Ok, so my friend has an Evo 3D, and I have a sensation, this made it easy for us to buy battery's since thy're interchangeable. So we looked for the highest capacity battery and found one rated at 2500mAh.
http://cgi.ebay.com/2-X-2500MAH-Bat...ltDomain_0&hash=item336a412ba9#ht_1491wt_1395
So they just came in today and they're the same size as the stock oem one, but as I popped it in and charged it up, I was at 100% battery for 3 hours straight, followed by a semi-steep decline in battery life.
But as I read other threads, you can peal the sticker off to find a S/N that could give away the real mAh, so I've attached pics of what I've discovered and how my battery's faired all day.
Oh, and I'm running LeeDroid 2.2, freaking amazing rom.
Just wanted to post what I found.

A while, about 1:30 - 2 hours, I used maps for 30 min, then just checking email and reading some engadget.
If i remember correctly, the true mAh on the S/N is the last 4 numbers on the 2nd set of numbers.
So, your battery is only 1700 mAh instead of the 2500 mAh as advertised.

Dang that's disappointing, but better than stock so I can't complain!
Hmm.. 1700 mAh
not 2500mAh.....
Anything is better than stock....
I would tell people to stick to the chichitech or anker batteries.
perhaps it means 2x 1700 mAh = 2500 mAh with a light error in calculating ^^

Yeah right. LOL.
I can't see 2500 mah fitting into the same size shell. Batteries with that sort of specks usually require a new battery cover. Just look at the phones that require a new cover of with batteries near the same power output.
At least you do have a battery that gives you more up time than the stock though.
Think I'll be with the chichitec, myself.
Congratulations, you bought an anker/chichitec, according to those numbers they're all using the same cell, and they're all exaggerating the mAh ratings.
Btw stock is 1520mah
How important is it match the voltages in replacement batteries? I thought it would need to be exactly the same?
I'm replacing a battery in my friends Huawei Ascend P1 U9200. It's current battery specs are:
HB4Q1 Battery, 3.7v / 1670 mAh
However, there is also listed by many resellers another battery which they say is also for U9200:
HB4Q1HV Battery, 3.8v / 1800 mAh.
The HV model seems better for capacity but I'm worried the different spec (voltage) may damage the phone. I'm being a bit paranoid because it's not my phone and I'd feel bad if I fried it :silly:
The battery in my V10 is 3000 mAh. I saw one on Ebay that claimed 3800 mAh. Is that possible in a battery this size? I know a lot of off brand name batteries inflate the numbers to sell them. I wonder if this is the same. Do any of you have a standard slim battery that is over 3000 mAh?
There is batterys for the LG V10 that can go up to 9000 mAh and higher. They are NOT inflated numbers. The only thing about these batterys is that you will have to have a thicker case.

I tried it but the stock battery lasted longer. I don't recommend it and if anyone else finds a another brand let me know. I'm always willing to try all available options

Right now I want a standard sized battery, highest capacity possible. I have only seen one option like you are referring to, and I do not like the case. We will probably see more options in the future as this is still a new phone model.

I am sorry to say, but until the technology progresses, the battery will only increase in size as the mAh increases. IF the 3800 battery you speak of is the same size as the stock battery, it is bull**** and will not be 3800 mAh. If its a shady seller, it could be a even less than stock. Please be wary of these people in the future.

I agree with you 100%! I am still willing to bet that a battery can be made with a higher capacity than the stock one, and have the battery size stay the same. There is a limit to how much capacity can be squeezed into a battery this size, and as you say, when that is exceeded, the battery size has to increase. I just have not owned a mobile phone in a few years that had a removable battery. I was able to find higher capacity, standard sized ones in my other phones, just hoping I will find one for the V10 that is actually the rating on the battery. Amazon has several that are rated as 3300 mAh, but I am not sure if the performance difference on those would be noticeable, even assuming that the specs are legit. If somebody comes out with a super high capacity larger battery with a good case, I may try that.
Well 3300mAh is maybe real. I noticed that the stock battery continues to charge for around 1 to 1.5 hours after you see the "battery charge complete" message. Looking at the charge current with abttery monitor widget it looks like the stock battery when charged fully till charge current becomes zero has in fact 3200 to 3300 mAh capacity. When i do this i also see that my battery sits at 100% for several hours before starting to drop which confirms that. So maybe these 3300mAh batteries are really with such capacity but nevertheless they will not give you better battery life than the stock battery.
There is one application that estimates you battery health and size after a charging session, it keeps telling me that my phone is 3799 aka 3800 not 4000, can any of double-check? It's called accubattery on the playstore.. Is there any other app that can do that so I can recheck
I guess some models were released with lower capacity batteries which means you're doomed.

You're probably fine, have you tried another app to check? I'm using aida64 and it reports 3900 mAh
Batteries are not a precisely defined size. It's not like they are machined out of some material to an exact size. They are a bunch of messy chemicals and there will always be some variation in capacity.
It's up to the manufacturer's honesty whether they specify the minimum or average or maximum capacity.

Maybe yeah, but 200 mah is too much, when my s7 edge was 3680, even more than advertised
So you guys don't think it's a defect or something? Worth checking out?
I doubt it's accurate. On my current phone which is over three years old it says the capacity is still 3000 mah like the day I bought it. That would be an incredible feat but very doubtful.
Your battery is fine, don't worry about it.
If it shows 3400 mAh in a few months, well...
Thank you guys, I'll keep it and keep checking every month, if its getting worse then I can always check with my warranty provider

Same here. At the moment accubattery is reading my battery at 3741mah 94% life.

I use the same app for all my Android devices (I set a charging limit alarm to 80%). In the first couple of days I had my Mate 9 Accubattery was reporting 3920 mAh. I uninstalled and reinstalled it thinking there was something wrong. Then the next time I installed it it was reporting lower capacity of 38xx mAh. So I just ignored it and let it run. A few more days go by i randomly checked it and now its showing 4002 mAh 100% health. So I think it has a break in or calibration period for it to properly detect the actual size of the battery

There is a reason for that and the explanation can be found in the app itself. Some manufacturers report a lower size battery than the actual battery size. Therefore you see the health is still at 100% although it already has degraded.
My battery shows 3850 and 100% life battery since the first day I got the phone. It last 2.5 days with medium/high usage. it took me a while to optimize all the apps I have installed in the phone tho.
in my understanding the number that gets reported to the app isnt the real capacity but the capacity keyed in to the Kernal file. Nothing to worry about guys.
Mine is still only takes around 3750mah worth of charge using Accubattery.
I remember some blurb that battery manufacturers have some %10 or so leeway in what the battery actually delivers versus what's written on it.. I wouldn't worry about it; what's 200 mAH between friends?
I did speak with the Huawei support center regarding my battery only taking around 3700mah charge and they informed me that it's normal and it's for backup.
That does not make a lot of sense but I do understand there are manufacturing tolerances. The battery in the mate 9 is rated for 3900mah with a typical capacity of 4000mah. So going from 3900 to 3722 on my last benchmark charge isn't to bad.
Hi to all,
I just wanted to make a debate about the real capacity of our phones batteries.
That's because I found an app that allows us to measure the real capacity and I found a quite astonishing result: it seems like my battery has the same behaviour as a 2200mAh ones!
In fact, with all connection active (Bluetooth, Wifi, LTE, synchronization..) I barely reach 3h of SOT daily.
I used 3C toolbox (https://play.google.com/store/apps/details?id=ccc71.at.free) using the instructions in this answer (https://android.stackexchange.com/q...ity-of-a-battery-in-mah-received-fake-battery in "How to measure actual capacity using 3C Toolbox").
Also if you can advise different apps and methods to do this, I would be very happy.
Thanks to all!
The real battery capacity is the advertised one. 3000-3080mAh.
Xiaomi uses lower binned batteries which degrade a bit faster over time. An app can't measure the real battery capacity or estimate it accurately. The SOC we have is power hungry and inefficient, that's why it's so hot too.
I think it's 1500 mah or something like that. I get only 2 or 2.5 hours screen on time. The results has been never changed which i've tried several roms.

Well, the app don't measure the battery capacity, but how much current flows in when it's charging.
So you're saying that the main problem is the age of the battery..
Do you think that changing battery may improve the result?
3h sot is normal, when used from morning till evening. When used continually, I get 5-6h sot. An app cannot accurately measure battery capacity. This phone, like many others, is built to last a day with moderate usage...

Hello, this is a very interesting topic, so I decided to check the real capacity of my Mi4c's battery with one of these. When the phone turned off at 0% I recharged it to 100%, while still off, with the following result: 1.76Ah @ 8.8V as I was using a QC2 charger. Let's translate it to the battery's 3.8V assuming 80% charging circuit conversion efficiency:
Code:
((8.8 * 1.76) / 3.8) * 0.8 = 3.2Ah
My battery is 6 months old and seems to be slightly better than specified.
If you use a 5V non-QC charger try one of these to measure it and assume higher 90% efficiency. Android battery apps are useless, please check it out with a hardware meter...
:highfive:
I'm already running third battery with my mi4c, all three tested with a similar hardware meter:
1. original battery, but already with signs of being worn out (shutdowns, sudden voltage drops) ~12Wh, not tested as being new
2. aliexpress replacement (getting worn out after 3months of use) ~13Wh
3. some battery I've got at local online shop that seller claims to be original (not 100% sure, but dimensions and weight match the original one) - sligthly over 14Wh
4. -another mi4c, as it was brand new- just over 14Wh from empty to max; surely the battery is in good condition as the one can reach 6h SoT
and I've tried different chargers (QC,non-QC) and no go - no way to see 15Wh or more being transmitted in one charge on both mi4c's I've got at home
Find out about battery behaviour of Nexus 5x, as its specs are very similar to mi4c's and compare battery capacity and standby/sot

