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.

So it's already been established that after the EVO charges fully to 100% it then stops receiving a charge and runs off the battery before charge cycling again. All the while displaying 100%.
Has any effort been put into changing the way this operates? Seems like it'd be nice to leave the phone on a charger and when you take it off, it would actually be at 100% and not at some arbitrary percentage between 90% and 100%.
It's better for the battery life.It's really good option if you ask me.

You mean make it so that the battery's status bar shows a realistic value once it stops taking a charge, even though it's still plugged in, right? Not actually changing the way it takes a charge. I'd be interested in seeing that happen.
Is that why when you unplug it, the first 5% or so disappear within minutes?

Yup. This is why when you charge overnight the battery plummets right after.

Don't leave it plugged it after it reaches 100%. Problem solved.

Valid point. Lol
There are some people who don't want to wake up in the middle of the night to unplug their phone. Like me.
annoying, but just unplug your phone when you do wake and plug it back in after about 10 seconds. let it finish fully charging while you get ready.
it's better for the battery though, case closed. Lenovo has been doing somehting similar w/ their laptops for years. It never charges the battery past like 97%, and when it does reach the top it stops charging until it falls below like 92 then recharges. HTC needs to loook out for the battery they already have enough flak from all of us for the last few years w/ every touch device they have had. We want more life, and they are giving it to us, just wish they could figure something out like lenovo, let it go down to mayeb 94 then charge up again perhaps.
it really isn't true, mine dumps 10% or so off the charger regardless of if it has been on the charger all night or 2 seconds after it turns green.
So I've done the:
1 charge to green
2 unplug
3 turn off
4 charge while turned off.....to green again.
And here are my honest results.
Boom........phone has 20% left after 16.5 hrs of moderate use (calling time total 1 hrs talk total, surf /post 1 hour total, load up 5 apps from the market, listen to audio clips on the speaker phone for almost an hour straight, podcast this morning for 30 min...and other randomness)
And still have 20% left. Going since 6:30 a to 10:30 p...........approximately 16 hrs equals 80% so about 3.2 hrs left to use before dead.
THIS EQUALS APPROX 19.2 HOURS OF MODERATE USE BEFORE RECHARGE NEEDED.
eat it Apple 4G . You can't even reliablly make calls let alone last that long without charging. My 3g never lasted that long. You still need a wall Apple we are truly mobile. If I was on the road I could (don't need to just yet) swap out for another battery.
I'm loving xda for all their brains helping me get the most out of this phone. Thanks to all.
Sent from my HTC EVO 4G using the XDA App.
The point here is that we shouldn't have to do the "charger circle jerk" to have 100% battery. I should be able to unplug it and have a full battery. Not 90%. I might need that 10% later on today, its accomplishing nothing sitting on my nightstand.
If the battery is toast after a year instead of a year and half, i don't care. I want a fully battery, not an almost full battery.

HTC advised a similar solution to the battery issue. I did this a few times and my battery lasted more than 15 hours with moderate use. Here's the post:

My phone used to do this, even after i followed all the little tips and tricks of playing hide and go seek with the charging cable and my phone.
Know how i solved it?
Bought one of those $10 Ebay 2 1500mAh TP2 Battery And Wall Charger bundles, now i dont use the OEM charger at all, the cable turned into a permanent USB cable on my comp and never sees the actual HTC charging unit it plugs into for AC power. I have 3 batteries and i rotate them in that little wall charger which actually charges them to 100%. Its also proven because if you take one of the batteries, put them in the phone and charge them until the green light comes on, supposedly to "100%" and then take the actual battery out and put it in the ebay wall charger, it will still charge for another 15-25 minutes. Charging it in the phone, as soon as i unplug, it almost instantly always drops to 90%... charging with the ebay wall charger, it will stay at 100% for a while before it falls off.
Below is the link to my thread which contains linkage, pics and info about the ebay bundle, others also claim the same issues and fixes in my thread. I mean for $10 bucks, does it really matter if it works for you or not? Its worth the shot and for me, it was a great investment.
Best of luck.

I did this last night and I'm at 14 hrs and 57% left. If I have to charge like this to get great battery life that's fine. My iPhone 3gs would last half a day. So this is blowing it out of the water. And I can hold it with my left hand to talk.

Good stuff man, I finally just switched batteries after 21 hours.
i just got this battery and did the initial 8hour charge... but im seeing that once i take it out of the plug, battery monitor says it starts at 100% and then after 15 minutes drops to 86%....
is this bad reading from the program? or did i get a defective battery?

