"Don't keep activities" - anybody use it?

Love the phone but a few times the launcher has redrawn after exiting an app because of most likely memory issues. Anybody using this option? Assuming over time this would keep more memory free and reduce this issue. Any thoughts?

This is one of the reasons why I don't like that Google included these developer options pre-installed on this phone. They're developer options for a reason, we can install them if we need to.
This feature is designed so that developers can test their app to be sure that data is properly saved when is no longer in the foreground. For example, if a user receives a phone call or jumps to another app, the app needs to do what is necessary to save it's data. At times, Android can kill a process in the background. If the user plans to go back (perhaps they finished the phone call), they want to see what it is they were working on last. The developer is supposed to handle this case by rebuilding everything as it was before (to provide that seamless experience for the user when switching between apps).
This debug feature helps us test that it works.
For the average user, all you're really more likely to do is slow down your apps. As they will have to rebuild themselves when you resume them, and you may even open yourself to more quirky bugs (for those apps that didn't properly test the above scenario).
So please don't enable it unless you're doing it for development purposes. My 2 cents.
*EDIT* Here's a page from the Android Dev Guide justifying my explanation:
http://developer.android.com/guide/developing/debugging/debugging-devtools.html
Immediately destroy activities
Tells the system to destroy an activity as soon as it is stopped (as if Android had to reclaim memory). This is very useful for testing the onSaveInstanceState(Bundle) / onCreate(android.os.Bundle) code path, which would otherwise be difficult to force. Choosing this option will probably reveal a number of problems in your application due to not saving state. For more information about saving an activity's state, see the Activities document.

(and yes, they used to call it "Immediately destroy activities")

Thanks. I turned it off. Did notice some bugs while on. I just wish with 1GB of RAM the launcher wouldnt have to reload. Hopefully things get better. Might just be my apps but it happens quite often when leaving the browser.

weird.. how many widgets do you have on your launcher? the more widgets you have, the slower the launcher is.
Have you tried another launcher? The stock launcher has never been known for being fast and efficient, although I haven't had any issues with it (whereas I'm a LauncherPro fan on my other devices).

I have quite a few Widgets but nothing too crazy I don't think. I use LauncherPro on my other devices as well but I love this new launcher so I'm going to stick it out. Like I said the most common task that causes the issue is when I'm using the web browser and then come out of it. Otherwise its been stable. I've noticed the same thing with Honeycomb on my Xoom so it might just be one of those things I have to put up with.

i'm also noticing some redraw and occasional lag when hitting the home button.
I'm hoping that CM9's custom launcher will have an option to lock it in memory- that may increase the performance by a lot.
also when replacement launchers like go launcher start optimizing more for ICS those might be good options.

Have you tried converting your launcher into a system app? You'll need to use Titanium Backup Pro or something similar to do it for you, or simple copy the APK into your system/app folder... Really sped up my launcher!

Thanks for clarifying the meaning of "Don't keep activities"

my razr xt910 cannot be counted upon to run smoothly with all the apps simultaneously running and forcing itself to go into reboot. i then fancied an iPhone single styled system (as compared to Android multi-talks) cuz iPhone looks robust and responsive. all the killer that claimed to do the job looked more of a farce and then when i stumbled upon the destroy activity i was like OMG. srsly b4 using it I've only got just inner 100mb of ram, after using it i have a whooping 400mb ram. UI appears faster and all. regarding the relaunching of apps and battery life being used up. i think I'll start to worry about it on a later date. what say any body. ooh yes to add on, even after i deleted 40 apps on my phone it still hanged like fcuked. i guess i can reinstall them back again and not have to worry about it. btw i can't seem to root my xt910 for nuts so i can't custom ROM it along with all other fanciful mods that i hear about what others did to their phones.

Best power saving method I found was a MUGEN 6400mAh extended battery, why get a phone like this then turn off all the good stuff.
If power is a REAL issue consider the MUGEN, dont go for one if the cheap backs, I brought one wast of money.
The standard battery should give you a day easy, have mine overclocked to 1.8ghz always gave me a good full day on standard battery.
If you really wants to save power the way do it is this.
1. Stop unnecessary widgets from running
2. Stop unecesary services
3. No live wallpaper
How -
Download Autostarts from the play store, this program allows you to do all if the above.
This usually saves more battery power than anything else. WHY HAVE TWENTY SERVICES RUNNING WHEN YOU ONLY NEED 1 WIDGET.
Be careful as this program is powerful and with power come responsibility.
RED OR BLUE YOU CHOOSE !!!

