iPhone 6s breaks battery efficiency records, manages excellent score

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

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)
View all

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.

We need to compare and contrast other credible sites results as well. Just saying, what if every other major credible site scores it lower, then what?

It's already there. 9 hours and 11 minutes. In real life I've gotten more SoT though.

The true battery life will be revealed once ppl start using it and report real status of battery life as parena states are really not truthful when it comes to their iphone baby ...

Um not even close. Lol 1080p is a lot better and more power hungry than 750p.

My girlfriend is an Iphone user. She wanted a rose-gold Iphone and Tmo rep was saying how a lot of women wanted the rose gold phone. I give credit to Apple they know how to appeal to the sheep. They are probably one of the best at marketing... if not best.

So basically, we should ignore all instrumented tests and wait for anecdotal results. And yet we come here to compare specs. I suppose specs and year results don't apply because Apple.

What haters? A marginal increase over the S6 Edge.

But you should consider this. The iPhone is only powering a dualcore, 2GB RAM, 750p display and it only runs one app at a time + Apple apps are the only ones running in the background.

Compared that to the S6 Edge, which is pushing dual quads ( 4 at any one time), a 1440p display, 3GB of RAM, full multi-tasking and more backgrounds apps and services.

I think it should actually be better. Considering Samsung shoved a much larger battery in a phone that is thinner, and smaller than the iPhone. The iPhone should also be housing a 2500MaH battery or reasonably close to it.

The iPhone has always had dismal battery-life compared to other devices with better hardware.

The fact it only slightly beat the S6 Edge is sorta lame.

See how you always try to start flame wars with your lat the haters be silenced?

What's to hate. Yes I hate the iPhone. I hate that it doesn't allow me to do what an Android phone does, and forced me to move away from a device I actually like, because of its limitations.

Enjoy your extra 3 mins over the S6 Edge. While I enjoy doing way more than you in the same amount of time.

I'm only gonna say this. When I was using PA's battery tests as an example, you told me their testing method was faulty and I should only use a place like Anandtech for referencing battery life tests. But now that the iPhone shows good battery life it's OK?

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.

Wow. Just wow. You hate a device because it doesn't do everything you personally want it to do? How about the millions - hundreds of millions - of users for whom the iPhone does everything they need? Takes calls, takes great photos and video, runs games and browses swiftly and smoothly, has a robust app store, and when Apple issues an OS update, everyone with a device from the past 3 years gets it right away. So what if it's not right for you? Just enjoy your pet device and let the happy iPhone owners enjoy theirs.

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.

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

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.

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.

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