Parani Bluetooth adaptors and high battery drain

Have you managed to do a full day, 8hrs+, with that phone? Assume Bluetooth and screen be on nearly all day but limited 4g data use.
Also curious if how strong you have found the Bluetooth connection to be, like when you walk behind something solid. For example yesterday was about 70m away from robot with Panasonic tablet but was a 1.8m fence in way so no line of sight between robot radio and tablet and it wouldn’t connect so had to get line of sight to connect and then move back to get the shot with it dropping out sometimes.
@350rocketmike I got over 300m range with the SD1000 connected to the RH16 radio handle on my old TPS1200, and about the same when using 2 SD1000 (one at the DC and the other one at the instrument) on the even older TPS1100. I have to mention that I was using high gain antennas at both ends.
I haven’t got quality time yet to do full testing… but just walking down the street 1000′ with a USB UD-100 & SD1000 I still got great reception…. and that was with the Stub antennas they come with it. (Haven’t tried the longer 5dbi antennas yet) Prob could have kept going.
Yeah, prob electromagnetic interference isn’t helping any. I.e. welding machines and just all kinds of other radio waves.
@lukenz I think my total time using the phone as a DC that day was about 2 hrs. I think I started over 90% charge and ended just above 70%, so no, I did not see a colossal battery drain using the Xpad, Bluetooth and the LTE. As a side note, the screen was switching off after 3 min.
@lukenz About obstructions, yes I had a few dump trucks and an excavator cutting my line of sight occasionally. The robot required the 360 prism every time. I kept it on tracking all that time and I could see the red laser pointing at the prism and the coordinates changing on the phone.
