SD power source - BT power source - JAM, MDA Compact, S100 General

I own a i-mate jam (updated with rom 1.12.04 ITA). When The battery power go down 10% i get following message (i traslate from Italian)
"warning: SD/MMC
residual power insufficient for selected divice to work. Close some active functions or connect AC Power adapter for recharge battery and tray again"
Consequently when the power go down 10% i can't use all programs i istalled on sd card.
Before i owned an Hp 1930 pocket pc and i could use sd card under 10% of battery power also.
Same thing with bluetooth: i can't use it under 10% of battery power e consequently i can't use bluetooth headset.
is that a malfunction of the i-mate Jam ?
and is there some workarounds ?
Thank you in advance for the answers.

It is not a malfunction, but a security feature. When going low on power the device turns off those devices to reduce power consumption which will enable it to keep the data in memory for a longer time. This is something conceived for the regular users wh install their stuff to memory, not for power users like us who keep progs on SD etc.
There is no workaround I have have heard of, and the topic came up quite some times here.
Consequently when the power go down 10% i can't use all programs i istalled on sd card.

The best way to avoid this (and do good to your device) is to recharge more frequently. I don't know about your usage, but with the batteries in the Magician it is thought to be better to recharge once the battery reaches 30%-40%. That is supposed to give the longest battery life.
So, if you can recharge more frequently and do not let the battery drain that low. If you are on the go for long periods of time, consider investing in a new high-capacity battery or get a second one so you can change them.

for psych0t1c:
Thanks for your answer.
I know it's better to regharge battery before it drain that low, but as far as i know, the more you recharge your battery the less it lasts.
Besides, even if you own a high-capacity battery, it can happen anyway to remain with a flat battery and consequently without all programs in sd.
Consider that i do all my backups in sd card, than when i remain with low battery power, i can't do any backups.
Finally i can't even use my bluetooth headset.
For all those arguments i would have sd and bluetooth at my disposal even below 10% of battery power.

This is true for NiMH batterys, which are pretty old tech and no used in cellphones and PDAs anymore. In those you had a memory effect. Current Li-Ion or Li-polymer batteries can actually lose capacity when drained so low. It is usually suggested to recharge them when they go below 40% that way the battery will keep the full capacity for the longest time.

It seems that this is not possible... I have not found any kind of hack or solution. Vijay talked about planning to take a close look at it, but I have not read anything about it since...

Very very Interesting web site.
You are right for the li-ion battery charge.
I didn't know it.
Good thing to know.
Thanks psych0t1c.
anyway, if someone knows any workarounds for my problem, any suggestions are welcome.

Didnt read the batteryuniversity page but there is no memory effect in Ni Mh.
Memory effect was in NiCd batteries.
Li Ion is preffred due to 2 reasons -
1. Power to weight ratio
2. Life

High capacity battery.
Hi,
I have an O2 IIi, with a 3600 mAh and I can go for more than 3 days with it.
When I get to 10% of the battery I can for more than 8 hours. Stand by, and maybe 40 minutes talk time.
Isn't there any registry hack to modify that 10% ?

It would be great to be able to change this to maybe 2 percent as my universal is often out of battery when i get to it and i have to wait a long time before i can listen to my music. Surely there is a registry hack for this one.

Is the advertised battery life correct ... because i cant seem to get anywhere close to the standby stated hours. Is standby mode equal to shutting off your magician [ie. red button on right side]?
Anyways, with the screen on, but the backlight off, i can only get roughly 5-6 according to my battery indicator [battery pack pro]. Its even less if i use the pocket pc to play music
Just wondering if this is the norm, or should I try to get a new battery? Any tips to conserve precious battery life ... aside from dimming backlights?[/quote]
standy times are always absolute BS, no matter what phone they're plastered to :wink:
mine gets about 2 days use with few calls, about an hr of mp3s and perhaps an episode of the chaser's war on everything.

damn, thats awesome.
(1) You just using the main battery? or do you also use the backup internal battery as well?
(2) How frequently are you charging? I mean, do you wait till you battery is low after 2 days to charge? or are you charging it every so often during those 2 days of use?
(3) What kind of battery indicator software or program are you using [if not the one already installed in settings/system/battery]?
(4) Do you leave your screen off or on when you arent using it?
...mine: 9 hrs. wmplayer playing with screen off and 1½ hrs internet browsing; standby? why should i?
Now i bought a 2400 mAh battery instead off 1200 and indeed it's doubled now...
(1) which backup internal battery?
(2) i'm charching as soon as it's below 10%
(3) i use batterymemstatus including overclock
(4) i prefer shutting off the screen especially to prevent touching any button by accident...

