    About a month ago and this may have happened with the last update, I started having WiFi connection issues. Basically my phone no longer connects to certain WiFi networks that I use all the time and if I do not turn WiFi off my phone doesn't work at all for anything other than phone calls. No text messages, no email, no internet...

    Also my battery started dying quick. I used to be able to charge all night, unplug around 6:30am and it would last until bedtime. Now I have to charge multiple times per day. Sometimes the phone gets super hot and I can lose 25% battery in 10 minutes until i yank the battery out.

    I now have to keep WIFi off and keep the phone tethered to the wall plug.

    Does anybody have any suggestions. ? I didn't do a factory restore yet because it's a royal pain and from past experience it rarely changes anything.

    Thanks. !!

    I use a 16 GB SD card and I am using that instead of the internal memory. If I use phone memory and my phone takes a crap I still have everything on that card.

    The problem is that if the SD card is corrupted it can cause serious battery drain. I only suggested that as a test. Another possibility is your router. I have some suggestion in a link, below, on possible solutions.

    SD Card

    Sure enough everything works without the SD card installed and it seems that the battery bleed has slowed.

    Do I just replace the card or is it a configuration issue. ??

    I would copy the data somewhere and try to reformat the card in the phone then copy the data back. Glad you got it figured out.

    Also possible that it wasn't really a problem with the card itself, but when you removed it then some app that had been causing problems and depended on the card being there could no longer run. An example is an app that does periodic backups to your SD card. I have several - a postit app and a password app. If they went to check on the date of the last backup file on the card and were having trouble doing that, I could see them looping - then when the card is removed they would calm down. Just speculating, but possible. You could also have a bad card, have a good card that is somehow corrupted and just needs a reformat, have some type of permission problem in the directory structure, or may even have an issue that would be cleared by re-seating the card. Your first step may be to copy the contents to another card and try that. You would do this on your PC, using a USB reader. If you buy a new card, it always pays to buy a good one - I will only buy the fastest Sandisk card my phone (or other device) will accept.

    Spoke too soon

    Well I spoke too soon. It worked for a few hours now I'm booted off wifi cannot get back on and I can litterally watch my battery life drop. I lose a percent a minute right now.

    Whatever it is it's obvious the battery and wifi problem are related.

    Could be both. You could try a public WiFi hotspot out, That could eliminate one of those possibilities. Or try turning WiFi off for a while to see if it changes.
