[Q] Charging glitch [test your device] - HTC One X

Dear XDA members,
After using my hox for a few months, (i absolutely love it..) i noticed a weird glitch..
While using my hox through the day, its fine.. i have no problems at all.
but: when i charge it at night, and use it before i go to sleep.. the problems occur.
problem 1: overheating while charging, phone gives an warning with its led (red-green-red-green)
problem 2: this problem is more instant, shaking when scrolling..
its the last problem that i really hate about my phone, if it charges my touchscreen becomes "shaky".
if i open a web-browser and scroll without charger plugged in.. everything is fine.
but if only the metal housing of the usb plug is touching the chargerport of my phone it starts doing funny stuff..
if i keep my finger on the screen, (after scrolling.. when i just stopped moving my finger across the screen)
my screen scrolls up and down very quickly.. and wont stop doing this untill i let my finger go.
this results in an vibrating effect.. like the text is vibrating in my screen..
but when i unplug the charger.. this problem is gone!
then add the overheating problem, and my phone becomes pretty annoying while charging..
its burning my fingers (while charging it will get up to 50 degrees, just by using youtube..) and i cant read normally with one of my fingers
touching the screen, because it will vibrate.
does anyone else have this problem?
i have the HTC_E11 (western europe) and im running android 4.0.4 (stock, unrooted)
besides that, i did not unlock the bootloader.. its like it just came out of the box.
note: this only happens with ALL wall chargers.. from different brands.
(2 htc chargers.. one from my old wildfire S and my new charger AND an samsung galaxy tab charger AND archos tablet charger)
this does not happen when plugged in to an pc, so i think its an grounding problem?
same with browsers.. this happens with all apps and browsers that have the functionality to scroll.

Well about 1,5 years ago I had a spare Motorola charger which was only 0,5A out, but used it when some friends came over and use my charger.
Both my old HD2 and my gf's Desire S became fuzzy with the screen when its plugged. It was clearly mis-tapping where I tap my finger, by very huge margin.
It reminded me that. The charger was rubbish.
mostly trying to avoid using any mobile device while charging but I did play angry birds while charging my HOX a few times, don't remember such a heat.

My HD2 used to respond incorrectly to touch with the stock charger. My HOX doesn't do it however, But if I plug it in to my HD2 charger it sometimes goes a little crazy.
It's easy for electromagnetic interference from a transformer mess with the digitizer in the screen. This is true of any device with a capacitive touch screen.
As for the shaky screen, that would be caused by noisy power being generated by the transformer, rather than a nice clean sine wave. This is common when you overload an AC/DC converter power supply. Try using one that's rated for 1.5mA and see if it helps.
It's unlikely it will damage the device, but it will charge less efficiently and cause some crazy behavior while it's plugged in.

i tried it with my 5v(usb), 1.5A adapter that i got with my tablet..
same problem, but overheating of the accu gets a bit worse
my original adapter has 1A, how much ampere does your adapter have?

I usually charge with a 1.5mA charger. Having said that, a lot of chargers seem to just have a random number stamped on them. I have seen tiny little chargers that claim up to 5A and only actually supply 500mA or less, so they get very overloaded.
An easy way to tell is to see how hot the power adapter is getting. If its appropriately rated for the current draw of the phone, it should get a little warm while charging. If it's getting hot, it's not up to the job and should be replaced.
The charging current should be limited by the charge circuit in the phone, so the higher the rating on the power supply you plug in to to charge, the cleaner the sine wave should be and the less issues you should get. The phone may just get a little warmer when charging due to more current being available. Again, this should be limited by the phone though.

The charger output is DC, I'm not sure what sine wave you're talking about.

[Q] Ipod/Iphone charger results in buggy touchscreen?

