ok so this will happen quite often to me after messing with customizations or just using different apps. I exit apps that stay running correctly (at least ones I know I need to). my ram will fill up, or almost up and then the phone will freeze for a few seconds. when it comes back up I open system panel and close all inactive apps and anything else I feel needs to be closed. this will leave me with 50% or less free.
usually i'm not concerned, but twice now my phone has rebooted due to this. this happened once back in june and now just today. I had navigation up and when I knew where I was going I woke up the phone to exit it, but the phone was frozen. so I put it down and it actually keeps giving me directions. then I heard the start up tone, I didn't bother to look just put the phone in my pocket. a few minutes later it reboots again. again I didn't bother cause I did not need it. when I did need it I found it with no cell or 3g reception and no icons loaded up. reboot the phone manually and all is fine.
I am rooted with the latest fresh rom. but I have only been rooted for 6 days and I have been getting this memory issue the whole time I have owned the phone(release day purchase). including one reboot before rooting.
I keep reading that we should not have to worry about memory and that android takes care of it by closing apps when new apps need the memory. is this really true?
usually I keep it free by using system panel but I forget sometimes. I haven't used task killers as I read mix reviews and I like some things manual anyways.
so, is this normal? am I doing something wrong, or is there a setting I need? do I just need to go get a task killer?
what are the best task killers? and is there any programs I should not kill? or whats the optimal way to set these up?
thanx for any help you can give me
Try using Advanced Task Killer (there's a free version in the Market) and change its security settings to low, then start killing processes you don't need.
While Android is supposed to have good RAM management... Well, as you can see, it's not that great. Generally, if I get under 100MB of RAM available, I tend to go on a killing spree... Of processes.

me too... when I remember .. lol
cool I'll try out ATK
What settings is everyone using to get the most outta there desires hd battery!?
I know it will take at least 4 cycles to get the best outta the battery, but at the moment I can literally see the battery draining, its not good! I lost 30% within an hour and half! :0(
I'm using advanced task manager, and it never seems to kill all running apps straight away when I hit end all!

1. Dont use task killers...it doesnt work with Froyo and it doesnt help...uninstall it.
2. Empty the battery to the 0% and leave it on charge when phone is off all night.
3. Turn it ON and use it untill it die again...then again turn it off and charge it for 3 hourse. Turn it on...its calibrated
4. Use 2G if you dont need 3G
5. Use max 70% of display light
6. Use only must have online update programs
Thats all...I did that on HD2 and I didnt have any problems for all day...and I used it normaly. In stand by it was 1,5% per hour... with mp3 was 10% in 1hour...etc...
Have fun!
How come task killers don't work? How do I stop apps from running in the background now then without a task killer? Won't this kill the battery more??

No it wont...its like using a notebook... if you have notepad, browser, and solitair opened...but not working with them...they will not use your processor and energy...it will only use your RAM memory... And thats the same with android..BUT after some tome (for example 6hours) if you dont use some app...the phone will automaticlly turn the app off. And in any posiblle way you would never use more than 400MB of 765MB RAM ...so memory is not a problem

My first post here on XDA so hi
Now, I'll just correct you a little. Your example was pretty much correct and a nice one, but Android OS doesn't kill tasks when amount X of time has passed. Android kills tasks when it needs more RAM (=when there are too many processes running), it kills the least used process. Android OS usually runs loads of different processes, the cool thing is that they don't consume any battery because they are not actually used. These processes are stored in the phone's RAM memory, whether there is something stored in the RAM or not, the RAM chip uses the same amount of electricty. Thus processes that exist but are not in any applications' use, don't consume battery. Therefore you don't need a task killer, in fact a task killer reduces your battery life because it kills the processes and then the phone has to restart them, and this cycle continues over and over.
So which is the best way to come out of an app? Back button or the home?

Both are as good, it makes no difference.
I have found that turning auto sync off when not essential saves my battery quite a lot. If I need to check something ill refresh that app. Once I'm near a place I could charge ill switch it back on.
Just a suggestion. Try it and see how it goes for you..

How do i turn off 3G and use 2G network? And how do i turn on 3G when i want to use it?
For some reason after a hard reset everything seems to work fine. Sms messages receiving in time (had installed task killer which i think made the problem possible) and all of a sudden 3G and HSDPA is available. So battery life all of a sudden is less to so how do i change this?

You can go to settings/wireless and network/mobile networks/network mode/gsm only
You can also install extended controls widget wich has a widget wich takes you directly to that screen. A direct switch is not available in this ROM.

Welcome on XDA!
Do you have a source esp. regarding this piece?: the cool thing is that they don't consume any battery because they are not actually used.

