Last weekend I upgraded my P910i firmware to the latest version (Organiser R2A17) and put in a 512mb memory stick pro duo.

Previously with older firmware and the 32mb card which came with the phone I had managed to run easily for 2 days on one charge (and once for 3 days) with normal usage.

Now I take my phone off the charger at 7am and it is dead by lunchtime. So it's dropping 20% per hour!!!!! That is without using the phone at all, with no apps running (using sman to flush), powersave on, 25% display brightness.

I suspected the battery and tried another one, but with the same results, so it's not the battery.

I just tried taking the 512mb card out a couple of hours ago and it is dropping about 1% per hour, which is great, so it seems that
either the memory stick power consumption is just very high and this is normal (I doubt that, see below)
or the memory stick is faulty
or the new firmware is faulty and doesn't put the card in standby properly
or the card socket is faulty (or dirty)
or there is some software on the card which runs a power hungry process I can't see with sman
or...I don't know

Does anyone know of any issues with any of the above?

I looked up power consumption figures for the card -- 100mA max, and 300microamps on standby, so with the 1260mAh battery it should run for 12.6 hours even at max and I believe it should be in standby most of the time (is this right).

What power consumption do you get, and what size card and firmware do you have?

My it certainly sounds like you’ve done your research on memory cards.

My only suggestion for the card would be to perhaps clone it to another card of da same size (if you have on) and try it instead. Although if it was feed more power wouldn’t it sorta become damaged?? (I don’t know I can only presume it would)

Neways I recon its software based.
Perhaps you have a process in a continuous launch procedure. I use taskman and I am able to see the system processes as well as programs running.
On the odd occasion when I run a certain program I do notice a process by the name of “Alaunch” or some thing like that continuously appear and disappear on the taskman list. Perhaps you have the same problem. Although when this happens I do experience extreme slowness.
Other then that I don’t have a clue :S

As 1tuf4b said you might have processes still running in the background which is causing your battery life to drop. Install Sman and kill use it to kill off an tasks which you dont need at that time and see if that yields any positive results. u can get Sman here

Thanks both of you for your suggestions. I do use Sman already as I said, but didn't manage to spot the rogue process if that is what it was.

I tend to agree with you that it was software related. Anyway, good news: when I removed the card the power consumption went back to normal as I said, and when I restarted the phone and inserted it again it remained good and the problem I had for 5 days seems to have disappeared! I had restarted the phone several times before, but had never tried removing the card. So removing the card must have disrupted the process causing the problem. Or if it was due to a funny hardware state it reset it.

hmmm! that seems a bit strange sort of behaviour but i guess at least its working as normal now and saving you a huge headache
