I've noticed that when I close an app (exit it) it usually stays open in the background. An example for this would be Facebook or Google Goggles.
I don't want to have those apps drain my battery when I don't use them and I don't want to have to close them manually every time I exit them. What can I do?
Please help
Im doing the same thing too i would like to know if possible. I tried a taskmanager program but that just halts an app from coming back up again.

When any Activity is no longer the frontmost Activity (on screen), it's shut down by the OS. Any "background" Activities are simply stored in memory in case you want to go back to them. What you're seeing is essentially the history of the app; when you "open" it again it'll just reload the last saved state. At that point, the application is allowed to execute again.
The only applications that should continue running in the background are services.
The only drain you'll see are, as above, services running and the power necessary to keep the background Activities in memory; they're not actually executing.
Of course, there are ways to get around that, but most good citizens will respect Android's wishes when it comes to saving state and exiting when they're no longer frontmost.

So when I click the "Force Stop" in the task manager on one of those applications that I've closed, what does it do? I don't think it erases them from the memory.
For instance, Facebook, when I click "Force Close" I'll still get notifications.
I'm seeing some of these applications in the Battery Usage.
Furthermore, Android will completely shut down apps in the background in order to recover the memory they're using, if it's needed elsewhere. That's really the only time that app management is necessary.
If you're simply seeing a lot of "background apps", rest assured they're not draining your battery.
If you are seeing an inordinate battery drain while you're on the home screen, you might have a service running behind the scenes that's consuming your CPU cycles.
Look for System Panel Lite in the Market; it will let you see the amount of CPU being devoted to each process. I'd bet that most of your background stuff is only eating RAM and not CPU. If there is something eating up a lot of CPU, you can investigate that particular app instead of simply force-killing everything in the background.

There are two components to the Facebook app: the application itself and a service. When you "Force Close" the application, you're just stopping what you see onscreen. The service is still running, and a totally different animal than the application stuff we were discussing.
Edit: To clarify: You're seeing the package under Battery Usage, which combines the application ("Activity") and service usage to form an aggregate for "Facebook", not just one component.
Edit: (again) You're right above when you say that it removes them from memory. That, in fact, is ALL it's doing. It's removing the history/background Activities from memory. Unless that Activity is actually the frontmost Activity at that time you click "Force Close", it's not saving you any CPU time/battery usage.
Okay.
So you're saying there is no reason for me to "Force Close" every app after I've closed it?
And btw, when you say that they are in the background what does that mean?
I mean, the Active Applications widget is supposed to show me those that are running in the background right? So how come when I go to the home screen (using the back button) from an app like Facebook it won't show in the Active Applications widget but it will show Google Goggles?

To your first point, yes, that's exactly it. Android does this for you if it needs the memory. Otherwise, it leaves the history hanging around to make it appear the app is loading quickly the next time you open it (and it puts you right back where you left off). Note that we're ONLY talking about the user interface you see onscreen here, not any services.
Your second point requires a bit more explanation. My apologies if this gets either too basic or too in-depth; I'm not sure what your skill level is with Android. Each "window" or "screen" you see is actually a separate Activity, and is essentially self-contained. As you navigate through screens, the previous one saves what you were doing in memory and then exits. When you hit the Back button, Android simply grabs the last screen in memory and loads it back up. At that point, the application is running again. My references to "background" applications above is exactly this: screens you've left behind that are waiting for you to hit Back.
It's ultimately more complicated than that, but I think this will work for our needs.

