Battery: normal behavior or hw\sw failure? - Shift General

Hello!
I noticed very unpleased behavior of my Shift and I am wondering whether it is my Shift's problem or it is some common problem with some driver, for example?
I have configured power schemes to hibernate my Shift when battery level at 10% but it doesn't work due to (as I understand) incorrect information about battery charge level.
When there is around 40% battery level displayed my Shift suddenly turns off and it looks like battery is fully discharged.
First point is that it is boring... I really don't have any idea how long my shift will be working when I am at the meeting and also such sudden power disappearing it is not so good for windows and for hardware.
I thought I can use some "battery calibration" feature which usually present in notebooks but I can't find it on my Shift.
Does anyone have idea what to do with it?
Regards,
efrost

1. poor battery
2. You must setting bios or restore Windows

My Shift is 2 or 3 weeks old (I suppose that battery also should be 2-3 weeks old...).
Not really understand about the bios. I didn't found there anything I can use to tune somehow the battery.

I see here already 45 viewings... Friends, if you don't have such problem, just drop here a comment that you don't have it, so I will at least be sure that I should go to a service with my Shift.

I bought a second battery for my shift and it when it got to 10%, it suddenly lost all power and powered off. (It wasn't a power saving action). My original battery didn't do this, and gradually dropped to 5% at a normal rate.
So I think it's down to the battery.
Maybe time will calibrate the expectation of the batteries behaviour, so the problem will be calibrated away.
Although this calibration will have to be shared between two batteries in my case, so I guess the calibration will never be perfect for either battery.

I don't have any problems with the battery behaving as you've described efrost. Can I ask how long it takes to get to the 40%? IS it giving you the full 2 or more hours of use when it shows 40%? If so maybe it's a calibration issue with the s/ware? I have noted my bettery is performing better now than it did the first week. Like most I guess it has to be conditioned over a few cycles of charge/dicharge to reach optimal. I'm getting around 2.5 to 2.75 hours web browsing/odd email on wifi (strong signal tho) before it hibernates.

Just measured running time from 100% charged battery to the suddend turn of it was just one hour. :-\ Just before it turned off Windows was showing 56%. Then I plugged it in and turned on... now Windows is showing that battery fully discharged.
Looks like I should send my Shift to a service centre.

Apart from the fact no two compressed Lion batteries have the same exact specs ( Manfs are pushing the sp here!) We have what we have!!
Just 6 years ago I thought constant use of playing a DVD on a laptop for 2 hours was good!
You cant compare this to a Winmo device with the hardware included, until someone comes out with a mini Naquater genertor for these things, we are stuck with SIZE+INCLUDED TECH is inversly square to Battery life!!!

My wizard battery only lasts half a day now?!

Hi, my batter has been working great since Christmas, but now for some reason won't last more than a fwe hours without saying battery low. I have my gprs check email every 5 minutes, but it has always been that way and I have been gettnig a good 2 days out of my phone before.
Now i take it off of the charger in the morning and then around lunch the batter is low already...
Is my batter just toast?
Should I get another?
THANKS!
T
Just a question, but have you been overclocking your TI OMAP processor? Maybe there's a correlation?

Mine is brand new (tmobile MDA) and when I enabled 802.11g I noticed a dramatic drop in battery life. I think for the sake of the battery I will only enable that as needed.
I wonder also if you are in the same proximity to the mobile towers, if you are on a border between coverage you will see a drop in battery life becuase it is transmitting more frequently to register with the mobile network.
To try to see if its your battery or something you are using, and while this may be incredibly difficult with a mobile, especially a mobile/pda that you use frequently, you may want to see about turning off features to see if that helps. Turn off wifi and see if that helps, turn off bluetooth and see about that, etc. Once you rule them out as the major culprit ...
While I highly doubt this may be the case, it is a possiblity, and worth looking into, especially if you noticed a sudden drop in battery life as opposed to a gradual diminishment. You may have some rogue software that is sending out more data via a wireless device than you desire. A worm, trojan, whatever. There are anti-virus packages available, I dont know how good any of them are, http://www.freecabs.de has some, some of the big commercial guys make some. Again I dont think its that becuase of the rules of probability, however it is possible and some have been known to exist in the wild for a few years now.
T,
I had the same thing with my c500, now I know they are two entirely different phones but after I flashed the device it was as good as new in terms of battery life.
It may be worth a try before you go and buy a new battery.
Marc
I have the same problem.
Not overclocking, no anti-virus, just regular phone use and my battery does not last a day!!
I keep it on charger most of the day to avoid shut-down.
me too
I've the same problem and I've an other big problem, when I turn off my Vario, it's dont't start on power botton (i must extract and insert a battery turn on the telephone).
We can make a test if anyone have a HTC diagnostic software (see service manual.pdf)
Check your today screen.
I too had the same issue. Mainly, PhoneDashboard was causing the battery drop. Along with any today elements that poll your hardware to display the amount of battery, memory and storage. Those all drain your battery.
To check whether it's really a today screen issue or not. Charge your battery to it's full 100%, remove ALL today screen elements, then use your mobile normally and keep checking the battery level drain rate.
Hope this was useful.
Mine dies, 100% when leave work, some usage and then dead in the morning.
I only have Pocketbreeze and a few plug ins installed.
There is NO wireless /bluetooth in that time.

