iOS 9 Beta battery life

Same thing for me:

I'm down to 59% after what iOS defines as:

Standby: 2:41

Usage: 1:56

However, I'm not near the 2 hours of real usage, that the phone claims... So something is chewing up battery at a rapid pace.

According to the stats, Home & Lockscreen is responsible for 30% of this.

I did a real Restore and whiped the phone before restoring the backup, so Iäm not sure taht will help you a whole lot!

/J

Same here. Usage all came from Home and Lock screen for me. Have disabled the new Notification Centre widget for battery life in case that's the cause. Will need to keep an eye it to try and figure out what the culprit is.

Yeah same problem here.... down to 52% battery in less than 2 hours... 😢 Plus my favourite game doesn't even work... lol

Not what i expected from the first beta..... i know it is normal as it is not a finished product... but claim like.. we got an extra hour and then i am down to 80 % in 2 hours and it is getting worse...... it is not a good sign.

All in all considering there isn't much new i expected this first beta to be more "stable" as in battery life..

Hoping for a quick fix or it is down to iOS 8 very soon.

You know it's a beta 1, right?

Also, after installing a new OS there's a high probability that the system is doing a lot on things behind the scenes, just because you didnt use it for two hours does not mean the phone wasnt busy.

Perhaps try it out for longer than a day and see how it goes. Personally, I have no expecation of battery life for easlky beta's. iOS9 may be designed for longer battery life, but the first beta release of it probably isnt.

"You know it's a beta 1, right?"

What part of "i know it is normal as it is not a finished product" made you think i don't know it is a beta / unifinished product?

Are you trying to raise your post count??

Back on topic, i have been using this beta since it came out, and after a full night of "doing a lot on things behind the scenes" i am sure today my phone is doing NOTHING! also because the battery readings ,as most noticed, shows that the most usage comes from lock and home screen.

Edit:

Also the phone seems to run a little hotter than normal, i guess it might be one of the reason / cause for the battery drain.

This is Beta 1. It will improve in future builds, so try not to worry so much right now.

It happens with Every Beta.

This is probably due to extra performance and usage data collected by apple. Its nothing really to worry about as its necessery metrics to better the platform. no Personal Data is ever collected by apple.

I also have same issue. Went down 14% just from looking in settings and wtaching a 3:42 music video in Music app. Also went down 1% in 1.5 mins just by being on home screen.

Considering it is my only device, I can't say i am forced to use iOS 9...but since it is good to test with the latest version, so i am here to report my finding..

Historically iOS betas alwasy had poor battery life but never had anything like getting 20% left half day ....wich is surprising considering it is an update tailored at improving battery life...

Will i survive? YES Do I understand it is beta? YES ....will it improve? YES an I worried? NO.... but I have to say i am not happy.. now i have to traverl with my battery pack always behind...::(

As a complete guess, it might be indexing things for the new Search/Siri functionality and therefore chewing through the battery.

Same issue here. From what I can tell and using Instruments to look at suspicious activities, the app Mail is eating a lot of the cpu. Turning push off and even activating Low power mode does not change anything

Interesting is;

I only have reduced battery life on my iphone 6. On my iPad Air 2 bettery life is not that bad. I think it's reduced too but not that dramatically.

The mail configuration etc is the same on both devices!

Same here, down to 30% in a couple of hours. Battery usage says 96% Home- and Lockscreen. 😟

Let's see if this gets better the next days. Otherwise I'll try to get back to iOS 8.

Yes, same here. Battery drains while the phone isn't being used. It's been horrible so far.

Glad I'm not the only one experiencing it. I'm definitely gonna restore this is pretty bad

Everyone knows Mat is correct. This happens every single year, and people still mindlessly update their only device and complain despite "knowing it's only beta 1." Metrics are being gathered, Siri is probably indexing, and likely little to no effort has gone into optimization of code or battery life.

Complaining here because you "needed to say something" isn't really helpful to anyone, so don't get all offended when you receive responses reminding you that there should be no expectation at all regarding performance or battery life in the early betas. Battery life usually starts improving after beta 2 or 3.

I hope that some of this may be due to indexing and that it improves for you soon, but you may want to reset your expectations if it doesnt.

I really don't understand people complaining about battery life. I think it's all the peeps who just want to have ios9 and are not bothered about developing, This is always the case with betas. In all fairness the beta is to be installed on a test phone which will be at your computer while your testing apps so what's the problem.

I'm loosing 2% per minute. iPhone 6

Every ios early beta since the beginning of time has done this. There is diagnostic data to be collected, things have not been optimized, etc.

You may learn eventually then to only put betas on development devices. Sorry but you knew it going into it.

I am seeing significant issues with battery life, but I guess it is BETA, so I am going to just have to live with that and hope it will improve. All we can do is be good testers and download our battery logs and send them to Apple for looking at.

Glad to see it's happening to everyone, else there'd be something to worry about 🙂

Personally, my test device is currently at 13% at 5pm, usually it'd be around 60% so the power usage sure is off, but the point is that it does not matter. As has already been said, there's likely no power conservation going on right now, and I'd expect low level logging is active.

Leave the device plugged in all day (like I will be tomorrow!!)

As for "development device only" I fully agree, yet I happily install on my primary iPhone6 because that is my dev device. If it breaks or goes on fire, I have a perfectly good iphone 5S that I can live with. Hard to get to grips with an OS and do testing if you dont actually use the phone! So yeah, installing on primaries is fine in my opinion; but only if you dont really care about things like data loss and power loss !

I don't see people complaining here....rather discussing about battery life...

You might have an app that needs indoor testing.... not everyone does 😉

I understand what people are saying. OF COURSE it's not unusual that the beta is eating battery life - it seems like early betas almost always have this problem.

It's just that, battery life was a major feature in the presentation. It was expected. Therefore, it's interesting that the first thing the beta does is kill the battery since they talked so much about how it _wouldn't_ kill the battery.

Anyway - just testing out this forum. Not sure I like it. 😁
