Check with another battery. if still it does not turn on, then there is problem with your power IC. you need to replace it.

Ok hopefully it works 4 u.
I cleared all calls incoming,outgoing,missed. then i cleared all call timers, made call times ,uncoming timers, all of them. i turned off my phone went to bed with it off and on the charger. woke up the next morning turned it on and car kit was'nt there the phone rang. WOW! IT WORKED!!! GoodLuck!!!

try to go to a local store or through your service provider to run a test on the battery that you are using. It might be defective, tyr using a different battery for the phone. If using a different battery would not resolve this issue, it means that the phone needs service.

You should not allow the battery to fully drain,it will die sooner.

Remove the battery for 5mins, replace,and then try and turn on the phone.

Thats what my phone does when the battery is dead. perhaps it did not charge last night. see if the phone will turn on while connected to the charger. if so, the battery is dead or defective.

your phone firmware need to be reflash and if that does not work then you may need to purchase a new mobile phone.

replace cell battery with new one