1: Just the main battery, the standard 1200mAH that comes with the Mini. btw you can't actually 'use' the internal backup battery - thats just there to prevent the data in your main memory from being wiped out if your main battery goes dry!
2: I usually charge when the battery drops below 20% (ie. the first 'low battery' warning) as if it drops below 10% then certain functions are disabled (accessing your SD card for example )
3: Resco Today Plugin, comes bundled with Resco Explorer. It uses the built-in battery monitor anyway, like most today screen battery monitor plugins.
4: Off. Backlight switches off after 30s of inactivity, screen off after 3 minutes, but I usually press the power button before I slip it back into my pocket.
I use PocketMusic for mp3s, which switches the screen off automatically after 30s (but still keeps playing!), and TCPMP for video - my videos are all encoded in XviD, which requires significantly less processing power than WMV (in TCPMP anyway) while keeping a good compression ratio, meaning less battery drain.
By the way! Make sure that in Settings > Connections > Beam that your PPC isn't set to recieve incoming beams... that can have a noticeable effect on battery life.
This weekend, when my battery got below the 25% mark after a long time of keeping it always between 40 and 100%, I noticed that my device suddenly went black while playing Sudoku.
After 1 minute I could switch it back on, presenting the boot screen. No data was lost. However, as soon as it gets to log on to the cell network, it would shut off again. I had to charge it to at least 30% to be able to get a cell connection again.
Would this be a sign of a dying battery?
Unfortunately yes, it's the start of the death spiral. :?
Mine was worst; my Mini would shut off suddenly at around the 40% level. Upon closer examination of the battery it appears a little bloated in the centre, so I guess all that accumulated heat from charging did kill my battery eventually.
I changed a new battery a few months back and could now go as low as 3% before the device shuts off.

Hey Krinkiespijer,
Where did you get hold of the 2400 mAh battery? Are they expensive?
Cheers,
James
I would bet ebay. ebay.com.au used to be swarming with 2400mAH batteries but they seem to have disappeared .
They are a bit pricey, but I still see a couple of them in ebay. But remember that they're quite large and your Magician wont fit into the stock case.
Also, try tools such as Pocket Hack Master which allow you to underclock the CPU, consuming less power. You can also use em to set CPU speed based on process usage.

Recalibrate WM6 For Mugen 3000 mA Battery

I have recently purchased a Mugen 3000 mA battery. I am thrilled with the extended battery life after fully charging and discharging it three times as recommended by the manufacturer. What I find annoying is that WM6 no longer gives accurate information regarding remaining battery strength. If I run the battery down to 2%, remove the battery and restart WM6 says 37%. At 2% I can repeat and WM6 still says 37%. After running down to 2% a third time and repeating WM6 says around 10%. After that it varies a bit but you get the picture.
What I would like to know is if one of you geniuses out there has discovered a registry edit, hack or 3rd party software that will provide accurate battery info so I don't have to be distracted by having my battery say 2% for hours on end or repeatedly remove and restart.
BTW, BatteryStatus Ver. 1.04.200 beta2 build 0173 reports the same incorrect info and so does SPB Mobile Shell 1.5 Home Tab.
Thanks in advance for your informed guidance. OK, that is laying it on a bit thick but I always highly recommend this site to anyone I know interested in really learning how to take full advantage of that little computer in their pocket.
Take a search on XDA for Ariel monitor maybe it solves your problem.
Thanks for the suggestion. It is a nice little program but it suffers from the same problem. I suspect I need to find a way to change the mA capacity WM6 bases it's battery calculations. I don't know if that can be done with a registry edit or if there is a third party battery monitor that has an option to change the battery capacity for calculation of percentage remaining or better yet auto detects the actual battery capacity. Ideally it would be able to both accurately read remaining percentage and make reasonably accurate time remaining estimates based on current and historical battery drain data.
It is like driving a car with a broken gas gage. Sure, you can use the odometer to estimate how much gas you have left but you are always worried your estimate is off and you will be left stranded without a phone ... oops crossed metaphors.
How do the rest of the users with extended batteries handle this irritating situation?
Bump. I can't believe i'm the only one with this problem.
I know this problem also i will wait with buying a high capacy battery until i find such a hack
The Kaiser uses a smartbattery. The battery capacity is based on the information that a small processor inside the battery tells the phone's main processor. There are several things that could be the problem:
1. The small processor in the 3rd party battery is programmed with the old specs for the standard battery. The is nothing you could do about this.
2. The small processor needs to be calibrated. You would do this as follows; set your phone to never turn off no matter how low the battery got. Now, run the phone down until the thing dies from lack of power. Then charge it all the way up. This should fix that issue. I don't recomend doing it many times, because it is not good for Lion batteries to be fully discharged too often.
This is a very valid issue which I have faced many times when using a 3rd party extended battery with other phones.
Not sure how to solve it though, although I have the 3000mah on order myself.
I think the battery reading is given by the battery itself, and most of these 3rd party manufacturers don't really care to put a smart processor in the battery (to reduce costs/make it smaller/etc).
I have the exact same issue and although it is a nuisance, I have found a workaround to keep using the phone. Simply physically removing the battery and replacing it will increase your remaining battery power substantially. I normally wait till the first low battery reminder to do this. Also, how do I set the phone to never turn off no matter how low the battery gets? This would also be fine with me.

