iPhone 6s breaks battery efficiency records, manages excellent score
When we discovered that the iPhone 6s packs a slightly smaller cell — a 1,715 mAh unit — than its predecessor, we weren't sure what to think. The drop of 95 mAh in capacity isn't big, and Apple cited identical battery endurance figures during its presentation. Naturally, then, we were interested in putting the device through our proprietary battery life benchmark and see what happens. We did, and the results are incredible: the iPhone 6s' comparatively tiny juicer packs a mean punch.

We clocked the iPhone 6s at 8 hours and 15 minutes, which is an impressive showing considering the size of the battery, and excellent even if you disregard capacity. In fact, the iPhone 6s actually broke the record for most efficient running, dethroning the Sony Xperia Z3 Compact, which offers amazing battery life relative to the size of the cell within it. And not by little, too: If we assume uniform performance, the Sony Xperia Z3 Compact would have clocked about 13 hours and 30 minutes did it have a 3,500 mAh battery, while the iPhone 6s would push that to 16 hours and 50 minutes — a significant improvement.

Compared to the actual results posted by other, similarly sized devices, including the Sony Xperia Z3 Compact, the iPhone 6s does very well. It trails Sony's golden boys, but leads over Samsung's Galaxy S6 and HTC's One M9. Obviously, you have to account for the 6s' lower resolution, which doesn't impose as high a toll on the cell, but that's that. See for yourself:

Battery life (hours) Higher is better
Apple iPhone 6s 8h 15 min (Excellent)
Apple iPhone 6 5h 22 min (Poor)
Sony Xperia Z3 Compact 10h 2 min (Excellent)
HTC One M9 6h 25 min (Average)
Sony Xperia Z3+ 7h 15 min (Good)
Samsung Galaxy S6 7h 14 min (Good)
Samsung Galaxy S6 edge 8h 11 min (Excellent)
Samsung Galaxy S6 Active 12h 9 min (Excellent)

When it comes to charging times, however, the iPhone 6s posts rather disappointing results, with 150 minutes required to top off the battery. That's significantly worse compared with devices such as the Galaxy S6, which also has a much larger cell, but not quite as tragic as others.

Charging time (minutes) Lower is better
Apple iPhone 6s 150
Apple iPhone 6 147
Sony Xperia Z3 Compact 208
HTC One M9 106
Sony Xperia Z3+ 189
Samsung Galaxy S6 78
Samsung Galaxy S6 edge 83
Samsung Galaxy S6 Active 103

Haha, this is funny. So what was the phone doping, just sitting. If you were actually using the phone, there would be apps using more power of the battery. We know a fact the Internet would use more battery, only second to the display. Also so would some games if you play any. I'm not saying Apple didn't do a good job. I am saying that it looks like you didnt do anything with your device. If you were actually using it, it would be impossible to get 13 hours, because most devices are 5-6hrs SOT

Dude please, just give it a rest. We get it, you don't like Apple products, so move on with your life. And kudos for the "short" essay this time, might be the 1st time I finished one of your comments, or should I say, articles.

I get some 13hrs of web browsing time on my phone (non iphone). However, no one ever uses their phone in a constant usage status. He uses his phone little compared to what I do. I get 18-32hrs off mine with a good amount of usage through the day for those 18hrs. So far my screen brightness is on full, I have played at least 45mins of video, been off the charger nearly 6hrs and I have 77% battery. With how the 6sPlus has done here in our testing, it lasts nearly the same, it is no slouch in battery that we have tested.

Please also note Apple speed of there new iPhones is down to hd as they got there own new format and they not using Emma, but something that like as fast as ufs, but uses ther MacBook controller, no joke, I.e. All the new speed is not down to CPU and also why reviews was saying transfer speeds was faster on files

i know right. This battery test is pure bullsh+t. I said it. Everywhere else I go, I notice that the iPhone 6 lasts longer than the iPhone 6S in some websites, and by a good margin, while other places like Phonearena show the exact opposite.http://wccftech.com/iphone-6s-battery-test-results/ Some how the iPhone 6 with 5 hours of battery is winning against the 6S that has a 8+ hour battery life. I smell corruption...

So what i get at least 12 hours minimum of screen time on my Android phone :) 3 days whitout charging is the minimum. I use it to do all my business calls , 3 email , 2 calender ect ect ect. And i also play about 2 hours of games a day. Its also Waterproof , Dust proof , shock proof and covered by a 3 years warranty thats include physical abuse and liquide damages. For me thats the best phone as its cover all my need whitout slowdown or issues. as for this iphone i will see with my clients if there is a real improvement those battery benchmark are a joke most of the time phone end up with less battery life thats what they say in those benchmark.

They're making a linear extrapolation to guess what equivalent sized batteries in both handsets would be like.

that I understand, but why are they trying to confuse people? why don't they use the actual size of the battery in the z3 compact? ( using linear extrapolation is dumb because it only has x and y, which is abstract in its truest form).

