Quick question regarding tethering and battery life

[Mix1]

So as the title eludes to, this is about tethering my iPad 2 to my iphone via bluetooth. As such my bluetooth is almost always on, it is the main way I access the internet on my ipad.

So what i wanted to know here has this method been subject to reports of a decrease in general battery life when compared to being connected via wi-fi? I say this because my battery seems to drain pretty quickly. Although i could be being paranoid.

Can anyone shed some light on this? Thanks in advance.

your post is kinda confusing..
are you asking if your iphone will drain more battery when set to hotspot, with bluetooth? vs wifi on??
or are you asking does your ipad drain quicker, when you turn bluetooth on to tether, vs connecting via wifi?

bluetooth drains much quicker than using wifi.


when i use my bluetooth to stream spotify to my car. it lasts 3-4 hours maybe. and thats with the screen off.
just leaving bluetooth on and inactive, drains your battery quicker.

bluetooth drains much quicker than using wifi.

you sure about this? i'm pretty sure bluetooth power consumption is way less than wifi. especially while tethering.

speeds will be slower on bluetooh tethering vs. wifi tethering though.

nope not sure, it just seems on my phone bluetooth drains more battery.


maybe i think that just due to bluetooth having slower data speeds, so i need to use it longer to download files. as opposed to wifi tether

shows that bluetooth drained slower by 1%

i just think it appears to drain worse, because i have to leave the radio on much longer than wifi.
