[Q] power consumption: Bluetooth vs WIFI tether? - Xoom General

looking for some real world insight. looking at getting the WIFI only xoom, and tethering to my milestone, but am hearing issues with high battery consumption on the phone.
Bluetooth is supposed to be more friendly to the battery than WIFI, are you experiencing longer runtimes on Bluetooth vs WIFI tether?
if so how much approx? ~10%, 25% 50%??????????
Thanks

BT Dongle sync'ing

Just wanted to mention that I am sync'ing and surfing with a BT dongle on my desktop computer over my iMATE. It works great with no problems holding connections.
Excellent
It is great isn't it! :lol:
yes it is and its stable and flawless not dropping any connections. The speed it quite good too and I don't find battery usage poor at all ... surfed for about an hour with only a couple percent drop in power.

Bluetooth reduces Touch HD battery life dramatically

I just last month purchased a Touch HD (Blackstone) which I've really enjoyed. And I paired it with my Bluetooth headset (Jabra BT5010) which was used to pair with my HTC p3300 Artemis.
Last month, every day my Blackstone’s battery life is just 10~12 hours between charging, even with no call and other usage. I thought maybe 3.8’ screen have drained much power.
Last morning, I happened to turn off Bluetooth function of Blackstone after a full charge. Then I find there is still 62% battery life remaining after 24 hours with average usage. That means the battery life could last for 3 days without Bluetooth turned on.
For sure, Bluetooth drains much power from my handset. But also I don't want to toggle the Bluetooth setting on/off every time I want to use Bluetooth headset? That would significantly cut into the convenience of this item. Is there some advice or is something my Blackstone misconfigured?
PS:
My Touch HD: Rom 1.57.831.1 (47324) WWE, Rom date 04/08/09. CE OS 5.2.20776 build 20776.1.4.9, radio 1.14.25.24, protocol 52.64.25.34U, Bluetooth 2.0/2.0+EDR
My Bluetooth headset: Jabra BT5010.
Bluetooth software: btIO v0.6
You can try to disable beam if you didn't already.
I keep BT always on and with average use my battery lasts about 2 days. I tried several cooked ROMs and battery life seems the same.

Do you mean go to start->settings->connections->beam, and uncheck "Receive all incoming beams."? I've disabled that, but the power is still leaking dramatically.
In "comm manager", there is no item about beam.
(just 7 items I have as following
Airplane Mode: off
Phone: on
Bluetooth: on
Wi-Fi: off
Microsoft Direct Push: off
Data Connection: off
3G: off)
Do anybody have any advice?
Thanks in advance

Alternate: Bluetooth on, WiFi off

I was hoping for a mod or app that would alternate Bluetooth & WiFi because I only ever need one at a time and want to save power! Eg: I leave the house, my WiFi signal is lost as I move away from router, so WiFi turns off and Bluetooth turns on - as I would be leaving in my car and use BT handsfree... then, when BT connection is lost after engine is, turned off... you have an option to have WiFi switch back on! (or not!)
Anyone heard of such a thing, or know how to create it as a profile?
Thanks!

I use Battery Saver for WIFI control and TASKER for (1)bluetooth on (2)screen always on (3)max brightness when phone on charge in the car (for me I need bluetooth off the moment I get out of the car as I use speakerphone. When I''m in a customers home I don't want phone still connected to car).
Battery Saver, like many other apps (inculding TASKER itself), uses cell phone positioning rather than GPS to determine where the rememebered wifi point is. It will turn it on when in range. TASKER and bluetooth control is very basic, based on USB/AC charge.
For me, what you want is achieved flawlessly with the above 2 apps. TASKER is an excellent app, with the potential to do far more than the bluetooth control I use it for.
Cheers mate! I'll give them a go!

You can use Locale for that and for so much more.
My locale is set-up as to when i enter my house it detects which cell tower i'm locked on to and enables wifi and autosync, if the battery is higher than 20% and i'm in the 8:00am-01:00am schedule.
Use widgets? Does it for me. Go into settings if you do in Widgets or use the Power Control

Solution: ICS Unstable wifi tethering with Macbook air

I encountered unstable Wifi tethering with my macbook air since I started using misc. ICS ROMs. The IP communication is lost and I need to disable and re-enable wifi on the macbook to continue communication.
After fighting this bug for months, I believe I have found the cause and a workaround solution:
I believe the problem is caused by putting the Android phone too close to the macbook air. Apparently the transmit level is too high.
Putting the phone at least 1 meter away from the macbook seems to solve the problem.
I travel 2 hours/day on the train with tethering on. I need to put the phone behind my back to have a stable connections.
Personally, I've never had an issue tethering my Macbook Air to my Note.
Then again, I'm using Bluetooth tethering anyway.....
Why not try that instead?
Regards,
Dave
bluetooth ? alternative ?

Thanks,
I used bluetooth for some time but this had some other disadvantages (I cant remember - slower? interruptions in the music on my bluetooth headset? - more battery use ? )

I've not had a speed issue myself, and I believe that BT tethering should always use less battery than WiFi.
Whilst I do frequently used BT headphones, I never do so whilst tethered.

This is exactly what happens with my Verizon Galaxy S3 with CM10 and my MacBook Air.
I will try your solution and see if it helps...
Thanks for posting your findings!
I also found by setting the MTU size to 1453 seemed to help.

[Q] nexus 7 - GPS and BT Tether?

Hey guys,
I see that the nexus 7 play store says it has GPS. Is it similar to the real gps that we get in phones or will it work with wifi signals only?
Jelly Bean supports offline maps, so is it possible that I can save a city offline and use it beyond the range of the wifi?
Also, Will BT tether work with this device? I have a Nokia E5, but with a joikuspot wifi hotspot, battery drains in 3-4 hours..is it possible to connect the nokia and the nexus 7 through bluetooth?
I believe the answers are:
"Real" GPS, not just WiFi triangulation per the spec sheet
HTML:
http://www.google.com/nexus/#/7/specs
Yes, offline maps will work offline...
If BT Tether works with other Android tablets there's no reason to think it wouldn't on JB/Nexus 7. Maybe someone who tried it can confirm.
Bluetooth tether DOES work! I saw it with my own eyes last night.
