Apple iPhone 14 - Can You Expect Any More From The Upgrade?

Updated: Oct 12, 2022

Having already tested the Battery Performance of previous Apple iPhones, we take a closer look at the Apple iPhone 14.

Apple has announced their latest devices iPhone 14 and iPhone 14 Plus launching on the 16th of September and 7th of October respectively, keeping with their tradition of promoting their latest devices in September for the October launch. It seems that Apple went all big this time with no replacement for the Mini versions.

At a glance:

  • Two sizes: iPhone 14 6.1” and iPhone 14 Plus 6.7”

  • New features: Satellite and Emergency Services

  • Crash Detection

  • Best Battery Life

The iPhone 14 and iPhone 14 Plus

At a first glance, the devices externally look like their predecessor iPhone 13 featuring flat edges and an aluminium cover with a glass back. In terms of pricing no major hikes there. The iPhone 14 will set you back £849 while the iPhone 14 Plus £949. The iPhone 14 Pro version is around £1,099.

One of the major changes for the US market is the eSim capability. Devices shipped in the US will no longer have a physical Sim slot. For Europe, we will still get the physical SIM slot.

We do see main changes in battery life, and this is one of the main focus points of Apple marketing. The iPhone 14 promises a longer battery than all previous models. Apple has been very good at optimising battery life and performance.

The iPhone 13 Pro has scored very highly in our battery performance testing. It obtained a ViserMark Battery Life of 2 Days of Use, impressive with a small battery capacity of 3100mAh.

The iPhone 13 Pro Max has lasted an impressive 3.5 Days of Use when assessed for ViserMark Battery Life within our strict testing protocol.

What Apple is managing very well is the Energy Efficiency of the devices.

The iPhone 13 Pro was given a Visermark rating of 2.5 out of 5 for Energy Efficiency.

The iPhone13 Pro Max increased its Visermark Energy Efficiency rating to 3.5. This was the highest Energy Efficiency rating record from our test results so far.

ViserMark is very much looking forward to completing the Battery Performance testing on the newly announced Apple iPhone 14 smartphones.

  • Will Apple smartphones continue to hold their hold on the Energy Efficiency Ratings?

  • Will the iPhone 14 achieve a higher Battery Performance Score - better than before?

Here at ViserMark, we will be keen to share with you our Battery Performance test results for the Apple iPhone 14 as soon as we have them available. In the meantime, take a look at our latest independent smartphone reviews and scores.


The latest released iPhone 14 devices have definitely improved performance and better cameras than their predecessors. Is this enough to make you trade in your previous device? You will have to judge if the cost versus the available features is worth the investment.

ViserMark is on a mission to help manufacturers improve the Energy Efficiency of their devices rather than simply increasing the battery capacity for longer battery life.