To continue: Services are the real sticking point here. A service is an application that doesn't have a user interface (or screen). It's running all the time and not subject to the history/back button behavior we've been discussing. These guys are the ones you really need to be worried about, if anything. These are the ones that will run behind the scenes, consuming CPU and data (and, by extension, battery). Facebook is an excellent example: It's always checking to see if you have new messages, posts, etc. so that it can pop them up on the screen. GMail and SMS (and phone calls, even) all do the same thing using services. If the service is badly-written, it can be a real drain even when you're not using it.
You mentioned Google Goggles specifically above, and unfortunately, I'm not very familiar with how that particular app works. I suspect it's not subscribing to the good citizen philosophy and shutting down when you're done with it. It imagine it has to do with needing to perform searches or image comparisons in the background while you're off doing something else. This is technically allowed by Android, but it's frowned upon and suggested that you only do it when absolutely necessary.
Whew. All of that to say this:
Apps, as a general rule, don't consume resources when they're not on screen. They'll consume RAM, which does consume battery power, but it's really insignificant in the grand scheme of things.
Some apps will continue running after you "exit" to the home screen, but they should only do that as long as they have actual work to do. Once they're done, they should also shut down as above.
Services will consume resources all the time; they're constantly used for things like checking Facebook, Twitter, email, voicemail, etc.
okay, so again, just to summarize:
Force Closing an app just removes it from the System Memory (which makes them load faster when I open them). These apps use no additional battery life?
So I can feel free to not Force Close apps such as Camera (which I can do that to for some reason which I can't think of)?
Edit: And thank you very much Nick for the help and great responses.

You're correct. As a general rule, you don't have to force close any applications in Android. They will use some RAM and zero CPU and data, which equates to effectively zero battery.
Leaving the app in the background (in memory) loads the app faster the next time you open it, assuming Android hasn't closed it to reclaim that memory on its own. I've found that within a few minutes of heavy use (browsing the Internet, etc.), Android has shut down several of the apps in the background for me; it needed that memory to let me continue doing what I was doing.
You don't need to force close apps in the normal course of business. The only time you should force close an application is if it's behaving badly while on the screen (it's not responding to button presses or it's stuck in a tight loop or somesuch). Force closing it while it's in the background doesn't really gain you anything.
Okay, so just one last thing:
Do you have any suggestion to try and improve the battery life?

I have some general suggestions:
Don't sync accounts that you don't use. For example, if you don't use Facebook very often, don't have it set to sync up every hour.
Turn off WiFi, Bluetooth, and GPS unless you're actively using them. (A caveat: Google Maps uses WiFi in conjunction with GPS, so turn them both on while using Maps, even if you're not connected to WiFi.) Personally, I don't do this. I leave WiFi, Bluetooth, and GPS on all the time, but I know people who swear by this.
Keep your screen brightness as low as you can stand it. Again, I don't do this. I generally leave it on Auto-brightness.
Ultimately, though, you need to find that balance between usability and battery life. If you're always on Facebook and Twitter, sending SMS and surfing, well, there's not much you can do but keep an extra battery or charger nearby. If you're an office-worker that only uses their phone on break and at night, some of the above will probably help.
If you can give me an idea of a normal day's usage of your phone (and make/model/ROM version), I might be able to be a little more specific, or at least point you in the direction of your device's Q&A forum.
Well, I'm new to android and I've got a Samsung Galaxy S 2.
I don't really use the data connection (which is why it's always disabled unless I decide otherwise) and I turn on the Wifi only when I need it (which is often relative to 3G).
Normally I just use my phone for calls, SMSing and a bit of surfing.
About the google maps, I've noticed that it uses A LOT of battery and that it starts itself after I force close it, so I've closed the Maps service which seemed to fix the problem.
That's more or less it.
Not much syncing as well, I usually sync only when I need it.
Edit: I must say that I don't really understand what Backround Data is.
Is it that the Background Data lets the apps use data (like use facebook via wifi?) while the Auto Sync syncs automatically when I get a new email / notification? Does the background data have to do only with the my monthly data package and not with wifi ( i think that is the case ).
First off, you'll probably be better served to ask the guys in the Samsung Galaxy S2 Q&A Forum. They'll have a better idea of what the device's baseline is and what specific features you can turn off. Sometimes, as with the Samsung Fascinate, there are specific features that cause problems on the stock ROM, like Maps issuing bad WakeLocks. I know on my Fascinate before the first update, I had to toggle airplane mode every time I booted or Maps would eat the battery up in hours. Those guys in the device-specific forums will have a better handle on it, if there's anything of concern.
In general, though, it sounds like you're doing a pretty good job of keeping the device doing just what you want it to do. Android's sync framework is going to try to sync up all of your accounts essentially simultaneously whenever you turn on data, since it's probably been turned off for longer than their individual refresh intervals. You might want to turn off automatic sync on the service that you do use, so you can control those a little better when you turn on data to do something else.
Maps is a heavy data user and it makes use of GPS, which is going to consume quite a bit of power. The startup cost you're noticing is it trying to get a fix via the cell tower, GPS, and WiFi all at the same time, since the services have been off. If you use Maps often, you might be better served to leave data on (but, say, Edge only if you're GSM or 3G only if you're LTE/WiMax). This way, Maps can get a rough fix on your location at all times and not have to beat up the hardware to get a fix from scratch when you turn all the services on.
The Maps service is probably, to be anthropomorphic, freaking out all the time because it's trying to get some sort of fix while all the data services are off. Truth be told, I don't believe it was designed for that. Shutting down the service is a good way to go if you don't use it often.
You could try an application like Autorun Manager to control which services start up on boot. To make the most use of it, you need to be rooted, but in non-rooted form it will give you more control over what starts up automatically.

