Has anyone noticed any long term disadvantages to overclocking the Wizard? Does the battery life permanently decrease? What speeds are you running yours at, and how long have you been doing it? Have you noticed anything at all which indicates it's not good for the hardware?
Cheers
reply
i believe that it's safe to overclock the mda...just set it at an acceptable rate (264mhz for me) and make sure not to run the battery all the way down...if you overclock the settings too high the device will freeze and reset (this is a fail safe procedure it goes through), so there is no need to worry...also don't overclock the settings too low as the phone becomes disfunctional when too low (about less than 132mhz for me)...the screen flickers because it's not being refreshed quick enough (my guess)...hope this helps...
I would set it to 240. I have done before, i'm just wondering if it's a bad idea leaving it permanently set to that level?
Cheers
yea you should be fine at that speed, but if you want you can overclock it higher if it will let you...just make sure that the phone is stable when using it...like i said in my earlier post my device is oc at 264mhz
Cool, thanks for your replies. How long have you had yours overclocked for? Do you use Smartskey?
Cheers
My self i ownly use it when need the extra speed, only with some games and wmv video files. I think it definitely lowers battery life and i would have worries about overclocking all the time and the long term effect it has on the processor (not so important if you only keep your wizard for a year and then change with a new contract - what i do new device once a year!) I found good speed gains with the registry wizard - http://forum.xda-developers.com/viewtopic.php?t=39725
have not found overclocking produces that much extra speed.

Mine is also set at 264 24/7. Battery still lasts me all day. Been doing it since the oc program was found which I guess has been a couple of months.
Don't forget, you're wizard is only overclocked when it is active (i.e. not in standby mode). When your wizard goes into standby, it automatically goes back to the default 180mhz. Only when you bring it out of standby does it overclock again (assuming you're running it with smartskey with the option of overclocking on wakeup)
i'm using smartkey to constantly run at 264mhz...i have been doing this for a month now...like i said there is not really any problems with the batt unless you run it down totally...there was a post about this in the overclocking thread...the process is set low so that the phone will have a longer batt life...this was also stated in the overclocking thread...theoretically there is more wear if you overclock it since you are making the processor work harder, so use it at your own risk! if you want to be on the safe side then use smartkey and the overclocking prog in the same directory...then use total commander's note pad (while the ini file is highlighted) and change the value lower when you don't want it to constantly run at 264mhz or whatever speed you want to overclock or underclock at...just use it when needed, but i overclock mine constant 264mhz with great results combined with tweaks2k2, registry wizard, and of course the tmobile custom rom ...internet is a blast...just wish i could get it to run like the IE in a pc
anyways hope this helps out a bit further...
activesync
your activesync will hang allot if you overclock, I have noticed this.
DOnt know why.
For some reason i stumbled onto something, im sure its been mentioned b4 but when running Wisbar advance with a Windows vista skin done by xcillion, i am able to overclock my cingular 8125 to 288mhz at a stable rate with no problems at all, can run warcraft 2 full speed with over 50 units battling it out on screen, almost doubles browsing speed and i can run all the emulators including SNES at full speed with sound. when i dont have wisbar advance running i cant go past 240mhz clocking speed. I wonder has anyone else noticed this or gone higher than 288 without a freeze. Also, my battery life runs steady for a full day of browsing the internet talking on mobile messanger and listening to music at half volume for a full day.

