I have a note 20u 5g SM-N9860. While tinkering with charging options, I turned on Fast charging and disabled other options. However, when I connect stock charger and cable, it stays on CABLE CHARGING. When I turn on Super Fast Charging, it charges in Super Fast Charging mode.
Is anyone having this problem of not getting Fast Charging mode to work?
I think it depends on the charger. I don't think a super fast charger will just do fast charging. Super fast or just regular. At least that's been my experience.
Using my pixel chargers on the note it does just do fast charging, because that's all the charger is capable of.
There is an option to enable fast charging. There are two different options for fast charging and Super fast charging. Most probably that option is turned off. It is off by default.
I've experienced the same thing. You need to understand electrical currents and how the plug you putting your adaptor inside. To make it simple, use a charger that has usb a to usb c (old ones) for fast charging (samsung branded in my experience). This phone was designed to handle super fast charging anyway, why not use it?
None of the charge options make any sense to me on the N20U. Example , using an old samsung 18W brick charger. On slow charging it peaks to over 2000mA or over , on fast charging it peaks to around 2800mA. Using Accubattery to see value whilst charging. Using a 10W apple brick charger it charges are around 1000mA however.
This behavior was present across three different N20U devices.
Easiest way is to look at the charge indicator.
Around 1% a minute is snail charging.
Around 2% a minute is fast charging.

Is any difference charging my DHD form PC's USB then charging from original charger ?
I may be wrong, but I think wall charger provides more power than USB or car dock

I've read many times that using USB, you battery might last longer than using the wall charger. I've never noticed this...
USB seems a bit slower than the wall charger but other than that seems the same.
Install Battery Monitor Widget, and you will see how much current each option gives at different levels of charge.
To be exact, the device DRAWS current, it's not a question of the highest output being the best. If the device can't receive more juice, the additional output cannot be used.
When the battery is nearly empty you will see the biggest current draw - as the charge gets closer to 100%, the amount the device draws drops, until it reaches 0mAh on full charge.
My OEM wall charger provides up to 1000mAh, and the PC USB provides 500mAh, you will initially charge the device faster with the wall charger, until the current drawn by the device drops beneath 500mAh - after which point they will charge equally fast.
That, in the case of my phone (with a Mugen 1500mAh battery) happens around the 60% charge mark. So if the charger outputs are as mentioned above, you wouldn't see any difference in the rate of charging after 60%
HTC wall charger can output 1A with data pin short-circuit. PC USB can output 500~600ma or 1A on some laptop but no data pin short-circuit.
Fast charge mode is 900mA. It is on when data-pin short-circuit is detected OR on a fast-charge enabled ROM (or say, kernel).
Otherwise, it only pull 500ma.
Use your battery in your way. Charge it when you like. DHD can replace battery.
Stating the obvious BUT, of course, you can access your phones storage when connected to PC via USB for charging!

Also, be careful of using unpowered USB hubs - there may not be sufficient power on the port to charge effectively.
I think charger will have more power. :cyclops:
A wallcharger will always push more amps to the phone.
Don't get confused by people telling you, that wallcharging will damage your battery! That's just not true.
Every phone has an inbuild unit, that controls the amps going to the battery.
Charger outputs more power and therefore it charges faster. Some kernels have the option called "fast charge" which allow you phone to drain more power from the PC and allow it to charge almost as fast as via charger. You can not access files while connected to the PC if the "fast charge" option is enabled.
As already stated above, AC charging is generally faster.
Now many people say that charging by USB will make your phone last longer, but from my personal experience is quite opposite, plus, usb charging is easily interrupted (PC hibernating, stand-by, restarting, etc...). if you are comfortable with both ways (neither PC nor wall outlet too far away), use wall AC.
interesting, i noticed charging via AC (wall) gives my dying battery that extra oomph and seems to make my phone last longer in the day
I think Charger is always best than PC charging.
Its fast.
AC charging is faster due to a higher voltage and ma charge rate
USB uses a much more lower voltage and ma charge rate, it is true that USB charging is SLOWER and a myth is that USB charging does make your battery last longer.
On sense 2.1 I noticed my battery last 4 days with low - medium ussage because I only charged with USB but now I charge with AC with medium ussage my battery lasts a day.
With kernel tuner you can add a 4x4 widget which can tell you the voltage and mah raise / drain

