Alcatel Pulsemix battery rapidly draining after WiFi Calling update

[tiredallthetime]

Hi, my mother, brother & I all have Alcatel Pulsemixes from Cricket that we've used for about a year and had great success. After a recent update forced from Cricket for Wifi Calling all of our batteries are intensely draining. We've factory reset, cleared the cache partitions and cached data, booted into safe mode and experienced similar drain, and tried every combination of turning off Wifi/Data when I'm not using the phone and nothing has worked. The last thing I tried yesterday was to turn off the Cell Radio using MMI code and I got an error screen that I haven't been able to get passed. This is the first Android I've ever had so I'm hoping this is just a learning curve but by God this has been going on for a few weeks and I'm at my wits end. The phone's battery life was excellent before, being able to run games and Whatsapp all day long and only needing to be charged at night, versus being charged 2 or 3 times a day now. Any and all help is appreciated.

I had the same problem. My phone was under warranty so I returned it and the new one did the same thing. I called cricket and they said it was Alcatel's problem while I am sure that Alcatel will say it is Cricket's problem

There is a workaround in another forum that will make the phone useable: You have to power up the phone with the battery saver on. This seems to stop whatever process is causing the draining to run.

(1) Turn on your battery saver.
(2) Turn off the phone completely.
(3) Turn your phone back on.

Turning on the battery saver by it self does not work since it does not stop the process if it is already running. However powering up the phone with the battery saver seems to prevent the process from starting.

One problem is charging the phone automatically turns off the battery saver so you have to repeat this process everytime you charge the phone or you have to turn off the phone before recharging.

Thanks so much for replying! I looked my hardest and couldn't find anyone else specifically dealing with Cricket/Alcatel which led to many fruitless hours of attempts.

The only thing I found on my own that helped (not quite 100% of my original battery but damn near close) was going into my settings, under wireless & networks hitting "More" and turning off enhanced LTE services.

Just did the battery saver reboot, hoping it fixes completely!
