Last Month my phone went to service center because the bottom speaker died, They Replaced the whole motherboard and finish it last week. After a week of normal usage, i found that the battery life isn't as good as it was before service. Idling 10 Minutes drain the battery by 3% and when i tried 2 "battery apps" from playstore, it shows the battery is at 8 Volt. Is that normal ? Tyia