Background Data is what services use behind the scenes (like syncing and such), but I believe it's an aggregate of all data, not just data on the cellular network. I'm looking through the docs right now to see if I can find a definite answer.
Edit: According to the docs, Background Data is data that is sent or retrieved when the application is not onscreen. This can be either in a service (as is usually the case) or when the app has to do some cleanup after you've moved to a different screen.
Thank you very much
I've noticed that I've got a few widgets that are using memory etc, ones that I don't use and never intend to.
They were preinstalled with the phone and I can't seem to uninstall them. Is there a way that I could without rooting my phone?
And on another subject, if I root my phone, is there a way to "unroot" it in case I'll need to send it to Samsung if there is a problem with it (since i've got a warranty and rooting voids it?)

In theory, widgets don't consume resources unless they're on your home page. If they have services that collect their data, that's a different story. If you don't want them, you can just long-press on them and drag them to the trash can.
In conjunction with Autorun Manager above, you can remove the widget from your home page and stop the service from starting at boot. For example, I don't use Facebook (I know, lame), so I removed the widget and stopped the service. True, it's burning up a couple of megabytes of disk space, but that's insignificant next to the power of the Force, as it were.
Regarding uinstalling them, generally the answer is no. If you root your phone, you can manually remove them from the device, but that's sometimes overkill. Generally, they take up little enough room on disk that you won't be hurting for space.
In most cases, "unrooting" is as simple as flashing the stock ROM (usually available at the top of your device's development forum). Rooting your device generally doesn't make any changes to the device itself that can't be undone by flashing a stock ROM.
I've heard that rooting still leaves traces on the device though and that if they catch that it's been rooted I'm screwed. So you're saying that's not true?
I'm hoping this helps out I know with all the hype of the Thunderbolt there's quite a few users new to android that see how people are customizing and wanting to know, and repeat after repeat of questions and bringing a lot of unneeded hostility around here. Feel free to add what ever you guys think is something that is repetitively brought up. I'm running kind of short on sleep, so if I left anything out let me know!
Remember to always follow instructions and SEARCH SEARCH SEARCH before making a new thread
Remember to always Wipe Data/Factory reset/Wipe cache/wipe dalvik cache to insure a clean, fresh bug free install.
Also ALWAYS make a backup of what ever current rom before flashing a new one
Lastly, DO NOT treat the devs with disrespect they are losing sleep/girlfriends/what ever to give us these roms and kernels and everything else for free. If something gets messed up do not come at them with hostility or it will only be returned. The people of XDA will HELP you, but only if you've searched and tried to help yourself first. Also don't forget to donate to the dev's from time to time for their monster/beer/hookers and all their time and effort.

when you reboot the phone make sure you wait until you get a 3G/4G signal. If you start the process of setting up your phone to quick it will cause your phone not to activate the data connection.
2.) ROOTED my phone and at each boot made sure I had 3G/4G connection before setting up phone. (Downgrade and Upgrade).
3.) This let me keep my data connection all the way through.

