Hi Guys,
I saw this on a foreign website. Not sure if this has been posted already.

This will turn on power management for the above protocols. Logically, it should save us some power. The orginal poster claims that there is a significant increment in his battery life .
I've applied this tweak to my SPV M3100, Hopefully this will save me more battery life.
N.B. please do a backup before applying this reg tweak just to be on the safe side.
Update: been using it for the few days and I must say I've noticed some improvement in Battery life. no other issues at the moment so far so good
What exactly are the above protocols? L2tp1, pptp1... what are those for? its not like that nokia tweak where it gives less power to the antenna?
Basicly is this tweak gonna cripple my device in any way?

The above mentioned protocols are used for VPN (Virtual Prvate Network).

I've made those registry changes to my TyTn. So far, I can find no bad side-effects.

Hmmm... Well, so far I think the battery life is a little better. But I need more time to really test it.
(Now that I've installed the Battery Status plugin, I can see the power usage, so I'll fiddle with these settings and see what happens to the numbers.)

Thanks for posting.. but Like most random registry tweaks, I'd suggest not touching them for the following reasons:
They are not in the associated MSDN documentation for the reg keys. This is usually MS's way of saying 'this doesn't work right so we don't talk about it so no one thinks we support it'.
Second, the protocols it refers to are all network protocols that aren't generally in use by most people anyway and those that do wouldn't have vpn's running 24/7 therefore any power savings would be minimal.
Thirdly, they were purposely disabled for some reason. I assume because there is a problem with them. And my device is unstable enough
Just my 0.02c
FYI: My test results
In my admittedly objected tests (I changed those settings, soft-rebooted, and then watched the batter drain number for a few minutes), it looked as though enabling the power management for those 4 settings brought the batter drain down a little faster then with them disabled. When they were disabled, it took several minutes for the battery drain to drop down to about 90mA. When they were enabled, the batter drain dropped down to 90mA within about 2 minutes. However, in both cases, the battery drain seemed to bottom out at about 88mA after a while (actually, right after the backlight went into power-saving mode). So I can't say these settings would save a "significant" about of power. YMMV.

If it's not supported, I can understand it. But, I've found with my Wizard, and now my Hermes, that just because it's disabled, doesn't mean it isn't useable. I've found a variety of registry keys that I love tinkering with. That isn't one of them thankfully, but some of the things that they disable there aren't any problems that I've seen, so therefore I add them back in.
A good example is that "Wireless" today plug in. Sure, it really doesn't server a whole lot of purpose, but I like it, so I put it back in.
Much of it is in the eye of the beholder. N00bs probably shouldn't do some of this stuff. Then again, if it weren't for our curiousity, we'd never make any progress hacking these devices...

This wouldnt be the right forum if noone would investigate any kind of improvement (or at least finding out if it does anything, positive or negative)
I we would go for what MS suggests or covers in their docs, we wouldnt flash roms, apply MUIs or anything in that regard.
After all this site is called XDA-Developers and playing around with tools, tweaks and sharing knowledge is what this is about.
So far i cannot see any change in battery life. I will give it a few more test.
if there is a way that we could scale the processor based on the processing requirements, then we will always consume optimal power... something similar to speed-step intel has on PC's.
from what I know for this to be possible, the CPU has to have dynamic voltage scaling, meaning that when the processing load is reduced, the core voltage of the cpu reduces yielding reduced clock frequency. when more isntructions need be executed, the voltage supply to the CPU core will increase, hence increasing clock frequency.
has anyone read the documentation in regards to the architecture of the samsung CPU? if it supports dynamic voltages scaling, and if it is wired up to a dynamic voltage source, then there could be some tweak to enable such a feature.
I've had the pleasure of reading the Samsung CPU manual. You should too!
It doesn't support much clock speed scaling - ie you can't easily overclock (and even then, not by anything of signficance). Voltage scaling is possible. Look into Pocket Hack Master.

