Memory/ RAM Utilization Increases When Not In Use - Touch Pro, Fuze General

When i start my phone its reported at 34% via task manager after a few hrs without using it AT ALL, its at 40%. I would figure if i had used programs i would have used up some memory but nothing not even a call.
Is this normal for the ram to get used up when not in use?

Well, your phone does things by itself, by checking for weather updates, email, phone resources, calendar/alarm checking, etc.

ya but i agree with him, they should be some time of timer on idle pgrams like a 1 hour grace period and after that hour is up, if the program is not used, it quits itself and releases the mean memory hold some of these programs have on our phone

The Touch Pro has more RAM then you will ever use (on it, not future devices). Just don't worry about it and it'll be fine.

I have all of that turned off, no data, no alarms or anything. Just use the phone for calling.

Sure fire way to stop background programs from running?

I'm attempting to try to increase my battery life so it lasts longer than 12 hours (~13 seems to be my limit). (I'll admit I'm a bit jealous of those who can run the phone 24+ hours) Though it's somewhat painful, I'm shutting down most the programs I have running in the background. However there seems to be a number that like to restart even after I think I've disabled their startup, widgets, notifications, etc.
Is there a way to make sure programs that you install don't run? Or at least don't launch during start up? Perhaps something like msconfig in windows?
Thanks.

Killing background tasks will only decrease your battery life. When an application goes to the background, it sits in memory but does NOT consume any CPU power. since the memory is in solid state, it requires no power to stay in that state. By constantly killing background applications, it will need to start up, reinitialize, and consume more power then if you had just left it alone. Also, long term performance will be negatively affected, even if you do expereince a small short term performance gain. the Android OS is designed at the core level to have applications behave this way, and modifying that behavior will make for a worse experience.

Eh, this is the first I've heard this. I don't remember reading this in the various battery optimization guides.
Still is there a was to stop things short of uninstalling? For example, I want to stop using the Yahoo Mail app but don't want to install yet. I went through all the options I could to disable checking/notifications, etc but it still pops back into memory constantly.
I assume youve tried the obvious, turn off WiFi (3G) and screen when not actively using it?! Those are the big batt.-eaters

Documentation? As far as I have read an application does not go into any type of dehydrated state when running in the background / minimized. It can do anything it wants including using CPU cycles.
I do agree that most applications do not need to be killed with a task killer but leaving 3D games (for example) running in the background could hurt your battery. Also not all applications are progammed with ther same fore thought and skill level.
I get about 33% more runtime out of my battery using a task killer to kill specific applications that I know I do not want running in the background.

I leave wifi on since I'm usually in range. It's more efficient than 3g right? I alway sleep the device when I'm done. I still have huge percentages on the screen when looking at the battery usage. I'm trying a completely black screen now.
Mainly your widgets and icons and stuff still cover large portions of it, so: a black screen will help, not but alot.
Also, to keep items in RAM, to the second poster... What do you think is keeping those items in RAM?
Ummm... It's the CPU.
Task Killers won't help you on RAM usage at all (Because Android will automatically shuffle them out if it has to, or so I've read... I've yet to hit max memory). Task Killers DO help you as far as battery use goes, though... Keeping the browser killed if you aren't using it, etc.

I should clarify. I guess the term I meant to use is "suspended." If a program is actively "running" in the background, it will use CPU cycles. But if you simply stopped using a program, say for example the xda app, and returned to your homescreen, the application stays "suspended" in the background and consumes no CPU cycles until you go back to it. Now services that are updating, such as email or SMS, will use CPU cycles in the background because they are still actively running. But if you want to conserve battery life you can simply disable the notifications from most of these programs.

The app itself at that point may not be but the Android OS still does to maintain that suspended state.
I have some applications I rarely use or even some that I've never used but may want to in the future. I see absolutely no benefit in keeping these applications in the background. Further more, I've noticed a signficant drain on the battery when extra applications are running in the background. I'm sure it's not all of them, but I've yet to discover who exactly the culpit is. Right now I suspect it's the NPR app, perhaps due to data use?
The point is, there are perfectly good reasons to keep some apps in the background, and perfectly good reasons to kill others - or perferrably not have them start up at all unless I do it myself. Could be due to data usage (especially if you do not have unlimited data), could be due to concerns about excessive cpu usage. There really should be a clear method in which you can stop applications from opening on their own.
You can use the program "Autostarts" to keep applications from starting at startup. With it you can also prevent things from launching under a number of other situations. That might be what you are looking for. Just do a google search for the APK as I don't think it is in the market.

