I am excited to upgrade to a Google device and not deal with locked bootloaders. It is my understanding that the process used to avoid the locked bootloader in my Droid X may have something to do with the short battery life of custom ROMs.
Yet, I am curious if all custom ROMs would perform poorly battery-wise because typically they are based off of AOSP or AOKP and therefore don't have the tweaks the phone manufacturer made to Android specific to that device?
In other words, if I bought a Galaxy Nexus and installed a custom ROM, battery life would be...
I suppose it is a dumb question and the real answer is 'it depends on the ROM.'
I just burned through my battery today in a little over 5 hours.
