battery drain IOS 9.0.2

I suggest you log an incident call with Apple.

i have the same problem, iphone 5s with 9.0.2 and the battery went from 20% to 3 % right in front of my eye while using it!

Logged the call and ask to restore 9.0.2 which I did but today its still draining to fast and jumps, so for example was at 45% for ages while using it. stopped using it a few minutes then picked it up and it went to 33%.

I think there is something wrong with the algorithm that they have used in the 5S, that or the a/d converters that work out the battery volts has a glitch with the new software.

I down graded to 8.4.1 and it worked fine, but now I tried 9.0.2 again the fault is back and now I can't downgrade as apple have stopped singing it.

I'm due a call back today from apple support to see if it is fixed so will be telling them NO its not.

I'm seeing significant drain too on my 5S and my (possible) replacement 6S. I was getting horrible drain which stopped as soon as I signed out of iCloud.

I've just noticed that my iPad air 2 is also suffering from this, with usage and standby times being the same. I've watched two videos this morning which should leave me down in the mid 80% region, but I'm doing at 64%. iPad claims 2.4 hours usage, but I only watched 1.5 hours of video and thats it. I really don't want to have to sign out of iCloud on that device as well.

Any luck since posting?

Just got a 6S and noticed that the battery was draining even when not doing anything (no push, almost no background activity). Installed the same App and have the exact same results.

Thanks!

Hi. Try to follow the instructions on this page in order to maximize your battery life:

Try to reset your device. This won't delete your data stored on the phone.

• Press and hold the Sleep/Wake button
• Press and hold on the Home button
• Keep holding both buttons until the display turns off and back on with Apple logo on it.

You may also try to reset all settings: go to Settings - General - Reset - Reset All Settings

You may also try to follow these steps:

1. Navigate to settings/general/ battery usage. Check the applications. This will show you which app eats up your battery.

2. Turn off iCloud keychain: Navigate to Settings/ iCloud/Keychain / turn it off.

3. Limit apps activity on the background: Navigate to Settings/ general/ Background App refresh/ turn it off for each application which uses to much power.

4. Disable auto brightness: Navigate to settings/ display and brightness/ auto-brightness. Turn this option off.

Ho lo stesso problema da quando ho installato l'aggiornamento 9.0.2 sul mio iPhone 6, la durata della batteria è passata da 30/40 ore in standby a 7/8.

Su consiglio telefonico del Customer Service ho inizializzato il telefono e re-installato tutto, senza ottenere benefici.

Dopo due telefonate e due visite al Genius Bar, per la mia insistenza mi è stato sostituito l'apparecchio ma tutt'ora permangono i problemi di durata della batteria, inoltre il telefono si scalda parecchio.

Se verificato il tempo di utilizzo del telefono equivale a quello dello stand-by pur non avendo fatto niente.

Questa mattina ho installato l'app Bactery Doctor e mi da una videata identica a quella di kege111.

Vorrei poter disattivare queste app che effettivamente non utilizzo e poter riavere il mio telefono pre aggiornamento.

I have the exact same apps draining energy. Seems a strange coincidence? Maybe the app doesn't work right. In any case, it would be nice to know how to shut down these apps.

Buongiorno a tutti,

Ieri ho installato l'aggiornamento iOs 9.1 e sembra che al momento i miei problemi siano cessati.

Battery Doctor segnala ancora il consumo eccessivo di alcune app e rimane il problema di poter cancellare quelle preinstallate.

Same problem here and the same apps apparently using excessive power (except for the Chines one). Find my Friends being the biggest power hog according to the battery app.

Next to replacing the battery three times, I also tried every trick in the book to stop the draining. Reset, reflash from DFU, update to 9.2 beta, new/other Apple ID....it just does not matter. Battery drains from 100 to 0 in about 6 to 8 hours (max) with power save mode enabled, flight mode enabled and in standby (not in use). Even in the setup screen (Hello...) and on standby the battery drains in 6 hours from 100% to 0% (with and without wifi, with and without SIM ... it does not matter).

Phone was OK untill the update to 9.1 ... now it is totally unusable.

I HAVE THE SAME EXACT PROBLEM i've tried every single trik to get rod of this problem to no avail.

Same identical issue !

i initialized the phone like a brand new iPhone and i solved the problem 10 days ago , yesterday the problem appeared again !!

stesso identico problema !

avevo formattato e andava tutto abbastanza bene ( non avevo fatto il recupero da iCloud .. configurato come nuovo iPhone)

ora è ricominciato di nuovo il problema da ieri !