How to help Improve battery life (Courtesy of Guitarchris123):
If you easily get a full day's use with stock settings, then ignore this. But the ThunderBolt is a powerful 1GHz smartphone made by HTC with a fairly small stock battery, large 4.3" screen, LTE capability, and Sense UI, so battery life may be a concern to you. There is no magic app or single technique that will make your battery last all day with heavy use, but if you utilize some of the following tips you WILL notice a significant increase in your battery life. Everyone's use is different, so 6-9 hours on one charge may be enough for some while others need 12-15 hours. Some of these may not be necessary, appropriate, or desirable for all users, so just pick which ones work for your purposes and preferences. You might prefer to keep using some of the particular features mentioned, as the benefit for you might outweigh the minimal savings in battery life. The point of this is to show people how to disable or limit features they don't need, not force them to shut down everything the phone was built to do. Feel free to add your own suggestions as well or ask any questions about the techniques.
1. Settings: (use an app or widget that helps you quickly toggle them, eg. built-in widgets, or from market such as Elixir, Quick Settings, or MySettings)
a. Screen –go to settings/display, turn down Brightness (20-30%), set Timeout to 30 secs, manually turn off by quickly pushing top button when not using anymore (instead of waiting). I have personally found that I like setting timeout at 1 min better, and manually turning off the screen with the top button every time I am done using it before I put it down or away in my pocket, that way it doesn't waste itself timing out or shut off on me when I don't want it to yet.
b. GPS – always turn off when not using, and plug into car charger (or car dock if you have one) during extended use
c. Bluetooth – always turn off when not using
d. 4G – always turn off when not using, only use when you need the speed, (the TB will get a toggle either in an update or in app form at some point, in the meantime there are several methods to accomplish this)
e. Mobile hotspot – always turn off when not using, plug into charger when in use if you can
f. WiFi – turn off when not near a WiFi signal for an extended period of time, but always use when available (faster than 3G, uses less battery), go to settings/wireless & networks/WiFi settings, press menu button and tap Advanced then WiFi Sleep policy and select“Never”, this sounds counter-intuitive, but it actually uses less power because when WiFi sleeps 3G or 4G wakes up to sync, get email, and retrieve other data (WiFi connection disables 3G/4G). Also uncheck Best WiFi Performance if its checked.
2. Background/wallpaper - use a static image instead of a live wallpaper (but these are cool, so use one if you really want to, they only drain for the short amount of time you are looking at the launcher screens). Many say the live wallpaper drain is minimal, but I noticed a significant amount while using a live one so I went to static. Have any of you tried both and noticed much of a difference yet?
3. Window animations – go to settings/sound & display/animation and select“no animations”
4. Keyboard vibration – turn off vibration function (haptic feedback) for when you hit a key (helps with speed too), go to settings/language & keyboard/touch input/text input and uncheck vibrate when typing, you can disable haptic feedback in other areas of the system by going to settings/sound, and uncheck vibrate feedback
5. Notification lights – unless you really want/need to know when something happens on your phone when you are not looking, go to settings/display/notification flash and uncheck all the boxes
6. Vibration – unless you really want this function, go to settings/sound, and uncheck vibrate
7. Monitor battery use - go to menu/settings/about phone/battery use, this will show you what is eating the most battery, uninstall troublesome unneeded app, use Running services widget by going to shortcut/settings (helps identify processes running in the background and foreground), if you want more detail check out SystemPanel in the app market, if you want to be alerted to "rogue" apps check out Watchdog Task Manager in the app market
8. Disable“always-on mobile data”– go to settings/wireless & networks/mobile networks, uncheck “Enable always-on mobile data,”you will still receive emails, texts, and phone calls, as well as internet usage, but it may cause connectivity problems in some third party apps (use manual refresh feature when opening apps to update online data)
9. WiFi and 4G network notifications – go to settings/wireless & networks and uncheck Network notification box (so phone will not constantly scan to look for open networks to tell you about)
10. Background data – if you are not using Google life-management services, go to settings/accounts & sync and uncheck Background data box (so that apps cannot sync, send, and receive data whenever it wants to, even if not currently using them). Add a homescreen shortcut to quickly toggle this (allows you to update/sync only when you want/need to).
11. Auto-sync – uncheck Auto-sync in settings/accounts & sync, or at least limit what apps are set to sync, it is better to manually sync/update/refresh in the app when you open it (set to update at launch), set update/notification frequency (polling schedule), if you do not want to turn off auto sync, just change widget or app update/notification frequency (refresh interval) in settings/accounts & sync to 30 mins or 1-2 hours, or better yet set it to update at launch, useful for Facebook, Twitter, Flickr, news, weather, Google apps, and stocks, be sure to manually sync/back up your contacts every once in a while in case you lose your phone or break it
12. Email – change sync option in settings, set email check frequency to 30 mins or 1 hour, or as items arrive, or better yet set it to never and manually refresh when you want to check/read your email
13. Camera app(s) – make sure they are not running in the background when not in use, exit/close when done
