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.

[Q] Mugen Battery strangeness...

This is my first post on here,but I've been lurking for ages I just bought a Mugen 3200mAh battery from MugenBattery.com.I already know about not having to condition it(lithium ion),so I ignored the instructions about cycling it and plugged it in and used it right away,and at first it seemed okay for around an hour(I didnt use it at all up to this point,just left it there until I needed it).When I went to unlock my Vibrant from suspend(pushing on the power button),the phone shut off and seemed like it was rebooting...but it just had the first screen you see(the one with Samsung and Vibrant on it) blinking on and off,even when I plugged in the charger in this state,all that popped up was a battery that also blinked on and off.The only way to get it going again was to pull and replace the battery,and it went back on again...then did this all over again when it went into suspend and I tried to unlock it.All the while,the battery stated it had around 75% power,so I have no idea what could have caused this.I put my cheep chinese 2700mAh battery back in and all was well again,so I know its the battery,not the phone.Anyone else have or seen this problem before?This is the most expensive battrery I have ever purchased for a phone at $88.00US....I hate to think that a cheep($20.00US) chinese battery has better quality control than it....

i think you need to charge it for 12 hours first.

Thanks,you were right! An overnight charge of around 12 hours did it.This is the first phone battery I had to do that with to get them to just work at all.Seems to work just fine now Again,thank you!

Let us know how long the battery is lasting once you get a few cycles please!

Yeah, you should run the battery dry, recharge, run dry, recharge and after a few cycles your life should improve.

Will do,just need a few days to do it,its lasting a looooong time!

NO, NO, NO. PLEASE stop spreading bad information. This will HARM the battery, and will have 0 benefit. The only "benefit" you can get from this is that the battery meter on the phone's firmware will be calibrated to show a more correct remaining %. You can achieve the same by charging the phone 100% (overnight) going to clockwork recovery and selecting 'wipe battery stats'. Calibrated or not, the battery will last the same, regardless of what % left its showing.
Again for posterity, REPEATED DISCHARGING OF LI-ION BELOW 20% IS BAD FOR THE BATTERY, IT'S PHYSICALLY IMPOSSIBLE FOR IT TO GET BETTER.

I am having a similar issue with a battery that I ordered off of ebay. It's 3500mah.
When I plug it in it will turn off and get stuck in a boot loop on the vibrant screen, but if it is off then it won't turn on at all when plugged in. It has been plugged in for 9 hours so far and it doesn't even show the charging animation or anything.
Normal? Or is the battery defective?
Thanks.

Ok. After charging it overnight and still nothing, I'm going to assume its broken. Thanks.

...and it does get a bit bulky,weight goes up to about double the amount,but it is so worth it,and then some!!I went from 6 hours on the stock battery to over 18 with the Mugen,and thats with heavy use(full brightness/live wallpaper,etc.).If you dont have access to a charger outside your home,this is a great buy,and you know the quality is there,unlike the uncertainty of the cheep chinese ones.Highly recommended!

The OS needs to learn your new battery. Just takes time and usage.

I am not so sure about your information. This is what DHGate, a wholesale Chinese online store wrote about the 3000mah battery for Galaxy S [not MUGGEN!]
How to use a new battery:
1. First when you received the battery,. you need to release the power in the battery, just put it into your phone without charging.
2. After the battery power is out, please charge it about 12 hours in first three times.
3. So the battery will be actived. So you can just charge it about 5-7 hours when use in the further.

No controversies at all. Your info from the link is outright wrong.
Mannymal is correct on this one.

I also have this battery. By the time I got it, Team Whiskeys roms had gotten good enough to where I didn't need an extended battery for day to day use (stock battery usually has 30-40% when i go to bed), but I do use it when I travel, so I don't have to worry about using it like crazy. The battery lasts a long time, probably like 2 or 3 days if I actually tried to drain it, at least. And it's definitely adds bulk, but it's reasonably well made and feels sturdy.
My only complaint is that I sometimes cover the speaker with my finger when I want to silence it real quick, and it doesn't work with this because the cover's so far from the speaker. But that's just my weird thing.
Also, yeah, don't kill your battery. No es bueno.

