Extended battery longevity practices

I ordered the HTC 2150mAh Li-Polymer extended battery and door from HTCpedia. What tips do you have to ensure that I get the most out of the battery? Is there a particular charging process you go through when you get a new battery? The battery was expensive and I want to make sure I take good care of it.

Why didn't you get it through verizon? They sell it for $59.99 compared to HTCpedia's $79.99

Fully charge, then use. It may take a few cycles before you see optimum battery performance but you don't need to "condition" the battery. Lithium ion batteries do not need to be fully discharged/recharged, in fact if this is done frequently it can hurt the battery.
You can do a google search if you want a more in-depth explanation.

Fully charge battery,then while the phone is still plugged in, power phone off - leaving it plugged in, then you'll notice the LED will turn red again. The phone will charge for about another half hour or so - this will give you a true full charge.
The OS on the phone will think it has a full charge, thus cutting it off before it is fully charged.

I was told they weren't available through Verizon yet. HTCpedia has an awesome return policy, so I think I'll send it back and get it through Verizon. I could really use that extra cash.
Thanks for the tips on everything.

Anyone experiencing issues using the Htc 2150mAh extended battery? My live backgrounds freeze up and i don't get 3g service in areas i usually do.

I don't think that could have anything to do with the battery.

i thought that as well but i didn't start experiencing the issues until i hooked up the new battery.

Just got mine from Verizon today and my company gets 25% off accessories, so it cost me $48 w/tax. I got free overnight shipping by using promo code: freeovernt
Still charging...

After only one full drain and recharge i've had over 21 hours of battery life. i've been using it like crazy for the last 3 hours to drain it again. I think i could easily get a day and half out of this bad boy. Well worth the added bulkiness i might add.

I'm using my stock rom still (havent taken the rom plunge yet, mostly cause I have everything like i want it right now).
I flashed the hydra undervolt/overclock kernel (hydra_ocuv_ov2_n_v07_signed) and have setcpu set at min 128 and max around 800 (i change it to 1000 or so when i need the extra umph and not trying to save battery as much).
Also I have the Verizon 2150 mah extended battery.
Currently with medium usage (both using the internet, barcode scanner, playing a couple songs here and there, send a couple text messages, 1+ hours a day on the phone, playing with the phone on wifi a bit), im getting over 48 hours usage.
Last time on the charger was yesterday morning at 10:30am. Its almost 11 pm and im at 50% right now. I dont have gmail doing an email checks right now at all (i check it manually once in a while), and I only turn on 3g as needed.

new battery

Hi,
I got a new aftermarket battery, same size but more power: is there anything I should do (delete battery stats, manually or through an app, etc...) to have it work properly?
thanks

Nothing special to do.
Problem is, if the battery is the same size, its probably the same (or even less) mAh capacity as stock, and just being sold as larger w/ a different label

in theory battery is without NFC so the advertised 1900mAh should be real
is tehre a way to check the real mAh of a battery?

Battery Monitor Widget shows you the mAh of your battery,
By the way, Did you tray to dial the code *#*#4636#*#* on the phone, and then go to the option "battery info"?

As with any battery I suggest charge and discharge FULLY two or three times to condition the battery. Don't top it off for the first bit. If its not genuine, I wouldn't hold my breath. Don't let it sit discharged in your phone lest it leak. My 2cents.

if its the same size as the oem its not 1900mah.

New battery conditioning

What is the proper way to condition a new battery? I just purchased the Samsung 2100, and want to make sure I use it properly.

Just use it. Lithium batteries do not need to be conditioned or discharged completely or anything like that. Just use and enjoy.

I bought the Anker battery and it says to deplete the battery fully before recharging it back up to 100% without pulling the battery out of the phone...4 times. It may be a bit much but I wanted to make sure I got the most out of the battery. I believe in it because (i bought 2) one doesnt last nearly as long as the other...I properly conditioned one but not the other.

aftermarket batteries need to be condition like, fully drained and fully recharged.
on the other hand oem batteries don't.

Li-ion/Li-polymer batteries do not need to be conditioned. You are only wasting your time, it will make no difference whatsoever to the health of the battery. In fact letting these batteries run down completely can be harmful to them

You could never condition a Li-ion battery but simply calibrating how the OS logs the battery stats.
That's it.

1-You can't condition a li- on battery.
2- If you could, you wouldn't need to condition a manufacturer's battery.
3- fully depleting any battery harms (and could kill) it. That's one reason most devices won't really allow you to drain every bit out of it (cell phones are a prime example)
4- I've had batteries that I 'conditioned' end up weaker than they started out
5- I never stop at #4. 1,2,3,4,5. 1,2,3,4,5. It has to be done 3 or 4 times.... 5 3,4,5 3,4,5 (just kidding)

I agree but why do you think the stock samsung battery would not need this? I mean it does specifically state in the manual to not use until fully charged. I doubt they are just saying that not knowing what they are talking about.
In anycase like almost anyone who buys a nexus I am way to excited to wait for the dam battery to charge.

