What are the best smartphones to choose for their autonomy in 2022?


Autonomy is an essential criterion when buying a smartphone! To help you choose the most autonomous, here are the smartphones that lasted the longest during our tests.

The most autonomous smartphones: the top 3

Who has never been stressed by the fear of running out of battery? Or lose contact with someone in the middle of an emergency call? Or in a meeting? While external batteries can possibly alleviate the problem, it’s far from the most user-friendly solution. To do without it, it is better to choose a smartphone with a long battery life.

To carry out its smartphone tests, the Frandroid newsroom uses the SmartViser app. It allows us to compare with the greatest possible precision the autonomy of each of the terminals that pass through our hands. You will find all the details about the autonomy test conditions in this article, but keep in mind that we relied on these results to produce this guide, which therefore excludes terminals where Viser did not work. The classification is made in decreasing order of autonomy.

Keep in mind that the most autonomous smartphones are not always the best overall. So it might be worth sacrificing some stamina for a better overall experience. Looking at things from this angle, several smartphones stand out, such as Google’s Pixel or Apple’s iPhone 13 Pro Max. Very durable, the latter, however, could not get our SmartViser test battery to work.

Because sometimes you may need to charge your smartphone anywhere, don’t hesitate to read our guide to the best external batteries. Still in the field of charging, don’t hesitate to take a look at our selection of fast chargers and Qi wireless chargers.

xiaomi redmi note 11

  • Two and a half days of use!
  • a solid design
  • A good price-performance ratio


Available in €199 on Amazon

The Xiaomi Redmi Note 11 was one of the most anticipated entry-level smartphones of 2022 and it does not disappoint. If the design is very classic, we still appreciate a clean finish along with a generally comfortable grip.

On the display side we find like last year a Full HD+ OLED panel, however the latter is now capable of a 90Hz refresh rate. Add to that completely honest colorimetry and brightness and you have the best display around. of the time in this price category.

The Snapdragon 680 offers very decent performance, but above all it is extremely efficient when combined with the 5000 mAh battery. So we endured without the slightest concern two and a half days in a position. And as a bonus, the 33W fast charge does an excellent job, with a full tank only taking 1h15.

The part in the photo is less impressive, but it provides the service quite well. The Redmi Note 11, however, lacks flaws due to a buggy software part in the core. Xiaomi has a lot of work to do here on the OS side.

Despite this drawback, the Redmi Note 11 stands out as a very good option for small budgets looking for good autonomy. You can find out more in our Xiaomi Redmi Note 11 test.

Realme 8i

  • A 120Hz screen
  • Autonomy
  • Realme UI 2 very nice


Available in €169 on Amazon

The latest addition to the Realme range, the 8i joins an already very large family. However, it stands out as one of the most affordable 120Hz display devices on the market. While not everyone will be a fan of the ultra-bright, fingerprint-picking design, it can’t be said to go unnoticed. However, nothing to complain about the build quality.

The LCD screen is a very good surprise, not only is it 120 Hz (non-adaptive), but its brightness is very correct, as are its colors. However, we are less convinced by the photo module. Although there are three sensors present, only the main one is really interesting. The quality of the macro and black and white sensors is simply too low to be really usable.

The Helios G96 SoC is more than adequate for an entry-level phone. There are some very minor slowdowns, but nothing too bad. We also very much appreciate the many customization possibilities that Realme UI 2 offers.

Between the less greedy processor and the 5000 mAh battery, Realme manages to offer us a phone with good autonomy here: 16:40 under Aim. As is often the case with entry-level smartphones, charging isn’t fantastic. The supplied charger takes just over two hours to reach 100%.

Without being revolutionary, the Realme 8i stands out as a balanced smartphone that offers excellent value for money for small budgets. We tell you more in our Realme 8i test.

Wiko Power U30

  • The price
  • Autonomy
  • Not much more…


Available in €159 in Cdiscount

Are you on a shoestring budget and need a phone that will last as long as possible? The Wiko Power U30 may interest you. Given the price, we do not expect much in terms of finishes and these fears are confirmed once in hand with a noticeable game in the assembly. Also, at 6.8 inches and 214 grams, the U30 is a real heavyweight.