I think the power if you charger the mobile from Charger it will be faster more than PC charging

+1. I vote AC charging
Charging with Original charger is awesome
Charging from Orginal charger takes less time then chargin from a pc usb
Charging from charger is faster, but charging from USB is more stable, as far as I know...Because it has a balanced voltage all the time. Not sure though. Just heard from somewhere.
So my friend borrowed me his charger from his phone, which is a galaxy edge. It said it was charging rapidly and omg it sure did. It was super fast. Does the N5 support any kind of fast charge? Will this break my battert?
Also attaching screenshot
Thx,
Dan
how many output amps was that charger?
I tried charger that came with Galaxy S6, which has output of 5V - 2A, and 9V - 1.7A when recognizes fast charging device. It charges my N5 from 15% to 100% in about one hour, but on lockscreen, it only says "Charging", and charges it really fast, without heating the phone, which then seems to be pretty much safe.
@tampitzel If the phone doesn't get hot to touch on the back while not used when charging (warm is ok), then it probably is safe to use.
If the screen starts to flicker, or doesn't respond well to touches (eg. while typing), that means that charger is giving too much voltage and that's bad for phone. But that mostly happens with cheap non-original chargers.
Cheers!

I will check, I didn't look to be honest, I was just baffled by fast charging
Nexus 5's OEM Charger (by LG) is rated at 1 amp - whereas the Blackberry OEM travel charger (folding plugs) is rated at 1.8 amp - been using it for a year - and, it fast charge the battery typically in 1 to 2 hours (even when it's down to 25% to 40% on heavy use for the day) with its extra long micro-usb cable. http://www.amazon.com/BlackBerry-Pr...1449956341&sr=8-6&keywords=blackberry+charger
No need for custom rom or other "tweaks" - for in-car use, a 2-amp mobile charger with a high quality micro-usb cable is the "key".
Good and beefy cable makes an improvement more than you would ever imagine!
The stock charger is rated for 1.2A not 1A.
The Nexus 5 doesn't have any kind of official fast charging. However it will allow up to a 1.8A charge rate. Plug in a 2.4A charger it won't go any higher than 1.8A. Its what the TI power circuitry is rated for.
I find it a bit strange that through coincidence that the Blackberry folding blade charger is the best (I would say perfect) charger for the N5. It was cheap and plentiful as well as high quality.
XZ's battery charge time is 2.5 hour from 25%, is it normal?
I turned on battery care mode.
Battery care is turned on?
Mine also came with a slow charger. When I plug it to my portable battery, it can still be pretty fast (and hot...)
With stock UCH 12 charger it takes my phone about 1,5h to get fully charge. 30min to 60% and 1h for the rest. It seems like Sony disabled any type of QuickCharge above 60% to prevent battery damage and it doesnt matter what type of charger you would use alter that - it will stick to 1000mA all the time.
Two things:
1) are you using QuickCharge charger?
2) do you or any of your apps use phone while charging?
Any of those would prolong charging time.

Please see my answer are listed below and thanks
1) are you using QuickCharge charger?
Yep.
The charger is UCH12.
2) do you or any of your apps use phone while charging?
No.
I turned off the phone during charging.

