Battery indicator wrong? Dead battery? - Desire General

Hello people!
I have some strange problems with my battery, at least, i think my battery is not doing the right things.
The problems:
1) battery is on charger. When reached 90% the LED is on green. For me pretty strange, since you expect a green LED on 100%, right?
2) When my battery is on about 15% my phone already shuts down. Why already on 15%, i mean for me 5-10% is more obvious.
My question to you:
Is my battery dead?
Is my battery giving wrong indications or something?
Thanks in advance!

That the light turns green at 90% is normal in all AOSP rom's. That your phone shuts off at 15% is probably because you "calibrated" your battery once. In the calibration thread they mention a fix somewhere.

Yes i have calibrated the battery before indeed. Can't find this fix so far. Anyone else who can find this fix. Theghost1233 thanks for your reply ;-)

Battery indicator inaccurate boost, anyone else with this problem?

My battery indicator (in status bar) likes to increase each time I restart my device. Does anyone else have this issue?
I am charging and the indication shows as charging plus the percentage is increasing like normal. However, when I restart the device it shows more than charge percent. For instance, show 56 % but after restart device shows 82 or more than 92. Thank a lot in advance for taking your time to reply
I've tried searching to see if it's a common problem, but I haven't been able to find others with the same issue with Artemis
My Rom: Touch_4.02_Vanilla
I've the same issue, and I guess its normal.
hmmmm...well..for past one year...i have my 100% battery accuracy.
Have you noticed when charging its getting charge slowly and draining is also extremely fast after restart because its showing more than whats charged.. Maybe i guess its my battery got screwed up

dude..
your battery has lost its charge..
you need to Buy a new battery..
i had the same problem..
*buy new battery
*charge untill green led shows
leave device off while charging, dont switch it on untill its charged.. or it wont charge full..
...
its a common battery problem with the artemis/p3300
leave device off while your charging though
Thanks dude for the reply.....relieved to know that its not my device nor rom....else I would be spending time trying to flash roms and roms.....till i buy another battery Ill stick to ur tip ' Device Off While Charging"

Quick Battery Drop in Initial 10%

Hi all,
I am puzzled by my problem. I am using Virtuous 2.7 + King's BFS kernel #4.
My phone battery will drop quickly from 100% to 92% right after unplugged from the power cord. By quickly, I meant I did not use the phone, killed all tasks, and battery will drop to 92% literally in minutes.
Bump charging, wiping battery stats, wiping dalvik cache, killing all tasks are not helping at all. I don't have SetCPU, but someone in the forum mentioned they have SetCPU, and it is not helping either.
Is anyone having this problem? Does anyone have any idea on how to solve this?
Please help.
Thank you!!!

I spoke to RMK as well as others about this in IRC, doesn't look like anything we can do, deep in the HTC code I guess.
I have the same issue using SkyRaider 3.1. Battery is 100% then after 5-10 minutes drops down to low 90s. It bothered me at first but after several days of moderate to heavy use and still having almost 50% battery left at the end of the day, I just figured it was some kind of bug when reading the battery level at the beginning. How is your battery life overall? If it's like mine, then i wouldn't worry too much about it as long as it's lasting longer. I'm using the 1750mAh battery from Sedio.
I was having the exact same problems until I went back to stock everything and bump charged. Took the OTA for 2.2, rooted, custom recovery, bump charged, wiped stats and cache and now I'm good to go. I usually dont think crap like this works but it made a huge difference in battery life and stopped the 100-90% problems I was having.

I found this on EVO forum, but I don't know how his solution works. I personally don't think this would be the solution.
http://ip208-100-42-21.static.xda-developers.com/showthread.php?t=704272
I am using the 1500 mAh battery.
My battery life is uptime around 24 hours and awake time around 6-9 hours depending on usage.
so you're not having the issue anymore, after going back to stock (non rooted) with the official OTA 2.2?

