Slight oddity with my Vibrant.
Occasionally when I charge the phone, it will show that it is completely charged--battery gauge will show full, About Phone will show 100% charge, all of that good stuff. When I unplug the phone, my battery gauge will instantly drop to 97%.
Additionally, for the entire duration of this particular charge, my battery life will be total crap. And by total crap I mean draining 1% in five minutes with the screen off, going from 97% to 78% in two hours with the only use being a quick check of bus schedules.
However, if I notice this 100-to-97 instant drop and plug the phone back in until it charges to 100% again, it will not display any of this odd behavior and battery life is awesome as usual, with standby power consumption at 1-2% an hour.
So... what gives?

Dont worry about when you unplug it, its just a inaccurate reading.
It happened to me this morning with Axura, and my battery showed 97%, but the 3% was given back without me knowing, does your phone stay at the 97 for a longer time? it should, and also some people say do a battery calibration.
its like
charge till' 100
drain it to 0
charge till 100
and then on clockwork recovery go to advanced and do wipe battery stats or something
^ im not sure someone correct me if i'm wrong about the calibration.
I conditioned this battery after flashing the ROM last month. You have the directions mixed up... should charge to full, boot in clockworkmod, delete battery stats, reboot, drain to 0, charge back to full.
And no, it doesn't stay on 97 for longer than it should; as I stated in the OP, if it does the 100-97 drop, the battery life is significantly worse than when it acts normally.
I get the same thing. Actually at the moment I am trying to unplug... see the 97% and plug it back in, it will then say fully charged, I unplug it and it says 98%. I am going to repeat this until it actually says fully charged when I unplug it and then reboot to recovery and wipe the stats.
What I am confused about when it comes to reconditioning and wiping is even when the phone says "fully charged" when I reboot to recovery and wipe, once the phone has rebooted it says it's charging again. Should I leave it in until it says fully charged or unplug it after it boots?
It seems to do the 100-97 thing primarily when charging via USB. Almost every time I've seen this happen was when it was charging off my laptop.
I've noticed also that when it does this, the battery icon (I use Segmented Battery Mod) shows "100" solid without a flashing plug icon. If I unplug it, it will drop to 97. If I plug it back in and it actually charges completely, it will flash between the plug icon and "FULL."
hmm...mine does it no matter how I charge it.

Mine USED to do thar with Nero beta 3 now on Axura IRS dine I've been using it for 20 minutes and still at 100%

Updated to Nero v3 and now I have the problem constantly. It will always claim 100% charge when it isn't actually fully charged.

If you've flashed the ROM, do the "recondition" -- or if you have a stand-alone (external) charger, just charge it full, then put in the new battery and wipe your stats. (The recondition thing -- charging, draining, then charging -- is just a theory that on the second full charge you'll get "more" charge in there after a full drain -- I doubt this is true, especially if your battery stats are hosed to begin with.)
As for the dip after you unplug it -- this is just the battery manager varying the maximum charge level to optimize battery life. Laptops do this all the time -- even when they're plugged in, they'll let the machine run on battery power here and there. For a new battery it might only let it dip to 97%. On one of my laptops it has decided dipping way down to 86% is optimal. Just depends on the battery health, usage patterns, etc.
Battery life was pretty bad when I first flashed Nero, but now that I've wiped battery stats, the battery life seems much better. It still does the 100-97/98 thing, so I'm guessing it means my battery is still pretty good despite all the heavy use!
The JL5 modem seems to have worse battery life than JK6 (only very slightly though) but it doesn't get stuck on EDGE like JK6 did... net gain in my opinion.
No matter how long my g tablet is plugged in,
it does not charged until the battery meter says 100%.
It always get charged upto 96%.
Is there anyway to fix this problem?
Is it something that can be fixed by clearing batterystat.bin?
If that so, can I do that using adb? Thank you.
khunny,
This is pretty common with the G-Tablets.
You can run it down all the way and then go into CWM and tell it to reset the battery stats.
But often as not that doesn't change much.
My personal advice (I have one that often does the same) is just ignore it. If it's 96%
you've got no problem and at less than 10% you better be thinking "charge."
Rev
Mine only charges up to 96% as well. Gonna try to reset it in CWM after it drains. Hopefully it works, cuz while having it only go to 96% isn't a huge deal its something I would like t be able to fix.
search is your friend
It is normal. Gtab treats 8.3V as 96%. In theory, 2cell li-ion battery 100% of charge is 8.4V. But, such battery does not like to be overcharged (it will shortened battery life).
mine did charge to 100 percent before installing vegan 5.1 supplement? Now it charges to 98 no matter how long i leave it plugged in? There has to be some way to alter the battyer stats to show 100 percent if it is??
Mine finally got to 100%
I had this tablet only for a week or so. I have installed Vegan 5.1.1. I noticed the battery only charged to 95% or 96%. I have drain the battery all the way, and then "Reset Battery Status" in CWM. But, it did not work the 1st time. Then, I drained it again. After the tablet shuts off automatically, I would push the power button to turn it on a few times to drain it more. Then, I reset the battery status in CWM, AND, I "Fixed File Permissions" right after the battery status reset. Then, reboot the device, and it reached 100%
Note: I drained the battery at work, tried to turned it back on about 3 times after it shuts itself off. After I got home, a few hours later, I turned it back on one more time, and the battery showed 2% and stayed on for quite a while. Not sure why that is. Hope this helps.
Hi all,
I have a question about battery life on the Simply Honey 2.7.2 ROM
My phone is usually idle overnight, but i notice a drop of about 25-30% in 8 hours. Is this usual?
Here are some screenshots
Battery Plot (1.26 am to 9.26am) Battery was 100% at 1.26
System details
Top Apps
Is this pretty normal for overnight battery drain? The Device usage indicates almost no use..so i'm wondering why the battery is draining.
Any help would be appreciated.
Thank you
I'm having the same issue. With Darky's 9.5 the phone easily last a day, now it's lasting 9 hours or so. I just flashed the new ROM yesterday.
This is from the Simply Honey post:
HOW TO RECALIBRATE YOUR BATTERY (by heartagramm):
COMPLETE GUIDE!!!
You'll have to use the phone for about 1-4 days (although it varies depending on the phone and battery used; every phone is an individual). It runs out of battery. Yes. Let it run. Recharge. After 3-4 recharges the battery will "gain" it's performance back.
After 3-4 full charge/full drain -cycles, do the following:
1. Charge the battery up to fullest.
2. Keep it plugged in to charger, and reboot to recovery.
3. On the recovery, go advanced, wipe battery stats, scroll on to yes BUT Don't wipe them yet. When you're ready, quickly remove the battery cable and push to wipe the battery stats.
4. Reboot the phone, use normally. Let it run completely out of battery.
5. Charge the phone back to full. Turn off phone. Charge until it says 100% on the green bar and vibrates for full charge.
6. The Important Part. Remove the charge cable for 0-0.5 seconds and plug it back in instantly. Let it charge to 100% again. Do this 1-2 times again, so you've done this 2-3 times total.
7. Reboot to recovery, wipe the battery stats again as on the step 3.
8. After wiping the battery stats, plug the charger back in the phone.
9. Reboot to ROM. Keep the cable plugged in. Keep it plugged in for about 30 mins to 2 hrs. Unplug. Should say 100%, mine did for about 40 mins after it depleted onto 99%.
And this is the way you should really gain great battery performance.

