Weirdness when plugged into wall?

Anyone else having issues with the phone when it is charging on the wall? Screen transitions get really choppy and touch screen sensitivity goes bonkers.
This is driving me crazy!
Sent via XDA app | HTC EVO | CM7 RC2

I've had this with CM7 as well. It's super annoying.

I've had this with most if not all Roms I've used. It depends where I plug my charger in honestly. Some places the touchscreen goes crazy some places it doesn't. Why? Hell if I know lol. I was starting to wonder if I was the only one with this problem.

I have had this problem before, but it is gone now. Could never figure out the cause...
It was never specific to CM for me. I found that at times, setting setCPU to clock up to max (not necessarily OC) when charging helped a little.
But for some reason the problem disappeared for me. Not sure why to be honest.

My phone only lags when I have the sd card mounted to a pc

It happens to me when I use one of the chargers I bought from Walmart. I think its a grounding issue.

Happens to me on Cm roms with HTC charger.

Its an issue with the charger. I have two completely differnet phones and the same issue happens on both when I use a certain charger. It charges fine but touchscreen goes to crap. Both phones work fine on a different one.

+1. Works fine with the OEM charger. But a cheap charger I got on eBay that charges a battery at the same time that it charges the phone always causes the touch screen to become completely unusable.

Not the charger. I have the same issue with my evo connected to the stock charger. It doesn't usually happen right away. In fact most times for me it isn't until charging us complete before I see a slow down.
I could be mistaken, but i believe it's a heat issue. The heat from charging the battery causes the CPU to enter a slower, low power state. This in turn will result in everything, not just the screen, becoming laggy. I've also noticed the same effect on hot days during the summer, if I let the evo get hot (like leaving it in a poorly ventilated area or heavy CPU/graphics usage), I get the same slow down.
I have not tried using setcpu but I suspect that thermal protection will automatically override user defined clock speeds.
Of course, all this is just my best guess, and I have nothing to prove it either way.

Agree & Disagree.
From the world testing I've done I completely agree that heat is a cause that can cause the phone to act incredibly slow and unresponsive. I have accidentally left my phone in the car during summer, come back and hardly anything works
My disagreement is that I do also believe that the charger/charging effects the phone. Using the stock HTC charger I get an sporadic screen, sometimes immediately and other times delayed, while charging. It almost always shows up after a full night of charging (phone could/should be warm here, right?) but the moment I unplug the device it becomes immediately responsive (heat hasn't changed).
I don't know what the root cause is, heat I think is a contributor, but either way I just deal

I believe it's due to poor grounding, which affects the touchscreen.

Ive had this with cheap chargers

yep - its a grounding issue with the touchscreen caused by using a cheap charger OR a cheap cable OR a bad cable. It is NOT a problem with your phone. Get a nice OEM cable or a nice OEM charger and you'll be in good shape.

I remember when the Evo first came out there were grounding issues with the screen (hardware 0001), i.e. if you put it down on a bed or couch, you couldn't get the notification bar to pull down. I would also estimate that there are still some minor residual grounding issues still around. I get it every now and then as well, I'm also using the stock HTC cable and charger. However, that battery theory is a pretty smart thought.

and perhaps you're cable is bad. stock cables do go bad, I've seen a few people with bad cables. They can fail in numerous ways.

If it is the cable or charger, why does it not happen on the stock ROM? Temp makes no difference.
EDIT: This DOES NOT happen with the stock ROM!
Sent via XDA App

Same cable, same charger (both stock), same outlet, does not happen with the stock ROM, but it does with CM7. I've just tested this quite a bit. Temperature is not a problem, either.

It happens to me after the battery hits 100% (on a non-sbc kernel) using stock cables, and stock chargers and my computer's USB for charging. It never happens on the stock kernel.
I'm not sure anyone ever knew for sure what caused the rash of these back in June/July, but I do know when I created the first FPS hacked kernel back then, it mysteriously cured some people's touch screen problems even though my modification didn't even remotely have anything to do with charging/touch input code.

why wont my nexus 7 8GB charge?

my nexus 7 tablet just wont charge, im using the stock plug and usb cable provided with the nexus 7. It it on and says charging but battery percentage doesnt increase. As of now, it is on 0% and has been for the past 5 hours. I've also tried other usb cables and a motorola milestone charger/cable and still no luck, please help me.
thanks

I had the same problem. Check the charging unit and make sure the two sections have clicked together.

thanks for the info, yep its in there and clicked together, still not charging properly, i think its a dead battery issue

Have you tried using a different charger or tried charging through your PC to eliminate potential problems with the plug and cable? Just a thought.

Try to jiggle the cable in certain directions such as up down left right and see if it starts to charge. If it doesn't, return the sucker.

I have found the N7 is picky with cables' the default one that comes with it works fine but doesn't seem to want to charge through my car charger.
My epic4g cable doesn't work and neither do any of my other USB cables.
Same with the charger, it has to have a dedicated live connection and no USB splitters with multiple ports.
I need like a good 4-5' USB cable to use tablet comfortably while charging.

