Phone won't boot or charge if it's power off

Its the third time this happened with me that i for to py my phone on charge and the battery dies that's not the issue but the problem is that when i wake up and my phone on charge with the drained battery. So i plug in the charger and phone won't charge and it won't boot(power on). So i have to go in download mode and restart my phone from the download mode and then it will boot and charge. Just now i checked my battery is 60% and i switched off my phone and it charges while its off.
