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!

Just to confirm, I'm on ChuckyDroidROM with mattc Leo + Froyo w/Sense 1.5b.
- I can charge to green when the phone is powered off.
- I cannot charge to green in ChuckyDroidROM WM (says 100 in Battery screen, just no green LED)
- I cannot charge to green in mattc Leo + Froyo
w/Sense (stays at 98 in Battery screen)
Hi i am on ChuckyDroid ROM 2.12.50 Radio and darkstones 2.1 build.
have don successfully the trick in post 1.
Now having 100% in the taskbar and i will report if the battery life have improved.
I used the search button, didn't find anything with my same problem (if it was alredy asked sorry)
Hi to all, I noticed that on my HD2 the only thing that drains too much battery is 3G connection...
It drains at the point that is impossible to charge the phone when the data network is on!! (tried, 2 hours charging, locked on 8% battery)
also.. the antenna gets hot.. it drains in the same way even if i'm in standby!
I'm just wondering... is there a way to modify battery draining? reduce voltages or something close to cpu undervolting/underclocking? I think it's draining even more power than it needs (in winmo doesn't get so hot and doesn't drain so much)
It's only my issue and anybody else noticed that heavy drain? please let me know...
my setting:
ROM: axlor leo v3 (it's android compatible, means no robot voice during calls)
RADIO: 2.12
ANDROID: hyperdroid v 1.6 (kernel michyprima as you can dl from hyperdroid page)
Bye
Are you using wifi? Once the phone gets too hot it will stop taking a charge
Sent from my HTC HD2 using Tapatalk
As already stated the problem is only 3g related, wifi doesn't give any problem, it drains battery normally.. The phone in stand by doesn't get so hot to justify the charge stop, it just drains all the power given by the adapter...

Sorry, but seeing the title of this topic I just had to do it.
Good one
But seriously, did you ever tried another radio? I got the same, but my HD lasts min. 1 day and when I charge it never gets hot..
That's not very good, did you tried with SetCPU and a profile that set the clock to a lower frequency when you charge? Maybe that will work..

Nice ^_^
@JanssoN what radio are you using?
Anyway it's only a matter of 3g connection, if it's turned off, battery can reach 2 days of duration (I use wifi in my house and use phone for texts and some internet) and there is no overheating even in case of charging...
When I charge the phon with data (3g, not wifi) on, it doesn't get hot, it just doesn't charge
any idea?

I'm using the same radio, that's why I think it's a strange issue.. Did you try to change the WM-ROM? Maybe that's the problem, I dunno, never heard about such an issue?
My Setup looks like this:
Radio 2.12.50.02_2
WM ROM Chucky Droid GTX Light with Android Bootloader
Mattc 1.8 with sense
Why don't u try to install SetCPU and create a profile that sets the clock frequency to some lower speed at chargin?
forum.xda-developers.com/showthread.php?t=734886&highlight=setCPU[/url]
Try and report back.
I have exactly the same problem, phone gets very hot on 3G, and battery drains quickly. On WiFi, everything's cool
stock 1.66
2.12.50.02_2
darkstone's DesireHD
Why don't you both try to upgrade on the new 2.14 radio? I heard that it should be very stable. You have to search, don't know which thread it was.
Will try as soon as I have time, thanks for help..
It seems to be android build/ROM indipendent as d4v0r has different setup and same problem... so maybe radio will solve
Ok, maybe this will work.
Sent from my HTC Desire using XDA App
solved (?)
Trying radio 2.15, it seems more stable, no high temps for now and battery drain is normal
Sounds good
tested for 2 days: new autonomy:12 hours of 3G on with applications download, twitter updates, web browsing, autoswitching from 3G-G-H and no signal at all.
Everything in "moderation" that is, normal use (for me)
No high temp.
So... try to update ^_^
3g shouldn't be exceeding what your charger can supply. Are you using the original charger and more importantly ate u using a cheep cable. If i use a cable that's can't cope with high currents you will draw power faster than can be supplied.
Been there. Had a replacement cable that when tethering with PC wouldn't charge.
If you don't have setcpu installed. For God sakes install it.
Sent from my HTC HD2 using XDA App
The problem (for me) is now solved, it was a radio issue. autonomy with data on passed from something like 6 hours or less to 12 which is good, maybe less time than other are experiencing but it varies from winmo rom to winmo rom i suppose.
SetCPU is my friend from the first android and it keeps my cpu to 768 max while in use and 245 max on screen off, i use ondemand governor cause conservative keeps the devices to slow for me
i also notice my battery drive fast....

