Note 3 Exynos - Battery dying even on standby
I bought my Note 3 in December from a Samsung Smart Cafe. The phone was amazing throughout the last few months. 2 days on medium usage, amazing WiFi connectivity, awesome gaming experience.
However, 3 nights back I had left the phone (at 50% battery) and gone to bed around 23.00 hours. The next morning I woke up late at exactly 10.00 hrs. When I went to check for any missed calls I found that the battery had completely drained off and the phone was dead. I turned it back on t see that the battery percentage was 1%.
I want to clear out that the following are deactivated on my phone:
2) Wake up in lock Screen
When I checked the battery stats I found that the screen was using 56% of the battery. How could that possible be when the screen was switched off the whole time.
Since then every night there has been a drain of about 46% every night. Earlier it used to be only 2-3%.
Could you guys please help me out here? Really tensed
P.S: Last night I left the phone on flight mode and went to sleep. The battery drain was only 1%.
