So I've had my Touch "enhanced" for a bit over a week and I'm having some annoying issues regarding battery life. I'm charging this thing once at least once a day, twice a day when I'm using it a bunch. I've messed with the power settings, and the phone goes into standby after 2min. The only 3rd party software I have is touchpal, everything else is factory. I was just trying to gauge some input from other users. I did call HTC, and was greeted by an ass of a warranty tech, who, after getting my problem explained to him proceeds to ask me what I want him to do. Wow. Then he tells me that a new battery won't be instock for two weeks! How frustrating!
Thanks in advance.
You should get at least a day even with medium-heavy use. Up to two days on average.
If you install the excellent Chi-Dai Battery status plug-in then that will monitor the power drain on your battery. It will tell you if the problem is software or the battery itself.

Thanks, I was about to download something to moniter the consumption. I'll give it a shot when I get home from school
I have the same issue with my battery. I use it for med-heavy. By the end of the day Im at like 15%. That sux.
I've installed S2U2...does this application drain the battery also?
monitoring your battery life won't do anything when you want to increase it
if you want to save battery life
it's likely that you have your wireless radio's turned on while they don't have to be,
go to your comm manager
WI-Fi drains A LOT of power and should be on only when you plan on using the internet
your GSM phone radio can also be turned off, useful when you're not in an area covered by your carrier when this happens your device panics and sends out signals to connect to the antenna tower this extra cell phone activity is bad for your battery life... and your sperm count
bluetooth takes an insignificant amount of energy to power
lastly pressing the lock button on the device is useful because it turns off the screen but keeps the device on using these features allows me to have my device unplugged for 2 days

2 DAYS UNPLUGGED? Are you kidding me. On standby or using it. Im thinking this battery is horrible. If I dont plug in every night, im in trouble.
If you want to increase the lifetime, use Battery Status software and activate CPU Scaler, it's great!
Before: I used only 201Mhz freq, my battery had a lifetime of 1 day using it normally.
Now: I've overclocked it to 260Mhz with CPU Scaler activated (low: 99Mhz, average: 201, max: 260) and my touch can stay 3 days without charge need.
I still use these settings but I have a unlimited data contract with my operator, so my touch is connected all the time to Edge (push mail and weather updates), and with these settings I have to charge it every day. Don't care about this since I work with a PC all the time.
I think if I used all the time the original freq, I'd have to charge it more often...
CPU scaler
I have Battery Status ver. 0.5 but don't see CPU scaler, is it only available in the Beta version?
1 to 2 days of life with normal-full use. Up to 4-6 days in standby with almost no use

Can you please give me more info on the battery status software and cpu scaler?
Do you have an Elf or Elfin?
I've an Elfin.
Battery Status is a today plugin you can configure and use to overclock and set CPU Scaler.
Here is in attachment the version I use
Overclock and CPU Scaler are only available for OMAP processors, so for Elf/Elfin it will work.

I turn off the wi-fi when I'm not at home. I'm always within service area, so the GSM radio stays. I don't use bluetooth. It's set to go into standby mode after 2mins. On Thursday, I took it off of the charger at 8:30am had a couple classes till 3pm, so light-to-medium use. It was dead by 3:30pm. I did install BatteryStatus later that night, and figured out the scaler, and it helped the next day. But honestly I shouldn't have to underclock it in order for it to last even a day, a bit ridiculous to me.

I have a Touch enhanced, and am using the CPU scaler just dandy. Just play with the settings a bit, and you'll get the hang of it. Try LOW:100 and HIGH:234, to start out, then go from there.

Visit the Kaiser forum. We're having the same issue. GPS seems to be the problem with me. As soon as I turned on GPS, it sucked my battery 5% in 5-7 minutes. Then down to 73% from 97% in 3 hours.

I didn't configure anything particular, just installed it and set the overclock and CPU Scaler.
I talk an average of 2 hours daily. Since 6 am until 8 pm. I always get home with 15% or less. Using batt status with omap overclocking to 247. Average use of pda also.

Right on brotha. It worked great! I was wondering whats the lowest low you can use to conserve battery? Im at 98-low 247-high, using CPU scaler.