nope.
I have not been using wifi at all lately either
I have spb today stuff but have had them since I first got my wizard. really, I have not changed anything....
some programs "eat up" battery life. Investigate by doing a HARD reset, then do not install ANY software for two days. I bet you will see your normal battery life ;-)
I took all today programs off
100% at 5.30
32% at 7.30
This is O2 Mini Rom without all the 02 crap.
I will investigate further. Hard reset here we come!!
Last night my battery was 100% at 5.30 after a hard reset, no o2 software installed and very light usage.
This morning at 7.35 it was 50% which is good I guess???
Suggestions as to whether it is the battery?

Still not good enough, should hold for 3 days if you do not use it. Get a battery replacement.
Typically I charge every other day, little phone talks however.
PhoneDashboard was causing the battery drop

Ah, I run this. Is it bad? I've turned off all the scrolling updates etc - did you find that helped?
Got a battery replacement but still after no real use dropped to 50% in only 13 hours.
Any other ideas?
mine works for about 5 days normal usage with this options:
- phone on
- bt off
- wifi off
- automatically receive IrDa incoming... (Connections ->beam...)
so the wifi on my batt only last for a few hours, but when you disable wifi and the irda incoming you should have more batt. life
Thanks I will give this a try and have taken out irDA.
However my figures were with Bluetooth and Wireless off as well
I have noticed that with wifi on (and particularly if I'm using it) the battery drops at a frightening rate. Whereas with wifi disabled (which it's been for most of today - first day since I've had the XDA that I've been busy working and so haven't been 'fiddling' with it at all ) the battery still seems to be sitting happily at 80% after around 8 hours.
Funny, I thought that if the phone was suspended, the wifi would be inactive, so the battery wouldn't drop. Appears that's not the case...
Do u have Spb Pocket Plus installed? this program sucked my battery flat in 1 day. I removed it and now its up 2 or 4 days depending on how long i have wifi on. Checking email every 5 min also reduces battery life allot.
goodluck
No pocket plus... My today screen just has phmtray, resco today, taskplus, and the pocketmusic plugin...

Battery drain

Trying to figure out 1) cause of battery drain and 2) poor power mgmt.
I had a fully charged phone yesterday at 5pm, leaving work.
When I tried to turn it on this morning it was completely, completely drained.
I have 4min timeouts set on the phone for backlight off, and 5min for device off when on battery. I had WiFi tuned off, Bluetooth on.
I did have Wayfinder and GPS active on the way home, and may have just turned off the phone. If I turn off the phone with Wayfinder active, would this continue to drain the battery, GPS reception is passive, is it not ???
How come the battery drained to such an exent, it took 5 min on a charger before it would even power up, from a full reset and WM load.
My old XDA would hibernate at low battery percentage, and still have a reserve charge to keep the phone content/settings intact.
Any views, suggestions.

When I first got my x1 end of last year, I found I only got around 6 hours out of a battery.
Now I get about 36 hours of normal use out of one charge. Including 1 hour of gps each day/ half hour of wifi.
What worked for me was to, reduce back light time to 10 seconds when standalone. I also found S2U unlock drained the battery, so I now use the standard unlock.
Also, ensure that no auto updates (only manual) are done e.g SPB weather, insight RSS etc.
I have also changed my battery to a Mugen 1800 mAh. This seems to have increased my time by around 25% on average use.
S2U2 no longer drains my battery, one of the old versions did and so did the old version of AE Button but they are both good now, I get min of 2 days and max of about 5 depending on load of use... normal use is about 3... (internet for emails and dling rss feeds and some reading of forums 1 hour, reading books/texts about 4-5 hours and listening about 2hours plus calls and texts is a normal day for me...)
GPS does drain your battery pretty quick though...

