battery/charging problem.

i'm using donut's android build and this battery/charging problem is driving me nuts. my battery lasts 4-5 hours max and the weird thing is it only takes 10 -15 mins to show my battery is fully charged. i tried flashing again, left the phone until it dies by itself and charge it, left it being charged over night but none of them helps. anyone having same issue? i know with android on our vogue the battery life sux but is it this bad??

might be time for a new battery. It should take 30 to 45 mins to charge. And it should last longer than that. How much time do you spend playing games ect. Gps also is a battery drainer. Also alot of data usage.

My battery can last all or most of the day with moderate use on Android.
If you are running off an SD card, try booting back into windows for a day or so to see if you have a similar battery problem there too. Actually, windows battery life was MUCH worse for me. The difference is that Android does not wake the screen for Calendar alerts or text messages like WinMo does... though in Android you do still get the vibrate or sound alert.

win mo is actually quite ROM dependent (NFSFAN's ROMs got awesome battery life). android is pretty kernel dependent. if you are charging overnight, and using latest zimage/kernel, and turing off syncing (background data), and that is the battery life you are getting, you need a new battery.

i use gps a lot as i work as a field technician but i don't have gps turned on all the time while im driving as the screen shuts off by itself in a minute or so. maybe gps is still working even with the screen shut off? and it's a nand install so trying with winmo is not possible. i had much better battery life with winmo for sure. if i turn off the syncing will i still be able to use gps?

Which NBH are you using? The newest ones are way better than the older ones. If your using a current one check out tatnai's FAQ... http://forum.xda-developers.com/showpost.php?p=5599516&postcount=33

It's the kernel. you know the file you rename RUU_signed and you flash.

I am definitely having this problem as well, and the charge does not last very long it seems either. Was much, MUCH better in the Windows Mobile builds I was using previously.
I am on Bell using the basic HTC Touch

Same problem here. Brand new battery on bell.

Yeah, although battery life is positively improved and pretty decent now, there is definitely still something funky going on with charging. I still don't rely on / believe when the phone says it is fully charged. It happens too quickly to be possibly true.

I have the exact same issue and it is absolutely a problem with charging within Android. I have two identical batteries. One was fully charged in winmo before I flashed - I took it out and swapped for the other one. Flashed it with that battery in and charged it overnight. It only lasted about a half-day. Came home and swapped out for my other fully-charged (in winmo) battery, and it lasted for more than a day. Same settings, same use. After it discharged, I recharged overnight from Android and it behaved the same as the first - discharging in about a half-day.
What gives?
I'm curious what builds people are using? I'm totally new to this but I'm using warm donut with voguimg-240x320-06-04-10.nbh. It seems that nbh isn't posted on the sourceforge site yet - maybe I should switch back to an older one?

Maybe kernel problem.
I'm experiencing the same problem as everyone.
Lately my battery suddenly drops from 100% to 4%.
When I put to charge, it reaches 100% very fast. Should reach only 5%
I think it can be a problem in the kernel.
Now, i'm trying to solve it. If I find something I'll share with you
I can not determine which kernel brought the problem...
23/04 - 16:16 (GMT-3 - Rio de Janeiro) - Trying an old kernel
23/04 - 17:00 - Nothing. But came to the conclusion that the problem is with the battery.
Battery really "thinks" its 100% charged, since it accepts flash a nbh without the need of the phone is charging. And this only happens when the battery is at least 50% charged...

My battery life is pretty bad and I recently bought a new OEM battery. Coming of NSFANs 6.5 rom, Myn's warm donut on 240x320 is wonderful but the battery life is pretty lousy.

Power off at battery 15%

I noticed, a few others, but should be minority has the same problem as mine.
My N1 powers off itself when my battery shows around 15% or so.. sometimes 17% sometimes 14%, never lower than 10%.
I already tried to wipe battery data at recovery or deleting the battstat.bin file etc etc but it is still like that.
Is there a solution for this and any reason for this?
Majority of people's phone only power downs below 5%.
Many thanks

Use the battery calibrator, it's in the development section.

