Oh god, here we go again.
My nexus 6p had gotten a little bit worse over time about how long it lasts for me without charging. But the Oreo update recently was a huge battery saver. I could last throughout the day at work with heavy usage for work without even getting to 30% by the time I got home.
But today, for some reason, the battery got drained big time. I was down from fully charged at 7:30am when I left home, to 37% left by 11:30am. The battery page says 13% was used by Whatsapp. I can’t not use Whatsapp, that’s the app I use most of the time to collect paperwork and consolidate the data from my customers. I restarted the phone and put it battery saver mode. Hopefully it can last me another 5 hours at work. And hopefully this is not a sign of things to come. This is always the reason I’m forced into getting a new phone every 2 years. This and forced reboots, which luckily haven’t started yet.
EDIT: Restarting the phone and putting it into power save stopped the bleeding, so to speak. During the last 90 minutes, the phone has used almost no juice.
