Nexus 4 / Energizer Qi single-slot charger - Nexus 4 Q&A, Help & Troubleshooting

So I just received my charger and laid the nexus on it. Everything seemed to be going fine, until I received a text notification. At this point, the phone stopped charging and the blue light on the charger started flashing. After I removed the phone from the charger, the light still flashes until I unplug it.
Anyone seen this?

Yeah, mine seems to do this on a random basis. It'll be charging fine, and then it will go into this rapid blue flashing state and the only thing you can do is power cycle the charger and try again.

I had totally forgotten that I had posted this... I haven't had this issue since the first day with the charger. It's worked just fine ever since. Not sure what the issue was, but it seems to be gone.

Weird charging problems

On a few occasions now I have plugged it in to charge overnight, to find that it has not charged, or only part charged. The LED starts blinking as it should, but the next morning it is still blinking and only gone up, say 10%.
Also on occasion, I plug it in to charge and although the LED blinks, the battery icon does not change to reflect that it is now charging.
Has anyone else had similar problems or, as I suspect, do I have a defective unit?
I have only charged and walked away from my device once (that I can remember) and for whatever reason it either failed to charge or was just charging stupidly slow. I ended up unplugging booting the device and plugging it back in again where it proceeded to charge normally.
Not sure if this is similar to what you describe but it is a strange behaviour while charging even if I have only come across it once so far.
Well, there's not much chance of getting a replacement any time soon, so I will just cross my fingers that it needs "running in". Will try rebooting also.
Thanks.
There are reports of this issue happening, indeed its just happened to me!
Youre not alone and afaik its not a defective device. If i find more info ill let you know

I can only charge mine effectively if I turn the Vega off, if not if charges for a while but then the light just goes out. If the Vega is off it charges fine.
There has been a lot of talk about the sub-standard chargers over at MoDaCo, I keep meaning to try and get a new regulated charger from somewhere and try that.
Maybe this weekend.

Well spotted, now I turn it off before plugging it in, it works fine.
Another annoyance is my screen brightness reverting to default after every boot. I have to go into settings and although the adjustment bar is at max, have to re-set it to max for it to apply. Anyone else?!

