Battery Charger for my i9000m

I bought a momax 2700mah battery and Now i'm not 100% sure that the battery will charge via my phone, even if it does. it'd be nice to charge my stock battery for backup.
I'm looking into : Wall Charger
and this thing: Usb Charger thing.
I'm not really sure what to get tbh.

if it's the same voltage as your stock battery, I don't see a reason not being able to charge using the phone.
Anyway, it seems that both will work.
Also please make sure that you keep the replacement battery charged, meaning that if you're not using it make sure to recharge it once a month.
These batteries can break down if their inner voltage drops below a certain threshold.

the sgs has been known to detect some batteries as non genuine and won't charge them.

I buy a 2430MAh batery and it works fine with me. It have the same voltage of the original 3.7!

I recall IBM laptops doing so for various hardware types; will Samsung do the same??

I've read that it is detrimental to the battery's life to store it while fully charged, just as it would be to store it while dead.
Since we're giving differing advice, I would suggest the OP look it up himself.

It seems to be hit or miss to whether or not the sgs knows it's not a genuine battery.. maybe it's a slight difference of voltage that triggers it, and it seems that it's the cheaper batteries that trigger it and the "oem" ones.

I've heard both, but going by my retail experience with these types of batteries. Most come precharged anywhere between 30-70%, so I can only guess that that is around the preferred charge percentage for maximum life of the battery as batteries don't move all too fast from the shelves. Heck my sgs had 70% off the start.

I use this for my Stock Batteries (1x 1500 mAh & 2x 1650 mAh) since April. No problems till now. It's not the best quality but it's enough to load your accus.

Question about Mugen Battery 1500mah

I'm very curous about this battery for Desire HD. From my experience, 3rd party batteries are generally frowned upon because they usually either
1) Does not contain the advertised charge (mah) amount
2) Does contain the advertised amount of charge but the battery spoils fast, and would be unable to hold charge properly after a few months of usage
3) Heat issues, etc, safety issues in general
It seems like many people in this forum have already got the battery and would like to know whats it like so far. my current original DHD battery has already semi gave way after a year+ of usage, it no longer hold the charge proper and I can only charge up till 60+% before it jumps straight to 100%, as well as battery level jumps erratically.
I went to check, seems like the mugen 1500mah battery http://www.mugen-power-batteries.co...ery-for-for-htc-desire-hd-softbank-001ht.html cost around $45 US which translates to roughly $56SGD whereas locally the original DHD battery costs $59SGD. Adding a couple of bucks for shipping and all, it definitely works out to be a better battery to purchase if it actually works well (e.g. refer to above criterias).
So I would like to know whether the battery suffer from the problem of holding charge and also any heat/security issues. Considering I've read that many people claim that they get a lot more battery life out of it in their initial usage.

If you can live with a modified battery cover then this is superior to the mugen battery and cheaper too:
http://forum.xda-developers.com/showthread.php?t=1344761
Big advantage here is you can use an original sensation/evo3d battery from HTC and don't have to have rely on 3rd party batteries.
On the other hand you can get as much as 1900mAh instead of the 1500mAh mugen offers.

As a matter of fact I have skimmed through that threads and I don't find anyone talking about how the battery life performs after months to a year of usage. This is a common concern because many 3rd party batteries lose their ability to hold charge very quickly after a short period of time. Of course it can be argued that no one complained about it in the thread but thats not substantial enough. The uesr reviews thats stated in those thread that you have linked are mostly by new users who were "wow"ed by the battery and then stop coming over to the thread altogether.

Even if they would reply, you wouldn't be able to use their statements because you don't know how they treated the battery so far.
I received my Mugen battery lately and I will be handling it the way I learned from here:

I have been using the Mugen battery for about a month now, following their instructions on how to handle the battery during the initial charges.
First, you say "3rd party batteries lose their charge.... after months to a year". Well, my original HTC battery after one year, is - I estimate - about 50% of the new Mugen.
OK, a new battery will outperform an old one, but it's not just 3rd party batteries.
When I changed batteries, the OEM one had actually expanded slightly and it did not slide out of its compartment easily. So the OEM is not a perfect guarantee of a lifetime of high power and good behaviour
And, I spent the extra € on Mugen and not the 2000mAh cons from eBay - Mugen has built a reputation over time, it is built to a similar (or higher?) standard as the OEM's.
btw look for a coupon that is valid for 10 or 20% I recall off the standard Mugen price.

test1800mAh
Many businesses will pretend to be the large capacity, we choose the best choice in the factory, so the quality guaranteed some. I bought a nominal capacity is 2300 mAh, I test the actual can reach 1800 mAh.

does it give you much better battery life?

So if im charghing my battery and it jumps to 100 from 74pct it shows that my battery is in bad condition?

There's a lot of people that are satisfied with Mugen, even here on the board.
http://forum.xda-developers.com/search.php?searchid=12986796
I personally don't care if you don't believe that.

I used a battery testing widget when I first got the mugen battery about 2 months back...
It was around 1300mAh with maximum 15% deviation, stayed around that value for the charge cycles done during that period, for about a couple of weeks.
I'd say its definitely pretty close. My HTC battery was at 800mAh with maximum of 20% deviation by the end of 1 year.
(Deviation comes from the limitation of calculating the mAh if I'm not wrong. Because it takes value of the actual consumption / charging once every minute or so, it kind of either interpolates between values, or just assume the whole 1 minute being the recorded value. Hence the possible variation.)

