Charging thoughts.

I just got this wonderful phone, but there are some mysteries that I would like to get solved. Mostly, they are about charging. I would like to use wireless charging, but most QI chargers only deliver 600-1000 MAh. If it delivers 1000 MAh and the power conversion rate is set by manufacturer to 70%, does that mean that it only charges with 700 MAh?? That way it will take 4.5 hours for it to charge from 0-100%. BUT... my original wall charger shows appx 700 MAh when I check it with the pro version of the app Galaxy Charging Current and the pro version of Ampere. The phone says the phone is done charging in appx 1.5 hours. What decides the rate of charging?? I have tried a LOT of chargers, even the now leftover charger from my Galaxy S4, but they don't charge as fast. Some of my USB wall chargers take over 3 hours to get the job done, and I would like a spare that does it as good as the original. There are som 3 Ampere chargeres on ebay, are any of them any good? Hope to get this clarifyed.

Hi,
Which phone? Kindly provide us the more details.

My phone
What? You are not psychic?? ;=) My bad, I thought I posted this in the Galaxy S7 forum, but must have been sleepy. Like I wrote, it is a Samsung Galaxy S7. Sorry for the slip.

FAST Wireless Charger [third party] with Note 9

I recently buy third party Wireless charger Baseus 10W, but I have problem with it. When I connect it to original Note 9 Charger it won't charge in Fast mode only standard. I little research and find thet older samsung chargers (Galaxy S7...) are work without problem with Fast Wireless Charging.
Note 9 use Charger EP-TA20EBE, if you want to use third party Wireless Chargers use EP-TA20EWE.
I made short video about Baseus Wireless Charger its cheap and very good, its have Fast Charging mod. If you are interested you can check video:

RavPower B0792VBPLV
Bought this one a week ago; https://www.amazon.de/gp/product/B0792VBPLV/
It's perfect. Charges really fast, includes its own 24W plugged power-supply. Came highly recommended by a friend who also has this exact same model ravpower and a note 8. Loving it so far.

How long do you mean by "really fast"? I have an ADATA CW0100 pad and it won't consistently fast-charge with the Note 9's power brick but works fine with my Sony UCH10 QC.20 charger. It still takes about 3 hours to reach maximum capacity.

I don't own an ADATA pad, so how should I know?
My Note 9 (4023 mAh estimated battery capacity, according to AccuBattery Pro) on average charges to 54% in less than an hour. I consider that fast. By the way, depending on the type battery, but most current batteries don't benefit from charging to the full 100%. With AccuBattery you can find out the sweet spot for your device's battery life, for mine that was around 56%, so I rarely charge it higher than that.

General Well. This is a bit disappointing

S22 Ultra 45W vs S22 Ultra 25W vs S21 Ultra 25W charging test

wouldve expected it to charge much faster, especially when you consider the smaller battery.

Totally expected, 45W works just at lower temperatures and under 50% charge as it was back in the Note 10+ days. It's useful only when you are topping up on the go, for 0-100% it's almost the same

Why expected? That was for previous models. Battery charging could have been improved on this phone too.

Well it is improved, it was downgraded 2 years ago to be fair and now is back to that state. It charges faster from 0% to 50% which is exactly how it used to work before. If you expected something different your expectations were wrong, don't know what to say. Even devices with very fast charge charge faster for the first half then slow down considerably. Samsung has always had a more conservative approach on charging after the Note 7 debacle, that's why I expected it to be managed like it was before.

I've traded my Oneplus 7 pro. A 3 year old phone and It still charges much faster than S22 Ultra. Considering to I'm paying for a flagship phone which is over £1000 and it's charging technology called "Super fast" charging. Yeah I'm a bit disappointed.

The N10+ with the 25w brick will fast charge from 5-70% at the rate of 2%@min on its 4300mAh battery. Between 70-82% it may ramp down slightly, at 90% fast charging disengages.
This is dependent on battery start charging temperature, if too low or high fast charging will not engage, and battery condition. A 20% charge in 10 minutes isn't bad...
Fast charging is limited by heat buildup in the battery caused by internal resistance. The Li cell charging process is actually an endothermic reaction but is outweighed by the internal resistance generated heat.

I can see it being an issue for those that prioritize fast charging over battery longevity. I charge my device overnight and use a Chargie to regulate the charge to a maximum of 80% and limited to 8 watts. I'm not a power user and this method may not work for everyone.

Looks like they're using an older 45 watter. The new ones are the real 45 watts.

I heard that was the case. The old 45W charger throttled, making it act like a 25W charger. The new one has PPS and is PD 3.0?

The old 45 Watt averaged about 28 watts of power iirc. The new one will supposedly give the full advertised wattage. I'm just shocked sammobile out of all sites did not know this...

That is shocking. Do you think the new charger will output less heat to the S22 Ultra because of better efficiency thanks to PPS?

