Kindle Dies Charges Then Dies Again

The Amazon Kindle has epic battery life, with the E Ink models lasting for weeks without recharging. But could you become more battery life by completely powering information technology down? Maybe.

The Amazon Kindle (excluding the Kindle Fire) and other E-Ink readers are ofttimes touted for their epic battery life. The new Kindle Paperwhite is being advertised with viii-week bombardment life on standby. How practice they achieve this? Role of the hush-hush is in how the E-Ink display works. Dissimilar LCD screens, which go blank when de-energized, an Due east-Ink screen doesn't need electricity to display an prototype continuously. It only uses power to create the image on the screen. E-Ink screens consist of millions of tiny microcapsules filled with pigmented fries. When an electric charge is applied to a microcapsule, certain pigmented fries rise to the surface, making them visible. Later on the image is configured, information technology's more or less permanent until it is "erased" by more than electric charges (sort of like a Magna Putter.) This is why an Amazon Kindle with Special Offers tin can brandish an ad on the screen when it is in sleep fashion while consuming little to no battery life.

With that beingness said, the Kindle tin can be turned completely off when yous are not using it. But should you? Amazon Kindle client service claims that it'due south not necessary to power downwardly the Kindle to maximize the battery life. Simply some Kindle owners disagree. Read on for the details of the debate.

Kindle Power Button Functions

The Power Button on the Kindle Paperwhite

The Kindle power button/switch has a few unlike functions. Though the location of the push button is different across the various models, the functions are largely the aforementioned:

• Kindle Sleep Mode – The Amazon Kindle can exist put to slumber by leaving it inactive for x minutes or rapidly pressing and releasing the power button. This will dim the backlight (if present) and brandish a screensaver or ad.
• Powering Off the Kindle – To completely power down the Kindle, press and agree the power button or ability switch for ten seconds until the screen goes bare. To plough information technology dorsum on, press the power push button again.
• Restarting the Kindle – If the Kindle is unresponsive, you can restart it by removing it from a ability source (if continued) and pressing and property the ability push button or switch for 20 seconds.

In sleep or standby mode, the Kindle uses a tiny amount, if any, of battery power. Amazon claims that battery life is "as long," whether in sleep mode or turned off. Theories exist that both back up and counter this assertion.

Kindle Paperwhite with Special Offers in Sleep Mode

The biggest business concern is with the WiFi/3G connectivity.  Some Kindle owners have claimed that their router however shows an active WiFi connection when the device is in slumber mode. However, in my tests, the Kindle promptly disappears from the wireless clients from my Airport Utility after putting information technology in slumber mode.

There is also some question whether the Kindle periodically checks for updates or new books while in sleep way. Co-ordinate to an Amazon Customer Service forum mail service from 2009:

Kindle'due south wireless bespeak uses low power while in sleep mode and so that your subscriptions can download overnight. If you are in a low coverage expanse, this could cause the device to use more battery power as it continually tries to maintain a signal. Unless you are subscribed to periodicals that you want to receive overnight, we recommend turning wireless off (Press the Bill of fare button and select "Turn Wireless Off" of the menu options) before leaving the device in sleep mode. This volition further conserve battery ability.

Kindles may have been redesigned to avoid this battery drain issue, only if in incertitude, you lot can e'er plow off wireless when you are not downloading content. In theory, this should guarantee that your Kindle uses the aforementioned amount of power in sleep mode equally it does when it is powered off (i.e., none.) You lot tin can turn off wireless by activating Plane Mode in the Settings Menu.

Kindle Paperwhite Airplane Mode

Those in the pro-sleep, anti-power off campsite likewise merits that it'southward non only unnecessary to power down the Kindle, but it's disadvantageous. Shutting down and starting up the Kindle likely requires more than power than simply resuming from the sleep state. Furthermore, powering down the Kindle with a long-press of the ability button is akin to a hard shutdown (east.g., pulling the plug on your computer) and can risk abuse or loss of information (eastward.g., notes, settings, final page read, etc.) Personally, I'm not sold on the risks of powering down—I think that the Kindle shutdown control is smarter than that and probably won't cause damage unless your Kindle is locked up for some other reason and requires a hard restart (xx-second power push press.)
