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

  • Fantastic video, I used to obsess about keeping my phone between 80% and 20% - it's crazy how the landscape has changed and how fast we're able to charge these things.

  • Really well researched and informative video. Thank you!

  • Always did appreciate time and dedication your put into these tech videos. You’ve always been a very reliable source for all things tech related

  • Hey Marques! I worked in the battery industry for 7 1/2 years. I can tell you that if you are very worried about battery health, long term, use the slowest charger you can and don’t use your phone while charging. Charging solutions are improving but lithium batteries have not changed much. I use the 5 watt charger still on a timed plug overnight. My iPhone 13 Pro’s battery health is at 99% still, I have had it since launch. I actually tested this theory with my iPhone 12, I used the 20 watt charger instead and sometimes wireless charging, both of which cause more heat. I saw much more battery degradation in the same time period. I am super interested in what some of these companies have done the last several years and ultimately I think some developing technologies that are on the horizon will solve this issue entirely.

  • I really just want a smart phone with a replaceable battery. Like a panel on the back I can pop off and pull the batter out rather than having to fully disassemble the phone.

  • Nice break downs. You explain tech quite well. Glad I found your channel.

  • Okay, I understand the point of reducing the charging time from to 2 hours to like 20 minutes. But is it really reasonable to minimize it even farther? Seems like there is not much difference for the average user whether it charges in 7 or 15 minutes. It could be useful for big batteries, like in electric vehicles, where charging time is still a big factor, but in phones it looks like it becomes just a marketing tool, just like megapixels in phone cameras back in the day.

  • I really appreciate this in- depth review regarding charging 😊 I generally use super fast charging on my S22 Ultra for short periods at home or when I need a quick charge before heading to an event. Regular fast charging is fine for me when I'm just at home. When I've been using my phone a lot watching or making videos, etc and it starts to run hot, I just shut the phone down and let it recuperate before I use it again.

  • The research that you dug in is just impressive. I feel like this content length isn't lengthy but feels like just 3mins of content. I really enjoyed and learnt a lot from this content.✊

  • 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%.

  • I would say for modern devices like smartphones, laptops, cameras, etc, you're OK to fast charge them. However, I still think there may be a valid concern for things like rechargable batteries (like rechargable AA/AAA batteries, etc) as the batteries themselves maybe have less components to control the rate of charge and I think those will suffer more over time from consistent fast charging, but devices with built-in Li-Ion batteries I don't think it matters as much. But as with all batteries, they do start to lose their ability to hold a charge after a while and have a finite number of charge cycles (regardless of how its charged) before the battery simply won't hold a charge.

  • Overall I think this was a great video! One critique though:

  • Love your channel. I mostly watch it when I'm about to buy some new tech, then I wind up going down a rabbit hole of related videos, just cause I like watching them... Btw, just traded in my 2-yr old 12 Pro Max which said its battery was at 88%. However, shortly before trading it in, I began getting a lot more overheating warnings, which I never used to get. This was usually when on its wireless charger (Quadlock) on my dash (which I know isn't a good place). I need to relocate out of the sun. Question/myth you might want to do an episode on: Do phone cases allow phones to get hotter, but acting as an insulator, rather than a bare phone being able to dissipate its heat?

  • Another solution is, use "slow" chargers and keep the battery charge levels between 20 and 80%. Only use (super) fast charging when you really need it. I use my fast charger for travelling only, which is when I normally need fast charging and the rest of the time, just use the 20-80 rule :)

  • Love watching your videos man. You do a really professional job explaining things.

  • 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,

  • Your channel is quickly becoming one of my most trusted and on-point resources. Masterclass in presentation too.
