Why won't my phone turn on?

One day, my battery drained and my phone was completely dead. I tried to charge it, it was charging, but wont turn on (even after charging it overnight). It's not because of the charger, the charger works fine on any other devices like my iPad. Its been like this for 4 days now. Please help me, thank you.

U2 Tristar Charging IC gone bad. They go bad due to aftermarket / copy non-MFI certified charging cables and especially when bundled together with car chargers.

You will need to find a board level microsoldering technician to get them to replace that chip. A regular person can't do it.

Sometimes it is the charge port too, and sometimes the battery; though the above is most likely.

Rule it out or have a repair shop rule it out if you're not going to invest in parts only to find out it is indeed the U2 chip.
