I thought I would bring some info I highly pushed with the Thunderbolt and Evo 4G that applies here. IF YOU HAVE THE EXTENDED BATTERY, YOU WILL WANT TO DO THIS SO YOUR PHONE UTILIZES THE ENTIRE EXTENDED BATTERY. The phone comes with a smaller battery, so it's batterystats.bin file is set to see that battery. It may not charge your extended battery all the way as it will think it is done charging much sooner than it is. Not that you won't get longer battery life without doing this, but you can always get MOAR!
**Disclaimer**I am not responsible for anything you do to your phone, zombie apocalypse, or the fact your phone called your girl/guy at the wrong time**As always your mileage will vary, some phones work better than others**
This is a form of bump charging your phones. I used it today, and noticed beyond better battery life immediately. So let us get down to business.
[Step 1] You will need to plug the phone into your charger, and charge the phone until the Notification light turns green.
[Step 2] Unplug the charger, wait for the green light to go out, plug the charger back in and wait for the light to turn green again. Upon doing so, turn the phone off. You will need to have fast boot OFF.
[Step 3] Once the phone is off, wait for the light to turn green, and unplug your charger, wait for the green light to go out, and plug back in. Repeat this step for a total of 10 unplug, plug back ins. Don't panick if sometimes it takes much longer than other times to turn green. You are charging the battery past the "capacity" that batterystats.bin says the battery has, which we will come back to in a min. Power on your phone. If you do not, or cannot temp root skip step 4
[Step 4] If you are able to temp root, then you can make your battery even better. Using a root explorer, go to data/system/ and delete the file batterystats.bin and reboot your phone. DO NOT use any battery calibration apps from the market, and down the road when we get S-OFF Clockwork Mod to wipe the battery stats. There is a known issue with CWM where it doesn't work, and I have tested a few calibration apps that say they delete batterystats.bin, but the file is always there, with the same data in it after using the app. Only way I have seen that works is manually deleting it.
[Step 5] The Hardest part of all. Use your phone, do not plug the phone in once, until it hits the 15% mark and asks you to. Once you do plug it into charge, let it charge all the way back up. You are building the batterystats.bin file so it understands how much charge your battery can actually hold. FUTURE REFERENCE: you will need to do this everytime you factory reset the phone, everytime you flash a new rom, etc. I know we cannot do all this currently, but this guide will still provide usefulness down the road when we get S-OFF as you will want to calibrate the battery the same way.
****If there is anything you noticed i put in wrong, or questions let me know***HTC has supported this method, minus deleting batterystats on many of their phones, and yet again seems to work on the rezound as well.****
Or you could just download the free battery monitor widget by 3c and you will notice your green light turn on at "100%" but keep an eye on the mA being pushed into the phone. When the mA goes from a positive (green number) to a negative (red number) that's when you should unplug. You will notice that your rezound "thinks" its 100% about 10-25 min before it really is... Much easier than feeling tweeked out, plugging and unplugging multiple times. Just another option. Good post though for sure. As most would NOT benefit from the full extended potential the battery has to offer.

when the mA goes red though, is based off the batterstats.bin file. I was not even talking about when to unplug the phone. I am talking about allowing the android OS to see how battery it actually has to use. so you are talking about something different than I am.
**edit** wanted to add. Your phone hitting 100% may in all reality only be hitting say 95% for example, but your phone thinks it is 100% hence why you can turn your phone off when at 100% and it continues to charge.

haha read it now. Was unaware that the rezound knew to keep charging. The Tbolt never did(atleast in the beginning as i stopped using it for awhile), and the Evo 4G never did either. I never thought to check this as HTC themselves never made mention of it charging past "100%" on its own.

Stupid phones! Just give us a bad ass device that's unlocked, so we can do what we want already! The majority of people with these devices have no clue of their potential anyway. I work for vzw Btw and just deleted all my pics of the Samsung "Fixthis" over rated and cheap feeling like all other Sammy's IMO. I'm keeping my rezound no matter what. Even though Chingy hooked my Tbolt up with mad unreleased ish. I just switch my sim back n forth as needed

I did the battery stats fix with my Inc a long time ago. When I popped on the Rezound extended battery I plugged in the charger and it took 4 hours to charge vs about 1 for the original. Now at the end of a full day I have about 70% left, so I'm pretty sure the Rezound is much better about figuring out battery stats then older HTC's. IMHO. I'd love to see some data to back me up though.

