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.

do any of the new ROMs out give better battery life than stock?

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.

Extended Battery that is not bulkier? (can use original battery door)

hi does anyone know of an actual battery that has more capacity but does not require a bulkier battery door?
and most importantly, that it DOES give you more battery life?
because i once bought a 2000MaH battery for my HTC TP2 on ebay and that was the biggest scam i fell for, the stupid battery gave approximately the exact same battery life as the old battery... which was 1500MaH

Yeah the batteries that do not require a bigger back door are all going to perform the same oem or worse. So you can get a cheap charger and and extra oem battery and do that,or say **** it and get the big ass battery

ahhh the eternal quest for the holy grail of batteries. nope, it's not possible. not until battery technology improves. If it was possible to have a better performing battery that was the same size HTC would of put it in their to begin with. check out batteryboss.org for proof.

I did check it out! What's wrong with the 2150mAH TP2 battery as an option? I ordered one. Thanks for the link.

Here's one: Mugen Power Extended Battery 1800mAh for HTC Evo 4G
However, the reality is that Manufacturer claims a 20% improvement in battery life. Depending on your use that may or may not be significant enough. I'm just running stock battery w/ custom ROM (Damage Control) and some system tweaks which significantly improved battery life (errr, at least resulted in less battery drain

The 2150 OEM TP2 is the official HTC extended battery, its thicker and requires a extended battery door.

The "1800mAh" Mugen tested identical to the 1500mAh OEM battery.. save your money. http://batteryboss.org/results/NewMugen1800mAh_vs_NewOEM1500mAh.png
IMO the best option is to tweak your settings.. Im getting as much as 30 hours out of my OEM 1500 battery now. I also have 3 spare
batteries in case I ever need more juice. they are quite small and fit in a wallet fine. i've yet to actually need one. You could also try
this, which was told to me by an HTC Rep (and it for real almost tripled my battery life!)
"To also help with Battery Life you can do these steps exactly: 1) Turn your device ON and Charge the device for 8 hours or more 2) Unplug the device and Turn the phone OFF and charge for 1 hour 3) Unplug the device Turn ON wait 2 minutes and Turn OFF and charge for another hour Your battery life should almost double, we have tested this on our devices and other agents have seen a major difference as well."
you only need to do it once, and then again each time you flash a new ROM or do an OTA update.

did this method of turning the phone on and off and charging the battery for another hour improve battery life for anyone?

30 hours? you joking right?
If you getting that much why in the world would you have the need for an extra battery let alone three?
I call BS

That's hardly BS.
I easily get 30+ hours out of a single charge.
Right now im at 22 hours with ~45% battery life on stock 1500mAh.
It's a rip-off to get an extended battery because they don't perform as well..

I am waiting on a 1750mAh spare battery that fits with the standard back plate. If it works well, I will advise.

what is your up time though. i have an 3500mah extended battery and i don't get 30 hours still

I keep 4g on
I keep data always enabled too.
Do you?

I get over 9 Hours with BT, and data on all day. I have a task manager that shuts things down every 30 mins "IGNORE LIST messages, gv dialer, clock, task manager" Without it I was getting 4 hours. I make calls and surf the web and watch my porn clips during the day, so it does get used. I sent for the 1750 yesterday so I will update this after I get it that thing going. And the new batterys do have to be charged and discharge like 20 times before the hold a charge as well as they say it can.. Batterys on ebay=joke, buy the name brand ones. I used to make r/c battery packs and they have a peak run time in life, and its not the first time you charge them. It takes time..

I went to eBay and bought the "HTC EVO 4G BATTERY 1800+Dock USB CHGR SPRINT TOUCH PRO2" from vendor Chichitec. Vendor is located in California, so no sketchy chinese vendor, high ratings and fast delivery.
I haven't really timed how much more usage I'm getting with this new battery, but it does last longer, trust me.
The separate wall charger also seems to charge the OEM battery better than just by using the usb cable on the phone.
Not a bad deal for $19.98 at your door.

