ATT Note4 Fast Charging not working after lollipop update - Galaxy Note 4 Q&A, Help & Troubleshooting

Hello
After updating the phone to lollipop, the fast charging feature is not working.
It says "Fast charger connected, Use Fast charging". Tried it with two genuine samsung note 4 chargers/cables
The install went fine. cleaned Cache after install.
Any ideas please

I think there is an issue with Lollipop
So, I did some experimentation.
1. I did a factory reset of the phone, tried again. FAST Charging still does not work.
2. Then I downgraded the phone, to 4.4.4 , Fast Charging Works
Not sure what the issue is , definitely there is something going on

Upgrade it, take it to a service center and let them find out whats wrong They might even replace your phone or charger

Samsung Service center :9

Took it to a Samsung Service center, the rep checked the phone...re-flashed the phone and said that the phone charging is fast enough (it went to 75 o 78% in 4 minutes was the explanation)...Tried explaining that Fast charging (0 to 50% in 30 minutes) is not working...but he would not understand

Samsung focus will not recharge?

So.. I have been spending more time with my hd desire.... but I had some major issues with my new focus. It froze on me once or twice (windows ) and it randomly restarted.... but the most troubling aspect is it is not charging.... the first day I had it... I left it on the usb cord... the ENTIRE night.... it did not charge at all?!!
So last night, I did a reset and tried a wall charge... nothing... then I did a FULL format/hard reset and back into the wall overnight.... now it is at 40%
what gives? I know no phone could take 28 hours to charge? Any ideas or suggestions would be greatly appreciated... I tried the battery pull, restarting etc
thx
update: I called samsung and they said take it in to my carrier, they will send it out? Rogers does not know anything about these phones yet?
Return the phone and get a new replacement while you can. Obviously a hardware defect. If you wait past 30 days, you will have to settle with refurbs for your warranty replacement.
I bought it from Ontario but I live in Winnipeg, they said I had to bring it back to the orignal store for replacement... and there are no focus here.... pretty lame so far!
hahaha, rogers says I did not buy it from them.... the imei # does not match, so I have to go through samsung, samsung says they do NOT repair or exchange phones and I have to go through rogers or the store of purchse.... which is not possible, cheaper to buy another phone then fly to ontario
samsung is crap, never again.
If you did actually buy it from a Rogers store and you have a receipt to prove it, then you can contact customer service and speak to a supervisor. They will arrange for you to ship it to them and they will ship you back a new unit.
So, for all of you that has a normal working phone... any freezes/issues? I am guessing all my problems were from some hardware issue
I liked typing on the phone....

I had this exact problem with my phone the first few days I had it.. let it charge over night and it still showed an empty battery and gave me the warning beep every few minutes.. i was about to take it back to the store to replace it when i came across a set of instructions for entering diagnostic mode and listing the battery details (sorry i forget the exact sequence of keys but you should find it on here). All of the battery details were 0 or none which confirmed there was an issue.. after exiting this diagnostic mode the battery started registering correctly.. no problems since..

Bad USB Cable?
I wonder if it was just a bad USB cable?
Charging the phone by USB to PC is CRAP! I tried to charge it that way over an afternoon, and the charge meter barely moved. Switched to using the wall plug, and the battery charged fairly quickly.
D
I tried the wall charger for 12 hours..... tried it all.... thx
Sent from my Desire HD using XDA App
update: I went to lunch with a friend... he was late, so I went into a rogers plus store... she had 1 in stock... so I bought it, brand new, sealed $671.... yesterday I did my best to kill the phone, now... 3 hours later the phone is not charging at all and I had to pull the battery, just like my used one.... so now, after the battery pull and being plugged into the wall charger... it just has the battery symbol with the plug on it.....
If I can get into the phone, i will try the dianostic thing, but seriously? wtf, but now I have the receipt... and a 15 day return policy.... but come on, I just want a windows 7 phone that works?
did the battery thing.... lots going on over the 3 pages... not sure what I was looking for... although, I seen the battery go from 1 to 2... maybe it is charging now.... will update soon, but this is pretty weird for a brand new phone?
** did a soft reset, battery pull... charged for awhile... still not moving, I go into the battery thing again... now it says 10%.... so I get out of there and see some battery charge.... but it has been on there for awhile and has not moved... so I go back in, now it says 29%.... screwy stuff, I will see what it says after being on the wall charger all night.

