Battery marathon: ZenFone Max vs iPhone 6s Plus


The ASUS ZenFone3 Max (ZC553KL) is an absolute workhorse, capable of outlasting even the most premium phones out there with its massive 4100mAh battery. Here’s a quick rundown of how that translates into day-to-day usage when compared to what’s offered by the ASUS ZenFone 3 Max.

ASUS ZenFone 3 Max

Standby: 38 days

3G talk time: 17 hours

Wi-Fi web browsing: 19 hours

Audio playback: 72 hours

iPhone 6s Plus

Standby: 16 days

3G talk time: 24 hours

Wi-Fi web browsing: 12 hours

An incredibly energy-efficient Qualcomm Snapdragon 410 processor helps achieve this, but the ZenFone Max comes with plenty of apps to help conserve battery life too. Auto-Start Manager stops apps from running in the background, consuming system resources, and ultimately preventing unneeded battery drain. Power Manager intelligently monitors the ZenFone Zoom’s battery state, and can dynamically change settings to conserve power as needed.

The extra power offered by the ZenFone 3 Max makes it a prime candidate for charging other phones thanks to USB on-the-go. The included adapter allows a microUSB cable connects both phones, so one can charge using the ZenFone Max’s generous battery.

There’s a lot more to the ZenFone 3 Max than its amazing battery, though. Visit for a closer look.
