Does Fast Charging ACTUALLY Ruin Your Battery?

60 watts? 120 watts? 240 watts? Here's what REALLY ruins batteries, explained.

You're becoming more of a truth seeker and journalist than before, you're adding a lot of value as you evolve beyond just reviewing tech to actually help us understand how it works. Thank you Marques.

As a retired engineer who specialized in battery technology, I'm here to say you've done a perfect job explaining battery charging.

I love that your videos dont have background music ... & you speak to the audience at a natural pace. Also appreciate your effort to learn the stuff before conveying it to us, thanks bro! :D P.S. Love the humility in your speech, never change!

Change audio soundtrack to French, go to 6:53 --> welcome to the future of youtube.

I just want removable batteries to make its comeback.

Ok, fast charging allow you to charge FAST between 20% to 80% (in 10 minutes with a 120W fast charger). This interval is perfect to preserve battery life and doesn't create much heat. I have a 120W fast charging phone and after one and a half year, I lost ~4% of battery capacity (I use Accubattery to estimate the battery degradation). Basically my battery life hasn't really decreased and I don't have to wait for an hour to use my phone again.

don't activate french audio on this video, it's a nightmare ...

u have no idea how much we trust you and how much those videos help us, thank you

Man I miss the days of user swappable batteries. You never had to worry about running out of juice. You just carried extra batteries with you and in just a few seconds you were back to 100%.

Many years ago I was a programmer writing software for a battery development lab. One of the biggest things that we were working on was the most effective way to charge particular types of batteries. We had engineers, chemists, physicists, and, of course, programmers involved. An astounding amount of science for a simple process.

Very well documented, the depth of knowledge in 12mins. Hats off

[danj]

Awesome video bro. Brilliantly researched and presented. I work with all different types of batteries for work and I agree with everything you said. 👍🏼

Linus did some experimenting on this a while back, IIRC he found that it's less about how fast the battery is charged, and more about the range. Fully charging and discharging battery puts a lot of stress on it. Doing so repeatedly degrades the battery. Doing so repeatedly while also at high temperature, _really_ degrades the battery.

An actual test of this would be fun. Charge a few different phones at different wattages over 100 cycles, measure heat during charge, and measure capacity at the end.

[frankdrake]

Awesome video. I appreciate the research you did for this. Thanks ! 👍

[jakesilver]

This is something I always wondered about, thanks for a very informative video

[guruoo]

I'd certainly take a thicker phone if it meant improved durability, sd card slot, and room for a larger, and/or user swapable battery.

[NsteveA]

This has got to be my all time favorite MKBHD video! It's literally everything you need to know about your phone battery.

Thank you so much, Marques, you're a wonderful teacher. I'm really glad to have found your channel. You're a smart guy and a great communicator.

[Elvanion]

Very solid jnfo and exactly what I was looking for. Your style of presentation is easy to listen to. Thank you.
