What I found on Anker battery..is this the real capacity?

I just received my Anker battery from Laptopmate (ebay) today.
And surprisingly when I look on the cover, it seems there is a print out that is transparent from the back..and it shows number 1700.
Does it mean the real capacity of this Anker battery is only 1700 mAh?
The whole printout reads:
H0545148AR
TIF09NF1700 (I can't read clearly the first 3 letter on this second line)
Can anybody who receive this battery confirm this?
Does yours also show similar printout?
I attached the pictures for you to see.

Very interesting, I was going to ask someone whether they would tear off the labels on their batteries to look for serial numbers.
I've purchased 3rd party batteries in the past that had labeled capacities that were exaggerated versus the data sheet corresponding to the serial number printed underneath the label.
I believe that 545148AR may correspond to the battery listed in this document,

Here is a description of the datasheet from a different datasheet I have from the same company.
Notes:
1.Rated capacities of above batteries are measured according to the following conditions:
under 20+5℃, battery is charged to 4.2V with constant current of 0.2C5mA, and charged continuously with
constant voltage of 4.2V until the charged current is 0.01 C5mA., then discharged to the voltage of 3.00V
with constant current of 0.2 C5mA.
2.Under 20+5℃, 65±5%RH, rated capacities less than 1000mAh, it can be charged to 4.2V with constant
current of 1 C5mA, and then, charged continuously with constant voltage of 4.2V until the charged current is
less than 0.01 C5mA, then battery can be discharged to the voltage of 3.00V with constant current 1 C5mA.
The discharging time is not less than 54 minutes (or capacity is not less then 90% rated capacity); rated
capacities more than 1000mAh, it can be charged to 4.2V with constant current of 0.5 C5mA, and then,
charged continuously with constant voltage of 4.2V until the charged current is less than 0.01 C 5mA, then
battery can be discharged to the voltage of 3.00V with constant current 0.5 C5mA.The discharging time is
not less than 108 minutes (or capacity is not less then 90% rated capacity)
3.Among models of the batteries mentioned above, the battery model labeled R is prismatic battery with
round angle； the one labeled A is the battery whose shell is made of Aluminum；the battery model labeled
S whose shell can is made of steel；the battery model labeled F is a set of explosion-proof；the one labeled
J means the battery is made by automatic line；the suffix of ''H,M,E,L or 1,2,etc" added to the model name
was to sort the capacity of the model which has the same size, and have no meaning else

It would be interesting if someone can measure the dimensions and weight of the battery and compare it to the datasheet values to determine whether its the same battery or not. If the true capacity is actually 1650mAh, I would not be surprised at all based on my experiences with 3rd party batteries.

Guys I think the biggest thing to keep in mind about these Anker batteries, is that it seems to be a fairly unanimous consensus that these "1900" mAh batts are giving people longer cycles.
I spent a few hours today reading ALL the posts about every 3rd party battery for the Sensation, including the Evo 3D batts that work in the S4G. This Anker seems to have to mostly positive reviews by XDA members. Ya its a roll of the dice....but for under $20 to have possibly 4-7 extra hours....that's well worth it. I purchased one today....when it comes, ill give my results.
That faint number you see, that no one else seems to have noticed in the thread on Anker, could very well just be a random number....who knows.
Main thing....it seems to act like a 1900mAh battery

Hoping to love this $18.99-worth
I just bit the bullet and purchased this from amazon.com. For the price point as long as it gives any increase in battery life -and- doesn't set my phone on fire, this will be a worthy investment. As a newly converted blackberry user, battery life on android os devices just kills me. When I get the battery I'll post an update.
First post on xda FTW!

why did you feel the need to open a new thread about this when we already got more than one about the anker 1900mah battery?

My only concern with that is that its all just anecdotal evidence, no one here has tested the battery under controlled conditions with the appropriate equipment. Can we really reliably tell +100mAh from +400mAh based on peoples undefined estimates like "light usage, heavy usage", not to mention bias. Ultimately though, it probably won't matter to people as long as they think they're getting better battery life, which they probably are, but maybe not as much as they think they are.

this may sound werid..i may get flamed at i apologize... but what are the chances that these batteries will blow up compared to the oem htc sensation ones? is it really made out of high quality?

+1
I am also very skeptical about the 3rd parties and how they "feel", once again I will direct people to this test, Battery Boss where many popular 3rd party brands are tested to have only 70-82% of advertise capacity.
However every oem battery tested is around ~96% of listed capacity.
Sure its only 10 or $20, but I would rather put that money towards a battery with a 'true' rating.

Let us not forget that if you turn your HTC battery over, it says...Made In China.
These Anker batteries probably come from the same manufacturer as HTC branded ones.... well it's very possible at least.
Seems like some people think that because it's Chinese...it's inferior to the oem HTC batts. One and same

$40 versus $10, one and the same? Maybe, but more likely wishful thinking. Remember you're trusting guys who are lying about the mAh ratings.
http://batteryboss.org/

Well, i can tell you this: Stock my BEST day was 14 hours with two hous of "screen on" (use) time. My first day on an Anker was 14 hours with 3 hours "screen on" (use) time.
Today, my second day on the Anker and I am at 64% at 9 hours with just over 1 hour screen on time. I will leave work in an hour with probably at least 58% left. i NEVER left work with more than 38% with my stock.
Is it a true 320more mAh? Dunno. Do I get better battery life? Absolutely. Worth $21 for 2 batterys and a charger? Most most most definitely.

If you even get the same battery life as OEM for $10 I'd say it's worth it. If it's significantly better that's a great deal.

Anybody else that has bought one care to post their comments here? Are they worth it in your opinion?

If nobody else has dencided to take up the challange I will, I am going to charge both batteries to full charge, turn the phone on full brightness, Wifi on, and leave a program running (a graphics test ot somthing) and see how both batteries fair.
the only time I can do this mind is over the weekend, if someone else has the time to do it beforehand then feel free buti feel that this would a much better way of judging battery life other than 'High usage', 'moderate usage' ect...
I do however feel I got more battery life from the Anker than the stock battery, so I feel the numbers are simply just part of the product ID and people are flapping over nothing.

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?

Also I'm not here to battle myself with others about stats.
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.

battery 3800 not 4000?!

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.

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...

Is OP6 battery really 3300...?

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.
