It’s not your imagination: Phone battery life is getting worse

Despite some notable exceptions, many 2018 smartphone batteries can’t keep up. Here’s why — and what we can do about it.
Phone makers promise “all-day battery life.” Sure, and you haven’t stolen any of the kids’ Halloween candy.
If you recently bought a new flagship phone, chances are its battery life is actually worse than an older model.
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.
My test has limitations. Your experience will depend on how you use your phone, and there are steps you can take to make your phone life stretch.
We’re not without hope. Two phones that performed well in my tests, Samsung’s Note9 and Apple’s iPhone XR, offer ideas about how to design phones to last longer — at least until a totally new battery tech comes along.

Why your phone battery dies

My results made me do a double take, so I called up a squad of other tech journalists also obsessed with testing at CNET, Tom’s Guide and Consumer Reports. “Our overall average battery life is coming down,” says Mark Spoonauer, the editor in chief of Tom’s Guide, who also found the iPhone XS battery died sooner than the iPhone X. Many of the phones with the longest battery life, he adds, are a year old.
But not all other reviewers have noticed the same declines — and the differences in our results help shed some light on what’s going on.
Larger phones often last longer, but it’s not as simple as the size of the battery inside. Remember the Blackberry? Those had much smaller batteries than today’s smartphones, but could go days without being charged.
There’s no perfect battery test. Mine, which I borrowed from an industry group called the Embedded Microprocessor Benchmark Consortium, particularly stresses the screen.
I use a light meter to set all the phones at the same brightness and then force their web browsers to reload and scroll through a series of sites I serve through a local WiFi network. I rerun the tests as many times as possible, and then average the results.
CNET, which like me found conspicuous dips in battery life between the iPhone 8 and iPhone X (and Samsung’s Galaxy S8 and S9), tests screens at 50 percent brightness playing a looping video with Airplane Mode turned on.
What we both discovered: phones with fancy screens that are especially high-resolution or use tech such as OLED perform worse. (That tech can require more power to push out light.) So if you want your phone to last longer, turn down the screen’s brightness. Or stop looking at your phone so many times each day, if you can break our nationwide spell of phone addiction.
Tom’s Guide throws another factor into the mix: the cellular connection. It makes phones run through a series of websites streamed over LTE. Unlike me, it also saw a big battery life hit to the Pixel 3 XL versus the Pixel 2 XL.
Another lesson: If you want the battery to last longer, use WiFi when possible — or even Airplane Mode when you don’t need to be reachable. Both Apple and Android phones also offer low-power modes (not reflected in our testing) that reduce some draining data functions without taking you offline.
The counterexample is Consumer Reports, which found the new iPhone XS lasted 25 percent longer than last year’s iPhone X. Its test uses a finger robot — yes, you read that right — to make phones cycle through lots of different functions and apps, including pauses in use where the screen turns off.
Consumer Reports is likely better testing the phone’s processor, an area where a number of companies — but particularly Apple — have made efficiency gains.
So overall, are battery lives decreasing or increasing? “You can’t make a straight trend,” says Consumer Reports director of electronics testing Maria Rerecich.
I wish companies had more standardized ways to talk about battery life. Since the earliest days of the iPhone, Apple has described battery life through specific measures, including “talk time” and “Internet use.” Recently it’s also taken on some more squishy language: The iPhone XS “lasts up to 30 minutes longer than iPhone X,” it says, a measure based on data about how long people go before plugging back in.
How phones are dealing

