You should check you PA, does it get "very" hot during a call or during stanby ? If so change it.
Second option would be to look a the power module (N700), located to the left lower part from the PA. Check the following voltages around it ( use service manual to find the components )
1 : VBOOST 4.75 V @ C503
2 : VRAD 3,8 V @ C500
3 : VCORE 2.5 V @ C702
4 : VDIG 2.8 V @ C703
Also you would like to check the resistance of the battery connector, if you have around 15 to 25 Ohm, then your power module is for sure faulty, and will have to be changed.

For first try recharge Youre battery fue time! from zero to full. New bat need feu recharge befor it do to max condition.