I use a seido innocell battery and it works great after a few over night charges. I get about 8 hours average of talk time. The battery is pretty small compared to the one accessory greeks sell. Even though the ah battery ia twenty five dollars, that is like the entry level name brand battery, it will lady you a while longer than the cheap ones on ebay, but I don't knower about the ones on ebay although I do know about the one ag sells skies down charging after about 45 percent charging. The seido is charging pretty fast for me and is half the price of a mugen, the next battery I'm going to buy will be the nugent, not because I need it, just
Cause I want to enjoy it.

Sieidio Battery 1750mAh Extended Battery Review

I purchased the Sieidio Battery 1750mAh on Amazon about a month ago. This battery is not worth the money at all. If you want an extra battery then I suggest buying an OEM battery.
I might be wrong but I think this battery actually goes down faster than the one that came with the phone. My biggest problem with this battery is that it does not fit properly in the phone. It can just be set down or place in my pocket and that is enough to make the phone.
DON'T wast you money on this battery

I don't even understand your review, but I guess I do understand you are being negative.
But this battery works way better than the stock battery that came with my EVO. It ****s on the stock battery. Diarrhea.
Maybe it's just because I bought it for $50 from Best Buy. What a bargain!

I got two 1800mAh batteries for about $30, and experienced the same thing. After awhile though, I realized that you have to do a few things to get better battery life.
1) Charge the battery to full while the phone is on.
2) Unplug and plug back in to verify that the phone is fully charged (green led)
3) Turn the phone off
4) Unplug, plug in, and wait for a green led
5) Repeat that 5-10 times
6) Then while still plugged in, reboot into Recovery and wipe the battery stats via the advanced menu.
7) Reboot, and use your phone as you normally would.
This may sound like alot, but it really only take about 5 mins. Even after wipe, it will still take about 5 full discharges to reap the better battery life. Hope this helps!

I think its just luck of the draw on aftermarket batteries (the cheap ones at least)
I have heard good and bad on ALL of them.
I got the Chichitec/htcexpress 1800 batteries with charger. Came in the other day and I couldn't be happier. 14 hours on initial charge, that's unheard of for me. On my stock battery I had to keep the phone plugged in most of the day at work just to still have juice by the time I got home. And supposedly these things start acting even better after a few charge cycles.
(Fits with stock battery door too)
But for every person that has a good experience with any of these companies, there's someone else with a horror story.

Could have told you that before you bought it, ratings by aftermarket reputable companies are close and never accurate...if they rate it at 1750, it's probably 1500-1650... The stock is 1500 so yes you wasted your money. Now on the other hand, the 3500 is the best investment anyone could ever make....

It's been proven long ago seidio over rates their batteries. The "1750" is actually just under 1500, so less capacity then the stock battery.
Sent from my PC36100 using XDA Premium App

just terribad in my opinion, gonna stick to my seidio 3500. rather have the size and life than a small size and a measly bump from the 1750mah battery

They rated it less than a 1500 stock battery.

Key with extended batteries is that you actually have to charge them longer than your phone indicates.
Example: I phone said it was fully charged at 3:26am in the morning. Yet it continue to charge until at least 6:45am before it was constant. Granted I am using an SBC kernel but even without, you need to let it charge the night. Don't let the green light fool you. It takes a few extra hours to charge even if the led light is green!
You should just about fully drain your battery and then let it charge overnight. If you aren't on an SBC kernel you may actually want to charge your phone while it's off so that the battery dictates the charge.
You should also wipe your battery stats once the phone is fully charged.
Try that and see if it works for you. I know that I was getting great battery life even on the stock battery. I play "Word With friends" (at least 15 matches running) a lot (at least 15 matches running concurrently) and this game actually drains battery. I still got through the day fine though I also carry a Touch Pro 2 and having the batteries that are the same size allows me to swap when needed.
I have the 2650mah one from sprint and my 3500mah seidio coming in the mail tomorrow. I'll probably write a review for it later. Note, On my 2650mah, it's already on its 12th hour and I was was playing WWF, surfing the web, made several calls and it's still at 77%. I will leave it off the charger tonight and see how it fairs tomorrow.
Good Luck!

