A couple of the world’s best smartphones go head to head as the Apple iPhone 7 Plus takes on the new Samsung Galaxy S8 Plus in a battery performance showdown. The iOS handset has the biggest iPhone battery yet while the new Galaxy S series addition packs in less power than its predecessor. Read on and find out which phone lasts longer.

Samsung Galaxy S8 Plus - Battery specs and features

The 6.2-inch Samsung handset houses a 3,500 mAh non-removable lithium ion cell. Despite the robust battery, though, the S8 Plus is only able to last a whole day with moderate use. It can extend for a little longer, but the phone must be under certain settings – like reduced brightness, lowered resolution and/or a turned off Always-On Display option – for that to happen.

According to Trusted Reviews, native video watching with the Video Enhancer turned on eats through the phone’s battery rather quickly. The new Galaxy handset may need to be charged every night, although customisation and battery-saving modes do a good job of extending battery life.

Just like its predecessor, the S8 Plus makes use of the South Korean tech titan’s own Adaptive Charging instead of Qualcomm’s Quick Charge. It takes the phone an hour and 40 minutes to be fully charged from zero. Wireless charging support is available, although it extends charging time by another half hour.

The latest 5.5-inch iPhone is powered by a 2,900 mAh non-removable lithium ion battery, which is able to provide up to 21 hours of phone calls and 60 hours of music playback. With moderate use, the Apple flagship can last up to two days before wearing out. Compared to previous iPhone models, the 7 Plus lasts significantly longer thanks to the latest energy-efficient A10 Fusion chipset inside.

Unfortunately for users that are into wireless charging, the Apple handset has no such feature. The 7 Plus also has no fast charging support. The smartphone can take more than three hours to reach 100 percent battery level from zero.

Samsung Galaxy S8 Plus vs Apple iPhone 7 Plus – Battery performance test

When TechRadar put the new Galaxy smartphone in a chain of rigorous battery performance tests that included 90 minutes each of web browsing, gaming, YouTube playback and native video watching, the Samsung handset did a great job. After six hours of work, the S8 Plus still had 18 percent battery life.

The iPhone 7 Plus, on the other hand, didn’t even complete the third task when it experienced the same undertaking. The Apple flagship was thoroughly exhausted before the gaming test was done and finished with a total performance time of four hours and 20 minutes.
