[Q] Nexus 4 won’t boot up/work without charger plugged in after flashing topic

I have flashed a CM12 nightly using TWRP recovery. After that, during rebooting, phone switched off automatically after showing “google” logo. I went back to the TWRP and installed the backup which I have kept (stock lollipop 5.0.1). After that when I’m trying to turn on, it’s working with the charger plugged in. If I remove the charger after switching on, if I kept it idle, it will stay on till the battery is empty (I got around 24 hrs). But if I try to take mobile data or camera it will switch off for sure. Sometimes just moving across different home screens also will make it switch off. The battery status show is also not correct when switched on. In recovery mode it works well without battery and battery percentage is also correct.
What will be the reason?? Is it something related to the firmware or a Hardware issue?? Will changing the battery help??
