Report : Does the 5,000 mAh battery on the ZenFone Zoom S really last for a day?

The ZenFone Zoom S was released from ASUS. It has both wide angle and telephoto cameras. It also has big battery capacity of 5,000mAh. I tested the ability of the camera and battery on a one day trip.

I definitely need a camera when I go on a trip. But I actually don't want to take a big camera with me as it can be an extra load. However, I don't want to waste money on a small mirrorless camera or a compact digital camera. I thought a smartphone might be able to do the job, but my smartphone doesn't last for a day and it is troublesome to carry a mobile battery.
That is when I hear about the ZenFone Zoom S from ASUS. It has both wide angle and telephoto cameras, and it also has a big capacity battery of 5000mAh. This should be fine for using it to take photos for a whole day, and it seems it can take beautiful photos easily with the high performance camera! So I went on a day trip in Tokyo with the ZenFone Zoom S.

Can I complete a day trip successfully using the ZenFone Zoom S as a camera?

Let's have a look at the basic specifications of the ZenFone Zoom S

Can a smartphone be a substitute for a camera? To answer this question, I went on a day trip in Tokyo using the ZenFone Zoom S as a camera. I chose places I always wanted to visit and the places where my colleagues recommended, and I did sightseeing at those places from the morning till night using the ZenFone Zoom S fully.
Before starting, let's have a look at the basic specification of the ZenFone Zoom S. Its CPU is Snapdragon 625, 4GB RAM and 64GB ROM. it has 5.5-inch OEL (1920 x 1080). ASUS had a smartphone called the ZenFone 3 Max which specialized in battery capacity, but this ZenFone Zoom S has a lot bigger battery capacity than that; it is 5000mAh.

The ZenFone Zoom S is 154.3 x 77 x 7.9mm HWD, and it weighs about 170g. It supports DSDS though it cannot be used with micro SD card together. As for network standard, FDD-LTE is Bands 1, 2, 3, 5, 7, 8, 18, 19, 26, 28, TD-LTE is Bands 38, 39, 40, 41. WCDMA is Bands 1, 2, 5, 6, 8, 19 and GSM is 850, 900, 1800, 1900 MHz. (TW/JP/HK/SG/PH version)

The score with AnTuTu Benchmark is 62730. It is about the same as the ZenFone 3 which has the same CPU. It worked lightly, and it had no problem in switching between apps and for playing 3D games.

The main camera is a dual lens camera with 12MP 25mm wide angle lens and 59mm telephoto lens. The wide angle lens is f/1.7 aperture, and has SONY IMX362 sensor. It has optical image stabilization. It supports 2.3x optical zoom and its total is 12x zoom.

Can I successfully finish my one day trip with the ZenFone Zoom S as a camera?

Now we are off to sightseeing in Tokyo. While travelling, I used this for playing music and for GPS, which uses a lot of battery. The photos from here are all taken by the ZenFone Zoom S except for the photos of the device itself and screenshots.

I left home at about 10 in the morning. I left the driving to my friend. I turned on the Bluetooth on the ZenFone Zoom S to connect with the car audio system to play Google Play Music.

I also turned the GPS on to use Google Maps. I am putting more burden on the battery. The brightness of the display is set to below half. I had the SIM card inserted, but I left the wi-fi on. Using the Google Maps and Google Play Music together would be a big burden on the battery, but let's go for a drive trusting the 5000mAh capacity!

After a 40-minute drive, we arrived at Tokyo Tower. I took photos with Auto mode. You can choose Auto, on or off with HDR, and it also has HDR Pro mode which you can intensify contrast.

HDR is on with Auto with the photo on the left. The right one was taken with HDR Pro mode. The photo taken with HDR Pro has stronger contrast and sharp color.

Arrived at the 150m tall main observatory.

Took a photo looking towards Roppongi Hills from the main observatory. You can take photos keeping all the details.

The ZenFone Zoom S has a telephoto lens that supports 2.3x optical zoom. But when it is below 2.3x zoom, it chooses the one more beautiful between optical or digital zoom automatically. The photo above was taken with 2 times optical zoom.

The photo taken with 12x zoom showed some noise. It was difficult to take steady photos with it, too. 6-7x zoom is more practical.

Took a lot of animal photos at the Ueno Zoo!

After looking around Tokyo Tower, I took photos of what I had for lunch, and I went to the Ueno Zoo by car. We again used Google Maps for GPS and Google Play Music to listen to music while traveling from Tokyo Tower to Nippori and Nippori to Ueno Zoo. I decided to check the battery remaining at the end of the day. I feel nervous if the battery will last.

A photo of "reimen," or cold noodles, taken with HDR Pro mode. It shows the color of the cucumber, ham and egg brightly, and looks appetizing.

We came to the Ueno Zoo after lunch. It was so hot, so it was not as crowded as I expected.

Even when animals are at a far distance, I can easily take photos with the zooming function. This was taken with digital zoom, but it works well in bright environment; I can take photos with little noise.

High speed autofocus allows me to take photos of sea lions moving around without missing the photo opportunity.

I took a photo of hydrangea in the zoo with single focus mode. This allows me to take photos focused on the object leaving its background blurred. After releasing the shutter, you can adjust the strength of the bokeh effect. For this picture, I adjusted the bokeh to the maximum.

Tried many modes at Senso-ji, then went to Odaiba to photograph night scenery

Two hours had flown by taking photos at the Ueno Zoo. I didn't get a chance to see everything there. We headed to Senso-ji next. I tried many modes of the ZenFone Zoom S at Senso-ji, which enabled me to take many interesting photos. I was very happy with it. Lastly, we went to Odaiba to photograph the night view to finish the day.

A 15-minute drive from the Ueno Zoo took us to Senso-ji.

This one was taken using one of the effect modes, the pencil effect mode. It looks like a pencil sketch.

I took this using LOMO, one of the effect modes. You can take photos as if you used a toy camera.

Took a photo from where both the Skytree and Senso-ji fit in the frame. It was a only a quick tour, but after enjoying this area for an hour, we headed to Odaiba.

Arrived at Odaiba at about 5:30PM.

Waiting for sunset while resting on the grassy area near the beach.

As it started getting darker, I took a photo using the night view mode. I was able to take beautiful photos even with hand-held shooting.

To take a brighter photo, I adjusted the shutter speed and exposure using manual mode. Because there were many people, I zoomed in to avoid people getting in my photo. It was a bit hard to take photos without using a tripod. I left the camera on for about an hour to take night view photos so I think it took up a lot of battery.

How much battery did the ZenFone Zoom S have left after being used fully for sightseeing in Tokyo?

I said good bye to my friend at Odaiba and took the train back home. At Odaiba I walked around using Google Maps, and on the train ride home, I surfed the Internet and watched YouTube videos. I was out for about 11 hours, but when I got home, the remaining battery was an amazing 23%.

It is excellent that it has 23% battery remaining after being used fully for a whole day.

We were in the car for about 3 hours travelling. I kept using Google Maps GPS system and Google Play Music during the travel. Also, I took about 350 photos. I left the ZenFone Zoom S on for almost a whole day, but it still had 23% battery remaining. It is just amazing.
The battery of the ZenFone Zoom S is more than enough for sightseeing for a day. It should last for two days easily for daily use. As for the camera, it has enough functions for a trip or sightseeing. Just taking photos in auto mode takes beautiful photos, which is another advantage of this smartphone. It has 64GB storage, so no matter how many photos you take, you wouldn't run out of storage easily. It supports shooting RAW, so users fussy with cameras would be happy with it, too. If you are looking for a SIM free smartphone with long battery life with good camera function, this would be the best choice.
