Question is, is 128mb of RAM enough for a WM device? WM devices are known to be memory hungry. I was hoping SE would up their game and throw in 192-256mb RAM, something unheard of (like what HTC Diamond is now packing) to address to the WM situation or perhaps as an allowance for future killer apps that may require a tremendous amount of RAM. I wouldn't have a doubt if it were running on UIQ
I agree more than 128 would not be unwelcome, but I think it will run fine with 128. That's still a fair bit of memory, expecially if you store Apps on the mem card. Personally I actually don't find WM to be that much of a memory hog. Poorly written programs can pull the OS down, but if you have a good suite of apps that run well, then you can usualy have a fair bit happening before it starts to grind.
Using a third party task switcher that allows you to fully close apps when you close them also helps the mulit-task situation. Why have programs running that you aren't using?
Totally agreed. When WM Pro devices went from 64 to 128MB RAM they sang like a spring bird. HTC Diamond & TyTN II need the 256MB & 192MB respectively because of the Touch GUI overlea. Its VERY demanding and to be honest this is something Microsofts engineers/coders should've done from the get go.

The question is, why not? Constant closing of apps reduces battery life and being a work beast that it is, unnecessary power waste is the last thing it needs
You're wrong. Running applications consume more power than closing them. They use CPU and RAM in the background, how could they be battery friendly?

We'll theres no single app that can eat over 80MB of ram on the phon. Although with the larger screen size an app that ate about 1MB RAM on a QVGA screen should eat about 3-4MB on the VGA one. So putting in a bit more RAM would have been useful. But in "normal" daily usage it should be sufficent, unless like me you run pointUI, SPBMobile shell, GPS, CorePlayer and a host of other applications simultaneously, but if you did do that, battery life would be the least of your concern

AFAIK idle programs do not consume power, only when you're multitasking (eg listening to the mediaplayer while surfing the web) in which case all the apps are running at the same time. What I'm saying is some apps are convenient to be lying idle in the background while performing certain tasks with other apps. This saves time and power as compared to having to constantly open and close apps in the background. As we all know, P990 is useless in multitasking, apps have to be opened and closed all the time, that's why the battery drains much faster than P1 with the same battery.

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

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

6344 sek = 680€

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.
