Charging Speeds

Hi,
Wanted your thoughts and opinions on charging speeds. I've never actually timed how long it takes to charge. i leave it overnight and it's ready when i wake up.
When i plug the phone into the charger, it flashes up slow charging for 2 seconds then disappears. which got me wondering how much it's actually using.
i used to use Current Widget app on my Samsung S3 which told me exactly how much current the phone was taking from the charger. typically it was 1A via AC/mains and 499mA from a PC. Plugged in to AC, I could play a power hungry game and it would still charge the phone at a good rate.
The LG kernel doesn't like these apps - the mA value is all over the place but it's typically <500mA displayed.
I could buy a USB ammeter to work out how much the USB charger is supplying but do you have any other methods of finding out? Do you know what your phone uses?
at home, i use a Xtrememac dual USB charger, 2x 2.1A output with a shielded 3M USB cable. for those wondering, it's the same regardless what cable i use. Have also tried with generic usb chargers, iPad chargers and official and OEM cables from LG and various other manufacturers. Have also used a data-shorted USB cable from PC which is the same result.
I haven't tried the LG charger yet (mainly as it's a 2 flat-pin plug and i don't know where i put the box) but i think i recall it being a 1.8A charger.

I use an application called "charger report" which can display current consumption and Xtar "USB detector" device. They both show the same numbers. But Xtar USB detector can detect voltage of a charger. The charging current of LG g pro 2 is 1.4-1.5A when the smartphone is not used and higher when I use it. Using USB detector I found out that this smartphone can charge with maximum current a charger can give only if the charger's voltage is 5.3v. So it chargers at full speed with original charger and two other chargers I have: a charger from my Lenovo s6000 (2A 5.4V) and from my Asus t100 (2A 5.3V).

i tried that app too and got the same results as with Current Widget.
i'll buy a "usb detector". thanks.

I forgot to mention that it take approximately two hours for charging indicator to reach 100% when the smartphone reports that it fully charged. And it's necessary to left it connected to a charger for ten to twenty minutes to be really fully charged. Otherwise charging indicator will soon drop to 90%. One can tell if a smartphone is still charging by touching a charger or by looking at current consumption: a charger would be warm and current would be higher than 200mA.

Is the GP2 Quick Charge (1 or 2) enabled? I can't read anything about it other than it's in Snapdragon chipsets. Not sure if it can be disabled or not.

The Snapdragon 800,801 and 805 is for Quick Charge 2.0
The Snapdragon 600 for 1.0

ok, does anyone use a Quick Charger with their GP2? is it noticeably faster?

not yet available in Austria, I have read it kills the battery life on

Hey ray-lee!
I just bought this phone and as it seems it could get someday similar problems as my former phone the Galaxy Note 2.
That phone has had problems with charger and cable also. I had to buy another set of charger and cable since the original ones gave up a few months after i purchased the phone (it was used). The cable managed only 500mA wich is very slow for a battery that strong. One night was once not enough to charge my phone from 30% to 100%. As it seems it is problematic to manufacture cables, that can hold up and continually grant the 1,8 A that would charge our device in just 2 hours. I read somewhere that the G Pro 2 is one of 5 devices that has blazing fast speeds on charging the battery. If you handle the cables with caution hopefully you will not encounter problems. If so my guess is, that you will have a hard time in finding a cable that can hold up. Sadly the stock cables are always more expensive. I do not get it, why companies dont build travel adapters that only charge ur phones built solid with sturdy cables to ensure the transmission of high currents. That way with charger + usb cable is just stupid, even when tis is an all in one solution.
I like this phone very much and i hope, that the cables will not be that sloppy as the cables that Samsung had/ still has. With Current Widget i get readings around 1500 mA (1,5 A) when connected to the stock charger. And yes the LG Charger is an 1,8 A one. I have also flat pins, but received an adapter to be able to connect it in Hugary.
Just sharing thoughts here, that will maybe helpful to someone...
:highfive:

i "think" as long as device has snapdragon it is Quick Charge enabled

I use the "Charging Report" app on my phone, and it reports proper values.
(Around 1500mAh with the LG charger, and around 1600mAh with the 2.0A Samsung charger.)
If your phone is charging slowly, check the CABLE. Cable can broke too.
(Many people complain about their Samsung charging cables, because they just stop delivering power after a while and just charge the device slowly.)

How long does it charge from 0-50 from50-100 from 0-100?

There aren't many chargers out there. and the ones that are, are usually US 2 pin. I need a UK 3 pin or travel charger (changeable pins) really.

[Q] Charging w/ alternate chargers... a risk?

