I noticed when running ARHD 2.1.3 that the battery drains quite fast than AOSP or AOKP roms.
How do you extend your battery life on battery life on sense roms?
If your phone is rooted, remove google **** (maps, contact sync, calendar sync, bookmark sync, search, picassa, Gmail, YouTube etc) and some HTC crap (htc hub, likes, message upload, smith, and some more) using a script to clean up the ROM. Disable autosync, disable backup & recover with Google, and most important: don't store personal data such as contacts, calendars & docs with Google. Disable background data, disable 'always on' internet, set WiFi sleep policy to 15 min, set screen animations to none, screen brightness to 25-30%, select powersave on, set powersave to kick in at 25% of power and set all email retrieve settings to manual.
