Charging from 95% to 100% takes 2 hours

Well lets say my battery is 35% when i get home, it takes about 45 mins to get to 95% then from there takes about 2 hours to get to 100%. Running CM7 on the Telus DHD.
I dont know if this happened with stock as i rooted as soon as i opened it

Try downloading CurrentWidget and then charge your phone until there are zero milliamperes showing on the widget. Then wipe your battery stats and reboot. This should calibrate the readings to be a bit more sensible/accurate, for both usage and charging.

As the battery is charging and nearing full capacity the current slows down thus making the charging process slower.

This does make sense. Guess im just too used to the iphone

It's not iOS, Android or WP7 - all Li-Ion batteries have to be charged that way. Just one of these OSes preffers not to give accurate information to its users about baterry charge, signal strenght etc. What you don't know can't hurt you seems to be Apple's moto. Still 2 hours for 95% to 100% is too much.

About 2.5 hours is what I'd expect it to take to charge from 35%

k well today i got home and the batt was 35% (heavy usage) and it only took about 45 mins to get to 90%. From there it goes much slower.

Going to CM7 I had the same problem with my battery being at 95%. I'm planning to drain completely, wipe battery stats immediately, then doing a full charge.

mine only takes just under 2hrs charging from empty to 100%.

It depends if you're charging it through your computer or the wall. If i charge mine through the computer it takes about 3 hours if the battery is completely empty. If i charge it through the wall, it uses about half the time, but the battery empties much faster. Some phones has so called "speed charging". That means that you can choose between good battery life but long chargr, or short charge time but bad battery life. It depends on how you charge it.
But, two hours from 95% is not normal.

This might be a clue to the cause of the problem. I'm now running stock ROM and being in the process of deciding if I should go for Revolution HD or stay on stock, I read numerous posts of battery stats problems. I think the OP should try to wipe the battery stats and see if that would help.

3500mAh Extended Battery From Amazon Question

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?

Ahh... yes. I know now which one

I have the exact same battery and I'm wondering is the percent shown total BS? Mine is showing 87% with 4000mV left after charging overnight with an SBC kernal.

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.

FYI, after 12hrs, i'm only at 70%. That is with very poor signal at work all day, and playing pandora on the way in.

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

How do you override that value? I looked all through the widget settings and I'm not seeing it.

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.

Ebay extended battery charging question

Just this past week I got two of these extended batteries off of Ebay. Although I'm still calibrating the one seen on the charger. I really haven't found anything concrete on how long a battery like this is suppose to charge for? I've read things such as charge it in the phone (which the phone will charge it as if it's the stock battery) use the charger that came with it (charger in the photo continually thinks that the battery is at full charge, when it was in the phone until it died.) To battery calibration apps which I'm reading don't do anything, to bloatware. So if anyone can help me out, it would be great. And sorry if I made any mistakes in this, sending this from my phone is kinda hard for me.

I have the same extended battery and I can say that I have no idea. I'm using custom roms, and a charge lasts anywhere from a day to 3. I would say charge it in the phone til full, then drain it by using it, and do that a couple of times, it gets better as time goes on.

I have the same battery and when I use the phone to charge it it takes 6 - 7 hours and it lasts pretty good but since I've installed the shot of awesomeness by team inferno the original battery is good enough for my day... My max was 1d 14 hrs 10m 20s with 2% left... Big thanks to team inferno!!!

Rezound battery doing worse than stock

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.

Battery issue.

Hello everyone.
Past couple of weeks I have been having issues with my phone battery. No matter how much battery I have left when ever I play some game or edit photos my phone will all of sudden drop from 70%(or any given point) to 0% and switch off. At first I thought my battery was not calibrated so I drain to 0 and charge to 100 while it is off for couple of times but problem still occurs. Also when this happen my phone charge only upto 80% and stop charging until I unplug and plug back in order for it to charge100%.
Is there a way to fix it and how could I check if my battery is bad?

First, battery calibration is basically a placebo. It does nothing nowadays.
The whole thing about waiting a few days after installing a new rom or firmware so that the battery can "settle down" is real though, but is only because the new firmware will be doing a lot of background stuff and thus drain the battery more than usual.
Second, the only way to tell if your battery is bad is to try a new one. Unfortunately.
Based on your symptoms though, your battery is DEFINITELY bad. I'd recommend either sending the battery out for warranty, or buying a new one. Or both- you'll end up with 2 new batteries that you can swap out if you're a heavy user.
FYI Warning- apps that claim to scan and repair your battery are scams. There is no way to scan your battery. It isn't a harddrive.
Just thought I should warn you before you get desperate.

Been having similar issues with mine as well. My phone will show about 20% or more left in it, but then the phone ships down as if it was completely drained. When I plug it in, it will show the battery is dead. Also, like a little whole ago, it showed 25% left, but when I plugged it in, it went to 12%. It also continued to drop even while plugged in and showing it was charging. I did a battery pull, cleared the cache, then rebooted. It showed 18%, but only 23 minutes left to full charge. I did another battery pull, and it now shows 1 hour and 43 minutes left to full charge.
Like you, this has been going on for a few weeks now off & on.

I had problems a little while back (not as bad as these). Mine would die with the percent showing around 5-8% remaining. I took the battery out, held the power button for about 30 seconds, then continued normal use. I read somewhere that doing this somehow helps. I don't know if it's true or not, but now my phone doesn't die until it hits 0%, so something did change.
