[Q] CM9-tenderloin charging issue - TouchPad General

Hi everyone,
I'm not sure this is my case only or it applies to everyone
My touchpad won't come back to charge under CM9 if the tablet is dead.
I have come across some posts which saying you will need to boot into WobOS and get it partly charged and reboot it back to CM9.
Has it been fixed or there is a workaround
Thank you

I experienced this for the first time last week. I had toboot into webos like you said. I did quite a bit of searching for a fix but couldn't find anything.
Hopefully someone else can chime in with a link.
Rezound, rooted, loving it.

If your battery is completely dead, It takes a LONG time to charge it enough to boot. Just leave it alone overnight on the charger and try again.

hi what i have experienced was if the battery is dead, it will take about 15 to 20 minutes to charge until it come up again. however the battery level will remain at 0 percent no matter how long you charge it for

I have read people leaving it over night and still havent had enough charge to boot. I dont know, I have never let my battery drain all the way. I just read people have problems when it does.

question about reconditioning battery

yesterday after flashing nero 5 i wanted to recondition, so while sleeping at night i charged my phone to 100, and now during the day time im trying to waste the battery, but during that i got caught up on adb and connected my charger, and left it there, now its back at 83% battery, does this mess up the reconditioning process? or do i have charge back to 100, then do it all over?
anyone? please lol

what you should do is drain it all the way untill you cant turn it on anymore and leave it chargin all night turned off, and when you wake up turn it on and let it charge untill its full again, then boot into recovery and wipe batt statt , and you should be good to go mine last about 20 hours after i did that

I did just about the same with mine, minus the chargin all night turned off, and I am getting about 20-24 hours with mine, which is more than I need as I plug it in every night

me to im near a power source or computer all the time so
What you should do is keep letting it drain until 1% or so. I don't think you need to let it die completely. Charge to 100%. Boot into recovery and clear battery stats with the charger still plugged in. This is the important part. Then drain the battery and charge to full. Then you should be good to go.
question, after draining to about 1%, does the phone have to be off? and can i use the phone just a bit while its charging?

The general consensus is that when you condition you should charge the phone while it's off. I don't know enough about battery chemistry to tell you why. Just do it to be safe
Battery "recondition", actually does not "recondition" the battery, it is a trick just to get more accuarte readings (that's the only reason you reset STATS)
The battery may not charge up to 100% and will never do, just following this procedure. It will just say it is @ 100% when you actually are @ 85 or 87, that's why the sudden "jump" you see.
Best way to try to get better readings is charging the battery till it says 100%, unplug it and plug it again a couple of times until it fully charges and follow the same procedure.
Once yo did this a few times, turn off phone, reboot in CWM (with the phone never unpluged) and clear battery stats. turn off phone and unplug,,,,
You will got at least more accurate readings

Android Police did a piece on plugging and unplugging your phone to get up to 100% (it's called bump charging, see below). They recommended that you NOT do it because it doesn't get you much additional juice and you wear your battery out faster. Normally I just charge my battery up to 100% (no drain), wipe the battery stats, unplug and go until it dies. I use it while it's plugged in and still get a full day easily out of my phone.

I hate to be the bearer of bad news. You can not condition a Lithium-Ion battery. All you are doing is wearing it out prematurely by deep cycling. Every time you do this you destroy your over all battery life a little.
I have posted about this here in several thread, and I am getting a little tired of having to tell people NOT to do this because they don't search for themselves. Do a search on the forums for deep cycle li-ion and see for yourself.
If you want to know the technical reasons why, Google is your friend.
so we just deal with what is perceived as faster battery depletion?
Im asking because As i have posted on another threat I am a complete freak about my battery life.
Basically yes, I have 3 batteries to go around all day, although I us the car charger, if for any reason one day I take the train to the city, I will eat up 2 and a half batteries in a day.......
I had 3 batterys for my hd2 I need to get 2 new batteries for my vibrant. I guess im just tripping because I tried and over clock kernal and it seems like its dying faster while the screen is off

anyways, i've heard it all, and even i used to agree with people like you, and it probably DOES wear out my battery, but the first time i did it, i got 6 hours more in battery, does that mean that my batterys dying because its giving me more life?

Yea, just chill. It is all in your head. From ROM to ROM, usage pattern to usage pattern, and app version to app version - there are just too many variables to worry about. Just use your phone, charge it when it needs it, and relax.
Your phone's battery is going to get less life as it ages. There is nothing you can do about that. Also, it will likely only get 2-3 years before it needs replacement. If it gets less than 2 years it is because you have been "conditioning" it. which ages it prematurely and also causes how long it lasts between charges to shorten as well.
Li-ion does not have a memory, so conditioning is an inherently false concept. Recalibrating the devices ability to read the battery is a different story, but it should only be done if it really needs it (like it thinks it is at 1% when it is at 20%), and it should never be done more frequently than a minimum of 30 charge cycles or if you charge it once a day when you go to bed no more than once a month. Less frequent is better.
So sorry, you need to find something else to obsess about. Might I suggest getting Team Whiskey to make BlackFroyo the default theme, use the 5 bar signal meter, the larger numbers on the battery, and the hacked camera the used the power button to take pictures. That would save all of us some time.

