Looking at the macfag modding iphones to make them less shit (eg: audio jack) is it possible to add an extra battery? I remember some guys changing the battery on the nexus 5 for a bigger one from another LG phone that was compatible, though it took tons of work and they had to replace some circuitry.
So I was thinking about instead getting an extra OEM battery and connect it to the original, getting 2 batteries on the phone. Any EE fags here? would this work or it would short-circuit and destroy my phone?
