I know the G5 is new but there is one that has 3600mah. Now I haven't tried that brand but i know a user who used one and loved it for his G3. Now you may want a Charger cause on my testing I charged the original battery and I got a SOTof 5HRs and with the USB CABLE I got 3HRs so yeah think about it

Nice find.
Look at my Thread on the G4 Thread for some Info.
Ok guys i added a LG G5 Battery TrendON+Charger to my First Post. Have Fun
Is those big batterys really bigger than normal or is it only like value printed to battery? Its weird that if its possible to add bigger battery with same size than original, why LG didnt do it then?

I'm not sure but you buy one to try out. My batteries for the G4 seem correct
Has anybody tried/tested these high capacity batteries?
Do they fit the phone? Do they last longer?
Got mine on Saturday and still can't tell yet.

Ive got the 3200mah battery but there isnt an app that confirms the actual capacity. As far as longevity...it feels the same as 2800mah honestly. I'll run a test and report back.
Uhh, judging by the images on the webpage that 3800mAh charging case isn;t actually made for the G5. It appears to have a microUSB connection instead of a type-C and also the camera cutout is completely wrong. I suggest removing it from the list unless someone has bought it and can confirm that the images aren't representative of the actual product.
As always be wary of batteries from random manufacturers on alibaba. Every single time someone's phone explodes in their pocket the investigation discovered it was a non-OEM battery from China.
From my experience with my old galaxy s3, any battery that claims to be a higher capacity than the stock and is the same size, normally is garbage. The fact of the matter is, if there was a way to get more power into the same amount of space, lg would've done it in the first place with the OEM battery. So unless you just want a cheap extra battery that may (or may not) explode, I'd suggest sticking with OEM or first party stuff.
Ok well my G4 with all these battery apps. They all tell the same capacity 2800mah as there's a chip in the battery/phones/kernel that the capacity stored and locked to 2800mah. Now I have an App. That you can edit the battery capacity in the settings. I'll link it in a few

No. That is not the case for 'every single' time a phone has set on fire at all.
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.

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.

Not a precise measurement. Orginal runs about a day. This one half a day with not much activity. It has a jump from 30% to zero. I had several full charges/ discharges before. And several attempts in trying.
lithium batteries should be kept between 30 and 90 %. It's worse to discharge them.
You could charge to only 80% but 90% is where on most phones the battery statistics reset

Sure, these are recommended usage conditions. But jump from 30% to 0% likely means defective battery, which cannot hold its capacity.
Normal battery should go smooth from 100% to 0%. Well, it may be not a straight line, but under constant average load graph should be near linear.
If it's jumping and suddendly goes 0% it's something wrong with battery. You may still try to calibrate it by full discharge/full charge several times,
but high quality batteries usually don't require it. Also I think high capacity battery must be thicker than original. If not, it's most likely a fake.

anyone found a decent battery yet? For Hiking I tend not to carry a heavy powerbank (even not a light one) but a spare lightweight battery... I do not understand why Lenovo is providing a changeable battery but not selling any...
Sorry, been away without notifications. Ran battery for several weeks and notice no significant increase in battery life - had screenshots of usage but unfortunately had a bad flash (Dont use SD as internal storage).
Decided to stick with the OEM battery, and will continue purchasing them if they go out or need to swap. Because of build quality, coping with a dead phone is better than one on fire or overheating.
But if Motorola or Anker releases an extended slim battery...
Hi, just wanted to ask if someone else beside me and my friend got a 3000mAh battery (According to accubattery) after a couple of months, the same happened to another friend of mine with a OnePlus 6T, 3450mAh instead of 3700mAh.
Screenshots attached.
Accubattery is insanely inaccurate, and takes an estimated guess based on charging cycles. Long story short, the app is garbage and people should stop putting faith in it.

I've already tried to search for a this app, and I found a thread in the OnePlus 5T section where a USB multimeter in, at least, two cases, has shown the same result as Accubattery.
Anyway thanks for the answer, need to find why battery sucks su much on both my friend phone and mine.

