Is iPhone Battery Usefulness On the Decline? 222

Posted by samzenpus from the more-time-please dept.
jfruh writes "Every time a company rolls out a new version of a product, it extols how much better it is than the previous version. Thus, Apple spent a part of its iPhone 5 rollout touting the staying power of the latest version of its battery. But have iPhone batteries really seen improvement since the original came out in '07? Kevin Purdy crunches the numbers and concludes that, while the 5's battery beats the 4S's, we still haven't returned to the capabilities of the original phone."

      I think the comparison is one of Battery life not keeping up with battery usage in newer devices. Technology is not increasing at the same rate, but the expectation is still there, especially for people who previously owned earlier versions of the iPhone. What most people see is not "my iPhone battery consumption is high because of increase demand from data networks", but rather "I never had to charge my old iPhone this much." Its like comparing movies sales in 2012 dollars, its a perfectly valid statement to make, even though we all know what causes the reduced data usage.

    And as competitive as smartphones are today that's close to as good as we'll get for a bit. There IS a type of Lithium-ion battery that can store twice the charge of today's batteries at the same volume, but that's apparently coming to electric cars first; which obviously spend a lot more on batteries per unit and are in far more need of it.

    But expect these batteries in phones at some point. In the further future the most promising technology is lithium-air batteries, which offer up to 10x the current charge per volume as today. But there are still numerous problems with them, and so an ETA there would be indefinite but quite possibly less than a decade. Still, imagine a phone that would need charging less than once a week!

        Probably not. In some situations, LTE can actually use less power than 3G. Mine, for example. I got all-day-plus performance on my Galaxy Nexus (with the 2100mAhr battery) at my old office. That was in Philadelphia, in a very old stone building... very good 4G signal, in fact, much better in-building than 3G ever was (most of the cells in the city are going to use 1900MHz on Verizon, for the increased bandwidth, which gets more attenuation through old stone walls than the 700MHz used for LTE).

        These days, I'm in an office in Downingtown, PA, in a pretty fringy 3G area. Same phone won't last a work day on standby without sitting on a charger when not in use.

        Going forward, LTE will eventually save power over any form of 3G. Right now, not necessarily -- the digital protocols still take more power than either sort of 3G, but that's going to vanish as chips shrink. What you can't shrink is the need for the power amplifier (PA). Most phones want to be able to put out a signal of at least 1/2W (27dBm). The typical OFDM modulation schemes used in 3G, however, basically sum a large number of independent carriers (subcarriers) to deliver the full signal. When things line up unfortunately, you have too many signals summing high, creating a temporary power "crest".. this is known as the crest factor of a modulation scheme. For 3G as a class, this is a 6-10dB crest factor (also sometimes expressed as a PAPR -- Peak to Average Power Ratio). This means that the PA actually has to be able to support no just 27dB signals, but 37dB signals... a peak of 5W. Now, certainly, your phone isn't constantly transmitting 5W. But the PA has to be able to transmit at 5W without crushing the signal. That means the PA is going to be much less efficient than it could be at 1/2W.

        Now to LTE.. the new SC-FDMA uplink modulation, presents only a single carrier on transmission, greatly reducing the PAPR/crest factor. Basically, it's a conventional OFDM modulation fed into a fourier transform, which has the effect of averaging out the high peaks. This can deliver 64QAM with a crest factor under 5dB. So you'd need an amplifier peaking at about 1.5W, rather than 5W, for the same uplink in 4G LTE vs. 3G HSPA. That's a huge win for the handset.

      Actually, simple hydraulics and electronics have natural analogies [gsu.edu], in that similar equations can be used for both. Milliamp-hours is a unit of charge, 1 mAh == 3.6 coloumbs, or about the charge in 3.73e-05 moles worth of electrons, so yes, it would be accurate to say that mAh can be analogised to the volume of a tank of petrol, as charge would be the equivalent of fluid volume in hydraulics. However, voltage, being in units of energy per unit charge (a volt is 1 joule per coloumb), is more like fluid pressure in hydraulics (joules per cubic metre or pascals), or at how much pressure the fuel is being sent out the gas tank, so the article is completely wrong on that score. The "amount of fuel the device is drawing" is more like current, which is measured in amperes (coloumbs per second), which would be the equivalent of flow rate in hydraulics (cubic metres per second). Thus, if you had a battery rated at 1500 mAh used on a device that drew 100 mA of current from it on use, you'd be able to use it for about 15 hours before you needed to recharge the batteries. In a similar way, if you had a tank with a volume of 1500 cubic metres and were pumping liquid out at 100 cubic metres per hour, you'd need to refill it after 15 hours.

        Browsing is not watching media only. Browsing is loading pages, reading them, moving on and reading more. It's not about constant data streaming, so it's not overall something that will destroy your bandwidth - you can only read so much in eight hours!