Nice link - try reading the stuff by the engineers that work with batteries for a living now instead. You do know eHow is just a site where any idiot that thinks they know something can post, right? Are you going to reference wikipedia next?
BTW when you recalibrated your battery and got 6 more hours, did you do anything else that might have explained it? You know like flash a new effing ROM? That might possible change a few things to do with your power usage.

it was a joke
and no, i flashed Nero 4.1, and then used it for a week thinking the phone would adjust to the battery and new rom, it didn't.
then i thought i'd just take a chance and recondition my battery, it was my first time, and it worked out great.
and trust me i'm a heavy user.
roughly 300-400 texts per day.
20-40 phone calls
music about 5 hours per day
and i play soem games, but thats understandable because playing dungeon defenders uses like 30% battery per hour bcz of the high graphics and such.
a bunch of app downloading.

[Q] Concering batterystats and major battery level problems.

Alright, before you tell me to remove batterystats.bin and move along read this carefully.
I've had my HTC Legend for about 8(?) months now. Around the same time, my mum also bought one. I rooted mine, flashed CM 7.0.0, up to the newest nightly now. She left it as she got it, only upgraded to Froyo when the update came out. Everything is working great, except for the battery statistics.
Around 4 months ago my mother first complained about her battery not charging to 100%. It got worse over the weeks, and the battery level also started dropping faster and faster. It has gotten to the point where, when she gets it off the charger in the morning, it's around 52% (Even though it's been charging for forever, and should theoretically easily be on 100%). After about 5(!) minutes of using the phone, it will have dropped to a 2% battery. Battery life, however, is hardly suffering. She can just walk around with a 2% battery for the rest of the day. Obviously the batterystats are totally ****ed up. After 2-3 months my phone started doing the same, except it does it less severe. I can only charge to 50~60% as well too.
Around this point, I started looking around, and found about how android saves it's battery levels. I rooted and flashed my phone, and using fake flash, I booted into Clockwork recovery, mounted /System (S-on phone, can't edit system when phone is on, still no s-off for hboot 1.01..) and removed the batterystats.bin. I did in a couple of ways now, including the build-in option and using Android Commander. My phone, however, still won't charge past certain numbers.
Now my questions to everyone here is: Did anyone else have problems like these? Any solutions you'd like to suggest? Are batterystats/total voltage also saved somewhere else?
I'd like to point out that the battery itself is not damaged or anything. When my mum's phone had these problems, and mine didn't yet, we tested her battery in my phone, and it would charge to 100% just fine, and the levels weren't messed up.
Her problems started around the time she flashed Froyo from the official update. I can see how flashing a new rom messes up the batterystats.bin, but apparently that's not the only file being wrong?
Any suggestions are VERY welcome.
Tl;dr: Phone battery won't charge past 50% or so, battery level drops to 1% in 5 minutes.
EDIT 1: My mum send her Legend to HTC to get it ''fixed'' THREE weeks ago. She got it back today, them saying it was fixed. After a good 10 hours in the charger it still won't go to 100%, and after 30 minutes the battery levels dropped from 70% to 1%. I think it's quite shocking how HTC can say something is fixed without even trying to charge it to 100%.
you can try this, can't hurt
Turn your phone on and charge it for 8 hours or more
Unplug the charger
Turn your phone off and charge it for one hour
Unplug the charger
Turn on the phone and wait 2 minutes
Turn your phone off and charge it for one hour
Unplug, turn it on and use as normal.

Thanks for the reply,
sad to say I've already followed steps like these atleast three times. Including charging without entering pin, when off, when on, etc etc. Still, thanks for the suggestion.
no such problem yet ... but i'd be interested to know if you were able to resolve it... it cant be a coincidence both you and your mom 's battery levels acting up.

Could be so, but I don't think we're the only people in the whole world to have this problem. I'll keep this thread updated with any information I might stumble across and any other solutions tried. If anyone could tell me where the maximum values for the battery are stored in android it'd be great, seeing how deleting the batterstats.bin file didn't help, there must be another file in android tracking battery..
Hi,
so you're not alone. My Legend is showing the exact same symptoms.
I bought my Legend used via ebay and the seller told that the battery won't fully charge. No problem i thought, just buy a new battery.
Even with the new battery it won't charge more than 60% and it decreases to 10% in 5 minutes.
Just had a test. Even with 60% power at the beginning and 10% after 5 minutes it still was working for 80 hours!
unfortunately i don't know when the probs started to occur. My legend is also with the official Froyo flashed.
regards
Mario

Everyone seems to have this problem since Froyo. HTC fixes it by replacing the motherboard, which basically means they replace 90% of the phone... So basically, there is no real fix around. :/
seem like hardware fault..

