Samsung Galaxy M40 battery capacity

The phone's battery is a non-removable 3,500 mAh Li-Po battery. The battery can last a full day, with 5 hours screen-on-time. The Snapdragon chipset improves battery life to give optimal performance. Even though the battery capacity is not the best, the 15W fast charging ensures that you have a full charge within a short time.

The phone warms up during extended gaming sessions and when charging, but that should not be a point of concern.

Speaker and call quality

The device comes with an on-screen earpiece that is lacking in most phones. The earpiece is spread out through the whole screen that makes it vibrate during a call. Screen-on-sound technology improves call quality and audibility. It might take a while before you adjust to the vibrating, but once you do, it will not be problematic.
