Info on what happens when going into standby - Windows Mobile Development and Hacking General

It's been brought to my attention that applications keep running when the device is put into standby, while I always thought that the CPU would merely respond to interrupts which might then move it to a higher power state.
Try as I may, I can't find any definition of what is supposed to happen and if this behavior is consistent between the phone edition and the "normal" Windows Mobile or if it's even defined by each manufacturer. I've also surveyed the Power registry tree without finding anything that would tell me what happens to the CPU.
Any pointers to real information greatly appriciated.

as far as i know it's off and only the gsm part is running
and of cause the clock which is running in hardware much like a clock in a pc
of cause i could be wrong

well, no, I have clear indications that it is actually running. It responds to pings for one thing...

well maybe the gsm hardware can do that ?
normal programs are not running though like mediaplayers and programs you made yourself and .......

No, that can't be the whole truth. If it were, you wouldn't be able to stay signed in on messenger for instance.

I think it just stops most tasks (i.e. all non-system programs, some drivers as those of storage cards, etc.), while some others (notifications, keyboard driver, GSM tasks, ...) are still active. Additionally, the CPU is slowed down as much as possible.

I did some experiments today and here's what I found (on a particular device).
I ran a ping *from* the device to a laptop and sniffed the traffic with Ethereal . When I pressed the power button, what one would expect to happen happened: the pings stopped instantly. After a while I started a ping going in the other direction, i.e. *to* the device. Not only did this provoke a response, but the original pings from the device resumed, but the screen did not turn on. When I stopped pinging the device, the pings *from* the device stopped after a few seconds.
Clearly, the GSM processor is moving the PDA portion to a higher power state, at least briefely, in response to incoming traffic.

MDA Questions after a week of use...

Hello...
I recieved my MDA last saturday, and since then, have been trying to figure everything out. After multiple calls to tmobile, and even a trip back to the store, i'm still stuck with a few questions that i cannot seem to get answered.
1. The MDA came with the default Tmobile theme which works fine in portrait & in landscape, as well as the default blue Windows theme.
However, I have tried to install multiple themes(including some from microsoft themeselves) and i have one annoying error! Whenever I use an "installed" theme, the portrait screen looks fine, but when I open the keyboard...there are two large greyish/white gaps on the side of the theme.
Ex: I'm using a green theme. When in landscape mode, i have a single green square in the middle of the screen with a strip on either side(left or right)
2. My phone is HORRIBLY slow when and if ANYTHING 3rd party is installed. I've tried today plugins that control the memory usage(figured that would help)...however, it just slowed things done. My phone usually runs at about 14mb Free Program Memory, out of the total 44MB(This seems horrible...with just the default programs installed*for the most part* and maybe agile messenger running.). If i install a today plugin, or a game...this drops below 10mb. Therefore, phone usage can be very aggravating. I cannot think of any other way to increase this memory expect for ONE thing. Would it be possible to transfer ALL programs, applications, etc to the miniSD Card(i have 1gb now, with a 2gb in the mail). This way...i certaintly would not be topping out the usage of the card, and hopefully I can free up alot of space on the phone.
3. As we all know, the packaged IM programs are AWFULLY slow and inconsistent. After a bit of research and trials, I have settled on using Agile Messenger. I'm loving it...expect for a few things.
The MAJOR problem I have with it, is the pop up notification. Its annoying to be surfing the web or playing a game, just to have a pop up tell you that you have recieved a message, EVERY TIME you get a new message(which can amount to a great deal in a short time). I've looked all over for a setting, so unless I missed it, is there any way to shut this off?
A side issue with this program, and also the connectivity of the phone is...:
(even WITH the GPRS hack*always on*), I still lose connection(with 2-4 bars of signal) and therefore i get signed off of Agile, rather often. This isnt' such a problem with me, as seeing it takes a short time to log back in. However, when you look at the conversation from another person's point of view...all you see is
"Soandso" Logged off
"Soandso" logged on
etc
etc
(not sure if that last part was a question or a statement, but if theres an answer, i'd like to hear it!)
4.
My girlfriend has a sidekick, and I LOVE the feature of being able to set phone profiles for specific times of the day. Especially during school, it'll go silent, and the second we are out, its back on normal. I have downloaded PZP to try and fix this loss of luxury. However, I personally don't find the program to be very consistent. Sometimes, it seems as if say my "school" profile is fully functioning, while other times, it really doesnt. Call me crazy, but I have taken a shot in the dark and ventured to say that if one touches the volume button on the phone while the phone is on a specific profile...it will throw it out of its cycle. If anyone has some hints/comments/suggestions of their own on this program or other favorites...I would love to hear from you.
5. After I went about and downloaded the Eten dial pad skin, I noticed that all of my contacts were unable to receive contact photos. I quickly realized that any contact that was saved on my SIM card from my previous phone was stuck in this predictament. However, if i were to create a new contact account, it quickly allows me to customize them alot further. Therefore, i was curious if there was any way to transfer my contacts on my sim card>my phone in a fashion that the phone will accept them.
I'm sure i'll think of more questions(these are just the ones that I havent been able to answer after days of searching :-D)
Thank you so much in advance!!!!!!!!!!!!!!!!!!!
Hi,
the speed of the HTC Wizard is very slow. That was my problem too.
for question no. 2:
Moving the apps to the card will result in more free space on the phone, OK, but running the apps from the card will also result in low speed, because the card is slower than the main memory. So I think you won't get more speed by this.
Try to overclock the device with OmapClock. My device works like a charm with 264 MHz (original was 180 MHz).
Use a tool like FreeUp RAM, which is part of the SK-Tools-package.
Running OmapClock and freeing up the RAM from time to time brings significantly much more speed. There is almost no waiting time if you click on an icon. You can even run Skype with OmapClock (many other users do so).
HTH
I have seen tidbits about overclocking through my endless searches the last few days. I've always heard that you have to be careful if you overclock a device, such as a phone. Has anyone had any known issues with the overclocking? Are there risks in having the phone run at that speed all the time?
The Wizard isn't slow. Install a Qtek rom without branding, and it will be much faster.
even the sales associate at tmobile seemed to think it was slow. Upgrading to a different ROM sounds ok, but i'm trying to keep everything via tmobile. thaks for the tip though.
Hi,
Im looking to get the Tmobile USA MDA, but after reading posts like this Im alittle afraid.
I need to run TOMTOM on this device and thinking that this might bring the device to a halt. Now Im starting to think that maybe I should get the 6700. Please let me know what you found out about making MDA faster. Thank you.

