    I upgraded to 8.1.3 ios and my battery life of my iPhone 5s is about 3.5 hours of usage!

    One of the issues is that my cellular signal is weak where I live and so the phone switches between no service and connection. Could that be the main problem?

    Any tips to improve the battery life on an iPhone 5s and 8.1.3? Thanks

    Your phone constantly monitors it's connection to the network. When it detects a less than optimum connection, it increases it's transmitted power in an attempt to improve the connection. In marginal signal conditions, your phones transmitter is using a lot of power.

    Go to Settings > General > Usage > Battery Usage

    What is the top application/process using battery? That will help us narrow down what is going on.

    Also, do you have LTE available where you live? If not, turn LTE off. If there is no LTE service it is wasting even more battery trying to find it.
