I have the Sony xperia z3 compact. When the phone is idle and screen off I have no battery problems.

But for example if I'm on a train journey using 4g for social media and some web browsing the battery just gets battered! It can lose like 10-15% an hour!

Is that normal?

Thanks for any advice.

Also just to add, the phone gets really hot when using 4g.

Hi @Jimardee, I'm so sorry to hear that.

Does it occur strictly while traveling, or if you're stationary too? If you're going by train, do you experience that the network coverage gets poor and that your device changes networks from 4G, to 3G and then back or something similar? What I'm thinking is that the device may get poor reception and move in and out of network coverage and therefore the device has to keep up and search for networks frequently which may affect the battery life.

Does the same occur if you set the network mode to 3G and leave it at that? To try that, go to Settings > More > Mobile networks > Preferred network type > 3G only. Does that help?

After experiencing a battery drop over an extended period of time, could you go to Settings > Battery usage and see which apps are on top of this list? Feel free to PM me a screenshot of the graph and app list here and I'll look in to it for you.

Let me know some more details regarding this and I'll do my best to assist you!
