Hey guys,
Been a long time xda member, been busy lately with working in phones for work so haven't had time for here much, but needed to make time for this. I have had an issue with 2 different battery packs to charge my Galaxy note 3 while the screen is off. I have already contacted both companies and neither have heard if this issue b4.
Both will charge the phone up to 1mAh. I have charged my phone in a .7 mAh charger just fine. I am currently using freeza's knox removed rom 2.25b with stock kernel from the rom.
Is fast charge the culprit? Not a huge issue for me at the moment as I use daydream with ultra low setting so it charges fine that way but as soon as I turn the screen off it stops charging.
Anyone have any ideas or run in to this issue themselves?
Donyou happen to have lockscreen security enabled? Password, pattern, etc?
If yes, try setting the lockscreen security to swipe and see if it works.
The reason I'm mentioning this is because the USB connection is turned off when the lockscreen security is enabled and the screen is off.
It doesn't affect a 2.1a charger as that's recognised as a charger, but anything below 2.0 ampere is seen as a USB connection, and not a charging connection. Hence, it doesn't work.

Actually, I already had it on swipe as I like to change the dpi and the screen looks funny at 380 with it always maximizing widgets.
I did try and turn it completely off to test that and same result, with screen off and with the batty packs it won't accept the charge and they turn off, screen on they work fine. Also works fine with a .7 mAh wall charger screen on and off.
I have same problem. I got 2 ports 1amp and 1.5amps but note 3 stops charging after 25 seconds .battery works with other devices. I am sure there is a process that stops it but how do we find it.
got another charger low amps that works, laptop gives 0.5 car usb 0.5 all work except the external battery.

I am trying to figure out why my DroidX will not charge fully all of the sudden. I plugged it in yesterday to a wall charger for about 2 hours when the battery was at 50%, can back after 2hrs, and it was still at 50% even though it showed the charging icon the whole time. I rebooted it, and plggeed it into my computer's USB port, and set the USB option to "Charge only". Came back this morning, after it sat there for 6 hours and same thing - it is just maintaining the current battery level, but not charging it higher.
I have only owned it for a week, and the only change between now and when it was charging properly was that I installed a wireless tethering app, however, that runs on demand, and it has not been open or running. WiFi and GPS are also completely turned off.
Anyone else experienced this? I assume unless I keep it plugged in 24/7 now, it will eventually die all the way down!!
p.s. - I also tried letting it charge while it was completely powered off, but same thing. Shows that it is charging but just maintains current level.

this is not normal ,while in the wall charger it should charge all the way and the same on usb but just slower ,if this problem persist i would bring it to VZW and get a knew batt or phone or both since you have only had it a week
It may not be the phone or the battery. It's probably a faulty DC adapter which is not delivering the proper amperage. I just had this problem with my Slingbox. It would light up but the lights looked dim and I couldn't connect to it. A new adapter fixed it.
(Edit) I just reread your post and noticed you are charging it on your PC's USB port. Try the wall charger or another PC. Some PCs don't put out enough juice to charge.

This is somewhat true. The phone should charge with less power regardless of the source. You notice this most on say a USB hard drive and this is why you have y cables sometimes on the drives that take more power. Does the computer you happen to be charging it on happen to be a Laptop?
FYI - I charge from a desktop PC that has a 1000W corsair powersupply and hig end motherboard.
With that asie though, I was able to get the charging back - works fine after I did a hard reset. Most everything was backed up via Google, so all I had to do was rearrange my icons on home screen and change a few android settings.
I still have all the same apps, so I do not know what caused it. Whatever, it is fine now, but if it happens again I will take it in - I do not want to have to hard reset every few weeks. (I have the $6 a month full protection plan, even if I lose it, it gets replaced)
First off,
this is not about the screen turns on at the moment when the phone is plugged in/out
this is not about i want to keep screen on when the phone is charging
The problem I am experiencing is:
when the phone is charging normally, the screen turns off. But at random intervals, the screen suddenly turns on itself and turns off like when you turn it on just to watch the time and let itself go to sleep. However, I have not moved/touched ANYTHING...
What am i using?
Nexus 4 shipped from play store
stock usb cable shipped with the device
AC adapter manufactured by LG (P500) which I have used for 2 years across P500 and Gnex without problem
AOKP unofficial and franco kernel
Settings are correct
Display settings > Sleep > After 2 mins of inactivity
Daydream > Off
Developer options > Stay awake > Off
Suspecting the ROM?
Unfortunately, I also got this on everything stock, when I was testing the phone before I root and just some basic testing apps were installed (Display Tester, Speedtest.net, Z-device test, Stability test)
BBS and logcat?
Unfortunately during plugged, BBS tells me it has no logs
and I tried to turn on alogcat immediately at the moment the screen turns on itself, however no suspicious logs shown
Only when charging?
Yes, I don't see similar random-screen-on behaviour when it is on battery
I have done numerous searches around but sadly can't find anyone with similar problem... Is it my stock usb cable was faulty which reconnects power at random intervals? Is it android 4.2 feature to screen on when something happens?
Please tell me if you have insights about it or you have experienced before!!! thank you very much in advance
P.S. this is my current list of running apps FYI
Settings
franco.Kernel updater
Whatsapp+
Facebook (refresh interval = never)
Maps (location report = off)
Wechat
Line
Camera360
BetterBatteryStats

