Hi Folks,
I have been suffering with abysmal battery life for the past couple of weeks since I got my device(910F). So much so that yesterday I rooted the phone just to get betterbatterystats to give me more information on what was draining the battery.
Low and behold it turns out bluetooth is the culprit. I have a moto 360 that I have paired with the phone.
Before I switched bluetooth off i had 2 kernel wakelocks occupying 88% of the time since i took it off charge (bluesleep & msm-serial_hs_dma).
As soon as I switched off bluetooth these wakelocks where immediately released.
Also when checking CPU states prior to disabling bluetooth no time was spent in deepsleep. As soon as I turn off bluetooth I'm now seeing 23% (and growing) of the time spent in deep sleep.
Has anyone else had this issue with their Note? Seems like bluetooth is keeping the phone awake and not letting it enter deep sleep.
some images to help see what im on about!

I have exactly the same issue on my Sony Z3. Take a look to here. You'll feel at home!!
Did you find any solution workaround?
This things is driving me crazy.
It looks to not a very popular issue around XDA. Could it be an app? Hw problem?
My note 4 is on 5.0.1, and this just started yesterday. I always keep my Bluetooth on with great battery life. Today, however, my phone will not enter deep sleep until I turn off Bluetooth.
I cleared the data on the Bluetooth and BluetoothTest processes, and my problem is solved. Now, understand that I've been turning bluetooth off and on constantly as I use my hands-free device for calls and turn bluetooth back off to save battery, so something may started functioning properly along the way without clearing those previously mentioned data and caches. Either way, I leave bluetooth on 100% of the time again, and my battery life is again stellar.

I'm on stock 4.2.1 ROM and Franco r23.
I have my Wi-Fi policy set to "never", which should turn it off when the screen is off and the phone is sleeping.
But it's not doing that and I don't know why?
I use Better Battery Stats and an attaching a couple of screens so that someone can suggest why the Wi-Fi refuses to shut off and allow the phone to truly enter deep sleep. The second screen shot shows that Gmail is the top process in terms of battery usage, so I'm wondering if that's the culprit as gmail sync is always set on push, and can't be changed to any other schedule?
If so, this is a huge oversight by Google.

I have the same issue but worse.
Not only does my wifi not turn off no matter what the setting is, it does shut off my mobile connection.
When I turn on the phone after a long time period I see the mobile connection triangle blacked out and after a few seconds turns back on.
After that the issue continues even when the phone isn't in deep sleep. VERY ANNOYING
But no matter what the wifi is always alive.
Still not sure this isn;t a hardware problem and if it is I'm ruined because I don't live in the states.
Let me know if you find a solution, I'll do the same.
BTW I'm on 4.2.1 stock rom as well .
same here, wifi stays on, even if in deep sleep...

Other strange problem, when I manually disable WiFi, like 2 times in picture, data does not turn on. I have to switch 2G-3G and it connects or airplane.
This is not fair, finally after all those years waiting perfect andorid phone... like someone previously said Nexus 4 is like Bugatti, nice, fast and powerful but only for few miles.
My phone's battery is constantly being drained by one thing or another. I shut off location services, and Google Search becomes the problem. I shut off Google Search, and Play Services drains the battery. I uninstalled Play Services and now my battery use looks like this.

I don't know what to do. Is it time for a factory reset? I am rooted, but stock. I assume I would have to unroot before a reset.
Give us some specific numbers and we might be able to help. The screenshot you put up means nothing. Either more info or BBS screenshots (or maybe even Wakelock Detector)
Yeah, hop on Android Market. Download Wakelock Detector and the next time you pull it off of the charger leave it be for a couple hours. It'll keep track of what is keeping your phone from sleeping. For example your phone can be awake without the screen being on, and that's probably where the issue lies. Make sure it's set to CPU Wakelock. Then come back with some screens of that. We'll get a better idea of what we me be able to do to help.

I've been using Wakelock Detector, but I guess I am unable to interpret the results. They seem inconsistent. My phone was recently rebooted and is being charged, but I will post a shot of WD later. The top result earlier today was Google Music (which I almost never use). It did not seem like a terribly long period of time it was on, though. I think it was less than 6 minutes. I turned off sync for it regardless.
I assume BBS BetterBatteryStats. I'll go purchase it.
Thanks for the help. I do appreciate it.
Hm... How long have you had the phone? If you're in the grace period still, it couldn't hurt to replace it. Every now and then, defectives slip through. Knowing how well the G2 battery is supposed be, I do it very unusual that you're suffering a hit in that department.
Edit: I still think there has to be a rogue app somewhere. Especially with android system taking so much of your battery.

