The app Clean Master claims it can extend battery life and device performance by killing apps--even offering a button to kill all apps. I thought killing apps was unnecessary since Android does this automatically when RAM is full and that killing apps manually actually drains battery life. What's the deal? Is swiping an app away from the Recent Apps List the same as killing an app? I currently do this often because the list is usually packed.
Thanks.
Clean Master actually does increase performance of your device, especially and lower end ones that have 512mb of ram to work with. However, this also decreases battery life by very little. Android does kill task automatically however as you said it waits until the memory is full which leads to a lot of lag and sluggishness. Swiping an app from the recent apps I believe does kill it. Personally instead of swiping my ROM supports "hardware back to kill" in which I hold down my back button to kill the app. It seemed to do a much better job than swiping.

So Clean Master does "decrease battery life by very little" and the claim that it saves battery life through killing apps is incorrect? This is at the expense of increased performance only if RAM is full, too. It seems that the term "killing apps" is very misleading even for Android users as it actually uses more battery life to kill the apps rather than leave them alone (because they use little to no resources in the background). If this is truly the case, then I guess I shouldn't worry too much about killing apps until my RAM is full and I experience lag. Still, I find it kind of surprising that such a highly rated and popular app claims one thing and does the other.
On a semi-unrelated note, is there some mod I can install on top of a ROM I'm using that lets me kill an app or display the Recent Apps List by long-pressing menu/back button? Or must I install a ROM that has this built-in feature?
Thanks.

Any task killing app such as auto memory manager, clean master, and so on decreases battery life, because it always using background resources. However, you most likely will never notice the difference in battery life lost since it is so negligible. I'm honestly not sure. I did a little bit of research and it usually pointed to that this function had to be in the framrwork of the rom. So my guess is you'd either have to modify the existing framework of a stock rom or just download a rom like Cyangonmod.

Ok so I did the battery boost thing on one of the threads, which says that you only lose 0-1 % per 9 hours on CM 6.1.3 by wolfbreak
When I did that true to its claims it gave me that long battery life but now I see that my battery is draining quickly again
did this happen to anyone else before?

this may not work on others. its just posted to share. its not 100% that ur battery will improve. re-flash the rom n dun try the thing again...or u can try again...if u wan.
Have you installed something after those ''tweaks'' that stays open in the background?
Just some games but no major programs
probably the autokiller settings are too aggressive, and because your apps (widgets maybe?) are being killed and trying to reopen constantly this is actually in effect draining your battery

Some games caused for me battery drain. So try looking with some kind of app (don't know name anymore) which one uses the most battery when on background.

Apps won't reopen if you do nothing and closed them. So it will not cause battery drain. (And if they open without using them it maybe because it sheduled or you pressed a app that made it open)

yes they will.....
Say if you have a calendar widget or beautiful widgets, etc...
Or apps that are set to be persistent
With aggressive autokiller settings, these maybe being closed and constantly reopening

In theory yes. But in most cases the oom value of most commonly used widgets and their neccessary services are not raised or remain at around 0. AutoKiller is actually very intuitive with what apps priorities are raised it doesnt just kill everything indisciminately like most autokill task managers. I have used high values (150,200,250) for AutoKiller for more than 4 months and I have never had it kill any services or apps for widgets or even anything I want running in the background like Lookout, JuiceDefender, EasyFilter or DSP Manager. I also have numerous widgets and have never had problems with any of them being killed. I also get pretty awesome battery life. Chances are the problem is with some apps running unchecked in the background and not that apps you want in the background are getting killed.
Remember that everyone has different apps and everyone uses their phone differently so something that works for some people might not work as well for you. There are a lot of different things you can do to improve your battery life but if you try to set a target amount of battery drain (like the 0% in 9 hours) you can only be disappointed. Just use what you think helps you get the best performance for you and be happy for anything that seems to improve.

If I (or anyone for that matter!) help you, dont be afraid to press THANKS!
Do you guys use task manager? Why or why not?
Sometimes yes...not sure if you really need to with this phone. Just a little OCD on my end
Only when some app is making problems, otherwise no
I often run a kill once at bootup, and then after that only if an app seems to be holding wakelocks or eating excessive CPU.
There is no longer any valid reason for using a task manager for memory management purposes, only for killing wakelock/CPU hogs.
I use Autostart to kill a few things that like to start up on boot, then ATK just for killing wakelock/cpu apps as well.
Mainly FB/Engadget like to stay running when I exit them and cause my battery to get eaten away.
I usually push the "clear memory" button.
I do along with Advanced Task Killer. It kind of nice to know less things is running in the background eatting battery...
ahh, thanks for the reply. cause i was wondering if i should have it as a widget (to clear memory faster) or not (save battery).
I use it when apps are misbehaving or my phone is warm. Mostly its the engadget app.. It runs cpu at like 70% when in background for some stupid reason.

