I have fast charging enabled. I forgot to charge my phone last night and put it on the adaptive fast charger this morning at 0809. It was at 3% when it started. It's 0958, and it's at 22%. The phone has been power on during this time, but it should be faster than this. The setting for fast charging is checked.
Is there an indicator letting you know fast charging is engaged? I thought he gave a notification when fast charging is on. I know it worked once, and I saw one.
That strange
It only take 30 mins to charge 50 percent
Make sure you turn off all service and turn on power saving or shut down your phone
When I plug my note 4 in to charge a notification shows saying fast charge mode enabled (or something along those lines)
And it appears to charge really quick, I can't be exact on time, but my fine was down to 15% last night before I put it on charge, must have been about 15 mins and it was about 35%
Once I think it charged 20% to full in about 50 mins

That's what I thought. I thought I was imagining things when it didn't appear or maybe it only appears upon first use. I even thought maybe using Nova was some how suppressing the message.
Given you response, I thought maybe there is something wrong with the power in the computer room, so I took it to the kitchen. Then, the status message showed saying fast charging is on. Weird. So, I went back to the computer room and plugged it in. Now the message is starting to appear.
I guess the adapter glitched and was stuck in lower power mode. Not sure. Any way. Thanks for confirming the status message. It seems to be working now.
While my charger seems to work fine. I have noticed it wont pull more than 1000 ma at any given time. I was under the impression that when my battery is below 50% i should see fast charging at a rate over 1000 ma? I get 1000 ma off any decent tablet type charger, including over 50%. Yes fast charging is enabled and detected when the phone is connected to the fast charger.
Anyone else seeing this? Using "Galaxy Charging Rate lite" from the app store. Is there a better app that you guys like?
UPDATE: on a 2A 5v charger I will pull down average 1800ma when the screen is off, then it drops down as the screen is off. So, more testing is needed on the fast charger, I think I need a application that will log the ma draw at intervals to see what it pulls during "fast charge mode" with battery < 50% on the samsung charger.
Fast charging mode only works with screen off!
Charging at 9 Volt and around 1000ma
With screen on the fast charging mode goes off an charging goes to normal mode at 5 Volt and up to 1800ma.

I'm sure I read somewhere on XDA it also only works from 0 - 50%.
Going from my own experience, when I plug it in, I definitely see the "fast charging enabled" message appear in my notification bar.
However it's anything but fast. Mine has never charged faster than average speed that I have noticed, but then I rarely dip below 50% if I can help it, so that might be why.
Last night I put it on charge at 1am (at 59%), came back at 01:48 and it was on %93. Is that good? You tell me. It doesn't seem it. Perhaps my expectations are too high.
One thing I was always curious about is would it matter if you use an extension lead as opposed to plugging it directly into the mains. Not sure how much voltage it is able to draw though an extersion lead, but as must of them are supposed to be up to 240 volts, I'm guessing that wouldn't make a difference.

Are you sure, I go from 5% to full in around 80 minutes with device on, is yours faster switched off?
On my Verizon Note 4 phone running Android 5.0.1, if I go to settings/battery, there is a setting for Fast Charging which you can enable if it is not already. Just below that, there is a status message that when the phone is plugged in will tell you what kind of charging you are doing. I just plugged it in with an Adaptive Charging unit and the status said "97% Adaptive Charging" indicating my phone was 97% charged and was charging using the adaptive (fast) charging. When I unplugged it and plugged it back in with a non-adaptive charger, the status changed to say "97% - Charging (AC)" indicating it was charging but not "fast" charging.

If your USB adapter is plugged into an AC outlet or a long AC extension cord that is plugged into the AC outlet it makes no difference. However if you were talking about a USB extension that plugs into the adapter and extend the length of the DC USB cord that will make a major difference.

