i ask this because my battery stats have gone dumb dumb on me. first i had a 40% instant drop when rebooting and since 62% charge on my phone Battery Life how been showing 4150mV. it may fructuate 50mV (i think it keeps topping battery off and then when it goes down a tad i tops off again ).
So my question is then is my battery already fully charged and my battery % is off and if so why would it keep slowly going up when the mV's are no longer going up?
fyi i trust this battery widget. used it in 3 phones for 2 1/2 years. hasent update recently either

When your battery is fully charged it is generally around 4200mV. It seems like your battery is not calibrated. I recommend the battery calibration app. Search it in the market. Very easy to calibrate. Just charge till its at 100% and close to 4200mV and then hit calibrate.
Also, to monitor your battery stats (voltage, %, mW usage) I recommend the battery monitor widget. It shows graphs of your mV as well as your battery percentage over time.
Thanks bro, I apreciate the indepth answer. I thought it was 4200 but I gotta be sure u know

I recently had a problem with the battery of my Defy, shows that this charged and stops charging even at 95%. I tried calibrating the battery, with the app and the same from the recovery, and removing the battery.
I can't think what else to do. Help Please!!
Edit, i'm on CM7.1
Have you tried wiping battery stats from recovery??

have been facing the same problem right since the day i upgraded to CM7..but what i have observed is that even though it says that the battery is fully charged @ 95%, it still keeps on charging...check after half and hour and it goes upto 100%..yes, but when u start using the handset after charging, this 5% comes down very fast!
Im having the same problem with the first 10% of the battery disappeared really quickly? Im on standard rom 2.2.2.

Just my observation... In Defy though the hardware is capable of 1% reporting of battery state the software is configured to assume near values. For Example 25% to 34% is considered 30% and 35% to 44% is considered as 40%. Hence when the battery reaches 95% it assumed 100% and reported as fully charged. But if you don't unplug the phone the charging will continue to 100%. In my Defy I don't see any significant difference in drain other than the first 1%. To know the exact charge I use ledefy with LED indication. Ledefy can be configured to change the colour of LED at exact 100%.
yeah, but now it goes up to 100%, i think its solved, but if this persist i'll report the issue to cyanogenmod forums...
thanks for the info pprakash
One thing I found that showed an accurate battery % is Android Circle Battery Widget.
This showed my battery % to 1% accuracy (1% 2% 3% rather than 90, 80, 70, 60 etc)

LEDEFY also have similar notification. It can display the same in the notificatin bar saving space on the screen or if you are having customer rom you can use a different framework-res.apk which can display 1% values ( This is my case for exact values ).
Try clean the battery stat created by older ROM, and use Battery Calibration free app which you can find easily on the market to calibrate ur battery... i think that would help
Hi, sry for my english=(
When i charge my battery its normally charge to 80% and then becomes 100%.
Try calibrate battery but this doesnt help. Also try another roms and kernels.
Is it a battery issue?
U can buy new battery from DEALEXTREME.com
so its the only way?
Try this.
Charge battery to full. Leave plugged in, Turn off fastboot in power settings and shut phone off. Light will turn orange again and let it charge til green. Boot into recovery and wipe battery stats. After this let the battery drain as low as 10% before recharging to full without unplugging. Do this a few times over a few days. If you don't get more accurate percentages after this then the battery could be messed up.

thx i will try.
i have the exact same issue. i have done battery stat wipe..flashed multiple roms over and over with full wipe and all that. battery charges up to 80% then the LED turns green..and stays that way till it reaches 100%. it jumps from 80% to 100% in just a few minutes.
battery jump
I wouldn't worry Lendlord mine does the same (see attached pic) you can see the green line jumps up from 80 to 100 but doesn't jump down from 100 to 80 under use. The picture is taken from Battery monitor widget, it's a great app which shows mv, ma, % and temp and even keeps a text log of what ma drain there has been allowing you to monitor battery drain while you're using your phone or while it is sleeping.
Here's a great guide aswell of how to ensure best battery life by memnoc:

so thats mean that some battaries have the same issue=( And there is no solution for it...
HTC failed again...
first GPS and now the battery. Bad, very bad!
And one more request.
Can someone post your current widget log?