if the core CPU voltage can be scaled, then we instantly have a scaled clock frequency. there is a direct relationship between power dissipation in CMOS semiconductors, clock frequency, supply voltage, capacitance and probability if switching (ie dynamic clocking).
Here is an interesting read for you softeare hackers out there. it is a project ot implement dynamic voltage scaling on pda's for those that have CPU with fine grian dynamic voltage scaling. the work is on linux os on a pda, but the methodology should be the same.
http://www.eecg.toronto.edu/~tamda/csc2228/
Dynamic voltage scaling doesnt imply that we can overclock the device, but instead keep the CPU running at a speed that is ample for the processing that it is doing, ie, dynamic. so if there are no apps runing besides an idle today screen, why keep the CPU at 400MHZ running at its full voltage supply. lets reduce it to an amount that it enought to handle the performance requirements of having an idle today screen BY reducing the supply voltage.
Dynamic voltage scaling is basically an algorith (if the hardwre is there) that can be implemented at the CPU level or OS level to monitor instructions required per second etc, then adjusts the CPU core suply voltage accordingly. So in effect, we can get our devices running from 10MHz (doing nothing and consuming little power - I am sure this is the case 70% of the time) to 400MHZ (running apps, GPS, video streaming etc - and consume more power)
I have a PhD student doing his thesis on dynamic voltage scaling for mobile medical devices and the philosophy is "do (process) only what you have to do (process)"
EDIT: Just looked into pocket hack master, it does some kind of clock scaling, well, I learn new things everyday, this is my first PPC and its overwhelming.
vijay,
what is the model number of the samsung CPU in the hermes? i cant seem ti find it?
EDIT: I found it, Samsung K5D5657ACA-D090, it seems voltage scaling is not supported by pocket hack master, that app supports the samsung ric micr S3C24XX series in which the S3C24A0 has a max clock of 200MHz running of a 1.2V supply
also you may want to be careful with Pocket Hack Master.. some people have reported it completely bricking their device. I had it installed it hours before my phone died, but i dont know if it was the cause due to a high amount of irregular bad blocks that werent there when i got the phone.

I dont trust it, it doesnt support our samsung CPU in terms of voltage scaling and by simply scaling the processor frequency isnt really going to accomplish much of an energy saving in terms of the big picture. by big picture i mean with respect to LCD screen energy consumption, GSM radio and UMTS radios (all of which use separate LNA's for each of the Centre Frequency bands) BT etc....
This trick, run on wm 6.5 ?
Can you post your usage and your battery life ?
Just as DUKE09 posted in the past in the Elf forum, I'm reporting the information needed to understand our usage:
- Things that you made with touch (gaming, video,gsm, music etc.) + how long? (hour plz)
- Whether if you switch off your touch at nights or not?
- Fully discharge and charge ?
- Total time to reach at zero level ? (touch turns itself off)
- Settings for HKLM\System\CurrentControlSet\Control\Power\State\Resuming\{98C5250D-C29A-4985-AE5F-AFE5367E5006}\Default
HKLM\System\CurrentControlSet\Control\Power\State\Suspend\{98C5250D-C29A-4985-AE5F-AFE5367E5006}\Default
HKLM\System\CurrentControlSet\Control\Power\State\Unattended\{98C5250D-C29A-4985-AE5F-AFE5367E5006}\Default
- Background applications
- Band (GSM or 3g)
- BT ON or Off
Mine are:
- No gaming no video or media, 1h30min phone call per day, 5 sms, plus Active sync via BT
- Charged during the night
- No full Discharge
- Dunno when it will be completly discharged (i need it for work)
- Registry settings all three configured with Default = 3 (my BT headset never disconnects even if the dual is in standby), I've played a little bit with those parameters and i found that with Default = 4 my battery drains really fast.
- Sometimes I use PocketCM and FullScreenKeyboard, both in background
- Disabled 3g, via Band menu in the Phone Settings (setting Band to GSM) and HKLM\Software\OEM\UMTS\OpMode configured to 1.
- BT always on
With those settings at the end of the day my Dual is at 60-65%
Please post your comments here !
Thanks in advance,
Raid.
You certainly doing better then me! my Dual at the end of a working day is at measly 30-40% but then again I do have it on set 3g all day, listen to about 90 min of music via bluetooth headset and surf the web for about an hour as have unlimited data plan with 3
Hhmmm!!! I going to try your power management reg tweak, I'll let you know if it makes any difference, if does nice find Raid!!
Fully charge in the morning, turn on Bluetooth 24 hours, MSN for 2 hours using 3.5G, Web browsing using 3.5G half an hour, talk on phone average of 15 mins at the end of date left 30 percent.
@gfreek
I think that the default setting is "3" for all power parameters.
I've modified those to "4" due to random disconnects of my old Nokia BT Headset (maybe is not compatible). But then I've found that the problem was the BT headset and not the Dual, and I've switched back to "3" due to an heavy battery drain. I dunno if your ROM has "3" by default.
Looking at the first two posts I think that using the Dual in a "normal way" for that kind of device, we have to charge it at the end of the day....no chances...
Has the Touch Elf a better battery life ?
Regards,
Raid.
I have Qtek 8500, Qtek S200, HTC 710, HTC Touch Dual ... all Device have simulare batterie drain!! I think ... HTC Touch Elf too. Only resone why i think Touch Elf is in the moment batterie friendlyer ... you can install a CPU Scaler to save your batterie. I use all Device in the always online mode (need Exchange Sync or Blackberry ... both are simulare in Batterie drain!)
Hi raid, I can confirm my dual default for all three was set to 4, I've now set it 3 like yours, let see if makes a difference on mine.