I think nobody asked this question before since I didn't find it even loking in Google
Since I got mi Desire I realised that not every charger works for it, I have an USB charger that went with a bluetooth dongle I bought (with same specs) but seems to be a lie because the battery keeps draining when plugged in, but that's not the problem I actually have.
My original HTC charger broke after three weeks of normal use , since there are no HTC stores in my country I went to an Apple store and bought and Iphone charger wich has the same specs as the broken stock one (Output 5V 1A). The problem is that sometimes when I plug the phone (usualy I charge my phone overnight), the screen becomes buggy, sometimes not responsive and sometimes over responsive (eg. if I click on an icon to move it into the home screen, it responds as if I clicked that icon several times very quickly). At first I thougt it was a ROM issue, but at this moment I already tried LeeDroid, OpenDesire and now I'm on teppic74's rooted Froyo and had similar issues in everyone of them. It's not really a mind breaker since I am ussually sleeping while charging, but I wonder if I'm not killing the battery or causing any kind of damage to the phone.
Can anybody give me a hand on this?
Thanks
Why not just order a charger online?
I don't know if it hurts the phone or the battery.
But if my screen went super-laggy and over-responsive by charging it..
I'd throw the charger out.
Already ordered, but I was wondering if someone happened to know a technical reason for this to happen, the phone doesn't overheat and the charging process works as a charm, the only issue is the screen wich sometimes behaves perfectly normal
Guess I will give the charger to any iphone owner when I get the original one (I have to buy in the UK store.. totally overseas)
My phone does the same thing if I use a PS3 charger (Just the usb to wall socket part). When I was in a phone shop, I noticed their Desire HD that was on display did the same thing. From what I can gather, it doesn't do any damage and happens with a lot of aftermarket chargers. Don't take my word for that though, hope I shed some light
Hello
Have same problem with my recently buyed HTC Desire while charging with non-original charger (from Nokia).
First time I'm worried about phone, but after reading charger's characteristics I found some difference in power.
So I think while phone charging it's receives less power than needed for normal work.

[Q] Touch goes crazy when connected to power

Hi there,
well, it depends a little bit which charger I use but one some I have the bad experience that when I have the phone connected to power the display just goes crazy. Means that as long as the display is turned on it pushed/touches automatically some areas in the display without stopping. So when I want to do something I have to disconnect the mobile first and than I can work with it.
As someone similar experience or knows how to solve it?
Thanks
Stephan
btw. it happens also with different mods
LOL same sh!t happened to me today too.
I moved in another USB slot from PC and seems that issue is gone. But until today I didn't had this issue. Maybe is the polarization +/- from the charger.
Happens to me also with an universal charger. Touchscreen is almost unusable while charging and laying on the table. But seems to work fine if I hold it with my hands (grounding the aluminium body). This happened also with my Motorola Defy with the same charger. But it didn't have any metal components on the outside so it didn't work correctly in the hand either.

Scary
Hehe, first time I saw this was so scary, ghost in the phone.
That should be the charger. I have two non original charges one of then with 1A and the other with less. First of then affects the screen sometime and the other never gave me that issue.
Hope this helps.
Yes. It's because of the voltage fluctuations that the screen starts to react weirdly. The same happens when you use a non-standard AC supply too. Don't keep using that charger and/or USB port for long though.. it will cause damage to your phone screen and more so to the battery.
Yes, specially with blackberry chargers

[Q] screen randomly awakens

Once my galaxy nexus is taken off the charger the screen keeps turning on and off displaying the lock screen. Periodically when the screen is off and not charging it will begin daydreaming. The phone will no longer charge in AC mode, only USB when plugged into in AC outlet. Does anyone have any ideas what might be causing this? My thoughts are the usb tongue might have damage due to using another charger other than the one that was shipped with it. I hope this isn't the case since one of the nice things about android is most devices use nearly identical chargers. If it is, how can it be replaced and what is the difficulty?
The weird thing is that once it reaches ~50-60% the screen will stay off, but once it drains more down to ~20% the screen starts to come on again

