Greetings to all! I have bought a battery big capacities, 3200mAh. But phone distinguishes it as old, 1,5mah. And after 40 percent of gymnastics sharply jumps for 100 percent, and does not charge further. As it is possible to make battery calibration in phone that it worked on all 3200mah

Hi all,
I bought a new battery for my HD2 which has 3.400 mAh. Unfortunately the HD2 does not seem to notice the higher capacity.
Battery.exe from htc testing tools shows "FULL (mAh): 12296". As all values are times 10 (like 786% battery right now) I read this as 1230 mAh battery capacity the device thinks to have.
How would I recalibrate the device so it recognizes the new battery capacity?
Thank you, Franky
P.S. I tried to search but found nothing I had'nt already tried. Most people suggest something like this:
1. discharge fully until the phone shuts down by itself
2. remove battery and wait ~1 minute
repeat 1) and 2) until the device shuts off within minutes after being switched on
3. charge completely with the phone OFF until the green light is lit
4. remove battery and wait ~2 minutes
which I tried at least 5 times. I even bought an external charger so the battery is 100% full when put into the device.
Is it a genuine battery, bought from a reputable dealer? I bought a ' genuine' battery from an Amazon seller which was a bad fake, got very hot and only have half the capacity it should have.
If you are using battery in WinMo then I thought there was little to do, in Android there are several tricks but essentially charging with the phone off should give you a full charge.
Have you tried using the phone until it switches off? It might be that you have the extra life but your software doesn't recognize it.
Thanks for your reply!

Dunno. All dealers pretend to be (the only) serios. But it's a German dealer /w good ebay ratings.

That's the issue. When the phone shuts down (unfortunately it does that silently, not like a Nokia) and I remove the battery (wait some time) and re-insert it it is at 50% and lasts a few hours more (BTW: doesn't work a 3rd time).
How to tell the software/phone it got a better battery?
BTW: It's WinMo 6.5.5
Thanks, Franky
The phone should only shut down when the battery reaches a certain voltage, or the battery shuts itself off to protect the cell. It sounds like your phone is working properly by turning off due to low voltage, but then when the voltage rises (when you rest it) restarting. The battery protector circuit would not allow it to start for a second time.
You can try using battclock to check your voltage, which should be 4.206 when fully charged and down to around 3.2 or 3.6 when empty. But I think you have a fake battery that simply will not contain that much power - it is a double thickness one, with a bulging battery cover required?
Hi boomboomer,
private talk, he?
Yeah, the battery is a double thick one with extra cover.
Battery.exe showed these values when I got 1% battery left:
MS percentage: 1%
PA percentage: 1%
ACR (mAh): 83 (i.e. 8 mAh)
1st dis_ percentage: 150%
V_MBAT (V): 3.742
after removing the battery and setting it in again after 5 minutes I got these values:
MS percentage: 47%
PA percentage: 47%
ACR (mAh): 5776 (i.e. 578 mAh)
1st dis_ percentage: 470%
V_MBAT (V): 3.747

If you notice the voltage reading stays the same for both instances, 3.742 V which isn't far off shut down value for the phone. What is changing is the current value, which if the voltage is constant means the battery resistance is dropping after you rest the battery for 5 mins, or letting the cell cool down and hence giving the impression that the cell still has 47% capacity - which it does not.
A high internal cell resistance means high temperatures and a very short life span, a genuine battery should have a fairly constant resistance and hence linear discharge.
Bottom line is your ebay seller did not send you a battery capable of providing 3400mAh, it may also not be safe to use in your phone in certain conditions e.g. a hot sunny day on your car dash may result in a breach of the cell membrane and even a lithium fire.
I would advise returning the battery for a refund and spend a little more for a genuine HTC extended battery from someone you trust.
Well, besides that I cannot send it back (it's dearer than to dump it) the battery shurely has more than 1230 mAh. From what I saw its somewhat about 1800 mAh (1230 + 50% battery left when re-inserting).
Only the HD2 does not recognize it.

I know there is already information on this topic ..... I have read conflicting advice on how to charge cell phone batteries, but I want to make sure and get the maximum use and life from the ZeroLemon 10000 Extended Battery for my Note 3 .....
The directions from the company simply state to give six full charges, but there is no explanation exactly what that means. I have sent the company a question regarding this issue, but still have not yet received an answer .....
I just finished the third full charge. When I received the battery, I charged it for 12 hours before unplugging from the charger. Then allowed my Note 3 to go completely dead (to Zero %). Then charged again for 12 hours. Did this three times so far.
I'm only getting around 37 hours of medium to heavy use, or about 1 1/2 days, and around 18-20 hours of Screen On Time, which seems somewhat impressive!
After I go through six charging cycles, should I always charge for 12 hours, or is this no longer necessary?

