Bluetooth and Wifi (not so much standard cell air connections) KILL batteries.
You can also get extended life batteries for most PDA/phone combos these days (except, of course, iPhone, which is hermetically sealed on Funk & Wagnall’s porch).
The other thing that will drin batteries quickly is when you’re in an area with no coverage (boonies) and your phone is searching for a signal. I just shut mine off until I get back in range.
For iphones 3 and 4 I used to have and for a droid phone I have now - having Blue Tooth ear piece on 24/7 - except when charging both - is not a battery drain for either one... I charge both units and I am good to go - for 8 hours or more ... I don’t use other forms of Blue Tooth connections so I do know about that.
Heh! Bluetooth headsets and a 6-month-old PALM smartphone?
Death to the phone in about an hour.....without use.
My iPhone? No issues at all.
My phone has a blue tooth sleep option
only draw back is that you can’t discover it when it is at sleep and it times out pretty quick once the screen dims due to inactivity.
Never had an LG, I have a Nokia .... rather plain but well perfected phone