I have the same thing happen to mine, i think its because you've let your DHD die due to low battery levels and that damages the battery which i think causes this problem
..letting the phone shut off because of a completely discharged battery is NOT good for the lifetime of Li-ION batteries.
The battery could be hurt and the amount of mAh the battery is able to store might be lower after.
Also trying to 'pump' the battery to fully charge by connecting / disconnecting while the phone is down is not a good advice because li-ion batteries also don't like overcharging.
To be sure that the battery is fully charged due to its ability it is sufficient to let the phone be conectet to charger or usb overnight.
Android uses the voltage of the battery to estimate (!) the % charge value.
Android supposes the battery is fully charged when it enters the voltage of about 4.2 Volt which is the charging cut-off voltage for li-ion cells.
Now when charging again the conceded voltage is reached more quickly than estimated by android, so the system is 'surprised' of this rapid charge and changes the % value to 100% because the conceded voltage is reached more quicklyy as supposed.
(Try to fill a 0.5ltr beer bottle into a 0.33 glass)
This is the normal of aging for li-ion batteries.
Consider for yourself if it's acceptable for you or if you should by a new battery.
by the way... be careful with cheap china batteries for 10$.
Offers with exaggerated values (up to 1600mAh) will mostly keep their promises
only for the first two or three charges only and will than fall back to 800 mAh or even less !

Pudel
Yeah...
My battery started to do the same thing for a week or two. It will charge to 86% then it jumps to 100%, saying it's charged.
This is normal afaik, nothing to worry about.

actually，it's the problem of your rom , in the framwork.apk . unzip it you will get a lot of battery icon form 1%to 100% in the res file ，if it made mistake，that 'your problem. you can go to uot kitchen to coustom it again.
Nope!
I've solved my problem. I've bought a new (original) htc battery, and the new one works great. I haven't reflashed the rom, or made any new modification. Just added the new battery.
So, yes, it's a faulty battery.

Download Current widget from market and charge ur phone then wait for the 0 ma then download the battery calibration app from market too and calibrate and unplug ur phone, u can aslo reboot to recovery and wipe battery stats hope it helped you
I bought a new battery today, a Chinese knock-off battery which claims to have a capacity over 2000. I live in Mongolia, so that's basically my only option if I want a replacement battery, since there's basically no postal system here.
When I first put in the battery, it showed a 59% charge. After a few minutes and maybe a reboot, it showed a 20% charge. It consistently drained down to zero, and I'm charging it now.
I've experienced really strange battery drain with the former battery (also a Chinese knock-off) where it loses maybe 10 percent an hour on idle, so I figured the battery needs to be replaced. Is there anything I can do to calibrate it? I have a feeling that the charge is actually more than is being shown, but no way to confirm my suspicions. Am I right just to try to charge it to 100% and discharge it to 0% until the battery life gets better, or is there something else to do? I should mention I've tried resetting the battery stats in CWM with no real effect.
Thanks from Mongolia.
Go into recovery when battery is at 100% and go to advanced then clear battery stats or download battery config for rooted devices and clear battery stats that way.

Clearing battery stats achieves nothing other than deleting the stats on the what has been using battery power. Battery calibration isn't required on our phones.

if you want to increase battery life for your new battery, charge it fully to 100% whenever you charge it will increase charge storing capacity of the battery

Never, ever I repeat never let your battery drop below around 5%, and always charge it before it reaches zero. I use the Guage Battery widget v3 pro as it is very accurate, but you can also get the free version. You can & should use the free battery calibration tool from the Google play store, simply install it & charge the battery to 100% then run the calibration App. simples

Over the course of months of flashing, I have noticed that my battery life drains really fast. I'm currently running AOKP. I think I calibrated the battery correctly yet I still have terrible battery life. I charged it to 100%, used an app, Battery Calibration, to reset the battery stats, let it drain to 0%, the plugged it back in. The battery said 57% so I charged it back to 100% yet the battery life is still awful. My brightness is at the lowest setting, my WiFi is off, and I am using Greenify to hibernate applications. I've attached pictures of my battery life (from GSam) and pictures of what my software looks like. What is causing the drain? How can I fix it? If anybody can help, I'd be very thankful.
Edit: I have a Hyperion 4200 mAh battery. I replaced the stock battery but it didn't seem to make a difference. The voltage reads at about ~4200 mAh when at 98%.
Edit 2: My battery was at ~60% then I shut it off and plugged it in. It is now at 2%... Should I charge to 100% then reset battery stats?
In the last few days I've been seeing some strange issues with the battery graph. It has been saying that I've been off the charger for over 30 days and the battery level line is off the chart on the right. It seems to only be resolved when I charge to over 90% which causes the battery graph to reset.
Anyone else have this issue?
Mine does the same because I only charge to 80% all the time to help with battery longevity. The app I use to limit the charge also has a button to wipe battery stats. It's called battery charge limit

Even if you only charge to 80% it still shouldn't have the graph line totally off the chart. This only started recently. Before I never had an issue even if I didn't charge over 80%.
New experience just now.
