Kindle how long to charge

Subscriber Account active since. When in good working condition, a Kindle battery should provide more than 24 hours of use and will last in standby mode for weeks. If you fully charge your Kindle once or twice a week, you'll likely never have to deal with a drained battery. That said, there are times when your Kindle won't charge after a depleted battery. In most cases, you can bring it back to life with relative ease. Here's how.

If your Kindle is displaying a critical battery message or the drained battery icon, or if it's so dead its screen won't display anything at all, connect it to a power outlet and let it charge for at least half an hour before you test the device again. If the Kindle still won't charge, then you should first test the power cable in another device and try plugging something else into the outlet to make sure the issue isn't with either of those.

Try resetting the Kindle by holding down the power button for at least 20 seconds. Turn it back on and see if it charges normally. If it still won't take a charge, let it rest for about half an hour while connected to power, then try the reset again. For you. For those of us with regular access to a power outlet, feel free to enable or disable features at your discretion based on how you use your Kindle. Note: Instructions for following along with each tip are outlined for the Kindle Paperwhite, but they can easily be adapted for nearly every generation and variation of Kindle ebook readers.

But the Kindle occasionally suffers from a bug here or there that can put a hefty dent in your battery life. Previous battery-blasting bugs include issues with the Kindle indexing books and failing to sleep properly, for example.

But there are certain things that are rather difficult to make efficient. The Wi-Fi and 3G radios will, simply by their nature, drain battery much faster.

Unlike the very low power needed to change the display on the E Ink screen, it takes a decent chunk of power to search for and connect to nearby Wi-Fi nodes, and even more power to maintain a cellular connection to the faraway 3G cell towers.

Aside from keeping your Kindle up-to-date, this is hands down the best thing you can do for your battery life. The setting you use to read at night is most likely too bright or entirely unnecessary in full sunlight or even bright indoor lighting. You can access the backlight settings on the Kindle Paperwhite by tapping the top of the screen to bring up the on-screen navigation menu, and selecting the light bulb to increase or decrease the brightness.

Curiously, you can never turn the backlight completely off the lowest setting will still emit a very dim glow in a totally dark room but turning it to the lowest comfortable setting for your environment is ideal. E-Ink displays, even the high end ones, can sometimes have a problem with ghosting especially when reading books that have large amounts of charts or illustrations.

While the feature works great for eliminating ghosting, it also means that if your Kindle was good for, say, 10, page turns it will now only be good for, more or less, 5, page turns. If you rarely-to-never have a problem with page ghosting, you can extend your battery by turning off page refresh. You can always turn it on for those rare times you run into ghosting with an illustration-heavy book.

The Kindle Paperwhite has a little magnetic switch hidden just behind the lower right corner of the screen that allows the case to, courtesy of a very slender hidden magnet, trigger the switch and put the device to sleep.

As much as we love the case both we and several of our spouses have them there is a small argument to be made for considering a non-magnetic case. If you want your Kindle to have a long life, keep the device and enclosed battery at roughly room temperature. Lithium-ion batteries achieve maximum life cycles if they are not totally discharged frequently, not left to sit charging at percent for ages, and topped off before they fully deplete.

We need to recharge them so frequently, and nobody wants to be stuck with a dead device. Aim to take it off the charger either shortly after it hits percent charge or, even better, just before. Use the battery in this fashion and then, every once in awhile, allow it to run down to the point that the Kindle screen turns into the plug-it-in warning logo. Every time you add a book to your Kindle, the Kindle operating system will index it. This is the basis of the search function on the device and it happens for every book whether you add a novel from the Kindle Store, get a periodical emailed to your Kindle, or sideload a manual from your computer.

The indexing process is the most intense computational process the Kindle undergoes during regular operations, and the more books you add at once, the longer the process takes. Indexing one book can chew up a decent amount of time and battery life, but when you add tens or hundreds of books at once either by syncing a new or recently wiped Kindle to your account or via sideloading your index time skyrockets. The end result is the same, however: the indexing service gets stuck in a loop and it pounds the un-indexable book over and over again trying to churn through it.

Even if you restart your device, the indexing service will eventually get back to the same spot in the queue and get stuck trying to index the corrupt file. Tap the small arrow on the left side of the search box to expand the the results to display all the search categories e.

My Items, Kindle Store, Goodreads, and so on. Tap on that entry. If the indexing service is functioning normally, then it should return zero search results as the search query will not be found in any of the documents on the Kindle. If you just loaded a bunch of books on your Kindle or even just bought one or two you will see them listed here. If you select the entry for the not-yet-indexed items it will expand to list the books. Are the books you just loaded on the Kindle there?

Give it time to process. This is the state you see in the screenshot above; we loaded a ton of books on the Kindle to create a non-indexed book list we could screenshot. I just got one for Black Friday and noted the charge time. This it the proper way to quickly charge a lithium-ion battery.

I guess better to hedge their bets and overestimate the charge time than the other way around. I wonder, since you used the same charger on all of these, if charge time is about battery capacity. It should take longer to charge a higher capacity battery at the same charging rate, or at least it seems so to a non-expert like me. Most modern devices do this now. It helps with battery longevity.
