1. Changing the poll interval is ok but I wonder if this is the timing for the battery monitor and display of battery %. Most tweaks I've seen set this to 25000. To each his/her own.
2. The Power and Performance cab sets the following:
HKEY_LOCAL_MACHINE\Comm\AsyncMac1\Parms
HKEY_LOCAL_MACHINE\Comm\Irsir1\Parms
HKEY_LOCAL_MACHINE\Comm\PPTP1\Parms
HKEY_LOCAL_MACHINE\Comm\L2TP1\Parms

DisablePowerManagement to Zero (0)

The Irsir1 we don't have. (Infrared)

It also makes the following changes to the registry to boost performance:
HKLM\SYSTEM\GDI\GLYPHCACHE
<parm name="limit" value="32768" datatype="integer" />
HKLM\SYSTEM\StorageManager\FATFS
<parm name="CacheSize" value="4096" datatype="integer" />
HKLM\SYSTEM\StorageManager\Filters\fsreplxfilt
<parm name="ReplStoreCacheSize" value="4096" datatype="integer" />

Glyphcache modification may already be done. Depends on the chef.
FATFS modification is most likely already incorporated.
We don't have fsreplxfilt. I don't know the reprecussions of adding it to the registry.

So, If you install the cab you are only getting the increased Glyphcache and increased FATFS cachesize if you also change all of the DisablePowerManagement to zero (0) except the SIM.

3. Phone as Modem has two settings in the registry. AlwaysOn and Enabled. Mine is default set to AlwaysOn=0, Enabled=1. This leads me to believe that unless you tether there will be no power consumption from the device.

4. A dormant data connection consumes no power so disconnecting the data connection will actually INCREASE your power consumption by reconnecting each time the device needs it. Tested it, trust me.

5. As for the battery charging procedure. I was talking with a Sprint tech the other day and he showed me the charging board on my phone. It is separate from the rest of the boards on the phone and he DID say that there is some logic in the charging module to detect and remember the battery stats on a fully charged battery. This leads me to believe that you may be on to something with this. He wasn't happy that HTC shipped the phones with a partially charged battery and this may have caused a lot of the crappy battery performance issues on this phone. I'm gonna try this tonight.

So, here's what I recommend as OTHER battery tweaks.
INSTALL LUMOS!
The WM backlight control is lousy. Lumos is way better. You will be surprised how much better. Backlighting, as you pointed out drains the battery quicker than any other thing on the device. And, don't worry about your data being always connected.

VERY NICE! I like the break down of the tweaks I mentioned. Helps me understand more of what the tweaks do and whats really needed and not needed. All I know is that the tweaks I mentioned were the ones that I did and it is now 1230 and I am just now dropping to 50 percent on my battery. I was not too sure what was helping the battery or not helping. I just did as much as i could to prolong the life. And as far as setting the poll interval to 30000 I noticed that the battery seems more accurate and cool. Where as 5000 was making my phone really hot without even using it. 20000 made my phone warm without using it. 25000 was very decent but I could feel a little heat in my pocket when not using but not much, almost to none but felt some, and 30000 has been almost ice cold with the phone just sitting in my pocket. I guess like you say it is to his/her own. I just prefer 30000 just for the simple fact that the phone is very cold when not in use unlike the other intervals that made my phone heat up. The data disconnect was because when I would do something like a prl update or just something as simple as checking my facebook, when I would disconnect from the page, the data would stay running. I would check the notifications tab and I would see data still running. 12 minutes one time and I was highly upset because my battery that was once at 93 percent was down to 79 percent within minutes. That was the reason for the disconnect after 1 min. If there is another way to stop the data from running continuously without disconnecting it after a period of time would be greatly appreciated.

Also Im downloading and installing LUMOS! I will see how much this will help out the already prolonged battery life! Thanks!