hey sonic, where did you get your copy of warcraft 2 for windows mobile ?
I've never heard of warcraft for Windows mobile, how does it run on a 240 MHz overclock?
I got it from the Wargus engine. i can email you the files if need be, i dont want to jeprodize this sites reputation. The game last time i checked was free though...
Actually I'm not sure if it's the overclocking issue or not but ...
For couple of weeks now my Wizard's red led is on all the time, not like it is when your battery is very low but about half of this brightness. I'm not really worried about that, it doesn't change much but it may be connected with overclocking (it was 240 for about a month).
Another thing - once I had sth like 110% speed of every tone played, either a phone call or an incoming message.
It doesn't really matter to me since it's still working fine but it may mean that overclocking isn't that safe as we might think.
TroLoo
So I am at work, looking at my N1, and I'll let you all tell me if you think there is a problem...Since a full charge last night, my phone has been off the dock for 2h9m ...
In that time, my battery has dropped 14% already. The biggest culprit...the display...with 59%...despite only being on for 15m. I always use it on the middle brightness setting from the power bar. Ive lost basically 1% for every minute the screen has been on. At that rate, my phone wouldn't even last 2 hours turned on.
Am I being paranoid? Do I have some rogue program sucking battery life? Your thoughts?
Everybody says controversial stuff about phones like N1 or iPhone regarding battery life. But I can tell you from experience and some conferences I have been the following tips to improve your N1 battery:
-Leave brightness to minimum. Only at street you will need to have it at medium or maximum so you can see well.
-Use 3G or wifi when available. It will save more battery than if you use edge.
-Use push, also it's better.
-User apps like TaskManager to auto kill some application that remain open.
And last thing, if you have a new N1 the battery life will improve with the use within the next 2 weeks. Also, I'm sure you are playing around more than usual if you just got it.
I hope this help you.

Battery History
See what the figure for 'running' is, if it's high, something is stopping the phone sleeping. Should that be the case, chage the top drop down box to 'partial wake usage' and see what is to blame.

This is the complete opposite of what everyone else will tell you.
Most people say to force 2G (Edge) because it'll save battery over 3G. There are reports that WiFi will use less battery than 3G though, but not as good as 2G. Google even says this on the screen where you force 2G.
Push Email will require a constant polling on the internet. Since Android is a web OS, its probably connected to the internet anyway, but you can disable Auto Sync and Background Sync to save battery (once again, Google says this on that screen).
I agree with #1 and #4 though. If you don't want to do the lowest brightness setting, try the Auto Dim, it seems to dim it a lot more than my old Windows Mobile phones did.

@mindfrost82. Check out the video, it will tech you few things because most of people is wrong as I was in the past.
Battery Drain
My phone would drain 15% battery in 1 hour just being idle witht he screen off. I dialed *#*#4636#*#* and changed the option from WCDMA preffered to WCDMA only. When I don't get a 3g signal (not often) I jsut go back to that and set it to GSM only. For one reason or another the WCDMA preffered SUCKS THE BATTERY!
4 hours of the phone being idle and only 5% battery drain! DO IT! IT WORKS!

You need to be careful of this. The point the video made is that if you download something OF SIMILAR SIZE, you will realize battery gains by virtue of the fact that what you are downloading/uploading takes exponentially less time to retrieve. The real question is, if 2 phones are both casually browsing for the same amount of time...without worrying how much information was actually transferred...one on Edge, the other on 3G...is there a difference in battery performance?
What the video said is just common sense. If I am going to send you 20 MB file and one way takes 2 minutes to download it and the other takes 10 minutes to download, then OF COURSE the 2 minute method is going to be more efficient. So you can download on Wifi where it might take x amount of time, compared to 3G where it takes 5x or edge where it takes 10x. Thus, if the file size the person is going to download is known, then of course it makes sense to tell them to wait until they are on wifi. However, many of us casually browse, on the spot, without regard to the type of connection we are on.

Yeah, what you just said is right. But still you are saving battery up! Plus I wouldn't use edge at all in my N1. What's the point of having almost everything disabled so I can receive calls?
I remind you that while edge is sending/receiving data you cannot get any calls

