Has anyone else been having issues with the battery on their phone since this update mines can barely last a day with general browsing and a few calls (this is with the Wifi switched off and location service disabled apart from one or two apps) when before it would last a full day and have about 30-40% batter left and that was with WiFi on all day and all location services on?

What usage figures are you getting (in Settings)? I'm getting between 8-10 hours before needing to recharge, which seems acceptable as I have wifi on most of the time and have data on only when needed.

I haven't noticed any difference in battery life since updating to 6.1.4.

It says Time since last full charge

Usage 5 hours 2 mins
Standby 14 hours, 42 mins

Is that bad?

Seems a bit harsh.. Turn your screen brightness down if it is up high and if your moving about a city lots turn off traffic in the privacy settings.

yes had issue since 6.1.3 and the same with 6.1.4, did a full restore today to see if the situation will improve will try to report back.

That seems decent to me!

Mine has been fine on all my devices - which is tempting fate...

I do travel across from one side of the city to the other everyday maybe that is it. I just found that Traffic thing what is Traffic for?
