Learn how to extend your battery's performance.
Applicable for all realme smartphones.


Battery safety

Smartphones use Lithium-ion battery. Lithium-ion battery provides lightweight, high energy density power sources for devices. It also has good plasticity and it is the safest one. We use Lithium-ion battery to ensure the good performance of Realme smartphone.

Use Realme original accessories.

Lithium-ion battery is a smart battery which might not be fully charged or its maximum lifespan cannot be reached with an unoriginal charger. (Including Power adapter and USB Cable).


Use at a suitable temperature.

Smartphone battery is designed to have a good performance in a wide range of ambient temperatures, with 16° C to 25° C (61° F to 77° F) as the ideal comfort zone. High temperatures during charging may lead to battery degradation and charging at temperatures above 40 °C will degrade battery performance, whereas at lower temperatures the internal resistance of the battery may increase, resulting in slower charging and thus longer charging times. When using your device in a very cold environment, you may notice a decrease in battery life, but this condition is temporary. Once the battery's temperature returns to its normal operating range, its performance will return to normal as well.

*To avoid battery damage, realme smartphone will automatically stop charging or using at extreme ambient temperatures, and alerts you "Temperature is too low/high, the battery cannot be charged", "Temperature is too low/high, the battery cannot be fully charged".


Do not use when charging.

1. Your phone might quickly get warm or even cause damage if you operate a lot during charging. Charge the battery whenever you want. It is not suggested to let it discharge 100% before recharging.
2. Do not fully discharge your phone's battery.
3. Charge your phone when your battery level goes down to 10%. If phone's battery is fully discharged, the battery could fall into a deep discharge state, which will cause it to be slightly damaged.


Store the phone long term.

If you plan to store the phone for a long time, charge it to 60% or above every month.


External environment.

Avoid to expose your phone battery to high or low temperature, humid environment or sun exposure.


Charger Usage Notes:

1.Only use the charger specified by realme.
2.Charging voltage should be consistent with that specified on the charger. Using mismatched voltage might cause leakage, fire and damages.
3.Do not use a power socket that is incompatible with the charger. Make sure the charger is plugged in firmly to avoid any fire hazard.
4.Do not charge your phone with a partially damaged charger, for that could result in electric shock, fire or other damages.
5.Do not charge your phone near washbasins or other water containers, or in wet locations such as bathrooms. Take care not to spill any food or liquid on your phone or charger. Do not touch chargers, cables or power socket with wet hands. In case the charger gets wet, unplug all cables, allow it to dry thoroughly before charging again.
6.Do not disassemble or modify the charger or cables yourself.
7.Do not place heavy objects on the charger, for that might cause electric shock and fire.
8.Before cleaning the charger, unplug all cables (hold and pull the plug instead of pulling the cable, otherwise the cable will be ripped off).
9.Do not charge your phone when there is lightning or thunderstorm. Do not make phone calls while charging.
10.Avoid exposing your charger to following conditions, such as direct sunlight, temperatures lower than 5° C or higher than 40° C, damp and dusty places or that with excessive vibrations (might cause breakdowns), places near electrical appliances such as TV and radio sets (might cause interference to images and sound).

* Pictures, settings and paths might differ from your phone, but that do not affect the description in this article.