Ok gfreek ! I'm waiting for the results !
ok raid here's my findings with this tweak:
BEFORE:
Battery Level after a working day = 30-40%
(based on the below settings/usage)
AFTER:
Battery Level after a working day = 50-55%
(based on the below settings/usage)
Settings/Usage:
Band - 3G
Web - 1 hour day
Music via BT Headsets - 90min
Calls - about 20-30min
So as you can see raid this little reg tweak does have an overall effect on battery level! Just curious raid did you try setting yours to 2 or 1 on these registry? did they any more difference? or should I just stick to 3.
those registry settings, what are they doing?!
Did you guys notice any instability afterwards?
I didn't try to set them to 1 or 2.
Referring to this post http://forum.xda-developers.com/showthread.php?t=273990&highlight=keep+wifi+standby+bluetooth+Power
I think that with 1 or 2 we get more power consumption...
The strange thing is that with "4" BT should be off during the standby, instead we just get battery drains faster !!
Maybe the power states are different on the Dual ?
Many thanks gfreek !!
Please, if any other can confirm what we have tested, it will be much appreciated...
Settings work for me. Went from 25% left end of day to 60% left.
Also this helps: http://forum.xda-developers.com/showthread.php?t=305332
Anyone more tips ?
Admins, I think this thread should be a sticky !!!
Please ANY DUAL OWNER, try those power registry settings !!!
Just to have more feedbacks....
Many thanks to gfreek and steven !
Another Reg tweak to increase battery life even further!!
Hi guys I have tested this and found a nice little increase in battery life on top of the reg tweak Raid posted here! You're likely get 10-15% increase on battery life with this tweak, it may not seem like much but a power user like me, it does make a difference
With the combination of these reg tweaks settings at the end of a working day my Dual is at 65%-70% before it was 30% - 40%
Settings/Usage:
Band - 3G
Web - 1 hour day
Music via BT Headsets - 90min
Calls - about 20-30min

Do you know what is PPTP or L2TP???
Why you think, it can helps to save Power?
PPTP and L2TP is a Tunneling Protokol! You only need them, if you open a VPN Tunnel to a Privat Network. If you change settings and you doesnt use the buildin VPN functions, you will save what??? Nothing ... yes ... nothing is the only right answer!
If some guys want realy check his power consuming ... please use a Amp Meter and a Datalocker for long time messurments!
Next ... if some guys change here Radio Rom ... possible they save Power! What Radio Version was in his Dual???
This are importent questions!
Sorry for my bad English but this tweaks are pure nonsens!!!

