3500mAh Extended Battery From Amazon Question

I just recently bought a 3500mAh extended battery from amazon. (http://www.amazon.com/gp/product/B0042TY68C/ref=ox_sc_act_title_1?ie=UTF8&m=A1N1UQZS4G6GV9). I just got done fully charging it, i let it charge fully over night, just unplugged it and boom 10 minutes unplugged with me not even touching it just letting it sit on my desk we are down to 95%. I know you are suppost to cycle these batteries and stuff before u can actually see the fully life of it and i plan to do that. My question is i downloaded battery monitor widget and on the main screen its calling the battery a techno-Li-ion 1425/1500mAh battery. I know this isnt right ive cleared battery stats probably 10 times total now, through recovery and through the battery monitor widget app. Im hopping i didnt get ripped off and it just takes a few discharges for the phone to recognize the new battery? Any help would be appreciated.
I plan on letting the battery get to 15-20% and then charge it all the way up again and do these a few times, as well as clear the battery stats. This is what i read to do with new batteries? Please correct me if im wrong..

When using an extended battery you are not going to get a full charge unless you condition it or you could use a SBC kernel.

how much will u get out of it then without the sbc?

I bought this exact same battery. I used it at the time on my Evo unrooted. The first one that came to me (2 weeks late) wouldn't even power up. The second one they sent me I ran for about 3 weeks and put the stock battery back in. I was about to get 9 to 12 hours on my stock battery and with this extended I was getting the same. 2 weeks into using it the battery life got crappier everyday. To me it wasn't worth the added bulk for the same or less life. Since then I now run CM7 on the Tiamat sbc kernel with my stock battery that is almost a year old and get close to 18-20 hours out of an almost year old stock battery.

I use the SBC kernel, battery monitor widget, and the 3500mah battery. The thing lasts for days. Literally. When the green light comes on at "100%", that means NOTHING.
I ran it stone cold dead yesterday on purpose. Plugged it in at 10:00pm using my 800mah AC charger.
10:00pm: Plugged in, begins charging at ~700mah (max for my charger)
12:45am: Phone indicates 100% @ 4018mV but keeps charging at 700mah
2:00am: Charge rate ramping down @ 4197Mv
2:45am: Charge rate 100mah
3:00am: Charge rate 50mah
4:00am: Charge rate 15mah
4:30am: Charge rate 10mah which it remains at when fully charged (4198mV)
Stone cold dead to green light was only about 3 hours. BUT, stone cold dead to actually fully charged was really double that.
Obviously if the battery isn't dea, it will take conciderably less time. If you charge it with a PC, limiting the total current to 500mah, it will take conciderably longer.

So battery monitor widget calling it a 1500mAh battery doesn't mean anything? Right?

Ahh... yes. I know now which one

I have the exact same battery and I'm wondering is the percent shown total BS? Mine is showing 87% with 4000mV left after charging overnight with an SBC kernal.

Yea I'm at 8hr40min as of right now @ 17% battery. I've had my display backlight turned down and have been at work the whole day doin nothing with my phone but light texting and posting in this thread. With my stock battery I get around 12 hours before the phone almost dies with regular/mild use.I'm starting to think this battery was a rip off.. hopefully once I charge it back up it will last longer but idk... If anyone has any tips or tricks to make this battery last longer please help me out.

The newest version allows you to override that. Previously, the phone was telling it the capacity was 1500mah because that what the normal battery is supposed to be. The new version let me change it to 3500. So the % estimation should be accurate now. It is claiming I have 70% remaining or 2450mah. And 70% of 3500 is 2450. Now, where it came up with 2450, I have no idea.

The first time after ur charged the battery when u got it did u let it completely die or plug it in when it hit 10% or so?

