[Desire General] th3:
Here's the data I collected. Minimizing and changing usage for a full day was difficult for me since I depend on this device much, so I took a day our for it.

* Custom static wallpaper chosen from the national geographic range. Screens full with widgets and apps organized under drawers using apps organizer.

* Set to 2G (3G rarely if ever picks up in my house), still always at 0-1 bars, mobile data off, always data on disabled, GPS disabled, autorotate disabled, brightness 0%, sounds disabled, vibration on for all, auto sync off, background data on, 3* gmail and 7* mail accounts, stay awake set to 1min, location disabled. These remain as so except where otherwise stated.

* Many many widgets running on the screens, all full, incl., 4* extended controls, 7* switch pro, 1* recordoid, 1* gmail voice, 1* torch level 1, 1* HTC mobile data toggle, 1* application voice search, 1* lock toggle, 1* call log widget, 1* audiomanager, 1* stocks, 1* news, 1* bookmarks, 1* calendar, 1* weather and time, 1* 3G watchdog, 1* brightness level, 1* battery life widget and 1* mini info. Those I can control are set to manual update but others, usually every 5 mins.

* Notification icons are 1* SeePU, 1* Testing and 1* Battery.

* I have more than 140 apps installed, too many to list incl. Home++, Swype, Better Keyboard, HTC_IME keyboard/voice search, xScope, HelixLauncher2, Dolphin HD, Droidbox, etc. I'm a heavy multi-tasker.

* Background apps with high polling which provide usage everywhere incl. gesture search, call meter ng, apps organizer, app usage monitor, call confirm, call button (press search button long and the voice search or call options come up on any screen), missed call, netcounter, 3G watchdog, total recall, appbrain market sync, sms popup, bar control, system monitor log, clipbot, extended TTS and translate. I think that's all.

22:15 - Took it off charge at 100%, WiFi on at 2 bars, GSM on at 0 bars mostly but at 1 at times, the rest as usual (as mentioned above). Ran 2* Speedtest through the app. Then went online, read 9 sites, about 15 threads fully at various sites, refreshed and read xda Desire section through the app, messaged two friends through fring for 9 mins total, replied (lengthy replies) to 3 threads online. Downloaded/viewed 3* small images (graphs) and 4* PDFs in that time. Read 2* PDFs in PDF View. Made 2* calendar notes. Set brightness to 17%, headphones in, then watched 19* YouTube vids through the app (HD) till 23:55.

23:55 - Received two prank calls from unknown weird women (5min total), sent 3*2 messages to friends, received 6 replies, then another prank call -> set to airplane mode (WiFi still on). Saw a fire 300m outside our property from our rest house, took 4* pics using the phones camera. Used net to sync and update every mail/widget account (incl 6* place weather and 13* stocks) and read/replied to all their data, which took long. Spam mails were 233 alone to one account. Updated 31 accounts in NewsRoom, most with plus 18 feeds and read them, 4* online, starred 5*. Dolphin HD and Chrome were both used interchangeably with 7 bookmarks added. Opened GMaps and browsed that and Streetview for 13mins. Then me and the better one watched a 9min 2500Kbps 800*480 vid in Act 1 player followed by the last 14mins of a 950MB 800Kbps movie on the SD card.

01:15 - Ran a quadrant benchmark and then listened to 4* MP3 repeatedly for 11mins using the app 3 (headphones, 4th level vol). Made a 2min voice recording through Recordoid and browsed 8* photos. Backed up 13 apps in AppMonster, uninstalled 3* apps, updated 7* apps through the market, received the no SD card error, remounted thrice -> had to restart the phone and continue.

During all that above period, in between, there were extra quick uses. The torch widget was used for 10-40sec intervals 9*, the LED Desire light app at 80% 2* for 8secs, Compass 1* for 1.3 mins, NoteMe for 40-250secs 5-6*, Astro 11*, Kreac calc 2*, TaskPanel 3*, ConvertPad 2*, Kaloer clock 1*, Androzip 1*, WiFi analyzer 1*, System app 2*, Ultimate Stopwatch 1* for 2mins, Gesture search 2*, Earthquake app 1* for 4.7mins and Quick App Clean Cache 2*.

01:55- Switched WiFi off at 01:55 whilst reading a NewsRoom Engadget report, whereafter, I only remember looking at the screen once. Fast asleep.

04:20 - The eye awoke, so I checked some important mail fully that I had already downloaded but not read properly. Also read 3* NewsRoom starred reports. For a total of around 12mins, and then went back to sleep.

05:20 - Couldn't sleep, came down to check on the beautiful one who appeared in the rest house watching the fire crew. WiFi still on, enabled GSM for 5mins, received SMS, read, replied -> set to airplane mode. Linked phone through USB to laptop as a Disk drive, sync'd Droidbox by removing 3* 40MB files through the phone meanwhile transferring a 980MB movie to the phone.

05:30 - Watched 2* +2.4Mbps vids on the phone for 16.7mins in Act 1 player with brightness at 17%, vol at level 4. Then started watching the just transferred lengthy movie at 750Kbps uptil 08:50. Quite a few pause and rewinds in there but it was watched non-stop.

08:55 - Updated all mail/widgets, 4* NewsRoom feeds, read the important ones. Read a few threads at xda forum through the app, and 4* threads at other sites through Chrome. Then started up the YouTube app and watched MJ related vids (many repeats) till 10:20 in HD. Basically the Thriller vids. WiFi is still on, in airplane mode, but the phone is in standby thereafter.

10:50 - I leave for some business outside. Battery is now at 20%. Left in standby with WiFi on at home.

18:45 - Came home and checked the phone expecting it dead but it was at 19%, much to my surprise. WiFi on, GSM on, non-stop internet, YouTube, xda forum app, NewsRoom and Act 1 player use from then onwards. 5* YouTube vids, 23* emails, 1* miscall, 2* 24min total 2.5Mbps vid playback and many other net related uses from here onwards.

20:45 - Whilst loading a SPCR thread, the battery hit 0% and the phone shutdown. So not even 24 hours under heavy loads but more than good enough for me.

*Vid/aud bitrate is crucial as higher bitrate equals higher CPU usage and hence lower battery life.

* System monitor log showed that my CPU spent most of its time at 298-380MHz. Ambient temperature at night was 28 degrees but 32 degrees during the day (CPUs/chips draw more power the hotter they are and vice versa).

Yes... if you've followed me fully here, you'll notice I seem to be one of those getting the 'better' battery life, heh :)

It was a pain to keep proper track of all this. Total pain. Hope it helps.
