Apple is reportedly eyeing a major battery acclivity for its next iPhone — one that will not only boost the per - charge efficiency but also pave the agency for easier ( and hopefully cheaper ) repair . Ming - Chi Kuo , a well - have it away industry insider for Apple move and psychoanalyst at Tianfeng International Securities , writes in his late investornotethat Apple is make modifications to theiPhone 16 Pro Max’slithium - ion barrage fire that will increase the free energy density .
barrage fire density is defined as the amount of energy that can be hive away per volume , and it is usually assess in watt - hour per liter for an intermediate atomic number 3 - based battery , the variety used in smartphones . The benefit of a gamey - density barrage mean more electric energy can be put inside a pack , or conversely , the size of the battery can be shrunk without reducing the capacity .

bet on the materials used to produce a high - density electric battery , the welfare can also let in a longer lifespan , which means reduced need for quick replacement due to chemical degradation that happens with the born charge - discharge hertz . Notably , Kuo refer that if Apple is able-bodied to achieve mass production of thehigher - density battery for the iPhone 16 Pro Maxwithout any inherent outlet , it will be used across the entire iPhone 17 series set to arrive in 2025 .
While a gain in battery efficiency is a welcome move , specially considering the fact that most consumer value battery life as a essential argument before buying a phone , there is another welfare to Apple ’s approaching . A gamey - density shelling would also entail adjusting the core pattern , and in this case , it could be a repairability blessing borne out of technology necessity .
Theoretically , it sounds easy , but grant to this inquiry composition published in the journalEnergies , “ spotty temperature distribution conduce to non - uniform and accelerated abjection . ” In simple term , increasing the density without considering the temperature factor would affect a battery ’s life-time , which means an average smartphone exploiter will have to get a renewal preferably than usual .
To handle the heat issue uprise from a denser battery camp , Apple has reportedly decided to habituate a steel casing for the stamp battery pack for the first metre to ensure efficient heat profligacy . brand is also more resistant to chemical oxidation , so there ’s that extra welfare , too . And that make for us to the final fringe benefit from this shift .
“ The use of a stainless steel battery type also reduces the difficulty of move out the battery , which will aid Apple follow with the European Union ’s requisite for nomadic phone batteries ’ substitutability in the future , ” remark Kuo . As we explain in our article abouthow the EU want stamp battery to last long and be easy approachable to consumersto allow for easier remotion and replacement , Apple is reportedly preparing for that shift .
In a nutshell , the iPhone 16 Pro Max might not only deliver a hike in shelling life but could also ease the chore of taking out the battery . That ’s swell word for DIY enthusiasts , and it would make the task well-situated for fix experts and might also make for down the costs of avail such divine service . But do keep in mind that manufacturing high - density is a pricey endeavour and might lead to increased costs that could finally mean more expensive iPhones .
It is undecipherable how exactly Apple is increase bombardment density , but there are multiple methods to achieve it . Research suggests it could switch to using a more ion - dense electrode cloth , exchange the liquid electrolyte with solid table salt , or switch the solvent . Thispaper , published in the Highlights in Science , Engineering , and Technology journal , gives an overview of the excogitation proposal .
