Battery Life - A Magnitude Shift

By now many will have heard positive things about the new iPhone 11s' battery life. As we have covered in the introduction, possibly the biggest changes to Apple’s line-up this year is the device’s vastly increased battery capacities. The Pro models in particular have seen significant increases: the 11 Pro gets a 3046mAh battery which represents a 14.5% increase compared to the XS, and the 11 Pro Max gets a 3969mAh battery which represents a very large 25% increase. The Pro Max is now the first Apple device which has a battery capacity comparable to Android phones out there, some of which have offered similar large capacities for a few years now.

The regular iPhone 11 sees only a 5.7% bump to up to 3110mAh, which isn’t all that big upgrade compared to the XR. But it also doesn’t increase its weight nearly as much as the Pro models.

The battery results in our web test are outstanding. Apple in this generation has gone from being average in battery life to showcasing some of the best results we’ve seen in the market.

What is very interesting here is how our absolute test runtimes end up compared to Apple’s marketing claims. Apple has promised +1H, +4H and +5H of battery life for the 11, 11 Pro and the 11 Pro Max compared to their predecessors, and what we measured is 1.08H, 3.9H and 5.27H, which is pretty damn near Apple’s promoted figures, pointing out to some very similar testing conditions between our test and Apple’s internal metrics.

If we break this down a bit and theorize a bit, if we take the XS Max 10.31H result, multiply by 1.25x for the increased battery capacity (12.88H), multiply again naively by 1.15x for the more efficient screen (14.82H), we’re left with a ~5% margin which would account for the more efficient SoC. Give or take margin of error here or there, the results we’re seeing shouldn’t be all too surprising. The math would also check out for the iPhone 11 without a newer display: 5% increased battery capacity and an on average ~3% more efficient SoC.

There’s not much to say about the new iPhone 11 series' battery life other than it's exemplary. More importantly, Apple has managed to finally catch up and exceed the battery life of the LCD iPhone 8 and Plus models from 2 years ago.

    Just get the battery replaced at authorized repair after three years or whenever it starts to go bad.

    And as you very well know, the throttling (if it kicks in) can be toggled on/off in the settings.

    I have a two year old iPhone X and the battery capacity is at 91%.

    You're asking that the phone under report it's battery reserve and shut the phone down at 40% battery to preserve battery longevity?

    Because that would be the effect. So instead of a battery that lasts 14 hours for the first year and then 10 hours the second, it would 'shut down' after 11 hours the first year, and 'shut down' after 11 hours the second year, and 'shut down' after 11 hours the third year, before the degradation actually causes the battery life to actually be 10 hours in year four.

    Wow! That makes no sense. All phones slow down over time, and all batteries hold less charge. Apple’s are t worse, if anything, they’re better. My Max, from last year still reads 100% on battery health after more than 11 months of fairly heavy daily use. I’d like to see other phones that do better. Reply

    Look at intel /AMD / Qualcomm. They list a "turbo speed" that is not guaranteed. But customers believe it is. That's why they don't need to downclock stuff because they never need to hit their speeds. Apple is the last vendor having a real CPU speed and holds it. I have had a multitude of Intel CPUs that under-deliver in speed and as a customer you can't do anything. The service centers simply don't understand the problem since they only do a CPID check and says "it works". Take any intel laptop and fire up an H265 encode and watch the CPU speed go down. A CPU labeled 2.9ghz /3.9ghz turbo suddenly is a 2ghz part and you can't do anything about it. At least with Apple: get a good battery and it works. Reply

    All for the low low price of $1300. Pass. Reply

    $999 actually.

    This is a device that you can use for five years, or more, always with the latest software. Just get the battery replaced once.

    Amazing value, as iPhones always are.

    Nice troll brother. But a full loaded iPhone 11 Pro is $1299.

    iPhones are trash.

    You can get an iPhone 11 with 128 gigs for $749, which pretty much mops the competition with battery life, CPU, GPU, longevity and value.

    I know your troll self will say something like “BR0 it’s only GoT a 720P scr33n, my 2015 GaLaXy HaS h1gher Res0lution!

    Fact is, most people don’t care about that. That’s why the XR was the most popular phone last year and that trend will continue.

    The pro starts at $999. Stop trolling. This site is for adults only. If you only post your lame hate comments, please go to YouTube. There’s plenty of room for your kind there.

    Shoo shoo now.

    This analysis is great but the Whiteknighting is insane.

    The design the primary aspect of a device, the display itself is notched no matter what calibration it has it's destroying the proper nature of how we perceive through our eyes and mind. Dead pixel zone for $999

    No expandable storage, No Filesystem access - Must use iTunes. This means for every basic work you must rely on your computer and the iCloud, mega ecosystem lockdown.

    No 3.5mm jack. Its really a shame how this company made billions by buying up Beats (Sub par garbage audio) and AirPods ($179 of Sub 320kbps audio with limited life due to Li Ion) and making a dongle business out of an Analog standard and whole industry reeks of this greed by dongles snd their own BT products which are massively inferior in sound snd usage and also wear down the only port it has.

    Sealed battery, Strong adhesive with new 4m depth rating. $600 for back glass repair if no Apple care and they are forcing you to buy because its $300 only and 70USD per repair. More profit for Apple for $100 battery services. Unfortunate that Apple has brick and mortar rest do not but they want to siphon off. Also did author note how iPhone XS got the new battery throttling with latest iOS update ? Yeah bonus package to wreck all that performance, inherent overdrawing of Voltage and planned obsolescence.

    Too much of this price hike and offering measly 64GB base. Next year another $50-100 due to new design or whatever they want to call.

    Desktop performance. I want to see, can this A series chip run an Adobe CS6 or Blender or do a H264 Conversion faster or on par with a desktop chip ? Or play high refresh rate gaming or can it execute x86 instructions with ease and replace my PC with this BGA pile of junk ? (It cannot, I think it's too much of blowing into this hot balloon of Apple for mega limelight) same for 9900K or 3950X they can't be fit in a pocket.

    Finally the corporation of American back, has no backbone when it comes to China. The $$$$ speaks. Censorship and aiding the Orwellian draconian principles for cash is more than the American culture that spawned the company and its people. A big shame.
