Priming my battery - what is the max capacity in mV? - Galaxy S II Q&A, Help & Troubleshooting

Hi,
Last night I purchased my S2 and am in the process of priming my battery. Could anyone tell me what is the standard (in the box) battery capacity that is achieved after the going through a few cycles of charge/discharge I should expect?
Coming from a HTC Desire HD, I am so far impressed with the S2, way better in every respect.
Thanks for your input

Didn't know the battery capacity could be variable in a battery... are you talking about battery duration?

Talking about the value reported in apps, the like of Quick System Info PRO, where one can see the state of the battery. For example, when my DHD arrived, batter was only at 3500mV. After a week of "training", a.k.a. priming of the battery, I reached full capacity of 4204mV when charged at 100%.
I am simply trying to establish where my battery is at today + how many cycles of charge and discharge it needs to span full capacity. Talking about this for example
Breaking In New Batteries - New batteries come in a discharged condition and must be fully charged before use. It is recommended that you fully charge and discharge your new battery two to four times to allow it to reach its maximum rated capacity.

[Q] How Many Charge Cycles Can I Expect?

Since the battery on my newly acquired Razr Maxx can't be removed and replaced, how long will this phone last me? Charge cycles?
Is it OK to drain the battery all the way down (charge every other day) or will that shorten battery life?

No Official number but in general batteries typically are spec'd to last 300 cycles before there charge is 50% capacity of what it was new, So I always make it a thing to go aslong as I can hold out between charges, just don't try powering it on if it shuts itself off from low battery, that is a fast way to kill a battery, also there are tutorials on how to crack open the case and replace the battery if you end up needing to, but by that point you will probably have moved on to some quad core phone that will be all the rage in 2 years.
With li-on batteries, its best for the battery if you charge around the 40-30% mark. There is a chart out there somewhere, but I don't have it handy. You also don't have to worry about a memory any more
Yes... Only Ni-Cd and Ni-MH batteries have memory problem and Li+ doesn't have those issues...
Top-up the battery whenever possible + need arises... This also reduces battery getting hot, comparing charging from say 10% to 100% at a single stretch... This is useful as Razr/MAXX has non-removable battery....
PLEASE DON'T LET YOUR BATTERY TO GET DRY OR 0% LEVEL and PLEASE DON'T CONNECT TO MAINS FOR LONGER TIME after battery becomes 100% charged... Only these two must be avoided...

Battery calibration.

Hi, I was asking myself if it was possible to copy batterystats.bin from a calibrated x10i to have our own x10i calibrated.
I explain : I see that file like a file with values that have the percentage of the battery with the duration and stuff like that, so copying it to have the right values.
Can work or not ? influenced by kernel or rom ? What do you think ?
Li-Ion batteries just need a good charge for approx 8-12hrs when new and first installed and having this process repeated for at least 4-5 charges.
The phone doesn't allow the battery to over change and cuts out and then starts changing again once the charge drops to a chargeable threshold.
This allows the battery to achieve it's maximum charge.
Li-Ion batteries should never be drained or allowed to run flat and should be charged regularly.
If you completely discharge a lithium-ion battery, it is ruined.
Li-Ion battery life is between 2-3 years.
I would let the battery sort itself out as all the battery status is based on the battery itself.
If the battery is old and on it's last legs, it'll have less charge than a newer battery.
P.S. If you plan to keep and use the XPERIA X10i for some time, it's well worth buying a Mugen Power 1800mAh battery.

Battery Charge Limit - Preserve your battery.

Hey, just wanted to let you guys(and gals) know that this app works perfectly on our axons: Battery Charge Limit.
https://forum.xda-developers.com/android/apps-games/root-battery-charge-limit-t3557002
It does exactly as the name suggests, stops the battery from charging beyond a certain percentage, thus for example if you set a limit of 80%, your battery will preserve its health for around 1500 cycles instead of 500 cycles of charging to 100% before degrading by ~20% of its total capacity.
Enjoy the app guys, tested on B19, stock kernel, rooted.
So the way to have 1500 cycles is to only use 70% of battery at best. Because going under 10% is not exactly good for the battery either. I don't want to have an even worse battery life, so I think I'll pass, thanks though!

