Xperia Z won't charge unless completely drained.

[mashare]

Few days ago I noticed that my Xperia Z won't charge. I tried force restarting, charging when turned off, nothing works. The cord and power outlet is fine. I decided to slept on it, leaving my phone on the charger and woke up the next day with my phone fully charged. I tried this yesterday and it works like that as well. however I cannot connect my phone to the computer  (the computer says your device malfunctioned or something like that) or charge it when it's not drained. Any idea what's going on?

I have this exact same problem.  Not charging from a wall plug unless completely drained. Not recognised by computer.  Have replaced the battery and still no good.

@dehme999 

check the suggestions on the first page, perhaps you need a brand new battery

I having same issue.

If wish to charge phone .have to first completely drain it. By repeated start and shut down.

When has zero charge,  able to charge it.

Is difficult to manage the phone.

Strange no one could come up with a solution to this problem being faced.

Any body had a solution?
