A:Answer The length of battery time does vary according to how bright you have your screen and whether or not you are in airplane mode. When I am away from home, I turn on airplane mode so the kindle isn't constantly searching for an internet connection and have found I can get between five and six hours of reading time. Also, If you use the Kindle covers offered by Amazon, the battery tends to run down faster ( I think it's because when you close the cover, it turns off the kindle but I think it just puts it into standby mode as the kindle tuns on automatically when you open it again)