Don't go under 90ish as you will stop charging whilst quick charging and will damage the battery even more than if you didn't use the mod so just be carefull

Dont let them fool you, you dont need this app. The charging controller of your phone actually already has its safety margin built in. Same on the low end. This means you can not charge your phone to its physical maximum anyway, it will show 100% whipe the physical charge in fact is ~95% and will shutdown showing 0% while physically there is still about 10% of power left. So your battery is safe from this kind of damage anyway.
If you want to extend your batterys lifetime for real, try to charge it as often as you can, keep the charge as high as possible. Flat charging is the magic word. This is what your charging controller does when your phone is connected to ps for longer when it shows 100%, it in fact lets it deplate 2% without showing and then charges it back, thats called trickle charging and is the best treatment practice for our bateries.

Samdung pretty much confirmed they do this (or better) in the S8 and later (and possibly the S7). But has any other company confirmed they have battery longevity tactics built in?
Personally I use AccuBattery since I've had it for a long time as a charge alarm/monitoring tool. I use a 1 amp charger instead of the 3 amp charger that comes with it and charge my phone at low amps and voltage which prevents the battery from heating up. So low charge, low heat. I don't want a degraded battery in a year because I don't know when I'm replacing this thing.

AccuBattery is no good for giving an accurate estimate of the actual capacity when you're charging at low %s. For first 50% it'll calculate something like 3500mAH+, for the last 50% it'll estimate 2000 or lower. If I had to give you a rough estimate of what I actually think it's at, it's roughly 2900-3000mAH. When I first got it, I estimate it was around 3100-3200 a year ago. I HATE that phones no longer have replaceable batteries. That's half the reason I wanted an LG V20, I could just murder the battery and just pop in a new one every year. Sadly the V30 is sealed, following the BS trend of planned obsolescence. Thanks Apple.
Oh and I almost forgot, I typically charge my phone from 20% to 50% after it drops 30%. Then sometimes once more if I use it some more. On average I charge about 50% worth a day without going over 50%. Even with such light battery usage, keeping the battery 30C or lower 99% of time, and keeping the voltage below 4.1 again 99%, it's still degraded at least roughly 200mAH in a year. Rarely when I know I'll need longer battery life I charge it to 80%. It's a cheap quality battery. ZTE cut corners. This was my first, and unless I have no other reasonable options, it'll likely be my last ZTE phone.

can you TL;DR this for me?
-So i better keep charge between 20% and 80% yes?
my old sony phone form 2011 still works nicely, as it had Quality battery (over 2000 cycles already) yeah does not last long 2/3 but still. useable.
And i agree, replaceable batteries is must have function, My old S3 and S4 worked for "ever" because of that, every year new battery and another year of usage! (s3 still going strong since 2012 !!! )

Apple has been using enclosed batteries for like 10 years or so.
You can do better than the app by setting a lower maximum voltage on the Axon 7 instead. I posted about the discovery awhile back on that thread https://forum.xda-developers.com/showpost.php?p=74746734&postcount=1353

Essentially, yes, that's what I keep hearing whenever I dig for information. If any of the stats of AccuBattery are accurate at all then it also supports that going over 80% causes multiple times the degradation that charging up to just 80% would. These days I try not to go over 70% based on app estimates of degradation. These days I need more than the 50% I was previously charging to.

