Fascinating. I had been noticing pretty pathetic battery life myself. After the initial indexing, I'd had to fully charge it from under 20% probably three times in the last two weeks. By the way, I'd owned the original Paperwhite and also the Voyage so I have a feel for how long it should last (I definitely noticed the Voyage needed to be charged more often and definitely definitely noticed the new Oasis needs it more often).
Firmware: 5.9.2 Wifi: Off always Light: 11 (not automatic) Font: Bookerly Bold: 1 Size: 2 Indexing: Fully indexed Cover: Amazon cloth cover I would say about 8 hours of reading has been consistent with my observations. That being said, I did a test today where I read for an hour (didn't leave the book, no highlighting, probably about 80 page turns) and went from 24% to 20% battery. That should equate closer to 25 hours of battery life. But that definitely hasn't been my experience. I'll keep an eye on it, perhaps I'm draining in between reads or one possibility may be that the cover makes it turn on and off while carrying it in my pocket. |

The only font controls on my Kindles (basic 2015 and Voyage 2016) control the fonts for books/docs or a separate one for pdf's, but not the UI, i.e. the library home screen in list mode. Both Kindles are now on 5.8.11. I don't have an accessibility option in settings. Is this something exclusive to the new Oasis or firmware newer than 5.8.11? If it's a question of FW, can it be applied to the Voyage? One of the only complaints about my Voyage is that the fonts for the experimental browser and library list are too light. Even the Basic has a bolder UI font. I actually read articles in the exp. browser and if I use article mode, the font weight is excellent, but article mode only guesses at what text it should display or ignore and often truncates real content. Most articles in "web mode" are unreadable on the Voyage and borderline readable on the Basic. Being able to change these fonts would be major. |

Atunah,
I did the test using your settings (bold 3, brightness 10, WiFi off, font#4). After 209 minutes of reading, my Oasis is at 90% battery life, a stunning improvement. That extrapolates to 34.83 hours battery life, exponentially better than the 7.4 hrs to date, and exceeding Amazon’s specs (42 days, half hour a day, brightness 10, wireless and Bluetooth off). . I am going to go out on a limb and assume brightness level was probably the major source of battery drain. Hopefully it wasn’t the 4 pt font! So I will keep the Oasis. My big concern was having to carry a charger on weeklong trips. Now I can safely leave the charger home, as long as I keep the brightness down. Cheers, Joe |

Of course its important if the light setting works for one. If I read outside, which I haven't done yet with my Oasis, I can probably turn off the light all together as I don't see it anyway on sunny days. |

But I can't use it anymore. It constantly goes up and down as I shift while reading leaning towards and then away from a lamp. I just got tired constantly adjusting it. And 10 works all day for me, inside that is and I go to 8 in bed. If I ever sit outside, I'll just turn it off. |

It does, but when the light gets so bright that the frontlight can't "compete", it'll turn off. At least that's what the Voyage does, and I've no reason to suppose that the Oasis will behave differently. Unfortunately at this time of year in Britain I can't test that!

I held my Oasis, and Voyage up to bright light bulbs before, to teach it my levels and it just goes up to like 18 until I put the breaks on. Haven't seen it go all the way. But the constant training drives me nuts and mostly its the shifting when the light source falls differently on the screen. Even if its just one level, it goes up and down and up and down. I guess I am a fidgety reader. |

Thanks for confirming that; as I say, there no way to test it in British winter sunshine, but I was pretty sure that's what it would do .

I tried a 200 lumen LED on the voyage last night, but that was too borderline to get reliably repeatable behavior. One other minor difference was the Oasis 2 turns its light back on as soon as it enters a shadow. I had to close the cover on the voyage or take it indoors to get its light back on. |

Light level does seem to be key to battery life. I turned the light off yesterday when I was reading in a well-lit room, and the battery level only decreased by 4% in 2.5 hours' reading.

What I found interesting was that when I set bold at #2, use the caecelia font and turn the light off, I can compare it to my K3 and my black basic with buttons and it looks almost the same. The basic buttons to me always had the best contrast of any kindle I ever owned. Dark thick fonts, just great. Just no light. Now with the bold option, I can re-create that page on the Oasis. Bold 2 is about the same, but I go to bold #3 and its even better. The backround on the Oasis is a tad lighter than the basic so that also helps. So during daytime near a light source, window or lamp, I have been able to read without the light, or just barely on. So not just for battery life, I actually like reading like I used to on the basic/k3. Just that my eyes are worse now so when it does get dreary and darker, I do have to go to #8 on the light. The Oasis2 charges so incredibly fast though that it doesn't really bother me. I can eat dinner and its done charging. Or any other chore. I wish my phone charged that fast. |
