Charging thoughts. - Samsung Galaxy S7 Questions and Answers

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.

This one is good : [Qualcomm Certified] Tronsmart® Quick Charge 2.0 18W USB Car Charger
Opt among 1 output, 2 output or 3 output. However, please note that only 1 output port supports Qualcomm Quick Charge 2.0. Rest 2 are fast, however, not QC 2.0 Fast.:good:
what is it i need one ?
Check slickdeals. I've been using the $5 one (on sale). It outputs 12v so it charges the phone very fast.

Thanks for that. slick deals is having a promo on this.
However i was wondering s6 edge plus is not qualcomm based, instead exynos.
I was considering this one.
http://www.amazon.com/Aukey-Charger-Adapter-Smallest-Powerful/dp/B00M6QODH2
This is 2.1amp, and is the smallest, it can virtually snap right into your car charger port, without the protruding charger popping out.

Technology is same. High Volt, low Ampere. Any QualComm Certified QUick Charger would be compatible with Samsung's Adaptive Fast Charging. Atleast any branded ones, never go for any unheard brands. Usually Tronsmart, Aukey and Anker are good choices in average budget. Here's a video review I did for Tronsmart Adapter (Quick Charge) with my Edge+ :- https://www.youtube.com/watch?v=DR8W9ozZgAs
Also, please note that I have no affiliation with any of these brands, I just received a product for the review from Tronsmart and I found it really good. And I'm sure Aukey and Anker are equally good.:fingers-crossed:
Also, the Car Charger you are considering isn't fast charging compatible. Although it will not take much time with high Amp output (as specified), but its definitely not a fast charger.
Well, I am using CHOETECH’s Dual USB Car Charger with a dedicated port certified by QUALCOMM’s quick charge 2.0 technology so that I can charge my S6 Edge plus at quick charging rate even on the go. The main specialty of this charger is that it is not only charge the fast charging devices but also Apple devices like iPad Air 2 or iPhone 6 plus at much fast rate as compared to their original charger. You can consider to buy this from Amazon: http://www.amazon.com/dp/B00YX7Y3G8/

Thats very good info. Charging technology is evolving with the phones, and thats a very positive start.
The day is not very far when we might have multi thousand mah of battery juice and charging becomes a weekend job.
Do you mind taking notes while charghing 20% of battery with both the qualcomm fast charge, and the regular 2.1amp charger.
I've already placed an order for the Aukey 4.8A / 24W Dual USB Car Charger mainly because of the size. I'd really want a charger that can **** plush within the car's charging port.

Charging isn't a very quantitative process. First 20% of charging would never be same as next 20% of charging. Usually with fast charger, the first 20% would be amazingly fast while the regular 2.1 amp might take upto 1.5 - 2 times the time. Also, assuming two different devices have same sized battery, with the same charger, one might get 70% charged within 30 min while the other can get 80% charged. However, by the end of 100%, both might take similar time. Thats why, the % readings aren't very consistent or dependable. Its approximation. With 2.1 Amp charger, you won't loose much time, trust me. Also, I don't have the facts, but I have noticed that when I do the fast charging, battery drains out marginally quicker than when I charge through regular 2 Amp charger. Hope that helps.. :fingers-crossed:

Thanks that was good info. I've received my 2.1Amp Aukey charger.
I tried it yst evening while commuting back home from work, which is about 20min drive, and the phone was at at 50%, and it was able to charge about 30% in less than 30 mins. Looks promising. I love the form factor. you cannot evne see the charger plugged into the car port. Best of all, the car port's cover covers the entire charger when not charging, this way i dont even have to remove the charger jack every time i have to charge the car, just pluck out the wires, and snap the cover back to conseal the charger.

With constant gaming and videos watching (after working hours ofcs ), mine doesn't stay beyond a day. I'm very happy with that though. I have seen significant different in battery life when I keep the power saving mode on and it doesn't really impacts my gaming at all even though it says that power saving switches to the 1.5 ghz cores and stays that way...!
It doesn’t matter a lot but yeah the main thing is internal circuit and the premium component used in the manufacturing. All of the chargers integrated with Qualcomm Quick Charge 2.0 chip inside. But the best components used in the manufacturing plays a vital role. I can trust CHOETECH more in this area as they are offering 18 months warranty, which means they are confident about what they produce or deliver to their consumers.

Fast Charging?!?

