Reading novels on the phone would not reduce the lifespan of the phone, but it might have some impact on the performance of the phone. When reading a novel, the phone needed to process a large amount of text messages, which would consume the phone's performance resources. If the phone's performance was insufficient, it might cause problems such as stuttering and flashbacks when reading novels, affecting the user experience. Using the phone to read novels for a long time might also affect the battery life of the phone. When reading a novel, the mobile phone needs to constantly receive and process information, which will consume the battery energy of the mobile phone. If the phone is used for too long, the battery energy consumption may cause the battery life of the phone to be shortened and need to be recharged in time. Therefore, when reading novels on the phone, one had to pay attention to the time and frequency of using the phone to avoid negative effects on the phone. If you want to increase the lifespan of your phone, you can try to reduce the time you use your phone or use a phone with a longer battery life to avoid frequent charging.
