I got my Samsung galaxy note 3 on 24th December n the battery life was OK. Just yesterday it started draining quickly. I charged it to full yester night before sleeping. Woke up this morning and it was left with 60%. I was puzzled. Checked and the screen was using about 38% and Android os 27%.please what can I do to help my battery stay on longer. Any help will be much appreciated. Thnx