LOL! NetrunnerAT I can see you are very opinionated person! FYI yes I do know what PPTP and L2TP are!!!! what part you don't understand when I said I TESTED these tweaks, in fact tested it over week with and without the reg tweak just to make sure they really did make a difference, I know on paper these tweak should not make a blind bit of difference but they did!! maybe I've got a very special dual MY PRECIOUS!!!!
Realy???
Very Strange ... for Windows CE 5.0 you can buy a Technical Document for the Registry Hives. They are simulare. It say ... if you Open a Tunnel, you can disable the Powermanagement. The reason is easy ... VPN Tunnel need a up and running connection. If your device close it, for saveing power ... the session keys are invalid. New IKE exchange is needed!! A normal Handy doesnt use it!
Italian touch dual:
before:30% at the end of the day
after:40% at the end of the day(i obviously tried the mod for several days to avoid casual alteration due to a different usage of the device)
1hr phone
.5hr web
some casual gaming/mp3/movie
2g/3g auto select, so it eventually switch when there's 3g coverage
usually recharge when batttery approximately goes to 10%
BT always on
now, could anyone kindly explain what these registry mods really do??
i haven't noticed any issue till now.
same for me
i have abt 10% more battery.
i realized, that bluetooth really sucks battery. If I disable bt i have 60-70% left at the end of the day. with bluetooth 30-40%.
butr isn't that a shame? a new battery which I have to charge every day? what do i have to do in 6 month? charge it three times a day?

The BT Settings change the Working Profile of the BT Stack.
I still love my phone but wondered how many people have noticed the same issues as me, I am hoping for a new patch soon to fix these problem, some have been mentioned in other threads but this is my list.
Call volume is too low
Wifi does not awake properly
battery shows 100% usage when in sleep mode
Screen randomley activates while in call causing call to drop due to touch screen being pressed.
Slight Lag when using the dialler, you can hear the DTMF tones later then you press them.
Charging takes over 3 hours, longer using USB.
When on a call people complain of poor call quality, mostly using bluetooth
Videos on youtube etc out of sync
I would imagine these faults are on everyones phone i would be interested in hearing if anyone has any solutions? I am running 1.6
Also note that about 5 of the above issues could be caused by something using my phone when it shouldn't be, but I cannot find the culprit lol

About USB charge, its normal. USB is dont have the same parameters as charger plus as far i remember the USB on the front of a lot of cases dont give the same amount power as the ones at teh back of case. Im not sure how does it look at notebooks.
I didnt had any problems with Youtube, on 3G and on Wifi the videos was playing properly.
I have the same problems.
Battery is down pretty fast and Wifi sometimes looses connection.
Another problem is, that sometimes the phone is loosing connection to a phonecell and has to reconnect. So for a minute my phone isn't online anymore.

Yes i have had total loss of mobile network while driving along, even though I know the area is ok.
I share the following problems
Volume is too low (mainly call and podcats) and even more using bluetooth.
Battery is odwn pretty fast even when i'm doing nothing! But I have the phone for few days and didn't read all of teh tips about battery yet.
In the market app (and some other) I need to touch severel time the touch "search" or "enter" in order to validate, it often doen't work the first time.
I only experience the battery problem for the first few days. after a few full battery cycle. my x10 battery last about 48 hours with moderate WiFi browsing. push gmail and a lot of txting.

I share your issues as well. The most annoying for me is the screen randomly activating during calls. Especially it seems when using the headset (posted this else where so im glad im not the only one). Also people I call complain that I sound echoy.
However, at least we have some confirmed updates coming our way as per the official X10 blog. But Q4?? Seems so far away.

I think you will find that is the screen protector causing the touch issues, it makes it hard to touch in the corners and can be fixed by removing it, although I have kept mine on
I would say most of the problems people are having is phone not going to sleep properly, once this is fixed the phone will be much better.

well what you are seeing is *digital* zoom, it basically using a smaller area of the sensor and enlarged it.
the camera might not be the best, but is much better than most smart phone
my problem with the x10 so far
-timescape not very smooth
-mediascape is pretty bad
-during a call the screen go on and off (even when using bluetooth)

In call volume is really low, but i think that this is software problem
Install advanced task killer and activate auto kill. then you can see really improvement of battery. The problems with battery are because of applications running in the back

I use task killer, that doesn't stop the sleep issue, something is working while the phone is in sleep and keeping the phone awake 100% of the time. i may try formatting the memory card as this seems to help some users.
I disabled the Location thing. the battery improved considerably. i guess it used the cell broadcast function when i had the wifi turned off. and it does that with the screen locked also, but you don't actually need it. so just disabled it.

