I have had the one plus 7 pro 5g since the 30th may and the battery had been excellent leaving me with about 25% at bedtime. However over the last few days it has been draining really fast to the point that as I type this at 6pm with very little use during the day its currently at 22%. Has anyone else noticed this? I looked at apps that had been updated recently but they don't seem to be culprits. The biggest iss of the battery is Google play services. Is this normal?