Hello.
Can someone explain me how on earth does fart charging works on this device?
I've tried the included cable and charger, third party chargers and i don't see any fast charging going on?!? or any indication on screen that it's happening.
I've read somewhere that you need a special cable to use with the included charger (?!?!) is this true? where do you get this cable?
Phone is amazing but the charging part is really is really weird if you ask me.
Thanks.

do you get any message saying fast charging?
it doesnt show any fast charging message, so i wouldnt rely on such a message to make sure its working. just use the included cable and charger and ull be fine it takes about 2.5 hours to charge from 0-100% via fastcharge

Yeah ...That's why I asked. I plugged a meter to the charger and never saw it go more than 5v 2a.
I think it needs a special cable for the 9v but I can't find any info.
2.5h is not fast charge. My old s6 edge plus used to take around 70-80 m from 5-100% if if you put the remaining 1000mah shouldn't take that long lol
Mean in 30 min 40% recharge . My phone 0 -100% charged in 2:00
trust me, it is fast charge
calculate for yourself: original huawei charger is rated at 9V 2A, thats 18W total. 2A is 2000 mA. mate 8 battery is 4000 mAh.
best case scenario: 4000 mAh / 2000 mA = 2h
now add to that the extra time it needs to charge from 85-100%, because at 85% it automatically slows down charging to prolong the health of the battery and youre at the 2.5h FAST CHARGING time
also, i dont believe for a SECOND that the S6 edge+ charged that fast in your case. check this review: http://www.trustedreviews.com/samsung-galaxy-s6-edge-plus-review-battery-life-and-verdict-page-6
"Fast charging comes as standard with the S6 Edge+ and it works. It charged from 0 to 100% in just 1 hour 45 minutes. Samsung claims wireless charging has also been improved – it’s 27% faster on the Edge+ compared to the normal S6 and S6 Edge."
so thats 105 minutes for 3000 mAh. add to that 33.3% to get to 4000 mAh and u get a total charging time of..... 140 minutes. which is 2 hours and 20 minutes

I will make a full test from 0 to 100. I only charged from 40 to 100 and it took way more than 2 hours... that's why i asked if any special cable was needed. And as i told i mesured the charging rate coming out of the charger and never passed the 5V.
As for non Believing. It's REALLY pisses me off when people write that crap. Why would I lie? what would i gain from it? I sold the phone because i wasn't happy with it.... On the contrary and in case you don't know most sites like the ones you post are PAID to give positive reviews.
I checked with including charger and cable and the app Ampére and it charged with 2800mah. So, in ideaal situation it means a charging time of a proximity 1h and 26min. That means "fast charging". At least in my opinion. ?

that doesnt make sense what ure saying because in this case the site actually stated a HIGHER amount of minutes that it would take the s6 edge plus to fully charge from 0-100% so what now, theyre getting paid to write negative reviews as well?
also, no, ure not "gaining" anything from that, but people tend to exaggerate a lot, do a quick "drive by" in a thread and post random statements based on non-correctly remembered experiences and this is exactly how false statements are converted into "truths / facts". read my post and tell me where exactly i listed anything wrong. check various reviews on the mate 8, they all stare the same thing: about 2.5h for a full charge, give or take 10-20 min. it also compares perfectly with the charging time of the s6 edge+ in terms of mAh/min, and in fact these two phones are indeed VERY close, mate 8 being at 49mAh/min and the s6 series at around 50-52, so just marginally faster... which, again, is also represented by the numbers i listed in my post before
and again: there is NO extra message or notification stating ure in fast charge mode on the mate 8, it just does its job, thats it!
if ure getting slower charging rates / voltages, make sure to use the original charger and original cable and both with a proper high voltage power outlet.

I noticed the fast charging only really kicks in if you leave your phone alone. But if you keep using it while it's charging, it just charges at regular speed. But the moment I put the phone down and screen of for 5 minutes, it quick charges like crazy

I hadn't tested this. After i turn off my phone, a few minutes later it jumps to 9V 2A on my meter. If you turn it back on it goes down to 5V 1A. Must be a phone security thing, which is kinda cool in a way if you ask me.
Btw Apparently quick charge works with non original chargers too. I have a Cheotech 60W 6 port usb with 2 Quick charge ports (which supports 9V 2A/ 12V 1.5A) and it works Using the original cable though.
Don't use fast charging unless you really need it.
Always fast charging overnite (when you're not actually using the phone for many hours) can only shorten your battery longevity more quickly then with normal charging.