Thanks, I didn't know this, for the info this thread is full of great stuff...
1) middle brightness is very bright. I'm sure you can live with 25%. Display brightness will always drain battery like mad.
2) 3G power use is usually decent. The N1 has terrible RF so it might be fighting 2G/3G. That will cost you a lot of power. If you're getting full 4 bars 3G everywhere you go even underground, you might be ok, but in low reception areas, it's gonna drain your battery struggling to boost power. Bigger issue during a call too.I notice this on my Milestone. The N1 completely fails at 3G while my Milestone fights for it. As a result the Milestone gets quite hot.
3) There are sometimes apps that run in the background. Some people insist task killers aren't necessary, but lemme give you an example. Stupid Speedtest program failed to acquire my location. After a test, you can't really exit, so you just hit home. Droidforums fanatics will always repost that link to that one thread where they talk about memory and its ok to not have to kill an app. Think again. The GPS turns on because of Speedtest and it keeps trying to acquire your location. Gotta kill it with a task manager or that thing will kill you. Or a webpage. I've heard of people going to some site that keeps refreshing. Oh good luck to your battery. Make sure you close these things. Use a task manager. Sometimes Facebook or Twitter might be the culprit even if your refresh rates are awfully long. I do not understand this phone sometimes. At times I feel that multitasking/memory management on Android gets you into more trouble than if you just flat out restricted it like in the iPhone. I'm not saying the iPhone's restrictions are the way to go, but Apple knew what it was doing. There's a reason Android phones gobble power and pull data like mad even when you aren't aware. Random apps sometimes start. Facebook widget refreshes even though the app itself is set not to auto notify and to update on its own. So with so many things running loose, its quite easy to see why your battery can go down so fast.

I'll second this, I never used to use a task killer as I figured it was just extra drain on the battery but after running across some rogue programs that kept running after being closed and draining the heck out of my battery I decided to install taskkiller and set it up to autokill apps when the screen goes off.
It's really easy to setup just install it from the market then use it to kill everything then flip through your homescreens make sure everything is up and running and go back into task killer and add everything there to the ignore list and turn on "autokill when screen off" now you don't ever have to worry about rogue apps killing your battery again and everything else will function normally.

I'm sure 100% that while phone is receiving data over edge you wont get calls. I know because I had push enabled and afterwards I was getting SMS from my carrier that I have missed calls. It might say "ey sb is trying to call you" and then stop data transfer but for sure your will miss first call if someone is trying to reach you several times.
Check it out yourself.

there are a lot of people who say do not use a task killer, including google devs etc.
i used advanced task killer for the longest time, being used to needing one as a WM user before getting my n1. after reading various posts on the issue, i tested without and my battery life increased.
i use juice defender now as well to turn off the apn and wifi, based on speeds/location/etc
have it set to prefer 2g (dont get 3g at home)
screebl also setup to turn screen off when not in certain position in hand
last one is setcpu (need root for this though) underclocking the cpu (including advanced setting and profiles i have set)
lowest setting for brightness
also keep gps off unless needed
i hit about 24hr from unplug til 10% w/ heavy useage, wifi on all the time (although juicedefender handles when its on/off)
just now went to kmobs UV kernel and testing that to increase my times
i've done a 24hr test from 100%>10% based on each app i've mentioned
I think while we are on topic of battery life.. for those of you who are rooted. Here is another link that I would recommend. I used these on my HTC Dream and works great on the Nexus One. Increase your battery life 10 fold.

Hi,
I'm posting this in return for all the information I found about the HD2 and poor battery performance. I read every thread I could find and every single post in them. I learned a lot and that allowed me to solve my problem.
I got no more than about 10 hours of use out of my battery with average use. Initially I thought this was the norm, reading a number of threads on this issue. I could however not believe that the performance was so poor, even taking the large screen into account.
I decided to try and determine exactly what it was that caused the battery to drain to quickly. I loaded BattLog and found it invaluable (see http://forum.xda-developers.com/showthread.php?t=444920).
I immediately noticed that my phone was drawing 85 mA even when it was in standby (or what I thought was standby). Based on what I was reading, the current draw should not be more than 5 mA while the phone is in standby.
I noticed in one of the threads that there were complaints about G-Profile causing battery drain. Since I had it on my phone I thought that might be a logical place to look. I uninstalled it a lo and behold... the current draw fell to below 5 mA when the phone was in standby!
In addition I loaded Bandswitch which switches off my 3G connection after it has not been used for 60 seconds.
Now I have about 48+ hours of battery life. When not using the phone a lot it extends to a lot more than 48 hours.
The long and short of it is that if you get poor battery performance, chances are it is because of some software that is installed on your phone.
Here are a couple of usefull things I have found in helping resolve my battery issues:
1) Use Batlog (http://forum.xda-developers.com/showthread.php?t=444920) to log the current your phone draws. If it draws more than 5 mA during standby you have a problem, most probably related to a piece of software on your phone
2) Your phone should not be drawing much more than about 150 mA when in 'active' mode with the screen at 40% brightness.
3) If you are running G-Profile, uninstall it and recheck your current draw. Chances are that it is the culprit.
4) Having an active data connection does draw power from the battery. In my case this is about an additional 130 mA. Load something like Bandswitch to disable the data connection when it is not needed.
I hope this information helps somebody. I realise that the situation is different for everybody out there because of all the variants such as age of the battery, sofware loaded and use. However, the reality is that the battery issues are most probably not because of a bad battery or the hardware but rather because of software on the phone.
BTW I am running:
OS Version: 5.2.21869
Manilla version: 2.5.19211619.0
ROM version: 1.48.421.2 (71294) WWE
Radio version: 2.05.51.05_2

