Question s21 ultra at 45w - Samsung Galaxy S21 Ultra

i heard s21 ultra support 45w charging.
what are the chances that samsung give us REAL 45w charging this time
and charge 80% faster than 25w ?
would be nice to charge 50% in 15 minutes, full charge in 30 minutes.

I would assume that Samsung made the 45 watt charger for the upgraded quick charge capability on the S21. I am wondering myself if it will charge faster than my S20 Ultra.

S21 series has 25W max charging.

25 watt fast charging works well... save your money.

I had been eagerly waiting for long to waste some money on a faster charger that actually works unlike useless 45W in the S20U.
The year is 2021 as per other manufacturers.

this
also faster charging basically degrades your battery life faster

My oppo find x2 Pro, charges upto 100% in 36 minutes! I don't have to worry about charging at all....

I have the Samsung Note 10 Plus which supports 45W fast charging but disabled it in the settings because charging your phone slowly is of course better for your battery.
But it is those moments when I am in a hurry and I forgot to charge my phone, then it really comes in handy. All in all 25W is probably enough.
Dont forget that you need both a cable that supports 45W charging and a 45W charging adapter.

Thats exactly whats killing your battery over time. I charge my device with 10W max over night, lower would be even better, cause you dont need the speed there. I also got a quick charger, but this is only used if im on the go and time is more important.

That is the truth 45w was supported on last gen s21 series it's gone

I got the 25w charger for my s21u because I had enough points for it. It works well, does super fast charging but if you have another decent charger you don't need it.

Yes I have one and it works fine, it works at Vooc speed I stead of super vooc,
But I only use the 50 watt charger as don't see reason to use 30

Does it really charge at 30W? I believe that would not be the case.

Yea ,I think so because Realme have vooc charge which is what some lesser phones charge at and at least for me a few .months ago it it displays charging at vooc speed as opposed to super vooc

Do you have a result of charging speed in AccuBattery for example? Could you also do a test when your phone battery is low? At such high battery the charging speed will be slow, and it will show less Amps than the maximum (and it should definitely show higher than than with the Vooc speeds). I'm not saying I don't believe you lol, but the phone might be tricking both of us showing Vooc, when it actually doesn't utilise Vooc speed.

Lol I respect that, but all I'm asking is when your battery is low next time and you connect it to the charger, just check the amps again in Ampere. And perhaps check for how long it charged in Accubattery, if you have it installed.

If your battery capacity is properly set in Accubattery, then it seems that it's charging as you would expect from the Warp charge. Just that the Amps seem low, but who knows. In the "history" tab it should show the exact duration. Thanks for testing :good:

No expert myself but it seems to be charging just as fast as my old 6T though this is a warp charge 30t charger I got off OnePlus using voucher Codes,
My 50 watt charger is the EU one and I use a eu to UK adapter with no issue.
Don't think I'll use the warp charge again as it's noticeably slower than the 50 watt,
Though the warp charge is still good 27 to 85 in 33 mins
Would probably be around 12 mins on the 50 watt
Yep that seems good. Nice job :good:

Question Can we charge S21U with 40W chargers?

Hi to all,
Can we charge S21U with 40W chargers? They are a lot chargers like Huawei, Xiaomi and etc... with 40W and more.
I believe the answer is yes - or at least probably. Most of those newer chargers are "Smart" in that they only provide the volts and amps that are needed by the device being charged. I may be wrong about that, but I don't think so - I don't think you have anything to worry about.

Pretty sure you can, I use a 45 watt "smart" charger on my NOTE 20 Ultra without any issue.
You can use any charger that supports PD (power delivery), AFC or QC2.0
Any 45 watt USBC charger out there is going to be PD standard so you'll be fine.
The downside is, it'll still only charge at 25 watts.
I am charging my s21U with an 40w charger, works without problem. not using 40 watts of course, but its working.
The phone, all phones in fact, will ONLY charge at it's highest speed the phone allows itself to receive, the charger doesn't matter, it can be lower or higher than what the device is recommended for. A lower power charger will just take longer to charge the phone, a higher power charger will just not charge at it's full power if the phone won't accept the full power from the charger.
I've been using the 90w charger from my HP Spectre X360 my S20 Ultra since I got it without a single issue, I still get about 2 days of use per charge on that thing, and now I've been using the same laptop charger on the S21 Ultra and it works just fine.
The phone fast charges normally, doesn't get super hot, works just fine, and I only need to keep laptop chargers around the house, it's great haha
I have a 45W USB-C PD port as part of an Anker PowerPort and also the 18W charger that came with my Pixel 5. Would I notice much of an improvement in charging speed or integrity/longevity of the battery by purchasing Samsung's 25W charger?

That's the charger I've been using w/ S21Ultra (25W from N10+) and I figured out I won't be needing anything bigger then that. Thanks to Samsung 'super fast charging' the 5Ah battery on s21U charges faster then 3.8mA Pixel 4a5G battery(with the same charger). +/- 1 hour and done!

