So how do i fix the battery?so it lasts longer.what settings
Abnormal. I haven't even reached for a charger since I got the phone. Battery is far better than my Note 5 when it was brand new.
I just leave mine on mid range battery saver. Lasts all day.
That is always a tricky 'unanswerable' questionWhich apps are you running? Any unusual apps that are being reported by the phone (it monitors apps that consume out-of-the-ordinary amounts of battery a day and displays a 'warning')? How many accounts you have syncing and how many are push VS polling (the latter will drain more)? Are you using the screen for how long? Full on brightness vs auto mode vs low brightness? Battery saver mode enabled? (See why this is 'unanswerable'?
)
On mine, with MY apps, Sync active on two e-mail accounts and social media, mid-avg use, auto-brightness enabled, no battery saving modes, the phone will make it through a day with at least 20% left to spare. I'm getting much better battery life with this one than what I was getting with an S8 (not the plus, normal one). But again, that's MY usage.
That being said, 7 hours of use, unless it's super intensive, sounds abnormal. Most people I've heard about are getting stellar battery life.
I dont know how to tell if my new phone is broken or not?how can i fond out
First of all, SOT is not a good measurement for how much battery last, it can be fooled easily, aka I can put the phone on one app and leave it idle till i get bored, and SOT will skyrocket.
But if u use the phone with various apps, such as browsing the web while listening to music and doing other stuff, it will get down quickly, also depends heavily on brightness level and singal transmission strength.
I would suggest downloading GSAM monitor and see what app sucking your battery, sometimes when u use 4G outside, quickly toggle the airplane mode on and off to reset the radio, it might improve signal.
Do it, that will be a good start to know what's happening behind the scenes.
I browse the web wilst lisining to music alot with my headphones
