Hi all!
I was browsing through Samsung Galaxy S's Android Development Section when I saw this:
"11. Do NOT overcharge
--Why, when, where: Almost all new batteries have an overcharging protection. This means that the protection that is built into the battery will not let it charge to 100%. This is a feature, not a bug! This will help prolong your battery life while also keeping it safe from overheating/explosion/etc. Do not try to trick it and unplug and plug again until you see 100%, just get used to the fact that you can't have 100% battery anymore and live with it, or you risk destroying your battery."

I did "calibrate" my battery many times lately by unplugging it when charging and the replugging it. But I sure know I wont do it anymore! It's your choice whether or not you wanna do it!
I just wanted you to know this! Hope I've been helpful!

I didnt say this. I just quoted and I said that I wont charge my phone to 100% with the plug-unplug way. So if you take my advise do so, if you don't want to take it please stop posting ****!

I love this thread already
Isn't calibrating the battery all about fixing an Android bug?
Anyway, this reminds me, the Milestone overstates the full charge mV and underestimates the low battery mV.
So, if Battery Monitor Widget reports that I have 4230mV when it's fully charge and plugged in... it's really only 4170mV.
When it's reporting empty at 3200mV, it's really at 3300mV.
http://www.android-hilfe.de/root-ha...ku-infos-ladekurven-leistungsverbraucher.html
Externally measured or indication of the internal voltage measurement
3.30 volts / 3.20 volts
4.12 volts / 4.18 volts
That is, the stone over-estimated the voltage at the battery is full by ~ 60 mV and underestimated the power of up to 100 mV with an empty battery. The intent is well-battery protection (which is good too). It is pretended that 3.0 and 4.2 volts to discharge until it is loaded. In reality, there are more 3.1 volts and 4.15 volts (which by the way of battery manufacturers also better unanimous opinion!).

Apparently, we are still protected even if we do calibrate the battery.
I'm pretty sure that Payce at android-hilfe actually took that battery out of his phone so I'll go with that.
Thanks for sharing

Gee thank you! I just wanted to start correcting this non-sense. The "overcharging" affects Lithium-Polymer batteries, not Lithium-Ion, so calibrating battery is HARMLESS!!!!
If you have a Samsung Galaxy S then you have this possibility.
I think we can close this thread.
Actually you can overcharge (any) battery, charging it to the higher voltages for higher capacity when used daily (as cell phones).
However it lowers total lifetime of the battery, but you can get more battery time.
But this isn't the cell phones' thing. IMHO charging circuit + circuits in battery won't allow you to do this. So you can't really overcharge.
This "calibrating" is even suggested by notebook manufacturers - you have to do full discharge -> full charge to set the voltage "limits" for 0% and 100%, so the battery indicator can estimate the remaining battery % precisely.
Just few quotations from http://batteryuniversity.com/learn/article/how_to_prolong_lithium_based_batteries to support my opinions:
"In terms of optimal longevity, a charge voltage limit of 3.92V/cell works best but the capacity would be low."
"Should I disconnect my laptop from the power grid when not in use? Under normal circumstances this should not be necessary because once the lithium-ion battery is full, a correctly functioning charger will discontinue the charge and will only engage when the battery voltage drops to a low level."
"Partial discharge on Li-ion is fine; there is no memory and the battery does not need periodic full discharge cycles other than to calibrate the fuel gauge on a smart battery."
The milestone has a Lithium-ion polymer battery which looks like they do suffer from over charging.
"It is important to note that trickle charging is not acceptable for lithium batteries; Li-ion chemistry cannot accept an overcharge without causing damage to the cell, possibly plating out lithium metal and becoming hazardous.[5] Most manufacturers claim a maximum and minimum voltage of 4.23 and 3.0 volts per cell. Taking any cell outside these limits can reduce the cell's capacity and ability to deliver full rated current.
Most dedicated lithium polymer chargers use a charge timer for safety; this cuts the charge after a predefined time (typically 90 minutes)."
http://en.wikipedia.org/wiki/Lithium-ion_polymer_battery
Someone will have to dig deeper into the OEM charger to see if it has some sort of cut off.
the thing with timer seems pretty weird to me. Try charging your battery with very little current - why should you cut it off after 90 minutes? Makes no sense to me, but I'm not an engineer so there may be a fact I overlook.
At the same time with noting overcharge will damage battery cell you should point out that there is no way to overcharge the battery without charging the battery CELLS itselves (not whole battery pack with its circuitry) with your custom charger without monitoring voltage/current.
However - yes, you're right, battery cells can be damaged.
I assume it would be the charging unit itself (i.e. the plug) which as the 90min cut off.
Charging via a USB takes ages (supplied at 5V) and without the "plug" it prob wouldn't have a cut off so the chances of over charging would be higher but would require leaving it in for longer.
I'm not sure, I'm only a first year electriton and haven't touched on batterys.

