Lost 50% Battery Overnight - Nexus 5X Q&A, Help & Troubleshooting

I've had the phone for near a week now and this is the first time doze has failed me. Left it alone at 10pm with about 50% left and looks like it went to zero in about four hours. (screenshot) I've tested other nights and it worked as expected -- wifi and cell coming on and off periodically. When checking usage, I was disturbed to find Facebook took up 25% of my battery. Is there some way Facebook is overriding doze?

Wow. Looks like it was constantly awake during that time. You didn't happen to turn on photo syncing with Facebook?

Facebook is one of the worst when it comes to battery drains, I stopped using it and i just use a browser to stay logged in. Snapchat is also pretty bad, I think it was top 3 in my list while I slept earlier. First time happening, i turned off location on snapchat, ill see if that helps

Same here. Facebook did this to me back when I had an HTC Hero, killed my battery in 8 hours no problem. The moment they changed the application to a "service" and had those wake-lock bugs I ditched it, never looked back.
No application should install itself as an always-on service unless its there for push messages. I decided that having my phone last all day was more important than getting facebook messages immediately.

Yea, it looks like it was constantly connected. Don't have photo syncing, but good thought.

I stopped using Snapchat a while ago for that reason. Facebook, however, never really gave me a problem on my N6. It usually hovered around 6-7% use. No app is worth that much drain, let alone Facebook. If this is a normal occurrence, I'll probably just uninstall it.

Hopefully this was a one time occurrence since it worked fine on my N6. I've got no problem getting rid of it though, because like you said, I'd rather have my phone last all day (or night in this case).

Second Night Update
While I agree the Facebook app is bad, it looks like it was not the culprit. Uninstalled, doze again failed to kick in overnight and drained 18% over about seven hours. Not as bad as the 50% the first time, but still no bueno. It looks like Android OS kept it awake for seven hours. I know doze is pretty new, but there are some smart people here; anyone got any ideas/theories as to what's going on and remedy? Screenshots

Good to know I'm not alone! Even after uninstalling Facebook I've got the same problem with Android OS keeping it on. I'm considering clearing the cache and see if that changes anything.

Wow you have a perfectly diagonal line. Try a battery monitoring app. Might have more useful information as to what is draining overnight.

I did a factory reset and installed ~10 of my most used apps instead of restoring all apps and it's been sleeping fine now, no wakelocks
I also turned off WiFi and Bluetooth scanning, location services are on battery saving, and Google location reporting is off

I am willing to bet there are going to be some hiccups with marshmallow or even some newer hardware features of the phone and some apps until everything gets up to speed.

Just wondering, what build are you guys on? MDA89E or MDB08I?? I'm on MDA89E

I got 08I immediately after turning it on, Ive always lost like 1-2% overnight.
Maybe that is what the last-minute update was for, fixing that bug that you (unfortunately) found.

[Q] Battery starts draining at exactly 5am.

I started using JuicePlotter yesterday, and noticed that at night my battery barely drains, if at all (hooray for setcpu!). Until exactly 5am when it starts draining heavily at a steady rate. I've done all of the obvious stuff (I think), like making sure I have nothing set to begin syncing at that time, but I can't seem to pin it down.
Does anyone know of a way to find out what's turning on at 5am and draining the battery?
Do you have an Exchange sync setup?
If you do you may want to check and see if your Peak times start at 5AM. If so you may want to set it to update less frequently.
Does JuiceDefender run on a schedule and keep 3G off until 5am?
Thanks for the suggestions guys
I have exchange set up, but its set to "as items arrive" for both peak and non-peak hours (which is set to 8am anyway - yeah, being on call 24/7 sucks).
I'm also not using any kind of timing app like juice defender to schedule anything.
One wierd thing I noticed that may be tied to this, is that certain apps like twitdroyd and fb update immediately when I open the apps, even though they're set to refresh manually, and not to update when I open the apps. Still trying to figure that one out.
Night mode is enabled from 2 am to 5 am. Depending on your settings, Data/3G/Wifi are disabled between those times.