phone won't charge

Hello,
My sgs won't charge anymore
My battery went down a few hours ago, so as usual I connected my phone to the wall charger. after an hour when I went out cycling I took my phone with me and realized my battery level went even lower then before I charged it.
I thought that maybe the charger wasn't connected properly (something that happened a few times before) so I wasn't nervous.
When I came back and reconnected the phone to the charger and made sure the charger is connected properly I realized the phone isn't charging at all.
The battery level do not increase, and the phone gets hotter and hotter every second.
I tried with two original samsung chargers. same problem.
After a few minutes the battery died. When I connected the charger again when phone is off the battery animation did show up but with a weird yellow triangle (like the one on boot when using non stock kernel) next to it.
Then I tried to charge it using the USB cable, which did something as I could enter the recovery and do a complete wipe right after backing up everything. But, it doesn't change anything.
SO.. after the long story (soz) doe's anyone knows something about this problem? is there something I can do?

A search will find the same question asked ...
Answer = service centre .
But before that put a stock rom on a clean phone to remove root and set rom counter to zero and test battery charge .

i have alredy replyed that but usually the problem is diferente kernel installed or rom installed, try to update kernel for an updated version.
to do that check the tread here.

Phone wont charge anymore!

So my SGS4 phone wont charge anymore!
- I went out on Sunday, and later came back home at night. I plugged in the phone and went to sleep.
The next day came over (Monday), in which my phone had full power and battery started draining for normal reasons. During the daytime, at one time, I noticed in the status bar, it said "T-mobile update" , I immediately lowered the status bar, but it was gone. Weird, I thought to myself as I didn't click any "yes" or "ok's", which I wouldn't press anyways. So the night came and I went to charge my phone to realize that it wont charge at all!!!
I tried:
- 3 different charges
- Charge by connecting it to PC (phone is not even detected)
- Let it plugged in all night powered off... woke up, still 2% batt. (Didn't charge)
I don't know what to do.
I might have to send it back to T-Mobile.
Info about my phone:
Rooted CF Autoroot.
No ROMs (Stock)

Have you tried turning it off and charge? See if the adapter pins are not broken on the phone?

I'm sending the phone back to T-mobile.
My phone is rooted with CF-Autoroot (for the 9505).
Will I need to unroot, or change firmware????
Send it back. Unroot if you can.
where can I find the original firmware, or un-rooting way?
charge
Do you have another device to charge the battery? I wouldn't recommend trying to unroot your device without a battery with already 50%charge. Also, have you tried doing a battery pull for a few minutes to see if it will charge? I'd try doing a data wipe and factory reset before trying to unroot. You can find the stock firmware in the Android development forum. . just make sure to use the stock firmware instead of the prerooted firmware. I just worry that if you try to do a warranty claim, ttmobile might blame it on custom firmware and deny the claim... probably wouldn't happen but I'm overly cautious.
Try usb
After two monts, my S4 just stopped charging. Woke up one morning and saw that while plugged in all night, battery was at 40%, lower than when i plugged it in. I had been using a couple of old chargers and a dock...all had previously been working for a fairly speedy charge
So, plugging into a wall charger will not even get an acknowledgement from my phone, however, plugging into a turned on and charging laptop via USB will charge my phone. It takes longer to charge but works.
I am rooted and do not want to unroot and take my phone back to ATT unless i really have to. Hope to find a wall charger solution. Even the charger that came with the S4 is useless in the wall.

[Help] Moto X Play won't show it is charging but the battery is working properly.

So, 2 days ago I was charging my device (XT - 1562 Indian Version 16GB) and when I saw the phone after 2 hours the battery was still at 15%... so I got into the battery options to check if the battery was charging and it was showing "Not charging"(SS attached) so I rebooted my phone and it was still showing not charging, I also did a factory reset and still the problem was not solved so I booted into the fastboot mode and there it was showing that the battery is charging. I was confused so I thought that there may be a firmware problem(6.0), so I downloaded factory images of 6.0.1 and flashed them(the BL was locked) and still the problem was there then I unlocked the BL and flashed 5.1.1 and problem still persists. Guys pls help me. :crying:
Also please tell me how can I flash 6.0.1 again via Fastboot mode. I am still at stock 5.1.1
Edit : Update : Now I have installed a custom ROM (CM 13.1 by Temasek) and now the phone is charging like it should but it charges till 82~85% and then stops charging. Cant give the phone to the service center because I unlocked the BL.

