@steven I can't thank you enough! I've been vexed with this problem too. I use another email app, but of course, Gmail was always there in the background. At the very least, I've identified the problem with my phone and can do a quick fix when it rears its ugly head again. Thank you, sir!

Nice article!
Just wanted to point out that there is a very powerful (recently improved) battery manager app in the Android market called JuiceDefender, which can do all the micro-tweaking on auto allowing a much more energy-efficient usage of the phone.

Simply put, JuiceDefender intelligently manages some of the most battery-draining components (GPS, WiFi, etc.), powering them only when they are actually needed ...rather than leaving them on all the time. And it does much more than that, it's literally full packed with features for battery consumption optimization (connectivity scheduling, location-aware controls, battery threshold controls, etc.). It's quite amazing what it can do.

JuiceDefender is free, fully customizable and fully automatic, meaning that it only needs to be set up once, and then it runs by itself improving battery life from behind the scene - you won't need to touch it again!

You can find some video reviews on JuiceDefender’s Facebook page and more info on its website.
Hope that helps!

Useful information. I need it dumbed down further. Where on the htc Android do I go to access the email settings? Also, does having a shorter/longer power off period make a difference to battery life?

You can try to disable 3G (WCDMA) and keep to 2G (GSM) by default, you will have lot more of battery life.

On a Samsung galaxy S, after froyo 2.2 upgrade, the linux throttling is activated, at full frequency I have about 1000 bogomips, and at low frequency (automatic when no cpu task is running), 200 bogomips, the frequency is no more displayed in 2.2 (they perhaps are afraid that customer complain about a 100 or 200 Mhz CPU instead of a 1Ghz CPU), but I seen in /sys parameters that conservative mode is used and can go down to 100 Mhz :
$ cat /sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_max_freq
1000000
$ cat /sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_min_freq
100000
$ cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_available_governors
ondemand userspace powersave conservative performance
$ cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
conservative
