Is It OK To Keep The Kindle Fire HD Plugged In After 100% Charge?

I just got a Kindle Fire HD 7" and I read it's better to charge it above 25% instead of waiting for it to go lower. Once it is at 100%, should I keep it plugged in with the fast charger? Or should I plug it in, then immediately unplug it at 100%, then plug it back in at 25% again, over and over again?

You don't need to immediately unplug it at 100% - it won't overcharge if left plugged. Also, as you've read, it is best to charge before the battery gets too low, but you don't necessarily have to wait until it gets to 25%. You can charge at any point when it's convenient to do so.

I've read so many conflicting posts about this that I don't know if it's better to let it drain down to 50%, 25%, etc. or if it doesn't matter what percentage as long as you don't let it go too low. Everything I've read seems to agree with not letting it go too low.

If I'm near an outlet I'll plug in even if I'm at 100%.

I keep my Kindle Fire HD 7" plugged in and have had no problem. What I do like about the new 7" HD Kindle Fire is that it keeps a charge a lot longer than the first generation. ENJOY!

Hi, thanks for your inputs!

I read that Lithium polymer batteries will lose their "lifespan" faster if you let it fully drain/discharge often. Apparently, this should happen intentionally once a month, and it's better to keep a charge in them (at least 25%).

Each type of battery has different properties, based on what they're made of, and the Kindle Fire HD uses a Lithium polymer (Li).

The things I find consistent for better daily battery efficiency are:

1. Adjust the backlight to something dimmer.
2. Turn off the wi-fi when not needed, even when in sleep mode.
3. If you are certain about which ones, turn off background processes (unused apps/games/widgets) that are "cached background processes".

To keep your long-term battery "lifespan" lasting longer:

1. Discharge it fully only once a month, then re-charge it 100%.
2. Maintain a battery charge at 25% or higher.

Typically, an electronic device that has a rechargeable battery, should stop charging when the battery is at 100%. If it doesn't, it will greatly reduce the ability to recharge in the longrun, which would be considered damage. I have read people have been having strange battery problems, but I don't know if they're using the official Amazon Kindle Fire HD fast charger.

If it is plugged in, it is constantly recharging, for example, 99.9% back up to 100%. It's the fast charger I'm using, which is high power.... So it's not actually a stop charge, switching to plugged-in mode, where the battery is then bypassed. It might not be better than charging it over and over again from something like 50% or 25% because it is a high power recharge? It really depends on how the battery was made, and I can't find information on the internet about it.

Hi Yaa812 and MariaA37,

How long have you had your Kindle Fire HD 7"?
