Best Flagship Smartphones From the Companies That Know How

Flagship smartphones from five of the biggest mobile phone makers compared. With the usual thinner, smarter, lighter, bigger, and the inevitable speed bumps from one generation to the next, how do these flagship smartphones compare with one another.

The Top 5 Best Smartphones

The market maybe flooded with smartphone manufacturers with their endless supply of smartphones of all shapes and sizes, a handful of more established manufacturers are pushing the boundaries of mobile technology to come up with their flagship smartphones.

We take a look at a comparative review based on specifications of the top 5 best smartphones in the industry from smartphone giants; Apple, HTC, LG, Samsung and Sony.

The Five Corner Shootout

Apple iPhone 6 vs HTC One M8 vs LG G3 vs Samsung Galaxy S5 vs Sony Xperia Z3. Here is a look at the spec by spec comparison [IN OUR COMPARISON]:

Processor, Memory, Storage

Only the iPhone 5S has a future proof 64bit processor. Sony Experia Z3, LG G3 and Samsung Xperia Z3 shares the same quad-core processor , the Qualcomm Snapdragon Quad Core Processor running at 2.5GHz. The HTC One (M8) has a slightly slower processor at 2.3GHz using the Qualcomm Snapdragon 801. The only phone with 3GB of RAM is the Sony Xperia Z3. The others uses 2GB RAM except for the iPhone 6 which seems to be content with just the 1GB. In terms of expansion, all except for the iPhone allows additional storage memory in the form of microSD supporting up to 128GB.

  • Apple iPhone 6: A8 processor with 64-bit architecture and M8 motion coprocessor, 1GB RAM, 16/64/128GB Storage [NO MICRO SD]
  • HTC One (M8): 2.3GHz Quad-core processor, Qualcomm Snapdragon 801, 2GB RAM, 16/32GB Storage + microSD (up to 128GB)

  • Sony Xperia Z3: Snapdragon 2.5GHz Qualcomm Quad-core, 3GB RAM, 16GB Storage + microSD Slot (up to 128GB) [HIGHEST CLOCK SPEED & RAM] 


Apart from the iPhone 6 (not the iPhone 6 Plus), all smartphones in our list has pretty big screens, 5-inch or bigger. We looked at the Top 5 Best Phablets not too long ago and the Top 10 Phabets in 2015 on our sister blog. It has smartphones with screen sizes up to 6.4-inch, starting from 5.7-inch. These big screen flagship smartphones are not that far behind with the biggest at 5.5-inch. Vendors are starting to blur the lines between their smartphones and phablet, with Full HD resolution and super bright and sharp screen. All with the exception of Apple iPhone 6 with lower than Full HD resolution and LG G3 with Quad High Definition or 4K 2560 X 1440 display.

  • Apple iPhone 6: 4.7″ (1334 x 750), 326 ppi or 5.5″ (1920 x 1080), 401 ppi
  • HTC One (M8): 5.0″ Full HD 1080 (1920 x 1080), 441 ppi
  • LG G35.5″ Quad HD (2560 X 1440), 538 ppi [HIGHEST RESOLUTION]

  • Sony Xperia Z35.2″ Full HD display (1920×1080 pixels), TRILUMINOS Display and X-Reality for mobile


Most smartphones that we have used do not last more than a day of semi heavy use. Vendors are putting power management features in place to turn off un-used features and notifications, introduce deeper sleep (leaving only minimal phone functions) as well as the ability to turn the colours on the display to black an white to save every drop of juice on the battery and to maximise the battery life per charge. On the other hand, vendors are also squeezing bigger and higher capacity batteries into the only thin packages. The best talktime is on the iPhone 6 Plus, and the best standby time is on the Sony Xperia Z3 with its stamina technology.

  • Apple iPhone 6: 1810mAh (talktime 14 hrs(3G), standby 250 hrs) or 2915mAh (talktime 24 hrs (3G) standby 384 hrs) on iPhone 6 Plus [BEST TALK TIME]
  • HTC One (M8): 2600mAh (talktime 14hrs(2G)/20hrs(3G), standby 271hrs(2G)/496hrs(3G))
  • LG G3: 3000mAh Replaceable with Wireless Charging Support (talktime 19hrs(2G)/21hrs(3G), standby 565(2G)/553hrs (3G))
  • Samsung Galaxy S5: 2800mAh (talktime 21hrs, standby 390hrs)
  • Sony Xperia Z3: 3100mAh (talktime 16 hrs, standby 920hrs) [BEST STANDBY TIME]



Smartphones are already replacing point and shoot digital cameras. With clever camera features, high pixel density sensors, flash, lenses, effects and editing software as well as ease of sharing, it makes sense to use the camera on the smartphone instead of carrying another camera. Features include dual shot, simultaneous HD video and image recording, geo-tagging, touch focus, face and smile detectio, image stabilisation, HDR, Panorama. Sony Xperia comes up on top with a 20.7MP rear camera while both LG G3 and Samsung Galaxy S5 have 13MP and 16MP sensors respectively. The HTC chose Dual 4MP Ultrapixel sensor each that can do some pretty clever stuff.  However, the actual output quality of the images may differ as there are other factors at play when it comes to taking a good image such as lense, lighthing and software optimisation.

  • Apple iPhone 6: 8MP, 3264 x 2448 pixels, phase detection autofocus, dual-LED (dual tone) flash. 1/3” sensor size, 1.5µm pixel size, geo-tagging, simultaneous HD video and image recording, touch focus, face/smile detection, HDR (photo/panorama)

Simply packing a phone with bigger numbers; faster processors, more memory, bigger storage, bigger screen, more resolution and more sensors are something that every vendor does. So how are vendors differentiating between themselves, the start to include

  • Apple iPhone 6: Report of body bending with iPhone 6 Plus, protective case is strongly recommended

  • Save

Note: IP stands for Ingress Protection, IP rating is a test certification to measure a device’s resistance levels to both dust and water. The first digit in the two-digit IP rating indicates the level of protection against solid objects, including tiny dust particles. The second digit indicates how resistant the device is to water.

Where phones are dust and waterproof, the micro USB port, micro SIM slot and memory card slot must be closed tight in order for this to work.
