[Q] Battery Warning Icon Issue. - HD2 Android Q&A, Help & Troubleshooting and Genera

I just charged my phone on HD2 in Window Mobile, it was like 98% and suddenly I just go to Android, when I'm on Android, I got battery warning "!" on the top of my screen, can anyone tell me why is tha? I just know my phone have plenty of battery in it.

I had the same issue on older Android builds. But on newer builds it works for me.

i just installed android last day and having issue with the battery
i can charge the battery from windows but from android the battery aint charge...

You need to ensure that your build is using the latest zimage.
See my signature for the link to the latest zimage, you should know what to do with it.

if you plug the charger in before you boot into android it will charge the battery. Also as mentoned before make sure you are using the latest zimage from http://cotulla.pp.ru/leo/Android/ with charging enabled.

[HOW-TO] Battery calibration

I've just found that on the desire forum, do you think it will word on ours HD2?
vidler said:
Found this on another forum, I have done this a few times myself (do it whenever i flash a new rom because i always clear battery stats, can't hurt). Have found that it does top it up a fair bit. Before doing this i find my desire will drop to +-93% straight off the charger, however this keeps it 100% longer and i actually get to see the numbers 99-94%
Worth a go in my opinion because it only takes 5 mins of your time and can't hurt the phone... So any minor gain from this process is a win...
Hi *******, I understand your concern regarding battery life on your Nexus One device. The following steps should significantly extend the battery life on your phone. Please connect the phone to the charger with the phone powered on, and allow the phone to charge until the notification LED is green, indicating the device is fully charged. Disconnect the phone from the charger, and power it off. Reconnect the phone to the charger with the phone powered off, and allow the phone to charge until the notification LED is green. Disconnect the phone from the charger and power it on. Once the phone is powered completely on, power it off again and reconnect it to the charger until the notification LED is green. Disconnect the phone, power it on, and use it. You need to use this sequence only once. If the issue of battery life on our phone persists, I recommend you contact our HTC accessory department directly.

my guess will be no on this. As i think that the batteries are different. and it might be something with batteries that are in droid devices perhaps.

I'm trying right now i'll report as soon as I have an answer!
I think it should work as it's wiping battery stats in android
im trying it too as we speak
I'm pretty sure that calibration will not work currently in android properly. Cottulla posted a few days back that the battery driver is still incomplete and currently only supports reading battery state and that the write too part of the driver has not been implemented. When the driver is complete and has full read/write battery function this procedure should work better.

thats' true i didn't know that . it may be impossible to wipe battery stats this way
....
My battery wasnt calibrated properly and wudnt charge over 90%. Someone in this forum told me to switch off and charge until green and then switch it on. Now my battery seems calibrated plus i got 2 days of use on moderate use

but ive seen several posts of people calibrating their battery in winmo and reporting better battery life....idk maybe placebo
i will try this too. i myself had an issue today. i'm using chuckyrom right now. i use it at work so i can turn the "phone" off while at work. so it is in airplane mode. i only used the phone today to check the time and played some uno on a break. my battery stayed on 100% for 5 hours. so i turned the phone off, took the battery out for 1 minute. put the battery back in and turned the hd2 on. it was still on 100%. 4 hours later it was down to 94%. i just didn't think that a true battery reading. most days when i have the "phone" turned on at work i only have 10% battery left by the end of the day... just seemed odd to me. idk.
Well, I don't know if this works 'properly' or not but it's certainly had an impact so it's doing something right.
Prior to the calibration I could only charge to 95% or so. Phone now seems to be charging to 100% all the time which is good. Battery life also seems great, not sure if this is down to the calibration or not as I moved to Darkstone V2 (16/08/10) release the day before so don't have a baseline.
FYI, as I type this I'm on 49% battery remaining after being unplugged for 10hrs. Fairly light usage, couple of calls; some texting but quite a lot of browsing and XDA App on 3G and WiFi.
Amazing progress the devs are making. Have been running various builds of Android for a week or so no and haven't yet had to revert to WiMo.

Edit: Couldn't figure out how to take a screenshot without plugging in (and hence losing the 'time since last unplugged stat') - so here's a ropey photo for the inevitable 'screenshot or it didn't happen' remark Seems I've been unplugged for 13hrs not 10... where does the day go?!
Anyone able to do this with mattc Leo + Froyo w/Sense? The charge indicator LED never changes to green.

Yeah, its hard to remember to take a screenshot before you plug it in (or in my case...reboot the phone)
You may want to try BatterySnap...its a free app in the market which gives you a great battery widget, plus a lot of really useful graphs and information.
I upgraded to Froyostone on the 12th...thats why the information is only going back that far...but as you can see, 18-19 hours a day at moderate usage is what I am getting on a regular basis
Cheers
Hey guys, I'm trying this method but my battery won't charge past 99%. any suggestions?

