iPhone 5s will not turn on or charge
This iPhone was purchased and activated about 2 years ago and has had a screen replacement several months back. Two days ago, the device was left in a vehicle overnight. The device had been exposed to cold (<32 Fahrenheit) , but not moisture. After retrieving the phone, the battery had been depleted. While recharging the device, a series of colored lines flashed across the display before it went dark. After a few hours, there was still no change. I opened the phone to examine any possible damage, and saw none. After assuming it might have been battery failure, I replaced the battery with a brand new one. There is still no change. The battery warms slightly as if charging, but the screen is completely dark with no charging icon even after considerable charging time. Hopefully it is not Logic board damage. Any help would be appreciated.
Is this a good question?

I've seen this problem before, a quick and inconvenient fix is to charge a battery off of another iphone and put it in, the phone might work until the battery drains completely then it'll need externally charged again. However it's most likely a problem with the logic board, which will need replaced.

That is U2 Tristar Charging IC. If phone can't charge flat batteries.