Battery capacity

Has anyone checked the ROG phone "Battery health" on AccuBattery Pro? Mine is showing Estimated Capacity as 3,548 mAh, Design Capacity 4,000 mAh. I completely discharged then charged to 100% as calibration. Brand new phone.
Mine is showing 3,531mAh after around a week of usage.
Someone should report this on the Asus forums
mine also show 3500mah after 2.5 weeks of use
I have posted this issue on ASUS's Forum
https://www.asus.com/zentalk/thread-249329-1-1.html
Please feel free to add your battery capacity screenshots on their forum so we have a reference for the future
Mine's at 3462 after a little over a month. With a health of 87%
OK, then. We shouldn't be concerned. The proper way to measure battery is more complicated than what AccuBattery does (the proper way involves measuring battery discharge at a controlled rate). Since many of us are getting similar readings on AccuBattery, it's probably that AccuBattery's method isn't accurate.

Same here: 3536 mAh 88% health with Accubattery first charge out of the box after discharging to 15% following first power up.
Either Accubattery has a problem with our phone, or Asus is ripping us off.
If the batteries were bad, we'd all have different readings.
I am guessing the AI charging might affect the measurement from AccuBattery. However I also don't think the battery capacity is full 4000 mAh. My last phone from Motorola has a 3000 mAh battery on the spec chart, but the battery itself prints 2810 / 3000 mAh (min/typ). From the ROG phone tear down videos, this battery isn't marked though.
From the asus zen forum the only solution the person provided was to bring the device to a service center to get it tested
I maybe wrong however with batteries these days it only ever uses a percentage so that there is redundancy for failure and to preserve the battery life.

Samsung does that. Note 9 is 4000mah but Accubattery says 3800mah on new phones. Every one of them.
Power reserve to not kill the battery early.
Anyway, 3500 mAh seems like one heck of a left over reserve.
Our batteries should last 5 years at least
Same "problem" here, but maybe it is because program has small amount of gathered data about battery usage. I did full discharge and full recharge yesterday, and goz about 3567mAh, but ill try to calibrate battery and use measuring app for longer time to get more accurate results.
Ps: I am using only slow charger to avoid overheating to eliminate battery damaging when recharging
I have not checked my ROG Phone in any 3rd party apps as I have not had a reason to question the 4,000 MAH
It is not a problem, lithium ion battery deteriorate faster if kept fully charge all the time or when discharged to low. Since most people have the bad habit to plug their phone all the time and keep them full for a prolonged period of time, oem have to be creative to fight this. Some will show your battery is charged at 100% while in reality its only charged at 90% .That is what your program most likely reading.
lithium ion should only be charged at 100% before you leave the house, i tend to keep mine between 50 and 90 usually . With quick charge there is no reason to keep a phone plug overnight, 10-20 min before leaving the house is plenty.
I have turned on AI for battery charging and as soon as my Battery reaches 100 it stops charging which is good enough for me to have faith in the charging technology in the phone and battery capacity.
I do leave mine plugged in over night however with the right equipment to check its hard to get a good understanding of whats happening. Theres inbuilt battery health tools so i would always advise using these and going through the features of this over 3rd party jank applications and trust them. Its the only tools Asus are going to support in any diagnostic troubleshooting.
Hi guys, I am returning after some time of usage and charging. After some charging cycles I have to admit my battery capacity is "increasing" - well better say, it is getting used to be charged properly. Now I passed 7 full charging cycles, but after 3rd one every next charge had more mA. I started at 3479mAh with full battery, now I ended with 3711mAh - hope it gets even better (I'll be glad for at least 3800, but who knows?). Everytime I tried to charge only when I was below 3%.
I have to say I am using slow charger with 5V and 400mA current. Battery checker from mobile manager was not detecting any issue with this way of charging nor AccuBattery Pro. I also know, that batteries shall be charged only about 80% of its capacity, but I am still sceptical about that rest 20% so I am charging to max everytime.
Hope I helped...
...another time passed and I am back with another results. After a lot chrging cycles I am stuck at between 3500-3700mAh of total capacity. I was searching around whole internet and found out, that phone manufacturers are "decreasing" battery capacity with SW at 90% of total capacity to prolong battery life and avoid battery wear, because everytime you charge the phone, you think you are charging to 100%, but in real you are charging to 90% only - rest of 10% is "hidden" to save your battery life - due to my calculations and testing it might be true. Anybody else had something different, so we can compare it?