Thanks for the reply bro. I have updated the thread so can you tell me what is the problem.
are you using the original charger and cable ?? charge the Device when it's off then turn onforum.xda-developers.com/showthread.php?t=1782420
I'm having this exact same problem on my xt1575. I bought it from a nice dude on Swappa, but he seemed pretty green concerning phones in general. He rooted/unlocked it, then appears that he kept the stock ROM while flashing the franken kernel. I didn't notice this for the first day or two as I opened it and poked around for some signs of something loose/water damage: nothing.
I couldn't sleep last night, so all morning I've been doing what I can to play around with clearing caches, flashing different ROMs, and anything else I can find in the software side, but aside from somehow getting it to get past the previous cap of 4% to a whopping 25% before slamming down to 11% (percentages waver constantly), I'm stuck and desperate to figure it out. I've even tried the stock turbo charger, the stock charger for an old Moto X 2014, and as of writing this just now a Samsung quick charger for the giggles.
I have parts for all kinds of Moto X 2014/Nexus 6 lying around, so I took the risk of connecting a Moto X 2014 battery up to see how it behaved. It read the battery level around mid-seventies and didn't seem to drop at any exaggerated rate but still kind of bounced around a tad. It would charge at times, but otherwise still wouldn't show the battery as being charged. I didn't think too much of it because the 2014 is of course a different model at a much smaller capacity, so I didn't want to try leaving it on the charger for fear of overcharging. The only thing left that I haven't done is hook up the Play battery to another motorola because I don't have any screens to monitor progress and see how consistently it reads to determine if it's the battery that's somehow gone wonky.
So in summation/where I'm at right now: I'm having this same problem; I've tried both hardware and software tinkering to no avail; I feel this is still somehow kernel/software related, but I'm not sure how to completely obliterate everything to start from stock. Please forgive how scatterbrained I am right now, I'm tired yet wide awake and irritated with the whole situation; there's NOTHING I can find in the forums or elsewhere outside of stock replies like "are you using the original charger?"
My moto x play not change in normal it only charge in factory mode that to 75-82℅ only.

I have tried after battery fully drain, still it's not charging again I am charging mobile in factory mode. Is there any solution please help me. In factory mode i am not getting signal.
So no change in behavior. I did notice that when in TWRP that the CPU Temp value is crazy, and any reporting software says the battery is at -23.8° C and always cold, even on a brand new replacement battery (obviously send like that is what's keeping it from charging). I even went as far as to put a heat gun on it from a distance to artificially actuate any sensors and got nothing. The one time it did report normal temps it charged fine for a whole day but hasn't returned to normal since. This **** is maddening...
I know this is a long shot, but have you tried resetting the battery stats?
http://forum.xda-developers.com/showthread.php?t=1699687
I had this problem but yesterday I can solve that
First I put stock firmware
Wait for fully discharge
And wait full shutdown
I put an moto g 2013 charger (550mA 5V)and led stay on around 5 min but not charge
After put Nokia n86 charger (1A 3.5V)5 min and not charge
After i put an orginal moto turbo charger
And start to charge wait for 9%
Turn on the phone
Clear battery stats with battery calibration app
Wait for full discharge
Wait for full turn off
I put a Nokia n86 charger wait 5 minutes vibrates and start to charge like the beginning
Any other suggestions or solutions? Still my phone only charges in recovery mode. I have a aukey fast charger. Tried different kernels and roms without success.
The solution with the nokia chargers seems really strange and i dont have that type of charger.
Regards
Someone fixed this? I have the same problem and can't solve it. I have cm 13 by temasek and the first time the x play charged up to 83% but after a full discharge and a clean of battery stats, I olny could charge it via factory mode, like in stock 6.0.1
I dont know why but after i opened the phone and disassembled the battery it worked after putting it back together. Disconnected the cable to mainboard as well as nfc antenna. Then carefully pried the battery out. Its slightly glued to the mb. Then I held power button down for a few sec as read in a different forum. Afterwards I connected power cable back but left the battery next to the phone. Booted the phone and charging worked. Than I reassembled the phone Ehen I was sure everything worked. I was about to change the battery but now it works. I flashed different Roms and kernels without any improvment before. After I got it working I flashed a nandroid backup of a resurection Rom image that didnt worked before. Now its running perfect.

So, may the problem be in the pins when the battery is plugged into the mb? I'll try that! thanks!
Still having this issue, the solution with the chargers didn't work for me, neither the battery solution, suggestions?
How to solve the problem?

