I have an unsupervised Windows Phone device connected to a 12 V battery -> cigarett socket -> micro USB. I would like this phone to notify me when the 12 V battery dies, i.e., when the phone's internal battery starts to run out of juice.
The device is connected to internet but can't send texts (but it can make phone calls with caller ID).
Are there any apps that can send an e-mail, make a a phone call (but not in the middle of the night) or similar when the battery reaches a certain level?
This can be done with a custom app that doesn't use the built in phone email function I believe. I use the below vode in my .net desktop apps and i think similar will work on phone. But I don't think battery percent is available in Windows Phone 8. Only 8.1+. In Windows Phone 8 you can only detect whether it's charging or discharging iirc.
You can have the app query battery percent and then send an email via google or something. You an also email to text message. I'm writing this in my Lumia so excuse the formatting. I'm sending to a tmobile text recipient but I know the servers for major us carriers. Or we can send it to regular email recipient.
This example uses a Comcast server but should work for any provider you have info for. Vb.net
Dim txtmsg as new MailMessage()
Txtmsg.to.add("1234567890@tmomail.net")
Txtmsg.from = new MailAddress("fromemail@comcast.com")
Txtmsg.subject = "low bat"
Txtmsg.body = "at blah time the phone battery was blah percent"
Dim SMTP as new SMTPclient("smtp.w14d.comcast.net")
SMTP.credentials = new net.networkingcredentials("username","password")
SMTP.send(txtmsg)
If you want, assuming this method works fine on phone, I'm willing to write it for you and publish it on my dev acct, but I won't spend time making it pretty, it'll be very basic and just do it's thing.
Unfortunately this isn't possible since apps can't send an email, text message, or make a phone call without user permission.
