I have a Playstation Vita and I swear that after one particular upgrade to its firmware, my battery life got cut in half. I thought it was just my imagination or finally taking notice of how long I'd had the thing. However, I found a few other users on forums reporting the same issue, with one offering the possibility that the firmware has a new protocol for the Wi-Fi antenna. I don't have the exact post, but it was something about refreshing more often or using more power. If this sounds familiar, you've likely been following the news of Apple slowing down performance of older phones for the sake of preserving battery life (or not, depending on how you read the nuance of various conflicting statements).
So, as an iPad user who uses an iPhone as a backup for my Android daily driver, here are my thoughts on Apple's whole battery "fiasco".
I don't care.
I'm not going to go so far as to say #appledidnothingwrong because that's fueling a fire that nobody asked to have started. As far as big corporate deceptions go, this is small potatoes. When I was at T-Mobile, HTC had this "hybrid" style of smartphone (bit of a last hurrah before Android) with battery life so atrociously below specifications that they offered trade-ins for bigger battery packs.
From my perspective, as someone who got to see the Google G1 phone in person months before any consumers got their hands on it, Apple's exclusivity deal with AT&T was a massive blunder on their part, but also the very definition of serendipity. I have no doubt we'd have gotten Android phones anyway, but that "power vacuum" created by Big Mama Bell had an undeniably immeasurable impact on the smartphone landscape. Smartphones were now for everyone, and everyone deserves as many options as possible for the consumer-based economy to work best. Some people like to tinker with what they buy, while others just want the damn thing to work as advertised.
My point is, if you're just joining us, welcome to the wonderful world of how upgrades work for Apple fans. You trade customization for stability, and that stability means every few years you get a whole new machine. That sounds cynical, and even condescending, but it's really what Apple users have expected, asked for, and gotten in spades since the beginning. They want their creative productivity machines to be super easy to use and ready to roll right out of the box. In short, Best Buy's Geek Squad is an aftermarket version of Apple's entire business model. If you own a Mac, chances are the most work "under the hood/bonnet" work you've ever had to do with it is upgrade your RAM. Now, by a show of hands, who knows what RAM stands for? Don't be embarrassed if you don't know. As far as adventures in technology goes, RAM upgrades are like changing a diaper or your car's oil. It may not be intuitive or obvious, and can certainly seem daunting, but you can be walked through the whole process in about 2 or 3 steps.
If you're an iPhone user, you're only holding onto your phone because A) it's still working fine for what you need and you probably don't use it enough to even notice the battery's gradual diminishing, B) you've upgraded and it's now a backup in case something goes wrong with your new one, or C) it's good enough as a hand-me-down or something to occupy a kid or other family member who only needs it for something specific. Speaking of specific needs for family members, check out Music and Memory if you've got a few old iPhones, iPods, or even iPads resting in drawers.
In my admittedly limited experience with Apple's iPhone line, they're sort of like the original Star Trek or Batman films in that every other iteration seems to get things right. For example, the iPhone 2 was panned by critics for having a lackluster camera despite a high price tag (their Macbook Air had the same problem). Later, the iPhone 4 became a laughingstock because you literally couldn't hold it in your hands without interfering with its reception. The iPhone 6 gave us #bendgate, enough said. More recently, the iPhone 8... well, admittedly those swollen batteries were a rare occurrence possibly blown out of proportion, but they didn't address complaints about the headphone jack from the iPhone 7, so we'll count that as a missed opportunity. Jury's out on the X, though that facial recognition feature causes more problems than it ever solved. Not only can it be fooled by an embarrassingly crude mockup, but if you're under arrest, a cop can unlock your phone just by pointing it at you. It's a scary prospect.
As for the odd-numbered lot, I can only really speak for the iPhone 5, which is damn near perfect. The most important feature was the variety of 5 models available. There was the standard 5 and the slightly nicer 5s, but then there was the 5c. Intended as an economy/budget-level device, I had a 5c and while it definitely felt like its price tag, it still felt way more solid than any similarly-priced Android phones, and the display alone ran circles around the competition. Later, after I'd finished having my laugh over the 6, I admit to getting genuinely excited for the iPhone 7. Sure, the headphone jack was nowhere to be seen, but they'd given us an awesome camera and finally, finally made it at least splash resistant. For comparison, my Xperia Z Ultra is about 3 years old and nearly every review you'll see from its launch has it getting dunked in a fish tank. It's a small gesture, but I'll take it.
Building on the success of the 5, Apple made another smart move that may not quite fit the odd-numbered pattern, the SE. The phone has almost identical dimensions to the 5s, but with upgraded guts from the bendy 6. In terms of price, it's filling the same position as the 5c. Sadly, this is a model that's been listed as afflicted by the battery throttling. That said, I've had mine for a few months, and I haven't noticed it. Then again, I only have it as a backup for my Xperia, the same as my old 5c, which I'll be carting off to Music and Memory along with my old iPad Mini 3. I'm sure whoever gets them won't mind some less-than-stellar battery performance.
