How does it affect battery life compared to using the screen?

I haven't noticed any adverse affect to the life of the battery. I love the view finder especially in the bright sunlight when there is glare off of the screen.

Have had the viewfinder for almost a year, but couldn't tell you if it drains the battery any more than not using it. I do know I couldn't use the camera without it in bright sunlight. I also carry an extra battery. The viewfinder is big and bright and works really well,very pleased I bought it.

I can't distinguish a decrease in battery power, but I have it so that it's in power saver mode. The eyepiece comes on when my eye is positioned in the viewfinder, otherwise it's not on.

I see no difference in the battery life when using the viewfinder. I wouldn't be without the viewfinder. Love, love it!

I use it for everything except movie watching (I use a chromecast for that). Battery life is actually pretty good. It does not handle super graphics intense games, but It can run Sims 3 for example on the fastest speed with pretty good ease. More graphics intense games would probably struggle a bit or need to have settings lowered. I have been able to play games for at least two hours (maybe three) without the battery going dead. Web browsing and word processing could last a much greater amount of time.

The screen resolution is great. A full battery usually last me around 8 hours.

You lost 4% battery in 20 minutes? That's about 12% an hour putting you around 8.5 hours. Yup, that's about right. It doesn't matter what programs you have "running" in the background. The iPad OS works differently from your Windows OS, the stuff is there, but not running. It will not drain your battery any faster. The biggest factor is going to be how bright your screen is. I usually have mine around 40-50%, plenty bright for indoor use and my battery lasts 9+ hours. Also if you're reading a book turning off wifi will help a bit. 9 hours of continuous use is PHENOMENAL for a device like this. I constantly use my iPad throughout the day and I have never drained the battery all the way. My Galaxy Nexus on the other hand is abysmal; after about and hour of talking and a few texts the battery is at 60% it's horrendous. When I got my first smart phone (a Droid X) I was constantly obsessing over the battery life and if it was dying too quickly or if it wasn't going to sleep properly. I would look in the app market for apps that would help battery, spent hours researching charging methods etc. and it really took a lot of the enjoyment away from me when using the device. Then I learned to just not worry about it, if it needs charged, charge it. Bottom line, so long as you charged it each night before bed, you should never get even close to fully draining it in one day. Unless you're using it 9+ hours a day to which I would say you have bigger concerns then just your tablets battery life.

Your question cannot be answered accurately. There are too many individual variables that can effect battery life. I can say that my battery fit perfect, charges quick and keeps a decent couple of days charge and was a decent price. Hope this helps out.

Yes and no. Kill all apps and turn your screen off. Then it will keep up. With screen on it draws too much juice.

Using minium programs with dim screen settings I have gotten close to six to eight hours usually. While gaming heavily usually with bright screens closer to four.A big plus though is that it recharges very quickly.

As far as I know, it hasn't affected battery life. This isn't a battery, just an accessory. I have had 3 phones (2 probably refurbished) completely stop charging while under warranty. Not sure if using this had anything to do with it.

Unless you're using the device full time and you have the display at max brightness the battery lasts for several days. On standby mine has gone 2 1/2 weeks before going to below 10% power. Hope this helps.

Battery life with this attached is not good, less than one hour if the screen remains on. Even turning the screen on and off significantly reduces battery life as compared to the camera without the screen. Without the screen, in mild temperatures, I can leave the camera on for 2-5 hours taking pictures and video intermittently. With the screen attached and on, the battery would last less than an hour. The screen can be powered off separately from the camera but I still found a major reduction in battery life just turning the screen on and off for intermittent shots. Bottom line, there is a huge tradeoff to having this attached in terms of battery life. It is a a legit LCD touch screen and even comes with a waterproof touch screen cover that allows you to submerge the camera to a shallow depth yet use the touchscreen (when not underwater). It also comes with the solid back door and vented backdoor as well.

No. The screen only turns on when you look at it. You don't need to have the screen on if you aren't looking at it, so this saves battery. Battery will last 2 days no problem. I charge more at night while I'm sleeping, same time I am charging my phone.

I just got the 16GB for Christmas. After reading all the battery posts, the first thing I did was charge it fully, then play it until the battery died. I got 20+ hours. I think a lot has to do with how often the screen is "lit". If you're constantly shuffling through, picking songs, adjusting volume etc. i think one would get less life than just playing it like I did (the screen was black most of the time since I wasn't adjusting anything). And of course, i would expect video or games to kill the battery even quicker. That would be a good test, play a video straight through and see the life. I don't have any videos loaded, so I can't really test that. I just got the 16GB for Christmas.

The battery life is good for anything I have been using it for. I am not sure what the difference is between the two sorry wish I could help more.

I don't notice a difference as far as battery life is concerned. They work great! One thing that I did notice, the battery is hard to remove from the charging case but I have only charged the batteries a couple of times. There is a video that shows u how to remove them and l will look at that again someday.....Not a big deal.

No it doesn't affect it at all. In fact, it makes the screen smoother and it won't get finger print smudges as easily.

As with anything that covers your screen, it does impact the quality a little. It's not much of a impact, i noticed more glare when holding the phone at an angle more than anything.

No real noticeable difference, hovering over the screen with the stylus still produces the same small circle, pressing the button on the stylus still makes the shortcut menu appear and the touches/long presses feel the same. Only difference is that you're pressing against a glass surface versus a screen protector so it's hard vs soft.
