My iPhone5 was working quite good if I use it rare with rare messaging and few phone calls it was even lasting for 3 days but my regular use was around 1and half day.
BUT 2 weeks ago all of a sudden started to have battery life only for 3-4 hours even not using it. There was definitely no change of my usage of any notifications, location services, push mail etc. but just started drain battery. Only thing I did was downloading few apps recently. (I deleted those apps and did not install them after restores but didnt help)
So I started disabling more services and removing apps but didnt help. Reset settings etc but no way out. After all restored my phone 5 times as a new phone (using itunes few times and through wi-fi the rest) installed few apps only but no way all the 5 restoration did not improve anything.
Last night before taking it from charge turned off wifi and cellular data so no connection could be made from the phone. (bluetooth all the rest was already off). No apps running and no data connection on the phone(left it as a phone for calls and messages only) just standby for whole night and drained the phone to 2% in 8 hours of standby and only 10 minutes of use.So even after restoring it as a new phone and turning nearly everything does NOT help 😟
I remember the good times that seeing 99% even 100% battery waking up in the morning and wi-fi, cellular, push mails etc was on that time.
There is definitely something wrong in the IOS that has been triggered by something and cant be turned off. My last 2 weeks was to read many forums and posts and try what have been told around to fix it and tried all off them before writing here. I will try if I see some other things but from my experience it does not look like a user fixable issue. The bug is deep inside the IOS draining the battery and even resets can not help after it is triggered.
Apple should really come up with a solution to this else iphone5 will not be a mobile phone but more of a fixed phone with limited mobility and need to charge all the time.
Today I have downloaded and the Carat application from University of Berkeley and hoping to see some results in one week time. But since the battery time is not normal I can not use the phone like normal so limiting all the usage on it and keeping it plugged whenever I find a plug, usb port, car charger etc. Anyway maybe this will help to identify the leak.

Hope this will be fixed soon else I need to thrash this iphone and i will continue until all apple products in my family and friends are replaced...
Anyway I am in quite bad position in the last 2 weeks and desperately looking for a solution but nothing till now 😟
