My battery is draining while charging at wall socket?

My galaxy s4 battery drains while charging.
My 4g data is turned on and wifi hotspot is also turned on. I also play Clash of clans while charging.
Should I replace my battery or my charger?

Download "Galaxy Charging Current" from the play store and check how many amps you're receiving. You should be getting more than 800ma for your phone to charge properly.

I'm receiving 600ma from my wall socket. Is the charger faulty?

Isn't this related to the battery swelling issue discovered recently ?

The battery isn't swelling. It lasts like 8 hours if no data use. So i think its not because of faulty batts.

Are you using the original S4 USB cable? you need a very good usb cable in order to change with high ma, it should be about 1500ma if you are using a good usb cable (with the original charger)

Depends on the firmware/kernel. Newer (stock) firmwares (>MGA) limit the charging at 1200mAh while the screen is on and 1900mAh with the screen off.
Custom kernels can charge at 1900mAh with the screen on.

Some cables are unable to generate more than 600ma. If it is the original Samsung charger, change the cable. If it is the original cable, get a 2A charger. If it's both, chances are, its the cable. Good luck.

First day i was testing different wall chargers (Samsung stock and non Samsung) with different cables combinations using a current widget. Results: original white Samsung data cable still in the box (bad impedance causing low current) and using stock wall charger with a generic data cable better than original.
We all assume hi is trying stock all charger and stock kernel...

The limit is the same (1900 with original wall charger and good data cable), the 700 mA difference is because screen consumption plus non idle cpu state... It is, 1900 always enter in the device, 1900 enter in the battery if no consumption (screen off), about 1200 enter in the battery if screen and cpu consumption (on).

Yes, it is just a consecuente from the 1st Thermodinamic Principle... The consumption of a turned on screen and a working cpu is not zero...

You don't say, really? :good:
Older firmwares let the phone charge at 1900 with screen on or with screen off. More recent firmwares limit the charge to 1200 when the screen is on.
With a custom kernel this can be changed back to the original 1900, with the screen on. What is so hard to understand about that? No need to go into science again, I do understand all that irrelevant stuff anyway.

Thats amounts are not the limitation into the phone, but the net current into the battery, the difference between that limitation you refer and the actual current consumption for the screen and cpu. I think it is not complicated to understand... You don't need to explain me about what custom kernels can or can't do about it, i know, i collaborated with Aaccount here in xda for enabling "fast charging" on his A1 kernel for our Samsung Galaxy Tab P75xx...

Nexus 10 dead, pogo charger needed

Hi mates, I've had my N10 running perfectly for years, the minute I gave it to my wife it suddenly died (no kidding), I've tried several methods to charge it without any luck, so my last option will be to obtain a pogo charger, though the problem is, there are no more pogo chargers manufactured, so my question is: Does anyone on the forum has a pogo charger on sale? For I don't resigne myself to loose my tablet out of lack of charger
I know there are dozens of people looking for this pogo charger as well, I just hope I can get one.
Thanks a lot in advance mates.
btw: there should a listing on swappa for accessories too

Thanks for the second link, I didnt found that before, as for the magnector link, I even wrote them support and they told me they are not manufacturing that cable anymore.
Will try with the other cable.
thanks a lot.

I'm in that same boat. My N10 stopped taking charge just yesterday. Whenever I plug it in Ampere goes red and says "Unknown" instead of "Charging" no matter what cable/charger combination I use. Decided to just shut it down when the battery got to 4%. Is it safe to assume this pogo cable is my only option?

mine has just stopped charging too, although it actually says charging when i could boot into the os, now im trying to save the tablet through twrp but its stopp botting into that now, i just get a white battery icon with a lightening bolt in it on screen.

Mine still charges, but the current rate is really low, so it takes forever to charge it. Furthermore the rate changes every time i plug and unplug the cable.. When I'm lucky, I can get it up at 1A I guess its a matter of time before it dies on me too. It's also very sensitive when it comes to cables and wall adapters (it effects the current rate).

What ROM a you using, guys? Same problem here on CM13 last week nighlies. I just flashed stock LMY49J when the battery went on ~40℅ and at this moment N10 seems to be charging battery again (+7℅/h @ 1.2A charger).
Weird stuff, same issue on lot of devices at the same time..