I have a problem with wifi connection getting lose and switch to 3g while I know that my home wireless is super good and I didn't have problem before rooting...I heard there is a wifi patch somewhere but I couldn't find anything...anybody knows?
for the battery there is a thread here for setCPU software and how to add profiles, specially having the processor operating at less than 300MHz after 30% battery and when the screen is off helped my battery improvement supergreat at least when battery bellow 30% u will be sure that you are squeezing few extra hours just to use it to make phone calls...what I'm saying it did more than doubling the battery life for me worth trying
For wifi problem i might have figured out the problem when u go to setting > wireless control > wifi setting > then hit the bottom left button there is advance setting (that i never noticed before) where u can set wifi to sleep, feel free to set it to never...im gonna c if this gonna fix my problem

Everyone complains about low call volume, but I have never noticed it...the actual speaker, for like speaker phone is definately a little quiet at times though.
To the OP, if it says your phone is awake for a large percentage of the time, and you haven't been using it for that much time, then there's probably some app that's not allowing it to sleep. If you can figure out which one it is, it will increase your battery life.
One problem I've just noticed was that there is no way to create groups with contacts. Certainly not a serious issue, but it makes sending a mass text very annoying.

There have been many reports concerning the long term usage of android and it's effects on WinMO, but, I've read some reports regarding usage of android effecting the device itself, mainly the digitizer, causing it to malfunction, are these reports frequent? and does android truly effect the hardware itself in some way?
Could you link to these reports please......

Not convinced myself.
Would like to see whats got the OP in a panic though........
I do sometimes find that my clock/calendar is altered sometimes after returning from android...... no serious problems though
I fail to see how it could possibly affect the digitiser though..........
I use android for months, my digitizer works just fine. Just be kind to your phone, and android will live long and ever after

Yes thats why I am looking for a back and home navigation bar like iphone, it would be better for our buttons. It doesnt have to be iphone style, as long as it works, i would even want to do the graphics if sb could code it..

I can confirm that using Android will lead to memory issues, energy levels dropping very quickly and conflicts in the processor stack - but only for the human using the phone trying to find a build that does it all!
Seriously though I think the only danger is to WM, not the hardware (unless you overclock) and that comes from booting the kernel. WM shuts down real fast, any ongoing registry writes etc may corrupt so best disable sense and all apps before pushing the Android button.
Like I honestly don't understand it. They are obviously doing something wrong. I am running NAND with the SD card for applications (Stock 16GB) with gauner1986's HD-FI 0.3 with 2.15.50.14 and I have only 2-5ma battery drain on standby. But here's what I noticed:
Certain applications from Market increases battery drainage. If you install an app, begin to experience high battery drain, uninstall it.
It's a 3G phone for godsakes. Why disable the speed of it by going 2G?
Disable WiFi/Bluetooth/GPS when not needed.
Don't disable AutoSync or Background Sync. I've noticed no increase with both of them except when it pushes email, updates
Keep the brightness UP to 100 percent. I saw no difference upon lowering it.
Don't disable APN either. This isn't your dumbphone, it's meant to have internet. Internet won't drain your battery life if it isn't active.
SetCPU is pointless. I don't even touch it as the risk to damage your phone using it is great. There has been no solid evidence this helps your battery life other then to SLOW down your phone.
Don't use a TaskKiller - Common sense, it eats battery. Android is programmed to kill apps.
On standby, it can last for freaking days even under light/medium usage. Constant heavy usage will make you last at-least a day.
Seriously. If you get drain, you have the wrong radio or application. I even tried uninstalling stock applications like Calender and removing widgets and they had no effect on my system. If you have to disable MAIN smartphone features, you might as well go back to:

Personally i think your better off keeping the brightness as low as possible as i did experience battery drain when i had it up to 100%.
I have a taskkiller and I don't notice any difference at all. Having the brightness to 100 does drain your battery that's just common sense.
have no probs with batt drain, i dont use appkillers, brightness on about 45%, play music most of the day, internet on all day with updates, txt and call daily, still on 75% now, not a problem

Because it really is a battery consumer. Actually, surfing on 3G is more power consuming than on WiFi, and Edge is fast enough for a fair amount of uses. Having a 2G/3G toggle widget is probably best, indeed no need to dumb down your phone too much.

