I received my new Kindle Fire HD 8.9 yesterday. I love it but I'm thinking there is something wrong with the battery, and if not then it's got a terrible battery life. I have a wall charger from a cell phone that I am using to charge it. It does take hours to charge. But once it it charged and I use it, it seems to drain way too fast. What is the average length of time people are getting on a full battery for the Fire hd? I mostly surf the web and play games.

Use this app to calibrate the battery to ensure best performance. You have to be charged to 60% and it takes 90 minutes to run but it is worth it.

Battery HD Pro

A little soon to tell but I am thinking 9 hours.

Etc I just checked Battery HD pro and it says I have 5 hours of web time left and the device has been on web or video for 5 hours so 10 hours.

What do you mean by way too fast?? Playing games will drain it pretty quickly as well as playing movies. I don't have a Fire but my 10" tablet gets about 6-8 hours of battery life playing games and watching movies.

Thanks Nospin. I do have that app, I read that on another board. I'm waiting for it to charge. I'm using a cell phone charger that fits it, and it's taking a really long time. I hate to buy the rapid charger until I know it's going to hold a charge for longer than a couple of hours. If that's all I'm going to get it's going back.

Sorry Jeff, I should have specified. It's only holding a full charge for maybe 2 hours. I'm going to test it today when it's done charging.

I actually used this last night to charge

That looks pretty handy.

That is what I love about the charger for my Toshiba Thrive. I can go from a fully drained battery to about 85% charged in an hour. Fully charged in an hour and a half.

I have another question about charging. My daughter has an itouch, when it's completely dead if it's plugged into a charger and is charged enough to turn turn it back on, it will not drain any battery as long as it's plugged in. (Is that ok to do for a battery?) Like my laptop as well, and I assume the ipads would do the same as the itouch. But the Kindle Fire consintues to drain even after it's plugged into a charger. Also annoying that it doesn't give you any warning, it just shuts off, but luckily there are apps for that.

All chargers are not created equal. Get one that provides enough power. Apparently the one you're using isn't doing the job.

ETC: typo

Are you saying if I get a better charger (like the one Amazon sells for the rapid charging) that I would be able to plug it in and still use it while it is charging? At this point I am waiting to see if the battery draining issue can be resolved by by the Battery Pro HD app. if not, I'm returning it.

Too many variables to predict.
It depends what you are doing. Light web surfing does not drain t h e battery like watching videos.

Unless there's some as-yet-undetermined defect with the device itself, another charger should take care it. I'd venture to guess that tech support would have you start the troubleshooting process by first ruling out things such as the charger. But it's your option to return it.

If your charger's specification is less than 9W, 1.8A (required for Kindle Fire HD 8.9), the charger is too weak. Example: My iPhone uses a 5W, 1A adapter. It's too weak to charge any tablet.

I'm getting about ten hours of mixed use (reading, video, surfing, etc.) on my HD 8.9, but I don't let it run down all the way. Takes about five hours to charge with the Amazon quickfast charger.

With a 1A charger, you can expect it to take eight to ten hours to charge. With a 700mA USB outlet from a computer, it will take about fifteen hours.

I've been trying to catch up on all of the past episodes of Sons of Anarchy, and watching 4 shows@ 45 minutes each, takes my battery down to 1/2 charge. I really need to stop watching, I'm burning up every evening on this darn show....obsessed!

I am using the charger that came with my Kindle keyboard to charge my Fire. I don't know the specifications of this charger. Does anyone know if it is fine for the 8.9 Fire?

Posted on Nov 19, 2012 9:01:14 PM PST
It will work, but probably take longer to charge.

I just bought the power charger. Since the Fire will be used for more things that drain battery life than my regular kindle, it seemed like a smarter bet to get this

I talked to support, they had me do a factory reset. That definitely did increase the time, and I added all the same stuff back on it. I even keep the wifi on all the time now. It's more like 6 hours playing games now and when it's not being used it lasts at least 8-10 hours. That's much better. Support said that usually that helps. So if anyone has battery issues try the factory reset. To factory reset your Kindle Fire:
1. Swipe down from the top of the screen and tap "More".
2. Tap Device, and then tap Reset to Factory Defaults.

Another thing you want to watch is if any of the apps are running in the background that you don't know about. That can eat away the battery as well, I was havign that problem on my cell phone and downloaded a app killer app that will close running apps not in use every 10 mins or so.

When you did a factory reset it clearead out all the apps you had downloaded so if that was the problem it was fixed with the reset.

Something you can try is to allow it to discharge to 15% then recharge it fully. That's really not necessary on newer batteries, but it can't hurt and might help reset any battery charge sensing routines on the device.

I can't even figure out how to close the apps other than go back to the homepage. But I guess that doesn't close them completely? I'm still learning.

Same here, please help. Got it yesterday and my laptop sux at charging it, so after hours of using electricity, I unplugged it before going to bed. Fire hd was almost dead by the time I got back to it. I have been charging from a plug for over 4 hours and am only to 47%. I dont know if I have things running in the backround by hitting home instead of back which is how it is on my phone, but at least my phone tells me. I love this so much, but if its going to take hours to charge then I will have to return it :(

Look at it like this. It has a very high capacity battery. Much greater than on your cell phone. The adapter can only put out so many amps.

If you turn on a water faucet (the charger amps) at a steady stream, it will take much longer to fill a large pail (battery) than a smaller pail. Its the same thing with the batteries. Using the USB charger is like using a water trickle instead of a steady stream.
