Battery Life

One of the big draws of the larger form factor is battery life. Due to fundamental scaling issues, a bigger phone should be able to achieve greater battery life than a small one. This is because a smartphone's PCB generally remains constant in size, so it becomes an increasingly smaller proportion of the overall device size. This leaves increasingly large areas where batteries fill in the gap. In order to quantify just how big of a difference this makes when going from 4.7" to 5.5", we turn to our standardized battery life test suite. For those unfamiliar with our testing, the display is calibrated to 200 nits and all background tasks are disabled in order to ensure that only the foreground task is active in our tests.

Web Browsing Battery Life (WiFi)

As we previously discussed, the iPhone 6 Plus performs quite admirably in the WiFi web browsing test. As expected, there's a healthy bump over the iPhone 6, but it's not quite a massive leap as a larger battery size might suggest.

Web Browsing Battery Life (4G LTE)

Once again, we see a similar pattern with the LTE web browsing test. Since both phones are based on the same platform, it makes sense that their results track quite closely together as we're only scaling display and battery size within the context of these tests.

However, the web browsing test is a mostly display-bound test, even if there is an SoC efficiency aspect that can make a significant difference. In order to better test SoC efficiency and get an idea of the dynamic range that a phone has in battery life, we turn to our compute-bound tests. Unfortunately, Basemark OS II stops the test too early due to low battery notifications in iOS, so we cannot use that test for a proper comparison to other phones.

GFXBench 3.0 Battery Life

GFXBench 3.0 Performance Degradation

As shown in these charts, the iPhone 6 Plus manages to sustain a significant boost in battery life when compared to the iPhone 6, and performance is almost identical as well. It seems that the iPhone 6 Plus begins to throttle towards the end of the test simply because it has more time to generate heat rather than any real difference in cooling, as skin temperatures were also around 43C on the iPhone 6 Plus in this test. It's also important to note that the iPhone 6 Plus is rendering at 2208x1242 internally in order to keep proper scaling with the 163 points per inch system that iOS has, which accounts for part of the performance delta.

Overall, battery life on the iPhone 6 Plus ranges between about 20% higher to 40% higher depending on the balance of display power and SoC/baseband power in any given situation. Heavily display-bound situations will be closer to the 20% higher figure while more SoC-bound tasks will tend toward 40% or even higher. Purely idle situations should see even greater improvements as any situation where the display is off will see linear scaling with battery size.

Charge Time

Charge time is one of the key metrics for getting a holistic picture of battery life, as it's impossible to really understand whether a phone will be able to stay mobile as needed without considering recharging. In some cases such as a trade show or travel, it doesn't matter if a phone lasts 20% longer than the competition if it loses all the time gained in time spent on a charger. In order to test this, power is tracked from when the phone is connected to the charger to when it reaches the lowest power draw state on the AC adapter.

Charge Time

Unfortunately, the included charger is the same 5W charger that we've seen for years now. As a result, the iPhone 6 Plus is constrained by the relatively low maximum power that it can put out. Those that wish for faster charging should look into getting an iPad A/C adapter as the iPhone 6 Plus will charge faster when connected to it.

    you know what?, hmm I guess you don't anyway… to all passionate but very insecure Apple fan-boys out there pretending not to be?, I feel so pity on you… and I sympathized so very much with your utmost agonies and sorrows……… and even much difficulties justifying the shortcomings of your iPhones. just to inform the Apple employee who also happens to be the owner of this website, I am not, and surely not, a Samsung employee, nor even affiliated to them in anyways possible! the only reason why I prefer the two Galaxy Notes of Samsung is because, they are the latest, they have the greatest, AND, they have the most technologically innovative products, scientists and engineers this world has to offer right now! Isn't it that hard to understand?…, either you honestly don't know, or you just can't accept the truth. google it, so that you will know, who is the top 10 countries in the field of mathematics right now, if you want to know why Samsung is leading when it comes to technological innovations today…, the why behind the what! So don't call me a Samsung fanboy, for I only wanna have the best, the latest, and the greatest for myself, and nothing else!…

    @Hook Em14: me, a clown? Really… do you really insist? Well if so, OK… yes, I certainly am… and I am even more than happy, and very-much more than willing to give you, and to all other Apple fanboys like you, more things to enjoy, things that can ABSOLUTELY make you, Laugh, Out, LOWD! It's gonna be Fun Fun Fun…

    Are you envy with Samsung? Cause if you are, this thing is absolutely not the right one to respond! If I may suggest, call Apple, and tell them to make a flexible display, instead of a bendable device! Are you now having fun?… did a "clown" make you, LOL?, or maybe, broke your heart into pieces.

