Samsung Galaxy S6 Edge vs Apple iPhone 6 vs HTC One M9 - Tech Battle and Battery Life

Smartphones have become a necessity for us to efficiently function in today’s society, and why not? They are amazing devices which give us access to the entire library of global history and knowledge at just a press of a finger away. Information that would have taken our grandparents weeks or even months to find in the local library is now accessible like never before. Yet, with any positive there is always a negative and in the case of mobile phones I'm sure many would argue is their battery lives.

I recently wrote a post on the best tactics you could employ to preserve your battery life within any battery-powered device. These tactics included both methods for long term and short term preservation. Following on from this, with so much money being invested into developing the best smartphone by all the large players such as Samsung, Apple, HTC, LG and Nokia, I wanted to explore who was winning the race. Specifically, I'm going to look into who is throwing the most tech into their devices and ultimately providing a powerful enough battery to power it for the longest.


Personally, I think the iPhone 6 is a beautiful looking mobile phone with some great features, which are traditionally Apple's trademarks. The Samsung Galaxy S6 Edge is the newest, most futuristic device available on the market with its curved screen, bound to make anyone considering buying it excited. The HTC M9, similar to the iPhone 6, is aesthetically beautiful and finished with a premium quality making it a worthy opponent of the two afore mentioned market leaders.

Before the battle begins though, the way I'll be judging these titans within the mobile world is on their battery power, battery life expectancy and overall ability to power the tech they support.

From the above it appears as if this battle has been won, but who in your mind conquered all? A quick digest of the tech within each handset shows that the Samsung Galaxy S6 Edge comes out on top. The Galaxy’s screen provides the highest resolution and is big enough to mount on your wall and watch a movie on (obviously joking), but the resolution far surpasses that of its rivals.

HTC One M9's camera vs Samsung Galaxy S6 Edges cameraWhile the HTC One M9’s back camera beats all with its 20 megapixel capacity, the 1 megapixel front facing camera reduces its flexibility for good photos from both sides of the phone, making the Samsung the best all rounder in terms of cameras as well. The video cameras are equal across all handsets and prove a difficult choice if your main requirement is video.

Apples iPhone has a different operating system which they claim to be smoother than android. This is their justification for a lower RAM within its phone. The two android devices both have 3GBs of RAM. Therefore computing power and operating system is negligible between the three, meaning the winner will largely be defined by your own personal preference.

Google Photos App available on Android and iOS handsetsMemory is important too and with so many photos, videos and music being stored on phones today, it’s always important to have more. But, what interests me is that whilst the iPhone 6 and Samsung Galaxy S6 Edge do not have expandable memory, Google has released their Photos App that provides unlimited storage within the cloud. I personally would prefer to have a cheaper version of the Samsung or iPhone and have my pictures backed up on the cloud, rather than the HTC with up to 128GB of storage and potentially lose all my photos if my phone was lost or stolen.


Apple iPhone is slimmer in comparison to Samsung's Galaxy and HTC's M9The weight and size of the devices again is negligible with the HTC being the tallest (by 2mm), the thickest (by 2mm) and the heaviest by (by 25 grams). Unless you have tiny hands and the strength of a newt, you wont struggle with either phone. If you do have small hands either hold on tight with both or buy a smaller phone which doesn’t pose the threat of being dropped or being thumb-unreachable.

Connectivity is a big one here, because whilst your battery is powering your device you need to know you are going to have the best chance of receiving calls otherwise your battery is working extra hard to try and search for signal. The Samsung Galaxy S6 Edge was awarded the ‘Telstra Blue Tick’ (signifying that the handset is suitable for use in regional parts of Australia), which to me is very important. What is the point in owning a fancy / expensive smartphone if you cant do the basics such as receive calls and texts within the unforgiving rural areas of Oz?

Samsung Galaxy S6 Edge Finally the battery life, that important element of any handset, which keeps us connected to the outside world. The HTC wins by offering up to 21 hours of 2G talk time, with the Samsung coming in at 18 hours. This is great if you plan on calling someone for this amount of time, but that’s highly unlikely unless you’re a love-struck teenager. Therefore the standby time in my opinion is the most important factor because it determines how long your phone can stay on and remain available for you to receive and send communication. Samsung weighs in at a whopping 20 days standby time (almost 3 weeks), with the HTC falling short at just over 16 days (2 weeks and 2 days). Both handsets put the iPhone to shame with its dismal 10-day performance figures.

Samsung Galaxy S6 Edge Wireless ChargingThis is why in my opinion the Samsung Galaxy S6 Edge reigns supreme overall. It has superior tech specs such as the screen, cameras and processors coupled with the Telstra Blue Tick for coverage. All of this plus a futuristic curved screen and the phone still manages to stay powered on for longer is why I would choose the Samsung device over all others.
