iPhone 3gs battery life
I have had my iPhone 3gs now for 3 months, suddenly I am starting to know that the battery life on the iPhone 3gs is not good at all. How do I fix the battery life on the iPhone 3gs. I used to charge the iPhone 3gs one time per day but now I am charging the phone up to two times per day maybe three times per day as well. Is the battery charging considered normal or am I causing damage to the phone. I am open to any suggestions that fellow members of the Apple communities might have for me in regards to the iPhone 3gs. I really would like to fix this phone if I can. Thanks
iPhone 3GS, iOS 6.1.6
