Diamond Heating Issues Explained?

Battery Life + Heat Problems on Sprint Diamond?
Battery life issue on the diamond is due to the radio in constant refresh, basically instead of interval of 300ms the diamond was set to 100ms and causes battery drain. The heat issue is also another cause but the reason for the heat is due to the heat plate was not added to the sprint version behind the keys like it was supposed to and sprint and HTC are discussing that.
...the heat plate is on the Pro, also I tested the phone and over clocked the processor to test to see if there was a heat issue, there was not a problem at all, and the processor took the over clock nicely. I tested the radio also for the heat issue and after 2.2 hours it was warm to were it could be noticed but correct me if I'm wrong what phone doesn't get warm with that amount of talk time.
So they left this heat plate out of the Diamond and cranked up the radio refresh which killed the battery faster and heated up the phone when ANY radio is in use? They did this AFTER adding the larger battery?

if this IS true, i wonder what HTC/Sprint will do about the existing diamond customers?

Short Term: I flashed my phone to the VZW radio(which consumes less power and therefore demands less from the battery).

Long Term: I expect to see a recall that'll include a new ROM from Sprint, new back cover to the phone with more heat shielding built right in, or just an even swap for a "new" batch of Touch Diamonds.

in a perfect idealists world, yes, in a realist world, i wouldnt expect sprint to do this!!

I would, simply because this is a heat issue.

the heat shields is missing. FCC said it wasn't required at first. it is. i believe replacement units will have it.

VZW radio helps allot.

i would like to know how to fix this f'in radio refresh so we can save so juice.

agreed, hopefully, there will be some type of recall or silent recall so we can swap our toasters out for shiny new diamonds.

maybe, i dont know if Canada will get new swapped devices.

I wouldn't be too worried about Telus, they're usually good about stuff like this too

I asked the OP who posted the information about refresh and heat shield on the possibility of setting changes to fix the 100ms vs. 300ms., he did not answer. So I'm asking again:

- If there were any other questions please post them again, my apologies for missing any.
In the "other", now defunct thread, you posted that the reason that the Diamond is murder on battery is because the radio refresh is set to 100ms and it should have been 300ms, and that a ROM update could correct this.

1) Can this be fixed without a ROM update? I looked in the registry and all of the items/menus in EPST but couldn't find anything close to the 100ms value.

2) The only "refresh" or polling value that I'm aware of is the "slot cycle index". The slot cycle index for Sprint Diamond is set at 2. The forumla for calculating paging channel time is 2^N x 1.28 (where "N" is the slot cycle index). This puts the time at 5.12 seconds (or 5120ms). How is the "radio refresh you mentioned relate (if at all) to this?

I'm a Diamond owner intending to go to Touch Pro, but help here can ease the pain of waiting for the Pro, as I am hoping for at least 24 hours on a charge on the Diamond.

3) Is it true then, since HTC and its affiliates are aware of the incorrect setting on the Diamond, that the Touch Pro will be released with the correct setting and will have BETTER battery life than the Diamond?

Thank you.

On the subject of heat-shield: I can't see how the reportedly omitted shield could hurt the battery life. If anything, NOT having a shield and feeling the heat on the outside means that the heat is radiating out and dissipating, which can HELP battery life (lower internal temp). In general, higher temp=higher resistance=more power needed to drive the circuit. This is why superconductors need to operate at very low temps. Unless there is something I'm not seeing, I can live with the heat and would chose to go without the shield.