Based on what I read in charging lithium ion batteries ( which I also practice ), you don't wait until battery discharges to 0 before charging it since it shortens the life span of the battery by damaging the negative electrode. The recommendation is to charge it once it reaches 10% and don't have to fully charge battery to 100%, just around 90 - 95%. Since lithium ion batteries don't have memory effect, partial charges and discharges don't have negative effect on the overall battery life.
Didn't made this up, just quoting from memory.
Never let my stock note 3 battery go below 5 percent. I am getting great battery life. The same with my old i9100.

Galaxy S3 Neo has a ridiculous stock 2100 mAh battery which offers a very poor duration. That's the reason I need an extended one. I have tried lots of extended batteries of different brands such as DSK, Anker, and one that I don't know its brand, I bought it from http://www.tucargadorsolar.com/. All of it have offered me a very poor duration. They are supposed to have twice the capacity of stock battery but here are the results that I got with all of them:
Original 2100 mAh battery, 100% charged, holds for 5:30 hours on continuous video playing until it reaches 5%.
Different extended batteries (4200 to 4400 mAh depending on the brand), 100% charged, hold for 6:45 hours on continuous video playing and in exactly the same conditions of the other test (screen brightness, bluetooth, wifi...).
I have repeated the test lots of times and always get the same results. If an extended battery of 4200 - 4400 mAh has a double capacity and original battery holds for 5:30 hours, why the extended one does not hold for the double, 11 hours?
I suppose that I have been testing batteries coming from not reliable brands.
I ordered a battery from Mugen Power 3 months ago, because it is supposed to be a reliable brand. But 3 months later still know nothing about the order I've made, and now they don't answer my e-mails.
What can I do? Is there another brand which is reliable enough to offer me a good duration?
I am really annoyed with this, I have lost very much money and time and all batteries I buy are in a very bad condition.
Well you could just money to buy another phone Anyway, if you're on stock, I can't say much, but using a custom kernel with governors etc, it would be really a great option as with the default battery, it last way more longer.
It's really strange, really. Have you calibrated the batteries right by reading the manuals? Are you sure about the capacities (Have you tested them with a multimeter)? Have in mind (if you haven't already known that) that I9300 batteries are exactly the same, because it's wide known and there are for sure reliable sources. A phone like Neo, is easily targeted with fake things. Last, you should buy from Amazon and read the reviews. Oh, did you try to contact with the companies?
Again, it's very strange....
S3 neo's battery functionality is a joke...
I try a lots of extended batterys baut only one is in right...Anker 7200mah(buy from amazon)
But s3 neo have a "bug"...completly charge of ectended batery is possible just if you replace battery after first charge to "100%" and put on charge again...aproximately after replace cell, phone was display the true charging %...
After 2x 3x replaces battery was true 100% charged...
Discharging is same way....after first 1-2% level replace the batt....it shows aprox. 70% after....
Replace "trick" is only one way to use extended batterys capacity.
What are your true battery capacity? Has anyone run the full battery charge cycle through mAh meter? My phone was in transit for a whopping 2.5 months. It arrived with 0% battery, fully drained. It charged OK, but battery seemed too weak. I did charge it couple of times, then after a full discharge (to 0%, and shut-off) I charged it to 100% through mAh meter, and it only showed that battery took in 2232 mAh instead of factory capacity of 3100 mAh. I'm afraid that the battery has really degraded while being at 0% in winter cold (mild but sub-zero temperatures here in Canada). Or is it just because it's new and will improve after several cycles? Not sure how accurate is the mAh meter, or whether it's the right way to test. I've also installed AccuBattery, will see what it reports, but I'm not optimistic. With another phone I'd replace the battery, but you need a heat gun to open this one, it's a huge mess with a chance to kill it... So any feedback on your batteries or tests? How can I really verify that the battery is within factory specs?
Drain the battery to 0%, then use a 5v/1a charger to charge the device. Verify with an app that the phone is craging at 5v/1a, then switch off device and measure exactly how long it takes to charge to 100%. Then use this equation
Q(mAh) = 1000 × E(Wh) / V(V)
simple version:
mah = 1000 x (5 x hours charging) / 5
Then we can establish true battery capacity
I have solved this issue. Turns out that with fast charging my USB meter was giving inaccurate results. I used another charger that was not engaging fast charging, then USB meter showed normal capacity, which was almost exactly 3100 mAh stated.

How are you finding the battery life? Can it always get you thought a full day?
Yes. I'm not a very aggressive user. Occasional use gets me to about 40% to 60% by the end of the day. Most people will use phone more.
hi guys, as a heavy user as i am i have 6,5 hours of SOT, so it should be enough for a heavy day use.

i forget to mention im on the AOKP ROM
i bought new battery for v20 (nominaly 3200mah). but i can't confirm really it is 3200mah.
how can i be sure about real capacitance ?
when i install new battery its level was 46%.then i discharged it to 1% and after 95 minutes it charged fully.