Try bump-charging* then clearing the battery stats
*Charge phone to 100%, unplug it, turn it off, charge again till indicator goes green

actually this i have tried a few times already but it never helped.

My phone turns off at around 19% now after I played with the battery calibrator app. (I set the life at 100%, was lazy to run the full cycle calibration)
Its powerful and probably can fix your problem.

He said he was too lazy to complete the learn cycle, which is part of the calibration technique. There is no sense in trying to pick "pieces" of the process and hope they work, they won't. Start with step 1 and follow the directions to the letter, don't skip anything. I would suggest reading the instructions a couple of times prior to starting and ask questions in the thread if you aren't sure. There are several of us that monitor the thread and will respond quickly...myself during US daylight hours and Temasek in the evening (he's in asia, I think).

Thanks. Wish there was a quicker/easier way.
I'm currently testing a direct way using simple math:
If 1452mAh is 100% how much is 19% ?
i.e. 1452/100*19 = 275mAh (for me)
I've set "full40" to 1452-275= 1177 (the calibrator app's minimum is 1200 so I just set it to that.)

That may work as a guess-timate, but the stock battery comes rated at 1452mAh and stock age is set to 94%, so you would really be setting to 1128mAh unless you reset age to 100%. It really doesn't take that long to set up the application for learn mode...just a few minutes. It does take 31/2-4 hrs to fully charge the phone and complete learn mode if you set the min. charge current to <20mA. To speed things up, just set it to <40mA as you won't miss the little bit of extra juice.

hmmm good point, i never thought of that lower limit. we'll see if we can update the app.
but to answer this thread's question, the age register in your phone is now out of whack, and you need to set it accordinly to allow the battery to go down to 0%. the learn cycle determine's the proper "age" value and sets it accordingly.
you could also guess an age value, say 83%, would be close. but really there's no reason to not do the learn cycle and figure it out.
BTW all these values are stored in your battery's chip, and it needs to be updated to new value.

Quick question:
1) Sometimes even after I turned on the "Detect Learn Mode" my Current occassionally dropped below -200mA (e.g. 160mA) for a quick while... will it affect the result?
2) "Turn off" means turning off the Detect Learn Mode right?
3) where can I see the "Charging current"? Capa.?
Thanks

What if I rotate among three different batteries on a regular basis? I have an external battery charger too. Will the calibration be in any way useful or will it get confused by the changes?
I have my original January 2010 battery, a December 2011 replacement from HTC, and a MOMAX battery that also holds up a pretty good charge.

you can rotate batteries no problem. when you do a learn cycle, the age value gets written to the chip inside the individual battery. so you can swap batteries no problem. just make sure that the correct age value shows up when you swap, cause sometimes the age resets when removed from the phone. just set it manually back to your proper age if so.
we were trying to add "profiles" support to the app so you could swap batterys and it remembers the parameters for each and sets them accordingly when you swap the battery. but i dont know how long that will take...

Okay good to know. I bought this charger:
http://www.amazon.com/PowerGen-Mult...CAT6/ref=sr_1_3?ie=UTF8&qid=1295658169&sr=8-3
And it's pretty neat because I can just position the pins myself to charge any battery I want. I've tried it with camera batteries, Huawei U1250, Moto Milestone and RAZR, and Nexus One batteries. It works really well and it's somewhat future-proof because it will probably work with my next phone's batteries too =)

[SOLVED] Incorrect Battery Values

This seems to be quite a common and somewhat obscure at the same time.
Many people have reported installing a new rom or even just powering up their phone and seeing a battery % much different from what they expect. Most often much lower than it should be. Evidently this corrects itself after some time but it's a real problem if your display reads <15% because you really have to plug it in then, even with you know you have 90% battery!
So, here's the solution after testing it under different circumstances over a few days:
Simply boot your phone when it is not plugged in to a power source and battery % will be accurate.​
That simple. Silly LG!
So, if you flash a new rom, unplug the USB cable before you reboot...
Hit 'Thanks' below for the 50 reboots I did to prove this...

hehehe jups allready figured that out on myself tho haha. But indeed that's kinda silly of LG

What about every time I use a custom rom the battery % indicator jumps right down to 90-95% when unplugging from charger ? Do you have a solution for that ?