The "plug" is just 230V~ -> 5V- transformer so the only difference is current, supplied voltage is the same. Btw I leave my phone in cradle for extended periods of time (24h+) and nothing bad happened. When it's at 100% it stops charging so I don't expect anything to happen.
Same with notebooks - it charges to 100% and stops. E.g. HP does stop charging until battery level drops to 90% so it won't "trickle charge" or do many 99%->100% cycles. Dunno how does the phone charging work, because it says 100% all the time. This can be possibly a bad thing
I have always thought that the amperage of a battery made no difference to the voltage due to the factory adjusting the internal resistance of the battery. Amperage I understood was measured in current, however, which does have an effect on overall voltage.
Recall:
V = I * R
With electronics, it is my understanding that the mAh battery doesn't matter as long as the voltage is the same, although you'd get less longevity out of a 1650 mAh vs a 1440 mAh.
Thus, I believe this battery would work. Thoughts? The part number matches exactly what was in my Nexus S and the batteries look identical. If this is the case, save yourself some money buy not searching Nexus S battery and instead searching ab653850ca in eBay instead of paying $30-$40 for a new/replacement Nexus S battery when they are the same thing.
http://cgi.ebay.com/NEW-OEM-SAMSUNG...Accessories&hash=item3a5dd479e2#ht_1287wt_900
Thoughts? Both are 3.7 volts.
mAh is a unit of electric charge, not current (notice the 'h' making it milli-Ampere-hour). So, yes, a lower mAh battery will definitely work, but it will last less time.
Also (just trying to explain better) a battery is not a "powered resistor", so the relationship between its voltage and its current is not just ohm's law (the one you recall). More specifically, the 3.7 volts is due to the chemical reaction inside the battery and is more or less fixed (although it decreases as the battery discharges). The current flowing is basically a function of the load of the battery, so it changes according to what parts of the phone are working at that moment. The output resistance of the battery is a formal way of describing how close the battery is to an ideal voltage source and is not related to the amount of current it's actually providing.
Sorry if I was not clear enough, it's late here!
Missed the h. Not sure why, I see mA all the time and I just missed the h. Interesting and helpful. Thanks man. Clear to me.
That's strange, if it is the same model (AB653850CA), why is it only 1440mAh? But I'm sure it will work.
All I know is that this Samsung Moment battery I got off of Amazon for $6 is almost as good as my stock battery.

The 1440mAh batteries work perfect, I have 2 of them. While you are at it, buy a wall charger to charge them in so they will charge to 100%. Having 2 spares means you will always have a FULLY charged battery to pop in and never have to tether the phone to a charger. Plus you get 2 to 4 extra hours of use.
Very informative!

What do you mean by that ? That the 1440 mAh battery only gives you 2-4 hours ? I doubt it lasts so little time. I hope it doesn't.
No he means charging the batteries in an external charger gives them a more complete charge as I find the same thing. I've got 2 genuine batteries and a third on the way and the external charger charges them to 100% whereas the phone only charges them to around 95%. The batteries charged in the external charger last longer than those charged in the phone.
Hard to know when you're legitimately getting a battery with "more capacity" though, so I just assume I'm always buying another stock battery anyways.

