    After updating to CU I started to note that after using for example Edge for some time, the performance is degraded, especially scrolling performance. The same happens in other apps. If I leave the phone for say half an hour and then pick it up, the performance is good, however after maybe 10 minutes the performance is again degraded. This makes me believe that something is wrong in regard to thermal/power throttling in the CU. Am I the only one with this issue?

    I haven't noticed anything like that.

    Only issue so far is that Store and map downloads are slow like molasses, even on 100 Mbit WLAN.

    I find battery drain high when in use, super low battery drain when not in use. I'm using a 950XL and don't find it lagging during usage

    I have noticed the same thing. This has been the least stable build I've ever had on any version of WP, with things like lockups, reboots, excessive heat and battery drain. I'm on a 950XL.

    For me it was all good and well, it was really fluid in the beginning, though today Messenger started lagging pretty bad and somehow I forgot what I was doing in the morning but however my phone was stuck and had to make a soft reset. Somewhy it drained my battery for 10%. Otherwise I didn't notice anything differences regarding battery life, it wasn't really too well even on release builds.

    Today I noticed that controls for music that I usually use on my Bluetooth headphones don't work properly and it's not the headphones because they power up normally (same button is also used for skipping songs).
    NOTE: I am on insider fast though but not many things changed there anyways

    On my 950xl I've noticed problems, especially since the CU update:

    Extremely high battery drain when in use
    Phone freezing and/or rebooting, usually happens when receiving or making a call
    Phone heats up really bad when playing games now
    Maps and navigation require screen to be on to work. If screen goes off then you get the "Tap to resume navigation" message. This is absolutely unacceptable and if not fixed soon I guess its time to get an Android. I use my phone for nav and rely on the bluetooth spoken nav. Keeping the screen on causes rapid battery drain.
    Randon SD card failures saying its not there anymore requiring a battery pull and restart to get the SD card recognized again.

    My 950 is running really well on CU. I would suggest backing up and then doing a factory reset. Then try Edge and other system apps for a day or so, with no restoration of settings or apps and see if it's better. Then reset again and then restore everything from backup, see if it's worse. You might conclude that you just need to start from fresh.

    A factory reset resolved my performance issues. It feels a lot better overall and no performance degradation after heavy use.

    Everything is ok with mine except the camera focus issue I have mentioned in a few other posts. Once that is fixed I will be happy with the performance again, but as it is I just don't even try to use my camera, make my wife use her iphone (gasp) or pull out my Pixel (double gasp) if I have it with me.

    Scrolling performance in Edge is bad yet again. Possibly happened after a massive language localization update through windows update, never had that type of update before.

    I got that one as well, but I assumed that was the .297 update?

    I don't know. Really bad scrolling performance now and constant lockups. Phone not even warm. Will have to jump ship to Android really soon after L920, L930 and L950. Really bad of Microsoft.

    That's really bad, sounds like we have very different experiences from .297. Scrolling in edge on my phone is like doing it on any other phone.

    Sometimes the phone backup is the culprit. You can try to do a hard reset without restoring from a backup.

    1 - Back up using Contacts + Messages app, it makes a backup of your SMS/MMS/Contacts on your phone. This works even if you don't have a memory card, look at the bottom of the screen.

    2 - Copy the folder to a computer, together with any files you want to keep..

    3 - Perform a hard reset, and don't restore from any online backup.
    *** Optional, instead of a hard reset (if you don't think it's enough), you can use the WDRT to reinstall Windows.

    4 - Copy the backup folder back to your phone, use the app in #1 to restore.

    After that you have to download your apps manually, but Store usually keeps track of which apps that are associated with your account.

    As a last resort you might consider to use your warranty if you still have one. Mine is 2 years, although it's not the same everywhere.

    Got the same issues on my 950xl I have never had my phone scroll like that doesn't do it all the time just randomly and it locks up from time to time also ever since CU. I am trying to avoid a 5th hard reset and no back up. I have to admit it does fix my issues but damn this is just getting unacceptable to me I'm tired of resetting my phone after updates.
    the big issue with having to reset your phone now days is you never know if a app you have been using is still available until you go to find it in the store and its gone. This has happened to me a couple of times.

    The factory reset with backup after CU update fixed it but then the .297 update broke the performance yet again. Scrolling performance on this page right now is so slow it would take me a minute to get to the top... Just not acceptable that one would have to factory reset after every update. Even with backup the whole process takes 2 hours to get everything back to how it was.

    I also had bad scrolling performance in edge just after updating to CU on production build on my 950 xl. Read somewhere that maps displays better by lowering screen display from the recommended 350% so I set it to 300%. Text got so small on that setting so I changed textscaling to 150%. I find everything displays better after that and I dont have any issues with scrolling in edge actually seems faster then before CU. Lowering screen display below 300% caused calender display issues. I did not factory reset after CU but will do that when I have time since this is a bigger update.

    If you cant find previously installed apps in store after a reset they can usually be found and reinstalled from my library in Store menu

    Call history is messed up.

    1. search for a hotel in cortana
    2. click on the call button
    3. as if you are not in a hurry it asks you which app you want to use people or skype (I want a face to face with the ***** that designed this behaviour)
    4. choose people app and make a phone call
    5. go to your call history, and voila it is not there
    6. your phone can not even keep track of the calls you make
    7. you have to search the hotel name and do the steps 1-5 to redial!!
    8. this is simply unbelievably terrible engineering, simply unbelievable

    especially if you are driving you want to access the last called list through your car's system, which accesses your phone's system. but the number is not there. this is a normal use case for a smart phone.
