Cheap eBay extended battery question..

So I just got this battery hm around Wednesday or Thursday, and I have let it die down to around 10% or less and recharged it overnight several times and I still only see a slight difference in battery life. I am (I would say) a moderate user and I know some people say they get around 2 days on heavy use so I wonder what I'm doing wrong..? I ran the SU command to delete the battery.bin file to wipe the stats while it was fully charged, then let it run the whole day again only getting around 12 hrs (probably would have been shorter, but I have juicedefender running, and I was at work for 5 1/2 hrs of those 12) and then I stuck it on the charger at about 7:45 and then around 12 it was fully charged and I of course turned it off, then back on and it said it was around 80% so I let it charged to full, reset it again then when I turned it back on it said it was full. I took it off the charger and within minutes it dropped 1% every minute or 2 and now around 15 minutes later it's at 86% and I'm not even doing anything, just sitting here with the screen on and Skype is running. I've only drained it/fully charged it a few times maybe 3 or 4 should I just keep doing that or did I just get a crappy battery? It's better life than the stock, so I can't help but think that it's not crappy just not fully calibrated or "worn in" yet. Any help would be greatly appreciated!

I too have a cheapo extended battery from eBay, for the first week I hated it, but finally I actually just let the thing completely die to wear the phone shut down and wouldn't turn back on, then I recharged the battery completely in a standalone charger(also ebay), then put it back in the phone and used normally, charging and discharging and now I can't even dream of going back to the OEM battery, my battery life has much more than doubled. I use my phone like most here with CM7 up to date on nightlys and I'm happy as can be. I also like the ext back on the cheapos much better than the seidio flavor.

So you use the wall charger from eBay to charge it? I don't want to take my battery out to charge it though every night, let alone turn it off because I use it as an alarm clock :X. I've read a whole bunch of different ways of how to charge it in your phone and most people even one of the legitimate companies (Seido) who sells it, says that if you let it go an hr or 2 after the light turns green its good to go, but I don't believe it charges after the light turns green hence why the charging icon on the battery goes away. people may "think" it does but I honestly don't think it does and if anybody can prove otherwise I might have to buy the external charger :/

Yes get an external charger, Preferably 2 batteries and 1 external charger.

I just ordered a wall charger for like $15 I hope this works. I'll just charge my extended battery at night and use my other battery when the extended is charging

I used the external charger just once to "calibrate" the battery it seemed? Since then I've not taken the battery from the phone and just charged it with the phone charger(plugging it in) and I have noticed a huge change in run time.

How do you charge it though now that its calibrated? Do you just leave it on the charger for a few hrs after it hits green or do you have to turn the phone off and back on then stick it on the charger

Well my cheap battery has not blown up with sbc kernels

Yeah, its been about a week and my battery still can't even hold a charge, even if it isn't fully charging. It dies quicker than my stock battery. I told the guy I bought it from, and he said he'd send me a new one so I'm back to the stock battery for now until I get this one next week :/

Hey guys, i know it's a tiny bit off topic, but what about a battery pack??

i have two of those things and they work perfectly. plus, i don't have to kill the phone, open her up and swap batteries. additionally, it'll charge two devices at a time. bonus!

Hmm see that's what I'm trying to get rid of lol having to plug it in all the time. Plus I actually like the bigger back, I personally don't like the thin size of the evo I feel like I could drop it at any time.

How are you guys getting so many hours? I only get like 8 Hours on my heavy use and i bought a 3500mah extended battery wtf? I'm also using the net Netarchy sbc 3.2 more havs and mym rom with setcpu running profiles. What am I doing wrong? I even have juice defender running aswell.

I had my 3500 extended battery and at first it wasnt too good. But after switching to an external charger for all charges and completely letting the battery die out im getting a whole days worth of heavy use with no worries.
No rooting or any battery controls.

What's up with these batteries?

Hey guys, long time lurker, first time posting. Ive had my Vibrant since mid-October 2010 and recently started having poor battery life (i have been using Nero v4 since late Dec. With no probs until recently.
I bought 2 aftermarket batteries from the same seller on eBay. They arrived new, once inserted in my phone and a stock vibrant on 2.1, they worked fine but as soon as you plugged the phones into the charger the phone just keeps rebooting. The phone becomes stuck on the "vibrant" screen until you turn it off.
My friend recently sold his Captivate and gave me his spare OEM battery and it works fine. I'm guessing these aftermarket batteries are junk, but i'm just wondering what the problem is with them?
The seller never responded to the dispute, so I got my money back and two crap batteries LOL.

the batteries you got most likely have to be charged with an external charger

I was thinking the same thing! The battery worked fine in the phone, just not while plugged into the wall charger.