Same issue
My Moto X Play has the same issue. It will only charge in Factory Mode. I had this issue before at 10-11 months old and had it 'fixed' under warranty, now 2-3 months later the same issue has occurred. Of course the warranty is only 1 year...
Glad I am not alone in this issue but i wish there was an easy fix! Putting me off getting another Moto...
Same problem occurred with me( Moto X Play).
My phone was not charging, it was stuck in some percentage and was not increasing or neither decreasing while plugged in to charger. But when i put it into recovery mode, it charges. But that was not the solution to the problem.
So, i have tried factory reset.
but problem was not solved.
i googled for the solution, but couldn't find the right solution. And i was stressed (I have a girlfriend, and living in very distance relationship, for me a smartphone is very important).
And was thinking of buying a new phone but not the Motorola, but couldn't afford at the time.
At the same time, i thought of repairing it by myself, by fixing the battery properly.
Without thinking about voiding the warranty and Motorola support, i unbolt every screw of the phone. and finally , finally, finally i made it by removing the battery and fixing it again(charger was plugged while removing the battery and fixing, and phone switched off while removing).
And now my phone is charging properly.
Hope I have helped every person concern to this same problem.
Thank you

Unable to boot up, Red light when charging issue

I have been unable to boot up my letv 1s device, I have tried everything listed on this forum and other forum to boot up my letv device. Including removing the battery and reconnect them back again.
Recently, I tried to repair it to local phone repair shop, they told me it needs a battery replacement. I bought the battery from aliexpress and replaced them, but it still doesnt boot up.
The repair shop gave up and gave me back the phone and told me the EMMC is weak (I'm not sure about this).
I disassembly the phones and try to figure out the problem, I am guessing the problem might be with the charging board, I am posting the video here hoping someone pro could help me solve the problem. I'm guessing its the charging board because everytime I connect the device to the PC, it kept reconnecting when I tried to FLash a new ROM.
Here are the video of the board kept reconnecting when I tried to connect them to PC

I really hope someone with more experience could give me more insight about this, thanks.
PS: Please dont ask me to charge the phone again with original adapter and cable, because thats the first thing I tried and I charge it for more than 24 hours already (I even tried to buy a new adapter and usb type-c cable). Oh and I tried connecting to PC with the battery connected also, and it kept reconnecting.
Hi, I also have same problem, but still no solution.
Hi @casper2201 , @softkans and any one with the same issue,
I too had the same issue. It started with the charging rate becoming too slow (1% increment in 25 minutes of charging). I switched off the phone and left to charge for around 35 hours straight and came to find it 79% charged. Then I tried flashing the LOS14 after LOS13 ROMs but in vain. I also fiddled with the Kernel Adiutor, still no help. The charge won't increase when the phone is on so I left it to discharge until it switched off. Then the main issue showed up with red light always on when charging and blank screen.
I also posted about it here, but no one replied. Then I took a leap of faith and went to a local repair shop. He confirmed that it was a hardware problem and the charging module needs to be replaced. Just now I am coming from the shop itself after picking up my phone. Its working fine till now *fingers crossed*. He charged me ₹1300 ($20) which is a little high for the service but it doesn't matter as he was the only one ready to open it as there was the risk of cracking the screen.
So, summing it up, if you have the same problem as that of mine then you need to replace your charging module and I think it will be fine.
Charging module replaced.
Current condition of phone.
The rubber bands will help the adhesive strengthen.
Thanks,
Abhishek

Yesterday when I was done with setting up my phone, I put it to charge and the same issue has come again. Its not charging and the "Red light of Death" is back. Today I'm going to the repair shop again and see what he can do now.
I think this is the end and there is no point throwing away more money on the device anymore.

I really hope someone with more experience could give me more insight about this, thanks.
PS: Please dont ask me to charge the phone again with original adapter and cable, because thats the first thing I tried and I charge it for more than 24 hours already (I even tried to buy a new adapter and usb type-c cable). Oh and I tried connecting to PC with the battery connected also, and it kept reconnecting.

Sir same thing happened with me....phone is not charging red light alert and display blank...please suggest me what can I do
I want my data back from that and its not starting my data is really very important I can't loose that
Help me and tell me what can i do so that my data will not loose and my phone starts
Remove display and disconnect battery. If it won't be alive again that's probably power management unit problem and you won't fix that way.
