2 issues since 5.0 update

[Lordnik95]

I updated my One M7 a couple of weeks ago and ever sense I have had 2 issues.
1. Everyday my wifi will not connect automatically to saved access points. I tried turning the wifi off and back on, but it usually freezes. I have to power off the phone and turn it back on, then turn the wifi back on and it will connect. This occurs once a day.
2. My battery does not seem to accurately reflect how much power is left. I am not a heavy user by any means but occasionally with all of the rebooting of the phone it will start out at 50% but then magically be less than 15% after a reboot.

Any thoughts?

Welcome to Android Central! Have you already tried a cache partition wipe? https://support.t-mobile.com/docs/DOC-6526

Cache partition wipe does not seem to have worked. It just happened again where it randomly wouldn't connect to wifi until after a reboot by which I mean I actually selected power off, not the restart option.

Ok, next thing to try is Safe Mode, in case some 3rd party app is causing some kind of instability. See the steps at the bottom of this article: https://support.t-mobile.com/docs/DOC-6526

Thanks for your suggestions. I tried this, too. Still had the issue yesterday twice and today. Really not sure what's going on. Haven't been able to find anyone else having this issue. Guess I'll just live with it till I get tired of it enough to upgrade.

If it's happening on Safe Mode, I'd be concerned about some glitch in the actual firmware. You could try reflashing it via Odin: http://forums.androidcentral.com/am...w-flash-stock-rom-via-odin-new-interface.html. Find the proper firmware here: Firmwares - SamMobile

There are reported wifi issues with Lolipop 5.0x. 5.1 is supposed to fix them and unless you can revert to an older OS you may have to wait for the next update.

A factory reset often fixes battery drain issues that crop up with system updates. The reset removes all the junk left behind by the previous OS. But, it's a pain to do as you have to set up your phone again from scratch.

this dose not factory wipe your phone right?

I'm actually not sure if flashing the firmware via Odin wipes the phone.