I doubt it. QC boosts the charge wattage by increasing the voltage; more volts less amps means less parasitic waste heat.
What's left to improve on the charging protocol side? They to improve the battery itself now for any meaningful performance improvements.
These manufacturers push the hype, the reviewers do too, then long after the release the truth finally comes out.
If you can wait a few months for the dust to settle you'll get a better idea of what to expect.

There is a new 45w charger, model EP-T4510XBEGGB. This one seems to work fine and not overheat.

Curious as to what your thoughts are regarding the Chargie since Samsung has now added the same charge up to 80% feature in Android 12 under device care. Is it now redundant?

i have those USB-C cable with watt LED display. it only showing 31w on my home 65w aftermarket charger,
also showing only 31w on my 65w aftermarket car charger.

I'm using my OP9P charger lol it works really fast so...I didn't need to buy a separate charger. Thank God since it's sold out

Question Why does the wireless charging suck so bad on this Device?

I am on the second Snapdragon ATT device and wireless charging is the worst I had in years. I dont know if its a software issue that can be fixed or a hardware issue. Both devices exhibit the same issue slow wireless charging or no charging at all just gets hot. I dont get it brand new phone thinking about going to last years S21 ULTRA if they give me the trade in credit. I have a note 20 ultra and it charges wirelessly just fine on any Qi charger. So disappointed right now.

I got this one. 15 watt wireless it's a 25 watt super fast charger so if you need a quicker charge you can always connect the phone directly without the pad. Both work great! Don't need that 45 watt charger this is perfect for wireless and wired.

Well I guess so if you having problems. Mine is the U.S. 512 gb Black version.
15 watt wireless and 25 watt wired.

Kept mine overnight with a 9W wireless charger and went from 2% to 21% over 8 hours...

Are you charging with the case on or off? I have been using my old Pixel wall charger and the OG Pixel stand. Plugged in my S22U chares quickly. If I use the Pixel stand it only charges with the case removed.

It could be the phone case, but, its not constant, I mean a day or two will charge full battery in 4 hrs aprox, like it should be, some other days 20% in 8 hours or so.. and its the same phone case

Mine charges Wirelessly in an hour. Snap Dragon 512gb Unlocked. Case is OtterBox Defender Pro and Charger is this one. If you do buy this one make sure you buy this exact model and not the one listed for $39.99 because that one only comes with a cable. The $59.99 one comes with cable and a 25 watt super fast charger. Will charge wirelessly at 15 watts or wired at 25 watts.

Sigh. I just double checked my preorder and this is what I have coming. Just like the review complaints, when I placed my order it had a picture of an adapter next to the charger so I logically assumed it was included. Now I see that they have 'updated' the product description to state that it is not included and I believe that was retroactively added because of all the negative reviews about this omission.
If I use one of the older 25 watt adapters that came with my Note 20 ultra, will it still work? I don't need it to fast charge. If regular charging takes a little over 2 hours from 0-100 with the phone plugged into the 25 watt adapter to a wall outlet- how much more longer do you think it will take to charge my yet to be shipped t-mobile S22 Ultra with this wireless charger?

General Charging the device feels very slow - Exynos

Hello, 4 days ago I bought this new s22 ultra with exynos processor, but it is generating many doubts that the loading of the device I feel that it is going very slow or more than it should be.
It always takes 2 1/2 hours or more to charge 100% with a 47w essenger charger or a Samsung charger that I have from the s10+ which I think is 20w and 3a
Measuring the charging speed in a plant or portable battery that I always have mark at most 20w but never stays at that speed, usually oscillates a lot between 10 and 16w, and stays much more at 10w which makes me weird and annoying because it is very low
I do not know if I should buy a Samsung charger of 25w since from what I have seen the 45w charge does not work, and that charger would be 5A unlike the one I have that is 3A but I do not know if it would make any difference.
I would like to know if it happens to someone else or if it is something normal, this makes me think a lot about changing phones since the charge seems to be very slow.
Please would appreciate any help, I will also leave attached the charging settings I have placed and the measurement I have made with my charger, I serve any advice you have please

Charges fine (inc. super fast) with Samsung charger ex Note 20

I have Samsung (i think 25w charger) and from 10% to 100% Max 1h10 mins

45w charges quick enough

It's a QuickCharge 3. It's an old standard for Snapdragon phones and Samsung S-series before s20. To charge fast You need 45W PPS PD 3.0 charger. PPS is crucial.

If i remember correct samsung 45watt charging is 9v x 5A not 5v x 9A. If you have 3A the maximum you can charge is 27w (9v x 3A) but if your charger is 5v then only 15w (5v x 3A).

Exynos very fast charging battery and I tested 8 hours on TV Pingu

Turn off adaptive battery. It will change the charging speed for battery life savings. It's a new feature but has been making people think fast charging modes aren't working.