Hi Harky, nice to see you here! Which Android ROM are you using, btw?
Base is Energy Rom
Using ★shubCRAFT 1.5★CM6 Final★
Radio: 2.12.50.02_2
Do ur rom drain alot of battery too
Maybe try this rom for one week and see how is other rom...
in the morning till now.. i notice i lost at least 30% battery. When i m standby mode and surfing a 30min net
Hi Harky, try the new radio (2.15.etc.etc) which for me made a great job
Anyway we still can't expect a droid build least the same time of a winmo build, but for me a day (12h duration cover good part of my day XD) is very good...
Next step for me should change winmo roms and try if there are differences...
If I'll do that, I'll post results..
I'm getting between 153mA - 289mA on standby.
This is a FRESH install on NAND. I was actually getting a little bit less drain when I was running via SD card with Coredroid (and the matching WinMO rom).
I've seen tips and tricks on how to lower battery drain when you're SD/WinMO...but haven't been able to find anything on NAND. My thought was that it was a lower drain then SD "out of the box".
setup
-wifi disabled
-bluetooth disabled
-GPS Diabled
-Autosync disabled
-Screen brightness all the way down
-Email push every 15 minutes
Can someone point me in the right direction as to where I can find some info on this?
Thanks
Do you have your phone plugged in when you are seeing these numbers?
If so...unplug your phone and see if your numbers change. When i am plugged into either AC or USB i see the same results...on battery power I get 2-4mA

Nope not plugged in. I get about the same readings pluged in or running on battery power. I've tried reinstalling current widget as well.
It finally dropped down to 2mA on standby a few minutes ago. Why such a rapid jump?
For me was this build laggy for the first 30-40 min.I think ther was running some initial setups..so could be the reason for your high battery drain
Sent from my HTC HD2 using XDA App
i have no more than 12 hours from 100% unplugged according to some small program from the market... charging over night in the morning it shows 0mA in the current widget... after a day use when i check the current widget history it says sometimes in standby 3-4 mA but usually stays at 15-20 mA (i do not know why)... no wifi, no data, GSM, no GPS etc...
Just so you know, when phone on charge current widget shows how much charge the phone is getting, so when its zero the battery is full I get 3-5ma in standby with everything off I recommend to everyone doing a full charge with phone off once flashed new Rom
It's full when led turns green
Please check out Projections thread on his new kernel for DFT's NAND build.
That should fix your draining issues. Though they are quite high in your specific case.
I flashed original rom but my battery behavior is still like on 2.3.5 RC4. Charge to 99% and drains very fast. Did someone know how to get back it original life. I tried battery calibrators from the market and battery wipe from clockwork mod but no result
If your optimus is old it is normal that battery life will get worser and worser ... All you can do is get new battery of ebay like I did and now my battery life is normal ...
Mike
It's not old. Its younger than a year. Battery life was good and on swift it last long and charge to 100% but after last time i flashed 2.3.5 rc4 i calibrate it (to try it last longer like on other roms) and now even on stock it drains like on rc4 and not charged to 100%
Use spare parts to see is there app that drain battery.
install "batterycalibration" from market, charge to 100% and calibrate your battery for this rom
Yes i download two battery calibration programs but the problem is that it's not charging to 100% but to 99% and drains very fast after this. i'll calibrate it a few days hope to fix
yeah, that happens to most people.
unplug, use a few seconds or 1min or so and plugin and wait if its fully charged, it could be that you have to do that a few times (2-3x)

Your not alone on this, same thing with me.
I have ordered another battery from ebay but dont really know why all of a sudden this just began happening whilst using the same Rom which I think has something to do with it.
I use a program from Market called Android Booster to terminate running programs that start up or dont close once started, as sometimes if you use your camera, it will be still running, even if you close it up so hence battery life turns crap.
But also, if somebody phones me for 5 minutes this also nearly drains my battery, and I have everything also turned off. (WLAN, Blutooth, Data, GPS etc).
So dont know why this is suddenly heavy on the battery as it never seemed to do this when first installed.
There you have it, your not alone but think I will migrate to another or buy another phone as I think its pathetic to have to charge one's phone everyday, or twice a day if you chat to somebody for 5 minutes as it defeats the purpose.

