Are you trying an original samsung battery.
Also its worth trying another original samsung charger.
If you get stuck then look to see if there is a Samsung Service Centre near you or approach the seller of the phone if obtained via a shop.
A 24 month manufacturing warranty is placed on the phone.
Hi thanks for your advice. The phone is older than 2 years so not covered by warranty. The new battery is an original Samsung so I guess maybe the phone has come to the end of its serviceable life!
Thanks again :-)
You're very welcome.
It then really boils down to how much time and costs you want to invest in the phone.