Yes, me too. Users in Google Play will just download and use it, but here we like to know EVERYTHING!!! lol!

You'll have to give waaaay more info. A "turn me on/off" button and a pic of Mila Jovovich holding a gun won't cut it
And I mean not only here, people that find your app through the Play Store probably won't get interested in installing it due to the lack of information given. It will come across as rather shady to most people tbh
Give the people more info and your app might have a chance of making it!

Hahahaha
The app will turn off mobile data, started a few minutes after screen off. and then try to enable data, in incremental delays.
At night (started 0am), data won't be enabled again until 6am.
If you turn on screen, data will be enabled again.
Snapdragon battery guru: not compatible
Using my app, network location is not required
Greenify: compatible

Are there any plans to add wifi management as well? That would make it a keeper for me perhaps since i dont really get data where i am located. Just lousy E lol

I think wifi management is better in 4.2, and suck less battery even when connected.
But maybe.. I will add wifi management later

[APP] [Launcher] Death Mode Battery Saver

The app link on the playstore is https://play.google.com/store/apps/details?id=com.webzler.soslauncher
Description
This is a homescreen replacement that has an Ultra Power Saving Mode for your phone to help you extend battery life when you are running out of charge. This launcher allows up-to 4 apps on the home-screen.
What this app does:
1. Kills all running apps and services.
2. Disables WiFi, Data.
3. Shows Missed Calls and Missed Messages.
Ultra Power Saving Mode:
4. OLED Mode for AMOLED devices.
5. Changes governor to Powersave mode. (requires ROOT Access)
6. Disables 2 cores of a Quad core phone. (requires ROOT Access)
7. Reboot during exit. (requires ROOT Access)
When your phone goes below 15% battery, the app shows alert to clear the defaults for your current launcher. After clearing, set SOS Launcher as the default homescreen, and the app would take care of the battery. Once you quit the app, it would clear itself as the default launcher and you can start using your favorite launcher back.

What services does it kill?
Killing certain services will only create a wakelock for apps that request certain cervices.
Killing all apps? Like a task manager?
Well task managers have been kind of debunked for a while and killing all running apps only consumes more battery since most will start right back up.
Oled mode is useless for LCD/IPS screens.
While your work is appreciated a kernel tweak is all that's needed to save battery and most "battery saving mode" apps on android are useless.

[Q] My samsung galaxy tab 3 is soooooo slow

I just got good deal on samsung galaxy tab3. I paid only £69 for a new one, before I had HTC Flyer which my children killed after few years of using. I expected technology moved forward and samsung to be decent manufacturer however to my surprise this tablet is extremely slow. Way slower then my grandpa HTC Flyer ever was!
It is lagging so much that it takes to press it sometimes 7 times for a video to go to full screen not to mention anything else. On top of that sometimes it does turn itself off!!!
So what is a reason fro that and what should I do. Should I send it back get refund and add few extra £ for Nexus 7 (I got nexus 4 phone I am delighted with performance and smoothness and with most of it's aspects), or should I root it and get custom rom (but then warranty is not an option). Is it typical for those tablets or do I have faulty one?

Sounds like a bad build. Exchange for another

All tablets and phones are slow compared to computers. Remove the 2000 active widgets and 300 apps you loaded and try it clean.

hi,
i have a t210r.
svelte 4.1 runs nice.
ditch all the superfluous stuff - do not mess with fusedlocation.apk.
then build it back up with better quality more sensible apps.
use sdmaid to clean it good every once in a while.
use rom toolbox or systemcleanup to kill snoopy and pointless recievers and auto starts.
sslauncher is a lot nicer than nova [no go]
and appcache cleaner widget on the desktop is a good thing.
for a low end tab it really isn't that bad.
nexus 7 sucks for one major reason, no sdcard slot.
i'm telling you, the cloud could go skynet any time
for play you only need play,login service, and services framework apks
oh, and chrome [the swirly rainbow one] is awful.
use the stock stock browser, firefox seems to do okay
and i absolutely love mxplayer.
bye

Hi
This device have just a dual core CPU 1.2 GHz!! and you must not attend very responsive performance on this device with android 4.1.
But I offer you factory reset or a suitable custom ROM.
Totally,you shouldn't compare a mid-range tab like this to another(already systems were very incomplex than now as performance was better and more responsive)