He is referring to JuiceDefender, I bet. I would guess a lot of people who use JuicePlotter also use JuiceDefender. It does exactly as he described: turns data off from 2am to 5am. I use it, and it does help. It also keeps data off when the screen is off during the rest of the day, except for a quick check every so often.

rats - I was hoping he was referring to something in regular settings. I'm not using JuiceDefender, or anything similar.
well if you do have it setup for everything to be off between 2 - 5 then wouldn't that make sense that as soon as 5 hit your apps will start syncing even Google apps as they have been trying to sync that whole time and just started queuing up and finally your radios turned back on. I have not used juice yet so i do not know much about it just throwing in some pennies.
One other thing the refresh manually is only for when the app is closed as soon as that app opens its going to sync with its servers. When you set it to manual then that means when you open the app you manually refreshed it and the phone did not do that while idle or you were busy on some other app. Its like twitter for desktops if you set your refresh manually then while the app is open it will not refresh until you hit refresh

One thought: Do you have a good signal in the spot where your phone sits at 5am? A bad signal is the best way to drain a battery fast. A friend's house has an awful Sprint signal, and my battery will drain in four or five hours there, even with no use, whereas I get well over 24 hours with average use in good signal strength areas.
Back when I first got my phone, I used System Panel to figure out what was causing the battery drain. I liked using it so much, I even ended up purchasing it. The history part is what you want, and it will work without paying for a bit, so you can find the problem.

that would make sense if I was running something like that, but I'm not - as a part of my job, I need to be able to reply immediately to specific emails. At any hour. Total PITA, but hell, it's better than not having a job, right? JuicePlotter's pretty neat though - it just sits in the background monitoring your battery levels and graphs them. For example, it was showing an almost horizontal line from when I stopped using the phone the night before until exactly 5am when it started a gradual decline.

Are you sure about this? I mean it makes sense, but I would be willing to swear that back when I was running stock I would open FB or Twitdroyd and it would wait for me to hit refresh before syncing with their servers. Twitdroyd, for example, I would set to keep 80 tweets, and I would check it only occasionally, so I could read those 80 tweets whenever I wanted. Now when I check it, because it syncs immediately, I lose anything older than the most recent 80 tweets. As a workaround, I've increased the number of tweets to keep, but it's still annoying.
ok so hmm what rom are you using. not wanting to bash the dev but could it be that rom?

My signal's not great, but the phone didn't move between 4am and 5am, and the battery only started draining at 5am.

I actually purchased SystemPanel this morning with the hope that it would help me get to the bottom of this (I had been using the free version for a while, and now I had an excuse to buy it). It shows me history of battery, device usage, and cpu activity, but even if I see that the cpu or the device is being used, I'm still not sure how that's going to help me pinpoint what's going on. First I need to build up some history anyway though.

Crazy battery usage after OTA 1.72.405.3 How to find out what is going wrong?

Hi all,
After instaling OTA 1.72.405.3 the android system is eating away my battery like crazy.
After 5 hours my battery was down to 29% (71% was used) and the android system was responsible for 60% of this. In my CurrentWidget log I can see that (with the phone in standby) it uses ~130 mA to ~160 mA.
Does anybody know what is going on or can anybody help me by telling how to find out what is going on?
[edit: If you have the same problem, please post a reply so we can find out if this is a big problem! Thx]
This happened to me yesterday! Found out that the system process had pegged out the CPU @ 100%
I couldn't fix it, and in the end restored to factory settings. Has been OK today but I killed the battery in about 4 hours.
Radio and kernel updated?
Sent from my Desire HD using XDA App
yes, i have the same problem! i posted another thread about it (titled constant sync after OTA update) as i first noticed the issue when the sync icon was always being displayed.
today my battery hit 20% after 6 hours with android system taking up 50% of the battery usage. its ridiculous!
if anyone has a workaround or a quick fix please post it up - this is untenable!
I have exactly the same issue, no problem with battery life before the latest OTA, and now the phone is dead within 8 hours with no usage, simply in the pocket with the display off.
Not happy at all, the phone is virtually unusable at the moment as any action accelerates the drain.
Strange! My phone is now with more battery life, after the update. It is SIM free ...

