16 hour battery life for real? Which one is accurate?
524355
The A2 has a slightly bigger battery. 5600mAh instead of 4800mAh. Same number of cells. Does it really last 16 hours? Couldn't tell you for sure, but it does last a good long time. This reviewer found the A1 lasted 9.5 hours with Vista on balanced power profile, wireless enabled, and screen at 70% brightness. Asus says the 12 hour figure is with wireless off, which would make sense given that test result. Here's a discussion thread on the various UL-30 models and their claimed battery life numbers: http://forum.notebookreview.com/showthread.php?t=426274 Battery life is notoriously difficult to test and methodology varies widely from company to company. You're best off finding a reviewer, reading about their test methodology, and looking at their results for the laptops you're interested in.

My battery charge has reliably lasted 3 to 4 hours depending on what I'm doing on my computer.

How many watt hours for the battery ? One site (liliputing) says 47 WHr (which will definitely not last 7.5 hours). However a user on that site that his is 63 WHr, which is much more likely to last the stated 7.5 hours.Thanks for any answer, ASUS.

I've never had mine die on me but I've taken it for a six hour trip and it had about 25% battery power afterwards so I'd guess maybe about eight hours in total.

I really haven't tested the battery life per say.....but I have had it on for more than two hours with the battery still holding charge. Hope this helps.

depends on what programs you will be running...I can get 6hours out of this battery.

I have had mine for several months and I still get 3+ hours on a charge.. Awesome battery for the money IMO.

I get less than 2 hours of use on a full charge (mainly using for internet browsing, email, and playing mp3). The battery also drains when it's not on. I have the 16 GB linux version with advanced desktop enabled. This seems to be common. I think most manufacturers exaggerate battery life a lot, if it's not a flat-out lie. So 2 hours or less of use unplugged with this device is probably the norm, if the manufacturer is saying 3 to 4 hours. My experience with most rechargeable mobile devices is that normal real world use will not get anywhere near what manufacturers state for battery life.

I'm not sure of the actual battery life but I use it during hunting for tracking and with a full charge it lasts in full power a good 20-30 mins before bumping down to the next level. I absolutely love this product and definitely worth it.

I'm just testing that myself. So far I have three hours on a full charge at full strenght

My $15 version is sealed also. Even with the display on continuously, the estimated battery life is 4 to 5 years. I plan to simply buy a new, improved version when that happens. There may be a more expensive version with a replaceable battery.

I just used mine for 6 straight hours, and 2 hours the day before, still going strong. I would estimate 10 hours full charge to dead.

it doesnt matter 8gb or 16gb they have the same battery life, its battery life is like 4-7 hours depending on how you use it... Its battery life isnt even close to what apple claim it to be.

I would say the 6 hour figure is accurate. I used recently in Europe at 3G and experienced 6 hours.

I've been using both batteries consistently since I've bought them. The readout on the screen will initially say over 9 hours but I record in 1080p and get 26 actual seconds for every minute it says I have. Both batteries in real world testing, about 4 hours 30 minutes of actual use.

I would say I get a good 10-15 hours of runtime on a single charge, and standby time is also pretty good, charges up pretty fast also!

Hey bro...i just got mine yesterday and I've used it for so far 3 to 4 hours...and it works well...I'll make sure I put it up on exactly how many hours the batteries will last...
