All-new kindle oasis battery review năm 2024

When I reviewed the Kindle Oasis 3 in early August, I talked about how I wanted to do an in-depth battery life test.

The Kindle Oasis has gotten a reputation for having poor battery life. Read the reviews at Amazon and you’ll find plenty of complaints.

But poor battery life can be attributed to the way Kindles index content initially, especially when adding a bunch of content to a new Kindle all at once, so I wanted to do some tests to see what the battery life is really like.

I had visions of doing a long detailed test using a bunch of different variables, but after six weeks of barely scratching the surface, it’s clear now that the idea of doing a detailed battery life test is just too time-consuming an impractical.

For instance, I really wanted to test Amazon’s battery life claim of 6 weeks based on reading 30 minutes per day with the frontlight set at 13, but when it comes right down to it having to stick to such strict rules takes all the fun out of reading. Having to use to the light at 13 when it’s too bright at night and having to read 30 minutes only (not a minute more or less), is a real hassle.

But I did learn a lot over the past 6 weeks testing the Kindle Oasis’s battery.

The main takeaway, I was really surprised by how much longer the battery lasts by simply turning off the frontlight. The lights drain the battery a lot more than I had previously thought.

Based on my tests, the battery will last upwards of 40 hours per charge when doing everything possible to maximize battery life—turning off the frontlight, using airplane mode, turning off the touchscreen, using a small font size for less screen refreshes, etc.

It should be noted that this estimate applies to reading only and not navigating around and using a bunch of different features.

But still, that’s way longer than I was expecting, and it’s a fairly conservative estimate. The battery meter consistently goes down by 2% per hour under those circumstances, occasionally 3% so the actual number is somewhere between. On a number of occasions I read for an hour and fifteen minutes with only 2% battery drain.

On the flip side of the equation, it’s also possible to completely drain the battery in under 9 hours total, possibly even 7 or 8 hours if the circumstances are just right.

It’s pretty easy to drain the battery that fast too. All you have to do is have the frontlight maxed out, or even if you’re just listening to an audiobook.

So I can see why people would say battery life is terrible on the Kindle Oasis. If you just simply have the frontlight cranked up, battery life is going to be awful. But if you have it turned off or down low you can easily triple or quadruple battery life.

In short, battery life greatly depends on how you use the Kindle Oasis. It can be surprisingly good or surprisingly bad. The number one thing you can do to improve battery life is to turn off the frontlight, or at least turn it down to the lowest tolerable level.

The All-New Kindle Oasis is well-built and a pleasure to read on. It’s well-worth the expense for serious readers.

The very name of Amazon’s “All-new Kindle Oasis” would seem to herald a radical overhaul. Thankfully, the changes to Amazon’s top-shelf e-reader are far less dramatic. Beyond the introduction of a new color-adjustable front light that can warm or cool the screen’s illumination, the All-new Kindle Oasis remains strikingly similar to its predecessor. And that’s good news. It’s still the best e-reading experience you can buy.

The all-new Kindle Oasis no impulse purchase, though. The base level device, which includes 8GB of storage and Wi-Fi connectivity, starts at $250 if you’re willing to tolerate “special offers”—i.e. advertisements—displayed on your lock screen. Prices rise steadily from there. That same unit is available without ads for $270. A 32GB model with Wi-Fi runs $280 with special offers and $300 without. Finally, a 32GB model that adds free cellular connectivity and includes special offers costs $350. Three months of Kindle Unlimited are included for free with all of these; you’ll be charged $10 a month if you choose to keep it thereafter.

All-new Kindle Oasis specs, features, price

The All-new Kindle Oasis is a luxury e-reader, which shows in the generous feature list:

Storage: 8GB/32GB

Display: 7-inch (diagonal width) with E Ink Carta and 25 LED front lights, 300 ppi, 16-level grayscale

Dimensions: 6.3 x 5.6 x 0.13-0.33 inches

Weight: 6.6 ounces

Connectivity: Bluetooth, Wi-Fi, and 4G LTE where available in the US

Battery life: Up to six weeks on a single charge

The All-new Kindle Oasis keeps much of the look and functionality of its predecessor.

Design

The 2017 Kindle Oasis nailed the luxury feel of a premium product, so it’s no surprise that the All-new Kindle leaves most of its design elements intact. The dimensions are identical, and the weight nearly so. Amazon removed the rear-housing magnets that attached the previous model’s cases, dropping the weight from 6.8 to 6.6 ounces. The aluminum backplate (available in Graphite or Champagne Gold), glossy black bezel, and glare-free glass are all still here.

