Why does the iPhone take so long to start up after it dies?

Am I missing something?


When my iPhone dies completely, I plug it into my MacBook Pro and it takes a solid 7 or 8 minutes before the silver apple shows up and it turns on. Whenever I push the home button, the drained battery icon shows.


Is this normal? The same thing happens with my iPad, so I'm guessing it is...really *****.

iPhone 4S, iOS 5.0.1, White, 32GB

I fully understand what you are talking about, I get annoyed with this all the time. It's strange that when my Mac or Vape are completely flat I can plug it into the wall or a computer and it turns on straight away. If someone could explain the difference then I would greatly appreciate it.

I was told at the genius bar that it's a VERY good idea to run your battery all the way down as often as you can. If you don't do this you shorten the life of your battery.


Say you charge it at 3% most of the time, eventually that 3% becomes your new zero....so then when you charge at 3% all the time again, THAT 3% (which is not about 6%) is the new zero and so on.


I try to let mine die as often as I can and have great luck with battery life.


You all are so harsh on the guy.......I hate how long it takes to get enough juice to turn back on. Especially when life gets busy and you simply forget it's so low.

Apple has designed the charging system to handle many different battery usage events. Deep-cycles as Cheryl has described is not advised for a long-term usage plan.


Some recommendations from advisors in battery tech:

"Fully drain charge, then drain again and charge. Apple recommends this once a month for the health of the battery."


"Memory issues" are not valid where Li-ion batteries are concerned and in general is a bad practice."


Me personally, it all depends on if I am staying in the city or not... otherwise I turn off 3G and wait until I arrive in the next town.

Nonsense. Lithium ion batteries do NOT have a memory effect. The only reason to run the battery down unil the phone shuts off and then fully recharge it is to calibrate the battery sensor. Either you misunderstood the Genius in question, or he is confused. Read Apple's official advice:

I agree with Peter. I have an iPhone 5 and a few other apple products, and it takes a very long time, even longer than my macbook to power up from a depleted battery. My friend has a Samsung Galaxy S3 and it powers up the instant she plugs it into a wall from a dead battery.


Very inconvenient.


Still love apple though...... 😊