It's up to you if you want to put it as a wigget for easy access. I myself don't, because I hate clutter screen. It only take me 5 seconds to navigate to it.
All the time. just to make sure nothing drains my battery and nothing (especially Browser) is not continuously access internet when I outside WiFi.
Rarely. like others I use one to check and kill misbehaving apps.
I freeze or uninstall most unused apps and disable startup on some.

Not really. I use watchdog task manager to keep an eye on things (with a fairly low threshold - 30%), and it does a really good job. I also use Autostarts to stop a few things from starting up at all.
Hi there, I am wondering if killing apps that I don't use will increase battery life or just freeing up some RAM?
If it does increase battery life, any app recommendation? I don't need it to auto kill, I can press it each time the phone boot. I tried some already actually, like Advance Task Killer but some apps labelled green can't be killed? I am not sure, I am new to this.
Thanks
You don't need a task killer at all, in fact it's better NOT to use one.
Also have a look at this post where I wrote a little about this.
Android is designed to kill apps on its own whenever it feels that your RAM is getting full. I used Killer apps and it only made my phone worse!
So its better not to use one
Gents....
In the quest for battery life and RAM enhancements, and the fact that many applications use wake locks to keep themselves active in the RAM.....is there an easy method to identify which apps contain wake locks ?
I can see active apps easy enough, but does that state simply mean a wake lock is present ??
A little info from a dev or two would be much appreciated.......g

Not sure there's an extra easy way... Nonetheless, check out BetterBatteryStats, if you haven't done so already? It does detect Kernel as well as partial Wakelocks. Here's a link that should help: http://forum.xda-developers.com/wiki/Wakelocks
Also, if I remember correctly, you can open your favorite terminal emulator and type:
Su
dumpsys power
Your TE should display any at this point, and if your TE has a zero in the last two lines, there shouldn't be anything you need to worry about.
As far as RAM goes, Android has managed it well since Froyo 2.2, so its not really a concern that's worth your time. Nevertheless, I still find myself manually shutting down apps that I don't want held in RAM with SystemPanel or Taskiller anyway, d'oh! It's a bad habit - OCD problem for me, lol.., due to many years with Windows Mobile. Bottom-line is that Android will end idle app - process tasks as needed without our help, lol... and I'm sure you know that too.
In regard to battery life, here with Saurom 7.1, the display, mobile data, cell use, and cell standby, as well as an add-on ProximityScreenOff Pro app, consume the vast majority of the battery juice. That said, if I set wifi to sleep when the display is off and shut down mobile data, the battery life and deep sleep % increases dramatically.
Hope this helps a little...
Best to all,

