Hi.
Since coming from android I've been a frequent user of apps who lets the phone change it's settings due to specific triggers, like turning silent at night and loud in the morning, turning silent when a certain calendar happening occurs, turning of wifi when leaving home etc.
Is there anything like this for using along with windows phone?
Thanks in advance

Actually, (some of) this is theoretically possible, but nobody has done it so far. It's also not going to be allowed on the Marketplace; you'd need to use some unofficial APIs.
For example, the DllImport Project already has shown the ability to control the phone's volume. Programmatically muting the phone at a certain time, for example one minute after a meeting is supposed to start, should be pretty easy.
The trick would be to make sure the phone also un-mutes it when the meeting ends. WP7 doesn't (officially) allow third-party software to run continuously in the background, and while you can schedule a time for the software to run, it make no guarantee ot to-the-minute accuracy. There are ways around the official restrictions, but most of them have serious battery-life considerations (although telling the process to sleep for the next 30 minutes * 60 seconds * 1000 miliseconds would probably work without draining battery). Additionally, I'm not sure how much access apps officially have to calendar data, although on interop-unlocked or full-unlocked phones there are varius ways to access that data.
For things other than volume control, like enabling or disabling WiFi (almost completely unneccessary on WP7, the WiFi power management is, if anything, too conservative already) you'd need to find the place in the OS that controls it. Probably just sending SetDevicePower to the Wifi driver would work to disable it, though I don't know if that would show up correctly in the UI.
Hi all
I've tried 2 Surface RT's now, and both have horrendous battery problems. I've tried refreshing them, resetting them, installing all updates, turning off Bluetooth and many of the live tiles, but still the battery lasts at most 24 hours. There's nothing much installed, just a few apps (ebay, Flixster, a book reader), I have two email accounts (Hotmail and an exchange account), and that's about the lot. All updates have been performed, but still, on two separate units, the battery life is so bad that I'm thinking I can't use this as my daily tablet.
I've done the powercfg -energy test, and I get 2 errors - one is that the Nvidia Wave Device driver is preventing the system from sleeping, and the other being for high utilisation (between 18%-30%). If I turn the volume off, the Nvidia driver warning disappears, but the battery life is still poor and I don't know why the volume would need to be off when not in use. I can't find any other apps that rely on this driver (it's a speaker driver as far as I can tell), so I'm well and truly stumped.
Does anyone have any ideas on how to fix this Nvidia driver problem?
Thanks
Do you use any music apps or web pages on the tablet? If music is playing, or even paused, the app may prevent sleep. However, generally speaking, such apps should be suspended when idle for any meaningful period of time.
Even with some third-party Win32 programs running in the background on my Surface RT ("jailbroken" and then installing things like MirandaIM, which don't get suspended automatically) the tablet lasts at least three days if fully charged when I put it to sleep (I don't usually try to push the battery life, so I'm not sure what the max is) and without background network-connected processes it lasts for over a week.
Hi
Thanks for taking the time to reply. No music apps are or have been running. Since wiping it all and starting from scratch just last Thursday I've only used it for emails, web browsing and reading books on a book reader. Just can't understand why I've had such bad battery results with two separate units!
My guess would be along the lines of what GoodDayToDie said, some app you use is probably holding a wakelock on the device.
Can you list out the non-MS apps you're using to see if we might be able to find out if it is one or not?
Morning
The only apps I've installed from the store are ebay, Flixster, Book Bazaar Reader and Facebook.
Maybe I'll try to uninstall these, running the powercfg -energy report after every uninstallation. I'll report back!

Right, all apps listed above removed, ran the powercfg -energy report and still getting the Nvidia driver error, and processor utilisation at over 20%. No apps were running in background, and same results even when volume was off.
Am completely at a loss now!
Have you run Windows Update? Normally it's not even optional (you can disable it if you use the registry, but that's the only way) but the only thing that comes to mind is that your tablet may be missing some required driver update or something... that's very odd though; I haven't heard of any such problem from anybody else.
Given that the nominal runtime of Surface RT when not in sleep mode is 8-12 hours, you're definitely not going to have a good experience if sleep mode isn't working. Technically you *can* shut down the tablet between uses - it boots up very quickly, at least - but that's a pain compared to sleep mode.

Hi
Yes, I have run all updates, including the firmware update dated early April. I have looked for updates in both the normal 'tablet' mode and also by going into the update section of the desktop. So everything is uptodate, all of my apps from the app store have been uninstalled, but still the Nvidia driver error reports that it won't enter sleep mode and processor utilisation remains high.
As stated in my first post, I currently have two of these tablets to play with, and I have exactly the same issue on both, so I think we can rule out hardware problems, leaving some sort of software glitch. I did see this Nvidia problem on another forum, but the guy who posted it later reported that it simply went away, so that doesn't ger me anywhere.
It seems like a great piece of kit, but it'll be going if I can't resolve the battery issue.
Hi
Although I don't have any battery drainage I have to confirm that I have the same 2 errors despite the fact that I have all the updates. Can anyone else confirm if they have these errors?
That's odd. If you have the same errors but not the same battery drainage, I wonder what is causing my battery drainage and how I could check this out?
It does definitely seem to be linked to my driver error. The same problem has returned - the Nvidia driver error reporting its preventing sleep mode when the volume is on. When volume is off, that error disappears and battery life seems a little better.
Have played around with it some more, but same issue still present on both of the Surface RT's I have - battery drain unbearable. I have to ensure volume is off whenever closing the lid/pressing power button to put it into sleep mode just to try and see sleep mode actually kicking in.
If I had installed lots of third party apps I could understand some battery loss, but given they have both had full wipes, all updates installed and haven't got any apps installed other than pre-loaded ones, I just don't understand how I have the same issue on both machines. Only other thing to try would be removing my email accounts, but then there would be no point at all in keeping it!
Does anyone have any suggestions at all? If not, I think it will be time to see them going.
My only thought is incredibly bad luck and both devices have the same hardware fault.
My surface sips battery. Have never had any issues with battery

That must be nice, both of mine use so much juice they render themselves useless!
I can't think it's a hardware issue on both, especially as the huge loss of power seems linked to when the volume is on 2 or above and sleep mode is for some reason prevented.
Anyway it seems there may be no solution to whatever software glitch I have, and all of this has very much made me look at the Surface with a huge amount of disgust, so I think I'll go back to my Galaxy Note which just doesn't have such ridiculous issues as these units.
Well no-one else seems to be experiencing these issues so whatever is wrong is something with your devices. I would contact the vendor.

The same hardware fault on two devices when the error report is linked to Nvidia wave device driver error preventing the units from going into sleep mode? Doesn't seem all that likely to me. I still think it's a software error, as this was reported also by somebody on a different forum, but with no clear resolution.
Thanks anyway.
Apart from the error, good practice for saving battery life can also be setting the screen brightness to low. In your Nvidia settings do you have the option to enable and disable power saving?

One could argue that the software error is environmental, as it only seems to be a minority experiencing this issue. There could be a hardware fault though, don't discount just because it is two devices, you could have been incredibly unlucky and received two devices that just happen to have the exact same fault.
Well I've done some more playing about with the device, and it seems my battery drain issue seems linked with my work email account. If I am just running my normal Hotmail account, battery drain seems fine. When I add my work Exchange email/diary account, the battery drains like nothing on earth. Not sure if this has anything to do with the fact that to even get this work email account working, I had to get our IT chap to send me the security certificate for me to install.
Not sure if anyone might be able to suggest a way of having push emails still running on my work email account without the battery draining hugely?
Hi guys
I know this issue has been mention a bit, and I've searched through countless threads but I find the search system on the site a little counter intuitive, like forum searches will only bring up the thread, not the actual key word references and I have to search again within the threads to yield results, but I'd like to clarify a few things.
I'm running Cm11 nightlies on the phantom kernel and I have the screen wake issue. It takes multiple attempts to wake up the screen. OK.
I understand this is a problem with Kitkat roms for our device. However, my case is that there is a 50-50 chance that the screen doesn't wake up at all and I have to pull the battery. This makes any rom almost unusable for me as 1 out of 2 times I have to pull the battery to access the phone, Music continues to play, and I can skip tracks or play or pause, and even take photos, which means that the phone unlocks only the screen doesn't light up. If I hold down the power button, I can feel the phone vibrate to indicate the shutdown menu and sometimes I can blindly reboot or turn off the phone by tapping the screen roughly where the menus would be, so the touch is working.
Roms have been reinstalled and dalvik wiped etc but no improvement
I'd like to know if there's something I've done wrong to have so much poor luck. I don;t mind waiting for the screen to light up, or even a few tries, I'm aware of the unstable nature of nightly roms, and I am happy to use it and contribute usage stats to help further development, but not being able to get the phone on is a massive problem, especially when receiving a call
If anyone has any tips, I;d love them to let me know so I can add here as a one stop thread to general KK problems and work-arounds.
Pr m,aybe it's just my phone
Current mods
Xposed framework modules
greenify
kk bugs fixer (currently disable as seems to make no change)
minminguard
no lock home
Xposed gel settings.
No crazy overclocks or aggressive governers (tested with ondemand, intelliactive no difference, but great battery)
General rom experience apart from this - Excellent battery and very snappy, only a little skipping with audio (even with cache increased to 4010)
Cheers people!
try another kk rom
i did not use cm11 b,coz i had problems with the low reciever volume
tryout carbon rom or vanir aosp
they are too good
SOLVED
OK, thanks for the suggestions, actually I had the same issue on all roms that I tried.
The fix was the following, I disabled the NO LOCK HOME Xposed module and now all is back to normal.
i think there was an issue with it auto unlocking the screen on wifi or cel tower that caused the lockscreen to crash from time to time or get stuck. All is working like a dream now.
It~s a shame really, here in Brazilo with the rise of the Iphone and the high robbery rate, it´s quite common now for thieves to stick their gun in your face and demand your password or for you to unlock;disable the password during the robbery so that they can reset the apple acount or phone for resale. With nolock home I could save the cel towers near my home and work (for my walks to and from the subway) so that in case of a robbery, the phone just opens up and shows its unlocked, and then I can remotely wipe it later without giving up account details. Anyway, anybody else with this problem, thats the source of the Issue
This problem shows up periodically when I leave my S7 stationary on a desk or table while in discharge mode. I found an xda thread describing the exact symptoms, but for the S6. My phone is an S7, of course. That S6 thread is here: http://forum.xda-developers.com/galaxy-s6-edge/help/push-notifications-stop-screen-off-t3071248
I have my device set so notifications will appear on the lock screen. And under Settings > Notifications I have about 5 apps set for priority mode. That works consistently to bring notifications from those apps to the top of the notification list. The problem is that occasionally when the screen turns off --not consistently-- all push notifications are suppressed until I turn on the screen again. At this point, all of the suppressed, pending notifications fire off their associated alert sounds and each of their alert banners pop onto the lock screen. I can never know when the notifications are going to be suppressed like this when I toggle off the screen or when it times out on its own.
Am I the only one who experiences this issue on the S7? I had possession of some other S7's some months back and at least two of them demonstrated similar intermittent push notification behavior. However, I had no idea exactly what was happening at the time (i.e, whether it was the individual apps malfunctioning or perhaps a lagging issue with the servers/networks they were using). But from my experience to date, it appears that the absence of notifications on those devices during screen off mode may have been the same issue.
There was a great deal of concern about this within the S6 thread I've cited above. But no definite solutions were given; the general hope was that a future update would correct the problem on the S6 and that the S7 with android 6 marshmallow would hopefully not include the intermittent notification problem. If I've missed an informative thread on this issue relevant to the S7 (or the S7 edge) please direct me accordingly.
Thanks
Used to happen with my S5, afaik it's Marshmallows new low power mode, 'Dose' that causes it as it didn't happen with Lollipop

