S23 Ultra battery life not as good

[Rahulrajrai]

Hey guys, I don't know what's wrong but I never ever have the advertised battery life with any devices that I own. 

My battery level at the current moment is at 84% and when I go to details, the sum only adds to 9.3% meaning I'm missing a 6.7% in battery capacity at the moment. I've always had this issue with my older devices too. My friend who got the same phone has way better battery life. At first I thought it was an issue with one of my apps so I reset the whole phone and didn't use smart switch for anything except contacts and SMS. 

Any ideas? Only thing I can think of is that it's my Bluetooth antennas draining the battery cause I also have galaxy watch and buds pro.

Advertised battery life, is kind of similar to what Auto Manufacturers say about fuel mileage. It's typically calculated using the best possible conditions, and generally it is never achievable in "real world" usage.

Denying apps permissions, to continuously run in the background, and always be "refreshing" data, is one effective way to improve your battery usage.

*Your mileage may vary 😉

I agree man, but I've a friend with the same phone and he has better numbers. Only difference between me and him is the Bluetooth thing..or maybe even GPS cause I drive and use android auto

Unless the two devices have the same apps, usage, location, network connectivity, settings, you can't really reach any conclusions regarding the battery. There are simply too many variables. 

Things as "invisible" as which apps have location permissions, could have an effect on the battery. 

I really wouldn't worry about it.

Agreed 100%. Unless you calibrate both phones as much as possible, too many variables. Compare these other settings on your friend's phone against yours:

- Wifi, BT, Location, NFC, Mobile Data (which are concurrently on)
- Ultra-Wide Band on or off
- Adaptive refresh rate on or off
- Screen brightness level
- Screen Resolution
- Network Connection max (5G, 4G/LTE, 3G, etc.)
- Dark Mode or Light Mode
- Processor Speed - Light or Optimized
