Hi, OK, so i'm pretty technical. (actually its my job) and this one has stumped me a little. My 6S 128gb on the AT&T network is acting all weird. Like pausing to bring up stuff and burning thru battery like no tomorrow. Already at 65% this morning. Also when sending iMessages, sometimes the reply bar takes a few seconds to appear. Sometimes it takes forever to send a message. Also my Apple Watch is struggling to stay in sync with the phone. Example i may receive a message on my Apple watch and it not appear on my phone, or if someone calls me, the phone rings and i pick up, but the apple watch stays ringing. So I've reset all network settings Made sure nothing is running in the background.. As in double tap and close any apps in the background Disconnected from the wifi, (which i thought was the initial problem as in the hotspot playing up) deleted my entire history of imessage and sms. I'm about to reformat the damn thing, but that's a performance in itself, to get all my music back on the device. The only weird thing is that My battery settings are saying Mail - Low Signal 67% used. So its as if the phone is working overtime to get email. (according to that diagnostic screen) I guess i could delete the accounts and re-create them. Nothing has changed with my email settings. Really asking if there's any diagnostics i can run that'll at least point in the right direction. Other than deleting my mail accounts and re-creating to see if that fixes.
