    Overheating?
    Did it turn off? If not, it's not overheating.
    My 950 got hot and had battery drain for about two days, but it was also loading backups, downloading/installing apps and processing 120 GB of media from the microSD.

    After the phone stabilized, it cooled off and the battery got a lot better.

    Try turning on Battery Saver and see if that helps.
    Does battery saver mode really help or hinder?

    I'm on battery saver, pretty sure it's having zero impact. My phone has been off the charger for less than a half hour and this is what I get...




    So 6 hours of battery life at best? With battery saver on? Pretty sure my battery has gone to ****. Who do I contact now, AT&T or Microsoft? I got the phone launch day. AT&T does 30 day warranties right?

    This has been discussed to death, only the XL has liquid cooling. Here are FCC pics of the 950 in various states of disassembly. Click on Internal Photos and tell me if you see a heatpipe.

    yup, we have all seen it discussed to death. everyone seems to be pulling stories from the MS announcement event, which did make it seem like both 950's had liquid cooling.

    Also, with the term "overheating" being used, it's driving me nuts. does the 950 get hot? yes, yes it does. is it overheating? probably not. if it were, i am pretty sure a few 950's would be totally dead by now. running hot doesn't equal overheating.

    Wtf! 4 hours... That's insane, I think either the battery isn't settled or you have a defective unit. I unplugged mine at 6 am and been using it normally and I'm at 70%.

    I was having battery issues with my ATT Lumia 950. I tried soft and hard resets to no avail. Finally, LumiaHelp on twitter suggested Windows Device Recovery Tools to reinstall the OS. It took about 22 minutes for me and my internet connection. Afterward, I restored from backup, updated the phone to the newest build (10.0.10586.29) and like 50 something app updates. My battery went from 100% to 85% for the whole process and only got slightly warm. A vast improvement over what I was experiencing. My phone charges properly (8% to 100% in 45 minutes) and doesn't just get super hot. I went from about 40% to 25% over about 7 hrs while sleeping with glance screen set at 30 sec, Bluetooth and wifi on, a few emails during the night and my alarm set. While this isn't stellar, its a vast improvement over what it was. A few more days of testing should give me better results.

    I noticed edge has a habbit of loading every page as a tab sometimes. When edge is using up a lot of battery go to the tabs button and close everything. I had 50 tabs open at one point when I looked.

    My second Lumia 950 seemed better for a while, but lately, I've had the same issue. It was not any of the reasons mentioned below, regarding background programs etc...

    I'm fairly certain that the issue is directly linked to the SD card usage. I've tried 3 different memory cards, to no avail - I have MASSIVE overheating and battery life that drains about a percent per minute. There is DEFINITELY a problem with the 950 and some, if not all, memory cards.

    I've used a Sandisk 64, 256 and a Samsung 128 card.

    changing the subject slightly... I have an old DT-900 that I got free with my Lumia 1020. I never used it until now on my 950. and so far its taking a long time to get to 50% from 14% (over 2hours). Is this normal? Also finding the 950 to be getting very hot! The glass is quite hot to touch?

    is this charger ok to use? is this normal behaviour? would I be better off with a new DT-903? in that would it be quicker and cause less heat?

    My main concern is its hot for over 2 hours already, if I was quick charging with the wall charger it would only be hot for the first 40 minutes?

    with regards to all comments about I'm finding my unit to be running very well. pretty much no heat unless charging and battery usage is around 40% per day

    Well I am no specialist, and I am definitely not the best person to compare your Lumia experience too, but I do think I pinpointed where my problems are occurring on my second Lumia 950 xl.
    So for a while now I experienced like a lot of users that the 950 xl would warm up. Sometime it would warm up a lot. When it would warm up a lot I found out that some of the old apps that I was using were not compatible with this version. So I reinstalled the phone, and only installed apps that could be found in the app store and stated they would work with this version. I noticed in the days following that it would get warm but not so warm anymore that you could cook an egg on it.
    I then started to look into the problem why it still kept getting warm. Even though I was not doing anything strange or questionable. After going though a lot of forums I still could not figure out what the problem was. As suggested I went through the battery save and found one thing strange. My messaging was taking up at least 40% of my battery during a 24h period. Went and did some research on this and found out that the e-mail was having problems syncing. As soon as the syncing problems were over the phone would cool down. Have tested this theory several times and as of this moment it has been true to all my warmth and battery life issues. Solve the sync problems and battery life goes back to normal (meaning it is not drained in a few hours) and the phone no longer gets warm. Maybe this will help some of you to pinpoint your issues with the new and wonderful Lumia 950 and 950 xl.

