I have 2 extended batteries, one is 2200mAh and the other one is 2400mAh. They both drain very fast unless they are charged using an external charger. I was just wondering if anyone else was having draining issues as well.

I personally believe that the algorithm used to determine charge capacity is inaccurate. I have a 3500 mah battery and I have to go through a series of charging maneuvers to get it to charge completely. Once it is charged fully, the battery life is outstanding. But if I simply disconnect when the LED turned green, without my maneuvering, it "appears" to drain fairly quickly.

I have the same exact problem. Do you think an update in the firmware could possibly fix this problem if it were brought to HTC/Sprint's attention

It would need to be more than 1 person complaining to get that kind of result. id by chance you're on PRL&NV 1.90, try downgrading to 1.77, as many users see better battery life on 1.77 over 1.90.

If the battery drain you see is the INITIAL drain this is to be expected. Your phone will drop to about 92% or so in the first 10 minutes. After that it should be smooth sailing

Can you define maneuvers?
I have a 3500 mah battery too. I usually leave it on the charger for a good 90-120 minutes after the green light is lit. Once the waveform in the batt monitor widget has stabilized to one resembling a sawtooth wave (/\/\/\/\/\/) with identical amplitudes, I consider it done. I followup by shutting the phone down, waiting til the amber light is green again, then unplugging/booting up.
Depending on the amount of use during the previous off charger time, rebooting it keeps the os from slowing down.

That's what happens but not around 90% its more around 70% then it last for about 8 hours

I have a 3000mah battery and I use battery snap to monitor volts and remaining time left on battery. The battery status could say 100% but I look at the volts. If it says 100% but only 3.991 Volts for example then I know my battery isn't fully charged and within 10min it will be at 88% . But when my volts say 4.204 volts then I know it's truly at 100% and battery life is great . So I suggest check the voltage before unplugging.

ive read lots of threads about the battery on the evo, its natural for it to drop from 100% to 90% within the first 10 min, something about the evo not charging the battery fully to help preserve the battery or something, there is some steps you can do to charge the abttery fully, but that invloves turning it off, plugging, unplugging, etc... personally i use an external battery charger, and 2 batteries, it seems to charge the battery better, and it doesnt seem to drop that 10% so quickly, it still drops faster then it should, but it seems to stick a little longer, but after it drops that 10% it stabalizes and drops a lot slower, u can pickup batteries and chargers cheap

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

Very doubtful. Your best best is the kernel being developed in the dev section with increased charging.
My question has nothing to do with the phone itself because the battery is not in the phone when its charging, it's sitting in the cradle. Nothing to do with the phone itself. Do you think the cradle will charge the battery fully and completely.

I've got the charger mentioned as well. I just see it charge the battery "normally" to 100%, and if needed over the next ~xx(x) hours or so, another trickle at low mA will be applied. That isn't the same as this "bump charge" that is always referred to here.
If you turn the phone off and charge, it'll charge just like the charger (Seido) to 100%.
There's lot of good info about LI batteries like this writeup: http://batteryuniversity.com/index.php/learn/article/charging_lithium_ion_batteries
Anyway: I thought the main gripe about the DINC charging technique is not anything about the technique, but that it always runs the phone off the battery, rather than using the USB current when it's plugged in. Most phones use the USB (or whatever tech) to a) charge the battery and b) run the phone. Of course if this is HTC's method, then you'll very rarely unplug at 100%.
The rate of battery consumption, regardless of % starting point is more of an issue for me. Using all the SENSE/HTC/VERIZON stuff is a losing proposition more than not having 1-9% of the full capacity at 'go' time. As soon as I rooted, I dumped every app and service starting with HTC*, VER*, *sense* and battery life improved by a great deal. Yeah, I don't care about social networking (well, aside from a forum or two ) -- But I enjoy most of the other phone functionality.
The charger's fine, it's the battery that troubles me
I have the charger, too. Works fine. Does not require "bump."
But the battery (the 1750) that came with it has failed to impress me much, with a tendency to overheat. Frankly, since I rooted and started using SetCPU to underclock with screen off, I've been using the stock battery.
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?

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.

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

1.) Plugging in the phone while charged does decrease the battery life as you can only charge a battery for lets say 1000 cycles or so.
2.) Battery life depends on how long you use your phone, your ROM so I couldn't say. But my phone with the screen on lasts about 8 hours (SGH-T989)
3.) Check the reviews, it has five stars so I would assume that the battery is pretty good.

