Thread: HTC ChaCha battery life less than 6 hours - Dialler component uses 49% of battery

The battery life on HTC ChaCha is appalling, less than 6 hours of moderate usage.
Wifi, GPS, bluetooth disabled.

If I look a battery usage is shows the Dialler component uses 49% of battery after receiving a call.
A quick internet search shows a lot of HTC Gingerbread (OS2.3.3) users are experiencing the same problem.

I have tired some of the recommendations:
In Settings -> Sound -> Disable Quiet ring on pickup, pocket mode and flip for speaker.
Enable & or disable - Blue tooth
Install software OTA update 1.18.401.1
And I still have the problem. I have reproted to HTC today.
