It's Not Your Imagination: Smartphone Battery Life Is Getting Worse (washingtonpost.com) 160

An anonymous reader quotes a report from The Washington Post: For the last few weeks, I've been performing the same battery test over and over again on 13 phones. With a few notable exceptions, this year's top models underperformed last year's. The new iPhone XS died 21 minutes earlier than last year's iPhone X. Google's Pixel 3 lasted nearly an hour and a half less than its Pixel 2. Phone makers tout all sorts of tricks to boost battery life, including more-efficient processors, low-power modes and artificial intelligence to manage app drain. Yet my results, and tests by other reviewers I spoke with, reveal an open secret in the industry: the lithium-ion batteries in smartphones are hitting an inflection point where they simply can't keep up.

"Batteries improve at a very slow pace, about 5 percent per year," says Nadim Maluf, the CEO of a Silicon Valley firm called Qnovo that helps optimize batteries. "But phone power consumption is growing up faster than 5 percent." Blame it on the demands of high-resolution screens, more complicated apps and, most of all, our seeming inability to put the darn phone down. Lithium-ion batteries, for all their rechargeable wonder, also have some physical limitations, including capacity that declines over time -- and the risk of explosion if they're damaged or improperly disposed. And the phone power situation is likely about to get worse. New ultrafast wireless technology called 5G, coming to the U.S. neighborhoods soon, will make even greater demands on our beleaguered batteries.
If you want a smartphone that excels in battery life, you pretty much have two options: Samsung's Galaxy Note 9 and Apple's iPhone XR. According to The Washington Post's tests, the iPhone XR and Note 9 topped the list with times of 12:25 and 12:00, respectively.

    All that has to happen is that smartphone makers (Apple I'm looking at you) need to stop the obsession with making every device thinner than the last one and add a bigger battery pack or make a decent interface for a battery case that doesn't involve a clumsy and bulky pass through of the USB port.

    There are a lot of us (myself included) who wouldn't mind a modestly thicker device in exchange for a bigger battery, better camera, etc. I'm going to put a case on anyway so why not facilitate putting some real utility into the case while we are at it? In an elegant way rather than the clumsy hacks we've seen to date. It would be trivial to allow people to add the audio jacks to the case for those who want one while permitting those who don't care to add something else. As big as the market is currently for smartphone accessories I think it could be a LOT bigger than it currently is if Apple and others would get their head out of their designers asses and look at how people actually use these things.

      Why do we even need a separate case? All those super thin phones are pointless if you need to put them into a bulky case to protect them. Make the phones themselves thougher and case-like protection, add a bigger battery and camera, and you'll have a far better device that's not any bigger than a thin phone in a case.

        Why do we even need a separate case? All those super thin phones are pointless if you need to put them into a bulky case to protect them.

        The modularity of the cases has actual utility. It's cheap to replace a damaged or worn case. Plus it provides an opportunity for people to personalize their device both aesthetically and functionally. The problem is that Apple and others have ignored the function component of cases. It's a huge missed opportunity.

        And some people like the thin phones and some don't bother with a case. So by making cases as functional as possible you increase utility to the largest quantity of smartphone users with the fewest trade-offs. Speaking for myself I'd like a case with a bigger battery and better camera optics. Other people would probably like a 3.5mm audio jack or a SD card slot. By making a way for the case to provide this functionality people can get the device they want and Apple/Samsung/etc can focus on making the core device as tight as they like.

        • by mcvos ( 645701 )

          Well, with my Fairphone 2, the body itself is modular. If it gets damaged, I can replace the body while keeping the rest of the phone. Having the body and the case as two separate things is useless.

          I'm fine with some smartphones being super thin, fragile and having no battery life if that's what some people want, but I'd like there to also be phones that are more sturdy and have better battery life. Buying a separate case that adds bulk without adding battery life is a wasted opportunity.

          Consumer reports did the same sort of tests and reports the opposite finding at least on the iphone X series.

          What did they do differently? well consumer reports uses a robotic finger to run the test suite the same way that a human finger would. The Washington pose it appears used programatic control to drive the phone.

          It appears that perhaps the User interface engineers have discovered how to let the phone rest between finger taps or to anticipate what finger taps follow others such that it actually improves power efficiencny.

          Now as for your comment about case modularity. Well it's a nice thought and the argument makes sense down to the point where it defeats the overall objective. Here things have scaled down to the point where the case is taking up a significant portion of the volume. Having two cases is nuts when you could have a bigger battery in the same volume.

          One could imagine having a replaceable cover on a phone without a structural inner case.

