Edit or Change Battery Capacity? - Xiaomi Mi A1 Questions & Answers

Hi there,
So I replaced my original battery to a bigger capacity battery (6,000 mAh), and I've been looking for a method to change battery capacity information file for Mi A1 but to no avail. Hence, the capacity is still at 3,080 (even in Kernel Adiutor) and I believe the phone wont charge to 100% 6,000 capacity. There are methods for other phones, but it seems the file is different for Mi A1 (using Havoc OS btw).
Anyone know the file location or any method to change the battery capacity?
Thanks.

what type of battery did you install? I had to change it but I couldn't find one that was so big and I had to replace one that was the same as the original.
sorry for my bad english.

I bought and installed BN31 Rakkipanda with 6,000 mAh, hence the huge difference (almost twice the capacity).

Is that even possible? I mean can u think that they will put twice the size of capacity in same size? I don't think it's 6000mah. U may damage ur device after altering capacity value. Its there for safety

Yea, I don't think that it is really 6,000 in real capacity, it is a third party battery after-all. But my original one was toast anyway, and I had nothing to lose, LOL. After installation, the battery-life in real usage is almost exactly the same as the original one (with the same ROM and kernel), but I have hunch that the battery is still not using its real capacity. I know it is probably not safe, but the phone itself is a backup phone, and I really am curious about the battery capacity.
There were double capacity batteries in Nokia old-times (and they proved to be true capacity -most of them anyway-), therefore I have faith that android phone batteries could be the same.

Hello. You can charge the phone to 100% and then check for the battery voltage. If it is close to 4.2v it means that battery is fully charged.

Tried this, the voltage indicates 4331mV at 100%. Should I keep on charging or disconnect the charger?
By close to 4.2V should it be under (at 50% I peeked the voltage reached only 3.9) or a little bit over?

[IDEA] Charge button

Is it possible to make a small program that allows to toggle charge on and off ?
as far as i know...charging our Diamond isnt nothing positive toward battery life .
I know you can enable or disable charging in system/power
but it would be awesome if someone would write small program/script to do that so we can place shortcut in programs menu to toggle
There is a setting that allows you to chose to charge or not to charge when synced.

As far as I know... it doesn't matter with actual batteries.
If I look at my notebook (which is over 2 years old) where I charge and uncharge all the time - the battery works still fine.
I'm not sure if it's worth the work - if the battery life sucks after a few month (years..?) - you just buy a new one for a few Euro/Dollar. (Man! You don't have an iPhone...lol)
I've never had a mobile phone for more than a year - so I wouldn't care!
(But I'm pretty sure the actual batterys don't care either!)
Li-Ion batteries don't suffer from the memory effect in the same way as Ni-MH batteries do, so theoretically it won't harm to charge the battery whenever you want to, regardless of it's charge level at the time. They do have a limited amount of cycles though, a cycle is when it goes from full charge to full discharge. It's eventually going to wear out no matter how you treat it.

so basically what your saying is Li-Ion batteries cannot over charge and then eventually start to decrease in total battery life?
If so, does that mean my T-mobile Wing's battery just crazy?
It would have exploded if it could "overcharge".
li-ion has a limited battery life by itself, which doesn't depend on usage/charging.
but charging can shorten the battery life if done wrong. charging cycles vary depending on how empty the battery was. it looks something like this: (see wikipedia/google for specific numbers)
95% 1000000 cycles
90% 100000 cycles
70% 10000 cycles
50% 1000 cycles
30% 100 cycles
10% 10 cycles
0% 0 cycles
actually you can never reach below 30% because the battery or phone will protect itself whenever that point is reached and turn itself off.
conclusion: charge whenever you can!
ps: li-ion for cars only discharge to 70%, so the battery can actually be used for longer than 2 years unlike a cell phone battery, where it can be discharged to 30%.
Guys, this is silly. The battery will work with no problems for 2-3 years. Then you can buy another one or, more probably, another phone. There is no point whatsoever to not charging it when connected to the computer. As a matter of fact, this will only reduce its lifetime.

Cradle use and battery health

At the office I leave my phone in a cradle. When I get calls I remove the phone to answer and then return it to the cradle when done. My battery goes from 100% down to somewhere in the 90's then charges back to 100% in the cradle. Does this repeated process harm the battery in any way? I've read that these batteries don't suffer from the memory effect, but I'm still not sure if this counts as a charging cycle.

