Battery Tests

Oukitel WP27 packs an 8500 mAh Li-Pol battery with 33W fast charging support. It arrives with a 33W USB-C charger in the box and a USB-C to USB-C cable. All battery tests we run on the devices we review are developed by us and performed with the screen of the device calibrated to 200 cd/m2. Battery-saving features are disabled. We've tested an identical or similar combination of a display, refresh rate, chipset, and battery, so we've built a good base for making comparisons. All test results and comparisons are below.
Charging (2 hours and 22 minutes)
The battery of our WP27 was charged in full for 2 hours and 22 minutes with the provided USB data cable and charger. The charging process is fastest from the start until the battery regains 35% of its charge - that's 27 minutes from the start. Afterward, it slows down a bit and maintains a steady speed until the battery regains 80% of its charge. This second stage takes 40 minutes. The final stage is the longest and replenishes the last 20% to 100%. It takes 1 hour and 15 minutes. The battery temperature starts at 23°C and in a minute jumps to 33°C. Afterward, it gradually increases to 42-43°C and remains at this level for 45 minutes. At the end of this stage, the battery temperature begins decerasing and measures 24°C in the end.
Browsing at 60 Hz (21 hours and 58 minutes)
During our intensive browsing test, the battery of our WP27 lasted for 21 hours and 58 minutes which is a pretty good result. The discharging process draws a steady line from the start until the end. The battery temperature starts at 24°C. Reaches 29°C in 1 hour and a half and stays at this level until the end.
Browsing at 120 Hz (17 hours and 20 minutes)
During our intensive browsing test but with the screen's refresh rate set to 120Hz, the battery of our WP27 lasted for 17 hours and 20 minutes. The discharging process follows almost exactly the pattern of the 60hz browsing test. The battery temperature starts at 24°C. Reaches 21°C in 1 hour and a half and stays at this level almost until the end - an hour before the end, the temperature drops to 29°C.
1080p Video at 60 Hz (24 hours and 44 minutes)
1920x1080, 30 fps, H.264, 20Mbps bitrate
The video test for battery life uses a 1080p video at 30 fps with a ~20Mbps rate is used. Our review unit's score is 24 hours and 44 minutes - another excellent result. The discharging process follows the same pattern observed during the 60Hz browsing test. The battery temperature starts 26°C level, increases to 28°C after 40 minutes, and stays at this level almost until the end, when for a short period it measures 29°C.
2160p Video at 60 Hz (21 hours and 1 minute)
3840x2160, 30 fps, H.264, ~55 Mbps bitrate
The 4K video battery life test uses a 2160p video at 30 fps with a ~55 Mbps rate. In this test, the battery of Oukitel WP27 lasted for 21 hours and 1 minute. The discharging process curve is the same as the ones of the previous tests. The battery temperature starts at 27°C and increases to 29-30°C maintaining this level until the end.
3D Graphics/Gaming 60 Hz (12 hours and 45 minutes)
YEBIS OpenGL ES 3.0 3D Tech Demo
For the 3D Graphics/Gaming test, the YEBIS OpenGL ES 3.0 3D Tech Demo is used. The result from this test is 12 hours and 45 minutes. The discharging process curve does not offer any surprises and is almost without change from the start until the end. The battery temperature starts at 24°C, reaches 33°C in half an hour, and after another hour goes a notch up to 34°C, remaining at this level until the end.

Infrared thermography
The above photos of the Oukitel WP27 are taken with a FLIR thermal camera. The left photo shows the device's temperature during charging. The hottest part during this process is the top left area of the device with a temperature of 24.6°C. The second photo depicts the device's temperature during our 3D battery life test. In this case, the hottest part is the center of the chin with a temperature of 31.1°C. The other point of reference is the top right area of the device with a temperature of 29.1°C.

Battery Settings

The Battery menu contains the usual elements while preserving Oukitel's design of the system menus. The first element is the battery status followed by the Battery Usage date. Then you get the Battery Saver toggle that can be activated manually or scheduled. It can also automatically switch off when the battery's charge goes above 90%. You can also schedule it to turn automatically on when the battery drops to a certain percentage that you choose. The Adaptive Battery detects apps that are draining the battery significantly and issues a notification with the option for you to restrict those apps. You can always toggle off this option. Finally, there's the battery percentage toggle that displays/hides the charge level in the battery icon on the status bar.