    That's some good research on the email sync issue. Between waiting several days for things to settle down, moving apps from the SD card, deleting incompatible apps and looking into email sync, hopefully most 950 owners will get decent battery life.

    My DT-900 from my Lumia 920 did the same on my 950XL. Some people say this happens when the phone isn't aligned right, and others think that there's some runaway process that using power almost as fast as the charger can provide it. I think charging circuitry is also designed to slow charging if the battery gets hot, so maybe a combination of high CPU use and reduced charging rate due to the temperature? If anyone ever really resolves this please post, because I was also worried that it would be bad for the battery. Batteries degrade when they get hot.

    To test this, I set Outlook to only check for new messages every 30 minutes. Didn't make any difference. Everything syncs fine.

    I decided to completely reinstall the operating system using the recovery tool. Observations:

    1) The process went smoothly. I was able to use a recent backup to bring my phone back to where it was prior to the reinstall with no trouble.
    2) The process caused virtually no heating issues, or battery drain. The entire process took around 25 minutes and the phone didn't get warm at all.
    3) Reinstalling the apps, which is automated, took around 45 minutes. I didn't have the phone plugged in, and there was no significant heat, nor battery drain. The process used 2% of battery life (it was 98% when it finished).
    4) I did the entire process with no memory card. After a few days, I will reinstall the card and report back. I am convinced that the memory card has something to do with this.

    Other observation regarding memory card:

    The memory card can be removed / installed while the phone is on. Installing the card causes SIGNIFICANT heat almost immediately, and it doesn't go away. I only have my new Samsung card to try this on. This is prior to re-installing the operating system; I haven't tried adding the card back yet.

    The phone is now running cool, which it had been for a couple of weeks prior to it overheating again, as per when I first purchased my original 950, and started using my second 950 prompting the initial post.

    I think there is a correlation with the device heating up and the constant data connection the device is trying to connect. I noticed once I turned off Cellular Data the Lumia 950 runs cold as a rock and battery life improved when running over WIFI. I also noticed that the arrow next to the cell reception is constantly on and I see it drain the battery. What is also weird is the arrow still continues to go on and off in minute intervals even when cellular data is turned off??

    Sounds like my issue - fine until 10.0.10586.0 and then running hot with all background apps turned off. Battery life around 3hours unless airplane mode turned on. Then 6 - 7 hours.

    Gary
    This is an ideal description of my recent battery situation, and gives some added perspective, so thank you. I noticed I was on 10586.0 but hadn't been thinking of it as an "update" (focused more on the fact that it wasn't the latest), since the phone has been working flawlessly for weeks until just recently, and I haven't needed to look at the version. Perhaps my issues all started with a recent update in the background. It's either that, or from my installation of an SD card, and adding a bunch of data to it.

    My Lumia 950 was hot like hell in the first 2-4 days then getting better after 6 days everything works perfect and overheating is gone, I think there were some activities and setup running on background, I suppose in battery settings adjust which applications should run on background this is also eliminate overheating

    I haven't had any heat issues with my 950 -now approaching a month, and have now learned to manage battery-related settings so I can run all day. I have three email accounts all set to as-it-arrives, and I do not use battery saver. My main suggestion is to check your Privacy settings, especially Location and Background apps settings: All sorts of capabilities I don't need nor want, and I turned them off early on. I also deleted active apps I don't need/use including most ATT apps and facebook. I also don't use auto-brightness. Many of these settings affect battery life, and I can imagine (only) simultaneous combinations heating things up. Best heat and battery management to all.

    Sounds to me that the engineers of the phone didn't get it correct. A computer has exhaust fans to
    try to cool the computer, the phone needs a way to do the same, but the engineers of the phone left it
    out. Most of the time my phone is in my pocket, but it could be bad to put a hot phone in the pocket.