14. Video chat app(s) – make sure they are not running in the background when not in use, exit/close when done
15. Streaming app(s) – make sure they are not running in the background when not in use, exit/close when done, try to limit use or plug into a charger during use if you can
16. Google Talk – press Menu then tap All apps/talk/menu/settings and uncheck automatically sign in, make sure you exit the application by going to menu/more and selecting sign out when you are done (exiting the app by pressing home or back keys will not sign you out), if you want to receive IMs just open the application again
17. Adobe Flash Player – open browser, hit menu key, go to settings/enable plug-ins and set it to“On demand”(this way the browser only loads flash content when instructed to do so)
18. Update apps – hit menu key and to go My Apps to check for updates, even if you have selected“update automatically”because some apps require you to manually install updates (apps often get updated to use less power)
19. Location settings (updated) – go to settings/location settings. It is ok to have all of these checked, because it is the apps that use the GPS and consume power, not having these settings selected. GPS is only active when apps using it are in use.
20. Task killer – do not use them, uninstall if you currently have one, can harm phone and consume battery, just use back arrow key to exit apps instead of home key, simply monitor rogue apps instead and uninstall/replace. These are especially bad on pre-installed apps and services (many things rely on each other), so never "auto-kill" or "kill all." If you must use one, only use it on apps that you have installed that are misbehaving, otherwise let Android do it on its own.
21. Anti-virus – do not use them, uninstall if you currently have one, only download and use periodically or when you suspect a problem, do not download suspicious apps (check reviews and rating in market first)
22. Ad blocker – do not use them, uninstall if you currently have one
23. Battery meter accuracy – go to data/system and delete“batterystats.bin”after you have charged your phone to 100%
24. Tasker – can be used to automate settings (eg. based on time of day or app launched)
25. Juice Defender + Ultimate Juice – can be used to automate settings (eg. based on time of day or location)
26. Screebl - keeps backlight on while holding phone in "use" (vertical) position and turns it off when laying flat
27. Rebooting - reboot phone every few days
28. Delete unnecessary apps – determine which apps you do not need or use anymore and uninstall them, determine which apps you keep are causing the most battery drain and see if a comparable replacement from the market will do better
29. Widgets – turn off animations, do not use too many of them (choose them wisely), and delete unnecessary ones, they pull data in the background. At least make the interval/frequency of sync/updates longer for the ones you have. It may be better just to open some apps themselves instead of using the widget. Disable auto-updates on HTC Weather widget or at least set it to every few hours, manually update by tapping update icon on bottom of widget. Note that widgets that display battery, CPU, and memory utilization consume some power because they are polling the system for information.
30. No service – turn off phone or go into Airplane mode when you are in an area that does not have cell service
31. Chargers – have them handy at home, at work, and in car, and plug in when available. Try to get a 1A charger (same as included wall charger), many cheap aftermarket car chargers are only 500mAh and will not be enough to handle the GPS. VZW's car charger is 750mAh.
32. Rooting – (there are a lot more techniques that can be used with a rooted phone, such as removing bloatware and underclocking when then screen is off, but I will save that for a later thread)
33. If all else fails, buy an extended battery or have a spare handy just in case
Update1 - I came across another technique, it sounds a little strange but it apparently came from HTC regarding the EVO...some users appeared to have experienced gains from it:
34. "Calibrate" battery - (1) Turn device ON, charge it for 8 hours (or until LED turns green), (2) unplug and turn it OFF, plug it back in and charge for 1 hour (or until LED turns green), (3) unplug and turn it ON, wait 2 minutes, turn it OFF, plug it back in, and charge for 1 hour (or until LED turns green), (4) unplug it, turn it ON, and use normally. Repeat once a month or so.
Update2 - I found a few more things to suggest
35. Blockbuster app - open app, download update from market, then go to menu/settings and tap "disable movie updates." The app is set to automatically periodically scan for updates by default, and requires the new update to turn this off.
36. Friendstream - delete the widget from your home screen, open app and go to menu/settings and select update when opened. This way it isn't constantly refreshing, but rather only does so when you want to look at it by opening the app.
37. Signal strength - whether 3G, 4G, or WiFi, if whatever you are trying to connect to has a low signal strength the TB's battery will be draining trying to connect. Keep an eye on your connections, and try to be aware of when you are in poor signal areas and toggle off or switch connections if you can. Also keep in mind where your "fringe" areas are (ie. bounces between 3G/LTE/1X)
38. Apps - not all 3rd party apps are optimized for the TB, be sure to read reviews/ratings in the market to see what problems other users have had with them. Monitor your apps to see if any of them are hogging system resources (eg. CPU, RAM) and draining your battery, and delete or replace them accordingly. And remember to set the sync/update/notification frequency at longer intervals in settings within the apps that connect to the internet frequently.
39. Power saver - go to settings/power, and check enable power saver, the go to power saver settings and tweak (basically does a lot of the things we've talked about here for you automatically when you get low on battery, in case some things are left on or on higher settings than needed)

