Here's why Apple's upcoming iPhone 13 series could feature great battery life

Unlike the current iPhone 12 models, a new report suggests that the next generation of iPhone 13 variants could ship with larger battery capacities.

When Apple launched its iPhone 12 series last year, it brought along several improvements including a more durable screen, 5G connectivity, plus OLED screens for the entry-level iPhone 12 mini and iPhone 12 models. It looks like the upcoming iPhone 13 series will bring a notable improvement in an area most users care about – battery life.

Apple actually reduced the size of the iPhone 12's battery last year, and several users complained that the battery life has been less than optimal. This is likely due to the addition of 5G connectivity, which is believed to cause additional battery drain compared to older networks. However, Mashable reports that newly leaked battery capacity figures suggest that the next iPhone 13 series could sport larger batteries.

While the iPhone 12 last year reportedly has a 2,227mAh battery, the report suggests that the iPhone 13 mini will have a larger 2,406mAh battery this year. Similarly, the iPhone 13 and iPhone 13 Pro are expected to sport a larger 3,095mAh battery versus the smaller 2,815mAh battery on their predecessors. Finally, the iPhone 13 Pro Max is expected to come with a 4,352mAh battery instead of the smaller 3,687mAh battery on its predecessor.

It has also been reported that the newer iPhone 13 series might support mmWave 5G support for blazing-fast download speeds in countries outside the US -- at the moment, the iPhone 12 series sold in other countries only include Sub-6GHz support for 5G networks.

The upcoming iPhone 13 models are also expected to feature screens with high-refresh rates, along with a much smaller notch thanks to a redesigned speaker grille at the top of the screen. We should see these devices arrive around October this year, while Apple's WWDC event will take place on June 7.
