If turning the light on and off makes a difference in standby, then your cover might be defective. Try to leave it open and put to sleep with the button and light on, see if it still drains. |

Obviously you only turn the light off like this if you know you're far from power: otherwise, halving the battery life is an acceptable tradeoff for the nicer screen quality the lighting gives you. |

I just crank the light level up to my usual reading level , about 12-15. It does use up the battery more, but I just charge it more often. I still like my Oasis 2 , but I would have loved it a lot more if they put in a larger battery. How much heavier would that have made it ? Not a whole lot. The next Kindle Oasis or what ever, I'll check the battery to see if it's bigger, then decide to buy based on that.

Again, its not about days, its about how much one reads. I read a lot, no kindle will ever last me 10 days, unless they make one with built in solar panels or find some new fandangled battery technology. Voyage and O1 I got 4 days of batter, O1 I get about 2.5 or so. Same reading pattern. I read at #4 and use #3 bold. So I use a bit more. But in the end, its the amount of reading I do. It wouldn't matter if I never turned on the light, it would still never last me 10 days. Unless I am in a coma. ![]() I get easy though 10-12 hours on a charge, on all of my kindles. Its more like 20 hours with the O2 and closer to 30 I think on the Voyage. My O1 lost the ability to now hold much of a charge out of the cover. It used to be 7 plus hours with light, now its like 2 hours, if that. Its why I went to the O2. The keyboard I think still has the best battery overall. But no light makes it a no go in the dark. I can put that thing on the shelf and its still charged full a month later. But even it, when I used it full time, never gave me 10 days of battery. Cause again, I read and read and read ![]() |

Battery life depends on how much you read, if you keep the wifi or cell on, and the level of your lighting. I have not had my Oasis 2 long enough to gage its true battery life. But there are some very cold wet days here that I will read as much as 8 hours in a day. and I know I can read for at least 2 8 hour days with on charge and that is as good as my Voyage or PW2 would do. do not leave wifi on. and I keep my front lighting low.

Sounds like a problem in the firmware. The Kobo Aura One had a similar problem and it was a firmware problem that's now been fixed. I think Amazon either needs to fix the firmware or it turns out ot be a hardware problem, fix the hardware and replace all the previous version with new ones.

The Kindle Index gets progressively slower the the more books it processes. It's always been that way. The Oasis 2 has been noticeably better in that regards, either to to the hardware specs increase, or improvements in firmware, (I haven't really been testing this exhaustively.) However, even with the Oasis 2, if you dump hundreds of books on it, re-starting every 4 hours or so will get through the indexing much faster.

Check the ~DS drain issue (enable the screensaver for BETTER battery life, not worse) posted about here:
https://www.mobileread.com/forums/sh...d.php?t=294177 I don't get the lousy battery life most of you get out of my Oasis, although I find the battery life still too short for me. I think there's some truth to the fact that every time you sync the device, it's best to just plug it in the AC. That way the indexing goes faster. When I preloaded my first 600 books on my device, the battery dropped 10% per hour, so I left it plugged in for about 30 minutes. The indexing mostly only get done, when new books are added, or maybe when booting the device. After that, unplugging is ok. I would also agree, that carrying 600+ books, isn't really the best; and would agree with CVKemp, to just load no more than 100 books on it. You can always sync the other books to the device. It takes quite some time to process 10 books, even for a fast reader, let alone 1000 books! I turn off the wifi (airplane mode) as soon as the syncing was done, and I never read with screen light on. It gets me about 2% per hour of battery consumption on Kindle books, but double to quadruple when reading PDF documents. The Oasis' screen has sufficient resolution to display A4/Lettertype PDF documents, but the size is still too small (the characters are too small on screen), to comfortably read a PDF file. It's like setting your font size to 0.25 (well below the lowest setting for kindle books). Last edited by ProDigit; 01-23-2018 at 05:47 PM. |

Last night I forgot to switch the wifi/3G off and it only drained around 3% overnight. (Might be less, I didn't check the number before falling asleep.) So today, I'm just going to try using it normally, and forget about the whole battery issue. For me that means pretty much light at 14, bookerly font at 4 (sometimes 3). I'm also going to just leave the wifi on. I'm at 85% now (lost one per cent in the last couple of minutes!), so let's see how long it lasts. (I haven't even tried to load any more books onto it yet as I'm hoping the whole battery issue settles down after a few more weeks of use.)
