Stock Doze & Gmail

I'm currently on stock MM vs985 and am curious to know a little more about how Doze is supposed to work by default. I get the concept, some apps will spam you with notifications and drain your battery in the process, so those are kind of put on hold while others are "priority" notifications and get delivered immediately. The user also has the option to give specific exclusions from Doze so the notifications will get delivered immediately as they have in the past. At least this is my understanding of things.
The reason I ask is because Gmail notifications aren't quite right. When I'm actively using my phone in the morning, they seem to come in normally and Doze doesn't seem to be active (which is expected). Then when I go to work Doze will kick in and I notice I don't get as many Gmail notifications, which is fine. However on breaks or over lunch, I actively use my phone again. At this point I would expect Doze to no longer be active and I would think the notifications that Doze delayed would start showing up (granted maybe after some delay, but at some point over an hour lunch break). Today after work I didn't have any Gmail notifications so I opened Gmail, it showed the most recent email as one from around 11:00, I swiped down to refresh, and suddenly five more emails showed up (11:38, 12:01, 1:01, 2:59, and 5:40). With that many emails at those different times, I would have thought notifications would have came in at some point without me manually refreshing my emails.
I realize I could exclude Gmail from Doze, but I don't really need the notifications immediately and I would like to get the battery saving benefits of Doze, I just don't get what it's doing or why. I would assume Doze would DELAY notifications until later so they can be processed as one group/batch, not STOP them completely. Is this correct, is there possibly a setting or something I should be looking at?

don't want to sound stupid but do you have greenify installed? Do you have sync turned on?

No greenify or any other non-stock battery saving apps, and yes sync is on. Lunch break and no notifications but I bet when I manually refresh in gmail later I'll have emails that should be coming in now :/

49 hours estimated time remaining for my battery, so it's definitely saving battery, but I'd kind of like notifications when I am using my phone :/

Break time at work, still no gmail notifications. One thing that I realized was that I did have a notification from Facebook just now. Does this indicate that either the Facebook notification has bypassed Doze (made itself priority) or gmail notifications specifically are being blocked by Doze?
Also, when I woke up this morning I did have gmail notifications waiting for me, so that means the normal sync process is capable of working correctly. I had my phone on the charger overnight, so Doze wouldn't have been active (which explains why the notification came through).

About 45 minutes ago I finally got gmail notifications for 6 new emails I got throughout the day. Not sure if it's relevant but this would have been about 10 minutes after I got home where I would have been back on wifi since this morning. I also noticed I have Facebook notifications, and the time on the notification is about two and a half hours ago, so I don't know why the gmail notifications wouldn't have came through at that time as well.

So with all of the knowledge and skills around here, no one has quite fully figured out the stock Doze functionality?
FWIW I don't seem to have this same issue on custom ROMs, at least not on Resurrection Remix.

Phone loses certain settings or apps if the battery dies suddenly

I have searched as much as I can, but can't find any info on this. It has happened on both mine and my wife's M8, but only after updating to Marshmallow. If the phone dies suddenly without being able to shut down fully most of the time it will lose certain settings, like sounds, data and Wi-Fi turned off, saved Wi-Fi networks gone, etc. If it happens while starting up it has lost whole apps, all contacts; mostly acting like a first boot but some installed apps, settings, call history, text messages, etc did remain. Any ideas?

I spend the same, and also turns off me having 20 % battery....google traslate, sorry.

I get the exact same issue, but no idea why it happens :/

It's a glitch with HTC's Marshmallow version. It happens on stock as well as custom ROMs. Nothing to do but wait for an update from them, or always make sure your battery stays charged. It happens to me at 6%

Same Problem but phone dies at 20%-30%

I am having the same problem, heaps of settings change, including default keyboard, messaging app quick settings wifi etc
if my phone was dying at 5%i could deal with it but it is dying anywhere between 20 and 30% and often catches my unawares.
An update to fix this would be great.

Yup, I have the same problem only I don't lose saved wifi networks but I get signed out of every single app. I also get a google play services error which requires me to clear the apps data.

Snap!
I have been having these problems for the past 4 months (running Lollipop)
I thought that the Wifi passwords issue and app logouts was due to low system memory. (battery would die around 15%)
Since doing a factory reset and 2 weekends ago, the battery dies around 25% and I still experience app log outs etc.
My device is close to the 24month warranty limit and I need a fix urgently.
I also have Bluetooth call random clipping happening both on lollipop and Marshmallow.

This is killing me. Any fixes yet?

Lately it's been losing home screen icons and a couple settings even when I manually shut the phone down. Ironically yesterday when it died suddenly some previously missing icons I had yet to restore reappeared.

please!! any Fix ???