Expected max voltage, capacity, of replacement battery

I seem to get reduced maximum capacity even after fresh battery replacements.
Most recently I purchased a new replacement battery from iFixit. With this new battery, just like the previous one I bought a year ago from Amazon, my phone charges the battery to a what seems to be around 80% of its capacity. The maximum voltage when reported charge reaches 100%, as reported by the phone, is 4.225V (according to multiple apps). Capacity as measured by AccuBattery is around 80% or 2800 mAh.
I've tried many things, such as the battery calibration multiple times (both method 1 with USSC codes, and something like method 3 which iFixit recommends), without any major apparent improvement.
Things I am wondering:
Should the battery voltage when at 100% charge be closer to its rated 4.4V than the maximum 4.225V my phone is seemingly able to reach?
Can I expect to see improvements if I keep going through a few cycles of battery calibration and full charge/discharge?
Is there any other way to reset the phone's perception of battery capacity or wear than the battery calibration options?
I found another thread with a similar description to my own experience here.
In 3 years I have replaced battery 4 times, now something odd is happening.
I'll make a note to dig out my old USB tester and check how much total juice is pushed into the phone with a charge from <5% to 100%.
More details of my battery history for more background and for anyone interested:
I used the original battery from purchase in late 2018. My charge pattern for the first 2 years was typically charging to 100% every night, and topping up during the day as necessary.
During winter 2020 it performed terrible in the cold (not any extreme cold, only around 0 C), and once drained from around 80% to 35% in less than an hour of continuous use (photos, filming) and then died. After this I changed my charging pattern to where I was keeping the phone from exceeding the 70-40% range as much as possible.
In December 2021 I purchased a replacement battery from Amazon (supposedly original). The original battery was reportedly at 80% capacity says AccuBattery. How reliable that measurement is I don't know (it is all data reported by the phone itself as far as I understand), but the capacity had gradually decreased over the three years of use. I can't recall the voltage readings though, and I don't seem to have any screenshots saved from that view.
The new battery didn't ever seem to be able to exceed the capacity of the 3-year-old original battery (which had gone through over 1,100 charge/discharge cycles as tracked by AccuBattery) that it replaced. It's more stable (especially in cold conditions) but has not brought any increase in usage time compared with the battery it replaced.
With the now 10-months-old Amazon battery, having gone through less than 400 charge/discharge cycles according to AccuBattery (which is relative to the max capacity of approximately 2800 mAh or 80%), my phone in the past month gave me the pop-up notice indicating a poor battery. The capacity reported hasn't changed much over these 10 months of use.
Update with USB tester and comparison with a Samsung Galaxy S5 Neo.
TL;DR: 2800 mWh is the new 3500 mWh
First, S5 Neo.
I have an old S5 Neo, last of its era of Samsung phones with easily replaceable battery. I purchased a new battery for this phone from iFixit in the same order as the S9+ replacement battery.
S5 Neo's battery is rated at 4.4 V (3.85 V nominal) with a 2800 mAh capacity, or 10780 mWh. Depleting the battery and making sure the phone would no longer switch on with the power button, I charged it from 0% to 100%.
After slowly charging for 3 hours at just below 4.8 V and 750 mA for most of the time, the USB tester showed 10780 mWh, and the phone showed 92% charge. At the 3h 30min mark, shortly after reaching 100% (I didn't catch it perfectly), USB tester showed current had dropped to 350 mA and total charge delivered was just over 12000 mWh. After another 10-15 minutes the charge current dropped to zero and total power delivered showed 12326 mWh.
The S5 Neo phone, using the app GSam Battery Monitor while the phone is otherwise idle, it shows an internal battery voltage reading of 4.38 V when fully charged, still plugged in and trickle charging. Once it's saturated (charging icon disappears) the voltage drops to 4.33 V.