[Q] HTC infamous Battery charging bug with M8

Just got my M8 first time I turn it on it had half charged battery. I drained it to a point when I turned it on two times and than it went dead. I mean I could not turn it on. When I connected the charger no light came on and no response from phone. I leave it till toomorow and see if it will turn on.
I fear HTC is using the same chip for controling battery charge in M8 which if flawed by infamous HTC charging bug. If this is the case it is really start annoyng me and htc m8 will be my last HTC phone. I had so far Wildfire, Sensation ,Desire and all off them had a charging bug. Wildfire and Desire would not show the battery full even though battery voltage was at full charge. My luck? Or HTC has some poor quality components? My S2 still charges battery fine till today.
Ok. Anyone can check their M8 if you have charge bug if you battery is almost drained off power if it will turn on or stay dead?
If my won't wake up tommorow after all night at charging I'm gona exchange it on warranty and see another sample has the same charge bug.
Why HTC is not doing something with this CHARGE BUG on the newest devices? Puzzeles me.
I brought mine to 1%, cycled the power, then used it again till it died. Plugged it in, charging icon came on right away, charging light as well. Hope this answers your question, I didn't really read the whole post.

My M8 has just died because it wont charge, happened just yesterday. I left it plugged in over night and still nothing. Its a holiday here at the moment so have to wait until Wednesday for HTC to open.
Possibly The same Problem, Possibly Not?

Hi.
I've been having loads of problems having unlocked, rooted, S-Off, SuperCID & installing the ARHD ROM on my M8 (International) but it was, in a fashion, working. I too am on holiday & whilst I now know why I was having the issues & have the solution to them, I didn't have time before I left to resolve them. So, I brought it away with me to use for basic currency conversion & translation tasks & it was, as I say, functional. Last night, I decided to play a game on it & it was being laggy but I put this down to the issues I've been having, so didn't worry. It kept being laggy, so I tried restarting it to see if that would help but once it had powered down, it took ages to reboot, so I tried using the power button to switch it on. Again, it took ages & I briefly fell asleep but when I woke up, it had booted back into ARHD, so I figured all was okay.
However, when I awoke this morning, the device would not switch on. I plugged it in to see if something had caused the battery to drain during the night but nothing happens; the charging light doesn't come on & it doesn't power up, no matter how long I leave it! It is, to all intents & purposes, behaving as though it is dead (bricked?) but I don't know why it should suddenly do this, which is why I was looking for answers & came across this thread.
If anyone has any bright ideas, I'd be more than grateful to hear them
Mine needed a replacement charging board and chip unfortunately but HTC Vietnam was pretty fast, only took 3 days so wasn't too painful.
I like how "Happened to three people" == "infamous."
Yes, this sounds like a very isolated bug/defect. Since it is not reported by very many, the best course of action is RMA. ?
My T-mobile HTC ONE M8 has done this as well, however I was after serveral hours of trying everything I could think of, connecting it to the computer and various chargers and trying to hold volume up and power and replugging it to charger, it finally started charging. This has happened 2 times in the last 2 weeks.
Now that it's charging I wonder if HTC will take it and replace the charging board or battery. I also worry that I have it rooted and s=off that they won't honor the warranty.
There is something similar to this going on with mine - Was charging (maybe quite slowly), battery very low, phone reset. Booted into charging screen, amber light flashing. After a while (and trying to boot a few times), no light, nothing. Charge current is 0.00A
Edit: I remember something like this with the old Desire - there was a trick to reset the charging circuit, which was maybe locked up and not getting a good po_reset, so never enabling any charge. Something along the lines of unplug, hold some buttons for some time, plug, profit... Does anyone remember this in detail?
I had the issue in this topic, and got it solved.
Here are forums where I have found similar case and solution.

