After the latest iOS update (8.1.2) my battery drains in 4-5 hours, on standby (5S 16gb) - and I'm not the only one

Question

Hello,
Since the latest update, my iPhone 5S's battery life has decreased significantly.
In the past, I've never ran into any issues. I have my 5S for over an year now.
Prior to the 8.1.2 update, a full battery lasted for about 24h (usage time >= 4h) to 50-60 hrs (on standby, no usage).
However, after updating, I can see my battery decrease in an alert mode ( about 2-3 % every 3-4 minutes, even on standby).
I've tried all the solutions possible, including but not limited to:
- downgrading to iOS 8.1.1 (I managed to do it, because Apple is still signing the IPSW files). - didn't work, no improvement
- restoring and updating again to 8.1.2 , starting from scratch (I've backed up all my stuff first, restored, updated, set iphone as 'new' , didn't put my data back on) - didn't work, no improvement
I've also chatted with the tech support today and they diagnosed my device, saying:
Quoting support operator:
"Good news, it seems that everything for the hardware side —WiFi, Cellular, and Battery is looking beautiful! That is awesome! Some of the software though does seem to be affecting some things I do see. So, we have found out what the cause is. Next step is getting it taken care of so it doesn’t continue. I want to make sure you don’t have to keep worrying about your battery life."
The only fix they offered was restoring and updating to the latest version, 8.1.2 , again. I've told them I've already tried it, but I thought to give it another try. Unsuccessful again, battery still draining quickly.
I've discussed with another operator about 7 hours later, describing my problem and also told them other users experience this issue too:
Iphone iOS 8.1.2 battery drain remains
No iOS 8 Battery Drain Problems Until iOS 8.1.2
These are only two topics I've found on apple support forums, but many others are experiencing this too.
The technical support employee told me that Apple didn't yet discover this bug and if they do (on a large scale) they will issue an update, or a fix.
That's why I ask you all who have this issue to come and post here, to let Apple know we want our devices to work normally again.
I can't use my iphone if, it drains 100% of battery in 5-6 hours without abnormal usage time!! I also don't think it's healthy for the battery to recharge it 2-3 times a day.
Something needs to be done. I regret every day my decision to update to this version of iOS . I will never update again prior to reading other users' experince on the update.
Please, Apple, do something!
Oh, and by the way, I would go to a service to have this looked into by a specialist, but in my country (and I'm sure there are other countries too) there aren't any Apple services , only shops. And I can't risk taking my phone to a local GSM repair shop, I don't trust them.
Hoping for the best,

I Have the same issue on a brand new iPad mini 2. My battery is only lasting up to 5 hours. I went on chat with Apple last night and they said my battery is fine and its a Safari issue. I'm literally losing 1% every 3-4 minutes. I tried recalibrating my battery, signing out of iCloud, shutting off all locations, turning off background app refresh, restoring network settings, restoring all, and finally restoring from iTunes with no luck. This is just awful. I got this iPad so I could use it on my long flight for a trip I have coming up, and unfortunately, it's not going to last that long, plus I'm concerned about how many times i will be recharging my battery because of this since battery's do have a life cycle dependent on the number of charges. This is frustrating and needs to be fixed ASAP and addressed by Apple.
By the way, Apple told me to bring my device to the Apple Store because it's still under warranty. That's great and all, but I'm going to waste my time if there is no fix for this issue.
Ok so you want Apple to address the problem, but yet you don't want to take it to them just in case they can't fix it? What if they can fix it? Complaining here certainly won't fix it.
