OK I hate to be the first to introduce this topic in ios8. But is it just me or is battery better? So far I'm on 82% and 1.27 hours. Best I've ever had and I'm using it lots today testing the news ios. Usually I'm down to % in high 60's or low 70's by now. Any other thoughts?

Downloaded and installed iOS8 yesterday around lunchtime, so far so good. Battery life hasn't taken a nosedive compared to before but I will know more by this evening after a full day's use.


If it ain't broke, don't fix it!

After using iOS 8 on my iPhone 5 for a few days I find that the battery life is slightly better in spite of having to tether my phone with my PC for a day because my ISP was down for that day. The first day was spent "Playing" with the new OS so I expected it when I had to put the phone on charge a couple hours earlier than usual. All in all, the battery life somewhat better but not by any huge amount.

Battery life has suffered on iOS 8 it seems. But I think the culprits are 1. location based alerts in system services. It keeps geofencing on non stop. I couldn't figure out why the icon was on my status bar. I finally found it in system services and toggled it off. 2. All those cool widgets. They love battery juice. SportsCenter is a hog. Some of those weather widgets are eaters too. It's all a bit rough on a 13 month old iP 5. But I'm too old to worry about those things. I'll enjoy my iPhone. I do find ways to conserve. Toggling off location based alerts was one of them.

Apart from location services, disabling background app refresh will not eat your battery. I have tried it on ip5.

I have an iPhone 5 with iOS 8. My battery drains so fast. Example, I have 32% battery left and my phone dies. I plug it in and it reads 75% battery. I don't understand why it does this, or it says 25% battery, I do a hard boot and now it says 75% battery. Any ideas or suggestions why?
Thank you

Fast forward to iOS 8.1. My battery is draining at an alarming rate. I've checked everything in settings and have done all the battery saving sets and what not. Month ago, starting at 100% at bedtime, by morning it would be at about 97%. After updating to iOS 8, it was at 94% in the morning. Now, after updating to iOS 8.1, it's at 84% in the morning. Yesterday it drained really fast. This is on an iPhone 5. Is anyone else experiencing this? I'm not sure what to do!

How is your network signal? Reset your network settings and do a hard reset and test it tonight. Post your results.

I had already Reset Network Settings and a hard reset. I ran it down to below 1% then charged up to 100%+. My wifi signal is good. Verizon goes back and forth between 3 and 4 dots. I found some new apps with background app refresh on. I suppose this is about as good as it gets for a 14 month old iP 5 that's been used a lot.

Your battery usage looks perfectly normal. You aren't going to get better than that with your type of usage.

Yeah, it went down fast after 8.1. But part may have been several new widget apps that were using background app refresh. It's not draining as fast now.

Something else that a lot of people don't think about is when you are using wifi at home, it's not using any data. If you leave your house and forget to turn off wifi all day, your battery is going to take a hit. I often leave my wifi on and notice the battery draining at a rapid speed. Just a thought.

I don't notice any hit with wifi still on but no wifi nearby. Maybe because I have cellular data off? Who knows.
