After 4 years of usage - how to determine real battery capacity/health? - Galaxy Note II Q&A, Help & Troubleshooting

Hey guys,
i've had the note 2 since nov. 2012 and am still on the original samsung battery that came with the phone. Lithium Ion batteries degrade over their lifetime and i wonder how much mine has ''hamoraged'' and whether a new battery would significantly increase my battery life/on time. I've had one battery app installed from the playstore that (i forgot which one) showed a bit above mha 3100 when fully charged. Can this really be true? This would mean no degradation at all, right?
So, is max mha the best determaning indicator of battery health, or can it still show this high a value but drain power much faster than on a fresh battery?
The note 2 luckily has a changeable battery but i would like to actually determine whether a new one would make a significant difference and not just buy a new one just because mine is 4 years old. How do you guys go about it?

[Q] Toke my HOX apart, need internal HI-CAPACITY battery

Hello All,
I toke my HTC One X apart to replace the internal battery with a higher capacity one, as i've tried all the methods listed here to enhance my battery life, but it failed to survive a 12 hours idling - it seems that HTC forgot that the user might use his phone through the day -
anyway, i'm looking for an "INTERNAL" and "HIGHER-CAPACITY" like 2100mAh, 2400mAh battery to replace my 1800 mAh one, any suggestions please?
I don't believe that there is a higher capacity internal battery for the HOX. From what I've read on here is that any higher capacity battery would require the a bigger case for it. Just by opening it up you have now voided your warranty, and any third party manufacturer would not make you void your warranty to increase battery capacity. Your only option is to buy the cases that utilize the pogo pins to increase your battery
thanks for your reply teky, actually i dont care about the warranty, but i believe i can find a higher capacity battery as the iPhone one, i've bought a 2300 mAh from ebay for my old iphone and it was at the same size as its original one, the performance was amazing, it lasted about 2 days with a heavy usage.

likeliness is, if it wasn't physically bigger, then the mah was no more than the original. probably the fact that the first battery was knackered and just buying a new one seemed like it was lasting longer, when in fact it wasn't lasting any longer than a new original battery..
btw, the battery in the 1x is soft...gg, how were u planning on replacing it.

i need too an hi-capacity battery, but...is simply to remove the internal battery?
Be careful... A design flaw in the custom battery may cause it to explode.
Every battery I've read about online that promised higher capacity for the same size proved to be a fraud. The best story I saw was posted on the xda-dev forums. The user cut off the outer packaging of the battery to reveal the original battery inside, and printed on this was the real (much lower) capacity.
I don't know much about battery tech :silly:, as I'm about to prove but ... I believe it's basically a chemical reaction that releases power (and the reaction is revered when charging). The capacity of the battery is related to the volume of material available for the reaction, so basically physics is against us on this one.
If it seems too good to be true, it is. If technology were available to produce safe, cheap batteries, of the same size with a higher capacity, why doesn't a single large reputable manufacturer produce what would obviously be a lucrative accessory?
Are we not missing the point that his phone can't do 12 hours idling? My wife's currently very under used one x has managed 7 days and 10 hours from a single charge with 3g on almost zero screen on so true idle.
My used one x can easily make 2days of what I class as moderate use.
There must be some software issue or as Vodafone in Perth did a misconfigured network stopping 3g from going idle and sucking the battery dry.
Cheers
Steve
you can use the battery of the hox+ and get an extra 300mAh ...
but am going to take the batt of my spare one x and see if the battery of the htc butterfly s would fit... you get like an extra 1200mAh
hope it does....

Please make a thread about that, even if it doesn't fit. Battery life on my HOX is crippling, hardly get 2 hours screen time.

How to manage two batteries?

I've used my Galaxy Nexus for six months without using a secondary battery. At first I bought the extended battery with extended battery cover, but not only did that make my phone too 'thick', it also seemed that Galaxy Nexus is unable to know which battery is being used, so the battery life seemed incorrect when using the extended battery.
I think this has something to do with the battery info memory that the phone stores.
So I ended up buying a second battery, a replacement battery that is exactly the same as the one I originally have in my Nexus.
But since batteries are still different and are bound to perform differently, I wonder how to manage it correctly? Do I always have to drain the phone completely empty before switching batteries and charging the battery with a separate charging dock? I am worried that the phone considers performance of my battery A as the same as battery B, thus in time ending up with lesser battery life on both due to the confusion.
Are there any tips I should know? I need to use replacement batteries since at times I'm on an extended trips where I might not have the ability to charge the phone, but need to use the phone one way or another.
Thanks!
Ah..... I bought some batteries from Amazon. Cheap, like 20 bucks. They are charged, in my bag, if I run out of juice, I switch and start charging the other one. I still have a 3rd that I've never had to use. Hell I hardly use the 2nd one.
All the other stuff you mentioned, I guess I just don't care about all that. I just know they can hold a charge for quite a while. And that helps me when I need it.

