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.

Sort by:

[deleted post]Yes, I will think the same.
For me, it is okay, battery loose 80% capacity after 2 year of use. At that time, I might be change the phone with new one.

When you charge from 10 to 100 it's not 1 cycle. Until you charge more 10% in another charge

well, if only battery can be replaced as easy as that, they can further increase fast charging, 800 cycles of charging discharging might be enough for most people...

Agree to disagree, it's time for better battery tech. Graphene needs to be further researched.

Most people keep their phone for 2 years, that's about right

They are increasing "bandwidth" to allow for better speeds

"And here's another fact of life - no matter how slowly you charge your battery, it will have deteriorated after 800 cycles. Heat is the number one culprit of battery deterioration so whether you keep your phone tethered to a 5W charger for 5 hours or 200W charger for 10 minutes, it's the amount of heat that your battery deals with that will diminish its charge the fastest. And all batteries lose capacity after years of use, so given the insane speeds the numbers cited by Xiaomi actually sound very reasonable"

NeverOpnReplies, 11 Jun 2021Yes kinda agree with this article. I'm experiencing c... moreBut the high temperature is only limited for the a few minutes unlike other phones which are plugged to the charger for hours.

Never seen my wife's phone go beyond 49°C peak temperature here in France.
In the winters, it never went beyond 40°C during charging the phone.
Five minutes of charge is filling up 35-40% battery.
One can easily limit the temperature to 45° or lower in settings, here the peak charging speeds will be lower and it may take 10 more minutes than usual for full charge.

i hope more phones use that dual-cell technology

iPhone + 5000mah + 65w charger = superb battery life and 30 minutes changing time

It's a no brainer for me if I can get my phone to charge 5x quicker the first two years it's a gre6 deal If the battery starts to go bad after two years doesn't really matter I will already have a new phone.
I spend more time.on my phone then on my car I'm.not dirt poor I can afford upgrading phone every 1-2 y
I still spend 100x more on my car then my phone but use it less.

Shadocx, 11 Jun 2021Ok, boomer.One of the reson is that they are playing catch up whit the already established brands they are
Spend their money on a&r Insted of marketing like Samsung
Why would I not want a phone that charge as quickly as possible my mi ultra is 7 months old I don't see a difference in battery capacity and it charges so much quicker then and other phone I have ever owned going back to Samsung would be a big step back.

I’ve an iPhone 11 Pro, 3049mah battery still has 95% of original health and it’s easily beating the previous Huawei Mate 20 Pro I did have on day-long longevity in terms of battery usage.

Charging your phone reasonably is under reasonable phone usage, if your gaming a lot for instance and need a mid day charge, expect that your battery will need replaced far sooner, dash charging a few percent does a battery no good.

20-30w region is fine, at this point its simply a market technique..

[deleted post]That's true.... Sony & Apple last only 300-400 cycles before they start degradation, when paired with 18W-20W charging.

Xiaomi designed batteries last upto 600-800 cycles before starting degradation, when paired with 33W-55W charging.
