Question:
Does HTC One have a overcharging protection?
I am sure it does, right? What type of modern device would not have this feature or who in right mind would sell without this feature?
Other wise we would be hearing a lot of reports of HTC One shooting out smoke and flaming up while phone is plugged in charging during user are in bed sleeping?
Reason for me asking is because one of the HTC One user called up HTC to ask about this question and he said HTC told him that even when phone is at 100%, it is still continuing charging and that user must disconnect the charger. (makes absolutely no sense to me, htc made it so that we need to monitor every % of charge? for hours?)
Anyways,,, this person made sure that the HTC support agent knew what he was asking and that he had called again to speak to different agent and had received same answer.
I am in to electric radio control, so LiPo batteries and charging isn't anything new to me...
I still do not believe the answer this member have received from the support agent. But... if there really was a tiny chance that it is true... this would be a ticking time bomb.
What you say people? Just some totally misinformed htc support agentS ?

Support agents and customer service centers are just like any other group of people, most of them are idiots and the rest of them will mess with you if they feel you're an idiot. That even includes Indian call centers.
That person either misunderstood or was messed with, maybe they were so annoying/gullible that the rep just wanted to give them an answer that would scare them away. The HTC One can't overcharge unless you hook it up to the wrong power source. Jam your usb cable right into a wall socket and it'll probably pop into flames, but aside from that don't sweat it.

Nope, it has overcharge protection circuits built in. If you charge while the phone is on and leave it hooked up for a long time, it will say 100%, and the LED will be green. But once you disconnect from the power, it will rapidly go to whatever the true charge state is (96%, or whatever the phone has gotten down to). I'm sure that eventually it would resume charging, go back to 100%, then go down again, but I've not tried it. I power mine down at night, so that after the 100% is reached there is nothing to drain the power down.

I cannot agree more. Most of the call centers have dumb people except for a few. I am an Indian but now in the states and I used to work for a call center. I had technical knowledge far better then the others and in my team such calls would be routed to me or either I had to call them back. Sometime when they don't know they are also asked to give a vague answer.

Leaving the phone plugged in when fully charged
I spoke yesterday with someone at HTC's hardware & repair center, and he seemed to have a clue. When I asked him about this he said that Taiwan tells them the biggest thing making batteries go out prematurely is charging habits. The problem, he said, is leaving the phone on the charger all night.
He said that when the battery is full charging shuts off, but then the phone uses a bit of juice, which makes it no longer full, which makes the charging restart. So, if you leave the phone charging all night, it will be starting and stopping the charging all night, and he said that this trains the battery to hold less charge. His "HTC official" solution was that you should take the phone off the charger when it indicates full charge.
So I'm curious what people here think of this. Is this a potentially valid reason not to leave the phone charging overnight? Or, perhaps, charging with the phone powered off would prevent this (I should have asked him about that).
Oh, he also gave me an actual reason why I should use only an HTC branded charger instead of just any old charger from the Internet: he said that the HTC charger is a 5V 1A charger with a voltage regulator which allows it to push out only 3.7 volts. He said that chargers don't usually indicate the actual voltage that their regulators allow them to push, and that
- If you push too little it makes the low end of the battery bad
- If you push too much you'll burn the battery out too soon
He did admit that, if I were able to confirm that a 3rd party charger really was regulated to 3.7V, then it ought to be fine for my HTC One.
Thanks
Sadly, I don't think this one had a clue either mate... He knows enough to tell you "voltage" and stuff, but it actually works a bit differently:
When you put the phone to USB connector, the phone has no way of telling the circuitry inside your PC to drop the voltage to 3.7V (which in fact is another mistake as you can't charge 3.7V battery with 3.7V - you have to use at least 4.2V, but the voltage is dependent on the state battery is in at every moment of the charging process...)
That being said, you can rest assured that the wallplug charger has equal voltage - 5V DC (Amps are not important for charging - less mA means that the charge will take longer, but more mA doesn't mean the charge will be faster - the phone only takes what the internal charging circuitry can process and feed to the battery.)
And it does not push anything, it either has a potential (voltage) or doesn't, it can be dropped to lower than nominal, but that means driving the switching power supply beyond it's limit and that is bad for the charger...
Now for the overnight charging:
I charge my phone almost exclusively overnight and the battery is fine. What the guy told you tells me that he didn't actually know how these chargers work.
The phone has it's internal circuitry to regulate the voltage and current being fed to the battery, usually it is conrolled by a microprocessor, and once the 100% level is reached, it stops charging and feeds only maintaining current to the battery so it doesn't actually go below 100% level at all, not until you unplug it... This current is usually few mA + whatever the phone consumes at any given moment.
I hope I made your sleep a little easier
It will stops once it reaches 100%.

