My phone is stuck in the boot loop, restarting every 2-3 seconds

Hi,
I am having an issue with my Htc One M7. It is not turning on, no battery charge though. But when i try charging the phone instead of charging, it keeps on restarting, shows the boot logo animation, and in 2-3 seconds it restart again. Even a hard reset doesn't help. it goes to the reset menu, but the same doesn't last. In two seconds it goes back to black screen and restarting. Can it be a battery problem?

Probably. When's the last time you've changed the battery? J/K
I now you need to go to a dealer to do that.
My M8 is getting kind of drainy too.

You were able to power it up long enough to do a factory reset?

It's possible that the battery has died so completely that it cannot boot, i.e. the battery can't supply enough current and the phone crashes while trying to load the OS. But if it's happening that quickly I'm surprised it could boot into recovery mode and carry out a reset. But if you have managed a reset and it does this that doesn't leave many other possibilities: battery failure, or some other hardware failure, or corruption of the system software (possibly due to a failure of part of the storage). Hard to say much just from the fact that it's looping.

Try charging it for a while, make sure it's cool, then try again and hope is all I can think of.

It can go in to recovery mode. But it doesn't give me time to even select the recovery/reset option. Even the charging is of no use. It takes all the power to continue with the booting, and not seem to store in the battery. So, even a 5 hour charging is not going to give anything.

OK, so if it also crashes in recovery mode then you won't be able to factory reset it, but also a reset wouldn't help. A reset will fix a bootloop if that's due to bad/corrupt/incompatible data, but those data are not read when booting into recovery (which is a standalone module independent of the Android software). So if it's crashing in recovery, I don't think a reset would help it.

It also rules out corrupted system software: again, recovery is independent of the Android software, and indeed its whole point is that you can use it when you can't run Android. So if it's crashing in both modes then it's not software.

So that leaves hardware, either battery or some motherboard issue. I'm sorry, but I don't think there's anything you can do here: it's either repair or replace, and replace is probably cheaper.