Might be a cable problem. I had this with my long cable but had since disappeared after switching cables. Good luck.

I don't think any app that you have running is the problem nor ROM or kernel that you're using. I think the problem is that either your USB cable is nor functioning properly or the charger isn't working properly (which is unlikely since you've mentioned that it had worked fine on previous devices).
If you have spare cable, try that. Also try another charger if that helps.

guys thanks for helping me confirm that the culprit isnt the phone/software
i was then inspired to inspect my AC charger and USB cable and found something totally RIDICULOUS..... -_-
i found out that the line "charged" on the lockscreen blinks for several times at the moment power goes into the phone
then i suspect that the phone is expecting AC power but the initial current is not enough hence making it blink
I took out an non-stock cable and try - similar behaviour
then i plug out my AC adapter from my wall and compare it with the stock N4 adapter... lol my 2-year old LG P500 adapter was 0.7A and our N4 should expect 1.2A as the stock adapter prints... things really get old these days just like the need of changing SIM card
I searched over my home for a universal travel adapter to test out the Stock N4 charger - no blinks of word, no screen on, both cables good
US adapters doesnt fit the power outlets here in HK so tomorrow ima immediately get a 1.2A local AC adapter and everything should be fine :laugh:
thanks very much again guys!
I have a nexus 7 1st generation, the battery drains when it is plugged in so it doesnt charge, however, it does charge when turned off.
I have tried two different wires, I charge using the wall socket.
I have tried using different sockets but I still experience the same problem.
I haven't rooted it or anything
I've been on trouble shooting forums etc and have installed battery moinot widget, its says Status: discharging AC plugged in
Health: good
Temperature: 27°C
Voltage:3907
Capacity: 2854/4325
Battery flow: -612mA ( -14.15%/hr)
I know people usually ask if there are any apps using a lot of battery but right now 77%= screen, 4%= android system, the other is used up by other apps it only using about 2% each
I dont understand what it is because if it was something to do with the connection it wouldnt charge when off, but it does, just not when turned on
Would any factory reset help?
Any advice????
Mine has done that sporadically. With USB and dock. Usually a reconnect will get the current flowing. There's a thread here somewhere suggesting charging on the 500ma computer usb connecting and reconnecting a few times. I think it's the USB daughter board.

OK, can't find original thread. I suspect the battery is too hot and the charge delayed. Then once in deep sleep it never starts the charge. I'm going to set WiFi on while charging, hopeful a sync will wake it to resume charge.

I had the same problem with mine. However, for some reason when i used an HTC charger (with the usb to AC adapter) it was charging faster than losing charge. Once i changed chargers to one with a shorter but thicker cable, i never had the problem again, even with the brightness all the way up.
Hope this helps.
thats the same problem that i got when i first got my nexus 7
what fix it was a different charger and cable
Hi does anyone else have an issue while charging the phone where the display keeps turning on every 10 seconds and then turns itself off?
Bill
No. It sounds like a third party app is causing that.
To check, boot into safe mode and try again.
That happens with one of my wireless chargers. I guess when hits 100% then drops and back to 100% Not sure if your using wireless or not.
I was not on a wireless charger, on the other hand I was on my old HTC changer that I have on another room. Was not doing it from what I noticed with the Samsung charger.
*** tried a different HTC charger and it seems to have stopped turning on, wonder if that HTC charger is throwing out different power

Or maybe it's got a short in it. My car charger was doing this on and off this morning. And I can tell the wires going into the base are going bad.

