Why jam the battery into one end of the thing instead of spreading it out flat like you see with other Kindles or tablets? Because doing so allows for a couple of awesome features. The edge of the Oasis that the battery cover connects to serves as a housing for the e-reader’s battery as such, it is wider and deeper than the rest of the device. The more abuse the Oasis’ leather battery cover takes, the better it looks. As such, a month into my using the Oasis, I’ve already had to charge it once. Amazon claims that between the Oasis’ two batteries, it’s possible to wring eight weeks of use out of the device, provided you keep your reading to 30 minutes per day and keep the screen lighting turned down to a reasonable level.

Covers cost extra on other Kindle models.) The cover starts charging the Oasis’ internal battery as soon as it’s magnetically mated to the e-reader’s asymmetrical chassis. To boost the Oasis’ run time, Amazon baked a second battery into its leather cover, which is included (you can choose from chestnut brown, black, or red. Where a Kindle Paperwhite can potentially go for months between charges, the Oasis’ internal battery can manage only about two weeks of use, depending on your reading habits. The Oasis’ light weight and superior backlighting come at a cost, however it has a significantly shorter battery life than its recent predecessors. The Oasis’ display backlighting is simply better. This isn’t to say that the Paperwhite is a horror to read on-I’ve been satisfied with mine for years. The Oasis employs 10 LEDs to ensure even backlighting across its display, beating out the patchier light the Paperwhite’s four LEDs produce. But with the backlights turned up, it’s a very different story. With the backlight turned off, I didn’t notice a difference between reading on my 2014 Paperwhite and the Oasis.

Like its chunkier cousins, the Oasis comes equipped with a six-inch, anti-glare, 300 ppi display.
