Battery drain faster after udating to iOS 8.1.2 ( iPhone 5s A1530 16GB )

OK.... I've been experiencing the same extreme battery loss as everyone else since 8.1.2 upgrade over weekend. My IPhone 4s was just fine until the upgrade. Since the battery did not have issues before, I don't believe the hype about 'get a new battery'.

BUT...I full-charged it to 100% at 1:05pm and it's more than 2 hours later and I'm still at 100%. I'm not using it (standby) but at least the battery charge is not dropping rapidly either. But, I had to turn a lot of features off to save the battery.

Turned off WiFi, bluetooth, cellular data, background app refresh and location services. I guess I'll just have to turn those back on if I need to use it. This is kind of a crappy alternative but at least it will be there when I need it. Being shackled to a cell phone charger or a totally dead phone is much worse....

Apple - Fix please your software....

Since you've restored the phone without backup what I would do next is take the phone down to its bare bones including deleting all apps. Go through every setting there possibly is and turn off everything. The idea is to eliminate anything that might be using CPU cycles which includes background refresh, push notifications, email, even turning off cellular and wifi. Charge the phone up over night and test the phone the next day and see how much the battery drains. If its the OS then you likely won't see much improvement. If the battery performance improves however and appears to be what it should be then start turning things on bit by bit and reinstalling apps one by one. The idea is to find the culprit(s) causing that is batteries to drain fast. I should also mention that when you reinstall the apps download them again rather than from a backup in case one of them is corrupt. Good luck with it.

UPDATE: Almost 5 hours later and I just now dropped to 97% battery....seems like the good old days! 😉

Hello everyone. I'm from the Russian community 4pda. On our iPhone 5s 1457 after upgrading to 8.1.2 tnablyudaetsya sillny battery consumption. Battery life time is equal to the active use of statistics. Phone lain all night after a full charge and disappeared 20% of the battery, the statistics indicated that 6 hours is used. On 8.1.1 was no such problem. I have a new battery has 300 charge cycles. The problem occurs if the device to flash through the DFU mode.

According to the recommendations disabled icloud on the phone - the problem is relevant.

Apple fix pls battery!!!

Apple just does not care, they know the problem but they can't fix it and they don't come with a solution.

It's just ridiculous to ask people to turn of all the utility's on your phone, It's like buying a Ferrari that after a motor management update doesn't go faster then 50 mph and then ferrari tells you to turn off the Radio, Airco and Nav and then you can go up to 80 mph. Dear apple, I want my iphone to go 200 mph again!!!

But what I think is the worst, Apple and his community laughed at Microsoft for 30 years, but now their software is worse then windows 3.11

The problem is the APPLE IOS, I did all that and after a factory reset without installing anything it drains in 4 hours to 0% in standby.

Their is no solution besides Apple hiring some people from Microsoft to solve the problems, APPLE and IOS are worse then Microsofts windwos 3.11 and Vista together, it's a joke and the worse thing is that apple acts like the problem does not exist, the don't mention the problem at all.

Like i say, APPLE BECAME WORSE THEN MICROSOFT HAS EVER BEEN

I Am facing issues with mh iPhone 5. Since recently (4-5 days ago) the battery started to drain significatly faster. Especially if I am using the camera. Today the battery was about 50% and it collapsed.Could it be the battery problem. I have reinstalled the software from the scratch twice.

Please help with some ideas what to do.

Restore as a NEW device (don't load your backup file) and test to see if the problems are resolved. If they are, that means it's one of your apps or something in your backup file that's causing the problem. You can sync your content & apps back manually if that's the case.

I did restore as a new device. But it doesn't work. My device is iPhone 5!

Without restoring your backup file?

I Made the same decision, finally I restored as a new device, and the battery issue still there.

MAn this problom is with this creepy 8.1.2 update nor with bettries so wait for the next update we are also iphone 5 users so stand in the line as we are till next update will appear with this bug fix

I would just suggest to shut down you phone, leave it off for a few minutes, then power it back on and see if notice the same heating and battery loss (give it a few days). After this, I would go to an apple store so they can run some diagnostics.

P.S. If you want to turn off background app refresh (you may not notice, but apps are working in the background), go to Settings > General > Background App Refresh > uncheck any apps you want, and as you can see in the description of the refresh page it says that it can preserve battery life. You might be surprised by all the apps on that list!

Hope I can help!

e thing is that I have tried everything. What seems to be the problem is not the battery drain itslef....the phone is working like crazy.....it doesn't show any battery drain and it icenetly shuts down. Then on I plug it to the charger, it immediatly show 30-40% battery