I get anywhere from 20-40 hours on a single charge(OEM battery) depending on my usage running Damage Control 3.2.3 with netarchy's 3.7.5 kernel, setCPU and Advanced Task Manager. I have setcpu keep the CPU @ 245mhz when the screen is off and 245mhz-1113mhz(on demand) when the screen is on.
I also use Advanced Task Manager($0.99) to kill out the programs I'm using with a widget/button. Whenever I'm done using the device I quickly hit the kill button(which doesn't kill the normal essentials) and shut the screen off which down-clocks the proc to 245mhz.
Today for instance:
-unplugged at 07:00
-GPS on, Wifi Off unless needed, 4G Off, Bluetooth On during travel
-beautiful widgets updating weather every hour via cell triangulation
-stock weather updating every hour
-used for slacker via the AUX jack for 45mins-1hr on the way to work
-1 bluetooth call in between listening to slacker on the car
-about 10-15 calls today while at work
-about 10 emails came in and I read them
-browsed web for prob 20mins during lunch on office wifi
-used for slacker via the AUX jack for 45mins-1hr on the way home
-rebooted device
-made 1 non-bluetooth call, sent a few text messages, and then posted this
I'm now at 61% battery remaining and probably won't charge this until lunch or on the way home from work tomorrow. I would give my up time vs awake time but I restarted the phone an hour ago so those figures aren't there anymore.
So, BS? I think not.

I have read what batteryboss has said but I can tell you I get 3-4 hours longer use from my 2000Mah battery. Now I am seeing a big drop off with Froyo but it is on all my batteries, even the OEM.

[Q]Legit 3500 mAh battery?

I want to extend my battery life. Wondering if anyone's tried anything but the stock 1850 mAh battery? If you have, please provide a place to purchase it. Thanks

JUST GOT ONE IN FROM CHINA...WILL REVIEW IN A COUPLE DAY...IT DOESNT SEEM TO READ THE TEMP RIGHT...trying to kill it now ( i know it doesnt matter but i like to see how quick i can kill it off)

Those batteries are a scam..why bother getting a bigger one anyway, not only do you lose Nfc, the stock battery already lasts a whole day easy

I don't get the problem with the battery, I can watch shows and movies all day at work and still come home with at the worst 40% battery life

its not 3500 mah but it is longer than stock

Innocell 3800mAh Super Extended Life Battery
I have used Seido Cells with G1's before and they were still running just like new after 18 months of heavy usage, twice the battery life over stock. The case looked better on the G1 as the back was flush. On one of the phones the case did crack and break after a 3 ft fall. It was a cheap and quick replacement from Amazon, under ten bucks if I remember right.
The one offered is a 3800mah at 69.99 and shipping now.

I really want a better battery too, I'm waiting for ANKER to make one for the t989. I have no idea how people manage to squeeze so many hours from there phones on this stock battery, but I usually go 5-7 hours before it dies. I'm not a heavy user but I do have my screen to 100% all the time. I don't mind carrying spare batteries.

If people are really concerned about hte battery life etc, just get one of those mobile chargers. They will charge everything from laptops to cell phones...they are called power packs.
first link on google...came up with this. http://www.amazon.com/Energizer-XP4000-Universal-Rechargeable-Power/dp/B0029U2WTG

There is a lot of fraud on these extended battery

Yeah i agree, there is a lot of fraud with the battery packs. Someone should regulate them and make sure that what they advertise is true.

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?
Thanks.

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.

Fry battery 4000mAh not worth it

[I posted this in the general G3 accessories section too, but in case you didn't see it]
This one:
http://pages.ebay.com/link/?nav=item.view&id=171470554241&alt=web
I get it, it was a long shot, but for ten dollars I figured I'd try. Like I'm sure everyone would assume, this battery does not last as long as stock. I know SOT varies by user, but with the stock LG battery, I consistently got 35 minutes SOT per 10% battery used. With the new battery, it was 26 minutes SOT per 10%battery used.
I followed the instructions of fully discharging until the phone shuts off and then charge to 100% 3 times and still no change.
It's not a bad backup, but it's also not performing like an extra 1000mAh should.

Crap I ordered a similar 3850mah that will probably be the same. Obviously LG thought hard enough about battery size prior to release. Perhaps it could've been 3500 and still stable though.

Someone on Google+ in the G3 community ordered a 3800mAh battery from Hong Kong and he reports he's getting 25% more battery life over stock. So you might be OK. I was going to order the one he did, but got power greedy and found this "4000mAh" one. Sad thing is, they were both about the same price, so there's no easy way to tell if it'll work better or not.

Get the right kernel and mods and your stock battery will last you all day.

I've tried. But without losing out on actual features like Google now always listening, location services and what not, it's not that easy. I didn't buy this phone to not use features, so I was just looking for a larger mAh solution so I don't have to turn off useful features for the sake of battery life.

I bought the TrendOn brand batteries. It was two 3000 mAh batteries and a charger. They perform as well or better than the OEM battery.
