Defective charger? - Nexus S Accessories

I bought a dock and wall charger from Amazon a few weeks ago for my Nexus S. The dock works fine, but when I plug my phone into the wall charger it makes the touchscreen do very odd things. It starts to get very laggy, and it also seems to misjudge where I touch or tap by a great distance. When I unplug my phone from this charger it works correctly again. This problem doesn't happen with the charger that came with the phone itself. Any idea why this could be happening?

The charger you bought is likely not sufficiently isolated from mains. Some part of the mains frequency might leak through and confuse the touch sensor.
Mind, I am not saying that it is not safe to use.

Sorry to come into your thread to ask a question.
But I have a question about charger too.
At home, I use the original charger that came with Nexus S. My battery seems to last very long.
At dorm, I use the so called Samsung charger I bought from eBay [it says it's legit and it sure looks like one] but battery doesn't seem to last as long as I would expect.
Settings and usage/variables are not exactly same but - for example, I got 22 hours with 40% left with home setting, while I would have to charge my phone usually after 6-8 hours at dorm.

Try swapping the chargers to test. But I honestly think it is not the charger's fault, if your battery is full both times. More likely there are other circumstances, like bad reception, or your phone is searching for wlan all the time or whatever. Try going to the battery monitor in settings somewhere, there you can see what it using power. I can't direct you there exactly because I have a non-english language running.

As I said, your charger very likely is just as safe as all the other Chinese electronic stuff. It is just not filtered/stabilized enough and so it confuses the touch screen. Keep in mind that the touch screen works by sensing a very small capacity change. Some overlaid interference can probably easily disturb it.

Battery drains quickly... while plugged in! wtf?!

okay so this is a new problem... if I plug my tilt in to my car charger, the battery actually drains faster than if it's unplugged... about a percentage a minute... when I come home and plug it... it charges regularly. I've tried 2 different roms, 3 different radios and 2 different car chargers... any ideas? been doing a lot of soft resets lately, wondering if that would burn the battery out?
new revelation!
okay so after my car charger "drains" my battery... I put the regular charger in and charge it from 74% to 85% in about 20 minutes... then I took the battery out and put it back in.. upon reboot my battery is at 97%... does this mean the car charger is somehow ACTUALLY charging the battery but for some reason making the phone think it's discharging it... this is tricky.

is the battery heating up while it is charging in the car?
I don't think so... I'm not 100% but I'd probabally remember something liek that
I just remember it was dropping like crazy after I plugged it in.. once it jumped from 39% to 34% when I was using it while it was plugged in for 4 minutes

sorry, should have asked in my first post but are you running TomTom or similar?
no, no abnormal software... even turned off the 3g and wifi... I'm starting to think it's not actual battery drainage because of how fast it's dying.... it dropped to 2% and shut itself off last night when I plugged it in.. took 5 minutes to go from 28% to "dead" then when I was charging it in my house that night it slowly went from 0% to 45% then it jumped to 98% and was full.. I'm so confused
Maybe let the battery drain out all the way so the phone won't even turn on, and then charge it back up. I've never heard of this happening before, but I know the phone has to "calibrate" the battery, for lack of a better word. Draining the battery all the way lets the phone set a "zero point". I dunno if it will help, but it would be worth a try.
haha it kinda did that on it's own last night... recharged it, it's got the same problem as of 20 minutes ago.. maybe it'll work itself out.... but I really need to be able to plug it into my car.
This is my second Tilt I'm playing with as the first one after I messed around with started to act funny.
1) Battery would be 100% - I wake up 6 hours later and it's dead.
2) Network consistently was being dropped even though it stated I was connected.
I've spend 5 hours on this site reading now and still don't know if I've learned much lol
Good luck to you...
Check the USB port. Is it slightly bent on the right side? I had this same problem & had to RMA. I confirmed that there was higher discharge using SK Tools & Anton Tomov Batery Meter. However, home charger still worked fine.

YES! the usb port looks a little messed up on the very last pin.. WTF? it looks squished or something... RMA? that doesn't sound good.. I hope I dont have to RMA... what's RMA? but yes there is definately something messed up about the right side of the USB port

Hmm... I would charge to 100% (or near enough) unplug it and then put the media player on and play it solid on repeat until the battery dies. Then charge it up to full again and see if there is any difference. These batteries don't have a memory as such, but as the previous poster said it may have got itself slightly 'confused'
Same problem here with a carcomm cradle for the TyTN II,. When I plug my phone in, the orange light comes on, the phone says it is charging but the battery just seems to drain faster and after a couple of minutes the light goes out. I have BatteryStatus installed, when I connect the phone to my pc with the standard usb/synch cable BatteryStatus shows +0mW for a short while and after a few seconds it'll say it's at +1300mW or something like that.
In the car when I put the phone in the cradle it'll show +0mW for a few seconds, then around -250mW (Idle) and the orange light turns off...
But I actually caught it charging once with +22mW when turning it on (from standby). I tried all obvious things, softresetting the phone while charging etc. But nothing helps, the cradle is connected straight to the carbattery.