Sorry to say the same..
Even while charging with the phone shut down, pulling it off the charger and then booting this happens. On my phone I have experienced it on all MCR's.
It's really not a big deal as long as the battery performs as Stock 10b, that build has been stable batterywise on my phone. But staying stock isn't too much fun

Well, every time I charge, whether I reboot/shut down before unplugging or not, my charge always maxes out at 96%.
Annoying and I'd like it sorted if at all possible.
Anyone?..........lol

ye i got that exact same issue i was wondering why that was happening and hoped that a simple reboot would fix it but its a bit more complicated than that i suppose...
also the battery reset in cwm didnt fix the loading till 97% w/e percentage.
when i install the stock rom it allows me to load it till 100% though pretty weird stuff -.-

I had a replacement netbook battery that could only max to 90%. So, over the weekend, I practically drained it to 0% (not a healthy practice for Li-ion batteries but I was desperate). Took out the battery for a while, and then recharged for several hours. Well, it seems to get up to 100% now.
Perhaps you could try using the the phone until it very low on battery before recharging. Maybe the charging process in the phone needs some sort of recalibration. But should not be doing this all the time as it will reduce Li-ion battery longevity.

Let mine totally die last night so it wouldn't even turn on at all. Took out and replaced battery and then charged it overnight and hey-presto, when I unplugged it this morning, it stayed at 100%.
Solved indeed....for me anyway. Feel free to try the same and post your results.

I'll be sure to try your tip man. But not easy drain it completely when I always need the phone :=)

I guys! I've got the same problem.
I think that it could depend on the "full battery popup FIX" that Paul introduced in his roms by the FR8.
So I would like to ask Paul if you can create a patch to remove that fix. Just to try it!
According to me, incorrect battery amount depend on a wrong voltage read error (offset introduced?) by the rom. :blink:
In my case, I have followed many times battery wype procedure without positive issue. The matter leaves only by flashing original roms.
I think that if Paul have written a wrong battery values range (to delete the battery full popup) that can be traduced in an incorrect battery status displays.

It was occurring before Paul introduced that change unfortunately...

After I wrote here, I registered a premium account to Paul's from modaco site and toke a custom fr12 rom without "battery full popup remove patch". Now I'm going to sleep and plugin the 2x to charge. Tomorrow I'll write here if is that the solution...

Perhaps, but you can not conclude it was introduced by MCR. You logic is wrong there.

Even without "battery full popup fix" it doesn't work good...
Battery level, when unpluged, stay at 100% for 2 minutes afterwards drop down fast until 85% then drain normally...

I'm getting huge battery display problems no matter what I do.
When I took it off the charger this morning, it said I had 100%... thats fair enough. However it stayed at 100% all day, so to "refresh" it this evening I restarted the phone, and low and behold it now says I have 27% left. But again, it's just sticking at that value, even with me now plugging the phone into the wall to charge. It simply says "Charging (27%)" and won't budge, likely until I restart the phone again.
Sometimes it works fine, it seemed to be doing ok last night before I put it on the charger. Any tips/suggestions? Is this something likely to be fixed when the Gingerbread update rolls around?
This is my first real smartphone, and am fairly annoyed as its giving me a fair few problems that I've not had from other electronic devices.

As I stated in another thread, I had the same issue while on MoDaCo Fr12. However, after reverting back to stock, the battery percentage is spot-on and I'm getting up to 48 hours use out of it.
Draw your own conclusions.

That sounds super, but I'm still on stock too. About the only things of note I've done are root and switching to Launcher Pro. Oh, and Clockwork Mod of course. Perhaps a complete reboot is needed, we'll see how it goes.
Saying that - since charging, my phone has been at 90% all evening, until right this moment when it changed to 89%. It's less than I'd expect on this type of phone for 3-4 hours use (or lack thereof, I've barely touched it), but it's a start eh?

