My Kindle Fire's battery lasts 7 days. I alternate reading on it with my Kindle 3rd Generation Keyboard whose battery lasts 30 days.
Most of my use for the Kindle Fire is as a battery operated portable radio using the app, Tune In, and a Sony speaker. Its the best battery operated portable radio I've ever owned. I also use it to play my MP3 songs from time to time. I use Alutrek WiFi radios as permanent radios around the house and the Kindle Fire as my portable radio. I leave WiFi on all the time on both since I am constantly syncing between them. Shutting down for the night closes all apps including WiFi. That way I am not bothered going separately to the WiFi icon. I leave the Fire in Sleep Mode during the day. Does anyone have any recommendations for Android Battery Apps specifically constructed for the Kindle Fire? Others have telephone timers built in for battery use which are not applicable to the Fire.

Thanks for the replies everyone. Most of you seem to be getting longer battery life compared to me. I'd say I get 5 hours tops a day, there has been times that it has even seemed less. I mainly use mine for reading and surfing the web, but sometimes I also play games on it.

Hmm.. I don't have very many really. Here's what I have:
Adobe Reader Angry Birds Angry Birds Seasons Angry Birds Rio Bubble Burster Doodle Jumo Fruit Ninja Free Jewels Ebay Jelly Defense Paper Toss Tapatalk Random Mahjong The Weather Channel And then the ones that came loaded. The only thing I can figure is the couple of times I watched youtube videos it really sapped the battery. I'll see how it goes this week. Today it seemed to last longer. |

An interesting, not-too-technical read on best use practices for Lithium-Ion batteries with links to more detailed information:

Key battery guidelines
Quote:
"LIBs have short lives (in comparison to NiCa batteries, etc). You should expect to buy a new battery in 2-3 years after being manufactured. It is caused by internal oxidation and there's nothing you can do to stop or prevent that. Same goes to WiFi connection - although it's on, if there is no data flowing through it, it uses almost no energy" Thus, in 3 years at the most we will be buying the Kindle Fire of that year. Also, leaving WiFi on all the time uses almost zero energy if we are not receiving or sending data. That link also recommends a full TWELVE HOUR charge when first receiving one's LIB (Fire). Maybe those, who are getting low battery times until depeletion, should try an overnight charge to perk up their meters. Last edited by sirmaru; 12-07-2011 at 03:07 PM. |

The main takeaway is to do a full cycle charge every once in a while. Don't just take it down to 70% and bump it back to 100% all the time. Also, the apparent quick draining may be a misreading of the battery status by the Fire's innards rather than actual short battery life. Quote:

I never charged my battery for 12 hours either when I first got it. It states at the link frankz posted that's a good idea. (Thanks for that link, Frank) Maybe that would help. The most I have done is overnight, maybe 8-9 hours or so. |

Since installing Badass Battery Monitor, I'm getting a result that the Kindle System uses 47% of my battery consumption while the screen uses 24.42% and WiFi uses 22.46%. Its worth it to me to leave WiFi on since I sync a lot between my Fire and 3rd Gen Kbd.
My eReading (Amazon Kindle) only uses 0.18% while the Launcher and Kernel use 1.37% each. Badass Battery Manager uses 1.32% and the AppStore uses 1.26%. All other Apps uses less than 1%. Thus, most of the battery usage is done by Kindle services just opening the Kindle Fire. The Kindle System, Screen, Launcher, Kernel and AppStore combined use 75.42% of my battery consumption. If I add in WiFi, I'm up to 97.88%. Reading eBooks and playing chess on the Kindle Fire use negligible amounts of juice. Kindle services excluding the Screen but including WiFi are active in sleep mode. Shutting down at night ends all processes for that period. Badass Battery Monitor will need several charge cycles to produce an average battery life which will still be influenced by the initial short battery cycle after installation to the first charge. At the present time my current battery usage is 6% with 94% remaining and reflects 52 minutes of use with a projected life to the next charge of 11 hours. That is way OVER the original estimates of just 7 hours of battery usage between recharges. However, the Kindle Fire gives a low battery usage signal at 15%. That means I probably have a full 12 hours of usage available but will have to recharge after every 10 hours of use to comply with the battery usage signal. Active games probably shorten that life. Chess, however, is NOT an active game and uses negligible juice. I recommend that everyone install Badass Battery Monitor now at version 1.7 and report back here their own battery usage statistics. If games cause unusual drains, this Monitor will detect them and their usage. Last edited by sirmaru; 12-09-2011 at 09:48 AM. |

With badass battery monitor it says 2 apps are using most of my battery. (Kindle System and Amazon Kindle) I noticed that when I shut down my kindle the game apps that were running before are now gone so maybe I didn't shut them down properly and they were running the background. I'm thinking that is what happened because since then my battery life has been much better. |

Going to install the BBattery Monitor and check what vevo is doing while idling. Very curious after what Blossom experienced!
Will report back in a few days once I get a decent average. Thanks for everyone else's data! Hugs, Ratkity |
