Not the first time that we mentioned that batteries are a component that does not seem to be progressing at the same level as other smartphones. And although we've jumped to 108 megapixels, under-screen fingerprint readers, and the cameras under the screen have quickly changed, battery technology hasn't changed much in the past decade.
This does not mean that there have been no improvements, but they are almost done in charging and not in the same battery. On the other hand, graphene batteries do not look like they will be used soon either, so everything indicates that lithium ion batteries will remain standard for years to come.
This technology of the fast charging technology sparked controversy because it has been proven to cause battery life to erode faster. But is this really important? It's important, but this is not something that I think you should worry about.
As I mentioned, researchers at Purdue University found that fast charging consumes batteries faster because it includes more powerful poles in the batteries with a higher charge rate. Due to this damage caused by the accelerating electrons, however, the damage is not so high that it is a problem in the average useful life of the devices.
Usually the battery life of smartphones is 1000 complete cycles, i.e. a complete charging process from 0 to 100. This means that if we complete a charging cycle every day, the battery should last more than 3 years without problems.
This does not mean that during those more than 3 years, the battery will take the same time to charge or will continue as it is, because the wear and tear will make these two processes also decrease over time.
If we add to this what the search for wear and tear says the battery on fast charging equipment, this does not mean that the battery will continue in fewer cycles, but rather that the corrosion will be more evident in less time, and the battery will last less than half of what you do now, because the corrosion is advanced and should Not too surprising.
Another detail that we should keep in mind is that most users usually change their phones on average for two years, so maybe the damage caused by fast charging is something that greatly affects the experience of use and pushes them to change the phone.
In my case, I still have the Galaxy S8 I have been using for 3 years, it has 15W fast charging technology and the battery still has some time. It is true that it is not like the year or the year before last, but I can say that the phone is still usable when it comes to the battery.
It is now common to see phones with larger batteries, so damage within a few years is more likely to be less visible or less annoying.