            There are several problems with your argument. Here are just a few: 1) None of the smartphone makers are going to change from the current case paradigm for a variety of reasons. 2) There is utility in a second casing since the device remains useful without the outer case. This allows multiple cases for different purposes. 3) Obviously people are fine with adding secondary cases. 4) User applied cases are going to have substantial problems with water and dust proofing.

                judging by sales you are in a vanishingly small minority. Please note I'm not being critical of your choice of device, just observing the reality that most people demonstrably have approximately zero interest in repairing their own device or digging around in the guts of them or dealing with the tradeoffs involved.

      2. Return to having a user replaceable battery that can be replaced in a few seconds by popping the rear panel off, taking the empty battery out, putting a full one in and closing the rear panel. As essentially all phones in 1990s allowed you to do.

    None of the non-mainstream phones have a battery life problem. You get phones with 10Ah from a load of manufacturers now.
    The "problem" is, that you can't cut your wrist with them because they're not thin like a knife for no freaking reason, and you can't hold them like a boom box because they're so impractically oversized. They may weigh a bit, but that's because they got actual batteries in them. And actual tough cases, if you want.

        Yeah, really [xda-developers.com]. And that's why Android OS occupies close to or even more than 1,5GB of RAM in modern Android releases?

        to emit more light

        More light? How so? The screens have become a lot more power efficient recently.

        with ridiculous pixel densities

        Yeah, exactly, except my five years old Nexus 5 has a FHD 5" screen and modern phones have basically the same resolution for 6-6.5" screens, so if anything the pixel density has increased.

        doze and app standby are specifically there to reduce wakeups

        Except Pie is worse [slashdot.org] for your battery than Oreo before it. Maybe next time research a little bit more before spewing out BS.

        Android has become a complete resource hog recently and Google even released a special version of it (Android Go) which could fit in 1GB RAM smartphones. I vividly remember previous Android releases had no troubles fitting in such low-memory devices and being able to even run apps. Wow. Nowadays people with 4GB of RAM complain that Android kills apps when there are no (visible) background apps running.

          Argh. "power management". I meant power management.

          Maybe next time research a little bit more before spewing out BS.

          Oh, you're an arsehole! You didn't have to be, you could be civilised, but no. I'm not 100% agreeing with you, so you immediately resort to insults. How disappointing.

          • A correction, I meant "the pixel density has decreased". As for "insults" - IMO, I didn't say anything offensive. If you believe I did, I apologize. Cheers!
  • Does increasing the resolution of the screens increase the battery usage? I ask because manufacturers keep increasing resolutions completely pointlessly, and if it comes at the expense of battery life I want them to stop.

    Trying to think this through: It would use more RAM, and more CPU to update the screen. On the other hand, the biggest battery drain is probably the backlight which remains the same. In the case of OLED, the pixels themselves product light, but it's the same overall luminance and surface

      When Apple released their iPad with retina display I read that the additional pixels require more electronics in the display which block some of the light. This in turn means that a stronger backlight is needed to have the same light output compared to a lower resolution display. For LCD it was an important factor at that time. For OLED, this might not make that much of a difference unless some of the connections would be on top of the pixels or due to a minimum border size per pixel.

    Why do you have to choose from these overpriced phones? There are plenty sub 200 dollar phones with 3000-400mAh batteries.

      Suggestions?

  • How about making a phone with an easily replacable battery so you can carry a spare? That way you can watch it as long as your eyes can stand it.

      Then, companies will lose money for people who keep using their old phones. [grin]

  • Want long battery life and rocket-fast internet? Turn Javascript off. Yeah you can't interact with the social-media spyware plugins or comment (or read mobile slashdot) anymore, but unless one needs a piece of web outside W3C, Javascript not worth it at this point. Megabytes of analytics and useless videos wrapped in code that loops phone into a heater half the time...just from trying to read an article on CNN. Add it all up and its like tenth of the degree that will kill us all by 2050 or whatever, and th
  • For years it's been a given that this year's computers have more available resources than last year's. This goes for processor speed, RAM, storage, GPU speed.
    So the usual MO for many has been to use those extra resources to the fullest extent, leaving only a small gain in functional speed for the consumer to notice.
    Apparently it hasn't fully sunk in yet that battery capacity (like pretty much everything else in life) does not conform to Moore's Law and that including the kitchen sink software-wise is going

  • Big batteries are one of the best features of a cellphone.

    Get rid of the curved screens, too! I already broke 2 screen protectors on my Galaxy Note 8. I liked the Galaxy Note 4 Better.
  • If smartphones used native apps rather than simulated computers, they'd probably retain power for longer.

    Removing autoincorrect might help.

  • Still using my Samey S5. It still has the original battery.
  • I did...my last 3 phones have had 4,000mAH batteries, and were great!

      Which ones?

  • Battery technology should be making a leap pretty soon. But I'm not familiar with the time scales of these sorts of advancements: https://www.futurity.org/ceram... [futurity.org]

    Hopefully the technology will become available in consumer devices at a point when it still has the power to impress us with a charge that can last a few days.