Im on 87/201/247 and boost to 260MHz, everything works fine, only some flickering when it runs on 87MHz..
But the battery life is quite good as it lasts for 2 to 3 days (light to medium usage, some texts, some phone calls, seldom Wifi)..
I have to say that the stock battery lasts much less then the one I got from Brando.. although the amperage is the same
I finally use xcpuscalar only for conserving battery, not for overclock. In another threads some people suffering from spotted, patched even broken LCDs and I do not take the risk to overclock Elfin because of possible overheat of the CPU and the CPU is most likely very close to the LCD due to the thinness of the Elfin. If the CPU is hotter overclocked than it is on normal speed it could cause spot, patch or even damage on LCD. This is my opinion.
Xcpuscalar is able to downgrade dynamically the CPU speed against Batterystatus which is only able to set one speed for the CPU, that's why I chosen xcpuscalar.
It seems to work fine even after soft reset... but 87MHz is very slow for me... it speeds up very sluggish. I use 169, 182 and 195MHz settings.
Will see the energy spare on the battery.
My HD2 is running at around 20% CPU usage when idle according to BATTClock. This is even after a hard reset with just Batclock installed, no radios on, and HTC Sense shutdown (just on old Windows today screen). Is this normal? No wonder the battery life is so short.
My Touch Pro generally shows 1-2% CPU usage when idle even with phone and push email on.
Task manager doesn't show any processes or application using that amount of CPU. Is it just Battclock that is wrong or is something else going on? I have turned off all location services.
Nick
Interesting fact. Needs more research though...
I've tried everything I can think of, including switching off automatic backlight sensing, location settings, etc. and Battclock still shows around 20% with nothing running. Any ideas for a more sophisticated tool to monitor the CPU? Does anyone else with Battclock installed notice this?
And if battclokck use 20% of cpu ?

BattClock itself does use almost no CPU. But HD2 has the ability to lower the CPU speed. I use a Microsoft API to get the idle percentage. Apparently this Microsoft API does not correct for the CPU frequence change?
You can check with a Task Manager, which process consume how much CPU, like FdcSoft TaskMgr. Then you can also check if BattClock is wrong.
I am planning to add another method for measuring the CPU spent, so for now you can better first check if BattClock is right or not. I have a Touch Diamond and there the CPU percentage is reported the same as the Task Manager.
WEll, mine is 56% atm and i have no idea why.
the only reason i can think of is g-alarm and messenger live
On a device that changes the CPU clock to meet demands, CPU percentage means nothing if you don't have a way to know at the same time what the current clock is.
And yes, Battclock itself might not use a lot of CPU, but it seems its way to draw itself on top of the menu bar is not very efficient. A bit flaky, the redraws are not clean, and I wouldn't be surprised if the system calls it uses do use a lot of CPU.

The Qualcomm CPU, the one the HD2 has, reduces it's clock speed when it is not needed to run at full capacity to save battery life.
i.e. If the CPU is running at 1Ghz, and a program is using 1%, it will drop the clock speed (due to lack of activity). Say it then drops to 100Mhz, it will then be running at 10% of the CPU clock speed.
A simple way to check wether battclock influences the readings somehow (which I don't really believe) would be to turn it off and check, as zuinigerijder said, with fdcsoft advanced taskmanager.
BTW I also get ~20% usage when idle, in some manila interfaces I get to lowest values of 7%, but then back to ~15% and then again ~20%
No way to know the current clock of the cpu?

I think you've hit the nail on the head. When I start a new program the CPU% drops briefly to 1-2% before climbing again. I guess this is the device ramping the processor back up before launching the program, hence dropping idle usage from 10-20% of say 100Mhzto 1-2% of 1000MHz.

Extract ,power settings, from omnia 2,is it possible?Put it on htc hd2,in cab format,regulate the speed on the CPU and save the battery life?Anyone?
i'm playing with different rom
at the moment i have discarded all the rom that give me problem (even if some of theme was very goood!!)
now i have installed on SD -=MDJ FroYo HD v.4.6=- with different kernel.
very good...responsive..everything works (except automatic brigtness features)
my question is?
how can i understand if the power consumption is too much?
of course i will keep installed for few days and see if is compatible with my usage but i would like to know some "avarage" values in order to understand immediatly where i am.
Install CurrentWidget.
Set it to log the MA once every 10 minutes.
Normal usage varies anymore from 100 to 350ma, depending on what you're doing. I believe it might be higher if you're using the camera.
Standby should be as low as 1 ma to 5ma with wifi and bluetooth turned off.
arghh in stand by it almost impossible to have less then 5mA...im using Battery Monitor app and it's normally 5mA stable with very minor increase.
i will see on the real use if it's work or not.
First - let me state - and it is true - that I used the search function.
I read pages and pages of advices to lower battery consumption on my HD2 Android... without success...
First I used an SD ROM. I read that a NAND would improve battery life. So this is what I did.
I am also using SetCPU with a profile when battery <30% and another one when screen is off to LOWER the CPU speed. In normal use, I set CPU speed at 768MHz trying to lower power consumption...
I use a task killer to free memory and prevent silly programs to drain my battery off...
I use Juice Defender to control wifi, data, etc...
And with all of this in place, my "Current widget" shows a consumption of 180mA with screen on doing nothing, up to 350-400-500!!! mA when acutally using the phone wifi+sync...
In the forum I read consumption like 3 mA - 9 mA!!! This is FAAAAAR Way lower than what I ever had with different builds...
So this is an help scream to everybody: what is your battery drain, and why mine is sooo High???
Hint: I am also a fan of LCD Density changer, with setting at 165... can this have an influence on battery drain??? I reverted to the original 240, doesn't seem to have any influence...
Thanks for your help,
Looki
My drain is 3-9 ma in STANDBY ONLY now and again slightly more but mainly the values stated. And my screen on between 120+160ma. Turn off auto brightness if you have it on, and set it at the lowest your comfortable with (display is big batt drainer) I DONT use taskillers as they do more harm than good. I use NO undervolting and only the default settings with my rom. I have low lcd density setting 167 i think. Lcd density has no effect on your battery drain!
Found this here. http://forum.xda-developers.com/showpost.php?p=13151738&postcount=11296 Might be of some use to you? (from hyperdroid gbx thread)
Whats youre rom?
And do u use ext partition on sd?
I dont even use SetCpu anymore. Only taskkiller.
Auto-brightness is on
Auto sync is off.
Im using UD 3.3 nand from crawlingcity
Stansby is 3 -6 ma
Using round 160 to 250.

How long does your battery last from 100% to self shut down? As for Current Widget, keep in mind that when people say "Standby", its generally referring to the screen being off. Set current widget to update every 30 seconds, and turn the screen of for 40 seconds. Then quickly turn the screen on, unlock, and check what it is reading then.
If its still high, try "Force Stop" applications in the Settings > Applications menu one by one, i've had to do this more than once to locate problem apps that were destroying my battery in standby mode.
I'm knew to Android, let me share you my idea.
I use UD3.3
I removed google stuff
gmail, search, etc
No auto sync
Location off
Always kill market when screen off.
I use beautiful widget for weather manual refresh.
I use battery widget
Auto level for screen
sometimes WIFI on
2g Only
2 or 3 calls,total of 3 to 4 min a day
My battery stay 48 hrs in STBY mode.
I think the most draining factor is
1) google stuff they are battery hog.
2) screen
3) bad written programs (every time they check connection to
internet or looping for doing something, looping will make
CPU in high frequency).
4) bad device driver such as BT which is known as 60ma
drain. it is not the hardware but it is the software doing
the drain.
thanks

Just one simple question. When phone is in deep sleep, the cpu's running speed is the min frequency I choose from the cpu settings or a default lower one?
I use smart ass 2 with min at 768 and max at 1516 . So in deep sleep my phone is running at 768?
Thanks in advance...

Not 100% sure but freq is minimum as it can be. And if cpu is not used no metter is freq 10000MHZ or 300Mhz it uses almost the same power. But when cpu is in use freq is important to power usage. Freq management is good not because it lowers freq but because it lets use lower freq on things that is not require hi freq. so it saves LITTLE LITTLE BIT of power. In idle mode (deep sleep) no meter what freq is.
But i still don't understand the need of governor. It's good only in cases where you overclock cpu but if don't - i don't see why it should be used.
PS Use app called CPU SPY it shows on what freq your cpu is being used and how much of the time.
Thanks! I use CPU SPY and it says tha about 60% or more is in deep sleep, 15%-25% is at 768 and the rest higher, which seems to be a good thing. But my phone still lasts for about 10-15 hours with normal use.
So i thought that maybe my min 768 frequency drain a lot of battery.
To clear things up a bit I use latest oxigen rom+latest franco kernel+zram+Juwe ram script...
Actually deep-sleep state is a special state supported by your phone MCU. In this state, a lot of functionality (therefore a lot of logical gates) are disabled thus MCU consumes very low power compared to normal functioning states. The thing about a CPU/MCU is when it is running even if there are no work to do no code to process, it has to run some command. While idle it must run NOOP (no-operand / no operation) command or do something equally unnecessary like counting a not required number. But in deep sleep mode, MCU actually stops working except for core functions to keep your phone going on.
Think about it this way, in a normal working state, CPUs most basic functionality is to read a command from memory, execute it and proceed to the next command to continue. Thus, in an operating system or a single purpose embedded software, CPU/MCU has to execute a "do nothing" command when you have no job to give it. But even a "do nothing" command need all of the MCU/CPU resources to be kept readily available. If you're sure that you have absolutely no job for your MCU/CPU to do, what you can do is to tell it to go and sleep fr a while until you wake it up again. In sleep, MCU/CPU can shut down a lot of its support systems like math processing, external memory access, graphics related functions (if any), even IO outputs. Depending on your CPU/MCU, this means until an interrupt occurs or a special sub system wakes it up, most of the sub-systems within your MCU/CPU thus may be millions of transistors will not be working so, your CPU/MCU will not consume as much power.
In layman's terms, deep-sleep state is a special state that shut down most of your MCU in your phone, thus while crippling it by removing its ability to function, making sure that it doesn't consumes much power. So OS (Android) (with the help of some additional hardware) controls when your MCU will sleep and under what circumstances it will wake. So it shuts down the engine -so to speak- when you're not using it for long terms and saving fuel rather than leaving your car on idle.
Hope this helps..
Thanks t_d_z. That is also how I imagined things...
But what is wrong with my battery which today, for example, went 33% down in 5 hours with 68% (from cpu spy) in deep sleep, without wi-fi on.
As i said above, I use latest oxigen rom+latest franco kernel+zram+Juwe ram script+smarass2 governor...
I also calibrated my battery by wiping battery stats, like i read in a post.
I have read in an other forum that if you use smartass (I use smartass2) or ondemand (I think...) governors, the governor is learning your habits and after a week you see the difference. Is that true?
Finally, can you guys who have "good" battery life, post your settings? (By settings I mean: rom, kernel, governor with cpu parameters, how you use the phone and everything else you think is important).
Thanks again...
I get about two days of battery life. I use Oxygen without any modifications. CPU is min. 245 (or something like that with 200, I dunno now) and max. is 800. Wifi is always on when I am home.
Try installing Oxygen-r1 and use it with a full battery, do not change anything and do not install too many apps. There will be apps that just won't stop running (like BBC or CNN app), I do not install those. Then you will see how long your battery lasts. If you just write some messages throughout the day and call somebody for 1-3 hours you should get about 2 days.
Then install your apps and test it again - maybe your apps are the problem.

Look not at cpu spy but in battery usage to find out what drains your battery. And i can tell All roms are kinda lame in terms of battery, except CM7. In deep sleep it takes about 7% of battery in 10hours. I tried all roms but non of them was so efficient. But latest franco kernel (which i think even more improves cm7 rom) does not support cm7 right now, so i've attached older version if you would like to test cm7+franco kernel.
With normal usage of 50 sms and 30minutes of calls and sometimes wi-fi to download few apps and 20minutes on easy games my battery lats about 18hours. Whan only sms it lasts 30hours. depends how long lcd is on
Well, I'm not an expert on smart phone OSes but I'm an expert on embedded systems and micro controllers. If the designers are not really stupid (which I'm sure they are not) all the peripherals gets suspended when the main CPU goes to deep sleep mode. So, it is almost impossible for the phone to consume much power in deep sleep state. Most likely your phone consumes that power the rest of the time when it is not in sleep mode. I agree with Tommixoft, you should use battery usage info rather than CPU spy to find what drains your battery. Also, here is a quick check list about what consumes power :
1. Screen, especially when it is brightly lit
2. GSM network (Even when you're not talking to phone, GPRS/Edge/3G network communications drains almost as much power)
3. Wireless network
4. GPS
As an additional note, if your phone is not going to sleep mode regularly try to uninstall applications that have "prevent phone from sleeping" security setting.
Hope this helps, and of course there are a lot of more experienced people in the forum that knows about the details of the kernel so they might provide additional info.

Oh I forgot to tell the MOST important thing, 768MHz is way too high a value to set as minimal frequency. Try to set it 245. I use 122 MHz and it work pretty well. Don't forget, when you need the CPU power, the governor will provide it for you.
