So i have the battery monitor widget app, and it shows that calibrated capacity is around 2600 mAh, so this means the battery has degraded, right?
I have been searching for original batteries, but on AliExp**** there seem to be only batteries from around 2014, and some people say the battery swells after use etc., so i'm hesitant to buy from there. Any other sites maybe?
the test is not so accurate.
i would stick to this battery untill you feel the battery life is horrable.
you can but a new battery for about 17$.

From http://www.wmskins.com/blog/how-to-increase-battery-life-of-windows-mobiles:
1. A Lithium Ion battery should never be charged to 100% or fully Discharged. The famous 80-20 rule is applicable here as well, though in a different way. Charging to 80% increases battery life.
2. Don’t wait for full discharge, charge it frequently. Keeping the battery near to 80% always, gives better life. This is also what many vendors claim as “memory effect”.
I followed that advice and then after a few weeks, when once I charged it to 100%, it dropped quickly to 80%! and has been like that since. now I don't give a damn to that rule and charge my phone to 100% instead.
At this point, I would advise you do a full charge and deep discharge of your phone. Just to allow the phone to calibrate itself to the battery again.
However, I would advise against running programs to intentionally drain it at a high draw. So instead of playing 5 hours of FPSECE to drain it flat, just let it sit on standby and use it as you normally would, until it dies. Then charge it back up in one continuous charge (refrain from unplugging until it goes back to 100%). Hopefully that will restore the accuracy of your battery meter by a bit.
And IMHO, the article you included discusses things about batteries that are no longer true....
2. Don’t wait for full discharge, charge it frequently. Keeping the battery near to 80% always, gives better life. This is also what many vendors claim as “memory effect”.
No. "Memory effect" is, in laymen terms, the battery not being able to hold above a certain charge after being repeatedly discharged from the same capacity. E.g. being discharged at 80%. It doesn't "give battery life" -- in fact it kills your battery's capacity.
This is a term more relevant for old NiCd batteries. LiONs and most NiMH batteries have very weak/no memory effect.
3. Every battery has limited Full charge-discharge cycles. Of the order of 300+. In other words a typical phone battery can be fully charged/discharged 300 times. Doing more frequent charges, as specified in point #2, will increase overall life.
Partially true. Every battery can be charged a number of times before its ability to hold a charge deteriorates. Usually this is around 300, though the exact number varies between individual batteries. However, the concept of a "cycle" isn't exact -- just because you charged from 60-80% (or whatever) doesn't mean you didn't use a cycle. It's really a continuum, and should only be conceptualized as the battery losing its ability to be charged and hold a charge, the more times you charge it.
4. During first time use (when the battery is new) don`t use it till its fully charged. This is why it is always written on manuals “let the device charge for 2-3 hours”.
The necessity of preconditioning is controversial now. There is little evidence to suggest that devices nowadays benefit from preconditioning, and likewise there is little evidence that not doing so harms battery longevity. Many manuals these days simply omit to mention preconditioning.
5. Best way to increase battery life is Not to use it. If you keep AC power plugged in on your phones, keeping the battery at 80% (as in #1), your battery will last longer. Though discharging it once in a month would be must in such cases.
Partially true. Not using your battery does indeed help its longevity, but not by plugging into the AC. Heat is a LiON battery's enemy, and plugging it into your wall will generate heat that is ultimately bad. This translates to laptop batteries as well -- if you want to store a laptop battery, the best bet is to discharge it to 40%, then put it somewhere cool (even the fridge if you want).
Also I would say doing a deep discharge once a month is too frequent. Once every 2 or even 3 months is more appropriate.
Finally, LiON batteries themselves have a shelf life. So even if you let them sit there, they will lose their function after a few years. Just so yo uknow.
6. Surrounding temperature contributes a lot. Colder weather gives better battery life. So make sure your cellphone doesn’t overheat, if it does, find ways to keep it cool.
True. And that's why you shouldn't leave it plugged in.

is that so? why? so i guess now my battery's capacity has lessened. damn the article.
have drained my battery to 1% and charged it to 100%. let's see how it goes from here..
good subject for discusion. WM user or not the battery life and the tricks of LION only a few knows.
1.i have two batteries for my HTC. he original battery and one with 2800mAh. Does my phone cofused if i change tha batteries aternately?
2. if ai want to work with my phone for hours is it better to connect it with the charger?
3. Wich kind of charging is better? with USB cable from pc or wall charger.
I have the option in my BIOS for my laptop which says an 80% charge will prolong the lifespan of the battery.
Batteries must undergo a fair bit of research (for environmental impact reasons if nothing else!) and to have such a bold statement to me indicates that its an obvious fact to battery researchers.
Given ive lay in bed this morning messing about on facebook and setting up rss feeds on my phone and emptied a full battery I dont think Id ever stop charging at 80%. Ill just buy another battery!
i really doubt cold weather improves battery life, numerous times my family and I brought electronic products to cold countries and the Battery life always drops at a much quicker rate