If the screen is large, the panel is nevertheless mediocre, with low brightness and a colorimetry that will not be remembered. If we can tolerate a screen that does not break the house, the processor instead bothers us more. The Helio G35 simply lacks punch and struggles as soon as it gets out of very basic uses.

Fortunately, the phone shines with its stamina as the 6000 mAh battery allows it to last almost 4:30 pm under Aim. A value that translates into two or three days of use. As is often the case at this price level, charging is not very fast as it will take 2h15 to reach 100%.

If it lives up to its contract when it comes to endurance, the Wiko Power U30 doesn’t shine at much else. However, if you don’t have much money, there is still an option.

Samsung Galaxy S21 Ultra

  • photo quality
  • the screen is very good
  • A truly durable top of the range


Available in €859 on Rakuten Marketplace

Do we still have to present the Galaxy S21 Ultra? Samsung’s flagship is also one of the toughest phones we’ve ever tested. We greatly appreciate its careful design as well as its impeccable finish.

The 120 Hz OLED screen is simply one of the best on the market, both in terms of brightness and color quality. The photo is the other great strength of the phone, with excellent overall quality and a 10x zoom that opens really interesting doors.

If the Exynos 2100 is not the most powerful processor of the moment, it is still at the top of the basket. But above all, the 5000 mAh battery has no problem absorbing this wave of advanced technologies since we lasted 16:20 in our tests. Fast charging is average, with almost an hour to fill the accumulators. Too bad, however, that Samsung did not see fit to deliver a charger. Considering the price, it’s a bit stingy.

Therefore, the Galaxy S21 Ultra is one of the best smartphones on the market and, as a bonus, one of the most durable. You can’t find much better today. To learn more, read our Galaxy S21 Ultra review.

Google Pixel 6 Pro

  • Very high-end under €1000
  • photo quality
  • good autonomy


Available in €899 at Fnac

With the Pixel 6 Pro, Google arrives with the declared ambition to come and fight with the best in the very high-end field. We have to admit that the phone stands out with its gigantic photo module and its original lines. However, the Pixel 6 Pro will require both hands for comfortable use.

Nothing to say about the screen, Google has chosen a very good 6.7-inch panel. Between high brightness, very good colors and adaptive 120Hz, we tick all the boxes for an ambitious phone. Under the hood, we also discover Google Tensor, a SoC designed with Samsung. If it doesn’t have the power of a Snapdragon 888, it shines on the other hand with its photographic capabilities.

Photography remains an area where the Pixel excels, with great shots and algorithms that work miracles in low light. Finally, autonomy is excellent: we arrived at 4:10 p.m. in Aim and we endured the two days of classic use without worries. The only black point: a charge that is only fast in name, since it takes two hours to fill the battery. Too bad also that the supplied charger cannot be recharged at full speed.

The Pixel 6 Pro is undoubtedly one of the best smartphones of the moment and this includes, among other things, first-class autonomy. And as a plus, it offers a quality-price ratio that is difficult to match. We present it to you in detail in our test of the Google Pixel 6 Pro.

Everything you need to know about the autonomy of a smartphone

How do you rate the autonomy of a smartphone?

To test the autonomy of smartphones, we use the SmartViser tool, whose protocol we have established to better simulate daily use. Other media use the same tool, but with a different protocol, which explains why the results vary from one media to another.

For more details, you can consult our article dedicated to how Frandroid tests smartphones.

What affects the battery life of a smartphone?

The battery life of a smartphone varies based on several factors. The most consuming elements of a phone are: the screen, the SoC and the modem part. The larger the screen, the more it consumes, the more the processor is used, the greater its consumption. This is why a gaming session has a more noticeable impact on battery and stamina than web browsing, for example. So far the general rules, but a large screen is not necessarily a guarantee of little autonomy, and vice versa.

What is the recommended battery capacity?

In smartphones, the capacity of a battery is usually expressed in milliamp-hours (mAh), and the more, the better. Currently, the vast majority of phones have a capacity between 3,300 and 4,300 mAh. But beware, this figure can be misleading, because not all terminals consume so much. A small phone with a small battery can work just as well as a large smartphone with a large battery. That said, 5,000 mAh is usually a good sign.
