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.

That is just your opinion.
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

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

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_VOLTAGE_OCV=3874031
POWER_SUPPLY_VOLTAGE_MAX_DESIGN=4400000

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...

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 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.

Where did you get the original battery? There are always fake on the internet.

ebay battery seller with 20k feedback 99%+ positive.
I never saw the oem parts of xiaomi on the internet but I dont know i hope this original.
Purchased UNBRANDED 3670mAh battery meant for the G4 Play (we use the same battery), will post SOT information/burn photos here.
https://www.ebay.com/itm/New-Rechar...la-Moto-G4-Play-XT1607-CellPhone/182477310377
Are there any reputable companies making a 3670mAh battery for our phone GK40?
here is moto g5 forum
you think the battery have the same dimensions?
Lithium-Ion 4550 mAh
Attached photos of purchased battery. Battery itself displays as 4550mAh with 3.94V reading from the multimeter. Can anyone identify the maker?
Confirming fitment in XT1676 and powering up, phone functioning properly. Will be doing a few cycles on the OEM battery to compare aftermarket results.
Bah! Of course they only ship to the united states.
where are you bought from? Thanks

Wow so nice to hear this..! Stock 2.8Ah is so small and barely makes a day. Do tell us updates if your "hack" becomes successful and also share some screenshots..

Hiya, any update on this? 4550mAh sounds too good to be true, but I'd love to hear how your mileage has been with this
Any source for that battery which sells to Europe/ Germany. Could not find one myself.
Just ordered this extended battery with 3400mAh which also delivers to Europe.

Unfortunately it turns out the battery is a fake. It has less capacity then original

You did a runtime measurement?

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.

Yea, I know. I agree
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 same issue !

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.