Power the phone off...then charge till you get a green light (Maybe even for an extra 10 minutes or so)...power the phone back up and plug into your charger. now it should charge up to 100%
I dont know if the battery itself is limiting the charge, or if its just the battery meter that is not displaying correctly...Anyhow, the above method corrects it for me whan this happens on my phone.
Thanks matey . I've only had my HD2 for five days but thanks to the awesome resource that is the xdadevelopers forum, I'm successfully running Android on my phone. :-D
AND This is my first WM device, have had iPhones for the past 2 years lol!

[Help] Battery charge

Hello guys,
I have a big issue and I'm affraid not to damage my device.
Here's what's happening:
When I've first started using Android builds...my phone batt. was charging to 100%.
After testing and playing with different builds..it would only charge up to 97%.
After even more testing...it only charges up to 95%.
I've always done a task29 before installing a new ROM, I've formatted the SD card each time as well.
Do you know what is going on? I'm affraid that when I leave the phone charging, it won't stop doing it (the led is orange and the icon of charging is there) thus damaging the batt or the device.
Thank you very much for taking the time to help.

I guess the answer you're gonna get from others is "Search before asking". I won't do so though. The answer might be you are using old kernel, updating kernel should work. Alternatively, switch to WinMo and charge it to full, and boot Android.
You should not let baterry drain to 15%-20% while using Android also
Let you phone charge to 100% in WM and then boot into android.

Charge to 100% in winmo. Leave it still plugged in, and boot android. That way the 100% caries over to android.
why we not sould let batery drain to 15%-20% while using Android
???

This question is way hard for me lolz. Really, I do not know the answer, just an experience I collected from other posts. I guess draining too deep out of HD2 Android will make the battery reading function work improperly
Thanks guys!
Will check if charging to 100% in WinMo and then booting into Android works and let you know.
I'm using the latest kernel available.
some users have reported that letting the battery drain completely in android corrupts the file system on the sdcard. so best to charge when nearly empty or switch off/boot into WM until you can find a power source.
Something that worked for me!
I had the same issue. Charged till 100% for the first few days. Then it used to top at 97%...95...and finally today at 92%. What I do is I let it charge till the led goes green(In android), and then I switch it off and take the battery out. Leave it for a few minutes. Then put the battery in and boot to android. Voila! 100%!
I guess its something to do with the batterys memory or something. It just needs a resetting from time to time.
I also experience the same. When I boot android with battery fully charged, it shows 100%, but when I charge it while running android, it shows max around 90%, even when fully charged. After reboot it shows 100% again.
I do not think it is the battery, but the linux driver.
Moreover, when I boot android when charger is plugged in, the LED does not lit and android does not report charging. When I unplug and plug in the charger, android shows charging and the LED lit orange/green.

I hope someone figures this mystery out soon, this is driving me crazy. When I first started running Shubcraft 1.4d everything was PERFECT. Battery charged fully with no problems & I got great mileage out of it. Then I installed the 1.5 update & it just stopped charging properly. Now no matter what I do it won't fully charge even though I've reverted back to 1.4d. I've tried charging in WM then booting into android, deleting the batterystats.bin file through terminal, letting it die completely then recharging it, all with no luck. Tonight I think I might try fully charging in WM & doing a clean reinstall of Android.

This does work perfect - it appears calibration of the needs this to happen from time to time... I am pushing for 2 weeks now without taking battery out - so it works fine...
Besides this - battery improvement on my end was gained by installing Auto Killer and uninstalling setCpu and all Task Manager Killers, etc...
Just quick sugg for better battery life... (from 12%/hr stand-by I am now easily geting 5%/hr with light usage)...

Really Weird Charging Issue

Didn't see any relevant threads from a Google search, or a search on here. It's not so much an issue, as it is a potential bug. Sometimes the charge level never goes above 99%. It'll charge from say...70%, to 99%, and never get to 100%. I'm not sure if this is my phone, the battery, or an Android bug. I'm using Hyperdroid with Miri's V19 ROM.

I notice this with my phone too. It takes ages, if ever to get to 100%. When this happens I just boot back into winmo and let it charge there. usually if i'm at 99% in android it only takes about 5 minutes or so for my phone to hit 100% in winmo
as i stated before.
Boot to windows mobile once and charge to 100% make sure you are either hooked up to your charger or connected via active sync (other wise you cant get to your SD card) when the power indicator is Green boot to android.
Now you can drain your batt and charge back to 100%. Quic n dirty fix.
Something that worked for me : power off your phone, remove your battery for 1mn or so, and then it should fully charge in WM and Android.

