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.

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

Extreme battery drain: any way to determine what's causing it?

The last couple of days my battery has been draining ridiculously fast. It just went from 50% to 8%, just sitting in my pocket without otherwise being used, in the last 3 hours. Here's what the battery usage displays:
while unplugged for 3h 3m 24s:
Android OS 81%
Cell standby 10%
Phone idle 4%
Display 3%
Android System 2%
Obviously something is going on with Android OS and I suspect something I've installed is doing this. I have Watchdog installed but it hasn't given me any warnings. Is there some way to determine exactly what is causing the battery drain, other than removing apps one by one?
Thanks!

I've suspected that my display keeps coming on when my phone is in my pocket.
Both the power button, and the trackpad turn on the backlight for 15 seconds when pushed, and it's very easy to do both when the phone is in your pocket.

I stopped using the HTC weather app, there is no way to stop it from constantly searching your location and it kills the battery FAST if you are on the move. Since I stopped using it I have seen 10+ hours of battery life a day and I use it hard, internet, gps, music, twitter.

It's the suspend process.
I can't link it to you cause I'm on the phone but if you look around, you'll be able to find it.

I don't think it's the display because the battery usage isn't showing the display as the main battery usage (unless I'm really using it for a long time). It's definitely something belonging to "Android OS". I wish there was a way to determine specifically what process within "android OS" is to blame. I really don't know much about Android or Linux in general so "android OS" is mostly a mystery to me.
I did uninstall several programs yesterday night and was almost convinced it was behaving better but it looks like after the first hour that Android OS is creeping up and overtaking the battery usage and the battery is draining pretty fast despite not using the phone other than to occasionally check the battery usage. At the current rate I'd be lucky if the phone isn't dead before the end of my workday. It probably doesn't help that I have a rather weak signal at work but if it was increased power to the cellular radio that was the culprit, would it show up under "Android OS" or "Cell standby"? I'd suspect the latter, but maybe Android isn't so logical in how it groups processes....
I'll try removing the HTC weather widgets as suggested and look up the sleep process.
Thanks!

It is the "suspend process" like that other poster said. Here is the defect, you can read through if you like. It's a known problem and not only isolated to mt4g
http://code.google.com/p/android/issues/detail?id=11126

How did people determine it's the "suspend" process? I can't seem to find any way to determine what processes are specifically involved. Is there an app that will tell you that? I am running Watchdog Lite set to alert me at 50% cpu and have never got an alert which makes me question whether my issue is the same one described in that thread. Various people were describing 100% cpu activity by the suspend process and it doesn't seem to be the case with me.
I did have 2 weather widgets on my home screen. I deleted both and since then the problem appears to have gone away. I'll have to wait a while to see if it's truly fixed or just a coincidence. Someone in the suspend thread did mention that plugging into a charger temporarily fixed the issue and I did charge the phone for a while after deleting the widgets so I'm not convinced just yet.
One thing I did notice in the battery usage is that google maps seems to have a significant presence, despite the fact that I haven't used maps at all since last unplugging the phone. What is maps doing in the background? I wonder if it's trying to determine my location and cache map data...
Thanks!

Install Watchdog and in its settings, include, monitor, and display all phone processes.

Enable system process and set thrashold to 30% and you will see the suspend process. Or when you notice the drain is happening go to the phone hidden menu. You know the #*#*3626*#*# in the dialer and then from there go to battery usage then select CPU usage, you will see the suspend process on the top or near the top.

Just use some memory management apps. I currently use ES task manager and in advanced settings, i set it to kill all processes when i power down screen. I never use any battery when phone is unplugged(i literally left my phone unplugged overnight midnight to about 7am and it stood at 73% entire time). And having it rooted, i use SetCPU and set the phone at around 768mhz powersave when i'm not messing with the phone heavily. I easily can squeeze about a day and a half out of the battery.

sorry, that was not the correct sequence at all. I was trying to do it by memory. It is *#*#4636#*#* then select battery history, in the first dropdown box select cpu usage. That menu is pretty useful for other things to like network usage breakdown per app, gps usage, etc.

Actually I have removed the HTC weather widget couple of days ago and also disabled the water sync in account settings too. That seems to have help with the suspend process on my phone also.

What's the "water" sync? Is that a swype typo for "weather" sync? (Swype errors are annoying in that their usually not so obvious.)
I had also disabled the weather sync (forgot to mention it). Seems to be a lot of little bugs in Sense that need to get fixed.

Why don't you guys do what I did... I have profiles set on setCPU so that when the screen is off the phone runs at 368mhz max and the when the screen is on it'll go up to opp speed... That actually saves alot of battery for me.
Sent from my HTC Glacier using XDA App

Sorry it is weather sync. Yeah keyboard error. I stopped using swype recently for this very reason, but touch input isnt perfect either but still much better for me.