I've gotten a battery from eBay and its just fine. Only thing is that even though its "extended", it still sorta drains quick.

Did you drain it to 10% when you first got it, not plugging it into the charger?
I did that, and I've been streaming pandora on 3G (my data is gone lol) for about and hour and a half, and the stock battery would have gone from 100% to 85%, but this extended battery (2800mAh, but it says 3500mAh on the battery) has gone from 100% to 94%.
It depends really, drain it all the way, then re-charge it (wipe battery stats too, but I didn't and it runs great), and you should get improved battery life.

I've been told the opposite, not to drain it all the way but when you first get a extended battery let the phone charge 3-4 hours after your phone reads 100%. It worked for my 2800 mAH battery.

I did it the way I said, and my battery lasts 2 days easily on normal usage, like texting, and other things (not including data, that kills the battery, no matter HOW big it is).
I guess you can do it both ways, and they both work.

I bought me a 3500mAh Battery from ebay and it works beautiful for me. I drain the battery till its completely dead then recharge it 2 hours after it hits 100% and it lasts me 2 days with normal use. Its an awsome battery

Do you have a 3500mah battery? What is the best way you have found to charge it?

I bought a 3500mah extended battery about a week ago. When I got it, I turned off the evo, inserted the extended battery, and charged the device while powered off for approximately 8 hours. I did this for the first few days. Each subsequent charge, I plug the phone in, power it on, and leave it plugged in for approximately 8-9 hours with the Savaged Zen 2.2.1 SBC CFS kernel.
During this period, I was able to get about 12-14 hours of battery under heavy, almost constant usage. With light usage (texts/twitter/trillian) I was able to pull about 40 hours.
In the last few days however, my battery life has halved. It is still better than the stock battery, but not by much. I am able to pull in around 6 hours of heavy/constant usage before the battery dies. Has anyone experienced this? I've looked at all the tips and tricks and don't see anything that specifically addresses how to charge the bigger battery. I was under the impression that 8 hours with an SBC kernel would fill the battery completely.
Should I be charging the battery with the phone off?
PS: I have tried wiping the battery stats and that has not seemed to help.

I personally use http://electronics.pickegg.com/Elec...-for-T7373-Touch-Pro2-6341706512982200005.JPG
It's SOOO MUCH BETTER on the battery! Plus there's never a chance you'll pull it off the charger before it is finished. Just swap between your normal battery and the 3500 back and fourth for the best results. But everyone knows that our phones won't charge the batteries correctly.
A simple search for t7373 battery charger will take you to places to buy this at. DO NOT OVERPAY FOR IT! I got mine in a 20 buck package. got 2 batteries, this thing, 2 screen covers, case, and so on. 3 clear cases. lol bunch of stuff. on ebay.

try reconditioning the battery, charge until full(green light) the unplug and after light goes out plug it in again, repete until you get the orange charging light then let it charge fully(green charged lite). see if that helps

but all that's doing is overcharging it. The average person doesn't have that much time to waste. lol plus the only way it works is if you do it on a daily basis. However, the funny thing is HTC/Sprint actually posted that as an official fix. HAHAHA! It's really just a trick to get the not so smart people to do it and shut up. lol! It's not conditioning it. wait until battery is almost empty then swap battery and let it charge outside of phone. then put back in. ;-)
edit. just remembered. wasn't people having issues fully charging these 3500s? I'm almost sure they were. yeah. the only way to charge them fully is actually outside the unit! I COMPLETELY forgot about that! Did HTC ever fix that issue? I could be wrong. so need an expert in here to give a second opinion. thanks lol

so you think its better to carry and swap out batteries and reboot everytime plus buy an extra charger. no thanks, i'll do the not for smart people every once in awhile.
edit: dont know havent heard about any issues not fully charging 3500, or if it is better to use stand alone battery charger

charge it however you like.. I see no difference in results no matter how you do it.. the results in life completely depends on use and how much stuff you have on.. Getting in the habit of turning data off and sync, bluetooth, gps etc is the best way to extend battery life. Charging it full is full.. It doesn't make any sense whatsoever to "recondition" it.. when you fill something up.. how does it get "more full" than full.. logic tells you it's complete bs.. unless you want to believe it then I'm not here to convince you of what is and isn't.. Use the system settings toggles to turn your stuff off.. data and sync are the biggest killers.. You'll still get calls and messages.. just turn it on when you actually want to use your browser.. sittin in your pocket is just wasting precious battery..

