I have screentime set up for managing apps and usage and am having a hard time making sense of the numbers. In this instance I have set all apps to be limited to 2 hours, and you can see that the time used is around that amount (I changed the limit to 30 minutes just before this screenshot because I was experimenting). However, the used time is nearly 5 hours. Why does my screentime report 4:42 and usage continues without hindrance. Changing it down to 30 minutes hinders usage but to allow later usage, I have to allow &gt; 4:42. This is inconsistent with the app usage and makes management difficult. What’s being counted and why does it vary so wildly?

Under , the report for the time spent on my phone is 1 hour 5 minutes. However, when looking at all the apps used, the time spent on the phone adds up to about 28 minutes and not 1 hour 5 minutes. Time spent on iPhone for the full day:  But looking at all apps, the time spent is about 28 minutes    How is Screen Time calculated?  Why is time spent on the iPhone calculated to  1 hour 5 minutes if time spent on all apps is really about 28 minutes?    Note:  I'm using ios v14. iPhone SE 1st Generation. The iPhone is supervised, (but I don't see why that would matter). Share Across Devices is enabled, however, I don't own or use any other apple devices besides this iPhone (seemingly this shouldn't either matter).

I can't find a way to set a daily limit to my daughter regardless of her devices. I want her to spend 2h max on screen no matter which device she uses on that day.  Yet she's getting 2h on her tablet and 2h on her smartphone.  Am I missing something? Does Family Link only allow to set device-specific limits?

A few months ago I was introduced to the new  type and was glad 's flaws with regard to time zones were finally taken care of.  However, I was left wondering if there were any overhead or problems that could occur from using this new type.  I work on a multi-locale web application. Does anyone know of anything that could sway me from just using it for all my date/time work? Is there a window for abuse here?  Reference:

I'm pretty depressed that I'm finally one of the people posting this, since I'm usually telling those people "you're obviously wrong", but either I don't understand how consecutive day counting works or this seems impossible:    The last activity count is right; I was on SO at about 18:30Z yesterday (Saturday). Is it possible for the consecutive count to be at 1 if my last activity was yesterday? It would seem like it has to be at least 2 then (although I was definitely active Friday; I suspect Saturday is the "missing" day since all I did was poke through the newest question list and check the current flags)

There is an application usage time tracker script, that Jacob Vlijm wrote in another question.   Due to small reputation I cannot comment there. So I will ask here, is it possible to sort entries by percentage of use, instead of current relative order?  Here is a script in case you don't want to check the original question.  #!/usr/bin/env python3 import subprocess import time import os  # -- set update/round time (seconds) period = 5 # --  # don change anything below home = os.environ["HOME"] logdir = home+"/.usagelogs"  def currtime(tformat=None):     return time.strftime("%Y_%m_%d_%H_%M_%S") if tformat == "file"\            else time.strftime("%Y-%m-%d %H:%M:%S")  try:     os.mkdir(logdir) except FileExistsError:     pass  # path to your logfile log = logdir+"/"+currtime("file")+".txt"; startt = currtime()  def get(command):     try:         return subprocess.check_output(command).decode("utf-8").strip()     except subprocess.CalledProcessError:         pass  def time_format(s):     # convert time format from seconds to h:m:s     m, s = divmod(s, 60); h, m = divmod(m, 60)     return "%d:%02d:%02d" % (h, m, s)  def summarize():     with open(log, "wt" ) as report:         totaltime = sum([it[2] for it in winlist])         report.write("")         for app in applist:             wins = [r for r in winlist if r[0] == app]             apptime = sum([it[2] for it in winlist if it[0] == app])             appperc = round(100*apptime/totaltime)             report.write(("-"*60)+"\n"+app+"\n"+time_format(apptime)+\                          " ("+str(appperc)+"%)\n"+("-"*60)+"\n")             for w in wins:                 wperc = str(round(100*w[2]/totaltime))                 report.write("   "+time_format(w[2])+" ("+\                              wperc+"%)"+(6-len(wperc))*" "+w[1]+"\n")         report.write("\n"+"="*60+"\nstarted: "+startt+"\t"+\                      "updated: "+currtime()+"\n"+"="*60)  t = 0; applist = []; winlist = [] while True:     time.sleep(period)     frpid = get(["xdotool", "getactivewindow", "getwindowpid"])     frname = get(["xdotool", "getactivewindow", "getwindowname"])     app = get(["ps", "-p", frpid, "-o", "comm="]) if frpid != None else "Unknown"     # fix a few names     if "gnome-terminal" in app:         app = "gnome-terminal"     elif app == "soffice.bin":         app = "libreoffice"     # add app to list     if not app in applist:         applist.append(app)     checklist = [item[1] for item in winlist]     if not frname in checklist:         winlist.append([app, frname, 1*period])     else:         winlist[checklist.index(frname)][             2] = winlist[checklist.index(frname)][2]+1*period     if t == 60/period:         summarize()         t = 0     else:         t += 1

