(Not sure if there is a DIY Section, Mods please move if so) I kill my battery very quick everyday. Mostly because I do around 1,000-3,000 texts a month (Girlfriend goes to school 4 hours away). I don't feel like paying $30 for some 'Energizer Charger' and have seen many homemade chargers. Has anyone made one for their Droid? My design so far: - 9v Battery - 5v Regulator - Altoids Tin - Simple Switch - LED w/ Resistor So idk, I am afraid of a power surge or other thing that could fry my phone. I am assuming 5v is the charging level since that is what a USB is pushing. Any input would be appreciated, Thanks!
