Hello all! I've been reading through this forum and I've been having questionable battery life on my X.
Here's some background: I received the phone on launch day and I set it up as a new phone (I expected the battery to have to settle in but it hasn't changed much for me.) I have only a small, core amount of apps I keep on my phone, and I usually keep the screen brightness on the lower end at the bottom of the sun design.
I'm not what you would call a "power user" I'm usually using Messages mainly, checking Twitter and Instagram about once an hour and occasionally on Snapchat and every now and then checking emails.
I updated from a 7+ and would regularly get between 8 and 9 hours of us usage with a standby of 22hrs-1 day+
I've been disappointed with the battery life on the X, getting on the lower end of 6 hours of usage when I get to 1% with standby of about 14-16 hours. This isn't bad but it isn't great as I do have longer than usual days with school and work and I travel often with long days on the go with really no access to charge.
I miss the battery life on my 7+ because it seems like it would be better at managing how I use my phone. I could wake up and leave my house around 7am, use it on a heavier than usual basis say on a Friday for work and school, then meet friends out at happy hour around 5:30p with about 60-70% remaining.
I know this message is tedious but could it be there are some faults in certain batteries? I don't use bluetooth, usually I'm on wifi, background app refresh is off, mail fetch is off, app updates are manual.
I'm thinking a trip to Apple is next

but I don't like being that paranoid iPhone user always at the Genius Bar.
