[EVO 4G Android Development] jasonziter:
Wow is all I can say.

So I had to report this to you all,

I unplugged my EVO at 6:15 AM after putting on the charger at 11p with 85% at the time I put it on the charger. So far I have used:

1. 3 hours of music....airplane mode on during this

2. 20 min of phone call use

3. 5 total hours of awake time:

a. Sending several texts

b. Checking email

c. Random daily market checks for updates

d. Random fooling around with the phone

83% Battery remaining.

That means as of right now (5:45 pm) the phone has been off charge for 10+ hours with 17% drain.

Amazing......Hell yes.

How am I doing this?

1. Build 131 of this kernal

2. XDA super power application

3. Power Manager (from market place)

4. Set CPU.

5. Stock Power Control Widget

6. No task killer or killing by me (i know which apps drain and i just dont use em)

I will tell you my settings / hardware / ROM.

PHONE

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

1. Hardware 002

2. Newest build of 2.2 Sense (3.70.651)

3. Baseband 2.15.00.09.01

4. PRI 1.77_03

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

XDA Super Power Settings

1. Root features - Only checked (that aren't grayed out) Delay service Start to allow root to be available after boot

2. Screen State - All checked (that aren't grayed out) , Delay action for 30 seconds

3. Wifi Network - All checked (that aren't grayed out), two minute disable delay.

4. WiMAX Network - All checked (that aren't grayed out), 30 second delay

5. Background and Sync - Only unchecked control auto sync - I do this because you have no control over auto sync and it keeps it enabled all the time if you don't uncheck this (IMPORTANT IF YOU USE POWER BAR WIDGET).

6. Lockscreen - All unchecked

7. When Downloading - Your choice (I have 3 Kb/sec for both checked)

8. Application specific - Nothing checked here

9. Tethering - Nothing checked here

10. Schedule Data - Frequency = never, Amount of time 1 min (its lowest)

11. Night Mode - everything checked EXCEPT Airplane mode

12. Low Battery - Nothing checked (power manager does this for me)

13. Charging State - All checked except do not disable wimax (no 4 g in my area)

14. Notifications - All checked - i just need to know

15. Debug - nothing checked

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

Power Manager - used mainly to control screen brightness

4 profiles

1. Battery powered - display, brightness 60, screen timeout 2 min, all others set to do not change (because I manually change them on the power bar widget)

2. Low battery - Display 40, screen timeout 30 sec, all others set to do not change

3. AC powered - Brightness 170, Timeout Never (for my car charger / mount)

4. Computer powered - Brightness 170, Timeout 10 min

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

Set CPU - Set at boot

Scaling = smartass (obviously when screen is on)

Max : 921600

MIN : 245000

ONE PROFILE enabled without notification

Screen off - Max 245000, MIN 245000, Scaling Power Saver (NOT SMART ASS - if set to smart ass it drains noticeably quicker for me).

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

Last BUT NOT LEAST

Stock Power Control Widget - Everything off unless I need it

Why update email until you really need read it plus we all know push destroys the battery life.

I hope these help. I know its confusing to set up, but once you do its INSANE and works REALLY WELL.

To Sum up:

At this point:

Stock 1500 mAh battery

20% decrease after now 12 hours = 60 hours approx at current use until charge needed (THATS TWO AND A HALF DAYS !!!)
