Equipped with a Snapdragon 820 processor, 6GB of RAM, and 64GB of UFS 2.0 storage, the OnePlus 3 delivers flagship performance. Yet, its 3000mAh battery often falls short of a full day for heavy users. In my initial days with the device, I needed two charges daily, including a late-night top-up, to keep going. A larger battery would have made this an even stronger flagship contender.
The silver lining? Dash Charge refills it from 0-100% in under an hour. Still, I'd rather optimize for longevity than rely on frequent charging. As a hands-on Android enthusiast who's tested these tweaks extensively on my OnePlus 3, here are three effective strategies to stretch battery life—all day long.
Note: These are based on real-world testing, not lab conditions, so results may vary.The OnePlus 3's HD Optical AMOLED display is inherently efficient compared to LCDs. Take it further with OxygenOS's built-in system-wide dark theme, found under Personalization in Settings. Pair it with custom accent colors for a sleek look.
AMOLED tech lights only non-black pixels, slashing power draw. Most modern apps now offer dark themes—enable them wherever possible.
Pro Tip: Check our guide on three more AMOLED battery-saving hacks; they apply here too.OxygenOS lets you wake the device or launch the camera via screen gestures, but these run background services that create wakelocks and drain battery. If you rarely use them, disable via Gestures in Settings—tap Disabled in the top right.
Also, in Display settings, switch off Proximity Wakeup, which activates on hand waves over the sensor for notification previews. Deactivating prevents constant sensor activity, preserving power.
Not every app has dark mode—like some readers or browsers with white backgrounds. Quick fix: Swipe down the notification shade and tap the Invert Colors quick tile.
This flips colors (black to white and vice versa), letting AMOLED efficiency shine. Toggle off when done.
