I have rechargeable hearing aids from Boots. Everything was fine until the software was updated last October. Now the batteries run out after about 14 hours or less if I have used the Bluetooth phone connection for a while. Although that is fine 90% of the time, it is sometimes a problem. So I contacted Boots head office who said that should not be the case. I booked an appointment with our local branch, explained the problem but also said that I could not manage without them for the two weeks it would take to fix them. The audiologists said that was not a problem as they could loan me a pair and booked an appointment a month later when the loan pair would be available. I have just attended that appointment to find the previous audiologist had moved on and there were no loan hearing aids.