My first full charge on the same battery I got the exact same behavior. I was on the Stock Kernal that came with CM7.
Second charge, after changing to the Tiamat SBC, my battery is screaming... 6+ hours of heavy usage (video, web, lots and lots of text and 30mins of calling) and I am still over 50%. By now, I would have had to charge the regular battery...
Very pleased with this thing...

well im about ready to unplug mine for the day and see how it goes, i fully charged it with the phone off with a wall charger. And have been cycling it witht he phone off by unplugging it when the light turns green, waiting for the light to turn off, then plugging it back in until the light turns from orange to green again. Ive been doing this for the last hour or so because somone in another thread about this battery said it help him out alot, i did unplug it when i first woke up and it dropped from 100 to 92 within 3 minutes so thats when i tried this cycling, i did unplug it in the middle after doing a dozen or more of these cycles and it staid at 100 for quiet a while then dropped to 99 after about 5-6 minutes of being unplugged and me browsing the web and market this being a huge improvement so id have to say the cycling of the battery does help idk how or why but whatever im not complaining ill post back later tonight once i see how the battery acts.

So far I've had terrible luck with this battery can't get more time than stock. Charging it with an SBC kernal and it doesn't help, was avoiding spending 60 bucks on a battery but I think Ive no other choice.

im at 2 hours with it right now, down to 70% i used it pretty heavily about 30min ago to reflash cm7, savagedzen sbc kernal, download all my apps, setup launcher pro plus, and re confiugre everything. It dropped rather quickly from 100 to where its at now so i guess we will see, BMW is estimating 10hr40min remaining battery life right now which would put it at about where my stock battery would die at around 12-13 hours, so we will see :-\
*edit*
BMW now saying 12hr10min at 70% battery? weirddd...
*edit*
BMW now saying 16hr23min at 65% battery, ive been using it moderately, used 4G for a second and WiFi for a few minutes as well...

Here's why the drop...the Evo along with other phones use bump charging to charge the battery meaning when the light is green you have anywhere between
90 and 100 percent at 89 percent down to zero you should not see such a dramatic drop...its a Evo thing the large drop

How do you override that value? I looked all through the widget settings and I'm not seeing it.

go into bmw, go to settings, monitoring preferences, second from the bottom battery capacity, just change that value from 1500 to 3500, took me a while to find it as well.

Bought extended battery today how to set up phone?

I was wondering how i would set up my phone. Reset batt stats, longer charge times or something on how to get the best out of the extended 3500 battery. Also any hints or advice?

i have the same one and i just cleared the stats after charging the battery till full.

Sorry bad post delete please. This message just this one lol.

How do I know its full. ? Just over charge it with it on or off?. That's what u wanted to know. And does the percentage become accurate after doing this?. As I understand right now it should only register at 1500 right until the batvstats are chnage and then registers as 3500. And should display % based on that

i let mine charge until the green light was on, then unplugged and waited for the light to go out and re plugged did that a couple times until light is orange and charged till it was green again. havent had any problems.(knock on wood)

Do you know how long it took for that process? im getting it green now and will do the rest tonight with it being off. I am hoping that it registers the full battery capacity.

I've had very good luck with a $7 Chinese 3500mah from Amazon. I reset my stats through my battery widget but not until weeks after I had the battery. I don't think I was rooted when I first bought it.
The first day I got it I installed it and it showed 66%. I ran it down to 0% which took a pretty long time. Supposedly that's important, several cycles of complete discharge.
I have this docking station that is absolutely worthless as a docking station, but pretty awesome as an external battery charger. I use that to charge it, and sometimes charge it while its in the phone with the stock wall charger. The phone recognizes the %'s pretty close. At first it would drop to 80ish% pretty fast and then be really long between 50-80. Now it seems pretty steady all the way through.

Hmm I never thought to run down a Li-Ion battery due to it not actually having a memory.. Well i got it fully charged and I will see how long it takes to run down.
So I am waiting on how things will go for it lol. Thanks for the help guys. If anyone else has anything else feel free to chip in.

Get the battery monitor widget int he market, go into the settings and make sure you set it for the maH that your battery is, and then try the guide in my signature.

I have had my extended battery for some time now. I don't have BMW and have no history out my battery on my phone. All I did was put the extended battery in, played with the phone like crazy, killed the battery all the way, kept the phone off and charged it until 1 hour after the LED turned green. No issues.

I'm in the middle of a record setting run right now. This is very unusual. Usually I get 16-24 hours. My battery and EVO seem to have a mind of their own. But when it works it works good. I still struggle with intermittent 'android system' battery problems.