Of course you don't, but no, ignorance is not a replacement for knowledge.
Actual testing (250 mA drain until shutoff voltage) shows Mugen to be wrong. Where is proof that you're right?
For the OP: http://www.amazon.com/Motorola-Univ...able-Packaging/dp/B00486MH80/ref=pd_sim_cps_6
That should give one full charge of the Desire HD from 0% to 100%. It's about the size of the phone, but thinner.
http://www.amazon.com/Anker-SlimTal..._1_6?s=wireless&ie=UTF8&qid=1334818005&sr=1-6
This should give around two to 1.75 full charges.
I would highly suggest going with genuine OEM batteries to get the maximum you can get. Always ask yourself: If it was so easy to get more battery capacity into the phone, why didn't HTC do it?

I have posted a screenshot of BatteryMonitorWidgetPro below, showing 1526 mAh of in-use value as complete capacity after 100% complete / 0% discharge cycles.
Also showing 1214 mAh with +- 41% deviation while on daily use, with no complete charge/discharge cycles that I made in the beginning, after I had received the battery on March 13th 2012.
So this is not the complete capacity; the upper value is.

They tested a Mugen battery, which consistently shows that they overrate batteries. By default, the rating of the battery is in serious doubt.

Your own phone is telling you that you're getting exactly OEM capacity, maybe less. Battery Monitor Widget extrapolates what it thinks your mAh rating of the battery is based upon the voltage and the mA consumed to get to that voltage. So far it looks like your battery is either OEM capacity or slightly less. The top 1526 mAh number is what the battery claims to have, not what it really has.

1. Your test app is proving you wrong.
2. Phone based test applications are a horrible idea, proper testing should be done with the battery charged outside the phone to 4.2v then discharged to 3.4v at constant mA drain. Multiply the time that it took to drain by the mA drain used to get your accurate capacity.

No. This is how the app works: This value (1214 mAh) was measured by not draining the battery completely anymore. If I don't drain the pack to 0%, the app cannot measure all the capacity. Simple logic.

Mi4c Real Capacity of the Battery

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

Should I consider the values from /sys/class/power_supply/bms/ valid?

Does that mean that my battery capacity is now only ~2000 mAh?

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_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:

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.

I never saw the oem parts of xiaomi on the internet but I dont know i hope this original.

I replaced the battery 3 times, still I only can use 2500-2600 mAh Capacity - help

Hello,
I replaced my old battery because it lost its 30% capacity. Then I bought 2 times original Samsung Battery and 1 time a super expensive battery from Germany.
Everytime when I test it, I use only 2500-2600 mAh capacity of my Galaxy S7.
I did calibrate my battery, cleaned the gauge multiple times, reset it. It didn't help.
I just notice that my phone charge only until 4.825 V. Do you have any idee?

Maybe a problem with the apps not the battery itself?
Those apps are not 100% accurate anyway, they cannot be as you never run your battery to 0% while the app is running

I used 3 methodes to measure it. I dont think so. How is your phones fg_full_voltage value?

There is a code you can enter to reset battery stats too
dial: *#0228#
Press Quick Start
Connect Charger so phone is charging
Turn Off the phone and leave off until battery is charged to 100%
Power on phone
Battery stats should be recalibrated

I did that already, hmm the location is /sys/class/power_supply/battery/fg_full_voltage and in the same folder 2*fg_fullcapnom shows the capacity of your battery.
You can be right with the inaccurate apps, but the apps showed me the real value with a lenovo zuk z2 and galaxz s8.That's why I'm worried

What is more likely? That the apps methods are not accurate, or 3 new batteries all have 2500-2600 mAh capacity?

43125 in fg_full_voltage
eBay only sell fakes fakes and more fakes, Amazon probably too, unless you bought an original Samsung battery from Samsung there is a high chance that all those batteries are not as high capacity as advertised

My battery life is terrible with my S7 flat, so I took my phone to the Samsung Official workshop, I thought that a brand new battery will fix the problem, the technician made some tests and he tell me that although my battery was fine with 80% wearing but my battery drain issue is caused by a faulty board.

I'm pretty sure you bought the fakes ones. Try to buy your 4th battery from a Samsung service center!

My Third is not a fake one, it has 24m Warranty and is Made in German. The problem is with phone and OS. Nougat won't let you use your all battery capacity. If you dont believe me, use accubattery you will get max. 90%.

Already told you, those apps are not accurate

Can you recommend a new battery?

Accubattery says that my phone battery is at 45% of it's design capacity and really it drains quick. Can you recommend where to purchase a new one? It's a KB2007.
Thanks!

FYI, Accubattery does not accurately measure the supposed design capacity as it doesn't know the 8t has two separate battery cells. So, I believe your capacity should just be double which would be 90. Accubattery reports the same for me. It says like 48 or something which I know for a fact that is not true, so I'm assuming it is only reading from one cell. Try Battery Guru.

I use Aida64 and it accurately reports my battery levels. https://play.google.com/store/apps/details?id=com.finalwire.aida64

That's fine, but can you recommend a place to buy a new battery and what type? My phone would die on me midday if I don't charge it.

I would use a different app to see what is draining your battery, but if it is truly a bad battery, then your best bet is probably eBay to find a new one. Afaik, OnePlus doesn't sell OEM replacement batteries for 8t, but I could be wrong.

Battery Guru says the same as Accubattery: the battery is at less than 50% of it's design capacity. If there isn't a 4500 mAh battery available then I'll send it in to OnePlus for repair.

You may have defective battery. I have no issues with mine + no overheating...and I almost give it no rest whatsoever.
