Apple Working With Consumer Reports on MacBook Pro's Battery Issue (cnet.com) 254

Posted by msmash from the sorting-things-out dept.
Last week, Consumer Reports concluded that it won't be recommending Apple's new MacBook Pro models. The American magazine published since 1936 by Consumers Union, a nonprofit organization, cited inconsistent battery issues for not recommending the MacBook Pro for the first time in its history. Apple's VP of Marketing has since addressed the report, saying they are working with the magazine to understand the results. From a report: Apple Senior Vice President Phil Schiller followed up with a tweet late Friday saying Apple is "working with CR to understand their battery tests. Results do not match our extensive lab tests or field data." Consumer Reports' review says that in-house testing revealed wild fluctuations in battery life for unplugged MacBook Pro computers. In the case of the 13-inch model without a Touch Bar, for example, battery life ranged from 19.5 hours to just 4.5 hours. Apple says the devices should operate for up to 10 hours between charges.

      Especially things like extremely varying battery life ranging from 4.5 hour to 19.5 hours.

        I think you are missing the point, if you think this is about "advanced and extensive" testing.

        I don't expect the Consumer Reports' crew to be experts on this sort of thing. I expect they will run things more along the lines of how a typical non-technical Mac user will run things, because CR's team probably isn't that much more knowledgeable about Macs than the typical end user. And many end users - even before CR said anything - had already been reporting these same problems... so it seems darn obvious there is an issue, whatever Apple's "advanced and extensive" internal testing may (or may not) indicate.

        That's kind of the point of Consumer Reports... to test things the way typical real-world people do.

        And, frankly, we don't know if there was some subset of Apple's internal tests which did indicate this sort of issue, but the company decided weren't critical enough to cause them to hold production. The iPhone 4 antenna issues showed it can - and does - happen. Heck, how did Samsung release an exploding phone, if all these companies' "advanced and extensive" internal testing is infallible?

        I'm kind of mystified by the abuse of CR testing here. There's kind of a meme that CR can't test anything besides blenders, AFAICT it originated back in the day when they started testing stereos and audiophiles got bent that their testing wasn't judging whether exotic equipment produced the exotic sounds or wasn't using the requisite 00 gauge welding cable to connect the speakers.

        They're not disassembling the batteries and running the cell material through a mass spectrometer or conducting elaborate electrical tests of the batteries themselves; they don't need to.

        What they do need to do is design reasonable structured tests of laptop usage and keep track of the battery's lifespan during these tests and compare it to the manufacturer's claims. That's well within CR's ability and it's perfectly valid. Either the computer battery does what the manufacturer claims it will do or it doesn't.

        What CR is likely complaining about is that Apple modeled their battery life on some average use pattern that's not very realistic or very easy to deviate from in ways that seriously affect battery life.

        What Apple should have done was modeled their battery life based on more intensive use cases. But of course then you can't make the laptop even thinner and the battery even smaller and then make long life battery claims. IMHO Apple is a victim of their own thinness obsession and is fudging the numbers to make it look positive.

      Phil is definitely "on" this, even reaching-out to individual Users who have Responded to his Tweet on CR, asking them to send him certain specific Logs to help Apple diagnose this problem.

      CR will work with companies regarding details of test conditions and procedures to help them isolate any problems the testing might have turned up (which is probably the case here).

      The actual products that are tested though are bought off of store shelves by undercover CR employees posing as regular customers. That way a company can't rig the actual sample of the CR product being tested, unless they're specifically invited by CR to see if the product is defective (which has happened a few times with cars which failed some of CR's minimum safety tests.)

      This is one of the reasons I maintain a CR subscription even though the vast majority of their testing is too "average user" to be relevant to me. I think it's incredible valuable to have at least some published reviews based on random samples, instead of manufacturer-provided samples.

Users might accept that, as many people don't depend on the battery all that much. The ultimate deal breaker is soldered SSD. When that fails (and it will), the computer is junk.

      This problem (after a few years, battery life being half what it was when new) has pretty much been solved with larger battery capacities and lower power components. Lithium-ion batteries do degrade this way based on the number of charge/discharge cycles. But the depth of discharge matters more [batteryuniversity.com]. A battery which will only last 300+ cycles when charged to 100% and discharged until dead, can last 1200+ cycles when charged to 75% and discharged to just 25% before being recharged. The relationship is non-linear - reducing the cycle depth by half results in about triple the battery longevity. So it isn't just a matter of shallower discharges using the battery less. In other words, the worst thing you can do to the battery is to charge it all the way to 100% and discharge it all the way to 0%.

      Most newer batteries integrate this into their design. When they report 100%, the battery is actually at 80% or 90%. When they report 0%, the battery is actually at 10% or 20%. The Li-ion battery packs in EVs are a good example - they're limited between 20%-80% charge, or 15%-85% charge. Many laptops also add software which further limits the charge - stopping the recharge process when the battery reads 80% or 90% (which probably corresponds to 65% - 80% of the battery's real capacity). Couple this with the user making sure s/he never discharges the device completely, and you've eliminated the deep charge/discharge cycles which degrade the battery the most.

      In the old days, laptops used a lot of power and batteries were bulky. So manufacturers had to use 100% of the battery's capacity just to eek out 2-3 hour battery lives. This is what led to many of those batteries dying after a few years. Nowadays, battery energy density has improved, and mobile electronics use a lot less power. So manufacturers can put in a small or medium-sized battery in a laptop and still get 5-8 hours using only 60%-80% of the battery's capacity. So they've taken advantage of this to replace the swappable battery with an integrated battery and cut down on weight and size. The charging circuitry limits it so it can't actually charge to 100% or discharge to 0%, thus allowing these integrated batteries to be used for well over 1000 cycles - usually more than enough to last the lifetime of the device.

        You are correct about managing battery charge level, power drain, depth of discharge, etc. But it's not easy to get 4 solid years of service out of ANY battery in a portable electronic device. Does it happen? Sure. Reliable? Depends on who you ask. 1000 cycles is about 3 years of everyday use, maybe 4 years of Monday-Friday use. Managed batteries work reasonably well on phones. Then again, phones take a beating; the average user can be expected to lose or break their phone before the battery dies. Most laptops are not subject to that much physical abuse. I'm OK with a phone that lasts 3-4 years, but I expect more out of a well-maintained laptop.

        Apple seems to think that battery lifetime is good enough to limit the number of in-warranty replacements, while not so good as to extend the useful life of the product beyond 4 years. They may be right, but I'm not so sure a 4-year disposable laptop is worth what they ask for it.

            Many laptops are actually used as desktop computers most of the time, plugged into their charger, occasionally taken into a meeting or used on the train. In that scenario the battery will last forever. If it's used as a pure desktop computer, it doesn't even matter whether the battery is absolutely shot.

      • Although the general point is probably correct that min/max charge levels affect Li-ion lifespan, I would be careful with using batteryuniversity as a source of information.