In that case, how is the best way to disable this mode? Package Disabler perhaps? And why am I the only one who seems to have posted about this matter as far as the S7? Timely notifications are pretty important... so I would think that if this were a typical power saving side effect on the S7 that many S7 owners would be speaking out about the notification lapses. It's fairly puzzling.
Thanks
Dose being the cause is just my take on it, I couldn't think of anything else it could be with my S5 either, and as I said it never happened with Lollipop, and Dose only arrived with Marshmallow, so I put two and two together
Not sure you can disable Dose, other than have something running in the background causing a wakelock, which would drain your battery
Might be something else causing it, but I couldn't see any other explanation
Something I did notice though was if the phone was on 4G Data instead of WiFi, notifications were instant, but I was only on 4G while I was out, and when the phone is moving, dose doesn't work, it has to be completely stationary

Hmm... in my case it is happening exclusively on 4G without wifi running. So maybe it's something else. Most of the time notifications come though immediately. I'd say that during only about 10 or 20% of the phone's stationary time they are repressed until screen on.
Have a solution!
Faced the same issue, you have to exclude the apps you need notification at 2 places in the settings.
For the doze settings, go to settings, battery, battery usage, more ( top right), optimize battery usage , select all apps and select the apps you need to show notifications.
Second place, settings, battery, go down to app power saving, click details, set app you wish notifications to disabled.
It happens intermittently and has happened for the almost 2 years since I bought it. It has been a minor annoyance which gets annoying in certain scenarios. I have waited for a update to hopefully fix it and have tried removing or changing setting of suspected culprits. However to no success. My device has had a factory reset 3 times and this still happened during a fresh install. No third party apps should be accountable.
During regular use:
1. Screen will turn off and the device will lock
2. After about 2 seconds I will be able to turn the screen on which will display the lock screen.
3. The lock screen will be blank with my wallpaper, the lock screen widgets (time, date, text, shortcuts.) Will eventually load in within 5 seconds, this could be instant or delayed up to 5 seconds.
4. I will finally be able to unlock the device where I'll be greeted with an empty home screen. The launcher however will restart. All of the UI elements will slowly load back, including the notification bar.
5. After about 5-10 seconds. My device will become functional and up to speed as usual. Apps may have lost their memory/recent data. (Eg: YouTube restarts to home menu, chrome page will have to reload.)
To me it sounds like a memory overload. Perhaps an app is causing a memory leak? RAM is faulty or succumbing to SEU's due to poor quality materials. Battery or power regulator fault causing voltage surge or sag resulting in MIUI crashing.
I'm really not sure
I have been looking for the issue online every now and then. However I cannot find anything.
Anyone else had this issue? Anyone know better than me and have an idea?
I very much like this device and this is the only issue I'm having so far.