I'm assuming you mean charging overnight when the phone is left on. I charge mine while powered off.

It applies on both ON and OFF, the circuits are there, you can't not have them while the phone is off...
And if it really does stop when the phone reaches 100%, the engineer behind it would have to be an idiot
Try taking miliAmp meter (any mullimeter would do basically) and place it between pin 1 on the USB and the actual wire that leads to the phone - you will see a drain there once the phone reaches 100% - that is the maintain current to prevent the fluctuations around 100% charge...

This is probably a dumb question but, I was wondering if the phone gets charged to the fullest while using a usb extender plugged into the htc power outlet and then from that to the original htc usb cord? Also I read that it is ok to use an official motorola wall charger. Will the phone get charged to the fullest with that? Just trying to see how i can make my battery last longer at it usually only lasts from 10am-4pm and i have to use it again.
Mmmm...
Not really sure what you're asking here. If the charge indicator is showing on your device, however you've got it connected, it will charge until the battery is full. You can tell this by the LED 'circle' showing constantly.
I don't know about the Motorola charger. You'll have to check the output. You need DC 5v @ 1A. I would be surprised if there is a vast difference between devices. The voltage is the main issue. If the ampage rating is higher, the battery will still only draw what it needs.
Battery only lasting 10am - 4pm... you must be a heavy user! I occasionally can flatten mine in a day (6am - 8pm), but very rarely. Usually I can get two days out of it.
most i do on the phone is text. do you have a lot of apps installed on your phone?
Yeah...
I think I have a lot... though compared to some probably not! I have about 20 third-party apps on it. I don't do many calls, but I use the apps a lot during the day, especially RSS Hub, Opera, Word and Excel. Nothing major really.
You'll probably get better power management from a custom ROM, if you haven't got one installed already.
yeah roms scare me as you cant find a "hard spl" for the alltel version of my phone. or nobody really talkes about roms on the alltel touch pro
I think its common knowledge that the HTC One has a slow charging speed compared to other smartphones.
Thus, since i use my phone all day..on the move, leaving it to charge at a stationary spot is rather annoying, so therefore the only workaround is to charge it overnight and use it during the day. But the problem with this is that it'll be done charging far before the night is over, and stay plugged in, therefore my question is, (or rather two questions)
Does the phone automatically stop charging once it hits 100%? Or does it continue to keep the phone at 100%, reducing the battery life of the phone?
HTC should have included a faster charger. My One takes a few hours to fully charge and doesn't even really charge when I'm using it while charging.
As for your question, I don't have a actual answer but I imagine it maintains the 100% charge by constantly charging it.

A faster charger wouldn't make a difference as the amount of charge the phone can accept is determined by the phone itself. The phone requests X amount of power, and the charger provides it, as long as it is capable of outputting that X amount. A 2amp charger wouldn't charge the phone faster.
And yes the phone has an intelligent charging chip. It stops charging at 100%, and drip feeds the phone when it detects the battery level going down. On the HTC One X, they did it in a weird way.
The charger goes up to 100%, then lets the phone go down till 95% before starting to charge again. This confused a lot of people as they would unplug their phone at 100%, then 1 phone call/text message later it drops to 95%, showing the real battery level

