Battery Life
Battery life is undoubtedly one of the most important aspects of any smartphone. However, battery life is an enormous subject, and while it may seem simple on the surface there’s a great deal of underlying complexity. In order to try and cover the full breadth of use cases, we start with our baseline test, which is now the web browsing battery life test. In order to try and control for extraneous variables and get a good relative comparison, we standardize all displays to 200 nits on a full white display.
Our first test is in WiFi web browsing. As we can see, the iPhone 6 puts up a surprising showing for a phone with such a small battery. If anything, it seems that Apple leaned towards the conservative side in their advertised numbers as we managed to get higher than expected battery life. It may seem strange that the iPhone 6 achieves such a strong showing despite the small battery, but this is because the test is designed to avoid penalizing a phone for having a faster SoC or data connection.
In LTE web browsing, we see the same story. The iPhone 6 is about equal to or better than the competition, which is in line with what we would expect given the cellular architecture. In the case of the iPhone 6 and most other flagship smartphones this year, components such as Qualcomm’s QFE1100 envelope tracker, WTR1625 transceiver, and MDM9x25 modem have managed to make LTE power consumption approximately equal to WiFi power consumption. With the deployment of category 6 LTE and next generation RF components we could see LTE battery life exceed WiFi battery life.
While the web browsing test gives us a good picture of battery life in display-bound tasks, intensive use tends to be more SoC-bound. In order to see how phones compare in SoC-bound workloads, we turn to GFXBench, which has an infinite looping test. This test also provides a good idea of nominal performance. Unfortunately, for now we cannot report an accurate Basemark OS II battery life score as the test will stop when low battery notifications pop up on the screen. We are currently investigating methods to bypass this issue and report a final score in the near future.
In the GFXBench test, at first it seems that the iPhone 6 is one of the worst for battery life under sustained load. However, once we look at the performance degradation over time it makes a lot more sense. This seems to be the type of workload that Apple referenced in their presentations, because this is the first phone I’ve seen that successfully does a full rundown without actually throttling. Of course, this does come with high skin temperatures. The phone definitely gets hot, but not uncomfortable. Using a FLIR camera, I saw peak temperatures of around 43 degrees Celcius, so it definitely doesn't exceed 50C in most conditions.
Normally, I would expect a 4.7” class smartphone to need a battery around the size of the HTC One (M7) or Motorola Moto X (2013) to keep pace with phones like the One (M8) and Galaxy S5, but Apple has pulled it off with a battery that is much smaller. There are two key factors that we can point to in this case. The first is the display, which can avoid pushing the LED backlight towards the higher current region that is much less efficient. This is because the amount of light-blocking circuitry is reduced and the active area of the display can be higher. The second aspect is the SoC, which is on a lower power 20nm process node. While TSMC’s 20nm process doesn’t have FinFET, improved silicon straining and high K metal gate make it possible to drive down active power and leakage when compared to 28nm processes. It’s also likely that the A8’s architecture is more efficient than other SoCs we’ve seen this year. However, it's important to note that without a capacitance and voltage table or something similarly concrete we can't really prove this statement.
Charge Time
While battery life determines the time spent away from a charger, the time spent attached to a charger is just as important. Even if most people charge their phones at night, there are plenty of cases where people don't have at least five hours to spend charging their phone. For example, forgetting to plug the phone into a charger before going to sleep or charging a phone between connecting flights are all times when charge time becomes crucial. In order to properly test for charge time, charge time is measured as the time from when the phone is connected to the charger to the time when the A/C adapter reaches its lowest power state with the phone still connected.
As you can see, the iPhone 6 performs reasonably well, and ends up in the same range as the iPhone 5s. The iPhone 6 Plus ends up on the high side because it ships with the same power adapter as the iPhone 6, which can provide a maximum of one amp at five volts.