I posted this in another thread -
There seems to be a bug in the update for anyone who had HTCSense.com sync'ing turned on. Either disable all sync'ing for that and / or sign out of that account. It was consuming 100% of my CPU cycles and keeping the processor at the 1ghz mark. Once I disabled the HTCSense.com sync and rebooted the phone, all is good. I went from 100% CPU usage to about 4% and less when idle.
Personally, I'm not sure about HTCSense.com anyways. Way to buggy. I have all my SMS's backed up with SMSBackup+ to my Gmail and my contact / calendar is on Google. I've Wave Secure to lock down the phone if needs be / to find it. I think it's more reliable as well as I used to get a lot of "can't connect to the phone" on HTCSense.com and Wave secure uses at Text Message based system to activate the necessary features along with locking down the phone if the sim is removed / replaced! NICE!
Anywho, anyone who is having battery problems / finding the CPU is topepd at 100% try the above and see!!

I followed up with this:
I must say, I'm quite impressed with the battery life since the update (after I got rid of the 100% CPU bug).
I plugged the phone out at 11am this morning. Quite heavy texts (50+ sent today and at least that received). 10+ calls (incoming and out going) at 3-10mins each. Some Angry Birds, Some Market Updates. Disconnected my Facebook Acc and reconnected to cure a bug in the calendar (facebook entries were there twice), so all that data had to reload. Twitter usage through out the day. WiFi on all day. GPRS Radio only.
Now at 12.15am (so over 13 hours later), I've still got 50% Battery left! I would NEVER have gotten that previously. Not with the heavy use I gave it today.
How are other people finding it!?

Thanks for that. I dont really use any of the sense features myself so i've now disabled sense syncing completely and will see how it goes (once its fully charged again!). will keep this thread updated with any news from my end in any case.
I did notice the sync logo was up quite a bit... interesting!
Mine did it randomly... couldn't clear it so just went for factory reset which appears to have fixed it!
May turn of HTCSense however if it is likely to be causing problems...
I got the same Battery problem after new OTA and Im going crazy! What can I do? My battery lasts only about 4 hours now!!!!!!
Should I factory reset and wipe everything???
As ive posted in a few other threads i went into stock application manager and force closed everything i could to do with google, htc , friendstream, maps, facebook etc. After that my cpu 100% problem stopped, has never returned and battery life has improved compared to before the update.

I have disabled now HTCSense.com sincronization. I will see how this works tomorrow for me. I will let you know guys
I had htcsense.com enabled but to be frank I never really used it much...
disabled its syncing (every 3 hours I had set), rebooted, still had "android system" at ~65% and htc sense running at about 15% (tell me, I use launcher pro 99% of the time, is there any way to actually kill the sense ui? I swear its in the background)...
This did nothing, I tried actually removing the account, and even before a reboot the proc. usage dropped down to about 15%, which was apparently being used by the monitor I use (osmonitor). rebooted, let the phone settle, it did a sync, all seems well... So in my case an actual removal of the account was needed.
Try turning USB debugging on/off. I have it off after the last OTA and I have no /INIT problems. Maybe they fixed it...
I had the same problem, with the cpu running constantly at 100%. For me the solution was to remove the HTC Sense account, and then adding it again. After this the cpu usage dropped to normal.
well its been nearly 4 hours unplugged and i'm down to around 80% with around 30m of calls made and a dozen texts. not fantastic, but much better then before.
Did you try USB debugging? previously that has been mentioned as the CPU eater and battery hogger... just a thought..

Confirmed. I had the same exact problem and removing HTC Sense account did the trick.
I tried adding it again, but the cpu drain started again..... so I'll use it for some time without SenseSync.

