In short, I just got my first BT headphones. Pairing them seems to be a pain in the ass. How much battery life does just leaving idle BT use for you guys?
I've read that it's not supposed to use much... Although my battery has definitely been draining faster than I would have expected on idle so far.
Am using trupjre 2.9

What's the issue with paring? I'm also using bt headphones and I just turn on buletooth, turn on my headphones and they are ready to go.

both are using battery constantly listening for new events. actually SyncSMS is most efficient since it uses Push Notifications to tell the other device when it should sync a new message
Are you referring to tethering? bluetooth uses less battery but i believe wifi is stronger

Bump this. Anymore opinions?
I would say Bluetooth, Wifi always drains my arc a lot quicker than Bluetooth does, when it's connected.
Just look at tethering, bluetooth uses a lot less power than wifi does
My SoT is 20 mins, media server has been running for 30 mins.
I have 3G, BT, WiFi , GPS and Google now on all the time. My S3 is able to get a constant 24 hours with the same use.
It seems that the nexus 4 idles OK, but plummets when anything is being used.
I'm using stock ROM, rooted with Franco kernel M1.
I've tried using better battery stats but it keeps resetting every time I open it, making it kinda useless.
Anyone have any idea why the media server uses so much or why its draining so quick?
Thanks

Having all those settings turned on will eat your battery. Are you using BT and GPS during this usage? If not, turn them off. Also regarding mediaserver, SoundCloud or other music streaming apps will engage mediaserver. When your done using said apps kill them from recents menu. Alternatively, you're rooted. I suggest you look into Greenify in the app store. you can select the apps to hibernate when not in use, it requires root.
Regarding BBS, look in settings, you may have something set up within the app thats making it reset.
Given that the battery is the same size as the s3, shouldn't it be able to keep up with it?
If I have to keep turning things off, it defeats the object for me.
I can't imagine the exynos being that much better. Like I said, an easy 24 hours with the s3 under the same usage with all the same things on.

You were listening to music via soundcloud so thats why media server is so high. Plus, you have GPS, Bluetooth and Google now enabled all the time! You answered your own question on why it's draining so fast.
If you don't need the services all the time, disable them until you need it.
It's the same as if you're wondering why your gas bill is so high when you leave the thermostat on at above 70 degrees Fahrenheit all winter long.

Thanks for the replies.
I do not understand why my s3 can do this without using half as much. Is it really that much better than a stock Google phone with the same size battery??
I use same soundcloud usage on my s3 every single morning on the commute and its usually at 89/90%. I'm ending up with 75 on the nexus 4.
If the nexus 4 battery life is rubbish, that's fine. I'm just looking for confirmation its not broken, which it appears not to be. I knew the S3 was better with battery, just wasn't expecting not being able to get through a day with the nexus 4.
Ive seen lots of pics of ridiculous SoT time, but I guess they must turn everything off.

Are you on 4.2.2? And how long have you had the phone?
Sent from my Nexus 4 using xda app-developers app
Hi. Yep on 4.2.2 and have been using the phone for a week.
Even with WiFi BT and GPS on this phone idles like a champ.
I'm convinced the drain isn't normal, 25 mins of sound cloud uses up more battery than the screen being on for over an hour.... Surely this cannot be right??
Its also worth noting that the phone gets quite hot - which I think is really odd seeing as all its doing is streaming audio.
I've attached some pics to demonstrate what I mean.
I really hope someone can help, I love this phone but if I cant get my normal day out of it on going to have to go back to the s3.
Thanks.

This may not be the phone for you, but here's what I do.
I have toggles (SwitchPro) for Wifi, BT, Data, GPS etc. that I push when I need them. I also have DS Battery Saver which helps shut down said items when screen is not in use.
I'm a Moderate user but I don't think you ever need to have all activities (GPS etc) activated when you are not using that particular activity.
With that being said, you control the battery and screen time. You just need to know how to manage it.
Hope that helps.......
Do you keep large media files on your phone? I've had mediaserver kick my battery's ass on that before if it can't for some reason properly index/understand a media file.
Use betterbatterystats or something equivalent to track your CPU usage and what frequency it's sat at most.
I used juice defender free, and got 1.9x savings. Bought the premium, and it worked for a while, now I get consistent battery drain, worse than before, it seems to have discharged idle down to 16% today.
I asked their support and they said read the faq!, which doesn't answer the question.
Does anyone have saved config settings for nexus 4 for
aggressive, extreme and custom they would like to share?
Juice Defender uses up far more battery than it "saves" and creates a ridiculous amount of instability on your phone. A guaranteed way to achieve significant improvement in your phone's battery life & stability is to uninstall Juice Defender, along with any task-killer apps you are running.
It's bad enough you got gypped into paying for it--but you may as well cut your losses here.