Fortunately, based on the USB device information for the phones, both the iPhone 6 and 6 Plus support charging with power adapters like the iPad charging block that can provide up to 2.1 amps at five volts. Using one of these chargers will dramatically reduce charge time on the new iPhones, and it's a very worthwhile investment (assuming you don't already have an iPad) for the iPhone 6 Plus in particular.

A good phone runs its own OS.You and that moron don't understand HD so your obsession is invalid.

He isn't wrong about anything he said, but I just can't imagine getting worked up enough to say it. As a current Apple user/developer, I have every Apple product. I like their stuff, but I can't say I am obsessed about it. I also have a lot of the competing products, so I am constantly toying with all of them. When my current iPhone breaks, I will probably replace it with a Sony Xperia Z3 compact, because it looks like a perfect phone for me. I am not interested in a bigger phone and I would like something that is waterproof, because I run or ride a rain, sleet or shine. I personally think Apple is falling behind in the world of business and multi-use devices. I am seeing a lot of customers whom I developed business apps for iOS coming back and wanting to move to Microsoft or Android platforms because the devices are more powerful and offer more robust features.GerryS - Wednesday, October 1, 2014 - link
I agree. He makes some good points, though most of them are seriously overstated. For most users (yes, nearly everyone in my experience) a "pretty dang good" display is about as good as we can be bothered to look for. I actually like the display on my iPhone 4s. I've never had a complaint, except that it is small, so I got an iPad.See, I don't actually like it that Apple went for big phones. I carry my phone in my pants pocket. The 6 might be about the limit of the size phone I want. If I could get an updated 4s with the processor and other basic features of the 6, that's what I'd buy.
So, for most consumers, we want something that works. I had 4 Android phones before Verizon got the iPhone. I liked them pretty well, but they kept breaking. I went to Apple for dependability, and have not been disappointed. I've only had a couple of problems (even with my jailbreaks), and they've always been easy to fix.
I do like it when Apple leads the way, but it would be silly to expect them to have all of the advances. So many people compare the iPhones to Android phones, listing all of the things that came out first or "better" on Android phones. They seem to forget that there are dozens of companies making Android phones. The best of them have only one or tow innovations at a time - about the same as Apple manages. Apple continues to be one of the leaders, as long as you compare them to one company at a time.
If you want the universe of advances coming from Android manufacturers, then go buy an Android. We really won't hold it against you. For me, I like my iPhone and iPad. My wife has Android (at my recommendation) because we could get some features that were important to her.

Lol, he is wrong about his engine analogy! Seriously, none of that makes any sense. Haha, and what's a "V8 compressor"? My goodness...people shouldn't talk about things they really don't know. Just reading that was cringe worthy.sigmatau - Thursday, October 2, 2014 - link
I'm going to guess you are not so dense as to be picking at the spelling but instead don't know what is a v8 Kompressor. Not only one of the best engines that Mercedes made, but also award winning by 3rd parties.techconc - Thursday, October 2, 2014 - link
Actually, he is either wrong or extremely misguided in almost everything he's said. Feel free to pick your argument of choice. He starts off by saying how the iPhone 6 launch was disastrous. As compared to what? What other vendor will sell 10 million devices on a launch weekend? Even for Apple, it broke their own previous records. I'm genuinely grateful for people that prove they're an idiot right up front. It lets me know I can either skip the rest of the post or read on for purely amusement purposes.That's just the conceptual part of the post. His technical observations were equally misguided. Especially with regard to screen quality, etc. Clearly he didn't bother reading the Anandtech review he's commenting on.

