I've recently bought an iPhone 5 (locked, unlocked with a goguo gevey) and I must agree that iPhone is one of the best devices ive ever had lol. Every night my phone loses about 30% charging overnight and i've gotten sick about it, every night I charge and sleep and in the morning I find 30% drained without calls and merely a sms? I always believed I had some jailbreaked tweaks that might be responsible for this but last night I put my iPhone on airplane mode and slept and in the morning I was amazed to observe the battery drained was a mere 3%? Im positive for sure that network is draining my battery but why? The network signals are amazing here and ive never faced such problems with other phone?