Could be so, but it seems strange as the problem starts occuring after flashing to froyo. [Even though going back to eclair doesn't seem to fix it..]

Lumia 800 battery fix maybe?

Hi this is my first ever post so please bear with me, my lumia like many others suffers from ridiculous battery drain I have the new software and yes I can now charge to the max. However the battery cannot last the day out until I discovered this. Most people I know continually top up there battery, but if you just let it completely die then do a full charge overnight you may like me notice a massive increase in battery life, I have changed nothing about the way I use my phone the only difference is it now lasts 2 days easily.
The figures quoted in battery saver have not changed but as the day goes on the time since last charge goes up but so does the estimated battery life.
My phone is now IMO fantastic.
Maybe if you tried this it might work for you too, do hope so.
One word of caution when the phone has died the phone cannot be switched on until charger has been plugged in for some time, in my case about 20 minutes after plug in the phone switches itself on.
Please try and maybe you will also have the most amazing phone too.

I think I experienced something similar. I then flashed the new firmware and am back to lower battery life. Need to take the time for a few discharge cycles.
The problem with this approach is that some Lumia 800's cannot turn on after a full discharge. People have gone to great lengths to be able to get a tiny bit of charge so that it could power on. Some people have had to send them back for repair.
Question to TS. Do you let it completely die every time now or can you charge it whenever and still get the great battery life?
battery fix maybe
Hi after letting the phone die I have not done it again since, I just top up as needed or at night just as you would normally do.
Hope this helps.
Okey. When you say "completely let it die" do you mean letting it drain and turn off. Or do you start it once again after the first turning off and let it die again?
battery fix maybey
Just use the phone till it turns itself off, then plug in charger, this is when you may have to wait for the phone to switch on, mine turns itself on after about 20 minutes, charge as normal then use as normal, charging as you would normally do.
Good luck.
I did this once intentionally about two weeks ago. Did not notice any difference really. I do not have "bad" battery life to begin with. Not great either though. But it easily lasts a full day with heavy usage which is all I need really.
12 hours since last charge. 73% left on battery. I have used it "normally". About 10 quick calls. A few messages. Browsing on the marketplace installing a few apps editing contacts etc...
I'm pretty heavy on my usage, too. Lots of Mix Radio, sometimes played via bluetooth.

Transformer Prime Main Battery not charging past 56%

I have searched the forums and have not managed to find a solution to this problem. This started a few weeks ago with the tablet only charging to around 80% charge but over time it has slowly reduced to only around 50-60% (today 56%). I have 2 chargers which both have the same result. Both charge the keyboard to 100% and both charge the tablet up until the point the icon changes from charging to a normal battery indicator at only partial charge. I have tried resetting multiple ways and times and a full factory reset, to no avail. Any feedback / insight into the issue welcome.

You might be right. I was hoping there was some kind of misreporting issue. Something similar happened a few months ago but one day it just worked to full charge and was fine for a while. The intermittent nature had me wondering if there was a software issue.
Have you cycled it completely?

I didn't fully discharge the battery to zero and recharge if that is what you mean. I try to avoid it since a previous phone fully discharged and was a nightmare to get going again (sealed battery). I called the people I bought it from and they organised a RMA at a local store, so it is out of my hands for a while. Hopefully it comes back without any dings etc. and a working battery. Thanks for your input.
I know with android sometimes the fuel guage can go crazy, if it were, say, an S2 i'd say go to recovery, reset the battery stats and cycle the battery. If you FEEL the tablet is only lasting half the time it should then the battery may have issues. If it doesnt seem like your losing any play time just the guage is weird then ya i'd suggest playing with it till it shuts off and let it fully charge, sometimes android needs that just to calibrate the battery stats.
You never want to let these batteries discharge to complete 0 however most have a undercurrent protection where they shut down if theres too little power so damage doesnt occur. (My S2 actually stopped charging once when it got well below 0, i thought that was cool)
Anyways, good luck with the RMA, let us know how that goes!

It was definitely only lasting half the time it did when it was taking a full charge, so I think it is likely a battery issue. These things happen. Now it is just fingers crossed for the RMA.
Just got my RMA back and they have replaced the entire unit, which will hopefully do the job. Currently charging (totally flat on arrival) so patiently waiting to have a play. Forgot how much I like the form factor.

Droid Bionic charges to full then when unplugged dies

My Droid bionic is having problems with battery. It has been problematic for a long time but recently it has gotten worse. At first it was just saying it had 5% battery after a few minuets when fully charged, then a few years later it went to saying 5% battery directly after it was unplugged and then a few weeks later it was dying every 5 minuets unless unplugged. The battery is a new battery and the charging cord and charger work and it gets a full charge but it keeps doing this. Does anyone have any idea why and know how to solve this problem? Also i want to count how many people are having problems like this I will get back to you via email if you have this problem with the solution if and when i get it.

u sure charger is compatible??
change it if not
Try wiping batterystatus.bin from data/system after a full charge.
Most likely the battery needs to be replaced. In my view, charger is not a problem.
