Our iPhone 8 Plus battery life test reveals the best endurance from an iPhone yet

With more people lining up to buy the iPhone 8 Plus than the smaller iPhone 8 for the first time (perhaps in anticipation of the iPhone X), the focus has suddenly shifted to Apple's larger phone that is more feature-rich, thanks to the dual-camera setup on the back, but also lasting much more on a charge, thanks to the bigger battery. Not only does the iPhone 8 Plus endure 25% further on a charge than the iPhone 8, but our battery benchmark test reveals that it is way ahead of the iPhone 7 Plus, too, and, in fact, the 8 Plus is the longest-lasting iPhone we've ever tested.

This is undoubtedly due in part to Apple's new Bionic chipset that is not only extremely powerful, but also built on the frugal 10nm processor node that sips electrons while performing mundane tasks, but revs up when needed for heavy games or AR calculations, for instance. Given that the screen resolution, RAM amount, and software are the same on the 8 Plus and 7 Plus, the gain in battery endurance can mainly be attributed to the processing power management, moreso having in mind that the 8 Plus also comes with slightly smaller battery capacity than its predecessor.

How does it compare to Android flagships? Well, the ones that are with QuadHD or QuadHD+ screen resolutions are no match for the 1080p iPhone 8 Plus, as you can see below, with the slight exception called HTC U11 (seriously, HTC manages to squeeze some record juice out of its 3000mAh pack), and, since there aren't many other "Full HD flagships," save for the Xiaomi Mi 6, the iPhone climbs to the top of the pile. Given how well iOS 11 manages standby draw, you can expect a day and a half to two day battery life with the iPhone 8 Plus, depending on your usage, which can't be said for the vast majority of expensive phones these days.

Battery life (hours) Higher is better
Apple iPhone 8 Plus 10h 35 min (Excellent)
Apple iPhone 8 8h 37 min (Excellent)
Apple iPhone 7 7h 46 min (Good)
Samsung Galaxy S8 8h 22 min (Excellent)
LG G6 6h 9 min (Average)
Apple iPhone 6s 8h 15 min (Excellent)
Samsung Galaxy Note 8 7h 50 min (Good)
Xiaomi Mi 6 9h 14 min (Excellent)
LG V30 9h 34 min (Excellent)
HTC U11 9h 3 min (Excellent)
Google Pixel 7h 45 min (Good)
As to charging times, well, the iPhone 8 Plus has fast and wireless charging standards built in at long last. Fast chargers would top up your 8 Plus 50% in half an hour, but they, and the respective cable, don't ship in the box, so you'd have to splurge some extra dollars to buy the kit from Apple, or go half price, but with third-party fast charging solutions. Otherwise you will be stuck with this:

Charging time (minutes) Lower is better
Apple iPhone 8 Plus 178
Apple iPhone 8 148
Apple iPhone 7 141
Samsung Galaxy S8 100
LG G6 97
Apple iPhone 6s 150
Samsung Galaxy Note 8 102
Xiaomi Mi 6 114
LG V30 108
HTC U11 98
Google Pixel 119

GSMArena says otherwise vs the Note 8. Note 8 lasts more than the iPhone 8+.

PA has it's own way to measure things related to Apple products. The script used got a default parameter "BestProduct" set on "Apple". Most likely they always forget to overwrite the default settings.

Because it simply is the best product.

I know you can't afford an iPhone so

yes.. that's why I bought a note 8! Plus, if affordability is a criteria for you when you purchase a device, says allot of things about what "features" you are using most. :))

I see you saved few hundred bucks there. Around 400 in my country. Good job.

Sure, and he (gigicoaste) lives in your country as well, right? In the US, the iPhone 8 plus is cheaper than note 8 by $140-180 cheaper.

Everyone can afford an Iphone if they want too...... they just choose not to be a simpleton.

How is that an argument. How do you know what he can afford? With carriers doing monthly payments, who can afford $35 per month on a phone? I think i you have to resort to making claims you can't even prove, then you already are a pathetic loser. You have no way of knowing what people can afford. Even if what you said was true, it still isn't an argument. I can afford a BMW i8. Can you? The fact that you can't is somehow and argument?

define best!? I mean.. again and again.. Apple cannot be compared with devices with different OS!! To me, IOS is dumb, not enough productive and flexibility offered, so, TO ME, Apple products are far to be the best, are average on max. Apple has is own eco-system, that is dumb nowadays, IMO!

