A magic done by Samsung after update the jan patch my phone battery life was awsome, it takes time to charge 2 hr drain in 3 to 4 hr wonderful, trust samsung and worth to buy like this kind of flagship smartphone.

One of the worst phone i never seen in battery, just 1hr SOT it took 60% of battery life, after the may update I'm facing this issue

Day by day it's getting worst battery performance, 3 times a day i charged, see the sot just 2.48 hours, totally disappointed, 100% waste of money to buying higher end samsung mobiles. they have using good strategy once new one came old one automatic...
