Today I had the experience of having this problem
I've read in several places about it, but he is already well known


My experiences and attempts:

*disconnected from the charger it goes into bootloop
*connected to a charger it turns on and works normally
*loads very slowly (original charger and cable)
*battery percentage is crazy (for example to restart it jumps from 14% to 76% and otherwise)
*when disconnecting the charger it works for about 1 or 2 minutes and turns itself off

some search i found in this segment:
Sony Mobile Battery Testing App posted by @droid102

then...



as well as several people have noted, it is a battery problem!
Maybe any particular type or configuration and calibration? I do not know!

among several people who reported this problem this is what catches my attention:
http://forum.xda-developers.com/show....php?t=2534327 posted by @Osni~* Osni~*

especially a posting made ​​by @CokeJunkee
http://forum.xda-developers.com/show...68423271086067

However I will send the set for repair (still under warranty)

any feedback is welcome!

This happened to me! My had ZL had already been replaced once and after about a month it started showing the same symptoms. I flashed the stock firmware twice just to be sure it wasn't a software issue, but the problems persisted.... So i took it to the service and now they're gonna replace it again (obviously without any charge)! It is a battery problem and hopefully I won't have to go back to the service center with the next replacement.

Yep, exactly the same as my case.

When the replaced cellphone had the same problem, I called Sony and they wanted to replace It again.
I said I wouldn't send it for replacement because the (then) third one would have the same problem and I would have to wait another month or so without the cellphone (not to mention the warranty was already at half).

I requested the refund, they did it in 2 weeks if I can remember correctly, then I waited 3 months with a crappy phone and now I'm a happy owner of a LG G3.

i had sorry for you and in some cases were in the same boat..
My battery also crazy, sometimes it went down to 14% from 92% and sometimes it's dead when it reach to 70% and below..
i know fully discharge and charge again would fix this but it wont be long.. It's gone for about 3-4 days and later.. My phone went drunk again..

in my mind, i looking for a phone with removable battery (samsung is my quick choice). But it's hard for me to leave sony and hard for me to leave "a full of memory phone", my xperia ZL..
i been using sony (ericsson) since K800i was released till now.. The XPERIA ERA was coming..

my warranty will expire in about two months

assuming he was sent to warranty I would have to have this extended period... huh?

I will make it clear to receive the product back if he face the same problems will want a refund
even if need to seek my rights

this problem needs a "recall" (since many people had this problem and was contacted)
consumers would look with brand new eyes

great news friend, it may be helpful to me if a new problem happen in the future and certainly many others

(My conclusion so far) this problem happens when the device reaches high temperatures that eventually comes to corrupt welds trails Battery

Hi, Nebixts!!
Only a pencil type soldering iron, wire solder, stannum and a insulated wire... disarm, and rearm the device...its very important calm and focus, good luck!
