Samsung Galaxy Tab Pro 8.4 and 10.1 Review
by Jarred Walton on March 22, 2014 9:30 PM ESTBattery Life
For battery life testing, we run the displays at 200 nits and test Internet surfing and H.264 720p video playback. In some cases the tablet OEMs have features built into the software that lock display brightness to a low (minimum) setting when battery life is less than 10%. The Galaxy Pro offerings appear to do this, though you can override the behavior in the power options. In real-world use, you can expect perhaps slightly better Internet battery life (as it's unlikely you'll be refreshing pages every 20 seconds) while the video playback results are exactly what you would do if watching a movie.
The Nexus 7 wins the WiFi testing result while the iPad Air and Mini Retina take the top two spots for the video playback (and silver and bronze in the Internet testing). It’s interesting that the two Galaxy Pro tablets are so close on the Internet results but the 10.1 does substantially better on the video playback. Either way, both tablets are at least capable of reaching their “up to 9/10 hours” advertised battery life, with perhaps a bit more if you’re willing to turn down the display brightness or shut off WiFi.
There are better tablets if you want as much battery life as possible, but given the ready availability of portable chargers and such I'm not sure it's all that critical. Gaming battery life is lower than the above results, of course, so plan on more like four to six hours of gaming (depending on the game) before needing to plug in.
Storage Performance
Having used several older Android tablets, the drop in storage performance over time can be extremely painful. With Android 4.3 and 4.4 now supporting TRIM, hopefully things will stay running a bit more smoothly over a long period of time. As it stands, we don’t have all that many results for our Android storage benchmarks (and no cross-platform test for iOS yet), but the Samsung eMMC looks to be better than most of what we’ve tested. The random write speeds in particular are nearly twice as fast as that of the Nexus 7, and we’re at least consistently beating typical hard drive performance with >1MBps random I/O. Hopefully we’ll see even faster NAND/controller solutions upcoming tablets.

Jarred - That is the same issue with anyone who has bought into any ecosystem. Its a valid concern but not one specific to the Kindle. More valid would be that their app selection is significantly smaller, and versions are often out of date (a problem shared by the WP ecosystem). But concerns about switching apply to everyone in every ecosystem equally and are not platform specific. I'd argue that its less of an issue for Android users going to Kindle (and vice versa) since most of the apps can at least be sideloaded or installed via third party marketplace.zepi - Wednesday, March 26, 2014 - link
$100 would be the price of the software. Not the worth of it. Some software can be free, yet insanely valuable. Some companies would easily pay hundred dollars per each linux-installation if they had no other choice, but get them free, because they are worth way more than $100 to their business.Value you get from software is unique to everyone of us and fluctuates over time and is not constant. Value of a flashlight app might be high when you are strolling on a dark beach and forgot your flashlight home (you would easily pay a dollar if no free versions existed), but during a bright summer day on a baseball court you wouldn't pay a penny for such app.
Are there a lot of apps that are actually worth a lot to you and you couldn't get to an amazon device? What is the total cost of reacquiring them?
In the end, we are not rational customers. We count things "we lose" in terms of actual dollars even if in practise none of it would matter at all just because we think it's ours. Psychological research suggest that people hate giving up more than getting new stuff. http://en.wikipedia.org/wiki/Endowment_effect

Go look at the new study showing that Apple apps crash 2+ times more than android apps even though apple's store is curated and Google's is a "free for all."Mondozai - Sunday, March 23, 2014 - link
Lighter, high quality displays, top specs and cheaper.The drawback of the Android store is an issue but on basically every other metric they are better.
Also, Reflex, even if Amazon is not as cavalier about privacy as Google, people are right that you are a bit too trusting. Their TOS isnt necessairly 100% honest/transparent.
Reflex - Sunday, March 23, 2014 - link
While it is true that Amazon could be lying, as could any company's TOS and privacy policy, that would be legally actionable and on that basis you simply cannot trust anyone anywhere and should just unplug from the internet. Companies can and are sued for violating TOS/Privacy Policies, as LinkedIn recently found out and as Facebook is finding out in Europe.Yes, Amazon could be lying to us all. But that is no different than anyone else, and if you find out that they are, its time to retain an attorney and start a class action.

Wow...I am not Google fan, but you are extremely ignorant if you think Amazon is leaving tens of millions of dollars a year on the table by not selling advertisers the habits of Kindle users. How do you think they make more of their money on Kindle? It is not a huge profit margin device. And all those free apps? Howe do you think those are paid for? The kindness of strangers?Amazon's MAIN business model this to sell things to you. That doesn't mean they don't have a second business model with the Kindle of selling YOU to advertisers. They do.

More cheap derivative junk from Samsung that will be in the bargain bin in a month or so.JarredWalton - Sunday, March 23, 2014 - link
And I suppose everything is derivative these days, except for apple? But it's more like expensive, nicely designed, and not likely to end up in the bargain bin until the next update comes out.Nfarce - Sunday, March 23, 2014 - link
Don't you mindless Appletards have anything better to do?akdj - Monday, March 24, 2014 - link
Ever tried to sell a year or two old Android device? iOS? There's a night and day difference and I use both platforms equally. I upgraded to the 5s and Note 3 last fall. Sold the Note 1 (a pair) for $135. The almost three year old iPhone 4s went for $345 locally on Craigslist. Something to be said for resale and has nothing to do with 'AppleTards' :rolleyes:
