[@rwestvang]

It's not the 45W charger that's the problem, it's the phone itself. It's the phone that determines how much mAmps it's drawing. You could see through the whole charging that the phone wasn't drawing a stable mA throughout that it did on the 25W charger. This is done by Samsung to reduce battery temps, since they don't want another LiPo catastrophe on their hands.

[@paigow66]

Exactly! His testing needs improvement. You could clearly see the 45w charger dips under 15w a lot while the 25w charger was more stable, allowing it to catch up at around 65% battery. My 45w charger charges my s24 0-25% at 45w, 25-65% at 34w, 65-80% 22w, 80-90% 15w, 90-95w at 8w and the last 5% at 3w. This is the reason the slower charger can catch up after the battery is at 80% I charge my phone from 15-80% in 30 mins. That's what the super faster charger is for, a quick 30 min boost. 1hr charge for that last 20% is not worth.

[@Vordigon1]

​@@paigow66what improvement? Do you want him to root the devices and get rid of the logic gate keeping the battery from overheating? The test is perfect!

[@HansSchulze]

​@Vordigon1 if you blow cool air on the phone, it will not thermally throttle the charging to what seems to be 35C limit. You might have to remove cases which limit heat dissipation to get best charge. You would hope that PD would vary the charging voltage so that the phone doesn't have to DC-DC convert the voltage to what the pack needs and therefore save heat in the charging circuits. Note also that EVs charge fastest when they are close to empty, and slow down to 1/3 towards the end, even with liquid cooling.

[@raghib2954]

@@vladpaloukotis Because the phone is only drawing that much power. Just because a power supply/adapter can supply up to 45 watts doesn’t mean that’s how much the load is. The charger is in the phone, not the power supply. The charging and power management circuitry will determine how much power it can send into the battery and how much it needs to run the phone (say, if you’re using the phone and charging the battery at the same time), and it will only draw that much power from the power supply. You could plug it into a 60W or 90W USB-C laptop power supply and it wouldn’t make a difference.

[@HansSchulze]

​@@LoverOfTechis it possible that your measurement device affected the readings or added too much voltage drop (current sense resistor)? If SC2.0 modulated the voltage like latest PD3, that can affect the possibility of the voltage boost circuit kicking in to get the exact pack voltage for best current, causing extra heat in the phone (you were 35C limited on 45W and 25W).

@kalyansuman6533 yes I'm sticking with the 25w charger. A difference of around 10 mins of charging time is not big, especially since i only charge my phone about 90% to keep the battery last for years. Might also be one reason why samsung doesn't see the need to give higher charging capacity for their flagships yet, unlike many others offering up to 100+ watts

Is samsung being overly aggressive on the charge rate to control temperatures? Maybe they need to do a dual cell battery config. Great video nonetheless !

[@MZRTMusic254]

They're playing safe just like apple with higher wattage charging. Pumping more amps into a battery reduces battery life faster in the long term. Only use fast charging if you really have to.

[@Jtwizzle]

@MZRTMusic254 may be the case to an extent. Though that's playing really safe when competitors are 2-3x faster charging. Some even claim it won't effect longevity anymore than normal at those very fast charges

[@MZRTMusic254]

@Jtwizzle I'm yet to find evidence or research disproving that fast charging doesn't degrade battery life. I doubt the phone companies themselves would do it because they wouldn't make as much money advertising fast charging if it kills their batteries faster. The split battery method over higher charge input is a better choice. The tradeoff, though, is space, and that means you lose features. My sister used fast charging all the time for her Huawei phone. After 1½ years, the battery life reduced noticeably. That's fast degradation for a 5000mah battery. Normally, it would take 2 years, and even so, the degradation wouldn't be that noticeable. Even so I can't be 100% sure because there's too many factors to consider. I hope there's a breakthrough for batteries because that's what's holding back Mobile devices right now. Or at least that's what I think

[@Jtwizzle]

@MZRTMusic254 Yeah, to many factors. 1.5 years if used heavily, could be near 2 charge cycles a day. That could be a ~15% capacity loss right there. Keeping it at 100% for long periods and discharging it very low often are also not good. They generally claim that after 600-800 cycles, the battery will have 80% capacity left. I usually start to notice a drop in battery life after around a year, averaging 1 cycle a day. Definitely do need a breakthrough battery tech, hopefully soon !

