I received and installed the 5.1.1. update to my Canadian Note 4 last week. Immediately I noticed the battery was draining faster and clearing the cache did nothing so I bit the bullet and did a factory reset. That has not fixed the battery problem.
My Bluetooth seems to be the main culprit as it drains the battery constantly even when not connected to a Bluetooth device. I use it to connect to my vehicle so I do not want to have to turn it off and on manually.
This was never a problem on my S3 running 4.0 to 4.2 or my Note 4 from 4.4 to 5.0.1. Bluetooth never drained the battery on those OS's and I do not want to be told to manually turn it off when I don't need it. I'm hoping someone has or had a similar issue and knows how to fix it.
This is a stock unrooted Canadian Note 4
Thanks.
Anyhoo, after some arduous googling, I found that the Gasbuddy app has been giving some people the same bluetooth wakelock issues I've been having. I uninstalled Gasbuddy a couple of hours ago and the problem is gone.

Has anyone had issues with really bad battery drain on newest update?

I haven't noticed a drop in battery life after upgrading from CM10.2 to stock 4.4.2.
I have very few apps on my phone and I keep wifi and data off when I'm not using my phone.

It was my GPS eating up my battery. Mixed with the weather channel app. My battery was dead in 7 hrs.

Bad Battery Life
Hi
Yes, I have noticed a dramatic drop in battery life. I use to get home from work about 6pm with about 50% battery life. Now by 2pm I'm less than 10%.
No Bluetooth. No GPS. No NFC (this was originally on when getting to 6pm). WiFi on. WiFi Off. Doesn't matter. Turned location services to battery save or off. No new apps.
I have converted runtime to ART (worth having a read up on this), which can potentially give up to 20-30% better battery.
The funny thing is at home with full WiFi and strong 3G reception the battery life is exceptional! 2-3 days standby (light/medium use). The 3G reception at work.
A friend suggested that possibly the radio (3G) isn't locking on to a specific tower and keeps bouncing between towers chewing up the battery.
I will try a factory reset and see if it fixes the problem. From what I've been able to discover online it doesn't seem to be a very common problem.
Same Here
My girlfriend is having the same problem with battery drain.
GPS is off and she's using Wi-Fi at home.
When Google rolled Kit Kat OTAs I had to wipe her phone and flash the official Mako factory images to actually get it updated. So the phone isn't rooted and It's completely stock now. The 4.4.2 OTA update installed just fine. Then she noticed the poor battery life. Android system and Android OS are the 2 highest battery users in the list (will try to get a screenshot of this later)
Is the factory reset working for any one?
Has a reinstall of the factory images fixed this?
Any other suggestions?
Just wanted to ask everyone before I spent a bunch of time on it.
Thanks so much!
factory reset doesn't resolve
I did a factory reset and the issue still exists. I have removed 1/3 of my apps, 80% of the photos on my phone. I tried running Bluetooth off 100% of the time. Turned off location reporting. Turned off syncing any Google service I wan't using. None of these helped. My problem is intermittent. I will make a change then go a couple of days thinking "problem solved," then on the third day massive battery drain reoccurs. I think the battery monitor in the OS is unreliable when this occurs becasue it will report an app like "Flixter" as the main source of the drain. The next time it will be mediaserver, or TV Guide.

You got a lot of apps it sounds like. My problem has been eliminated sense removing weather channel app. Been good for two weeks

Same problem.
I have read millions of forums and this problem is not going away. I also have intermittent battery drain - it works for a few days and then everything goes back to sh-it. I've tried everything - deleting apps, turning off all services i don't use, power saving mode, sync, GPS, and nothing works.

