Magnetic charging dock not working

My charging dock doesn't seem to be working. It's the original one that came in the box with the Z1. The phone does recognize the dock as it automatically opens the photo slideshow thingy and switches to landscape mode, but it's not getting any power through the dock. I've tried plugging the dock into many different wall adapters, including the original one, but it still refuses to charge.
Is the dock broken in some way or is it the phone's connectors that are causing this? I only got the phone a few weeks back and I don't understand why it's doing this. The dock wouldn't charge it even the first time I tried it, and that was just an hour or two after unboxing.

Not sure if this is a related issue, but when I use the magnetic charger, it charged the phone relatively quickly the first time I attached the cable. Subsequent charging after that seems to be significantly slower (takes more than 6 hours to reach 100%).
Something wrong with the cable or the connection?

Try the other magnetic charger
You can use a magnetic charging cable to test that is the dock broken or are the phone's connectors broken.

First of all ensure that the copper connectors in the dock as well as on the side of the phone are in contact when you place the phone in the dock.
I too have purchased a genuine Sony Dock - DK 31 from Hong Kong as it is still not available in India. At first I too had the same issue of not getting any power through the dock. But I dis- assembled it to take out the cable and directly connected it to the phone. Great ... it was then working fine. So i re-assembled it back to normal and now it is working great. But at times i have to try 2-3 times to get the contact alignment right when placing the phone in the dock.

Cable can be removed from the dock by simply removing two screws from the bottom of the dock

Yeah ... Genuine Sony Magnetic Charging Cable EC 21
Connect and See

Using the very same cable... In settings and the status bar it shows that it's charging, but very slowly. After an hour or so, even asleep, I get a message that the phone is discharging faster than it's charging.

I have the same issue. The 1st time it was ok, but now after 3 hours nothing happens. This seems to be a very good crap

[Q] Magnetic Charging Cable: Charging Time?

Bought a magnetic cable from ebay, which had all the sony retail boxing but the build seemed cheap. After a week usage, I am noticing terrible charging rate. Having kept my phone over night for charging, I still see only 5-10% increase. But when I switch to USB Cable, it charges noticeably faster (Quick Charge)
So to verify that the cable had issue, I installed this app https://play.google.com/store/apps/details?id=com.manor.currentwidget
Would like to know to how much charging current do they get on USB and on Magnetic Cable.
Mine are as follows.

I had the same effect once but it never happened again. I noticed the magnetic charger was charging extremely slowly but the issue went away after I had fully charged the Z1C and it never came back again :S.
You've probably checked, but make sure the magnetic charger is sitting properly in the connector?

The easiest way to check is to install elixir2 and check how high is value. In my case my magnetic cabel charge fast as normal usb cabel. Average speed of charging about 800-900mah when i do something on phone. Original charger can provide 1500mah so when you use your phone you must 1500-that what phones need=charging value. I had another magbetic cabel earlier and it charge terribly slowly. But new one works gr8.

Same here, got a cheap cable from eBay and keeping the screen on decreased the battery status quicker than it actually charged. 5-10% over night. Different cable, all fine. I even modified the contacts of the first cable to ensure a proper connection but that also didn't help. Some cables are just trash. Now I ordered another two of the second cable and they also work fine, same charging speed as via USB.

Battery Issues - 65+ hours to fully charge?!?!

Hello,
I discovered a weird issue with my phone this morning. I woke up and the battery was sitting at 64% after charging overnight. That seemed a little weird so I tried doing several different things (battery pull, clear the cache, etc...) to see if it would correct the issue. It did not. I just got done draining the phone completely and then plugged it in. In about an hour's time, it charged 2%.
The only thing that I have not tried at this point is a full system restore :crying:
Has anyone else experienced this issue? Do you have any ideas of things for me to try? I am willing to try anything before using a full restore as a last resort.
Thanks,
LBS
EDIT: Well, I dug out an old blackberry wall charger and cable and it immediately fixed the issue. I think its a bad LG charger and USB cable. I guess ill toss them.

I've experienced this. Does your battery stats page look a bit like this?

What charger AND USB cable are you using to charge the device? While I was using the bundled LG charger at the time, I was using an old HTC MicroUSB cable I had from a previous device when I encountered this problem. When I used the bundled LG MicroUSB cable instead, the device charged normally.

I've been using a 3rd party 6 foot long USB cable with a third party rapid charger. Last night my wife needed to borrow a USB charger, so I gave her mine and used the LG provided charger and cable for the first time last night. I hadn't really thought about it. Maybe its a bad charger?

Could possibly be that. I think the G3 might be a little picky with chargers and such you use with it, I'm not too sure as I've pretty much used the G3 wireless charging dock to charge my G3 (and that is very picky with what you use with it, if it's not at least 1.8A then say hello to constant beeps and errors, my old 2.1A Nexus 7 charger seems to power the dock fine.)