To me, it's not a matter of "task killer or not", but rather when and where to use one. And I think it's simple: Don't bother, unless you suspect a specific app is doing something you don't want it to do in the background. Then, just kill that specific app and leave everything else alone. A Task manager that shows CPU% for each process can be handy for this as well.
I generally try to avoid killing tasks, but one night I had 50% battery on my phone and after about 2 hours or so I took it out of my pocket to make a phone call, and it was very hot and had about 12% of batter left -- something was running wild that shouldn't have been (I think it was Pandora, even though it was not currently playing any music!) So, background apps do occasionally run out of control, and you do need to occasionally kill them, but do it on an "as needed" basis.

Unless the background process is syncing data, it won't eat your battery. So instead of wasting your time, you should focus on other energy hogs. Things like screen brightness, bluetooth, wifi, and gps.

I installed Advanced Task Killer from the Market. It lets you kill all running applications including itself.

Or an auto-killer would've killed it before it killed your battery by 38% lol
Task Killings are bad, mmmkay...
Slightly off topic:
To help conserve battery power,
Use an all black desktop background since the black areas dont use battery power.
Hmm, people in this thread have said a few things that I haven't heard or seen much before. Specifically that killing apps could decrease battery life. When I first downloaded advanced task killer I tended to kill most things. I slowly backed off and now I've been watching what launches and what tends to come back and not kill those (mail apps, widgets, performance watchers, etc). The second is that not having a black background doesn't necessarily improve battery life. Makes sense considering I have icons everywhere on my screen.
@Shuggins - Thank you! That's exactly what I was looking for. I've downloaded it but now I have to, er charge my battery a bit before I can take a close look at it.
@jsmith8858 - Are you running setCPU? A couple days ago I noticed my battery running pretty hot. I stopped using setCPU and the battery cooled down a lot. I've used setCPU since them without the heat issue so I'm not sure what was going on.
Well during todays iteration I ran for about 12 hours (typical). I had a couple short phone calls, 2 email accounts syncing as well as other bg syncing processes. I did eat up 30% in an hour messing with a game. I'd probably have 13-14 hours if I didn't play anything (but if I didn't what's the point of the phone . Still, as much as I love it the screen is killing me. Guess there's nothing to do about it though (usually brightness is all the way down, turn it off when I'm not using it, using a darker background). I didn't kill any of my background processes today. I'm going to set up that Autostarts program and start auto-killing various programs tomorrow.
You can try using autokiller and art it to extreme, but I don't recommend this

