I have an SMH3 and find myself in the situation where I get a warning of battery low and a minute later the device switches off.

I use my SMH3 every day and even though I charge them often my use per day and week vary's in time so a voice notification will come in very handy as I can not afford to have calls drop on me or not receive calls as a result.

I also use a phone GPS and I prefer not getting half way and then not knowing where next as a result of a low battery.

Please, Please, Please add this.....