You should always let the battery run down completely some times maybe once a week.
Really? I've read on this forum that there is no need to do that with the new Lithium Ion batteries. I've even read that this could have a negative effect and you should try not to let the battery drain completly.
I don't understand why there isn't a proper battery care section in the manual. Its as if its some kind of voodoo science.
Perhaps not Once a week. But Once a "while"
The reason is that, Phone software uses approximation to calculate the charge left in the Battery. So over time, battery ages and software may not be calibrated to match with the battery's storage capacity. So draining the battery entirely and charging them fully gives the phone's software to assess the battery's health and recalibrate.
It's a lithium battery mate. The only way you can really damage it is by a complete discharge. So long as you don't switch the phone back on once it switches itself off due to low battery you needn't worry about anything else.
Also in theory the lithium batteries have a lifespan of say about a 1000 charges for example and everytime you charge it has one charging less left. This ofcourse isn't exactly how it is in practice but charging the battery alot wears it down. It isn't good either to keep it in the charger for a longer time after it's reached a 100%.
Hi,
this is only partly correct:
Suppose the battery can make 1000 (which I don't believe) charge cycles,
it means that you can charge 1000 times from empty to full.
If you just charge 1000 times from 50% empty to full it counts for 500 cycles!
So,
don't worry, let it stay in the cradle if you like
There are 500 opinions about that but believe, as I wrote is correct.
Theo
Yes, what I said wasn't exact science and I used 1000 cycles as an example, but from what I've read it is better to let the battery drain to less than 50% and then charge it full rather than charge 5% at a time. My previous post was meant to illustrate this.

That's a load of crap, no offense... Lithium batteries have no memory effect and have absolutely no need to be completely discharged, that's a ancient thing from the time of nickel-metal hybrid batteries. The only actual reason for full charge cycles is to calibrate the device for that exact battery.
Keeping a lithium-ion battery in a charger most of the time will wear the battery down faster than getting it drain more and then charging it. Keeping the battery almost fully loaded/in a constant loading state wears the battery capacity by approximately 20% a year (can't recall the source/study just now)(EDIT: and my personal experience is that the battery capacity will wear that much anyway, no matter how you use it). The life-cycle of phones these days are roughly two years nowadays so IMO you can keep it in a cradle with no worries, if you wish. And lets face it, a new battery after a year of usage won't be that big an investment after all.
To add to the above post, running down a lithium battery completely does more damage than benefit. This is almost impossible though with normal use as the phone shuts down long before the battery is completely empty

[Q] Buying new battery

Dear readers,
I am going to buy a new battery for my HD2 but there is a problem.
I would need to train the new battery and charge it full the first time without turning on the HD2 right?
How can i do this when my HD2 keeps turning on by itself? I even think my phone charges when it is off?
My phone runs ics 4 with magldr.
Can anyone help me out?
Just drain the battery normally and charge it when you sleep?
Draining a new battery will make it unusable???
No it will be fine, Li-ion are quite durable & do not have charge state preferences.
Just buy a new battery & put it in your HD2 & use it normally, if charge very low when first turn it on > plug it in & charge to full.
Then why do people and retailers keep advising me to fully charge batteries before first use?
Cause batteries don't come fully charged?!
But if you charge it first how do you know the battery is fully charged without draining it first since battery stats are incorrect?
Hmmm, i have been told that fully charging it at the first time before first use gives u better battery performance and better battery stats. U are telling me the opposite thing lol? You could see it is full by the constant green led? But if it is like you are telling me then that indication would be false?? Do i get it right?
A new batteries capacity should increase after first few cycles as will devices calibration of the new cell.
The Battery itself is dumb & you can use what method you like really with li-ion cells to charge them.
Only issue sometimes seen is devices recognition of cell power level is not shown correctly.
Have recently issued 20 new cells for our HD2 fleet, staff use them as they needed & without stringent charge routines & all is fine.
A little common sense is all that is needed & maybe calibration reset if a problem appears.

What if you get a fake/defective battery that only holds 40% capacity and reports that as 80% and you charge the battery to report 100% (which activates the green led). How would you find out that this battery is holding a real 100% charge without draining it first?
With an app that shows u the amount of mAh?
Or is that impossible?
Any app calculating mAh will need a few cycles of the battery to give an accurate estimate. Reading any data direct from a cell is pointless as the cheap cells use chips to display false capacities.
In your circumstances just install new battery & charge while device is on then charge as required & only worry if run time seems very bad.