There have been long discussion about what is safe with the Wizard on this forum.

There is a known problem with backlighting. See http://zendrui.free.fr/PZPForum/viewtopic.php?t=197
Also, check to see what events PZP is handling for profile-switching. For example, if you have calendar-based or time-based rules, they may switch your profile without you doing anything. Go to Settings, Control to see what you Switches you allow. Or check Time and Calendar for your profiles under the Configuration option.
As much as i'm sure overclocking the device may help, especially in my case. I'm just not sure if its worth the risk. Kind of hard to explain to Tmobile why the phone decided to overheat. Seems overly risky to make such an expensive device, run at higher speeds than its DESIGNED to do. But i'm still not sure, it almost DOES seem worth it...decisions, decisions...
Yes, Thank you for clarifying that...I mostly meant, the inconsistency of PZP with the timing of profiles. It seems as if the program will "switch" to the correct profile, but i don't always see a change in the operation of the device itself. Ex: I have it set to go to school mode at 7:30am, this past week(since its spring break, i've noticed that my incoming calls all had the normal ring volume, as well as system tones, etc...
Although it "says" ""School"" i don't really know if its truely in that mode?!
On this note, i have a question about setting the times(which is what i really want to accomplish). My phone goes to LOUD around 5:30am, School at 7:30 am, Normal at 1:55pm, and Quiet at 4pm.
Nooow, do i have to put two times in the school profile such as 7:30 am-1:54(5)???? so that it has an entire time interval...or can i just tell it when to start, and the next profile will automatically kick in and stop the previous.
Also, does putting the phone in standby or shutting it down have any effect on the profile??
I'm sorry in advance if i'm asking very basic questions, i've just been searching for a long period of time, and i usually can't find a specific answer to my question. So I decided I would spend the time to actually discuss MY problem, with hope someone can help. Again, sorry for any inconvienence or redudant questions.

I have a german T-Mobile MDA Vario (= HTC Wizard) and I'm overclocking it permanently with OmapClock and SmartSKey. There is no overheating as far as I can say/feel. I can speed up to 264 MHz (original = 180 MHz). If I try more, the device softresets itself without any damage or loss of data. It's a kind of security mechanism. Of course, battery life is a little bit shorter when overclocking it. But I'm sure, slightly overclocking doesn't damage the device! Maybe the lifetime of the device will be a bit shorter, lets say 6 months in 5 years, but you won't realize that, because you won't be using your device in 5 years. You will sure own some other phone when the CPU dies. Together with the tool "FreeUp RAM" (comes with SKTools), I can reach a comfortable speed for everyday use. But never forget: The Wizard IS quite slow, compared with other devices. You can find smart workarounds for that, but don't close your eyes on that fact.
For running any GPS navigation tools I would consider buying not a Wizard, but a much faster device, if you would ask me. I'm using my Wizard only for addresses (~ 700 items), calendar (~ 1200 items) etc., and without overclocking and using a program like Pocket Informant 2005, that would be an annoying, maybe impossible thing. At the beginning, I had to wait almost 10-15 seconds until e.g. the month overview was created. Switch to the following month - wait again. Choose a specific day - wait again. Oh my god! That needed more patience than I had.
Are you running a basic install without all the phone networks customisation bloat?
you can do this by hard resetting (you will loose data doing this) and then doing a softreset when the customisation dialogue pops up after setting time zone etc.
this will speed things up over an install with tmobiles bloatware. I run tomtom and my device is in general as reponsive as the magician it replaces.
good luck with your phone

So guys based on your opinions and experience is it worth for me to get the MDA or should I go with a different carrier and a XV/PPC-6700 ?
Hi yozh,
I don't know the 6700-device at all. Maybe we don't have it here in good old Germany, or maybe under a differnt name. Does it have a bigger display (better for navigation)? Does it have a faster CPU? Then take that one! In my eyes I would never like to use the Wizard for navigation. It's only a better phone, not more, not less. For all other purposes I would buy a bigger machine. I do not want to talk bad about my own device, I have bought it and I use it and it's OK for the everyday things I do with it. It has nothing to do with "I'm proud of my device", like some people seem to be here. It's a phone, man, not a Ferrari or a Rolex. You would tell yourself lies, if you would call the Wizard a powerful device. I had a Palm Tungsten T5 before, and THIS is a powerful device. 2600 items in the calendar (true!), and the reaction time was half a second if you tap on the screen! You can go and have a coffee if you do that on a Wizard.
Just think about it. If you buy a Wizard, try it for a day and then write to me what you think about that phone.
Mh. My english should be better, I know.
Just my 2 Cents!
Hi well the 6700 is the apache I belive and the CPU is 416mhz but its not a "dual core" everything else screen adn such is pretty much the same. Thanks for the reply
SO any one on this forums can recoment apache over MDA ?

See my posts on http://forum.xda-developers.com/viewtopic.php?t=48448 regarding processor speeds and TomTom.
Wow really TOMTOM runs better on the MDA then on a 400mhz DELL ? Then Im set defenatly getting the MDA, I like GSM network provide3rs better anyway and plus there are so much choices with the phones. I wish I was able to aford the JASJAS that looks really good.
Also don't forget that when you 'close' an appliation it does not really close, it just goes in to background, thus slowing the system down.
Check out your running processes and close all the ones that are not needed or load an app that really closed things.

Themes built for portrait screens look wrong in landscape view. Easy solution: build a theme that works in landscape view. The Guava Bubbles theme works fine in both because the background image is larger than portrait size.

I use PPC-Profiles-Pro, but you can't slave this to a time. Besides, I'd rather just put it on Silent mode by holding the connection manager button for three seconds (top left side button). Otherwise I use PPC Profiles to switch from Work (BT) to Home (Wifi, no BT) to Sleep (No Wifi, no BT, no email alerts or reminders, just ringer). Walking into a theater, I just go to silent mode.

GPS Today

GPS Today
I am very impressed with this program so far. Found it at
http://www.freewareppc.com/download/travel/gpstoday.shtml
Like Google Maps but with a Today Plugin.
Works easy and fast!!
Try it!
Mobo
Sounds cool, I'm trying it now. Here's a link to the full page with the description: http://classic.pocketgear.com/software_detail.asp?id=26396
Application Description
GeoTerrestrial GPSToday is a lightweight today screen plugin that will allow you to utilize the full capabilities of your device.
* It utilizes intelligent algorithms to always maintain and display a fix on your position right on your today screen, without draining the battery.
* Always see your full street address, not just geo-coordinates.
* Currently WORKS in the US only!
* Slide the red icon over to the right to start the GPS in continuous mode, or single-tap the red icon to start the GPS in quick-fix mode.
* GPSToday always shows the distance to the nearest contact from your device's address book.
* Single tap to create a new contact with your current location as the address, or save the current location as an existing contact's address. Imagine not having to type the full street address on the PPC keyboard!
* You will never need the stylus to use GPSToday!
* Speed, heading and satellite data is shown clearly on the today screen whenever the GPS is running.
* In-pocket tap protection. A single tap on the today screen only operates the GPS in quick fix mode. To fully start the GPS in continuous mode requires an iphone like sliding motion, guaranteeing no pocket accidents.
* Single tap from the today screen to access fully draggable online maps!<

* Single tap from today screen to quickly do a yahoo local search around your current position and see the results on a live map. Just tap a result to call or open the website.
* High quality Yelp Reviews for local search results!
* Fetch the full street address for any point on the map.
* GPSToday automatically disables data access when your device goes into roaming mode.
* And many more features.
* Best of all, its free!
Update Description
Added Note: Currently Works in the US only!
i'm trying t too
I'm really curious how can it be "without draining the battery" when internet is active and gps is active. If those two features are active then battery must be drain more than normal usage. Hopefully, someone can measure it. If it is true, we can have GPS open all day long without worry about battery drain and in the same time no need to wait for "cold" boot and have instant gps when open tomtom or other gps application.
I had it on my device for the last few days and while it does offer direction, speed, etc it does consume battery life. It stays active and when it hits open sky, begins the search. Several trips home from work monitoring my speed yielded a very warm battery...

There should be no extra Battery drain with GPS on because GPS doesn't require the transmitter to be turned on like the internet access does.
The receiver in the unit always stays on (so you can get calls) so receiving satellite data doesn't require any more power than normal.
The internet connection DOES drain the battery though as it needs to turn on the transmitter each time it sends data.
i used it this morning and last night.
first off, it leaves the data connection active while it updates your location/address so yeah, it drains the battery. i lost 10% or so in about an hour of constant use. but keep in mind that also had the screen on while i was watching it. next, its a little buggy because, for me, it would stop GPS'ing when the screen shut off and once the screen came back on, it would get the sats for about 20 seconds then stop. i have to go into the map, choose MORE, and chose run GPS to make it stay on. all in all, its a really neat app, i love the speed part.
I just found this the other day and tested it. One problem I had was I had to go to the map to keep my connection open. It kept turning on and off until I clicked on the map and it didn't turn off afterwards. I didn't have to keep it open. I just opened and closed it. It seems to get a pretty quick connection when outside. It seems to be a memory hog I think for what it does. I start at 11 mb with just this on the Today screen using NexVision rom, which I usually started at 15. I like the plugin. I wish it didn't use at much ram as it does.
OK.. I might just be lame but I ran the cab on this.. Did the soft reset and there is nothing installed for it.. In my programs there is no listing for it and on my storage card (where I installed it) there is only a listing for a help file that does not open...
Any ideas??

If you delve a little bit deeper into how GPS receivers work, you'd understand that it actually does draw quite a bit of power. Also, the mogul does not use aGPS, which uses the cellular tower information to help get a faster fix without as much effort on the part of the GPS chip. Your explanation of "The receiver in the unit always stays on (so you can get calls)" doesn't make any sense in this case since the technologies do not rely on each other.
To prove my point:
Turn off the cellular radio on your phone in the comm manager. Turn on Bluetooth. They both use a receiver, however bluetooth uses far less power than the cellular radio. Your battery will last longer. The GPS radio also uses power, perhaps less than cellular, but more than not using it at all.
BOTTOM LINE: Leaving GPS on will eat your battery. Period.
it's a today plug in. if it doesnt show up, reinstall it to your device
This program makes my mogul really slooooooooooow...
hmmm, I was really trying to prevent downloading on device but i'll do it and hope all works.
Update. I now see the gps but my phone is slow as dirt. Cant even click on Start or anything....whenever I receive a new message I get same issue...bout to soft reset again to see if it works a little better....
seems to be running better just needed time to boot up I guess....should we be changing anything on GPS settings? I feel like I just got a new toy man...
Seems like a cool new toy.. I cannot wait to get outta the cave I am working in right now and see how well it really works with a sat signal...

and besides that, even if the gps doesnt need extra power to recieve GPS data it still has to do something with the data, that means the processor is running, stuff is being written to and from RAM, then displayed on the today screen, all this takes more power that doing nothing
anyway, i ended up having to prime the GPS with google maps to get this thing going, and the today plugin flickers rather annoyingly (and its definately eating the battery, i got it charging now but its charging up a lot slower than usual)
hmm, i have google maps on my laptop for mobile. I will attempt to install later. as far as the gps working, I was driving to work and it showed me how fast I was going and how far i was from work. I didnt even put it to search for work but it must have found the address somehow in my phonebook?
I'm lookin at the program and its linking to an Autozone that is 5,397.7 miles away from me. I know which one they are referring to since i saved that name and number but i'm pretty sure its closer than 5 thousand miles from me...WTF
i'm still trying to learn how to use this...
program seemed REALLY cool.. but while it was installed and looking for a signal it seemed to REALLY lock up my phone... I could not do anything on it for a couple mins. I will keep an eye out for a newer version when it comes out since I did really like the concept of this program...
Thank you
Hi all,
First, its wonderful to see so many positive comments about the software just days after its first release. Now we know we are on the right track!
Secondly guys, apologies for the bugs/issues you faced, or are still facing. This is still version 0.9, so its actually a beta release (not that that's an excuse!). Also please excuse us for the lack of documentation.
About the "without draining the battery" part, I agree the language is somewhat confusing. It was meant to compare with the consumption that would occur if the GPS were actually running all the time. You'll agree that if you start up the GPS at 8:00 in the morning on a typical Phone-PDA and leave it running non-stop along with an active internet connection, it will not last until noon. With GPSToday one can get the same benefit throughout the entire day. There have been some inconsistencies though, with some users reporting almost no perceptible change in battery life, and some being seriously affected.
Please note that tapping the red icon on the today screen is intentionally meant to temporarily start the gps, obtain a fix if available, and then stop. To start the GPS in continuous mode from the today screen itself, drag the red icon over and drop it onto either of the two icons on the right. Once you are done, you must remember to stop it by repeating the same gesture. Also, try this once if the automatic mode is not able to get a fix the first time you go outdoors.
Memory: our tests indicate significantly less than 1MB consumption when the map window is closed, and about 1.5 Mb overall when the map window is being actively used. We agree this is a bit high (but nowhere close to the 4mb one of you is reporting). Some of this is also an offshoot of the fact that it uses up only a tiny amount of storage memory, < 200kB. Nevertheless, expect to see ram usage being reduced significantly in later versions.
Lastly, please fetch the latest version 0.9.1 which fixes some battery life issues and other minor fixes, from Pocketgear at http://classic.pocketgear.com/software_detail.asp?id=26396. Make sure the download filename is GPSToday091.CAB. We recommend a soft reset immediately after installtion. We also promise that from v 1.0 onward soft resets will not be required!.
Thanks!

