Optimizing battery life

After using Cyanogenmod 7.03 (stable) custom rom, I've noticed that battery life isn't so gorgeous. Decided to tweak battery duration as high as possible. R&D process started from XDA dev forums. After few hours research, founded two tips:

1. Calibrate battery via Battery Calibration app (removes batterystats.bin and creates new one), highly recommended to proceed after installing custom rom
2. Install custom kernel, which allows to optimized governor (aims to provide ample performance for responsiveness while keeping power consumption in check)

I installed following custom kernel: http://forum.xda-developers.com/showthread.php?t=1180071

Battery calibration app can be found from here: https://market.android.com/details?id=com.nema.batterycalibration

Protip! Custom kernel (.zip) must install as custom rom. Full wipe is recommended but not obligatory. If custom kernel doesn't work properly, re-install with full wipe.

REMEMBER BACKUPS VIA NANDROID!

Rooting Desire Z

After deciding not to wait official Gingerbread release via OTA, I followed root instructions from XDA developers' forum (found here: http://tinyurl.com/zeta-root ). Instructions had several steps and required few softwares and additional files to download. Main root process structure was following:

Required:

1. Temp root via ADB.
2. Downgrade to stock RUU (RUU_Vision_HTC_WWE_1.34.405.5).
3. Perm root via ADB (Clockworkmod, SuperCID, secu-flag off & an Unlocked HBOOT-ENG).

Optional:

4. Install custom ROM (Cyanogenmod Stable 7, 7.03 Vision signed)

Whole process took around one hour (including earlier mentioned required file downloading and installation).

Even though I was beginner with Android tweaking, I succeeded instead of bricking my DZ.