Going by the USB tester results and progress shown by the phone, and with the assumption that the battery is able to be charged to its full rated capacity with this old phone, the battery charged to capacity with an efficiency between 87.5% and 92%.
I also captured a few mid-way readings. Here is the complete list of my captured readings including comparison to rated capacity assuming perfect efficiency (with extrapolated total charge for levels below 100%):
100% (charging current at 0.0 A)12326 mWh~114% of rated capacity100% (still charging)12062 mWh~112% of rated capacity92%10780 mWh11717, ~109% of rated capacity81%9291 mWh11470, ~106% of rated capacity62%6440 mWh10387, ~96% of rated capacity33%3160 mWh9575, ~89% of rated capacity19%1868 mWh9831, ~91% of rated capacity
The extrapolated charge to reach max rated capacity is increasing as charge level goes up, which I think is kind of expected. Conversely, the efficiency is a little lower than I would have expected. Still, the total power required to reach 100% exceeds the rated capacity by a fair margin. Better still, the phone itself reports a battery voltage near the battery's rated 4.4 V.
Second, S9+.
As mentioned in the original post, the internal battery voltage max reading is 4.22 V, and the capacity seems to not reach the expected level. Checking the Battery status option of Diagnostics in the Samsung Members app to check the battery, it shows it is in "weak" condition. Resetting all the battery related readings using USSC codes (see battery calibration) doesn't seem to change anything.
The battery is rated at 4.4 V (3.85 V nominal) with a 3500 mA capacity, or 13475 mWh. With fast charging disabled, and after draining the phone until it powered off and would no longer power back on, I started charging via the USB tester. I'm using a Samsung travel charger this time, which delivers a little more current than when I charged the S5 Neo.
Charging starts out at just below 5 V and 1.5 A. Current quickly drops to 1.172 A, and somewhere between 33% and 50% it drops to 1.072 A. This current is stable until beyond 81% and then starts to gradually decrease throughput the rest of the charging cycle. (Actual charging current is slightly lower with screen off vs screen showing current charge level.) This I believe is indicative of the battery capacity (or perhaps rather the phone's perception or expectation of the battery capacity) is below its typical levels. It could also be a difference in how the S9+ charges compared with the S5 Neo, or perhaps less likely a difference between the chargers used, I can't really know for sure with only my two samples. In comparison, the S5 Neo kept charging at essentially the same current level between 0% and 92%.
Again, here are a few mid-way readings, as well as the extrapolated capacity assuming perfect efficiency:
N/A13475 mWhnever reached100% (charge current at 0.0 A)12341 mWh~92% of rated capacity100% (first reached)11982 mWh~89% of rated capacity92%11398 mWh12389, ~92% of rated capacity81%10053 mWh12411, ~92% of rated capacity62%7646 mWh12332, ~92% of rated capacity50%6174 mWh12348, ~92% of rated capacity33%4100 mWh12424, ~92% of rated capacity
Oddly consistent, this ratio between charged power and percentage charge, at around 92% of rated capacity throughout almost all of the charge cycle.
The total power required to reach 100% is very disappointing. Even assuming perfect efficiency, it is well below the battery's rated capacity. Assuming similar efficiency as the S5 Neo at around 90% translates to roughly 80% capacity at full charge. This mimics closely the estimates from AccuBattery, which shows 78% capacity after 12 "full" cycles.
To reach a "saturated" 100% requires equally much power for the S5 Neo as for the S9+, even though the S9+ should have a battery with 25% more capacity.
Now that I have externally validated that my 4-year-old S9+ is only ever able to charge my fresh newly replaced battery to 80% of its rated capacity, I suppose the optimistic view is that it's now a forced charge limit for substantially increased battery longevity. While this is functionality I do want, it is something I'd prefer to have the option to use, and with the ability to top up to 100% when necessary.
If I have the opportunity, I may drop by a Samsung service center and ask if there's anything I can do to reset the battery status, or retrain the phone's perception of battery capacity.
Thank you for coming to my TED talk, and have a great day.
