Lookout mobile Security and drop box.. nothing intensive. However i did research last night and in short, i turned off LTE and NFC... might be a coincidence but im getting triple battery life so far..lol. Check it out below, also haven't got a reboot yet. The night previous i was losing power at night while my phone is idle. I will see how it does through out the day but so far i have 92% left and already surpassed what i had yesterday when my phone was almost dead.
