My mom and I’ve the identical cellphone. We ordered ours on the identical time from our provider. We personal a Samsung Galaxy S25+.
Whereas we each love utilizing our Samsung telephones, our routines and settings are completely different. A kind of habits is charging, in addition to battery-saving.
I am adamant about charging my cellphone irregularly and conserving the utmost cost at 80%, whereas she steadily retains hers at 100%.
It has been a 12 months since we purchased our telephones, so I needed to take a snapshot of our battery well being and examine our practices.
Our approaches for sustaining cellphone battery well being
We’re comparable however nonetheless deviate
I normally maintain my cellphone’s cost between 20% and 80% once I can, although it has dipped to fifteen% or decrease a couple of instances.
My mother prices her system extra steadily; she likes to high it off earlier than work and prices it in a single day, whereas I by no means do.
Our utilization is completely different, however not by a lot. We each have a tendency to look at movies, take heed to music, use varied apps, and use it for texting.
Neither of us really video games on our Galaxy S25+. I take advantage of it extra for Galaxy AI options than she does, comparatively talking.
All in all, we’re each thought-about moderate-to-heavy customers.
One other distinction is how we use our battery-saving choices. I take advantage of a customized battery-saving mode to take care of my cellphone’s battery well being.
On the identical time, my mother turns it on manually when the battery reaches a sure stage, normally when it begins falling under 20%.
I’ve additionally custom-made my display timeouts and turned off adaptive brightness, opting to regulate it manually as an alternative. She retains the default display timeout and makes use of adaptive brightness.
These choices affect how usually we might have to cost your gadgets. I give attention to maximizing daily battery life, whereas she focuses on normalized patterns.
However the greatest distinction is altering the maximum charging capacity, since that is imagined to affect the long-term well being of your cellphone’s battery.
As a tool prices and discharges, its capacity diminishes over time, primarily because of chemical degradation within the cellphone’s lithium-ion battery.
Warmth is a byproduct of charging and discharging. Typically, over the last 10% of charging, a lithium-ion battery can generate vital warmth because of inner resistance.
Warmth is what we concern, as it will possibly injury inner parts, such because the battery.
To fight this, I grew to become diligent in my charging practices.
I maintain my most at 80%, and I high off my system when it will get close to 20%. Sometimes, my cellphone’s cost is within the 50% to 60% vary.
Although I do know this may not have a direct impression on my battery well being for a couple of years, I made a decision to run some exams and examine them to my mom’s, who does not imagine in these practices.
The primary take a look at concerned doing a normal diagnostic cellphone test. I ran the Samsung Members app’s diagnostics take a look at first.
I used that take a look at to make sure that there was no main fault with our batteries.
Secondly, I checked our gadgets at 78% to 79% and took a fast snapshot of the estimated time from the settings menu.
I take advantage of darkish mode; she makes use of mild.
After I downloaded two apps which were pretty first rate at checking my device’s battery health, these apps are Battery Guru and AccuBattery.
The outcomes weren’t stunning apart from one factor
My 20% most cost capability loss is noticeable
On the fourth day of the take a look at, the battery capability estimate for my mom’s cellphone, measured by AccuBattery within the charging part, was 4,505.0mAh.
Mine was at 4,406mAh. I assume that, since it is a stat measured whereas charging, my 80% cap influences the estimated battery capability (so I ought to have a smaller quantity by default). That is true. I cross-checked it.
Comparatively, our numbers aren’t far off on condition that I’m solely charging as much as 80%, whereas my mom diligently retains hers at 100%.
The Samsung Galaxy S25+ has a design capability of 4,755mAh (Samsung formally charges it at 4,900mAh).
The subsequent worth I checked was the Well being part. I set my most charging capability to 100% for this take a look at so I may extra precisely mirror the estimated well being.
Mine was set to 95%, and so was my mom’s.
I additionally determined to test what Battery Guru estimated.
Battery Guru is my go-to app as a result of it helps me manage wakelocks that may typically intervene with my system’s display time, so I’ve had it on my cellphone since I put in it a 12 months in the past.
I’m extra inclined to belief Battery Guru’s estimated values for the reason that extra charging/discharging cycles it detects, the extra information it will possibly measure.
Sadly, this would not maintain true for my mom’s cellphone, since I solely had 4 days to run these exams and needed to set up each apps on the primary day.
For my mom’s cellphone, the standing is “studying” (technically, my standing modified to studying for the 100% capability take a look at), regardless that it has been 4 days since I performed the take a look at — which doubtless means she simply is not charging or discharging it steadily sufficient.
I semi-expected this as a result of she takes care of her cellphone, and whereas we’re in an analogous class as moderate-to-heavy customers, I lean extra towards the heavier facet than she does due to my job.
Based mostly on the information, battery well being was measured at 98%, and her capability was evaluated at 4,671/4,755mAh, which is once more fairly wholesome.
For me, it was at 94%, measured at 4,460/4,755mAh. That is nonetheless wholesome given how exhausting I push my cellphone.
All in all, our batteries are nonetheless in pristine situation after a 12 months of use. Nevertheless, I’ve but to see if my 80% most has paid off.
In idea, it ought to, since I’m not exposing the battery to the next voltage throughout the last stage of its charging cycle.
Although I anticipate to note a slowdown with age (much less put on and tear) after a couple of years of use.
The speed at which it does must be much less — however the query turns into: How a lot?
Thus far, my mom’s cellphone’s battery appears to be in higher situation, although this may increasingly rely upon our utilization patterns and the accuracy of those exams — these are nonetheless third-party apps, not official Samsung instruments.
However I used to be stunned to see mine being worse by a noticeable quantity.
Your alternative of charger issues too
Whereas these exams have been finished in the identical family, I used to be ready to make use of the identical charger for each.
I keep away from third-party, low cost chargers that don’t match my phone’s wattage.
I’ve been punished through the use of cheap cables which have truly heated my cellphone, no matter my settings.
Should you discover your system heating up whereas charging, it could be because of your charger, relatively than the settings you are utilizing.