Yeah thats all fun and games but then you have like 99% when you are back in android and the next time you have to charge you wil have to do it all over again.
If you charge it to 100% in winmo and keep it charging while booting android and you wil start with 100% bat and you wil keep it charging to 100% it may take a tad longer then in winmo but it wil get there every time. I ran my phone for about 3 weeks nonstop and full 100% every time i charged.
Yeah the battery doesn't always seem to charge to 100%
I've been following the IRC Logs and they say to charge in windows mobile sometimes as it could potentially effect your battery if it charges to 90% or 96% etc..

Has worked for me in the past...but changed my build so many times that i'm just living with the bug tbh
Its so funny all those big workarounds.
Wile all you need to do is charge your phone to 100% boot android while keeping it at 100% and u are home free but it seems my words are lost against a storm of nothingness.

I used to have that problem aswell. But after like 2 or 3 unsuccesful charges it started charging all the way to 100% without any problems at all. I also noticed that disabling data connection fixes the problem. For me atleast.

[Q] battery driver issues

i currently own 3 units of s200 and have flashed them with cooked roms. however i have discovered a very disturbing fact about almost all the ccoked roms here - the battery driver is screwed up. i ended up changing 2 of the 3 phones battery because it only charges till 55% and 74% respectively, the 3rd phone charges to 95% and is stuck there
2 of the devices came from a same build september 2009 and the third phone is from jan 2010( i guess because it only says on the service receipt).
am i the only one who is experiencing this or there are more of you who had been infected by this bug?
i finally flashed all three phones with 3.03c official for malaysia/singapore
one more thing i noticed, all the roms effected were using somekind of tsowens taskbar icon as well as using non acer dialer.

Which Custom ROM did you used?
used a couple of kubino's
arto's latest
one of yours. (if i remembered correctly... i have to check my download folder)
additional info, the battery will get stuck on the last maximum charge before flashing... lets just say i have 55% batt and i flashed a custom rom... after flash, the battery will not charge more than that.
(it is safe to say that you must flash the phone in 100% batt... my bad, i flashed as soon as the charge goes over 50%... pardon my obsessive flashing disorder)
i even have left the phones connected to the charger overnight and in the morning it is still displaying the same level of charge (+ over heating = almost dead battery = buying 2 mugen 1500mAh's)... at first i thought it was a minor battery update lag bug, but the phones will die within 5 to 6 hours. sometimes they will be switched off for no apparent reason
i seriously want a 6.5.x rom running on all 3 devices because of the touch friendliness but the fact that it gives me battery errors turns me off.
just hope i can use custom roms like i used to on my previous htc devices.

Well your battery is broken.
I have already flashed with only 30 % of battery and nothing happened. Have also flashed my Phone over 200 Times in the last 6 months, in the last 3 days over 50 times - and the battery is still functioning without any problems.
On my Sencity ROM it holds for 2 days without loading.
thanx for feedback
i think i'll experiment on a few more roms. as far as my devices go, the problem was rom specific where flashing the stock rom eliminated the issue.

In my opinion, it is the issue of your battery, not the driver. If you use the original battery, you will find it works fine! The high capacity battery maybe need the special charger. Maybe just because the phone can not recongnize the battery's capacity.
By the way, I found that the battery does not work well with the new style roms. The battery always exhausts faster than the old style rom. For instance, the rom 23140 exhausts battery faster than rom 21057. My battery can stand by for neary 4 days with rom 21057, more than 3 days with rom 21895 or 219xx. But it can only stand by for about 2days with rom 23140 or 28xxx.
well the drivers are just ****ty
i searched thru the forums to find out what is missing... and i find then post that says new roms = new base drivers = recalibrate battery
guess what, i recalibrated my battery even the "broken" ones. now all are working perfectly.
the catch
1. recalibrate all batteries
2. delete any battery icons / taskbar enhancement (can be reinstalled after all this)
3. use any regedit find string "state" without the quotes. find "battery", and change all values to 0
4. charge batteries without turning on device, wait till light is green.
5. turn on device, make sure battery % is showing 100%
6. take off batteries, wait 10 seconds, reinsert battery
7. push vol+ and vol- and press power button (hard reset device)
8. voila... perfect charging battery
tested for 1 day already. the broken battery were not broken after all, its the battery driver. it will not make changes or detect changes from the battery because its from a different base driver (even if the drivers were said to come from official 3.03c bla bla bla.
sorry mates.. its not my batteries. if just one device its understandable. its from 3 seperate devices (one is actually my girlfriend's) so i made a conclusion that even roms cooked from same base will actually have a flaw that can kill your devices......... slowly
bottom note - only flash your phone at 100% batt and reflash stock rom in between flashes.
@ sinocreate
BTW the mugens were bought to replace 2 ORIGINAL batteries that had been damaged by the roms. do read the post carefully.
i think you are competent enough to understand my simple english.

