iPhone 13 Pro Max With Bigger Battery Could Rival Samsung S21 Ultra 5G

The iPhone 13’s rumored bigger battery might be a must.

Reports suggest the iPhone 13 will have both a beefier battery and 120Hz refresh rate — the latter delivering smoother scrolling and gaming.

With the 120Hz mode turned on, there’s more battery drain. And if you combine a 120Hz refresh rate with 5G (think: games) a battery upgrade for the iPhone 12 is practically a given — since 5G draws more power from the battery than 4G.

The way it stands now:

  • iPhone 12 Pro Max battery : 3,687 mAh
  • Samsung S21 Ultra battery: 5,000 mAh

An iPhone 13 Pro Max with a bigger battery would likely compete with the Samsung S21 Ultra and its 5,000 mAh (milliamp Hour) battery — which delivers long battery life even with 5G and 120Hz display mode enabled.

Other battery boosting tech may also be in store. The next-gen iPhone may use Qualcomm’s Snapdragon X60 5G modem which is a more power efficient design, possibly extending battery life.

The iPhone 13’s X60 modem would also be able to “aggregate 5G data from both mmWave and sub-6GHz bands simultaneously to achieve an optimal combination of high-speed and low-latency network coverage,” according to MacRumors.


A 5G connection via mmWave is generally faster than sub-6GHz 5G but mmWave operates over shorter distances than mmWave. In other words, longer-distance sub-6GHz and faster mmWave both have advantages depending on your location.


Note that the larger battery means the iPhone 13 will be slightly heavier, according to reports.