Guide to Maximizing Battery Life w/o Disabling Half Your Phones Features

*Disclaimer* This is all from a personal experience and testing/research from a long time android user, what I have discovered over time and has helped me and some friends. This will work whether your rooted OR not. I kept it as basic as I can so everyone can benefit. If you dont like what you read and disagree, or want to add something PM me, Ill change/add and give credit to you. Hopefully, this can grow with the community.
*Rooted Section Will be Added*
*When I charge my battery I usually drain it all the way down or as much as i can (around 20% left) then charge plugged in till green, then power down and charge for another hour or so. Not sure if this matters or not but seems to help me out try it!*
This guide will help you if your rooted or non-rooted, all the apps I talk about I honestly have no ties to the devs. I don't use any SUPER AWESOME AMAZING BATTERY SAVER 5000 apps or anything like that. Those mostly just turn ur radios off and on and kill apps in the background. In my experience a lot of them cause syncing issues with my e-mail and other notifications. I like to receive my information instantly not have an app waiting for me to turn my screen on to check for updates.
About my personal setup: Basically, I want my phone to last me all day but still perform well with a heavy use, WITHOUT needing to constantly change settings to save battery. With what I have here Im able to keep my Sensation running for a full day of moderate-heavy use (7:30am to around 10pm) with its STOCK battery (Did damn well on my Evo 4G too). Days of very minor use Ive gone into the second day with 60% + battery. Yes, I use all my home screens and have a good amount of widgets, I love sense and its widgets. I play games, surf the web, do a lot of texting, listen to a lot of music, decent amount of fbing and email, usually take a few pictures a day. Half my day is wifi/other is mobile data.
Here goes the real basics, mostly common sense here not trying to insult anyone. Feel free to browse thru it quick (green text) if your not totally new to the android scene, whats after it will be a good read for noobs and vets.
*I use the power control widget, make getting to a lot of settings quicker. Why waste battery digging thru menus?*
Basics:
-Screen brightness: (duh ) these pretty screens eat battery brighter=quicker drain naturally and from my experience leaving it on Auto Brightness kills more battery too. Each time your phone pulls information from the sensor to decide on how bright it should adjust itself too.
-GPS: If GPS is on it should not effect battery unless an app is using it and you see the GPS icon on your notification bar. I noticed a very slight increase in mA discharge when i had it enabled, to be safe leave it off if you dont use it extremely frequently.
Location thru mobile networks: Not to hard on battery. I leave mine on it does add drain but it takes away from my weather widgets updating when Im traveling.
-Bluetooth: Moderate battery drain. I honestly don't use it at all myself but if you do try your best to keep it off when not in use.
-Wifi: Android has gotten a lot better at managing wifi over the past few years. It doesn't drain that bad on battery and it shuts off/on periodically on its own when screen is off depending on whats using it.
Google Back-Up: Takes a little juice here and there no biggie. I dont use it just because I like to fresh install my apps when I try a new rom, run into less problems that way.
2G/3G/4G: This varies phone to phone, the slower speed the better battery life. If you know your not going to be using 4G for a while turn it off. I leave mine on 4G or wifi all day with my sensation. When I had Sprint and my Evo I would leave it off most of the time. Depending on your carrier and how their data works this is a big one. T-Mobile seems to handle well, Sprint and Verizon's 4G Ive seen eat an insane amount of battery.
Sync/Background Data: I lumped them together because sync is pretty much reliant on background data. These kill a lot of your battery in general. It syncs your apps (email, facebook, google data, contacts, etc.), the periodic checks your apps do to check for and download new emails and notifications, using background data (data still transmits when screens off). I always leave these on and still manage great battery life, I like things instant if I wanted to wait Id just wait till i got in front of a PC. Sync and Background data are the settings most battery saving apps control because they really can help your battery if you turn it off. You can control what core apps sync in settings>accounts and sync. Or the power widget that 95% of android phones have has it on there. I recommend minimizing the amount of apps you allow background data with, example: WeatherBug first launch it asks if it can automatically update itself in the background for apps were thats not necessary hit no.
Radio/Airplane Mode: Pretty self explanatory, turns off your connection to your wireless provider. No point in ever turning it off in my eyes, your phones no longer a phone.
What has really helped me with my battery life (non-basics):
