[Motorola Droid and Milestone General] deitiphobia:
Charity ROM has doubled my battery life! Fast as hell too.

Thank you for posting about Charity ROM. I was a long time user of Bugless Beast, then I switched to Cyanogen, and just spent a 3 or 4 days with the MIUI Rom.

I downloaded and installed Charity ROM yesterday, and I gotta say, I am blown away! :D

I installed Charity ROM with no more than 90% battery level. Running Chevy lowV 1.1Ghz kernel. I then left my phone unplugged all day while I did the following activities:

- After ROM was installed my phone had to download and sync all of my apps and google and facebook contacts. This all takes a while and is not insignificant to battery usage. (via WiFi).

-

- Angry Birds for 10 min

- Antigen (game) for 15 min

- Watched 4 you tube videos wich all totalled to about 12 min

- "Read the morning papers" aka...browsed the web 2 mornings for about 25 min each.

- Received and sent email, SMS, Google Talk and Google voice, all throughout the day.

- Listened to music during my commute wich was about 90 min total.

- Made a few brief voice calls totalling 10 - 15 min.

- Browsed the Web and Engadget app periodically throughout the day.

- My phone was ON all night.

I've made it to 18 hours and 24 minutes; and still going with red battery light blinking. I remind you this is with 90% or less of battery life to begin with. I've never had battery life this good with any other ROM...not even close!!! I usually get to about 8-9hrs if I'm lucky and that's from 100% charge. Many days I leave the house at 9 or 10 AM and I need to plug in my phone by 3 or 4 PM.

I have not been reliably able to make it through a work day for a very long time. I consider myself a heavy user. Many days I just don't use my phone so I know the battery will last a bit in the late afternoon early evening. Even so, It often dies in the mid evening even after light use during the day.

I used the developers recommended SetCPU profile settings:

-Screen Off 250max/250 min interactive - priority 100

-Charging/Full 1100max/250min interactive - priority 80

- Battery < 10% 400max / 250 min interactive - priority 70

- Battery < 20% 550 max / 250 min interactive - priority 60

- Temp > 49.5 degrees C / 400 max / 250 min interactive - priority 90

Usually if my battery is less than 40% charged, I will wake up in the morning with a dead phone if I don't plug it in. Somehow, Charity ROM is drastically better with Standby battery performance. That alone might make all the difference in the world.

I now have full confidence, that I can unplug my phone at 9AM and have a full day of moderate to heavy use of my phone, and I will absolutely make it through the work day. With moderate use, I will probably make the whole day. With light use, I think I could easily get two days out of this ROM. I'm conjecturing and extrapolating here, as I'm not about to not use my phone for 2 days to see how long it can go on standby and light use. I'm quite certain by yesterdays results, that this ROM kicks ass and is unique in that it is very fast and battery life kicks ass!!!

No general lag. No lag or delay for Launcher to appear when I press Home (I had this problem on Bugless Beast, Cyanogen and even MIUI Rom). I'm running it fully cranked at 1100mHz using Chevy Kernel. See Set CPU profile settings above.

MIUI Rom also has pretty good battery life in comparison to Cyanogen or Bugless Beast, but Charity Rom blows that away.

I don't know who this Developer is, or what kind of mojo he's working here, but I am sticking with this ROM. I miss some of the Cyanogen and MIUI mod customizations, like wifi and brightness controll from the notification bar. I will gladly trade those features for a doubling of my battery life.