[@MZRTMusic254]

I would recommend getting the FNB58 or Power-Z for measuring power consumption. The one you used is decent but not very accurate, at least according to the reviews I've read. Also, my phone supports 25w Max, but it rarely goes that high even when I'm charging from 0%. (I think Samsung likes to play it safe with charging speeds as well as Apple, unlike other brands. Faster charging speeds come at the cost of battery life too) It usually plays at 19-20W up until 60-70%, then it drops to 15-18w. At 90%, it ranges between 7-11w. At 95%, it drops to 5w. This is when I'm using a peltier cooler to keep the phone temperature at 30-33°C. Without the cooler, the wattage drops quicker at about 40-50% because the battery, CPU area, and the charging port area heat up significantly fast. CPU temperature gets to 40°C sometimes

[@eclectic_gamer]

Yep i have long suspected there was little to no difference between the 25w and 45w chargers in actual real world application thats why im still using my old 25w charger from the s9

Since I got S22U I always find 25 watts the best choice. 45W is okay for urgent stuff but problem is like you said after 30 mins or so the 45W drops down to much less so 45W is pointless after 30 mins.

I mean I can get myself one 45W to charge it in a pinch, but 25W wall charger and my 15W car charger will be just fine. Thank you!! Cheers from Croatia!!

That video is coming next so no spoilers

[@esoghumedominic13]

Great video , This phones has been locked to their designated cables. I have Huawei p30 pro with 65w cable and charger , to my greatest surprise it's slower on my note 20 ultra compared to 25 Watts charger that comes with the phone. So the problem isn't the charger but the cable. If you have higher Watts charger you also need cables that your phone is compatible with.

[@youzongliu]

Cable can be designated? I thought they just handle different wattages, how can they be phone specific. I have a 100W cable, 45w & 25w charger feels about the same to me too

[@LordGryllwotth]

Thanks! 45w barely makes sense when just getting some quick boost. But maybe if you tried starting at 20% it would matter if you just need a boost? Dunno what heat limit they have set. 40c internal?

[@rayoliver9608]

Some of the cables have like governors on them and I think they only give you a 15 watt charge cable You have to buy the 45 watt one I'm pretty sure

[@LoverOfTech]

Yes you need a 5amp cable with the 45w charger to work

[@radlrambo4994]

Same story as 5 years ago with the Note 10+ (which I currently replace by an S24U): Almost no difference in charging time when doing a complete charge (I think the diifference was 10 minutes). High Wattage can only be used if it is almost empty. But what I found astonishing were other things: 1. The Note 10+ never came even close to 45W. It maxed out at 35W and struggled to go above 30W. From the video I see that the S24U can go above 40W so this looks good to me 2. Even 25W could only be had with a special charger that can speak PPS. The 45/35W needed an even more rare PD PPS Power supply that can deliver above 3A (4A to be more precise - most Do PPS only below 3A, even if they have PD Profiles with 5A) and this also needs an active cable with an E-Marker Chip. If you use a "normal" PD Charger with fixed Profiles you are limited to 15W. I suspect this is the same with the S24U. So in reality the iphone often charges faster than the Samsung, because it can reach its 20W with any standard PD Charger or PC Port. 3. Fast charging only works with the screen off, so you cannot use it while fast charging. That can be a problem in car use. I wonder if that is the same for S24U. In reality the phone charges fast enough even with 25W - but the above limitations really are annoying (a suitable PPS Charger is hard to come by, for powerbanks it is very hard). EDIT: I have found a charging graph on the very good (though in german language) site: techtest.org/wie-schnell-laedt-das-samsung-galaxy-s24-ultra-und-welche-ladestandards-werden-unterstuetzt/ Here you can see that 45W are only reached for the first 5 minutes. Another 15 minutes at or above 30W and everything below the 23rd minute of charging are below 25W. I suspect that this is not related to the charging time per se but battery State of charge. So most of the time above 25W are never reached. EDIT No 2: Apparently Samsung got it right this time - Even with a standard PD Charger without PPS you can reach charging speeds of almost 25W (23W actually). So for the S24U you do not really need a fancy and rare PPS Charger anymore - that is a good thing and the most important Aspect IMHO. And I the other culprit is also gone now: You can happily charge fast with the screen on! My shiny new S24U currently charges with 32 Watts while the screen is on and using apps like e.g. gmail

[@LoverOfTech]

😮‍💨😮‍💨😮‍💨

[@jeffjeff644]

I have an S24U and the cable has to be the right cable for it to work or it does the same thing to mine. I use an anker 240w cable now and it does not do what happend in the test. I also tried that plug that tests for wattage, it was crashing it. It would go to 35w and then skip a beat and go back to 0w then back to 25w and then get stuck at 15w. So you have to use battery guru to see charging speed.

