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.