Hashcode's 3.0 kernel Charging Observations

disclaimer: Please delete this post if there is something like this here or somewhere else in Kindle Fire General already (and feel free to move this or re-post it somewhere else)- I have looked but haven't found anything like this yet so...
I have seen a few posts about the charging issues and feel like doing something productive here in the 'General' (non-dev) section of the Kindle Fire that may hopefully help many people using Hashcode's awesome kernel. I am running the new AOSP jelly bean rom by hashcode (using the same 3.0 kernel used by many) and have figured out the behavior almost completely in regards to charging on my device so I am going to post what I have observed in the hopes to help out others and maybe sway those 'on the fence' that aren't wanting to unlock the full potential of their device because of this 'issue'.
I recommend always using the wall charger that came with your KF. Some of the threads where people are having actual charging issues they are attempting to charge through usb. I once owned a Dell Streak 7 where usb charging was disabled (charging light would come on but it would not charge) by Dell since there wasn't enough current to adequately charge the device. So ALWAYS (whenever possible) use the included charger!
I have never yet had any issue getting my KF to charge when plugging it in when it was TURNED OFF. Plugging it in immediately turns the device on and once it starts booting up the led indicator turns from green to orange and is confirmed to be charging when accessing settings->battery.
Twice since I have flashed the JB rom I have plugged in the charger while it was on (and waited about 30 seconds) and on my KF in the settings-> battery still showed "discharging". So here's my methods when observing various charging situations (and it's really simple) of ensuring the charger will work properly.
My device's charging indicator appears to work properly but is only on when the display is on (orange when charging, green when battery level is 95-99%, off when fully charged).
An oddity I have noticed (and also read somewhere else) is that the charging indicator orange led light has a tendency to turn on (and stay on) and confirm charging much more often when the display is on so I always have the screen on when plugging it in. It's still possible to start charging with the screen off and everyone's device will behave differently. I am not trying to discourage anyone from charging with the screen off. Again this is what I have noticed in regards to my device.
Make sure that the display is on when you plug in and if the led comes on then you're good. If not, sometimes it is delayed so wait 5 seconds or so. Sometimes you need to cycle the screen on and off once or twice and the led will come on. Always confirm in settings -> battery.
If you ever plug it in and have the led come on and it immediately turns off (this is the behavior where I have experienced issues) check in the settings-> battery and if it says 'discharging' wait 5-10 seconds. Hit the refresh button. Try cycling the screen on and off once or twice. If it still shows 'discharging' then unplug the charger. Start over from the beginning (this has happened to me twice).
That's about it. So if you are on the fence and aren't sure if you should flash any ICS/JB rom only due to concerns regarding charging... please do yourself a favor and take the plunge-the performance is incredible. Hashcode and other devs here have poured out their time and efforts to make our Kindle Fires AMAZING. If you like their work and efforts hit the 'thanks':good: button. If you LOVE your dev's rom and can't imagine living without it hit the 'donate' button so you won't have to worry about living without it.:highfive:
If anyone else has any additional observations please add them to this thread- it will be very helpful for others!
Great post, thanks OP. I had the same exact problems with charging. That said, the problem seems to have gone away now that I just flashed the [CM10] Jelly Bean ROM that @twa_priv posted. With this one, Google Now works (albeit without voice search), and I'm seeing the amber indicator even when the screen's turned off.
Fantastic work by @twa_priv, and many thanks to @Hashcode!
Edit: Scratch my last. Back to keeping the screen on. It was going well for a while until the amber light decided to go off. Ah well, guess we'll have to wait a bit longer!
Great post! Mine charges regardless of both the state of the LED indicator and battery status under settings. I plug mine in every night, the LED blinks orange, goes off with the screen, and the device is charged at 100% the following morning every time. It also charges even if the status is listed as discharging, and on mine it will be listed as discharging the entire time it is plugged in. It should also be noted that mine charges just fine, albeit rather slowly, via USB.
may i just add that if you have a battery monitor widget, like Battery Life, from the play store, most have a little charge icon that shows up when the device is charging, this has worked for me ever since hash first made his kernel and it was all buggy.
hope this helps someone.

Same for me.
After I installed jelly bean, I started having charging issues. I would leave the kindle charging on the stock charger all night and it wasn't even at ninety percent. I then noticed that I could not connect the kindle top my computer, PC or Mac, not adb not usb mount, nothing. I even loaded Ubuntu on a stick and it was not recognized. I thought maybe it was a kernel problem so I went back to Modaco and I still had all the same problems.
Coincidentally, the same day I had left the kindle in my car. Maybe the heat fried something. Just in case I thought I would post in case this happened to someone else. I don't think a kernel could fry hardware across roms.

My two cents:
I'm running Jandycane 1.4 (by lithium), and I'm using a charger that came with an old Moto Droid. There is no LED indicator showing anything, nor does the tablet itself have a charging symbol showing in the task bar (no lightning bolt, doesn't say "charging" or anything).
Regardless of everything, the device simply charges when it's plugged in. Every morning, I wake up to a charged KF, ready to go

Back and forth from charged to charging

Hey guys, just started seeing some odd behavior today. My phone is currently 73% charged and when I went to top it off I noticed the LED was flashing strangely. Turning the screen on and checking the lockscreen I noticed that it was constantly going from Charged to Charging, back and forth. It didn't seem to actually be charging at all.
I tried two different adapters and cables then a cold boot. It started charging normally for a few minutes, then started doing this again. Does that sound like a bad USB connection on the phone's end?

Sounds like a dodgy battery to me.
Does it show the same behaviour when you plug it in with the phone turned off? If not, then it could be the ROM you are running, especially if you have dirty flashed different ROMS.
If its the battery, you can get replacements or just send the phone back. Try running it right down too and fully recharging. I had a similar problem on my Sensation and it turned out to be the battery. There are threads on how to remove the back cover and replace the battery. But avoid opening it unless you have no recourse with Google / your supplier.