Mine has been fine then flashed the latest CM nightly on Saturday so 20/08/2016 and now i have ZERO battery and it just sticks on 0% even when left to charge without a os booted.
I've tried different charger cables as well as plug adapter and a USB from the computer all not working.
Do i need to get this pogo/magnet charger or is it something that's happened on the CM Nightly (i did notice they changed the batter charging animation with no OS booted)

Sorry mate! Everybody who is talking about the pogo.. I am guessing it won't solve the problem ( it seems to be a quite bad kernel update or something) and the tablet will not charge.
The right solution is to charge the battery alone, try to use an old one with a residual charge or what is more simple, buy a new one (they will be around ~50% charge) and then, flash some stock ROM at quick as posible.

I'm absolutely in the same "no charging" boat, unknown battery, ...
The only possibility for me is to charge my N10 when it's in recovery, nothing else is working.
Hope it will be solved asap from the cm team

Mine has always acted like that. I'd plug it in and get it charging around 1.2-1.4A and then leave it. The rate would go down if the cable got moved around so I just didn't use it while it was charging.

That's a really weird behavior.

Think it's just the cable I use. It doesn't really fit very snugly, has a little wiggle to it when it's plugged in.

I'm not having any luck charging in TWRP. Left it plugged in for 90 minutes then booted into CM to check the battery level and it was 0%. Was somehow able to boot back into TWRP, might try flashing an older version of CM and and see if that helps, if it doesn't die completely first. :/

If you're using latest twrp you can follow charging level in twrp ... It's easier.

Are you talking about removing the battery and charging it on its own? Because my battery is now officially dead. Screen flickered and it went black while trying to flash an old nightly.

I think it's easier to buy a new battery via Aliexpress or similar than trying to find a pogo and see if its going to work.
Both solutions are hard to take.
If you were able to enter bootloader o recovery and try to charge from there to see if works...
Enviado desde mi Nexus 5 mediante Tapatalk

Charging over USB works while the tablet is in bootloader mode.
With pogo cable charging works in all operation modes.
I ended up flashing the Google Nexus 10 factory image (deleting everything of course). Afterwards charging over USB worked again.

Well, all hope is not lost after all. Left it plugged in all day and it had enough charge to boot to TWRP again. Flashed a random nightly from July that was still on my device and let it charge some more. Now it's back in action. Phew! Thanks @v1r1at0 for the tip on downgrading.

Won't fast charge.

I just noticed that my phone won't fast charge. I believe it was fast charging yesterday but today it wont. Phone hasn't been dropped or anything like that. I checked the settings the fast charging is on, and I restarted the phone. Ive also used multiple chargers.
Anyone else have this problem and or have a fix? Thanks.

you washed the phone?
then use original cable and charger.
if the phone has high temps he don't fastcharge. cool it

i have observed it many time, my phone simply will not fast charge even with original charger and cable. And i am on stock version. What helps is to remove the charger from electrical outlet , and plug it in again.

Okay, so i used multiple chargers and multiple outlits. I factory restarted the phone. It is also not being recognized by a computer anymore

Thank you thank you thank you! Unplugging charger from wall and then plugging it back made fast charging work again! I cannot express my gratitude.

Slow battery charging & charging stops after turning the screen on

Hello, guys. I hope you all are great.
I have a concern... I don't know wether the issue I am facing is specific for the XT1575 or is a general android problem. Here it is:
I have a Moto X Style and I am facing this problem: slow battery charging. There are 2 symptoms that I noticed:
1. When I turn on the screen after starting charging with the screen off, the cell phone stops charging (using fast charger or ordinary one). To continue charging, I have to unplug and plug again and again.
# I believe the fault is software. But I am not sure about that.
2. About 5 days ago the turbo charger (and common charger) is charging very very very slowly. It is not normal. To charge 1%, it takes about 20 min. I ran the Ampere app and realized that the current during charging is between 230 and 260mA. If I am not mistaken, using the turbo, it should be at 1600 to 1800mA.
I realized that fault after a trip. In it I needed to charge the phone in the USB 5V car charger and did not charge properly (same symptom described above).
What have I already done testing?
- I had a let the battery drain 100%, so that I started to charge. Nothing has changed.
- I had tried charge using the fast charge that came along with the cellphone and ordinary ones. Nothing has changed.
Has anyone had this? Is there any way for me to go and fix it?
The cell phone is awesome, although the battery is your biggest con. Without the turbo charger it gets me some doubts regarding if I can still have it...
I really appreciate your help.

One extra update: I have just factory reseted and everything is still the same as stated previously.
Something says to me that the issue is software. The reason is that I use a pin code to protect my device and after I turn the screen on (after typing the pin), the device stopped charging. So that I had to unplug and plug it once again to continue the charging.
The thing is that after I factory reseted and realized that the issue continued, I tried to suspend the use of pin code.
Result: the second flaw stopped. I mean that after turning the screen on the battery continue to charge normally.
Now the fast charging pretty slowly still...

