If you preorder then you might as well get it since you get the credit. However I see little benefit to purchasing the 45w charger separately especially if you are coming from an older Samsung phone and already have the 25w charger
After a phone is charged to 80%, no matter how fast the charger is, the charge will relatively slow down. That is why the gap was reduced between 80% and 88%. Because the 45-watt charger had crossed the 80% mark and had reduced its speed, while the 25watt charger was pumping full juice till it reached 80%. Also, the 45-watt charger is significantly better if you want to top up enough for the phone to run for the day or half a day at least while you have a shower. That charging speed for the first 60% matters the most, and that is where there is a clear advantage. I know the end result showed that it was only 8 minutes, but just want you to realise, that 8 minutes is a really, really long time. The ideal speed test for a charger should be done from 15% to 80%. That is where the 45-watt charger will shine. Also, thanks for the information about the thicker chord needed in the 45-watt charger! I had no idea about it. You saved me a lot of money lol.
The 45W doesn't charge 45/25 times as fast as the 25W one, but it's still noticeably faster in the middle ranges. It's the cost difference or situational utility that would determine which I would purchase. The 45W was about £9 more or something when I bought it so thought to give it a shot, and not disappointed.
USB C and charger protocol like PPS, PD 3.0 here. Phone comunicate the best power they need and power brick bring that just need power. The output charge 45 watt, 75 watt just peak power maximum but if the battery almost full. Big juice in small space that battery for electron can't accept that power and temp. So the power peak lower if battery almost full to protect battery.
@@Invertedzero When I use app Ampere to test the charging current for my 25w charger, I got 4200mA. That's much higher than the advertised up to 3A current. What's the charging current for 45w charger?
I went from a 15w charger to a 25w charger and saw a 20 min difference definitely happy with my purchase and I love the 20 min cut down time makes a huge difference.
I had a 10 watt charger that toke 2 hours and 9 mins. Just got the 25 watt samsung charger for 15 bucks on Amazon and now it only takes an hour an 9 mins to charge. Definitely worth it💯. And Definitely not worth spending 40 bucks on the 45 watt charger.
25w compared to 45w doesn't even make that big of a difference, only 10 minutes max. Your 15w charger was probably just fake and was a regular slow 5v charger. Most pd chargers are 20w minimum, so 15w already sounds like a made up number for a fast charger.
@@flyingtentacle7631 my 15w charger came with my s10+ thank you very much so i dont believe that samsung would give me a fake 15w charger and the 25w charger that i bought is also from samsung. i will say tho enabling super fast charging makes my 25w charger go all the way to 37w which is insane (I only know this cause when i was on holiday i plugged in my charger into a powerbrick that has a plug socket and the output said 37w) plus my dad spent like 200-300 in that power brick which also has solar panels to then recharge the powerbrick it's pretty awesome the power brick/bank is the jackery explorer 240 portable power station
@@flyingtentacle7631 bruh the S10+ came out in 2019 that was when iPhones where stuck on 5w charging and a lot of androids still shipped with 15w charging however 25w charging was starting to become a thing with the S10 5G which was the first Samsung device to support 25w's. 15w charging I believe came with the s8 then s9 and S10 and it's been around for a long time at least on Android phones. Now apple has only supported 2 types of Charing 5w and 20w so obviously if you have only used an iPhone you would call 15w charging fake because iPhones have never had that speed before. 15w charging has been around for a long ass time and it's still used on midrange phones and budget phones since it uses usb2.0 port and type A to type C instead of usb c to usb c. Maybe next time do some research before making up bullshit like 15w charging Is fake.
The only time you would even get that slight boost is if you let your phone drain below 15%. Anything more then that and it only charges around 22 watts.
Can you do another charging test where the charging starts when phones have just entered power saving mode (15% battery)?! Because I believe that is how most of the people actually charge their phone! Another real world yet reasonable factor added to the test!
@@afiqaFaT Yeah! Because if you're saying that the output drops to 29W after 25%, the difference would be 10% and 15W and then 4W thereafter! Doubt it'd be much!
I have a Nissan Leaf and it will charge very slowly if allowed to drop below 15%. But charge it at 30 or 40% and it will charge faster than all get out. Yes, I agree. Rerun the test starting out at higher percentages
I am more interested in heat during charging. I know that heat is the battery killer. I would imagine that slightly faster speed is not worth the degradation of that lithium ion battery. I would be interested to hear how much that shortened the life of that battery. It won't be a small difference. I would guess that using the phone while charging GREATLY increases heat. This is why they don't allow the fast charging while using it. Smart honestly.
batteries are rated to last minimum 800 charges and remain above 80% capacity. That is the industry standard. Modern phones will throttle charging wattage to keep the temps in check If you change your phone every 2-3 years, you don't have to worry about battery degradation.
