How do you override the default android manufacturer info on battery capacity?
E.g
I'm using Xperia C5503, rooted of course. Original battery comes with 2300mAh. I've got a new fatty 3rd party 3400mAh but the Android gauge simply can't get the correct reading of the new battery capacity. I tried setting the new capacity inside of 3C battery monitor pro but seems it's only for internal comparison, calibration also doesn't help probably because it's only meant to calibrate original 2300mAh not anything more or less.
So the result is reading stuck at 1% lasting for 10 or more hours, it's really frustrating. Any ideas?
Well, to reply to myself - I found it.
The solution to 'fix the gauge' with extended battery is to not let it drain to 0% but instead to drain only to the low battery indicator! I used 10% remaining indicator mark (didn't tried with 15% as suggested @batteryuniversity or 5% when battery saving mode switches on), then the crucial point is to switch the phone off and let it recharge in powered off mode till 100%. Repeat the procedure 2-3 times and it should be good.
The charging circuitry needs to learn what the max and min are, so it can then stretch its range to fit the battery's new and much larger capacity.
As a result now I have 3400mAh that holds around 3d6h with more than 8h of screen time. Hope that helps to someone too.

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.

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?
I've just started cycling with accubattery will post when I get some solid data but seems battery has lost some capacity already only had it since November 5

Heres mine so far only a few cycle's in but I've lost quite a bit capacity
OK, first of all, we all know that the S6 has NEVER been known for being a battery life champion. BUT, here's the problem .....
Battery reports relatively consistent decline in charge over time, until it gets down to 1%. At that point, the device still has sufficient charge to run for about one hour with the display on and set at full brightness.
Same on Stock Nougat, L.O.S 14 and L.O.S. 16. Same after full factory re-sets on all three. Same on pull and re-connect battery, which is a factory-new Samsung replacement for the original (not the 7 edge mod)
OBVIOUSLY, there is something not quite right about battery capacity reporting here.
Suggestions?

Ion Lithium batteries do not like to be completely discharged, to my knowledge ideally they should always be operated between 20% and 80% of their capacity.
Some laptop's do shut-down them selves when battery reaches 5% to safe guard the battery health.
So, yes, 1% reported by the battery does not actually include the "reserve" charge to prevent damages and, unless you really have to, do not use you phone with battery below 10% and charge it !
Under normal circumstances

Under normal circumstances, yes, definitely, keeping it between 30% and 80% is ideal, but when the goal is to accurately calibrate the battery / charging monitor circuitry, more accurate results are to be obtained by running the device to the point of battery exhaustion, at which point the reserve capacity designed into all lithium batteries still remains. But this is NOT something to think about doing on a daily basis. An S6 or S6 edge first run to the point of shutdown will actually re-boot but shut down just about immediately thereafter - iterations are not advised. You want it to have just enough left to get it to re-boot and stay running while charging, at which point you can monitor the recharge . Check out the data from Battery University or the support pages for Accu Battery for more details. Trying to use up the built-in safety margin is a fool's errand, and if you've ever seen a mishandled lithium cell turn a vivid red while the device in question melts around it, it should give you a healthy respect (if for some reason you did not have it in the first place) for not messing with or even attempting to mess with the reserve. The problem here is that the "1%" remaining on the charge meter (which is above, beyond, and independent of the untouchable reserve) actually appears to represent about 15% of the rated capacity of the battery, or in this case, over an hour of screen-on run time, and by never running that out, a current-flow-based app like Accu Battery will invariably under-report capacity going forward as a result. Such apps measure how much current is drawn to get from 'x' percent to 'y' percent being reported, but when the amount of current draw to get from 1% to zero is a range of around 300 mAh, for a battery nominally rated at 2,550 (for an S6) or 2,600 (for a S6 edge) as the total capacity, the problem of how accurate the "1%" figure is should be kind of self-evident. I am not willing to see how low a "0%" capacity report can be pushed down. Sanity has to rear its ugly little head at some point, after all.
Many alternative kernels, etc.. claim to address this problem, but I have yet to find one that actually does the job. It is rumored that Samsung service facilities can do a complete reset of the capacity reporting capability, but who knows? Maybe the luck of the draw gave me a dud battery from Samsung as the replacement. :crying:
Hi, I've been having problems recently with my ZTE Blade Spark (Z971). I only have about 3-4 hours of battery life with active use (browsing the web or watching videos), and this is with screen brightness turned to the lowest, airplane mode on (though wifi is on), etc. I've been using this phone for about 2 years, and it was much better before. The battery is supposed to be over 3000 mAh, but according to AccuBattery, my phone is only charging to about a third of this capacity. Also, when I tried to calibrate my battery, I noticed that when I ran down my battery to 0%, and plugged it in, the on screen indicator immediately showed ~30%. However, when I immediately unplugged it and tried to turn the phone on, it wouldn't turn on. Calibration didn't really work either. Is there anything I can do to fix this?
Two years of use will usually kill 30-50% of the battery capacity.
Accubattery can tell you the estimated capacity on the "Health" tab.
It may be time to change the battery.
But this is a lot worse than 30-50%, according to AccuBattery, im only getting a capacity of about 1000 mAh, which means the battery lost around 2/3rd's of its capacity. Is there anything I can do to fix this, or do I have to replace the battery at this point.
Couple of weeks ago I changed battery on my phone and everything was fine until phone was at 20 percent and thats when it turns off it is happening since I replaced battery and since then I found that battery is actually 5000mah instead of 4000mah on orginal battery that came with phone. So I tought that maybe phone turns off because it thinks it is on 0 percent charge because the phone is set to use 4000mah battery and I was wondering If there is any way to modify capacity to match with the new battery and maybe that way stop the issue
I doubt it's 5000 mAh unless it's physically larger than the original or a different battery type.
Allow it to run till auto shutdown then charge to 100% three times.
Is your SOT good now? That's what really matters. If so I wouldn't worry too much about it. 20% is a good low cut off voltage as it reduces the strain on the battery.
Check the cell's full charge and auto shutdown voltages. Is the battery itself shutting down prematurely?

It is different type of battery than original new one is dual cell and SOT is better now also did charge it from shutdown to 100 three time already full charge when left charging overnight showed capacity of little less than 5000 but dont know how to check autoshutdown voltage and if battery is shutting down prematurely

Best to always go with OEM or as close a match as you can. No reason a dual cell parallel connected be superior to a single cell unless it's a different battery type. That could throw off the preset power controller values. An interesting mystery.
If your SOT is the same or better than the original battery when new I wouldn't worry about it. Especially if it causes no operational issues. Battery voltage can be seen with various 3rd party apps like DevChek and Accubattery.

Yeah but sadly there were no single cell in the shop and voltage is 3.8 but i find it little frustrating when it turns off 20 percent instead of 1 it just a little inconvenience