Now thats major bull. No app can give 100% correct info about battery capacity.
The only one method of correctly defining battery capacity is by using computerized battery analyzer.
If you want to get most of your new battery(Li-ion/poly):
-first make several charge/discharge cycles(after 5-10 you will get desired OEM capacity)
-charge it with wall charger, do not charge through USB
-charge it whenever you can, even if few % are only used
-avoid complete battery discharge(Lithium cells hate complete discharge!)
-keep it at reasonable temperatures, dry
-and don't buy cheap/promising alternatives. Only OEMs are worth buying. Forget about Mugen Magic(proof: www.batteryboss.org)
Battery apps are not always acurrate. They only measure in certain intervals (and then estimate the other stats), which only tells you the current in that instantance of time and the rest is ignored. Also if you undervolt, sometimes the drain measured higher than usual and the battery percentage becomes erractic (ie increasing after a reboot) that will easily change the estimated capacity.

Extended Battery with 5600mah not reccognised

Hello,
I've bought an extended Battery for my GT-I9505.
My Problem:
I don't feel anything of the power increase from the new battery... It's still discharging between 8-10 hours like the Stock one.
I deleted the batterystats.bin,
I calibrated the battery,
I charged and discharged it completly several times,
After a quick research I got the Information, that I need another Kernel, becouse the Stock one don't accept the bigger battery (the kernel think the battery is full charged but the battery isn't really.)
And if I combine 1 and 1 my thought is:
The more the battery is charged, the more the output voltage.
The Mobile recognise if the battery is full to avoid an overloading.
This recognise is taken from the output Voltage exact like the percent scale.
When the Stock battery reached his 2600mah capacity the output voltage is for example 4.000 Volt.
2600 mah --> 4.000 Volt --> 100%
BUT HERE IS THE PROBLEM:
As soon as the 4.000 Volt ≙ 2600mah are reached with the new 5600mah battery the mobile thinks its full charged to protect from an overload.
And I think, that the Battery isn't really full even if the mobile says that.
Can anyone help me?
I'm don't think this is the case. I'm pretty sure there are people using extended batteries on stock ROMs.
Could it just be that the capacity is fake?
Not really... The battery has good ratings on ebay

No its from mtec

Battery capacity lower than expected.

Hi all,
Using AccuBattery and it's telling me the battery is around 4160 mAh (that's from three charges so far). Obviously it should be around 4500 mAh.
Anybody else see this?
Thanks
I've installed the app to test your problem. It detected the correct battery capacity for me. The app tells you that you can adjust the battery capacity, probably because sometimes the reading is wrong.

No, no you misunderstand.
It detects 4510mAh which is correct. Once you've gone through a few charging cycles the app will tell you the actual capacity of your battery under the "Health" tab.
Me too, Accubattery says I have 4220 mA battery. Its around 5% less than original capacity (4510).
I see when battery is full charged, battery down from 100% to 99% quickly. On oneplus 7 pro I had the same problem, battery was "old" and OP7pro lost 5% quickly.
I don´t think it is enough to return the OP8pro, I will buy a new battery in the future when battery is older.
They use battery designed for max 4.4V. Advised capacity is correct if battery charged to designed maximum voltage however there is software limitation and you cannot charge battery over for example 4.275V in 7 pro. Real capacity is approximately 10% lower than advised. You have to understand that Oneplus is Chinese company so you cannot expect any reliable and trustworthy information from them.

4042mah on my one... But battery life has been great... It seems the voltage limit thing is the main reason.
4440mAh on mine.
Many reviews in playstore says similar problems on many phones.
Seems this app is not really accurate.
Thanks all
On new Pixel 4 XL I had 3850 mAh according to accubattery and 4100 mAh on LG V50. This measure is quite reliable after long time usage and you gonna see quite similar results like using usb meter. On my 7 pro I had 86% designed capacity and I have bought new battery - still 88% but when I noticed what's written on battery label all happened clear. Please never believe Chinese people even if it is global company they always lying because of they drink lay whit mother's milk and it's strongly correlated whit their totalitarian culture.
I just did 3 charges on my new op 8 pro and i'm getting 4419 mah ... :S
I did around 5 charges and mine is 4084mah, battery life is not great...
It's not accurate lol, don't trust it
