the way you use your smartphone and charger can influence the component’s life? To avoid routine errors that can harm the device, here are some tips on how to charge your phone correctly and learn what not to do during the process.

Lithium-ion batteries, when they get close to the void, begin to draw a constant current and operate at low voltage, which is beneficial for the component’s health, according to Battery University.

The tension starts to increase as more load is acquired, therefore, it is recommended to keep it in a range below 100% – between 80% and 30%, to be more specific – so that the process requires less stress, prolonging the battery life.

What NOT to do when charging your phone

1. Always charge up to 100%

We know that seeing the battery icon completely full can give a feeling of peace in the heart of those who have a hectic routine. But this practice, on a recurring basis, is not so good for lithium-ion batteries.

You may have noticed that newer phones with fast charging systems often boost at the beginning of the process, and then slow it down. There is an explanation for this.

According to Apple, the slowest recharge from 80% is a matter of longevity. On iPhones, charging can be paused at 80% when the battery temperature exceeds the recommended limit.

Therefore, the habit of charging at night – that is, charging the device all night, and unplugging your phone only when you wake up in the morning – is not at all healthy.

2. Allow the battery to zero before charging the phone

In the same way that reaching the maximum is not indicated, the opposite extreme must also be avoided. The ideal is to keep your cell phone battery in the range between 20% and 80% to increase its useful life.

You don’t have to be afraid to make small battery recharges, adding about 10% over the course of the day – this practice is advisable. But if it is impractical for you, at least try to monitor when the device reaches 50% charge to complete it.

If you are planning to spend a lot of time without using your phone, keep at least half of the device’s battery capacity charged – the tip is Samsung.

3. Expose the phone to excessive heat

Avoiding exposure to heat can be one of the most difficult recommendations to follow depending on your profession and the region where you live.

I’ve had enough of seeing application drivers suffering from this problem in the heat of Rio de Janeiro, with the phone stuck to the car’s dashboard in a sun of over 40 ° C, and still connected to the charger. Still, the tip is valid for anyone who can follow it.

And use heating also counts, see? No spending hours playing with the cell phone stuck in the socket, already with 100% battery. Use the device normally and, when you need to, recharge – you’ll save your pocket in the future.

How to charge your phone faster

To charge your smartphone quickly, try to avoid the resources that force its use during the process, even in the background.

A simple tip is to turn off your cell phone – but if that is not possible, avoid using mobile data or searching for a cellular network (especially where the signal is not there) by activating airplane mode.

Finally, it is worth remembering that eventually the battery will die. You probably won’t notice this if you follow all the tips correctly and change your cell phone within two years. But wear and tear occurs naturally, no matter how careful you are. Aware of this, don’t worry too much about the subject and just try to preserve good habits. 😉
