Here lately a number of people have been asking about the battery life on the new Kindle Oasis 2, but I’m not quite sure what the answer is, even after several weeks of using the device.
My problem is I have too many ereaders in use at the same time to get an accurate feel for battery life.
I read on the Kobo Aura One for awhile and then get bored with a book and switch over to a different title on the Kindle Oasis.
Then I read on it for a few days before switching to something else.
I’ve been trying to use the Nook Glowlight 3 since I was supposed to post a full review a month ago but still haven’t gotten around to it (I like the Nook but it’s no match for the other devices I have around).
Amazon says the battery on the Kindle Oasis 2 will last up to six weeks per charge when reading 30 minutes per day with wireless turned off and the frontlight set at ten.
That’s the same exact battery life claim as the Kindle Paperwhite 3, so in theory they should be about the same.
Having wireless turned off definitely has a big impact on battery life, so lots of people keep airplane mode turned on most of the time. The only problem with that is it limits the use of certain features, like Wikipedia lookup and translations.
At first the battery went down pretty quick when I got the new Kindle Oasis, but it seems to have leveled out over time. It still seems like it might drain a bit quicker than the Kindle Paperwhite but without doing extensive, repeated tests it’s hard to tell for sure.
I’ve gotten somewhat used to shorter battery life with the Kobo Aura One. Its battery lasts about 15 hours or so between charges. From my experience the Kindle Oasis 2 seems to be about the same.
What about you? What’s your experience been like with overall battery life on the new Kindle Oasis 2?
I’m getting 12 hours on my Oasis2. WiFi off, frontlight at ~18. For me, it seems every advancement of the Kindle brings decreased battery life: The PaperWhite 1 was (about) 25 hours, PaperWhite 3 ~ 22 now this.
My Aura One 8GB got ~ 18-20; the newly-arrived A1 32GB seems a little better but it’s too early to tell based upon 4 hours of use.
That’s one of the reasons why I never want to see an ereader with higher than 300ppi. Too little gain at the cost of battery life.
I don’t know exact times, but it certainly seems like battery life on my Oasis 2 is much shorter than my Kobo Aura One. I keep wifi on, but I seldom use the light on both.
I’ve been happy with the battery life on mine. It went down very quickly when I first took it out of the box, but I attribute that to setting up the device and adding all my content back onto it. Plus it only had around a 56% charge when I got it anyway.
Did a full charge after that, and just did, I believe, my second full charge last night. Still had about 30% battery life remaining, but I was doing the newest firmware update anyway so I figured I’d throw it on the charger.
Kind of hard to judge right now, but I’d say its been better than my gen 1 Oasis, but maybe not quite as good as the Paperwhite 3 I had.
So far I have no complaints.
Compared with my Kindle Voyage I don’t see much of a difference.
Sure, if you download a whole bunch of books every few days the battery drains rather quickly, because of all the indexing and stuff.
But I read quite a lot lately and I would estimate, that you can easily read two to three mid-sized books without worrying about the battery at all.
Seems the same as my Voyage.
Getting about half of my Voyage, plus seems to hang up quite a bit, especially with the share option.
I charged it sunday not its friday and 80% battery drained with little use!!!! And on airplane mode and brightness between 10 and 13 I barely used the thing too. i am so mad at the battery drainage
That’s not normal. You should check to make sure a book isn’t stuck indexing. You can find how at the bottom of this article.
I keep the wifi and blue tooth off. There are hundreds of comments on the internet from people with the same battery life issues.
I purchased the Oasis about 10 days ago and already it is ready for its third charge. 6 weeks is false advertising In my opinion. I get less time than on my Kindle which I purchased many years ago.
bestbuy deleted all the negative battery reviews
I’ve been v disappointed with the Oasis. This is my third attempt ie replacement. Despite leaving airplane mode on and low light I was only getting a few hours reading time. Haven’t had chance to test this third one properly yet but I’m not hopeful.
I want an e-book I can travel with and not have to worry about charging after every 4-5 hours reading My old paper white gave me that.
exchanging will not help they all suck. I loose 6 to 12% a day on 30 minutes to an hour reading
I have been disappointed with the battery life on my Kindle Oasis. I do use it a lot, but I thought this one would be better.
What really got to me was the cover that gives it extra battery. Call me crazy, but I thought you would be able to charge the cover separately, so it could sort of act like a power bank, and then put it back on again. Hence you would never have to stop put he Kindle down to charge.
I think this is really stupid design.
My Oasis is coming up for 2 years old, and I am suddenly getting about 4 hours, before it shuts down completely. I checked the last charge, showed 100% in both batteries. This is an expensive shock to me, the whole rationale was the quality angle. This indicates poor quality. I will turn the Wi-fi off.
I purchased the Oasis in January 2018 and used it about 1 hour a day. The first month I had to charge it every other day. Talked with Amazon and they finally said it was a defective device. Just got the second one and although Wi-fi, bluetooth and lights are all off or down, I am only getting about 2 days of battery life when reading no more than an hour a day. I am extremely disappointed with this and will be returning it for a refund. My Kindle Paperwhite which is several years old holds a charge for 3 to 4 weeks using it the same amount of time.