Removing Bloatware aka "what can I do to get better battery life?"

So I think by now everyone has realized the battery life on our A100's is mediocre. I've actually been pretty content with the usage I get out of mine. What I'm not so thrilled about though is the idle usage. I'll leave for work in the morning with my A100 at / above 90% battery and come home after 6pm with it completely dead. I have wifi set to turn off when the screen does, any app I have that has a sync option is set to 6+ hours, and I've stopped using live wallpapers. Every other electronic device I have can usually last a full day when not in use(my old netbook gets 3 hours of use on battery but 2 days while sleeping).
I've started looking into the "bloat" / OEM apps installed by Acer. Nidus, sync, socialjogger etc... My main questions are; what can be removed, what can I live without or would be better of with a 3rd party app, and which Acer apps can possibly be causing the idle/sleep battery drain? This thing should still last a full day while sleeping, shouldn't it?
Any suggestions? Anyone else have this issue? Thanks!
You could try using Bloat Freezer to freeze apps. I have alot of the acer stuff frozen, and with it in standby, easily goes a day. Things like socialjogger, acer init, etc.
These are the apps I've completely removed from system apps, made a backup of course..
AcerClockwidget.apk&odex
Agendawidget.apk&odex
Aupeo.apk
Clearfi.apk
DTG.apk
LinkToFacebook.apk&odex
MusicA.apk&odex
MyLocationWidget.apk&odex
NemoPlayer.apk
Planner.apk
SocialJogger.apk
Solitaire.apk
Xt9.apk
You can also remove appinapp butyou will loose the games multimedia app I use that so kept it.
Battery life hasn't been that bad on mine. I expected worse, I just picked mine up last week and after reading reading reviews I expected worse.

WOW! I can use mine all off and on all day and don't have a problem. There has got to be an app that you are using that is destroying your battery when idle. If I don't use my tablet all day, it will last 2 full days (with wifi kept on).
That's what I was thinking. I get a decent amount of usage from it; it's when I'm not using it is when I feel like it drains the most.
I started freezing apps last night and let it charge overnight. I've still got to go through my apps and remove a few I don't use, and check to make sure they're not syncing too often. Do you all leave your gps and wifi on all of the time or have them shut off while the tablet sleeps?

My settings are to never turn WiFi off and I always leave sync on; I like getting notifications and app updates. I have a weather app that updates every hour and Pulse news that updates every 4 hours.
I also always leave my GPS on, but there aren't many apps that use it while it is not in focus, so I rarely ever see GPS pop up on my battery usage list.
I do not use a live wallpaper.
I found that with wifi on, my tablet drains about 1.5% per hour when idle.

I suggest other than setting wifi to turn off when screen is off is to use a wifi toggle widget. You really never know what happens when the screen is off if your wifi is really turning off. Wish it was built in to the quick launch though like some Honeycomb tablet.
You can also use setcpu to setup profiles so that when the screen is off the processor stays at a slower speed rather than jumping into high gear when something wakes it up to sync. I've been able to go days without having to recharge (but I only use it for reading books, listening to the music I have on google music and play order and chaos every once in a while). I havn't touched my a100 in about 4 days and its sitting at 62% battery power.
Sent from my MB860 using XDA App
here is my usage, I never turn off wifi no profiles
I don't necessarily think you need to remove any of the stock app. My wifi is set to turn off when screen is off, GPS off unless I need it (apps like facebook will use it when you open it since it tries to get your location for checking in even if you're not checking in). Gmail is left at default but other mail is set to never (I just manually sync it when I open it).
If you wanna go a step further, you can install a wifi on/off widget to completely turn it off just incase an app is trying to use wifi.
With my setting my battery drains about 1-1.5% an hour when screen is off. IMO the screen is what uses the most battery. However though after conditioning the battery for 3 cycles it's been lasting longer.
I was just about ready to return / exchange my a100 so I did a factory reset on it. Lost track of time and forgot to, so I just decided to boot it back up and play with it. Left it alone at around 70% yesterday afternoon, came back home at 7pm today and to my surprise it was at 40% battery remaining. Must've been an app or setting I had that was killing it.
Probably end up hanging onto this awhile longer. Great tablet for the money!