There is no poor power management in there.
It is all because of wayfinder. GPS is still active if you leave Wayfinder active all the time and it will drain the battery supoerfat.
Try closing Wayfinder and you will what I am talking about.
I found out that any Battery applications greatly reduces my (juridically - my wife's) X1i lifetime.
AFAIK to measure any battery charge you need to short circuit it for a millisecond or so and measure the current, not the voltage. When any Battery software does it (through the hardware) every few seconds your battery looses its charge faster.

I am running Home++ and its fairly decent as far as drain goes... I dont notice much more than when its not running...
Tks for all your feedback.
I am fairly ok with normal use and battery life.
In this particular instance the drain happened so fast, overnight, and I was not using the X1 at all. (or so I thought so).
So I am curious to know what caused the rapid drain, and why the X1 does not have a more controlled low power close down.

I have already explained. It was the GPS application that drained the battery, nothing else.
Just as a test try leaving it for as few hours running again and you will see.
battery drain
I do have the same effect. but I do not use GPS or wifi at all.
Sometimes it put the phone down, screen disabled and fully charged. No application running.
Next morning the battery is dead.
It happens about once every two weeks without any sign why...
My solution: I bought a desktop charger which is able to charge a second battery and simply exchange it, when this happens again.
Not ideal - but right now we seem to have to life with it.
do you have an old version of S2U2 or AE Button plus on your phone? And I have also read that batti used to cause drain problems... this might be the case with yours(?) if you have none of these installed then I am of not much help...
If u use Push email or active sync, Google sync Hotmail sync any Email sync on arrivel option ur battery will only last 5hours cause the phone is using mobile web at all times and constantly sending and recieving, turn it off an ur phone will last over 19hours with out charge... EG i turned my email sync off at 10am an the batt level was 60% didnt charge it till next day 11am when the batt levels drop to 20%
Is your X1 fairly new?
I experienced exactly this issue about a week after I bought my X1. No apparent reason for it, but the battery just drained right out overnight.
Strangely, the same thing happend about a week after I bought a HTC Touch Pro.
In both instances it has happened only the one time. Since then things have been normal, or drains caused by known software issues (like the buggy version of S2U2).
As earlier suggested, I loaded the Wayfinder app, with its GPS active.
I tuned off the phone when the app was on screen.
Left it for 3 hours, and there was a noticeable drain of the battery.
Lets hope the new WM 6.5 improves Power Mgmt, and has a more elegant low power handling.
Do you have G-Alarm installed? My Battery gets drained very fast when I have this installed. I tried many different versions within the last few month, allways the same.
I experienced this last night for the first time with my X1. I left the X1 on the bedside table at 11:30 with 90% charge and was awakened by the battery low alarm at 6:30 am (not good).
The only thing that I noticed that was unusual was that my X1 had been connected to the PC with ActiveSync in the connected state. I shut down the PC and then unplugged the X1. In the morning after the battery low alarm I noticed that the phone thought it was still connected. I use SPB Phone Suite and it was still showing the Cradle profile. This would not change in the automatic mode so I had to reboot the phone. Everything has been fine since.
So ... I am wondering if ActiveSync can sometimes go crazy and drain the battery more quickly??
I have a faster draining battery since i installed g-alarm. can anyone confirm that?
In my case I dont have G-Alarm installed.
Well my battery is not draining that seriously. it's ok i guess.
But maybe you should try what is suggested in the last post of this thread:

Battery does not charge properly when D2 is off

Hi,
I noticed the following problem on my Diamond 2:
If I turn off the phone for night charge it never shows green in the morning.
The only way to see that amazing green light is to charge the phone whent it is turned on.
Of course I applied the latest hotfix - no use for the off mode charging. And of course I wrote to htc - will not waste your time repeating their suggestions.
And I am not happy with my phone battery life - it hardly endures one working day - lets say - 10 hours...
ROM - Official, yet.

