Bluetooth preventing deep sleep (Marshmallow) - X Style (Pure) Q&A, Help & Troubleshooting

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

Battery Life Since 4.4.2

I only had mine a week or so before the upgrade, but I would say it's definitely taken a hit. Now, screen is not always the biggest power consumer like it used to be. Android OS and Android System are taking a much bigger portion of the power than they used to. I always reboot the phone if something other than screen is monopolizing the battery.
Also, I heard there's a Qualcomm-specific bug related to powering the cameras, and that it's been a particular issue with the latest Skype builds.
I worry that they'll fix these issues quickly in the Android project but it'll take months for me to see the fix from Verizon, by which point my battery will have been subjected a lot of unnecessary heat and wear.
Tonnes of android os talk in this thread. Or try Googling it.
Basically, the more services you have on and apps syncing, the higher it gets. For experimentation .....disable sync, location, Google now and Amy other service you can find, and usually android os goes way down. Decide what's important to you and enable things again....but do like one change a day. And when your android os skyrockets again....you'll know the last thing you enabled is the main culprit.
Anyway.....a pile of battery tips in here, and android os talk. Take some time and read through some. Maybe start at last page and go back as far as you can.

Yes that battery life thread is very good. No change noticed here after the upgrade from 4.4
Sent from my XT1060 using Tapatalk
Thanks, but I didn't really have to add anything except 4.4.2. The increased battery draw was pretty obvious after I applied the OTA. Since the upgrade, this phone doesn't have anywhere near the life that it once had. And even after the bugs that are draining it are addressed how long will it take to get the fix through Verizon?

Trust me, you can fix it now....if you try. Just gotta troubleshoot.
Many have no such bugs....or they've disabled whatever has wrecked their battery.
Just gotta put in some time and your issues can be fixed.

Rooted with 4.4.2 and xposed/gravity box... Excellent battery life. Always 24+ hours use and 6+ hours of screen time. Granted I don't game but I always get some GPS and lots of music and browsing. I love this phone. I'm selling my n5 now.

I seem to be one of the few that's matching my Moto x's battery life on my N5.
Not sure why some have such bad battery life on either phone sometimes, I can only assume its app related and very hard to pin down.

I have noticed no appreciable change in battery life on any of the builds that the phone has had since I got it in December. Some days it is excellent, the next day, the wind blows the other direction (literally and figuratively) and the battery life is terrible with no change in usage or where my phone spends most of its time.
I had the Android OS bug after the OTA. I reflashed the stock firmware in fastboot and now it's gone back down to a more manageable level.

I actually had slightly better battery life on my Nexus5. I still haven't passed 7+ hours screen time on the MotoX. I did it multiple times with the Nexus5. Although I think the Nexus5 has some tech to save battery while reading or screen is still. It still wasn't enough to make me choose it over the awesomeness that is the MotoX. Although I do miss that raw power every so often.
I too have had the random drain issue. It's definitely app related and since I reset and have stopped installing outdated apps I've been fine.

You know, I thought it was just me, but the battery life definitely why down after 4.4.2! Yes they added a couple of features, but not that many for the drop in battery life experienced

My battery life is better on 4.4.2
The issues are with apps that have not been updated since kit kat. I've since removed such apps and have been enjoying much better battery life.

Installed ds battery saver. And let discharge overnight. Gsam reported a 2%/hr discharge. I had some apps not be shutoff
Install a xposed module appopsx or find a app on the play store if you don't have xposed. 4.4.2 requires root.
It's the built in permissions management. You can disable location for what app for example. It shows you what app is using that permission and how long ago it used it.

I unlocked and finally upgraded to 4.4.2 on Tuesday the 18th. I had a four day weekend and was on my phone A LOT (because I wasn't at work), so I wouldn't consider it normal usage to compare with. I'm waiting patiently for my averages to level off now that I'm back at work and on normal patterns again.
Before I wiped I took a screenshot of my averages according to GSAM, and it was showing 15h7m (7h42m active) average battery life, with 5h3m (7h12m max) screen on time.
I am currently a little below that, 12h20m (7h33m active) average battery life, with 5h28m (5h17m max) SoT. I was on my phone basically all day Friday-Sunday and had it on and off the charger. I haven't really had a full cycle of waking up, using the phone all day, and going to bed yet.
The apps I am running now are almost all identical. I actually removed 2-3 of them after finding that Gravity Box could emulate the features of standalone apps that I was using.
I am not using Greenify (I didn't see any substantial gain from it), but I do have the Snapdragon Battery Guru.
Overall, I don't think it's worse.
This was my drain while I slept last night. That's even better than I thought it was. 4.4.2 BTW. I'm pretty sure I don't have any apps installed that haven't been updated since Kit Kat came out.
Having updated applications makes a huge difference.