You are taking what i said out of context.
What I'm saying is that IF your battery had a memory effect as the original article claimed, then charging the battery to only 80 will create a memory at 80, which would be worse for your battery. I'm merely trying to point out an inconsistency in there article.
However, I went on to say that li ON batteries do not have a memory effect. So more relevant to the real world is the fact that our batteries will not experience memory as claimed by the article.
Two main things kill lithium batteries, heat and time as they promote deposits forming in the electrolyte, which reduces the capacity of the battery.
So, buying a "spare" battery at the time you buy a phone with a plan on using it when the original battery starts to fail is a bad idea as the spare battery would be slowly deterorating on the shelf.
Deep charges rather than top up charges are bad as they produce more heat inside the battery, although doing it if your battery doesn't seem to be holding it's chage is a good idea as it should recalibrate the phone's battery level software.
To paraphrase the old saying, " blogs and opinions are like a##holes, everyone has one "
I have followed the links in this thread and so far I have just read unsubstantiated opinion.
I have used " cordless " electronics for most of my life and have used all kinds of batteries extensively as well as talked to company reps and battery " experts ".
Nickel Cadmium batteries had memories. The batteries had to be conditioned and fully charged and discharged. The new Lithium Ion batteries were advantageous , not only because they held a bigger charge and lasted longer, but also because they have NO memory. The latest example being, I regularly charged my Tilt battery to all levels of charge. Mostly 100% everyday and ran it down to 5% most times before charging it again. I used it a lot and charged it a lot. and it lasted 2 yrs.
The only difference I have really noticed in batteries has nothing to do with the way you charge it. It has to do with " getting what you pay for " I have had quality batteries really show their quality and $ 12 batteries give me up to and only my $12 worth.

I have a Nissan Leaf. It is clear that the engineers have spent a LOT of time thinking about how to maximize the life of the battery in the car. One of the options the car come with is to ALWAYS charge the batteries to 80%. In fact, they've gone as far as to add a button on the dashboard to override that setting in cases where a 100% charge is needed. According to the documentation that comes with the car, this is the single most important step to prolonging battery life. Next is frequent charges. Next is monitoring battery temperature which is constantly shown in a BIG display on the dashboard. In general, a good way to think about a lithium ion battery is that over its life you're trying to maximize the amount of power stored and then subsequently removed from the device. From the research I've done, if the "charging/discharging life" of the battery were cycles that swung from 100% to 0% you might get X kwHrs of power "moved" through the battery, yet if you were to limit charges to 80% and constantly charge it after each use, you could expect at least 2X! So it's a big deal. I live in Bellevue, Washington which has a very mild climate and have put 26,000 miles on this car in the last 2 years, making mostly small 3-to-20 mile trips, and I routinely charge the car when I pull into the garage, and would estimate that the battery has been charged well over 1000 times. To date, there is no detectable loss in battery capacity; the first indication of which would appear on the car's instrumentation when just over 4% of the charging capacity of the car has been lost.
My Sony VAIO Pro 13 actually offers the 80/20 option in Power Settings. However, I do not use it.
Are there any larger batteries that will still fit in the stock back. I want an "extended battery", but am not willing to sacrifice my Active X case to get one.
For all intents and purposes, no. There is a 1600 mAh that sells for some ridiculous price like 60 dollars or something, but anyone who spends that much for a 100 mAh bumb at BEST is moronic. Also, Stock batteries typically have an extremely high real life mAh, usually 95-98% of rated mAh. Any aftermarket will not have as high of a percentage, so a 1600 will probably be just barely better than stock.

