Maximizing battery life on your device

My definition.

For me, "normal reading time a day" for a full-time working person would be something like 1-3 hours a day, with an average of 2 hours.

For me that would be a level where the light is just a bit brighter than an everday environment such as a living room during the day or evening.

I understand there are always people who are way above or below average with regard to reading times and front-light usage. I do think, however, that the number of people reading 15 hours a day in a dark room with the front-light set at 100% is quite low

Front light. There is no back light.

Oh ok. Not everyone works full time. There are many disabled and retirees that have devices. Not to mention the domestic engineers whose children are grown.
Alas, there is no normal.

I could never read with the light set even at 50%. The highest I could go if I had to would be maybe 10%.

No one said anything about 100% brightness for 15 hours. I commented on hours of read time. Desk commented about brightness.

People should set the brightness at what is comfortable for them. For me, that is low. For my husband it is about 50% or more.

Now is someone is so worried about the battery life that they will turn the light down so low that the device is almost unreadable, they should sell all battery powered devices and read paper.

Look I rightly don't give a rat's behind what anyone thinks is normal.
There is no normal usage on a device. They can figure an average.
Average does not mean a person.
It means you take the low end users and the high end users and everyone in between to get a rough idea of a time frame of a battery or anything else for that matter.

I have always had trouble reading print books because of how much light I need to read comfortably. Even with good table lamps there were shadows etc. to deal with. The Oasis is front-lit, and having the light all the way up when reading in a normally lit room doesn't bother my eyes at all. It is that light that makes it possible for me to read for hours per day. I love the sharp contrast that the light gives.

In a dark room, I have the light at 10-12 to start with, and turn it down as my eyes adjust to 8-9. That is in a totally dark room.

Even as a young person, I needed a LOT of light to read. I'm pushing 60, and have worn glasses since I was 5-6. I wear a Progressive lens now, and can read the Oasis at night in bed without my glasses with the screen 7-8 inches from my eyes.

Once something is past 12" away from my eyes, without correction I am legally blind.

Thank you for this information. It is appreciated.

I open and close the cover on my Oasis numerous times per day, some days 15-20 times. I'm sure that effects my battery life also, the multiple wake-ups with the light all the way up.

I plug it in every 5-7 days on average, when it gets in the 15-20% range.

Aren't those 2-3 week times that are advertised for eink readers based on reading some fairly minimal amount like 20 or 30 minutes a day? I've never gotten multiple weeks on my Sony readers. I usually read at least a couple hours a day, sometimes more, especially on weekends. Don't know the maximum number of days I've gotten on a battery charge but I am sure it was never as much as 2-3 weeks.

Yes, it is based on 30 minutes a day read time.

My usage is so different. Even with the Kindle Paperwhite.
Yes, we buy a reader with backlight, for easier reading.
However, I find I can read the text just as well without backlight, as with backlight; and saving battery in the process.
In a normally lit (office lit) space, 350-500 lux, I find I don't need the backlight at all.
At brighter settings, I might even go night mode (white text on black background) to save eyeburn.

I find modern e-ink screens, pretty much equals regular paper.
Back in the day, recycling paper; nowadays, it's pretty much on par with most broken white paper from library books, or books created in the past decade; not the brightest white printing paper yet, but good enough to read without using any sort of screen light.
Perhaps the only difference, is a bit of light reflection and fingerprints; but otherwise pretty much identical!

I only use the screen light when the room gets darker, like candelight dinner (25-250 lux), I might use setting 1 or 2.


When my wife is sleeping next to me, in a pitch black room, I do dial in the Oasis to setting 3-4 tops, but can still read it at level 1 to 2.
I like that I can put the reader so dark.
Unlike with eg: tablets, where she wakes up from the light emitted from the device.



Ps:
So far, my Oasis has dropped 10% of battery per day, with only minimal reading.
I believe just keeping it standby, the device won't last 2 weeks; but I haven't taken it that far yet.

Oh it is a front light not a backlight.
Just because you can turn off the light doesn't mean everyone can.

Like I said before: while your ideas technically work, they are not for everyone.

Did you really think everyone was going to do all of your ideas?

Nothing is saving my Oasis LOL it seems to be a battery hog. Turning off everything does help but I usually cave in and up the light level a bit. Anything lower than 15 seems too dark in daytime

Reading during your candlelight dinner. You romantic, you!

Daytime I usually have enough light in the room to not need the light on at all. Between the lights in the room and the light from the windows I don't have a need to keep the light on. I mostly use the light at night in bed.

Gives a natural yellowing of the page, which is nice to fall asleep