Do you think format the phone and wipe all the data will help?
Have anyone tried formating the phone?
I've searched and found that the cause is the phone saying the battery is charged fully when its not basically so to fix this after it goes to 100% while the phone is one then u should turn it off and let it charge fully from there

I did bump charge this phone, but it still drops like crazy.
I'll try this out tonight.
Thanks!
Is this a once time fix thing or do you have to do it every time you charge?
bump charging 4 or 5 times in a row (basically bump as many times as you need to to get it to where the light turns green withing a minute of 2 or plugging it in again) and then wiping battery stats solved this for me... kinda.. i still have to bump twice, but after that it'll stay at 100 for a good while and work it's way down normally, no jumping 10% down..

That is bump charging. Something htc is unable or unwilling to fix.
The issue has been known for a while and you have to 'bump charge' every time to avoid the 5-10% drop.
Here's their response about fixing the "bump charge".
"Dear **********,

Do you bump charge every single time you charge right now? It's pain in the butt if I have to bump charge everyday.
Yup every day. 4 or 5 times is way overkill though. Just charge phone until green, turn off (don't need to unplug), wait until it turns green then do the plug/unplug one more time.

Went to stock (official OTA), rooted, custom recovery, bump charged, reset stats and cache and I'm good now.
I charged it to "full" while it was powered on. Once the light turned green I turned the phone off, charged again until the light turned green. Took about 25 minutes. Powered up in recovery wiped battery and cache and now I'm good. The key is after doing all this you have to let the phone completely die.
If you're wiping your battery stats after a bump charge, you will have this problem every time you don't bump charge.
If you wipe your battery stats after it goes green without a bump charge, you won't have this problem.
This is because the software thinks the bump charged battery levels equal 100% charge. A bump charge adds approximately 10 percent of charge.
Formatting your phone or any software changes won't actually do anything other than wipe your battery stats while your phone is not at bump charge levels.

The reason this happens is because the battery gets charged fully to 100%, and then is allowed to slowly drain back to 90% (or so) before it's charged back to 100% again. This is how Lithium batteries are charged.
Try this: charge the battery to 100%, and immediately disconnect it after it's full. Notice how the battery doesn't drop to the low 90's immediately.
The reason "bump charging" appears to work is because there is no drain on the battery, since the phone is off. It goes to 100% and stops.
There's nothing we can do code-wise to fix this; it's just how the battery technology works. Keeping it fully charged at 100% while on would damage the charging capacity of our phones.
Btw.. wrong forum.
Solutions in search of a problem
Let me preface this by saying that I’m not an electrical engineer, or any sort of expert on phone hardware, but I think a couple issues are being confused. I’ve seen many posts about this battery “problem” here and elsewhere and an important point is being missed. People are confusing what the battery is actually doing with what the phone SAYS the battery is doing. They are NOT the same thing. The battery is a physical device and it will do what it’s going to do.
Battery life is a function of battery quality, initial state of charge, and demand. If you want the battery to last longer, look at ways of reducing demand. What applications are in use? How long is the screen on? What brightness level? Overclocking and undervolting settings? All these will affect ACTUAL battery life.
At lot of the “solutions” discussed have nothing to do with conserving energy use, but have everything to do with messing with how the phone REPORTS the state of charge. A good example is the issue of the initial drop reported by many users during the first few minutes after unplugging the charger. I see this on my own phone. If the phone is “taught” that 100% charge is when it is totally crammed with juice and plugged in as well, it’s not surprising that there is a good bit of voltage drop (+/- 10%?) right after unplugging. Does this mean there is a problem? NO! It’s just the battery doing what batteries do. A lot of the suggestions about wiping battery stats and such have nothing to do with saving energy. They are ways of fiddling with how the phone REPORTS its condition under various circumstances.
My advice: if you are happy with how your battery lasts, over the course of a day or so, then learn to relax, crack open a cold brew, and revel in just what a great phone the Incredible is. If your battery isn’t lasting as long as you need it to, then look at ways to save power or get a larger capacity battery. Tweaking the battery meter function is simply a feel-good exercise and won’t get you any actual improved performance. END OF RANT.
I can confirm that my gf's phone and my good buddies phone(both were never rooted) have never had a problem with the phone charging up slow first off(both phones charge about 1% per minute). And since they accepted the OTA, have not had the problem of charging to 100% and quickly jumping down to 90%. For instance, the other day my buddy charged his phone while on to 100%, played a game for about 2 minutes and closed it, battery was at 99%. Now I have tried and continually try every possible solution to my battery dying quick and charging slow, but am realizing that this must just be the cost of customizing my phone to my liking. And at least for the moment, a stock 2.2 DINC is just not an option for me.

