Hi. My neighbor suggested I use the accubattery app for my Samsung cell phone. I started using it for the original that was measured at 97% after the first capacity test. I took it down to 7%. Charged it to 100% as they suggest.
After 3 and 1/2 years the capacity was 77% according to my accubattery app. It struggled tremendously when it got to 35-40% when I was out in the cold it just plummeted.
I just got a new battery for it yesterday. The app says to discharge to at least 15% and then do a full charge. After the initial test, This time it has my battery at 93% capacity. I also discharged it to 7%. And gave it a full charge to 100%.
I know there’s variations but already I’m 7% lower than 100% and it is brand new. Manufactured September 19th 2024.
The typical capacity of this battery is 4500 mah. The rated capacity is 4370 mAh. My capacity is 4078mAh which is 93% of that 4370 mah. Is that a coincidence that the amount charged is the same amount that’s the rated capacity of the battery? How would you get it to 100% unless you drain the battery to zero? I’m guessing this is not how it’s done and my 93% is just a coincidence.
I think I have to do several tests to get an average. I think it says it will measure five capacity tests and then get that average so maybe I have to wait until then till I get a better number. Any insight on this? Thanks
Certainly seems like an OEM battery. I got it from You Break I Fix. I requested to look at the battery and I took a picture of it. This one’s made in China my original one was made in vietnam.
The battery level on the screen is the percentage you have at the moment. The capacity of the entire battery, the battery health is supposedly measured by this app. That is the difference.
Equate it to an opus or another battery analyzer/ capacity tester.
These apps can’t access raw BMS readings and are therefore not particularly accurate. Useful as a rough information, but not more.
Also, unless you buy directly from the manufacturer spare parts shop or known good sources like ifixit, I would always assume that all spare parts sold are third party fakes, no matter if sold as “original” or not.
You never know if this number is 1000% acuret… !? Maybe the manufactur has rounding the numbers a little bit, and maybe app measurements are a little bit off ± “plus or minus”, so a ± 97% capacity or a - 3% or a - 7% difference is pretty dead good - pretty dead acuret !
You’re right, they aren’t the most accurate. Not sure what the difference is between iFixit and Ubreakifix? I trust they get genuine Samsung batteries. The last one did very well. For as much as I use the phone.
You’re right. It’s an app and it’s not 100% accurate. I think you misunderstood something I wrote. The other battery when it was brand new show 97% capacity. No complaints.
This one brand new shows 93% and actually dropped to 92% after my second capacity test.
Same battery. Same app different results. Even if it’s halfway accurate starting off at 92% could make it difference down the road. I got a one-year warranty so I’ll keep monitoring it.
That the numbers aren’t that much off… we all know the reasons… (different measurements, different equipment, different temperatures… everything is different…) and you might be a little bit off, and it doesn’t matter at all… is just a battery - a chemistry with some very fine natural metals and natural elements inside… and they are quite “unstable” to work with them… so is quite difficult to make them… and quite difficult to make 1000% correct - acuret… !
So at the end of the day… out of nothing… we have a very good product… that is and works pretty damn good and acuret and correct for - from what it is… !
So i think… doesn’t need to spend more time about - on it… !
I think you can get my point of view… !
And understand what im trying to say… !
To me 5% capacity difference right off the bat may be a factor down the road. Just like my . I like the most output. I want my batteries to have the most capacity.
These apps are only estimating things. They require multiple charge cycles to get better estimates. Measuring while charging is not the best way to measure any batteries capacity. There are a lot of variables at play. If you’re using a different charger or cable then you were x number of years ago you could get different results. Phone temperature, whether or not the screen is on, cell tower signal, Wi-Fi signal, more apps running in the background, plus other variables are all things to consider. The reason these matter is because they could be using slightly more power while you are charging which means that it takes longer and more power to charge the battery back to full. The app doesn’t know that. If you want the battery to last a long time don’t charge it past 85 or 90%.
I know there’s variables. I know there can be differences. I know it’s not rocket science. This pertains to both batteries and test.
Wi-Fi was used. The screen was off and no apps were in the background. they were charged and discharged the exact same way under the same circumstances… . Same battery capacity and manufacturer. Same cable. Started charging at 7%. Ended it at 100%.
I compared Apples to Apples that’s all I could do . Being that I did everything the same I would hope the results would be better for the new battery… Maybe I’m alone that’s okay. To me getting a battery that’s 92% capacity compared to one that was 97% is a difference. Especially when they’re brand new. Time will tell if it matters in the end as far as degradation.
All in all I have a one-year warranty if I notice it degrading quicker than it should I just get a new one for free. I’ve done it before and I’ll do it again.
This is not how I would treat my battery. This is just to get the capacity test. That is what they recommend.
I charge to 80% and discharge to 30% been doing that for years. The 80% is programmed with a timer for this ACU battery. More like an alarm.
That doesn’t apply to me. My desktop is history. The tablet I have is slow. It was a free gift. I use this phone more than most because of the situation I just told you.
I charged my old phone at least twice a day and as the battery aged three times a day. This is still a new battery and a good battery. Slightly less capacity than I hoped. Probably charge it one to Two times a day depending on how much I use it.
Charging and discharging by the 80% /30% suggestion.
I never said I did not know the capacity. The App tells you and constantly monitors it.
Primary reason I started this thread was because of the 5% difference in capacities of brand new batteries.
I know the health of the batteries. This app is pretty decent at letting me know. The same way that an opus keeps me up to date with battery degradation. Just a different method.
. I like the most output. I want my batteries to have the most capacity.