That is why I use adblocker plus on PC and Adguard on my phone, so these idiots won't get a cent from me by mistake.

as a matter of fact I always have the adblocker turned off on fair and objective tech websites.. such as gsmarena..

That's what I just did and my phone does not lag anymore on this damn site!! I thought it was my V20 all this time.lol

PA's battery life test focus mostly on CPU work loads, In other words it heavily favors the iPhone. Anandtech hasn't reviewed any of the new iPhones but they do the most extensive and reliable battery life test as well as cpu and gpu, their reviews take a while to come out because of their thorough testing but are definitely worth it.

Take a while? That's an understatement. They used to have much quicker turnaround. I don't know what's going on over there.

A while is putting it lightly compared to how much faster they use to be and even then they have always been slower than other sites, idk what happened to them either.

PA's battery test is messed up for Android phones According to their test: Both the S8+ (3500 mAh, 6.2") and Note8 (3300 mAh, 6.3") has less battery life than the S8 (3000 mAh, 5.8") The Pixel XL (3450 mAh, 5.5") has less battery life than the Pixel (2770 mAh, 5") The Nexus 6P (3450 mAh, 5.7" AMOELD) has less battery life than the Nexus 5X (2700 mAh, 5.2" IPS) The Honor 8 Pro (4000 mAh, 5.7") has less battery life than the Honor 8 (3000 mAh, 5.2") All of these larger phones have more battery life in real world usage and most other tests from e.g. GSMArena and AnandTech

I want to see PA's tests on how they test. A "test" and real world usage are simply not the same. Online "real world tests" shows the iPhone playing games for 2 hours, Web browsing for 2 hours and watching video for 2 hours and they all lost in each test. The phone dying in less than 6 hours. Also when doing the math, there is no way the iPhone doing tasks will last more than 6 hours on 27xxMaH

Yeah, but for same GSMArena shows that Web Browsing and Video Playback is higher on iPhone, it's only Talktime that Note 8 wins on. So the question now becomes: Do you use your phone to make calls primarily or serf the web and watch movies? I actually use my phone for web and entertainment so much more than actually making phone calls (and even 95% of my calls are brief). My biggest drain are intense graphics 3d games: RR3 and Afterpulse and Google Play only has one of them - so for me iPhone wins here as well.

Battery test for phone calls is pointless. Who even use them these days? iPhone 8 Plus has a way better battery life than Note 8.

:)) Those which are buying a smartphone for the primary functionality.. which obvious is .. making phone calls!! Are still people out there which are not buying phones just to play games or have music loud on it (therefore the need of stereo speakers with 1000000 w). As Xilam said, for what he is using Iphone 8 is what he needs... I guess for you is only important a debate.. as it can be easily seen.

The iPhone 8 Or the X when it comes out will beat any new android phone out to date. I don't care that u can read iphone paper stats. This is the real world. U get that. And real world test the iPhone battery is not better. I have. Ever met a person with a iphone that didnt carry around a damn charger. U can check any YouTube video comparing both. IPhone battery is not good when it comes to playing videos. Any kid of video playing with drain. Ur battery to s**t.

That's odd. Not a single call placed here. https://youtu.be/e-691mHL1to Or here... https://youtu.be/IbSjUq_kvSM

Idk but these battery tests seems flawed to me...Like in one of XEETECHCARE videos Note 8 beat S8+ while in the other S8+ beat Note 8.

Most of reviews and battery test in internet said otherwise.. iPhone8+ cant even beat S8+

I will await the more extensive testing from Anandtech and PocketNow before I come to my own conclusion. Besides, Android still suffers from wakelock issues, many of which are stemming from Google Play Services or Android OS (which has all these tasks listed underneath) and these issues just crop up randomly. The forums are full of people experiencing such problems with many of them saying that their battery life was fine until they updated the phone through OTA or updated any of the Google services. Will Oreo clamp down on background tasks from running amok? Time will tell but Google' made the same promises before when it came to Nougat, Marshmallow and JellyBean.
