How do I cancel Kindle Unlimited before it starts charging me?
Decide before you set the device up whether you intend to keep it, and if you do not, put the cancellation date in a calendar the day the Kindle arrives rather than discovering the charge on a statement months later. Cancel through your Amazon account's membership settings; in general a cancellation takes effect at the end of the current period, so you keep access for the rest of the trial. Two things are worth knowing about the subscription itself: it is not access to everything in the Kindle store, since many popular and recent titles are not included, and it is a convenience layered on top of the device rather than something the Kindle needs in order to work.
My battery drains much faster than six weeks. Why?
Almost always the front light or wireless being left on. Both are large draws compared with page turns on an E Ink device, since the screen itself needs no power once a page is displayed. Turn the light down from maximum, and switch wireless off between downloads rather than leaving it connected all the time, and battery life improves considerably. That is why battery life can seem amazing on one Kindle and terrible on another: settings make a very large difference.
Can I take it to the beach or read in the bath?
Not safely. Amazon does not describe this model as water resistant, and the pricier Paperwhite is the one to buy if you read by water, in the bath or around messy kids. A single accidental drop in water can end the device. If reading near water is a regular habit, pay for a water-resistant model instead.
It's glitching or freezing. What should I do?
Restart it first; on any Kindle this resolves most glitches. Hold the power button until the restart option appears, or until it powers off and back on if no menu appears. Keeping the software updated prevents most recurring problems, since Amazon fixes known bugs through updates. If taps occasionally skip pages or fail to reach Home, a lighter, squarer tap usually helps.
Should I buy this base model or pay more for the Paperwhite?
If you read indoors, in bed or on the move and want the lightest possible device, this model is arguably the better buy and the money saved is real. A reader who does not read near water and reads in plain black and white may not need water resistance or the Paperwhite's extra lighting options at all. If you read in the bath or by the pool, the Paperwhite is the safer choice. Compare both during a sales event, since the gap between them often narrows then.
Is 16GB enough storage?
For books, yes. Amazon says 16 GB holds thousands of books, magazines and comics, and storage is essentially a non-issue for reading text. It only starts to matter if you want to keep a very large collection of heavier files such as comics on the device. Books bought through your account stay in your library even when removed from the device, so you can always clear space and download them again later.