Oh, I got it, thanks !
Anyway, for 6$, I think I'm going to buy one, too. Coupled with the 2nd battery dock, it should work flawlessly.
Hey guys,
I went ahead and ordered one of these too. I noticed that the Watts/hour is 5.55 on the Nexus S battery but on the battery I ordered (but have yet to get in) it says 5.3. Is this going to make a difference outside of how long the battery lasts?
If you guys buy one of these 1440s report back with what you've found out.
And if this is a success, then please urge XDA to sticky this thread or put this on the main page. Paying $50 for a second/replacement Nexus S battery is outrageous, and if this saves my fellow XDA members $45, more people should know about this. :]
UPDATE:
Looks like turbodroid already ordered these and said they work great! Thanks guys! Thank me if this was helpful.
I've been following the great battery impression thread, which discusses ways to tweak the Nexus 4 settings, ROMs, and so forth for maximum run time between charging. This thread focuses on a different battery concern.
The Nexus 4 lithium polymer battery is sealed, and as far as I know, there are still several unknowns about replacing it. We've seen a tear-down showing how to remove the battery. However, as of now, few users have attempted it and there's not a consensus about how easy or difficult it is to do. Questions include:
Even with the correct tools, are the tabs that secure the Nexus 4's back prone to breakage, potentially leaving the case borked?
Is the battery difficult to extricate from its compartment?
Will it a high quality replacement battery become available inexpensively on eBay and elsewhere, or is it this battery, which was not designed to be user-replaceable, too much of an oddball for that to happen meaning that a replacement battery will be expensive and hard to find?
That said, the ease (or lack thereof) of replacing the Nexus 4's battery isn't what I've come here to discuss.
Given the unknowns about battery replacement, my concern is to how to maximize the Nexus 4 battery charge cycles and reduce the capacity drop of the battery over time. It could be bad if after just a year, the Nexus 4's capacity is already noticeably dropping. Not possible? I'm not so sure. Based on what I've read, it may depend upon how we handle charging.
This article at "Battery University" discusses the discharge characteristics of Lithium batteries, and it is my understanding that Lithium Polymer batteries, like the one in the Nexus 4 mirror these characteristics.
My takeaway from the article is:
Charging the Nexus 4 battery before it drops to less than 50% capacity will greatly increase the number of charge cycles before there's a noticeable capacity drop. Letting the battery nearly completely discharge will greatly reduce the number of charge cycles, and therefore greatly reduce the time before battery replacement will be necessary. (Table 2)
Inductive (wireless) charging, while convenient, generates extra heat that will over time reduce the recoverable capacity of the battery. (Table 3)
Having read this article, I am curious about the charging characteristics of the Nexus 4 and which, if any, charging variables we can control as users to maximize battery longevity.
When I first get a new smartphone I try to do a handful of full cycle charges before doing any partial charges. Your battery is still "new" and in the "break in" period. Many users that were the first to get theirs have reported their battery life as getting better. Of course a lot to do with battery are things like your data usage and what you have syncing.

Thanks, but I will again clarify that that I created this thread to discuss maximizing the Nexus 4 battery's long-term life and recoverable capacity, not maximizing run-down time in the short-term. That is already being discussed extensively in the great battery impression thread.
I have had a lot of experience with LiIon batteries over the years and I can tell you that the enemy of them is both inactivity and deep discharge use.
Use your phone as you normally would, but avoid frequent deep discharges. Don't be afraid about the number of charge cycles. Frequent charges are better than deep discharge cycles.
These pups have been designed to be used the way most folks use frequently used rechargeable devices. Pop it on the charger when you can, even if you know it won't be there long enough to be topped off. The more frequent and varied activity the better.
I'll add that I do not currently see an LG BL-T5 Nexus 4 replacement battery sold anywhere.
FYI - The Nexus 4 uses an 800 cycle battery as well so makes it even less of a thing to worry about. My SGS2 still gives me good battery life and it's more than 1yr old already, and i think that is a 300 cycle battery. Remember also that at that 800 cycle mark the battery should still have 80% of it's original capacity. 800 cycles is more than 2yrs of constant use/charge every night and for people that don't so much that could put you in the 3yr-4yr range. If you still have this phone 4yrs from now, i think you wont need to complain if it "only" has 80% of it's original charge.

There is little point in worrying about charging before it's discharged to 50% and/or not charging to maximum. Yes it increases the number of cycles, but is reducing runtime between those cycles, so you have to charge it twice as often using up the extra cycles gained, so overall it tends to even out.
The longevity argument for only partial discharges really only applies at the time of design and specification where the manufacturer can spec a larger battery and sacrifice some of the capacity (by only charging say from 30 to 70%) to get extra charge cycles. Clearly with a mobile phone this isn't desirable to do, as we crave all the the runtime we can get in the smallest form factor possible.

Is the "800 cycle" rating is based on real world usage, or a set of idealized laboratory conditions that few users will actually meet? Many Nexus 4 forum users are reporting running down their batteries to a discharge depth exceeding 90% on a daily basis before recharging. This will dramatically reduce their battery's number of charge cycles. The "800 cycle" rating is only useful if we know the conditions upon which it was tested.

Point taken, although it looks to me like the relationship between discharge depth and maximum number of charge cycles is not linear. From the way I read it, frequent deep discharging can markedly impact battery longevity which is why I'm skeptical of the 800 cycle figure. Given that many Nexus 4 users are currently reporting an inability to make it through a full day without completely draining their battery, those particular users are bound to have shortened battery longevity unless they charge at least twice/day.

