Hi I have recently bought a Sony Xperia c1505. Phone Details: Sony Xperia c1505 1.) Model Number ? ____c1505_______ 2.) Firmware Version ? ____4.1.1_______ 3.) Baseband Version ? _____76XXU-USNSKOLYM-2540______ 4.) Kernel Version ? _____3.4.0-perf______ 5.) Build Number ? ____11.3.A.0.47_______ Also do you have a T-Mobile Data plan on your PayAsYouGo or FlexPay Plan? _______No_________ Carrier ? ______Talkmobile_________ (we know some are also Unlocked so not Just T-Mobile) Country you are using your phone in ? _______UK________ (we know that not everyone is from the US) Is the phone SIM registered in T-Mobile as the Correct phone? Not with T-Mobile. Talkmobile is run on the Vodafone network This is the first time I have had a smart phone and two things I noticed immediately when I started using it - first I had to re-charge it a lot and second there was a whole lot of stuff running on it that didn't want. A little later I discovered that unwanted apps also had a habit of using data behind your back. I'm trying to get some understanding and control over what is running on the phone, so I can reduce power consumption and know/control what's consuming data, but I'm struggling a bit with this. This is what I have done/found out so far a)I can do various things on the phone itself to reduce power consumption: Reduce display brightness, reduce screen timeout, only turn on wireless, Bluetooth, GPS when required,turn off phone vibration, turn off notifications. Doing these things has made a big difference to the power consumption. b) I discovered you can go to Apps, click on the App and 'force stop' or 'uninstall'. However many of the apps are not actually listed in the apps list and those that aren't, it seems, cannot be removed. Also 'force stop' does not seem to work on some of the apps. c) From further searching I understand that only if you root the phone can you actually delete/uninstall many of the unwanted applications. However I also understand rooting the phone invalidates the warranty (and probably also leaves the phone more exposed to malware?). I'm not too bothered about the applications being there as long as they are not running so I hope I can do what I want without having to root. d) You can go to settings->Data usage and turn mobile data 'off'. At the bottom of the screen there is a list of applications for which you can select "Restrict All Data" or "Restrict Background Data" to restrict mobile data. e)I have downloaed Power Tutor to help me determine what is consuming the power on the phone f) I have downloaded Terminal emulator, but have not yet used it much. I seem to be able to do some things (ls,ps,cd), but I think I need to explicitly download tools like grep/find etc. (the little searching I've done suggests I need root get hold of these - hoping this isn't actually the case) g)I have read various articles regarding the philosophy android has of keeping task processes "running", keeping then in memory ready to go, in the background when they are finished So I have a few questions: 1) Apps running on my phone When I run power tutor with WiFi turned off and leave it running for a while it lists various applications as using power even though I am (as far as I know) not using them. a) As I understand it android keeps processes in memory ready for use, but should such applications register as using any power ? b) If so how do I know whether they are "active" or not ? And how can I ensure that they won't start doing 'stuff' in the background that I might not want them doing ? c) The list of items I see using power tutor looks something like this(the list changes, and extends, over time): System Kernel Xperia Diagnostics Lock Screen Xperia Keyboard Radio subsystem Tools Messaging sys_9999 sys_1019 sys_1017 app_10137 Media Server Phone Contact Top Contacts Google Account Manager Google Play Store Google+ Maps Google Search Google Partner Setup (Norton Utilities) Package Access Helper Sony Select Lock screen Customisation Provider Facebook FBiX Proxy Calendar Storage Calendar SecureClockService InfiniteView com.android.sms.push Friends' music and video Update Centre Storage capability Download Manager Package Access Helper You Tube Picasa uploader Camera Devices Is there any way of knowing which of these are essential or integral to the working of the phone ? d) Occasionally I get listed an app named sys_<4digitNumber>. Does anyone know what these are ? e) I am struggling to find a way to disable some of the apps on the phone. I can look under Apps and "force stop", but many Apps (for example Facebook, Maps, Sony Select, Media Server) are not listed. Anyone know how I can disable these applications ? 2)Controlling and monitoring data usage In Settings->Data usage you can select to turn off Mobile data, which I have done. However I still seem to be getting some data reported on the data stats. a) Does anyone know if these stats include data over WiFi as well, or is it just reporting Mobile data usage ? b) Is there a way of configuring what stats are reported ?