There is a lot to be said when it comes down to 2.2+ android phones and whether they need a task killer anymore or not. Since Ive had a lot of android phones and a few now that are 2.2+ Ive done a lot of testing. I usually go about a 2 weeks on one idea or new task killer and keep a close eye on battery drainage using Battery Monitor Widget, free app in the market. It tells you exactly how much of your battery is being drained without killing battery itself. Each phone/rom settles at a different average mA lower the better. In my experience if I can keep my phone anywhere under 100mA when idle im doing good. This held true on both the Evo 4G and my Sensation. Some ASOP roms i could get down to the 30's but for sense under 100mA is good. Keep in mind you will get the occasionally spike here and there its just android and/or apps in the background. You can view the a chart of the battery data in Battery Monitor.
Instead of boring you guys with each task killer Ive used and its results, Ill just get down to what I found out in the end.
Basically, the way android 2.2+ works it really isn't necessary to run a task killer it does a decent job removing apps from memory when you need more memory. But at the same time I found running a task killer periodically (BUT not killing frequently used apps) results in a lower average mA drain leading to overall better battery life.
The best application I have used has to go Automatic Task Killer , trust me Ive used a lot from the top free ones to a few of the more popular paid ones. What this task killer does is kill a selection of apps you allow it too every time your phones screen shuts off and goes idle. On Automatic Task Killer's first boot your shown a screen of every application that could at some point run in the background on your phone. This part sucks a little bit but it is worth it, you need to select which of the apps you want to allow it to kill automatically. It does not kill foreground apps the ones you currently have open on the screen aka a browser or a game. Example your playing NFS: Shift and your boss walks by so you quickly pause and hit the power button turning off the screen, next time you turn the screen on it will kill all other allowed background apps but your game will still be up front and center.
Now the trick is to go thru and set it to kill apps you know your phone won't automatically just restart or you don't use 90% of the time. So don't select things like Dialer, Contacts, Clock, Calendar, Messages or apps you constantly use/check such as a third party SMS app or your main E-Mail Client or third party keyboards (various by person and what you use most). Letting the app automatically kill those is just going to lead to worse battery life because your phone will just restart it each time leading to more CPU cycles (not what you want and part of the reason some consider task killers bad things).
Also, when using any task killer and killing the proper apps sense runs smoother, a big deal with sense 3.0.
So hopefully with a little messing around you can get a good setup where your phone lasts you all day without having to constantly keep changing settings and watching your battery life. All while everything stays syncing and instant. Hope this helps!
*ROOT Section (now that we have s-off )
Everything posted above can be done on any rom, rooted or none. There has been a lot of posts on "freezing apps" that you dont need or typically use, which does in fact really help battery life. Since, we (by we i mean sensation users) now have a permanent root this is my tiny second part of the guide for rooted devices.
I dont freeze my apps I prefer them to be gone for good if its something I dont see myself using or its bloat that came with my phone/rom. Since 98% of us will be using custom roms now this usually isnt an issue since most dev's r good at what they do and remove all the bs we dont need or normally use. Still there is some apps we may not want on our phones so for that I use SystemApp Remover . Its a great App for people who dont want to have to worry about going in manually and getting rid of system apps.
Its just basically an Uninstaller that allows you to access any and every app on the phone for you to uninstall (thats y roots needed). For me I just go in an drop the apps I know i wont use. A lot of roms come with carrier add-ons and such, those I normally delete as well as a few HTC sense widgets and apps I see no need for. It will free up space and increase your phones battery life with most things you delete.
Now, be careful. You are prompted upon opening SystemApp Remover that messing in system apps is dangerous and it is. If your not sure what something is DONT touch it, simply do a google search or ask around to see if its safe to remove first.
Re-calibrate Battery: After you flash a new rom or start using a new battery, you should use your recovery (CWM or other) to Wipe Battery Stats. Before you do this make sure your battery is at 100% and has been on the charger for over an hour with the fully charged green led on. This will allow your device to better drain your battery and can really help battery life.
So hopefully with a little messing around you can get a good setup where your phone lasts you all day without having to constantly keep changing settings and watching your battery life. All while everything stays syncing and instant. Hope this helps!

