I put an iFixit battery in my iPhone 6 a year or so ago. The battery life was decent but ever since upgrading to the latest iPhone software, well let’s be frank, the battery life sucks! I can barely get through the day! Apple told me to ask the vendor but iFixit doesn’t give any tech support. Is there a battery that can withstand the new update, whether it’s from this vendor or not?
Jacob Crumpley for now use something like 3uTools to check your phones battery status properly etc. After that I would suggest you connect a USB ammeter to your phone and see how many amps it pulls. Also, remember that your personal settings and how you use your phone, greatly contributes to the battery life. If nothing else, replace the battery with a new one from any vendor to see if that makes a difference.
