I have a Nexus 4 for about a year, and until the last 2 months I had no problems at all. I started noticing my phone shut down after about an hour because of my battery swelling. I replaced the battery and I had great battery life for about 2 days, after that it drained super fast.
A few times my phone shut down and a red LED started blinking, I fixed it thanks to a thread in this forum.
But now, I had 100% battery and it turned town. I tried to start the phone but nothing happened. Connected the charger and pressed the power button a long time until a red LED showed but for a long time.
The blinking LED didn't worry me because I knew my battery drained and it fixed but now the battery is full, the LED lasts for long time and no matter what I do, nothing turns on the phone.
I don't know what to do and I'm really close to throw it away.
