Which phone you’re using and what are your reviews about its battery life ?
Oppo, Vvo and some samsung series are going good in battery life’s factor.
Is it Vivo ? You’re talking about.
I’m currently using a refurbished iPhone 13 Pro Max, and I must say, the battery life is amazing. It easily gets me through the day with plenty of power to spare.
