Is it okay to let the battery completely die on a jailbroken device or power the phone off completely without causing any damage? I am on a 4s IOS 5 device jailbroken with absinthe. Due to the short battery life that I am receiving I am afraid one day I will be out and about and my battery will completely die. I am not always around an outlet or USB port to charge my phone and I am not interested in battery case packs. It would help if I was able to turn the phone completely off around without having to re-jailbreak and start "over".