Bad battery, wake issue or usb port/cable?

So after some time I've been battling with my battery life through the day. Few months back it was great, Id easily get a day no problem! Then I found I had a wakelock issue and had that fixed.
I now suddenly have almost multiple things going on at once but first a small back story.
Went to bed one night and had it plugged into the wall. Went to bed at 60% and woke up and my phone was down to 6%. I thought, well the usb port is bad or the cable. Took it into the sprint store, they of course say "it looks like its charging just fine, the light is coming on" (the light was on during the night too).
They checked the battery and they said it was bad. Im wanting to take it to another store and have them check, because either: they didnt want to replace me with a new phone or replace the usb port if thats bad.
1) Bad battery- in a matter of 30minutes (during my lunch break at work) my battery dropped from 63% to 14%- only used 3g for facebook and sent 2 text messages. And my phone is undervolted and underclocked
2) Possible bad usb port- I plug my phone in all day at work, and 90% of the time the screen is off. The % of the battery doesnt increase, but maybe decreases slightly (I have data and everything turned off while at work because I get no data signal).
3) wakelock- so suddenly I'm getting a huge percentage of system usage of 54% in my battery stats. A few months back it was maybe 1%? I flashed the .img that sets the wimax, PRI, NV, etc to what fixed the issue back then. Im just confused how this has come back now when I havent even updated anything related only my rom (MIUI 1.8.26).
So I've ordered 2 2000mah batteries off ebay- I wasnt going to pay $40 from a battery story across from the sprint store (as they didnt have any stock, only extended batteries).
If anyone has had a similar experience, or would know what is the culprit would love to get feedback. Hopefully I can get this fixed soon. Maybe just a trial and error.

Something really strange just happened. I checked my phone just now and the battery is at 98% and just maybe 30minutes earlier it shut off because of low battery
What I explained before about using my phone on my lunch break was only 2 hours ago and showed 16%.
I always wipe my battery states when I update my ROM or install a new kernal.

Don't wipe battery stats if you don't have a full battery, it'll keep your battery from charging fully.
It may be the battery, but since you're getting new batteries you'll know then. If you didn't get an external charger, I'd suggest doing so. That way you can guarantee that your extended batteries get a full charge, and you can switch out a dead battery with a fully charged one if you keep having problems. The usb port on the Evo is crappy anyway, but if the light comes on and stays on & you can transfer data through the usb port then I doubt that's the problem.
It could be hardware failure, but wait until you get a new battery and have properly calibrated to come to that conclusion.
In the meantime download Battery Monitor Widget, that should show you your true battery capacity even if the system will not. You don't have to use the widget, you can just open the app. Once you see that your battery is fully charged, calibrate your battery properly. Wipe battery stats at 100%, let it drain until it shuts off, charge to 100% without breaks, and you should be good to go.
Good luck!

Thanks for that!
I just bought a battery from BB to hold me over (50$ for a 1750mah battery?! )
when it charges to 100%, should I go into recovery, or use battery calibrator (app)?
Ill install that battery monitor too

BMW has the feature to wipe stats. I also recomend to look at the reports and judge when the battery is full by looking at mV. 4200mV is full charge. Then wipe stats FIRST, then unplug and run down completely, then recharge fully with out unplugging.

Ya just noticed BMW had that feature. Forgot I had a menu button. LOL!
This battery I got at BB is a "1750mah".
You know what I realized what might be the issue? Back a few weeks ago, I bought an extended battery to use to take videos at a concert. At that point I wiped the battery stats at 100% of the 2500mah or so battery..

Nexus Overheating, Battery Draining

Hey guys, hopefully someone can help.
I have a Nexus with severe charging, overheating and battery drain issues. It's on stock jellybean, factory reset, no extra apps installed, and the battery will discharge in about 1 hour by just sitting idle. It takes maybe 2 days to actually charge to 80%. I'm about to replace the charging port to see if that will help.
However, it's also getting extremely hot. Not just mildly warm. And this is when it's just sitting there idle. Not only that, it's staying hot when the phone is off and not even charging. The only time it stops is when the battery fully discharges in about 2 hours... while the phone is still off.
Anyone experience this?
I have a grey market Galaxy Nexus which means I can't send it in for US repairs.

sounds like its time to replace the battery. is the battery leaking, discolored, warped, or "pregnant"?

