Everything You Need to Know About Charging Smartphones
Does it matter which charger is used to inject life into a discharged battery?
Does the type of cable matter? And which company has developed the fastest technology in the world? all the answers.
There will always be situations where your smartphone will come to life in the middle of the day and you will find yourself looking for a wall charger.
If you have time, the answer is no: you can simply connect almost any normal charger to your phone; Especially today, when most cables and smartphones already come with standard USB-C connections. Modern devices know how to regulate the incoming electric current themselves to protect the battery, so there is no danger of the phone exploding due to too strong a charger.
Apple, for example, is no longer charging for its new iPhone 12 models; It builds on the huge volume of cargo on the market – for her, you will find one, no matter which community.
But in most cases, the time factor has great significance: you need a functioning device as quickly as possible. And here there are definitely differences – even big ones – between the different cargoes, especially in an era where high-speed cargoes are common, and the variety in the market is growing. And we have not yet talked about the cables.
50% in 5 minutes.
When you think about the claim, imagine a pipe through which electricity flows. The pressure in the pipe is the voltage, which is measured in volts, and there is also a current – the pipe capacity in this analogy – which is measured in amperes. When you multiply these by each other you get the power, which is measured in watts. Power is the “power” of charging. Thus, laptop and tablet batteries will require higher wattages.
Not every phone knows how to get all the power. If a phone that supports only 5 watts is connected to a 20 watt charger, it will receive only 5 from it. How do you know how many watts your phone supports? Because of the pace of innovation in the field, the only way to know this is to check the device specifications. If in the past all USB devices were charged with 5 volts and only with a different current, today the devices can also be charged with a different voltage (voltage) if they detect a suitable charger.
The charger that came with the phone is the most suitable
On Android devices, the most popular device for fast charging is Qualcomm’s Quick Charge, in its various versions. The latest standard, 5.0, was announced this year on July 27 and supports – theoretically for now – up to 100 watts. Meaning: A cell phone with a 4,500 mAh battery, which will be charged with a compatible charger, will reach 50% charge in just 5 minutes.
In any case, for fast charging you need a charger that provides the maximum watts that your phone can receive in the standard it supports; There is no point in looking for more than that. For the most part, the charger that came with the phone is the most suitable. Maximum charging speed is related to the level of the device: for example, Samsung’s cheap Galaxy A11 offers 15 watts, but you can charge the Galaxy S20 at 25 watts, and the luxurious S20 Ultra at 45 watts.
Check the packaging
Although the fastest charging company is American Qualcomm, the fastest technology was introduced by the Chinese company OPPO in July this year: Flash Charge is capable of charging 125 watts at 4,000 mAh in just 20 minutes. The closest competitor is VIVO’s Super Flash Charge – both Chinese and part of the giant BBK corporation – with a power of 120 watts. Despite the impressive announcement, it is unclear when and on which cell phones and chargers the new technologies will be integrated.
