    Update on mine too. I rolled back to 8.1 then updated to 10549 and my battery is basically as good as it was in 8.1 now. I'm on an HTC M8.
    Can't say if it was the clean install, or 10549, but I'm much happier now.

    I feel ridiculous saying it, but I think my battery life on my Icon may be just as good, if not better, than it was on 8.1.

    The messaging app can still consume a decent amount of battery, particularly when MMS is happening. But on the whole, battery life is significantly improved with this build.

    I was one of the first to proclaim how clean and crisp this build appeared to run on a 1520.
    But it wasn't long before I took a huge hit on the battery. Something that huge phone normally is immune to. :)

    Sure enough, it was the messaging app. The only thing that seemed peculiar was that it was struggling with downloading all my historical texting from the cloud. (native text-backup is one of my favorite aspects of Windows phone. So easy for changing phones or performing hard resets or loading preview builds!)

    Never experienced any difficulties syncing texts with previous build(s). So I did a hard reset to see if it was just a glitch. But alas, it has been hours and my texts are still "trickling in". I have a couple of years worth, admittedly about 800 megs. But it has always just successfully synced without drama, heat, or constant battery draw.

    Otherwise, still a sweet running build. :)

    i charge my phone at night, and battery has been good so far on my 930 with build 549. Then yesterday, at 5pm (9 hours on battery) my phone was at 60+ %, 5 hours later I got a sms warning me about my data plan is at 80%, my phone was hot and I had 17% battery left. I put it on my nokia qi charger and 1,5 hours later I have 18% battery. Soft reset phone and when it boot up I have 21%. I let my phone cool down then put it on usb charger for the night.

    So I wake up today and my phone is cool and all fine, an hour later and an alarm goes off and my phone is hot, I have lost 25% battey. I check battery saver and it says messenger has used around 50% battery last 24 hours. An hour later and I'm down to around 40%. I turn off the phone and turn it on again but it does not cool down. So I turn the phone completely off wait for it to cool down and turn it on again, now the drain seems to stop.
    Also now when I check battery saver, messenger is far down on the 24hour list !! WTF

    There is no option to uninstall the messenger app. This is not the skype preview version, but the one that comes with current build. I did a complete wipe after installing latest build. What to do ?

    it's actually draining faster than QI can charge now :(

    Yesterday I noticed I have the same issue with the messaging app, consuming more than 50% of my battery in the last couple of days (mostly for background usage).
    Soft reset wasn't a solution for me; probably I should hard resetn the phone but I hope for a quick fix / work around before it becomes unbearable :|

    The messaging app is the only issue I am having with the battery life when it acts up. Twice now I have had the phone become warm and it start to drain quickly. Not sure how I got it to stop, but one time I swear charging it caused it to come out of its problem.

    I had 3 hours of screen time this morning burning only 35% battery between the different applications I was viewing and some music playing. Using HTC One M8.

    I did a complete wipe, reinstalled everything - not from backup. Charged the phone to 100% and went to bed. When I woke up phone was off and battery drained. I've noticed on my W10 Desktop TP there is a proccess "Unistack Service Group (4)" gone bad and using 100% of one cpu core, maybe it's related, some background task gone bad.

    Updated yesterday 22 core apps on my 520, and suddenly the phone stopped overheating and battery draining!
    Then I checked and polished the sd card using a pc (last build seems can't checking sd by itself in case of problems!) and apps on it opens faster and doesn' crash till now

    Only main iussue forn now, sms doesn't notify on lock screen... again...

    Messaging ate up to 30% of global battery use. But then it was because I was restoring 2 years of SMS (^_^) and dub403-m hotmail server had glitches these days. So I guess it was constantly trying to fetch messages from the server.

    Now everything is back to normal and no unusual battery use from messaging.

    So it is possible that the server that hosts the cloud copy of your 2-years of historical text was the reason it took so looooong for the text messages to repopulate the messaging app?
    I totally believe it was the culprit for my battery drain as well, but I assumed it was something on the client-side (this build) that caused the unusual struggle. I too have 2+ years of texting that must sync each time I deploy a new phone. But I've always been impressed with how efficiently it has succeeded. Love the fact I get my text history even with NOT choosing to restore from a backup......something I avoid so that I can get the cleanest install possible.

    Anyways, this build is behaving very well on a 1520 once it overcame the strenuous text sync. Battery behavior now is really good.

    This is a fact the dub403-m.hotmail.com server had hiccups between wednesday and saturday morning (Paris time). My 1020 had also difficulties to sync my MSA account some times in the same period ; on the 640, sending/receiving mails was difficult or impossible with errors returned from that Outlook server.

    And because it was restoring SMS, I think it drained a lot of battery to try and retry. It was restoring well before my first reboot and then, MSA account issue. I've hard reset 3 times, each time the same scenario.

    Since then, everything is fine, battery life is excellent, messaging has returned to normal, etc.

    FYI, dub403-m is located in Ireland, so if you're in Europe, it may be your server too. It's not rocket science : the 535 upgraded to latest build had no issue at all for instance.

    I had a different issue (had to go back to 8.1), because I only sync last 30 days and it was done instant. Also my battery drain problem started after 2 days working normal, started friday evening and continued until sunday morning (CET). So if the server issue was resolved saturday morning, why did my battery drain from 100% to empty when idle during sunday ?

    I'm not saying only a server issue is explaining the messaging drain. But ms have different servers, maybe yours was down when mine was up etc. If there was a server issue, you should have received errors when syncing your mails too I suppose.

    Hate to dig up an old thread, but YEA!!! Messaging app is sucking the life out of my battery on my Lumia 810. Seriously, I've had 4 consecutive days where I take the phone off charge (100%), and in 2 hours I'm down to 30%.

    Also, I'm randomly not getting notifications of new SMS messages. I have to make sure that after a receive a couple of SMS messages, that I have to completely exit the app.

    Try to disable (log out) of Skype services, using skype video app I believe. It seems many people had problems with skype part of new messenger causing battery drain. I've not had this issue since 10549.

    I just disconnected Skype from messenger via the Skype Video app, and installed the Skype app today. So I'll have to see how it turns out.

    it has more background usage than normal usage, yea that's definitely faulty software, same with the photos app, I had to block it from running on the background, I cant do the same with the messaging app, I mean, I could just as easily get a feature phone then, what would be the difference

    that one is equally bad, and one of the reasons I wanted to try w10m asap :P but it doesn't ruin your battery unless you use it(which sounds logical) and if you have an amoled phone it will be even worst

    Ok, this is just weird.

    Last night I had 97% charge. I put my L810 on the chi wireless charger like I always do. Woke up and picked up the phone, and it was down to 3% charge. I'm at a loss as to why now.