Yes, I'm also saying it's the time for a battery replacement. They are fairly cheap, so you can fix it without spending too much money.

Nope, battery looks brand new, but I'll definitely order a new battery. Hopefully the ones on eBay are really OEM.

My battery gets to 122f while charging and wifi tether. I try to keep it near a fan and it helps some. But I don't have any battery drain issues. You probably just need a new battery.

New charging port, new battery and phone still charges extremely slow and drains real fast. About 20% in 40 minutes. Takes around 30 minutes to charge 2%.
Then when I take the battery out and put it back in, the phone thinks the battery is empty (I took it out with 30% charge left). Not sure what to do at this point since the only thing left to do is replace the mainboard which will probably cost more than it's worth.
Anyone have any other ideas?

Some screen shots
Sent from my Galaxy Nexus using xda app-developers app

After threatening to throw this phone in the ocean, it started working normally.
Trying to figure out what was wrong with it, opened it up again, put back in the old charging port (which had a higher revision number than the one I bought).
I waited 1.5 days for the phone to charge to 96%. Drained it to about 20% in less than 2hrs. Stuck it into the charger again but the battery was still draining. All the way down to 7% where it seemingly stayed stuck for a day. Then I guess it shut itself off.
Went to check on the phone randomly and saw on the power-off screen the battery had charged to 100% which never has happened and especially not in less than a day.
Turned it back on, started using it and battery drains sort of normally now. Overheating has also disappeared completely and now it also charges normally.
So in summary, I have no idea if this problem is going to resurface and I really didn't do anything to fix it. Though I would really like to know what happened to have it malfunction like this for almost a month.

Horrible Battery! I just dont understand!

The first month this phone was great on battery... Its horrible now 3 months later! I shut off all the samsung stuff that suck up the battery. I have the screen power down to the lowest setting. Sometimes when i charge the phone is says its fully charged and when i unplug it its about 98%. Does this once and awhile. I've been playing a games for about 1.5 hours. The batter is about 40%. Is this normal?

10 minutes later i just checked the phone and now its down to 30%... wtf is going on with this battery?

1.) You should get Better Battery Stats from the Play Store so you can see what could be causing this battery drain.
2.) When you unplug your device and it shows 98% it's a good thing. It means that your fuel gauge is working correctly. We have a safety feature that helps the battery to never get over charged. It helps the battery last a lot longer. The way these batteries work is if it's constantly overcharged over an certain amount of time it would deplete the battery life.

you have something in the background going on. could be a rouge app. check Better Battery Stats.

A coworker of mine has a Galaxy III on ATT same as I do. She complained about her battery to me. We both opened our Elvision Battery Widget and saw that screen times and time on battery were within 30 minutes of each other (1hr 50m mine vs 2hr 15m hers). She had 73% and I had 95%; her widget said 38XXmv, mine said 4100 (I have more stuff on than her). I had her restart her phone just for the hell of it, then I flipped through her settings and TURNED OFF battery saver. The problem went away. I've never used the battery saver and my battery stays golden all day. That said there's no telling if the restart did more for the phone than turning off the battery saver. I told her to turn on battery saver for 2 hours this weekend and see what it does. Will keep everyone posted.

Are you on stock?
Stock ICS on my S3

I'm rooted on stock ICS...

Google Now is a huge battery drain from my experience.

I'm rooted stock. No battery issues in fact gs3 has some of the best battery life I've seen second only to my hoxl.
Download autostart fromvthe market.
Find out what's running at os startup.
Disable. Things like googleplay, Googlemaps etc. Don't need to start up.
In fact the only thing required is integral Os components. At start up, I have alimost everything Google disabled.
None of your maps need time start when boot. None of them. Keep in mind I'm talkin aps like ....anything AT&T... w/e you dl'd from market.
Also go through and disable bloatware.
This will help. check your battery. It should be flat or slightly concaved. If it's bulging even slightly get a new one.
Report back and let us know.
