Becoming a category in its own right, smartphones combine a relatively compact template with exceptional functional richness for communication, work, and leisure. For demanding users.

While most smartphone enthusiasts swear by the speed of execution of tasks, others rely on duration and reliability by privileging a completely different aspect: battery. Here is just a selection of the best smartphones that do not need to be plugged into the mains after a day.
6 – Meizu M3
The M3 Note, a smartphone with a 5.5-inch display (LCD panel LTPS – 1920 x 1080p resolution), is now well-established in the niche of entry-level devices. The Chinese manufacturer offers you a device that certainly sags a little in terms of display due to the lack of AMOLED technology, but in terms of design and ergonomics, has a certain personable.

The proof is with its neat aluminum back, its fine screen borders, its good fingerprint sensor and its sides that make it a very nice terminal level grip. Nothing very original compared to a Pro 6 for example, but it has at least the merit of being effective! Where the Meizu M3 Note also strikes hard, it is the flagship criterion of this selection: battery. In fact, the machine incorporates a battery of 4 100 mAh, which allows it to remain in activity for more than one day, even in the case of versatile use (calls, SMS, Internet browsing …). Otherwise, easily count two days before you have to plug it into mains. Rather impressive!

The Meizu M3 Note is, on the other hand, a little behind the technical specifications. Its mobile chipset October-core MediaTek Helio P10 clocked at 1.8 GHz, its iGPU Mali-T860 MP2, both a bit “old-fashioned”, and its 2 GB of RAM, struggle to make it decisive in terms of video games. One feels that the device sometimes draws from its resources to try to turn a game a greedy hair. No difficulties, however, concerning various multimedia uses such as video playback, music, etc. Or to run the whole system Android 5.1 + FlymeOS 5.1.2. The fluidity is at the rendezvous, which makes the navigation frankly pleasant.

5 – Xiaomi Redmi 3
Xiaomi has made its mark on the mobile phone market and has made its mark on the mobile phone market. After a Redmi 2 more than correct, the Chinese manufacturer gives way to a mid-range successor not only very attractive but also very solid in terms of autonomy: Xiaomi Redmi 3.

This terminal is difficult to disappoint in terms of endurance. The Redmi 3 is a real war machine and can hold without flinching for two full days using its battery of 4 100 mah. Especially since it only takes a 5-inch screen with an HD resolution (1280 x 720p – resolution of 293 dpi), making it a low-power component.

It is even possible to preserve it even more in time by activating the “Marathon” mode, this minimizing the energy expenditure when the battery is below the 20% threshold. Practice not? The Redmi 3 is a real marathoner who, for sure, should not displease those who swear by the multimedia practices on their smartphone (videos on YouTube, streaming, video games, music …).
4 – Oppo R7 Plus
The Huawei Mate 8 makes you dream but its selling price rejects you a maximum? So you want a good alternative to this model that combines big autonomy and performances more than correct? The Chinese Oppo has what you need with a smartphone with an excellent screen AMOLED Full HD 6 inches: the R7 Plus.

Just the same as the Huawei terminal with a 100% metal shell, extremely thin screen borders and a very good overall finish – note the presence of a fingerprint sensor underneath Of the photo sensor – the Oppo R7 Plus is a relatively powerful phone (Snapdragon 615 processor and 3 GB of RAM) and formidable in terms of autonomy.

Using it on a daily basis is a real pleasure because of a 4,100 mAh battery that keeps you awake for almost a day and a half or even two whole days. Just what it takes for standard use (SMS, calls, internet browsing,) or more advanced use like watching streaming videos, playing games…

3 – Huawei Mate 9

A fervent representative of so-called “high-end” smartphones, the Huawei Mate 9 imposes itself without great difficulty as one of the best in terms of autonomy. By integrating a 4,000 mAh battery with its smartphone, the Chinese giant offers the possibility of being enduring in the long term.

Two days, this is the average endurance of this Mate 9 equipped with an IPS Full HD 5.5 inch and running Android 7.0 Nougat. This data can be rapidly revised downwards when used intensively, and the battery life can be estimated at one and a half days. Enough, ample even enough to indulge in long hours of streaming video viewing, gaming sessions, browsing the internet or other multimedia activity for hours.

At first glance, this Mate 9 has all the stuff of a superb smartphone. But then why is it only in the third place of this selection?

2 – Moto Z Play
Low autonomy has become a major problem in smartphones. The fault of what? Has more and more demanding applications, which use the batteries of the terminals in two movements three times. Lenovo says stop, through a particularly mid-range model that is the Moto Z Play.

Streaming, video games, music … everyone can enjoy this 5.5-inch (Super Amoled Full HD) smartphone, powered by a Qualcomm Snapdragon 625 8-core SoC (ARM Cortex- A53 2GHz), an Adreno 506 iGPU, 3GB RAM and 32GB storage space. What relatively powerful components for this Z Play running Android 6.0, which on top of that has the advantage to be recharged in USB-C and to be 100% compatible with fast charging.

Not forgetting the 16-megapixel photo sensor of this Moto Z Play that offers very detailed and sharp pictures. The front sensor of 5 Mpx meanwhile, tends to be quickly forgotten because of a very average quality. Just useful for taking some selfies!
1 – Asus Zenfone Max
Need a companion who can follow you everywhere and who is not likely to be flat after a day? Asus has what you need with a perfect endurance model that is the Zenfone Max.

This 5.5-inch smartphone (IPS HD Panel – 1,280 x 720 p) is the dream device for any user tired of having to go out with his charger in the pocket. For this, the Taiwanese manufacturer praises the merits of its foal by awarding him a 5,000 mAh battery. It may take a few hours less if you use it more often (video games, games …) but it can easily stand two days before you have to connect it to an outlet.

The only black point, the recharge time is extremely long, this one is estimated at 4h-4h30. Long, too long even will say some, but unfortunately, it is the price to pay if you want a smartphone with a great autonomy.
