Samsung Galaxy S10+ Exynos Review

Battery Tests

Samsung Galaxy S10+ is equipped with a 4100 mAh Li-Pol battery and is coupled with the same fast charger the previous generations had - a 5V/2A~9V/1.67A unit. The model supports 15W Qi/PMA wireless charging and 9W wireless reverse charging. The latter is enabled from the Wireless PowerShare feature found on the Quick Settings. All battery tests we run on the devices we review are developed by us and performed with the screen of the device being calibrated to 200 cd/m². The display is set to its maximum resolution - 1440 x 3040 pixels. It took only 1 hour and 32 minutes to charge the 4100 mAh battery of our review unit in full from 0% to 100%. For comparison, the 3500 mAh battery of the S9+ charged for 1 hour and 45 minutes despite it has the same fast charger as the S10+. The fast-paced charging speed is maintained for 1 hour and 9 minutes during which the battery regains 90% of its capacity. After that, charging slows down and the last 10% need 23 minutes to be completed. The battery temperature starts at 22°C and a minute later already measures 28°C. 25 minutes later, it reaches its peak of 38-39°C and stays there for 38 minutes. After that, the temperature starts decreasing until it reaches 28°C in the end. During our intensive browsing test, the battery of our review unit lasted for 10 hours and 32 minutes. The discharging process is quicker during the first 7 minutes but slows down a bit after that. It continues at the same speed until the battery drops to 20% of its capacity and slightly slows down again. The battery temperature starts at 28°C and in 40 minutes reaches 32°C stays at this level until the end. The video test for battery life uses a 1080p video at 30 fps with a ~20Mbps rate is used. Our review unit's score from this test is 16 hours and 26 minutes. The discharging process is faster for the first 5 minutes, after which it slows down a bit and maintains a steady pace until the end. The battery temperature starts at 26°C and after 5 minutes increases to 28°C maintaining this level until the end. The 4K video battery life test uses a 2160p video at 30 fps with a ~55 Mbps rate. In this test, the battery of the S10+ lasted for 13 hours and 24 minutes. The discharging process goes fast for the first 8 minutes but slows down a bit after that, keeping a steady pace until the battery drops to 3% of its capacity when it slows down a bit more. The battery temperature starts at 27°C and in 37 minutes it goes up to 31°C maintaining this level for 8 hours, after which, the temperature goes up to 32°C staying at that level until the end. For the 3D Graphics/Gaming test, the YEBIS OpenGL ES 3.0 3D Tech Demo is used. The battery of our review unit lasted for 4 hours and 24 minutes. The discharging process is a bit different from the one on the previous two tests. It develops at a steady pace from the start until the battery drops to 7% of its capacity. After that, it slows down a bit, but at 3% it goes on faster again. The battery temperature starts at 28°C and in 37 minutes reaches 40°C remaining at this level for 2 hours and 40 minutes. After that, it goes up to 41°C and stays at that level until the end. The above photos of our Galaxy S10+ review unit are taken with a FLIR thermal camera. In this particular case, they demonstrate that the S10 and the S10+ have identical hot areas with almost identical top temperatures in those areas. The left photo shows the device's temperature during charging. The hottest area, in this case, is in the upper left part of the body where the temperature measures 38.7°C. The second photo depicts the device's temperature during our 3D battery life test. In this case, the device gets warm in almost the same area but a bit lower. The peak temperature there is 42.8°C.

Battery Settings

The Battery settings can be found in the Device Care menu from the System Settings. From there you can get up-to-date information about the battery's status and usage data. You can also choose from four power modes. The default one is called Optimized and does not offer additional options. There's a High-Performance mode which retains the WQHD+ resolution and ups the brightness by 10+. Logically, with this mode on, the device consumes more power. There's a Medium power saving and a Maximum power saving mode as well. The medium one restricts background processes, turns off the AOD and lowers CPU speed. You can opt which of these features to be applied. This mode by default lowers the brightness by 10% and the screen resolution to FHD+. The maximum power saving mode does the same but the resolution is lowered to HD+. The additional battery settings contain a number of toggles for useful features such as notifications when an app running in the background draws too much power, adaptive battery, managing sleeping apps, etc.