Thanks for that note! I know my gf uses the weather channel app. Will tell her to remove it.
On a similar note. Now a few months later now and her battery wont hold a charge for more than 2 hours and wont charge to 100% every time. Her phone is only a year old. luckily she called google 2 days before the 1 year warranty was up. They sent instructions on safe mode and some other tips. Hopefully she'll end up with a new battery and i'll make sure shes not using weather channel haha.
Hi Guys,
I upgraded my Exynos Note 3 to Kitkat about 1 month ago, and everything was fine till about 3 days ago when I started experiencing some really bad battery drain. For the last three nights, my phone does not go into deep sleep mode at all. I first noticed this because I usually switch off data and wifi at night. Normally, I'd loose 3% battery overnight, which is good. About two nights ago, I woke up in the morning and I had lost 40% battery (90% down to 50%) overnight! When I checked out the battery stats, "gpsd" had used 80% of the battery.
Since we no longer have batterystats access in Kitkat, I installed the desktop version of WakeLock Detector, enabled USB debugging mode and connected my phone. Phone had basically been awake 97% of the time. Under kernel wakelocks, "l2_hsic" was shown as being the culprit. Now I have searched through various forums online (including xda) to try and find a solution to this. Suggestions vary from home screen replacements (nova launcher) to mobile tracking software (cerberus/findmymobile etc) to generally anything that uses location services. Some even suggest clearing application caches, disabling location services etc. I have tried every suggestion with no change. I uninstalled all mobile tracking apps, turned off location reporting, location history, and eventually location services. I've removed all battery stats apps. I uninstalled all my apps and re-installed them one by one, all with no change. Finally, I backed up my phone and did a factory reset. That seemed to work at first, but after about 3 minutes, "gpsd" was back again, and my phone would not go into deep sleep.
I've done 3 factory resets, and with no google account or samsung account configured, I still get "gpsd" rearing it's ugly head, preventing the phone from going to deep sleep and draining my battery. I'm at wits end.
Anyone know how to fix this? Would appreciate any help!
Anyone!?
OK, so I decided to take out my SIM card, just to see it'd make a difference, and what do you know! "gpsd" no longer takes up CPU time! So this is somehow related to my SIM card? Funny though, coz I'd even tried putting the phone in Airplane mode, but "gpsd" was still taking up CPU time. Does that give anyone an idea as to how this can be fixed?
bump
I'm having exact same issue with my exynos Galaxy S5, shame Samsung.
For the record, my issue fixed itself. Didn't do anything at all. It just went away and never recurred. I'm on the Russian lollipop ROM now, loving it!
Almost a year after the issue fixed "itself"... I have the same problem with my SM-N900 running offical lollipop, Im afraid I cannot wait a year to let the issue fixes itself... and cannot find a solution either.
Anyone that have managed to solve this?
THANKS IN ADVANCE!!
Huge battery drain when tablet is "sleeping" - probably because "bluesleep"
Hello,
I have problem on my N7 with large battery drain.
I had this issue witch Stock ROM, now I tried to root stock ROM (4.4.4) and install Greenify, but battery still dies after 2 days of no usage.
I tried to charge it fully, reboot it, cleared cache and dalvik cache, and put it to "sleep". After one night, 40% of battery was gone.
It seems that my N7 is not going to "deep sleep" for some reason.
So I tried to install numerous of apps to find what app is responsible for this. None was successfull, until I tried BBS.
In attachment, you can find BBS dumpfile. But it seems, there is some "bluesleep" kernel wakelock, which is responsible for all my troubles. Unfortunatelly, I dont know what this process is. Or am I reading dumpfile wrong and some other app/process is responsible for this huge battery drain?
I also attached screenshot from standard android battery statictics, which shows, that "Android OS" is preventing tablet from sleep.
Is there some way to fix this issue? Tablet worked normally for 1.5 year, but in last months is unusable, because it has dead battery everytime I want to use it.
Thanks for advices.
I would imagine bluesleep wakelock is related to bluetooth. Do you have BT on and/or connected to anything using BT?
If so try turning it off and see if it persists.
Yes, I use Bluetooth for my Jawbone UP24 sync. But I have this band only for a week. Extreme battery drain already was there before I have got UP24. In these times I had bluetooth turned off all time. So I dont think this is main reason.
I turned off BT. Lets see what happens in the morning.
UPDATE: You were right. It is bluetooth. When I turn it off, tablet is most time in deep sleep.
So probably rooting and installing greenify worked, but in meantime, I started using UP24 and Bluetooth on tablet.
I will try if situation is better with some AOSP based ROM. I did not wanted to flash another rom (than Stock), but I guess, there is no other way. Even clean Android on Nexus device is not usable with comfort...
Is there anybody else with this problem.It started monday i turned my phone on but it didn't start.The battery was 0% while i shutted it down with 78% of juice left.I charged the battery but it drains down real fast!Even with the screen off at night and no wifi or edge/3g/4g i still lose about 10% every hour!
I've used the note for two weeks without any problem.Rooted with Xposed Greenify and most of the bloatware disabled.Same setup as my Notepro 12.2 and galaxy mega(no problems with those devices).Battery life was pretty good about 5 a 6 hours of screen on time.
Tried better battery stats but no particular wakelocks or anything??I've ordered a new battery and that will arrive tomorrow.I can do a test then if it is the battery or the phone which is causing this problem.
It's a note 4 910c.
I have similar problem with my 910C...Everything was ok for first two weeks and problems started when I enabled LTE at my mobile operator. No matter what I do, I have huge battery drain like you said. I've also tried with disabling 4G/wifi/data/sync/airplane mode/removing apps... I even tried factory resetting 2-3 times and flashing stock rom via odin...Nothing helps...
I'm looking around on various note4 forums but I'm getting out of ideas...
I had an initial battery drain issue which ive managed to resolve. Took a few factory resets but for me it looked like the galaxy apps ap. Once you open it a single time it updates a few things and thats when i started to see wakelocks. Ive reset and avoided the galaxy apps completely and now wakelocks have gone. Might be a placebo but seems to work for me.
I have 2g,3g and lte enabled.
Oke i enabled 4g from the first time i used it so i don't think that is the problem.I was thinking about a factory reset but i'll wait with that untill i tested the new battery.
Will give a update tomorrow!
I had the same problem after one week of normal use. It was a hardware issue and the service center changed the phone board under warranty.
Well tried a brand new battery but still the same!Lose at least 10% every hour and i am not even touching the phone!!Sending it back for another one.
It's happened to me once but touch wood only once where I lost 70% overnight in airplane mode
Could be the media scanner? I was having media server and scanner drains until I installed a custom rom and disabled it.
I love my G2 which up until a few weeks ago has had incredible battery life. The phone is a D801 (tmobile) which has been running stock Lollipop (5.0.2) since I bought it. It appears that my Bluetooth has been taking up most of my battery. I don't recall it ever doing that prior to the recent battery drain. I have cleared out the Bluetooth cache and data, but it hasn't seemed to helped. I couldn't find any indication of a system update during this time. Any ideas, besides turning the bluetooth off when I don't need it?
