How Long Do I Charge A New Phone Battery. I show you how to maximize your overall iPhone battery life and how to get the most from years of battery use on iPhoneGear I used to make this video. The very first step we recommend is to read the manual from your phone manufacturer to see if they have mentioned any special instruction for charging your phone the first time.
Lithium Polymer batteries dont need to be charged before the first use because if the manufacturer that sold you your phone isnt stupid they will probably already be charged to about 60-70. BTW - the phone I just got was the Fusic by LG. After I do this it seems that the battery is so crappy.
Most suggest the 20 80 rule which you can definitely follow.
Unplug at battery level between 80 or lower and 100. Unlike the nickel batteries used in older phones lithium-ion batteries do best when kept above a 50 percent charge. When storing a battery be sure to partially charge it. Dont forget to use the included wall.
