Apple's iPhone 5s vs iPhone 6 vs iPhone 6s: Should I upgrade?

Apple launched the much-awaited iPhone 6s and iPhone 6s Plus phones at an event in California today. Featuring similar dimensions as the existing iPhone 6 and the 6 Plus, all that the new iPhones promised were new features, functionalities and specifications.

However, for existing iPhone users, the moot question is if the iPhone 6s is brilliant enough or advanced enough to warrant replacement. While last two versions of iPhones were good phones in their own merit, here are a few reasons why you should or should not upgrade.


The sole specification that has remained Apple's Achilles Heel since the first iPhone was launched is battery life. Has the iPhone 6s solved the riddle? The answer is a resounding no.

Amidst the two and a half hour session, Apple hardly made any mention of the iPhone 6s battery life. Going by available technical specifications, you'll have to make do with the same battery that powered the existing iPhone 6 and with new features like 4k video shooting, Live Photos and 3D Touch coming into play, it'll be tough going for the built-in lithium-ion battery. The absence of wireless charging feature complicates things further.

However, if you do need a great battery, upgrading to the iPhone 6s Plus will make more sense. The larger iPhone offers an extra week of standby time, ten extra hours of talk time and thirty extra hours of audio playback.

Design and build

Like most sources have been saying and what Apple confirmed today, the iPhone 6s and the 6s Plus won't bring in any new look or wow factor in terms of sizes. However, the new Rose Gold finish looks absolutely stunning, and an industry leading glass screen over the display will negate whatever remote chances you had of turning it to pieces.

However, I wouldn't be really tempted to go for an upgrade just for a stronger glass panel, but getting my hands on a Rose Gold iPhone is another thing.


While some industry sources predicted that the new iPhones may feature 32GB as base storage, iPhone 6s is coming with the same base storage as the existing iPhone 6 and the iPhone 5s at 16GB. However, the 128GB variant makes its first appearance for a non-Plus model and this should be rather enticing for iPhone 6 and the iPhone 5s users.


Display is one area that represents the large gulf between the iPhone 6 and the 6s. Even though resolution remains the same at 326ppi, the new Taptic Engine enables 3D Touch feature which lets you interact with the home screen and the apps through gesture control. Simple light and deep taps of your fingers lets you perform a range of functions like taking a selfie or sending a message.

While mastering this new technology may take a little time, the process is so simple and smooth that once you use it, getting back to older versions would feel like going back in time to perform basic operations.


The new A9 chip, despite being based on the same 64-bit architecture and embedded motion coprocessor like the A8 and the A7, offers 70 percent faster CPU and 90 percent faster GPU performance than the A8. The M9 coprocessor also runs features like Apple's HealthKit and Siri, thereby reducing excess burden from the A9's shoulders.

If you are a gamer or a quick multi-tasker, upgrading is a must.


While iPhone 6 carried the same camera as the 5s, iPhone 6s has now become Apple's first iPhone to break the 12MP barrier. The new 12MP iSight camera covers more pixels and features improved noise reduction, enhanced Panorama photography with 63MP coverage and improved local tone mapping over the existing camera.

The main difference, however, is video recording. The iPhone 6s can shoot 4k videos with 3840 by 2160p resolution compared to the previous two iPhones which can only shoot 1080p HD videos.

The front camera also features a major upgrade. The miniscule 1.2MP camera in the iPhone 6 makes way for the new 5MP FaceTime camera with Retina flash and Auto HDR for videos.

If you are in love with iOS and prefer sticking to iPhones, then the camera offers enough reasons for an upgrade.

4G Capability

If the iPhone 6 and the 5s didn't impress you much with their 4G capabilities, the iPhone 6s will come as a respite. The new iPhone carries 23 bands, the highest for any smartphone, and its advanced LTE capability is twice as fast as the iPhone 6.


The iPhone 6s comes as a highly capable smartphone which surprises as well as disappoints existing iPhone users in equal measure. While the new iPhone brings in no good news as far as battery life and design are concerned, it is far superior in terms of camera technology, LTE capability, processor speed and display functionality.

Even though iPhone 5s users have far more reasons for an upgrade than iPhone 6 users, the fact that sticking to a year-old technology when competitors are quickly catching up may not bode well for users who wish to keep their phones for long term usage.
