Maybe Kobo is preparing to add ads! Oh noes!

Nooks have had swipe to open for a long time without ads. I always assumed it was because those were based on Android though. And people figured out ways to turn it off -- at least with the older Nooks...haven't paid attention to what people have done with the Nook 3.

Well, I guess that explains why I feel the battery life on the KA1 is really good. I hardly ever use the light, but leave wifi on. Haven't checked times, but never noticed any big difference between it and the first H2O or the Aura HD before it. My Oasis 2, on the other hand, seems to need charging a lot more frequently when I'm using it compared to other ereaders.

Yes, I never use the KA1 lighting and my battery service is excellent.

And yet, my battery on my KA1 lasts very well, similar to other devices, and definitely nowhere close to half the time of previous devices. (And I have the light on all the time, usually in the orange spectrum, use nickel, have wifi off all the time)

I was mainly objecting to the previous poster's statement that another person was plain wrong. Not that no one would experience such a difference in battery life.

As you did, giving your own personal experience is useful for others to gauge the general experience, stating that it is definitely that way for everyone, not so useful.

It's a well known property of the A1, and was even reflected in Kobo's own specifications back when they used to estimate device time in number of weeks based on 30 mins per day use.. Your the only outsider really making a claim to the contrary.

Whether or not the shorter battery life is an 'issue' is an entirely different matter. As many have said, 15 - 20 hours is more than long enough to get the job done,, and if you aren't stopping for at least 1 shower break in that timeframe, that's probably a bigger issue.

I got my Forma and sleep cover on Thursday and I can confirm that there's no swiping that needs to be done. When you open the sleep cover, the Forma turns on immediately. The cover is really nice and seems to be pretty sturdy. So far, I'm very happy with the Forma--very light and easy to hold, the screen is large and very bright and everything works really well with Calibre.

I have similar experience with battery life of my KA1 as Uschiekid. i don't find nothing wrong with it.
I do use screen light and wifi is always off.

I think you have completely misunderstood me. I was defending another poster who was told they couldn't be right, when they said they had a different experience with their battery life. I am not claiming to know more or even claiming KA1 battery life to be anything specific.

What I am trying to do is say that without rigorous testing (which Alan_S did not do, by his own statement after his first claim), he was simply stating his *experience*, and it should be worded in that way.

I am not the only one who has experienced good battery life on the KA1. And I am certainly not coming in to this discussion "as an outsider" to "claim to the contrary". I have no interest in making any such claim. I was simply stating my experience, and trying to get everyone to acknowledge that they too can only state their experience.

It is not only mine experience.

I read posts here from people who don't use koreader and use only nickel. And, who had H2O before and switched to KA1. They first reported smaller battery, reduced battery autonomy.

These people's reports where pronounced as false, I just chimed in and said that these reports are similar to mine and that I noticed that my devices act according to these reports, i.e. KA1 has half battery life from H2O.

Of course, I understand that people who have only KA1 may think it is not so, but it is so. KA1 lasts much shorter than H2O (i.e. half the time). It is simple fact, anyone who has both devices can check it after some time (testing in real life reading conditions takes time, weeks, even months).

KA1 has about half battery life of H2O. I know, you mentioned HD, I don't know about it, but KA1 works for me about 5-7 days, H2O worked (or, still works, but I know use KA1 mainly) 10-14.

This is what I object to. I don't doubt your experience, be kind enough to not doubt others' experience.

7 seconds is time till H2O (device that was actually tested and has IR grid for determining where touch happens) goes in some deeper sleep state while still being on and waiting to serve next page.

Also, why 7 seconds, is it spent the whole time on rendering next page? Probably not, but it is 7 seconds.

Also, when talking about rendering, it is not that you wait 7 seconds to see next page. Process is:

A) You read page and touch display to have next page shown.
B) Next page is shown. You start to read it
C) 7 seconds after page is shown reader is in a state of a heightened activity, i.e. spends 13mA.
D) After 7 seconds reader goes in a deeper sleep state and reduced 1mA battery usage, which lasts till next touch.

With koreader device stays all time in 13mA battery usage state, while you read.

Hope it makes things a bit clearer. What exactly goes on within 7 seconds certainly isn't just rendering page, but also probably some "housekeeping" by nickel.

And yes, this measurement is actually done and reported on koreader's github page, where I get this info from.

So, nickel probably is a bit energy efficient while reading, but not that much and it certainly depends on many factors how much time you save with nickel versus koreader, but I'm pretty sure not that much it is that big issue with using koreader.

I did testing with my devices. And yes, battery lasts much shorter.

For rigorous testing I should have numerous devices, which as private person I don't have and don't have access too.

But, there's specs reported by manufacturer and experience from many who saw same thing as I do.

There always seem to be some people who don't know what facts are and don't want to believe in them and people who know facts (or just notice them). And thus call them names (i.e. that they are malicious).

It is funny that way. But, KA1 has battery as it has. And yes, I can understand that it can be enough for some people (5-7 days reading between charging can be "a lot" for some, but still, as I know that I had (or still have, if I switch back to H2O) 10-14 days with H2O).

There's no mystery, just smaller batteries. Or, maybe better to use

That's all I was pointing out. Be rigorous when stating absolutes.

I disagree with many things you've written, but to be honest, since I tried to explain my point of view and you ignored it, I'm not going to keep arguing.

Aaaahhh that makes a lot more sense. Thank you for elaborating on what you meant! Interesting

I say battery life varies a lot even with the same model.

I've always been impressed with how long my KA1 lasts. As I said earlier, my previous readers were the first H2O and before that the Aura HD. I definitely didn't see a serious drop in battery life. I feel like I have to charge my Oasis 2 a lot more frequently. On both, I leave wifi on, but rarely use the light.

My husband has both devices as well, and his experience is the exact opposite -- short battery life on the Kobo, long on the Oasis. He keeps light and wifi on with the Oasis. On the Aura One, he uses the light, but keeps wifi off in an attempt to make it last longer.