Thanks for that. I am going to have my wife read this so she can understand more on what to do with her phone, since it is not rooted and still has all that bloatware.
My phone is rooted and I have been testing with 4gLTE off/on, and seriously gained 5 hours when 4gLTE was turned off.
17-18 Hours Almost made it to 19 hours - 4gLTE off - This is with moderate use call/text/IM and some gameplay.
13-14 Hours - 4gLTE on - This is the same as above.
Trying now to talk my wife into letting me root her phone, but alas it is her phone and her choice.
Also if you want to update there is a 4G/LTE app in the Marketplace for the toggle - just search in the Market - LTE - it will show up as a Red Lightning bolt in a grey Circle.
Excellent post!

Ah, very good! I forgot about the toggle switch. Added and thanked!
Lots of good info, thanks
Awesome, thanks for the tips, should make my experience better.
This is a great post!! I def used some of the battery saving techniques.
Awesome information - wish I would have found this when I first bought my Thunderbolt... better to learn from others than trial and error method sometimes. lol
Thank you for the info... Somw i knew some i didn't... Great one stop for quick reminder..

Good stuff. Thank you.
Great post. Just one question. Why do ad-blockers use more battery? Wouldn't it decrease data use and thus battery since it prevents ads from being downloaded?
Thanks for the info!!
def a one stop shop. thank you. info much needed.
Sorry kind of falling behind on updates. Anyone think anything needs to be added???

