Screen acting weird when charging - Nexus 5 Q&A, Help & Troubleshooting

It like its lagging with typing. Skips around and kind of has a mind of its own. Only when charging...I don't recall having this issue with my last phone.. This is my new RMA. Franco and cat.

From my understanding you're using a custom ROM and kernel (" Franco and cat"). Did you mess with the CPU speed or something? It could be a bad flash. This question probably would be better suited in the " Franco or Cat" post. Maybe someone else had the same issue and they found a workaround.

Don't know of this will be relevant but I've had this problem on other phones. It turned out to be cheap chargers and cables. My desire HD did it, problem went away when using the OEM charger.
Hope this helps.

Sometimes thermal throttling can make the device lag whilst charging. I've seen this here a few times

I've seen this happen on a Nexus 4 when the AC charger couldn't provide enough amps. Check the usb and wall adapter.

Me too used to have that problem with my nexus 4 and a samsung 2.0 amp charger , it is supposed to be the original, anyway , the problem fade away once i start using the OEM charger shipped with the nexus 4 1.2 amp

Just and FYI on this.
Chargers are supposed to be polarity free for the wall outlet and this is why they have two skinny plugs and not one skinny and one fat.
Flip the charger around. I have seen this on several phones and in several forums that once you flip the charger around on the wall outlet it works fine.
Cheap chips inside can be affected by the AC current and some manufactures screwed up on their diode placement so power was only applied for half a second lol. So your phone fips out thinking that it is charging then not charging. gotta love technology.
This is not always the case as some people had faulty chargers period but this issue has been reported and found to be, most of the time, a polarity issue with the wall outlet.

Last but no least a bad power source can really screw with you. Whether its the wall or a bad charger or dirty power can really screw with sensitive equipment. Pretty much goes with what red dragon was saying.

[Q] When charging G2X the touchscreen doesn't react properly to my fingers

People on here suck ass at titling threads properly, thus making finding relevant topics a pain in my ****. I hate you people who type "HURR DURR MY PHONES BROKE".
Anyways, whenever I have my G2X (P999DW) on a charger, whether USB or wall, the touchscreen doesn't follow a constant finger press and dragging for very long. It will dodge off in random directions at random times. Needless to say, this makes typing or even unlocking my phone a rather tedious process.
I was wondering if this was a known issue or not. At first I thought it was because I had before ran CM7 with the Trinity 1.5ghz kernel from DerKernel.com
I had tried running mine at 1.5ghz, but it wouldn't take. I managed to run it at 1.2ghz with a slight overvolt, and it ran stable.
Well, I've recently been forced to reinstall a new Android version on it, and went with a MIUI variant, and decided to run it only at the stock 1.0ghz now, but it's still being wonky when I plug it in to charge it.
Gingerbread 2.3.7 MIUI on it now. CM7 before. It never did this with the stock rom, I could play games on it for hours when it was plugged into my laptop.
Are you charging it with the original USB Cable?

Indeed, the cable that came in the box. It's got a sexy matte finish that I like. :/

I had this problem when I was using a different charger, but I'm not sure why this would happen on the original. It was very strange indeed... Maybe just try a different charger and see if you have the same problem.
My G2X did that with almost all chargers except the original LG charger and a BlackBerry charger. My Atrix 2 does it with all chargers, including the included Moto charger.
My old iphone did this with a really cheap charger.
I'd just try another cable.

It's RF interference disrupting the display hardware. A different charger or cable might help. Otherwise you might try for a warranty replacement.

A100not recognizing battery??

I have an A100 that was given to me by a friend. It works fine when plugged into the charger. It says "battery status unknown" in system settings and when I unplug it it dies of course. My friend says that their dog chewed the charger cord so they put it away in the closet for about a hear and recently bought a new charger. This issue has been a problem ever sense. I'm thinking that the charging circuit may have been fried. I'm not sure however if the charging circuit is built into the battery or the main board. I can order a battery for around $50 but I don't want to spend it if it isn't going to fix the issue. I tried to OTA to ICS but it won't start the install without a battery charge at least 30%. I plan on breaking out my trusty multi-meter later today and testing some voltages at teatbpoints in the mainboard. Any other ideas? Has anyone else experienced this issue??

My A100 does the same thing. It started after I replaced the LCD. I replaced the battery with one from eBay, but it made no difference. The charge may have run down while I was waiting on the LCD, but I don't know for. As far the eBay battery, who knows about that. It could be charging circuit, since two batteries did the same thing. But, now that I think about it, the original showed 3% charge for a while which enabled me to move to another spot and plug it back in.

Wish I could get ahold of a circuit schematic for this thing.....I would construct another charging circuit.

Mine did that a while ago, when still under warranty. Sent to Acer, they fixed that charging circuit. Apparently a common problem. I suspect a regulator chip, but it's a guess.

You could honestly just charge the battery sepretly, and I bet it'd work. You could even, if you're talented enough, strap a bigger battery to it and be able to use it for days.
Sent from my SPH-L710 using XDA Premium 4 mobile app
With my A100 not even recognizing that the battery is plugged in, I doubt charging it separately would make a difference. I just want it to "think" the battery is there and charged to at least 30% so I can apply a few OTA updates and acquire root. I don't mind having to use it while on AC power only. I have a Galaxy Tab 2 that I can carry around.

Slow on charging

Hi,
is anyone elses Nexus 5 becoming kind of slow when it is connected to the charger? I mean it doesnt feel snappy in the menus like there is an input delay.
is this normal behaviour?
Sent from my Nexus 5 using xda app-developers app
Are you charging it using an AC wall outlet or via USB on a computer? It will charge slower on USB but if plugged into a wall, should charge rather fast.
If it's not seeming snappy, perhaps try a restart first and see if that affects anything.
its on both, AC and USB and i am not referring to the speed of charging rather then to the speed of the phone.
It was on Stock and now it is on Catalysm with Franco too.
If i unplug it everything is back to normal.
A reboot doesnt fix it
Sent from my Nexus 5 using xda app-developers app
I would venture a guess that your kernel settings have messed it up. Roll back to stock and see if it resolves itself.
do you think just a flash of the stock kernel resetts those settings? i have had this Problem with the stock Rom too. (cant say how it was before unlocking and rooting, did that right away)
edit: after a bit of searching i found similar threads but on other phones.
they say it could be because of interferences from the cable with the digitizer.. ill try another charger and then flashing back to the stock kernel

Hey guys,
I just wanted to bump up this thread and see if this is a common issue or not. My Nexus 5 becomes really unresponsive and choppy while charging, especially when scrolling or pinch-zooming. I've tried different chargers (from other manufacturers because I don't have a second "original" Nexus 5 charger) as well as different sockets but it happens everytime - sometimes it's less noticeable but it's never the phone never feels as responsive as it should or as it feels while unplugged.
I've also made a little video demonstrating the problem: https://dl.dropboxusercontent.com/u/74551292/nexus5_slow_while_charging.mp4
I also read threads about this issue happening on other devices with hints to the charger being the source of error. Because of my tests with other chargers I'm not so sure. Although all of my other chargers do have a lower output (maximum of 1A) instead of the original charger's 1.2A.
So what do you guys think?

Does anybody use wireless charging

I have never tried it. Is it worth paying 20-40 bucks for a pad? How fast is it?

bought a Nokia DT-601. was that impressed have since bought another.
Its not going to change your life but it saves fiddling with connectors every time. charging time is quick (even from just a USB feed) and it gets warm, but not hot !
if you have the cash to spare then give it a go Ive wasted similar amounts on numberous replacement cables along the way to be honest.
I use it all the time. Sure beats messing around with USB cables. Its not as fast as plugging it in, but its worth it

I love wireless charging. It's just no hassle, and since I'm kind off paranoid of breaking the micro USB port on my N5 because it's really tight, it works. It's not as fast as the plug in charger that came with the phone due to the inherent inefficiencies or wireless charging, but it's still pretty quick. Depending on how low your battery is when you start charging, it would probably take 30-60min longer. But, I'm never really in a rush, and always keep my battery topped off, so I'm never in dire need for a super fast charge.
A word of caution though: STAY AWAY FROM THE TYLT VU. It has a serious issue with sporadically overheating your device. Check out these threads:

Do it! Worth every penny! It’s elegant and I always have plenty of battery life when I’m on the go because of it! OH, AND THE IPHONE CAN’T DO THIS!
I don't think I ever even opened the USB cable that came with it. I use a Nokia DT900 and it works great.

just noticed the thread in general. did a reading and decided to buy the nexus 4 official wireless charger. For me its the fact that I do go through a lot of extra cables in a year and it would be nice to preserve the port. But most importantly. Smoke em if you got em.

I use a wireless pad on the bedside table. Just drop my phone on it at night. Works a treat. Thinking about getting another one for my desk at work.
I use it at work. Love it.

Good choice. I returned my two Tylt Vu chargers for an N4 Orb charger I use at home. It's build quality is solid. I also use a Nokia DT-900 at work that works flawlessly as well.

Yeah I got the 910. I read regularly here about people having overcharging issues on non official chargers. The Nokias were consistantly reported as good though

I mainly use the google official one and let me tell you- wireless charging is so worth it. Of course if you took a stopwatch and figured out how much time it saved as opposed to plugging it in, you wouldn't be saving much time- but there's something subconsciously... awesome about it. Plus with the quick charge 2.0 or whatever its called that our phone has- epic charging speeds. Worth every penny imo. I'm considering getting a few portable QI chargers as well to replace micro usb power banks.
Yup. Sod it's benefits... Its just seriously cool every time you do it

No Wireless Charging...

So randomly wireless charging just stopped working yesterday. Anything i should look for that might lead me to the reason why? Any way that i can test the charger with a multimeter to see if it working?
thanks guys!!
Are you using the genuine wireless charger from Google?

I had this type of problem and found it was caused by overheating. Took my device off the charger and let it cool down then tried again and it worked. After experiencing this issue randomly I gave up on wireless charging and went back to the original USB charger. It is faster and has no overheat issues. Too bad as I really liked wireless charging but inconsistencies and concerns over device damage has led me to abandon that adventure.

What charger did you use? I'm using the Nokia one (DT-900) and I haven't had any issues for 1.5 years. It worked with the Lumia 920, somewhat with the N4, and great with the N5.
