iOS 8 GM battery life

bahndoos said:
I am not confident about this anymore actually - my 5s has been behaving veeeeeeery strangely on GM. This is what has started to happen:

After a full charge, I can leave the phone unused for 5-6 hrs and I will see maybe a 2 or 3% drop in charge. The minute I start using the phone for basic stuff such as browsing, whatsapp, non-intensive games like wordbase and letterpress etc., i will see the battery start to drop almost 1% every few minutes, sometimes it will drop 2% at a time. If I stop using the phone, it will go back to near-zero drop in battery, for hours in standby.

Too rapid a drop in battery with light use, and virtually no drop in standby.

I am absolutely flabbergasted.:confused:

Anyone see this happen? Any ideas whats going on?

This is exactly what's happening to me. I've been on 50 for such a long time and jumps down to 31 (on iPod)

On iPhone it's less profound as it drops about 5-10% at a time and stabilizes a bit before doing it again

Does your phone heat up while charging as well?

This is precisely what's happening to my iPhone 4S. I've made seperate thread about it, thinking that it was music app.

Listening to music on my earphones with disabled display drains about 1% battery each 2 minutes. In contrast - on iOS 7.1.2 it ate about 1% for 20 minutes of music.

It is warm but nothing out of the ordinary. I only have 25 apps or so on the phone as well. The battery usage thing keeps reporting "home lock screen" as the biggest culprit.

In general I thought that the overall power usage on iOS 7 was a little higher then iOS 6, I turned off the fancy animations (I think the Parallax effect wastes CPU cycles), turned off a lot of the location services and set my email to fetch: with all those changes I can listen to music all day and get home with at least 40% left. Make sure Background app update is also off, facebook is the real hog though it seems to always trying to pull data.

Yes, the lock screen is always on the top 3 greatest usage apps for me. Also, my usage and standby stats keep blanking out, I.e. Appear as ' - ' instead of an hours and mins count.

I've disabled WiFi, data transfer, Bluetooth. I've killed all other apps. It was just Music.

Fun fact - battery meter in settings claims music took only 15% of energy, lock screen had 30%. Heh, I've not even unlocked my phone once during that time.

Edit: I think it's also worth to notice that my 4S was getting warm playing music on iOS 8 GM in contrary t iOS 7 on which it ran cold. It is not hot but you can definately feel the warmth.

I had to go back to iOS 7 and when I did the battery issue persisted so I had to set up the device like new and download my contacts and photos and stuff manually. This issue has came back and it's giving me stress!

And did you go to Apple and have them test the battery. Why stress out when you could do that and have an answer. Heck even if there isn't an apple store you could call phone support and they can run a remote read for you.

Interesting, because for me wifi seems to be out of whack, creating more heat and battery drain compared to 3G. I am also in an area of spotty 3G only, no LTE. Just wondering if the 5s may be having a tough time handling 3G, because usually in the US, LTE is great but if the signal goes to down to even 4G, excessive battery drain immediately begins...
 
Interesting, turned on the flashlight for no longer than 10 seconds at most and it already shows up as being responsible for 10% of battery usage in the usage section.

I had the same thing today. Turned it on this morning for less than a minute and saw it comprised 37% of my battery usage when I got to work, followed by lock and home screen at 22%.

Update: just checked again after posting this message and flashlight is now at 49%. Think I may be going back to 7 tonight. Note that I haven't touched my flashlight since early this morning.

Could be that the calculations for that section are just weird in some way and that's where a potential bug might be, and not with the actual battery usage or anything like that--of course that's assuming you aren't seeing battery weirdness yourself, not counting what that section mentions.

I wouldn't say weird. I've kind of gotten used to excessive drain on early versions of major releases. There's really not a whole lot I'll miss from 8 anyway. NBD.
 
I just went back to 7. hacked around with the sms.db file (changing the version number from 8008 to 7006 via sql) and voila! my iOS8 stuff imported perfectly into is. Didn't lose anything in the week i was on 8
 
It's the weather widget in Notification Center. Disabling the location service on that greatly improves the battery and heat issues. Gotta be a glitch in it.

Weather widget on theock screen?
 
I have *hundreds* of entries for "stack+backboardd" process errors in my diagnostics log. Anyone know what this is specifically? Google tells me it's a companion process for springboard, but not much more.
 
Resetting "network settings" fixed my battery issues. If you also have battery issues, please try it.

iOS 8 is awesome now. :p

EDIT: This is how it looks like now:

Mind explaining this? I changed the version to 7.1.2 via .plst editor and that didn't work.
 
iOS 8 GM battery life

The first day I installed GM, battery life was horrible. I noticed my location services were constantly running too. Since then, my battery life has been much better and location services backed off a lot. I reset all settings and network settings. So maybe that had something to do with it.

Use a program like iBackupBot to extract the sms.db file from ios8. Open it up using a SQLite browser and change the client version to 7006. Then re-import the sms.db file into your ios7 backup (or newly created empty iOS7 backup if you don't already have one) Finally, use iTunes to restore the patched backup