WiFi & BT are obviously true, GPS is bullocks. As long as there's no GPS app running (i.e. there's no GPS icon in the status bar), your GPS is not active and is drawing zero current. It's just a setting.

For some people, with certain apps behaving in a certain way (for example business people getting emails every minute), this can really be a serious battery hug.

First part is true, enjoy the features your phone has. It does drain your battery though, even when inactive. There's no such thing as a free meal. Disabling mobile data won't double your battery life, but is a very valid option when you really need your phone to last just that little bit longer.

No need to clock down your CPU to 245Mhz obviously, but a 900Mhz clock speed will still more than suffice for most users.

As other posters have said that is nonsense mate. You can easily see with current widget that the consumption is higher with higher brightness.
Bluetooth battery drain is the only issue
Coming from Windows 6.5 -as we all do- we all discuss the battery drainage.
All reasons for battery drainage given in this thread are true (bright screen sucks battery, 3G does etc etc.).
BUT WHY DOES THIS HD2 on ANDROID SUCK MORE BATTERY THAN THE SAME HD2 ON WINMO?
The bluetooth drivers obviously are not the right ones. On Winmo there was no significantly higher battery drainage with bluetooth on than with bluetooth off.
In all Android Roms that I have tried (and I tried them all), bluetooth empties the battery with about 60mA.
Who knows a rom that does not have this bluetooth problem?

I work outside in direct sunlight, where low settings makes it not viewable. I have it to max and even at home at 40 percent, I see no changes. Probably because of my usage pattern.

Taskkillers have been proven to drain your battery. Google themselves have said it and admitted it in complex details. There's a thread on it that Ill pull up later at home. Like I said I see no differences in my battery report.

So why when I run a task killer I get over a dozen apps running in list and when I close them my free RAM goes up, surley if they are using ram they are using energy?
Also surely the energy that these apps are using is MORE then the energy of the task killer itself?
There is ****loads of apps that just seem to run themselves in background and have no need to, I set my killer to kill every 30 mins or whenever screen is off aswell as manually when I choose to.
Can you provide any evidence that the task killer uses more energy then all the apps running in background combined as I seem to get much better battery with it then without it.

No, just being in RAM memory does not (or maybe very little) use energy. When idle, they're just stored there. A lot of apps simply restart soon after you kill them, consuming a lot more power than just leaving them be, and on top of that you may experience bad app behaviour.
Well, if those apps do stuff they shouldn't be doing, they're badly developed and should be removed or updated, simple as that. Chances are though that those apps really need to be running (and their battery consumption doesn't necessarily have to be high), in which case killing them is even worse.
A lot of well known devs have very clearly pointed this out multiple times (Cyanogen for example is one of them), even Google twittered about it. Do some research, there's plenty of info on it.
It was good to know that info, i never knew that app killers could do more damage and use more power than none at all.

Also incorrect, most applications are killed upon exit/back key hit. Or put into a suspended mode that eats no battery (Android Browser, Facebook etc)

If only that was true. Killing applications will restart them which uses RAM to restart them which can also slow down your system. Applications don't run unless they are continuously fetching/streaming data or providing a service.
Can you provide any evidence that the task killer uses more energy then all the apps running in background combined as I seem to get much better battery with it then without it.

tl;dr version at the bottom.

