Z1558178530959, Jun 26, 2019 : Hi , I have been using my OP 7 pro for the past one month , it is really an Exhilarating experience yet this issue is persistent. WhatsApp is draining my battery more than any other application (I played PUBG for like 30 mins it was like around 10%). I constantly use WhatsApp , for 2 hours of use of WhatsApp it saps up my battery upto 30%. It is the most battery consuming app , when I check on battery usage. Please Re-affirm why is this happening?. Are there any possible solutions for this .