Thus processes that exist but are not in any applications' use, don't consume battery
Circle battery mod
This is still kinda on topic, but I find it's much easier to get a feel for battery life, or what's using it all up, if you have something that actually gives you values all the time. I have a circle battery mod, but a percent meter or widget is just as good. It's nice to have it in your face, instead of either intuition or constantly going into your settings to look up the value.
Just my two cents!
So even though the debate on the task-killer issue pretty much favours not using one, there are some misbehaving application that stay in memory a long time after use and continually suck CPU power. For these bad boys we need to kill them via a task killer. Just thought we should list these Apps (mostly third party). Let me start off:
- World Newspapers
- Phandroid
- Google Maps

I'd say that it's better to remove such apps completely, as it is mostly a sign that the app is poorly designed. And if an app takes a lot of ram it isn't really an issue as it doesn't drain battery if it just stays idle on the background. You have to remember that the phone doesn't need free ram to function, like a pc for example. The best thing to do is to get watchdog or similar to monitor cpu draining apps as they are the ones draining battery.

Google maps is an essential app so why remove it? I also experience this, google maps really does drain my battery. I do not open it but it just keeps draining my battery.

I didn't mean any exact app, and no you shouldn't remove maps. But it implies that there's something wrong with the app if it keeps using much. In maps case it could be that gps has remained active although the app isn't running etc. In your case there is something wrong somewhere as it shouldn't be draining battery while off, I and many others use it on a daily basis and don't have any problems. My previous comment was meant to be taken on a general level

I see your point Well, I just checked my GPS and it was offed so I really don't know why it keeps running and it's keeping my phone from sleeping, I solved it before by just force stopping it but I know it just keeps running and draining my batteries. Really weird.
Hi guys, I know that some people say to disable location services and/or GPS because they drain the battery (under Android system in battery usage). I just want to clarify. I came from an iPhone, and on the iPhone I leave location and GPS on, but as long as the app is closed, the GPS will NOT run (just that its functionality remain on) so there is no drain.
Is this the same on Android? Is it okay to leave them on but not run any location-based apps?
Bump...
It'll constantly bounce the GPS signal AFAIK, so will use it up. buuuut, on 4.4.2, you can edit your location preferences GPS accuracy etc and it tells you battery use on it. However I believe it's on perma unless you disable it totally
I wouldn't be so sure. I have GPS, WIFI, BT and all other crap 24/7 and I loose about 3% charge over about 7hrs sleep, personally I don't think it's worth bothering or lifting my finger to shut it off. Also when I drive I see my correct location on the map, after screen goes off and I need to check again few min later, the map shows my last location and it takes few seconds to update to new one. If it was working with screen off it should have been updated right away, no? At least it's working in some low power mode. I think what really kills the battery is all those push services like e-mail etc, especially when not set properly, but the best way is to test yourself.

Technically 100% the same.
However for practical reasons things are not quite the same - as long as you have many, many apps and your data (WiFi and/or Mobile) active certain apps will try to connect from time-to-time, and some will try to get a location. Unfortunately Google Services is one of those, and an older version of that was generating a really huge amount of power consumption. The problem is reported to be a lot better now but I can not confirm since I am anyway keeping my data connections OFF for most of the time when I am not really using those.

I guess this is one of the few things that iOS is better than Android at - managing how apps run. I use Greenify to freeze inactive apps, but the limitation is that I will not receive push notifications. On iOS apps are frozen yet push notifications are functional (that's ironically the downside of iOS too - no true multitasking). I don't disable my data connections because I want my push notifications, but I do turn off GPS. :/

Well, when coming from a situation when there was absolutely no multitasking at all (and that was successfully sold as a "feature" for quite some time) I can really see that being easier

I think the latest Greenify PRO version has something to improve that too. But I will have to test a lot more to see the real limits of that.

1. Reboot daily, and do it when the phone is fully charged AND STILL ON THE CHARGER! Let it sit on the charger for a good five minutes so it goes through the whole boot process without taking any battery usage.
2. find the best (lowest) screen brightness you can live with and set that as your fixed screen brightness. Using Auto-brightness is NOT a good battery saver.
3. Active Apps Manager. I also put this right on the front screen. It's a little number inside a circle. The number is for how many apps are currently running in your phone's memory. The circle around the number turns colors from green to orange to red. If it's red then at least one of your running apps is using the cpu and therefore battery. If it's green then the apps are idle and not using much battery. You can press the button and it will show you what apps are open and what percentage of cpu is being used.
This little widget is invaluable in telling you which apps are notorious for using the cpu (and battery) even though you are not actively using them. It helps you understand which apps you need to kill off each time you use them. For instance I have found that almost all my news apps that have notifications activated will continued to run and eat battery. Also, my chess app, Chess.com. So now I just know to kill them off after I'm done using them.
4. Turn off wifi, bluetooth, gps, 4G, syncing and don't use any live wallpapers.
5. Enable Developer Options and check 'disable hardware overlays' and then 'enable MSAA' (automatically turned off on reboot)
Whats the point in having WiFi, Bluetooth, 4G if you're suggesting to turn it off?? Might want to think that part over again buddy lol