I have a particular case. My phone is a HTC One M8, but I have protected it with a special case with a battery extension, home made. I have assembled myself the batteries, chargers and boosters. My booster has a small issue and does not enter safe mode when battery is low. It warns about low batt with a LED, but still tries to deliver 5V. The booster is connected to the phone via a flat cable, stolen from a wireless charger; those chargers have the smallest USB plus I could find ever, and, I found this plug only in these decvices.
When the main battery of the phone is empty, I switch the booster on, and recharge the phone with the backpack. I have to look at the LED; when it's red, I have to switch it off. Everynight, everything get charged on the same single plug. One plug to charge both batts.
The advantages of my solution are:
- phone can last 18h with heavy work (wifi, bluetooth, GPS, and screen on, continuously)
- heavy case to protect my phone, plus tampered glass
- one plug to charge everything
- the micro-micro USB plug is ALWAYS in the phone. This means, the female plug of phone can not get dirty, or filled with dust. I never unplug it, so it does not age. I never plug a classic USB cable directly in the phone, so, no chance to break it. I have broken 3 or 4 times the back charger plug; if I am in hurry, I can exceptionally charge the phone directly; next day home, I can fix it.
This night, I was using my phone, and switched the backpack on. I could not plug my wall charger, because it's home made, has an issue, and makes the virtual keyboard erratic. I fell asleep with the phone in my hand, and the backpack went red ... for 4 hours. During 4 hours, it was trying to deliver 5V, and failed at so. Since my battery was delivering an unstable +5V, the phone was trying to charge, was staying on, but could not properly charge. In the end, all batteries got flat.
This morning, when I woke up, I plugged the stuff; only the back-batt started charging. Phone itself refused to charge; screen was black, and charging LED stayed off. So, I fell in what we call the "phone refuses to charge".
But, because of my set-up, I can *NOT* be in the dirty or broken plug case. Just impossible. And because of context, I just knew I had a flatt battery. This is technically called "deep discharged". And it contributes to aging of batt. Like overcharging, this heavily affects the total capacity.
I knew I could fix the issue by opening the phone, and putting a LiPo charger directly on the batt lines. I have loads of standalone chargers. I had a standalone wall charger for my previous HTC Sensation. But with the M8, we can not just open the case, and take the batt out. It's much more complicated. So, I have been Googling for more than half an hour. 95% results were about "remove dust of plug" and "bring it to the shop to change your plug". Some people also mention "a bug in the charger chipset".
I have plugged the phone on a classic USB charger, but via an USB meter monitor:
dx.com/p/382581 (dispite description, the device can accept up to 13V on input - this detail is critical when you use real QC2 chargers able to deliver 9 and 12V, like this one:
http://www.amazon.fr/Chargeur-secte...&qid=1451509059&sr=8-4&keywords=aukey+charger
http://www.amazon.fr/batterie-exter...&qid=1451509059&sr=8-5&keywords=aukey+charger
)
The USB meter was indicating 5V 0.03 A (or 9V 0.01 A, depending on source). So, the phone was using a bit of energy, but clearly not charging. I have left it 4h. Just in case, can not harm.
Then, I pressed together power, and volume up. The phone started to boot after 55 or 65s. About one minute; but clearly way longer than 42 or 47s found on forums. It started directly to some rescue mode, then, started to boot normally, without doing anything. Just released buttons during the first white screen. After booting, I have a normal phone. Did not need to perform any action. During boot, the phone had 2% batt, and was charging normaly. But, the charger LED remained off; I waited 5mn, untill I got 4%, unplugged the charger, replugged, and then got the orange LED.
Remember that your M8 can accept up to 9V on input. QC2 Chargers are really faster: with 9V 1.5A, you can charge your M8 from 0% to 100% in 95mn, even if you are intensively using it (gaming, wifi, GPS). Next gen phone will accept 12V. Even if manufacturers ignore that. HTC buys chips, and don't fully read specs. Aukey chargers are more powerfull and better reliable than official HTC ones.
Remember that many "slow charging" issues are in fact due to bad cable: charger is good, phone is good, but cable in between has high gauge copper, too thin wires, and produces voltage drop between plugs. HTC phones require 4.4V at the plug.
Remember that M8 and most modern phones (same for Samsung) are now MHL (wrongly called OTG): they are true USB hosts; you can plug any device on your phone; just buy an MHL (OTG) cable for 4 euros, and then a USB hub, and then any device: mouse, keyboard, USB monitor, ethernet dongle, SATA adapter, CF-uSD adapter ... and for 12 euros you have HDMI converters. Modern smartphones are real computers. Use them.