Also can freezing apps brick your tab as well? Or does it defrost itself after boot?

I think with the 1gb ram on our device there shouldnt be a need to freeze any app and it doesnt defrost itself on reboot. Atleast it shouldnt.
Also I found for the most part if an app can be deleted it will let you delete it by dragging the app icon in the upper right in the app drawer. This is probably the safest way to delete rather than doing it in root explorer or TU.
This might be a dumb question but is it possible you have wifi issue that i've had on 2 a100s which will prob cause it to use more battery as its trying to work harder locking on.
It seems for the moment my battery issue was resolved with a factory reset. I have nearly the same apps on it now as before and my a100 hasn't been dying overnight. Don't believe I've frozen anything this time around either.
I don't think ram has a whole lot to do with it. I just figured some of these apps were starting themselves or syncing often, causing the battery drain.

Do you have a lot of widgets that requires syncing like youtube, twitter, weather, facebook? Those are the apps you probably what to check. OR you can just turn off wifi if youre not surfing or streaming.
Here's mine with wifi turned off. It was at 89 but I had to turn on wifi so I can find a screen capture app in the market. I have lots of apps including facebook, twitter, weather widget, which cant sync cause the wifi is off. Have not removed any stock app. I know this doesn't really answer what you asked but I'm just thinking something else might be wrong other than apps. Maybe its your battery not holding correct charge. Have you tried calibrating the battery?
I tried calibrating the battery the first time around. This time (after the reset) I haven't done anything special and have so far been getting 2 days of idle/light use before needing a charge. Satisfied so far. I was mainly concerned that I wouldn't be able to go on a trip without it needing a charge while sitting in my bag for a day without use.

How can I track down my battery drain?

Leaving my OP in place, but I have rewritten the description with much more detail and pics here
http://forum.xda-developers.com/showthread.php?p=25401417#post25401417
I suggest skipping to there.
I am looking for general tips here. E.g., not asking you to diagnose my specific problem so much as give me ideas of what else to check or try.
Lately I have had unexplained (to me) battery drain. Yesterday I lost about 25 percent in an hour while the phone idled. It is not a constant thing, though. I can go an hour and loose 1 percent then loose massive amounts in the next hour.
Now, i have searched, but I have not found anything that applies to me.
I have:
Tried a different radio
Tried a different kernel
Reflashed my rom
Phone is entering deep sleep according to cpu spy
There are no unusual or excessive wake locks according to better battery stats
No apps are using a lot of battery.
I am in a low signal area at work, but putting the phone in airplane mode and dissabling background syn does not stop the drain.
Ideas?
might be your phone is loosing signal? i would check the battery stats in the settings menu to see if you have a poor mobile signal.

So I don't think I can blame it on that.
Do you have any exchange sync on your phone?

can you give us screen shots of battery stats?

I do, and on reflection it is a possible culprit since I added it recently.
Didn't occur to me since it was producing no wakelocks and the battery stats did not showing as using much battery.
I shall turn it off for a bit and see if that helps. (unless there is some other way to test if it is the problem first.) I am off to the search button!

This is from yesterday when i set it down unused for about 90 minutes. The amount of wakes seems liek a lot, but it is similar to what i see when i have far far less drain, so I don't think that is the problem. I didn't get the app list screen, but out should screen as the only major drain with about 2 minutes.
I know it is shows poor signal strength, so immediately after that shot I put it in airplane mode, turned of sync, and rebooted. The battery continued to drain and graph had the exact same slope under those conditions. (Forget to get a pic though.)