Welcome to the world of smartphones my friend. I've had various handsets over the last 4 years from iphone to android and a day and a half out of the battery is about average......at best. ;-)

Just to clarify, what I meant in my previous post was that I was expecting to battery to drop a lot more than it did. The fact that it only went down 1% in several hours of use prompted me to think that the battery value was messed up.
As it is, I've not charged my phone in the 36 hours since, and it tells me I have 73% battery left. Perhaps it is performing extremely well after all? If that's the case then I'm more than happy with it, but being the pessimist I'm still expecting the phone to turn off sometime with the battery reporting incorrect values.

Battery virtually dropping, hardware or software problem?

Hello,
for months it has been happening that when the battery usually reaches 25% (but not always sometimes even 40ish) the battery indicator drops to 19% and it could either remain stuck at that value until the charge actually drops below 19% and continue the usual drop or it will rapidly drop to lower values in big steps like (19->10->4) in minutes to finally actually automatically power off. The strange thing is that it's all fake! When I power the phone again the % will go back to where it should be before this virtual drop happened and continue its usual drop, it always worked until today when for the first time it continued the "game" non-stop until the battery ended the actual charge (for hours)! You have to consider that i was in a place in the mountains where the gsm coverage was very low/non existent so it could be connected. But it got me worried because it couldn't control it!
Apart from a solution I'm asking also what the reason could be. It could seem like a battery problem but why would the phone actually recognize the actual charge after it powers off and I restart it ? Seems like a software problem (battery driver maybe?). But I wouldn't exclude that it could be the battery maybe when the charge gets low the voltage drops dramatically under stress to a point where the phone thinks its almost empty.
I'm using cm7.2 kang 119 with standard kernel.

Have you tried wiping the battery stats..?

So you say it's done that for a while... obviously it's not possible to pinpoint an app. I guess then you have some funky cruft buildup (say, a lot of rom flashes and some settings getting squiffy) or your battery's dying. I know for sure that the rather excellent Battery Widget Reborn can give a health check on the battery as part of the widget (although I dunno if it's GB compatible). The second solution may be to try a clean wipe. It's drastic, yes, but can clean up any lingering problems if you've been updating for a long time without the occasional wipe. If you haven't...then I dunno.

The thing is it doesn't happen at every single charge! That's confusing! Maybe I'll try to update to #135 and install symbiosis kernel and see.

I'm not trying to be rude. It's just that battery stats are reset after every reboot, so wiping them does nothing. It's also easier to be blunt to get a message across.

But I wouldn't exclude that it could be the battery maybe when the charge gets low the voltage drops dramatically under stress to a point where the phone thinks its almost empty.
I'm using cm7.2 kang 119 with standard kernel.

by "sale" you meant "same"?

I have similar problems...
Mine force closes 1 out of 7 charges at a random percentage...today it was at 53%...it shows cc% but in reality the battery is drained out...I am not sure what is the problem...this showed up after I inhaled wiui 2.5.25, other than that I have minor issues with this rom...I really like it...only if I could make the radio work...

Bb=725 ril=0218(10b) the kernel is the latest OC kernel from temasek (any suggestions there, is there a better one for wiui/miui roms?).
I'll do a battery wipe after a full charge and see what happens next...

Please don't post questions in the General section
Moving to Q&A

for example. just keeping it standby. it is like full charged after few days. full charged indicates this.
Ok. Take one call or do anything with it. the battery charge goes logaritmically to zero.
What you think?

The battery shouldn't drain that quickly, something else is wrong; the battery might have dimineshed capacity to hold a charge, or you're experincing the 1 GHz bug (reboot with wifi off).

If you mean that cpus run at 1Ghz continuous these runs 200Mhz both I ssh logged to the fone. I think it is battery problem. I have two of this kinda of these: EB-FM7FLU . 1500mAh (hah!) Might be original. both batteries.
I use in several apps these batts, so I think how Li-Ion(Lions) work. Battery drains of course, but never just like this:
Full charge - do something - logarithmic drain to zero.

I need to call to the Samsung service (with my phone:d) and purchase !Li-Ion! accu for this

Said wrong an previos, never serial, but parallel. Serial switch kills the phone parallel does'nt sorry bad english
I try to flash Omni rom later some day.
Remove charger - go - answer a call. - battery dropdown.
Someone testet direct cable from transformers's secontary to handhelds pinouts?