Rooted with revolutionary...lost my gps CM7 ROM
Rooted my TB...with revolutionary, installed CM7 ROM. Now my gps doesn't work. Any ideas. Any advice?
I think CM7 has issues with GPS.
Thanks !!
Using Juice Defender lets me go a day and a half without charging. It's awesome !
Whilst I am aware that this happens occasionally at HTC's end, I just wanted to share some of the weird things that have happened recently.
The weather app is behaving erratically - have all location services enabled (bar GPS) and it refused to update the 'current location' when it auto syncs, or when I manually force it to sync. It has been stuck at the location I was in yesterday which isn't much use!
I have tried deleting the widget and reloading etc.
The only thing which makes it update is if I turn off 'Fastboot' and do a power cycle, then it works?
Anyone else had the same thing? Anything obvious I am missing?
Are you indoors? If so try to turn off GPS sync. That might work.
If not then navigate to menu> settings> applications> manage applications> all> and find weather widget, weather, and weather provider. Tap each one and choose Clear Data or Clear Cache for each one as needed. Then soft reset the phone by powering off, remove the battery for at least 30 seconds, replace it, then restart. This will ensure that all of the cached data and device RAM is cleared, and that your connection to your mobile network gets refreshed.
Hope this helps
Sony xperia Z3 Dual D6633 Android 5.0.2 Build 23.1.1.E.0.1
Hi there,
Upgraded my Z3 to lollipop last week and, despite the fact that the upgrade itself was flawless, I think I went from a device that used to work like a charm to one full of annoyances.
On day #1, noticed the batt drain skyrocket. 3h after disconnecting it, it was at 68%, half way through the morning. WTF? was my first thought. On a typical day on kitkat, I was able to end the day at 40% at least.
The second thing I´ve noticed was the phone app. It starts giving me errors, saying that the "network could not be reached" when I try to dial a number. If I insist for 4, 5 more times, it crashes. Dialing is only possible again if I reset the phone.
The third thing is the lock screen. It seems that lollipop has a drop down menu that makes it possible to enable/disable lots of things, like communications and even setting the phone in airplane mode. Imho that´s a huge liability / security risk and it appears that there is no way around that.
Still about the lock screen, it seems to have a bug: if you have any activesync account setup, not notifications will show up, no matter how you configure it (to show all or hide sensitive content).
So, I had only one thing to do, after reading forums etc... factory reseting it.
Surprise! All problems are still there.
Does any1 have any tips on those?
Thanks in advance.
There will be a widget on one of the screens which keeps refreshing itself and I found that to be the battery killer on my 6603.
Did you use any specific app to pinpoint the culprit?
1. It is possible that the battery levels are calibrating and will be imprecise for a while after the update, using the device normally for a couple of days will fix it, or at least this is what I observed in many phones I owned.
2. This is very weird and I can't help you with. If not even factory reset did help you may have some corrupted data on one of your contacts maybe? Try to make a thread about this issue on the Sony forum.
3. I noticed that as well, but even on pervious versions you could turn off the phone so I don't think it changes anything. Make sure to disable the multi user options that would allowanyone to add a new user from the lock screen.
4. Another weird thing, I use exchange accounts on my phone and I don't have any problem on mine. See point 2.
Under
settings>sound and notifications>when device is locked
Set to hide sensitive notification content or don't show notification content at all.
This should fix lock screen displaying email notifications from your exchange account.
Also, unlock phone, pull down notifications, pull down again to reveal quick settings, hit the edit button (pencil) and remove icons but clicking and holding and drawing them to the top. Unfortunately this removes them even when phone is unlocked but of your worried about unauthorised toggling of things on off its the best you can do I think.
As for battery drain, check the battery usage in
Settings>power management
Make sure stamina mode is on, toggle it off then on to make sure.
Select battery usage and check to see if any apps are using more than they should. Make sure brightness is set low but enable adaptive brightness under display settings.

That's not a smartphone anymore, with all functions shut down and brightness low.
This phone has the best screen, use it at least 50% brightness.
I have no issues with the brightness down. It bumps up nicely in brighter conditions and will even max out in daylight. If I ever need it brighter then it's easy to boost temporarily. It's a small price to pay for nearly 24 hours of battery with 5 hours screen on time.
I never mentioned shutting down functions. The only thing I mentioned removing was the toggles that concerned the op on the quick settings. Removing mobile data and aeroplane mode from quick settings hardly cripples the device, I never use these anyway.
I don't think it very useful that there's not more customisation available here such as a complete set of separate lockscreen settings. But if all you can do is comprise then what else can you suggest?
I don't think unlocking the bootloader and installing a custom ROM is something the op wants to do.

