If you're doing mining, you will notice a decline in the performance of your mobile phone. I experienced that myself in my new phone back when I was active in mobile mining.
The battery is easily drained compared to when I have not yet installed it. There is research done on this already because it uses the cell's resources, so if you're going to mine using your cellphone, you should understand the consequences and disadvantages.
I advise that you use an old cell; the rewards may not be worth it if you're going to use a new one.
