Hi veeko
I'm sorry to hear your not enjoying your experience with the Samsung Galaxy s6.
Their are lots of battery saving tips if you carry out a Google Search.
One tip is to close down Apps your not using.
5. Switch Off Unnecessary Features & Apps
turn off apps and features that consume battery and are not in use all the time such as Bluetooth, Wi-Fi, Smart Lock, NFC, GPS, Sync, Location, Google Now.
6. Go For Grayscale
Turning on grayscale on your Galaxy S6 will help preserving battery life since the phone will consume less power. To do this, tap on the home button three times for reduced power consumption.
Navigate to Settings > Availability > Direct access > Turn Gray Scale on.
4. Opt For Power Saving Mode
The Galaxy S6 packs in the Power Saving mode and Ultra Power Saving mode. Using either of these options will allow the device to last longer.
The Power Saving mode basically reduces the smartphone's vibration, CPU speed, brightness of screen, and display frame rate automatically, so that the battery life increases. This feature can be deployed if you're starting your day and know that you're going to be on the move and usage will be quite heavy throughout the day.
The Ultra Power Saving mode, on the other hand, comes in handy when the Galaxy S6's battery is close to draining out and the user has a while to go before they can get hold of a charger. Switching to the Ultra Power Saving mode in such a scenario enables the battery to last for nearly 24 hours on just a 10 percent charge. However, usage is limited. One cannot run third-party apps when in this mode.
3. Go For Black Wallpaper
Another effective way of reducing battery drainage on your Galaxy S6 is by using a black wallpaper because the smartphone's AMOLED screen is power hungry.
1. Switch Off VoLTE
Users in regions where VoLTE support is enabled for the Galaxy S6 would do well to switch off the function. Why? A bug in the firmware causes VoLTE to drain the battery of the Galaxy S6. While you're at it, ensure you turn off Smart Switch as well.
Navigate to Settings > Wi-Fi > Smart network switch > Off.
