Got my rezound battery in a couple days ago and so far its not so good. Gave it a full charge out of the box and then bump charged it. Wiped battery stats and then ran it hard to drain it dead till the phone shut off. Recharged and bumped it again. It will hold at 100% for a good while during use but then drops drastically. Sitting doing nothing it dropped to 60% in about 2 hours. Then listening to music it went into around 20% in 45 minutes. Charged it overnight and today sitting doing nothing it was down to 30% in about 4 hours. Put it back on the charger now its only charging to 88% and stops. Am I doing something wrong here or is my battery a dud.
Update
after the charge to 88% I have used the crap out of my phone tonight and more over the last 4 hours. Surfing on WiFi, music, and running repeated benchmarks. The battery had sit for several hours off charge and dropped from 88 to 52% while sitting unused. Dropped from 52 to 35% over a few hours of music and 4g web browsing while driving my wife around shopping. After I got home and started using it stayed at 35% for over 2 hours of use and has dropped down from 35 to 28% in the last hour or so of continuous use. Seems like its holding a good charge, but just not reporting battery stats correctly.

I have had the Rezound battery for several months and at first it was reporting the battery accurately, a longer usage time, and no complaints. I would go down to about 5% and then I would charge it.
The last few months have been erratic. The battery could show anywhere from 15% to 25% then just shut off completely. This has become very frustrating and unreliable once I get under 30. I downloaded a battery calibration app that has proven to be worthless.
I was on vacation last week and found out something interesting. If I charge the battery to 100% then take it off for about 5 minutes and reboot the phone it will show that it is charged to somewhere between 79% and 84%. I can let it charge again to 100% and get a full charge that time. I tried several times doing battery calibration and it seems to make no difference. I think the default stats file is limiting the charge to the stock battery capacity somehow. I know the stats file gets written on boot and I found a post on here somewhere about HTC releasing an update for their extended battery after its release due to it not charging completely. I wonder if the rezound battery and all other extended batteries that aren't the capacity of the two official ones could perform better if they had modified stats files. Without the reboot and additional charge I am averaging 16 hours roughly per charge. With the additional charge I have gotten over 30 hours on one charge and get at least 23 hours. Last full charge was 27 hours 38 min and still had 16% charge.

Finally broke down and got one yesterday from Big Red. So far, on initial charge (off wall charger), I'm @ 38%, 15 hrs, moderate use. For me, it's an improvement over the stock battery. FWIW, once I popped in the rezound battery, I wiped battery stats in CMW....

My rezound battery was doing great until the first weekend when I had to switch it with the stock thunderbolt one on the fly. Since then they seem to perform, at best, the same - but usually it seems like the rezound one lasts even shorter than the original.

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?

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

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.
I am getting the phone for christmas and was just wondering if I have my parents charge it the night before, will it last me all day? What is battery life like on the first charge?
You'll likely burn through it pretty fast on a first charge. Best I know, it's not optimal until about 3-4 cycles.
Mine was pretty horrendous at first and then again for the following couple of cycles after that. Now on 4.0.2 and a number of cycles in and I think the battery life is stellar when you consider the screen size. Pretty similar to my GSII so cannot complain.
My advice. .. take the charger.
Regards.
I got about an hour of continuous tinkering after a 10 minute charge. Had to plug it in after that.
The first charge will be the longest lasting charge you will ever have on this battery - depending on your usage.
LiIons degrade a wee tiny little bit with every subsequent charge.
Thanks, I can't wait to get it.

While this is true, I dont think its calibrated the first time.
I got my nexus yesterday and charged it up from 50 to full and it was literally at 0% 10 hours later, today is a different story, I've been able to get about 12 hours of use out of it and have about 35% battery left

Calibration only affects the battery icon, if they use poor logic to calculate the charge. The system can read battery voltage precise to 0.001 volts and it's actually quite easy to gauge a LiIon cell: 4.200 V = full, 3.600 V = empty (without load on the battery)
My first charge only lasted about 5 hours, and that was because I was playing with the thing the whole damn time. ;-)
My first charge
This is what I got on my first full charge. Was on Wifi for most of the time. Bluetooth was on often in the beginning to transfer files.
Used GPS for like. Facebook sync was off. Gmail, Google+ on. No Reader, Google Photos, Docs sync.
I bought the extended battery and it both were about 40% charged. You'll want to burn it down completely till it powers off, then give it a full cycle.
You'll kill it just by setting it up, playing some games, playing with the OS, reading XDA Rooting guides, taking pictures etc.
Just kill it, then put it on the charger while you get a shower and dressed.
...then you'll probably kill it again by the end of the day cause you can't stop plating with it.

I got a Naztech 3000 mAh "extended" battery, since my stock one lasts for around 14 hours on a single charge. I figured I may add an extra 6 hours or so, or use my phone a bit more during the day.
So, here's what happened.
Day one: 4 hours after I charged my "extended" battery, I was down to 15% charge. 1 hour later, it was at 1%. I hadn't used my phone AT ALL. Charged after 6 hours of (no) use.
Day 2: Pretty much the same.
Day 3: Ran Battery Repair and wiped battery stats. No change.
Day 4: Used my phone heavily, and noticed it stayed at 1% for a couple of hours.
Day 5: Noticed a pattern. The battery will drop to 1% within 3~4 hours of use, and will stay there for around 9 hours. Then it'll turn off.
So, the "extended" battery lasts for some 12 hours - tops. 3 hours after charging you won't know how much juice you have left, since it stays at 1% from that point on.
Bottom line: don't waste your money, the battery is crap.
I have the same issue but not with that battery, i've been trying to find a way to fix it, none of the battery voodoo has worked for me yet
after my phone shuts off because it thinks it's dead and i plug it in to charge, within 2 minutes i have about 20% or more charge in the battery, then after 15 minutes it's about 50% or more charge.
is that same thing happening to you ??