Doubt about fast charge

Hello friends. I've just bought a S20 FE Snapdragon to my wife but I have a doubt about fast charge.
My 18W Quick Charge 3.0 and my 27W Quick Charge 4.0 don't work as I wished. They just do a normal charge.
I've read that Exynos Edition uses Samsung 25W charger, but what about the Snapdragon edition? Does it use this 25W charger? What about the 45W charger?
Thank you guys.
yes it supports up to 25watt charging, you have to turn it on yourself if it's not activated.
battery and device care / battery / more battery settings / enable fast charge

Thank you for the reply. I've search it and it's enabled by default. I tried an Aukey Quick Charge 3.0 18 W and worked. It says it's fast charge. It's not stellar but way better than 2+ hours.
even without fast charging I don't wait 2 hours

I didn't try the 15w charger that comes in the box. What I think that was weird was my 27W Xiaomi charger charging with the time beyond two hours until it finishes.
Do you know if the 45W charger works?
nothing above 25watts will work any faster, the maximum current draw is 25watts if it works at all. not all fast chargers do work properly, that might explain your Xiaomi 2hrs plus.
the phone and the charger need to be able to communicate with each other / be running on the same standard.

Yes man. That's even sad because they put a beast like a Snapdragon 865 on it.
I am satisfied with original 15W charger: 11%~100% in 1h20m is decent speed and at the same time low stress for battery.

True. I just bought a Samsung 25W super fast charge to my Snapdragon 865 and worked. I'll buy one for my father that uses an Exynos SoC too. It's sad to spend money with something like that.
I use the Samsung 20 w brick. When fast charging it get about 2%@minute.
Fast charging will not engage if the start temperature is too low or high.
If the battery has failed*.
Fast charging ramps down at around 80% to slow charging or if battery temperature goes to high. If temperature continues to climb above 102 F or so it will disengage entirely and end that charge cycle.
After 90% the charge rate crawls at as little as 1%@2 minutes.
* check for rear cover bulging. A battery can fail at any time but it's more likely to happen in an older degraded cell. Failures can happen fast, replaced asap, like that same day, if this happens. It can destroy the phone.

Question Best charger/wattage for best battery life span

Hello people I recently acquired my 11t pro and I know that the 120w charging, first it's amazing, but second it's kind of concerning to think that such a charging speed might not wear down the battery life even though Xiaomi claims 800 cycles and a bunch of certifications.
So I've decided to only use 120w on hasty situations or while traveling, etc. And I happen to have different xiaomi chargers.
The question is which do you think is the best wattage or charger to make battery life span longer 22.5w or 33w?
(wish I had the 67w from the 11t, but unfortunately I don't)
You're correct. Fast charging is poison for battery lifespan, of course the device makers love that because $. As low and slow as possible is the way to go, 18-25 W as a good trade off I would say. Some, including myself go even lower.
yeah,I haven't tested the 11t pro but with a redmi note 9 using a samsung note 9 charger it looked like the redmi wasn't getting any charge up. So that low is good?
i use 12/15w and its perfect !
Im charging mine with standard 5v 2A (its slow, but i thing battery will have better life down the line) since im planning to use my phone for 4-5 years minimum (last phone oneplus 2 was in use 6 years)

Yes, you are right, when you are not in hurry i dont see reason not to use slower speed charging and then if you need speed use fast charger once in awhile
Well just as an addition I've tested several chargers with different wattages and these are the results in terms of time:
Samsung 10w - 2h:40min ±
Xiaomi 18w - 1h 30min ±
Xiaomi 22.5w - 1h 05min ±
Xiaomi 33w - 50 min ±
Xiaomi 120w 17 min at least for me.
Charging from around 10 to 100%
I am using Samsung 15W charger, around 2h to fully charge the phone.
I use a 33W charger from my K30 Pro Zoom. I charge from 20% remaining to 90% in 30 mins. Probably 45 mins if totally drained but never have to wait for an hour to fully charge. I only use 120W during business trips or Out of town.
By the way, your cord needs to match the type of Charger you are using or you'll just end up with a bottle neck charging.
I think the best option would be 65W, either mi charger or anker. Im currently using anker 65w charger, and oh my god, im getting a beautiful battery life of upto 8 hours sot on heavy usage. And by heavy usage i mean, streaming, maps.
With heavy games as well, its a bit lower. But charging with 120W affects the battery negatively. And i think it doesnt charge it completely even though it shows 100%.

Question Which charger (with cable) will charge the S23 (not + or Ultra) the fastest?

Which charger (with cable) will charge the S23 (not + or Ultra) the fastest?
Use the OEM Samsung cable/brick.
There is no OEM one, no? As in the box. btw it supports max 25W so the "Samsung 25W PD Adapter"

Samsung went chintzy with all the "extras" like a brick/cable in the box. The N10+ came with them.
So... yeah buy the OEM Samsung 25W charging set. It's actually a high quality pair. My original set is still tight and running good after almost 4 years and thousands of charges.
Don't roll up the cable once unpacked to prolong its lifespan.
Thank you for your responses!
I ended up giving these a go, and they charge my S23 from 1% to 100% in less than 1h and 15 minutes (I even a few things on the phone while charging).

I use the ''Ambrane 45W Fast Charger'' with cable that came along the phone and have been very satisfied (using device & charger since 24 Feb). Charges the phone from 0-100 in about 40 mins (0-85 in around 30mins). The phone has a "superfast charging" feature very few know about and correct cable/pd bricks do this trick.
What is Samsung Super Fast Charging?
Samsung's Super Fast Charging offers up to 45W of charging power, but you can't expect the same performance on every device.

Not sure why it says that, maybe 25W max with the normal fast adapters and not the adaptive/power delivery adapters. I get a superfast charging text/ teal colored ring when I switch on the toggle for fast charging and green ring/charging text when it's off.

1850 mA max output otherwise
Hopefully, someone with a better knowledge might be able to help us out!