My car charger doesn't work either but my computer/tv/printer/tivo/wall/everything else works just fine... it must be a voltage issue with the car charger.

I remember reading that the charging issue some of you guys r having is a confirmed hardware problem, due to poor quality control. Asus was in such a rush to get the first few batches out that certain faults made it into a select number of batches. Other people who have had this hardware problem either could only use the Asus adapter, or that might not even work. You should try to get it replaced by your seller. I'll post the source in the morning if everyone's too lazy to Google.
Cheers

possible fix
I've read on other forums that it is the usb port. I my experience it is a intermittent connectivity or the wall wort isn't putting out enough amps. I bought an iGo Green for the iPad, put the tablet in Airplane mode and it will work fine while using it. Last night I shut it all the way down, let it charge overnight and woke up with a full battery.

Seems like only high output chargers work. All my 2.1A chargers work with Nexus 7, but lower output ones do not charge even when Nexus 7 says it's charging.

My 8GB arrived Monday , 1/2 charged pluged in to the 2A charger it says its charging but the battery just drops. Turned off and left overnight and its still no more than 20% charged.
I need to find an app that shows charging
check output of charger, check cables, check charge on phone vs tab then send back to Google for a replacement grrrr

I have the same problem, how do I fix? I have the 16 gb version.

The N7 seems to be having a lot of problems with charging. A couple times when my battery has been completely dead, I have had a tough time getting it to begin the charging process. One time I watched it begin to charge, then boot up, stay on for about 20 seconds, turn off, and then not charge. I have no idea what's going on. I always eventually get it to work, but something doesn't seem right.

Remedy
Google Play telephone support had be factory reset my Nexus 7 8GB. After the reset, the battery began charging. A major nuisance having to redownload everything, but it does work. Good luck

[Q] Car Charging Issues with Nexus 4

Past 2 days my Nexus 4 is not charging via Car Charger, i have original Samsung Charger, i also have USB port. i tried the USB cable i receievd with Nexus 4 from LG. No Luck, i can only charge my Nexus 4 at home.
I checked my usb lead and Samsung Car Charger to charge my Backup phone Galaxy mini, it works fine. Gaalaxy mini charges but not my Nexus 4.
I was thinking it might be an issue from CM Kernel. i recently installed CM10.1 nightly 13/3/2013 it was working fine before going custom rom. I have used every single custom roms in the past, i had no problem with charging anywhere before.
so i returned back to stock today and it is the same not charging.
I can only charge at home, but i use it alot and i need to keep it on charge in the car too.
Help pls thank you

Lower amp car chargers can't charge the Nexus4 faster than it discharges. I have a 2 Amp charger that works.
Having the screen on full brigthness while using GPS drains the phone really fast!
Does your Nexus4 not charge at all or does it charge slower than it drains?

It might be the kernel, I am using a Samsung galaxy S3 usb cable with a usb port car charger and I do not have any problems charging my N4. I am on Baked ROM and Franco kernel.

it has nothing to do with my car chager cuz it was working fine before.

i did not have any problems before using the CM
as soon as i flashed CM10.1, this problem started. i changed back to stock and still same problem

I'm also having problems with charging my Nexus 4 in the car. I have charged my N4 everyday going to work for the last 3 months. But last week it stopped working I'm also running CM 10.1 nightlies since day one if that has any importance.
The car charger works with my old Nexus One
I have bought another car charger that works(verified with N1), but doesn't charge my N4. Both chargers support 1 Ampere.
I can charge my N4 with AC-adapters
I can also charge the N4 connected to my computer using USB.
Any ideas?

bumping this. any solutions? same boat here

I have same isdue, but not all the time. I noticed my N4 stops charging with my car charger, the original charger and the wireless charger when it comes too hot. (after playing a game for example)
The only way I found to make it charges again is waiting for it to get cooler and then replug the charger. I think it might be an hardware security that stops the charge when the battery is too hot because when my N4 has a normal temperature it charges normaly evdn on my 1A car charger

BIG bump here!! My N4 stopped charging in my car randomly around when 4.3 came out....!! Any ideas what's up?!? Annoooying......!
Just in case I drive a 2010 Prius.... Worked fine since the N4 was first released.

[Q] Nexus 7 will not charge

my nexus7 will not charge until it has completely drained....
I am aware of the current battery problems, but mine is a bit different....
Even after going to bootloader and choosing power off my nexus will sit on charge (wall) overnight and be dead in the morning, even though it was at 30% when plugged in....
The only way to charge it seems to be off my laptop. but even then it takes over a full day to charge.
If i hook up to laptop while runing it basically only slows down the drain but still doesn't charge up....
this is very frustrating, and i'm at my ropes end
would dowgrading to an older rom take care of this issue?

