View Full Version : battery life: Is it possible to switch Snapvue off / prevent it from starting up?

Hello,

Till you guys find a solution I am not using Snapvue at all, but the Shift very, very much.

My problem is that I load it 100%, shut Vista down..... and after 6 hours or so I lose 15% battery. Must be Snapvue....

I found a solution though:
1. Load 100%
2. Shut Vista down
3. Take out the battery and put it back. So no Snapvue startup.
4. After several hours still 100% battery.

Is there an easier way?


As I am flying a lot in the cattle class I need a small UMPC AND battery life.

Huib

P.s.

I am also in for some hints and tips which services I easily can switch off to keep performance up/battery low.

That doesn't sounds right to me.

I took my Shift off of the mains yesterday at around 4:30pm when I left work, and it's been sitting in my bag until I just read your post. Looking at it now, SnapVue has been running (with radio on) for approximately 28.5 hours and my battery is at 80%.

I actually thought I'd switched the radio off anyway, but it was still running and downloading emails all day.

Did you have the radio on for those 6 hours? If so, were you in an area where the signal strength wasn't good? I find my phones burn through batteries if they are continually hunting for a single or chopping and changing between 3G and 2G.

Winmo will run for 1-2 days checking emails without interaction.

If your signal was low and it was constantly hunting for signal then that would definitely drain more battery.

Well, Dave,

I did not have any SIM card in at all.
But I will give it a new try. Try to be more precise.
-I fully load it.
-Then shut down Vista.
-And I will calculate the percentage left after 8 hours. Maybe I have more time and check it after 16 hours too.

Anyway... taking the battery out-and-in solves it for me: stays on 100%

Ok, it was 15% in 8 hours in stead of 6 then. In that case it was right:
45% in a day and 90% in 2 days.

This heavily conflicts with Daves' 20% in 28.4 hours!

Since you don't have a SIM in the unit, have you switched the radio off?

and did he have the screen powered up? that is the single most factory to battery drain

Of course I did not have the screen powered up. That would take more than 15% in 8 hours.

Please.........

And I thought the phone is automatically off without SIM card.
My phone is in flight mode anyway, because I switched everything off.
But still, 15% in 8 hours is two days , so what's wrong with that?

So... once more. When I take out the battery and do NOT start Vista, the phone is not switched on, so power consumption is near to zero.



So: The only thing I am looking for is the software in Vista that triggers the Winmo to start. Because: Without Vista it never starts.

I doubt that there is "software" in Vista triggering WinMobile to start - as soon as you hit the power switch, both Vista and WinMobile boot up, but SnapVue is up long before the "PC" part of the Shift gets to boot Vista.

In that case it is over and out and I will do the battery removal trick.

Thanks anyway.

I am sure this is it:
After 5 hours I have 89% left with Vista swiched off.

So this means two days in total.
And no SIM inside, and in flight mode.

Dissapointing....

So I still I am waiting for the answer: How do I prevent winmo/Snapvue from starting at all.

I'm wondering if there's a problem with your Shift itself.

I had my on today to install Vista SP1 (which I promptly removed shortly thereafter!) and switched it off at around 4pm - just over 4 hours ago. It was on mains power whilst I was using it, and I switched off the radio on SnapVue after I shut Vista down.

Looking at my Shift now, my battery is at 98%. I won't be touching it again until sometime tomorrow (at least I'm not planning to) so I'll post further battery drainage details again tomorrow.

Dave

Hi foxmeister,
why did you remove SP1? I plan to install it as soon as I've got my Shift.
There isn't much commenting on SP1 installations. Can anyone comment?
I remember reading somewhere in this tread that others also removed it after installing.
Any differences between "original" English version and other countries' versions like in the Snapvue part.

Thanks!

Just logged into this forum now. It's just after 1pm here, so the last time I posted was a shade under 17 hours ago. Just checked my Shift, and the battery is at 95% now.

Working back to when it was last on charge, that's 5% in a little under 21 hours, with the radio and screen off.

Hi,

I uninstalled it because there were a few issues that I didn't have time to resolve. Specifically:

1. The HTC communications centre crashed a few times
2. Origami wouldn't always start - it would sit on its flash screen
3. Internet access via HSDPA didn't seem to work.

Rebooting a few times brought my comms centre and Origami back, so I'm sure I could get the internet access going again given time, but I go on vacation tomorrow and I needed to get everything important installed on the Shift before I leave. It therefore seemed prudent to just restore back to my pre-SP1 image.

I'll try again once I get back from vacation.

Dave

Mine, with flightmode on, drains like a watertap.

I will chek out why..
My tytnII stays on longer whennog using winmo.

exactly, this isn't a WM (=snapvue) issue, WM itself should be able to run for weeks in suspend

when you remove the battery, obviously you remove the cause of the problem too but that could be anything not just WM

mmh ... that's what happened on the video (the first video of the released version) .. it stayed about a minute on the flash screen and then he cuts the video .... not showing origami !

what do you think of origami 2.0 ? I'm following this project the closest I can from about 2 years and I'm really excited to buy the shift and try it !

To be honest, I don't like it. It's really slow with everything.
I even installed Winamp (full version).
Winamp is much faster and works perfect on the Shift.

But the Origami is really slow so that's why I don't use it :)

what about the battery drain .. who doesn't have it ?
how can it be possible to have a battery drain if Vista is completely off and that everything is turned off in WM (apart the OS itself)?

Thats is my question now already for some days. I do not even have a SIM card in.

I loose 15 % overnight with Vista off.

And I am still looking for an option to not have Snapvue startup at all.

Huib

P.s. when I remove battery and put it back of course there is nearly zero drain, because Mobile does not start at all.

well... I wish I had the shift.. because I'm sure I could help you .. grrr! have to wait 6 months :(.

I don't think that the WinMo is launched through Vista.. because it is two completely different CPU, OS, RAM, ROM,...

If there is an issue in WinMo, I don't think that you will be able to solve it soon ... we should find some ways to completely "block" WinMo.. but it will be hard.

I'm wondering if both OS are using the same battery .. you should try this test :

1°) load to 100%
2°) shutdown vista and keep the WinMo in the quitest mode ... and wait for 6 hours to see the result.
3°) load to 100%
4°) going to sleep mode (not hibernate) and wait for 6 hours... and look at the result
5°) compare the result..

15% in a night for a device that can stay for about 10 days.... it's a shame ! are you sure there are nothing on the shift (in WinMo part) that is working ? WIFI, BLUETOOTH, ... ? (even if wifi and bluetooth are for the vista side, i think that both comes from the WinMo part but used by Vista).

herpi
19-03-2008, 04:56 AM
OK, so...

1. I switched off WIFI first, when still n Vista.
2. I shut down Vista.
3. I did not do the battery trick.
3. I waited exactly 6 hours
4. .........Left 89%

No SIM card in, no Bluetooth, no WIFI of course

I will do the same test this night, but then in sleepmode Vista.
I am curious if it will be much much more drained.

Keep you informed.

it *can* be launched (reset etc) through vista, after all they are on the same motherboard, the two cpu's just have to have a way to talk. ;)

In that case the idea is to find what triggers it.
Lets be honest: No Vista startup: no Winmo.
Take out the battery, and put it back....no Winmo.
But when I come back from hibernated Vista: tralaaaa.. Winmo.

Could be that sliding switch though.

I am just an enduser, so maybe stupid question: Somewhere in the Bios?

mmh.. well... just try to look at the first boot if they passed the "bios" (boot loader for WinMo) at the same time.. or if the WinMo starts after the boot screen of vista (when you see the green screen).

vista is loading things only at this boot screen and after.. so if it boots before.. it's the bios or the button

I bet that there is a way to shut down WinMo (psShutXp -> 3rd party app) and let Vista started ... And then put vista in hibernation !


when you said "i remove the battery and put it back" .. you mean that you have 100% after hours... WITH the battery.. But just "not launching vista" after having removed and put back the battery ?

herpi

When I shut Vista down or hibernate it I still have Snapvue working.

Right! When I take out the battery and put it back, directly after that, I will not lose any power at all. Because Winmo is not started and, of course, neither is Vista.

So I keep 100% WITH the battery in it. And that can take for hours. I did not test it 24 hours. I may do this in the future. But I am quite sure there is no battery drain at all.

I did not fully test it, but also with an hibernated Vista and this battery out-and-in trick there is hardly any powerconsumption, lets say zero.

yeah but it's not really interesting removing the battery all the time ...
try the things I've said to see if there is something better to do...

try psShutXP .. and shut down WinMo with this application without shutting down Vista.

and try letting vista in sleep mode (and in hibernate mode) but without removing the battery. if no OS is started, there is no drain... we know it from what you said..

Yep, I tried the Vista Sleep mode. I went from 100% to 79% , but in 8 hours this time, so that should be about 84% in 6 hours. Not much difference with a shut down Vista I must say.

Installing software under Snapvue I don't know how that works, and, to be honest, is going far beyond my know how.

Huib

P.s.
I played VLC player in the airplane. Ok: I forgot to put the battery settings to "power saving" but still was dissappointed: After 1 hour and twenty minutes it was over. And I am sure I started at 100%.

I will check playing a movie in power saver mode and report about it.

So I did the same movieplaying, now with power saver mode on. After exactly one hour and thirtyfive minutes it starts beeping, and another seven minutes and gone...

And... last test, again in power saver mode, (which has no influence on the quality of playback) but now playing from SDHC card ( much less harddisk spin): after exactly the 1 hour 35 it rings the bell and is at 10 percent left. So another 7 minutes and over...

I could have spent my 1200 euro on so many other nice things....

thanks for the info ... so maybe the drain comes from vista that is in a state like sleeping ... or almost active (maybe for a hot start and not a cold start) .. i don't know !

2hours without doing anything and 1h30 while playing videos .. yeah it is... but you can extend battery life with "small" external batteries ! I know that it's not the nicest solution .. but it is simple and can extend for almost a day the battery life !

Just look at this thread :

If not.. you should watch this video (but be careful to be SURE there is a "/windows/startup" folder before... if not don't do anything (it will be safer) :

Yep. Here we go one more time:
1. I use Vista and, of course Snapvue.
2. I Hibernate or fully stop Vista. (Does not seem to be much difference.)
3. I Take out the battery and put it back in again. So now Winmo/Snapvue is not started at all.

With this there is nearly zero battery drain. Which proves that Snapvue is the consumer.

Dave says he has hardly any power consumption with Snapvue. So it is my problem only.

I am curious if other users can do the same trick.

Test if for 8 hours please, with Vista shut down and Snapvue normally switched on.

Sorry for the thread necromancy, but I've taken to putting my Shift to sleep rather than switching it off/hibernating, and I'm still seeing better results that you.

Specifically, I took my Shift off charge at around 7:30am this morning, which is some 7 hours ago. The device status was:


Vista - Sleeping
WM - running but screen off
Radio - on! (forgot to switch it off!)


As of right now, I've got 93% battery left which is only 1% an hour which is far, far better than what you are getting with Vista completely off, radio off, and WM on.

I would definitely be inclined to send your device back and ask for another.

Well, the difference is not big enough for me for sending it back.
When I have them all off, and after having removed the battery, the drain is nearly zero.
I can live with it. Better would be to find a way to close Winmo automatically instead of this battery trick.


I will see.

Thanx for the input
