iphone 8 vs 7 battery life?

[TorontoSS]

For those of you who upgraded from an iPhone 7, do you note differences in battery life or is it the same?

Would be great to know! My iPhone 7 battery life is atrocious. Would be good to know if there’s a difference!

Apple says its about the same in specs but the guardian review says its significantly better. Is this because the used a year old phone? It noted that an hour long commute used 25 percent of the battery compared to 10 on the 8. 25 gets used in mine too.

Coconut battery says my phone has 417 cycles, I’ve had it since last October. Seems like too much to me, but it’s because of all the draining. It’s at 92 percent capacity but still.

Would be great to know as I’ll consider upgrading to the 8!

My experience coming to the 8 from the 7 is the battery is significantly better. It seems to be lasting ~2 hours longer than my 7 did. I think this may have more to do with iOS 11 than anything else though. The battery life on my 7 absolutely tanked when I upgraded to the iOS 11 betas and never recovered. Apple says the battery life on the two phones should be about the same and teardowns of the 8 show the battery to be slightly smaller than on the 7. So I’m wondering if there is a bug in iOS 11 affecting the battery life on the 7 that might be fixed in the future.

My thought is, if battery life were so great, it would be one of the first things advertised by Apple. Instead, they claim the battery life is about the same as iPhone 7.

In most cases, battery aging is to blame. Rarely do reviewers visit Apple to replace the battery on their iPhone 7 before benchmarking.

If you look at the 8, the performance is slower and the display has been measured to be dimmer than the 7. If the battery life were so good, I can't think of why Apple would do this except to improve battery life.

 

[Technarchy]

About the same. Can't say I feel like there is a huge difference.

I need about another week with the my 8+ to get a good feel for battery life.

 

[Pelea]

I’ve had both the7 and the 8. The 8 is around 5% worse after using it for over a week compared to a new 7. Stand-by battery life has gone down significantly too, it’s a real shame .

Trust me, don’t upgrade from a 7 to an 8, the only noticeable difference is true tone.

That’s why they didn’t mention weight, thickness, storage or battery life, as all have gotten worse/more expensive

 

[Strelok]

They actually did mention battery life, it's the same as the iPhone 7/7 Plus.

It’s not the same, it’s “about the same”. Big difference in the meaning

 

[TorontoSS]

Thank you all for your replies it’s very helpful. I went to Apple today and they actually switched my phone. I have a new 7 basically today. Well the battery is new, this is what I cared about.

You’re right I think battery aging is a big deal. When you go on apples comparison page, the battery hours are the same (talk time etc). I think a year old iPhone will obviously perform much worse.

Thanks for your wise words, won’t be upgrading!

 

[TorontoSS]

Just an update, on my old iphone 7 (from day before yesterday), if I left my phone overnight without charging from 100%, I woke up with it at 83%. With the new iphone 7, I did the same and woke up to 98%. Now I did set up from new, but some of it had to do with aging. It appears a new iphone 7 battery is pretty good!

With all due respect, these sort of comments are just plain stupid and biased. The sentence I've made bold just confirms that. Yes, the iPhone 8 is not the biggest upgrade ever. In fact, it might be one of the smallest upgrades ever for an iPhone. But there's more than just True Tone. Let me list everything for you:

• New glass back
• True Tone display
• Improved main camera (just not in terms of 'specs on paper')
• 4K video at 60 FPS
• 1080p slo-mo at 240 FPS
• Slow Sync for Quad-LED True Tone flash
• Faster processor w/ Neural Engine
• Faster GPU
• 25% louder stereo speakers
• Wireless charging
• Galileo and QZSS (in addition to GPS and GLONASS)
  
• Support for Dolby Vision and HDR10 content
  
• Fast charging capable
• Bluetooth 5.0

I mean, not everything may mean something to you (e.g. Bluetooth 5.0, support for Dolby Vision and HDR10 content etc.), but it's definitely more than just 'True Tone'.

As for the battery life: this really differs from person to person. One person might have the worst battery life ever (please get that battery replaced instead of complaining about how bad it is), while the other could have the best battery life ever. Just saying.