i havent really bothered with task killers but ive found reducing the brightness and disabling data and sync makes my battery last alot longer. i just re enable when i need them.
also, i downloaded setcpu and added a profile for while the screen is off. that helps alot. the drain is about 5% with the screen off after every 3 or 4 hours.

Full version is much better.
It's killer app indeed. I think many of it's features should be natively included in android.
Options like "Turn off 3G/EDGE when connected to Wi-Fi", "Turn off all radios when screen is off", "Turn off Wi-Fi after x minutes if it doesn't connect to a network", "Set screen brightess to minimal when battery is low", etc....it wouldn't be that hard to implement and battery life, perhaps most criticized aspect of Android, would improve immensely.

Your mobile network DOES turn off when connected to wifi, and if all radios turned off when the screen went off, how would you ever get calls or emails with the phone in your pocket? The wifi after x minutes would be a nice feature, but I don't like things touching my screen brightness.
Thank you for your information.

Battery

I know I've made a few posts about this in the past, but now I've learned a few things since then.
I know the battery isn't the greatest on the infuse (no rom that I'm using atm..) but would like to get the most juice out of my device that I can. I have root access and currently use the apps "battery calibration" and "no-frills CPU control" which I set my cpu at a relatively low frequency to help keep juice.
My phone is drained throughout my day, even without use. I believe it primarily happens because my data (mobile network) consumes it. I know apps such as "juice defender" are great at reducing idle drainage because it shuts off your network connection while in idle to save battery. However, I have used this application in the past and after a few days of use, it shuts off my mobile connection altogether.
My question is, if I were to use this application again and my mobile network were to malfunction, would I be able to change my apn to regain my network connection? In the past I had to reset my phone to regain connection, which isn't really worth using if that's the only solution.
Or are there any other battery saver apps worth using??
Thanks

A bit more information is needed before a specific course of action can be recommended. How much battery life are you using in an average 24 hour period? Also, what version of Juice Defender(beta, free, plus, ultimate) are you using, and what specific settings are you utilizing. It is a very customizable program after all. You might look into Battery Indicator Pro, which estimates your total remaining battery life based on your level of usage. I would also recommend CPU spy, which, if your device is rooted, will show the percentages that your device is running at various CPU levels.
If you turn off all the locational stuff, turn off 'update my current location' in Navigator, and set your CPU gov to conservative, you might get better battery life. I've not had any lasting luck with any of the battery saving apps. In the end, I decided to buy a couple of Anker batteries from Amazon just in case I have a bad battery day... Also some of the battery saving mods work, but I'm not sure about applying them to ICS and JB ROMS. I haven't tried!
Battery life is what you make of it..
Anything running in the background will drain the battery.. email constantly checking for new messages, twitter, Facebook, GPS, WiFi if no connection is found, etc..
Anything that makes the phone process even while the screen is off is going to kill a battery..
What ROM are you using? Some ROMs have better life than others..
How much are you actually using the phone?
What's the brightness set at?
Have you tried changing the processor and slowed it down?
Lots of information that is missing is helpful..

How about putting a widget on your homescreen to toggle data on/off. Keep it on only when you need it. I go a step further, I use Tasker to automatically turn my data off every time my screen times out (because that means I’m not using it... I can restart my data later with my widget when I need it). Maybe that’s extreme, but I’m not just watching my battery.. I’m managing my limited data plan.
My phone is drained throughout my day, even without use.

It may be that you have wakelocks keeping your phone awake when it’s supposed to sleep. One way to see this is (in GB or above) Settings / About-Phone / Battery Use...then click on the small graph at the top... should expand it to a large graph with traces along the bottom including Awake and Screen On. If you have long periods of time where phone is awake while screen is off, that’s a wakelock problem. A good program to troubleshoot that is Better Battery Stats. If nothing else, follow the instructions in the first post in the BBS thread linked below, and then post a dump to the end of that BBS thread (the developer and a lot of other knowledgeable people follow that thread and will help you interpret results):

Thru use of BBS, I found that Google Maps is one that was keeping mine awake and I think someone else on the forum reported the same. If that program (Maps) is causing problems, you can disable it from auto-starting on boot using Gemini Manager. It will still be available when you need it, just take a few seconds longer to load the first time after boot. Then need to reboot to stop it from causing wakelocks after use (there may be other easier ways, but this works for me).
Another program (Power Tutor) was helpful to me to see programs that were consuming unusual amount of battery although not necessarily thru wakelocks. In my case Dolphin Browser HD was occasionally drawing very high power even when that program was not actively in use.

So how can I stop maps to running in background? only rebooting the device is the only option?or is there any other option?
TIA

Just to provide more details on my previous post (not sure if it's answering your question):
I followed instructions here:
http://forum.xda-developers.com/showpost.php?p=29420959&postcount=7059
In particular, I installed the free program "Gemini Apps Manager". That allows you to stop programs from auto-loading at boot.
So I used the program to stopp Google Maps from auto-loading at boot.
That stopped a large chunk of my wakelocks, as long as I don't manually launch Google Maps.
If I do manually Google Maps, then those wakelocks come back, and to get rid of them I have to reboot.
I don't use Maps that often (only when I go on trips), so it's not a big problem for me to reboot when I'm finished with my trip to help keep my battery use low.
It may also be possible to kill it from the list of applications at Settings/Applications/ManageApplications and killing botht the application and the process...but I'm not sure if it will stay killed that way... haven't tried. I know some applications have hooks that make it hard to get rid of them once they're launched.
But (if you haven't already), I think it's a good idea to use BBS to find out what programs are causing problems on your phone. You may have other apps causing lot bigger problems than Maps. And it certainly may be the case that a program that acts up on one phone can be fine on another phone due to differences in the way the user configures the application settings and the phone settings (along with other possible differences in application version, ROM used, etc etc).

