Uh-oh! 3 days standby??? With or without 3G and WiFi?

My iPhone 5 will last right around 6 hours of usage, easily 24 plus on standby though. As long as you charge it at work or overnight or in the car you won’t ever have problems with it running out.

I’ve found access to the cellular network to be the biggest killer. Heavy access of the web with few bars drains the battery like nobody’s business. On the flip side, an iPhone on airplane mode lasts days and days.

I agree up to a point. My iPhone4 refused to forget a group of single pdfs. I had renamed them, so the iPhone4 showed two sets of pdfs, where one set would not play, but would not go away when I sync’d w my iMac in iTunes11.0.2. I had to wipe the iPhone4 COMPLETELY as a new iPhone4, to get the original group of pdf’s to go away.

But I always try to restore from backup first. It takes several hours to set up a new phone to the last state.

Calibrate the battery first, so that the usage stats are useful. The controller chip in lithium ion batteries is the source of the battery remaining charge in the display. So if that is not accurate then nothing is accurate. There are plenty of background reasons for less than optimal battery life:
• Display brightness – setting the brightness to above 50% has an impact on battery consumption.
• Bluetooth & WiFi – I know someone that goes to Disneyland & the battery is drained before the end of the day. If a headset is not going to be used or if WiFi is not accessible in that location, turning off those features will save power. Unless a park guide app is being used, then location services can also be turned off. Fewer pings & GPS access will conserve more battery

Cheers !

Restoring from a backup is a bad idea. You always want to set it up as a new iPhone because if the bad battery life is caused by software, it’s in your backup and will just come right back over when you restore.

This is really only meaningful data when your iPhone is just about dead.

My iPhone 5 gets about 5-6 hours of usage out of it and I have to charge it every night, but I use it often throughout the day. Sitting around on a weekend without usage I can let it rest and only charge it once between Saturday and Sunday though since there’s less usage.

Usage makes all the difference, including what apps you use, video, photos, etc. and MAPS is probably the biggest battery hog of them all, if you use turn-by-turn on a road trip you will drain an iPhone 5 down before you reach your destination past a few hundred miles.
