Every few weeks a new update arrives on Apple devices, the last one was iOS 10.1.1 that was released on October 31, just 1 month ago. Things are going quite well for us since some users have complained iOS 10.1.1 is causing battery problems on the iPhone.
Several users who have installed iOS 10.1.1 on their iPhone 6 or iPhone 6S are seeing how their device is suffering serious problems in battery life since the iPhone can even turn off when running out of power empty battery.
Drain the battery quickly
A iOS 10.1.1, which came with improvements for the system and with some bug fixes, this serious problem came out a month later. It seems that it doesn't affect everyone but those users who have been affected complain about battery problems.
Some cases mention that the error causes the autonomy of the battery to drop drastically in a short time to the point that the terminal turns off having a 30 % or even 50% battery remaining.

In another case, a user complains that if iPhone has suddenly run out of battery despite having a 60% charge, something that seems to be solved after plugging the iPhone into the current, causing the battery to go back up to 60% weirdly.
It is not known what specific problem could be causing this very serious error in the iPhones batteries. Although the problem arose after installing iOS 10.1.1 the truth is that it could also be a problem with the batteries.
At the moment there is no official solution in this regard or official pronouncement from Apple, so for now we will have to wait to find out any solution to battery problem with iOS 10.1.1.
Have you had this problem on your iPhone battery?