@techconc: Sure, what other products you know starts to bend, or totally crap out after the first buggy update, or even have features withdrawn due to more bugs all within the first week of release?akdj - Friday, October 3, 2014 - link
Really? You're still convinced the iPhone (6 OR 6+) actually and easily 'bends' in the first week? Buggy update? The one available for about two hours that few downloaded and within ten hours of pulling it a fixed update was released? Features withdrawn? I'm intrigued ..as an owner and realist like techconc, the person you responded to... I've GOT to know!I'm patiently awaiting my pair of 6+s for my wife and I. We just returned from the mall and the Apple Store specifically playing for almost two hours with them. I built a two minute movie and. Rendered in 1080p in about 35/40 seconds, air dropped to myself. Un. Believable phone. It's. Amazing
We ordered launch day through our business representative. Lol. Silly me. Ship date estimate is pretty specific, actually a bit ambiguous with the latest update. 11/2-11/28/14:-)
Oh well. Plenty of time to allow developers to continue updating their apps.
Between my Air, rMBP 15" and the iPhone 5s /6+, my business of 27 years has been revolutionized. Literally, over the past half decade, as a pilot and sound/video producer...weight savings alone are enough to double our profits. And ½ our setup snd break down times. Even my 'flight bag' of nearly fifty pounds isn't necessary. With three retina minis in the cockpit for redundancy, the 'paper' is still there, but unnecessary any more for updates to plates and Jep charts, winds aloft and weather/traffic ...even diversion airports, filing my flight plan and telling me how thirsty she is! Fuel calculated, with a GPS dongle a tenth the price and 100 fold quicker to lock n track than avionics just a half decade ago provide incredible accuracy. ADSB and TCAS (3D terrain, weather and other traffic/with their specific info; altitude, speed, heading, and Xspnder --- TCAS, a warning system that 'tells you what to do' in conjunction with other planes fitted with the system including all commercial traffic and many GA pilots with ILS certifications ...Alaska can get nasty quick and having to 'duck down' these two systems alone are incredible and 'reasonably priced' advancements!).
I'm not sure there's a place in my life iOS has t changed. As a father, business owner and operator, little league and wrestling coach, and pilot...each iteration has improved signficantly enough in 'most situations' to justify yearly updates for me. iPhones hold their value. Until the 4s, AT&T was generous and 'allowed' a 12 month subsidized update. With the business I also provide 17 full time employee iPhones so we've been lucky enough to 'recoup' some of the money spent each update
I just sold an employee's iPhone 5, 32GB AT&T with a cracked screen, scratched to hell and working perfectly. With excellent battery health and perfect camera lens (only scratch-less area of the phone!) for $235 to a local repair guy. He saw me in the mall with the Gazelle box (more than a hundred bucks less) on my way to the USPS. Asked what I was sending. Told him. Showed him a 'picture' or seven before I unboxed it, but he was adamant ...he was able to shine it up with his pieces n parts for $45 or less! Told me it would cost a customer about $210 to do the work but parts were 20% the cost ...labor and time is the price. From there he was confident he could sell it for $325-350 at his kiosk within 24 hours.
My son has had his fifth generation iPod touch for two years. He's nine. No scratches. No scuffs. Clean a booger or twelve off once a week but other than that, it's completely 'perfect'. These iPhones are built damn near the same. Sleek, thin and well balanced ...no bugs, incredibly quick and unless you're a dumbass and put your $800 pocket computer in your rear pocket of your jeans and SIT on it, you're an idiot ...and you've got to be SIGNIFICANTLY overweight AND hit the precise angle in order to 'mash' 100 pounds of pressure to a 'single point'/torque.
Can you bend em? Yep. It's been proven and EVERY piece of proof we've seen visually demonstrates the incredible amount of force necessary and in such a way not indicative of daily use or situations a consumer would find themselves in 99.9% of the time.
Don't. Be. Silly. I respond not only to you but to all those talking like you. Until you've used one. Felt one. Actually spent time with it, it's difficult to understand.