So, I've been giving the mobile application a while for the last week or so, and I'm thrilled to be able to give feedback and report bugs on it.  I'm also thrilled that I can use the Stack Exchange network on my mobile, or tablet!  After about a week, though, I started to realize a few deficiencies in the application - some of which I've already reported as bugs, some of which are already reported, and some of which I'm not sure I should report, since I don't know what role this application is meant to serve.  So, I consider myself a bit of a power user of [Meta]StackOverflow.  I ask questions (at least on Meta), write answers, comment, but the bulk of my time spent on SO isn't geared towards that - it is, more times than not, flagging content, reviewing content, editing content, and otherwise consuming content.  The mobile application is certainly geared towards producing content and consuming content.  It does a fine job of that (although there are some rough cuts).  What I find myself doing, more often than not, though, isn't directly related to production or consumption of content - although I would agree that editing posts while on a 4 inch screen isn't ideal.  I'll compare my flow with the mobile version of the site.   On the mobile site, I can check my profile.   I can see my cumulative daily reputation score here. I can see my favorite questions here. I can see my most recent activity. I get credit for visiting the site.       In the app, I can check the feed.   I see new questions on sites that I'm definitely a member of, or that I've recently visited in the app. I'm not convinced I get credit for visiting the site on the mobile app.  Nor am I convinced that I should - although I want to.       On the mobile site, I can see what badges I've earned overall.   In the app, I can see what badges I've earned that day.       On the mobile site, I can order the results of questions with a lot of answers by votes.   On the app, that's not possible.    What I'm getting at is, despite it being an early alpha, it doesn't feel like it's going to have feature parity with the mobile desktop site.  So, is it meant to supersede the mobile desktop site?  Is it meant to be a CRUD application for SO?  Or does it fit somewhere in between?  I can provide better feedback and bug reports to the team if I have a clear understanding of what niche the app is trying to fill.

Whenever I lock my screen (using command+control+Q), the display goes to sleep within about 5 seconds. How can I prevent this?  This happens while plugged in, and my screen is set to never go to sleep while on power:    Even if I wasn't plugged in, on battery life, the screen should go to sleep within 2 minutes, not 5 seconds:    I'm on High Sierra 10.13.2.  edit: I gave up on locking with cmd+ctrl+q and just went with enabling my screen saver and setting the system to require a password on screen saver wake.

Accuracy Vs. Precision  What I would like to know is whether I should use System.currentTimeMillis() or System.nanoTime() when updating my object's positions in my game?  Their change in movement is directly proportional to the elapsed time since the last call and I want to be as precise as possible.  I've read that there are some serious time-resolution issues between different operating systems (namely that Mac / Linux have an almost 1 ms resolution while Windows has a  50ms resolution??).  I'm primarly running my apps on windows and 50ms resolution seems pretty inaccurate.  Are there better options than the two I listed?  Any suggestions / comments?

I've got a Google Spreadsheet that looks roughly like this:   Date        | Start time  | End time    | Minutes  ------------+-------------+-------------+-----------  1/11/2012   | 11:39       | 12:41       | ?!  ------------+-------------+-------------+-----------              |             |             |    Right now if I fill in the number of minutes between the two times of day by hand. Is there a straight-forward way to calculate a time delta and have the spreadsheet do it for me?

I have been feeling this way for a while, looking at task manager mentally ballparking how much physical memory should be in use, and noticing a large disparity. I finally got around to measuring it. Taking the results of tasklist and adding, gave about 3.87 GB. Task manager told me I was using 4.6 GB of memory. This seems like a large disparity. Where did it go?  EDIT: So its clear, it is not going to prefetch. It has also been suggested that its part of the OS, but not part of any of the system processes. If this is true, please find a way to get the OS to tell me how much memory is getting used. Since I want to find out where the memory went, asking me to look at the difference does nothing for me.  EDIT 2: It is not the following:   The kernel The cache Hardware reserved memory   Picture of resources taken up. Not quite sure what it will do but...

