Maybe this will help fix the battery issues. My iphone 5 battery life is horrid, even with LTE disabled and all mail data being set to fetch instead of pull. Is there some known issue about this? I can't be the only one.

I'm having a similar problem - but only when LTE is enabled... and I have spotty LTE coverage. When I'm in "the city" - LTE coverage is great and I get amazing battery life. As soon as my phone starts switching between 4G and LTE... my battery drains super-fast.

  Your issue is a known issue with LTE. In spotty areas the phone keeps switching from LTE to 4G, and then when in 4G searches for LTE. The searching process, which requires powering separate radios for each protocol, is expensive power-wise. If you keep bouncing in and out of LTE this is bound to happen.

    Is there any long-term fix for this? Or do I just have to wait for improved LTE coverage (or keep LTE turned off in those areas)?

      It doesn't seem like a software issue to me, so I'd guess no fix will come aside from LTE coverage improving in your area. It's just the cold hard facts of where the state of cellular radio technology is today. It's pretty amazing as is that the iPhone 5 can be so much thinner, lighter, support a larger hi-res screen, be twice as fast, and support LTE. The spotty LTE issue is just one of those compromises that I don't think much can be done about.

My iphone 5 has actually been impressive in terms of battery, lasting several days at a time. Where are you physically located? I wonder if bad coverage could be affecting your experience.

Expected behavior with the iPhone 5: ~10-15% better battery life. You've ruled-out the known spotty LTE switching/searching issue, I'd perform these additional experiments: 1) Disable iCloud sync entirely for a day. In iOS5 there used to be a bunch of battery life problems caused by devices getting caught in an endless loop of pointless background syncing. Maybe you're still hitting something like that. 2) Turn of location services for a day. Maybe you've got something like Find My Friends taking up too much juice? 3) Turn of email "push" for a day. Maybe you've got too many email accounts? Failing that, maybe you've got a dud? Take it to the Apple store and they can look at your device energy usage logs. They'll most likely tell you to do a fresh iOS install suspecting a software issue.. but in the end they might just switch you to a new device.

Backup, restore, restore phone from backup. I had the same issue. My phone was also noticeably warmer. It was doing something. Now everything works great. Battery life even with LTE is quite good.
