Hi, The main reason I purchased iPhone 11 Pro Max was because my previous device iPhone 7Plus battery drained fast and did not give me the promising usage! You couldn’t do anything with 3 hours of battery life! I also found other bugs, but not as severely as battery life issue. Now my current device is facing the same issue. After each software upgrade, the battery drains faster! Nothing compared to iOS14 a LIFE SUCKING HELL OS, It drained my battery within 3 hours even with minimal usage (play music via bluetooth connection, check workout programs online) and my battery health is at 97%! The reason Apple gave us for the cause is to prolong longevity of the phone. This is A BIG BS! Then if you want to push clients to keep changing their phones every year or two, this is a wrong tactic! We expect the phones to perform better and last longer (money’s worth). We expect the phones to be our daily driver and be utilized to fit our demanding lifestyle! PLEASE FIX THIS ASAP! You will continue to lose the battle to Android and other giant phone companies! If nothing fixed, I will need to shift to Android and say Goodbye to all Apple products I currently own including Apple Watch and Macbook. You can MORALLY DO BETTER Tim!!!!!!!!!!
