What consumes more battery Data or WIFI? what about Bluetooth?
- BT definitely does consume a LOT. It's always on and it's always seeking for devices it can connect to. I leave wifi on almost all the time and do pretty okay with it.03-02-2014 11:57 PMLike 0
- Data should be the biggest battery drainer among the three. Wifi can greatly increase it's consumption depending on the device you connect to, but when it's not connected, it should consume relatively little energy. Can't tell about bluetooth, i never leave it on when i don't need it03-03-2014 07:49 PMLike 0
- Same here. I got tired of constantly toggling wifi, Bluetooth, and cellular data on/off all the time and worrying over my battery life. I just leave all 3 on now and I don't notice much of a difference.

- In general, power consumption on any non-wired connection is dependent on the strength and quality of the wireless signal. But 3G/4G data is often perceived to be the power hog because the signal strength varies so much from area to area and the radio ramps up power to compensate. This is less of an issue with wifi or Bluetooth.
Personally, I'm in the 'leave 'em all on' camp unless I've got a specific reason to turn one or more off.- Share

- Cellular Data is usually the biggest consumer by far. It will vary though depending on the signal strength you phone is seeing. I am in the leave all 3 on camp unless I am roaming.03-04-2014 01:20 PMLike 0
- 4G wireless data is a huge power drain compared to 2G or wifi. Can't speak experientially to BT.

There are many threads where users ask for a 3G/4G toggle to stay on EDGE when not necessary and it's a very valid point. Especially for T-Mobile users since their coverage is so spotty.03-05-2014 08:00 PMLike 0 - For me its def WIFI when i get home from work and connect to mine after watching a good few vines, checking twitter, facebook etc couple of txts and whatsapps my phone battery can drain awful quick lol i use a 925.03-06-2014 08:04 AMLike 0
- fatclue_98Retired ModeratorYou're saying cellular connections drain batteries faster than WiFi? That makes no sense. WiFi is for data only, which means you're still using cellular for voice and texts. I'm not an engineer but I know that 2 radios consume more resources than 1.03-06-2014 10:35 AMLike 0

Read what OP said. He watch online video on Vine. If you watch video on 4G or 3G connection instead of wifi, you may use more battery juice. Try it and you shall see. Your voice cellular radio is always there. The only difference here is which radio you use for large amount of data transfer.
And in case you haven't bother to read earlier posts, on idle, they don't make much of difference whether you have wifi on or not.03-06-2014 12:27 PMLike 0 - I think it depends a lot on how built out the 4G/LTE network is. My provider in Canada (Bell) has been building out LTE like crazy. I don't really see any difference between it and 3G. I get around 2 days with my Ativ S between charges. I am not a power user though.03-06-2014 03:07 PMLike 0

I've gotten tired of toggling wifi/data/gps all the time a long time ago. I carry an external battery pack so I can use the smart in smartphone without worries.
I know though, that staying at home uses less battery then commuting, because constantly switching towers while on the road eats more juice then solid and stable network (both cell and wifi) at home.
I've tried toggling 3G/4G (since I have LTE limited to 20mbps it makes no difference - I'd have to pay 6€/month for full speed LTE) and I don't notice much difference in battery life. Maybe like 30 minutes at the end of the day.
In other words, I haven't had my 925 die on me (so far)03-06-2014 03:20 PMLike 0 - There is also a difference in 3G vs 4G power consumption depending on the chipset in the phone. When 3G first came out the 3G radio was separate to the the System-on-Chip that ran the voice and 2G comms. Gradually the 3G functions were integrated into the SoC, so the difference in power consumption between 2G and 3G became less, and is minimal on the latest phones. Same is happening now with 4G. Most phones run a separate 4G chip at the moment, but these functions will gradually be integrated into the SoC.03-06-2014 04:37 PMLike 0

As Marty Larsson has highlighted, though, many people have limited cellular data limits but much higher or unlimited WiFi quotas. Therefore they don't use data as much on cellular as they do when they are connected to WiFi. So the battery gets more of a hammering on WiFi - but not because it's less power efficient, simply because the phone in general is doing more work (screen on, processor working hard, etc.).03-06-2014 04:48 PMLike 0 - Ditto. Always leave 'em on, and still get 20 hours of battery life from my 1020, minimum. Really convenient, too, for when I need to use my phone as a hotspot for my SP2. Just go into my available connections, tap my phone, and it automatically sends a signal via Bluetooth for my phone to set up hotspot.03-06-2014 04:52 PMLike 0

The GSM radio can be toggled off and use BT or WiFi exclusively. If you had read one of MY earlier posts you would know that 3g/4G/LTE will consume a lot of power if it has to hunt for a signal because of spotty coverage. GSM power consumption has everything to do with strength of signal so what works for you or me, may not apply to the next guy.03-06-2014 05:54 PMLike 0
- 1. BT -> sucks the life out of your device before you could boot it
2. Data Connection -> compared to Wifi it also sucks quite a bit
3. Wifi ->lowest battery consumer out of the three
Also Background Tasks can suck life out of the battery.
Minimize those background tasks-<.m.03-06-2014 07:12 PMLike 0 - 1. BT -> sucks the life out of your device before you could boot it

Otherwise, it's impact on my 1020's battery is minimal to nonexistent. I like to leave it on so I easily pair my phone with my BT speaker, without any hassle or set up.03-08-2014 08:29 AMLike 0 - This question's answer depends on the state of the particular connection you are talking about, as in Active, Passive and Off.
Active means that data transfer is occurring, Passive means that the radio is switched on, Off means the radio is off.
Active: Bluetooth > 4G (LTE) > WiFi > 3G and 2G
Passive: Bluetooth > 4G (LTE) > 3G and 2G > WiFi
In the active state, bluetooth keeps looking for devices to connect to and broadcasts a bluetooth signal to allow other devices to discover it. The latter is one of the greatest causes of battery drain apart from actual data transfer. To prevent it, you should turn off "Visibility/Discovery" which is something not available on all devices.
The battery consumption from any cellular connection depends a lot on the signal stability and strength, so prefer 3G and 2G over LTE because as of now LTE doesn't have a great network.
WiFi in the active state doesn't consume too much power as the data transfers are completed in a shorted period of time and the radio remains idle for more time than compared to cellular connections.
In the passive state, bluetooth searches for discoverable devices making it drain too much battery. WiFi when idle has no network activity and hence the radio 'sleeps' to allow for power savings. (PS: Allowing your device to automatically discover hotspots will drain a lot of juice as it requires the WiFi radio to both transmit and receive WiFi signals.)
I hope I have solved your problems.03-08-2014 11:23 PMLike 0 - In the active state, bluetooth keeps looking for devices to connect to and broadcasts a bluetooth signal to allow other devices to discover it.

Also, aren't there different versions of Bluetooth that use power differently? And if so, do any of them change the hierarchy you listed?