Well 8T uses dual battery design. So 65 watt divided by 2 battery 32.5 watt each. Its not hot while charging. Previous versions already used 30watt. It doubled that in 2020.
Every samsung phones can only take 25w charging whatever the charger power. If you plug your samsung on a 100w charger it will still charge at 25w. This is why the difference is so tiny between 25w and 45w charger.
I see the benefits in the 45w for travelers. If I'm out and about all day and come back to the hotel to change or shower, etc. for a dinner event, or even in times where I simply have just 10-15 minutes to get ready for my evening, the 45w charger will shine more there. HOnestly, both work fine as I do this now with a 25w charger but now that I'm out to buy a new / another one, I'm going to pick one up and keep it and the thicker cable in my bag.
I noticed almost the same thing when charging. I took my phone down to 15% charge and never say more then 30w. Most of the time it stayed around 22w. While I'm fine with the charging time, I think Samsung should be held accountable for their lie. Lots of people will spend their money on 45w+ chargers because of Samsung's lie.
@@aliendroneservices6621 I don't think that is correct but since this post it appears that Samsung limits the charging wattage on all but a brand new charger that they are just releasing. If that is correct.... kind of shitty to advertise a phone that will charge at 45 watts... but it won't with any 45 watt charger except one that will be released.
Charging rate depends on the battery temperature and the state of charge. It depends on how Samsung implements that. Also, even if it can charge at 1C (45W), it might have been limited to 0.9C. Also the maximum charge rate might be when the battery temperature is at 25C-35C and less than 50%, that is why you see lesser speeds while gaming. Guess Samsung is taking care of the battery health.
@@user-xi7lg3em8i No need to, they would have already tested it across temperatures so that you don't have to use your brain more than just for commenting.
I currently have a 15w one to my s8, so the 45w will be a huge jump, even if it’s more like 30w, perks of stretching old hardware I also think 0-50 is more important for fast characters, if you have 75% you don’t need to emergency charge, like you might at 5%
Phone makers are still struggling at charging batteries from 0 to 100% at full speed without damaging the cells. 62 minutes to fully charge a 5000 mAh battery is already a great outcome. and 15 minutes to get 32% of charge sounds great to me.
@@DENVEROUTDOORMAN actually they don't. I use Xiaomi and Samsung phone, regularly and Xiaomi phones maintain their battery health just as long as Samsung does and I use 120W charging on my Xiaomi, every single day.
I think there is a difference in technology also! Samsung, Apple and Google use li-ion and xiaomi, oneplus use li-po. Li-po can take much more current to charge very fast, but it degrades much faster also. I still use 1A(5W) charger to charge trough the night and fast charger only in emergency situations.
Just asking, because I recently discovered in Andriod 12 that some of my superfast wired charging and fast wireless charging had settings and I had most of them off. How that happened, not sure. But result was wireless and fast wireless charging were the same. Until I enabled them. Pushing charge into batteries tends to reduce thier life so even the superfast modes moderate chagring rare near a fully charged state or as mentioned in comments when warm. Any chance you didn't have the newer faster charging enabled on the phones?
yeah all comparison so far doesn't make a distinction. perhaps the new charger actually charges it faster? i know that it's actually coming out in a few weeks though
@Kaban Galeri Yeah I think so too. It should be different from than previous one. Otherwise it doesn't make any sense for Samsung to support 45W again if its the same.
@@IndianGagdgetGuy the problem is no one from samsung clarifies this issue, they are getting a loy of bad press lately especially with the ltpo blunder on the s22 and s22 plus
For those who are concidering buying the 45w charger and want to save a euro or two,I suggest looking up the 25w one. Atleast where I live the 45w white one costs ~20eur ,black ~30eur and the 25w black/white ~11eur. Dunno if this helps,just wanted to mention it! Thanks for the video PhoneArena!
I don't regret buying a 45w charger, 'cause their purpose are different. I use the 25w that came in tha box to charge at night, when I won't need the phone for hours, and the 45w to a quick refuel in the middle of the day. A bonus point: my 45w charger has a 1.80m cable.
This is basically the same result like in 2019 with Note 10 as in the 45W is only slightly quicker than the 25W. Even after years, Samsung still have that Note 7 phobia and just playing it safe for now. Can't blame them though since getting more than 50% in 30 minutes is pretty good. Can't beat the Chinese phones crazy charging speed though.