I experience the exact same issue on my oneplus 6. The accubattery app shows my battery health as 3,046 mAh and design capacity as 3,300 mAh. It has been this way since the day I got the phone (around one month back). I am pretty bummed that oneplus sent me a phone that had only 90% battery life to start with. Is that a problem with the battery or is that a problem with the way the accubattery app reads the results?

Seriously? As stated before it is a calculated capacity. It measures how much goes in and out. While the battery is shipped as 3300 mAh the app can very well vary as it is only roughly calculated and the full capacity is very theoretical as the voltage decreases and is never zero.
You start with 4.35 V = 100 % and end at maybe 3.2 V = 0 %. So you have energy left after your phone as shut down. That's why you get a battery low screen even if your phone has shut itself down. It is not a design flaw and it is not scam.
Also don't forget that different components use different voltages. Transforming them results in wasted energy. Like a power bank that has 10000 mAh in theory only can charge maybe 7000 mAh while the rest is lost in heat.
thank you !

thank you for your detailed analysis !
It's kind of reassuring because when I bought mine it was second hand and I saw around 3000mah as well! So actually the battery wasn't damaged probably.
It could also be OnePlus which makes the choice to not allow the phone to charge completely so the battery lasts for longer in long term. I Kno Dell does it for example. Then it would be very acceptable. But yeah, maybe it's the app.
Had the same issue with several phones, for example with the S8+, Accubattery showed 97% from day one, after a few weeks it dropped a bit lower still.
The app seems highly inaccurate and I quit using it.

Hi guys. Just wanted to ask a quick question with regards to. My Galaxy A73 and the accubattery health estimate.
Before anyone yells from the tree tops "battery monitoring software isn't accurate" I know that, but it's enough to get a general idea on how my battery is holding up. And historically it's readings have been pretty good with me. Recently slapped in a fresh 3000mah battery in my S7 and it pretty regularly reports the battery health in the 96-98% range (I typed in the correct capacity for the new battery) which I am happy with. So..... with thay out the the way!
Recently the entire family basically came up for new contracts all at the same time, and we all got A73s. So three phones for the wife, father and myself. I've installed accubattery on all three phones and done full charges, ~15%-5% up to 100%. And on ALL three phones the reported battery capacity is around ~4500mah which seems far off of the design capacity of the advertised 5000mah. My particular phone reported a first charge capacity of 4733. But has dropped to 4500 over subsequent charges. As I said. I know software isn't 100% accurate. But historically it's been good to me reporting good numbers for my S7 and my A80.
Although I have been very impressed with the battery life thus far im still wondering if these battery's are bad.
Can anyone else show their accubattery results?

Interesting.
So you are also seeing ~4500mah?
Well of that's the case then I don't think all these phones can have bad batteries.
So Either
1. Accubattery is reporting incorrectly. Not exactly far fetched as software can definately be wrong.
2. Our phones all have bad batteries. less likely but still a possibility.
3. Or lastly Samsung is lying about advertised capacity and we all have 4500mah batteries. I find this to be the LEAST likely scenario.

Sorry this is an older thread, but I've had much the same issue with quite a few of the Sammy devices, and found this thread because I've been considering an A73.
First, Accubattery, in my experience does a good job. I've used it on an LG G8 that I had done battery 'conditioning' since it was new. Guess what? Accubattery rated that phone at 103% of capacity! Yes, it was accurate. Also used it with a Pixel 6a and battery was 100%, so that one was rated at 4500 mah and that's exactly what Accubattery said.
But most of my Sammy phones, like the 2 A52S I have, are rated much lower than stated capacity. Instead of 4500, they both rated about 4100.
Your scenario number 3 is actually correct, but not in the 'lying' part. If you research it, ea mfg tells you that battery capacity can vary (they claim it's hard to control during manufacturing), and it states in their 'fine print' that a battery actual capacity can vary by 10% plus or minus (it's always minus).
That means my new phone, properly conditioned from the beginning, could read as low as 4050 and still be within specs. So it's not a 'lie', it's a way to put in less battery and still claim it's 'as designed' and you have no recourse.
Ironically though, my older galaxy A03, which has a 5000 mah battery, gets a 100% capacity from accubattery. Sometimes I think it's a better idea just to use them and not even think about it. It's kind of tedious and it's pretty much out of our control. And life is short.
