1 days ago I have bought a new mobile ohone battery of 2000mha power. I charge it 11 hours. But it drains extremely fast. It got 6 month replacement garranty. It drain 50% in 1 hours.
If you would, download two tools and follow their instructions:
1. For monitoring, please download GSAM Battery Monitor and ensure it's started on your phone as you go about a normal day.
2. Find a decent-looking "Battery Calibrator" from the market. Follow its instructions. Something like this may do well:

I'll be frank: I doubt it's software. But, software is cheaper, so try seeing if that works first. The first tool will help you figure out if it's something in the OS that's run out of control causing your issues, or if it's the battery just draining rapidly.
The second will help resolve software problems where the battery and the OS are not communicating well and the OS thinks it needs to turn off the battery much sooner than the battery is actually run dry.
Please report back with your results, including if it fixed your issues. This way, it might help others searching for a solution in future, or if it did not work, we can continue assisting, but such details are important and will help us do so.
If these fail, you should probably replace the battery, ideally with an OEM-certified one.
