    How is the battery life ? I have installed 10572 build via rolling back to 8.1 and upgrading it. Battery life on my 1520 is horrible. I get maximum of 6-7 hours ..Any suggestions to improve battery life?
    Check which apps can run in the background and disable them. I've disabled all of them for now

    OK, this is by far the most unstable build I ever had on my 1520. Never experienced so many reboots and app crashes! But this happens if you do some dramatic optimizations for the first time, I guess.

    almost zero restarts for me on 930, which is basicly the same phone as 1520, so there might be an isolated issue with yours?

    Pew!! ... The worst version yet on my 930 daily driver ...
    Battery is draining - apparently by the messages app (70+ pct)
    One drive is buggy - or at least less intuitive to me
    Camera crashes
    I think in general more flaws in most aspects of my usage. With all previous builds I was only looking forward ... now I am not sure

    Vodda is correct. However, it's not working and/or enabled in this build.

    Same hardware does not necessarily mean same software... Btw. I do not have many apps installed, even removed some that come with the image like Facebook and most of the Lumia apps.

    I'm on Windows Insider since it was started, tried all Windows 10 Mobile Preview builds and always reverted back to Windows Phone 8.1 for one reason or another, this is a first build that I'm using as daily driver on Lumia 535, no issue except two or three restarts. Just need 3G only setting for data back :-)

    930 here. Previous builds were horrible when it relates to battery lifetime. This build is great and 1 charge lasts more than a day with average usage.

    After a hard time to install it (two roll back to 8.1, then two hard reset to have everything working), it's by far the best w10 expérience I had on my L1520. Not a single bug, lag, resume screen, haunted tactile (I'm not talking about the fantom touch, but the time when the screen just went crazy) for three day (of my personnal use). But a store that open quickly, same for app installation. Well, an overall really fast and responsive expérience.
    I was wondering about the L950XL, but now I'm just amazed again by how my 1520 run beautiffuly :D

    Just try 10572 on my Lumia 535 Dual SIM. Basically it is much better than previous builds and looks like I can use it for daily driver but still need to test it at least 2 or 3 days ahead. Some glitches that I found:
    - Fhotoroom and 6tag don't work. Stuck on opening screen. Already tried to uninstall and reinstall those apps. My setting for installation location is on the device, not SD-Card.
    - Can't see sub-folders inbox in Exchange email. Already tried to remove the account and add again, no luck.
    - Camera is flickering on right side (or top side when in landscape mode). I am updating the Windows Camera when I write this post, so let's see if the update fixes this.

    Any suggestions on those?
    Thank you.
    Update: after updates Outlook email, now I can see all folders in my Exchange email.
    6Tag and Fhotoroom are still not working, Windows Camera still flickering on right side. Hard reset didn't help.
    Set network to manual and also set APN to manual to fix problem with network connection.
    Still okay for daily driver, anyway.

    So, I *just* got my M8 yesterday and not knowing what I could and couldn't do, I told Cortana "Play me music" and she cranked out a random piece out of my songs. After turning the volume WAY down, I tried "Play me Kansas" and she did. Maybe give a shot at "Play me the beach boys"?

    Edit: Except, I just tried saying "Play Kansas" without the Me which she did with a flourishing introduction.
    Mmm still not working for specific artists on mine even if I say "Play me", did work for "Play me music" though, I do have my music stored on my SD card, wonder if that might be why?

    Build 10572 impressions on Lumia 920:

    *Firstly, it's the most stable build ever. You can use this build on your daily usage.
    *No heating issue (if you keep your background internet and location usage under control. Suggestion: Turn off the location info for apps except Maps if you have heating issue)
    *Still there is slight lag on Lockscreen and some system apps like People/Contact List, Messages and Store.
    *Call/Phone and Storage apps are really faster and bettter than previous.
    *Mobile hotspot has still the same issue. It still disconnects when the screen gone dark.Have to set lockscreen time unlimited.
    *Battery performance is better, too.
    *Refreshing time in Photos app is slightly better but still not fast enough.
    *But still some missing points which will probably be completed in future builds.

