bought the wife a new jitterbug flip phone ,even if she does not use it ,it will drain the battery down to 30 or 50 percent every 12 hours ,so bought new battery ,same thing at first it uses 23% in 24 hours, a week later it too drains down to 30 to 50% in 12 hours , so we have to RECHARGE IT TWICE A DAY.we live in a big city so plenty of cell towers close byand spend days in another big city because of work ,and still the same thing ,does anyone know what causes this? her old style jitterbug phone only needed charged once a week ,this one is made by alcatel .