You said stamina.
Stamina means already some functions off.
Update:
1. Batt drain
Remains without an explanation. My daily use profile is basically the same as before the update. 3PM and I am at 28%, with stamina on. I can´t recall a day, running kitkat, that I would hit the charger at night with 28% of batt remaining (and I still have 4h to go). It was always on 40% ish. GSAM is reporting that 47% of the batt drain is caused by apps and, from that, 30% is represented by android core apps + android system + kernel. I might be wrong, but I think it is related to reindexing, contact + agenda sync etc and it will probably get lower eventually (I hope!)
2. Phone App giving errors
I think I have isolated the problem. It seems to be caused by TrueCaller.
3. Lock screen
Regarding the drop down menu, It is clear now that what I think is a problem is, in fact, by design and there is no way around it without rooting. But regarding the notifications, I just removed both activesync accounts and I started getting notifications in the lock screen again. So, my guess is that there is a policy of some sort that is being interpreted by the phone as it should hide all notifications from the lock screen.
In fact, there are lots of things that got blocked / disabled because of those policies. Here is a list of things that were disabled and now appear to be working again, after the removal of the activesync accounts:
. notifications are showing again in the lock screen;
. smart lock;
. screen lock options (none, swipe, pattern);
note: I thought that I would be able to enable services in Accessibility, like LastPass or App Advisor by Norton, but it still does not work (I try to enable any of them, but pressing "ok" on the warning dialog does nothing and the only option working is "cancel").
Thinking about resetting it again...
Hi, if problems are persistant you can always downgrad software at KitKat by using FlashTool and wait Lollipop 5.1 (5.1 will probably solve many problems).

A new firmware version has dropped for the Z3 which I think fixes your issues with notifications.
I received it OTA yesterday, I'm running the Balkans customisation.
Thank you for the tip! I hope it does! Will keep it posted here just for the reference. I am starting to feel other "symptoms" as well, like bluetooth instability (you pair a device and it stops working, have to pair again).
.
Just hit another weird thing.
I am not being able to create a new vpn connection. I am trying to use the PureVPN and IPVanish client software, but when I try to setup the conection, I receive a disclaimer, saying that my traffic might be monitored, with a "CANCEL" and "OK" options. The OK doesn´t work, only "CANCEL".
My device is encrypted and I have also noticed that I am not able to decrypt it.
Also, If I go to Accessibility and try to enable a service, the same thing happens: a disclaimer appears, saying that the service might observe my actions, with a "CANCEL" and "OK" options. The OK doesn´t work, only "CANCEL".
Any ideas?
Ok, just a quick fup: the ability to create VPNs from apps is disabled if you encrypt the phone. It seems that if you create if before encrypting, it won´t be disabled; but you wont be able to create a new vpn from an app downloaded, after encryption.
Regarding the Accessibility > Services, after a *lot* of research, I have found that Twilight was the culprit. For the reference:

* Often when I work the mobile is at my desk but I still comunicate by sending SMS and using Whatsapp in my webbrowser. Works fine with Samsung and Huawei but with my new Mi10 Ultra id does not work. Connection is lost and I have to tuch some key on the phone to light up the screen and then it syncronizes.
I have set permissions for the apps to allow both autostart and not affected by the battery saver in the system.
I have also set the "data usage" for the apps to allow background data.
...but still, background data for SMS and whatsapp IS deactivated until I light up the screen.
Has anyone run into this problem? Is there any general (mayor) switch for this that I have missed?
This happens to me with Gmail. Sometimes they come in on the lockscreen and sometimes I have to turn the phone on for them to appear. I still have this problem on my Samsung S20 Ultra but I learned to live with it since I never figured out what the problem was. I have no such problems with my SMS or WhatsApp though. Everything else for me seems to be coming through.

Hi there. I pretty much have the same problem with this phone. If it's not permissions nor background data, it's the power saving feature, which is the most aggressive I've seen yet.
I was talking with someone about this in another thread, but I was instructed to turn off battery saver. It got better for a day, but it kind of returned back the way it was. I think you could try and play around with the power saving settings for the apps you want immediate notifications from, which I haven't had time to do. Please let me know how it goes for you and I'll find time to play with it this weekend.
