How accurate is Accubattery?

[BlackZeppelin]

Hi all. Just for s...ts and giggles I downloaded this app, used my phone to 50%, (from 75%) and then recharged to 75% again.

I was shocked to see my battery health rated by Accubattery at 97%. This is an almost new phone and when I got the phone, my first 2 charges were to 100% using an older slow 10W charger. After that battery protection was turned on and most of the time I have charged to maximum 80% with the majority of times charging to mid 70's% and never dropping below 50%. Basically I have treated the phone with respect to charging like a baby.

Also, I remember a few years ago Samsung touting their new batteries as losing only 5% capacity in the 1st year.

So is this Accubattery correct or just a load of nonsense? Maybe others would like to test it for themselves. This is one of the extremely few features of iPhone that I wish Samsung had. An inbuilt battery health indicator.

Looking at mine, I'm wondering if it is any good or do I have to send my phone back...NOW.
This is from my one week old S22. Screenshot taken about five minutes ago, after the phone charged the entire night up to 100%.

A few months ago, I checked my two year old Pixel 4XL and it was showing 96% health and that was charged to 100% every night I owned it over those two-years (maybe a few here and there when camping that the phone was not charge...but you get the idea).

Looking at this, I too am wondering, is it worth the waste of time on the phone. Maybe I'll just to back to the philosophy I had with all previous phones, charge it like normal and let the chips fall (or the battery fail) as they (it) may.

But this app cannot be accurate.

Oh and the battery says it is at 99% which would be about right as for what is remaining. And I will say I have NO problem at all with the battery usage, in fact, it is more than great.

Lol, 69% on a brand new phone. You'll have no choice but to get the fold 4 as your battery life by then will be like 3 hrs SOT. Haha.

I've got it installed, and after a few days of charging it's rating my battery health at 92%, which I also thought was surprisingly low for a brand new phone. It does recognise the phone model as S22 Ultra and knows its design capacity, so wondering too if it's accurate. People in reviews seem to think so. My 3 year old S10+ was showing 86% battery health with the same app.

 

[Mooncatt]

No app is going to be 100% reliable on a phone. Proper capacity testing should be done with a dedicated tester and the battery disconnected from the device. That said, Accubattery is accurate enough for general use to get an estimate of health. It's also worth noting that batteries fresh out of the factory are going to have natural variances in their true capacity related to their rated capacity. It's not uncommon to find them a few percent lower than their rated capacity when new.

I have my own version of Accubattery... as I use my phones and notice the battery life seems to be getting shorter, with nothing changed on the phone and my typical usage, I realize my battery is starting to age Fortunately I've never had a battery get bad enough to cause me to quit using a phone. Usually by that time (2-3 years normally) I'm ready for something new

 

[fuzzylumpkin]

You can't really get an accurate measurement of battery health... that said, I've installed it on my year old S21 ultra and we'll see what it spits out in a couple of days.

Also, it's important to realise that a lower percentage than 100 isn't necessarily battery damage or degradation. All cells have different capacities, the rated capacity is an average. Everything here (except for RETG) is within normal variance.

 

[anon(40376)]

RETG deleted the app. Back to the philosophy of use it, charge it, like I did for all other phones. If a battery goes bad, and I need to replace it; I will. Not that hard; I have the tools, can get the sealant.

For me, the important thing is that I have power when I need to use the phone and so far, the battery on this phone is showing to be as good as any phone I have had. And I am using the phone at FULL power. Only thing I have disabled is 5G, since I don't have it where I live and when I travel don't need it.

You may want to give the app a little more time -- it might need more than a couple of charge cycles to give an accurate estimate. If it still reads really low after maybe 10-20 cycles, then I would agree that the app is probably not correct. In that case, I would also send feedback to the developer.

 

[anon(40376)]

I really do not need the app. I installed it on my 4XL last year more out of curiosity. And I really have a hard time believing a two-year old Pixel 4XL has a battery still at 96%. The battery still worked for me, lasted easily through a day but 96% after two-years?

Maybe after a year I'll re-install. Not sure I have opened the app since the day it was installed until the AM when I read this post and checked it. Using the phone daily and keeping an eye on the level when I put it back on the charger will tell me all I really need to know.

That's because you have an s22 and you put the design capacity at 5,000 which it's not...I believe the s22 only has a 3500

I used to obsess over battery health using Accubattery...until I realized 2 things:

-This wasn't going to be my forever phone, and chances were that in a year, any phone I had would become my side-side-side phone.

-constantly charging to a specific amount is extremely restrictive for a device that's supposed to give you more freedom

If you think about it, there technically shouldn't be a time that your phone dies, since you can charge at your desk, charge in your car, and charge at home. Foresight is probably the best tool to use, and before anyone gets upset, I'm not calling anyone dumb or shortsighted. I'm just saying that if I know after work that I'll be going out to dinner, I should probably charge my phone at my desk to a comfortable amount. Likewise, if I'm driving, I should probably plug in/buy a charger if I have long commutes.

Long story short, battery life is probably less important than charging speed, and if you charge when you need it, by the time it becomes terrible, you're probably on to your next phone anyway.

Typo, forgot the "U" it was 3:02 AM. I have a S22 Ultra.

Gotcha? Regardless it's only been 2 charge sessions. it'll change as you charge your phone.. my reads 97% which is pretty much how all my new phones read using that app

I couldn't agree more with this.

Paid user of Accubattery here and I've also been saying for a while, the app is terrible. It makes you anxious about charging and gave me information that was questionable and not particularly useful. You spend a lot of money on the phone and Accubattery just saps the enjoyment out of it by making you always worry about your battery when...... you're probably going to trade it in WELL BEFORE you will ever see a noticeable degradation of the battery itself. I never use it anymore.

To be honest I've always stayed away from battery apps.

They can be glitchy and by the very nature of them continously working in the background they have the capability of using a decent amount of battery !

Well that's my 2 cents anyway.

 

[fuzzylumpkin]

Well, after 1 charge session my S21 ultra is apparently at 96% health. Nice if it's true after 14 months of not babying the battery.

Accurate or not though, I'm not sure the information is useful in any way.

Yeah, to me it's like all those "cleaner" apps. They don't do much but cause stress and use battery in the background.
