This is my second G nexus and it might just be me or it might be the phone but both of them have been horrible on battery, my recent one is better but still not great. A full charge lasts from 6-8 hours. But yet my friends lasts 15+ hours. Ive tried all the battery saving apps and they have not helped. Ive got a battery wall charger and spare batteries so i make it through the day using 2 batteries but its disappointing. Any idea why my battery sucks??
