Here are ten rather obvious steps to maintain and extend your Kindle’s battery life.
- Turn off wi-fi and or 3G when not needed
- Turn down the back-light, if you have one
- Turn off automatic page refreshing
- Put your Kindle to sleep when not in use
- Ensure your Kindle firmware is up to date
- Keep your Kindle in moderate temperatures
- Lithium-ion polymer batteries like slow, regular charges
- Don’t fully discharge the battery as a matter of course, recharge at 30 – 60%
- Take the opportunity to add or sync your books while charging
- When the Kindle is nearly fully or fully charged, remove the charging cable
As a Kindle is essentially a Linux based computer, it’s a good idea, once in a while, to power off and or restart it. The IT two-step, “switch it off and on again” works for so many things, including Kindles, if they start misbehaving.