These are Li-ion batteries.. DO NOT DRAIN THEM ALL THE WAY DOWN!
**This shortens the life of the battery**
It is better to charge them whenever you feel like it - these batteries and really almost all phone / laptop batteries these days prefers to be charged in shorter cycles and they also do not need to be charged all the way either - IE lithium ion batteries do not have a memory and do not need to be drained and charged fully.
These ideas come for the ancient Ni-Cad batteries famous in AA rechargeable and cordless phone and really old phones / laptops..
Chances are if your device is less than 5 years old it has Li-Ion batteries and the old school thought will actually shorten the battery life
Battery life meaning the amount of power it holds and the number of charge cycles...

You CAN drain them down, as much as the phone allows you. Only deep discharge will harm/kill them.

You cannot drain battery completely empty with a phone. Phone itself will not allow that to happen. Well, it is technically possible, but you need to do a lot more than just drain it until phone shuts down to make it happen.
My problem is that the phone stores information about battery. But if I use two different batteries (despite being the same type and capacity), during battery switches it will not know the battery life of the second battery and can be wrong (as it guesses it based on first battery). People usually delete batterystats file to reset this information, but that sounds pointless to do after every battery switch.
I guess I'll just discharge one battery to about 50% and then store it for just-in-case purposes.

Just a quick link to help out, if you want more info you'll have to Google it yourself
You can use 2 different size batteries without decreasing their usable life per charge.

Another Gold 3500 battery review...slightly scientific

Wanting more battery life and having reading a few positive reviews about the Gold 3500, I got one from Amazon (UK). The numbers 3500 vs 2500 mah indicate I should get around 40% extra battery life compared to stock but having played with RC cars and helicopters running LiPo packs I know that pack ratings aren't everything.
Actual battery capacity depends on the discharge rate, the more juice you pull the less the effective battery capacity you get with a lot of energy wasted in heat due to internal battery resistance. Fact of life with batteries of all chemistry.
My original battery is about 6 months old now, charged daily from anywhere between 0-50% remaining. In day to day use the Gold does seem to last longer based on my 6 months experience with the original battery but how much better is it?
I charged the batteries in my phone and turned the phone off once it hit 100% but kept the charger on as it seemed to charge for a bit longer.
Using my RC battery charger, I used the discharge function setting the low voltage cut off to 3V (standard for lithium batteries) and set the discharge rate at a constant 300 mah. Using a constant discharge rate may not be realistic but it does allow for a fair comparison, keep in mind that our phones power usage jumps up and down depending on use.
Results
-----------
6 month old stock battery rated at 2500 mah = 2364 mah (which is what I would expect from a battery with 180 cycles on it)
Brand new Gold 3500 rated at 3500 mah = 2524 mah (a bit disappointing but at least as good as a new stock battery)
Now the discharge rate can make a big difference to effective battery capacity, it might be that the 3500 mah rating on the Gold batteries was determined using a very low discharge rate or they discharged it to below 3V.....or its just a gold wrapper over a stock battery
Interesting to note that the stock Sammy battery is pretty true to its rated capacity, so the perceived increase in battery capacity I experienced with the Gold battery is probably just the difference between a 6 month old battery and a new one.
Oh well, at least I have a spare battery now and didn't pay a fortune for the Gold. The Gold does seem to last a bit longer than the 6 month old stock on so I am happy enough with it.
Notes:
Gold battery had been in use for 2 weeks to run it in
Only one discharge cycle was performed
Could be that I have a dud battery, you results may differ
In real day to day use the discharge properties of the Gold may result in a higher 'effective' capacity
Solar flares are the source of all coding errors
Fairies do live at the end of your garden :cyclops:
It's a shame i've read this post only two days after buying me one of those. Anyway, even if it won't last longer, i'd still have a spare battery right? So everything is not lost
nope, its a shame they rate it 3500mah if this is the case for all.
Mignon, maybe your can get a replacement from thrm and test again. Especially if you have a dud.
Do notice I notoce a significant increase in battery life after charging it past 100%. Probably placebo, I dont know.
Don't think I have a dud, in my experience lion batteries either work or don't. It's not a crap battery, it's just as good as stock but doesn't match the advertised 3500 mah rating.
And it's shiny gold so things aren't that bad

Well that sucks.....haha...i order a gold a week ago.....it should be here soon.....
I got 3500mah gold battery. I review it.
My rom is ultimate rom v5.1, and my stock battery was 11 months old.
Screen on time was always less than 4 hours.
Yesterday I got the gold battery, and I used it up to 1% without first charge, then I charged it 12 hours to initilize the battery.
So unpluged the charge, and tested it as the same usage. I always downclocked to 1000MHz, wifi on, no use 3g data, brightness is zero, bluetooth and gps is off. I downloaded 15 files and apps today, listened to music, did multi windows function, and almost used web browsing.
Now my battery is just 1%. Screen on time is over 5 and half hours. Obviously the battery was improved.
If official JB are released, the battery will be improved more.
But this is not made in Japan. This is made in China because Japanese is so strange on package.
Some of Chinese battery are so dangerous and may be fake, but this gold battery is good one.

