This was perfect for me, i just got a powerbank and since the VisionPro release I have learned that comparing MH isn't the best way. My powerbank has 38.5 Wh so now I know for sure how big it really is, thanks ❤
6:52 I think they should show the laptops battery also in mah because even tho they are same watt hours the gaming one will give less battery life compared to the other so the people can get a idea of what to get I was also confused why they all have similar watt hours but the non gaming ones can give good battery life.
I used to own an Anker 15000 mAh powerbank and had a phone of 3700 mAh capacity. It would always confuse me why the equation doesn't add up simply and why I don't get to charge my phone 4 times with it fully. After watching this video I understand it and feel that most powerbanks are actually falsely advertised because they would show a high mAh number but a lower Wh number. Making you think that great it's going to give me multiple charges but it doesn't go that way. For all this time I just blamed the power loss due to inefficiencies during the power transfer
Thanks for this video. I did't know that Wh takes into account voltage. I assumed mAh and Wh were just different sizes and that mAh was used for smartphone and wAh for computers. As I am looking for a power bank now I know what to look for. Greeting from Bulgaria!
Does a 10,000 mah lipo battery last 3-4 times longer than 2,200 mah lipo battery?? Same brand, same volt, etc. Is the mah increase in size equate to longer use with an RC plane or car???? Thanks in advance for your help here.
At 08:20 i cant understand why According to me, we should actually look at how much charge the console needs from the powerbank, it needs 2590 mA and the powerbank can give 25,000 mA. So why cant it simply be ~10 times. How and why does W come into picture, if the same amount of charge needs to be transferred? I am real confused
Because the voltage is different. Since the ROG Ally takes in 15.48V, the power bank needs to do a lot of power conversion before sending it to the device. The wattage is looking at the amount of pure energy, after the conversion, no matter what is the voltage or current.
I would like to ask if you could test the ROG Charger hub with PPS and battery bypass, plus cooler on games via HDMI on Dex. That's basically using a phone as a gaming console with no battery and looking for throttling, vs. temperatures. Yuzu and Genshin Impact could be good candidates if you will. Snapdragon 8 gen 2 and 3 as well. No one has done that yet and that seems great. Thanks.
8:40 Fun Fact: Apple only writes the rated capacity on their batteries and that's why their capacity values are always looking so "odd" For the better though, as all batteries have or exceed that value, unlike with Typical battery capacities and as we should be using Wh to begin with
@@NasiLemakTech but any idea about grainy display ? That it can be fixed via SW or not ??? Or it is a hardware issue ? Can u pls confirm only this... That it is a HW issue or SW 😔
Imo all the battery comparisons in the end do not make sense. As the user behaviour changes according to the battery life we are getting on per day basis. We will automatically adjust to the battery life we are getting wether it is a cheaper or an expensive phone.
i get your point, but unfortunately it's just really wrong from the start up. mAh (C/1000/s*3600*s) is actually the dimension of charge, which correct for capacity. what you are trying to say is that the capacity of a battery doesn't matter for most things, because what we are interested in is the energy conent, which you can give in Wh (J/s*3600*s) because that has the dimension of energy. that is a legit point. but what you are saying in the first minutes is just wrong and makes things extra confusing.
i think that my issue is that "battery capacity" is an actual technical term. you should argue that it's irrelevant for most people, not that for some reason mAh is a wrong unit for capacity, because it factually isn't.
mAh is not the capacity. It doesn't actually mean anything as we only use mAh as the "battery capacity" if we assume the voltage is the same across all batteries. As single-cell batteries like 18650 or 21700 batteries then sure - that's completely valid. But for devices like phones and tablets and power banks, we can't do that. We need to account for the voltage for the true amount of energy in that particular battery. Wh - or in other words, Joule - is the true battery capacity.
@@NasiLemakTech im sorry but this is wrong. the capacity of a battery is measured in mAh, because it must have the dimension of charge. capacity just isnt a measure of how long your phone will last. because that depends on the energy content, measured in Wh, the dimension of energy. you can just put it in google and one of the first things that pop up is a sciencedirect article by elsevier. and they explain it in the abstract of that paper. trust them if you dont trust me. even if theyre not the layman's understanding of a term
Correction! At 2:50 we should divide 1000 to eliminate the mili, not multiply.

Correct bro 👍🇮🇳👍
I use joules 🗿
The only correct unit 💯
I use Electronvolt 🤓🥸😎
Coulombs 🗿
No. of Electrons 🗿
This was such an informative video❤
Hope more people would understand this concept
Great vid. Keep doing something like this. I enjoy em.
Glad you like them!

Great vid. Only one thing... at 2:52, shouldn't it be divided by 1000?
Aw shit yes, should be dividing by 1000

So now you know! That is exactly why Wh is a proper measurement for battery capacity, not the mAh value

Thanks for the info man! This will be super helpful for when I have to start designing my own electronics. New sub!

If it's the same voltage then the 10,000mAh will last longer - because the Wh value is also higher.
@@NasiLemakTech Thanks!
Very useful information ❤
Great video I had been wondering about the APV battery and why it was so huge given the Mah. Thank you!
You're welcome!
Thanks for the information i loved it. I understand things better.
Very informative video thank you sir from India 🇮🇳

The wattage is looking at the amount of pure energy, after the conversion, no matter what is the voltage or current.
Most power bank don’t advertise the voltage
Do we just estimate voltage to be 3.7? The nominal voltage of a lithium cell
Power banks usually have the Wh value listed though.
Never assume the voltage, however.
@@NasiLemakTech thanks!

Oh I didn’t realise that. Thanks for pointing it out!
I have a UNEED Quickbox C30 which is rated 30000mah that can output 65W. How do i know the Wh of my powerbank?
That information is not always available. Probably has exceeded 100Wh limit for flights
@@NasiLemakTech Appreciate the reply!
Good day! Do we know the Wh for the S24 Ultra?
I saw on a s24u battery replacement vid... that the oem battery is rated for (Typical Capacity: 5000, 19.40 wh, 4.47V)
Should be the same as the S23 Ultra.
The 4.47V is the charging voltage btw.
Formula is (mAh)*(V)/1000 = (Wh)
So it is 22.5 Wh :).@@truepotato3050
Great info, some pointless info on ur video production thrown in but still good 😄
Please do something about S24 ULTRA Display. . i watched your video abt display, but next video when ??? About the display problems nd solutions
Waiting for the update. Can’t do anything until the update arrives
@@NasiLemakTech but any idea about grainy display ? That it can be fixed via SW or not ??? Or it is a hardware issue ? Can u pls confirm only this... That it is a HW issue or SW 😔

Amazing 👍

Yeah your battery life usage is not going to be the same as mine because of how differently we use our phones.
Everything is anecdotal.
Yes, which is unarguably the biggest reason why SoT is such a bad metric 😅
Great video

the thing that you are halving is the capacity, not the current.

the twitter community note is equally unhelpful. "true capacity" just aren't reasonable terms to use. all it does is confuse people even more.

im sorry but this is wrong.
the capacity of a battery is measured in mAh, because it must have the dimension of charge.
capacity just isnt a measure of how long your phone will last. because that depends on the energy content, measured in Wh, the dimension of energy.
you can just put it in google and one of the first things that pop up is a sciencedirect article by elsevier. and they explain it in the abstract of that paper.
trust them if you dont trust me. even if theyre not the layman's understanding of a term
This is really eye popping🥲

Next topic Sodium-ion vs. Lithium-ion Battery. 😊
I'd love to tackle this and also graphene batteries too. Kind of out of my expertise
Nice!
Phone bigger battery sir deswai it can last so long
Bigger than my duck 🦆
