So like everyone else my battery life sucks. No big deal. I bought the extended battery from Sprint, and I can see the battery diminish in front of my eyes. I mean dropping 1 percent per minute. Is there a way to test the phone to see if it is the culprit?

ther are lots of ways to check things. does it drop 1% a minute all the time meaning you only get 100 minutes? does it only do it when you take it off the charger at 100% where ti will drop to any where from 99-90% in a matter of minutes?
if the later then thats normal and is because the phone doesnt have a trickle charge. this means that the phone charges your battery to 100% then stops however the indicator on the phone will not change it will still show 100% once the acctual power reaches 90% the phone then charges again up to 100%. what this means is once you take your phone off the pwoer if it has been sitting there even if it says it is at 1005 it can be any where from 90-100% which the battery quickly changes to over first few minutes.
If it happens past 90% and all the time then something is wrong and you likely have at least 1 if not more apps running wild on you, you have things set to sync constantly, and you have everything under the sun turned on for your phone.
for apps the paid version of system panel is very nice for monitoring you can go to monitor top and top apps and see which apps are using the most battery/cpu.
witht he information you have given that is aobut the best i can tell you. I would not say everyone has crappy battery life with the evo as i have slowly gotten my phone set up and now with moderate usage i can get 14-15 hours and at least 8-10 with very heavy usage(stock battery) which i dont consider to be crappy battery life.
I appreciate the response, and I forgot to add that I'm running stock unrooted sense. This is not my first Android phone so I know about battery managing. I don't have everything sync every two minutes nor do I have everything turned on. It does drop rather quick even past 90 percent. I think it might be the phone it self. I doubt I got 2 bad batteries, one being extended. I'll see if I could get a device swapped out.

My first EVO was like that. It drained quickly shortly after charging. I could never figure it out. Till one night before going to bed, I noticed something weird about the bottom keys on the phone. They were " very dimmly " lit. The home, menu, return, search were all dimmly lit. It was I believe a defect in the phone. I got it swapped out. No problems like the 1% drain since then.
I have purchesed HD7 4 days ago. It never charges 100% even if i leave it on charge for whole night.
Any solution.
how do you know it doesn't? the battery icon isn't exactly specific? but if it doesn't, take it back to the store you bought it from.
The phone stops charging before 100%
Just like other phones it has battery indicator in the form of cell/battery.
It should appears filled/full when charging is full and as the battery drains it should gradually appears empty. Now the issue is that it never appears full. The extreme right side of the cell/battery always stays/shows empty.
In other words we can say that the phone stops charging before 100%.
Beside this the indicator works fine and the battery life is also ok.
I bought this phone in UK and currently working in dubai so I cannot take it back to the store.
This happened to me, for the past week+ (I bought the phone on 28th).
I don't know why but an Overnight Charge didn't seem to be long enough for it to charge fully, it was always nearly charged.
However, This morning it seems to have charged 100% so maybe it's just a matter of time? Maybe the battery isn't in sync or something when you first buy it.
Think the battery icon is a bit dodge. As long as you get the green indicator light you know it's fully charged. If it's still orange then still needs topping up.
I've not had a problem charging myself but what I have found is that sometime the indicator says it's nearly dead. Reboot and sudenly there is an increase in amount of battery left. Very odd.
Maybe you need to wait a few weeks just to let it settle.

That isn't acceptable for obvious reasons, so I hope that isn't the case.
P.S. 14-30 day return/exchange policies.
All right Dudes!
The problem is fixed. Simply fully charge your mobile phone and then full discharge till it turns off by its own. Repeat the procedure three times and you are done.
Good Luck
I have the same issue, if you turn the phone off and back on when the light turns green, the battery icon is then full.
So seems like a software issue to me.
My HD7 is going back tommorow anyway, keeps resetting itself and when trying to video in 720p it looses focus!
I previously went back to O2 store the day after i bought the phone about the original charging issue. They were going to swap the phone but then had no stock. Then my above issues topped it today so took it back and surprise surprise they were out of stock! Apparantly expecting a delivery tommorow but they don't know what they receive till they get it (BS i reckon) so if they don't have any in tommorow I'm getting a refund and going to go for a Venue Pro or just stick with WM 6.5..