I dropped my stock and it works perfectly till 55% then it dies. Gonna throw it away soon. So some of the cells could be damaged. Its not either they work or dont m8.
@Mingnon thanks for your effortful tests.
@eeynjae, what are all apps spreading around those icons in your notification bar ?
I am pretty sure most mobile 3.7v phone batteries are single cell, only the mugen styled battery extender jobs that require a different back cover run two cells in parallel.
Remaining capacity is usually just a function of cell voltage so it's strange that it should just tank at 55%. Battery protection circuits generally prevent discharge past 3.0 volts so not sure what it's going on there.
Either way it sounds like you need a new battery, wouldn't risk recharging a damaged cell...

yeah its strange. Stuff started to happen at 50, whrn restarting bat percentage dropped to 10-15%. Without restartingbit would go down normally in beginning. Now after using it some time and dropping it its 55%.
Its definitely it either works or doesnt.
Anyway I dont think it's single cell.
i have the same battery bought it a few months back i'am very satisfied....
it's not a 40% extra time even framework it designed to work with less voltage since after using it below 15% i notice always fake meter value, when you keep your phone asleep for half an hour you will notice an increase in percentage. not accurate but runs fine, its a spare and a great replacement i dont care if it's slightly powerful than stock at least its the same size for 4 extra hours.. i never needed to change case nor a cover of anything its great
Sorry for my off-topic question, but i see in this topic there are advised people recently i bought a noname car charger for my Note, (specs: output 5.5V DC, 800mAh) - is this charger good for the Note or it would damage it? (i read somewhere that the original car charger's output is 5V... this difference of 0.5V has any importance?) Thanks.

Thanks for your time and efforts - your results are similar to my amateurish measurements performed twice and reported on the other 3500 battery thread. Having no device to test the actual capacity, I just used the continuous video playback in plane mode with minimal backlight. The time to full discharge was almost identical in both cases.

It won't damage your phone, but if you are going to use it as a gps while charging, it will probably keep dranig the battery, 800mah is not enough to charge it while screen is on and gps is running

Will a new original Samsung battery improve battery life after 2 years?

I've own the SGS3 almost since launch day. Soon it will be 2 years old.
I'm getting 3 hours SOT and 24 hours total.
I'm thinking of buying a new original 2100 battery to see if it improves battery life. Would it?
Anyone has tried this?

I haven't tried it yet since I'm hopefully getting a new phone soon but I do believe it would help, maybe an extra hour SOT because I know my battery was amazing back 2 years ago and now I get the same times you do if not worse.
After a year on mine I was only getting 1700mah, So now I get a new Anker 2200mah battery every 6 months because they are just as good as original but do last longer.
Theoretically yes! battery life should improve, as you will be having a new battery.
My battery is just over a year old and i get around a 1d12h worth of battery time and roughly 3.5 to 4 hours SOT.
I recently bought a Pisen 2100mah battery off the internet and for the same SOT i got more usage. maybe 1d 20h nearing the 2d use.
n.b; wifi is always on. i use 3G for like 30 mins during a day
from what I've heard, newer generations of batteries, like ones that ship with SGS3, should not be drained to 0% with phone shutting down. it was advised to charge at low percents like 1% to 5% while phone is still on

Of course it would and if you dont have problem with size and weight i recomend you to get samsung's 3000mhA battery. Why not getting a bigger battery
It depends how old the battery is though. All Li-ion batteries degrade over time, even if they aren't used. So if you get a 2 year old battery, that has been sitting on a shelf somewhere, it won't help as much as you'd hoped. Depending on the temperature and charge level it was stored at, it could have lost a lot of its capacity.
So the trick is to get a newly manufactured battery, which isn't so easy since most sellers don't write this information.

Since a bigger battery means the battery is thicker,the original back cover wouldn't fit,then you need to use a specific cover which would make your phone heavier.
Right now I am in this trouble,I got a Onite 4500mAh extended battery with a blue cover,hopefully it's a great product, shipping as listed and battery performs exactly as listed,I just don't like the cover,it made my phone looked heavier.I was wondering maybe I should choose a power bank and put back my OEM one on.