Yes I have this issue! I just bought this phone a week ago. I've been using the fast charger included with it. Every time I charge with the fast charger, no matter if the phone is on or off, the display will turn on and off every 10 seconds or so like it keeps getting disconnected/reconnected from charging. I tried charging my phone with a regular phone charger and the display no longer turns on and off. What's going on?

Yes, been having this issue as well (happened before I rooted). Only happens when I use my old HTC chargers, doesn't happen with the included Samsung fast charger, or a 3rd party wireless charger. Have tried turning off fast charging in Settings, disabling the Stay Awake when charging option, and charging in Safe Mode - makes no difference. Would be great to know what causes it!
Yes I'm having same issue! Only when I use my old HTC charger! Any other one it doesn't do this! Would love to know a resolution!
Its the older chargers, like the HTC, not having sufficient current for the S7s bigger battery.
Probable solution
I had the same issue with my S7. A week after buying it the display kept lighting up randomly during charging. I switched chargers to an older Huawei and the issue went away. Last week the issue came back. I tried blocking apps but it did not work. What worked for me was clearing the USB cache. Settings > Apps > Show system apps > Enabled > Search for USBsettings > Storage > Clear data and cache. PS - This also works if the phone wont charge due to moisture detection.
I had the same issue with my Samsung S7 Edge while charging using one of my dual monitor's USB Port. I just switched to another USB Port and it stopped doing it.
Weshp, thanks for your very specific answer. It seemed like it was working (my phone stayed off for a longer pause), but after about a minute, it started coming on and off again and when I check, there's data in the USBsettings again. If you have any other ideas, I'd love to know.
My Galaxy S7 has been doing this on and off for a long time. I suspect the cause is overheating because the battery is charging too fast. The lower power chargers won't charge as fast so they won't heat up the battery. If I'm wrong, I'd sure like to know how to fix it.
I can't find the path to clearing the cache so I haven't tried that.
I recently switched using to pro3 from max2. I have a small problem, now i found twice that the phone was completely turned off in the morning.
The charging cable was connected in both cases. I could turn it on by pressing power button few seconds. Than Android boots normally. But normal pressing the button does not turn on screen. I didn't try the fingerprint sensor (forgot)
Also, charging light was off even though the charger was connected. After boot, the charge was 100%
I am using LineageOS 15.1, but I remember seeing a scheduled turn off setting in EUI before switching. Can it be that I forgot the setting on before installing LineageOS. Can that option stick between OS changes? I assumed it should set something in processor to be able to wake phone up from total shutdown?
Were you using the stock charger?
I had issues with a stock charger shutting down the phone overnight I got one good and one bad one. Great phone but the chargers and USB chord are lousy quality. There are a lot of complaints about faulty chargers and USB chord's and lots of replacement recommendations in other Post's

Don"t charge overnight with stock cable.
Although the phone was connected to charger when this happened, I don't understand why you would think that the problem is the charger or cable?
In either case, it happened with 2 different chargers with different cables in different rooms connected to different power outlets. I use the same chargers to charge another Pro3 and also I used them with my old Max2 and nothing like this happened ever with those phones.
Today it happened again and before I restarted the phone I connected it to PC and PC finds the phone as `Qualcomm HS-USB QDLoader 9008` but I am not sure how and why it would go into this mode by itself? Is there a way to debug how phone entered that state?
It's well known that the stock cable can cause various issues, along with burned ports and unexplained shutdowns. The official LeEco forum is gone, but there WERE posts regarding this issue and pictures back in 2016-17.
I guess you weren't on this subforum back in those days, so you missed out on the various warnings. Darkobas and Code suggested that we NOT use them. Users ignored such warnings and as a result their phones stopped functioning properly. This is is very YMMV. Though it's not worth the risk.
You're not the first that has experienced issues, nor are you the last.

