My mom charges her Galaxy S25+ to 100% daily; our batteries tell very different stories
As an Android Police author, I've noticed a stark contrast in battery health between my mom's and my own Galaxy S25+ devices, despite using the same phone. This sparked my curiosity about the impact of charging habits on battery longevity. I've always been cautious about my charging practices, keeping my phone's maximum charge at 80% and topping it up when it reaches 20%. My mom, on the other hand, charges her phone to 100% daily, a common practice that I've heard others advocate for. But the results of our battery health tests surprised me.
I ran diagnostic checks using the Samsung Members app and third-party apps like Battery Guru and AccuBattery. The findings revealed a noticeable difference in battery capacity. After four days, my battery capacity was estimated at 4,406mAh, while my mom's was 4,505mAh. This discrepancy is attributed to my 80% maximum charge capacity, which aligns with the theory that exposing the battery to a higher voltage during the final charging stage can impact its long-term health. Despite this, both batteries are still in good condition, but I'm eager to see if my more conservative approach pays off over time.
Another factor influencing battery health is the charger. I've learned the hard way that using cheap, third-party chargers can lead to overheating. My mom's phone, charged with the same charger, shows no signs of overheating, suggesting that the choice of charger matters. This experience has made me more mindful of the importance of using chargers that match the phone's wattage to ensure optimal battery performance and longevity.
In conclusion, while my mom's daily 100% charging routine may be a common practice, my more conservative approach has resulted in a noticeable difference in battery health. As I continue to monitor the long-term effects of my charging habits, I'm reminded of the importance of understanding the nuances of smartphone battery care and the impact of individual choices on device longevity.