This is true. You also need to account for your usage. If you do a lot of activity that heats your battery up (games, navigation, etc.) Then even a shelf stored battery will help since heat is another Li-ion killer.
My S3 was 2 years old in May of this year. I have been having issues with the battery and charging. My USB charging port has the classic loose connection issue as does the headphone jack. I see the fix and YouTube videos to repair but have not yet done that. I last week got my new OEM Samsung battery and the external charging kit. I just upgraded to Kitkat 4.4.2 NDA8 despite being eligible for a new phone discount from Sprint. My S3 is a 32gb unit and I will not buy a S5 with only 16gb, no way no how.
The new battery is performing very well. It is so close on updating to 4.4.2 that I can not be certain that there were not issues with my rooted 4.1.2 build after so many months. For sure the new battery is lasting longer. I think it was worth the $42.03 spent on the charger and battery as my USB port is in question and I can always swap batteries and charge with the external charger.
My S3 has a new lease on life and I can wait for new tech before upgrading. xda developers forum - root - and the desire for liberty is a powerful combination.
why not try using wireless charging? the qi reciever + charger should not cost you mote than 35 bucks. and you can still use your current battery, battery cover, & nfc, unlike powermat.

A 2 year battery will definitely be worn-out. Depending on the charging cycle count, could be only a 20%,but maybe a 50 or 70%.
I bought a Zerolemon 7000mAh battery few months a go, I'm usually getting 4-5 days on normal usage, and 11-13h of screen on.
Best bought I have ever made.

[Q] battery life, what's yours?

Hi guys, I hope this is the right place for my question. I bought my galaxy nexus 1 year and a half ago, actually I installed the Slimkat rom but the battery life seems really poor, for example in this moment I've got 68% left with 1h of screen activity and 4.30h in general.
I don't know what's the average of the gnex battery life, but it would be great to improve it a bit. What's yours?
Can you tell me what rom can give me the best battery life? I'm not sure but I believe to remember that with the stock 4.3 the situation was better (not too much really), is it possible? shouldn't 4.4 be optimized to increase battery life? I've read about people with 4-5 hours of screen activity, how is it possible?
thank you and sorry for my english :fingers-crossed:
Generally, battery life for my 2.5 year old Gnex is generally not good. In fact, it's poor when new, and gotten worse over the 2 years. I'm using CM11 with Fancy R51. I think it helps the standby time significantly, although screen on time still suffers from the aged and small battery.
Recently, I made a pogo dock for it, so that I keep it constantly charged while I'm at my desk. At least it helps to reduce wear and tear on the micro-USB port.
well, I understand that battery life can't be the same of when I bought the phone but I read about people with 4-5 hours of screen activity with stock battery! I found a topic about cataclysm 4.3 rom where users say that it has great battery performance, unfortunately I can't post there because I'm a new user. I wonder if a custom rom is necessary or that's only 4.3 worth. Can I eventually flash that from from mine? Slimkat4.4? thanks
I bought my GNex about a month ago and had the intention to use the biggest battery available.
Battery: Zerolemon 5800mAh
ROM: latest CM11 release
My battery app: Battery Monitor Widget Pro
BMW tells me that the battery is actually about 5100mAh, but this average grows a bit with each full charge cycle. The problem is that it takes more than a day to run the battery down and more than a night to get full charge.
With the giant battery I don't worry about managing power.
3h's is the max I've ever got, but normally I only get 2h's.
Only way I ever see our GN would getting 4-5h's of ON screen time is perhaps if the brightness is set to the lowest level, using Wi-Fi only for data AND doing something that require very little CPU power (ie. not gaming/video).
Same. Never got more than 3h of SOT with the stock battery. Let it be Android 4.3 or 4.4 rom. I've tried a new OEM battery as well. The only option to get better battery life is to use extended batteries.
Giant battery with NFC!

BMW tells me that the battery is actually about 5100mAh, but this average grows a bit with each full charge cycle. The problem is that it takes more than a day to run the battery down and more than a night to get full charge.
With the giant battery I don't worry about managing power.

Zerolemon looks great! Pity zerolemon doesn't have it for the GSM version. Does the purported NFC work?

NFC is wireless charging?
I only have a standard charger. Maybe some reviews of the battery on Amazon would be a good source for your answer. Sorry.
thanks everybody for the answers, it's a pity because my gnex still has great performance but I leave you imagine what happens when I turn on GPS . For those who talk about extended battery, can you suggest me a model? I read something about non-original battery and possibility of accident, what do you think? thanks

No, NFC isn't wireless charging. It's Near Field Communcation. The gnex is NFC-capable, but the antenna for the NFC is embedded with the stock battery. Upgrading to third-party battery usually disables the NFC functionality. Well, if you don't use it, you're not going to miss it.
Hmm, I will look into that. I don't know if I use it or not. I'm still learning about the phone, but very happy so far. Thanks for the clarification!

Ok, read up on NFC on Wikipedia and no, I have not yet used it.
However, one of the top rated "helpful" reviews of the zero lemon battery does mention that NFC does work. I am not currently in a situation that allows me to confirm it. Maybe someday soon.
