The battery life of Samsung‘s Galaxy S23 Ultra has been insanely good from day one. During our review of the phone, we could get almost ten hours of screen-on time on a single charge. Over the past one and a half month, it has only got better in battery management. And that has been validated by DXOMARK. The publication recently put the Galaxy S23 Ultra through its rigorous battery test suite and the device came out with flying colors. The new Samsung flagship offered the best battery performance of any premium Android smartphone or iPhone ever.
Galaxy S23 Ultra’s battery performance is undefeated in the premium segment
During their testing, DXOMARK found that the 5,000mAh battery inside the Galaxy S23 Ultra could keep the phone running for up to two days and 19 hours on a single charge on moderate usage. The phone lost less than two percent of battery charger per night on average. It charged from 0 to 100 percent in one hour and 21 minutes (two hours and 18 minutes on wireless charging), while a 0 to 80 percent charge took 37 minutes. Just five minutes of charging was enough to keep the phone on for more than five hours.
The only notable problem that DXOMARK found on the Galaxy S23 Ultra is the battery level collapsing as soon as it reaches five percent. This is something users need to be wary of. The publication also noted that the phone’s battery consumption when using the camera or listening to music is slightly on the higher side than average. High residual consumption of the wireless stand is another con, but that’s nothing major.
Overall, the Galaxy S23 Ultra achieved a score of 142 in DXOMARK’s battery test. It leapfrogged the Asus ROG Phone 6 (140) to sit atop the chart for premium models. The latter is a dedicated gaming smartphone with a massive 6000mAh battery. Apple’s iPhone 13 Pro Max is in the third spot with a score of 136. The 2021 maxed-out iPhone model has a 4352mAh battery. Its successor iPhone 14 Pro Max also packs an identical 4323mAh battery but could only achieve a score of 133 to sit in the fourth spot. The iPhone 14 Plus makes up the top five.
The latest Samsung flagship leaves the 2022 model in the dust
What makes the Galaxy S23 Ultra’s battery life more special is the improvement over its predecessor. DXOMARK placed the Galaxy S22 Ultra in the 17th spot in its chart with a score of just 103. Samsung switching to TSMC-made Snapdragon 8 Gen 2 processor for the latest flagship made the difference this year. The Snapdragon 8 Gen 1 powering the 2022 models in the US (used in the DXOMARK test) was manufactured by the Korean brand. Qualcomm switched to TSMC for the new chips because of power-efficiency issues with Samsung’s fabrication process.
In the all-time global list, which also includes budget and mid-range models, the Galaxy S23 Ultra’s score of 142 puts it in the sixth spot. Honor’s Magic 5 Lite 5G tops the chart with a score of 152. You can find DXOMARK’s detailed battery test report for the latest Samsung flagship here.