What kind of carcharger do you have? Been reading about this problem and alot of ppl say the charger needs to be able to put out at least 1A for the phone to charge, I used some cheap cigarettelighter charger that was rated @ 650mA. It worked but charged so slowly that it would've taken days to fully charge. And besides that it didn't last long, 3 days before it blew the fuse and some more parts (worked for 2 secs after replacing the fuse)
I've tried several different ones... I think that since 3 people on this site all seem to have a "crushed" pin in our USB ports that's probabally the issue... now.. about a fix...
The amperage on your charger doesn't really matter. 1 amp is recommended so that you can use the device while charging, and the rate at which the battery charges does not diminish. If you used a 500mA charger, and had wi-fi & gps on, and media player blasting, for example, the battery may not charge at all because all the power coming from the charger is being used immediately. 1 amp chargers remedy this problem. Hope this makes sense, I've been having problems finding the correct words to express my ideas lately. Probably just stressed out! It sounds like the bent pin on the usb port may be resulting in a V+ pin shorting to ground (or V-). Which would drain the battery quickly. When you use battery power or charge the battery, it is normal for the battery to get warm. When you plug yours into the car charger (the one that drains it) does the battery get abnormally hot? This would indicate a short. Maybe try to put a real thin piece of film or something under the bent part of the port to insulate it while charging and see if that fixes it. This might offer a temporary fix until you get a new port. Maybe you could spend some time learning how to solder! I had to fix a broken port on a wizard a those solder points are friggin' tiny. Hope I could help. Good luck.

this sounds like it makes a lot of sense... I've got big clumsy hands, man I wish I had been more careful... well looks like I'm gonna be out $80! but quick question.. why would the wall charger operate normally while the car charger reverses charge?

[SOLVED] Phone Stops Charging Randomly. Solution?

I noticed this as of yesterday. My Nexus One is plugged in to the wall charger right now, but it randomly stops charging. The light at the top disappears and the phone shows that it is not charging. Give it a few seconds, and it starts charging again. Sometimes it will charge for 30 minutes without a problem, other times it starts and stops every few minutes. I've tried messing with the cable, but it doesn't affect whether or not it charges. I plan on switching batteries with my brother to see if that has a change. I'll also try a different cable soon. I've already rebooted the device, no change. If you go to the battery usage chart, it shows huge gaps in the green charging area..
Rooted, running geo411m stock rom, Android 2.3.3, stock kernel, stock HBOOT.
Any ideas? I hope the charging circuitry isn't failing. Took like 5 hours to charge, now the phone is at 95% battery.
I would try to wipe the battery stats from recovery see if that makes any difference then maybe try full wipe 1 to 5 times and maybe a clean install or even just change ROMs and check if it's the same.
alright I'll give those a try. I just don't know what could have caused it to happen. been on this rom for months, no change in setup. just randomly started. seems like a software issue to me (hopefully not hardware). even right now as I'm using it, it's plugged in but not charging.. 81%, no charge light.

Your charger or cable are most likely the culprit. When the charger doesn't provide enough current - the phone stops charging, and sometimes chargers fail.

It was the charger! My brother has an official HTC one he bought off eBay (looks like this), whereas I have the one that came with the N1. His charged my phone fine. My charger was still screwing up with his phone. I'm just going to buy the HTC one now. Thanks for you suggestion!

Call HTC, even if you're out of warranty. They have been exceptional in providing replacements for broken accessories. I had somehow cracked the lens in the battery door, and when I called to ask where I can buy a new back cover they simply asked for my address and told me I could expect one the next day. Worst thing that could happen is they say "no".
I was searching an answer but found myself. The issue is something happen to system because of unstable voltage then keeps turning off charging.
I've added agni control kernel and activated ignore unstable charging power and voila!
I know this is an old thread but can you tell me - if you can remember (!) - how did you acticate "ignore unstable charging power"? I have the AGNI kernel for my Xiaomi Redmi Note 5 but no idea where the settings are! I've heard of an app but where it is I don't know.

[Q] Unresponsive Screen Charging

I've been using third party chargers for a few days since my original email charger broke. However whenever I'm using the phone with a third party one the touchscreen is a bit less sensitive and responsive. However, I as soon as I take it out it behaves as normal. I wonder if this happens to anyone else? And also can it cause long lasting damage to the phone?
I too have the same problem.. its not that quite responsive when its charging.. Im using by the way the latest stock LC2.
I think this is inherent irregardless if your using the stock charger or any 3rd party charger for that matter. This issue is not on the chargers actually but on the 'laggyness' on the Note's screen when your using it (while it's charging).

