Great video, but still doesn't show the whole picture. There are more factors to the degradation of a battery than only cycle count. Heat plays quite an important role (and that's a problem with wireless charging, also, in day to day use nobody discharges battery down to zero, then charging too 100% and repeat. Lot of phones charge up to 85%, and by the end of the day there is usually still around 20% or more. And because most of degradation happens at an ends of a voltage range, this drastically extends battery lifetime.

I don't know I have an ASUS ZenFone 6 from july 2019 that I still use it has 1200 charge cycles on it it says almost 5500ah on the original OEM battery a little under 5ah battery it charges at 15w so almost 1c every time it says 83 percent capacity remaining I think that's pretty good
As for the faster charging my current phone charges at 60 watts after 2000ah and 770 charge cycles it still says 98 percent. This phone is a 2 cells in series battery 2. 65ah each i got it in January 2022

GreatCreatorlab!
Recently my phone charger stopped working and I quickly opened it up and measure the resistance of a discharge resistor and didn't find anything afterwards I removed the resistor and measure it again I found that it's 220 ohm I simple put it again and then my charger got a fast charging feature so I didn't notice what happened and I find you saying that it damages battery life when you fastcharge it

Hi! Really nice content as always!
I would just like to point out that the ageing behaviour of lithium batteries is linear only after a first period of chemical balancing inside the cells (which induces a streep drop in capacity. This means that in the first hundred of cycles, the capacity could degrade by even 5%, but then it would stabilize to a much lower (constant) degradation per cycle value.

I thought it's been well understood now that the harder you charge/discharge a battery, the more heat and thus more damage you do over time. I already choose to charge my phone wirelessly for the reduced load on the circuits/battery for that exact reason. It's more well understood in industrial/commercial settings where a battery may cost a years worth of pay or so in my experience at least.

The convenience of fast charging outweigh the capacity drops over year tbh, my phone fully charged in 30 mins, when i wake up in the morning and realized i forgot to charge my phone last night, i just need to plug it in, do my hygiene, change my clothes and have breakfast, by the time i leave my house it would be fully charge, ready to be used for the rest of the day

I have a Redmi Note 10 Pro with 5000 MAH battery and I got a 33w charger in the box, phone battery lasts at worst 2 days at best 4 days and it only takes me an hour to charge and immediately after charging I unplug it, that means I charge my phone around 180 times a year, which means battery would take more than this much to lose 12% of its capacity.

Hey, great video like always. From a past video where you made your own esc, i got an idea to convert my go kart to electric using a car alternator converted to an electric motor and i was looking at available high power esc and they are really expensive, and i was wondering if i can make one, maybe you could make a video about making one?

After a little over 2 years with my oneplus 9 and its 65w charger, I have lost 16 percent according to the accubattery application. I can live with this loss, the comfort of knowing that my battery will be recharged within just a little while (30 minutes 0-100%) is too good to give up.

A phones fast charge doesn't actually constantly charge at 5A. The higher the battery percentage is the slower it charges to save the battery.
Slow charging ultimately is still probably better for the battery, but definitely not as bad as this video makes it out to be

Hearing that 3. 55V is considered 0% makes me feel a lot better about all the times I let my phone discharge to stone dead flat - even with the slightly higher chemistry that shouldn't be too bad for the battery, and explains why my battery isn't completely dead lol

This was a great project, but I still think fast charging my phone is a good idea, yes I lose some capacity but no problem in 4 years I just buy an original iphone battery off their website and fit it in, all the time saved for 80 in 4 years? Think its worth it

Would be interesting to do the same test but with different levels of discharged state, I personally never let the battery go below around 50% and have yet to find a difference in my phones ability to retain charge, even if the fast charge's rated for 6A 120w

Scott, your previous videos were not really interesting for me, but when I saw the title I was really hyped! But I was extremely disappointed when video ended with you testing only 100 cycles. An absolute failure. Please test it with more cycles

I'm not an expert here, but how would a two-battery system like my oneplus has be affected? Since fast charging is 6. 5A and charging is done in parallel, would that mean 3. 25A per battery and therefore less impact on the lifespan?

This is why I keep a old charger (that can make 800mA IIRC) on my nightstand and put the fast charger on my backpack. When I'm on the go and need to put some charge faster, it is with me. At night it can charge as slow as it goes

So after watching the video my conclusion is still to use dast charge, since after 2 years no matter how you charge or use rhe phone the battery capacity is getting bad and the battery needs replacing

You should continue this experiment maybe a about 300 or 600 or why not 1000 charge cycles, because most people keep their phones around 2-3 years. Then we could see the drop in real life

If you want to absolutely optimize battery health, I'd skip wireless charging since it just generates extra heat. Although then again 720ma is so damn low that might not be a concern.

8 layer PCB! Very cool! I remember using a dual layer copper plated boards that were mechanically etched with a lathe bit for my circuit boards! Kicking it very old school there.
