Hi all, I was having some problems with my phone and was wondering if you had some solutions. So my phone's battery has been on its last leg for a while, and today I noticed that despite having it on the charger, the battery was still going down. I replaced the battery and it kind of worked? This brand new battery is going down about 1% per minute and after having it on the charger for 3 hours it just didn't go past 26% while off, and after I turned it on it started charging past that. This new battery is still dying very fast, I did the math and it should have about a 3 hour battery life, which is not good. Anyone have any idea what might be going on?

Phone is a Samsung Galaxy S4 mini, a low end phone from a few years ago.

Thanks in advance for any help!
