Do provide a list so we can help.My battery drain has been crazy bad recently and, while I use some of the features of JB, curious if I should move to 7.1.1.....I understand I would lose JB for good but it's gotten bad. Thanks.
You can use Activator (and IFTTT) to automate stuff in order to make life easier *and* safe battery.
Activator example: disable data (or just 3G if your iPhone has no nasty 4G toggle) when connected to Wi-Fi [and turn it back on when leaving Wi-Fi network].
IFTTT + Activator example: receive IFTTT SMS at sunset & sunrise, use Activator to link F.lux to the SMS so it does not run during the day.