    This and the previous (10549) build actually has my phone battery draining more than usual.
    I especially notice this when I'm using the phone.

    When on standby, the usage is about 1% per hour but when I start to use, it goes from about 4% per hour to higher. I've switched off all background apps but still usage is higher than normal. It has to do with the way the phone works with cellular connections

    I'll wait it out and put 10575 and hope for battery usage similar to 10512 if not better

    On a side note, I was able to take 300 photos+videos, check Here maps for a few minutes and take a couple of screen shots while my battery drained from 100% to 15% over the course of 8 hours on a trip. Flight mode was on. That's the most it ever did I think. This was on build 10549, using Lumia 1020 and Lumia camera

    On Lumia 1020

    1. Battery life: Definitively improved compared with previous builds. No heating issue. Comparable to Win 8.1 mobile

    2. Camera app: Even worse from previous builds. Frequent crashes and freezing. I had to reboot my phone several times because of freezing after taking one or two photos. Reviewing photos is also very annoying. Unusable in terms of taking photos and reviewing. Fortunately, the app 'lumia photo' works smooth, therefore I don't use the default camera app any more. I cannot believe that the developers in MS do not recognize this issue.

    3. Edge: In terms of speed, It is probably faster than IE in Win 8.1 mobile. However, the browser is unstable and sometimes unresponsive. Changing the default search engine bing to google was also very tricky. I had to change the system default language to English from the language in my country to change the default search engine. Automatic syncing the browser's favorites to the favorites in IE works very well.

    4. Store app: Scrolling is almost impossible in 'Download and update'. Frequent crashing as well.

    5. Lock screen delay: Major updates released yesterday resolved the lock screen delay.

    6. Message app: Buggy. My wife and daughter have similar telephone number that the last 6-digits are the same. When my wife send a text message to me, my phone indicates the message is sent by my daughter. The other issue is that texts are not fully restored after installing this new build.

    7. OneNote: Numerous crash.

    Overall impression: Even though the loading and resume issue is gone, the core apps such as Camera, Photo, Message, and OneNote are now full of bugs. I hope these issues are resolved in the upcoming build.

    Overall build is ok and the OS is responsive Lumia 830

    Battery: life of battery is about 75% of what I had
    Battery App: does not display apps used in the past so I can't tweak the settings
    Scrolling: very jittery especially in FB,USA today and the MS news app
    Camera: flakey, takes too long to save a HDR picture
    Photos: too long to load and when sharing through an app it sometimes does not work
    Outlook: need different alerts for different email (has this in iOS)

    Like the look and feel, but still needs to be refined, probably of for daily driver at this point but some things will irritating.

    Raghu, I think the best way is to do it like this, works fine with my 1520, every time:
    - Document apps and settings (Screenshots e.g.)
    - Flash 8.1
    - during 8.1 setup, put in ms creds but do not backup or auto update any apps
    - install insider app, upodate to new W10M build
    - hard reset
    - start over fresh, do not use a restore (!)
    About power usage, what does the battery saver usage tell you in settings? Who / what is using the battery up?

    Agreed, this is how I usually install the previews. There are definitely less problems then. However, this build is only usable for absolute enthusiasts or people coming from the robot.

    I have to echo the sentiments of others in saying it's by far the best build and really brings to fruition what Windows 10 mobile is trying to achieve. MSFT knows this will result in a continuation of bad reviews from short sited individuals, but I expect big things next year.

    Im seriously considering installing this on my 520 but I am concerned with my games and apps. Can I backup them? Will it erase the progress I had with my games?

    Sorry it's my first time to do this. Sorry also for my English
    I assume you are starting with 8.1? The update on my 520 took about 3 hours to get it stable. 8.1->8.1 Denim -> WM10.
    If you are not ready to loss data, you should probably not update. Many people were having problems with text messages not being restored, me included.
    You may have to do a hard reset to get your phone stable and you may not get all your data back.
    This is test code. It is running better then the last code, but it is still test code.
    I have been rebooting my phone about every 12 hours because it starts to get slow and unstable.
    I'm still seeing resuming and loading screens. I'm using this build as my daily driver.
    Good Luck.