They haven't updated the app for years! I think they pretty much abandoned the project. So there's no support for newer devices. All they do is cut off connections when you don't need it. You can do that yourself.

Use Automate It instead. Takes a little more to set up but works flawlessly.
Sent from my Nexus 4 using xda premium
Yeah the app used to be good but it's rubbish now. Using it would actually drain more battery than it saves. You can see from the battery usage graph that every time the app turns on your data connection, it forces your phone into the awake state which wastes a lot of battery. You are better off leaving data on all the time.

IMO it was never any good--it interrupts system apps repeatedly which only caused them to "attempt" to start up over and over thereby consuming more battery than if Juice Def were never installed on the phone. It was like a task-killer on steroids; a pricey example of the placebo effect that does way more harm than good.
I can't seem to turn off the bluetooth and stopping from draining the battery. Help!
It seems that a bug in all G2 4.4.2 version. You have to live with it. However I dont see it affects much in battery consumption.

I've seen BT go nuts and actually drain my battery (25% battery drain per hour), but rebooting fixed it. Beginning to think that maybe JB is more stable right now.
I also get several random reboots everyday if I try to do to much at once.
Lol so LG has let out an update that basically ruins using earphones due to a hissing sound and this bluetooth bug which actually could also be a security concern. Nice work on their part... At least they mad the status bar icons white

It's a known bug on G2 4.4.2. They are supposedly working on a patch. I can attest that 4.2.2 is more stable. Being that one of the best things about our device is the awesome battery life, the fact that kitkat drains the battery is inexcusable. If the ROM wasn't done baking they shouldn't have released it. Some say it's false reporting. In my case it isn't. I went back to 4.2.2 and have zero issues.

Same here I have d801 and it says 6% is being used but its off
my phone is draining the same way
Even though I see Bluetooth listed, battery drain is actually better from 4.2.2, without doing a clean install of KK.
Factory reset fixed this for me.
I noticed this today, I never use bluetooth but have 5% battery drain. I can't say that battery life has got worse in KitKat, I still get the best part of 2 days use out of it. I'll try a factory reset, if that doesn't solve it I'll patiently wait for a fix.
The battery is the same if anything slightly better for me on kk

And i don't really hear a hissing noise in my headphones. So I'm having no bugs in kk. I love it, just can't wait for root

just a thought, to all those with draining, did you have apps disabled\services disabled whilst updating?
just guessing.

Correct - the 4-6% Bluetooth "usage" (it isn't draining the battery!) is a service called BlueSleep. It is merely being (poorly) reported in a manner that worries the masses. Expect an AOSP reporting fix sometime.
Lots of misguided hysteria around this...
(The 25% "drain" issue is poor wipe/flash regime.)
Hey guys, I also had a problem with huge battery drain with bluetooth. When I connected my phone per Bluetooth with speakers while charging, the battery needed for 50 % charging 9 hours.
I solved this issue by doing a factory reset in twrp.

Seems like turning on Bluetooth prevents the MXPE from going into deep sleep. I have not paired anything to my phone yet, I don't have Android Wear installed.
This is really frustrating. I had the exact same problem on the Oneplus One and a Moto 360, and I ended up selling both because it just wasn't worth the sub par battery life anymore. Now even the MXPE seems to be suffering from the same rubbish.
How do you tell if deep sleep is engaged?
Looks like I was having the same issue. Bluetooth was taking about 300mAh of my battery while it was on, but not connected to anything.
Not a problem for me. I leave it in at all times and I also use a Moto 360.
133mah over 14hrs