Sorry that I posted in the wrong forum. I thought this is related to the kernel or ROM I am using (Which is development right????).
Not to question your knowledge about the "battery technology", but why is it only happening to certain people? Nowadays most device are using Li-ion battery, why this phenomenon do not occur to all devices?

Battery calibration - never finish charging in recovery?

Hey there,
I tried to calibrate my battery the last few days...
There where so different descriptions on how to do it right.
But well at some point they all said to charge the phone turned of ( well it automaticaly jumps into recovery, right?).
And it was said charge it till the led goes green.
But I think it never happens in my case.
In one case I fully chagred my phone powered on and then turned it off, plugged it in again. The red/orange led staied there even after 3 hours...
The other day I fully discharged the phone and wanted to charge it in recovery mode. So I plugged it in, the red/orange led began to flash, recovery booted and I went to bed. About 10 hours late I woke and the led was still flashing as before.
I had no patience and turned it on. With the system running it tells me, that its at 100%.
Turning it off again unplug and replug it will show the red/orange led again but not flashing.
Its a european desire z (germany)
On Virtuous 0.9
With clockwork 2.something
Any ideas? Should I have been even more patient to see the green light in recovery? How long could it take?
Thanks,

It seems the question of how to charge the battery pops up at least once a week now, with the same misconceptions. There is no such thing as calibrating the battery. All you are doing is calibrating the battery meter (just a volt meter) on the phone. Li ion batteries cannot (and should not) be calibrated or conditioned. The best way to calibrate the meter is to charge the phone to 100%, drain to about 20%, repeat a couple times. You should not discharge the battery below 20%. I cover it a little more in depth on the following post:
http://forum.xda-developers.com/showpost.php?p=11026655&postcount=7
I don't see any advantage to charging the phone while its off (except that it will charge faster, of course). I always charge mine while its on (with screen off).
I don't know why your green light is not coming on. Mine comes on after the phone has been charging for about 2 hours or less. But I am on the stock ROM, so its possibly something to do with the ROM, so you might have some better response by searching or asking in the Virtuous thread.
Yeah I know that you just calibrate the voltage meter but its just easier to say battery calibration.
Well maye the misconceptions occur because there are plenty of different answers spread and its easy to become confused. I just avereged over these methods and the consensus was to change fully while turned off.
The only way I could think of loading in recovery is better, is that the software prevents loading when it thinks battery is full (but in fact it is not), but I relly dont know.
And you say even after deleting battery stats there is no need for discharging till shutdown (to show the limits or anything)? To reset on full battery is enought?

I want to calibrate battery and delete old stats.
Thanks & Greets
Well, your problem first if that you said you had recovery 2.x and that if you turned it off it automatically jumps to recovery.. you seem to have the first recovery that the power off feature wasnt quite working well.. upgrade to a 3.x then like the above user said but drain the battery until it reaches %15.. thats when the Connect To A Charger popup shows up.. and charge to 100% and do couple cycles of these..