Thanks for your detail explanation. My main question was how can close the app without restarting? i feel my major battery drain is from dolphin browser, befor dolphin i used opera, even that has the same problem. Most of the time, if I dont open dolphin, my phone battery is good, but once I open it, it drains battery. So i am looking for soemthing simple which does, without rebooting the device.
Any way thanks for your help.

battery drain

Hi.. i lost 20% over 5,5 hours in standby mode.. is that normal or something sneaky going on?
Do you have any apps syncing all the time? Some news apps sync every 15 minutes or so.
That seems like a high rate to me. Have you messed with any of the power options on it (made it not go into standby, etc...?)
I barely got that much drain watching a 3 hour movie.

I'd also check email syncing - if you a bunch of accounts that sync very often, it can affect the battery as well.
Also make sure your Bluetooth is turned off.
It happens to me sometimes and it seems like a reboot fixes it.
A reboot does sometimes work. Otherwise also make sure you close out office programs. I've noticed that sometimes runs down battery a little, though not that much. Are you hooked into WiFi, and is the connection where you are reliable?
i uninstalled few apps and rebooted and its okay now.. maybe it was because of Appygeek app.. try it out
Turn off all live tiles (maybe except mail, messaging and people which are useful) and don't allow any lock screen apps to run in the background which you can change via pc settings. This should significantly improve battery life.

[Q] what is sleep state?

As the title asks, what is it? I know that turning off the screen with power button is not sleeping. I believe it is the state when it takes more than a second (lag) to unlock the screen. This means that the phone was in sleep state and I woke it up. But the question remains, that what is it? How and when is it activated? What happens when the phone is sleeping? Effect on battery (I believe it's positive)? The notifications like sms and call? Is only the screen asleep or are the other functions sleeping as well? Final question, Can I activate the sleep mode with the help of an application if it helps save the battery?
Note that I don't want to use battery saver apps because I don't want anything on my phone to stop. I paid for the whole phone, "including" gps, wifi and things like that. Smartphones are for us, we are not for smartphones.

Technically; sleep mode starts the moment the screen is switched off. With the exception of applications which can prevent the phone from fully 'sleeping'. A good and obvious example is the music application which keeps the phone awake in order to play music.
There's really nothing special about sleep mode except that the phone will execute a lot more tasks together but less frequently in order to save power, so you're still able to receive all messages, emails, calls and all notifications (from apps). Applications can also be informed about the change in power state (awake to sleep and sleep to awake) and therefore change the way they behave.
The amount of sleep time the phone gets is dependent on the apps you have installed and the amount of emails, calls and other notifications you get. There isn't a way to enable 'sleep mode' with an application as it would make little difference if your display is on. Your display is the main cause of power consumption, as is true with all smartphones.
Battery Saver apps are dangerous, by killing apps they have a negative impact on the phone. If the application is needed, the phone will restart it and add to the CPU cycles. The same goes with memory freeing apps. GPS/Bluetooth/WiFi are there for when you need them. Keeping them on when they're not needed is a waste of the phone's resources. As the more CPU cycles they use, the more power they consume.

That's a good explanation
I have read about term "deep sleep" while searching for this, but the explanations on the internet are not clear to me. I have understood a part of it, that this state comes when phone is at rest for too long. The phone pauses apps and their processes, except those who are downloading e.g games and only does basic tasks such as incoming communications (message, call etc.) and sync. Again, I could not find answer to when it state/mode starts.
About GPS/Bluetooth/WiFi: I said this because I had seen people talking about how they have to force otherwise unnecessary restrictions on them and thus have to worry too much to save their batteries. This is what I don't like. Technology is made to facilitate people and to make their lives easy, that's what I believe. On the other hand, I always keep bluetooth off because I need it very rarely. Well, you may have other preferences but I have to keep gps on in order to geo tag photos and to make it ready whenever I open maps etc. Wifi according to me is life blood of smartphones. So I can't live without it either.
When I had Nokia 5800 I had to turn off auto rotate because its menu took time to refresh if I turned the phone by mistake. That was the time when I came to know how bad it feels to go through the settings to turn it on when I need it urgently.
