Since receiving the update on my Samsung J3 the other day, I have noticed my battery drains a lot faster than what it use to. My 5 year old watches a lot of YouTube on my phone (at least 5+ hours a day) and my phone would last at least 75% of the day. As of today, she watched YouTube for approximately 1 hour and my battery is almost drained. I took my phone off charge at 10am and the battery was 100%. I checked my emails roughly 5 minutes and my battery was at 94%. I left my phone in the house while I went out to work in the yard and did not pick it back up until 1:53pm and sent a message to a family member. My phone then was at 75%. My 5 year old picked up my phone at 4:12pm and watched youtube until 5:03pm. I then picked up my phone at 7:07pm and my battery was at 26%. I dont think the update is battery friendly. Any thoughts?
