rhis is so simple put the case on and forget about it u too you are running out of battery, you don’t need to remember to charge the case making it the ideal case for me as I would forget. I spend much less time with my phone plugged in and I’ve not had my phone die once since I purchased this case. It’s not too bulky and even after a few accidental drops it works fine and has protected my phone. This is a must for all iPhone users