Try charging through the wall charger instead of through the USB port on your pc. Worked for me then, recalibrate.

I got my brand new battery and even charged it up via Power Supply from the wall.
Have run the phone only on 2G network only box ticked and everything else turned off (and I mean nearly everything) and for whatever reason, the Battery new or old still does not last long.
Even after it charges to 99% says its charged, it discharges very fast, or if somebody phones you and you only talk for 2 minutes the battery drops to like near 30% which is pathetic.
Something is sucking the life out of the battery folks with these Rom's so can somebody exactly put the food on the table here and say, whats up?

What ROM are you using? It takes some time to charge up the battery and even if it says '99%' that doesn't always mean that it is. What is the capacity of the battery? I'd say charge it for about 6 hours and see then.
Thanks Johnny,
Problem at present seems to be solved now.
Yesterday and before I had been using Mur4ik's CM7 2.0 RC4.
I then uninstalled a stack of apps that I only used every so often and now its like back to normal so I guess it must have been those apps installed.
Folks here is a big tip. Uninstall Apps to test your battery to find out which one is the Energy Hog because even if you are not using them, they seem to be running due to either bad programming of the app or a system management issue related connection between the two.
Now, I have just updated to Mur4ik's CM7 2.0 RC5 and will certainly think twice prior to installing a bunch of things for the sake of installing apps.
Cheers people~!
Hi all,
Hope you may have some ideas.
Both me and my partner have HTC HD2's, We share the same docking station for Charging etc. My phone, is sound as a pound. Has never skipped a beat.
My Partners one however, is causing a myriad of issues. the main one being now is Battery drain, even when the device is turned off.
Last night for example, It was in the doc in the evening - being on 100% when removed from the dock, put it on the nightstand, and switched if off... powered it up this morning, it only had 4% Battery!
We have swapped batteries, and this issue still occurs with both batteries, but only when attached to her device. I know the Cable is sound etc as we both use the same dock.
Does anyone have any ideas whats going on as its not a direct Battery issue?

Some info on system used (WM or Android) could be helpful, anyway as the first place to start I'd suggest using battery current app: BattClock (for WM) or Battery Monitor Widget (for Android), so you can check if the drain stops after disabling some system functions (like weather sync in WM/Sense),
I remember seeing quite a few threads on this here on xda, maybe searching the forum will return some useful links

The Drain on the battery is on par with my HD2 - as stated, its when the device is off (not standby) that the drain occurs.
The Drain happens on both WM and Android, but the OS is probably irelevant as it occurs when the device is switched off.

there's always a slight chance of hardware defect, or defective battery, but since there is no easy way of checking this (apart for switching the batteries on your devices), I'd rather start with checking the software side:
- monitoring battery current works perfectly for standby mode - the meter is updated at intervals (usually 1 minute),
- the first figure you see after turning the device on is the battery current consumption in standby,
- this figure usually should not exceed 10mA, if it is higher, especially in above 50mA, then it's the moment for checking with app/setting is causing the increased consumption,
- the steps taken now depend on the system used on the device, there are different things to check/uninstall/turn off under WM and under Android
Same problem

I have exactly this problem on my HD2 with android. I normally have my Sensation XE but now i wanted to make the HD2 to work smoothly and give it to my father in law.
I don't remember i had this problem before. Did you found a solution?
And as you said, the device is completely turned off, not "stand by".
Cheers!
I've had the same problem, with the side effect also being the phone randomly forcing itself into car mode. Might be a short in your USB port. Clean it and it might help.
Sounds like the battery giving up. Can you test another battery. They are cheap enough on eBay. Mine was not great got a gold business battery on ebay for it. Lasts ages now

Maybe it is a radio issue. When I flashed different radios on my HD2, some would give me bad battery life, and other would fix the issue.
