You could if you didn't use your phone. Look at his stats. Display barely comes into it. That's because he isn't using the display, ergo not really using the phone.
There are so many things you can tweak to be more efficient and use less power. Display us one thing you can't tweak. Brightness makes a little difference but after that, nothing.

So you're getting 20-3hrs then? Sounds reasonable to me. If you want better then turn everything to manual sync, don't text anyone, don't call anyone and move into a tent next to a phone mast.

To be honest, if he has an undervolted kernel and we already know the screen is off. Set CPU to set 245mHz max screen off profile with powersave governor, then its possible
Plus could have done the battery calibration trick which charges to about 105% or more, still reading 100

Coming from an i7500 I'm finding the battery life amazing! 
Five home screens, live wallpaper, tons of updating widgets and stuff, all syncs (except stocks lol) on and I'm a fairly heavy wordfeud player so it gets a fair bit of use It comes off charge at eight in the morning and about half midnight when I go to bed it's still got around 30% left :O Only a week old too so I expect improvement!
None of the above on the i7500 (except syncs, really no point if you don't) really limited gaming and browsing (partly 'cos it was a pain anyway) and there's no way it'd last that long. Hell, if I glanced at it it cost five percent
Some people in this thread need to be thankful for what they've got

I took my phone off the charger at 7:45 this morning when it was a 100% charged, it's 9:30 and I haven't even unlocked the screen until now and the battery is at 89%. No wireless connection is on. I love how random the Desire's battery use it.

Ah ok I didn't know that would be possible. Even if I crippled mine the cell would still eat a little battery.
But still, good to see another pointless battery post.
dan's right, my phone's screen is off most of the time i do play games on it, text, call, browse stuff, listen to music, etc (and pretty much use it as much as i want) but definitely most of the time the screen is off (work, sleep, living life). I'm personally very happy with my battery life. If i needed it to last longer i would adjust my settings accordingly.
i also do calibrate my battery, but most of the time i switch the phone off when it's charging when it gets to about 90% and then switch it off and let it charge the rest with the screen off. ALSO i do have custom kernel which undervolts to 245 when the screen is off (i have some other profiles set up in setcpu) but the governor is called 'smartass' (??) and it can easily go for several hours idle before dropping any % (even with auto sync on and 3g on)
anyway, i think the whole point is that once you understand how the phone consumes battery it's easy enough to adjust to it and still get as much as you want out of it.
edit:the circle battery thing is just a battery mod

I don't understand the need for an app to do what the Desire already does, at least with v2.2. According to a testing app I tried early on, the CPU drops to 245MHz automatically when idle, and ramps up as needed to 995MHz. Perhaps that explains why my battery life has always been just fine?
???
I don't think that's possible with a Li-Ion battery as the microchip in the pack will cut current flow to the pack when the battery is fully charged. Plugging in the charger within a few minutes of a full charge should do nothing to the battery pack regarding it's state of charge. The microchip is there to prevent overcharge, overvoltage, and overtemp. I think what the battery "trick" does is reset the calibration on the phone so it reads the battery at the correct voltage and charge state which explains why on some phones it charges the battery for a short while when the phone shows it's at 100%, and once the battery is fully charged, it resets the phone to show 100%, and deplete charge as the battery is used as it should.
When my phone is fully charged it shows 100% at 4197mV and doesn't drop to 99% for several hours if it's sitting idle. I consider that normal as the phone uses about 1% every 3-4 hours when idle. Overnight I only see 2-3% loss during a 7 hour sleep.

The screen off profile is min and max 245mhZ. Whilst the screen is off, the CPU doesn't ramp up at all. Also, the app is used for overlooking and using a governor different to the default om demand.
In regards to battery. When I do the "calibration" in use, my battery stays on 100% for much longer than on 99%. Why? No idea. But it does :$

Sounds similar to what happens when you fill your car with fuel - for the first 50 miles you use the fuel in the filler pipe and the guage stays at 'FULL'

Wow you only use your phone for 4 hours out of 44?
I've had mine on for 6.5hrs today and have its awake time is 1.5hrs. Battery is now at 66%, have used wifi for about 2 hrs this morning browsing internet, reading rss feeds. Then watched about 30 mins of youtube at lunch time, made a couple of calls.
I usually get to the end of the day and it needs to charge overnight, but i would consider myself a heavy user of the phone.

Yep, at least on that day. The screen was on for about 10% of the time (obviously the screen is off while i sleep, so that's roughly 15 hours of sleeping in that period
). Sync is always on, and so is 3g, so it's always notifying me of emails etc. the screen doesn't need to be on for the phone to be working for me
Sometimes I need to charge it at the end of the day too, but it's usually because i've used the gps to get somewhere, had an eventful day that required documentation (several photos & videos) or have played games on it for long periods (hours at a time).

i think the 'calibration' just makes sure the battery meter software is displaying the correct battery level, it doesn't actually extend the battery's capabilities. (although if the phone thinks it is below 15% it will start showing you low battery warnings, which would be annoying if the actual battery is above that 15% but the software thinks it's not)
afaik, it is recommended to calibrate the battery at least once whenever you change roms.
it caps the maximum at 245 when the screen is off (which is enough for it to sync and notify me of anything), so instead of ramping up to 948 to check my email it does it at 245 and takes the same amount of time. SetCPU can also set profiles, so for example it can automatically underclock to 500 max if you're battery is below say 20%... and it can also overclock if our rom is set up for it. It's a handy app, not essential, but definitely useful (if i needed to go 'survivor' style i could underclock the cpu to max out at 500, but if i wanna play a psx game i can overclock)
That is what my phone is at right now, 6.5 hours up time, almost 2 hours awake and I am at 58%. This is I have downloaded maybe 4-5 smaller application in the last hour.
Wow i feel good then, im getting over 21 hours on a charge..Ive calabrated the battery, i usually only have one bar if it isnt searching for service, and only turn 3g on when i need it. I keep wifi on and the backlight on low. So far so good, im impressed its doing better than my old blackberry.
~Hi guys I charge my battery overnight with the handset on. I usually wake during the night and see the green LED to indicate full charge. I then unplug and switch off my phone.
On some days when i switch the phone on when i wake up, the battery has ~90% charge, despite it being switched off since charging.
I assum the solution would be to switch the handset off before charging..

How very odd, the EXACT same thing happens to mine!
@tomhunter - Firstly, welcome to the forums! It's actually a great place to hang out. Must admit I had the same reaction as the first couple of replies when I saw this topic. This question gets asked every couple of days and it's been flogged beyond death.
Second, a couple of tips for making finding answers as easy as possible: as said above, when you type the title of a new topic you get a few suggestions of similar topics that already exist. It's well worth checking them out first, they usually have an answer. Also, take a moment to look through the most recent topics, maybe the first 2 or 3 pages. Again, chances are high that there's a topic similar to what you're interested in (and if not, then other random topics will always teach you something new!)
in response to the query, it was a simple case of the battery reaching full charge and draining back to 90% before starting all over again. i'm gona charge my fone whilst it is off in future, i enjoy the peace and quiet while in slumber.
With regards to my 'noob' status, i posted the thread in a hurry without looking around first. no harm done