This is exactly what i was looking for, thanks. So it does stop charging at 100%, allowing me to charge it overnight beyond the length of its charge cycle without reducing the battery life?
I understand that dropping down a bit and charging again is better than constantly keeping the battery at 100%, but isnt it technically...still bad for the battery in the long run?
For those that experience long first charges, the first-charge charging time MAY be intentional.
I couldn't figure out why USB-500mA was taking so long to charge my phone, and wondered if the charging circuit wasn't correctly detecting the current rating (500mA) of my computer's USB. Charging shouldn't have taken more than 5 hours.
It took 20.
I'm getting ~>6hr screen on time now/charge and USB-500mA charging is snappy-- 3-5 hours or so. (albiet turned off all syncs except contacts and a few apps, app quarantine on facebook/drive/etc, and calibrated Lux for indoor lighting at 13-15% up to 150 Lux or so; and 1% for 0 Lux (at night); and Faux123's 003b3 kernel clocked at 1.6ghz and EcoMode and Snake Charmer ON in FauxClock (faux kernel control app).
TL;DR: the charging circuit wants the first charge to be slow. Don't worry if it takes long. It won't always take this long. Just for the first charge.

firstly, the first time you go to plug in your phone to charge is not the first time it has been charged. it has been turned on and off multiple times during production. also, i don't know about you but my phone came charged 90%. how did that happen?
secondly, it's extremely improbable that extra circuitry was put in place to limit the charge rate just for the the first time charge. if for whatever reason they wanted to limit the first charge, it would be done in production with production equipment.
which brings me to my last point...what is the benefit of rate limiting the first charge cycle?
TL;DR
Phone normally charges at 1.2A, you feed it 0.5A it's going to take more than twice as long to charge.
Simples....

hmm good thoughts. My phone came at 45%, which is right in line with what you should store a Lithium cell at, hence the start of my theory. Presumably, the cells get partially charged at the factory or are simply made that way-- have to be, because they won't recharge if they drop below 2.9-3v or so, charge has to start somewhere. 90%, probably not made that way though.
I doubt they have a lineup of USB-micro chargers at a dust/lint-free factory doing the charging for us, which lends credence to the notion they are _installed_ charged/factory conditioned.
Factory testing, would probably only take 15 minutes on the phone, if they even test everything (probably just basic stuff).
extra circuitry-- nothing extra physically besides the charging chip, the charging circuit for lithiums requires ability to sense charge current, because that's how you know when to stop charging (i.e. all lithium chargers have to be intelligent). So then you simply have to have a single 3-state flash or eeprom byte that starts at FF (programmed from chip factory), is initialized once to 0 on powerup in the chip (not android or even firmware, lower) code iff it's FF, and then gets written to "1" after the charging circuit gets shut off.
first charge cycle-- because if I thought they were doing it, I could see why they would (chemically). I guess they're not, so maybe I can't anymore. In theory, I could see why it COULD be good, something along the lines of running the car hard the first 1500 miles to ensure the piston seals wear/bed properly to the cylinder.
Charging through USB to your computer is always slower though. It was not intended to make the first charge slower and your battery results are mostly a result of your customizations.

Just a warning to anyone reading this thread... ALL OF THE CHARGING INFORMATION IN THE OP IS COMPLETELY UNTRUE
It really makes no difference how you charge the phone, especially so for the first charge. The phone's systems will detect when the battery is at full capacity and stop charging as necessary. So nonsense like the OP makes absolutely no difference, as it simply stops charging once it reaches 100%. The reason your phone charged slow, is simply that USB provides (as has already been said), a much reduced current compared with the wall-socket chargers.

You are comparing mechanical and chemical things here. like comparing wind and wave. Both can push things but driving force is absolutely different.
hmm..
im getting 5.5-6 hours screen on time without charging it at all when i just got it. and its first charge took just under 3 hours.

nope, not completely untrue just mostly untrue.
I take most of it back though.
It's possible the ultra long charge was because I didn't have a SIM in, constantly running radio looking for service?
The engine burn in is an old wives tale as well. The engines are all tested at high rpm the same as transmission before final assembly. No need to drive hard when it is new unless you want your transmission to learn your aggressive shift patterns!

