[X Style (Pure) General] acejavelin:
Just an FYI... Up until a week or so ago, I was averaging 2h 45m to 3h screen on time in an average day and since I started using my phone for work (BYOD program, always had a separate work device before) the battery life started really mattering so I made the following changes...

- Dropped Facebook and Messenger (MASSIVE battery hog apps, always at the top of the list) and moved to Facebook Lite (yes, you can get it in the US, just have to use APKMirror, and it includes Messenger services in the same app)

- Dropped Accuweather (was keeping device awake and accessing location dozens to hundreds of times per hour) and switched to 1Weather

- Dropped Microsoft Outlook (keeping device awake and using background data, and a Device Administrator I didn't want) and switched to Nine

- Dropped OpenSignal (was using background data and waking device very frequently)

- Disabled Moto Display entirely

- Disabled Moto Action Wave to Wake

These 6 things are all I have done... I keep all services active, high accuracy location, all accounts and services syncing, no background data restrictions, no disabled apps, backup and other services like Motorola services all running, no adjustments in permissions, using Gboard as my default keyboard, and I have ~120 apps installed, 80% of which are occasional use only. I use a Quick Charger about 50% of the time for boost charging at work or when traveling, but overnights it is on a standard (5v/1.8A) charger and not QC. I have seen my Doze and Deep Sleep times increase significantly, with Deep Sleep time approaching to 75%... And Screen On Time over a normal day increasing by nearly an hour on average... In fact, yesterday I had my best SoT in over a year with 4h 28m over a 16 hour day in mixed use, including a 6 hour YuGiOh tournament where I used the phone to keep score of my matches (with marginal LTE service and no WiFi), going out to eat 20 minutes away, and then back home for some video game time with friends and still have 20% battery remaining when it went back on the charger, probably could have gotten 5.5 hours if I pushed it near zero. Making it sufficient for daily use for me again.

Am I saying this is the answer for everyone? No, but install a good battery monitoring tool like GSAM Battery Monitor and see what is using your battery (make sure to enable advanced reporting, requires ADB connection)... and don't just look at the default screens, dig into the app after some use. The "View % Power Used" screen only tells part of the story... Make sure to look at View Number Times Waking Device, View GPS Time Used, and View Time Held Awake because some things are not always so obvious. Accuweather for one was "hiding" some of it's usage in Android System and Google services in the View % Power Screen, but when you looked in View Time Held Awake and View GPS Time Used, it became evident it was doing something.

Some other apps which can be culprits are shopping apps, they often track where you are frequently... such as Walmart, Sam's Club, Best Buy, CVS, and most other dedicated apps for shopping. Alternative messaging apps like Messenger, Whatsapp, Kik, Skype, Viber, SnapChat (currently the #1 battery killer out there according to several sources), etc. often keep the device awake and use background data. Airline and other travel apps often check your location every minute or even more frequently even when not open. "Optimizer" apps like LionMobi Power Battery, CleanMaster, and similar tools are worthless and usually consume more resources than they help with. News apps like BBC News often use background data and keep the device awake... Some of these apps might be worth it's battery consumption for your usage, maybe not, the point is to know the problem and decide if it's needs to be fixed or not.

All I am saying here is that before you blame the device or hardware, make sure it isn't your software or usage that is the real culprit, but sometimes it does take some digging.
