Sounding from your issues, it seems like you are a newcomer to the cellphone industry...so firstly congratulations on joining this money-sucking hobby.
Now as for your two problems.
1) I wish you would IN DETAIL list exactly what is happening. List which BT headset you are using.
What should happen is the following.
pair headset with phone. BT power remains on. When you turn on your headset (flip-boom style ones, this happens when you flip it out, non-flip out., usually have longer standby times so activated by just clicking button once) device will connect. You push button once, and voice dial prompt is initiated.
please explain WHERE in that process is your problem arising.
2) on-line listings for what the standby time is for the pebl is;
Battery Life Talk: 6.67 hours (400 minutes)
Standby: 250 hours (10.4 days)
Keep in mind, I'm assuming this is measured by not touching the phone, not allowing it to ring, or receive any calls, etc etc for the entire period. If you are that concerned with it's STANDBY time, then I suggest you test this out.
Otherwise, I'd be more interested in it's useage time. no BT, Just talk-time...how does it fare.