and imagine that your rom version is accused of massive batt draining!
an upgrade to 1.66 / 1.72 should make a difference..or a custom rom
batlog?
Hi Gerhardvr,
What is the batlog software you used?
I'm very interested about your post.
Thanks.

Very useful findings, gerhardvr. Thanks!

When I ran the Test, it said that I was using up 242mA in standby! I dont believe I have G-Profile installed, unless it was pre installed on the device. I have the latest versions of the ROM, Radio, Manila, and OS version, so I know the culprit cant be the ROM version... Any ideas? I bought this phone from T-Mobile US.... Sooo yeah
Folks, I've been trying to get to the bottom of this as well. I have a number of cab files which do seem to help a little. One of the bigest culprits I've found is the screen lockers. Disable them and see how you fair!

Soopahsteve,
I suggest you use Battlog to log to file. This is very useful as it will log the time stamp, the current temp of the battery and the current draw at the point in time. In addition it logs arious events on the phone, in particular the startup and shut down of applications, data connectivity, when you make or receive a call, whether you are talking or receiving on the call, etc. This can be opened in Excel and then analysed and if you are very lucky, you will pick up some patterns allowing you to link some programs to the battery drain.
However, the situation is typically slightly more complex to resolve since the culprit software are usually software that is loaded as TSR application at reboot. The result of this is that Battlog will not show the startup of these applications in the log file since they are already running at the time you are starting Battlog.
You should look at programs that manage phone profiles, screen lockers, screen calls or SMS messages, etc. In other words, any program that does work behind the scenes.
The reason you are seeing 242 mA in "standby" is because your phone is not really in standby. Although the screen is blank, something is preventing your phone from going into true standby, the processor is still active. The trick is to find what this is.
Sometimes the only approach is to uninstall the applications you suspect one by one and see if it makes a difference until you either find the culprit or can prove that none of the them are an issue. Then reinstall the ones you think are "safe" one by one and check whether the probelm pops up again. unfortunately you have to do the double sided approach because there could be more than one application that cuases your issue.
Painful I know but worh it when you have two days worth of battery time with some to spare.

See no reason to upgrade to the latest ROM

and imagine that your rom version is accused of massive batt draining!
an upgrade to 1.66 / 1.72 should make a difference..or a custom rom

You know it. In reality I would love to upgrade to the latest and greatest but I've customised my phone to the Nth degree (did obviously not upgrade the ROM) by installing all the little apps I find useful, Cookies Home tab (best thing since sliced bread), etc. My phone is now just the way I like it.
It would take me quite some time to upgrade the ROM and to customise it again from scratch and I really don't see the benefit. I might be force to do it when I get to a stage where there are software that I would like to load that only works on the later ROMs but until such time I'm not gonna try to fix that that ain't broke.

is this the bandswitch u are using? if not, can i check where to get the program?