[Q] Phone Charging Question

Problem:
I have been reading as many posts as possible but I haven't come across my exact situation. I apologize if this is posted elsewhere.
I am running a rooted Dinc using CyanogenMod 7.0.3. If I charge the phone while it's powered on, the amber led turns green as soon as the battery indicator hits 100%. However, recently I've noticed that if the battery is close to being full, say 90%, and i power it off to charge it, it actually takes longer for the amber led to turn green. It might take 20-30 minutes longer.
I've also noticed the amber light turn green when the indicator only showed 92%. In trying something different I also noticed that if I charge the phone while it's powered on, then turn the phone off, the led goes amber and takes another 20 minutes to turn green again (I might be accidentally bump charging in this example but I'm not sure).
Attempted Solution:
I've read that a battery recalibration might help. I tried one method that requires the battery to be pulled after a full charge, but my phone won't boot while plugged into the wall if there's no battery. Then I tried booting into recovery, where I found an option to reset the battery stats... which I just did about 5 minutes ago.
I'm going to see how things go tomorrow, but is this normal? Has anyone else experienced these things? Thanks.

The kernel and the hardware charge it in different ways. That's why there are differences. DInc is famous for ending charging before the battery reads full. There's already a thread on that. there's not much point in getting hung up on how that thing charges. Be glad yours isn't like mine; a battery that discharges faster than it charges. Seriously.

Before I had a fast charge kernel (thanks Chad!) Using GPS with the stock VZW car charger, my battery would go down while it was on the charger!

On AOSP roms, the LED will turn green at 90% and charge slower from 90%-100%. Perfectly normal, and I think on any rom it will charge slowly from 90%-100% to protect the battery.
The battery will charge further when you turn the phone off, what you described is what's known as bump charging. If you do this, you should notice a slower drop from 100%-90% than usual, because the battery is charged to a "true" 100%. When the phone is on and charging (above 90%), it simply keeps the battery above 90% even if it says it's fully charged, and this is why the inc is notorious for the quick 100%-90% drop.
If you do a bump charge and then clear the battery stats and use the battery calibration app will you need to bump charge again or will it know what the true 100% capacity is and keep the droid lasting longer. Not noticing much of a diffrence when i went from 1300 battery to a 1500. May get a bigger batter that'll fit the stock battery door cause I'm trying to get the best battery life i can get.
Thanks guys, I appreciate the help. I think something else that has thrown me off is that before I rooted the phone I wasn't able to see the actual battery percentage in numbers... all I could see was the battery icon. Things are now making more sense.
After recalibrating my battery I bump charged the other day and I was able to get almost 2 days out of my phone on light usage. Without bumping, I was able to end my day yesterday at 50% under my normal usage. Which is a noticeable improvement. Normally I end the day with about 10-20%. The big test will be once I go back to work next week. The cell reception is real spotty in my classroom, which I know makes the cell radio work harder.
Thanks again.

Battery drains fast when charger plugged in - Urgent help!

I have a odd problem. I have the Leedroid custom rom with its kernel installed, and it seems as when i plug in the charger that the battery DRAINS extra fast instead of CHARGE. I have no idea whats going on. The red LED light is on as usual but when i turn my phone off for a while and let it charge and then turn it on i only had like 5% battery left when i started charging at 20%. What do i do? Is this some kind of bug?
I dont believe that i cannot charge my phone, but im afraid that if i leave the charger in my phone will become completely drained of battery and that i then wont have any option left.
Please help me, my phone only have 5% battery left, and if there is something i can do before the battery drains completely, tell me as fast as you can!
Thanks!

Never mind, i got it to work. It seems as if the battery didnt get enough electricity. Probably because i got the charger hooked up to a powerstrip whom also have a halogene spotlight connected to. That was on. The phone died and when i tried to charge it the red light flashed. So i turned off my spotligt and tried bashing the powerbutton.
The LED started to statically glow red and the phone turned on. I almost panicked because i rooted the phone yesterday and have only had the phone for like 1 and a half week.:angel:
