Battery drain when off?

Avenger · 06-10-2009, 12:44 PM

I was pretty positive that I turned off my DR last night. It was 75% last night and I woke up today and I had to recharge it fully. Is there some kind of bug where the tablet doesn't shut down properly? Anyway to check this? I think someone mentioned a bug like this somewhere. Could it be because of an open document?

Yes, there's a bug that causes it to sometimes not shutdown correctly. One of the theories is that a document is not closed all of the way during the shutdown process, and it gets hung even though it looks like it turned off.

I think I've seen someone mention that a way to test to make sure it's completely shutdown is to press one of the buttons and make sure it's light doesn't react. I've heard less people complaining about it since the 1.6 firmware, but I don't know if that's due to anything iRex did in the software to minimize it or if people are just aware of it now and therefore aren't talking as much about it.

I haven't had any such issues since 1.5 firmware.

The trick with previous version was to "remove sd card safely" before shutting down the device.

Thanks for the idea. I'll try it if I have the problem again. So far I have had the reader a week and I am quite satisfied with the performance of the device if you work around the bugs. These are the ones I've found:

1. Paging through many images in a folder and closing down each document as you move to another folder seems to cause a memory leak which eventually leads to the UDS process crashing. (Thanks for Grim, I have the workaround to not explicitly close the documents.) That is an easy one...

2. In landscape mode when viewing a pdf, when the device goes to sleep(pause on a page for like 20 secs.), the left and right side of the screen can mismatch when you turn a page by using the capacitive buttons. You can work around by turning power saving off or flipping the page again quickly.

3. The capacitive buttons can lock up (the LED button will stay lit). When this has happenned, you can turn the page by stylus or reset the device. I tried turning all the sensors on and off but reset was the only thing that worked for me. Doesn't happen often enough to be concerned.

4. The battery drain problem when the unit is off which we just discussed.

These are the ones I found using the device for a week under firmware 1.6. The only one that could annoy a lot is the battery drain but I am hoping it is sporadic and I can use the "remove card safely" if it happens more often than I would like.

I had an order in for a Kindle DX but I cancelled it since right now I am satisfied with the DR.

I had this problem even with firmware 1.5
One solution suggested was that after the reader turns off, you check that it is really off by pushing the side buttons. That is what I do now. Since I started doing this procedure, I did not have the problem. On the other hand, I also didn't encounter a case when the buttons indicated that the reader was still on....

Do you mean it is possible that the lights could be on when pushing them even the device has been turned off? I mean sometimes....

If that happens, I think it means the device did not shutdown correctly.

O, dear......interesting

I've not encountered this issue personally. Perhaps it's been fixed in 1.6?

yingwu · 06-13-2009, 07:16 AM

I notice the irex has done much homework on the firmware. Any information of 1.7??

I have never seen it happen. All I saw is a DR full when turned off, empty when turned back on in he morning. Someone suggested to test the buttons, so I'm doing that now... but I never encountered a case when the buttons did indeed light up when the device was off....

So why to check to test the buttons to avoid the device is out of power in the next morning? there must be some sign.....

I have not seen any announcements for what will be in 1.7 yet. It usually takes a little bit of time after a previous release before they narrow down the priority list and identify what features/fixes will be included in the next release.

Superstition. Since I started doing that, my device was never out of power....