I just upgraded my ROM and did a Level 1 restore with Sprite Backup ... everything comes back except (I think) for wifi passwords.
i am drawing 180mA on standby..
im using custom rom, energy rom so thats very strange, but i have to agree that my battery life is terrible.. so i got to find a way to cut down on the 180mA drain..
I've always had good battery life on stock 1.66 rom losing 3% overnight with wifi and bluetooth turned off. Had to do a hard reset and started losing 15% overnight with the same everything. Did further resets and got nowhere. Ended up giving up on 1.66 although it had been fine previously after numerous hard resets - makes no sense but this is what happened. Just flashed to 1.72 and back to losing 3% overnight what it should be. And that is out of the box, to be honest all the battery saving registry tweaks are not worth the time installing and I leave 3G on all the time with updates coming through.
So it's all a bit random and shame on HTC for not sorting it out. My advice is do a hard reset, switch the wifi and bluetooth off and see in the morning if you have a reasonable battery life (or use the batt consumption program to verify standby consumption is sensible). Do this first before installing everything, getting frustrated and starting over again like I did when you discover that you're still experiencing high battery drain. This ensures that your starting point is a good flash and the phone is getting good life before adding any apps that could be causing a problem.
i have found my hd2 really does not like being in a poor or no coverage area. other phones i've owned have normally coped pretty well with no or very little signal. but not the hd2.
also noticed more drain in areas where there is only poor 3g coverage and its switching between 'g' and 'h' coverage.

Energy ROMs, just like the name goes, use a lot of Energy
They are baked in with a lot of performance tweaks so it's not unusual to get lower battery life per charge compared to other more down to earth vanilla ROMs.
Thanks for this thread, a lot of interesting information about the battery life of my HD2.
Just to mention: battconfig shows the power consumption directly in the task bar, a good way to find power guzzlers while they are active.
It's a pity we have no central place in this forum with a list of background applications that are known to drain the battery faster.
Or, also a needed information, a list of applications that are known not to do this (like PhoneAlarm, PocketShield).
I'm using the official rom only and have non fancy apps running or installed while I'm using the test bat program. As I speak the SD card is removed and celular radio is turned off.
Acording to program there is an indicator which is switching from -229ma to +78ma is that what its drawing of power?

+78ma??? That must mean you are charging the battery. The best way to test current draw is when it is only on the battery.
I get about -5ma draw on standby and it tops out at around 180ma when I have the screen on, but usually hovers around 130 - 150ma. I have my screen brightness at the lowest setting possible.
@OP, I wanted to say this earlier... great topic, very insightful.
I have a few suggestions for everyone posting in this thread. Let's try and get some common data together that is more tangible in order to give us a more similar & common perspective for these discussions.
I suggest the following
1) Soft Reset. Once the device is on, do not run ANY applications. In fact don't do anything except for following the below instructions.
2) Turn your screen brightness all the way DOWN! (Turn off Auto Backlight and manually set it to the lowest setting)
3) Check your power settings and make sure that while your phone is on battery, that it is set to dim the backlight after 30 seconds and turn off after 1 minute
*** I have attached 2 REG files below for both Backlight and Power. Please use them instad of doing it manually.***
4) Turn off all the radios (Phone, Wi-Fi, Bluetooth). Let's make our first round of tests with the Radio's off. Radio ON complicates things a bit as there are several applications to keep track of that use the Data Connection. I'll come up with a more comphrehensive list later so we can do the Radio ON tests.
Screenshots
Use a program like Shave&Save and get the following screenshots
1) Use any Task manager and get a screenshot of all the processes running. Sometimes the number of processes displayed is longer than the screen size can accomodate. Take 2 screenshots in this case making sure that you capture all processes. Edit the image with MS Paint or some other Image Program and attach it here as one image. See the example in the post below this one.
2) Goto \Windows\Startup and get a screenshot of the folder contents
3) If you are using Sense, drag the slider all the way to the end (settings) and goto About Phone. Goto Software Information and get a screenshot of that.
Monitoring the Battery
1) Make sure your phone is not connected to the charger or to the computer.
2) Open BattLog (can be found here), set the refresh rate to 1 second and Start Logging.
3) After you start the logging process do not touch the screen / the phone again for exactly 2 minutes.
TIME THIS with a stop watch. As soon as the 2 minutes it complete, turn the phone back on and stop the logging.
Information to post here
1) All the screenshots from above.
2) The current draw (both on standby and while active). Also, please attach the file that logged all the information in this format: Forum ID - BattLog - dd-mmm-yy.txt
3) ROM - Whose ROM? Release Date? Does it have Cookie's Home Tab Installed or any other MAJOR Sense Modifications.