Some have got down to 0.5 per hour drain on standby, but I never could. Our x is about 1 also. Its strange, cause its set up about the same as my n5 and it can get to 0.4 usually, not in airplane mode either.

The 5 is a beast on standby drain. I miss that. I'm not even going to try for less on the X. I just attribute it to the Touchless and Active Controls. Whether that's the case or not, who knows.

An extremely light user may get more mileage with lower standby for sure, but doesn't really affect my wife. She charges over night regardless.

I have always wondered if touchless and active notifications were the ones to be blamed for the average 1%/h drain on standby but never did a test to try it out, until today
I charged my phone to 100%, turned off touchless controls and active notifications and let it rest through the night, when I woke up 5h and a half later (yes, I usually don't get much time of sleep), I was still on 100%, just I did when I had my N4
I guess these stuff take so much battery because they have to keep the phone "awake" all the time to recognize your voice and to know if your phone is upside down or in your pocket or whatever and as much as motorola made them separate CPUs to handle it with less battery consuptiom, they still take that 1%/h... Probably we would get a higher %/h if it wasn't for the 8 chip processor motorola came up with
Actually I even think that it has something/all to do with the high android OS usage that we get, and to be honest, I really don't mind getting 1%/h drain on standby overnight if I can wake up any time in the morning and ask to my phone to do almost anything I want or check my notifications without having to light up the whole screen, so I'm quite pleased with it

Note 4 and Android Wear device - battery drain, experience?

So I've recently bought a Android Wear device - LG G Watch R.
Quite expectedly I've encountered a problem which seems to bother me a lot - battery drain.
In order for Android Wear device to work properly it needs Google App to be enabled on the phone. Unfortunately it needs Google Now as well ;/
I've disable everything which can be disabled or stopped - location, history, some-automatic-bs. Judging by PC Wakelock Detector the most usage is for com.android.google.gsf and com.android.google.quicksearchbox
Now I see a lot faster battery drain and a lot of wakes in the battery usage.
Someone else using Android Wear to share some knowledge?
I also have LG G Watch R.
Battery drain is noticeable but it is expected. Watch and phone are permanently connected by bluetooth and some services running.
But, battery stay one day without any problems and I always charge the phone every night so thats don't bother me at all.

Hi
I have also noticed this as well, mine seems to have the Android OS as a source of wakelocks, not sure what though. Sometimes I have the Android OS with around 2hr+ of awake time.
Is it the same with all smart watches? I was thinking of getting one of the Samsung ones but not sure which one yet.
I think it's to do with bluetooth being on all the time rather than the type of watch.
I have a first generation Samsung Gear (a.k.a. Galaxy Gear) now with Tizen OS and theres no notice of any significant difference in battery use.
I like LG and Motorolla watches but they work with Google Now and in Portugal there is no use to the app and i remember on my Xperia S Google Now drain my battery in few hours! Since my Note 3 and now Note 4 i allways have that App desable.

Battery Drain

I just got my phone a couple of days ago, and seem to have some insane battery drain. I leave it on overnight and in the morning it seems to be down to about 10%.
Is anyone else seeing this sort of issue?
Here are some screenshots:
While the battery is OK but not stellar, I notice you have Wi-Fi on? Turning that off overnight helps immensely.

I have a Galaxy S4 running 6.0.1 from JDCTeam that gives me way better battery life with WiFi turned on all night, and runs way more apps than this phone (plus, the battery is just 1850mah). I suspect that there might be a lot more going on under the covers here with respect to hidden services. I am not happy with the fact that the battery usage stats are hidden.
Should I root and try to use betterbatterystats to figure out the real problem? or maybe just assume its defective and ask for a replacement?
I think you need to turn this off too. Otherwise, it will keep searching for wifi even you turn the wifi off.
I'm having no battery drain issues. I have the Grey one.
I have turned off mipop and voice print. Dunno if that could be the culprit.
Turning off Smart Power Save increased my battery life
I have the same issue... 10 to 15 % drain over night other than that the phone it's amazing... When I got the phone before I even turn it on I got in recovery an did like 3 times a factory reset ... I'm gonna keep the phone for 2 more weeks if the drain continue I'm sending it back to newegg ?

No bad drain here, I only dropped 2% overnight (11pm -7am)....Wifi was on and I received several emails and a few text that were waiting when I woke up.
yeah the battery was massively overrated pre-purchase
Thanks dougm0 and Barsky ... I turned off Smart Power Save, MiPop and Voice Print. I also made sure that the location section was only using GPS (not wifi+bluetooth), and it all made a difference. I still feel like I can squeeze out a lot more performance here. My deep sleep numbers in better battery stats has improved, but it's still not where I want it to be. As I make more tweaks and get better battery life, I will post screenshots and settings tomorrow (maybe it might help someone else).

