The pont is, it takes many, many times as much power to transmit a radio signal than to receive. And then don't forget that the BT antenna is omni-directional. It needs to transmit enough power for the receive to be anywhere in the room, so the vast majority of its power is just wasted.

That is not true.

Cellular basestation transmissions are directional, using a variety of technologies. Some, use sectored (180, 120, or 60 degree sectors) directional antennas, others use beam forming techniques through signal processing. The greatest capital cost in a cellular basestation system are RF power amplifiers, generally representing 30% of the overall cost. Transmitting omni-directionally wastes power, requiring larger power amplifiers and greater electricity usage. It's just not done.
 
That would be a good approach by apple to justify not focusing on look of the next iPhone. Then again, it seems like before any new iPhone launch, these types of rumors come out but we never see a big different in battery life.
 
So what are you saying? People who want to use the "powerful desktop class cpu" and gaming capability Timmy is always raving on about should leave Apple?

The iPhone is designed for people who keep it in their pocket so much they get 2 days out of the battery and people who want a phone to actually get some use out of should switch to Android? iPhone is a fashion accessory not meant to be used. Android has all the functionality.

Is that what you're trying to say?

If the iPhone does not meet your gaming needs, i.e. getting no more than 90 minutes on a charge before the battery is depleted, simply find a phone that does. If there's an android phone out there that does that, simply buy it and get your life back.

More capacity does not mean better. iOS can become more efficient with same battery. Same for screens.

14% is not perfect but it is improvement.
 
A pretty safe bet to rumor-leak a next-gen smartphone is going to have increased battery life -- could be used as a rumor-template for any smartphone, Apple or not...

Next up, the iPhone 7 is rumored to have a different processor than the iPhone 6S o_O
Devices might get increased battery life but when the phone is the same size, the battery capacity in newer generations tends to fall because they are trying to cram more processor, camera, and other new components that weren't there last time. This is why removing the headphone jack actually helps a lot.
 
Water resistance, thickness, digitalization.

Other phones have water-resistant 3.5mm headset jacks. Other phones have thinner bodies while still retaining the headset jack. The Lightning port will still remain, and would be the digitized audio port regardless. So, none of what you said works.

What does a cellular basestation antenna have to do with a bluetooth antenna in your iPhone?

Or, since we still live an free country, I can voice my displeasure at Apple's poor design choices and then buy whichever phone I feel best suits my needs. If my criticism of a for-profit company offends your sense religious zealotry, I suggest you either rethink your life or move to a country that doesn't have a strong tradition of free speech.

I like Apple overall. I hate Timmy and what Apple is currently doing. I am free to say that.

If the headphone pictures are at all legit, and are terminating (no pass through for power to connect) then I'm going to need a lot more than 14% to be worth ditching the headphone port. If the new battery can't go 12 hours of consistent us playing music and talking on the phone then it's not worth it.

First of all, if these are legit, it's what Apple is giving you for free. I personally have never used headphones while charging my phone. So I suspect most people are somewhere between you and me. Therefore, if your needs deviate from the average, and you need a pair of headphones that allow simultaneous charging and listening, then you'll need to buy a pair that suits your needs. As for the practical battery life the extra battery capacity may add, well that all depends on you and your habits. If you're a habitual games player, or otherwise heavy wireless user, then it doesn't matter if the battery life lasts 12 hours while only listening to music and talking on the phone (by the way, no iPhone lasts 12 hours of talk time now). So then you buy what suits your needs -- perhaps that's a battery pack, perhaps that's a pair of headphones with a pass through. And that's assuming that Apple doesn't provide another method to charge the phone as has been rumored. Or, that Apple doesn't offer you a new charging brick with a Lightning port and a USB-C port.

Other phones have water-resistant 3.5mm headset jacks. Other phones have thinner bodies while still retaining the headset jack. The Lightning port will still remain, and would be the digitized audio port regardless. So, none of what you said works.

Well


The S7 manages to have all three, so you don't sacrifice anything!

I'd like to see your spreadsheet analysis of all of those other water-resistant phones that demonstrate they have all of the same or better features as a comparable iPhone, including performance, battery life, and dimensions. Because it's not a fair comparison if the phones aren't equal in every way. And I guess we'll just ignore that those droid makers have been lying about water resistant as the recent consumer reports article proves. Some of those phones fail the minute they touch water. But hey it makes a nice story to support your case if it were true, and if Apple had said anywhere that removing the headphone jack in any way was primarily to improve the water-resistance of the iPhone.
 
I see a lot of people here claiming poor battery life. So why don't you all post up screenshots of your battery usage stats from your iPhones and show us how poor your battery life is (and let us see what Apps are consuming all that power).
Please post yours. They should look interesting

We're talking about individual features, not the device as a whole, so comparing irrelevant features is, of course, irrelevant. If others can do it (and do it well; you're making a report about one phone speak for every other phone with some sort of water protection, something that no iPhone can even remotely touch), there's literally no reason why Apple can't, other than to add a new line of revenue by charging for adapters.
 
