Watch OnePlus 10T, iQOO 9T, OPPO Reno8, and Google Pixel 6a battle each other for the best battery crown.

  • OnePlus 10T, iQOO 9T, OPPO Reno8, and Google Pixel 6a go up against each other in a battery drain test.
  • The OnePlus 10T has the highest battery capacity among the lot, while the Pixel 6a has the smallest. 
  • All smartphones managed to last above six hours of screen on time.

The Rs sub-50,000 smartphone range is where we usually see flagship smartphones with top-in-line specifications. The OnePlus 10T, iQOO 9T, OPPO Reno8, and Google Pixel 6a are some of the latest smartphones in this price range. While these handsets give you excellent performance, as witnessed in our review of each, their battery life tells an entirely different story than you’d expected.

The OnePlus 10T has a 4,800mAh battery (the highest among these devices), iQOO 9T features a 4,700mAh battery, OPPO Reno8 comes with a 4,500mAh battery capacity, and Google Pixel 6a packs a 4,410mAh battery (the weakest among these handsets). The OnePlus 10T and OPPO Reno8 flaunt a 10-bit screen, while the iQOO 9T and Google Pixel 6a ship with an 8-bit panel. Folks at MySmartPrice did battery drain and charging tests on these smartphones, with each device set at a maximum brightness level and performing the same tasks to keep the test apples to apples. Here’re the results:

The battery drain test starts with video playback and speaker tests for two hours. This resulted in OPPO Reno8 at an 80 percent battery, iQOO 9T at 83 percent, OnePlus 10T at 86 percent, and Google Pixel 6a with an 87 battery in the tank.

The next round was a benchmark test where these devices went through Geekbench, AnTuTu, storage speed, and CPU throttling tests. These tests took an hour, and after three hours of usage in total, the OPPO Reno8 was behind others with 57 percent battery, followed by the iQOO 9T with 58 percent battery, and the OnePlus 10T and Google 6a with 64 percent and 67 percent battery, respectively.

Next, these handsets were in for a gaming test, and the game used for the test was Call of Duty Mobile. After an hour of heavy gaming, the OPPO Reno 8 was at 39 percent battery left, the iQOO 9T at 41 percent battery, and the OnePlus 10T and Google Pixel 6a were both at 47 percent.

These devices then went through a quick round of a video recording test for 30 minutes. The OnePlus 10T came out with a 38 percent battery in the tank, followed by the Google Pixel 6a with 36 percent battery, the iQOO 9T at 32 percent battery, and OPPO Reno8 about to head into the red zone with 24 percent battery.

For the final round, these phones spent two hours on social media. With 6 hours and 19 minutes of screen time, the OPPO Reno8 was the first to getw out of the game. Next, the Google Pixel 6a ran out of juice at 6 hours and 42 minutes, followed by the iQOO 9T, which lasted a minute longer than the Google Pixel 6a. The OnePlus 10T took the crown with 6 hours and 53 minutes of battery life.

Once all phones were out of power, MySmartPrice does a quick charging test on them. The OnePlus 10T supports 150W, iQOO 9T 120W, OPPO Reno8 80W, and Google Pixel 6a 18W charging. The OnePlus 10T and iQOO 9T did well and were fully charged in 24 minutes, and OPPO Reno8 took 36 minutes to reach 100 percent battery level. The slow and steady Google Pixel 6a took around 2 hours to refuel fully, 1 hour and 55 minutes, to be precise.
