display

The display with 5-inch screen is one of the below-average in the test. For everyday use, it is easy to use. But who has higher requirements – for example, photo apps, detailed games and more – the likely disappoint the image resolution. In the rather large area brings Sony the M4 Aqua Dual “only” normal HD below. That’s enough for a clear picture of falls compared to many other models but significantly.

With 1280 × 720 , the pixel density is slightly lower than the limit of 300 dpi. Individual pixels can be so even without a magnifying glass see. Of course that criticism at a high level. However, Sony requires indeed a neat pile of money for the Xperia M4 Aqua. Color intensity and contrast are ok, brightness and viewing angles very well. At the brilliance of (expensive) Xperia Z5 Dual or the award-winning Galaxy S6 (test) but it does not approach by far.

Xperia M4 Aqua Dual Camera

Flat: The only 7.3mm thick Xperia M4 Aqua Dual displays in the test with its two-stage camera button even from the outside, that the manufacturer has included a variety of multimedia features.

 

Design & Appearance

The most important detail is of course waterproof casing which at the same time prevents dust. The tightness in both categories is specified in IP classes: The higher the first and second number, the better the protection against water respectively dust particles. In both disciplines, the M4 Aqua Dual has stood the test of certification were very good.

The respective highest grade (IP65 for dust and water IP68) means that the dual SIM device is ideally suited for wet or dusty applications. The mobile phone may come in the rain, besides you can wash off dirt and grime under running water. According to classification, it can submerge to a depth of 1.50 m for half an hour.Sony itself does not recommend in his descriptions but from curiously.

It is important that the protection classes apply only when all connections are closed. In addition, they apply only to clear water or rain: salt water and other compounds, such as soft drinks, the M4 Aqua can hurt.

Aside from these advantages, the design has light and shadow.

  • has really liked the flat design (7.3 mm) and rounded sides, the more advantageous are also in an impact than the previously very angular shape of Xperia models.
  • Not so nice: The entire frame takes up more than a third of the front, the display just under two-thirds. With 135 grams of the M4 Aqua weighs on a 5-inch phone for a pleasantly low.
  • From metal no trace: Frame and back are made of plastic, this is designed as if it would be a metal frame and a glass surface. With a quick glance at the test can not tell the difference.

camera

That Sony historically a multimedia group is, makes the M4 Aqua Dual quickly noticeable. On the right side of the phone is next to the on / off and volume up / down buttons and a specially marked with camera icon trigger, which works in two stages. So it is quite simple point and shoot, how similar it knows well of pure digital cameras.

Top left on the back of the main camera is untergerbacht that dissolves with 13 megapixels (compared to 8 megapixels in the predecessor). The Exmor RS sensor for mobile devices is a derivative of the sensor technology as it is used in the Sony cameras. He makes as from other models usual good work. HDR is available not only for pictures but also for filming.
The selfie camera on the front above the display is next to an average 5-megapixel chip, especially on a wide acceptance angle.The 22mm lens covers almost a right angle: With 88 ° one can in a M4 AquaTest unquestionably accommodate smaller groups well on a single photo. The image quality of both cameras is more than average, but not high-end

Mobile Internet

Basically, the M4 Aqua supports all major standards in Germany, ie 2G, 3G and 4G ( LTE ). However, there are in the dual SIM series two slightly different models, which differ in the transmission standards. Here one must therefore necessarily look closely if you want to buy the Sony Xperia M4 Aqua Dual. The differences in detail:

  • Model series E2333, E2363: LTE, UMTS / HSPA and GSM / EDGE on each all German bands
  • Model E2312: No LTE, otherwise as the other two model lines

SIM slots

One needs two SIM cards in the nano-SIM format. The Xperia M4 Aqua Dual you can both with the two SIM cards as well as operate in addition to a microSD card. Unlike some “hybrid” smartphones in our comparison of the 2 SIM therefore does not need to share the same slot with an alternative microSD.

power

At the speed most clearly seen with the difference of the M4 Aqua Dual for Xperia Z-series from the same manufacturer. Here, the M4 is in midfield, but can not compete with the Super Phones like Galaxy S6, LG G4 Dual or just Xperia Z5 Dual.

The main reason for the difference in the comparison, the M4 sets instead of Snapdragon 810 on a less powerful Snapdragon 615. The octa-core processor consists of two quad-core Cortex-A53 chips together, one of which is clocked at 1.5 GHz, the other with 1.0 GHz.With 2 GB of memory, the M4 Aqua Dual is also “only” mediocre equipped. Up to 4GB of the currently best phones offer the test.

What does this mean for everyday life? Who wants to surf especially social networks uses or wants to play popular games buyer, has ample power reserves with this Sony smartphone. Lightning fast switch between apps smoothly scroll through menus: No problem.For 3D racing games, long Full HD video or complex apps, the model is not particularly recommended. In addition to speed problem, it is then also quite hot.

battery pack

The Xperia M4 Aqua Dual comes with a (for the display size) quite usual 2400 mAh battery. Nevertheless, Sony promises a long life of up to 2 days.

For particularly good stamina an “Extended standby mode” is installed. Thus, the mobile phone all the apps and other processes switches off, while the display is off. Incoming messages or calls on both SIM cards reached then still. In the test, so were possible even for 3 days. And with the “Ultra Stamina” mode, you can restrict all functions on the most important, so you still brings out a little time left.

The battery itself can not be removed and therefore do not change themselves.