Wow, you sure do start a lot of your posts with "Wrong", which is funny because once again you have no clue what you're talking about. The battery life used to receive a radio signal has nothing at all to do with the battery life used to transmit. BT is a 2-way communication channel and there is some handshaking going on, but streaming music is an extremely 1-way example of a radio link.

My old portable am/fm radio would get 15 hours on a set of batteries. Why does the commercial radio broadcaster need 50,000 watts for their end of the link. Shouldn't their transmitter get the same run time off the same batteries.

I think I was about 6 when I built a wireless radio receiver that would drive an earphone with no power source at all. I could actually tune radio stations and listen to them and there was enough power in the radio wave itself to power my whole radio. That's called a crystal radio.

The pont is, it takes many, many times as much power to transmit a radio signal than to receive. And then don't forget that the BT antenna is omni-directional. It needs to transmit enough power for the receive to be anywhere in the room, so the vast majority of its power is just wasted.

I was using a simple example to relate to most readers here. If you want details, here's a spec sheet on a BT module I used in an Arduino project. On the Specifications tab it lists current consumption when powered by 3V through a DC/DC converter. The important number to look at is the current consumption peaks for active transmission vs power level. This particular chip uses 11mA for 0dBm output. Now please explain to me how BT that's in transmit mode is going to kill my iPhone battery when BT LE modules can transmit using only 11mA of current.

You can search the spec sheets for numerous BT LE solutions but you're only going to be disappointed to find how little current they take. Some units that transmit more power (say 6 dBm) can use 26mA of current. Still not significant enough to drain your battery.

Keeping it in flight mode in a cupboard doesn't exactly count as real world usage now does it.

Care to post a snapshot of your battery stats?

I will at the end of today. Yesterday I had my iPhone connected to my car for music using my Lightning cable, which will charge your iPhone. This shows up in the battery usage stats. So people don't accuse me of cheating, I'm not going to connect my iPhone to anything all day and will post my one day usage stats. I apologize in advance for destroying your lame "flight mode in cupboard" garbage. No wait, I don't. I'll let facts speak for themselves.

I find it telling that none of the people claiming poor battery life have posted up their battery stats yet. That speaks VOLUMES to me right there. Come on, where's all your proof about your battery draining so quickly you need to charge more than once a day?
 
The Galaxy Note 7 is "rumored" to have a 4,000 mAh battery. It probably will come in on the high end of 3,000 mAh, but still that is nuts. I know the iPhone is way more efficient than Android phones at maximizing the battery with their software. But I cannot imagine how awesome an iPhone with a 3,500 mAh or more battery would be? The phone is thin enough as it is so I, and many others, would be happier with a thicker phone and bigger battery.
 
Wait, did you just post a graph with units of milliamp hour per diagonal inch?
No, mAh per square inch or rather the mAh/sq.inch for phone X over the mAh/sq.inch for the iPhone 6 to see how the phones do relatively to each other.
 
Why is it so hard for apple to release an optional thicker iphone with more battery life? Are they afraid, that people will buy it more and they were wrong all along?

Looking at independent battery life tests, how many Android phones have a battery life that is, eg, 1.5x or 2x that of the iPhone? And what percentage of Android users buy those 2x battery life phones? If the vast majority of users wanted such a 2x battery life phones, we would see the corresponding sales numbers and Android phones offerings.

Let's say Apple offered a version of its iPhone with 2x the battery capacity that was 50% thicker and heavier, what percentage of iPhone users do you think would opt for it?

They do, it's called the Smart Battery Case. Hey, the vast majority of iPhone users use some sort of case anyway...

You mean like the 5.5" iPhone being more popular than the 4.7" one?

The funny thing is that those Android phones that last a long time do it by massively throttling the frame rate so the game is unusable anyway, bravo there hey,

2 things sir, 1, dial down the attitude. And 2, no one on here ever goes on about the iPhone battery being stellar, and when we have a young man like yourself come on and claim 2 full days we are all going to question the validity of such a claim. It is possible if the device is not being used. But it's real world situations that mean something,
 
Sweet, now I'll only need to charge my phone twice a day instead of 3 times.

But really, there's some pretty small battery cases these days. Since I'm on the yearly upgrade plan, I'm getting one as soon as there is one available for the new phone. I'm sick and tired of needing to be plugged in so often.

If you need to plug it in so much, there is no phone right now that will suit you and you are a special case.

Nothing like a blanket statement there fella, care to give us some examples and proof of such shenanigans.. or is it just the usual MR way of rubbishing anything that is decent that isn't apple?

With regards anandtech, that still the chap who works for Apple?
 
The S7 has a 3000mAh because it's Power Management and efficiency are terrible.

I wonder if this has anything to do with Android. I use an iPhone and iPad, but I run a Windows laptop. I'm always amazed at the superior battery life Apple get's from its laptops, so I have always assumed Apple has done a great job with power management in MacOS compared to what Microsoft has done with Windows.

So I wonder if Apple has also done a great job with power management in IOS compared to Android.