And our battery behavior is a lot better.
Should I consider the values from /sys/class/power_supply/bms/ valid?
charge_full = 1983000
charge_full_design = 3071000
Does that mean that my battery capacity is now only ~2000 mAh?
EDIT:
charge_now_raw reports 2952776 when my battery level is 98%. So something is definitely wrong there.

cycle_count: 20430
resistance: 279541
esr_count: 63

voltage_ocv: 4323094

Your results are fine but you're not accounting for the efficiency of charging which also decreases with higher...
charger's voltage
meter's internal resistance
connecting cable and contacts resistance
My 15.7Wh on the meter is actually around 15.7*0.8=12.5Wh on the battery.

Some of them are definitively valid, others depend on type/firmware version of the control chip integrated in your battery. Here are mine:
Code:
POWER_SUPPLY_NAME=bms
POWER_SUPPLY_CAPACITY=51
POWER_SUPPLY_CAPACITY_RAW=5143
POWER_SUPPLY_CURRENT_NOW=432278
POWER_SUPPLY_VOLTAGE_NOW=3837410
POWER_SUPPLY_VOLTAGE_OCV=3874031
POWER_SUPPLY_VOLTAGE_MAX_DESIGN=4400000
POWER_SUPPLY_CHARGE_NOW=0
POWER_SUPPLY_CHARGE_NOW_RAW=1481002
POWER_SUPPLY_CHARGE_NOW_ERROR=98504
POWER_SUPPLY_CHARGE_FULL=3101000
POWER_SUPPLY_CHARGE_FULL_DESIGN=3071000
POWER_SUPPLY_TEMP=285
POWER_SUPPLY_TEMP_COOL=0
POWER_SUPPLY_TEMP_WARM=450
POWER_SUPPLY_RESISTANCE=110778
POWER_SUPPLY_RESISTANCE_ID=50306
POWER_SUPPLY_BATTERY_TYPE=x11_atl
POWER_SUPPLY_UPDATE_NOW=0
POWER_SUPPLY_ESR_COUNT=64
POWER_SUPPLY_VOLTAGE_MIN=1
POWER_SUPPLY_CYCLE_COUNT=0
It was measured with the power gauge at around 55%. My CYCLE_COUNT is surely higher than 0 after 6 months of use, and your CYCLE_COUNT=20430 is simply impossible
I'd more believe your charge_now_raw = 2952776 than charge_full = 1983000.
Incidentally, the simplest way to get these stats is from TWRP in ADB:
Code:
adb shell cat /sys/class/power_supply/bms/* > bms.txt
Hey guys, long time no see
I did not see the thread, but i went on with my speculations on the same matter.
I bought this from amazon https://www.amazon.it/gp/product/B00NPVZHAO/ because i wanted to test my day-one mi4c battery.
It has roughly one year and a half.
Well...from 0 to 100% it gets a whopping 1617 mAh (see the attachment).
I was disappointed, but hey, maybe i had a degraded battery to start with, and since i never measured before i went on to buy a new original one.
Well, yesterday it arrived. changed it, discharged to 0%, charged to 100%.
Okay, it's only the first cycle, but...
1800 mAh
I guess advertised capacity is a long way from the real one?
After all, if this is correct my old battery degraded by 10% in 18 months...and that's realistic.
Please tell me i'm wrong.
I bought it for this job and I wait. But unfortunately there is not much hope
Nexus 5x has very similar specs and very similar SOT. Also, the original qc charger is supposed to charge using 5v,9v and 12v, not only 5v. What does that say about your research? Either both manufacturers lie, or you're doing something wrong.
I get anywhere from typical 3h(usage from morning till night) to 6h(continuous movie watching using streaming). For the record...

Code:
((8.91 * 1.617) / 3.8) * 0.8 = 3.03Ah
Which is exactly as advertised by the manufacturer.
No need to change batteries, your SOT is low because of the awful apps you use. For example, did you know that "uninstalling Facebook app saves up to 20% of Android battery life"? You can still use FB and its notifications without the app - read the article.

Thanks @k23m, i felt like a student again but after reviewing your formula you are right.
I though the tool's mAh measurement were already adjusted for the battery's voltage, but as you showed we still need to do some math.
I guess that i didn't need a new battery after all, but now that i have one it's certainly better!
I don't have issues with SoT, i do 5-6h on TS CM13 (i stay on marshmallow for xposed) but i just wanted to test battery degradation.
I will still post new battery results after a few cycles.