Yes they lasted the same. But consider this. In that same amount of time, the Note is doing far more work. Its running a heavier operating system, then it has the touchwiz layer, plus the S-Pen layer, plus it offers full multi-tasking. A brand new phone is only as good as a phone using hardware that came out 6 months ago really isn't all that great. #justbeinghonest. Think about it. The 6S Plus is pushing half the pixels, its only dualcore and it only has 2GB of RAM vs a battery that is power 4 times the pixels, dual quads, 4GB of RAM and all its other hardware features that the iPhone doesn't have.

Again with the spec war argument. Who are you trying to convince? iPhone buyers don't care if it's dual core and only 326 ppi. The phone works for them.

Posts: 14967; Member since: Sep 25, 2013

They do care. They don't care when they no longer have the advantage. Fact - When the IPS display was the best displays you could buy, all you could hear was, our displays are better and look at the sharpness and how high our PPI is. Now that thet is no longer the case, now you hear...oh you dont need 1080p or 1440p and more RAM and blah blah blah because IOS is optimized to run in less RAM and blah blah blah. When they are losing those things dont matter. When they are Winnipeg they do matter. JUST READ THE POSTS dude. They are all hypocrites. Everything sucks on Android until they themselves has it 3 year later. When Samsung started bring 1280x800 resolutions and now 1080p and 1440p, they all toned down talking about PPI counts. Theier new argument is, whell once you get pass 330PPI you cant see the difference. Well they cant because their eyes have been lookign at crappy displays that use non-standard resolutions. Theer is a huge difference in display when looking at 720p vs 1080p. 1440p doesnt bring a huge difference over 1080p, but you can see significant differences in text sharpness and color accuracy whcih Samsung displays hold best over ALL OEMS period. What you said use to be true, its not anymore. When iPhones had the camera edge, it was the same thing. Now that they dont, they get excited over any feature Samsung doesnt have. For example, Samsung added the ability to take a picture in picture and record audio and some action into a photo. They all said it was a gimmicky feature. Now here Apple is 3 years later WITH THE EXACT SAME THING and oh they love it. Same for features like Burst Shots. Auto-Focusing/with auto-tracking and OIS and more.They hate everything about Android simpky because many things are better, some things are. Apple has lots of advantages over Google, but they arent taking full advantage of them.

The bulk of iPhone 6S buyers won't care about the pixel density of the screen. If they cared that much, they would have moved on to Galaxy devices. Similarly, I doubt many Galaxy S6 buyers noticed that the screen went from 1080 to 1440. It might matter to a small portion of buyers who want either the latest specs or, in the case of QHD screens, VR capabilities. Otherwise it's just manufacturers pushing specs for the sake of more, more, more. And I respect Apple for sticking to what it's good at.

I'm not saying Apple didn't do a good job. They did. I am only saying, that a device that does less than half what you're comparing it too, should do even better. The problem with fans is they only look at numbers. They aren't looking at all the factors surrounding the numbers. Just like this article, the iPhone 6 slightly beat the S6 Edge. Both the S6 Edge and Note have a larger cell vs the iPhone models. We can tell by the numbers that if the S6 Edge has a 1700MaH battery, it would have terrible battery-life considering the hardware inside. What the numbers show for both the S6 Edge and the Note 5 is you can have way more capabilities taxing the battey and still pull off good usage times. If the iPhone's had the same size batter as the Samsung's you are comparign them too, it would again appear to have better battery-life. But the problem is, it should because the iPhone are both pushing a lighter OS, has far less hardware inside, and doesn't have all the same type of features. Which means, if I took the S6 Edge and the Note 5 and stripped it down to the same features at the iPhone and kept the same size batteries as they have now, I could pull off an easy 50% more usage time or more. Look at the numbers in the proper context. Apple did a good job. But a dualcore phone with a lesser resolution, and hardly no features should be equal or barely beating a phone with heavier options.

I get what you're saying, but the thrust of your argument is that specs trump the user experience. You're saying if the GS6 had a dual-core and a 720p screen, it would trounce the battery life of the iPhone 6S. And that's a logical argument, yet one that doesn't hold water because it's entirely hypothetical. Samsung wouldn't put a 720p screen in the Galaxy S6. And the fastest Exynos processors are what they are. They haven't been dual-core in years. The two phones are comparable because both Apple and Samsung mated the right processor to the right screen to the right size battery. Compare what is, not what could be.

Huh? You dont need a quadcore CPU to push 720p. Its not hypothetical. if i took a today's Galaxy and dropped a 750p display on it, it would tax the CPU/GPU less. This has already been proven in banchmarks where the tests is done off-screen. So it isnt a hypothetical.

177. roldefol

Posts: 4744; Member since: Jan 28, 2011

Yes, but the phone itself will never have that screen. You're talking about a hypothetical S6 with lesser specs. It doesn't exist. Compare the real-world iPhone 6S and the real-world Galaxy S6. That's all that matters.
