Display – Apple gave its fan base something new in the form of the 3D touch, but the size and resolution has been retained. The iPhone 6S comes with a 4.7 inch display with a resolution of 750 X 1334 pixels. Apple has never done anything conventional, which is why even its resolution is something you don’t find in most devices. Every new iPhone is compared first to its predecessor , so , if I was to follow the same format, I would say that the iPhone 6S delivers deeper blacks than the iPhone 6, and also churns out a better contrast than its predecessor . The Sunlight legibility however, is slightly lower than the 6 on paper, but the difference is so fine, that an average user will not make out the difference. Overall, the display on the iPhone 6S is good , when it comes to Apple’s standards, but when it comes to comparing the iPhone 6S to the other flagships in the field, I am afraid its pretty badly outgunned.

Battery – When it comes to the battery life of its devices, Apple has maintained their own stand yet again by fitting in relatively low rated batteries on the pretext that, the sort of technology that goes into the device, is light enough to be supported by the said battery. In truth, while 70 % of Apple’s claims are true, its the 30 % that concerns me.People need their smartphones to run through the day without having to charge it every now and then, and when they see that their device is not able to deliver on that point, they immediately opt for a device that can. Now, I am a believer in the fact that iOS is a pretty light OS, but the fact that you are getting a 1715 mAh battery just doesn’t cut it. Anyway, talking in numbers, we have 10 hours of 3G or video playback on a single charge , while Apple claims you can browse over WiFi for half a day. Overall, the battery could have been bumped up in my opinion, as 10 hours just doesn’t seem good enough these days, while just half a day of WiFi would drive many people crazy.

Battery capacity is lower compared to iPhone 6

Performance – Apple is never completely transparent about their performance benchmarks and features, so I will be working with whatever information they have put out to the public. So basically, the iPhone 6S is powered by the all nw Apple A9 chipset, which features a Dual core 1.85 GHz Typhoon processor, and a PowerVR GT7600 six core GPU. This package is complemented by 2GB of on board RAM which takes care of the Multi-Tasking department. Now, while there is a lot of speculation about who really manufactures the A9 chipsets, popular belief is that the Apple A9 is made by either Samsung, using the 14 nm process, or TSMC on a 16 nm process.Whatever the case maybe, the new Apple A9 has produced segment topping benchmark results, making the chipset, the best in the market today, overshadowing even the famed Samsung Galaxy S6 and the LG G4.When it comes to gaming, Android features OpenGL ES 3.1, while Apple has Metal. The speciality of both the aforementioned technologies is that they allow games to make full use of the built in GPUs, but when the two were pit against each other, it was Apple’s Metal that came out the undisputed winner.All in all, the iPhone 6S is a total rocker when it comes to the performance , so for all those performance junkies out there, this is the phone to have right now.

Camera – Finally, we have the camera. Now, on the onset, I was pretty disappointed to see an Autofocus camera on the iPhone 6S, while the OIS went into the 6S Plus, but that said, its still a pretty strong camera . Apple decided to bump up their camera resolution after long last, which is why in the iPhone 6S, the 8MP rear snapper has been replaced by the more capable 12 MP sensor, and while that too is a bit less compared to the smartphones in the market today, its something to build on for the Cupertino giants. But its not just the rear camera that got an upgrade. Apple decided to amp up the selfie power of the device, and so for the selfie lovers out there, the iPhone 6S plus comes in a more powerful and capable 5MP selfie snapper, which means, better and more pleasing selfies everywhere.When it comes to video recording, the iPhone 6S is all set . The new chipset, along with the 12 MO rear sensor, allows the phone to record 4K videos with ease, while also allowing Live Photos, a feature that captures 1.5 s video either side of the moment you hit the shutter, and saves it as a short animation.The Front camera has a few tricks up its sleeve as well. The 5MP snapper now supports HDR, and full HD 1080p capture. It also uses the display as a retina flash of sorts. In this, the screen goes white the moment you hit the shutter , with brightness 300 times the normal value. This mode helps you when you are shooting indoors or even up close.Overall, the camera package is a definite upgrade over the other iPhones of the past, but the performance could have been improved many folds, and I sure Apple looks into it for their next device.

All in all, we can clearly see that Apple had 3 points on their agenda while launching the iPhone 6S – Better display, more powerful performance, and a snappier camera. While the display wasn’t really a class topping aspect, the introduction of 3D touch, will definitely give users a lot to look forward to in the coming months.
The performance on the other hand has undergone a lot of tweaks here and there, and what we have in front of us is a segment topping beast , ready to attack whatever you may want to throw at it.
Lastly, the camera has definitely been improved over the other iPhones of the past, but there is still scope for a lot of improvement, and hopefully, we will see them implemented in the future.