I never turn my phone off so the green light problem never arises. However I will check and see if occurs.
As for battery life, you will need to give it a few weeks of use before you see maximum battery life.
Make sure you don't continually discharge the battery (better still keep it charging whenever you can) and you should see improvement over time.
Unlocking and replaceing the ROM can also have a significant effect on battery performance as does the Radio version in use. That's going to need some work on your part but the improvements are there to be had.
Some apps that are in common use are also power hungry and can cause a significant drain on power.
And if you install your apps to mem card then again that uses more power than installs to phone storage memory.
You can also turn off any unused background apps and processes.
Only turn on Bluetooth and WiFi when needed.
All these things help.
Personally I carry a spare standard battery with me at all times and strangely since I bought it I haven't needed to us it. The placebo battery effect?
Thanks for the answer.
About the battery usage conseption:
You suggest that I plug my phone each time when possible?
I thought that as the battery has XX recharges according to the specifications it is not good to charge each time whenever you got AC or USB access
I started to follow your recommendation anyway.
For example however - my laptop is never (when possible) with battery in it. I use the battery only when necessary, becasue in the user manual is written that has 300 cycles of recharging. And I always wait until completely discharged before charging. That is how I began treating the Dimond, too.

With Lithium Ion batteries the "quoted" numbers of "rechage" is is an approximate equivalent to give some idea of life expectacy.
It's a hangover from the old NiCad battery days and is not really very helpful when applied to Lithium Ion usage.
The most important aspect of LIon is it's ability to hold it's voltge at max current for longer than other technology. It does this best when well charged and maintained at near max as possible as often as possible. The downside is it's life expectancy which does deteriorate over time.
If you require max daily useage then max charging whenever possible will give you this and you will have to accept that the battery will at some point loose it's charge retaining capabilities and will have to be replaced.
For most of us that's the most important thing.
This is not a battery issue, I believe that this is a software one.
I noticed this morning, having left my phone on charge, and 'off', all night, that the indicator light was still red. When I switched on the phone, it showed only 80% charged.
Having seen this before, I carried out a soft reset, the battery indicator then showed fully charged.
So the battery is charging fully, but the battery charge indicator is showing less than that.

Non-linear battery usage (@99% for 8 hours)

I have a non-urgent but pretty weird and annoying problem with my battery status. After charging (usually overnight), it sticks at 99-100% for most of the day if I barely use it. Once it gets below that, it steadily depletes faster and the last 10% is gone within an hour. The battery life itself is fine, for which I'm grateful! If I barely use my phone it will last four days or so and easily last a single day under heavy use. Strangely, if I reboot my phone, which I do maybe once a week, it suddenly ducks down to a more realistic number; say 50% before rebooting and suddenly it's down to 30% after.
Is there any way to fix the meter to indicate the true state? I can imagine there should be some way to calibrate it or I could even calibrate it manually if that's possible, setting the current 90% to 50% and 50% to 30% or so.
It might be relevant to know that I'm using Dutty's 4.3 Final WM6.1 ROM. Does anyone have experience with this or have ideas to point me in the right direction?
I am
I am using duty holy grail 2.1 win 6.5 with modified icons cab and i find that if it seems to be on a certain percentage for awhile i just soft reset the phone and it will drop 5 or 6 percent and start displaying properly.
My battery is similar although not as extreme. The first half of indicated charge lasts far longer than the last half. Also if i reset my phone the indicated charge will drop by around 20%.
It has done this since i've had it on standard Orange Rom.

I have the same problem!!!!!
Other thing I realized is the radio of my phone is always communication, i know that because if Iput my phone near a sound box (like my sux sound box pc) the box make a noise every 4 seconds, stop 10 sec and starts again...
Some one else saw it happen too?
Same battery probem...
Hi at all.
I have the same problem, the phone stay with aproximatly full percentage for 6-7 hours, but after these hours at hevery call the battery go down fast...
And, during the last 30% of the battery percentage the countdown is very fast....
can be possibile only 2 or 3 short calls, at maximal.
Problem of windows mobile software, or htc hardware...?
The battery meter inside windows have the same problem.
Best regards.
Luigi P.
Same issue here.
I believe everyone has it, but as battery life is generally really ok nobody complains.
Same problem here.
When a Battest runs in the background, then is the indicator at 80-100mA but sometimes it goes up to 280 for 20-30 seconds.
I don´t know if there a program which need the battery power or the indicator shows not correct.
I have this Problem since i updated the Radio Rom from 1.12.25.16 to 1.13.25.24.
When i backup the 1.12.25.16 the error is the same.