But that is why mobile app developers are not giving you those really beefy data streams, instead over even LTE you'll get reduced quality video from most things unless you force the issue.

The article is flawed because it doesn't take this into consideration. People upgraded their phone to take advantage of the more advance features, so increased power usage should be taken into account.

      My android phone battery has a much shorter battery life when I travel to some locations. I believe its a function on how much power is required to maintain contact with the nearest tower (using "4G" doesn't help). Right now I'm on the road and I'm lucky to get 24 hours of "standby" time on a single charge (standby being in quotes due to email client running in background so data is being transmitted on occasion).

      My iPad2 seems to last a very long time (charge once a week range), but it's WiFi only and therefore doesn't need to use power to maintain contact with a tower miles away. Also the iPad2 models that have a wireless modem built in (CDMA or GSM) has the luxury of being able to put that modem to sleep to increase battery life since it doesn't have to accept incoming phone calls (especially when a WiFi connection is available). Also the iPad2 is able to have a physically larger battery.

      My point being that "Your milage may vary" due to factors like usage pattern, location in respect to cellphone towers, and the data protocol being used.

    It's an oversimplification to assume that a company would, or should work to increase battery life. The different features have to be weighed against each other. Performance comes at the expense of battery life. A larger battery would mean a heavier, bulkier phone. Lithium ion batters today have about the same capacity of the batteries which existed when the first iPhone was released, while power efficiency of electronics has increased significantly. They could have used these advances to increase battery life, but have instead chosen to use them to increase performance.

      That said, I get a week or so out of an old OG Droid that has no cell phone service. I used to have to recharge that exact same Droid every day when I used it as a cell phone, whether or not I actively used it it at all.

      I remain puzzled as to how a phone that is just a dumb phone g

        OK, who the fuck told you that? They are a lying dipshit. E911 does not require that all phones have a GPS. It only requires that the provider be able to provide positioning information. Literally all GSM providers in the USA do this with DToA, not with GPS. CDMA providers may also use DToA, but my understanding is that originally, the US CDMA providers did decide to go with GPS instead, so there's a lot of verizon and sprint phones with secret GPS receivers the user is not allowed to access.

    There is a very good car analogy here.

    Over the years cars have become much more efficient, through various refinements and improvements in the design of the internal combustion engine. We are able to produce more horsepower with less fuel. So, did cars stay the same size and increase in fuel economy over the years? Some have, but especially in the USA, designers instead chose to increase the size and power while keeping fuel efficiency relatively constant. So the engine has become more efficient, yet those gains weren't used to produce a more fuel efficient engine, they were used to make bigger, more powerful, cars that had the same fuel economy.

    With the iPhone, the battery definitely has become better of the years. So did Apple choose to increase battery life? Nope. As with the cars, they increased the CPU power, screen resolution, GPU power, memory, radios, etc. They packed more powerful components, more efficient components, into the same size with ever increasing battery technology. So battery tech has to keep improving all the time, just to keep up with the increase in power usage from the rest of the system, and it doesn't even always keep up. It takes all the running you can do just to stay in the same place.

    I've not developed this very far and I know there are counter-examples, many came to mind while writing this, yet the analogy is apt especially when we confine our comparison to specific segments of the US car market. I'm pleased that, in recent years, this trend seems to finally be reversing, and the US is becoming more--if only slightly--like Europe with their focus on smaller, more efficient cars.

      They packed more powerful components, more efficient components, into the same size with ever increasing battery technology.

      The iPhone 5 is 1.778 mm thinner than the previous iPhone.
      That's almost the difference between the Droid Razr and the Droid Razr Maxx.

      You know what the Razr Maxx did with that extra thickness?
      They almost doubled the battery capacity and now have a phone that outlasts everything else.

      But people are used to plugging in their smart phones to charge every night, so Apple doesn't lose anything by adding thinness instead of battery life.

      • I'd prefer to pick the size of my battery than have it dictated by the design of the phone. Back in the day, I had three batteries for my old Nokia. The stock battery that I never used but kept charged as a spare, a very thin/light battery for day-to-day use that I charged each night, and a gigantic brick of a battery that could go for a week between charges which I used when travelling. That was normal back in the analog days and I wish manufacturers would bring it back.

    To smartphone making companies: Stop using the advancements in manufacturing to make the phones slimmer, they're slim enough (I'd say too much), instead use it to put larger batteries. They really need them.
    I know some companies have gone that route (some Motorolas have large batteries) but we need more of these.

      Yep, I agree, it appears that they make the phone as small as possible, then get a custom battery to fit in the gaps. Some phone company should grow a pair of balls and design a phone around targets for what the battery should be able to do. So far it has only been the motorla razr maxx, and i would have bought it if not for my awful experience with android fragmentation and bugginess.
