The choice of battery capacity will depend on how you use it. The more you use it, the more battery it consumes, and in that case, it is better to consider a long battery life. If you also need to travel outdoors or want to go on a trip, you will not have immediate access to a power outlet to charge your phone. In this case, choose smartphones that have an ultra-optimized battery, meaning with long battery life during calls, with the screen on and in standby, and with the screen off. In our X-LAB, the R&D laboratory, we develop high-performance batteries thanks to a large capacity, measured in mAh, and low-energy components, such as the processor. Thus, we offer models with a lifespan of 800 charge cycles.
