Battery Low [Q] How do I disable auto power off when battery low?

I've got bit of a dodgy battery which for whatever reasons reports my phone being at 0% then the auto shutdown starts and the phone turns off.

The problem is that I can immediately turn the phone back on most of the time and have around 20% battery left and a few hours extra lifetime.

I'm not too bothered about data loss etc so I was wondering if there is a way of disabling this from the OS side.

My phone is the Xperia T. It's got a Snapdragon if there's something chipset specific for shutdown.