Let us know if it sorts itself out after a couple of days...

Thanks. I will try this.
I recently downloaded a Battery Calibration App from the market too (NeMa) and calibrated my battery using that..but I'll try this method also.

I switched to Doc's ROM and battery life is back to normal. I'll try Simply again after a few versions.
Sent from my GT-I9000 using XDA App
I don't think there are going to be new versions, because he's now doing some Gingerbread based ROMS.
Which one is Doc's ROM?
I'm on SimplyHoneyV1.0XE and have been for a couple of days. This is my first Simply Honey experience but I think this is the best battery life I've ever gotten on ANY ROM including stock. Given it is a little early in my test to determine just how good it is going to be but I would recommend you give it a try and see how it does on your battery.
P.S. My findings were based on the fact that after a 100% charge, light usage (2-4 phones calls, and several texts) for almost 10 hours I still had 89% of my battery. Pretty impressive if you ask me.

I'm pretty sure they perform the same function. When you touch the "Calibrate Battery" button, the app automatically performs all the steps mentioned (wipe battery stats, mainly).
One app you might try is Juice Defender. I've used it a few times, and it worked well when battery life was an issue for me (I've switched to Axura, and it isn't anymore. Neither with Bionix).
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.

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!

If I keep my phone on charging even after its on 100%, it starts rolling back. As in from 100 to 99 then 98, even if its pluggen in.
Don't know what kind of a problem this is, hardware or software.
Or there's some issue with the battery.

Maybe You have some program that syncs something all the time. Did You try to turn off data and wifi. You can always check it if the reason is the hardware or Software. Just make a backup of Your whole ROM, delete the data and leave the phone over night. I hope it is only software problem.
EDIT: Does Your battery go hot while charging? Oh, and try to wipe battery stats

After wipe while still in xrec pull batt then unplug. Now plug in phone then insert batt. Phone should boot in charge mode( big batt icon only on screen) dont start phone untill light green for 1-2 hours to get full charge .

As mentioned above as well, this is normal. After charging to 100%, the phone stops battery charging, and will activate charging again only when battery falls a bit (say 97%). Also, battery heating while on charging (and also when using the phone continuously while playing a game) is normal. Relax.. your phone is fine
@ToledoJab
I am having the same issue with battery... phone switching off at 15%, even at 22-23%, when playing a game or something. But switching it back on, and leaving it idle, phone might run for another 2 hours. So it is the extra load while running a game that the phone cant take any longer (i remember getting the 15%,10% and 5% reminders earlier while playing games)...? Does the battery calibrate method actually help in your case? does it go all the way down to 0% or 1% before shutting down.. ?
I just did this after posting that. And yes my phone reported warnings @ 25% 15 10 5 and then shutdown @ 1%.
This way is like reconditioning an old rechargeable ni-cad batt.
All this does is completey drain batt then, with least amount of drainage (phone on, apps& radios running) allows battery to full charge.
There is also a way called recalibrate battery. But this way over charges the batt.
EDIT: I think the phone load will effect reported batt left. I think batt gage use average loads to estimate remaining power. Meaning games, full brightness of LCD, radios -3g -GPS -WiFi -Bluetooth will use more than avg power
edit 2: I found this thread also has some very good points and links. after reading this i will not intentionally take my batt to 0%. I hit 0% about 1-2 times a month on accident as it is. i will just make sure when i do go 0% to wipe stats (dont know if it helps or not) then preform a long (overnight) full charge with phone off.
