Re: why does my lumia 930 battery drain fast
10 days from a single charge? I'm guessing you've turned a lot of features off, and even set the screen to the dimmest possible setting, to reach that. That beats the longest-lasting smart phone in terms of battery life by more than a factor of 10 if you were using your L930 under normal use.
Here's something you can try: Activate Battery Saver (always on, which the phone will say is not recommended), keep your screen at the lowest brightness setting, prevent mobile data, do not connect to Wi-Fi and prevent all apps from running in the background (also from Battery Saver). Avoid playing games, opening apps and taking photos. Limit calls to just a few seconds per day and SMS to around 2 per day. Then, let us know how long your phone lasts.
Your battery life may last long under those conditions, but your "smart" phone won't be functioning at its full potential.
