I backup to iTunes before every iOS update. I haven't had issues on my phone, but when I upgraded my wife's 4 ti iOS 7.whatever, the update failed. I had to restore the phone, apply the update and then restore from the backup to get it back up and running.I always let iTunes do the heavy lifting rather than the phone. As for routine backups, my phone automatically backs up to iCloud when it feels like it, and I try to do a manual backup to iTunes on a monthly basis when I let the phone's battery drain.

I didn't think I was crazy. Finally somebody else with some sense. grin

As you see it helped you back out of a bad upgrade. It is a much quicker restore doing it from iTunes as opposed to iCloud. Especially if you make sure you let it copy all apps from the phone during the backup, otherwise it has to download all of them again.

You shouldn't let the battery drain... not good for LiPo batteries.

Also.. iOS 9 has a new feature.
Low Power Mode

Yes, I'm aware of the low power mode. Battery usage has never been an issue for me. As for drianing the battery from time to time, I've heard several arguments, pro and con, on whether it keeps the battery in prime condition.

Not true. It helps to calibrate the computer/sensor in the battery so it knows how much of a charge it has. Same for laptop batteries.

What is bad is to let one drain all the way and sit that way for weeks or months. That will kill the battery since it will slowly discharge below the cutoff rate that the hardware shuts off at. When it gets below a certain charge level it can't be recharged.

And since no one here ever believes me; cry

Li-ion should not be discharged below the manufacturer specified level and there are several safeguards to prevent this from happening. The equipment cuts off when the battery discharges to about 3.0V/cell, stopping the current flow. If the discharge continues to about 2.70V/cell and lower, the battery’s protection circuit may put the battery into a sleep mode. This renders the pack unserviceable and a recharge with many chargers is not possible. To prevent a battery from falling asleep, apply a partial charge before storage.

Hmmm. ok. I had read up on LiPo batteries recently and read that you can make them last longer by not fully charging or discharging them, keeping them between 20 and 80%. Hence the first warning you get at 20%.

The reason to discharge is to calibrate the battery sensor, not the battery... which is reflected in your little green power bar. These batteries last for years and have no memory... and I don't think a batteries effectiveness will change much at all in only a month. The only benefit to discharging them is so the green bar is more accurate.

Also.. Apple says nothing about draining your battery to extend life... in an article about maximizing performance.

If one wants to extend battery life they would be wise to find out what needless things are sucking up the juice.

omg, I am here for a Mac related question. How is everyone?


Anyway, the word fubar gives me pause. Unless it means Fantastic Unequivocally Beyond All Reason. My son and I are two of the 48 percent who haven't taken the plunge yet. Should we dive in? My son had a bad experience with the last first digit upgrade and is wary and I am always wary. Anybody who would take it back now if they could've waited?

Just make sure you turn off Find my iPhone and back it up to iTunes first in case the bug bites you.

Personally I'm waiting till the bug fix till I upgrade. I hate fixing my own stuff. I'm not getting paid for it! laugh

On the OS I'll jump into beta/new versions, but on a different drive from my production drive. On the phone there's no different drive option so I don't do first versions.