Battery is almost full, doesn't seem odd to me with phone sleep. Need wakelock info form BBS.
I'm getting this bug in every Lollipop Phone I own. And sadly this bug seems to be present in the M Developer preview too.
Usually my day starts with wifi but as soon as I leave the wifi connection and start using 3G the battery starts to drain.
It has gotten so annoying that I switched back to KitKat and my phones are awesome again.
Present for me on Z3 and S4

I noticed this today. Was using WiFi screen was at about 36% use and Android OS at about 6%. Switched to Mobile data, And before 30 minutes, screen was at 28% and Android OS was 30%+
Crazy really! Don't know if a reboot would fix. Back on WiFi tho and it seems normal again.
The above comment was made by me, my friend logged into his xda on my phone and i didn't know, when i knew it was too late.
Basically every app that uses mobile radio keeps the connection active and drains the battery fast.
As seen in the battery tab with "mobile radio active" for hours.
At first I switched to lollipop I thought its just an "feature" but its the bad bug.
Especially for people who doesn't charge their phone for days because of light usage

I take it you are on CM now?
The Z3 is now .77 stock KitKat, the s4 is CM11 M11
Thats what it should look like:

so, overall, the power consumption in KK is way better than in L? [assuming similar usage]
cause i bought this phone already on L...
On WiFi it's as good as Kitkat, the problem starts when you have mobile data enabled, from what I hear the issue carried on into the test builds of Android M.
Phonearena even did an article on the issue, and it has the 3rd or 4th most votes on Google 's bug tracker yet it's still labeled as small priority... I hope Sony fixes it by itself somehow.
Since I updated my device to Nougat 7.1 stock rom my phone switch off at 30-40% battery randomly.
I want to ask if replacing battery would solve this problem? Is there any other work around for this specific problem?

Same happened with me 2 days ago. Phone switch off randomly at any percentage below 50%
Sent from my XT1562 using Tapatalk
Same here, the device goes suddenly from 15-20% to 0 and then it shuts off. Could seem like an old battery symptom, but since it happens only on Nougat, it is likely to be software-related.
Can i say that have the same problem if my phone shut down on 7%?? :/ i dont understand why it happen
I have the same problem. To prevent this, I turn on battery power economy when it reaches 40%.
I've had a similar problem, changing the battery has solved it for me

It happened to me in all custom roms, after changing the battery it works fine
Sold my moto x play & bought MI Max 2. Goodbye guys
Hi there, having this exact same issue... any workaround or solution?
thanks in advance
I tried several roms, formatted, flashed stock, etc., didn't solve. Changing battery (it was 2 years old), the only and right solution for the problem.
Actually this happens when the battery gets weak. I have been experiencing the same problem for nearly two months. At first my X PLAY tended to switch off when charge was around 22 percentage and then battery got way too weak. After getting too weak,my X PLAY would switch off randomly at 30 to 40 battery percentage. Actually i have experienced this not only in X PLAY, but also in wide variety of Androids like XPERIA ZR , XPERIA Z2 , MOTO G2 , MOTO G4. So the solution for all these mobiles was to go for a new battery and it was brand as new with a healthy battery life.
Get back to MM problem will get solved. Done the same with my friends moto
Hey everybody!
I have noticed some strange behavior with my TicWatch Pro 3 Ultra GPS.
During the day, the power consumption is moderate and absolutely acceptable. However, the power consumption is significantly increased at night.
Looking for the cause, I found out with the help of Battery Historian that the GPS is obviously the reason.
When I go to sleep, I always turn on Airplane Mode on the watch to further limit all network activity and save power, and turn it off accordingly after I get up.
I have attached a screenshot from Battery Historian. I have inserted the vertical red bars as markers, when the Airplane Mode was activated or deactivated by me.
The process that activates the GPS seems to be Wear OS itself (com.google.android.wearable.app).
I had also already reset the watch to factory settings.
The first night, interestingly, GPS is only ever activated briefly. Whereas on the second night GPS is almost constantly active.
Before the factory reset, the GPS behavior looked similar.
So far, I had always left GPS activated on the watch, since I assumed that it would also be deactivated when Airplane Mode was activated. However, a look into the settings told me that this is not the case.
Ultimately, I do not understand why the watch wants to access the GPS constantly and almost permanently when Airplane Mode is active.

I've exactly the same problem. I was getting crazy as the watch consumed 3 time more battery overnight with airplane mode than during the day.
Maybe the problem is related to not having a connection to the phone. As far as I know, when the watch is connected to the phone, it doesn't use its own GPS. I assume there must be some internal process (like updating the weather) that tries to get GPS signal.
I'll try different setting combination on the next nights
Dear friends,
I came here for the same exact issue and I'm glad it is a known bug and it was detected.
I'm asking to the OP which is the app you use to have that battery stats. I need it also
Thanks in advance

Same issues here, can anyone post the link to ticwatch FB on this issue?
I don't think the affected WearOS version is something we can really opt-out ...
