I took it to a certified Sprint service center. they re-applied the update using a USB cable. They said it's a more "stable" way to do the update. they also replaced my battery.
still having the massive battery drain issue. if you check what programs are using the battery they are:
based on this alone it should prove it's a "Software Update" issue. Please report this to the software update dept and let them get to work on a fix.
just don't ever say again "Have you taken it to a certified service center?"
we all know the issue. just be honest and say it must be Our Problem and I will do my best to report it to the correct dept and i will let you know when the problem is expected to be corrected.
is that too much to ask?
yes it is to much to ask. more often than not issues that pop up after a OTA could be the update itself..a app that is no longer syncing with the new update..the OTA didnt load correctly. until this is ruled out for each person its a bit of a toss up if its actually being caused by the OTA or not...once that happens sprint and the manufacturer must work back and forth until they figure out the issue and fix the problem...obviously this isnt something that happens over night.
I disagree with your conclusion.
If checking what programs are using the battery shows Android system, Android OS and Google services, it does not prove anything, and certainly not that it's a "Software Update" issue. All it proves that the app itself is not running and taking up resources, but not that there is an app that are constantly calling for these services (or any other battery intensive process.
It is not very likely that something as fundamental as what you propose is wrong with the software. The percentage of people reporting such issues is infinitesimal. They can't all be lucky. For my part, I had no problem, I have over 100 apps installed and I never turn off things or have to worry about notifications or anything. And my S4 usually lasts about 16 hours of normal usage.
My guess is that, most likely, your issue is some rogue app (or updating the app, or integrating with the new OS) is causing the problem. The app itself probably works just fine and never gave you any issue, but once the new OS was installed, the app support data/cache/install settings are no longer stable. The app probably works well both in the old and new OS versions, but nut when installed in one and used inn the other. The combination of other apps may also complicate the problem further.
It is but an easy thing to deal with unless you know exactly what app. Otherwise, you will have to reinstall all your apps from scratch *after* the OS update. Too painful, but might be necessary, and after a while, it may be better than wasting further time digging to find the problem. Maybe before doing that, try to go too every app and delete cache first.
My battery life has not changed at all since this update, what did change was my stock samsung keyboard no longer auto capitalizes the single letter i and i can no longer force a lower case letter after the use of a period. Both so annoying i want to throw my phone regularly 😕
Thanks for looking into this..i did check the auto capitalize setting weeks ago and it was still on, and is still on today. Neither problem is present in any keyboard other than the Samsung keyboard if that helps narrow down the solutions.
Uh, as irritating as this is, i don't have any interest in the hours of work needed to get all my settings just right again after something like that..
Same on my GS4. Battery heating up randomly throughout the day. Battery won't make it to 3pm after previously being able to make it till 10pm. Android System and Kernel all of a sudden the top two battery offenders in GSam, at ~20% each. No way to figure out what is causing the drain within them. Very frustrating.
