I have a Telus HTC Touch Diamond.

I am using stock ROM and am having battery issues as well.

I have GPS turned off (this is a battery drain), have bluetooth on and only turn data on when needed (I do not have weather app set to update automatically). I also have screen set to low for backlight and have settings to have backlight turned off at 2 min of non use.

I use data about 3 hours per day, do not have push email turned on and am at 15% to 20% battery life after 8 hours.

My EVDO signal is 2 to 3 bars most of the time since I am indoors at my office.

My concern is that the carriers and HTC keep saying there is no battery issue, Apple did the same thing until their 2.1 ROM and that increased battery life by 40% for iPhone 3G users.

I do also feel the device getting hot, I am still trying to understand what is really draining the battery, is it the interface, other software is does HTC use crappy batteries.

I had same issue with HTC Touch, after I purchased a Sendio 1500 Ma battery for Touch, I could get 8 hours of data with push email on and bluetooth on and still have battery to spare.

I have suggested to HTC numerous times that can not be so blind as to blow this issue of and the device battery life is fine.

If you think of this issue for someone who is deploying this type of device (more likely the PRO model) in a business, business people will not put up with less than a business day on a battery charge using push email and likely making 1 to 2 hours of phone calls.

I am guessing either the carriers and HTC are not getting enough calls complaining or are aware of this issue and just are not providing the information to front line people in customer service, I hope it is the latter and HTC engineering are working on resolution.

In my case, Telus Mobility has a Loyality & Retention team that called me to follow up on the device, they ended up providing a credit of $10/month for remaining months on my contract.

I hope HTC has a new ROM or someone creates a cooked ROM that improves the battery life.