Not having a SIM in wouldn't cause that effect. It'll still be connected to a network, as it has to allow emergency calls, it simply won't be allowing you to make/receive any calls/data/texts. It was just a slow charge as it was over USB, rather than the full power chargers.

but nothing else explains a 20h charge. That's 10000mAh at 500mA/hr (USB). I checked the CPU state and it was 300mhz the whole time-- same as every night. Except now, it only takes 3-5hrs to charge (on the same 500mA usb slow charging)
maybe the battery did need conditioning... - .-

To be honest (and I don't mean to sound rude here, just explaining my thinking), I don't really believe that happened. It seems highly unlikely, and goes against pretty much everything about the way the batteries work. This is assumign the USB port was actually putting out the full 500 mA, and that the phone wasn't having any kind of extra drain at all (which wouldn't be that unusual on a new phone).
Even if for some strange reason the battery did take an exceptionally long first charge, it was just a random occurrence probably due to a minor error in your battery. That doesn't mean that all first charges will or need to take that long.

really? that's weird. why do they say the exact opposite in the service manual (stay under 4k RPMs for the first 5-10k miles) if they've already broken it in? I saw some pics on a site from a guy who had people send him their 200k mile pistons and compared between those given the hard drive from day 1 vs. the soft drive break in method per manuf. spec. Those that were driven hard on purpose for the first 500 miles or so still had immaculate piston seals and zero carbon blowby/leakage. Maybe he was cherry picking results but the theory sounded good-- why else would they cross bore the cylinder? Might as well drive hard to help the piston seal as well!
of you are using your device when plugged into the usb, many times itll drain more battery juice than will be brought in. there are even live wallpapers that you can have running while plugged into tbe usb, and watch the battery drain right before your eyes. plus each usb device thst you have it plugged into could charge the device differently, some barely let a trickle in.

well, I will say that I can swear it happened because I plugged it in at ~8pm and it wasn't done the next day till like 5pm or something.
Only remaining theory (this actually makes sense more I think about it), is perhaps got confused and thought I was on USB 100mA. I was using a semi flakey USB cable that sometimes seem to have trouble detecting my phone is attached in Windows. Maybe that's what it was.
Additionally, the next day my battery exhibited some very peculiar discharge curves. After using for >5m screen on and turning the screen off, the battery % would rise about 3-5%. Additionally, I think I managed about 7 hours screen on time after that charge lending credence to my theory that slower charge curves store more energy.
Hm. I think I will try this again.
My phones been dead for about a month, most hope was given up but heres my last ditch. I updated to android N preview. Used it like normal. The last day (before my phone ate ****) i was having problems charging it. It wasnt accepting the charge almost as if my "Quickcharge 2.0" had stopped. In fact it would discharge while connected to turbo charger. Anyways that day i went swimming, where i live its very hot i left it on the charger near the pool and it had gotten super hot. So i took it off and put it in a chair and it was on again super hot (hot enough that it burnt my hand when i touched the glass) and it was still on it hadnt shut off. Some people there put it in their cooler for me and that was that, although i noticed a burn mark on the actual usb port on the phone itself. Fast forward a few hours. I was skyping some chick got off skype. Turned my phone off in the hopes it would charge faster. ( it was at 13%) plugged it into the charger, Nothing. Tried to turn it on, Nothing. I finally got it to boot up ( i had to press the **** out of the power button) and the google logo came up. Then it turned off. Tried again to power it on. Same thing, google logo dead. Left it on the wall charger for an hour. tried to power it up, nothing. Used a samsung wireless charger on it for close to 3 hours. Tried to power it up. Still nothing. Power + Vol Down. Nope nada. Opened it up checked the wires everything was plugged in and secure. I didnt make it any further than the backplate because i stripped the screws. Since then its just sat on my shelf, but today i dropped it on my foot and i decieded to see if it would turn on, so i plugged it into my pc (and this is honestly the reason im writing this) and i wiggled the charger around and my pc actually "sensed" it. It said that "The usb device has malfunctioned" so idk what that means. Maybe its still there maybe not. Ik that if i can get my pc to recognize it again it will be difficult as that port on the phone is on its LAST leg.
Let me know what you guys think. Sorry for the short story. Just want to make sure you know everything as it happened
Also when i plug it into the wall, or use the Qi charger on it the device heats up/gets warm. Again dont know if its anything but the more the better.
Could be anything really, possibly a bad battery, if the QI charger isn't helping. How old is the device, and when did the usb burn mark appear?
Okay so I am going to give my best guess here, that the battery in your phone has gone bad, and it was killed by your charger going bad with an electrical short circuit.
Here is my reasons for think that...
Currently your phone won't accept a charge at all, so that leads me to believe that the battery has gone bad.
As for my suspicion that your charger went bad, I have had two different quality brand chargers (HTC and Samsung) go bad on me over the last 3 years or so.
Both times the charger failures caused the same symptoms on my phone that you described...the phone getting extremely hot, and the battery discharging, while connected to the charger, instead of charging.
Luckily for me, in both cases, my phone batteries did not completely croak.
In one case the battery did bulge out the phone, but it was an older HTC M7 and it kept working.
In the other case, I noticed that hot phone and the discharging, and immediately unplugged the charger and tossed it in the trash.
So that is just my two-cents.

