Z1 can't turn on after discharged battery

[stix1]

I have low battery on evening and on morning my Z1 was turned off. I plug it into wall charger, wait about 30min and try to turn it on but no success. So I wait about few hours and try it again. I try turn on + volume up, try to plug into computer but nothing happen. If I press only power button for few seconds, red led blink three times. Anyone know what to do?

Hi and welcome to the community! Since you're new please be sure that you have checked out our Discussion guidelines.

The three red blinks usually indicates flat battery. So charging it for an hour or two should fix it. If possible try using another cable or charger just to check.

Do the LED notification shine when you connect the charger?

I try check charger with voltmeter and was ok. Red led lights when charger is connected but now it's charging about 5 hours and stil can't turn on. This is new phone and it is first flat battery time.

Force restart the phone(power button+vol up until the phone vibrates) after 2 hours of charge.

Solved with another charger...don't know what is bad with original sony charger - after xperia is charged to 20% with htc charger, sony charger start work too, but don't work if xperia is totally discharged.

Still, you should take your phone to service and have it test another Xperia Z1 charger. Remember that USB chargers goes from 4.8 to 5.5 volts but they most likely have a diferent amperage and this could be messing up with your unit and untimately can damage your battery permanently.