By default, every application runs in its own Linux process. Android starts the process when any of the application's code needs to be executed, and shuts down the process when it's no longer needed and system resources are required by other applications. A content provider is active only while it's responding to a request from a ContentResolver. And a broadcast receiver is active only while it's responding to a broadcast message. So there's no need to explicitly shut down these components.
Activities, on the other hand, provide the user interface. They're in a long-running conversation with the user and may remain active, even when idle, as long as the conversation continues. Similarly, services may also remain running for a long time. So Android has methods to shut down activities and services in an orderly way:
- An activity can be shut down by calling its finish() method. One activity can shut down another activity (one it started with startActivityForResult()) by calling finishActivity().
- A service can be stopped by calling its stopSelf() method, or by calling Context.stopService().
- Components might also be shut down by the system when they are no longer being used or when Android must reclaim memory for more active components.
If the user leaves a task for a long time, the system clears the task of all activities except the root activity. When the user returns to the task again, it's as the user left it, except that only the initial activity is present. The idea is that, after a time, users will likely have abandoned what they were doing before and are returning to the task to begin something new.

An activity has essentially three states:
- It is active or running when it is in the foreground of the screen (at the top of the activity stack for the current task). This is the activity that is the focus for the user's actions.
- It is paused if it has lost focus but is still visible to the user. That is, another activity lies on top of it and that activity either is transparent or doesn't cover the full screen, so some of the paused activity can show through. A paused activity is completely alive (it maintains all state and member information and remains attached to the window manager), but can be killed by the system in extreme low memory situations.
- It is stopped if it is completely obscured by another activity. It still retains all state and member information. However, it is no longer visible to the user so its window is hidden and it will often be killed by the system when memory is needed elsewhere.
- If an activity is paused or stopped, the system can drop it from memory either by asking it to finish (calling its finish() method), or simply killing its process. When it is displayed again to the user, it must be completely restarted and restored to its previous state.
- The foreground lifetime of an activity happens between a call to onResume() until a corresponding call to onPause(). During this time, the activity is in front of all other activities on screen and is interacting with the user. An activity can frequently transition between the resumed and paused states - for example, onPause() is called when the device goes to sleep or when a new activity is started, onResume() is called when an activity result or a new intent is delivered. Therefore, the code in these two methods should be fairly lightweight.

The following diagram illustrates these loops and the paths an activity may take between states. The colored ovals are major states the activity can be in. The square rectangles represent the callback methods you can implement to perform operations when the activity transitions between states.
tl;dr version
- Android is hard coded to automatically kill a task when more memory is needed.
- Android is hard coded to automatically kill a task when it's done doing what it needs to do.
- Android is hard coded to automatically kill a task when you haven't returned to it in a long time.
- Most services (while possibly running in the background) use very little memory when not actively doing something.
- A content provider is only doing something when there is a notification for it to give. Otherwise it uses very little memory.
- Killing a process when it isn't ready only causes it to have to reload itself and start from scratch when it's needed again.
- Because a task is likely running in the background for a reason, killing it will only cause it to re-spawn as soon as the activity that was using it looks for it again. And it will just have to start over again.
- Killing certain processes can have undesirable side effects. Not receiving text messages, alarms not going off, and force closes just to name a few.
- The only true way to prevent something from running at all on your phone would be to uninstall the .apk.
- Most applications will exit themselves if you get out of it by hitting "back" until it closes rather than hitting the "home" button. But even with hitting home, Android will eventually kill it once it's been in the background for a while.

Lets use some basic mathematical skills here. Indeed I just tested this for an hour straight and the drain was 150-200ma constantly. The HD2 battery is something like 1200, 1300ma whatever in total. Lets say its 1200 (too lazy to check) that divided by 200ma drain equals six. Six hours so your logic goes out the door.

Well, I'm 100% sure it affects you too. You can't just create energy out of nothing. Upping the intensity from lowest to highest easily adds in an extra 80mA, and that's just a rough and probably too low estimate.
Have you ever compared you HD2's battery with a laptop battery? Not quite in the same league of size now is it. Moar size = moar powers (well, kind of). Dumb laptop comparison, sorry to put it like this.
You can go ahead and try to reinvent battery usage all you want, but a 4,3" screen is and always will be one of the major battery hogs on a phone like this.

Uhm actually there has. Moar CPU = moar heat = moar power loss = moar battery loss. Again, conservation of energy, which could be found in the book I advised you earlier (well actually a thermodynamics book would be more appropriate).