What advices do you have to avoid this kind of problem?
Okay guys. I would have to check the IMEI to give you hard facts for the dates. Which I can do im just at work. But last I looked it was manufactured in, March of 2014 or close to that. Ik for a fact that he model was an XT1103 it was completely factory unlocked however my bootloader was locked. Storage was encrypted. And it was the 32gb version. Yes! It could quite possibly be my battery.
Before all this started I was having trouble getting it to charge and I was using a Samsung mini USB with it. But the outlets at the pool I don't think are designed to charge phones. Anyways the burn mark on my USB port showed up the same day. I just didn't notice it (I think) until later that day,but after I got it my phone no longer charged. It would either discharge off the charger, or discharge slower on it.

Sorry for the delay in replying...RF got in the way.
Anyways...I really can't offer much 'technical advice'. I can, however, offer some practical advice.
1. Use brand name chargers or be careful if you do use an off-brand charger.
2. If you are charging your phone (either on a brand name charger or an off-brand charger), and you either feel it getting hot or you see it discharging (or both) immediately unplug your phone and throw away the charger.
3. If you do notice that the battery on your phone is bulging, either replace the battery or if it is a sealed device, replace the phone.
Honestly, that is the only advice I can give.
So guys ive decided i m gonna go ahead and try and replace my battery since its rather inexpensive, im gonna order the parts from ifixit. such as anew midframe and battery. It should be done hopefully by next week. Im still completely open to opinions. When its complete ill make a post.

In my case, i use aukey quick charge 2.0 and it works great, when i charge the phone, i do it on the night and try to not use when it charge, i dont like to charge with scrap chargers, but thanks for the advice, i will take care on that :laugh:
Alright well today my screwdrivers (ordered from china) came i disassembled the phone, havent gotten my battery yet but theres some things i would like to note. The first being that the old battery had alot of corrosion along with its contact to to mobo. ill update when i get the new battery in.
Hi guys,
I normally charge my p20 pro every night. Plugging in an hour ago, I recognized that supercharge doesn't work. Sometimes charging completely stops.
Tried to reboot, nothing changes...
Installed battery app and see that maximum charging current is about 1700 mah.
Does anyone now what it could be?
Tried another charger, same situation. Tried different cable, same situation. P20 from my girlfriend on my charger and supercharge works fine.
Thx Benny

Must be a fault with your phone if thought tried another known good charger and it still doesn't work.
Another strange behavior is that sometimes charging stops. And sometimes usb options pop up like if you connect to a computer... But phone is on charger.

Sounds like hardware issue. Get a replacement.

