iOS 9 Beta battery life

Now I changed to "2g" to see what happens, and no "battery saving moded" enabled. I think it definitely have to do with the mobile data modes.. and something happening when enabled.. and maybe 3G/4G..

My Phone is connected to Wifi and mobile data is set to 2G. This is not really better in this case. Now the battery is by 72%.

Well, enabling mobile data and 2G and the battery starts to drain again.. I can clearly see a difference here now..

Try disabling mobile data completely and see if there's a difference for you too.

Well.. I now have the phone with with Autolock disabled so the display is on the whole time and Mobile data completely disabled and there's no drain on the battery. It runs well and it doesn't get got at all.. So yeah.. on at lest my phone it's definitely mobile data that is the issue behind the battery drain, wonder what it does differently to running on Wi-Fi, haven't even enabled battery saving mode either and still no drain 🙂

So all I have to do now is use my 4G mobile router instead and connect my iPhone to it when on the train to work 😝 And the battery will probably last all day without any issues.. 🙂

I've found that turning off everything in search in the settings area seems to help tremendously. I haven't had a chance to narrow down exactly which toggle is responsible for the drain, but I'm actually able to charge my device from a USB port now.

I am checking it out, have enabled 4G and will go through them one by one, start with disabling all and enable the Siri stuff. Might be something in there that uses the mobile data and somehow bugs out totally.. But I'll know soon enough 🙂 Thanks for the tip.

Hi.

I have the same issue 😟.

Paper app was consuming resources backgound, slightly better performance.

You check applications are running in background and location.

Good luck!

Mine is worse. I lost 35% in 2 hours 55 minutes. I tried to create a ticket but I couldnt get battery logs to add.

Exactly. Not all of us can fully test our apps while plugged into the wall.

I too have been experiencing the same very fast battery drain that you are all talking about. I have an iPhone 6 16GB. I just recently re-install iOS 9 right over my previous iOS 9. Since doing this my battery life experience has greatly improved. I can't exactly say that things are back to normal but very much better than before I re-updated. I did try re-installing iOS 8.3, restoring from backup and then upgrading to iOS 9. 1st and 2nd time same results, battery life out of control. Now that I just updated right on top of iOS 9 and things have greatly improved. If things change I will re-post. Good Luck!!!

Reposting this with more info:

When the beta came out yesterday, I did an upgrade and not a restore. Today I litterally watched the battery percentage drop 1 percent every two minutes while I only had the home screen active (background apps disabled, location services disabled, etc). I kept checking the Settings -> Battery page and it show "Home Screen" at 15% of the usage, which was completely wrong.

Today I did a complete restore and now things are better. The Settings -> Battery screen not only showed Photo App as the top user (I have over 8 gigs of phots and videos), but it also showed it as "Background Activity". I didn't see that before I did the complete restore. Now, Mail, Messages and Calendar also show that. I'm sure the battery will still drain faster than with a production version, but at least it seems like the reporting is working correctly and it allowed me to understand what was sucking the life out of my battery.

---------------------------------------------------------

As an update, I have an iPhone 6 64GB model on which I did the complete restore/iCloud restore. Currently,

• All Background Refresh is turned off
• All mail is set for Fetch
• All location services besides the Find My Phone are truned off
• Bluetooth is turned off
• I have spent 8 minutes on a phone call.

I think there are two things going on. The first is that the Battery statistics are not reporting correclty unless a complete reinstall is done. The second is that the WiFi is using a lot of battery life. I'll keep a running list as to what I'm doing to try and extend the battery lifeLog:

I then restored my iPhone 6 only. No restore, no location services, no email etc.

• 2:57 - 62% - Clean install of iOS 9 Beta 1
• 3:57 - 59% - Phone is lying face down. 190k of celular data. No applications reporting battery usage.
• 4:47 - 54% - Phone is lying face down. - 8% drain in almost 2 hours with nothing but the absolute basics.

So, it does indeed appear that there is a battery usage issue within the system itself. It seems any applicaiton on it will just exacerbate it.

I've noticed shocking heat whilst downloading apps - never done this before. Does literally feel like the phone is ready to go on fire!

What exactly do you mean with updated on top of iOS 9? Are you talking about installing the same Beta over an existing Beta?

Thanks for clarifying 😉.

Yes, that is exactly what I did.
