Initial independent iPhone 13-series battery capacity findings hint at gains of up to 18.5% over the previous generation

A regulator has now added official battery ratings for each member of the new iPhone 13 flagship series to its database. These stats indicate that the devices have improved in terms of the important metric in question by at least 11% per variant compared to their respective predecessors. The results might make Apple's claims of increased screen-on time in this generation a reality.

ChemTrec is a US-based body that describes itself as "the definitive resource and solutions provider for hazardous materials and dangerous goods response". To this end, it generates and maintains databases of documents such as material safety data sheets for hazardous or potentially hazardous goods and compounds - batteries for electronics included.

Such information is found on ChemTrec's Apple & Beats Product Information Sheet, which has just been updated with information on the iPhone 13 series. It details the watt-hour (Wh) rating for all vanilla and Pro variants of this line - whereas Apple does not.

The Cupertino giant traditionally remains remarkably vague on its own official spec sheets for products such as iPhones. However, these figures are now officially out there for the first time, revealing that the Mini has a 9.57Wh battery, whereas that of the base model is 12.41Wh.

The 13 Pro has an 11.97Wh power-pack, whereas that of the Pro Max is now definitely the biggest of the bunch at 16.75Wh. This means that the 13 Pro and Mini have seen the smallest increases over their predecessors in this respect, with a capacity that has grown about 11% and 11.6% year-on-year respectively.

The iPhone 13, on the other hand, has a battery capacity of 15% more compared to the 12, whereas that of the 13 Pro Max has improved by 18.5% compared to its 12-series counterpart. Therefore, testing Apple's claims of up to 2.5 hours of extra use in its newest iPhones compared to the 2020 models will now be all the more interesting.

I became a professional writer and editor shortly after graduation. My degrees are in biomedical sciences; however, they led to some experience in the biotech area, which convinced me of its potential to revolutionize our health, environment and lives in general. This developed into an all-consuming interest in more aspects of tech over time: I can never write enough on the latest electronics, gadgets and innovations. My other interests include imaging, astronomy, and streaming all the things. Oh, and coffee.