Something I always notice that you might also want to take into account. When you get a new phone you are not using it as you will regularly be using it after the new period wears off. You are probably testing all the different aspect of the phone and just plain messing around in ways you do more of when the device is new. I always get horrible battery time in a new phone
No issue with battery drain - left my phone at 100% overnight with WIFI ON, in morning it was at 97%. I think I will take it as 3% drain over 8 hours.
You most likely have an app that's causing wake lock issues. It's a common problem on any phone.

My battery is amazing on this device.
I Don't mean to rub it in anyone's face that have these issues. Must be an app that's causing it.
Coming from Note 4 and Moto X Pure. This is twice better. I don't read screen on time on this device because it doesn't show it. I don't even need those stats. After 16 hours of the charger with same use I get home with 40%+.
My Note and X Pure were dead by then or have been connected to a charger by that time.
Hope y'all figure it out.
Battery life on my phone is not that great either. It's not horrible but I expected better. I think it drains 3% in 4 hours with wifi and sync on. I did turn off all the scanning and battery saving feature.
I recently noticed the battery on my phone was just 3140 mAh instead of 3250 mAh like on the website says it should for the US model. Can you please confirm what capacity your battery has?

It's 3250 for the US model, but there is an issue with the partition where it still shows the original 3140 mAh instead. It has been notified to ZTE and they said that it will be fixed in the next update.

How To Get Best Battery Life?

Sooo, I just got the Fossil Q Explorist HR. And so far, I LOVE it. It looks so good. It's better looking than my Gear S3, way lighter, and a lot thinner too.
BUT, so far, battery life isn't looking good. I got it today, so I definitely need a couple days to be sure, but I've had it off of the charger for less than 3 hours and it's at 64%. I did all of the setup while it was charging. All I've done off the charger is update some apps, change the complications, and setup Fit.
What I've done to hopefully help with battery life (again, while charging), is turn off everything except Bluetooth and location, I've disabled any apps I don't feel I need or hopefully won't cause problems disabling, I've turned off permissions for a couple as well. I have always-on on, auto brightness, Fit with heart rate on, and that's pretty much it. I really need to get a full day out of a smartwatch, INCLUDING using it for up to an hour workout with Fit. The Gear S3 would do that as well as last about 24+ hours.
Am I missing something? Should I NOT disable apps or turn off any permissions? Is there a better way to set this up to get some decent battery life out of it? I really really want to get rid of my Gear S3, and I'm hoping this one will help me do that. Let me know what you have done to improve your batter, and how many hours your watch lasts.
Please and thanks!
Man, Fit workout really takes some battery! I used strength training, which detects workouts, has a built-in timer, etc. It used 24% in one hour... I'm going to use the weight lifting one tomorrow to see if it's any better, it doesn't do any of that, just heart rate and calories burned. Before my workout, 4 hours in I was down to 76%. 6% per hour. Not horrible, but could be a LOT better.
Seriously, anyone have any tips to help with the battery life? Disabling any particular apps, permissions, anything? Should I NOT disable anything? I really want to keep this watch, but as it stands, without using it to workout, I *might* get through the day. I refuse to have to charge this thing at some point in the day just to make it until I take it off.
I use mine for notifications, music control, maps, alarms and today even translating. I went to work at 5:30AM and came back at 6-7PM and had 53% left. I also called an Uber and tried Shazam and some other stuff with it. I use fitness only for my daily walking.
I can't complain.

What watch do you have? And how did you set it up? That would be great. Mine's on the charger now. It was at 13% just a few minutes ago. Came off the charger at about 7:15am.
I have the Q Explorist HR (Silver with leather). I have display always on, turned on. I was Wi-Fi usually turned off but I had it turned on for some time too (I wish they would add Wi-Fi into the quick settings). Brightness was set on automatic. Gestures was all turned off, touch to wake was on. Location (GPS) was on. NFC was turned off (I never use it).
Also very important is the watch face you use. The more colors you have, the more information witch updates often you have on it, the faster it drains battery. So I use the simple black watch face, with battery, weather, date and alarm widget.
The 2nd battery killer is the connection (Bluetooth, Wi-Fi, GPS). Try to stay with 1.
Gesture controls often activate when you even don't need it because you run or shake hands. So I turned them off. Only touch to wake I leave turned on. The watch wakes up on notifications anyway and time is shown as well. If I need weather, I touch the screen.
I have the "OK google" detection turned off. Never using it.
I hope this helps you squeeze some more juice out of the watch, I was very surprised yesterday how long the Battery survived. But as mentioned, I use it for basic stuff.
Take care and let me know if it helped.