So, step 2 turn the phone off at the end. after step 3. u say to reboot?? so if the phone is already off.. u mean to turn it on. then turn it off? kinda doesnt make any sense. Unless by reboot, you mean to just simply turn the phone on. in which, u should probably word it "Power Up" not reboot.
so confused lol
Lithium batteries are charged by monitoring voltage first. The phone can monitor the mAh going in and out, but it really has no bearing on the charging. It does allow the phone to monitor the health of the battery by watching for capacity changes as it ages.
Bump charging gives a slight overcharge, this is why the battery lasts a little longer. Charging with the phone off is best for calibrating the battery stats and for battery life because the phone can actually fully charge the battery. It is not possible to fully charge the battery when the phone is powered on as the battery is in use.
Here is a link to a post I made about lithium type batteries and how they charge and the reasons for calibration. It should clear up some things about the batteries.
You can do a bit of a bump charge by charging the battery with the phone off, then when the LED turns green, pull the charger and let the battery settle a few minutes then plug it back in. The LED should not be green and it will charge at the fast constant voltage rate for a bit more. Let it charge about another hour then unplug, wait a few minutes and re-plug it in again. This can force in a few extra mAh.

I'll be honest I haven't looked at exactly how much of a change it results on the Rezound, but on the Evo 4G for example, we got more than a "few" extra mAh. I am glad to see someone agree with me, to an extent. I will say the way I listed it is the way provided by HTC back when the Evo came out. What you said to do, we tried with the Evo 4G and it didn't work quite as well. Maybe that is why you say only a few mAh.
The one thing I have missed from my Evo 4G days are the trickle charge kernels. I know everyone thought they were bad, but no one ever had real proof of them damaging a phone, hell I used trickle charging kernels only for well over a month everyday and never had any issues. I would love to see those come to the Rezound.
I did every trick in the book to increase battery life in my Droid Charge (bump charge, deleting batterstats.bin etc etc etc) .
I stream audio all day at work from either iheart radio or sirius online & that absolutely KILLS battery life. My Charge would kill a 3500 extended battery before the end of a long work day.
Now, I am getting awesome battery life from the 2750 extended battery on the Rezound. I bought two of the 2750 batteries with the phone as they where only $29 each at the time with the extended back.
I did no tricks at all other than fully charge and let it run down to about 2% a couple times. I have been using this phone the exact same way as the Charge & I have yet to go to the second battery. I stream all day & its still running when I walk in the house at the end of a LONG work day.

Good lord, am I the only one that doesn't look at their phone while it's charging? I prefer to be asleep and let it suck as much power as it can. I will try your method, but you might want to mention to use the stock charger, since it's been my experience that it's the only thing that actually charges the phone properly.

Well that is because the charger that comes with the phone is 1 amp, versus the charger say I bought to use in my car is about half an amp. Cause it was meant for older phones. same as using USB. USB will take forever to charge your phone.

4g.
I'm totally amazed at the battery life I'm getting. The reason I bought two extended batteries was because I figured I needed them.
I have had a ton of phones and not one of them could stream audio for 10hours straight, I don't care what battery you used.
Today, I went to work at around 8 am. I streamed both iheart radio and Sirius radio online for almost the entire day. When I got home around 6 pm it was running on fumes, but it hadn't shut down yet.
If I didn't stream anything it would run for days I think.

I don't understand why I'm getting so much battery life on this phone. It's exceeding expectations. Not that I'm complaining, but my experiences simply are not jiving with the results found by reviews like Engadget's. I have the official extended battery which is 2750MAh, but I had a 35**MAh one for my Droid X and it died faster under the same use. Considering I never lose LTE signal at home/work, and everything I do over it at work is using LTE, I just can't fathom how this MOTHER-F***ING BEAST of an amazing phone lasts like 20% longer on a 30% smaller battery over my Droid X. (I'm not going by the battery life indicator, but purposely letting it die so I know for certain.)
Also, yes, I understand they were using stock battery in the reviews; but I used that the first few days before going back and picking up an extended battery @ half off normal price.
I love this thing, and I love HTC for having a 1% battery indicator on the stock device.
Oh, by the way; should I really plug it in at 15% remaining? I thought you were supposed to let it die when training new battery life?