Try to keep it turned on then. I guess Sony could set offline charging to minimal settings and control QuickCharge with software. Try "Ampere" app to check how many ampers are you getting while charging (download from play store, no root required). It should oscillate from 700mA to 2500mA. If not (e.g. stuck at 1000mA) it means your charger could be defective and should be exchange for new one.
man. I got 75% in an hour while the phone was off :/ using the same charger as yours so there must be a problem, try to change the cable
Guys does anyone know if the USB type-C cable which comes with the non-fast charger is 3.0 Quick Charge compatible?? I've ordered a Anker 3.0 Quick Charge charger just wanted to make sure the cable is.
My case is even worse, tales 3 hours to charge from 13% to 97%
I am even using the newest Sony 3A usb c to c quick charger!
What the hell..
XZ support QC 3.0 so it should be able to charge from 0%(theoretically) up to 100% 1h40-1h50 using a QC 3.0.
During my few weeks i've had this phone (recived with UCH20 charger) i tried to test phone's ability to charge quickly and failed it took usually 2-2h20 min with original charger. I've ordered chinese charger (sony's UCH12W is 4 times more expensive, even samsungs and htc chargers are much more cheaper).
During tests (using ampre) i tried to start charging when battery dropped to 10%. I used 2 charges original UCH20,Tronsmart WC1T and 3 USB-C cables 1x original, 1x unknown chinese, 1x tronsmart(original included with a charger).
Conclusion:
UCH20 is slower, Ampere won't show more than 1560mA 10-60/70% then something around 1100mA and 780 or less 90-100%
WC1T is faster, 10-60% 2220mA (or less depends on throttling/temperature) then about 1500mA to 90% and less than 1000mA (usually 500-800mA) 90-100%
Tested with onvo adaptive charging on, stamina off, wifi on, brightness auto (0-40%), there was no difference betwen cables only unknown chinese cable was slightly slower but that is only my opinion. Battery temperature oscylated between 26-37/38°C(Ampere)
This phone will only fast charge up to 60/70% then it slows down a bit and last 10% is slow, it should preserve battery health yet still allow you to charge it quickly when in a hurry so u can use it for another few hours until you'll get back home and plug it for a night.

Good post, thanks for sharing,
I ve recently brought Anker PowerPort+1 charger QC3.0 compatible and used stock Sony cable and max output I got was 2180mA max using Ampere too.. What my question is now what should the XZ be drawing max? near 3000mA?? Battery care Off.
Ive ordered PortaPow 20AWG cable it states its also QC3.0 compatible so lets see how much it get and if it makes any difference to the charge times.
I will post my results in the next 2 days.
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.
Settings - Device maintenance - Battery - overflow menu - Advanced settings

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
To power up, you consume Red Bull. But your phone just needs its adaptive fast charger. Rate this thread to express how quickly the Samsung Galaxy S10e can charge. A higher rating indicates that it charges extremely fast.
Then, drop a comment if you have anything to add!
Ive been having a bad time charging my S10e. It only fast charges with the original wall charger. I have like 3 fast chargers:
Huawei charger (9V2A/5V2A)
Huawei Power bank Quick Charge 3.0
Laptop Type C port 15W
All the options charged my previous Galaxy Note 8 without a problem
But with the S10e i have many issues:
Huawei charger (9V2A/5V2A): Phone says Fast charging but estimates 4hr to finish (how is that Fast Charge?)
Huawei Power bank Quick Charge 3.0 : The same, it says fast charge with a very high estimated time, but here, the power bank uses a green led to tell the device is pulling fast charge, and it doesnt turn on while charging the S10e (but the phone does say fast charging)
Laptop Type C port 15W: Phone doesnt say fast charging, but phone charges about 1.3% per minute
its very inconsistent
Thats strange, mine fast charges with 4 different chargers, and car charger, all of them are QC 3.0, Sony, Blitzwolf, and some cheap ones from aliexpress.

Funny, I just posted in S10 thread about cpux app and now I see that it could help you with testing your charging stuff as well. Sometimes the cables are problematic too, so using that app, while charging, you can determine the exact charging currents. It's post #9 here:
https://forum.xda-developers.com/galaxy-s10/help/wireless-charging-t3926324
I have a weird behaviour too. With Officiel Huawei charger and cable, it's not fast charging. But it's only a little slower than officiel Samsung charger : 1h40 instead of 1h25 to charge from 15%.
Another weird behaviour is : when I put the 5A Huawei cable on my QC3.0 charger, it's not fast charging. But with the official Samsung cable, on the same QC3.0 charger, it's fast charging.
Huawei have its own system fast charging different from snapdragon or exynos socs..