I have tested these and if they do last longer then stock, it is only like maybe 20 mins. I have an external charger as well as running the SBC kernel to get a complete charge. I have the sprint 2600 battery as well and love it. Not many cases for it but I have modified a sedio rugged and ballistic to work with it. I let my wife use it for a few days in her evo and had to fight to get it back from her.

Sent from my Incredible 2 using xda app-developers app

I've read mixed reviews on these bargain batteries. We'll see I guess.
There were three 3500s left when I posted this thread.. now there's 2. Who else bought one?
I plan on running stress tests from full charge. (screen on 100%, gps on, wifi, data, fm radio, and google music streaming)

The best battery I used was 2 evo4g 1900 mah batteries for 7$ on eBay. The battery lasted 2 days with decent use but unfortunately I could not get it to charge with the phone on any rom... even though the polarities looked the same as our batteries.. if only..

Yea the $4 one came in yesterday and after 36 hours I can tell it's not as good as the original oem. It's not horrible and will serve as a decent backup.. but certainly not a DD battery.. no way.
I'm more curious to give the 3500 a spin. Hopefully that arrives today.

Can't wait to hear about the 3.5Ah!
I have a 2.2, I think. Probably could last me three days if I didn't surf and play so much.
Edit -
I should mention that I usually end the day with about 50% left.
Today I'm already at 14% at 6pm because I watched two hour-long videos and did all the other surfing stuff as well.
Curious what you use to test your batteries with.
I run Battery Monitor Widget Pro and always wipe stats for a new battery. Great app for tracking battery performance.

Sorry, I haven't been able to test much. The performance was so crappy the few times I did use it that it hasn't left my shelf ever since. I know I said I was going to do standardized tests but I've been super busy the past few weeks.
As for the anecdote- I charged the 3500 up to 100% and went out for a night on the city at about 2pm. It was dead by 11pm and I was pissed. However, I'm not willing to pass judgement on it yet because I was running PAC at the time which absolutely devoured whatever battery I used.
Now that I'm back on stable CM7 it's a bit different. I'll charge her up tonight and do some comparisons this weekend.

In my experience a battery needs to be exercised a few times before it "matures".

You're probably right. I'll have some more definitive results on Monday.

I bought a cheapo battery for my G1 from my favorite cheapo Chinese stuff website - dealextreme.com.
I think I got an extended battery for my OG Droid there as well, long time ago. They were ok.
I absolutely love big batteries. And paying as little as possible for them.
-MROM on DInc2

So I don't have any definitive results. Overall the 3500 does last longer but not by much. I ran it from 100 to 1 twice over the past week and made sure it received standard use and no charges. I have attached 2 screenshots of the drain plus one with the top culprits for drain. Like many 3rd party batteries it tends to take a nosedive once reaching ~18%. You have maybe 10 minutes left when it hits that mark.
My workplace has horrible signal so cell standby is probably much higher for me than it would be for most. For comparison, my OEM lasts about 14-18 hours without a charge.
Bottom line:
3500 mAh linked above- You can't go wrong for $9. It performs like a ~2500mAh. the case is good quality too.
1500mAh linked above - might come to the range with me next time for target practice. That thing is worthless and is maybe good for 4 hours of standard use. Streaming a 1 hour playlist from Google music used approximately 40% of the battery.

Good to hear.
It's sad that we can't trust the ratings on the batteries, but I am glad it worked as well as it did and that the cover was acceptable, too.
I've read a lot of battery reviews on Amazon and even then it's a tough decision to make. Like you said, for the $9 it's ok.
I'll never buy a $50 battery, but if I did I would certainly expect it to perform to the advertised spec. Sadly, the reviews on those batteries are as mixed as the reviews for the cheapies.