Add a battery indicator widget; it goes in 1% increments. I'd LOVE it if you could have it show on the actual indicator on the notification bar, but I haven't found a way to do that; but I keep a battery life indicator on my main home screen, and yeah, 1% increments for the win.
For the past few days my battery has been charging to a max of 92%, whether or not I try unplugging the battery, leaving the phone on the charger, wiping battery stats, and doing all that I can to try to reset the battery stats.
Anyone have any idea?
UPDATE: My phone is still not charging past 92%, no matter how long I leave it on, or what I try to do to fix it. 4167mv max
I have a similar issue, it's been like that for a long time for me. What ROM/kernel are you running? It might fix it to completely drain it, charge it powered off, reinstall ROM/kernels when it is completely charged and reset battery.
Sent from my MB860 using xda premium
drain it until it shuts off and then charge it all the way to 100%.
I too was having this issue after going from cm7 week 5, to week 8. I did what others were recommending and charged to what showed 4200mv, pulled the battery while still plugged in, put battery back in then after it showed 5%, turned it back on and Viola, 100% battery. Try it.
its most effective if you know your battery is fully charged, power it down, pull the battery, while the battery is pulled plug it into the power adapter, it will act like its starting to charge, but then instead of having a percentage, it will have a question mark. pull the power, put the battery back in, turn on, wipe battery stats in recovery and run with it...

I just started having this issue and cant wait to try it thanks for the suggestions.
when this happend on mine all i did was keep using it and it fixed itself. i ran it down maybe to 20% before I got to charge it again and it slowly creeped back up to 100%. took about a week.
I've had the problem, and have run the solution more times that I can count. But nothing ever fixes it permanently. Everytime I run the battery low, the levels get all screwy again. Maybe my phone is just worse than everyone else's, but I had to just give up on it. Would love a permanent solution, but so long as I'm running this ROM (CM7), I doubt I'll ever find one.

I'm in the same situation as you are... I had this problem for a long time now (Guess it has something to do with excessive flashing...) and no matter what kind of solution I do (Wipe battery stats via recovery, re-calibrate the battery, pull the battery out while charging and replugging it) it returns after a day or two.
I want to check if it has something to do with the battery or the device, and if I will remember to do so, I will plug my spare battery for several day's run, but that is subjected to me leaving the comfort of my usual laziness....
Would love if there was a permanent solution as well, thou I doubt that too....
I've had the same problem on a number of different roms and at different times. I find that instead of mucking around wiping stats etc, it has always come good eventually for me.

Didn't really understand what you meant, did the battery percentage fixed by itself and gave you 100% at full charge on one day? out of the blue?
Or did you just got used to have less then 100% battery display?

First let the battery completely drain and the phone shut down by it self. Second step is to pull out the battery and leave it out for 10min, after that take a plastic bag and put the battery in it and place it in the freezer for 15min. after this palce the battery again in the mobile. make sure there is no any moisture on the battery. Then charge the phone without power on till 100%.
By following these steps this will made your battery to charge fully and more talk time

Um correct me if I'm wrong anyone, but doesn't cold kill the battery and shorten its life? I remember my mom always putting new batteries in the fridge and them only lasting a couple days compared to the ones left out that lasted a month or so with same use.

Haha, I got a good laugh out of this one -- you've got to be joking.
I've had this problem for a quite a while now with the Atrix and two different batteries. I've tried dozens of combination of resetting the battery stats, running the battery completely down, and powering up without the battery and hot swapping it in. The hot swap definitely allows me to finally recharge to 100%, but once I run it down again, the problem returns. I've learned to just live with the less than 100% reading -- battery still seems to last a full 24 hours for me.

That trick hasn't worked since nicad batteries in the 90s, and is a really bad idea with our Li-PO.
Drain the battery till the phone shuts off, charge back up while the phone is off.
If it still doesn't get to 100%, boot into CWM, wipe battery stats and power off the phone to let it charge again.
^^ I know it works because I've done this like 2 days ago, and many times before that.
I have had this issue as well for a very long time. I've tried the pull out, question mark, 5% thing and it usually only works for one cycle, then the next only goes to 97%, then the next to 93%, then 90%, and it continually goes down until I have to do it again. Hopefully a permanent fix can be found soon. I've tried clearing battery stats, draining it to 0%, then charging it fully. I've tried everything. As far as I'm concerned, there's no fix as of right now.

