Want to double your e200 battery life for free?

Now, at first i thought i was going crazy so i called in Pagemakers with his two e200's to test this.

Basically, as far as we can tell, running your e200 with a SD card in slams the battery life. I get 3 days standby non stop without my SD card in (and a lot more free system memory showing in taskmanager) but if i use my SD card i'll be lucky to get 24 hours. I know the system will have an extra load (even though the memory is non volatile it still has to page the card to work out it's status) but can anybody explain and / or reproduce it with their phones?

To quote Paul from a PM

In-bloody-credible It lasts much longer. You are not going crazy!  

Got 3 bars left at 8pm instead of 1.

Thoughts?

Hmmm They Should Design A Programm That Can Turn The SD Card Redining Off And Only Turns it On when you use your phone or somewhat in that direction.... Maybe It's a Idea... :?: :?:

Well It Looks Logical To Me That if you connect a hardware thing in your spv( In this Situation a SD Card) That It Drains Power just as if you put a PCMCIA card in your laptop it drains more power because it constantly Gets date But Because you dont always need to acces date on your spv maybe it can be turned off and only turned on when you use your spv

For the Orange issue, I think it isn't their problem because it is your choice if you use a sd card or not, and it isn't somewhat of a bug ....

Good spot guys. So basically the phones power is being drained because the software constantly searches for any 'add on' devices? So someone somewhere just has to stop this searching function and make the card in an 'on & off state' and not a constantly on state.

:twisted:

hmmm...good point. but i am sure there is something with the software that can be modified, there has to be. I say you could possibly organize some sort of an official test, maybe have a few people in on it...

Hmmm I'm No SPV Smartphone Tweaker But Maybe It Is In is Mentioned in the registry how much the sd card is updated... :?: :?: and maybe you can put this number down...

Should ask a moderator or somewhat they know more then me :)

Well I Think It is Basiccly in the Begin part of microsoft but it isnt somewhat of a fault it is just a logical thing that your sd card is updated

But Maybe that can be tweaked

interesting- veeeery interesting!

i have the smartbatt-plugin running and here is my experience:

i have akku running at 88 %. with the 256 mb sd card it tells me that i have energy for another 15 hours. after reading this here i took my 128 mb mmc card, copied everything from the sd to the mmc and put the mmc in the e200. now i have still 88 % akku left - and 1 day 55 minutes to go with the akku...

so, whats the problem? it would be possible to disable the card completly here HKLMDriversBuildin but who could want that?

cheers, lutz

Thats a Start, Maybe Some One canb Get From This to something that Puts the card out after 10 minutes of non usage for example should give you a enormous battery boost in compare to the constantly use of the sd card

The only thing now is Is It Possible to Make Something for This, And Does Someone Wants To Do it (Hopefully Someone Does :) )

ok, more data for you.

all numbers taken from smartbatt plugin, voyager runs with bluetooth on:

86 % akku - no card - 1 day, 3 hrs., 40 min. left.

85 % akku - mmc card - 14 hrs, 25 minutes left.

85 % akku - sd card - 14 hrs, 24 mins. left.

so at the end of the day the difference between sd and mmc is non existent but the difference between card/no card is massive. its not bluetooth that sucks your phone off its the card!!!

there is a tool in the windows folder of the voyager called SDCARDBusControl.exe (BSQUARE 2002, Shutdown utility, Produktname: SDIO). with some tricks we where able to use the parameters - x (shutdown SD Bus driver stack), -m (output current memory state). too bad: shutting down the card bus locks the phone completely, no input possible anymore. the smartbatt plugin shows massive increase of the standby but what does it help when the phone is locked up....

as far as we can see there is no workaround to fix that problem beside the option to take out the card if you dont need it. oh boy, thats poor work i have to say. we pay with battery standby for the nearly non useable feature of the sdio-slot...

cheers, lutz

@ pisquee: definitly not since this problem goes back to the fact that htc implemented the sdio-controller in to the e200 and that wasnt there in the spv/e100. we already checked that out to see the difference in both card controllers. its simply something someone forgot and its clear that it goes back to htc. thats why its pretty needed to tell this mr. orange ...

btw: i have my e200 running now since 2 am with bluetooth (was on 85 % battery at this time) on and no card in it. it seems like i am good for another 13 hours (40 % battery now), so i am shure that i can go 24 hrs with bluetooth on and card out...

cheers, lutz

Woohoo! This is the fun of owning an SPV :D Much more interesting than your average phone.

Poor bluetooth getting the blame for everything. Come back bluetooth we're sorry :)

I'm glad i've finally contributed something worthwhile to this forum! Hopefully this is something that can be fixed with a software update, i need to use an SD card but i also need my phone to last longer than a day and dont want to be popping it in and out all the time!

Very interesting indeed.

A thought. The SD card doeshave a LOCK feature, meaning you cant write anything. Would having the lock enable be a way for the phone to stop searching (or whatever) because there is no card technically to write to?
