    The so-called "iPhone 8" will adopt a higher-cost stacked logic board design to support longer battery life, according to KGI Securities analyst Ming-Chi Kuo.


    Kuo said the stacked logic board, also known as a "substrate-like PCB mainboard," will result in the "iPhone 8" with an OLED display having similar dimensions to a 4.7-inch iPhone, yet comparable battery life to a 5.5-inch iPhone. He expects the device to have around a 2,700 mAh L-shaped two-cell battery pack.
    Kuo added that the battery life of "iPhone 8" with an OLED display could be better than that of a 5.5" model with a traditional LCD display, as OLED panels are more energy-efficient than their LCD counterparts. For comparison, the iPhone 7 has a 1,960 mAh battery and the iPhone 7 Plus has a 2,900 mAh battery.

    This is good news but in the future they should focus on emerging battery technologies, rather than trying to fit as much battery as possible into the design.

    That "3-5 years" period will remain the same if large companies don't invest in some of the new battery technologies.

    The iPhone 8 rumours are on fire today!

    I still can't believe we'll get 3 iPhones in one year.

    That's really good, but couldn't they also make the phone 1mm thicker?

    Guys, get ready. This is going to be expensive.

    I don't care about price. I want the iPhone to continue to be very the best smartphone money can buy, and I'm willing to pay any price to ensure it remains at number one. Price considerations should never hold back innovation.

    Bigger battery would be nice but new design is still a must.

    Smart to focus here - Improved battery life is on on a short list of improvements that appeals to almost everyone. (Everyone?)

    It's good that they're increasing the battery life, obviously. But increasing the battery size results in a heavier phone and longer charging times (although that'll be fixed with fast charging).
    There are some batteries out there that can charge in minutes, that don't explode, and that have a greater density. I don't think stuffing more lithium ion battery into the casing is a better solution, but it doesn't mean that it's not a good thing.

    Like I've been saying, they will fit a 5.8" bezel-less screen on a footprint roughly the size of the iPhone 7. Amazing!

    I feel like battery technology will just never be amazing on the iPhone.

    Wow -- now that's cool. That just may be enough to get me to switch back to IOS from Android...

    I have always wondered why big companies wouldn't invest in such technology. My belief is that all the viable future battery tech is patented and it wont be cheap to purchase the license.
    Also "long-term" safety is another issue...

    Im sure there are many other holding factors that are preventing new tech to emerge.

    That also don't stand up to the charge cycle amounts that Apple/The Entire Industry needs, or can't be massed produced yet.

    We all know there are better battery technology on the way, the industry is investing like crazy in R&D. They'll get here, but it makes no sense to stand still in current tech while working on them.

    Given the demand for battery technology (electronics as well as automobiles and power grid) there are already many large companies looking for the better mouse trap. I'd say that battery tech is not one of Apple's core (see what I did there ;-) competencies, so better that they rely of existing proven technology whilst they focus on things they can control (ARM architecture, user experience, ecosystem, etc). Besides, power drain is not one of their short-comings as it stands now. Lower power parts will just help that be even better. IMO they are in a position to focus their attention elsewhere.

    I've heard the next iPhone model comes with friggin sharks with friggin lasers. It'll be a dazzling user experience.

    More area for the battery...but a thinner battery (read: thinner iPhone)!

    No complaints at all if the goal is longer batter life.

    However, does this pass the smell test? Stacked PCB seems to conflict with the paramount goal of "thinner"- if not immediately, then down the road. And "more battery" also seems to conflict with "thinner," especially if OLED will need less battery. I would think if a key battery-using component like the screen needed less battery, Apple would reduce the battery and spin "same great battery life" so they could also spin the "thinner" that just about nobody wants.

    But again, I hope this is true- more battery life is a tangible consumer benefit that likely appeals to almost anyone... unlike "thinner."

    This would be great, I can see why the iPhone 8 is going to cost more, with OLED, better battery tech, rumours of face or retina scanning and so on, it will be worth it in my opinion. I wonder if they will also add another colour option?

    It's time to move on from the current battery technology and only involve companies that are allies and are trusted.
