The latest mid-range phone from OnePlus, the OnePlus 13R, has impressed me with its exceptional battery life. In a recent test, I left the device alone for eight days and was shocked to find that it still had enough charge to function when I picked it up again.
This is not surprising given that the OnePlus 13R ranks high in our best phone battery life list, alongside other top devices like the OnePlus 13 and Pixel 8a. However, my hands-on experience confirms its impressive endurance.
I tested the device through a series of activities, including a 200-photo shootout with the Pixel 8a, to gauge its performance. After using it for about a week, I left it aside for an extended period and was surprised to find that it still had charge when I retrieved it eight days later.
This experiment provides valuable insight into the battery life of smartphones and complements our standard testing methods. When used normally, with moderate screen time, I estimate that users can probably go a day or so without recharging their OnePlus 13R.
Long-lasting devices are essential for many smartphone users, and 2025 is off to a great start in terms of battery performance. The latest smartphones from brands like OnePlus, Samsung, and others have demonstrated significant improvements in power management.
The combination of advanced chips, such as the Snapdragon 8 Elite system-on-chip used by the OnePlus 13R and Galaxy S25 Ultra, contributes to these impressive results. Even devices with last year’s top silicon, like the OnePlus 13R, benefit from improved power management techniques.
As more phones are tested in 2025, we can expect even better battery life results. For now, however, it appears that OnePlus is establishing itself as a leader in terms of long-lasting smartphones.
