sorry in advance if this has been asked before. so i am having battery drain issues on my jailbroken iphone 4s. i am planning to jaibreak again to see if i can fix the issue. here is my question: if i restore from a back up after the jailbreak did i defeat the purpose? would whatever is draining my battery just be back on my phone? i have a backup saved to my computer. i am assuming my issue is most likely related to a cydia tweak so if i only restore everything that is not cydia related should i be fine? after the restore i plan to add cydia stuff one by one and test to see what could be causing the drain. is this the right process?