I love my S22 ultra but it's annoying that it takes an hour to charge. My last mobile was Oppo Find X2 Pro and it charged in about an 32 minutes and Oppo included the brick in the box too. Why is Samsung behind in this area ???
@@Moon222 My s22 ultra didn't come with a charger either so I'm using my 65 watt supervooc Oppo charger and it takes about an hour and half to charge from 0% to 100%. Fast charging is a big thing when choosing a mobile and i can honestly say that I'm regretting buying my s22 ultra. Best phone money can buy and I'm really disappointed with it in so many ways.
Since my last comment, I've recently bought the 45 watt Samsung charger and it's considerably better than the 25 watt Samsung charger. Only paid 25 quid for it too. It's definitely worth paying the little extra for the 45 watt instead of the 25 watt. However, they are still half the speed of my old Oppo Find X2 Pro with its 65 watt SuperVooc charger which comes in the box.
Can you confirm if you used the new 45W brick or the old one please? The new TP-4510 is said to address some of the throttling issues with the older one.
I have a charger from my S8 Plus, I used this charger on my new S22 Ultra, battery on 50% 21 minutes later 100% - When I connected the S22 Ultra a message popped up, if I wanted to select regular or fast charging; I selected fast charging, not too shabby 50% in 21 minutes.
Some of the information towards the end of this video is a bit misleading. The way charging phones works, especially with higher wattage chargers, is basically based on how full the battery is. As batteries get more full, charging speeds/wattages drop. This is inevitable. If you were to create a graph of battery percentage x charger wattage, you would see a consistent drop off or diminishing returns of wattage as battery percentage increases. This is true for any charger of any wattage. I do completely agree that 45W charging is at best a nice to have over a 25 watt charger, given the small real gains, but the majority of the advantage you will see comes from the lower percentage charging (say, charging from 0-50%), given those battery percentages are where you will actually be able to achieve the higher wattage values. It's not that samsung or any other company is lying per se about the charging speeds or power outputs, but more accurately that the science behind chargers and batteries restricts them in this way. For now, this is how batteries and charging is limited, and until entirely new technology comes along, this is how it will be.
Great video!! I downloaded a current measuring App that says my multi-port charger provides 1,700 ma to the S22 Ultra with a standard cable. 1. I would LOVE to see an accuracy comparison between your Power Meter current readings and a couple of the current measuring Apps. 2. Thanks for the heads up that a 5 amp charging cable is available. I ordered one to be delivered tomorrow and it's going to be fun comparing current supplied with that cable to the S22 Ultra provided cable and several other C to C cables I already have.
So basically, Huawei P30 Pro released 3 years ago (26 March, 2019) with the first 40w charger seems much faster, because the 45w charger unexpectedly loses a lot of momentum at the end and never delivers more than 40w.
I have the 40 watt charger for my P30 pro. Will this work well to charge my new S22 Ultra? I really don't want to shell out for another charger. Thanks
They're slower because they use the Power Delivery standard, which is not as efficient as Oppo's VOOC standard. Oppo/OnePlus's charging actually generate LESS heat, so they're able to charge faster.
you are confusing charging protocols with efficiency. the efficiency is in the charger, cable, BMS and battery. BBK just dumps several amps into the battery and calls it a day. Oneplus states on their 65W charger 84.88% efficiency, Anker 65W Nano is rated at 87.74% = barely any difference. In the end it´s phones we are comparing with tiny batteries (in comparison to EVs).
You should learn more about what happens when battery gets to above 80%. But of course you don't and just continue crying about it. Also you should only charge to around 80-85%. Your phone has setting you can enable to do that. Why? Because of reason you don't want to learn about.
@@edwts Wrong. It will charge exactly at speed battery tells it to. You're yet another whining karen who who refuses to learn how charging and more precisely fast charging works and why it doesn't every time.
The first useful comparison i see in the internet Just 8 minutes difference that is not worth it of course I can use my old 25 w charger if that is the case
Honestly. I'm sticking with the 25 watt because there is not really to much of a difference. Now if that was a 100 watt wall charger "which I don't expect to see until the next ultra or even 2 after that" that is when it's going to really matter but for now personally I would stick the 25 watt.
Using a battery with a higher Watt too often will just accelerate the damage to the phone battery. Since the very old age, Companies tend to lie to customers when it comes to Number. Besides, it's understandable that technically most companies usually play safe, in which the capabilities of their electric device products wont be boosted and optimalized to the top level they actually can reach to avoid early damage of the device. Fortunately, that can make the device last longer.
