The Casio smart phones have not been highly rated. I tried using a coworkers once. No fun. Is it too late to return it? To retain the utility recommend a Samsung Galaxy S3 or S4. Then go with the Lifeproof Nuud case. Either of those phones will be light years ahead of the Casio. Battery life is very subjective. If the phone is constantly roaming the battery will be short lived in any phone. I converted our phones to QI wireless charging. I no longer plug in the phone. I have what I call a first generation QI car charger in my work vehicle. It works ok. Depending on the carrier, some phones allow turning off the 4G. This should significantly increase battery life. Especially if the 4G coverage is spotty.
