Does repeat fast charge damage batteries?

[EZhere]

I saw this issue addressing iPhones elsewhere but I’d appreciate some clarification, and if it applies to Apple or x-devices across the board. I’m using high rate fast chargers daily on several devices (iPad Pro 5, iPad Air 5) and iphone 7. Usually, it’s 2 iPads since I’m on each for about 3 hours. Sometimes I do the same with MBA M1. These are ~1 year old, they deplete to ~50% quickly, so I swap and cap off to 100%, and this goes real fast. FWIW, an other iPad Pro 3 just went kaput but it was older. I’m curious if this routine is damaging to these batteries, e.g. using up some allotted recharge cycles, or other? Thanks.

Indeed, but there are many factors that contribute to the degradation of a battery. In my personal experience with various gadgets these years, using fast, standard, or trickle charging methods did not make a significant difference.

No.

From a reliable source online;

Fast charging is not inherently bad for your phone. The risk comes from the heat that a fast charge generates.

Okay, thank you for the replies…which raise a sequitur: I wonder why Apple and others don’t simply 2x the charger capabilities to please the users or gain a competitive advantage? I can’t image it’s a cost thing, which it would be if we were referring to electric automobile batteries.🤷‍♂️

Average Apple users buy Apple products despite the mediocre charger capabilities, not because of it.

I would say, why invest in fancy charging specifications like 20V5A when it's not the top priority for the 68% or even 95% people?

Because numbers wise, that is a significant amount of potential buyers.
Then there are other uses.

That’s a good answer and is likely the precise reason!

Since you have a Mac, get CoconutBattery and monitor the battery temps via different charging wattages. I feel if they were really concerned about battery longevity, which I feel they are there are more technical challenges that you'd initially think of. Also there might be some politics involved. Apple prefers their own standards, and what obligations due they own their MFi affiliates if this requires them dropping a current standard.

They might be thinking that something totally new outside of standard fast charging options we've seen for years is a better approach. 🤷‍♂️

My wife bought an Amazon basics dual port 36 watt charger by mistake. I tried it out on my max and it gave a nice charge in about .5 hour. That’s not mediocre, may not be the fastest.

As an aside, your discovery may be a good opportunity to try some of Amazon’s device batteries. ‘Like many here, I presume, I have too many gadgets…and use a lot of alkaline and lithium Aa, aaa et al batteries.
