Since 2017, Apple has supported fast charging on iPhone 8/8 Plus and iPhone X models, followed by iPhone XS/XS Max iPhone XR, iPhone 11, iPhone 11 Pro/11 Pro Max, iPhone 12 mini, iPhone 12, iPhone 12 Pro/12 Pro Max.
Although it has supported fast charging since 2017, until 2019, Apple only supports giving an 18W fast charger (previous iPhone models are always included with a 5W charger) on the two iPhone 11 Pro / Pro Max product lines and this is also the case. is the only model that comes with a fast charger. Through 2020, when launching 4 iPhone 12 models, Apple has cut off the gift of a charger.
The shortening of battery charging time is a trend of technology firms in general and Apple in particular. However, because Apple is “behind” many Android companies and the batteries of the iPhone lines are not as “buffalo” as they are, making many iFan worried about fast charging that will cause the iPhone battery to be bottle.
Let’s learn a bit about fast charging technology and how it works, the battery when fast charging will be fully charged in 2 stages:
– Stage 1: the voltage will increase when the battery is about to run out or run out of capacity. In the first 10 – 30 minutes, users can charge 50 – 70% of the smartphone’s battery.
– Stage 2: battery charging time from 70% to 100% is also slower than the first stage because the voltage will drop.
Do you know how long it will take to fully charge the last 20% or 30% of the battery like the first 70% or 80% charge time? Those last battery percentages are the 2nd charging stage, the manufacturer has slowed down and carefully managed the charging speed, so that it doesn’t affect battery life.
“Imagine a battery like a sponge. When you first pour water on a dry sponge, it absorbs the substance,” says Arthur Shi, an engineer at DIY repair site iFixit. liquid quickly (for batteries, this is the fast charging phase) and as you continue to pour water over the sponge at the same rate, the liquid will overflow (for batteries this unabsorbed charge may result in a short and damage the battery)”.
According to the 2-stage charging principle, fast charging technology does not affect the quality of the iPhone battery or the battery quality of any smartphone, users can completely freely use fast charging, without worrying about the bottle. battery or damaged.