Are you using an external battery charger or are you charging through your phone? I do not have one of these batteries but I'm under the impression that the EVO firmware will only allow a charge of 4.15v which would be far below the requirments of a 3500mAh battery.
If you have an external charger and that is what you are using.... I would say your battery is defective. Contact the manufacture for recommendations.
No, I am using the phone to charge....is this a hardware limitation or is there a patch for this?

Seido website says to charge until your phone shows 100% then leave on the charger for 2-3 addtional hours.
Even then I would think an external battery charger would be the route to take to unleash the full potential of the 3500mAh battery.
Keep me posted because I was thinking of buying one of those. But if you have to remove the battery to fully charge it then that would be a deal breaker for me.

I didn't have to use an external charger. The first charge I let go overnight. After 4-5 charge cycles the percentage drop was much more normal for that first 15 minutes, and of course after that the battery lasts forever at idle. I generally get 10-15 hours of heavy use (couple hours of streaming movies/music, texts, websurfing, some video conferencing, that kinda stuff), 20-30 moderate, and 40 with minimal usage.

The Evo cant charge this battery properly. The only way to get a proper charge is in a wall charger. Don't get me started. Look in the other 3500 thread for all you seek.

in order to get full charge FROM any battery related to the evo, you will have to remove from phone.... something in the evo whether it be software or hardware doesnt allow us to charge more than 1500 (really 1400 +/- mah) back into the battery. Dont ask me why but it just is that way...sucks i know

you're actually cheating yourself and making your phone bulkier for no reason at all. WHile that 10-15 hours of heavy usage may be good...... if you actually think about the charging scheme.... you can do the same thing on the 1500 mah battery LOL
so while you THINK you are charging the battery after your light turns green on your phone, you are not. Your phone thinks the battery is still the 1500 mah battery so that is all it is charging. (yea... you got a bulkier phone and those other 1500mah arent being used/charged #fail)
I know so, cuz you said your battery percentage drops for the first 15 minutes.... with my seidio 3500 mah fully charged into the wall.... i leave the screen on for at least an hour and my battery is still a full 98% if not 99%
wall charger makes a world of difference, talking night and day.
im on my phone ALOT... i keep wifi and everything else on... with a wall charged battery, i see an easy 24 hours + !!!!! Sometimes i say to myself "why wont this damn thing die!!!!!!!!!!!!" no bull lol

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.
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.
I ordered the HTC extended battery for my TBolt, but I'd love to keep the stock battery in a pouch on my work belt and just kinda forget about it in case a situation arises where I need it. Any idea how long it'll hold the charge?
It will discharge over a certain period of time. Not sure if its days or what, but it will.
Your best bet would be to buy a spare battery charger on eBay or something
It will very slowly discharge over time, but certainly not days, and unlikely even weeks. I have spare batteries for my Droid I've left out a couple months at a time and when I finally slapped them in my Droid they were still at 100% charge.
just don't let the spare become too hot, or that will drain it faster.
It depends on how your storing them also. Keep them out of the cold or extreme heat and it should hold its charge for a couple months.
Another piece of advice if you get a spare battery charger, don't leave the battery mounted into the charger after its charged up if it isn't plugged in. might just be the cheap one I have but if I do that it drains the battery overnight

A charged LiIon battery will hold a charge for years.
Keep it stored in a cold place, away from heat. Heat and the full charge will oxidize the battery and it will lose capacity, (though still hold a charge).
Basically, never keep it in a hot car.
Storing it in a cold refrigerator is a great idea, but warm it up before you use it.
i use my spares about once a month. after a month of no use, they are still at like 95%.
If you where to place it some where or carry it it usually losses about 10% to 15% a day I always bring the extra battery where ever I go. Also a good thing to know that powering the phone up can take 10% from the battery when powering up.

Lithium Ion batteries we use in our phones don't discharge that fast when not in use, unless the battery is bad. Normal discharge on them is around 1% a month or less. If you're storing a battery for a long time, you'd be better off not storing it at 100% charge though, can cause damage to them over the long term.
That being said, my stock battery is in my bag with about an 80-85% charge on it, I only use it in case of emergencies (I'm never away from a charger longer than that 85% will cover, so works well for me).

No way they lose that much.
I have an old Windows mobile phone that has not been turned on since last year. I just turned it on to check it, and the battery is at 60%. No idea what it was when I turned it off, but likely not 100%.
LiIon does NOT lose but just a percent or two a month. Store your spare batteries in a cold place like a refrigerator, and they will last with a charge longer then you have the device.