Thanks, I'll let it run down today. I am running AOKP but haven't flashed anything recently and this just started today.

A better test would be to see what it does when its turned off and charging. If its staying fully charged, then its 99% software issue. But batteries can be shyte. Esp if yours is an early model which the batteries are about 7-8 months old now.
Hope you narrow it down m8
This is a really stupid question, but what SHOULD happen when it's turned off and plugged in? I've never had it off before since getting it.
Plugged into charger #1: Charging icon with lightning bolt briefly, screen off, then icon of battery filling up, screen off. Screen kept going on and off.
Plugged into charger #2: Charging icon with lightning bolt briefly, screen off, then icon of battery filling up, screen off and has been off since.
It did charge to 100% (while turned on) on charger #2 last night, but I've also seen it do the Charged/Discharging dance on this charger once as well.

Charging intermittently stops and resumes rapidly

My 6P on 6.0.1 stock with the march update has had occasional times where it will intermittently charge, then stop, then charge endlessly, changing back and forth about once a second or more often. There's been times I've woken up, like today overnight when I noticed it barely inched up a percent or two on the Google USB-C cable connected to my laptop.
To isolate this from being a defective cable issue, this has also happened with the Google charger that came with the phone. I would see the screen turn on in fact, like when you first plug the phone with the screen off, to indicate charging has begun. That would occur every few seconds.
I'm a little concerned. The time it happened with the charger, a reboot seemed to have calmed it down. But today no matter the restart, the charging just keeps cycling nonstop.
Anyone else had this? Would it be wise to file a problem with the Google forums and contact support?
Thanks for any help!
Same problem here
Dang, good to know I'm not alone!
I've also experienced higher battery drain (twice more I'd say) than normal recently. Even overnight when I used to see hourly drain rates of 0.5%, now I see 1.5% and higher. Getting worried the charging issue may be damaging the battery. But it could also be the patch or a rogue app.
I have the same issue - it started about 3 days ago
Well either the cords bad, the brick is bad, or the receptacle. Or the charging port on the phone, the battery or power control module in the phone. Or if theirs a thick case on your phone.
Sounds like it starts to charge then stops. But I'm no electrician. Oh wait, yes I am.
It starts to charge, then stops as though the cable was disconnected, then resumes within half a second, then disconnects, and so on and so forth non stop.
Case might be a reason. It's a rubber and plastic transparent Spigen one. I'll try removing it when it happens again next time.
But at this rate, sounds like 3 people are having the same issue, and if it's a hardware one, then damn....
This isn't the charger... There is something buggy with the update. I woke up a few days ago after the march update with an almost dead phone, and the charging icon flashing over the battery, as if the phone new it was plugged in but refused to charge. I unplugged and plugged it back in with the same result. I restarted and tried again, same result. I was only able to get it to charge my plugging it into my girlfriend's nexus 5x charger, which instantly started charging my phone. I went back to my charger and all of the sudden no issue and the phone was charging fine. There is definitely something up with this update.
Well then, that makes 4 people now.
What's a good way to report this?
I'm not seeing the same exact issue as you guys, but I AM having charging issues after updating to MHC19I. I can still charge my phone from the stock charger and my other USB-C chargers, but now none of them allow my phone to charge rapidly. Do you guys who can get your devices to charge from a rapid charge compatible charger see the "Charging Rapidly" message on the lock screen? Ever since this recent update, I've noticed that my device isn't (and is taking over 2 hours to charge fully from ~20%).
I have this problem too. It's fixed by a reboot so I'm assuming it's not a hardware problem. It only happens once a week or so.
The first time it happened I didn't notice the charging/not charging and only realised something weird had happened because my phone was off & showing fully charged. My phone is never switched off.
I figured it out the next time when I noticed the screen was still on during the night. Switching from charging to not charging was keeping the screen on.
So glad it's not just me.

