[HTC Inspire 4G] natethegreat12345:
First off I want to start by saying I’ve been a XDA member for 2 years now and have been very inactive with discussion on the forums, so I’d like to start by stepping up a bit haha.

After reading posts though out the roms (MIUI DEVELOPERS, Core Droid, Revolution, ClearDroid, RCMix, Leedroid, cyanogenmod 7, TPC stock, and others ive failed to mention) many users experience different feedback from their battery. Some have excellent battery life lasting over 20 hrs, while others need to start charging their phones in little as 10 hours. To try and figure out why feedback varies between users so much, I decided to make a battery usage benchmark to try and find some relationships between heavy battery usage and user preferences/settings. Comparing configurations and setting a benchmark could help out people with poor battery life.

I am currently running Android Revolution 3.3 by mike 1986 with recommended radio (12.41.60.19_26.06.04.14_M) and running under ATT network. Also using default kernel. I performed a full wipe of data/cache before flashing too. I have not flashed any side zips like the performance patch or audio fix. Battery has been fully calibrated.

Accounts- currently have synced:

•	Facebook – contacts along with notifications which is updated every 2 hours

•	Facebook for sense- contacts and live feed (every 2hrs)

•	Google- gmail, contacts

•	News- every 4hrs

•	Weather- every 3 hrs

Backround data and auto sync are both enabled.

Had calender synced under google but I noticed heavy usage coming from the app and decided to disable it. Facebook appeared to be syncing birthdays in the calendar. Having many friends on facebook, this meant many birthdays to be synced. The calendar app appeared to be heavy on the battery. Having disabled calendar sync seemed to improve battery a slightly. Also recommend staying away from HTC sense account for it is really heavy on the CPU and battery.

Wireless network-

Don’t really use wifi too much, only sometimes at school when reception is poor. Don’t use Bluetooth either. Network mode is set to auto.

Display-

•	Auto brightness

•	Screen timeout 30 secs

Location-

•	Wireless network location enabled

•	GPS is kept disabled until it is need for Google maps or something like that.

•	Phone finder is turned off

Apps-

•	Adfree

•	Adobe reader

•	Barcode scanner

•	Current widget

•	Facebook

•	Maps

•	Quickoffice

•	Rom manager

•	Setcpu

•	Spare parts

•	Speedtest

•	Supermanager

•	XDA app

I try to keep the apps on my phone to a minimum to reduce resource use and backround data.

Setcpu-

Main: min 230 MHz, max 1075MHz with ondemand scalling

Also have 3 profiles set up:

•	Screen off- priority 100, min 230 MHz, max 768MHz with conservative scalling

•	Battery< 10% priority 90, min 230 MHz, max 230 MHz with powersave scalling

•	Battery< 25% priority 80, min 230 MHz, max 537 MHz with ondemand scalling

Misc-

•	Don’t use live wallpaper

•	Moderate usage

o	20 talk time daily

o	Probably an hour of data usage combined daily (app downloads, internet browsing, facebook,youtube, etc.)

o	I do txt a lot, probably between 100 and 200 messages sent/received daily

•	Listen to maybe 10-20 minutes of music a day.

•	Powersaver at 15% battery life

With everything listed above, I get about 18-20 hours of battery life on a single charge. I am just trying to set up a benchmark for people with poor battery life to refer too. I hope this may be some help torwards people experiencing battery issues. If anyone has other suggestions or would like to post some of their configuration setting, feel free to post^^ thanks:)