Some interesting information
Bought similar battery a few months ago. On standart battery I has only 10-15% left at evening (music, instant messaging and serfing drains battery wery well), with this enhanced battery my phone lasts 2-3 days. I attached the photo to compare it with default battery.
The main disadvantage of it, suddenly, was the incredibly low signal level (only 1 bar on WCDMA in wooden house, 2-3 bars on GSM), problem was in antenna that is located at the down of back cover. As you can see, two contacts was joined. Just split them, and signal should improve. It helped me, but not too noticeably. So, I have to put copper wire on the back cover and even to prolong it beyond. It looks very ugly, but now signal level is even better than on stock battery (always full signal level on the street even in 3G mode). Low signal level results in higher battery drain and heat.
I don't know why HTC decided to save money on antennas in our phone. Because stock battery cover GSM-antenna is worse than any Nokia (it's much smaller, but in antennas, size matter, a lot). Wi-Fi antenna is bad too.
Also, battery indicator in our phone is not works as it should, I think. 0% is actually not zero level. Real Lithium-Ion battery zero level is 3.2-3.3V (sometimes even smaller, but it's not recommended to to discharge it beyond this level, it may damage battery), but HTC controller tells 0% at 3.5-3.6V and Android forcibly powers off the phone. When I used De-Sensed V firmware, where Android power off function on zero battery level not worked (may be, it was disabled in services.jar, there is the way to do this thing), I could run up to one hour in ICQ on 0% and even some hours in idle mode, before the battery controller blocked battery discharge to protect it (voltage was around 3.2V). It's disappointing that I can't make an urgently call while I actually have the power level enough to do this.

Thank you! Very nice to read your solution for the antenna!

When I used De-Sensed V firmware, where Android power off function on zero battery level not worked (may be, it was disabled in services.jar, there is the way to do this thing), I could run up to one hour in ICQ on 0% and even some hours in idle mode, before the battery controller blocked battery discharge to protect it (voltage was around 3.2V). It's disappointing that I can't make an urgently call while I actually have the power level enough to do this.

AckerMAN_ can you give more details about your antenna fix?
I see in the photo that the cover has two plastic fingers that are painted with copper colored paint.
My cover has metal fingers attached to it for the connection. They are like springs.
Can you attach a photo of your antenna wire, please?
This phone is famous for poor signal and many others would be interested in a way to improve reception.
-MROM on DInc2

There is a photo of back cover with attached wire. Also, I attached the screenshot of current reception level. I hope it will be useful.
Also, I'm thing about patching services.jar, I'll try it when have enough time.

[Q] Does this mean my S3 needs a new battery?

Ever since last week, my battery has been misrepresenting the % of battery. For example, last week, I had fully charged my phone in the morning and it said 100%. Right after I pulled out the charger, it said it was at 60% battery. When I used my phone, it dropped 1-2% every minute. I thought it was an app or something that was doing this, so I installed Battery Doctor. It didn't really make a difference.
I'm posting this, because right now it's worse than ever. It said that I had 100% battery and then right after I pulled out the charger, it said it was at 56% battery. After I closed the screen, it said 100% battery again. Then it started to drop %'s every few seconds.
Some information that might be handy:
- I've had the S3 for 1 1/2 years now
- Was rooted, after update, root was removed and I haven't bothered
-Attached to the pictures are two pictures of my battery today. I haven't done anything but screenshot twice.
Also if it is a battery problem, what type of battery should I get? I'm thinking of buying an Anker 4400 mAh Extended battery (http://www.amazon.ca/Extended-GT-I9300-T-Mobile-Cellular-EB-L1G6LLU/dp/B009GVG8FA).

Chances are that your battery is dying. I don't really know which one is best to get as replacement though.
You should also take a look at what is using your battery, there might be more than a dying battery (app, system). Can also get OS Monitor to see if something is over-using your ram/cpu.
N.B.: Extended battery makes your back cover much larger, you'll also need a different case (if you're using one).

Nothing's using up my battery because I checked through a multitude of apps and the processes running were all the same as before my battery was really dying. I do have a case so I guess I'll just try to find a smaller battery. Thanks for confirming my suspicion about my battery!

I have the ZeroLemon battery. 2300 ma. Same size as stock battery. It was a good deal. They give you 2 batteries and wall charger. Only downside is it does not have NFC. I don't use it so didn't bother me.

I got the zero lemon 2300 and I went from 1.5 hrs of screen on time to a little over 4 hrs of screen on time. Once while doing nothing but watching videos I got 5.5 hrs. My phone is the same age as yours. Seems that is about the lifespan of smart phone batteries.
edited to add that my phone would lose 2.5 % an hr while idle, but now it's only 0.4%.