System panel paid version with monitoring enabled is the best for tracking apps using CPU.
OK, still working on this.
To recap:
When the screen is off, and no apps are running I sometimes get inexplicable battery drain. This is occurring under conditions when I should be experiencing little or no drain at all. I say this becuase:
The screen is of and no bakground apps are running
the phone is NOT awake and IS entering deep sleep (as confirmed by cpuspy)
there are no unusual kernel or partial wake locks
there are no apps listed as using unexpected ammounts of battery
This is not a universal problem. The phone *often* behaves as expected. I can leave the phone off for an hour and see a 1% or 2% drain, and I am happy with that. However, sometimes, randomly, it goes nuts on my.
This graph from a few weeks ago shows what I mean. Look in the green box. The phone is sleeping, and the screen is off. The graph starts as a flatline, then, all of a sudden, it begins to drop precipitously.
Here is a graph that shows the battery dropping at the same rate whether the phone is awake or sleeping:
I have gone the following to try and narrow the problem down:
Done a completely fresh install of my Rom including a system wipe.
Tried two kernels (the aokp default and several relases of Franco's
Tried a different radio
Activated and installed a new sim card
I have come to suspect that the problem is network related. When the problem starts, sometimes going into airplane mode and back and/or toggling 2g only temporarily fixes the problem.
I suspect that something is happening with my connection to T-Mobile that keeps the network running and draining power. This is pure speculation, but it is all I can think of.
I installed juice defender (which I had not been previously running) and noticed the that, sometimes, it didn't turn of data when it should have. I also noticed the following two things happen:
I do not believe it is a rom problem, since if so, someone else would be reporting this. It might be an app problem, but if so the app is draining battery without a wake lock and while the phone is in deep sleep.
It is not exchange (as was suggested in this thread) since it continues when I ev my exchange account.
I have no idea what else to do or try.
Since it happens at random and takes a while to identify, uninstalling one app at a time to test for that could easily take months to narrow down a misbehaving app.
I know it is not a hardware issue since last month I got this:
That was with AOKP and Franco (earlier versions obviously)
I have google searched till my fingers bleed.
I am a long way form being an expert, and I suspect I may have overlooked something obvious.
Please, any thoughts??
Damn you definitely have a major issue and I don't know what it could be. But when my phone sleeps itstays dead flat with no awake bars, and drops 1% every 3 hours.
1. Calibrate battery
2. If you really wanna find the problem, install the rom with no mods or apps and run it and see if it still happens. Then add back each mod/app one at a time

While I appreciate your effort, this is remarkable unhelpful for the following reasons:
1. "calibrating" the battery is a myth and doesn't actually do something. Even if it did, it would not explain the symptoms I have described. I have been around xda long enough to know it is the knee-jerk reaction to any battery question, but it is not relevant here.
2. Since the problem occurs at random, and sometimes takes hours to show up, (For instance, last night I charged to full and tried to catch it happening. For 4 hours nothing happened, it behaved perfectly. Then I went to bed and it immediately started to fall and was dead by morning) and since I have over 100 apps, your suggestion could easily take *over a year* to follow. Believe me, I have thought about it, but I started this thread hoping for ideas that would allow me to avoid it.
Here is that chart for last night.
I had about 1 hour and 30 minutes screen on time with 65% left when I went to bed. When I woke up, phone was dead.

Mine often does that. But sometimes it doesn't. It is the fact that it happens seemingly at random that makes it so annoying and hard to track down.
I would replace the battery
One thing you haven't rulled out is that the battery itself is bad.
Have a friend you could swap with for a day, or at least long enough to see if the problem follows? If your battery drops on their phone that is also a good indication.

The thought has occurred to me, but unfortunately, no, I don't have a friend I can swap with. And really, since I have had the phone less than 3 months, the battery *shouldn't* be bad, but yeah, defective products happen.
If I cannot find any other cause I will likely order a new battery and see if that fixes it.

