Battery Life
Battery life remains probably the single largest differentiator for devices lately, and of huge concern to enthusiasts and normal shoppers alike. We’ve already caught a glimpse of how well 8974 fares from a power perspective inside the LG G2, a device that posted some seriously impressive battery numbers. The Note 3 we’re looking at is also 8974 based since it’s a T-Mobile model, and thus we expect the same kind of battery life.
With this generation of Note, battery gets even larger. The Note started with a then quite large 9.25 watt hour battery, then Note 2 moved to 11.78 watt hours, and Note 3 now moves to a very large 12.16 watt hour battery with of course the newest 3.8V chemistry and all that comes along with it. Display size goes up, but those power gains are offset in other places.
After we talked about the panel self refresh features in the G2 a few people reached out and let me know that this feature has been shipping for a while in some phones, and it’s easy to check for. If we look under the display subsystem we can see that the same MIPI_CMD_PANEL type 9 is used, which refers to this type of interface.
Qualcomm HWC state: MDPVersion=500 DisplayPanel=9
define MIPI_CMD_PANEL ‘9’
Our battery life tests are unchanged and consist of a set of popular webpages that are loaded on a schedule with the display set to exactly 200 nits and repeated until the battery runs out and the device dies on both WiFi and cellular data connections. In this case that means T-Mobile LTE which is 10 MHz FDD in my market, I haven’t had a chance to run the Note 3 on HSPA+ yet, or complete the call test (which is starting to get ridiculous, and probably breaks 24 hours in the case of the Note 3).
On LTE the Note 3 does very well, coming just shy of the pack of iPhones, at just over 8 hours. Interestingly enough it’s just north of the G2s as well, which do have a smaller battery but also smaller display. The Note 3 also is the first device to ship with Qualcomm’s QFE1100 envelope tracker solution from the RF360 front end portfolio, which lowers power consumption by up to 20 percent and heat dissipation by up to 30 percent by allowing the power amplifiers to follow the desired output waveform. There’s more on that later in the cellular section.
On WiFi the Note 3 does better by 22 percent, but not the kind of huge jump I’m used to seeing between cellular and WiFi testing. This tells me the Note 3 battery life is really gated by the display, which is almost always the largest consumer of power in a device. That said the Note 3 does very well all things considered, especially in comparison to the APQ8064 (Fusion 3) phones which came before it, like SGS4. New silicon and new process inside MSM8974 definitely helps move battery life forward here with the race to sleep game.
Charging is an interesting story on the Note 3, but primarily because of what doesn’t change. The Note 3 continues to use Samsung’s tablet charging specification and charger, which has 2 amps of maximum output. The Note 3 draws 2 amps over a considerable amount of the charging curve, like other Samsung devices (in the linear part of the charge curve). USB 3.0 doesn’t change things up here quite yet with the new supported charge voltages that are coming eventually with the power delivery specification.
The Note 3 does charge faster overall compared to the SGS4 however thanks in part to the new PMIC (PM8941) which is part of the overall 8974 platform story.

Hmmm… it seems to me that almost all of the commenters here, are Americans; thus, a certified Apple Fanboys!, and this certainly includes Ars Technica, AnandTech and many others! That, is the very reason why, all product that is needed to be reviewed (as the market demands), those are which directly competitors of Apple, especially Samsung, for sure; all possible types of professionally conjured praises shall certainly be provided just to pelt there most hidden agenda of wanting the very downfall of Samsung, believing that by doing so, Apple products specially iPhone 5S and beyond, will go up again to the top, hoping to become again the number one selling Smartphone of 2013 and beyond! Oh come-on…, don’t be too obvious, and envious!!!doobydoo - Saturday, October 19, 2013 - link
Dude you're the only one on here who seems to have issues. And Anandtech is a fully international site with an international audience.akdj - Wednesday, December 11, 2013 - link
You should get a first name....'Stop'....and maybe add an 'ing' to the end of your handle here. Where did this completely off the wall comment come from? Left field anyone?Anyway...sorry to let you in, the 5s isn't hoping....it's happened. 'Again'. Number one selling smartphone of 2013. Doesn't mean much. There's a LOT of choice outside of the limited iOS world....which with choice and expanded options will always make it tough for even the largest and most successful OEMs ala Samsung to best them with a single product to product comparison.
It's a good, no.....a GREAT thing to have such phenomenal competition between vendors. We're the beneficiary....seems like overnight we were able to put the power of yesterday's laptop in our pocket! These things SCREAM! The 5, 5s, Note3, G2, S4---it's funny to me ANYone that appreciates and enjoys technology so much could be against one or anti the 'other'. Between the pair....or in each the Play Store and the App Store have more software available than anytime in history for ANY computing platform....and comparing the Note 3 to it's older, two year old sibling....improvements I'm computing and graphics are in the neighborhood of 1500-2000% increases! That's blowing Moore's law out of the water man!
Enjoy them all. Buy what you can. But don't spew bullshit on websites beyond your comprehension and knowledge. Just kinda 'outs' ya as a dumbass....at worst, ignorant at best. ;)

Name and shame - once the PR for getting caught doing this has more impact then the positive PR you gain from cheating it'll stop.Squuiid - Tuesday, October 1, 2013 - link
Anand, as it stands, this review is a farce. All it is doing is encouraging Samsung to continue it's deception. If reputable sites such as your own don't call this out and make a big fuss about it, then why would they stop? We all know Samsung's ethics are rather questionable as it is. Let's not encourage them.Anand Lal Shimpi - Tuesday, October 1, 2013 - link
We did call it out in the review. The problem with only circumventing it on the Note 3 is that other devices do it as well. We can work towards circumventing it everywhere, but we can't selectively choose when to enable/disable it.Chillin1248 - Tuesday, October 1, 2013 - link
Then don't bother benchmarking it then. If you can't come out and say that the numbers listed in the benchmarks reflect the Device's User Experience, then don't bother benchmarking them. Just leave the page blank.What you are doing is condoning fraud. This is like the manufacturer of a car giving you a car to test, just that when the GPS detects that you go o the racetrack to test the speed of the vehicle, it switches to a brief higher power mode that would never be presented otherwise to the consumer and is unsustainable long term. (you get the drift)
By publishing the benchmarks, you have only condoned the practice you claim to disdain.

I agree. Frankly, the attempt to minimize/brush aside the blatant cheating Samsung is doing has me questioning Anandtech's objectivity. Even if it's not possible to catch the cheaters every single time, that's no excuse for letting them get away with it when it's a major impact and doing so is trivial to do.bubblesmoney - Tuesday, October 1, 2013 - link
surely they will tread carefully on pointing out the bad points, thats the quid pro quo for getting access to devices before they are released to the public. Their reasons for treading softly on this issue and the region locking issue is obvious.I know they briefly mentioned region locking, but isnt a hardware site actually meant to mention that a phone meant for power business uers actually being gimped and a so called business phone wont work abroad as it will ask for an unlock code when a foreign sim which is in the MCC list wont work for making calls. only way it will work is using costly roaming. Nice way for samsung to shaft its end users and get nice kick backs from networks to samsung so that their network gets preference as to what is blocked and what is not. see proof of region blocks with links on my posts on the trustedreviews article http://www.trustedreviews.com/opinions/galaxy-note...