I normally see it say that on the USB C charger. That being said, you seem to have an intermediate speed going on, as opposed to super slow normal USB cable speeds and the USB-C fast charger. In my experience most 1-1.5V low amp ports like my Mac's, or the car's USB port will charge at a rate of about 1% per 3-5 minutes. So a full charge would take 8-9 hours from 0%. From the USB-C wall charger it would be about 1%/m so an hour and forty is enough to get it back to full.
Based on that your charger seems to be somewhere in the middle.
But yes it isn't normal. If you are using Google's native hardware, you should see the same charging speed as I am.
I'm just terribly worried this cycling is destroying my battery. I have definitely not gotten the same battery life the last few weeks.
Hey guys!
I experience sort of the same problem as you guys, but i have the Nexus 5x
i copy from my thread at google nexus forum
My phone just randomly die. It will work for like 2 hours. Almost like the battery would been disconnected.
When the phone shutdowns it says the battery is low and try to charge. The Battery icon with a flash is showing, but just for 5-7 seconds, then it shutdown again and it's looping again and again and again.... To get out of the loop i'm booting in to fast boot, then push at start. and it is almost 50/50 if it is working. It can be booting up and you see the red/yellow/green/blue yada yada boot-up sequence then in 5-7 seconds in to the sequence it would shutdown again immediately.
I tried several factory-resets. re-flashed to stock. Nothing helps.

Same issue
Just starting having this issue. It constantly says charging then a second later shows no charging and the process keeps repeating itself. I did a reset and the issue seems to be resolved for now. Really hope this isn't a constant issue. Definitely appears to be software related though.

I hadn't had it for a while then recently it happened again once. I still don't know what triggers it for sure.
The battery drain is also rather random. There are days I can expect the unit to idle and drain at or below 2%/h, but lately it just goes through it way faster, twice that. I am unsure why and how that happens so randomly. Seems the Google Play Services and Google Apps are using up some %s. Not much else I can identify.
I've had this issue since a few days ago, restarted the phone and it's come right for now.
Haven't experienced this in weeks now.
Seems largely gone.
Any updates on this? My Nexus 6P started showing the same symptoms (either won't charge at all, or charging cycles on and off rapidly (< 1 second) and only sometimes charges). The issue appeared out of the blue 4-5 days ago, just before the 1 year anniversary of receiving the phone. I tried different cables and adapters, still no change. Last night at 11pm it was at 50% when I set it to charge and it seemed to charge. This morning at 6:30 am it had only charged up to 83% and was charging on and off. Worried about how to reliably use the phone if it won't charge, and also how this might affect the battery / other circuitry.
Any help/tips appreciated!
Edit: The phone hasn't been dropped or had any other issue that may affect the hardware. Also, no OS update or anything recently (AFAIK - it did not ask me to install anything, not sure if there were any silent updates). It is currently on Android 7.0 Nougat (baseband version angler-03.72, build NBD90X, security patch level Oct 5, 2016).
Have not had this in a long time. It sort of stopped on its own. :S
Solved (for me anyways)
I just had to restart the device.
I'm having the same issue on my LG G5. Started out of the blue and like others, restarting temporarily solves the problem. Anyone solve this yet?

Nexus 6P Died while charging, Red notification light blinking

I am new to XDA and not sure where to post this but I bought a refurbished 32gb Nexus 6P off of Amazon. I received the phone on April 20th and it didn't come with the OEM charger. The charger worked fine for me. Last night I was using my phone and noticed it was at 15% so I put it on the charger and user it for a little bit longer. I check the battery percentage and I noticed that it was losing charge still and under the settings, it said: "Not charging". I decided to put it away for the night thinking that would help it charge. I wake up and unplug my phone to use it and notice that the screen didn't come on when I tried unlocking it. I try powering it on and the notification light blinks red once. I plug it in and the light keeps blinking. I don't have any other charger and I have tried multiple power sources and hard resetting it but it won't even show the boot loader. And the seller does provide a 90 day warranty but I wanted to see if I can fix it without sending it back as it is my only phone and I get my work schedule on it. ANY HELP WOULD BE GREAT! UPDATE IT FINALLY BOOTED UP
how did you get it to work?
