Frequently Asked Questions
Which phone has better battery life?
The Sony Xperia Z5 generally offered better battery life than the Galaxy S6. The Z5’s larger battery capacity and Sony’s power-saving technologies, like Stamina mode, allowed it to last longer on a single charge, especially under moderate to heavy usage. The Galaxy S6, while capable, was often criticized for its relatively shorter battery endurance due to its power-hungry QHD display and less optimized battery.
Is the Galaxy S6 water-resistant?
No, the Samsung Galaxy S6 is not water-resistant. Unlike its predecessor, the Galaxy S5, Samsung opted to remove the water and dustproofing features in favor of a more premium unibody design with glass and metal. If water resistance is a primary concern, the Sony Xperia Z5 is the clear choice in this comparison as it features IP65 and IP68 ratings for water and dust protection.
Which phone has a better display for media consumption?
For media consumption, the Samsung Galaxy S6’s Super AMOLED display often edges out the Sony Xperia Z5. The S6’s QHD resolution provides sharper details, and the AMOLED technology delivers deeper blacks and more vibrant, saturated colors, making movies and photos pop.
