iPhone 15 battery capacities have improved, reveals China regulator

Apple's new iPhone 15 Pro range

Last updated

New details revealed in a regulatory filing say that the iPhone 15 Pro Pro and iPhone 15 Pro Max have slightly larger batteries than their predecessors.

Apple has made claims for the battery life in its new iPhone 15 range, but it never specifies any details. Now full details of the battery sizes and capacities for the range have been spotted by MySmartPrice in a Chinese regulatory filing.

It had been rumored that the iPhone 15 range would get a substantially improved battery life — and use longer-lasting stacked batteries.. However, according to the filing, the breakdown of iPhone model and battery capacity is:

  • iPhone 15: 3,349mAh, 12.981Wh
  • iPhone 15 Plus: 4,383mAh, 16.950Wh
  • iPhone 15 Pro: 3,274mAh, 12.70Wh
  • iPhone 15 Pro Max: 4,422mAh, 17.109Wh

Each of these figures is slightly higher than that of the equivalent model in the iPhone 14 range. Those were:

  • iPhone 14: 3,279mAh
  • iPhone 14 Plus: 4,325mAh
  • iPhone 14 Pro: 3,200mAh
  • iPhone 14 Pro Max: 4,323mAh

Apple's iPhone 15 range will be available to pre-order later today, with prices staying the same as for the iPhone 14 range.

I guess that’s a good thing, though at those capacities and the variance you’re not going to see any difference. Capacity varies by plus or -5% on most of these lithium batteries.  You’ll see a bigger difference just from having a new battery. My 14 promax is already down to about 80% to 85% capacity.

3nm A17 Pro will also contribute to longer battery life.

FWIW (and I’m not an expert), but I suspect the reports of the iPhone 14 Pro and Pro Max batteries draining faster than expected could be down to two factors:

1. Smartphone addiction is very visibly getting worse. The new capabilities of the 14 class meant people who already spent too much time on their smartphone spent even more time on it, meaning they have to recharge it more, thus causing more (natural) decay in capacity, perhaps not being fully conscious of how much more they were using it.

2. That said, there’s too many reports to dismiss it as just that. I think perhaps some or all of the larger Pro Max batteries in particular have a defect that causes them to “age” faster than those in earlier models. Apple doesn’t like to say anything about flaws until they have thoroughly investigated and know for certain that there’s a real problem, so that’s likely why the company hasn’t issued a statement.

I’m predicting that sometime next year, Apple will identify the problem and offer a cheap battery-replacement option for 14 owners, as they did for the 6/6s.

So the regular Pro has the smallest capacity of all of them??
