It\'s not your imagination: Phone battery life is getting worseIt\'s not your imagination: Phone battery life is getting worseIt\'s not your imagination: Phone battery life is getting worse

Mobile phone manufacturers promise all
Battery life.
\"Of course, you haven\'t stolen the children\'s Halloween candy.
If you \'ve recently bought a new flagship phone, chances are it\'s actually worse battery life than the old one.
Over the past few weeks, I have repeatedly tested the same battery on 13 phones.
With some notable exceptions, this year\'s top models did not perform well last year.
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 Pixel 2.
To improve battery life, handset manufacturers have introduced a wide range of tips, including more
Efficient processor, low
Manage the power mode and AI consumed by the application.
However, my results and tests from other reviewers I spoke to reveal a public secret of the industry: Lithium
The ion batteries in smartphones are entering an inflection point and they can\'t keep up at all.
\"Battery improvements are very slow, about 5 cents a year,\" said Nadim Maluf, CEO of a company called Qnovo in Silicon Valley, which helped optimize the battery.
But mobile phone power consumption has grown at more than 5 cents.
\"Blame it on high demand
The resolution screen, the more complex app, and most importantly, we can\'t seem to put down the damn phone. Lithium-
For all of their charging wonders, there are also some physical limitations on the ion battery, including the capacity that goes down over time
If they are damaged or improperly disposed of, there is a danger of an explosion.
The power status of the phone may become worse.
The new ultra-fast wireless technology 5g is about to be launched in the United States. S.
In the near future, our community will make even greater demands on our troubled batteries.
My test has limitations.
Your experience will depend on how you use your phone and there are steps you can take to extend the life of your phone.
We are not without hope.
Two phones that performed well in my test, Samsung\'s Note9 and Apple\'s iPhone XR, offer ideas on how to design phones that last longer --
At least before a whole new battery technology comes along.
My results made me do a double test, so I called together a team of other tech reporters who were also obsessed with CNET testing in Tom\'s Guide and Consumer Reports.
\"Our overall average battery life is declining,\" said Mark Spooner, editor-in-chief of Tom\'s Guide, who also found that the iPhone XS battery died faster than the iPhone X battery.
Many phones with the longest battery life have been around for a year, he added.
But not all reviewers noticed the same decline.
The difference in our results helps to reveal what is happening.
Larger phones usually last longer, but it\'s not as simple as the size of the internal battery.
Remember the BlackBerry?
Their batteries are much smaller than the current smartphones, but they can be charged for a few days without being charged.
No perfect battery test.
I borrowed it from an industry organization called the Embedded Microprocessor Benchmark alliance, with a special emphasis on the screen.
I use a light meter to set all my phones to the same brightness and then force their web browser to reload and scroll through a range of sites I serve through my local WiFi network.
I re-run the test as much as I can and then average the results.
Like me, CNET found a significant drop in battery life between iPhone 8 and iPhone X (and Samsung\'s Galaxy S8 and S9), with airplane mode turned on, test the screen to play the loop video at a brightness of 50 cents.
We all found out: phones with particularly high screens
Resolution or worse performance using technologies such as OLED.
(More power is needed for lighting this technology.
) So, if you want your phone to last longer, turn down the brightness of the screen.
Or, if you can break our nationwide phone addiction, stop watching your phone so many times a day.
The Tom Guide adds another factor to this combination: cellular connections.
It enables mobile phones to transmit through a series of websites over LTE.
Unlike me, it also sees a significant increase in battery life for Pixel 3 XL and Pixel 2 XL.
Another lesson: use WiFi as much as possible if you want the battery to last longer-
Even when you don\'t need to arrive, airplane mode is OK.
Apple and Android phones are also low.
Reduce some power modes that run out of data features without affecting you (not reflected in our tests )-line. The counter-
Consumer Reports show the New iPhone XS is 25 age points longer than last year\'s iPhone X.
Testing with a finger robot
Yes, you read it right.
Let the phone loop in many different functions and applications, including suspending use when the screen is off.
Consumer Reports may better test the processor of the phone, in this field, some companies-
Especially Apple.
Efficiency is improved.
So in general, is the battery life decreasing or increasing?
\"You can\'t trend directly,\" said the director of consumer reporting for electronic testing Maria Rerecich . \".
I hope the company has a more standardized way to talk about battery life.
Since the iPhone came out, Apple has used specific measures to describe battery life, including \"call time\" and \"Internet use \".
\"Recently, it also uses some more sticky language: the iPhone XS is\" 30 minutes longer than the iPhone X, \"which says a data-based measurement method, about how long it will take for people to re-insert.
So what about two 2018 phones that did better in my test?
Samsung\'s Note9 has successfully filled more batteries.
It contains the battery capacity of 4,000 mAh, from the already-
The huge 3,300 mAh in Note8
(The IPhone XS battery is only 2,659 mAh and is actually slightly downgraded from X.
A lot of phones follow a bigger battery trend.
IFixit, the maintenance community that analyzed the removal of mobile phone parts, said that the battery capacity has almost doubled in the past five years.
How far can the size game go?
Huawei has just launched a phone called Mate 20 Pro, which is not sold in the United States. S.
When the battery is 4,200.
Larger, more dense batteries can be more dangerous (remember Samsung\'s explosive Note7?
), Not to mention heavier.
Note9, which also has a huge screen and stylus, weighs 7 lbs. 1 oz —
More than twice a deck.
The Apple iPhone xr I recommend to most people has a different approach.
It narrows the technology on the screen-
Lower resolution, lower brightnessQuality color-
From the point of view of greatly extending battery life: XR is 3 hours longer than the top iPhone XS, even though its screen is actually a little bigger.
(Bonus: $250 less.
) \"Consumers must start preparing for a compromise,\" said Marouf, CEO of battery optimization . \".
Maybe the market will be further divided. mobile phones are like buying a car.
Fuel eventually turned the market upside down. economy models;
Not gas-
You can choose the luxury Cadillac of Honda.
Apple\'s iPhone XR is a citizen of smartphones. Our near-
The future may be: Buy an economic phone.
Or insert more frequently.
The strategy of some manufacturers is to charge faster and more conveniently.
Many phones now support wireless charging, but there are still very few phones that provide wireless charging in cafes, offices and airport lounges.
Then the plug itself.
Apple, which has been shipping the same 5-watt charging brick for years, may learn from Google, which sells Pixel phones with 18-watt chargers, claiming that it will take only 15 minutes to charge for 7 hours.
One thing that is almost as bad as running out of juice is being tied to an outlet.
