First of all, sorry for openning a new topic about note 5 but I couldn't find one for battery life.
I got my phone 2 days ago, did back up some apps, phone contacts etc and got the latest ota update. Everything was fine until I went to sleep. I charged my phone to 100% and went to sleep around 11pm, when I woke up at 7 and checked my phone, the battery was down to 70%. Everything was off like gps, bluetooth, nfc, gesture except wifi was on. One more importing thing, my normal power saving mode was on all night, so how could this possible? 30% down in 8 hours without using it? During morning and afternoon with some light use (screen on only 20min) my battery drops to 48%. This is so frustrating and kind of unusable. Please can Rogers check it asap? I like this phone don't get me wrong but with this battery life, its a big no no.
Take a look in Settings > Battery. You can tap on Battery usage to see a list of what is draining your battery. If you go back to Settings > Battery you’ll also find an Abnormal battery usage section that should highlight anything that’s guzzling too much juice. If there’s a problematic app, then consider uninstalling it or restricting it.
also, battery recharging is even less of an issue, because the Galaxy Note 5 charges faster than previous Samsung phones. The Samsung's Fast Charging standard can fully replenish dead the battery in 1 hour and 20 minutes. Plug the same Note 5 in a normal USB charger and it takes 4 hours and 20 minutes.