★ATTENTION! I FOUND THE FIX!★
Turn phone off and plug it in to a wall charger. Charge it until your notification light turns green, quickly tap the power button to check battery level. (Usually shows 90%) If the notification light turns on, but the battery indicator is not at 100%, unplug phone, take out battery and put it back in. Now plug your phone. It should be 100% now. For the final fix: go into "Android Recovery" and select "Mounts". Mount Your SD card and Emmc. Finally wipe battery stats. Reboot phone.
This method worked for me. I am 100% sure this is the fix for this problem. This has to be done every time you flash a new rom or when your phone freezes and you screw up calibration by pulling the battery while it is still on. BTW, this is my first post so don't be mean to me!

Satin worship, is that like old fashioned polyester worship?
Don't know what happened but the phone is fully charged, according to the charge thingy before boot. But I can't turn the phone on. It came on once this morning and said it had 4% then died. So I plugged it back into the charger and its still saying its charger. But when its charging I can't turn the phone on and once the screen times out I can't turn the screen back on. I have to unplug then plug back in. The cables are just fine. I've tested on 4 different cables and 3 charge wall ports

Can you get into CWM recovery? What ROM are you on?
I've noticed on ICS Roms that you can't power the phone on while it's charging like you can on TouchWiz Roms. I couldn't even press.the power.button to see how far it had gotten. It's like the power button is disabled when charging when turned off.
The only thing I could do was let it charge for a while then unplug it from the charger and it would power up.

That's what its doing. But no matter however long I leave it plugged in it still dies as soon as it boots up with a brief notice of a low battery. I changed out the battery and it still happens. As for cwm, ill have to check later. I'm watching a movie then probably going to bed. Ill mess with it tomorrow and see what I can figure out

Can you reboot recovery as soon as it boots up? If you can, flash http://dl.dropbox.com/u/2056318/update-template/bstats.zip to wipe your battery stats.
You don't need to flash anything to wipe your battery stats and furthermore wiping battery stats will do nothing to fix the issue. The stats file is simply a .txt file, the device does not decide that the battery is low based upon that...it reads the milliamp hour output of the battery itself. When the battery reaches that predetermined output level it shuts down to prevent over discharge and battery damage. It's similar to what you see in RC trucks and such when using LiPO batteries. They include a failsafe to prevent damage to the cells from over discharge. I would recommend trying a battery that you know is good (not just assume) get a cheapo off Ebay for a few bucks our try charging in an external charger OR if there is a US Cellular shop nearby they will swap a dead battery for a charged one. The mesmerize is obviously identical.
If all that were to fail try starting out with a fresh wipe and reinstall of your rom and kernel, there may be something funked up in there if you have "dirty" flashed at some point.
Just some thoughts...
I charged my phone during the night to 100% and used it for a bit this morning. I went to the beach for the day, and left my phone at home. Upon returning (roughly 5 hours later) my screen was stuck on the ATT splash.
I looked at my battery usage to see if anything strange had happened, and I was greeted with the attached image.
I am currently running stock ICS 4.0.3 from ATT. Rooted with Kernal version 3.0.35-Siyah-v3.4.2. I do have a lot of widgets on my home screen, but I have had this same setup for more than 2 weeks and nothing like this has ever happened before.
Pleas let me know if you need any more details. Any and all help is appreciated.

Download batery calibration app from market, charge until you get 4200mv, disconnect charge, calibrate then after succesful calibrate restart phone then dont shutdown until you get force shutdown.
If you cant get 4200mv, wait to the highest value then calibrate
Anyway your signals are very low, it will be drain battery rly fast, try make them highet and keep wifi shutdown

If you cant get 4200mv, wait to the highest value then calibrate
Anyway your signals are very low, it will be drain battery rly fast, try make them highet and keep wifi shutdown

Why does low signal strength quickly discharge the battery? Also does this explain for the gaps in the battery info or is it something else?
Our phones do not require battery calibration. Have you installed betterbatterystats, and watchdog? If not, install them and see if it happens again. I can tell you that it's not the official update that's the problem, as I had it installed for a few days. Almost gotta be a rogue app. You could also try switching kernels just to see if it helps.

