XZ Won't Start Unless connected to USB

Hi guys I have strange situation with my Xperia Z.
XZ won't start and load OS unless connected to a charger! When unplugged XZ gets to SONY logo, or animation or briefly boots and then dies. Battery is FULL. I've charged it over the nights.
When connected to a USB charger it starts normally and works until disconnected from charger. Then dies after 5-30 sec.

I am experiencing this behaviour after OTA update to newest firmware 10.5.A.0.230. Previously I had rooted 10.4.1.B.0.101 which worked perfectly.
I have tried to flash 4 different ROMs and with all of them XZ dies unless connected to USB charger.

Finally Iíve managed to get restore to original 10.4.1.B.0.101 but still same behaviour.

Please help! I cannot find any similar issues on forum. Tnx!

I bought the battery from eBay and changed it myself... Working like a charm now, the downside is I lost the water-resistant feature... But hey, as long as the phone working find is good enough...
