c) 6 hours read per day
d) I only care about the small battery
This is what I came up with:
After the first year, Capacity is down to 7.8 hours (and went through 260 cycles)
After the second year, Capacity is down to 6.5 hours (and went through 563 cycles)
After the third year, capacity is down to 4.7 hours (and went through 960 cycles)
I may be completely off about this.  |
As math is not my thing, what about if one only does a full charge when one charges the cover and the device. And even then, my Oasis usually is pretty full, I charge when my cover gets low. How does topping off a battery here and there wear on a battery compared to full charges, like I used to do on Voyage and any other kindle.
Looking at those numbers though, not anything for me to worry about.
I always had to charge all my kindles every 3-5 days when I read regularly. My K1 I used to have to charge a lot more, at some point I had to plug it in while reading.
. My K3 probably did get the best life, but it has no light of course. My basic screen is about as good as my K3 and its battery lasted me nicely too. But again, no light for my bad eyes. I still use it at times on the balcony. Those would get a week I say for my reading pattern.
PW1 had horrible battery, had to charge ever 2 days. Voyage (wifi on always) every 3-4 days or so if I read a lot, 5 days if I read a little less. Oasis every 5 days.
I read on my Fire6 for a while when I had to read on apps and I had to plug it in that same day.
My Oasis gets a tad more life than my Voyage, I am happy with that. If the battery life of the Oasis is compromised 3 years down the line, I don't think that will be a big deal. By then I will probably already have whatever new thingie kindle comes out.
