Battery life of Phonak Marvel when streaming 4 to 6 hours a day

Rechargeable life is weak. Not enough for 24hours. When manufacturers said 1 day… they thinking of wearing time, that is 8 hour a day. This is weak very weak. Noadays you stay at the zn-air and wait for the time when the rechargeables’ running time is equal with zn-air batteries but at least 7 days with 6 hours transmitting on bt, every day.
