Wait, for everyone having issues... may I ask how much you've changed the Kobo from stock? 49kat's probably not had a chance to delete apps from the Kobo, but what about the others who have rooted?

For the record, my Kobo Vox is my second one - the first died mid-upgrade and had that battery not showing issue that was fixed with the firmware update. I only changed out the launcher to Launcher Pro, I've frozen Rdio, the INQ widgets, and all the stub programs like the Twitter stub, the Gmail stub, the Youtube stub using Titanium Backup. I've rooted the device, and run only one home screen with the Kobo Mosaic widget, Widgetsoid with two widgets (an Airplane mode one as well as a Battery/Wifi Settings shortcut one), and Beautiful Weather. I've also installed Perfect Viewer (which runs at startup), and don't use a live wallpaper but have installed other PDF reader apps as well.

During the firmware upgrade I was connected to my home WiFi, was plugged in, and had previously rebooted twice to fix a wifi issue (wouldn't load the drivers) as well as to unroot and remove the exploit. I let the Kobo tell me there was an upgrade available, downloaded it and ran it from the Notifications menu, then let it restart and watched it go to 75% before it reset itself again, and told me with a popup window that the upgrade had completed successfully. Just to be safe, I also checked the About Kobo Reader settings.

Since the firmware upgrade, I've only had to recharge once (it went the weekend without charging, dropped 40% from two hours of reading, and froze once when being unplugged from USB for a few minutes after I dragged some PDF files onto the external SD card), and only had to reset once. I've never had it fail to come out of sleep yet, although I do turn off WiFi or run it in airplane mode when I'm not browsing the web or downloading something from the cloud.

Today I let it go eight and a half hours unplugged and in my bag, and was still able to turn it on afterwards without any battery drain to speak of (it hasn't dropped 10% yet). This was after opening up the Kobo App to do some reading (which previously caused an freeze the next time it went to sleep). The first time I lost only 10% in 24 hours of standby along with 30-40 minutes of reading and browsing the internet.

What's the difference with these other systems? Are there live wallpapers causing problems? Is it the Advanced WiFi Lock or some other service which starts automatically? Are there any commonalities between software installations and system issues, or is it hardware based?

No wonder the Kobo Vox has had several bad reviews, given how much troubleshooting has happened on this forum... which is a shame, as the screen's lovely and it's nice and speedy when you don't use the Gingerbread Launcher and freeze the useless INQ services.