This is not true the 1600 battery is a seidio and seidio batteries are pretty well known for being higher quality than stock. Tag on some extra charge on top of that and it will probably be quite noticable. A couple years ago when I had a touch pro 2 I bought a seidio battery that had 250 mAH more than stock and in real life usage I almost got double the time out of it. I changed from charging every night to every other night.
That is absolutely based on no truth. Seido is ABSOLUTELY not better than stock. In fact, NOTHING beats stock batteries.
batteryboss.org
No Seido battery has better than an 84% real life mAH to rated mAH. Stock batteries have at MINIMUM 95% real life mAH to rated mAH.
84% of 1600 = 1344 mAH
95% of 1500 = 1425 mAH
I think I am just going to hook a car battery up to it..........it will be months before I have to recharge

muyoso, do you have the research from the site to back up those numbers? I'm not about to go digging for it myself...
There are a variety of factors that reduce a lithium ion battery's performance. First of all, lithium batteries have a higher internal resistance than their nickel metal-hydride and nickel cadmium counterparts (counterparts in the sense of their use in cell phones over the years). This is one reason why they heat up quite a bit during both charge and discharge, and consequently "age" faster when existing in a warm environment.
Lithium batteries self-discharge at around 8% per month, and during this time typically suffer a permanent capacity loss when left unused. Batteries that were produced and stored in a warm place for too long will certainly not charge to as high of a capacity as another identical battery that was produced and began earlier discharge cycles in a real-world environment.
Lithium batteries do not have a "memory," which is the effect that nickel cadmium batteries are reputable for carrying over the course of many charge/discharge cycles. In other words, your battery isn't going to suffer because you never let it run dead before charging it all the way back up. It doesn't matter. However, leaving it on a charger with Wi-Fi, Bluetooth, and a high-definition porno on simultaneously will only negatively effect the battery due to the heat generated from current delivery.
Some batteries are simply better than others. This holds true even among batteries of the same brand, capacity and application. The way they are handled, stored and used determines the life and performance of the battery in your phone. In this case, do not drain your battery to 0% before charging it back up. It's typical for lithium batteries' capacity to permanently drop by 15-25% within one year's use.
If you have a spare cell, charge it to about 40%, take it out and put in the refrigerator. Also, make sure you check the manufacturing date on the packaging, as I said before, storing for long periods without a 40% charge or regular charge/discharge cycles will result in a lessened capacity.
Just figured I would throw a few facts out there. I began using lithium batteries for robotics projects a number of years ago when they became much more prevalent.
The guy behind batteryboss.org did extensive testing. Stock batteries were all rated at near rated capacity. Seido batteries were not. He clearly explains his testing procedures. I have read over that site pretty thoroughly and trust his numbers and technique.
hello,
i replaced the original battery 1500 mah with 1900mah battery by ebay. but the capacitiy of the new one shows 1500 mah wich will not be true.
so what to do in order to show the 1900 mah.
thx
Your phone cant show battery capacity, maybe you are using some software that shows standard capacity (because it was written to show that).
oh realy? its not possible to display the real capacitiy after replacing in different batteries in differen mAh?
hence i cannot determine the capacitiy of the battery, i must blind trust what written on the battery?
thx
U have to mesure it more professionally or your software is good and your battery is really a 1500mah. But most of all - check it in real life usage and compare.
Hello guys, searching the net for higher capacity batteries i've found this http://www.aliexpress.com/item/free-shipping-for-BLUE-2830MAH-HIGH-CAPACITY-REPLACEMENT-BATTERY-FOR-LG-E960-E975-brand-battery/1303576275.html .
Did anyone found something like this, but from normal famous manufacturer? Two years ago I bought for my Galaxy S a PolarCell battery with higher capacity, which really lasts longer as the original and was only one or half mm thicker. Why the hell there no such batteries for our N4 or I'm not searching good enough?
There is no bigger battery with same size.
Maybe typo error, but at the description it says that battery is 1980 mah.

Sorry posted in wrong thread. Please delete.
good find :good:
Assuming 80% battery charging efficiency in this and the phone, 36% of energy is lost in charging this battery to charge a phone battery, vs 20% by directly charging it. So, given it's not in a phone case form factor, the only people using this will be ones where there is no power.
I'm hoping some with battery monitoring app can shed some light on this. I get decent battery life, comparatively to what I'm reading on forums. In CPU-Z my battery is rated as "GOOD" which I'm assuming/hoping is the highest rating as my phone is only 1.5 months old. Out of curiosity I decided to try the AccuBattery app. The first test charge of 7% (my phone was at 93%), above the AccuBattery minimum of 5%, said that my estimated battery capacity was only 2450 mAh. It was correctly reporting the design capacity of 2700 mAh. I'm going to let the battery discharge more this time and try again... 9% wear seems impossible. Thoughts...including is there a recommended app that gives reliable battery wear/capacity data? 2-year old Dell laptop still only reports 2% wear.
It may be the software, including needing several charges to provide accurate data. (maybe). I just did a charge from 75% to 100% on a HTC One M8 with 2600 mAh battery and the results were almost the same (2400 mAh estimated true capacity).