Thanks for the input. I'm going to hold off on buying a charger and attempt to charge it as suggested in a couple of these posts. If that doesn't work, I'll invest in the external charger and report back.

GreenTea, any updates on this? I just bought the 3500 and an external charger (why not for $5 a piece). I'm wondering if there's any issues charging inside the phone and whether or not I need to wipe batt stats.

I know this is an old issue, but maybe I can add some input:
I have a Seidio 3500mAh battery I use for my Evo 4G (used it in the my HTC Hero first, then in my Evo 4G). I can get roughly four to five days with little use out of the battery (I'm using CM7.1 right now)...until I turn on 4G.
Once I turn on 4G, I may get eight to ten hours out of it with light use.
What you may want to do is keep the 4G radio off until you need it...this hopefully will improve battery performance.

You need to download BATTERY MONITOR WIDGET. Put the widget on your home screen. Monitor voltage while charging. Full is 4200mV. Anything less is not full. Recently, i can not get it past 4180mV. Sometimes, I charge overnight with phone off, then plug into my car charger going to work with phone on to try and top it off.
Calibration nor conditioning will fix the issue. It is the kernels and they just are not right yet for gingerbread.

With moderate to heavy use I'll be able to pull in 12-15 hours on a full charge with my 3500 mah non-seido battery. Light usage will net me about 40-48 hours. SBC seems to give a couple more hours if the phone is plugged in and turned on during charging. I live in an area without 4G, so I cannot respond to 4G battery use. I've heard it is a battery killer though.

Ebay extended battery charging question

Just this past week I got two of these extended batteries off of Ebay. Although I'm still calibrating the one seen on the charger. I really haven't found anything concrete on how long a battery like this is suppose to charge for? I've read things such as charge it in the phone (which the phone will charge it as if it's the stock battery) use the charger that came with it (charger in the photo continually thinks that the battery is at full charge, when it was in the phone until it died.) To battery calibration apps which I'm reading don't do anything, to bloatware. So if anyone can help me out, it would be great. And sorry if I made any mistakes in this, sending this from my phone is kinda hard for me.

I have the same extended battery and I can say that I have no idea. I'm using custom roms, and a charge lasts anywhere from a day to 3. I would say charge it in the phone til full, then drain it by using it, and do that a couple of times, it gets better as time goes on.

I have the same battery and when I use the phone to charge it it takes 6 - 7 hours and it lasts pretty good but since I've installed the shot of awesomeness by team inferno the original battery is good enough for my day... My max was 1d 14 hrs 10m 20s with 2% left... Big thanks to team inferno!!!

[Q] Extreme battery drain even with new battery and new charger on 4.4.4?

Basically as title reads. I've been having extreme battery drain. I thought it might have been my battery that was shot, so I bought a new one, as well as a charger. I even had a massive battery (don't know the mAh off the top of my head, and it isn't with me- but it was so large that it came with its own new backing) that also seemed to drain quickly. It seems the original battery would last 2-3 hours with barely any usage (a text or two; checking the time) and with regular usage (googling, reddit, texts) would be an hour. The large battery lasted 3-4 with barely any usage and 1-3 with usage. WiFi is off as well as GPS.. Only apps (besides what regularly runs) running are Handcent, Chrome, clock. That's all.
It also seems to discharge when charging and using my phone at the same time, so I have to leave it alone completely while it charges... And it charges really, really slowly. The large battery took 12 hours to fully charge last time I charged it. (I got a new one yesterday, seems my battery is still dying extremely quickly).
Here is what I am running on my phone.
Here is the new battery I ordered for it that I'm currently using.
I also use this to try to extend my battery life to a normal amount.
I am also waiting for this to come in the mail to help juice up my battery life to get through a day at work.
I bought a charger by RocketFish a while back at Best Buy which is what I used for a while before going to default S3 charger (brand new, I was originally using my S2 charger). Nothing seems to be helping.
So all in all, is my phone shot? Is there anything I can do to fix it? I'm not sure I want to go out and buy an S5 (especially with Samsung being so closed about bootloaders now). What can I do?
I'm using CM11 on 4.4.4

Well some people have complaints about Cyan's battery life so have you tried taking back to stock?