The Sprint HTC Mogul... just sad :(

I just ventured into the PDA world with a Sprint Mogul and it's been nothing but disappointing so far. I have been on the phone with Sprint and HTC practically everyday. Can anyone shed any light on these issues??
- Memory, says roughly 49 MB of which over half is taken when no apps are opened.
- Tremendous problems accessing mobile websites, such as my bank, which has a mobile site (I can see it, just can't get into it... well twice I did, then error messages).
- The phone seems to drop my e-mail services for no apparent reason... e-mail works, then all the sudden, asks for my user names and passwords, which when I enter, says it's wrong. Reboot the phone, and back in business.
- It will not download and use many of the sites/programs made for mobile (gmail, AOL instant messaging, youtube - gotta do something sitting in airports).
- Screen useless in sunlight.
- Locks up constantly. If you are performing a function, and something else kicks in (text message, e-mail, phone call, etc) everything locks up, and you have to reboot.
- Locks up constantly. (see above)
- Locks up constantly. (you get the point)
- I have to reboot roughly 6-7 times per day.
- If performing a function, and something else kicks in (phone call, message, etc.)--and it does not lock up completely--the current function is blown out and you have to start over.
- If using Sprint Navigation, basically everything else is is unusable.

sorry
I'm in no way a power user, i just like to **** around with my phone. However i don't experience most of your problems, however i will address some of the issue you presented us with
First of i would suggest running a cooked rom (http://forum.xda-developers.com/showthread.php?t=385336 this is for dcd 3.0.4 its what i run), however if you don't want to for what ever reason then:
as for your first point (and last point) of memory we all know that it blows on the mogul and the tilt is a newer phone that is why i think that the tilt has more memory
The internet, i personally use pie normally, and i have been able to do banking and such with pie. however pie plus, opera and whenever skyfire comes out (demo video here http://www.skyfire.com/product/index/demo08) are some good alternatives
The email issue i don't know what to tell you, i have two gmail accounts set up on my phone, and one for my school email phone and they always work for me. There is a setting to have your phone remember your password, so maybe that will help
As for things to do in an airport, it is possible to watch youtube vids (http://forum.xda-developers.com/showthread.php?t=343397), gmail i already talked about, and if you know the right .coms you will find aim (i use it all the time)
The screen is kinda bad, however with the brightness setting on one of the higher settings i can you my mogul in direct sunlight (true it's kind of a pain but doable)
Your lock up issue, i don't know what to tell you. Mine never locks up. I have my mogul on pretty much twenty for seven and like once or twice a week i reboot, but i don't have a lock up problem.
i found a program that will back up your contacts and such, i haven't used it and can't find the thread about it, but it was on this forum and people really seemed to like it.
sorry that you are having problems with your mogul, i think the mogul is a very good phone and i really like mine. Any issues that you have with your phone is already solved somewhere in this forum (thats how it was for me)

The moguls only has 64MB of RAM, of which some is required for the OS and various other functions. 24MB free is at bootup is a pretty good number for this phone -- and achievable.
Mobile websites don't seem to be a problem for me, maybe it is the version of PIE that you're running, are you using the stock ROM?
E-mail... never had that problem, maybe something is going wrong with your actual servers?
Turn the brightness completely to maximum in sunlight and it will be usable, just not perfect. You need something like SPB Mobile Shell to be able to access the backlight brightness quickly.
Install dcd's 3.0.4 to address the lockup issues.
Use TomTom, iGuidance, Google Maps, or some other navigation. You have to pay for Sprint Navigator monthly anyway.
Get mail2web free pushmail and sync to their online exchange. It's much more convenient that way anyway.
The Mogul is a generation 3 device while the Tilt is a generation 4 device. The comparison is like trying to put the 1993 BMW M3 against the 2008 Mercedes Benz S-Class four door saloon. There is no comparison! You'll have to wait until CDMA carriers have generation 4 or 5 devices and by then GSM providers will probably have generation 5 or 6 devices. Vicious cycle...
Goodluck!
best thing you can do is just sit at your pc and read read read, and when your done read some more.
the people in here are truly good people and will help you with your questions and youll get it goin just how you want it. just takes alot of hard work to even half way figure this thing out. to me the mogul is the best phone out there and this site is the best one out there as well.

WELCOME TO THE WORLD OF WINDOWS MOBILE!
First things first. Read the upgrade forum for instructions on how to ditch the BS ROM that Sprint ships with your phone. Get on DCD's rom. Its screaming fast and doesnt lock up.
As far as your problems accessing websites and downloading things, 99% of your problems can probably be attributed to internet explorer mobile. Ditch that piece of crap. Get opera. Its worth the money or try to find some place to download the new opera 9.5 beta. There should be some cabs somewhere around here...
As far as your navigation slowing down your phone, again its attributed to Sprints crapware ROM that slows down your phone. Get on DCD's.
Make sure your screen brightness is turned all the way up. It could help you see. WinMo auto adjusts this setting sometimes depending on certain conditions. Always check first.
And as far as syncing? Are you just talking about your contacts? ActiveSync (on XP) and Mobile Device Center (Vista) will sync pics and vids and everything without Outlook installed. Or do what I do and get Outlook and just use it for your contacts. you dont have to use it for email.

Yes! I think this sums it up.

opera has two flavors for windows mobile, opera mobile which is at 9.whatever, and opera mini, which is at 4.1 beta.
opera mini is the best browser ive used so far on the mogul. i am a beta tester for skyfire, and while the video,java,flash, and sound support is pretty sweet, it doesnt feel refined for a mobile device like opera mini does. i like putting my web pages in mobile mode and scrolling a page at a time by using the directional pad. if skyfire could do this, then it would be my fulltime browser. until then, ill only use it when i want to see flash,java,video,etc...forgot to mention skyfire eats RAM like a slot machine eats my hard earned wages
YMMV though
kmart is right, two different versions. opera mobile is a software that you have to pay for as opposed to opera mini. opera mini is mostly designed to work on java based handheld phones (like razrs) but it works well on ours. The current version of opera that you download off of their site for windows mobile is 8.65, and its good but its a big piece of software and sometimes can eat a lot of ram for our tiny titans. check out this link, i uploaded a mirror on my site of the beta for you.
@kmart, i just got my skyfire invite two days ago. its definitely cool, but still needs some work. I love how fast it is but to be completely honest, i had no idea before i downloaded it that it used server side rendering. It loads everything i ask it to pretty perfect. I am happy with that for sure.
found one thing skyfire wont load though. speedtest sites. No matter which one, or if i have searched for it or typed it manually, it refuses to load a speedtest site. strange, huh?

agreed, the one thing worse than a stock winmo rom from a carrier is the stock windows operating system on your computer. effing norton....
Also, while MS does push outlook (and this is the first Windows Mobile/Pocket PC I've ever seen that doesn't come with a full version of Outlook on the disc... What's up with that?!), its not the ONLY way to sync.
You could get a free exchange server with mail2web which would sync all your stuff over the air to their server in real-time. It may use data (I'm assuming you have unlimited data) and add a little drain to your battery, but you never have to back anything up manually (constantly in sync) and you can access your information by going to live.mail2web.com from any PC browser, and anything you enter will be pushed immediately to your phone.
Problem with this method is that its web-based, so its not was smooth to use and enter info as a localized application (plus you're relying on having a net connection).
There are some open source and free outlook alternatives, such as EMClient ( http://www.emclient.com/screenshots/ ) which claims it will support direct sync with activsync like outlook does in the new version due out soon.
There's also funambol, which like exchange above, uses over the air sync routines so you don't need wires or even be near your PC. Advantage to this is that its fully customizable and can be synced with almost any desktop client since it uses an open source platform and based on the standard SyncML (from linux) protocols.
They have a free server at my.funambol.com you can use, or you can host your own to do some fancy configuring.
As far as locking up... Look, this is a powerful OS, and I've seen far too many people get into it without knowing what they're doing, and be instantly turned away (later going with something simpler and more spoon-fed, like palm or the iPhone). If you don't want to take the time to learn how to use it to its potential, this device is not for you.
If you do have the patience, you'll wonder why you ever considered anything else. Just for reference: I go for weeks without a reboot required, and my battery can last almost 2 full days of moderate use, using a live over-the-air sync (currently on funambol).
I have to second the notion of those that say to upgrade to DCD's 3.04
Been running that for a week now and it really is much more stable than even the stock roms!
As for the memory issues people need to remember that the memory use is dependent on what the device is doing...
You could have very few apps running in the background yet still wind up with very little memory if you have a lot of graphically intensive programs running. Hell you will eat up as much ram running a small launcher with 10 icons as you will by running any full program!
Every thing you see displayed on your screen eats up program memory.
Every today plug you run does too...
Background services like the GPS chip will eat up ram as well even if you have it shut off!
So you really have to be thrifty with what you have run by default and load things as you need them instead.
I also find it useful to reset the phone once in the morning to start off fresh each day.