SAMPLE POST
HTC HD2 (T8585)
OS: WM 6.5
ROM: Energy * Build 21907 * Release 01.JULY.10 * CHT v1.8.5 - Dinik Edition
RADIO: 2.07.50.27_2
Current Draw (mA)
Idle: -3 to -7
Screen On (w/o Radios): -83 to -117
Those figures look normal to me. You should be getting about as good a battery life as a device like this can achieve.
Ive been using juice plotter to check on my huge batter drain over the last few days since installing darkstone froyo v2, ive been slowly adding different apps to control the power consumption. I understand all rooted android roms have similar issues, hopefully a combination of these apps will help.
from stock darkstone froyo (ie no power control apps) i was losing 90% of battery in 7 hours. This was with wifi/gps/bluetooth off and not much usage. I also found the phone Stopping at 93% charge when plugged in. To fix this leave it plugged in and turn the phone off for 15 mins. Reboot android and It will have reached the full 100%. I think the android rom I have has issues charging on USB so I disabled the charge on USB in the settings.
Ok here are my personal findings I have on various power saving apps.
APP: JUICE PLOTTER
RATING: 4/5
BATTERY SAVED: N/A
PRICE: FREE from app store
shows a graphical chart of power consumption vs time , good for diagnosing how much extra power draw your activated features have (ie wifi, bluetooth) shows the time these features start and end at also, be it manually started or automatically.
APP: APP KILLER
RATING: 4/5
BATTERY SAVED: 30 - 60 mins on a full battery
PRICE: FREE, Pro upgrade is minimal cost from app store (gives extra features)
I set mine to aggressive killing. this improved my battery slightly, probably increased battery by about 30mins to 1 hr on a full charge. The main thing I like with this app is the automatic, set time, multiple killing of other apps. Unfortunaly i found the app killing not to permenant as some restart again a little while after. This has minimal battery save for my programs but depending what your apps/services are consuming on terms of resources, it can save much more. The auto kill stops the phone from been bogged down, it is much quicker to respond once its stopped other apps and wakes from sleep quicker. This app also shows you a list of all current running apps and services that you can quit, switch to etc. I found stock android to have this sort of task manager feature missing.
APP: SETCPU
RATING: 3.5/5
PRICE: free on XDA (donation recommended ) small price from app store.
BATTERY SAVE: about 1 hr - much Cooler running phone temp.
This app is very good as it can set you CPU speed to save battery. Mine is set to 833mhz when used, 255mhz in idle. 432mhz when the screen is off. This Saves small amounts of battery but still has a decent response and speed, also improvements on wake up from sleep. You can save more power with more conservative speeds, although your phone may be less responsive. On the flip side push up the MHz to increase speed and responsiveness of your hd2 for increased battery usage.
Upon heavy use of my phone with a high CPU speed I saw a slight battery drop with SETCPU, probably due to my CPU speed being at 1033mhz at the time.
CLEANED MY EMAIL INBOX
BATTERY SAVING: 7 hrs
I found that mobile web was constantly running on android. as I hadn't cleaned my email inbox fully a few emails from a month or so ago kept been synced to my phone to notify me. Once I deleted these My battery saved near to 7 hrs per full battery. I assume it was constantly downloading the old emails. So make sure you email account is maintained.
APP: TASKER
PRICE: just under £4. Cheaper from developers site
RATING: 4.5/5
BATTERY SAVE: 15 HRS
This is the greatest power saving app I've used.
I've set my mobile data to automatically be off. Every half hour it will turn on for 5 mins to update emails, news, weather etc. It will also enable web when I unlock the Phone. Disable web once I've turned off the screen. It also stops syncing at night so it doesn't wake me with a notification sound. This saves me an extra 15 hrs on a full battery.
One thing I'm doing next is to stop certain apps from booting until I need them. sort of a scalpel approach as apposed to app killers kill em all method.
one issue i found is the learning curve to be quite high on tasker but it wll only take 20 mins to get the hang of how to do what i did above. Hopefully the deveoper will make an easier interface but its still very good. The power saving feature of tasker is only a small part of the tasks this phone can do. It can literally Automise most tasks for your android.
Wth all these apps my battery now lasts on average for 24hrs upon normal usage, 30hrs+ on light usage (better than my win mob) and around 18 hrs on heavy usage.
Hope this helps any one looking for a decent power app. feel free to add your experience with these and oter power saving methods for android HD2
interesting thx.. so tasker is just a automater it doesn't actually stop the apps from staying open in the background or can it? thats the thing annoying me i kill all apps then i go check and i see useless apps still running in the background and i don't want to have to uninstall the apps just to disable them from running in the background. btw did u try the text to speech on incoming calls? im thinking bout purchasing it.

yeah tasker can be made to stop indivdual programs from booting rather than app killers stop em all. tasker keeps em stopped until you want to run them of course. you have to select scripts to do this tought. The program is amazing, you can auto set your phone to go silent when you walk into work, cinema etc etc by using GPS. Auto connect to car bluetooth once you get in your car, connect it for calls then stop bluetooth once you get out. Have your phone read you your messages once you have navigator on in the car, so you dont need to touch it. send an automatic sms reply to certain people, ie work collegues if your in a meeting..... its a full automisation program, the options are endless if you know what scripts to select to get it working.
I sadly can only do basic ones but in willing to learn, there are a few tutorials online for certain tasks, im just hoping the developer will release updates to make it easier for the advanced tasks.
lol ive just read this back and BTW i dont represent the developer in anyway, i only bought the app 3 days ago. I did a bit of research on it as thought it was a bit expensive and im glad i did buy it, it depends what functionality you want with your phone i suppose. I bought it as it cures my power options and i can taunt my mates who have iphones (i received a lot of stick when it had winmob on as the main as it kept having issues and wasnt very fun for me to use).

great thx.. yeah ive been trying to find a good app that would help make things a bit easier especially when driving and reading txt messages is a plus, if u recieve calls does tasker say aloud the caller name while the ringtone is still ringing or does it replace the ringer? ive had issues with other speech announcers.

Im not sure in all honestly, ive not really got around to looking into other tasks apart from battery power saving ones. ive read a few of the posts on the developers website forum and he seems very good and swift at answering questions on the apps features. He also has a suggestion page for users to add stuff. Its one of the reasons that swayed me into buying it as hes clearly spent a lot of time on the development of the app, is very active on his site and seems update the app with newer features. His site link is on marketplace with his app.
Update; I've just checked my battery as I left if off charge last night. It was 48% when I went to sleep its now 40%. This averages at 1% per hour!!! Battery usage has now increased that I'm using it.
How do you setup your tasker? I got it but have no idea how to use...
why i cant find tasker in market??

Uhh, I cannot post this in development as I am still a newby :-(
However:
Hello,
I came from Symbian (Nokia C7-00) and liked the phone very much. Everything worked the way it should. (I was especially interested in office functionality.)
Now I bought a Galaxy Note and I really love the hardware.
But I discovered that it uses much energy and it doesn't like to sleep as often as it could. (I already returned to Android GB, which gives a better experience, but there still is room for improvement.)
1. Sometimes even though the phone simply lies around and does nothing, the last app that I forgot to close is hindering the CPU from sleeping. Why? The is no need.
2. At night I am used to turn the phone into flight mode. However I found out that this isn't the best thing for Android. In the morning, when the email app goes to push phase, the phone leaves sleep mode and seems to excitedly wait for the flight mode to get switched off. This uses *quite* a bit of battery!
These things seem strange to me. My impression is that Android is not really optimised for cell phones. If the screen is off, there is no need for CPU time, doesn't it? There is nothing urgent to do; everything could be done slowly; no hurry.
I guess the battery could last *much* longer if this would be improved.
Greetings,
corcov