Yes it isn't linear, but the advantages are also outweighed by the negatives, such as having to plug it in more often to charge, and if people are struggling to get through the day now on a full charge/discharge cycle.....
The 800 cycle figure is probably about right for chemistry used in the LG Nexus, and most of us will have replaced our phone in a couple of years anyway long before we start to notice the lowered battery life.
The other thing with a lithium batteries is they are like perishable foods, even if we don't use them much, after a few years the capacity has diminished anyway. So even if we only charged the phone twice in two years, the third charge capacity would probably not be that much different to having charged it every day for two years.
So we shouldn't worry about the battery, the best thing we can do is use it as much as possible as it is going to degrade anyway, and we will see little benefit from treating it with kit gloves.
The above also assumes the battery can never be replaced. It certainly is replaceable by the manufacturer or a repair centre, and more than likely most of us could manage a replacement ourselves.

Phil
One very important thing to realize is that these 500/800 or whatever hundred cycles it's talking about is not how many times it can be charged, period.
It's not like after the 500th or 800th charge, this battery can never be powered on again.
Read the article closely:
" the number of discharge/charge cycles Li-ion can deliver at various DoD levels before the battery capacity drops to 70 percent."
Also, if you lower the voltage of the charge, it seems battery long term life greatly increases:
"Most Li-ions are charged to 4.20V/cell and every reduction of 0.10V/cell is said to double cycle life. For example, a lithium-ion cell charged to 4.20V/cell typically delivers 300–500 cycles. If charged to only 4.10V/cell, the life can be prolonged to 600–1,000 cycles; 4.00V/cell should deliver 1,200–2,000 and 3.90V/cell 2,400–4,000 cycles. Table 4 summarizes these results. The values are estimate and depend on the type of li-ion-ion battery."

When a lithium battery is fully discharged, it isn't actually completely discharged. LG like other manufacturers will have programmed a level that shows 0% on the phone before it shuts down, but in reality this might still leave 10% or 20% or 2% capacity in reserve, we don't know the figure, but presumably LG have set both full and empty charge points to ensure we see around 800 cycles.

Yes you get more cycles, but because you have a battery with reduced capacity, you are having to charge it more. Overall the benefit isn't as great as the numbers make it. If LG wanted to give us 1600 cycles they could lower the charge voltages, but then the battery capacity would have to be advertised at around 1050mAh, meaning it lasts half the time it does now, and will need charging around twice as often.
For a mobile phone with a typical 2 year life span, the priority is to maximum the time between charges while ensuring the battery lasts the typical 2 years of most peoples phone contracts. It isn't a co-incidence that 800 charges works out as a bit over 2 years if you charge every day.
We don't need to worry about the battery, just enjoy using the phone. Also the battery doesn't just stop working at 800 cycles either, it just doesn't hold as much charge, but capacity is lost anyway over time regardless if you use it or not as lithium batteries start to age the moment they are made.

A lot of assumptions there, Phil.
My "priorities" and LG's differ. 2 years from now, some will replace their Nexus 4 with whatever shiny new phone comes along that offers holographic video projection chat and does double duty as a sex robot. However, I will happily trudge on with my Nexus 4 for between 3 to 5 years which is how long I typically own a phone before replacement. I don't need bleeding edge, especially if the bleeding edge is a menstruating sex robot phone. Just sayin'.
We don't know if the Nexus 4 battery replacement will turn out to be either very costly and/or difficult. For those of us who don't plan to toss our Nexus 4 into a landfill two years from now, it pays to know what measures we can take to prolong battery longevity.

Hmmmm....how did that happen...
I don't know if we will really know how good the battery longevity is in this thing until the device is a year old or more. Lithium polymer technology varies a lot. There have been a lot of advances with this tech in the last few years and some companies claim to have developed manufacturing techniques that allow THOUSANDS of charge before noticeable drops in batty capacity. Other technologies developed include the tech Apple uses and advertised in its MacBook line a few years ago that claimed longer battery life and very fast charging compared to Lithium Ion batteries. It all varies. LG claims to have some special tech baked into this battery that allows it to charge to a higher voltage compared to batteries of similar size, but I don't know how long its life is rated at.

