battery calibration?

hi!
don't know if this is the right forum, but i think i'll give it a try
how can i calibrate the battery of my hd2? or is this not neccessary?
should i always discharge 'till the battery is nearly empty, or is this not a good idea and i should recharge at a certain battery-level the latest?
thanks very much for your help!

im getting v good battery usage and i do thid by full charge full drain 3 or 4 times and i tend to charge when gets to 10% hope this helps g

i think the hd2 general forum would have been more appropriate for this but i guess it won't hurt anyone if you posted here
there are many contrasting views about this and you will probably get confusing answers. i am not an expert but i'll try to brief you with some info i've got from my readings about lithium-ion batteries and my personal experience, of course.
so here we go:

1. discharge fully until the phone shuts down by itself
2. remove battery and wait ~1 minute
3. charge completely with the phone OFF until the green light is lit
4. remove battery and wait ~2 minutes

some recommend to do it every 3 to 6 month
here you'll find many that recommend you to do it after flashing a new radio rom.
from my own experience i tend to agree with this

i've read somewhere that lithium-ion batteries like being charged as often as possible and don't like being left without juice. this is the main reason some people don't want to even hear about the calibration procedure. but i think there is a big difference between complete discharging now-and-then and complete discharging as a habit.
i've never heard anybody recommend a precise low level limit when you should start to recharge.
there is no danger to overcharge though.

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.

No, the battery was measured all the way from 100% to 0%, and that's what came out after several complete cycles. The log is accessible inside the program.

Anker battery 'ageing'. What does it mean?

I am using the Anker 1900mAh battery for last 3 weeks and I am satisfied with the battery life it provides. I did 4-5 charge-discharge cycles and now I regularly get 24hrs - 27hrs life out of it. Today I noticed that BMW Pro is showing battery '14% aging'! What does this mean? Is my battery dying? To confirm I installed the HTC battery widget and it shows nothing abnormal. Please check the screenshots. Is something wrong with my battery?

More than 100 views. Nobody?

My aging says 0%, on stock battery... 5 month old.

I gave up using BMW after getting my sensation, the battery driver by HTC is useless and the statistics the driver gives to BMW can't be trusted.
If you're that concerned then charge to 100%, delete your your battery stats and history and hence start again - but I don't think anything has changed for you, it still guesses your battery as around 1900.

Absolutly right about BMW and Sensation. BMW Useless and confusing only. Don't worry about ageing - continue to use as before.

My phone is not rooted. So I cant delete battery stats. And I get excellent battery life. But the 'aging' thing was worrying me. But after reading your comments not so much worried now. What does 'aging' mean anyway? i.e. in the context of the battery.

Over time and use batteries age... They lose their capacity.... Aging 10% Means that the battery has 10% less capacity than it had when it was new....

I know that is Senasation's driver reporting not correct discharge current, only correct charge current. I meant BMW is useless with Sensation.
And i guess it is not problem of HTC's driver but hardware chipset used in sensation and evo 3d - driver can't read proper values from measurment circuit of chipset. If i would be driver itself, HTC could fix it easely.
---------- Post added at 08:49 AM ---------- Previous post was at 08:38 AM ----------
Don't expect from Anker same quantity of charge-discharge cycles as original battery. It may not work as long as original one(cycles i mean). Nothing can be done with it and nothing can help. They are cheap, so just buy new one when capacity will badly decrease.

Now BMW is showing aging to be 0%. How and why it showed 14% previously I dont know! The battery is hardly 3 weeks old. It cant begin to age so soon, can it? Maybe the earlier value was some wrong reporting. There seems to be a definite problem with the phone's battery driver.

As countless people told you by now - those stats don't mean ****. Stop relying on them. It's useless, confusing information with absolutely no value.
Your battery is fine.

^ What he said. If the developer set the app to say it's 99% aged while your battery still lasted about 25 hours or so.. would you believe that? I'm banking on the assumption that you're not a complete moron and WOULDNT believe that. This is almost the same thing, accrding to all the other users, the app and the battery drivers don't work well together. As everyone else has stated, stop using it? There really is only one way to test your battery properly, and that is to use it. If one day you only got like 15 hours out of your normal 27.. then you know there's a problem. screw the bmw app

You may see what are aged battery here :http://78michel.unblog.fr/htc-desire-battery-shutdown-analysis/ and here :http://78michel.unblog.fr/?p=164
The SoC curve ( state of charge) shows a step during the charging cycle before reaching 100% and a shutdown while discharging. This is very typical.
The aging is in fact the amplitude of the step.....
A precise battery analysis requires a full charging cycle from 0% to 100% with a AC charger.
Your battery is clearly not aged at all..... don't worry

Folks, wiping battery stats is to no use. It only contains the data of what have used the battery since last charge. When you unplug your phone from the charger, the stats are reset. You can't extend or damage the battery life by deleting/altering the battery stats file.

Fast charging

Is fast charging on the S7 ok for the battery or it damages it by time ? I mean i want my phone to hold on for at least 3 years.
Should i disable this option to increase the total battery health ?

With or without fast charging...batterys dont last 3 years.

It may not have dawned on you yet but that battery does not "hold the full charge amount (in mAh) anymore" is in most users mind the very definition of "my f****** battery is gone"!
With the all the pressure on the manufacturers to make the batteries small and the urge to build faster units the usable battery lifespan takes a hit. Even a 20% shorter battery charge time feels frustrating when heavy users may already struggle to make it last a full day with some phones.
So, "way longer than that" (3 years)…? I don’t think so!

So as a conclusion should I DISABLE FAST CHARGING OR NOT?

I have never heard anyone being able to prove fast charging causing shortened battery life. There are a lot of guessing around, but the only difference I have seen is that the phone gets slightly warmer to the touch both after fast charging with cable and wireless. Not so hot so that I would suspect damage. After all, since the charging ends a lot faster the total amount of heat surely isn't higher than that with slow charging. Using the phone will sometimes make it warmer than this.
One could perhaps suspect a higher risk for fire with fast charging, but there is no proof for that either.
The choice is yours!

If you want battery to last longer you do not need to disable anything, instead follow these steps
1. Charge battery to 80 - 85% and not 100%. Stop leaving it overnight.
2. Don't let it fall to 0%, keep it between 20 - 80% charge.
3. Do use phone while charging. You do not want battery heating up.
4. Top up the battery in between your day but keep it within the range above.
5. Keep phone away from to much subglight or warm temperatures. Heat is the biggest enemy of Li-on batteries.

This might have been true many years ago for on old generation of batteries and phones, not for the batteries and smart phones of today. You cannot damage the battery by over charge, there is automatic over charge protection.
You equally cannot do harm to the battery by using it all the way down. There is protection against this also. The system will sense when it is approaching the level that will do any damage at all to the battery and shut down.
No need to worry, just use your phone. There is nothing you can do to make the battery better or worse!

No you are getting it wrong. Don't leave overnight not because it over charges but the fact that you don't want to go upto 100%. Plus everytime you go to 0 battery loses it one cycle. Whatever I say is based on Google research and latest research so it still holds true. For battery longevity never take it to extreme and avoid heating it.

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...