+1 Also observed this when charging from a friend's HTC charger, also read a thread about this a while ago, although there was no definitive answer from what I read, just people reporting the issue...
Sorry mate, no solution from me, but you can be sure you're not the only one experiencing this issue.
I'd imagine it has something to do with the fact that the charger may not be able to supply the power that the larger Note battery needs...
LE: No, charging with its original charger or my S2 charger, or even my Galaxy Ace's charger does not make it less responsive. HTC charger...does
Used to have same problem with iphone too. Cheap Chinese chargers have same effect.

I think from a simple deduction, when your charging, your actually charging the phone's screen itself. Now this maybe wrong but I've read somewhere that what's mainly holding the power on all touchscreen phone is the actual screen itself.
So if your charging the phone, your actually charging the screen and if your using the phone(naturally using the screen itself) you are in effect disturbing the charge because the power it needs to fill up to recharge the phone is being use also to discharge it (thru constantly using the phone itself.)
This is an issue with many android devices. And some do it even with the OEM charger. I've personally experienced it on 3-4 of my phones.

This happened on my HTC EVO even with the factory charger.

I think if I'm not mistaken.. this all happens to all touchscreens out there, irregardless on what brand or make/model your using.

Sorry, but this is bull****. Phones have batteries like any other portable device, and this is what is charged.
I am speculating entirely but it is most likely that the voltage coming in from the USB cable is ****ing with however the screen detects your finger (i.e, via capacitive sensing). More speculating but I assume that having some sort of electric field near a capacitive screen will cause issues in detection (I've had the same effect happen with the capacitive buttons near a plasma ball; they caused false detections of the button being pushed). Then again, the phone is full of electronics + radio transmitter so I might be wrong.
Basically, buy a better cable, or it might just be a general fault with this sort of thing.
My HD2's screen used to go crazy when I charged it with a Chinese charger, like random screen touches at warp speed. If I used a well made charger, all was well.
The touch screen did eventually die on the HD2, and I had to send it back for repair under warranty. Now, if I get any jittering/non-responsive screen behaviour, I ditch the charger.
I've experienced this too, but it is not necessarily the charger, but the amount of power delivered by the charger.
I used to live in a rural area and the power supply was bad. We only got about 150V through the wall socket instead of the full 240V.
Using my stock charger on my Galaxy S, the screen was laggy, but if I used the same charger on a good power outlet in town, it was fine.
I've also used cheap no name chargers that are laggy even on a "good" wall socket.

speculation and assumptions are just cousins..
Anyway, you are talking about capacitive sensing and stuffs. Capacitives and resistives only apply to touchscreens and none on qwerty phones. Your 'speculation' about electric fields on capacitive screens are actually correct, but I would like to go back to what I said again, the phone draws power from the screen itself. So when you touch the screen (to perform gestures on it), you are actually drawing out power from the phone. your finger performs a conductance to the screen. Your say of 'false detection of the button being pushed' are actually magnetic fields that is try extrapolate from your fingers (as a magnet) to the screen, thereby causing a marginal errors on the screen's predefine calibration.
That is why you may have notice that whenever you have your phone charge, and your actually using for example to type a message on your phone, you can clearly see a margin of seconds in delay when letters will be registered to your message.
Try to simulate that with the phone charge and when it's not. Clearly you will see what I mean.
this is what the word- ferromagnetism is all about.
anyway, I won't delved with that as it's in the realm of physics already.

Had this same problem on my Dell Streak5 when using a non stock charger. The fix at that time was to purchase the small longitudinal magnets that are made to surround and clamp onto the usb cable. I had to place two on the end closest to the Streak. Corrected 80-90% of the problem.
I got the magnets at Radio Shack. It's been nearly two years ago, but I think I paid about $6 for a pack of 2.

What? Only 150V? I don't believe it. How then other things work?
Sent from my GT-N7000 using Tapatalk
Well I was told it was 150V.
It took a lot longer to charge my phone or laptop there than it did at work in town (using the same charger in both locations), so there was definitely a lower current coming through.
Solved irresponsive screen when charging
After eight months trying to find a solution, today I have tried with my iphone 4 charger and my Kindle cable and, for the first time,I am able to write properly, as I weren't plugged. I have to say I don't like this device, it's very slow and the screen goes green almost everyday.
NICE GUY
Well this problem is not because of screen quality. Its all about with the wavelength of current supply and change in frequency . Its create some magnetic field and makes your screen behave weird. When we get proper ellectric supply we don't face such problems. Also cheap chargers don't follow quality levels and they generate uneven frequency thats why flux created by them makes screen behave weird.
This happened to my old HTC Incredible S (Vivo).
It only happened when the 5V charger was lower than 1A.
Quite strange.
But you could check if your charger has at least a 1A output.
Should be on there somewhere.
The stock Samsung chargers are 1A as well I believe.

Nexus 6 No Power No Charge, 3 days after using N Preview

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.

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.

Supercharge doesn't work

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..