These are absolute and unequivably the BEST two phones on the maket at this time. With the best and most abundant apps/software optimized to its specs. Support to back it up. And resale value when Ya get bored and ready for a new one. You'll recover your 'down payment' plus fifty percent in many cases ...if you take care of it. Seemingly, they're even more valuable than a same year flagship Samsung Note 2, as I wasn't able to get more than $125 for that joke. Note 3 got it right. But it took twice the cores, clocked at twice the speed with three times the memory ( ⅔ to ¾ of which is in use even without an app running! I've got one though and don't take me wrong, I love it) to get 'close' to the GUI fluency of the iPhone & iOS
That's. SAD. That's. Buggy. I'd much rather have a phone that bends with a hundred pounds of torque in a certain and specific area than I would gambling I'll get an update, deal with carriers and OEM bloat and shitty aesthetics and design. Lack of support or resale, lack of apps and software ...& the apps and software in parity are incredibly more enjoyable and stable on iOS. I like my Note for browsing and the SPen. I think an active digitizer would put the six plus over the top but as it is, it's perfect.
Indeed, I'll continue using (& owning) my N3. But I'm not the least bit compelled with the '4' and its 2540 display. While I'm sure there's noticeable and 'obvious' benefits to having 550/600+ PPI ...I'll warn ya when you're 38-42, speaking from experience...you'll need 'cheaters';) ...like our ears, our eyes deteriorate as well ...the elasticity of our lens and ability to change and 'maintain' up close focus just ...goes away! Hence the incredible benefits I've found witg the HiDPI display technology. 3D? Good riddance! It was a joy to see 4k/Ultra HD and even examples of 5/6 & 8K motion display AND capture gear instead of dumbass glasses and crappy off center viewing with limited content.
Apple lead the way and destroyed multi billion dollar monsters in the industry with the iPhone. They then changed consumer display technology's availability. HiDPI and increased resolution is awesome. But to a certain point. Your 1080p 65" LED LCD IPS or AMOLED TV in the living room at 10-12 feet or typical viewing distances is around 100ppi. Quadrupling the resolution (4k) while not exactly linear, will amount to approximately an increase of 100%. To 200ppi. Not four foukd as you may think.
The 'new' ipad(3)/4 -- iPhone 4 -- the rMBPs --- ALL Game Changing home runs. Putting a certain 'joy' back into 'work' again. With SUCH an accurate palate and the ability of OS X'es scaling of the UI (& third party apps the same ...utilizing pixel for pixel when necessary or quadrupling for the GUI simultaneously and without 'glitches' or latency is a marvel in engineering. Coupled with the IrisPro 5200/750m and PCIe SSD at a TB with read and write speeds exceeding a Gb/s, Thunderbolt 2 and its 'one' cable capabilities and abilities to run multiple 4K displays ...shoot man. Seems like yesterday I was hunting the wax pencils and cutting my fingers slicing tape ...now it's immediate and fast as hell in a four pound package at a dozen times the resolution.
Times are good if you're an Apple user. And thats JUST the hardware!
OS X and iOS's march to marriage is incredible. Continuity and Handoff. Air drop between iOS and OS X, as well ...the aggregation and integration between the devices you're using is revolutionary. Period. Only Windows has the power and support vertically and horizontally to compete with what Apple's doing. Vertical & Horizontal backbones.
No one that needs to 'work' is buying a Chromebook

This must've been the longest and weirdest Iphone ad I've ever read. ;-)techconc - Monday, October 6, 2014 - link
@shm224 - I now know several people with iPhone 6 and 6+ devices that keep them in their pockets. They all seem to agree that there is no merit to this "bend gate" nonsense. While nobody doubts that these phones can bend under a certain amount of pressure (90 lbs. according to Consumer Reports), from a practical matter, it's a non-issue. Further, I find it rather interesting that phones such as the HTC One which bend under significantly less pressure (70 lbs.) don't receive the same sort of media attention.As for the 8.0.1 update, yup, Apple screwed that up. Fortunately, for Apple, the update was pulled after about an hour. It's also fortunate that in only affected some phones and only for the over the air update as opposed to the iTunes update. To your point, no, this typically isn't an issue for other phones... then again, neither are regular updates.
