[HD2 Windows Mobile 6.5 ROM Development] ahennin4:
Settings 1.1

Standby ~ 3-6mA , peak ~150-2200 mA (Depending on real signal strength) Currentwidget app

Signal Strength: -63 dBm 25 asu

Now i did not create these setting for someone who is a gamer, or use of heavy graphic apps. I am not a "Gamer" on my phone, i use my phone for business, calls, emails, google voice, calendar, web browse, text, music, Maps, wifi Hotspot, & Facebook.

If you use the phone in a similar fashion as i use it for, then you can achieve close to the same battery life as me.

***Did not test with a Live wallpaper. I use a normal wallpaper.

Basic settings:

I have WiFI- OFF, Bluetooth-OFF, Brightness-LOW AS IT CAN GO (auto brightness-OFF), Forced into 2G mode- 3G mode can be turned on if need be, GPS-OFF, All Location Settings- OFF, Background data-OFF, Auto-Screen rotate-OFF, Display Animations-NONE, Screen Timeout- 30 SEC. System software update-OFF.

(Optional) Also if you want to completely turn off the data connection completely, so no unwanted data will run. HOLD the Red end button, then tap the option at the bottom "Mobile Network" (You will see the "E" or "3G" symbol go away and all you have are signal bars.) You can turn data on in the same fashion as need be. (This does conserve battery, and i have noticed that with doing this it makes little difference if you have WCDMA only (3G), GSM only(2G)) I tested it with GSM/WCDMA auto and I observed similar battery drain as with GSM only (2G)

(OPTIONAL, I didn't want these features so i deleted them) First off what i did was i deleted any account that was under the "Accounts & Sync" area such as:

Weather

News

Stocks

Blahh

Blahh

To where the only thing that was under there was my Gmail account.

Reason: because all these apps would auto run and then sip my juice.

How to: run the app ES File explorer

Go into

/System / app

and delete any file that looked like the apps i talked about above, (BUT be careful your deleting the correct one!)

(If your not sure about a file then don't delete it)

(DO THIS AT YOUR OWN RISK I'm not responsible for you deleting any files)

Then i proceeded to delete any apps that i did not like, (and that kept running in the background after force close)

Such as:

AIM

MSN Droid

Yahoo messenger

Twitter

Uninstall via

Settings > Applications > Manage > download

How to: Go to

/System / app

And delete them like you did before (if they appear in here, i can't remember)

Now if you re-boot your phone these apps will install themselves again!

Trick is:

You need to go to

/sd /Android/Applications Folder

and delete the .apk from there as well

--------------------------------------------------------------------------

Now as far as the SetCPU Settings

Open the App:

Autodetect your speeds.

Main Page:

Scaling: "Ondemand"

Check the box, "Set on Boot"

Profiles:

Check Enable box, and you can check the notifications box if you want to (i chose not to)

Add the following profiles:

Temp > 50.0 C *	499 MAX / 245 MIN

Priority: 100	ondemand

Screen off	245 MAX / 245 MIN

Priority 95	Ondemand

Charging/Full	729 MAX / 245 MIN

Priority 90	ondemand

Battery < 30%	460 MAX / 245 MIN

Priority 61	ondemand

Battery < 50%	576 MAX / 245 MIN

Priority 55	ondemand

Battery <100%	729 MAX / 245 MIN

Priority 0	ondemand

(MAKE SURE THAT ALL OF THE CHECKBOXES ARE CHECK MARKED AND "ON")

Advanced Tab:

(Very important steps!!!!)

Sampling Rate:	20000

Up Threshold	30

Ignore Nice	0

Powersave	0

Now click "Apply"

and check mark the box, "Set on boot"

-----------------------------------------------------------------------

This should cover about everything, there is still little tweaking to be done.

If you noticed we have underclocked the processor just a little, this small sacrifice of minimal performance will gain battery life.

At times you might experienced very minor lag (if any) with the performance changes.

Have not experienced ANY crashes or instability of any kind in the few days of me testing the settings.

I observed completely stable Android OS.

Benchmarks were only about 400 points in difference from stock, so i'm giving up little performance differences, for 2-4 times the battery life.

Keep in mind these settings can be undone by unchecking the "Profiles" under the Profiles tab under SetCPU, if you need a performance boost or something.

I hope this works as well for you as it did for me, Please thank SuperSport and cmylxgo for their hard and great work!!

Now you should be able to go 24-48 hours of battery.

If you like these settings please so kind to buy me an Iced Tea or two, it will be much appreciated!!

I will continue to work on making the HD2-Android and increasing battery life.

If there are any requests, comments, questions please feel free to reply or shoot me a PM

Please share your feedback using my Settings!!

Cheers, :)
