I'm holding off for a couple of days until I hear some feedback on 8.2 and so far it seems to be good/no worse but how about battery life? I'm still on 8.1.2 because my battery life took a hit on 8.1.3

It has been 1 day since release, come on with these battery threads. Battery problems are not always update specific and could be a variety of things. iOS also apparently indexes after updates so it takes a while to settle.
8.1.2 actually sucked for me since it killed 1-2 hours of usage on my devices whereas 8.1.3 was much better. There is no science to it but apparently every update causes problems to different people, this goes back all the way to the early days of iOS. These threads need to stop, especially 1 day after release.

So on the one hand you're saying these threads should stop, but on the other that 8.1.2 gave your device terrible battery life?
I would say that this information is pertinent to some people.
Battery life is the one good thing about my 6+ and I don't want to install an update that robs me of some usage time.
 
I agree with Crashoverride77, in his point about pretty much any update can give those installing possible problems. One issue I had with 8.1.2 was more battery drain on my iPad4. Once 8.1.3 came along my battery went back to normal or maybe even better.
I have been wondering now for some time if some of the problems we see with each new update has anything to do with each device. Meaning this... Each device sold I'm sure meets Apple spec, but as with any manufacture each component has its own tolerance. Let's say if one person's device just meets spec, yet someone else has a device that meets spec on the top end. Is it not possible when each is loading with an update or a new app it could produce slightly different results? I know for fact this is possible with engines and reliability.
Anyone have thoughts to this?

I think part of it is that it can't really be gaged over a single or even a couple of days. Generally at least a few days if not a week or more would be needed to get more realistic and useful information, and even then only if more than just a few people provide it (since just a few separate anegdotal experiences don't really paint a good enough picture of what it can be like for most).
 
Some updates do tend to cause more battery complaints than others though. There is always the particular user's configuration/bad install angle but sometimes a clean install and then everything back exactly as before will still give worse battery life for some people than the previous version of iOS. They them revert to the previous version before Apple stop signing it and all becomes well again. There is no explanation for that is there. It can be put down to the update, but then some people say that their device has no issues with it...
 
I've done extensive testing of iOS 8.2 on my iPhone 6 Plus.

Having had it installed for a full 2.895 minutes, my projections indicate battery life is increased a very significant 1.002%

That's an amazing accomplishment on Apple's part!

WoooHooo :)
 
I have not updated my Plus yet but if battery life is even better than what I have experienced then I will be even more of a happy camper.

Despite all of this talk about 'indexing', and iOS needing a week to 'settle', it's funny how my 6+ on 8.1 was fantastic straight from the box and continued to be so until 8.1.2
From the very first charge to the 10th, I had over 11 hours of usage. If you don't have a repetitive usage pattern or you're unaware of previous battery usage results then I can see how the OP's post (mine) would be difficult for you...
8.2 has been out 24 hours and some people will be able to tell how their battery life is compared to 8.1.3 or 8.1.2
 
I've only had it installed for 24 hours, so take this for what it's worth (which is not very much), but so far battery life appears to be consistent with what I had experienced under 8.1.2 with my 6 Plus.

I haven't started downloading and playing with the watch app or the new health apps, so keep in mind that the battery will obviously die faster if you increase your usage to try the new additions.

And, FWIW, I haven't noticed any major changes in battery life from when I got the phone with 8.0.1 across any of the updates, after accounting for minor anomalies that are likely explained by unusual usage patterns (ie using an app like facebook that is particularly power hungry for what it does) or weak signal.
 
All seems fine on iP6. Installed as soon as it dropped so about 24hrs now. Maybe even a little better as sitting on 98% with 1 hr use and 7 hr stdby.
 
Seems a little better for me than 8.1.3 and been running it for just about 24 hours and haven't had one jetsam event yet *knocks on wood*

My joking post aside...

I find that it takes me two weeks of daily usage to judge battery life as fairly as possible. My usage is far greater than most since I'm often traveling all over the USA, Italy, France, Germany and Spain. Therefore a smartphone is absolutely essential for me.

It's been a full day now since I installed 8.2. That represents 11 hours of active usage. I'm extremely pleased that the frequent hourly crashes are gone. That's a very significant improvement.
 
I used it heavy today and don't see it as any worse. I did install the new Google Calendar, so things may be skewed a little.

But, how it performs for some may be different for others. Always been that way always will--you just gotta try it--;)

Oh my gosh are you serious? I'm sick of seeing so many jetsam events, I easily get at the very least anywhere from 5-10 a day. On top of that, generally bad battery life and a bit of warmth from lighter-moderate usage at 20% brightness.
 
I had a fantastic battery life on my iPhone 6 Plus till now.

But 8.2 has reduced the battery life significantly.

Prior to it with moderately heavy use, I used to have about 40% battery when I reached home at night.

With 8.2 its now about 20% when I get home.

So its bugging me right now....but I will wait for it to settle down. I'm sure it will
 
My battery life is unchanged so far. I do have a question, what is a "jetsam" event? Sounds nautical to me.:confused:

It's a nautical low memory event, the maritime equivalent of having no wind in your sails.☺️

Interestingly enough I had those for almost a month in December and then suddenly it stopped. Then just as suddenly started daily once again last weekend (so I can't even connect it to 8.2 since it started right before it). Go figure.
 
So far I've noticed improved battery life on my 6+ compared to 8.1.3; getting about 12+ hours of usage on a full charge compared to 10 before the update
