I'd try a new battery and then consider swapping it out. These models didn't seem to get much past 2 years old and if the battery is over a year old, I don't think twice about replacing the battery when it's suspect.
There are folk that don't want to try. For those you advise them to replace the phone.
Hi.I have a NOKIA 610.Suddenly where we worked was closed it alone.When I connect the charger does not opens the screen,only flashing the windows logo 10 times or 5 times.I tried to hard reset but I do nothing.The battery, while saying is 3,7 V but as long as and I leave the charger to the phone,I count constantly 2,8 V.Are these battery problem or something else?Thank's!
