Battery life

UMIDIGI A3 is equipped with a 3300 mAh battery paired with a 5V/1A charger. We've purchased the smartphone from the UK, so the charger has a Uk plug. If you buy it from a Chinese or European shop, it will arrive with a standard European union plug.

It took our review unit ii hours and 58 minutes to charge the 3300 mAh battery from 0% to 100% with the included 5V/1A charger and cable. The charging speed is almost steady with a minor slowing downward later on the bombardment reaches l% of its chapters, which happens in 1 hour and 20 minutes from the start. It takes another 40 minutes for the battery to reach 80% of its capacity and the last 20% need 48 minutes to complete. The battery temperature starts at 24°C and gradually increases to 29°C during the first 1 hour and 10 minutes. Later that, information technology makes a superlative and goes up to 34°C for a few moments earlier gradually dropping downwards to 38°C at the end.

Our review shows a browsing battery life of half dozen hours and 53 minutes. The discharging process is tedious for the starting time xx minutes and for the last 15 minutes. In between, information technology goes at a steady pace. The battery temperature starts at 31°C and in 50 minutes reaches 37°C. It remains at that level for two hours and 24 minutes, and drops to 36°C later that, maintaining a fluctuation from 36°C to 37°C and back until the end.

The video test for battery life uses a 1080p video at 30 fps with a ~20Mbps charge per unit is used. Our review unit's score from this examination is 11 hours. The discharging process starts slow and ends ho-hum, while in between it maintains a steady footstep. The bombardment temperature starts at 26°C and in i hour reaches 33°C remaining at this level most for four hours. After that, it drops a notch to 31°C-32°C fluctuating around this level until the end.

For the 3D Graphics/Gaming test, the YEBIS OpenGL ES 3.0 3D Tech Demo is used. The bombardment of our review unit lasted for 6 hours and 29 minutes. The discharging process follows the same linear pattern observed from the previous two tests. The battery temperature starts at 27°C and reaches 37°C in 45 minutes. It remains at this level until the stop with occasional jumps to 38°C.