1. yes battery calibration does make a difference.
2. ok, so an app can't run a process at random? especially when you have "over 100 apps"? Run the rom stock and see if it still happens, or even run the stock rom/kernel. if you don't want to try this then why are you asking for suggestions? christ

You are incorrect. But, in any case, I DID calibrate the battery just to cover bases in the case that I was wrong.

We'll of course it can. That is kinda my point. If I go one app at a time waiting for it to "run a process at random" I am talking literally MONTHS of testing. I would have to wait many hours, if not days after installing or uninstalling an app to be sure whether or not it made a difference, then move on the the next. This is simply not an option. I started this thread in hopes that a realistic and doable solution might exist that I was unaware of.

I am asking because there may be a solution that I am unaware of that doesn't require me to put my entire life on hold for months. It is possible that there is no such solution, but I asked in case there was one.
Sorry to have put you out so much.
You mentioned you recently installed exchange sync. Did turning off sync remedy this or have you not tried disabling all sync features?
One other thing to check is the background data usage of your apps. You'd find this under 'data usage' and make sure you enable the wifi tab so you can see data usage on wifi.

when i did a complete quote and re flash i did not setup the exchange account, but the issue continued.

My battery also drains at a rate similar to yours however I'm on the CDMA version. Hopefully you can figure out what's going on with yours.

Massive battery drain by unamed app

Hi i was using moto 360 and had a predty good battery life.But from today morning to went from 100 percent to 20 in one hour with no use .In battery stats it shows an unammed app with the defualt icon on android app a green android.Has anyone else experienced something like this and what can i do

Is your phone rooted? No, it's not the reason, but it may help.
Prosecutor: Objection! Judge - relevance?
Me: Your Honor, I have a point.
Judge: Sustained, you may proceed.
Hi thanks for the answer yes my phone is rooted
Cannot in any way connect the root status of the phone (?) to excessive drain on the watch.
First day of using it (got it yesterday) I got about 6 hours out of my watch. I went through playing with everything yesterday already, so not that much action today, only the regular Gmail and Hangouts notifications. Top consumer, as per the OP an unnamed app. I would have expected more from my watch, to be honest. Ideas?
Oh, and got the update notification for 5.0.2 directly after turning it on and pairing, so I'm on 5.0.2 already.
Same here

Hi, i got the same issue since i updated to 5.0.2. I used to get a full heavy use day and still remain 30%40% at the end of the day, after the update i only get 11-12 hours of use. Any help will be highly appreciated.
Note: My phone is also rooted.
I'm not fully through testing/verifying the following, but I made an obervation.
I used the watch the other day and got about 18+ hours out of it. Dont know exactly, just put it on the charger and was happy still having juice left.
The following day, all was going well up until to that moment I started using a timer app on my phone, which counted down at 5 minute intervals and showed a live updating notification doing so. I didnt pay attention to the watch, as the timer is phone only, but as I checked the watch at some point for something different, I noticed the battery dropped significantly since I last checked. Upon checking the battery stats, I found that the charge started dropping at about the moment I started continuously timering.
I take from this, that when using tools which interact with or update your phones notification drawer, the watch will get somehow polled as well. But I am still investigating.
In case you wonder: its an ingress portal hack countdown timer.
Question about settings?

Do you by chance have your dev options enabled on your device that your Moto 360 is connected to? If so, I did a test on my device to see if that was a battery hog on my Moto 360 and turns out it seems to be. Un-named app (android icon) showing the most usage but the graph I have shows upon Dev options enabled, battery began to plummet badly. Just an observation. I perform testing on mobile and wearable as part of my job but I didn't have a way to analyze any logs for this wearable (moto 360). I don't have Moto's log analysis tool.
I do have dev options enabled. But as the watch is now generally behaving well, I don't think it's connected but happened to you by accident. This is only a guess though.
To be honest, I'm on xda with a couple of posts made already, of course I have dev options enabled :laugh: I use plenty of tools day in day out which need dev options. I also on a regular basis manipulate my device via adb, so dev options really is a must.
Anyway, I will observe this some more and get back to this thread in case I find any new developments.
