Well, I completed my factory reset and only installed a small percentage of my apps. After a week or so, I'm back to having the same issues, with a dog-a** slow response time for doing anything and everything. Even turning pages/screens has delays. I'm lost............
Sorry to hear about the continued troubles, Nascar. You may need to peel back even the small percentage of apps and try each one at a time. I used battery time between charges to gauge the "greediness" of an app, and did at least one charge cycle with nothing. It's tedious, but right now, I'm leaving my banking app off of the next set of apps I'm planning on installing. The banking app really seemed to suck down the battery.
At 2 days and 13 hours, I'm at 15%. This was with adding My Fitness Pal, adding back my facebook account but leaving sync at Never. Apps were used somewhat lightly, although I had a couple longer than normal phone conversations. Planning on leaving it over night to see if it will die on its own or if the "suspend background data" feature really works. EDIT: at 2 days 22 hours, down to 10%, plugged in to charge.
Meanwhile, I'm moving on to install critical (for me) apps, one at a time. I'm just listing them out now, but will edit this post later to put them in importance order and to list the battery time for each one.
Tapatalk (2d 4h 10% on 7/19, reboot)
Weather Channel (2d 13h 20% on 7/22, reboot before charge)
Drive (already installed, but went to edit a spreadsheet, was prompted to install Google Sheets, used it once. On 7/23 left phone in between wifi and 4g for an hour, was hot.: 2d 2hrs, 10% 7/25. Rebooted, won't use sheets this time)
Paypal (2d 5h 10% on 7/27, reboot)
United Airlines (2d 6h 42m 10%, just hit that level, 7/30, reboot)
Amazon (1d 17h 10%, didn't use Amazon much, during visit to gym last night, phone was bouncing between wi-fi, 4g and 3g, noticed very sluggish behavior then)
Photobucket (1d 7h 15%, on 8/2, had to charge "early" as busy day next day)
Break - this next charging cycle, I won't use many apps, just rebooted the phone during recharge. Previously I would start all the apps above, use the latest one a little, and at least start all the other built in apps I use. This time I want to see if I don't start any apps if it has any effect on battery life, in other words, how much battery do these apps use just being installed.
UPDATE: 3d 0h 56m, 8/6 got the 10% "burp-burp" noise. Haven't rebooted yet, here were the apps that were on during this charge cycle:
Text
Camera, Email, Calendar, Gmail, Keep, Browser, The Weather Channel, Phone, Tapatalk
Don't use apps, battery life goes up, film at 11! However, if I don't want to use apps, I'll go back to a flip phone. All that said, I noticed some sluggishness with the phone last night using text and the screen unlock got hinky as well. Just the one time though, bears watching. Will now reboot phone and continue with the app installs and battery watching.
Ebay (quick note 1d 2hr, 20%?!?! lost previous note, I think 10% burp happened 3 hours later)
Astro File Manager (1d 13 hr, 20%, need to charge early, also added Google Authenticate and some barcode scanner utility Google recommended, due to iPad arriving)
K-9 Email app - added three email accounts, forgot to restart all apps. At 2d 10hr, got 10% burp-burp on 8/12. Apps that were started: Text, gmail, email, K-9 mail, Browser, Camera, Weather Channel, Phone, Google, Keep, Authenticator, Contacts. Had a 45minute conversation on bluetooth.
banking app - 2d, 1hr, 30 min 10% burp. Started all apps on this last cycle, didn't use much, though did score some sweet MC gear using Tapatalk and Paypal. 1-2 hours of talk, no bluetooth.