SM-T800 Battery problem

EDIT: Please move this to Q&A and help section.. sorry.
Hello fellow tablet users.
Since the lost 2 weeks my tablet has been acting weird. It jumps alot on the battery levels, one second having 50% then 13% then suddenly 3% then plugging in the charger it has 50%.
I've tried to charge it fully then making a battery calibration but with no luck.. what should I do next? Full reset?
Kind regards,
Ratty

If you have the 8.4" it`s most likely an bad battery connection, due to an bad power connector or the part of the connector that is soldered to the motherboard coming loose, it`s an common problem with the 8.4" with people bending it while in back pockets ect, less of an problem with the 10.5" as you would need an hell of a back pocket.
Samsung knows about this problem, and according to one 8.4" owner replaced the battery connector with an more heavy duty version, some people say to solder the battery wires directly to the motherboard.
It`s quite easy to open the Tab S, lots of video`s on youtube and you just need an plastic pry tool they call an spluger or an guitar pick, I got an spluger on ebay for £1 an replacement battery is £9 an full kit is around $60 for battery and tools if you can do the job yourself.

Reset won't solve a hardware problem, it's very common in Samsung tablets : cracked or loose battery connector : male and female.
This is a close look of female connector:

If it's not fully contact with male connector's pins, you will have battery fluctuation in capacity. The fix is simple: push the opening closer for all six cables.
This is the male connector , it's re soldered to fix battery quick discharge or capacity fluctuation

I'm having this problem for a long time on my TabS 10.5". I think it's time to discard this device but I'm low of budget to buy a good tablet now, is it secure to open it and bypass battery using direct connection to charging cable from the original USB cable? There are some videos on how to do it, but none of this device.

They are not engineered the same as laptops. They always run off the battery, whether the tablet is plugged in or not. This is a series arrangement. A laptop has power source switcher inside and can run off either; that's a parallel arrangement.
The battery completes the circuit. The charge cord doesn't connect directly to the tablet because the battery is in between. Outlet-->charge cord-->battery-->tablet. You can't just jump over a step.The battery completes the circuit. The charge cord doesn't connect directly to the tablet because the battery is in between. Outlet-->charge cord-->battery-->tablet. You can't just jump over a step.
They are designed on an idea that the user will use it on the go, rather than sitting at a fixed location connected to a charger.
As such, the internal circuitry of a tablet allows the device to work only when the battery is connected to it.

Bypass the battery for direct connection
Hi,
I have a similar connector for the battery on a Samsung Tab GT-P5200.
I want to directly connect the (two) wires from USB power source and bypass the defective battery and the normal mimi USB connector.
Therefore can someone help me out with matching the colours?
Tere is just +-(red/black wires on USB) and the connector from the battery has two red, two bue and two black.
I presume at least two should charge the battery and other two should transport the charge from the battery. And the blue ones maybe for control?
Please give me your though, or maybe suggest other place on the bord co connect directly.
Thank you!

Nexus 7 2013 charging failure

The Nexus 7 2013 I have started charging intermittently. Replaced the battery as it was quite swollen. Eventually charging failed completely. Confirmed it was not the USB socket. Replaced the charging board ME571K_SUB with a new one. Still no charging. Will a Qi wireless charger work?
Any advice.
Thanks.

The N7's charging path:
1 charger
2 USB cable
3 daughterboard (replaced)
4 the wide, silver, ribbon cable + PCB connectors
5a motherboard
5b software
6 battery (replaced)
Are you sure about #1 and 2?
Have you re-seated #4 connector at the mobo's end?
5b - is it charging OK when OFF or in fastboot mode or in TWRP?
If the motherboard is faulty then Qi may not work but "no battery mod" will work for sure. A swollen battery indicates that your N7 is constantly being (over)charged, so the no-battery mod can be a perfect solution in this situation as you do not mind USB cable always connected.

Many thanks for your reply and the insight into the charging path, very helpful. The no battery mod is pretty major surgery!
Regards 1& 2 I have tried different chargers and cables to no effect. The female USB connector is solid and delivers power to the daughter board.
4. I checked the silver ribbon cable connectors at both ends and note there is a small amount of damage to some of the mother board connector contact pins. When time permits I'll ring out these contacts to check for open circuits. There has been trouble in the past with sensor connections in this connector because of the battery swelling pulling on the ribbon.
I'll report back.

I rang all conductors in the silver ribbon cable from the back ends of each connector, no open circuits. Resistances ranged from about .3 to .7 ohms. Still no charging.
Seeing the intermittent way the charging failed I think I have to conclude there is a hardware failure on the mother board and it is now toast.
Do you agree?

The silver ribbon cable's connectors and PCB soldering may be faulty. Please do these tests:
1. disconnect battery, connect charger, press power button
- the notification light blinks 5 times
2. disconnect battery, connect charger, measure voltage on pin #1 of the mobo's battery connector
- fluctuates around 4V
If both tests fail, I bet there is the silver connector's problem.
If only test #2 fails, the mobo is definitely faulty. Proceed with the no-battery mod

I performed both tests.
1. No flashing white light.
2. Close to 0 volts on battery connector pin #1.
Performed the "no battery mod" and all works well. That link led to many interesting posts.
Many thanks for your help. Have a great 2021.