Ya if you are using OC based kernel then use SetCPU to scale your mCPU. Set few profiles for example my max is 1.7ghz, avg is 1.2ghz, min is 768mhz, idle is 368mhz.

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!

This is excellent, many thanks. As a converted WM 6.5 user I have to say, I am enjoying android considerably more and I prefer it to the Metro interface of WP7. It's nice to know the little tricks to get the most out of it. Thanks again. ^_^

Thanks
Thanks for the info, and for sharing, i will try the different methods

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.

Very good info thanks

You had me impressed until you mentioned task killers. Absolutely horrible...

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.

Install better battery starts and check your wakelocks. Seeing is keeping your phone awake.
In the mean while post a screenshot of your battery usage

if you're using 3g and your phone is losing signal then thats why. low signal strength will kill your battery as it constantly tries to find a new stronger cell and has to keep disconnecting switching to 2g then back to 3g etc. turn your wifi back on it uses less power than 3g

Try es task manager to stop stuff loading on boot as well. Used it on my ds and on the wife's sensation xe. Wife was getting big battery drain, would last a day after ics update, now it lasts 2

Task Killer Misconceptions
So we’ve explained how android works, what it means by “running” apps, and how it automatically manages its own memory so you can stick to enjoying your phone, lets move onto dispelling some common misconceptions about android and the use of task killers:
“Task killers make my battery last longer” – FALSE!
Task killers actually do the opposite, they make your battery life shorter! Lets look at what exactly you are doing when you kill a task. You are completely removing it from memory. Ok, so compared to leaving it in memory you are expecting to save battery? No, whether or not that bit of memory is used by an app or is free, the same amount of battery is going to be used. You are actually reducing battery life because when you next go to use that app, you have to fully reopen it, this uses more memory than simply bringing it out of memory.
“Task killers make my phone run faster” – FALSE
Task killers cause your phone to become unstable and jerky. Killing processes is bad because a process may be shared between applications. When you kill it, you are causing disruption within the OS, forcing apps to reopen, to reopen a shared process.
“There is no exit button, thats why i use a task killer” – FALSE
There is no exit button because android was designed to never have the need for a user to close apps. If an app needs closing, android will do this itself.

@up you're right. But PCrepair was talking about a task manager to prevent some apps from starting at device boot. That's something different. Your really long quoted post was a little bit unnecessary..
Sent by my fingers to your head.

I don't agree with you. I am a fan of ES apps but Es Task Manager mainly purpouse is to kill tasks.
I don't know what's causing the OP's problem but i am 99% sure that a task manager/killer is not the solution.
And please try not to comment my posts context/quallity i don't want to start a flame but i am sure you are not proude of more than 30% of your posts.

@uq the reason for the es app is to stop none essential apps starting on boot. I agree that task killers will drain battery quicker.

Try the OLED Mode on this launcher to save battery

Try activating the OLED mode on this app. Should give you a battery life of over 12 hours after battery low:
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.
Please post in features that you might like to have on the app.

not a bad idea.
can the alert at 15% be turned off?
I'd use tasker / secure settings to make this change on my own at a lower battery percentage

Couldn't this be done with Tasker?

And from the screen shots, it will not save you any power. Amoled only save power when they display BLACK, not greys. I don't want to get into the science, but only complete black saves power, like the status and navigation bar. Don't bother with this app, because it will not save you power, and it kills tasks. Killing tasks is bad in Android. Just avoid this app and similar apps.

The app has an OLED mode and it turns the display black. You need to try before commenting. Just let me know if you have any issues.

You are right and I should have tried before commenting. But my second point still stands. Killing services in android does not save battery, processing power, time, space, ram, anything. If anything, it uses more power restarting essential services. Android is based on Linux, and Linux is the best operating system for managing ram. It does not need any third party apps to help it. Killing processes in android is only bad. It was bad in froyo and eclair when we saw the huge influx of "task killers" on the market. If anything, it is worse on JB and KK, because the ram management has only improved. You would get a much more tangible benefit by installing greenify and greenifying your apps. This actually fixes badly coded apps rather than killing them. Killing tasks just aggravates the problem more.
Other than that, it looks like a nice app. It seems to do what it was made to do. I personally will not be using it because I would rather fix the problems with my battery life rather than stretch to the next outlet, but the concept is sound. Please note that the market screenshots are very badly done. In apps that have a setting to change the entire UI of the app should definitely have screenshots of all or most styles. Screenshots are the first impression a user has of your app, and first impressions should always be good. As a very "technological" user, I understand that I am a minority in your userbase, but it is not good or fair to exclude any parts of a group when it would be very simple to include them.
