@Flohack Thanks for the insights. The reason does sound logical. But if that is the case, why does bootloader allows the phone to go to recovery and stay there? Shouldn't bootloader stop from phone going into recovery?
I am not questioning your knowledge, just a bit more curious about how it works?
Also, can you guide me on how I can debug\identify if that is the real issue?
@Flohack I ended up replacing the battery and it seems to be working fine.
The surprising thing is, I had replaced my old battery 4 years back. Now that is not working, but the original one that I had kept as spare, is working fine. 
@poVoq said in Nexus 5: Hammerhead: Ubuntu Touch boots only when connected to power source:
Most likely a battery issue. The Nexus5 is old now, and didn't have a strong battery to begin with.
I bought a second hand Nexus5 with similar issues (on Android) and after installing a new battery it was gone (and works well with UT also).Replacing the battery is quite easy, so just get a new one
Replacing the battery worked.
@Flohack Also pulled /cache/recovery/last_kmsg.

@Flohack Thanks for the insights. The reason does sound logical. But if that is the case, why does bootloader allows the phone to go to recovery and stay there? Shouldn't bootloader stop from phone going into recovery?
I am not questioning your knowledge, just a bit more curious about how it works?
Also, can you guide me on how I can debug\identify if that is the real issue?
@AppLee May be I'll try to get the battery down few percent and try to boot again. Let's see if it works then.
@poVoq Hmm could be. but the battery worked good with Android. I was running Android P on it and it gave me a good backup.
@Lakotaubp Thanks. I did try that as well. Reflashed device when it was fully charged, but sadly no luck.
Thanks for the suggestions though.
@Lakotaubp Thanks for the response, but as mentioned, my phone never goes into bootloop. It just switches off. Also, if I switch on my phone in bootloader\fasboot, it stays and does not restart.
I did a successful flash to Ubuntu Touch for my Nexus 5. from Mac via ubports-installer The issue that I am facing is the phone only boots up when it is connected to charger. As soon as I remove the charger, it just switches off.
If I try to boot without being connected to charger it just shows initial 'Nexus 5, Powered by Ubuntu' Screen and then switch off.
I can stay in fastboot and bootloader screens for as much time as I can (tried keeping it for an hour), so I don't think it is a battery or hardware problem.
Also, Android P was working all fine before in installed Ubuntu Touch.
Any suggestions on how can I fix this?