Yeah, you can disable quite a few actually. And turn certain permissions off on some. The problem is, some apps talk to others, and you can actually cause more battery use if one is disabled, or something turned off. I'm so new to wear os, I have no idea if I'm causing that or not. I'm going to see what today brings, but otherwise I'm going to reset the watch tonight and leave apps alone.
Thanks again. I'll report back for sure.
I will look into that, thanks. I am using my watch today since 5AM and now it's 3PM here. I have 69% left.

I haven't tried. Is there any benefit to it?
So, I turned off wrist wake up, and that was the trick! I took my watch off at around 9pm last night (off the charger at 7am), and even after an hour workout and run, I still had close to 40% left. And I actually don't mind just seeing the always on face most of the time. It's a little less annoying the constant waking up and such. Thanks, that really helped. Def keeping the watch now
Glad it helped you. But crazy how one setting can make such a difference.

Seriously! I would have never guessed that it waking up when tilted used that much battery. It's seriously at least twice as much battery life now.
I know right, I am testing it atm which Wi-Fi, GPS, NFC and heart rate stuff on all time and even then the battery life is more then 1 Day.
This one function is a major energy killer. Hopefully the Wear OS 3 update fixes this.

I've had GPS and heart tracker on this whole time. Those are essential to me. The only thing I dislike about not having the tilt to wake on is, the always-on does not really work with adaptive brightness it seems. If it's darker when the screen is fully on, it stays that way even with I go outside for example. It also takes a few touches sometimes to wake up. Are you having either of these problems?
Anyway, agreed on the new Wear OS. I really hope it fixes some battery issues.
Yes, I experience the same issues. The Auto Brightness works fine for me but the extra taps to wake up are true.
They said roll-out is until end of October so let's hope it's starting soon.

Tab S5e horrible standby battery drain

Last week I have purchased a brand new S5e, and overall I am pretty happy with it, outside of one big problem: the damned thing loses like 30-40% of full battery charge per day while sitting in my desk drawer, doing absolutely nothing. This is, frankly, unacceptable. My two-year old Galaxy Tab A loses 2% per day when idle, so I would kinda expect similar idle drain from the new device as well, given they have similar-sized battery (7040 mAh in S5e vs 7300 in Tab A).
I have tried:
Uninstalling unused bloatware via ADB pm uninstall
Turning off data and wifi
Turning location off
Restarting the thing
"Sleeping" of all the apps via Samsung's battery save features
Factory resetting the tablet and repeating the above with no extra apps installed
Tried the "Extreme battery saving" feature, but frankly, that leaves the tablet in absolutely unusable state because it limits you to like 5 built-in apps and portrait mode. Who the f uses their 10" tablet in portrait mode?!
Currently trying Airplane mode, will see how that goes, but I'm not keeping my hopes up at this point. -- Update: Airplane mode seems to have satiated its hunger for battery, but that's not really an option to keep on at all times. Any other ideas?
I'm frankly running out of options here. I bought this for xmas and it's, tbh, unusable in this state. It does have the latest software update from Samsung (October 1st, 2019).
I've tried running BBS to shed more light on what's going on, and while it's showing the device is spending nearly 50% of the idle time in "Awake (screen off)" state (compared to 2-4% on my tablet and phone), but neither Kernel nor Partial wakelocks show anything egregious. And normal battery stats are about as useless as you'd expect, too.
Currently considering taking it back and asking for a return or RMA, but figured I'd ask here first, maybe one of y'all has encountered the issue and by chance knows what's the problem and how to fix it.
You need to take an idle log with BBS and post in the BBS thread asking for some analysis.

You need to take an idle log with BBS and post in the BBS thread asking for some analysis.

Remind me, how do I do that?
Naptime by Francisco Franco will turn off Wifi / Data / GPS when the screen is off, and turn it back on when the screen is turn back on. Works best on Rooted devices though.
I'm using Lineage 16 on my Tab S5e, I generally get somewhere between 7-8 hours of SOT, and go 5-7 days between charges. I use Naptime on all my tablets have for a long time. Found it doesn't work as well on cell phones. I haven't paid attention to what my idle drain is, but overall my battery performance has been excellent with Lineage.

I have figured it out.
Turns out, the tablet has some issues with the provider's sim card and plan. I got internet-only plan and it does not allow for neither outgoing nor incoming phone calls. And my other tablet has a normal calls+data plan. When I swapped cards between the two tablets the drain issues also swapped! Except the older one wasn't draining nearly as fast, but still noticeably enough. While new one only lost 1% overnight.
So looks like I will be staying with my old plan, maybe upgrade it a bit. Oh well, no big loss, but mystery solved.