Samsung is using proprietary charger for their devices, the fast charging won't work if you using different charger brand(or not listed in their official supported fast charger) and vice versa
@@kton3613 would the 45w charger from spigen work? I've seen people getting the super fast charging 2.0 with it, that's why I'm unsure of what's gonna happen with my Xiaomi charger. As long as it's fast charging I'm cool with it.
Nice & detailed informative video. Thank You! 🙂👍🏻🙏🏼 I pre-ordered S22-U and asked for 45W Charger offline. Lucky me, it wasn't available in Samsung Store, so I decided to buy the cheaper but competitive 25W battery.
Superfast charging 2.0 is not working on my S22 ultra. I have a 65W PPS charger which is able to charge my galaxy tab S7+ at 2.0 but for some reason it is only able to charge my phone at Superfast charging (and not at 2.0). Settings are turned on. Does anyone know what's the issue?
Second note. I think samsung doesnt utilize the super fast charge like oneplus simply to save battery life expectancies. Lithium doesnt like to be fast charged all the time. It will fail sooner if continuously charging fast. They need a "trickle" charge to save its life expectancy.
Your exactly right, and it was obvious from the beginning, two of the biggest phone brands are using low charge speed compared to others. They can copy it if they wanted to, but iPhones and the galaxy s series are known to last years on end without any issues, and it seems they want to keep it that way.
The ONLY channel that does DEEP DIVES into the S22Ultra ! All the other big channels seem to shun the truth .. All doing the same lame reviews with an unboxing, show the device (we have seen it a 1000 times), detail camera testing and then a game or 2 and maybe a quick benchmark, that's it ... People want to know True performance True reallife battery stamina And real comparisons ! It's remarkable how 'soft' the other channels are and none of them seem to want to ay anything bad about this device .....
Samsung is the gift that keeps on giving for YT creators, a conveyor belt of cash on every release; so we get something out of the Twilight Zone where they obfuscate anything that is not so great. Stuff like no AV1 support on media streaming on the SD8G1 when the Exynos 2100 had it in the S21U! The chips can handle that codec with ease as Samsung shows, yet no feedback to Qualcomm to get support? Do not want to upset Qualcomm and the free trips to their showcases! YT is the place for technical comparisons, to question decisions, but it seems it is more about pleasing the clients, be it Samsung/Qualcomm fans or the businesses!
Sergio Casino You're kidding me right? There are TONS of channels who reviewed S22 series and some of them pointed a couple of issues (mainly battery life). Do you live in North Korea or something? You only have access to 2 channels? Or are you just crappy at searching? You're also gullible. This video uses the OLD Samsung 45w charger which was already known to have issues. This video should also test the newest Samsung 45W charger then make their conclusions. Why test new hardware with old hardware? Test new hardware with new hardware that came out at the same time. Just shows this channel doesn't know how to properly test things. Do us all and yourself a favor and do your research before spewing garbage for everyone to see.
@@HDGuy001 Name me 3 million + subs channels that went into detail about the battery life and real performance. Saying that you got through the day is not enough. That doesn't say shit. A proper test of anything is a video on itself and not just showing a benchmark after doing a 10 minute unbox and talking about the camera. Again, show me a channel that shows an extensive batterytest of the Exy 2200 and 8gen1 so we can compare.
@@Roomer645 I'm assuming you're an adult right? You don't know how to search yourself? Deep Dive? Real comparisons? How many tests did he do? ONE test recording the charging time? How many chargers did he use? 2 Samsung chargers? What about chargers from other companies? What about chargers without PD? What about chargers that are > 45W? Chargers < 25W? What about comparing Exynos and Snapdragon charging times? The list goes on and on in addition to using the OLD 45W charger instead of the new one! Like I was saying before he did NOT TEST PROPERLY and left out important information that will confuse viewers. Also as you can see from the comments below many people are saying there's no point using the 45w charger which means the damage is already done. Others are telling him to test using the newer charger. So you think it's OK to mislead the public when a channel did not present all the information? PS - It takes time to thoroughly test everything and some channels just do an initial first look. Not to mention soon after release date, sometimes Samsung will push out their final software updates.
is it the same 45 watt charger that samsung released with note 10 series? or they have a new one in 2022? I have the old 45 watt brick, can I expect this kind of performance with that or need to go for aa new one?
if you zoom at 8:06 you can notice that it's the TA845, the old 45w charger not the T4510 that was released with the s22. UT aside of being smaller in size, the specs are identical between the two so am not sure if the newer model would matter. but in this video, its the old one
The chinese use dual cell batteries, so it can top up in a safe pace. ie, if it's a 4000mah cell with 120w charge, it's cell is split into 2k each and charged at 60w per side.
