Hello, just about to pull the trigger on a new xperia ZU, but i wanted to see if anyone had any tricks for me to try on my Xperia Z. I was running near the latest CM 10.2 without issues for awhile now. Last night while i was bowling the battery died( nothing new happens all the time to me :) ). When i returned home i hooked it up to the wall charger for about 30 minutes, came back and still no life. I have tried multiple chargers and multiple cables with no luck. Device has been plugged into power all night and all day so far. When i attempt to power on with it unplugged i get the 3 pulse red led. When i hit the power button with it plugged in all i get is a solid red LED. Nothing more, nothing less. Cant get into recovery or anything. Most of the time a hard brick involves a mis flash or something along those lines....any idea what could have happened to mine?

It might be the battery...
Its not advisable to full discharge the battery but it seems that u did it a few times..
The battery might not take any charge as the red indicator means low battery...
Tried a new battery,i know after removing the rear panel n say good bye to water resistance but is worth a try...
Or u can send it to me for free if u wanted to throw it away... :D
hope this helps...

Had the same thing happen

I had the same thing happen to me. From what I read trying to troubleshoot it seems like the Xperia phones in general can take 30 minutes + after a full battery drain to even register that a charger is connected. I would try just connecting it to the Sony charger for a few hours and see if that works.

There is also a tip about holding down the power button when plugging in the USB charger and continuing to hold the power button until the phone turns on. Unfortunately, can not find the original post right now. EDIT: Found it. http://talk.sonymobile.com/t5/Xperia-T-TX/Xperia-T-Wont-Charge-Turn-On/td-p/252686/page/4

In my case the red light would not even come on when the charger was connected but would come on if I held the power button down while connecting the charger. After I did this for a couple minutes the phone booted and has charged normally ever since.

So its a mixed bag. Try just charging it for a while on the Sony charger or wall charger (not USB). Or try the power button trick.

Lesson I learned is I will not let the battery completely drain again.

Ahhahha it came back alive! I had tried pretty much every trick that has been suggested and it just wouldn't charge or start to boot. Left it on the main charger again last night and still no luck this morning. Again I decided to plug it into my computer's usb port( I did this multiple times already ) and I hit the power button, a backlight came on!!! and then sure enough there was the free xperia logo! I have no idea why it finally decided to power on, but its showing 1% battery so it was truly not charging any of the times it was left on a charger, computer or mains. Thanks for the responses guys, I appreciate it!

I know this thread is pretty old. But I'm having the same trouble. Xperia Z got bricked after battery drain. It wont recognize charging, i kept it on charge two nights in a row now. It did show a red LED while charging for some time and nothing else, but now its back to being stone dead. tried holding down the power button trick, didnt budge. I thought you can only hardbrick it by doing a wrong flash/update. dont know what happened in this case. is there anything else I should try or just take it to a shop and ask to change the battery?

man, try with a new battery, here in my country cost 14 euro . Or go in a service or buy a multimeter and measure the current of ur battery. Normal they from service will give u electrosock to bring it to life. And if will dont work i think u must sell it on piece and buy another

Same problem with my Z3 Compact: one day phone became hot and started to discharge rapidly and when battery became empty, cannot charge and cannot boot, only red LED is ON. I changed the battery and phone booted again. BUT when battery was discharged completely, phone cannot boot again, only red LED is on when trying to charge.
Looks like something wrong with motherboard is happening... :(

Xperia ZL battery completely drained, not starting up

I know this thread is old one, but I am having issue with my Xperia ZL. Its battery drained to zero and then whenever I plug in my charger, screen starts, Xperia Logo pops up, red light also starts and suddenly everything goes off. This goes on and on infinite number of times. Phone heats up but it doesn't turn on. I had issue with my battery, a couple of months back, so I replaced it with new one. If anybody has any solution about this, please let me know.