Amen to that. Amen.
can't stress enough how much better your winmo experience will be if you shut it down once in a while. And check your task manager too. you might be running a lot more apps than you are expecting.
Eh, that shouldn't be required.
Unfortunately, Windows Mobile cache files don't always let go of the memory when u need it most, and this effect varies from rom to rom.
DCD and no2chem's are both better at this than the stock rom.
But either way, if you run a tight ship, properly closing apps and running a strategically placed hibernate command every now and then, you should be able to go for weeks without needing a reboot.
Personally, I end up rebooting a couple of times a week, but not on purpose.
Usually because I actually have to turn the phone for a moment to either save battery or going someplace they don't allow phones. I rarely reboot "just because" anymore.
im running quite a bit of software full time on my titan and sometimes that software crashed (read: wisbar and wisbar desktop). this forces me to restart. but you are right, on my base config (running a custom compiled version of DCD's 3.0.4 currently) i never have to really restart. Windows mobile is great, if you just give it some RAM breathing room and dont turn the processor into a puddle of mush inside your phone trying to play crysis... it just doesnt work well...
IF the unit had the 128 ram the unit would avoid most of the problems people have with it...
WM has always been a system that you had to stay on top of the Ram. But that has always been because Ram was so limited...
Using HTC X Button set to close apps on X Press greatly decreases the problem of running low on memory.
Using the DCD ROM and the PPCG Kitchen, I was able to find a setup thats leaves plenty of RAM available.
The key was not to install too many Apps that need to run in the background on boot.
SPB Phone suite took the place of about 4 or 5 different apps so I could leave them out of the ROM.
I have found however that some graphic and data intensive apps work better if you do a reset first...GarminXT comes to mind.
If the unit had 128 Megs of Ram it wouldn't be an issue...
I also save a lot of problems by having an 8Gb SDHD card to install all the apps that don't require installation on the device...
my phone pissess me off from time to time but I am a power user. I use my phone for navigation, mp3, watching tv (slingbox, not that bootleg sprint tv), and your standard features. Everything is installed on my 8 gb memory card to avoid any weakness in memory, yet my phone freezes from time to time, screen doesnt work (rarely) and i get memory low messages when attempting to do certain things. Its the only phone that really fits my needs and i'm kind of overloading it with applications but as a power user, these are the issues I face. Some of your issues...seems like phone may not be setup properly? I would take it to a sprint store, let them look at it. Much easier to deal with someone face to face rather than over the phone.
That was a helluva 1st post. Welcome to the board.
Like others have said, use a custom rom; it's much cleaner. The stock rom out of box probably needs a few things added to make it stable. I've used the stock rom just fine (don't prefer to, but it works).
Sounds to me like a you may be doing a poor job managing your program memory. Simple things like the X-Button, help a lot.

Androids energy efficiency?

Uhh, I cannot post this in development as I am still a newby :-(
However:
Hello,
I came from Symbian (Nokia C7-00) and liked the phone very much. Everything worked the way it should. (I was especially interested in office functionality.)
Now I bought a Galaxy Note and I really love the hardware.
But I discovered that it uses much energy and it doesn't like to sleep as often as it could. (I already returned to Android GB, which gives a better experience, but there still is room for improvement.)
1. Sometimes even though the phone simply lies around and does nothing, the last app that I forgot to close is hindering the CPU from sleeping. Why? The is no need.
2. At night I am used to turn the phone into flight mode. However I found out that this isn't the best thing for Android. In the morning, when the email app goes to push phase, the phone leaves sleep mode and seems to excitedly wait for the flight mode to get switched off. This uses *quite* a bit of battery!
These things seem strange to me. My impression is that Android is not really optimised for cell phones. If the screen is off, there is no need for CPU time, doesn't it? There is nothing urgent to do; everything could be done slowly; no hurry.
I guess the battery could last *much* longer if this would be improved.
Greetings,
corcov

Doesn't matter.
Development, if you did not create IT, then it does not belong in development. Remember that. Otherwise you will get flamed.
Android is a mobile OS, so of course it is optimised for smart phones - not ordinary cell phones. Android acts like a computer and, if you keep a computer running Crysis 2 for example, it would burn more power than a computer just playing some music off of iTunes.
In terms of improving your battery, check your brightness. You can download widgets to adjust the brightness right from the home screens. I use these to set my brightness to its lowest whilst at home (perfectly adequate for night and indoor use away from sunlight) and turn it onto automatic when I go outside. This has saved my a bunch of battery.
If you are running a stock Samsung ROM, turn on power saving mode. I always leave it on and, frankly, I have no idea as to what it actually does. I haven't noticed a performance drop in the slightest, but if it saves a bit of battery it is worth it. Also, you could try Juice Defender or some other battery saving apps which work for some people - others not.
Finally, ensure you haven't left GPS, Bluetooth or WiFi on when not needed. Try downloading CPU Spy to check your phone deep sleeps, yet mine even without it ever deep sleeping gets around 16 hours of battery life which is still the best I have ever gotten on a smart phone. Bettery Battery Stats can show you wake-locks (apps that are keeping your phone active) also.

I see. Well it might be a nice feature if one could add an "now be a cell phone"-option for energy enhancement, which means: if screen if off, sleep.

There are some legitimate needs for keeping the CPU from sleeping for a short period of time - such as finishing a sync operation (otherwise, the radio power spent beginning the sync is wasted). Unfortunately, some poorly written applications (Facebook for example) abuse the wakelock mechanisms and hold wakelocks when it is not justified.
2. At night I am used to turn the phone into flight mode. However I found out that this isn't the best thing for Android.

This is not something I have ever encountered myself. "push" relies on the server to trigger something - in airplane mode, this trigger can't happen.