I bought a brand-new Nexus 5 a few weeks ago. However it came with a 0.85A wall charger which is LG branded... and some 'generic' cable that was included too. Used it twice, but it took around 8-10 hours just to charge 80% of it. I plugged my old Galaxy Ace USB cable to the LG charger and it reduced to two and a half hours, same with my alternate charger from the aforementioned phone (5.0V + 0.7A).
But this led me to a question: Is using alternate chargers with < 1.2A of output a risky way to charge my Nexus 5 battery? I saw somewhere that it might even damage the circuit board (a rare case) and I'm a bit worried about it.

Using a charger with a lower amperage output will take longer for the phone to charge. Also, using a cheaper cable will also lengthen the charge time as the cable can pass the full amount of power to the phone. This has been my experience with using oem cables vs dolls store cables me chargers.

But... Will a Samsung wall charger with 0.7A of output damage my phone if I use it as my main charger? Because I also have a chinaphone which came with a bad charger and the Samsung one works fine.

No, the Samsung charger @ 0.7A will not damage the phone. I use a 1.0 A and 2.0 A Samsung charger with my N5 and it has been fine for months and months.

With the Samsung 0.7A charger, battery gets charged in 2:10 hours. I still don't understand it since I came from a low-end Samsung device which could complete its charge in about three hours (and that one had a 1500mAh battery...)

This is a tricky question, no doubt about it.
IMO, the cable quality is way more important than the current output (0.7 A, 0.85 A, etc).
I have a Samsung S4 charger with its cable (it seems very well built and it's thicker than other cables) and my N5 goes from 10% to fully charged in less than 3 hours.
Funny facts - happened to me:
- I had a very cheap cable (probably from China) that came with a battery bank. Surprisingly, it was the fastest way to charge my phone - reached almost 2.0 A. Later I found the trick: this cable doesn't have all the four wires, it only had two (positive and negative, without the data wires). I believe the data wires is used to perform some kind of amperage control; without it, no control was done and led to a very fast (probably dangerous) charging. I don't use this cable anymore, chances are that this nasty cable screwed up my notebook battery
- My N5 is almost two years old. Recently I had a problem with the Power button, the internal contact of the switch on the board was stuck 'pressed' and this led my phone to an endlessly force-reboot. I discovered this behavior after some google search and one of the possible causes of it is exactly the usage of a non-default / faster charger, it said that this could melt something - SOURCE
It makes sense, but I can't confirm this. I was able to fix this by smashing the phone on a table a few times (lol) and I'm still using a non-default charger
Can anyone confirm / say something about these facts?
For those who wants to see the diference between cables and chargers, give this app a try:
Play Store - Ampere
This app is a current meter, I use it on a regular basis and it is pretty reliable - the dev it's a XDA member and this app can be discussed here
Hope this helps!

You can not harm a phone with a 5 volt charger. The phone takes the amps it needs. More is better than less. I use 2 amp, 5 volt ones. As has been said the usb cable is the key thing. The better quality the better charge.

charging tests - whats the best charger?

Hey guys, as we all saw, the new note 20 charging specs isn't as good as the old one coming up to 25W rather than 45W.
But as for my past experience those on-paper specs aren't exact accurate and sure never fully explained.
unfortunately I don't own note 20 (yet?), so I can't share my highly detailed tests that I usually do, but those of you who own it and can share any data of test please write it down here.
Try to measure any of the following details:
* what charger(s) are you using? (Name / output powers / Power delivery version / etc... picture of the specs on it will be sufficient)
* what voltage and ampere (or watt) are being used (hold it few seconds to let it settle, it also should vary on the current starting point battery level, and wether screen is on/ off) (the more details you bring, the better)
* if you got no power meter than charging times could also be usefull (0->30, 0->50, 10->20, etc..)
after we get some tests here I'll sum it all up in a google sheets (like these: example1, example2, example3)
and after that we can get some recommendation of what 3rd party chargers are best to buy
If you are like me and like plugging a charger in every corner you probably want something good, with high speeds, and original is always more expensive than 3rd party ones so why not knowing the specs first.
Also we might find out that some charger can charge even faster than the original 25W one (what about 30W,45W,65W PD 3.0 chargers? what about PD 2.0? 1.0? etc..)
Your contribute will be highly appreciated!