I've noticed that when I leave the phone plugged in overnight it sometimes just seems to stop charging at a random point somewhere throughout the night and I'll wake up with a phone that is only at 80%, 65%, etc.. battery. It isn't fully charging and then just being drained again either, it just randomly stops charging. It will recognize that a charger is plugged in and even says that it is charging but the percentage indicator in the Settings pulldown doesn't move. This doesn't happen every night and it has never happened when I charge the phone during the day. I assume it only happens at night because I'm not at my desk using it. I can also assume that the device isn't taking 8 hours to go from 35% battery to 75%, it doesn't charge that slowly. Any ideas?

Yeah, I have been using the cable that came with it. I've tried two different ones. I will try to see if it happens when charged through wall outlet.
Sorry for double post. Couldn't figure out how to attach image to an edit.
I looked at my battery settings and this is what I noticed. It looks like my phone is charging all the way up during the evening and then draining but the charging isn't kicking back or something. The huge gap in screen on time was when I was sleeping and there was no use of the device but battery is steadily draining.

As stated in previous post, I have not. That is the plan when I get home.
I have tried it through the wall charger for the past few nights and it charged just fine. I also tried it through the same cable that my N7 and Gnex were charged with and it still happened. I also tried various USB ports. Any ideas?

Is it possible the computer is sleeping and no longer powering the USB ports?
I had exactly the same problem for one night.
But it can't be a problem with my Notebook because
my Galaxy S charged just fine.
Probably due to power saving options on your computer, be they USB power saving settings or sleep related. If you want to charge faster you should definitely use the wall charger, USB charging is painfully slow for me... if i am using the device, load can exceed the incoming current and the phone will still discharge. Moral of the story > USB charging = useless.

It really isn't a matter of slow charging. I'm charging it overnight so the speed at which it charges doesn't matter to me. As long as it is charged when I wake up. I've been using the same computer to charge my phones/tablets/cameras for two years and I've never had a problem. I'm not even using the device though, it is at night when I'm sleeping.
I have the same problem all of a sudden. Happened twice in the past week, never happened for months before. I never charge from a computer, always with the provided adapter and cable from the wall. A few hours into the night, before the phone is at 100% (varies from 70-90%), it just stops charging. Battery graph looks very similar to the one in this thread already posted.
I wonder which device switches the current off, the phone, or the wall adapter. I would have guessed the phone, and if that is correct swapping the wall adapter won't do anything.
Or you can use Fast Charge from Google Play and flash Franco Kernel.
Then you'll be able to switch from USB Charge to AC Charge by charging with your computer.
However, the battery will heat and you may consume its life, so do not do that too often, only when necessary if you expect using your phone very long times as i do, i just change phone every 5 years or more, depending of my needs.
Also, i noticed than USB Charging slowing down the charge at around 80%, but still charging, i read with Battery Monitor Widget, and i seen it will gives minus ampere.
I almost forgot, you may also calibrate your battery, the first time, charge it to 100%, then remove the file "batterystats.bin" from /data/system or wipe it threw Recovery, that will ensure you to use your battery to 100% next time.
Mine seems to stop charging at 100% and go back down also. Mine usually is between 95-100% when I wake up though. Is that just how this phone works to protect the battery? I've never noticed this in any other phone I've had.
Anyone else notice the phone randomly doesnt charge when plugging it into the computer?
The battery will say charging, the lock screen will say charging, but the battery screen will say not charging and the graph will show a green charging line but draining battery. Replugging the phone in fixes it. I havent had an issue with the wall charger.
Theres nothing wrong with the USB ports, it charged my other phone fine and it charges this phone when it works.
my N4 charges fast when I plug it to my laptop. I connect it to my USB 3.0 port..
PCs aren't designed to charge phones. It may work for a dumbphone with a 500 mAh battery, but it doesn't have the amperage to charge a smartphone efficiently. The charging adapter that comes with the phone is 1200 mA (milliamps), a computer USB port only provides 500 mA (on USB 2.0). On USB 3.0, it provides 900 mA, so it will charge faster, but not nearly as fast still as the 1.2 amp travel adapter.
On top of this, the phone is constantly using battery power while on, so it is very likely that when the screen is on and you are using the phone plugged into the computer, the phone is drawing power faster than the computer is charging it.

