Full Answer. Lithium batteries have a longer shelf life than alkaline batteries. Rechargeable batteries are also available. With normal recharging, they can last up to 10 years under normal use. Rechargeable batteries are recommended for devices that are used on a consistent basis, such as game controllers.
The real killers of lithium batteries(the kind in your phone), is heat & frequent full discharge/recharge cycles. They have a design life of 3 ~ 5 years, & will last much longer if not subjected to frequent discharge cycles below 40% of capacity. Apple recommends you let your battery fully discharge/recharge once a month...every couple of months will be just fine. So, to maximize your battery life, charge your phone as often as possible & avoid high heat.
