Battery life is a key issue when shopping for a brand new iPhone or any new smartphone, as is battery well being. A technique or one other, iPhone battery life has been a scorching subject prior to now few weeks, and we’re about to take a look at one other rumor teasing improvements that can assist Apple lengthen battery life in future fashions. However this one is a seemingly boring report detailing inside iPhone adjustments that almost all consumers received’t care about.

Apple is reportedly engaged on an enormous change for the logic boards it makes use of contained in the iPhone that can let it release further area for bigger batteries. That’s thrilling, contemplating what has been taking place with iPhones not too long ago.

First, some iPhone 14 Professional house owners complained their batteries degraded sooner than earlier fashions. Apple by no means actually addressed the difficulty, and it seems that it’s not an actual downside.

Then, the iPhone 15 got here out, and we found the Professional variants get the identical battery life estimates as their predecessors. Meaning the iPhone 15 Professional Max has wonderful battery life and can outlast the Galaxy S23 Extremely in real-life utilization. However, extra curiously, the iPhone 15 Plus has even higher battery life than its costlier sibling.

Lastly, the iPhone 15 Professional and 15 Professional Max began overheating, together with cases whereas the handsets have been charging. That’s one other problem that may influence the battery, however one which Apple has principally mounted.

Nicely-known analyst Ming-Chi Kuo penned a brand new weblog put up the place he detailed a brand new resin-coated copper (RCC) materials for logic boards. Right here’s how he described it:

RCC can scale back the thickness of the mainboard (i.e., it may save inside area) and make the drilling course of simpler as a result of it’s fiberglass-free. Nevertheless, RCC is not going to be adopted within the 2024 iPhone 16 attributable to its fragile traits and incapacity to go drop exams.

Kuo mentioned that if Apple can enhance RCC earlier than the third quarter of 2024, the iPhone 17 Professional fashions may use it.

The iPhone 15 Professional signifies that Apple might need hit a wall in the case of enhancing battery life. The Professional fashions characteristic the extra environment friendly A17 Professional chip, which reduces energy consumption. Additionally, the telephones are 0.4 mm thicker than their predecessors. However the iPhone 15 Professional/Max estimates are the identical because the iPhone 14 Professional/Max.

A technique to enhance battery dimension is to extend the general dimension of the iPhone. And Apple will reportedly improve the scale of the iPhone 16 Professional fashions subsequent 12 months. The principle motive it’s doing that’s apparently to accommodate a zoom lens contained in the smaller mannequin.

One other strategy to increase battery life is to alter the battery expertise. Rumors say iPhone 16 fashions may embrace new stacked battery designs. Adopting RCC to additional scale back the thickness of the mainboard can be one other strategy to improve the inner area obtainable to the battery.

A mixture of the concepts above may assist Apple increase iPhone battery life within the coming years. None of those iPhone improvements are confirmed, nevertheless.

I speculate {that a} smaller logic board would permit Apple to make use of higher cooling strategies in future iPhones. The iPhone 15 Professional overheating problem means that that is one thing Apple has to repair on the {hardware} degree.