    Great review, as always! Anand was telling the truth! This is still a trustworthy website.

    I'm still waiting for my 6+ (coming 3-4 weeks). This is my transition from my old 4s. Around me, there are iphone users leaving for android as well as android users leaving for iphone. I guess it is about choice, task and maybe also brand loyalty.

    Personally, I think I would not consider leave iPhone for Android this year. I need a lot of applications on my device and Apple is treating their application developers really well, then this results a lot of great apps on iOS. This, in my opinion, is the strongest motivation keeping me stay with iPhone.

    Android is growing. But it still cannot provide me the great application experience as I get from iPhone.

    "I guess it is about choice, task and maybe also brand loyalty."

    You are definitely right Sir Golfmann. But you know what triggered me to react and commented this way?, because of these remarks from a supposedly, fair WEBSITE!:

    “The first is that in the case of the iPhone 6 plus, there appears to be an area near the bottom of the volume buttons that is a weak point as we see a clear failure of the casing in this area. However, it seems that there is a significant amount of force needed in the first place in order to cause permanent deformation."

    REALLY?!? Just take a closer look and see how fair and unbiased this website is as they claim, at least when it comes to Apple of course:

    “"Now kids are doubling iPhones in Apple Stores: boys age 15 put the stress test at 6 Plus - and break into the process

    Video shows teens Norwich Apple store bending Phone

    They use so much pressure that the phone display is out

    The boys take a shop worker if an iPhone 6 plus can double

    Apple employee denies the claim saying it is a "internet rumor’

    Apple has acknowledged that there are problems with the new iPhones bending

    Cupertino-based group says it has received nine formal complaints

    To prove the claims, Consumer Reports (CR) used 'three-point bending discovered test'CR HTC One (M8) and iPhone 6 are the weakest phones

    Rumors about Apple iPhone 6 Plus bending show no signs of dying down.

    Now two teens have decided to defect reports of alleged phone in their hands.

    In a five-minute video, two boys of 15 years old, walk into an Apple store to try to bend a gold iPhone 6 Plus.

    They use so much pressure that the phone display is out, making teens who say they have to flee or “would have ended up paying for it."

    The boys, who are considered to Norfolk, then ask a store worker whether or not it is an iPhone 6 plus could bend.

    It is believed that the thinner pattern, and the use of aluminum metal in the design, makes the frame to deform.

    But Apple employee denies the charge saying it is an "internet rumor."

    One of the teens involved in the video says: "The reason why we were laughing because it was really fun.”

    "We were at the Apple store bending and breaking your iPhone, which I guess is a criminal damage, but I do not care, to be honest.”

    "It's not Apple's fault - they are false advertising, saying it's the best iPhone but clearly it is not whether you can fold in your hands or pocket is ridiculous.."

    The duo are not the only ones who try to bend the iPhone 6 Plus, with reports suggesting damaged iPhone can be seen along the Apple stores.

    Some customers have even tried to bend the supposedly less prone iPhone 6 Apple has not commented on the matter.

    Apple has acknowledged that there are problems with the new iPhones bending in some circumstances, but added that he has only received nine formal complaints.

    The experts at Consumer Reports recently suggested some of these claims may have been exaggerated.

    During their own stress tests, they found the iPhone 6 plus can withstand more force than was previously claimed - and more robust than the HTC One (M8) and the smaller iPhone 6.

    The first reports of iPhones bendy began on Wednesday last week when photos appeared online showing the top of the device out of shape.

    YouTube user Hilsenteger Lewis then published a video showing the iPhone 6 Plus Flex using just your fingers, which has already been viewed over 45.3 million times.

    To put these claims to the test, Consumer Reports used a so-called "test three point bending."

    This involved telephone support at two points in each end before applying a force on the top of the device.

    Besides the iPhone 6 Plus, the researchers tested the iPhone 6, HTC One (M8), G3 LG, Samsung Galaxy Note 3 and iPhone 5.

    Despite the claims, the HTC One (M8) and iPhone 6 devices were the weakest.

    They began to warp and bend when a total of 70 pounds (31.75kg) of force was applied.

    The iPhone 6 Plus was third, at 90 pounds (40 kg), followed by LG and G3 iPhone 5 at 130 pounds (59kg) and the Samsung Galaxy Note 3 150 pounds (68kg).