How do you "full discharge" the phone? Use it until the battery is complete dead and charge it up again x3?
Yes, use it till battery is fully dead and charge till charging light turns green.
That never worked for me either, infact last night when the phone was flat, I have left it on charge over night and it went green, but showing about 50% charge, turned it off and back on and its then full.
My phone is doing this as well, now. Charges to full on teh charger. Take it off, adn it goes straight to 75% charge - viewable in the Battery Saver by battery level. It's impossible to charge it fully, and battery life is TTEERRRRIIBBLLEE.
Either something is wrong with the phone or firmware, or the OS. Not sure. But I can't use the phone like this. It's as if it has a 920 mAh battery in it. Obviously that shouldn't require anymore explanation.

Follow-Up: I'm convinced it's a bug in the WP7 OS. When you charge to full, and take it off the charger, it instantly drops to 75%, then if you put it back on the charger 20 minutes later it goes to 93%?!
Problem is, the OS is set to shut down service, etc. when battery power is low (even beyond the battery saver setting, IIRC), so the bad information the OS has can hamper usability. It's basically cutting 2 hours off your battery life when you unplug the phone after a full night/day's charge.

And kill the battery, forgot to say.
Charge on the wall charger, not PC USB.
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.
Problem:
I have been reading as many posts as possible but I haven't come across my exact situation. I apologize if this is posted elsewhere.
I am running a rooted Dinc using CyanogenMod 7.0.3. If I charge the phone while it's powered on, the amber led turns green as soon as the battery indicator hits 100%. However, recently I've noticed that if the battery is close to being full, say 90%, and i power it off to charge it, it actually takes longer for the amber led to turn green. It might take 20-30 minutes longer.
I've also noticed the amber light turn green when the indicator only showed 92%. In trying something different I also noticed that if I charge the phone while it's powered on, then turn the phone off, the led goes amber and takes another 20 minutes to turn green again (I might be accidentally bump charging in this example but I'm not sure).
Attempted Solution:
I've read that a battery recalibration might help. I tried one method that requires the battery to be pulled after a full charge, but my phone won't boot while plugged into the wall if there's no battery. Then I tried booting into recovery, where I found an option to reset the battery stats... which I just did about 5 minutes ago.
I'm going to see how things go tomorrow, but is this normal? Has anyone else experienced these things? Thanks.

The kernel and the hardware charge it in different ways. That's why there are differences. DInc is famous for ending charging before the battery reads full. There's already a thread on that. there's not much point in getting hung up on how that thing charges. Be glad yours isn't like mine; a battery that discharges faster than it charges. Seriously.

Before I had a fast charge kernel (thanks Chad!) Using GPS with the stock VZW car charger, my battery would go down while it was on the charger!

On AOSP roms, the LED will turn green at 90% and charge slower from 90%-100%. Perfectly normal, and I think on any rom it will charge slowly from 90%-100% to protect the battery.
The battery will charge further when you turn the phone off, what you described is what's known as bump charging. If you do this, you should notice a slower drop from 100%-90% than usual, because the battery is charged to a "true" 100%. When the phone is on and charging (above 90%), it simply keeps the battery above 90% even if it says it's fully charged, and this is why the inc is notorious for the quick 100%-90% drop.
If you do a bump charge and then clear the battery stats and use the battery calibration app will you need to bump charge again or will it know what the true 100% capacity is and keep the droid lasting longer. Not noticing much of a diffrence when i went from 1300 battery to a 1500. May get a bigger batter that'll fit the stock battery door cause I'm trying to get the best battery life i can get.
Thanks guys, I appreciate the help. I think something else that has thrown me off is that before I rooted the phone I wasn't able to see the actual battery percentage in numbers... all I could see was the battery icon. Things are now making more sense.
After recalibrating my battery I bump charged the other day and I was able to get almost 2 days out of my phone on light usage. Without bumping, I was able to end my day yesterday at 50% under my normal usage. Which is a noticeable improvement. Normally I end the day with about 10-20%. The big test will be once I go back to work next week. The cell reception is real spotty in my classroom, which I know makes the cell radio work harder.
Thanks again.
I found a lot of answers I was having about battery charging in this thread:
Your battery gauge is lying to you (and it's not such a bad thing)
I just purchased a used Galaxy S3 and have had it for a couple of days already. This is what my normal charging routine is with any phone I have owned:
I shut the phone off before I go to sleep at night (usually around 11:00 pm) and plug it in. I'll get up at 6:00 am, unplug it and turn it back on. I've noticed though that with my new phone for the past 2 mornings, the red LED light is still on when I unplug it and when I turn the phone on, I immediately check the battery status and it has only charged as high as 92%. I am using the original wall plug (5V-1A) but the usb cable is not original. I also tried using 2 different ones with the same results. I'm just wondering what the problem could be and if anyone else has had this issue and what they have done to correct it? Thanks...
Try to reset the battery in CMW
Sorry, I should have also mentioned that the phone is bone stock for now...
Soooo, last night I tried a third micro usb cable and I drained the battery all the way down to the point where the phone shut itself off. I then plugged it in for the night and the charging light was finally green this morning. However when I turned the phone on, the percentage still only showed that it was at 92%. I'm not sure what else to try and who knows, could the battery be borked?
How long does the battery last? Just because the battery meter says 92% doesn't mean its not full, it could just be calibrated incorrectly. Put another way, as far as the OS know 92% is as far as the battery charges even thought the battery is at maximum capacity. Unfortunately im not sure if there is way to reset the battery meter without root access.
Yesterday the battery lasted a little over 16 hrs. That's with mobile data shut off, gps off, bluetooth off and pretty much everything else. I sent a hand full of texts, around 3 hours of wifi usage and about an hour of music. I can't really think of anything else I used it for...
If you are getting 16 hours on a stock battery there isn't anything wrong with it :good:. If the calibration of the battery meter bugs you enough you can always root it and reset the battery stats, either from CWM recovery or with a capable app. I have SD Maid which can do this with root access, but im not sure if the feature is available in the free version. Im sure there are other apps on the market that can do this as well, possibly free ones, but im almost certain they will require root to do so. If you do, charger the battery overnight to ensure a full charge, if possible use a usb power source instead of the wall adapter. This is a slower charge and actually can achieve a fuller battery charge. As soon as you remove the phone from the charger reset the stats and let it run down to nearly dead, i would probably do this twice to give the battery meter a good high/low limit.
Thanks! I will try this once I've exhausted all other possibilities that may be causing this. It does bother me a bit I'm not sure why. Maybe my OCD kicking in lol! I've just pulled the back cover off and the battery in it is 3.8V and 7.98Wh. The model number of it I believe is GB/T18287-2000 and below that it also shows 4.35V. Can anyone confirm if this is even the correct battery in it for this phone? Thanks...
That is the correct voltage and wattage....so yes it is the correct battery.
Thank you...
So another morning went by with the same issue and i figured i had to try something else. I went into The Source after work and went ahead and purchased the extra battery kit they sell (comes with the battery and a battery charger/stand) making sure that i could return it if it turned out that it didnt solve my problem. So i took my old battery out of the phone and when i turned it over i noticed a dent and a crease running down one side of it (probably the culprit). I put the new battery in, plugged the phone in and a little while later i got a green light and a 100% battery status! I was worried that there was something actually wrong with the phone but a $50 gamble later and im good to go. Oh i also tried charging the old battery in the charger but it would not finish the charging cycle (wouldnt go green after 3 hrs in it and the battery according to my phone was at 80% when i took it out).

Yikes! Lucky you noticed this before it turned into a big problem. With visible physical damage to that extent i would say the chances of that battery causing some serious damage is high, especially if it had went unnoticed and was used for extended periods of time. I would contact Samsung as they should replace the battery under warranty if the battery was in that condition coming out of the box.
See thats the thing. I bought the phone used and the issue was there since day one of owning it. Since these phones havent been out for a year yet, there should still be some kind of warranty on it and i guess it wouldnt hurt to try contacting samsung about it. Who knows, i could get a spare battery out of the whole thing.

My only problem with that is who knows how it got that way, if it didnt ship from the factory in that condition Samsung shouldn't be held responsible.
True but how in the world could someone do that on purpose? The condition of the phone itself is about a 9/10. Unless they took it out for who knows what reason and dropped it and whatever else. I'll never know. Maybe i will just leave it alone. Everything is back to the way it should be...