Thank you for this video ! I read everyehere that your charger has to be of the samer brand of your phone. Vut let's say you have a good third part quick charger (Anker, Spigen) Still not recommendable or no issues about using one of those ?
@@kona328WH Yeah I bought this charger yesterday from Amazon and when tested on my current S20 Ultra it would only charge at Superfast and not 2.0 so in effect, it would only reach 25w. So I sent it back. I've now ordered the Anker 45w to test, before my S22 Ultra arrives.
If you’re an insane power user I’d say it’s worth it. Charging quickly in short bursts is nice. The average person will be fine with the 25W/30W. I’ll keep my 30W Anker Nano II.
45 w is better in gaming experience, while you gaming and charging phone in same time it will produce less heat and will be more comfortable while playing while 25 w will have more pressure on it. My opinion
At start, it showed the time difference to 100% being 8 minutes so you only need the "better" charger if you need a quick top-up but otherwise, meh. No VooC charge
Samsung claims that s21u supports 25W fast charge， but actually ，when you're using a pd charger that supports 3A PPS，the maximum charging speed can go up to 27W and it maintains the speed until the phone is charged up to about 70-80% ，this is interesting
thanks I continue with my 25w charger since the truth is that the big change is in the first half hour, from there plus 10 minutes of difference I better continue with the 25w one thanks you made me save money
Very good testing and correct, the first time to see someone to show charging speeds when the screen is on, unfortunately there is one guy who only says the charger is old one, it's the same charger kiddo like what Samsung use from S4 to S10 15W charger with different letters and numbers, next time GJNA ask Samsung to pay you more for your comments. I am still using this kind of tester for power and is very good, good job mate!
Hi, Once in a while I charge my phones via USB multimeter (USB OLED display tester J7-4T) on the same charging voltage/same charger so I can see the deterioration going on in my batteries/phones/etc. So, my old Galaxy S7 flat (3000mAh battery) when it was about a half a year old it could take slightly over 2100mAh, few days ago and yesterday (as I repeat the test for more reliability) it can take only just above 1500mAh. My Galaxy s20 with battery stated 4000mAH it can take just over 2000mAh- I do not know how much it could take when device was new as I bought it used. IMHO no app can tell you more and better than this kind of test. If I'm wrong correct me guys ;) Can you do some tests this way- with USB multimeter- for brand new phones and then compare it with used (a year or two) same phones? What do you think?
The drop in wattage after the initial 45W is to preserve longevity in the phones battery. If the battery is always being slammed with 45W it will degrade significantly faster.
How can I calculate what charger I have? I have the Samsung S21 ultra charger which has printed on it, 9v and 1.67 amps. That doesn't equal 25 watts. Am I calculating it wrong or do I just not have the 25 watt charger?
I have a 30w pps from google and it’s a real sweet spot. I’m really amazed at how cool pps charging keeps the phones. I was using a 20w apple charger and it is way hotter.
I had the S21 and now have the S22 Ultra. must say I love this phone its awesome. So premium and feels good. Its just a very heavy phone so laying in bed using it my fingers feel the weight. But yea my 25w charger charges this phone very fast. Much faster than the S21. I wanted the 45w charger but honestly I dont see it worth the money right now. The 25w does a very good job at the moment. So Ill save the 35 euros for now.
It protects the battery. The faster a battery charges the life of the battery is basically cut in half. That's the reason the big companies do it, for longer life of the battery. They are looking out for the customer.
Put the phone under cold control temperatures, ie inside the fridge, and it would pull more wattage, chargers have temperature sensors that would slightly reduce wattage for safety
Good choice to use false advertising and use a worse charging protocol than nearly every competitor, a protocol that generates more heat and kills batteries faster.
@@st3yn how exactly did you imagine a protocol creating heat? It's just electrons following, they don't give a fuck how the phone and charger agreed on a voltage and current. Ohms law is the only thing that matters
To be fair people are looking at it wrong looking at percentage difference. 10% is about 2 hours use so in 30 minutes you get 2 hours extra battery time than the normal charge perfect for when you are in a rush. Which is the whole point of the fast charge. You shouldn't be using it except in emergencies anyway because it kills the battery life of the phone over time.
The graph around 4:30 was kind of misleading showing the showing inequal gaps of time equally spaced out I know it's meant to show the difference between the two but it makes it look like the fastest charging happened in the middle.