Any fix??? My phone does this too, and its becoming more often than a weekly thing now

A few times now manually shutting the phone down before the battery dies has led to all Google related icons (Chrome, YouTube, Play Music, etc.) being removed from my home screens and having to manually re-add them. When the battery dies it's a roll of the dice what, if anything, will be changed/lost.

In addition to almost everything already said RE: most customization is lost, apps and widgets disappear on restart, etc. I've noticed that all of the (mostly AT&T) apps that I disabled are enabled and updated when the phone comes back on! This is so annoying and is my first major problem with this phone! It's taking time to have to redo all my settings each time the phone dies!

Same problem here very annoying especially as I have to phone bank to reset my mobile banking app as it screws the settings in this. #leaveitoncharge

Yesterday mine died at 30%, and upon restarting it went through the "Optimizing Applications 1 of 261" then proceeded to come up with a warning that the phone had an internal error and might be unstable until doing a factory reset. After clearing the warning it was stuck in a "Sense Home has stopped working" loop until I could get into Settings and clear the data for Sense Home. This allowed me to at least make sure things were backed up before doing a factory reset, but more than half of my contacts were missing as well as many text, call history, etc. A similar thing happened with the wife's M8 last week and had to factory reset hers then too.

I had this problem and had my battery and main board replaced in the final month before 24 m warranty ran out.
Do a battery test *#*#3424#*#*
Then hit more, and select battery test.
Battery has to be 100% to complete teat which takes an hour. Do this when you don't need it.
My test would often show 91-94% but I had one that said 71% which I saved a screen shot.
Since the battery and main board replacement it's still my favourite phone.

solve the problem of battery and loss of settings , change the battery of my htc, now everything is fine , 3 days that the battery is discharged properly , I hope this information will help someone.

Not positive I've lost settings, though I'm fairly certain I have. I have lost app permissions many times. And my phone seems to die around 30% and won't let me boot unless I am plugged into charger. I was recently forced into a factory reset due to a message that popped up just like a somebody else a few posts back. This is a recently replaced phone (VZW replaced it as the prior had battery problems). The prior one did not do this. I hope HTC get's their act together and fixes the issue. Highly annoying.

Ive been having this issue since the beginning of the year and now it seems to happen every few days. I pretty much don't have a choice but to buy a new phone at this point, which sucks because I love my m8.

This is exactly the same issue I've been having. I'm at my wits end with having to re-do all of my settings and apps daily, and sometimes (randomly!) it won't hang onto a charge for more than a few hours even if I'm barely using it. I basically have to leave it on a charger all the time to keep it from shutting down and losing all my settings! I used to love my M8, but for the first time ever I'm considering swapping to a Samsung just to get away from these issues. I've had this phone for a little over two years and these problems only just started around March 2016 - but they've been an absolute constant since then, and only getting worse.

No notifications while on standby. Bluetooth constantly turns off. What gives?

I got my Pixel XL (unbranded) earlier this month, and as much as I wanted to love the phone, two consistent issues keep happening which are making me despise it.
The first issue is my phone refuses to retrieve Push notifications while it's on standby. I will get no notifications from any app until I physically wake my phone. As soon as I pick the phone up and turn on the screen, BAM, a billion notifications. This is true even for Google apps like gmail and hangouts. I have seen lots of threads on this subject dating back years for various devices, and none of the 'solutions' fixes my situation. Battery Optimization isn't on, and even when I toggle it on and exempt all my apps, it still does it. IPv6 is disabled at my home network level. I disabled the Connectivity service. I enabled notification importances and set all apps to high. I turned off WiFi while on standby. I begrudgingly did a full reset. Nothing has worked.
The second issue is related to bluetooth. I cannot get it to stay on. It turns itself off whenever it feels like, so whenever I get into my truck and expect my GPM to start playing, all I get is "The bluetooth stereo device is not connected." I take pride in my attentive driving, which means if I forget to reconnect everything while still in my driveway, I now have to pull over just to get some tunes playing. Getting infuriating...
So, I'm at my last nerve. I turn to the Gods of XDA for your advice before I return this thing. Is there any fix to all this? I'm not opposed to rooting or using custom images. I just want my phone to work.
Thanks in advance for any info you can provide.

Google is aware if the Bluetooth issue, the Feb update caused it. They are working on a fix.
I got nothing on the notifications. Gmail doing that is quite common and goes beyond the Pixel. Never heard of anyone having issues with other apps.
You running any doze programs or task killers?

It wasn't the Feb update. Bluetooth got bugged in the 7.1.1 update for me personally.

No, the phone is pretty much stock. I have Skype and a couple games on it, but nothing that would interfere with network connectivity while on standby. Just to be sure, Doze is Battery Optimization in the settings, right? It's default to off, but after experiencing issues, I turned it on and exempted all apps. Didn't work, so I turned it off again.
I've never had this issue with GMail. The latest I have ever been notified of a new email from gmail is about 5 mins. Now, I go hours without them up until I wake my phone. And again, this is for all apps that have actual push notifications. I'll pick up my phone, then get a slew of new emails, skype messages, hangouts, etc...

