Tests carried out by the Washington Post, CNET, Consumer Reports and Tom's Guide that battery-life is getting worse with each successive generation.
Experts believe that it's possible to continue for some time yet …

It's not a problem specific to iPhones, says the Washington Post, but something seen with Android flagships too.
For the last few weeks, I've been performing the same battery 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.
There is one exception on the iPhone front: the iPhone XR, with its LCD screen, offered the best battery-life of all. But the results otherwise show a gradual decline.
The battery-life of the iPhone was slightly worse than the iPhone 8. The iPhone XS did not last as long as the previous year's iPhone X. And the iPhone XS Max – despite having the largest battery – Did not last long as the iPhone 8 Plus.
That's in direct contradiction to Apple's claim that the iPhone XS 'lasts up to 30 minutes longer than iPhone X,' but the problem there, says the piece, is that there are no agreed standards.
Tea post's Geoffrey Fowler was so surprised by his results.
CNET, Tom's Guide and Consumer Reports. "Our overall average battery life is coming down," says Mark Spoonauer, Tom's Guide, who also found the iPhone XS battery died sooner than the iPhone X. Many of the phones with the long battery life, he adds, are a year old.
One industry expert says that's not surprising. The iPhone XS has a marginally smaller capacity than the iPhone X, but that's not the problem.
[There’s] An open secret in the industry: the lithium-ion batteries in smartphones are hitting an inflection point where they simply can not keep up."5 percent per year," says Nadim Maluf, the CEO of Silicon Valley firm called Qnovo that cheers optimize batteries. "But phone power consumption is growing up faster than 5 percent" […]
And the phone power situation is likely 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.
Apple puts a lot of work into power optimization, but it's not quite keeping up with the power demands of the performance increases.
What can you do to extend your battery-life, using your phone less? The main tips are to reduce screen brightness and to use Wi-Fi over LTE where possible.
In the tests, which made the phones surf the web constantly, the iPhone results were:
- iPhone XR: 12h 25m
- iPhone 8 Plus: 10h 10m
- iPhone XS Max: 10h 06m
- iPhone 8: 9h 51m
- iPhone X: 9h 30m
- iPhone XS: 9h 09m
The iPhone XR also beat the Android flagships tested, with Samsung's Note 9 taking second place.
Until the oft-promised battery technology breakthrough delivers results, it looks like Apple's obsession with performance boosts means we can expect a gradual decline in battery-life for some time yet.