Battery Drain HD2?

Anyone else experiencing excessive battery drain on their HD2?
I am interested to know if this is just my phone or if it actually just chews through that much juice.
I have had windows mobile phones for several years so I know all the basic ways to keep battery drain down.
Stuff that I have generally found:
1. If I keep the screen turned on without it going blank I lose about 1% every 2 minutes.
2. If I am browsing that figure almost doubles.
3. My old Touch HD used about 5% battery overnight when in standby but this phone will go through about 25%.
4. The phone gets really hot when browsing (much hotter than my old Touch HD)
I have tried flashing ROM's and Radios but nothing seems to help.
I am not running any software on the phone that I wasn't running on my old HD1.
I have only had the phone for a week so I am not sure if this is normal but I would be very surprised if HTC released a phone that lasts for only a few hours on one battery.
+1
-1% every 3 minutes
-4% during the night (when i'am sleeping)
MAXIMUM : 45/48 HOURS

I wish I got 2 days
we really need extended battery ,hd1 battery was much more better.
Good mate but yes i agreee HTC has come up with a battery eating device this time around. My device on full charge just gives in around 8-10 hrs. This might be dat my EDGE is on and 7 mails accounts sending mails back and forth.
but truly i think that HTC better look into this very seriously cause more and more ppl are suffering in this battery drain..
Any of flashing roms and radio not helping either... did a complete hard reset but no step up
HTC come with longer battery battery for bigger devices soon......
The only solution i see now is get one of those extra battery worth mind bogling £52.87
I've had this problem ever since flashing to 1.66, I flashed the radio to 2.07.50.27 as this was said to solve the problem but it hasn't made any difference after a few days of use. My battery life used to be significantly better when I was on the original stock ROM, so much so I'm considering going back to it
I also know all the tricks as to clawing back the battery drain, my phone is idle on my desk at work most of the time and I don't use Wi-Fi, all the location stuff is turned off as are weather, stock and other updates plus my screen is set to 30% then off after 60 seconds. Despite all of that I lose 1% every 2-3 minutes
It seems to me that perhaps the radio is checking for reception pretty much constantly rather than say, 5-10 mins perhaps? This used to be a problem on my old Blackberry Storm but a few fimware updates solved it, eventually!
The only other thing I've noticed since the update is that once the battery drops below 50% or so, the drain seems to slow, I don't know if this is perhaps because the phone goes into some sort of semi-power saving mode?
Suggestions/hints welcome! I've had a semi-thorough look into this on the forums and tried most of the suggestions but still the problem remains. Will battery life improve after a few charges perhaps as this was a trait of my Storm's battery, the more you charged it the better the day to day battery life was (and no it wasn't because I had it plugged in all the time! Over time the general charge just seemed to improve when roaming).
Thanks!

You need to indicate what services you have running. Do you have any data services running eg: location services, push mail, weather? all of these have a bearing. In addition, network services can also drain a battery, especially if the signal is weak and the phone have to search for a transmitter, or 3g services.

That is a very interesting comment. Although since upgrading to radio 2.07.51.05_2 I have had very good battery life, I too have noticed a slowdown after 50%

You need to indicate what services you have running. Do you have any data services running eg: location services, push mail, weather? all of these have a bearing. In addition, network services can also drain a battery, especially if the signal is weak and the phone have to search for a transmitter, or 3g services.

Nothing is turned on, everything is set to manual.
As I stated I know all the basic stuff. I understand that all these things have a bearing on battery loss.
Everything I stated in the first post is for when I have nothing running. The phone is just sitting there running sense, thats all.
I have had my HD2 for a few days now. I am on Vodacom in South Africa.
I have not had a problem with battery life.
Yesterday i unplugged from the charger at 07:00. I spent about 1 and 1/2 hours of talk time on the phone, it was permanently connected to 3g doing weather updates etc. Sent and received a couple of sms's. Also played with a few tweaks and reboots.
When i got home at about 18:00 i had over 30% battery. I then surfed the web for over 2 hours to drain the battery.
try setting Network Selection to Manual

Anyone else experiencing excessive battery drain on their HD2?
I am interested to know if this is just my phone or if it actually just chews through that much juice.
I have had windows mobile phones for several years so I know all the basic ways to keep battery drain down.
Stuff that I have generally found:
1. If I keep the screen turned on without it going blank I lose about 1% every 2 minutes.
2. If I am browsing that figure almost doubles.
3. My old Touch HD used about 5% battery overnight when in standby but this phone will go through about 25%.
4. The phone gets really hot when browsing (much hotter than my old Touch HD)
I have tried flashing ROM's and Radios but nothing seems to help.
I am not running any software on the phone that I wasn't running on my old HD1.
I have only had the phone for a week so I am not sure if this is normal but I would be very surprised if HTC released a phone that lasts for only a few hours on one battery.