Sort of, yes. It charges in half an hour, tops - if the phone is turned off. If I then turn it on, the phone shows 40% charge, or so - and tops 10 or 15 minutes later. Bizarre!
Happens to me also but only with the replacement battery i have.? It discharges fast and stays at 5% for a few hours. The OEM Battery 1880mah works fine about 1 and half day

I am having the same issue with my OEM Battery.Is there any solution for this or can we set the indicator to show the charge according voltage of battery bcoz i have noticed that charge time is good only indicator is not showing it accurately .My phone last full charge lasted more than 17hrs but it was on 5% in 2 to 3hrs of use.
Update: Today my charge was at 100% at 10.00 AM. With light usage, the phone died at around 5.30 PM.
My battery seems to report better percentages of juice left if I use Kholk's kernel, but I'm not sure exactly why. It doesn't go along very well with Faux's kernel, though.
...can't say much about the factory kernel. Haven't used it much myself.

Actually, the atrix doesn't support aftermarket batteries. Motorola says so, and Mugen says so. That battery is fine, you can use it on 1% for a while. And when it dies charging from 1-99% is accurate for my battery. But when you hit 100% all bets are off.

Did you turn phone off to charge, and pull battery and after it boots to a ?. You should let it sit there for a while and try again.
Mugen has an extended battery for the Atrix:

Of course, that one is $119, so it probably will work as intended...
Yesterday I got 6 hours out of my charge. I got fed up and swapped the battery for the stock one. $25 I'll never see again...
Is there a preferred battery charging regimen for the One X battery?
That is, is it better to, say, always let it drop to 15% and then recharge to 100%, or can/should I charge whenever possible, or in smaller increments?
Also, are there disadvantages to using the phone while charging (as I tend to do quite a lot )?
Thanks!
i normally let mine down to about 10% then just charge it too 100%

Right, but do you know if this is actually the way to go with the Li-Po battery or are you, like me, just winging it?
When i first got my phone i let it run down till it asked for the charger, then left it on charge over night.
I did this for the first 3 or 4 times as i found this yields the longest battery life, since then i charge every 2 days regardless what percentage is left always over night though.
Going to leave it tonight & see if it will go till tomorrow night, its been off charge since 7am on Friday morning so far & is still on 46% a total of 39 hours so far.

You get two days on a charge? Are you a wizard? Although, having just got the phone (and possessing the patience of a 5 year old), I've done a lot of start-stop charging, which I suspect isn't optimal.
I'll try to refrain from trickle charging for a while, see how much difference it makes. Thanks.
Another battery charging thread? Just plug in the damn phone! It will take care of the rest.

I have noticed that the battery does drain in strange amounts.
I have my wifi & gps on constantly, my phone went for 2 days 5 hours & i received a text at which point the phone was at 34% battery.
The phone was put back in stand by & the phone went totally flat in the next 4 hours, this i find strange as over night in stand by it only uses 1 - 2%.
There is obviously a bug in the way the phone reports its battery state, by my reasoning this must be some 10 - 15% lower than what it is reporting.
It does seem to have some difficulties reading the battery level correctly. I've noted a couple of times that it shows a significantly higher charge level (+5-7%) after a reboot. Which is hardly likely to recharge the battery. (Unless I got me one of those perpetuum mobile, in which case, yay!)
Has anyone else noticed that 100% battery lasts much longer than any other percentage?
For example, last night I had my phone charging while I was watching TV and fell asleep. When I woke up a took my fully charged phone and went to bed while leaving it off the charger. I woke up five and a half hours later with the battery still at 100%. I then used it for 15 minutes of browsing before it finally dropped to 99%. However, if I had went to bed with less than 100% it would have drained probably 1-2% in the same amount of time with no usage at all. It almost seems like 100% is really only like 98% and it can actually be charged to more than 100%. After it drops to 99% the drain rate is pretty consistent.
I actually noticed this when I first got the phone almost a month ago and at first I thought there was a problem with the phone being stuck at 100% because it stayed there much longer than any other percent.
Anyone else see this? It doesn't really bother me since everything below 100% is very consistent. I'm just curious.
Same happens here. I listen to music (bluetooth to truck stereo) for about an hour everyday on the way to work. When I get there it still says 100% every day. Then after about an hour in my pocket doing nothing it magically says 96%. I have been suspecting that the on screen percentage is not registering the drop in power for a short while. But maybe I'm wrong.
I remember the Nexus 6p used to do that, haven't experienced it yet with my pixel though.

I have noticed that as well. Usually, my ~30 minute bus ride consists of my phone draining between 5% to 10%. But when I have the phone start from 100%, it's never drained beyond 5% by the end of it. Must have something to do with the fact that the phone charges slower when it reaches 80% or above (which they only claim to prolong battery health, not battery life). Eh, won't complain about it :fingers-crossed:
