Xiaomi's 200W charging degrades 20% of battery capacity in 800 cycles

11 June 2021
Depending on your usage that could be several years of charging, however.

20% after 800 FULL cycles??? that's amazingly good!! I know people with Iphone 11, used for a bit more than a year and the battery was DEAD, basically last for few hours.

You seem to think a company can't simply pay for these certificates. And what certificates are you referring to? Until others provide similar results in real-life scenarios, any test is taken with a grain of salt.

"Clearly you are some teenager who still believes in the bad stereotypes about Chinese phones"

Yes, it is very "clear" that I'm just some teenager who believes in stereotypes. You can see me through the monitor, that's cool. I mentioned before that any company who makes claims shouldn't be trusted so easily, not just Chinese.

Also, when did anyone mention Sony? Even if Sony made claims like this (which they didn't), I would still be skeptical of it, controlled environments don't necessarily represent real-life scenarios.

It looks pretty simple for me than if you log the current entry, by the time and compare to the % of battery charged, you can easily see how is the capacity, that's basic maths, the only thing that can be wrong are the sensor accuracy. Also using multiple charge log alows to refine the calcul.

Android-Authority, 14 Jun 2021Most of these guys are stuck on sub 25W charging. It'... moreThat definitely is the case here.
The degradation seems quite a lot here tho, it will definitely be improved by the time it reaches phones.
And replacing the battery after 3 years is definitely cheaper and time saving than having to wait hours for your phone to charge imo, in case one decides to use the phones more than that. Neither are Xiaomi phones difficult to repair.

What they don't mention is the battery degradation with charging cycles in general, no matter the charging speeds plus battery degradation overtime with daily usage and change in battery temperatures from one extreme to the other.
Battery degradation due to chargers was very less to begin with but now it is 20% + adding all the other factors this charging tech will degrade batteries faster than usual, that's for sure.

Regardless I do see where you're coming from and you do make a fair point.

When it comes to the tests, I don't believe anything posted by companies regardless if they're Chinese or not. Battery tests such as this I definitely take with a grain of salt. I just don't understand how some think this as something reliable. Companies have been dishonest about many things before like Samsung and Huawei with camera samples and Apple with their throttling.

SuuperBaka, 11 Jun 2021Whether he's being hateful or not, he's not wrong... moreCompanies that conduct businesses outside China could face the consequence inside the countries they operate in just in case they were found out to be misleading customers with their ads. Moreover, China also has their own law which prohibits companies from relying on false advertisements - so whether they were Chinese companies or not, they would be screwed either way if they were caught red handed.

When companies introduce new features, they almost always have tested them in a specific controlled environment which sometimes may not reflect their real world performances, and so yes people should always take official test results with a grain of salt. But the problem with his comment was that he was mixing his usual xenophobic attitude into it which was clearly unnecessary especially given the context.

Who wrote this article,

A. Its number self published by manufacturer. Take it with a grain of salt.
B. Lest simplify the number, 20% per 800 cycle is 9.1% per year(one charge a day). Nearly 10% lost per year and that somehow its something that they proud of. Makes me wonder how realme battery degradation number.
C. To compare, old Qnovo charging is aiming for less than 5% per year battery degradation. Outside smartphone, car and driver's Tesla lost 5.1% per year.
