These answers explain how the phone’s battery, fingerprint sensor and expandable storage affect everyday use.
How long does the Lava O1 battery last, and how fast does it charge?
The 5,000 mAh battery is designed to support everyday activities such as calls, messaging, browsing and video playback. Actual battery life depends on screen brightness, mobile data use, signal strength and app activity. The phone supports 18 W wired charging through USB Type-C, but charging time varies with usage and conditions. If you spend long hours away from a power outlet, battery capacity is worth considering alongside charging speed.
Can I unlock Lava O1 using my fingerprint?
Yes. The phone has a side-mounted fingerprint sensor and supports face unlock, giving you two biometric options for accessing the device. The fingerprint sensor can be convenient when checking messages or opening apps frequently. It also includes proximity and ambient light sensors, which help manage screen behaviour during calls and adjust brightness to surrounding light.
Can I expand Lava O1 storage with a memory card?
Yes. The phone has 64GB of internal storage and supports a microSD card of up to 256GB. Extra storage can help you keep photos, videos, music and documents on the device. However, its hybrid SIM slot means you may need to choose between using a second SIM and a memory card, depending on the slot configuration. Check your storage needs and SIM requirements before buying.