Hi, I recently got a Z3 compact from clove uk. And I haven't seen the 6+ hours of screen on times that other people are reporting. I've had Battery Monitoring Widget on the the phone since the beginning, and while the system files say the battery has 2663mAh of capacity, the app only records me using up to 2300mAh of battery from full to dead.
I'm not worried about the perceived runtimes as I'm in a bad cell service area and I still have the new phone syndrome. But the physical capacity of the battery seems to be lower than stated on my device. Does anyone else use the battery monitoring widget and can report their numbers?

Thanks for checking, for more accurate results, it's best if you could run the phone from 100% to dead once or twice, so the monitor can capture the full range of your battery.

It will take some time though. That battery just won't die :laugh:
To whatever extent you have "new cell syndrome", it's gonna appear as reduced capacity.
First result at +-27% accuracy: 2280 mAh
Charging cycles: 2

If you can get a number with accuracy below 10%, that would be best, cause batteries are usually manufactured to 10% capacity accuracy.
Thank you
Allright - just don't expect to see the final results within the next few hours
It now says:
+-12% accuracy and still 2280mAh
After unplugging the charger it's: 2253mAh
The value went up to 2398mAh. Accuracy is still at +-12%.

Ok, thanks
Mime says 2440mAh with accuracy at +-5%.
What kind of screen on time are you seeing?
If I remember correctly I had a maximum of ~7 hrs screentime. I did some benchmarking and stuff like that so I'm pretty satisfied with battery life.
Hello all,
I got my self a Find X3 Pro a few months ago and I noticed that Accu Battery Pro and Aida 64 Battery, never reach the min capacity of 4400mah or typical capacity of 4500mah
Is this thing a issue ? Or my battery is degraded from brand new ? Or is this a software incorrect reporting issue ?
Thanks in advance !
Make sure to let it charge for about 7 minutes after it reaches 100%. The phone is not actually fully charged when it reads 100.
See here, after the first charging graph
Oppo Find X3 Pro review
The Oppo Find X3 Pro employs a similar display to the one we enjoyed on the Find X2 Pro. It's a 6.7" LPTO AMOLED screen of 3,216 x 1,440 px resolution or...

Then check again the meters. If they still read 4200, then you may have a degraded battery.
Also, consider that even if the phone is "new", it may have been produced a long time ago (like a year ago or more), thus suffering from some battery degradation already.
I always make sure I let it charge for about 10 more minutes at 100%. Still between 4000mah - 4200mah it displays.
Recently I replaced the battery for an old Mi 5s Plus and after a few charges (3-4) it will show the correct mah of 3800 (~3792mah)
So, did someone actually have these apps display the correct rating of the battery ?
I will give it a try tomorrow, but my phone is 1.5 years old at this point, so I don't expect to see anywhere near 4500 for sure.
I checked mine, but only 2 cycles it showed 89% The phone is 8 months old.
Thank you for your feedback...
My phone is barely 2-3 months old, should I try for warranty ?

Try to charge slowly to 100% using a 3A cable or less and leave it in charge until Aida64 show complete charged, then check charge counter how much mah show. Normally the counter will be a little less respect to declared capacity, like for hard disk the real capacity is not the full declared capacity. My X3 pro is used and charging to 100% show less of 4000 mah but battery life isn't bad.
18 months old phone, about 84% health (only one measurement though)

I'm sorry to tell you but you are mistaken, my ex Red Magic 3 phone indicated my rated capacity for battery and my recently replaced battery for Mi 5s Plus also indicated 3792 mah out of 3800mah, so I presume the issue comes for a incorrectly stored phone when I purchased it or old batch.
I always charge slow or at 1.8A because I'm never in a hurry, I even charged it at 500mah overnight and it went to just 4115 mah out of min 4400mah

No it depend from device to device and also from update cause it change also with kernel version. When I have OnePlus 7 pro always charged slowly bu never reached the full capacity of charger counter, this changed when I tried Oxygen OS 12 India beta, the battery show 4500 in charge counter exactly like the battery capacity. So it can depend from many factors and isn't simply to understand how really battery life is.
Thank you for all of your support and answers !
Yesterday I installed Battery Guru 2.0 and seems a more decent app than AccuBattery, will keep monitoring
AccuBattery and Battery Guru 2.0 tell me that I only have 1598mAh.
Aida64 tell me 3504mAh.
I don't understand...
I only know that my battery life is poor. I arrive with 20% or less at 8:00pm.
It is also true that I have many IOT applications always active, as well for the smartwatch, wifi, BT and GPS always on and also Always On Display all the day.
Cheers.

DO not forget to check the dual cells in the settings of the apps (accu battery and battery guru)
But even so.... 1600 mah x2 => ~3200mah
Very very unusual for this phone and battery