That is not what Im talking about. It says charging everywhere except the battery screen where it says not charging, that is obviously a bug. A computer can power a phone fine anyways, they are made to be powered by a USB port.

I had this problem today. The battery was dying fast (Average for this one) and I had popped it into my stereos USB, The battery didn't show the charging sign.
WTF? So I switched to the "Cigarette lighter port" and with a different cable plugged that in. No go. Held in the power button to simulate a battery pull, Still didnt work.
Turned it off, Went back to work and three hours later getting ready to drive home i plugged it in. The phone was getting warm, But the battery charging sign never popped up. I turned it on and the left side (By the sim card) was getting ultra-hot but betterbatterystats said the battery was only feeling at around 101degrees (Normal for this small sun). A minute later it was highly uncomfortable to hold (Just near the sim card area), I thought the battery was going to catch on fire like those youtube videos.
I power cycled once again, the battery charging sign popped up and I breathed a huge sigh of relief. Seconds later the phone ****ing flipped its wig, It kept making the charger plugged in sound and vibrate every half second. I about had a stroke, Thinking it's going critical. ONE MORE POWER CYCLE, Everything is normal.
My earlier experience seemed similar to yours OP, Let me know if your phone melts your hand off and goes all bi-polar like mine did.
I'm having the same problem. It has nothing to do with a computer not being powerful enough to charge it, especially when they aren't even being used such as overnight. It has charged every other smartphone that I've used. It will say that it is charging on the lockscreen and on the settings pulldown but it will just constantly drain battery. I will put it on the charger before bed and wake up 8 hours later and it says it is at 86% with a steady decline in battery. This only happens when connected to my iMac and not when plugged into a wall outlet.
I wouldn't think USB 3.0 improves the charging speed at all, since the protocol still uses USB 2.0
I just remove all the cables and replace them. It seems to solve it.
Same with the AC adapter. I noticed sometime it would say charging USB when I switched. I just unplug everything and plug it back in and it goes back to normal.
/shrug
I havent noticed it getting warm, it just doesnt charge even though it knows its plugged in and is supposed to be charging. It works after replugging it in.
It also seems to charge abnormally slowly.
I wonder if the issue with the phone not working right with Nokia chargers (constantly disconnects and reconnects) is related to this. It may not have anything to do with the Qi standard because the phone just doesnt charge right period.
I usually charge my phone using USB while in the office. At home, I'll use the supplied wall AC adapter.
I've noticed that even though I'm using the AC charger, the stock battery display will show Charging (USB), which is not the case. Power cycling the AC charger usually fixes it to show Charging (AC).
Have also noticed that in some instances when it's plugged into the AC charger, the charging status would switch between "charging" and "not charging". Very obvious in the notification battery icon, where I would see the lightning symbol appear and disappear, about every half second.
I think there's an issue with the AC charger, or maybe it's the charging circuit in the phone?
Anyone experienced something like this before?
Cheers

Sounds like a hardware issue. If you want to run the test yourself, you can try swapping the charger with another OEM Nexus 4 charger (don't try to get around this). But I'd contact Google about this if I were you.
Might be the stock charger if thats what your using i had the same prob and sometimes but battery would either stay on the same percent for a while or go down so chanhed the charger and its been working fine ever since i still use the stock box charger i just changed the cord

It is due to temperature I believe. I have observed this behavior closely for a long time, so I'm almost certain this is the cause. I've seen it on the Galaxy Nexus and the Nexus 7. I can't tell you offhand the exact temperature they stop charging at, but I can tell you it's most likely between 50°-60° Celsius. You've got to let your devices cool off. It may be a pain, but it protects your hardware, so when it stops charging, your phone is saying "Hey partner, you think you could let me cool down for just a second? Is that too much for you or what? What's your problem, you dingdong?"..
... Or something like that. If that's not exactly what it says, it's very close.