Same here with and without stock ROM.
yeah.. the phone is a battery sucker.... another cons of HD2....
This is very interesting to read because I do not have this problem. When I left my HTC HD2 on last night (I woke up at 4 in the morning to get something to drink and unplugged it) and then woke up at 8, it was at 98%. That means it went from 100% to 98% in 4 hours. Not to bad imo.
I am now at work and it is 15:34, and I am at 87%. I have made some calls, watched some videos, send a few text messages. Not much (I am at work so I got other things to do). So 08:00 (98%) - 15:34 (87%) - that's 7 and a half hours, with some calls, text messages and a video.
I am pretty sure when I get home at 18:30 the battery will still be above 75%. Then I connect to my wifi at home, refresh twitter, weather, browse the web a little bit, check e-mail etc. So that will drain my battery a little more.
But overall I have not had any problems with my battery life. I always make it trough a day, and never have a problem like 'damn my battery is almost done and I am not near a charger'.
Some info that might help:
I do not sync ANYTHING automatically. I still have some things to do with my Vodafone contract and do not have an unlimited plan yet. I only sync at home on my own wifi connection. For me this is not a problem, because I only need to refresh the weather each morning to see what the day is going to be like. Twitter I only do when I have the time. Stocks I do not use.
I have screen brightness set to automatic.
I am on 3G most of the time.
I am running the official 1.66 Dutch ROM.
I have some tweaks, games and programs installed.
I hope you all solve this issue, because it just can not be that my HD2 has a good battery life, and your HD2 not
Kind Regards
EDIT @ 17:00 still 87%.
I am in a 3G 2100 only network (I don't have 2G functionality).
ROM: Artemis 3.0
Radio: 2.06.50.23_3
Customization: Seiya 6.5.5
I don't leave any automatic updates on, except for my e-mail account every 2 hrs.
I never close my connection.
The drainage overnight is -3% (8hrs).
The battery lasts at least 12 hrs of intense usage.
Normally I have to recharge every second day (e.g. I charged last night, I answered a few calls, I did some IM and browsing and I still have 73% left).
For a phone with a 1 GHz processor, a 4.3" screen and a tiny 1250 mAh battery I find the drainage is rather decent.
Mind you, I ALWAYS do at least one full charging cycle to my battery after flashing a new ROM. I mean: full discharge, battery out 1 min, full charging in OFF mode, battery out 2 mins.

I have seen this process recommended a couple of times now. What is the theory behind it if you don't mind me asking?
maybe its also becouse some of us couldnt wait using the hd2 when they got it (like me) before it was fully charged for the first time
anyway my battery life has improved a little bit, i was at 74% this morning and did a lot of browsing, installing, tweaking and now its at 3%. it used to be much worse
I have battery consuming problem from time to time.I did everything:
installed new stock rom 1.66;
transfered all data which phone is using from card to phone memory(pictures,icons,sounds.etc...)
all updates are done manually;
Gprs connection is swiched off on the idle after one min;
One night it is loosing from 2 to 4%;
another from 30 to 40%
and it is eating memory from 10 to 15mb
I think that it is radio which is causing battery drainage so fast(to much communication wit a base stations,because when I am checking spb wireless monitor in the morning,there is no any data traffic.
I hope they can solve problem,because it is getting me mad and crazy
Try setting the screen brightness to 10-20% (on battery powered)
and dim backlight after 10 seconds (on batter powered).
It helps a lot, at least for me.

as far as i know, the battery has an integrated digital circuit (ic) which estimates the state-of-charge (soc). the procedure resets/calibrates the ic to obtain a more accurate estimation. since the radio rom is in charge with the power management (among other things), by changing it you decalibrate the "gauge".
i don't know if i've got the theory right but i tested this myself and it surely works.