You most likely have a bad cable or adapter... there is no known software issue with charging on any Moto X device.
Less likely: bad USB port in the phone or bad battery
Even less likely: bad main board in the phone
Find a friend with a Galaxy S7 or S7 Edge (just saying because they common) and plug into their stock charger, it should pop-up the turbo charging toast messaging within a couple seconds.

I see... So, I agree with you. Even based on that my Moto x is really new. No more than 1 month...
I will look for another turbo charger and try once again.
Oh, and one more thing, even the cause may not be related to software, I intend to downgrade to 5.1 and try once again. If nothing occurs, I will update to 6.0.1 and move my life on.
Thank you in advance!

Don't do that... Why on earth would you want to do something as dangerous as downgrade?

I don't know. Maybe the fact that it can be a software issue...

It's not software... But I'm no expert either. If it is software you are the first person to discover it. Try a new charger or just connect a buddies to test it.

Unfortunately, I believe that the issue is hardware related.
I charged with another fast charger and problem persists...

2 month old ZTE AXON 7 won't quick charge anymore.

My phone is two months old and has ceased to quick-charge. Actually, 90% of the time, it will only charge when powered down. I use the factory charger and cable but get a message that I need to use the original charger and cable. Catch 22?
I bought it at Best Buy so I took it back to them this evening. My charger is fine as is my cable. Best Buy confirmed that my issue is a factory defect and politely sent me on my way. I take care of my phones if nothing more than the fact that I've had to replace micro USB ports in the past. The weird thing is that when it charges powered down, it seems to refresh to full battery very quickly.
Has anyone else had similar issues? If in fact, I do have to deal with ZTE, what has been members experience?
Thank you for letting me vent.

U can test your charger using USB volt amp reader on another phone which supports quick charging.
If charger works as it should then u need to test your phone with multimeter to see how much current it draws while phone is powered off without charger (battery only).
But that means you need to open 2 month old phone which i dont recommend if u have warranty.
Axon 7 draws about 2.66-2.68 amps while in quick charging mode. Volts i forgot but i think it was 6v. I'm not in shop at the moment so i cant know exactly.
But for amps i remembered.

Wallor77, thank you for your reply. My charger is in good working order. In fact, I have several 2.0 and 3.0 chargers. They all work fine on my Samsung Galaxy Note Edge. The Samsung displays "Fast Charger Connected" on the lock screen.
Now my ZTE Axon 7 will not charge while it is powered up. As soon as I turn it off, it charges just fine. This is really annoying!

If your charger and cable are OK, perhaps have you recently installed an application which limits the power. Such methods exists in some antivírus to preserve the health of the battery. It's just an idea.

Same thing there. If it charges normally while power off u need to see how much amps. USB volt amp reader is a good little device. I recommend for everyone to get one. It cost about 15 bucks. From there it's all about elemination process to diagnose proper issue

I second this. But $15?! You can get them for about $5 on aliexpress!

U have USB volt amp reader with both volt units, amp units, time duration and mAh over time charged value. But 15$ was about avarage price listing. I'm sure there is cheaper as well.

UPDATE: 6/2/17
I ended up sending my phone to the ZTE repair center in TX. It took about 3 weeks to get it back. There was no explanation of what was repaired and I received my original phone; not a refurbished one. All I know was that it was covered.

I am in the process of returning my 3rd Axon to ZTE. 2 of them have had this problem. It's definitely known because when I was talking to them and told them what was happening they just kind went "yeah ok" and fast tracked the whole thing. Thank god for this warranty, their quality control is ****e.

anyone noticed that occasionally it stops charging?

Last night, mine started doing this. It goes on and off about every two seconds. What's weird is it only does this with the quick charger. it slow charges when connected to a PC usb just fine. Its not the OEM charger either since my wife's quick charges just fine with the exact same charger.
Guess I'm going to have to call ZTE....

Mine suddenly stopped quick charging - I have 3 different chargers that work fine with other phones except for this one. And chances of all 3 of them going bad at the same time are slim to none. Tested different cables as well, but again same result. It charges with normal speed even when connected to QC3.0. Tried wiping cache. I think it's no different if I turn the phone off. Think it might be time to move on. Had it since December 2016, so I guess it's nearly 2 years old now. Still shame.

Quick update. Swapping batteries (OEM) hasn't helped. I wonder if this is software or hardware related

Let me add to this thread. I'm also not getting quick charge anymore for maybe a month already. Tried different cables, booting to safe mode, etc. There are few instances where i see quick charging but very rarely. I was thinking it's my usb port but I haven't opened my phone yet to verify.