Hi there, I've been dealing with the same issue as you for the past few days. Mine I can confirm has resolved automatically. Do you expose your device to water or moisture alot? I believe that the p20 has been optimized for safety incase the phone is ever dealt with moisture in the charging port. My issue was that the phone kept saying 'supplying power to connected USB device' when in reality, there was no device connected to the phone in the first place. This was on the night I had dipped the device in water, it appears the USB port is more susceptible to being affected by moisture than any other area of the device. I have taken note that while the charging port is wet, the phone does not enter supercharging. As for how I was able to resolve this issue, I first used a blower to clean any dust or debris in the charging port, this allowed the device to return to its normal state and not think that it is connected to another device. However, this still didn't allow supercharging to work, the following day i was desperate to get this fixed without taking it to the service center. And it would still only show 'charging' and not 'supercharging' whenever I connected the device to the charger (it would actually show super charging for a split second and then going back to charging). I finally decided to just clean the port with water instead (I know this might sound risky and stupid) and so I did it. When I tried plugging it in again it would not supercharge, but i already had anticipated this. Instead, I waited for the next couple of hours for the water to dry out and when it did, finally super charge was working once again. So my suggestion to you is:
1) Clean the charging port as well as you can, and have some patience (incase you do end up using water, as the phone does not super charge when it finds the port to be wet.) Also if you do end up using a pin or something similar make sure to gently wipe away the debris (if any) and be careful not to damage any of the connectors of the port.
2) disconnect the charging adapter and make sure it is plugged out for atleast 30 minutes before plugging the cable and adapter again.
3) if these don't help you then you should definitely go to the service centre.
EDIT: IF YOU DO USE WATER PLEASE MAKE SURE TO ONLY USE A SMALL AMOUNT AND NOT BATHE THE CHARGING PORT IN WATER!!
Thx psycho!
My phone got wet yesterday and the day before. Today morning supercharge works again. Yesterday evening the phone said normal charging but not plugged into wall. Only plugged the charger into phone.
That might be a symptom of a short circuit by water.
I got an app to measure the current ampere.
Does anyone know how much ampere the p20 takes from the charger?
I know that the charger goes down with the ampere when getting near 100%.
I will take a measurement in the afternoon again when supercharging.
How long should I take to get from 30 percent to 90 percent for example?
I hope it's not a hardware problem...
Thx guys.

You're welcome! I couldn't find any solutions online too so I get how you feel. I think it's just the way they programmed this phone, it won't super charge when it detects any kind of moisture underneath it, when that dries up it goes back to normal so it charges as it should. As for the max current you should expect it to be around 4800 mA - 4900 mA on lower battery levels. Expect this to decrease over time but that is normal, it's just how Huawei's super charging works to ensure that your battery lasts longer and is safe to use. So if it charges above 4000 mA when you first plug it in you should be good. You'll notice the phone starts of slow but as each second passes by the charging speed rises. Also expect charging to slow down on heavy uses such as gaming and when the phone is hot. I think you should be fine as long as the phone continously says that it's super charging at all battery levels. Expect a 0-100% in about 1h 20 minutes.
Below is an example of the max current speeds I get out supercharging but note that this varies slightly depending on battery percentage.
This happened to me too ?
It has been 4 days since my phone got wet and it still doesn't support suppercharge. What do I do? ? Currently charging at 1700 mA according to Ampere

Have some patience. As long as the phone displays supercharging in the lockscreen it's fine. It's also possible that there's still moisture in the charging port/battery area that the phone detects which is preventing it from supercharging. I recommend drying the phone thoroughly and waiting. If it doesn't work within a week I recommend factory resetting your device and/or trying a different cable and adapter. If nothing works, i recommend taking your device to the service center. I have personally experienced this myself and the issue had resolved itself within 3-4 of occurance.

Yes, Charging will appear and then the device will say SuperCharging and will go back to Charging a split second after. Haaaay. This is so frustrating. Today marks the 5th day

I had the same issue, except that before it wouldn't say supercharging for even a split second and it would only say charging. Overtime though, the phone eventually started saying supercharging for a split second (just like in your case). I feel as though this is a good sign.
Avoid charging your phone overnight if you can, it isn't good for the phone, heat etc, supposed to shut off and not allow anything through but it still does and it's best avoided.
In regards to your device not taking the full effect.
It does actually sound like a fault, allow a complete discharge (also something you shouldn't do) then give it a shot, plug straight into a wall rather than an extension.
Other than that I'd say RMA.

It's been proven that keeping charger connected at 100% charge does not damage the battery and some times it's even good to discharge the phone completely so battery is 0% since it helps the battery and operating system to keep proper % level registered. Since it has happened that battery begins to think at 45% is 0% and 100% is 100% so when it reaches 45% it shuts down and tells you batter is empty 0%. This is because battery has been miss calibrated in the operating system which has an file that registers which point battery is empty and full. So this is why emptying the battery fully few times does help calibration to stay correctly with 0% as 0% and 100% as 100%.
For the OP it seems somethings odd with supercharge, could be USB port on the phone, USB controler on main board or the charger and cable.