Apps not updating when phone not in use...

Has anyone else noticed this? I've noticed it with the Gmail and Youtube apps specifically but it could be happening on other things and I've just not noticed. If I have emails and delete read them on my desktop then the notification doesn't clear on my phone and notifications for YouTube subscriptions appear when I unlock my phone. I don't think it's happening 100% of the time, I have watched email notifications clearing when I clear the emails on my desktop but it's happening enough for me to notice and make this thread. Power mode is on high performance, pretty sure it's all set the same as my Note 9 was, so is this another niggle that an update is going to sort?

Battery optimization settings?

That was my initial thought but it's configured the same as my Note 9 was and I didn't have any issues with that.

Something not quite right here. I woke up to no notifications for Gmail so I've disabled adaptive battery for it and it's still hit and miss with notifications.
No one else at all getting these issues?

Mine was doing something similar and the battery optimisation setting was turned off so I delved into gmail settings and found that all of the labels that I need notifications for had been set to No Notification [emoji15][emoji848] so I turned the notifications back on for the labels and it works just fine now [emoji6]

Yes, I do experience the same issues. I've checked the notification settings and battery optimizing settings multiple times. It is exactly the same as my Note 8. My Note 8 displays the notifications directly while my Note 10 doesn't.

At least it looks like it's a Note 10 issue then.

Yes I seem to be experiencing the same issue. Thought it was odd I didn't have any gmail notifications and went into the app and all the emails came in.

I can feel my sanity returning. I even did a full wipe yesterday and set it up fresh instead of the smart switch I did originally and it's still doing it.

I swear it's getting worse which makes absolutely no sense at all. Before it just occasional times but now I'm having to go into the app every time to find emails.

Talking to myself now but...
I had the Samsung Galaxy Tab S6 arrive today, they're sat on my desk side by side, the Tab is getting Gmail alerts and my Note 10+ isn't.

Have y'all looked at Don"t kill my app - Samsung?

I tried turning battery optimisation off for it and it didn't seem to make a difference.

Same issue here with Gmail notifications. Checked all the options. It was working before the security update though I'm not sure if there's correlation.

Same here with Gmail.

Same issue.
I don't get push notifications with gmail app as well.

Seems like the culprit is the Note 10 in this situation.
However try another email app and see if the problem exists.

Randomly started working yesterday perfectly and then stopped again.

Same issue. No Gmail notifications. App only refreshes when I open it.

Same issue. Turning off battery optimization does not help. Only seems to be happening with gmail for some reason.

Notifications Issues

I know this will be almost impossible to solve with suggestions, but some of my notifications don't come through until I unlock my phone. Most notably WhatsApp. I've turned off all battery optimisation options, removed it from the sleeping apps list, allowed background data and turned off data saver. Still have the same issue.
I have naptime installed so turned that off as well.
What's strange is that a few days ago all my notifications started coming through as normal for a few hours, and then stopped again.
I know the only way to solve this is probably a factory reset, but with loads of tweaks I've gotten it so my battery life is amazing. Leaving it overnight it drains around 3% and depending on how I use it I get around 8h of SOT with 50% battery left so I don't really want to factory reset.

What launcher are you using?

I feel your pain with factory resets.
There needs to be a backup settings to cloud so you can easily restore them after a reset or even a change of phone.

I understand your frustration with this issue, I experimented it as well when I started using my device, back then I did not fully knew about all the battery optimization settings, but, when trying to get all the notifications right, I stumbled upon an app named PNF-no root, which is meant to fix the push notifications from sms, email, whatsapp, etc, I tried so many things, that I honestly can not say if this PNF solved the issue, but in the end my notifications became normal, so, I kept using it, you can give it a try, that is, before you reset your phone, it might help

Do you at least move your phone? Because a lot of apps, to bypass the system's optimisation that put apps to sleep, is that their wake up workaround is gyroscopic based.
That's why WhatsApp and such use a lot the sensor while it has nothing to do about in the first place.
If a battery monitor works for you, you can check that for WhatsApp.

Yes I've got it on me all day. It's never left anywhere for extended periods of time.

I've just installed a push notification tester app and my phone goes into doze immediately once I lock my phone and the screen turns off it seems.
If I request a notification, it comes through with the phone unlocked but if I set a delay of a few seconds and lock the phone before it comes through, nothing will happen until I wake my screen up.
Any ideas on how to solve this?

I worked out what the problem was!
I have a VPN that is set to disconnect when my screen turns off to save battery. At the same time I enabled the Android setting that blocks all connections without VPN. Of course when the screen turns off and the VPN disconnects, my phone was blocking all outside connections, hence me not getting any notifications.

Well, I am glad you figured it out