@Ace42 Firstly, how will cable cause phone to shut itself down? (actually, as we know now it was in some Qualcomm QDLoader device mode). Can you explain it technically?
I heard about those rumors about cables. To be honest, it feels like somebody was trying to spread FUD. I have bought two max2 phones and four pro3 phones and the cables were perfectly fine. Also a friend of mine bought one max2 and he had no problems either. But I have many cables and chargers because I like to have redundancy and easy access to charger in any room. So I use other cables and chargers. Had no problems with any yet. I am an engineer and monitor the performance of everything I use very carefully. Those cables perform up to specs so far.
Perhaps competitors of LeEco tried to cause panic. Then some people who do not have the necessary information or engineering data blindly suggest something which they can't be blamed for. I have seen it this many times. If you can tell that cable can be used or shouldn't be used, it is 100% safe to tell not use it
Other phones that rely on QC3.0/4.0, such as the LG G6 and Razer phone charge at about half the speed (1800-2100mA). The Pro 3, with the stock charger, will charge well over 3200mA throughout (0-100). It's running out of spec, and not in line with other QC phones.
The Razer, according to owners on XDA, will start over 3000 (until it hits 25%). Once it gets there the rate is effectively cut in half. Again, the Pro 3 will continue to hit 3000-4000 after 25%, and G6 has a constant 1800mA rate. So Samsung and LG phones from the SD82x era shipped phones that charge around 1500-2xxxmA. For some reason the Pro from the same year is much, much faster.
Also if you ask Darkobas (former dev), he'll mention proprietary code for the stock charger. So it's not the same as using Samsung's adaptive charger, or literally any other QC compliant charger. For whatever reason it's able to fry ports (which could be due to cheap parts in the phone), cause the phone to **** off, and initiate QFIL mode.
The last one isn't crazy actually. You can brick an Essential phone by using the stock cable. Now as you mentioned, the phone goes into a special mode (which is unheard of on other devices). That reminds me of these factory cords.
https://www.xda-developers.com/build-your-own-kindle-fire-factory-cable/
https://www.androidauthority.com/essential-phone-usb-c-cable-831817/
What I still don't know is where the problem exists. Is it the phone's board, USB cord, or something else? That's the real mystery.
You raised an interesting point by mentioning competitors. However, I'd rather not take the risk. You're better off using another charger instead of giving yourself a headache.
For the record, before when I most of the time left my phone charged overnight, it would still run fine with stock EUI. Now with custom ROM, this dreaded issue is happening consistently. You won't be able to turn on the phone unless you plug it back and hold the power button for 30 sec or so. And yes I am using the stock charger and cable. No burn in so far since Oct. 2016.

Galactic Stryder and Darkobas worked on supporting the stock charger. It requires additional work.
"Regarding issues with QC 3.0, beware that it has a throttle down mechanism when battery reaches ~40°C it limits input to 2,5Ah and also that it can reach 4,0Ah maximum up to 80% only if the battery temperature is below the threshold for safety zone.
This is the only Kernel using LeEco's charging mechanism with proper safety checks in a minimal manner for ZL1, of course the HW itself can adjust input even without the OEM code in place but it would be a risk to fallback on it without those simple checks.[/QUOTE] - Galactic
Running into this issue too now I'm running aicp, so I guess it's dangerous to use stock charger with these ROMs?

Actually, you are very wrong. Because laws of physics does not allow you to charge li-ion battery with same speed between 0% to 100%. Because the charger can't raise the voltage over 4.35V. Thats why qualcomm always put out figures of 0 to 80% when talking about quick charge. After ~80% charging process will slow down whether you like it or not.
You have spectacularly failed to explain why a cable can technically cause this issue on this phone. I recommend you to first try to understand why something is happening instead of quoting random people's thoughts. There is no guarantee that the people you quote know what they are talking about to begin with....

No reason to be worried, stock charger has nothing to do with this issue. Also stock charger works perfectly fine. @Ace42 simply does not know what he is talking about. Spreading FUD, you know?
Actually, in my device I even limited maximum charge voltage to 4.2V (only charge up till 84%) and it still turns itself off sometimes when connected to charger, even when the phone stops charging, also with different chargers and cables. Even with USB-PD chargers with type-c outputs and type-c to type-c cables. This clearly tells me that the issue is nothing to do with charger or charging voltages or charging speed, or cable. Also here it was mentioned that this did not exist with EUI and somebody who used LOS 14 says he didn't have it until he upgraded -> https://forum.xda-developers.com/le-pro3/help/los-15-1-zl1-leeco-pro-3-x720-shutting-t3846441

thats me who was mentioned upgrading from LOS 14.1. I have a detailed description of my issue in the thread that was linked above.
never had any problems with the stock charger. And my phone turns off when i am not using it for several hours, unrelated to it charging or not.
seems to be related to deep sleep I guess?
I have exactly the same problem. The phone turns off twice a week twice a week. An alarm does not work. Daughter is late to work .
