The Best iPhones for battery life ranked [2021]

Is it really worth upgrading to the iPhone 12 for the battery?

So it’s that time of year again, when technology seems to take yet another leap  some call it “techtober” - but really it’s the annual release of Apple’s latest iPhone. This year, more so than previous there seems to be some  extra buzz around the iPhone 12 launch perhaps this is due to COVID-19 and we’re just craving something new. Despite the improved manufacturing  steps that Apple has implemented to reduce waste, such as removing the power plugs and earphones from the unboxing experience (which we think is great)) we’re still left wondering  Do we really need to upgrade?

We’ve already reached peak smartphone 

We all know that we have reached peak smartphones. The innovation curve has flattened a lot in the last few years and incremental design and feature benefits are all we can expect now. However, under the hood/ behind the scenes Apple is packing some serious punch with their new chips - the power and capability of which is phenomenal, especially with the iPhone 12.. In fact, every model from the last 3-5 years has been pretty incredible, but the iPhone 11pro and the iPhone 12 pro truly are next level devices, packing near computer power in only around 6-inches of a metal box. 

The current selection of Apple iPhones available offers  something for everyone, the standard iPhone 11 range, the iPhone XR and the 2020 iPhone SE are a line up of incredible phones catering for a wide range of budgets. If you want to save even more,  there are plenty of refurbished devices available to buy. 

How does the battery life compare between models?

In years gone by it was all about the camera, how good it was - whether or not it had portrait mode or a good front camera to you could take selfies with your family or the dog.  biggest   Nowadays  pretty much every iPhone in the current range has a pretty remarkable camera, so the focus has shifted to the battery life. 

We love nothing more than to research the specifications and performance of new devices when they’re released, but really it’s best to let the pros do it properly and give us a good idea of whether or not a device is worth the extra money. Enter MrWhosTheBoss
