I spend lot of time on the phone to my beloved Minx.
I sympathise with your plight which is only a smidgen worse than when the phone tells me the battery is running out which is a akin to having a 3 minute nuclear warning played down yer earhole.
Try buying 1 with more than 1 handset then you are sure to always have 1 at least that is charged. We have 3 handsets and find that rarely do we have any problems. Oh and the cost is pretty reasonable too.