Are you sure it’s not stuck indexing? There’s no way the battery is only going to last for 2 hours otherwise.
I’m also on my second one and the battery isn’t any better. I’m going to return it and go back to a paperwhite.
I like the oasis, but I dislike that I have to charge it about every two-three days.
The battery life is abysmal on the new Oasis 2017! I read a couple hours a day, and I’m charging the new Oasis every four days.
With wi-fi, bluetooth, and auto brightness off, and brightness set anywhere between 3 and 5 (very low), I get approximately 10 hour of reading time, which is less than half the battery life I get on my three-year old Kindle Voyage. I don’t really play around on my Kindle; I may download a couple books a week, but that’s it.
Amazon claims you get six weeks of 30 minutes each day with brightness at level 10 and wi-fi and bluetooth off. That equates 21 hours of reading time, which is an absolutely lie. I’m getting HALF that reading at one third of the brightness.
I like the bigger screen on the new Oasis, but I think it’s going back. I travel a bit, and I can’t be stressing about my e-reader running out of battery before I even get to my destination.
The kindle oasis 2 has 1000mAh and thenpaperwhute 3 has 1320mAh. The Oasis has more LED and gyroscope constantly sensing. The paperwhite does not have gyroscope and fewer LED. That’s why oasis 2 battery drains faster.
Interesting! Do you have source for these battery capacities? Hate it when manufacturers keep reducing battery life so devices can be slimmer.
Also wish there was an option to disable the (overly sensitive) gyroscope.
I SO REGRET getting the Oasis 2! IF I hadn’t given my old Voyager to my Neice I would just say screw it. I’m a very very intensive reader. I read approx 8-15 hours a day. And I have to plug up the Kindle at about 8-10 hours. I have the wifi off the blue tooth off, the auto bright turned off. Thank god I carry a awesome battery back up in my purse for my Iphone and it will charge up to 2 laptops when the backup is full charged. I went to the 2 because it is said to be waterproof (which I have not tried) since this summer is all about my grandkids and I going to Aquatica 2-5 times a week. I lay in the cabanas and read while they go on the rides and have fun. So unhappy with this one!
I am really disappointed with the battery life on my Oasis too. I thought perhaps I had a defective one, but clearly Amazon’s claims of longer battery life are a lie.
The oasis 2017 battery capacity source:

The Paperwhite 3th battery capacity source:
http://pad.zol.com.cn/530/5300201.html
But those sources are written in Chinese. Please translate them in English or just have a look at those pictures.
Plus, according to the source, the Paperwhite 3th has a 1420 mAh battery life instead of 1320 mAh as Paul mentioned.
I have just tested the capacity of the Oasis 2, I have recorded my time spending on reading. I have to say that the Amazon is pretty accurate with the 21 hour reading. For example, in the last 3 days I read 681 minutes (11 hours 21 minutes) which used 54% battery.
The relatively small battery has an advantage: you can charge it to full really fast. I suggest using a smart charger. It charges your Kindle with 1,4A until it reaches the 70%, after that it will gradually decrease the charging current. The whole charging takes only 50 minutes or so!
Hi I was wondering what smart charger you are using?
I have Oasis for close to an year now. I have been using for quite a while but even though it is my only eReader I usually switch between my S8+ and mine Oasis 2. I had the patience to mark all my first readings. With light at 8 which is usually ok for me or even off when I have light at the room, my Oasis 2 took all the way to 22 hours of reading. So 22 days with 1 hour reading which is usually what I read per day with the Oasis, at work I usually use my S8+ instead so I don’t have to carry both devices all the time and that is the advantage for me on the Whispersync!!
So for me, almost an entire month without having to charge Oasis is perfectly, perfectly fine!!
Really enjoying the eReader since I went from a simple Kindle 4 straight to the Oasis 2.
Had my kindle for a year. Have to charge it every 4 days, every day if it is indexing. Now I have to charge it every other day. Also my screen gets stuck on the screen saver and will not wake up unless I do a reboot. This is my 2nd oasis and it is worse than the first. Glad to see I am not the only one. What a waste od a lot of money. Amazon you duped us
I have all sorts of ereaders, but lately the New kobo clara is my favorite. The battery last much longer than all the others. So that’s a great ereader.
I have my oasis 2, fully charged at day 1. wifi off, brightness set to be 8 -9, then read the book around 1-2 hours per day, the batter only go down by less than 20% in 5 days. I’m quite satisfied with it.
Having not long purchased an Oasis 2 to upgrade an existing Kindle – I am very disappointed with the battery life on my new device. It seems that I am having to fully charge every couple of days. I read extensively so even with a fast charger this is inconvenient and constantly charging the battery will mean it will eventually burn out quicker too.
Seriously concerned that the claims made for this Kindle are obviously rubbish. Why would you buy a device with Wifi and bluetooth capabilities if it canes your battery. Lasting for week – complete fabrication and the results do not justify the costs for this newly improved product. Feel like asking for my money back.