Like the previous Oasis, this new version has an IPX8 rating, meaning it can withstand submersion in up to two meters of water for an hour at a time. It’s hard to imagine a reading scenario that would require that kind of aquatic abuse, but it should put at ease users who like to read in the bathtub or on the beach.

The new lighting feature adds a “warmth” slider under the brightness slider in the settings menu. By dragging a finger left to right you can adjust the color tone incrementally from cool to warm to better suit day or night reading. You can also schedule the warmth level to change automatically with sunrise and sunset, a feature that will be familiar to anyone who has used Apple’s Night Shift to control the color of their Mac’s display.

The new color-adjustable front light lets you cool or warm the Oasis’ lighting.

The other most notable change is that with the magnets gone, the Oasis now snaps into its cover like other Kindles. So, be prepared to tack the cost of a new cover onto the total purchase price. I was provided the Charcoal Black water-safe fabric cover, available for $40 on Amazon and also offered in Punch Red and Marine Blue. A Kindle Oasis Premium Leather cover is available for $65, and a Kindle Oasis Leather cover is $50 in either Black or Merlot.

The All-new Kindle Oasis comes in 8GB and 32GB models. Which one is best for you depends largely on whether your reading habits lean more toward e-books or storage-sucking audiobooks. The latter will also deplete the Oasis’ battery faster, which Amazon says can last up to six weeks on a single charge under the most austere circumstances: reading only a half-hour per day with wireless and Bluetooth turned off and the light setting at 13 (out of 24). Your mileage will vary.

Usage

While Amazon has diligently made regular updates to its Kindle devices, the evolution of the e-reader’s software has been much slower. That means if you’ve owned any Kindle in the last few years you won’t have any particular problem using the new Oasis right out of the box. Devices settings, Goodreads, and the book store are all parked where you’d expect them, in the top toolbar along with the Home and Back buttons.

The waterproof Oasis can be safely read in the bathtub and will even survive if you drop it in the water.

Text on the 300ppi display of the All-new Kindle Oasis is noticeably crisper than on either my 8th-generation or All-new Kindle, both of which top out at 167 ppi. It’s the closest I’ve seen an e-reader come to the experience of reading a printed text on paper. Of course, you can customize the font, type size, line spacing, page margins, and more to your liking.

Now that even the entry-level Kindle includes front lighting, the feature doesn’t seem so novel anymore, but it’s still welcome inclusion for nocturnal readers. As with the warmth lighting, you can adjust it manually in the settings menu. I found it easier, though, to leave it to the device’s built-in light sensor to adjust it automatically based on the room’s ambient light. I usually found its level selection just right.

Reading on the Oasis remains a luxurious affair. I’ve always found it a little awkward to hold the basic Kindle or Kindle Paperwhite. Holding with thumbs on their bezels inevitably results in errant page swipes, so I typically resort to cupping those devices by the edges. That solves the page-turning issue but makes my hands fatigue faster. The Oasis’ battery bump makes the perfect handle for cradling the device comfortably in one hand. From there you can easily manage the page-turn buttons with your thumb, which I find much more precise than finger-swiping the touchscreen. Its feather-light weight allowed me to read for hours without any physical discomfort.

I’m not bathtub reader, but in the interest of stress-testing the Oasis’ waterproof feature I submerged it in a bowl of water. Other than a few page turns, no doubt from the pressure of the water on the touchscreen, the device showed no signs of malfunctioning. Again, odds are the Oasis won’t be subjected to that level of water exposure during real-world reading, but it can handle a few drops of rain or a splash in the pool.

Verdict

The All-new Oasis remains the ultimate Kindle. Its level of luxury is unparalleled in the e-reader category, and certainly no other reading device can match the range of content a Kindle can provide. Understandably, even the base-level Oasis won’t fit within everyone’s budget. For those folks, the scaled-down Kindle Paperwhite or All-new Kindle will let you take advantage of all the digital content Amazon has to offer at a fraction of the price.

How long should a Kindle Oasis battery last?

Amazon estimates that the battery in the Kindle Oasis (2019) will last you for six weeks, but that's with a few caveats: to achieve that figure you'll need to limit your reading to half an hour a day, keep Bluetooth turned off, and the brightness setting on 13, which is roughly half brightness.

Why does my Kindle Oasis battery drain so fast?

If your Kindle is set to refresh too frequently, it can drain the battery faster. You can adjust the page refresh rate in the settings menu. Choosing a longer interval between page refreshes can help boost battery life.