I think the comments were just helpful, from one person coming from an iphone 7 to an iphone 8. True tone seems to be the only noticeable difference to this particular person. That doesn't make it wrong or stupid. The person may not have a wireless charger or take many photos. By the way, nor do I. I also don't walk around blaring my speakers on my phone wishing it was 25% louder. You're in a forum of Apple users, they will all have opinions on how they use their device. I asked about battery improvements, and people helpfully responded (thank you all). Some felt there was a huge increase, some felt none at all. None of these answers were wrong or stupid.

No battery life doesn’t differ from one person to another, battery life differs based on a person’s usage, and with the 8 having a 10% smaller battery, it shouldn’t be a surprise that battery life on an 8 is slightly worse than the 7

Well, to me it felt like Pelea is trying to make users actually not to upgrade based on a baseless argument. Saying that 'the only noticeable difference is true tone' does not help anyone, believe me. If I'd were to have any doubts on whether I should upgrade, I would ignore these kinds of comments and instead ask for something more nuanced. That is my opinion of course. But again, his comment does not help anyone, that's why I'm making a point of it.

Yet I am reading here at Macrumors that some are actually getting much better battery life on their iPhone 8/8 Plus. Let's not forget there's all kinds of factors to include when speaking of battery life. The much more energy efficient processor might easily be the most important factor.

Don't get me wrong, you're not totally incorrect or anything. But it's not like battery life is determined by the battery capacity alone.

people who say on the forums "this feels so much better (than my 1 year old device)" don't really have much credit to their claim. i compared a 2 month old iphone 7 to an 8 doing the same tasks and found the 8 to lose battery slightly faster than the 7.

That might've been your experience, but that does not apply to everyone.

And as for the "this feels so much better (than my 1 year old device)" thingy: same thing. This might be the case for some people, but not for everyone. I personally think the camera alone makes it a worthy upgrade, performance-wise though... not so much (but that's simply because iPhone 7 was already an incredibly powerful device). And I come from an iPhone 7.

I get it that some people don't think of it as a worthy upgrade at all, believe me I do. But in my experience, it actually was worth the upgrade. Do have to say I made the upgrade from iPhone 7 to 8 Plus, which adds some features from the iPhone 7 Plus as well.

I am just going to leave this here. My work phone is an iPhone 8. I let it sit all weekend after a full charge to just see what would happen to it.

It WAS NOT in low power mode. Bonkers to me.

Seems the draw is higher than I would expect.

A typical 8 hour overnight discharge is usually 2-5%. For a 48 hour weekend, I would expect 30% at most.

There's also over 2 hours of usage that's part of that.

Agree so much! If the 8, 8+, or X isn't for you that's fine. Keep what you have or move on to another brand. But to try and make everything bigger than what it is to make the phones look worse.... Just sad.

I was honestly surprised at the draw that RoboKiller had. It is a great app but I do have some questions in regards to the power usage. It blocked two calls over the weekend...that’s it.

25% of the 33% of battery used was solely from RoboKiller. Without that app installed the battery life would have been at 92%, which would have been even more shocking to me.

Also true.

So your saying your 8+ is Better than the 7, therefore the 8 is better than the 7.

Hello?

Hello?

I'm saying that anyone may have a difference experience. And yes, I'd say that the iPhone 8 is still better than the iPhone 7. You may or may not like me saying this, but it is factually true when you actually compare the specs of the two side-by-side. If you think of it as a very dull upgrade, that's your call. But again, factually it's still a decent upgrade. New CPU, better camera, True Tone display, wireless charging, new glass back etc. In fact, except for Portrait lighting literally everything new in the iPhone 8 Plus also applies to the iPhone 8.

Please do not attempt to drag this discussion on. Again, you can have your personal preference, not gonna argue with that. However, technically and factually, the iPhone 8 is better than the iPhone 7.

 

[nilk]

It's very likely going to be subjective, as different tasks will have different usage characteristics. 8's A11 CPU is supposedly more efficient, so a CPU-heavy task may consume less battery and complete faster. But the 8 has a smaller battery, and it's unlikely everything it does is going to be more power-efficient.

You can see how things can go either direction looking at two different benchmarks. Anandtech's wifi browsing test showed 7 doing better than both the 8 and 6S:

Whereas Phonearena saw the 8 doing better, but I don't know what their testing methods are:

One sec, you’ve never actually used a regular 8 have u?

Are we not talking about specifically the battery usage here?
