Hi all!
Regarding price. I found this pre-price at a swedish site:

6344 sek = 680€

Idle programs DO consume more power than completely closed programs  . When a program is idle, it is still using hardware resources albeit to a very much reduced extent. Eg: If my TyTn II is in idle with the usual background processes, it consumes 7maH, but if I close all the non critical proceses I can drop the consumption to about 1 - 2maH in idle. Thats like a 3-7 time decrease in comsumption. Its actually better to start an app when required and close it when it is'nt, anyway when you touch the touch screen consumption jumps to about 100mah, and opening of the app will not further load the CPU, although running it will.

Akshay

It probably consumes some power remaining idle in the background, but is it as much as constant opening and closing of apps? I doubt it

Like I said, touching the screen causes a greater power output than opening an app, say messaging via keypad, maybe you should stop touching the screen then to save battery? .
I have done extensive battery tests, with hard values, not just theory with a Windows based phone, i.e. HTC TyTn II. Apps are not recommended in the background, it takes up unecessary cpu power which is'nt in excess in todays phones, as CPU usage increases so does the battery usage, so if you've got your background apps consuming a steady 5-10% usage, an app requiring say 50% usage, would actually be causing 60% CPU usage, and this is an additional load on the battery and the phone, due to the increase in load, you get a bit of additional heat generated as well, which further reduces efficeny of the CPU.
Its a universal fact in the computer world that if an app is no longer required it needs t be closed and return resources. If a useless app hogs resources it will most definatley result in a crash of the system. Keeping an app in the RAM not only affects your battery life, but the overall processing ability of your system.

I thought the whole point of current UIQ3 device RAMs being upgraded to 128mb these days IS to enable multitaksing and more apps to remain in the background for faster access. What else would they be for then?

The RAM is upgraded so as to run larger programs, and more programs when required, not to open as many programs and to leave them there till the next restart.
Certain programs such as the dialer, messaging etc, are automatically loaded up into the RAM at boot for quick access. But say you're running GPS, you're not going to want it to drian your battery in like an hour running in the background, or a browser which again will eat into your battery. Also the first time you've loaded a program into the RAM and then closed it, the entire program is not removed from the RAM, but certain components that are frequently accessed remain in the RAM, let the developer decide which portion of the program resides in the RAM and which does'nt.
in UIQ phones there was a severe shortage of RAM, therfore the increase, when you constantly run an app, UIQ or SYmbian in its fir series 9 version was not returning the RAM ,i.e destroying its objects, while Nokia solve dhte issue to an extent SE provided more RAM so even if an app did'ntreturn the RAM there was sufficent RAM to prevent a crash.
I've got 4GB RAM on my comp, does'nt mean I'm going to open so many apps so that I'm left with none. For efficent working of s system there must be a lot of free RAM for the system to load up local variable, icons etc.. during its normal execution, RAM is not some sort of storage area for you to use as a temporary location for your programs.
Also Manfacturers add more RAM assuming that the end user of a smartphone has the basic common sense in realizing more open apps result in less battery life, till recent I was running PointUI in the background on my TYTn2 and this reduced my battery life from about 12 hrs to 8, this also depends on the optimization of the software forthe particula hardware. To go into details would be over kill for this post and its not related to the subject of this thread. But the bottom line is more open apps = less battery life, ask on any Computer based forum and thats the same answer you will recieve. Wheather you want to believe it or not is upto you, but I've conducted several tests, there are apps in WM which tell you battery consumption at that second as well as processor usage and temperature of the system.

GPS on the background??? Of course that's not the kind of app I'd leave in the background. Nevertheless, I will not elaborate my thoughts any further since unlike you, I have no facts to back them. Thanks for sharing yours. I'd like to leave this by saying more than 128mb is definitely welcome on WM and I'm guessing that the experts (HTC in particular) has started to think so too.

Its not just GPS, its any application.
If you've read any of my posts you'd know that I welcome the RAM, and I dont see how you associate more RAM with more battery backup though. I dont think I've mentioned anywhere that we require less RAM . And I think any expert on any thing related to computer systems could tell you that keeping things in the RAM is not good for overall performance of the system. I mean its common sense, extra load on CPU for no reason is not efficent from any aspect .

Is it only me or does HTC diamond and XPERIA X1 have almost the same spec.

Nearly the same processor, same type of gps, RDS radio, autofocus camera etc. Just some minor parts that differs, screen, QWERTY and their two own software's. |

I have to agree with AKSD, my WM runs out of battery quicker if I leave lot's of apps open.

Guess it depends on how you define almost.....
I think any devices in the same price range will be somewhat similar. What's your point? |

$949 sounds a lot better than $1799 but it's still off the chain! Almost a grand for a mobile?! I paid $1100 for a laptop!

Hi Rambo 47
But that is the price most top the range smart phones cost and they seem to be between £400-£600 depending on how soon after release they are. Both the TyTN2 and the E90 are currently around the £490 price point on Expansys and the HTC Touch Diamond is showing @£475.
Also making things smaller always seems incur further costs so i don't really see how you can compare a laptop to a smart phone look a how much more smaller and lighter less well specified Laptops are compared to the better specified bigger counterparts.