When I'm going to recharge for many hours overnite I use a 1A travel charger.
i guess thats the best way to restrict charging amperage although it shouldnt hurt the battery so much, considering that the amperage drops off sharply once level reaches 85% and above...
Sent from my Huawei Mate 8 NXT-AL10 using Tapatalk
Charging a phone with a lower rated current, will cause the charger to "try and match" the current requested.
Amps work in that manner, the device determines the draw. For example, using a 5v 5a (theoretical device) on a 5v 1a device will likely melt your adapter / screw up your phone from improper voltages.
In that case, an adapter may heat up, or if its smart enough (unlikely), it will turn off periodically. Most of the time, it will have an unstable voltage (undervolting) which is how some phones are able to detect an improper charger is used. This is bad for your battery.
I do not recommend charging with a charger that isn't rated for it. This is widely documented.

Any chance to reach charging beyond 1500mAH consistently?

Good day. I have a g930L. I'm using an old original galaxy s4 charger with a 2A output. I've tried monitoring the current with ampere pro and noticed that charging goes up to 1700mah but for only a very short time like a couple of seconds and reduce down to 1A. It stays for 1000A until it fully charges. I used also ipad charger 10W and still same behavior. I also tried different cables but only a maximum ofless than 1800. Buying a wireless fast charging will make the phone reach 2A?

You can use my app to monitor charging more easily
https://forum.xda-developers.com/android/apps-games/charge-monitor-t3555496?nocache=1&styleid=22
To answer your question, wireless charging produces a bit more heat so I don't think it'll charge more rapidly. If you want to charge faster make sure fast changing is on.

How about buying an official S7 charger?
Doesn't sound like rocket science that old S4 chargers and chargers designed for completely different devices are not charging the S7 the way it was intended

Question How do you get 25W charging?

I tried using two approved chargers. The Anker Nano II and official samsung 25W charger. Getting capped at 15W. Am I doing something wrong?

Same here, I don't think it'll ever go to 25W. One of those Samsung unfulfilled wishes? Am using the original 25W charger and DevCheck Pro readout shows oscillating wattage between 18.8-17.3(battery level ~35%) Maybe they could fix it w/OTA software?

I use this charger and the screen-on charging value goes up to 4 Amps (as reported by Accubattery) so I guess this is the perfect charger for 25W charging. Also in the specifications, the rating is mentioned; some are very near to 25W.
If you want to figure out the wattage use the simple formula W=V*I where W=wattage in watts, V=voltage in volts and I=current in amps.

Been using the very same EP-TA800 adapter, "25W" as Samsung misinterprets it because it only goes to 18W max or so: (started at 26%, second pic 45min later)
You are right, I can confirm also that the 25 watt charging is just gimmick.
When your phone are low battery (under 30%) you only get 25 watt of power pulled from your charger for a minute or so.
Then the continue charging speed are about 18 watt.
With AccuBattery pro app, after several various charging time, I get average of charging speed = 90% per hour
Usually I charge my battery from 20% to 85% in 44 minutes. With phone screen off about 30mins.
You can also check what charging levels you are supporting by going to Settings -> Battery and device care -> Battery -> More battery settings
Just a heads up for anyone not coming from the Z Flip 3, though, that Samsung reset the evolution of USB-C on the series. The Z Flip 3 launched with 3.1 and 15W, while most other phones were 3.2 and 45W charging.
If you follow Samsung's upgrades, you may already know that the difference in capacity between the Z Flip 3 and Z Flip 4 is 400mAh. Ironically, the difference between the S9 (15W) and S10 5G (25W) when 25W released was also 400mAh.
Samsung's linear progress aside, the charging difference is only noticeable in the first hour. You can read more about it at https://www.sammobile.com/2019/05/02/how-fast-is-samsung-25w-super-fast-charging where they compared the standards in depth.

Question Do the wall wart and cable matter?

I have some Anker brand USB-A to USB-C charging cables and just the wall wart (is there a technical name for those things?) from something... probably one of my old Samsung phones... it says "Adaptive fast charging" and output says "9.0 V === 1.67A or 5.0 V === 2.0 A".
( know that stands for "volts" and "amps", but I don't understand what the rest of it means... 2 Amps is "faster" than 1.67 Amps... I think... but what makes it charge at one speed or the other?)
My real questions:
1) Will using the USB-A to USB-A cable that came WITH the Galaxy S22 Ultra make a difference in charging speed?
2) Do I need to get a different "wall wart"? If I want one that supports USB-C plugging into it, I do, but will it gain me anything?
Thanks.
Edit: I guess tehnically it's an "AC Adapter" or a "power supply brick"...?
See how what you have now performs. The best/fully compatible would be Samsung own charger. And any decent quality cables
I use my original charger from my Samsung Galaxy Note 4 on my S22 ultra. It charges it about 90 minutes. I suspect this is the same charger as yours.
1.67amps x 9v is 15.03watts.
5.00apms x 5v is 10.00watts.
15 Watts is a nice steady rate to be charging your battery at.
45w...is really too fast if you want your battery to last more than 2 years.