Thanks but again, whats going on? If I have been using the same setup for more than 2 weeks, shouldn't an occurrence like this have already happened?
I had a similar incident today running stock 4.0.3. no root. Phone went black. Once I noticed it, I restarted it which it didn't want to do at first. Went to the battery stats and it looks similar to yours. Battery level showed about a 50% drop. Never had that happen before.
Well I am going to try the first suggestion and see if that helps. I'll report back later.
It seemed that the first option worked pretty well. I let my phone sit for 8hrs today, and the battery only discharged to 87%.

Probably kuz it didn't reboot. It looks like your phone rebooted quite a few times for whatever reason, back to back, possibly got stuck in some boot loops too. Id call it a fluke unless it happens again.
And there is no "calibrating" our battery. If you reboot at lower capacities it'll come back substantially lower and then correct itself slowly over time. Its just how our meter works (voltage reading vs mah counter)
Hi, I've got a quite common problem - battery drain. I'm not such a noob, so I understand the way how the battery drain works (I mean why does it happen). It happened after changing the sim card. My sim card stopped working at some moment, so I decided to change it. After that I noticed that my Droid does not turn on. I plugged it into a charger, it got charged normally to 100%. But the battery is draining now constantly. I Changed rom, I wiped all the data, I did even restore backup from march, when the device was 100% functional.
I'm afraid I can not have a replacement as it is rooted, and a repair is almost impossible (I live in Poland).
Any ideas? Maybe someone had similar issue?
PS I got smthing like 10h of standby. That sucks.
PPS It seems that the battery alone is ok, as the phone is heating (so it means that there is energy stored inside)
Have you tried calibrating the battery?

By what? Charging to full and then discharging to 0%? Yes, I did xD Smthing like 5 times this week
Wipe everything, clean install a rom, download a battery calibrator app from the market and let it charge to a 100% and then let it die to zero

As I said before, I already did that
But use the battery calibrator

Battery is calibrated. The problem is not here. The problem is that battery is drained and it seems that there are not many things left that could cause the drain. Please stop posting as I can see that you are not giving any new ideas.
your battery may be just degrading all of a sudden. does it die incredibly fast if you leave your phone in safe mode all day?
Yes, I tried safe mode, without success. It doesn't seem that battery is degrading, as the phone heats up (so the battery must have energy inside)

What temps we talking? Try temp monitor app also of its discharging improperly it will heat up. Get a app like gsam and have it record what rate it's discharging at, sounds like a bad bat though to be honest. EDIT just noticed your rooted. And that you don't want to replace because of jag options. I suggest of your up to it to open the phone and disconnect the battery for a while. Couldn't hurt.

About 35-40 Celcius.
Talking about the opening of the phone, this is someting that I want to avoid. I can do that, after nothing works. Any ideas what could happen?
I've noticed it's happened to me but closing out processes and hard rebooting the phone seems to have cleared that.
Quick Note:
go to settings, battery, and uncheck Fast boot, then shutdown and turn back on. Let me know how that goes.

nope. No effect
1. What rom, kernel, recovery, and radio are you using?
2. I understand you charged to 100 and then let drain to zero, but did you reset your battery stats in recovery?
3. Do you have GSam installed?
1. Tried Supercharged, stock dna, hatka supreme (or something like that),
recovery: CWM
kernels: Blackout, crampler
Radio: the new one xD (The one that came with v2.04)
2. I charged to 100 and drained. During that I changed roms, did factory reset etc.
3. Nope, I've used (and still use) wakelock detector. The GSam seems to provide less data.
After all these weeks the problem is still present. I hope someone can help.
A Suggestuions:
Try an older microusb lead and slow charge from a usb 2 port, sometimes a battery has trouble with a charge sticking - try slow things down and slow charge the phone see if that helps.
I tried even the netbook usb port (350mah), still no luck.

but did you try it when the phone was at 0% and make sure your not using the fast ports, also try slowing it down further if you have any dvd players etc they will only push out around 100 to 200 mah may be worth trying.
Bar that i think the battery is naffed, i would say underclock but if you have tried safe mode its safe to assume itts not going to help..
The only other thing i have heard of but never tried is to keep drain the phone completely and then charge constanly by mains for 2-3 days. if you have tried everything else may be worth a shot.
What app or apps are draining the battery and how much time does it take?
There are no apps draining. The most impact (htc battery app) has got phone idle and wifi. After turning off wifi nothing happens, taking out the sim or turning on airplane mode does not help either