Same here. Worked out for me it was a dodgy cable. Using the supplied cable through a laptop, I will also from time to time get the plugged/unplugged notification on the computer, which being audible made me realize how often it was happening.
The supplied charger brick now seems to work flawlessly with a different cable (ie, always says AC, no odd charging/not charging behaviour, etc).
Try that and see how you go.
I guess it's the cable. I've tried using a generic ebay cable and it appears to be working fine now.
What sort of mA values are you getting when using the stock AC charger?
Battery Monitor widget says that the phone's only getting around 500mA when I believe it should be getting more than that. I've enabled the USB fastcharge in the options. and have left everything at default. This is after waking up the phone from standby. Keeping the screen on drops the charge rate to 200mA thereabouts.
No music playing, 3G and connected to a wifi access point.
Hi guys I'm not sure it's supposed to be like this... i turned on fast cable charging, then I put it on charge, and even if in the scroll down menu it says fast charging, if i go into the details of the battery the option "fast cable charging" is set to on but greyed out... but if i unplug the cable it turns on. It's just greyed while charging... is it supposed to be like this? Thanks.
When you plug the phone in to charge it will always grey out the option so you can't turn it on or off.
The only way to change the option is to unplug the phone and then set to whether you want to it charge fast or slowly.
Personally I always have fast charge off because it seems to me like the phone battery lasts longer.
Out of curiosity... from 5% how long does it usually take for you guys to charge to 100% with fast charging and slow one? thanks!
It normally takes myself about hour and half to two hours mattering on how much I use phone while fast charging.
Around 2 hours ish with non fast charge.
When my phone is charging it seems to randomly display charging rapidly, charging, or charging slowly. I'm running stock nougat and have tried the original charger and another PD charger with the same results. Is his a known issue or a phone problem?

It's possibly just how they charge.
Lithium ion batteries in phones don't generally charge at just one rate from 0-100%. Around 85-90% they slow down. And the last 5% or so may be the slowest.
That's probably what you see
Assuming you're seeing it switch to charging and then slow charging as it gets closer to 100% this sounds normal.
I thought that at first also, but it does it all the way through the charge.
Mine does this fairly often, and the battery percentage never matters. It happens equally as often at 40% as it does at 70% or anywhere in between. Additionally, mine will sometimes go onto the charger and just be stuck at "Charging slowly" and never change. Nothing's changed on the other end, either - it's plugged into the same port it's always plugged into. I seem to have better luck in getting it to charge rapidly when I plug it in with the display powered off, but that could be a bias I haven't eliminated. I have no actual statistical data to back it up.
I've opened a ticket with Essential Support, but haven't gotten a response beyond them asking a few questions and telling me they'd "look into it" (almost a month ago).
I will say that regardless of what the display actually says, the time it takes to charge fully seems to be fairly consistent (for the battery percentage it's at when I plug it in, obviously). But no, you aren't alone in seeing this behaviour. I'm on Oreo, too, not Nougat.
Mine does the same but still charge's from zero to 100 in expected time around 70/80 minutes,it tends to jump to slowly when nearly full .
Have to say battery life I'm getting is nothing short of astounding for a 3040mha battery
Sent from my PH-1 using XDA Labs
Thanks for the replies, I'll try timing it and seeing how long it takes.
same here with original wall plug and USB cable. Stock 7.1.1.
After reboot it stays on "Charging rapidly". until another day or so.
Oreo seems to fix it.
btw, seems that when I'm charging in Flight Mode it's always stuck at "Slowly Charging" , looking forward to test this on Oreo.

can anybody confirm that PH-1 is always stuck in Slowly Charging when in Flight Mode? (and if you are Android N or O). I'm wondering if it's my device or general issue.
btw here Essential support answer on that issue:
With the Essential phone the charging speed fluctuates and there are different factors that come in play, including the percentage of the battery at the time. It is to reduce the heat and to prolong the battery life of the device.
If your device is in airplane mode then all major processes including your cell network and GPS are off, therefore the drain on your battery is reduced that would otherwise need to be made up for by the quick charge.
The device should take about an hour an a half to fully charge, is it taking longer than that to fully charge?
