I'm trying to figure out what's using my battery life by looking at the battery page in Settings. (I don't know if this screen is Cyanogen specific, or a stock Android feature.) Here's a recent screenshot of that page:    Transcript:     Current battery level: 67%      Use since last full charge:         Android System: 3%   Screen: 2%   Cell Standby: 2%   Ironclad Tactics: 2%   Google App: 1%   Android OS: 1%   Google Play Services: 1%      (It may not be clear from the screenshot, but that's the end of the list: there's nothing off-screen.) I don't know whether those percentages are supposed to add up to 100% (logical) or to 33% (the amount of battery used so far), but either way, they actually add up to 12%. No amount of rounding error can explain that. At best, 2/3 of my battery usage is totally unaccounted for.  This is a common occurrence. I have another screenshot where my battery level is 18%, but the sum of all the used apps is only 44%.  What could be using up so much battery that wouldn't show on this list? Or alternately, could some battery usage pattern could cause this screen to grossly underestimate usage of a particular app? Or could a faulty battery, that drains more quickly than it should for a given load, cause this?
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:
Is "forte" pronounced "fort" or "for-tay"? I've always heard people say something like     "Pronunciation is not my [for-tay]"   ... but I feel that I've heard that the correct pronunciation is     "Confusing people is my [fort]"   What is the proper way to pronounce this word? Under what assumptions can a semigroup $(S,*)$ be embedded into a group? How to split numbers into columns with negative and positive values, without empty cells? How to properly write multiple authors in bibtex file? I use  to store all articles I need and bibtex4word add-on (in MS Word) to maintain the reference list. So, I would like to know how to properly fill the "author" field in Jabref with multiple authors to appear them correct in the reference list.  For example, I've got the article with several authors:      E. Orti, J.L. Bredas, C. Clarisse   And I would like them to appear in this manner. But instead I get this:     C. C. E. Orti, J. L. Bredas Is there a cross-browser onload event when clicking the back button? Why does the series $\sum_{n=1}^\infty\frac1n$ not converge? Can someone give a simple explanation as to why the       $$\sum_{n=1}^\infty\frac1n=\frac 1 1 + \frac 12 + \frac 13 + \cdots $$   doesn't converge, on the other hand it grows very slowly?   I'd prefer an easily comprehensible explanation rather than a rigorous proof regularly found in undergraduate textbooks. Why do not we ask negative questions without a contraction on the not after the verb? I have found multiple questions touching on this but not a single one that has a comprehensive answer. The information is all there but in little bits.     etc.   Exactly why is "Do not you sleep?" ungrammatical (except in poetry/with artistic license)? I understand that not can't contract after you: "Do you not sleep?" because not can only contract after a verb, and that it always does after do: "Don't you sleep?" but why does it (why must it) contract if it's placed after the verb in a question?   Don't you sleep? (common form) Do not you sleep? (ungrammatical) Do you not sleep? (less common form) Launch shell scripts from anywhere Is it possible to run my scripts located in ~/scripts from anywhere?  Say i want to run ./scriptname regardless of my current working directory. How can I sound proof bathroom walls? I'm trying to figure out the best, least intrusive way of sound proofing the walls of a bathroom. The bathroom shares a wall with my bedroom, and my 3 yea old's bedroom. The main problem is the sound of water running (plus every bump on the counter and everything) echos loud and clear through the wall into my sons room.  I found  and it seems like a good choice. Another option is adding another layer fo drywall with something like  between them. But all the walls and ceilings in the house are textured. So replacing just one or two walls in a room is just not possible.   This is the layout of the two rooms. I've added red box around the wall with the most noise.   Is there anything else I'm missing here that I could do to dampen the noise short of tearing the bathroom apart?

I am a user on Stack&nbsp;Overflow, and I think every page that shows questions, display all tags and the questions. Are the tags saved in a tags table or are they included together with the questions table? I tried to find an answer to this a few years ago, but it seemed it wasn't possible then (I suspect it isn't now either! - but what the hell!)   I have a three monitor system, that I mostly use for remote desktop. However occasionally it would be useful to have remote desktop on two monitors and use the other monitor for the local machine.   I know it is possible to have a single monitor full screen, or to stretch an RDP session across monitors, but this loses things like snapping etc.   P.S. this is a duplicate of  thread, but that was a couple of years ago, I'm hoping things have changed. How to create a link to a URL provided in a bib file with custom text Using biblatex, how can I get a URL from the bib file so that I can use it in the \href command?  I am guessing that the \usefield command is what I am looking for and that in order to use that I would need the \entrydata command. But both are undefined.  \documentclass{article} \usepackage[backend=biber]{biblatex} \usepackage{hyperref}  \usepackage{filecontents} \begin{filecontents*}{sources.bib} @online{biblatex,     url = {http://mirrors.ctan.org/macros/latex/contrib/biblatex/doc/biblatex.pdf},     urldate = {2018-02-02}, } \end{filecontents*}  \addbibresource{sources.bib}  \begin{document}      % This would work, but I don't want to duplicate the URL from the bib file:     \href{http://mirrors.ctan.org/macros/latex/contrib/biblatex/doc/biblatex.pdf}{biblatex documentation}      % Does not work because \citeurl{biblatex} is already a link, not the URL:     %The \href{\citeurl{biblatex}}{biblatex documentation}      % Does not work because \usefield and \entrydata are undefined:     %The \entrydata{biblatex}{\usefield\href{url}{biblatex documentation}}      \printbibliography \end{document} Debugging errors of SAGA interpolation algorithms in QGIS Processing? I encounter recurrent problems with the geoalgorithms that perform interpolations. No matter what technique I use I end with the following errors. As stated in the OGR tab QGIS 2.0 is unable to open a file in C drive. I have very little IT background so the message error is meaningless.   Is there anybody able to decrypt the message and solve the problem?      here this is the algorithm i used Insert data only if record does not exist What do the X and Y axis stand for in the Fourier transform domain?