You can check "Wakelock Detector" app which is available in Google Play
It has a simple UI which shows detail list of acquired wakelocks per each application
and as you mentioned, it shows active running apps on the top, which might have wakelock present at the moment.
I made a lot of experiments trying to squeeze most of my LG G2 battery & RAM, and finally I reached those results by the below strategy (please note that this will be just strategy/tips, not detailed steps), and on ROOTED STOCK ROM It currently gives me:
Average Screen Off Discharging Speed 0.3-0.5%\hour (so battery needs 200 hours to discharge, or more than a week!)
Average Screen On Discharging Speed Between 10%-20%\hour (no Gaming) (so working hours about 8-7 hours)
Free RAM after full startup 65%.
(I gathered those statistics by setting Tasker to calculate them for me).
Battery Tips:
So to see almost a perfectly horizontal line of your battery discharge during your sleeping, you will need:
Rooted Stock ROM (I tried this on KitKat latest version).
Greenify.
Tasker
Your brain)) and some work.
OK to get most of the battery, do the following:
Remove all LG & Google Bloat ware; search XDA how to do that.
Disable all animations in you Settings-> Accessibility, this will save our battery and make apps faster.
Now all of the work should be done in Tasker, I assume that you already know how to work in this thing, if not search XDA there is a lot of tutorials...
Once your screen is off, do the following in Tasker:
Turn off the following : WIFI, Bluetooth, GPS, Auto Sync.
Greenify all bad behaving apps, after that use tasker to force close many of the bad behaved one (you should experiment with this).
Down Clock your CPU, for some reason my device reboots unless I set Governor to conservative or onDeman, so here we put it on conservative, with CPU clock between 300 and 652 MHz, there is no need to make it lower, because it gives no better battery life, and it makes wake up time longer.
Those steps are enough to make sure that you will lose about 0.5% per hour only! (my CPU needs about 5-10 minutes to enter deepsleep, this means that your battery drain during this time will more than 0.5%)
On screen ON, you need to immediately set back your CPU to onDemand mode, otherwise it will lag, actually I made 3 profiles for CPU, low (during screen of), medium (when screen on), and high (during gaming), so here I set the OnDemand with frequency 300-1190 MHz, and you will not notice any lag with those settings, also you need to set the maximum priority for the Tasker profile that will do this, well actually I made my own Lock Screen by Tasker screen so that tasker will stay foreground app and has best CPU priority, so swapping CPU profiles will be quite fast and you will see no Lag.
Also I set a periodic sync, when screen off each hour my phone wake ups and turning on wifi (or 3G if I’m out) and turning on AutoSync for couple minutes, and then turn all those things again to enter DeepSleep (step 1).
you need to make a good Screen brightness management in Tasker, there is tutorials on line for that.
Finally, during working, I set many specialized profiles for different apps I use a lot, for example, you don't need AutoSync when you are talking by phone, or reading a book, also when reading books, you don't need high CPU frequency, so I lowering it down, all this tweaks needs some work, but anyway you it will give you considerable battery gain, and you will see that the application that you really using a lot are not more than 10 apps.
I would like to note that I tried many ways to optimize this (except trying different ROMs) like playing with application's wake locks, but nothing worked as good as this strategy for me, if you have some more suggestions it will be great.
RAM Tips:
Many of us trying to make our phones customized and more beautiful, but after a lot of tries I found that all those things only making things worse, even for a monster like LG G2: I tried almost 99% of Launchers available on store, and all of them are very bad in scene of resource usage, for example the most beloved Go Launcher, having 200+ apps, and 3 pages of widgets, uses about 150 Mb. of RAM, this is too much, considering that android itself using about 200Mb. in worst scenarios, even the launchers that claims to be very efficient like Lightning & ssLauncher, that is not true, because once you install them, they indeed use too little at the beginning, but once you customize them and will add widgets, objects to them, they will jump up to 100Mb., well this still is better anyway than Go Launcher.
So to be short, the best one in terms of memory usage, is definitely, and without any competition, is Smart Launcher, it seems that it has a unique possibility to draw/load the widgets on demand (you can add them on special pages) and once you go back to main screen, it will free up used memory in minutes, that's really great, because this launcher on average uses only 50Mb. whatever the widgets you use!!
Also I would like to note that most Lock screens are very memory hungry, I tried lot of them, and none of them used less than 40Mb.!! so it almost like a second launcher! even the best of them like widget Locker or C-Locker! that why I made my own by Tasker itself, but note that after designing a scene in Tasker, it will use a lot of memory (70-80Mb.), and for some reason doesn’t free it unless you restart Tasker, and fortunately after that it will use not more than 20-30Mb. even when the scene is visible! so considering other things Tasker is doing, it's pretty low! so I highly recommend this.
Also any programs like recent app's viewers, side bars, screen buttons etc.. are also very memory hungry, I tried a lot and none of them really efficient, don't dream to get one with less of 50Mb. usage! so it's better, in my tests, "on screen buttons" are the best one with about 10-15 Mb. usage in case you don't like the navigation bar as me))
Well those tips allowed me to have very long battery usage, and about 50-60% free RAM, and without animations, makes my phone LG G2 fast like a Hell even with lots of apps installed, hope this was helpful.
Cheers!
Wow...
Nice Tips...could you mind to share your tasker lockscreen?? =)
If you switch off WiFi/data, you loose connectivity..isn't that the point of a phone anyways? Say somebody sent you a message on WhatsApp, you might get it only after 1 hr under your profile, the whole point of the message is lost ..guess that is too heavy a cost to pay for battery..but people are different, so somebody else might have different priorities