Not at all. I would use a battery monitor app to see what's draining the battery because that's very excessive drainage.
I can't imagine how much it drains when you're actually using it...
what rom/kernel are you using?
I agree with what others here have said, but just to add a little something, I heard that for the best battery "life" its best to try and keep it between 20% to 90%. Don't quote me, I heard it on one of those YouTube tech channels, I wonder if that is true. I always thought that it was best to completely kill the battery and then fully charge it.

I do it when I can't get a full charge before bed; but I also wake up 2-3 times per night and tend to unplug it once I notice it's at 100%. I've read that once it reaches 100%, if it stays on charge for a certain amount of time it will switch to battery and drain, then charge back to 100% after a certain percentage is drained. I would say that's the case as I woke up one morning and the phone was at 92% charge and was in the process of charging. Battery info said it was charging on AC and the graph showed it went to 100% then back down.

Hmm that's weird, but from the sounds of that, I don't think it's healthy for the battery to charge for a long time

Sounds like Google services are using your phone at night. That happens to s lot of people but can be stopped if you follow the battery life thread that skipjacks started.

That thread is perfect! I would use it but I need notifications to notify me but I did use it for a night! Amazing difference

I do use that guide. My signal is terrible and is what drains my battery. I really don't believe that is related to any app running wild and draining my battery because from completely dead to 100% takes about 2.5-3 hours with me using it, WiFi on, brightness at 100%, etc; I can also easily get over 2 days without a charge with light use... It would be more but my lack of signal accounts for an almost 1.5% per hour idle drain. Good signal areas I'll drain less than .5% per hour with no use/app changes outside of having a strong signal.
Weird...
When your phone charges to 100%, your phone knows to stop charging, mine always stops charging when is says "reached 100%". I just leave it on the charger and it stays steady at 100 until i take it off.
It shouldn't effect the lithium ion, either.
I thought that was the special thing about lithium ion?
They don't wear down?
Idk, could be wrong.

Overnight charging is a no no. More info here http://batteryuniversity.com/learn/article/charging_lithium_ion_batteries
I always leave it charging when I fall asleep. And if, IF I wake up in the middle of my sleep and see that it's at 100% I'll unplug it. If I don't wake-up I'll just leave it charging until I wake up. Been doing that since before I even had a smartphone and never had any problems. Then again I do switch phones every year

A bad signal will definitely drain your battery. When I know I am in an area without signal and will be there for a few hours I turn my phone's power off so I have some battery left when I need it.

I've always charged my phone at night and have never had usages with the battery.

Bought some cheap batteries on Amazon, I charge whenever I want, however I want (typically overnight, all night). If I ruin the battery, so be it, I can just pop it out and replace it in 5 seconds. This is the real advantage of having a removable battery.
I've always left my smartphones on the charger overnight. Seven years going and haven't had any issues. I do tend to replace my battery after 9-12 months of use though.

This sums it up. Per the article linked earlier in the thread about charging li-ion, it sounds (relatively) trivial for the device manufacturer to implement a charging cut-off after the cells reach a specific voltage level. Once the cells drop to a certain level they're safe to charge again, and the cycle starts over. I don't imagine it's great for the battery to sit on that recharge cycle, but it's not going to over-charge and become a fire hazard.
I imagine external battery chargers might be a little different. That $3 battery & charger from eBay isn't going to have the same safety regulations as a major manufacturer like Samsung.

An interesting tidbit from that article.
Li-ion does not need to be fully charged, as is the case with lead acid, nor is it desirable to do so. In fact, it is better not to fully charge, because high voltages stresses the battery.

I'm pretty sure a $600 phone can handle any of your charging blunders. Relax kid.
We're not dealing with Nokia's anymore.

Avoiding full charge has benefits, and some manufacturers set the charge threshold lower on purpose to prolong battery life.
Lithium-ion does not need to be fully charged; a partial charge is better.

I get the general concepts that the article presents, but it doesn't really address any advances in charging methodologies that newer devices could add. It reads like it was designed for 'dumb' devices such as cordless phones, rechargable power tools, etc. For instance, it says never to charge with the device powered on. Yet Windows Phones (at least my Lumia 800) won't charge with the device off...plugging it in automatically boots the phone up.
Our phones obviously have more advanced power circuitry, such as being able to hold the power button in and have the device power cycle no matter what state the phone is in, and I assume it applies to other parts of the phone as well.
