The Redmi 14C will experience lag for the following reasons:
1. When the battery level drops below 4%, the CPU frequency is reduced to conserve battery life, which will cause the device to lag. It is recommended to charge the phone to at least 5% before using it to avoid this issue;
2. The Redmi 14C will experience lag when the storage space is low. To avoid this issue, ensure that sufficient storage space is available: for a phone with 64GB of storage, it's recommended to have at least 8GB of free space. For 128GB and 256GB models, it's recommended to maintain at least 12GB of free space.
