I have replaced the screen and battery in my iPhone 5c and the device will not power on I have tried to hard reset the device leaving it to charge and still nothing before I replaced the screen and battery in the phone. it worked great until idroped the device and the touch screen stopped workings of I replaced the screen I left it in my draw for about a week and after that the device will not power o and device will not power on so I replaced the battery and the device will not power on at all

Check the batteries voltaje (both de new and the old) to be sure that they are at least charged. If the batteries have at least 3.5v leave the phone charging by 30 minutes, and check again, if you got the same lecture or less the issues is in the charger port. Also if you have an external power supply charge you battery until they are in 3.9v o above and try again to turn your phone on.