    The iPhone 6 Plus results show the phone can support 15 pounds (6.8 kg) more strongly than initial reports suggested.

    Consumer Reports said that this is more than one fourth of force needed to break three pencils.

    Apple to criticism and complaints last week about its iOS 8.0.1 update is also faced after it caused problems with sensors TouchID new phones and data services.

    The update was withdrawn, and the problems that now must be resolved by updating to iOS 8.0.2.

    Following the reports, and the controversy #bendgate Twitter, Apple spokeswoman Trudy Muller said: 'with normal use, a curve is extremely rare and iPhone through our first six days of sale, a total of nine customers have contacted Apple with a folded iPhone 6 Plus'

    Apple shares closed almost 4 percent to $97.87 (£ 60.26) Thursday, ending nearly $23billion (£ 14.1billion) in market value."”

    and then here is Marques Brownlee, trying at His utmost best, to somehow, possibly justify; as clever as He could (to not become sound obvious of course), by suggesting an alternative, to put it in a case, which will for (the) most obvious reasons, add another investment for guess what, A.P.P.L.E.'s GAIN!

    #2. Still accusing… but this-time, excusing; and defending as-well!

    Defence and Excuse #2-a. "It’s clear that in the case of the Galaxy Note 3 that a great deal of the structural rigidity is tied to the display itself, so the case doesn’t quite provide much in the way of protection as the polymer used is clearly in the elastic region all the way to failure. LG seems to have a different design though, as their polymer material has a clear case of brittle failure at the limit, which saved the display from shattering."

    Excuse and Accuse #2-a/b. "It's certainly possible to bend the iPhone 6 Plus (or really any phone or tablet), but the real issue here that hasn’t been addressed is the level of force needed to cause a certain level of elastic or plastic deformation in the material." Really.

    Defence and Excuse #2-b/c. "There’s also no mention of force per unit area in any of these figures, so we can’t really have a serious discussion about this issue without the necessary data."

    Defence and Excuse #2-c/d. "Unfortunately, the included charger is the same 5W charger that we've seen for years now. As a result, the iPhone 6 Plus is constrained by the relatively low maximum power that it can put out. Those that wish for faster charging should look into getting an iPad A/C adapter as the iPhone 6 Plus will charge faster when connected to it."

    #3. This time, not only Excusing and Defending; but also, Promoting and/or Advertising!!

    Promoting and Advertising #3-a. "Those that wish for faster charging should look into getting an iPad A/C adapter as the iPhone 6 Plus will charge faster when connected to it." Ohs, you mean every iPhone 6 plus users must need to buy an iPad to possibly enjoy faster charging? Why are they just didn't include the necessary A/C adapter in the first place!

    Promoting and Advertising #3-b. "While the software differences are definitely smaller than what we see on the Galaxy Note line, Apple has managed to do enough that most won't notice a significant difference one way or another." Sure?

    Promoting and Advertising #3-c. "Even though this seems to be the only application of OIS, Apple has managed to make the overall camera experience better in a way that ("no other OEM has")."

    Promoting and Advertising #3-d. "Once again, it's pretty easy to see the strength of Apple's integrated hardware and software approach as it's only a matter of time before most applications take advantage of the iPhone 6 Plus' additional screen size." Hmmm. As per Jonathan Morrison, and to others who know and have the inside knowledge about the Apple P.R. thing, to Anand and Joshua Ho: how-much are your commission on this review?, and for defending and promoting the iPhone 6 Plus in the most clever ways possible, in the name of (Fair), (Honest), and, (Unbiased Review)? Can I have some?, so that I can buy the Galaxy Note Edge and the Galaxy Note 4 on October 17? Heheheheh kidding aside; for I know you won't anyway…

    Hmm but wait, there's more; actually, one more:

    Promoting and Advertising #3-e. "If you have to buy a phablet now though, the iPhone 6 Plus is the best one available." Tremendously Perfect indeed!…

    …Now, anyone still, call me a Samsung fanboy? Shame on you!

    @pliablemoosethebanned, are you stating facts, or just trying at your hardest, to defend iPhone 6 + no matter what. Can you boldly say and proclaim that you, are a proud Apple fanboy?, and claim that what we are reading here, is the fairest of the fair, and the most unbiased review? before you give to me the nastiest reply you, Apple fanboys can ever possibly do, out of your frustrations of course, you may wish to take a look at this, for your education:
