My Jamin just slept to Death...

---

Had it at about 70% battery (around) last night, after 12 hours or so today, it refused to turn on.

I got it to turn on finally with a soft reset, and the battery showed 28%!!

I have no idea how it could have run down so fast, though it could have been something I left on (maybe wifi?).

I'm still surprised it would refuse to turn on at 28% though...

My Dopod 818 Pro is having this problem ever since I bought it. If I turn off the screen using the power switch or let it go to standby automatically, most of this time I can't turn it on again and have to do a soft reset.

I do not see a lot of Dopod users complaining about this problem so I am wondering if I have a faulty set. Other than this problem, everything else works fine.

i'm having the same problem. Do you think there will be a rom fix?

I just found an interesting observation regarding this sleep-to-death (STD) issue. If I left my Dopod overnight and got the STD problem the next day, the battery had drained considerably. It was fully charged the night before, but after 8 hours, the battery is only at 40 percent.

But since more than one person is having this issue, is it still a hardware problem?

This is not a hardware issue, its more like an unoptimised ROM issue. I suppose it will be fixed with an update in the future.

Leaving WiFi on does not matter because your device automatically goes into standby mode after a pre-defined time (3 minutes by default). In that case, even if you leave 10 apps running in the background, it won't make a difference for the aforementioned reason.

With the HTC Universal, what happened was that people would leave apps running in the background and once they are done using the device, they would just close the device thinking that it would shut off, but it wouldn't because the standy-mode was disabled by most people to get a snappier device. In such a situation, battery would drain rapidly overnight as the device hasn't gone into standby mode.

This situation will occur on the JAMin too IF there is no default standy-by mode set.

I have an HTC Universal (O2 XDA EXEC) and had the same thing happen to me two nights in a row. The battery was at 100% when i went to bed and i woke up and realized i was late as the alarm i had set didnt wake me up.

I had to soft reset the phone and the battery was down to 24% and then the alarm starting going off, a bit late though. I have had this phone for three days, and im not happy about this failing twice on me.

The only thing i have changed is running a coporate install (0506) so that o2 active wasnt on the phone.

Is there any fix for this??

Rom version: 1.13.82 WWE
Radio version: 1.04.02
Protocol version: 42.37.P8
ExtROM version 1.13.188 WWE

Go to Settings>System>Power and check the "switch off device after x minutes" option. By default it is 3 minutes, but i have set it to one minute as that serves my purpose. You will notice the drastic difference immediately .

It kind of sounds like an issue I've seen on my m600. It's a wm5 bug where activesync will try to connect all the time, randomly, even if your device is off. It can cause STD (sleep to death) and will. It's a simple fix. Just install the autosyncschedule.cpf and run it. It's a simple little .cab that will change some settings. Hope it helps

If that link to my yahoo briefcase doesn't work, you can get this file at eten-users.net in the download section under /utilities/wm5. It solved all STD's with the eten and so far with my jamin. 8)

You can also fix the Active Sync bug manually.

To do so open ActiveSync on your WM5 device and tap on Menu>Add Server Source. Add any info to create a fake server sync. After that is complete go to Menu>Schedule and change the two dropdowns to "Manual" and tap "ok" at the top right.

Slept to death- I've sussed out why my device was doing this

I had an SD card from my i-mate Jam inserted, and after taking this out, the situation stopped happening. So if you've got an SD card in try running the device without for a while to see if that helps...
