So, I have a Sony Xperia C5, https://www.gsmarena.com/sony_xperia_c5_ultra-7463.php, and I went out running in the rain and the digitizer didn't survive. I bought a new LCD on ebay, installed it and everything seems to be working. Well... except the battery. The battery acted fine after the rain and before installing the new LCD. The battery appears to hold charge, but as soon as it gets to 15% it gives me a warning like it usually does, but then dies about 10 seconds later as if 15% now means <1%. IDK, if this means the battery's measurement system is borked, or if the battery itself is. I was considering getting a new battery, but ebay chinese battery's I hear are ify. Again, I'm not convinced that the battery is gone. I think it's just not measuring correctly, and am wondering if there is an app that corrects for this? Or maybe somebody has another opinion.