In your step1:recalibrate all batteries. I just want to know how to recalibrate the battery?
I remember that the system can recalibrate the battery automatically from maybe WM6.1 or newer core...
recalibrate
set backlight to maximum
turn off powersaving
let the device run until it dies by itself
take out battery for 10 seconds
put it back in
turn on device
if device turns on - let it alone until it dies again
if the battery have fully discharge, hold the power button red led will blink
once you know battery is fully empty, you can
a. charge using the original acer desktop charger
b. charge using a phone with stock rom
c. charge using your phone (make sure phone is off until fully charge)
wait till green light. then you're done.
the premise of this.
1. every battery has a chip that tells the phone and power management system that either it is empty or charged (voltage level, temperature etc)
2. Flashing custom roms abrupts this transaction of info from battery to power management causing innacurate reading.
3. new base driver will detect different battery level, some are ok and some are not, unfortunately in my case it has a serious error.
4. recalibrating is just a remedy to make sure that both phone and battery starts reporting on power drain from 100 - 0
one more thing, if you think your phone is affected, charge at a minimum of 8 hours (sometime the green light will come out earlier due to the fact that it is not accurately reporting the battery charge)

sorry mates.. its not my batteries. if just one device its understandable. its from 3 seperate devices (one is actually my girlfriend's) so i made a conclusion that even roms cooked from same base will actually have a flaw that can kill your devices......... slowly
bottom note - only flash your phone at 100% batt and reflash stock rom in between flashes.

Where did you find that? Because that is for the HTC Devices. The ROM's for the HTC's use different battery drivers.
For our Acer device there are drivers 2.002 and 3.003. None of the kitchen Chefs use the old battery drivers or replace something in the OEM package.
So, if I say to you that my ROM has 3.003 drivers then be shore - there is no difference between my ROM and the official Acer one.

In your step1:recalibrate all batteries. I just want to know how to recalibrate the battery?
I remember that the system can recalibrate the battery automatically from maybe WM6.1 or newer core...

well these roms are not recalibrating automatically as they should

yes there is a difference. new builds brings new improvements/change towards many features including power management. i am sure you have been around long enough to have experience improvement in kernel and memory management as well as power management.
driver 303c was specifically made for the old builds. not 6.5.3. so i guess the best way to be sure about the battery issue is to recalibrate. it is safe and it is free.

Yes, you are right. If the battery isn't functioning as it should - then it is best to recalibrate the battery.
But normally this won't happen if you first full charge the battery when you buy a phone and then turn it on.
thanks
brainmaster, nice rom by the way, thanks for cooking. i'm using one of your rom now, i recalibrate and getting a good battery life good battery life.
next order of business - waiting for someone to compile a linux kernel!!
hahaha

set backlight to maximum
turn off powersaving
let the device run until it dies by itself
take out battery for 10 seconds
put it back in
turn on device
if device turns on - let it alone until it dies again
if the battery have fully discharge, hold the power button red led will blink
once you know battery is fully empty, you can
a. charge using the original acer desktop charger
b. charge using a phone with stock rom
c. charge using your phone (make sure phone is off until fully charge)
wait till green light. then you're done.
the premise of this.
1. every battery has a chip that tells the phone and power management system that either it is empty or charged (voltage level, temperature etc)
2. Flashing custom roms abrupts this transaction of info from battery to power management causing innacurate reading.
3. new base driver will detect different battery level, some are ok and some are not, unfortunately in my case it has a serious error.
4. recalibrating is just a remedy to make sure that both phone and battery starts reporting on power drain from 100 - 0
one more thing, if you think your phone is affected, charge at a minimum of 8 hours (sometime the green light will come out earlier due to the fact that it is not accurately reporting the battery charge)

[Q] Wrong battery %

I have a HTC HD2 with the 2.2 froyo android.
A minute ago my phone shut down because of an empty battery.
When I rebooted in win mobile it said that the battery was empty as well.
So while charging a booted into android and in android the battery seemed rather full. I started Battery Monitor and it confirmed that the battery was 70% full.
So something is wrong in android???
Also i've noticed that when you boot to android while charging android says (when it is booted) that the battery is discharging. If i release and put back the usb-plug is changes to charging. But this might be a bug which is already fixed??
