I do not know about the Blackberry, but I suspect it does as well.
Plan to charge your phone continuously during this period of time."įrom what I hear the same issues occur with all Android and iOS phones. The "update complete" message needs to include a message that states, "Expect heavy battery usage to occur for the next 1-3 days to complete additional update operations. The update finished after about 2 days for this past weekend's update. Sprint’s version of the update (build number G920PVPU3CPB6) is the same as the one that has rolled out to the unlocked Galaxy S6. The Galaxy S6 edge is probably getting the update too, but we don’t have a final confirmation on that just yet. When we turned the network (voice) radio back on without data mode enabled, the battery drain began again. Sprint is doing so today, with its Galaxy S6 beginning to receive Android 6.0.1 over the air. How did I figure this out? When the battery was draining, we turned off all of the radios (airplane mode) for about 30 minutes. I suspected and confirmed that this background update was sending the update files through an "over the air" channel, not the data channel nor the WiFi. I spent 3 hours on the phone with the lead technical person and they did not know what I am about to explain.Īfter the "Update Complete" the drain on the phone battery will occur at a rate of about 8% per hour and continue until the background update completes. That is just the beginning of the update. When the message appears stating that the update is complete, it is what we call a "white lie". The update that you see takes around 10-20 minutes and reboots your phone a couple of times. While we all know that radio usage drains the battery, there are some operations that you cannot see on your phone. The "optimizing" descriptions and everything else claimed to be the source of the problem does not align with my actual findings. The time of the drain varies from 1.5 to 3 days depending on the size of the update. This is when they removed the requirement to have your phone charging during the update. On the Galaxy S6 that my wife has, she noticed massive battery draining to occur after software updates beginning with the June time frame update of Android and continuing with every update that followed.
However, the problem isolation skills apply and here is what I have found. From a credentials perspective, I have been a software engineer at the kernel level for many operations, but not Android or Linux.