My father has a Samsung Galaxy S2 with the stock GB and un-rooted. The phone has been working flawlessly, but lately (since about 2-3 days) it began to use a crazy amount of data.  He normally uses about 300 MB per month, but now the phone is using about 20-30 MB per hour during phone standby!.  Also he notices is that the battery is lasting about half of the previous time, which is evident in case of a long running process.  He didn't install/update anything lately and all the settings are set for minimal data use. (Like no Sync..etc). He also has all the known data-hog apps kept disabled.   He has installed an app call “” and the app says that all the data is being used by OS services but there is no detailed information.  Just for clarification, he doesn’t have too much applications installed. Just: Whatsapp,  Viber, Facebook and Twitter. But as I said before, he has all the auto sync off, and all these apps where installed months ago.  My question is: Is there a program that can help us to find out what is going on? Something like a “on the fly” (real-time) data analysis?  Any other ideas on what could be happening here?  Thanks! Edgar

It's all int the title; I find myself unable to set a precise time interval defining how often the background pictures of the theme I am currently using change.  The only similar option available in Windows 10 settings applies only to single background images and not to multiple background images included in a theme.  Thanks in advance,  N.

Fig.1: A typical prompt, asking user for feedback/rating in iOS Background Any serious smartphone users must have seen a message similar to Fig.1 above at least once. Variations of such prompt include: &quot;Please give us 5 star ratings if you love this app!&quot;, &quot;Rate us :)&quot;, &quot;Your rating helps improve this app!&quot;, etc. Basically, Fig.1 asks user to leave a (nice) feedback/rating for the app on its AppStore(or equivalents).  The Shorter Question  When and how often should a mobile app user be asked to leave a feedback/ratings?   The Longer Question #1. Which User-statistics? What are the significant user's behavioral statistics that should be based on to generate Fig.1? For example:  Number of runs since install/reinstall of the application Time elapsed since current application run Time elapsed since first application run Time elapsed since first application install Certain events (e.g. after certain number of stages are cleared for a game app)  #2. When to Ask? If multiple user-statistics are chosen to be calculated to generate Fig.1, specifically how should the user-statistics satisfy the condition of the event? For example:  Form a unified equation (e.g. X^2+Y^2=Z^2) with all significant user-statistics partaken fairly to trigger the event. Create (multiple of) &quot;absolute&quot; event triggers (e.g. every 10th app run; elapsing 2 hours since current application run). Both of the two. Generate Fig.1 whichever comes true first. Neither of the two. &quot;There's a better way!&quot;  #3. How often? What would be the optimal min/max frequency of Fig.1 generation? By optimal, I mean users are not to be bothered too much, yet developers gain maximum output of great feedbacks from users? #4. &quot;Don't bother me again :(&quot; Should users have an option to opt-out from receiving Fig.1 at all? #5. Universal User-statistics for All Mobile Apps? Should apps under different categories be based on different user-statistics? There are significant differences in size and type of user-statistics in apps under different categories. For example, a &quot;Flashlight&quot; app is not typically run for one hour straight, while a music/movie streaming app may be run for over one hour. #6. &quot;This app does not need more feedback.&quot; Should every app of all kinds of user base ask this message? If any, should any mobile app stop generating Fig.1 when target conditions are met (e.g. downloads count, active user count, feedback count)? #7. Feedback/Rating Before Deletion Should users be asked to leave a feedback before deleting as seen in Fig.2 below? Users are more likely to leave very critical review on app deletion, but this kind of feedback will be very helpful for the developers to strengthen their app's weakness for next version release.                                                                                                 Fig.2: Asking user for rating before app deletion

I have 4 kids so the battle for time on the living room computer never ceases, I am also implementing an attempt at some level of control over how much time the kids get based on their behavior etc during the week. Ideally I would like to be able to set each profile up to have only a certain allotment of time, say 2 hours that they can use and once that two hours is nearly up it warns them and once complete it automatically logs them out.  I know the family control stuff can limit the time frames during which they can login but it does not seem to allow this quantity based control I am looking for...  Any other options in the market that you know of?

when I look at my Nexus 5 with android 5.1. battery screen, I can see something like this:    Screenshots (click images for larger variants)  Sum of all per-app percentages in list is 10. However as you can see, there is 60% battery consumed (40% remaining). So, what is the deal here? Who consumed 50% battery? Or what do the percentages next to apps mean?  As you can see, screen was on just for few short times, the same for awake, and yet battery life about 18 hours? I dont get it.  Also, I found this issue reported on AOSP, but noone from google seems to care:

I have 3 accounts that I am deleting - however, several hours after the 24 hour (+ grace period - end about 4-5 hours ago), the countdown completed, but disappeared and the accounts are still there.   I would rather not go through another 24 hours, and would like to have these accounts deleted (and yes, I have thought about it and this decision is not up for discussion).  Currently, the accounts are still there.  Could this please be seen to?