I use my original charger from my Samsung Galaxy Note 4 on my S22 ultra. It charges it about 90 minutes. I suspect this is the same charger as yours.
1.67amps x 9v is 15.03watts.

45W is nothing and won't really degrade your battery much. Also, keep in mind, that batteries degrade regardless if you use them or not, they have a shelf life. So, in 2-3 years you will mostly need to replace your battery anyway if you plan to keep your phone for that long (assuming that you want the battery to be at it's "full" capacity after 2-3 years).

Even still...I'll keep slow charging my phone...knowing that it will last 5 years.
My note 4 battery outlasted the actual phone. The touch screen packed up first. The battery still lasted 6 hours screen on.
I replaced it with a Note 9. Again...the battery was fine...and original. Same story...6 hours of screen on time.
Now I have a Note 22....or S22 Ultra.
I have used the Note 4's charger for all of these phones...with my 10watt Kosee wireless charger. Even on the Note 4...with a wireless adapter.

It's still 10 Amperes into the battery.
I'm often running ~10 Amperes into my dual 224 Ampere-hour 6 Volt "golf cart" batteries.
They also weigh about 130 pounds more than your battery!

It doesn't push 10 Amperes into the battery.
PPS charging is pushing from 3.3V to 20 Volts at 2.25Amps, it's dynamic charging and it depends on the device's state (temperature of the battery, the charger, the capacity of the battery).
I'm not sure where you get this information, and not trying to be rude now but maybe you should check up on both PD and PPS charging protocols that Samsung uses before assuming it's charging at 10 amps.

I have some Anker brand USB-A to USB-C charging cables and just the wall wart (is there a technical name for those things?) from something... probably one of my old Samsung phones... it says "Adaptive fast charging" and output says "9.0 V === 1.67A or 5.0 V === 2.0 A".
( know that stands for "volts" and "amps", but I don't understand what the rest of it means... 2 Amps is "faster" than 1.67 Amps... I think... but what makes it charge at one speed or the other?)
My real questions:
1) Will using the USB-A to USB-A cable that came WITH the Galaxy S22 Ultra make a difference in charging speed?
2) Do I need to get a different "wall wart"? If I want one that supports USB-C plugging into it, I do, but will it gain me anything?
Thanks.
Edit: I guess tehnically it's an "AC Adapter" or a "power supply brick"...?

1. With Galaxy S22 there is an USB-C to USB-C cable not USB-A (maybe a typo on your side). That cable is rated for the full power charge the device supports, that is 45w. It can make a difference if you are using it with a proper charger (that's the actual naming for the "wall wart"...it is called "charger" or "wall charger" btw).
2. Yes, you should get a different one if you wanna charge faster. Your actual charger is a (so called) "fast" charger with the charging power varying from 15W to 10W. Your phone supports from 25W up to 45W, that are the "ultra fast" chargers.
I'd suggest to get at least a 25W charger, also there are some extremely good Anker alternatives (even better that original Samsung chargers), look for Nano II 635 or 615 Anker chargers.
If you wanna keep your phone for an extended period (like 4-5 years or more), you might wanna activate that battery protection charge that only charges it till 85% and will preserve it for a longer period. If you switch phones after 2, even 3 years, don't bother, charge it as you like fast or slow till 100%

If the charger is rated at 45 Watts and sometimes actually delivers that:
45 Watts / (maximum) 4.3 Volt battery > 10 Amperes
Maybe they are PWM-ing it or whatever, but the peak current is > 10 Amperes.
Ok, we can subtract the efficiency of the buck converter, but it's still in that neighborhood.
What would happen if I bought and used a 65-watt charger? Would it automatically drop down to 45 watts to charge my S22 Ultra? Could it damage it, etc.?

1.Q. Yes.
2.Q. It not gonna damage it if not pushed to full 100% or discharged completely before connecting.
Sorry to hijack this thread, but is there a decent wireless charger, that will give me fast wireless charging with a Spigen powerarc arcstation pro 65w charger? I have tried about 3-4 cheap crap ones, and they all give reg wireless charging of about 22% for an hour's charge.
The S22U‘s maximum wireless charging rate is only 15 watts. I use the Spigen PowerArc ArcField 15 watt wireless charger, which is powered by a conventional charger via USB C cable and works very well charging my S22U.