I have an N9860 from Hong Kong. Normally I am happy to slow charge and have my charge settings set that way. Today, as an experiment for this discussion I enabled fast charging and super fast charging and connected to a 60W PD/QC4+ charger via a USB-C monitor.. The charger is branded Klearlook and was bought from Amazon in the UK a couple of years ago.
The phone is receiving/demanding only 15W at 9.2V, 1.6A. That is from 13% to 44%.
I removed the monitor in case it was interfering with handshaking protocols and it has had no impact on remaining time to full charge (now 58 minutes remaining at 46%.
Using the same charger I disconnected the PD cord and switched to an 18W USB-A port without a monitor. No change to remaining time to full charge.
So I'm getting fast charging, but not super fast charging from my combination charger - a charger that will happily run my Dell XPS 13 laptop from the PD port.
So then I unboxed the supplied charger and cord, previously unused. With the monitor attached I'm seeing 18W - 9V at 2A - and the phone says super fast charging, briefly, with the screen off and only the charging information displayed.
I'll just carry on as normal with my slow charging to 80% (thanks Accubattery) since that suits my needs perfectly well and should hopefully minimise battery degradation over time.

Thank you very much for that highly detailed measurement and review!
Results are pretty disappointing, your charger should have be good scenario
Hopefully (but doubt it) maybe others would find better results

The fact that maybe your PD QC4+ does not support PPS (the only way to enable 25W charging on Note 20 ultra or 45W on Note 10 plus).
Confirm that your charger does support PD with PPS protocol.
Yes, it's a bit annoying (to say the least) that note 20 is slower (downgrade) compared to Note 10 in terms of charging speed.
Regards.

I have no idea about PPS - never heard of it until now. The charger is no longer available from Amazon. I bought it in August 2018. Maybe it predates PPS. Anyway, a Google search found what appears to be the same product here....

Yeah, no mention of PPS anywhere, only AFC on the 3 non-USBC ports (limited to 18W).
And you are right Note 10 and S20 (the ones using PPS - 25/45W are 2019 phones), so the power supply being a 2018 product may lack the latest protocols.
I have a Note 9 (2018 product) and no ”Super fast charge“...
I had the same problem (bought a 45W car charger), just to find out it lacked PPS protocol, so no 25W or 45W charging speeds. I Had to return it, and carefully search for an updated version (more expensive) supporting it.

I have several chargers I use, but without any real testing, it feels like my 45w charger from Samsung is the best experience. I attached my charging log screen shots. 1%-100% in 1hr 13min. I get the super charging icon through the entire charge. I will try the same test with the 25w charger and see if there is any difference. It feels like it charges just as fast as my previous note 10+ 5g, which is why I got this charging block in the first place.

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.

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.

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.

Question PPS Charger

When i plug my P7P in to an Anker Nano III the P7P vibrates 4 times about 10 seconds apart before charging commences normally, is this how a PPS charger negotiates with the phone or is there a problem be it the charger or the phone?

Didn't even know what PPS was, but just did some reading on it. That explains my car charger. The delay happens no matter what I plug up, my iPad, wireless earphones cases, Pixel 4 XL, and now my 7 Pro. Seems like they're working as intended.
What is PPS Fast Charging, and What’s the Difference Between PD, QC, and PPS?

Never noticed this with my OnePlus 9 charger (that's also a PPS charger). I'll have to look out for it next time.

Well, even if the charger fails to negotiate the PPS charging protocol, it would be still charing at minimum speed, usually the standard 5 Volts at around 1-2 Amps (depending on the charger/phone).
It seems like it's being interrupted for some reason. Unless you have the same issue with other chargers, I'm pretty sure it's the charger you're trying to use (Maybe even the cable).

I've noticed that recently with newer chargers, some even explicitly mention it on their pages.
I don't know why newer ones are doing this compared to older PPS chargers, speculating either lower cost for a charge control chip that instead has to reset between negotiations or it's intentional to solve bugs with devices that might not negotiate right unless the connection is reset.

Cheers for the answers everyone, if it wasn't for the regular nature of the handshake (for want of a better description) and then charging as you'd expect I'd say the charger is wonky (Anker Nano III) simply because it is brand new.
I have ordered a new cable just to rule that out all my old cables as well.
I must have more charging bricks knocking about than a charging brick shop but from what i can gather only the Nano III is a PPS one

Hopefully it is OK now and the new cable seems to have sorted it out but i guess i will see more in the coming days.
The cable i got is an Anker 643 (just for future reference) I have always used Anker cables so i must have had an iffy one.

Hi, i noticed that my phone wasn't fast charging, despite i have an anker that reaches 18w. What kind of charger can i buy that allow my pixel to have fast charge?

Any charger which can handle at least 23w. Anything over that(per port) will be useless.
Also the biggest gripe of the Pixel 7 series is not having rapid charging.

Thank you for the reply! I had to buy a new charger because mine was not compatible I guess. The phone didn't show up the "fast charging" indication and it took 2.20 hrs to charge from 30% to 100%.

The Anker Nano 3 is 30W, PD 3.0 and PPS this is the UK version but all other regions version have folding pins which make it super compact.