General Pixel Stand 2 stops charging

This started happening a couple of weeks ago, prior to the latest update.
When I put my P6P on the Stand 2 at the end of the day, I get the little sound and animation that it started charging. After a few seconds I see the message at the bottom that it's "charging wirelessly" and a time until full. I have the stand set on Max Charging and adaptive charging turned off. After a minute or two, the fan comes on. About 10-15 minutes later, it stops charging, (the message goes away and the current % is shown), and the phone is really hot. No matter how long I leave it, even overnight, it never starts charging again. The phone remains really hot until I remove it from the stand.
About 50% of the time, if I reboot it, it will behave normally again, but last night nothing I did would get it to charge wirelessly. I ended up plugging it into the wire. It never gets warm when charging on the wire.
It has been working fine since I purchased it in Nov. This just started a few weeks ago. Has anyone else seen this?
Dave
Try cable charging.
Charging will disengage if the battery temperature gets too hot, about >103F
Fast charging may disengage if the temperature gets beyond 95-100F.
Ideal charging battery start temp is 82F.
Erratic charging can indicate a failed battery.
Any swelling is a failure, replace asap if so.

As indicated in my OP, cable charging works fine every time. The phone doesn't even get warm. It's only wireless charging that's an issue, and not every time I try to charge it wirelesly. It's like the phone decides to stop accepting the power, and it starts to heat up because of it.
I take it you don't have a second wireless stand to rule out if it's the phone or your STand 2 that's behaving badly?
I have been using a genric set-up from charger to stand with my P6P and did have charging issues a few months ago with wireless charging not working correctly but the May update fixed it.

May be a hardware failure in the phone or stand.
Remove a case if it has one and try.
C ports generally last for thousands of charge cycles and cable charging is better for the battery, produces less heat.

No, unfortunately I only have one stand. I'll keep trying things to see if I can narrow down the exact situation when it occurs. I was mainly checking to see if anyone else had something similar happen and there was a quick fix.

Yeah, and I've always used cable charging on all my phones in the past with no issues. I thought the stand was cool in that it could fast charge and keep the phone upright so it's easy to read in the middle of the night. I'd really like to keep using it. It was stupid expensive and I'd hate to let it go unused for that price.
Thanks!
Dave
I've been experiencing similar problems with my Stand. Sometimes it charges normally, sometimes it charges REALLY, and I mean really slow... And sometimes I get the "Not charging" message for whatever reason.
I think it's gotta be an issue with the adaptive charging on the Pixel 6 Pro, because every time I put my other phone on the stand, my S21U, it charges without any issues.

Yeah, I feel you. It could be firmware, a SEU which are rare but do happen. A reflash would fix it if so. Probably not worth the trouble to try and more likely to be hardware.
Cable charging be the best plan for now I think.
The old micro connectors were horrible and invariably would fail. The C connectors are much more robust. This N10+ is heavily used and the C port jack is still tight and has well over a thousand cycles plus a few drops and pulls. Even the original cable is still AOK.
Just came across this thread while looking for similar problems on my P4 with a 1st Gen stand. The phone showed the normal 'xx% charging wirelessly' display then at 79% it changed to simply '79%'. After a while the message went back to 'xx%charging wirelessly'. I took the phone off the charger and using a utility app called 'inware' I looked at the battery temp which was at 41.5C/106F.
So I'm guessing that the phone will stop charging when the battery gets hot and resume when it cools down a bit. What is 'too hot' and when does it cause damage, I have no idea. Google told me in a chat session the other day that it's perfectly acceptable to leave the phone on the stand all day. Personally, I take it off at about 80% charge which lasts me all day.
Mine also has this behaviour, taking it off and placing it back on continues to charge
I just sent my stand back for similar reasons - not good when a $12 Qi charger from Amazon was doing a better (and faster!) job charging.
I sent mine back too & am now using a charger that I bought at IKEA for £5. It's a shame as I thought that Google would have made more effort to integrate the charger & phone. Oh well, bling gone!
