Has anyone else noticed significant battery drain from WhatsApp usage recently?
Here's the deal. I'm running 8.1 on a Lumia Icon and I've not had a lot of the issues that others have experienced with WhatsApp after installing 8.1. I let it run in the background so that I get notifications and because of that I constantly "X" out of the app when it's not in use.
Today at 3:30 my time my phone was at 60%. I had just talked on WhatsApp, (not sure if I closed it but that shouldn't matter as I've forgotten to close it before) set my phone down and started doing other things around the house. I came back to it at about 5:30 my time and the phone was completely dead. I looked up battery usage under settings and found that it was WhatsApp that was using all the juice. I set my phone on the charger at 5:30 and it is now almost 10:15 my time and it's only now getting to 85%. Usually my phone will go from no charge to a full charge in less than 3 hours. I've not had this happen once since updating to 8.1 and find it odd that it started up all the sudden this afternoon.
Anyway, WhatsApp is still sucking up the juice, even as I'm charging, so I set it to not run in the background hoping that helps. I'll see what happens but was curious if anyone else was running 8.1 fine with WhatsApp and has recently started having problems.
