    I've seen people mention better battery life but is anybody else with VZW experiencing major battery drain on their M9 since the 6.0 update? A few texts and twitter usage on WiFi and I'm down nearly 50%. GPS, NFC & Bluetooth all off, and no unwanted apps running in the background.

    Anybody else dealing with this or just me?

    Only thing I noticed is Wi-Fi seems to drain the battery and also has connection issues.

    By connection issues do you mean the connection stalls and turns off momentarily and turns back on?

    It will show connected and stalls or stops responding. The Wi-Fi always shows connected with no activity. Tried it on two working routers and it does the same thing. Frustrating.

    Not having connection issues, but still experiencing significant drain. Guess I'm alone in this?

    My battery is better since the update. I did install Greenify though. That may be the difference.

    I've not updated because of all of the negative feedback. To those who updated, is the update worth it?

    Yes. Ignore negativity. This is an overall better phone with Marshmallow on it.

    I agree, it helped the M9 overall. I've had no issues and the doze is really good. Unplug at midnight 100% At 7:00 a/m 99 % .

    Does the phone really have to be laying flat for doze to work properly?

    Can you share your settings apps etc...? I unplug my phone @ 5 am and by 9 am it's down to 96%. Keep in mine Wi-Fi (connected,great signal), excellent cell phone service (full service) mobile data on along with Wi-Fi but disconnected until away from Wi-Fi. Location:battery saving.

    I think the key is it can not be moving. Set on a table it will doze but not in your pocket.

    This is silly. Google think they're so clever. So if the phone is in my pocket and I'm not using it everything on the phone is going to be awake causing the battery to drain even though I'm not using it.

    That is my understanding. Because the gyro senses movement.

    I've had battery issues as well since 6.0 was installed. The phone is fine in general until I start texting. Texting now seems to be a significant drain on my battery. About 1% usage for ever 3-4 messages sent/received. Using other apps don't have the same affect on battery life.

    I'm definitely having both issues since the Marshmallow update. Significant battery drain and really poor WiFi performance...both Chrome and Dolphin Browser seem to have issues loading pages over WiFi. Phone also gets hotter than ever too. Anyone have any recommendations for fixing either of these without rooting? My employer won't allow rooting.

    I know this is a Verizon forum but has anyone noticed that the mobile data sleep option is removed since mm update?

    I'm also having issues with battery drainage since the update. I've tried to pinpoint it with Gsam and the native battery usage app in the settings, but really can't figure out what is running.

    I read somewhere that scanning Always Available" option has been moved to Location->Menu->Wi-Fi Scanning. Maybe this would help.

    I had an issue with my T-Mobile M9 draining 30% of power in 6-7 hours (when I was asleep) with all apps closed and the phone restarted. I got fed up with the power drain and factory reset the phone. Since that factory reset, the battery life has been amazing. I now lose about 3% of power in that time frame. I also noticed after the factory reset, the home screen locked changed. Not sure why that is as I had updated my phone's apps fully prior to factory resetting. Factory resetting is probably not what you want to hear, but it worked for me.

    Definitely don't want to hear factory resetting. I've been doing some tests and noticed my battery issues are most prevalent when I'm connected to my company's wi-fi. I think the fact that there are numerous access points throughout the building that the phone may be getting bombarded on staying connected to just one. I mean there is an access point in every conference room and one about every 30 ft in the actual office space.

    I know the other battery issue is Candy Crush. That game eats an insane amount of battery as compared to streaming video. I get almost 2x the battery life streaming videos then I do playing that stupid game.

    Is this normal: I have been using my phone for just over an hour for internet browsing and social network apps and the battery has dropped 14%.(Wi-Fi + battery saving location).

    I have a feeling my battery drain has something to do with this. The OS thinks there's no signal and probably using more power to transmit. Anybody else see this on their phone?
