Hi,
I've recently bought a Sony Xperia ZR refurbished. It was really smooth and all, then suddenl it stopped working. It turned out it was the battery which was empty. I bought a new official sony battery, and the same thing happened to me, but I had the time to take those screens.
I've tried charging it offline, while turned on, with fast chargers, with a sony official charger... I don't know what I can do next!
Thanks in advance for every answer or piece of answer you can post.

A lot of people seem to have this problem and it seems to be the usb charging board that is faulty, some said that changing the charging board fixed the issue for them You should try wiping cache in recovery or even a factory reset before you opt for swapping the board.
Or go for an external charger.
But what about the temperature sensor that shows -30°C? Is it linked with the usb charging board or is it something else?*
And I can only find micro usb ports, not the entire charging board for my device... Do you think there is a way?
I've already done a factory reset before flashing a CM rom so it must not be in cache.
I have some new informations that might be helpful!
First, when I turn on the phone, it always starts at 6% then slowly grow until the real %. Is it then a hardware or a software issue?
Also, friday, I let the phone charging through saturday within offline mode. The battery was still to 20%. However, I charged it again sunday morning for 30-40mn and it was filled to 60%! (the higher % I ever get)
I don't know if it can help...

Hi all,
I have had a TF-101 tablet for years, and recently bought a keyboard/dock for it. The dock wasn't charging, after trying all of the strategies to make it charge my advice was to buy a new battery for it.
New battery is now installed but seems to be giving weird results. The dual battery widget is reporting either the correct charge level for the battery or 0%. It seems that when it is reporting, the dock battery works - when it isn't, the dock battery is ignored.
In testing I first charged everything up. The charge cycle looks like this on the dual battery widget:

}
Note that the dock battery has charged from 70% to 100%, when it was reporting a charge. The green indicator came on at some point also (which I had never seen before).
On discharging it looks similar:
Note here that the dock battery seems to have slowed down the discharge of the tablet battery, when it was reporting a charge.
The tablet battery charges and operates normally when the charger is plugged into the dock. All other keyboard functions work fine.
Does anyone know what the problem could be here? Thanks in advance for any help I may get.
Hi there !,
The dock battery may not be connected properly. I reccommend trying on another TF101 tablet, to isolate the issue between the device or keyboard .
When you post the results, i will be happy to help further
Please hit thanks if i helped
Hi, good afternoon
As the tittle says:
phone used to work perfectly, and not except this issue, still works.
so
i plug any charger, the screen says : SLOW CHARGING (takes hours) tried all kind og chargers, from the alcatel of 5v 2 A, to others of 5v 1,5 A 5v 500 Ma
i plug in the pc, the pc doesn't detect the phone. is not a cable problem, got other phones and work with same cable.
i already tried all the methods from page 1.2 and 3 from google, cables/chargers/drivers. blah blah

same problem
Hello. I have exactly the same problem for a few days. I tried different cables and chargers. I tried to reset the phone. the problem is still here. I thought the problem came from the battery but now that I see your post I think it could be a software bug ... or can be a planned obsolescence :-/
if you find a solution I'm waiting ...
Hello, my English is extremely bad so I will use google translator.
The essence of my problem is that my Samsung gear s3 R765V may suddenly turn off.
It does not depend on the battery charge, they just turn off. Then I start them again and they can at least spend a day working on the same charge. And so, twice a day, my watch died and got up again.
I went to the master (we do not have Samsung service centers), and he found a problem in the condenser which, due to moisture from the hole under the speaker, began to rot.
The location and number of the capacitor I will indicate in the photo. Capacitor C446

After that, the device started and turned off a couple of times. The master said that there might be a problem in the battery and could not help.
On the same day, I was able to once again start the clock, but they turned off after an hour. And did not turn on until the evening. Then I opened the back cover and looked at the place all the cable and they turned on again. And we worked all day on the same charge!
Now I can’t turn them on anymore!
1) The battery is charging and the screen lights up!
2) The buttons work, respond to clicks and show the charge level.
But the system itself does not start in any way. Although before turning off immediately started again.
I believe that the problem is in the capacitor, which was replaced, but not correctly selected!
My question is:
1) What do you think is the problem and how to solve it?
2) What is this capacitor and how to replace it correctly?
3) Is it possible to remove it altogether and try to start the device without it?
If you have questions, ask! If I can understand you, of course)
Thank you
Hi guys! Greetings
So since my phone hasn't able to do fast charging (and I did all possible available options, like use new cables, change the charger, changing the new flexy charge, clean the stock micro port USB on stock flexy charge, checked the settings to turn on the fast charging, bought a new battery with same capacity, and so on). And all these options don't solve my issue, I even went to repair shop which they only replace the flexy charge to a new one (they guarantee it is original and not some chinese-look-like).
But I had in my mind that something on my IC is damaged or has a faulty power management. Maybe. I've had discussion last month in this forum too. I'm frustrated with normal charging like I should wait for six hours to complete full battery. The math didn't do the right thing. If 3220 mAh divide by 1667 mA (I got this number from a stock Samsung charger), it should be around 2 hours. But apparently, I've come up with a new idea. I bought a desktop charger which comes like this:

}
It needs to connect through an adaptor that outputs 1A. And connects it into the desktop with micro USB. It's practical and easy to use. It's a good accessories.
My questions is:
1) Do you guys know alternative charger that similar in this photo? Maybe that could output more than 1A. Or any other option, so I could charge my battery without plug it in my phone.
I don't like use extended battery that exceeds capacity of a stock battery. I fear that it could damage my phone for some reason
Hey all, sorry to post this like a totally professional noob but, this phone is kinda give me headaches and I am totally ON to reflash the rom or even modify the kernel if needed.
The problem manifests as this with this phone:
* Everything works fine, with the exception being the charging (and some other minor glitches like a custom fingerprint can't be added anymore).
* It does not charge when ON, or when TURNED OFF and the charger screen is showing. More detailed: When on, the battery discharges even when plugged in and "charging".
* When turned off it shows that it is charging, and doesn't go above 1%. But here comes the tricky part: When I press the Power Button + Volume UP I got the menu with: Recovery Mode / Fast Boot Mode / Normal boot. I left it in that menu to charge and I got back to 40% in a few hours, 50% only one time, I guess it's a slow charge in that mode but at least it's charging.
As soon as I boot it up properly and with the charger connected, battery begins to deplete instead of charge. I bought another 2 chargers and 2 cables, same issues both on AC and on USB to a PC.
What seems to be the problem? Faulty kernel? Some other things?
If I need to reflash it I don't know the tools needed for this phone and especially, the stock rom.
Thank you for your attention xD

Take it to authorized service center and let them try to fix it.