Android is well optimized for cell phones - However, it assumes that third-party applications follow Google's recommendations for power management. Unfortunately, many of them do not. The number of IM applications which choose to use their own proprietary and poorly optimized network protocols (such as Skype, it's atrocious) as opposed to Google C2DM (optimized and efficient) is astonishing.
An interesting note was that I believe much of the focus at Google I/O was on reminding app developers that they need to play nice with the system and other apps.
There are some cases where there are device-specific nonoptimalities. Compared to most Nexus devices, Exynos devices have an absurdly long time to resume from wake (1000 milliseconds), and during that resume cycle CPU frequency is locked to 800 MHz and cpuidle is disabled. This is one of the #1 causes of power drain on our device. This is also exclusively a Samsung kernel/hardware architecture problem that does not affect the Nexus S (similar CPU, but completely different modem interface) or the Galaxy Nexus (different CPU/modem interface).
In the case of our device, the modem is hung off of the CPU on a USB bus - this makes for very long resume times.
Here are obvious reasons the CPU should occasionally turn on when the screen is off:
1) MP3 playback in the background
2) Handling of background syncs - e.g. when an email or Google Talk IM comes in, wake the CPU, handle it, and pop a notification sound, then go back to sleep. Normally, this means the CPU sleeps while waiting for an interrupt from the WLAN chipset or the cellular radio. Unfortunately, some apps drive incoming data to the device far too frequently. (See my above rant about Skype's network protocols being crap compared to Google's C2DM protocol.)
3) Handling of scheduled wakeups (alarms, calendar events, etc) - these are rare and almost never consume power
Most power drain is from item 2, with third-party apps frequently behaving extremely poorly compared to Google's own application suite and sync protocols.
Now this an extensive answer which is very informative and helpful for me since insights are always soothing. Love it. Thanks!
not much to add after Entropy, but if you feel the need to get some control over battery usage you could try betterbatterystats app (and the thread) to identify battery eaters, besides that, there are few apps to check what is going on with your system when it sleeps:
- CPU Spy to show cpu states time
- Autorun Manager or Autostarts to disable triggers causing apps like FB to run without reason (those which you will find with betterbatterystats)
- Battery Monitor Widget, to check battery current consumption (mA) - this app is generally not recommended, because Note's hardware does not report the actual current, so the readings are highly estimated and because when poorly configured it can drain your battery faster, BUT otoh with refresh rate set at 5 minutes or more, it can give you some approximate orientation on how much battery you lose (better than counting %/hour by yourself) at negligible battery usage
- also, if you feel the need to disable net and sync during night, you could automate it using "lama", which is free, and in my experience does not eat much battery by itself
- and last but not least, avoid taskillers, those apps may have adverse effect, i.e. self restarting apps (by the triggers mentioned above), will get killed then restarted and so on and so on, leading to much higher battery drain

How does the NST know what time it is?

This is not an earth-shattering question or one likely to lead to some nifty application, but I got to wondering about this the other day and realized that I had no idea how it happens.
Scenario: someone purchases a Nook fresh from the factory and decides to skip OOBE. Will the device know the correct time? If not, is the only way to set the time via ADB?
Scenario: someone leaves a Nook in the bottom of a drawer and "discovers" it three years later. After charging, the Nook comes on...but how does it know the time?
My knowledge of time-keeping goes back to the old days when PCs had little batteries for this sort of thing. In my day I actually had to replace a few of these on aging machines. I don't even know if this is still the way things work. All devices seem to have internet connectivity and can obtain the time that way. For example, I have a SIM-less little smart phone I use as an mp3/audiobook player. It has been gutted of all the 3G stuff and other phone miscellany and consequently when I turn it on, it does not know what time it is unless I turn on WiFi for something. Then it will lose that time setting when I turn it off. Not a big deal for how I use it.
So...how does the Nook tell and retain the time?

It probably hits up an NTP server if you have the WiFi on.
Of course I never turn on the WiFi.
I use my adbtime.exe (I don't think that I posted that utility) so that when I sync I set the time.
In between it keeps up (even when sleeping).

And if it has been sitting at the bottom of a drawer in the "off state" for a few years, and you turn it on...but don't connect to WiFi?
I guess where I am going with this is whether there is a little man (or woman) in the machine who sits there and surreptitiously uses battery power--even when the device is off--to run the clock. Until there is no more energy available. This description--if a bit fanciful--seems likely. Even my tablet remembers the correct time without connecting to WiFi and I shut it off every night. My little once-a-smartphone, I understand, because it was designed to get time from the cell radio and therefore had no need for other ways to keep time. Therefore with the cell stuff trashed it cannot keep time once turned off.
So unless there is a special hidden battery (like on the old PCs) for this purpose, the energy for timekeeping must come from the (only) battery, even if the device is off.
No hidden battery.
Apparently you didn't read page 2611 of the i.MX 6SoloLite Applications Processor Reference Manual closely enough.
Didn't you read any part of Chapter 42?
(It details the Secure Non-Volatile Storage Real-Time Clock.)