Doesn't matter.
Development, if you did not create IT, then it does not belong in development. Remember that. Otherwise you will get flamed.
Android is a mobile OS, so of course it is optimised for smart phones - not ordinary cell phones. Android acts like a computer and, if you keep a computer running Crysis 2 for example, it would burn more power than a computer just playing some music off of iTunes.
In terms of improving your battery, check your brightness. You can download widgets to adjust the brightness right from the home screens. I use these to set my brightness to its lowest whilst at home (perfectly adequate for night and indoor use away from sunlight) and turn it onto automatic when I go outside. This has saved my a bunch of battery.
If you are running a stock Samsung ROM, turn on power saving mode. I always leave it on and, frankly, I have no idea as to what it actually does. I haven't noticed a performance drop in the slightest, but if it saves a bit of battery it is worth it. Also, you could try Juice Defender or some other battery saving apps which work for some people - others not.
Finally, ensure you haven't left GPS, Bluetooth or WiFi on when not needed. Try downloading CPU Spy to check your phone deep sleeps, yet mine even without it ever deep sleeping gets around 16 hours of battery life which is still the best I have ever gotten on a smart phone. Bettery Battery Stats can show you wake-locks (apps that are keeping your phone active) also.

I see. Well it might be a nice feature if one could add an "now be a cell phone"-option for energy enhancement, which means: if screen if off, sleep.

There are some legitimate needs for keeping the CPU from sleeping for a short period of time - such as finishing a sync operation (otherwise, the radio power spent beginning the sync is wasted). Unfortunately, some poorly written applications (Facebook for example) abuse the wakelock mechanisms and hold wakelocks when it is not justified.
2. At night I am used to turn the phone into flight mode. However I found out that this isn't the best thing for Android.

This is not something I have ever encountered myself. "push" relies on the server to trigger something - in airplane mode, this trigger can't happen.

Android is well optimized for cell phones - However, it assumes that third-party applications follow Google's recommendations for power management. Unfortunately, many of them do not. The number of IM applications which choose to use their own proprietary and poorly optimized network protocols (such as Skype, it's atrocious) as opposed to Google C2DM (optimized and efficient) is astonishing.
An interesting note was that I believe much of the focus at Google I/O was on reminding app developers that they need to play nice with the system and other apps.
There are some cases where there are device-specific nonoptimalities. Compared to most Nexus devices, Exynos devices have an absurdly long time to resume from wake (1000 milliseconds), and during that resume cycle CPU frequency is locked to 800 MHz and cpuidle is disabled. This is one of the #1 causes of power drain on our device. This is also exclusively a Samsung kernel/hardware architecture problem that does not affect the Nexus S (similar CPU, but completely different modem interface) or the Galaxy Nexus (different CPU/modem interface).
In the case of our device, the modem is hung off of the CPU on a USB bus - this makes for very long resume times.
Here are obvious reasons the CPU should occasionally turn on when the screen is off:
1) MP3 playback in the background
2) Handling of background syncs - e.g. when an email or Google Talk IM comes in, wake the CPU, handle it, and pop a notification sound, then go back to sleep. Normally, this means the CPU sleeps while waiting for an interrupt from the WLAN chipset or the cellular radio. Unfortunately, some apps drive incoming data to the device far too frequently. (See my above rant about Skype's network protocols being crap compared to Google's C2DM protocol.)
3) Handling of scheduled wakeups (alarms, calendar events, etc) - these are rare and almost never consume power
Most power drain is from item 2, with third-party apps frequently behaving extremely poorly compared to Google's own application suite and sync protocols.
Now this an extensive answer which is very informative and helpful for me since insights are always soothing. Love it. Thanks!
not much to add after Entropy, but if you feel the need to get some control over battery usage you could try betterbatterystats app (and the thread) to identify battery eaters, besides that, there are few apps to check what is going on with your system when it sleeps:
- CPU Spy to show cpu states time
- Autorun Manager or Autostarts to disable triggers causing apps like FB to run without reason (those which you will find with betterbatterystats)
- Battery Monitor Widget, to check battery current consumption (mA) - this app is generally not recommended, because Note's hardware does not report the actual current, so the readings are highly estimated and because when poorly configured it can drain your battery faster, BUT otoh with refresh rate set at 5 minutes or more, it can give you some approximate orientation on how much battery you lose (better than counting %/hour by yourself) at negligible battery usage
- also, if you feel the need to disable net and sync during night, you could automate it using "lama", which is free, and in my experience does not eat much battery by itself
- and last but not least, avoid taskillers, those apps may have adverse effect, i.e. self restarting apps (by the triggers mentioned above), will get killed then restarted and so on and so on, leading to much higher battery drain