The charging cycle is only for the firmware to log the battery stats so it's reflected correctly; it has nothing to do with the battery itself. That's why people recommend it for new batteries - OS will be able to reflect the battery level more accurately.
Like it's been repeated gazillion times before, you could not condition a Li-ion battery. It starts to degrade as soon as it leaves the factory NO MATTER WHAT YOU DO and basically dies within 3 years from the manufacturing date.

I guess that's what I meant. Thank you guys for the responses. I charged it fully, then ran it to shutdown, then charged fully again. So far, so good.

Source for GOOD batteries?

I'm getting pissed with all the POS oem batteries for the S3 these days. Is going to Samsung direct my only option to get a GENUINE one? I don't see where they sell them and I don't trust eBay based on experience.

I know you can get them at Office Depot. Or you could at least, several months ago.

Pick up some Anker 2200s on Amazon or similar store.
Who cares if battery is OEM? Just get one from a reputable company.

Great I'll look into it.

Are you certain your issues are the batteries and not your setup and use of your device?
There are lots of things that can lead to miserable battery life even on the most solid of batteries.

Sure. Brand new phone just purchased. Very few programs installed. Battery used was purchased off eBay. When indicator light showed fully charged I unplugged. Battery remaining went immediately from 100% to 88%. After 6 hours of light use, battery was already down to 40%. Within 20 minutes it fell off the cliff and phone turned off ... basically fully discharged.
Next, stock battery installed. 1 day 12 hours later battery still shows 55% remaining.

In that case I'd recommend Monster ZeroLemon 7000 MAh again.People here on XDA have really tried to suck every drop of juice out of it. It had stood all that abuse very well. Buy it from Amazon so you have solid Return Policy in case of trouble.

Thanks, I'll seriously consider it though the added thickness is a concern. If I could get 2 extra batteries close to the performance of the stock battery and at a combined price close to the ZeroLemon I would be satisfied.
How long does it typically take to charge one of those monsters?

I don't think their form factor would have issues with the SIII's casing.
I do believe they take roughly 4 hours or so with Samsung's original Charger. I don't have one myself so I have second hand information. It is true that if you have a Fast Charge Kernel, this is further reduced. I am guessing, if you charge off of a PC, of course it will practically take forever to finish :laugh:
My 1 year old stock battery goes me 3 days if on Standby all the time.It will last 1 & 1/2 to 2 days if I use conservatively.

Just fyi, fast charge kernels only make a difference when plugged into a PC and maybe a DC (car) outlet. And correct that the batteries should be the same size and ought to work fine. Only real thing to make note of is if you use any NFC features make sure the battery you get has this capability.

Bit OT here, but my regular Kernel KT747, now (in recent version) has special code for the 11th pin of the MHT port. So I am given to understand the Fast Charge thus implemented actually affects the way it charges off wall. I am testing since yesterday.

The theory behind fast charge kernels is that when you plug into a PC it detects the data connection and limits charging to 500ma or so. Fast charge kernels allow you to disable the data connection, thereby fooling it into thinking it's plugged into a normal charger and bypassing that limit.
The extra pins don't have anything to do with charging. Only 4 of them do. Before fast charge kernels were introduced people would sometimes short two of the wires in the connector (usually with solder) to accomplish the same thing.
As I understand it the 11 pins are just used with the MHL adapter for HD output. They don't have anything to do with charging. Otherwise a basic USB cable probably wouldn't even work.
I believe there are a few in depth write-ups about fast charge kernels here on xda if you want to search for more info on it.

[Q] Buy a new battery

Hi all!
I use the gadget about 2 years or more. My Battery is very bad... 1.5 hours of screen!
Can you tell me, where i can buy new REALY original battery for this phone. (in US).

I've seen good things about one on Amazon. Which ROM are you using? Also, which kernel?

My guess is a battery issue...not a bad battery tho.
Why not get gsam and post some screenshots after a good long drain?
Your setup, usage and apps have surely changed over time. Something is likely draining your battery.
Read the first 3 posts in the battery thread in my signature.... Its for the N5...but most info is universal.

Ok. I've seen some good things about Anker batteries (like this one:http://www.amazon.com/Replacement-T...H-I515/dp/B0078WL4YO/ref=cm_cr_pr_product_top)
With a new battery, do a full charge, full discharge (until phone dies and will not turn back on), and another full charge.

+1 for the anker 2200mah replacement. It's cheaper than the oem battery. It lacks nfc though. And as for the whole "battery memory" thing, don't worry about it. Just pop the new battery in and use it however. I just bought the anker to replace the original battery in my wife's s2, her battery life has doubled.

I just bought the Anker 2200 mAh battery and its great. My phone does last a little longer on standby, but my screen-on time hasn't increased by very much (I typically get about 3-4 hrs screen time).
I'm running CarbonROM + Wildkernel and other various tweaks for battery life. My phone spends most of its time in deep sleep.
When you open your battery stats, what things are taking the most out of your battery? I've found the app Wakelock Detector to help a lot in tracking down battery drains.
play.google.com/store/apps/details?id=com.uzumapps.wakelockdetector&hl=en

GSAM gives a much easier to understand picture of battery usage. If you're rooted, get Gsam root companion as well to see held awake stats. ?
