New battery fitted. Fully charged now and looking good. The real test will if it can stay on standby all night and still have battery life in the morning.
Morning has broken, like the first morning…iPhone has spoken, like the first phone. It’s on. Hooray! So all the problems have been solved with the new battery of the RIGHT type, not the incorrect type that I tried to use and that was in the phone when I purchased it off eBay. I have made several calls with my iPhone and it is all looking good. One problem, no camera. The shutter stays shut and it won’t take a picture. I think I must have damaged it when I replaced the battery so will have to order and new one and hope that does it. Perhaps I can get a higher res one.