[@bandituga]

what is that limits the loading speed of the 45w? is the charger or the mobile phone? is it possible to test with another 45w charger like an Anker? thank you and good video.

[@LoverOfTech]

I won't be testing with another charger unless it's sponsored. It's most likely the phone

I think samsung know if they make higher W chargers the phone will get too hot and damage the battery in the long term, until samsung figure out to keep the phones at a steady temperature, they won't make the phones higher W compatibility.

Yo, samsung original cable that comes in the box is not the fastest? Should i get third party cable from UGREEN or something to get the fastest speed with my samsung 25w or either 45w brick? I always thought that the cable they included was a quality cable. Someone guide me about this please

Thanks for the comparison. I pre ordered S24 Ultra and trade it from A54, they have same 5000 mAh battery and I've been using the 25W adapter. Guess I won't need to buy the 45W adapter lol

[@LoverOfTech]

25w is all good

[@zaMPano89]

Why did you use different cables for the 25 W and 45 W chargers? Is that perhaps the reason for the difference?

[@LoverOfTech]

The white cable is a 5amp cable that is needed to get the 45w speeds

[@gabykababa9431]

The charging rate is influenced by the ambient temperature. Additionally, after reaching 50% charge, the charging rate decreases to approximately 12 watts on average. So , the 45 watt charger is useful when your battery is low , from 0 to 40%

Who is the best charger 45 w or 25 w?

[@CompatibilityMadness]

What were the exact models of chargers used ? I own EP-TA845 with (PPS) rating of "3.3-11.0V = 4.05A" and came with "5A" marked cable. EDIT : It doesn't have "X" in name.

[@LoverOfTech]

All the latest models and that is the updated 45w charger and not the old one

[@PasqualePuterio]

ESR Glass for 24 Ultra is very strong, maybe I will also try the case. I experienced some throttling with 45W original charger and cable on the 24 Ultra. My 23 Ultra takes 7 minutes more with the 25W.

[@LoverOfTech]

ESR glass and cases are great for sure

[@Hyperion1722]

You have not mentioned the USB C rating. You should choose a cable that has 5AMPS/20V rating to really check charging speed. Even a 5amps/10V rating would do nicely. In short, your cable is choked if using lower rated one - 45 watt charger is reads 4 amps while the 25w charger reads 5 amp cable. Another issue is that the phone could be restricting the current/voltage input so it is pointless to use 45watt charger as it can only accept a limited wattage. By the way, generally Samsung ultra limits charging to about 27w from 55 ot 60%, above that it charges at only 19w.

[@mirecxx22]

Why are you using USB Power Meter Testers for fast charging? In fast charging, it's important that the charger and USB cable are properly matched, as there's a small chip in the USB cable facilitating communication about specifications. Using a USB tester might interfere with this process.

[@LoverOfTech]

Of course I am using it to get the wattage reading in real time. If I don't then there will be people complaining and then when I do there is still people complaining 🤗

[@mirecxx22]

@@LoverOfTech I see, but in that case, it's better to use a power meter (in wall socket), even though it won't be entirely accurate, but it will give some estimate. ...or you should have used both variations (with and without the USB tester) during the testing.

Thanks. A question though. I get only 4v with my 25 watt charger. Never get 8-9v which I think it should?

[@NGreedia]

I was looking at the power reader on the 45w charger, and at the beginning, it was only showing 41watts briefly for like the first 5-7 minutes, but soon after, it kept fluctuating a lot to well below 20w, and wasn't giving you a consistent charge. Wondering if it might be the device, cable, or charger. 30 minutes into the test, it was bouncing between 14-30watts and levelled off at 28-30watts and then just 20watts 45 minutes into the test and just 5watts when it was around an hour. I just used the same 45 watt charger, and used the same power meter device. My 25000mah power bank just charged from 20%-99% at a continuous 42watts and didn't drop until 99% in contrast
