Battery drain caused by Bluetooth - Verizon Samsung Galaxy S7 Edge Questions & Answers

Battery usage shows abnormally high for bluetooth. I had no problem with a tmobile S6.
I have a LG G Watch and have bluetooth enabled all the time. I'm seeing BT using more power than the screen on time. Anyone else have this problem?

I have a moto 360 sport. Bluetooth is never hough on the list. I know on other phones some times it would show excessive Bluetooth battery user, but a reset and re-pairing of the watch usually fixed it.

Found it was caused by having scan nearby devices enabled (by default). After I turned off that, no more abnormal power usage from bluetooth.
I disabled following:
Settings - More - Nearby Device Scanning
Edit: Now it's back. Bluetooth is 3rd highest power hog on my phone. Android System 50%, Android OS 21%, Bluetooth 18%, Screen 3%, ...
Sucks.

[Q] Wifi staying connected

Recently my note 3's wifi won't turn off while asleep. Under battery usage it shows that the wifi is on the entire time. The android os also shows as being on for more than an hour (it's also the top app on battery usage). It's lead to a battery drain. Using wake lock detector and bbs I haven't seen any app that is causing the problem. I haven't changed any setting either. The wifi is set to never be on during sleep periods. I remember seeing a post with a problem about this but I can't seem to find it anymore. I really don't feel like resetting back to factory settings. Anyone experience this or know what's causing it.

LG G2 bluetooth battery drain!

Hello guys, I updated LG G2 to KitKat yesterday (V20-march06-2014). And bluetooth seems to be going crazy! It's next only to 'Screen' in battery usage. Comparing to bluetooth, WiFi consumption is almost neglible (0-1% ) vs 9-15% of bluetooth and 23-30% of screen..
Is there any fix or patch for this? Any temporary fix? Battery life was so awesome before 8+ hours screen on time! Now it's down to 4-4.5hours. Standby time is also affected. Disappointed!
Unable to find a fix on via Google search.
Bluetooth is reporting incorrectly, and does not actually use more power. If you're down to 50% power loss, you should be looking into wake lock detectors.

Could you please recommend me a wakelock detector app that works without root?
Well I was using my phone continuously like before but this time it's using more power than before (at least 20-40% more power). I'm doing the same tasks (xda app, little web browsing,YouTube)
So I do you think it might be wakelock issue when my tasks are in awake mode?
Thanks!

[Q] Android Wear App draning battery

Ever since I downloaded the app and paired my phone with my LG G Watch, I went from a full day's use to only 6 hours on my Oppo Find 7a. Its really frustrating. Tried resetting, redownloading and reinstalling to no avail. My phone even heats up now (something it doesn't normally do). I know with bluetooth and constant connection with the watch, battery life will take a hit but never expected it to be this much. Any one else?

As you said, bluetooth and constant connection would drain the battery life...

Not necessarily... I noticed only slight more battery drain running it on my S4

bluetooth's problem
Oppo Find 7a must be defective, bluetooth takes very little battery life. I am thinking up until you had a bluetooth device you never turned it on, you finally turn it on and find the phone is defective.
My Note 3, I never turn off bluetooth off and I can not notice any battery drain.
Looked at the screen shop Android Wear is in some sort of wake lock.
Mine Android Wear is not even listed see Bluetooth at 3% but no Android wear.
You have some utility that maybe cause issue? I never use a battery conserving app they do not work.
or the device which I do not know may not be using 4.4?

Android Wear's Horrible Drain on Battery

Android Wear with my Moto 360 is consistently killing my T-Mobile Xperia Z3's battery life every day. Yesterday it used over 35% of the total battery, topping out Screen-On time in the battery listings. This morning it has already killed 28% and its barely 11AM.
Is anyone else experiencing the same issue? Its making my Z3 die way earlier than it should and its ruining my Z3 experience.
I had the same issue when I first setup my lg android wear watch. The following resolved my issues.
Don't use stamina mode - personally I get worse battery life with it enabled.
Uninstalled android wear app with watch still paired then reinstalled.
After both those steps my android wear app uses next to no battery.
Hth
I don't have this issue, I just did a normal install and pairing. I also have the 360, and its pretty much paired all day.
my smartwatch 3 has been dispatched, so Ill report what it's impact on battery is like shortly

Same here.
No real effect on battery for my gear live
I was having the same problem with the Android Wear app causing major battery drain, but it would only happen at my office when on corp wifi. When I would turn off wifi, usage would drop back to normal levels. I have very limited notifications going to the watch.
How was I measuring this? My 'normal' battery drain is 165mA (measured using Battery Monitor Widget Pro). When the problem was happening, my usage would go to 665mA and I would burn through the battery pretty fast.
I had tried to reset the watch.... no change.
I tried reseting and not reloading apps... no change.
A couple of days ago though, I uninstalled the Android Wear app itself from my phone and then reloaded it and set everything back to the way it was prior to deleting the app. I'm a little surprised to report that it seems to have cleared the issue. My battery usage is now back in the 165mA range where it used to be. I'm crossing my fingers that this holds up!
I got a G watch and it did not affected the battery life. I guess trough the day I spent around 5% more juice from my Z3
There is a known issue with some corporate WiFi networks (and possibly other secure locations). For security, a lot of places will block all DNS traffic not going to the internal servers. If this is the case at your work, the Android Wear app is constantly trying to connect to the Google DNS servers and failing. The app should fall back onto the DHCP assigned DNS servers, but it doesn't do that. An easy fix is to turn off WiFi. I usually have to reboot the phone to stop the drain.
I had this issue at first as well, but after a bit of resetting and repairing, the watch barely uses any battery. I leave the Stamina mode on and even after moderate to heavy use and 10 hours of being off the charger, I still have about 50 percent left at the end of a work day.
I was having heavy battery drain only with stamina mode enabled. I allowed android wear app to run in stamina mode and usage is is now not even taking 1%
Use a Moto 360 with mine, lots of email and chat notifications all day for work. 9 hours into my day i'm at 66% battery.
I too had that issues
I have a 360 & t-mobile z3. Both batteries are draining extremely fast. Android system seams to be the problem. I've tried force stops and clearing data. I may have to reset both devices. Any thoughts?
I had this same issue with my Z3c and now my Z3, turning off stamina mode solved this for me!

Same combo for me, never had a problem with battery life. I returned the Z3 because of the camera but I miss that mofo. Now I'm back on my N5 which does not have great battery life to say the least.

I ended up having to reset both devices and start fresh. Back to great battery life on both devices. Now if I could just figure out the why....

Android wear app is not even listed, but my phone never get to deep sleep and battery life is worse.

Style Mod heat issues?

Ever since I got the device, I've noticed that whenever I get bored and put the wood stylemod on that came with the device, even in standby, man this thing heats up a lot. Anyone else have this issue?
I have seen this in other forums. Do you have Gsam Battery monitor installed? My bet is theres an app running in the background. Gsam can tell you what apps are running.
Try leaving bluetooth and wifi off when not in use, turn off bluetooth in location settings, not sure if it would help but I did that day one, always have the style mod on when not connected to the speaker, only time I notice heat is while charging and casting fpse to chromecast.
Mines having no issue at all, and i always have wifi Bluetooth on
