If you claim that your product does an ‘x’ thing and then finds that it doesn’t, it’s okay for people to get annoyed.

Regarding fast charging: –

Quick charging will not damage your battery

“A conventional charger has an output of 5 to 10 watts. A fast charger can improve it up to eight times. For example, the iPhone 11 Pro and Pro Max come with an 18-watt fast charger, while the Galaxy Note 10 and Note 10 Plus have a 25-watt box. There is a charger. Samsung will sell you an extra-speed 45-watt charger for 50.

If you do not have some technical faults in your battery or charger electronics, however, using a fast charger will not cause any long-term damage to your phone’s battery.

The reason is here. The fast charging battery works in two stages. The first step is to apply a voltage explosion to an empty or almost empty battery. It gives you 50% to 70% burning charge in the first 10, 15 or 30 minutes. Because in the early stages of charging, batteries can absorb charge quickly without major negative impact on their long-term health.

For example, Samsung promises that its 45-watt charger can go from zero to 70% charged in half an hour. Apple says that the fast charger that comes with its iPhone 11 Pro can charge 50% in 30 minutes.

Do you know how long it takes to charge the first 70% or 80% to fill the last 20% or 30% of the battery? That last part is the second charging stage, where the phone-makers have to handle the charging speed slowly and carefully otherwise the charging process can actually damage the battery.

Arthur Shea, a tear-down engineer at iFixit, a DIY repair site, suggested imagining a battery as a sponge. When you first pour water over a dry sponge, it absorbs the liquid quickly. For a battery, this is the fast-charging phase.

As you continue to pour water over the wet sponge growing at the same rate the liquid will turn into a bead on the surface as it fights getting wet on the saturated sponge. For a battery, this unabsorbed charge can result in shorts and other problems that could potentially damage the battery.

Damage is rare when everything inside is well managed. A battery management system closely monitors the two charge stages and reduces the charging speed in the second stage to allow the battery to absorb the charge and avoid problems, which can take up to 10 minutes to get to the last few percentage points.

The Samsung Galaxy Note 7’s tragic battery explosion was caused by a flaw in the battery design rather than the phone software’s battery management techniques. “


Also, from Articles: –

“Based on our experiments using Google’s official 30W USB-C adapter and a handful of compatible fast charging cables, we’ve discovered that the maximum power from both the Pixel 6 and Pixel 6 Pro is only 22W, on average only 13W. During testing we didn’t see speeds anywhere near 30W charging that many (quite fairly) have assumed the Pixel 6 series is capable of.

We have supported these results through experiments using other high-power USB power delivery PPS plugs such as the Anker Nano II, Samsung 45W Travel Adapter, and Elecjet X21 Pro – all of which have shown a maximum 22W output when charging the Pixel 6 or Pixel 6 Pro. All of the adapters used were UK variants, although our data from testing US chargers with USB PD PPS support shows a maximum charging of 22W or below on the US model Pixel 6. “