So what about the two 2018 phones that did better in my tests?
Samsung’s Note9 succeeds by stuffing in more battery. It contains a battery capacity of 4,000 mAh, up from the already-huge 3,300 mAh in the Note8. (The iPhone XS battery is only 2,659 mAh, and actually slightly downgraded from the X.)
Lots of phones have followed the bigger battery trend. iFixit, a repair community that performs teardown analysis of phone components, says battery capacities have almost doubled in the last five years.
How much further can the size game go? Huawei just introduced a phone called Mate 20 Pro, not sold in the U.S., with a 4,200 mAh battery. Larger, denser batteries can be more dangerous (remember Samsung’s exploding Note7?), not to mention heavier. The Note9, which also has a giant screen and a stylus, weighs 7.1 oz — more than twice a deck of cards.
Apple’s iPhone XR, the new phone I recommend to most people, has a different approach. It scales back on the screen tech — lower resolution, less bright and lower-quality color — in ways that benefit battery life tremendously: The XR lasted 3 hours longer than the top iPhone XS, even though the its screen is actually a smidge larger. (Bonus: It also costs $250 less.)
“Consumers have to start getting ready for compromise,” says Maluf, the CEO of the battery optimization company.
Perhaps the market will fragment further, making phones more like buying cars. That market was eventually upended by fuel-economy models; instead of the gas-guzzling Cadillac, you could choose the Honda. Apple’s iPhone XR is the Civic of smartphones.
Our near-future choices are likely either: Get an economy phone — or plug in more often. Faster and more convenient charging is the strategy for some makers. Lots of phones now support wireless charging, though still few cafes, offices and airport lounges offer it.
And then there’s the plug itself. Apple, which has shipped the same 5 watt charging brick for years, could take a lesson from Google, which sells its Pixel phones with an 18 watt charger and claims you can get 7 hours of use from just 15 minutes of charging. The one thing that’s almost as bad as running out of juice is being tethered to an outlet.

Apple iOS 12.1 Has Serious Problems

iOS 12.1 has landed and it is Apple’s AAPL +1.57% first major upgrade to iOS 12, bringing some major new features and important fixes. Unfortunately, however, it comes with two significant problems of its own…
The first is something that has become an increasing concern for Apple: lockscreen security. In short: a hack was discovered to bypass Face ID and Touch ID giving hackers access to your personal contacts. Moreover, the hack was found within just two hours of iOS 12.1 being released and it’s worryingly simple.
Shown off by in the video below by security researcher Jose Rodriguez, the hacker simply calls your iPhone from another iPhone and, once connected, the call is turned into a FaceTime video call and ‘Add Person’ pressed on the target iPhone. This brings up the device’s full contact list and using the 3D Touch shortcut on any contact reveals additional data such as their phone numbers, email addresses and more.
The flaw is specific to iOS 12.1 as it doesn’t work on any other version of iOS and, ironically, it affects premium iPhones most as cheaper models like the iPhone XR and iPhone SE don’t have 3D Touch.
But the biggest worry is how fast this hack was discovered.
Apple loves to promote its devices as having the best security in the industry, but this hack is far from a one-off. Rodriguez has found simple lockscreen bypasses in every iOS 12 release so far, with two in iOS 12 (1,2) and another in iOS 12.0.1 (link) prior to the iOS 12.1 hack today.
As for the other iOS 12.1 problem, iPhone 8, iPhone 8 Plus and iPhone X owners might want to look away now.
Despite Apple promising owners of these phones last year that they would not be subject to the same controversial performance throttling the company applies to older iPhones, iOS 12.1 has introduced it for all three models.
Forbes’ Ewan Spence has written about this, and Apple already faces almost 60 Class Action lawsuits in the US and legal action from multiple governments around the world for silently introducing what many deem is ‘planned obsolescence’ and Italy has already issued fines. So iPhone XS, iPhone XS Max and iPhone XR owners, clearly it will be your turn this time next year.
And note, this may not be the end of the problems.
My iOS 12.1 Upgrade Guide reports cases of graphics glitches, WiFi problems and battery life complaints. So you would be wise delay your upgrade unless you suffer from one of the flaws it does fix.
All in all, it’s a disappointingly rocky start for iOS 12. Especially given Apple has promoted it as being a back-to-basics focus on speed, stability and security. On the plus side, iOS 12 is packed with numerous secret featureswhich show Apple does still care about finely crafting its software.
What next? I would expect iOS 12.1.1 to arrive as a dedicated bug fix before the end of November. Unsurprisingly, Apple has already announced it is in beta testing…

Should you upgrade to Apple’s redesigned 2018 iPad Pro?

In last year’s review of the 10.5-inch iPad Pro, AppleInsider called it the king of tablets. Apple’s new 2018 iPad Pro is so much better in so many ways that it is hard to even think of what to call it.
The main question that many existing iPad Pro owners will be asking is if it’s worth upgrading to the new iPad Pro generation.
For starters, the new 11-inch base iPad Pro is priced at $799. If you’re planning on using the Apple Pencil, you also have to buy the new second-generation Apple Pencil for $129, bringing the base model up to a grand total of $928.
Even with that price, it’s easily has the power and features to make it worth that much.
This is the iPhone X story all over again, as the new iPad Pro is basically an iPad revolution. It’s packing Face ID that works no matter what orientation you hold the device, a refined exterior design, a new edge-to-edge display, the first USB-C port in any iOS device ever, support for a brand new Apple Pencil, and shocking performance.
Last year’s iPad Pro also shocked us by outperforming Apple’s 12-inch MacBook in both processor performance and graphics performance, and the new iPad Pro is supposed to double the graphics performance and almost double the processor performance of last year’s model.
Geekbench 4 benchmarks have already leaked, revealing the new iPad Pro’s processor is nearing the performance of Apple’s new 15-inch MacBook Pro, and it’s even closer to the performance of the best processor in the 2017 5K iMac. The new iPad Pro actually outperforms the best processor in the 2018 13-inch MacBook Pro, and even the best processor in the 2017 15-inch MacBook Pro.
Of course, this is just Geekbench 4, which doesn’t factor in thermal throttling, but the raw power is incredibly impressive.
Despite the difference in size, the 12.9-inch model is identical in terms of performance, making the decision to buy one over the smaller version more based the mass and the cost than anything.
So, let’s say you already have a 2017 iPad Pro. Should you upgrade? If money isn’t an issue. Face ID and the new display alone should make the upgrade worth it, and you could probably sell your current iPad Pro for at least $400 to 450.
If you’re happy with your current iPad Pro and you don’t have that much spare cash, just stick with the 2017 model for another year.
For owners of older iPad Pro models, I would definitely recommend upgrading. The biggest things those models lack is a very bright and color-accurate display, Apple Pencil lag improvements, and 120hz ProMotion technology, which really makes the new iPad Pros shine.
If you’ve got any other kind of iPad, you should only think about if you really need the performance and the Apple Pencil support. The 2017 budget iPad for $329 supports the Apple Pencil and has a decent A10 processor, but the display is definitely lacking.
Apple has just released a brand new Apple Pencil, and next years’ budget iPad will probably support it, which means it’ll also come with the new boxy design to incorporate it. If you don’t need the extra power and the amazing display, you could just wait until March.
Now some of you may be thinking about skipping this year’s iPad Pro in favor of the 2019 model. Here’s something to think about.
Apple basically went all out on this new iPad Pro, and there’s a lot of firsts in this generation; it’s the first iPad to switch to this boxy design since the original iPad, the first with an edge-to-edge rounded display, the first with Face ID, the first with a USB-C port, the first with support for the new Apple Pencil, the first with a 7-nanometer chip that outperforms a MacBook Pro, and it’s also thinner than any iPad or even iPhone ever, if you’re not counting the camera bump.
Speaking of the camera, it gets the same wide camera as the iPhone XS, with the latest video recording improvements and features like Smart HDR and Portrait Mode selfies.
Based on that, next years’ iPad Pro models are unlikely to be that much different, and since it’ll be running on the same 7nm architecture, the performance won’t see as big of a jump as this year’s versions. It’s doubtful Apple will switch to an even smaller chip architecture for at least a couple of years.
There may be some changes here and there, but the 2019 models will generally be very similar to the 2018 iPad Pro.
If you’re thinking of upgrading to an iPad Pro within the next two years, you might as well just just upgrade right now. That’s the same advice we gave when the revolutionary iPhone X came out, and as you can tell by the iPhone XS, there really isn’t much different apart from the larger iPhone XS Max.
Here’s the rundown: if you’ve got a 2017 iPad Pro and you’re perfectly happy with it, don’t upgrade unless you’ve got a bunch of extra cash. If you’ve got anything else and you’re thinking about getting an 11-inch iPad Pro within the next couple of years, seriously just upgrade right now, because the 2019 iPad Pro won’t be that much different, and it definitely won’t get any cheaper.
As for the 12.9-inch model, it’s $200 more expensive, but the chassis is now significantly smaller than the previous 12.9-inch iPad Pros, making it a lot more convenient to use. If you’re trying to use your iPad Pro as a laptop replacement, the 12.9-inch model will be the better choice if you have the extra cash, while artists will enjoy the extra screen space that the larger model offers.