OMFG there is always one, Lol i'm not going to go into this any more than i absolutely have to.
To put it mildly, you're completely wrong, and i don't care what you've read, please understand physics, if you push power towards something and continue that pressure, whether electric or otherwise, something has to take the brunt of that force, capacitors can't do this forever, which is why they burn out.
I've worked in the mobile industry for over 20 years, i've seen what 6 months of charging every single device on the planet does EVERY SINGLE TIM, iPhones down to nokia 100's
Please don't go on about this, i've seen this 1,000's of times on 1,000's of devices.
Your battery will either bloat or lose efficiency, or your actual device will inherit anomalies, i really do not have time to type what i typed nearly 10 years ago so you can understand.
Don't talk to me about capacitors, which is the only thing which is stopping that charge from getting to the motherboard of the device.
The only reason you should charge your device overnight is because your provider wants your device to die so you can buy another, and that's IT.
I've seen a battery which was a highly rated lithium battery stretch a device in half with industrial sized screws, the battery stretched from 0.4" to 2.2 inches.
The only thing i did was to charge it a lot and it split the device in half (same device used to diagnose mercedes benz cars and BMW's)
Please don't drop "it's been proven" in here, you're very very wrong and the only person you're helping is your provider.
You make your decision who you'd like to listen to, i can't be arsed arguing any more than i already have.
To the OP.
RMA your phone, that's not right.

To bad for you then, since your fact are wrong. It's been proven my bigger professionals out there that it's a myth that battery gets damaged when keeping charger connected at 100% since when it reaches 100% charge point it will stop charging the battery, but mobile will still be running from Charger. So yeah just admit you are wrong, i'm not the one that's wrong.
Also they did say one thing, damage did occur only on very old batteries that exsisted years ago, then those kind of batteries couldn't handle and would become damaged when charger was connected at 100% and it was different type of battery back then as well. Now we got something called Ion battery which can handle the full charge better than old batteries did.
Also idc how many years you been working with phones, alot of people still think wrong and have wrong facts still.
But now your words are against over 10 or more proffessionals out there that has proven opisit answer, so yeah just admit you are one with wrong facts.
Not last but least, alot of people take old facts with new batteries and still belives that battery are affected same way. But answer is no it isn't affected same way. lithium ion is another kind of battery we use for quite few years now. But before lithium ion came then it was a another kind of battery that did not handle itself well with 100% charge and would easily wear out alot quicker and get damaged.

Lol ok as I said I'm not going to go into it
You overcharge your phone and see how you get on.
Tell me have you ever got anything close to these battery stats for SOT
https://forum.xda-developers.com/oneplus-5/how-to/screen-time-leaderboard-post-longest-sot-t3780178
14 hours 20 mins?
No I know you haven't
You carry on and I'll do my thing.
Max up time for an iPhone 6 183 hours.
That's a week to you.
I know you have never seen these numbers.
But whilst you're sitting there with your head in the sand overcharging your phone every night lol.
Spare a moment for what you could have.
Don't spread crap without proof.
I have tangible proof I've seen and had to replace devices because of it. Screens, batteries, buttons.
I've seen more kit then you'll ever see.
You carry on the way you are but don't tell people to do what you do. It's idiotic and until you realise that you'll believe what you've read.
FYI you're relying on capacitors.
The second they fail your screwed.
Lol lithium is lithium..
You charge it it expands, please try to understand the logistics and dynamics of what your are attempting to talk about.
Or I'll tell you what, you keep overcharging your poor phone and I won't and we'll see who's phone lasts the longest after a year. I promise you I'll put you to shame.
You're taking someone else's word you don't know over someone with first hand experience of this behaviour
On your head be it
Supercharging Works Again!
So after 11 days my p20 pro's ability to supercharge is back and Im so relived. Thanks for all your help!

It just appears randomly. When I was at work earlier, it worked. But now that I'm home and I plugged in my phone it doesn't work again. It just promps every once in a while. It's like trying to supercharge and something is stopping my phone from doing it
my pro had a swim last night, and now it doesn't charge at all..
