Naturally, larger batteries come on the expense of portability – however that hasn’t stopped one Reddit person from trying to reply the query: what would occur should you strapped an infinite energy pack to the rear of an inexpensive smartphone? 

As noticed by 9to5Google (opens in new tab), Redditor u/Downtown_Cranberry44 (opens in new tab) has carried out some DIY wizardry to efficiently connect a working 30,000mAh battery to their Samsung Galaxy A32 5G. Sure, you learn that proper – a 30,000mAh battery. For context, that’s six instances the dimensions of the Galaxy A32 5G’s authentic 5,000mAh battery, which already yields round two days of average use.

The larger concern, although, is one among security. As 9to5Google notes, energy packs of this measurement are extra susceptible to leakage and exterior injury; there’s a purpose you’ll be able to’t board a flight with batteries any bigger than 27,000mAh beneath present US legislation. 

For now, then, this form of at-home experimentation is nothing greater than that – we don’t count on to see Apple including a large batteries to the rear of the iPhone 15, for example. However experiments like this can assist us to understand simply how a lot intelligent engineering goes into the neat packaging of c. 5,000mAh batteries in right now’s smartphones.

By way of the telephones that provide the longest-lasting batteries in 2023, you’ll get round 16 hours from the Asus ROG Cellphone 6, and simply over 13 hours from each the just lately launched Samsung Galaxy S23 Extremely and iPhone 14 Professional Max.
