I have had my Nokia phone for approx. 1.5 years. It has been working wonderfully well then, about 2 weeks ago it suddenly stopped holding a charge for longer than 4hrs. It charges fine but in 4hrs. or less is completely dead. I purchased a new battery thinking that was the problem but that hasn't made a difference.
I am sorry to hear your phone isn't holding a charge. I know how much I rely on my phone so let's add some life to your battery. Is your software up to date? How do you typically use your phone? Please share details.