No solution, I'm afraid, I'm chiming in to say that I have also been having problems since the same time. For two days, I have been trying different combos of chargers, cables, and outlets, to see if other equipment is the problem. But all of it works fine with my Nexus 4. Mostly, I am experiencing that the unit says "charging" but the battery level is going down instead of up. I managed to get a full charge overnight by using an external battery that I got just for this type of emergency backup. After use, it is back down. This morning, third cable I tried finally seems to be working, for now. In 40 minutes it went from 63% to 65%. I am somewhat relieved but this situation is not normal.
I'm going to start reading through the forum to try some suggestions. I wasn't paying attention to updates. Has this problem been triggered by a recent update?
I understand some suggestions call for letting the battery discharge entirely. It seems that won't be hard to do. I can leave it plugged in and, as happened with most of the cables I tried, the battery level will go down to zero pretty fast. I'm really annoyed, but very happy right now that I splurged on an external battery.

Have you tried a new charging block... That would more that likely be your culprit.

Check your port for bent pins.

I used three different chargers plus the external battery. Two of the chargers have two inputs (i.e., for Apple and non-Apple products). I have five different charging cords, longest is 6 ft and the others much shorter (two are from Monoprice), and one retractable I usually use in the car. I tried every combination I could think of between chargers, cables, input ports, and several different electrical outlets at two locations.
All the various combos functioned fine with my Nexus 4, the other device I have with me. None of them worked with the Nexus 7. All showed as "charging", but they weren't. In some cases, the numbers were going down quote rapidly. Goes without saying, when you're charging, it shouldn't go from 64% to 59%.
The thing that finally worked - with no hiccups - was the external battery. Since everything worked on the Nexus 4, it's quite apparent the problem is the Nexus 7.
Having said that, by this morning, things inexplicably changed for the better. With the device at around 70%, I connected one of the chargers and it functioned normally. Battery filled up within the normal timeframe. I was using it intermittently while charging, as I often do.
I'm glad it's working and very glad I have the external battery that can fill up both the Nexus 4 and Nexus 7 in a pinch. But I still think there's something wrong with the Nexus 7, and I'm not knowledgeable enough to dare try some of the more technical suggestions. Just the term "shorting out the pins" is enough to warn me that I'm not expert enugh to try anything like that. For now it works, I hope it lasts like that until perhaps I can understand the issues a little better.

I'm having the exact same issue as you guys and it has me stumped. On some days it'll work, others it wouldn't. At first I thought I could fix it by rebooting but last night mine just drained all the way down overnight while charging from around 50% and this morning I wasn't having much luck getting it charged using the 2 stock Nexus 7 wall chargers that I have. I'll try using an external that I got recently and hopefully that'll solve the issue for now at least.
Edit: Some people have had luck reversing the polarity on their charging block. I'll give that a go and report back whether it worked for me or not.
Edit/Update: Yup, flipped my brick around so that the big end sticks off the left side and it's at 32% now from 0% after 2.5 hours. You guys might have some luck with this too.

Nexus 7 fails to charge
We have two Nexus 7 in the house, one 11 months the other 6 months old.* The older one stopped charging just before our holiday last month so we took the other. It stopped charging while we were away.* Fortunately my wife had here Samsung Ace [mains] phone charger with her. This worked every time.*
Once home I checked the two Nexus 7 mains units and 2 Nexus 7 usb cables. No combination would charge either Nexus 7.* The Samsung mains charger would always charge both Nexus 7.
Solution:* Suspicious, I ordered an Asus Nexus 7 cradle while we were away. Any combination of Nexus 7 mains unit and usb cable charges both Nexus 7s on the cradle.
Conclusion: The USB socket on the Nexus 7 cannot take repeated insertion and removal of the cable.
Hope this may help somebody.

Yea I had the EXACT same story as you. I had for got to take my nexus 7 charger on holiday but I had my Samsung galaxy ace (s5830i) charger so I used that. when I came back and pluged In my charger It said that It wasn't charging so I used my brothers nexus 7 charger but still no good. It said that my brothers nexus 7 was charging but not mine and than I figured out what I had damaged... My nexus 7 charging port. I had proved this by comparing the the 2 charges and they where very different... Luckly It was still under warranty so I took it to (I cant tell you that). I looked all innocent and pretended I was new to this stuff and they then tried to charge it but no use so they replaced it with a new one but now I know not to put different chargers in my new nexus 7 and that goes to people out there as well

Apparently something is wrong if you see it charging slowly becoming ever since day one, I've felt that it charges really slow!
The only way to test your theory is to downgrade and see what happens. (as far as the upgrade is concerned)
If you have another charger, obviously that would help as well to see if the n4 charger is shot.

When you go to the battery history (from quick settings for example), does it show (constantly or alternating) USB charging when lugged to wall socket? When i had this, i changed my USB charging cable (the charger is ok but the cable died quickly)

Charging slow is usually due to the charger, try another one that is at least 1A output (original charger is 1.2). Nokia ac-10x is perfect and pretty cheap.
Other causes can be bad charging port or sometimes even a battery drain caused by software.

Whenever you plug in the charger make sure that your Phone shows "Charging (AC)" in your battery setting. If it says "Charging (USB)" then unplug and replug it again. Keep doing until it shows "Charging (AC)"...... On USB charging it charges at 500mA which is half the charging speed of AC charging. I had this issue and I am doing the same to charge it quickly. It doesn't take more than 2h 15mins to charge.
