Rated standby battery drain
Hello,
I was wondering if there's an official/rated battery life when the Kobo is in standby mode with the just the logo on. It should definitely use some battery but it should be a very low power that should last several months if not a year however I noticed that when unused it could easily drain to 0% in a few weeks. Maybe there's some other background process going on? |

For all my use of Kobo devices, that's one question I cannot answer. And it is basically because I can't leave them alone long enough to get a meaningful answer. The best I can say is that last Christmas, I did leave a couple alone for about two weeks. They would have started with full batteries, and still had plenty of battery life when I got them out after the holiday. Probably in the 30-40% range. I didn't explicitly look, just remember that I didn't need to hurry to charge them. These were also the older devices, which are starting to show the effects of aging on their batteries.
The thing I didn't do before this, was to turn WiFi and the background sync off. With these on, it would have woken each day, attempted to do a sync and then gone back to sleep. It the time, they wouldn't have synced as they weren't near the WiFi that I usually use with them. If the battery is in good condition, my guess would be a "few weeks" with WiFi on. And a lot longer if WiFi and the background sync is off. |

I've had my Aura 2 last 6.5 weeks untouched at the home screen on standby with WiFi off.
