My wife's ipv Mini 2 has started to drain batteries very quickly. Under normal usage (which isn't very much for her), it drains a battery halfway through a nautilus Mini. Pop in a fresh battery at night before going to bed, and it's drained the next morning with no usage. Tried different atty/battery combos and it's all the same. Even compared it to my identical IPV and hers definitely has a problem. Has anybody run into this problem before? I'm waiting to hear back from the US vendor if they'll replace it (it's less than two months old).
