Do You Charge Your Phone to 100%? My Mom and I Compared Our Galaxy S25+ Batteries (2026)

In a world where smartphones have become an integral part of our daily lives, the way we treat and maintain our devices can reveal a lot about our personalities and habits. This story is a fascinating glimpse into the different approaches two individuals, a mother and her child, take when it comes to their Samsung Galaxy S25+ smartphones.

The Battery Battle

While both individuals share the same phone model, their charging and battery-saving practices couldn't be more distinct. I, the author, am an advocate for irregular charging and keeping the maximum charge at a modest 80%, a practice I believe will extend the life of my phone's battery. On the other hand, my mother, a fellow Samsung user, prefers a steady 100% charge, topping off her device before work and overnight.

Usage Patterns

Despite our differing charging habits, our usage patterns are surprisingly similar. We both engage in activities like watching videos, listening to music, and using various apps, with a moderate-to-heavy usage profile. The only notable difference is our approach to gaming; I tend to utilize the Galaxy AI features more frequently, while my mother keeps her gaming to a minimum.

Battery-Saving Strategies

When it comes to battery-saving options, we each have our unique strategies. I've customized my phone to maximize daily battery life, using a custom battery-saving mode and adjusting screen timeouts manually. My mother, however, takes a more reactive approach, turning on battery-saving mode manually when the battery reaches a certain level.

The Great Charging Debate

The biggest point of divergence in our practices is the maximum charging capacity. I've diligently kept my maximum at 80%, believing it will preserve the battery's health over time. My mother, on the other hand, charges her phone to 100%, a practice that goes against the grain of my battery-preserving philosophy.

Testing the Theories

Intrigued by the potential impact of our differing practices, I decided to run some tests. Using diagnostic tools and third-party apps like Battery Guru and AccuBattery, I compared the battery health of our devices. The results were intriguing, with my mother's phone showing slightly better battery health, despite her 100% charging practice.

The Charger Conundrum

One factor that might have influenced the results is the choice of charger. I'm a firm believer in using chargers that match the phone's wattage, avoiding cheap, third-party alternatives that can heat up the phone. My mother, however, may have been using a different charger, which could have impacted the battery's performance.

Final Thoughts

This experiment has been an eye-opener, highlighting the impact of our charging habits on battery health. While my mother's phone seems to be in slightly better condition, it's hard to say whether this is due to her charging practices or other factors. It's a reminder that while we can take steps to preserve our devices, there are many variables at play. Personally, I think I'll stick to my 80% charging strategy, but with a bit more openness to the idea that sometimes, the 'right' way might not always be the best way.