I didn't run into this issue until I reflashed my ROM to one with W6.1. Then, rather than get 12-13 hrs with my 3amp battery, I'd get 6. I used my original battery, but when I put the 3amp back in, I still had 47% left.
It's the ROM, and until there's a fix, it would be a pain to pull and replace the battery just to work around. I've done this several times recently when I'm on battery power, but I'd rather not.
Anybody heard of any other fixes, outside monitor, or do we wait until we get a Windows Mobile 6.1 fix?
Still no luck?
Hello,
Has anyone been able to find a solution for this. I am ordering the extended battery today. I will try to fully discharge it and then recharge it as was suggested and report back.
I emailed Mugen. We went back and forth with them trying to troubleshoot whether it's the battery or OS. They were clueless, but did offer an RMA to replace the battery. I pay the postage. Not sure if I'll send it back if it's the OS. I pull and replace the battery right now. It's a real pain, and I hate opening the case so much, but it's the only way I can get an accurate read.

The processor is required for these types of lithium ion batteries because it regulates the charging of the battery. If it didn't the battery would not charge properly, or maybe not even charge at all.
There is no solution for now, people from other forums tries to patch battdrvr.dll.
But two things may help a little:
1.You may completely disable battery monitoring
HKLM\Drivers\BuiltIn\Battery rename or remove string battdrvr.dll
But you lost monitoring completely.
2. change HKLM\Drivers\BuiltIn\Battery\Order change value from 15 (in my case) to 0. - After this battery lasts longer until power off.
There is not complete hardware or software solution for this problem. We need to wait.
Low Battery warning:
By default, a PPC will sound a warning sound when the battery is running low (10%, fixed value), but there's no way to disable or change the notification. To enable this, so that it is visible in the "Sounds & Notifications" control panel, set:
HKCU\ControlPanel\Notifications\{A877D663-239C-47a7-9304-0D347F580408}\Default = "Low battery warning" (REGSZ string, no quotes)
Anybody have any updates on this? I have noticed this more on WM6.1, but it was still an issue on WM6. I just find this so annoying!
Is there any radio that can fix this? I noiced that this battery reading issue only occurs when the Phone Signal is on. When off, it never happens to me. Or it seems. So it has something to do with the radio.
bump, anyone got a solution?
this is very interesting, i bought the seidio 3200 battery i am having the same problems. i just tired the
change HKLM\Drivers\BuiltIn\Battery\Order change value from 15 (in my case) to 0
i am going to see how that works out throughout the day
Tried It
I am having same issue, reset the registry key to "0" and ran for a full day, no change, still incorrect reading. I have a 2700 Mah battery and the charge indicater is completely wrong on it. I have cycled the battery as per reccoemndations, but still get wrong power remaining readings. Can remove the battery and resets itselft to a more correct reading.
I am out of ideas, guess we need someone from HTC to chime in with a hardware fix.

i have tried it too and it still does the same thing. i would still need to pull the battery and restart the device for the batt meter to get a more accurate reading. i could do it about 3 times before the battery dies completely.
is there this problem with all extended batteries or just with the larger ones?
the reason I ask is that I've got a $17 credit at Amazon and was thinking of grabbing a 1600mah battery, it's only like $22 with ship so I'll only pay a few bucks for it really...
I wanted to get the larger one but it's fat and won't fit standard carrying case, but the 1600 is slim and will fit in place a regular battery

Bad Battery! - Possible cause?

Hey guys,
First of, YES I USED THE SEARCH FUNCTION .
My battery life is absolute horrid right now, and I tried everything.
I tried out different roms, every radio, deleting programs, hard resetting tons of times. I even bought a new 1500 mAh battery but it was still crap.
Battery log says my device in standby mode with the screen turned of uses -70ma, when I turn my screen up it jumps to -320ma, and when idle on the screen for a few sec it goes to -200 ma, but when I browse through stuff again it goes to 3xxma again. When I surf on the internet it picks up to 450-500ma.
Now, this morning with the 1500 mAh battery fully charged I played a few games of XTRAKT, few texts, 1 hour of music listening and 10 minutes of being on Opera through a HSDPA connection. It was down to 45%.
This isn't the normal rate the battery goes down at right?
I use HDtweak to manage my connection and put it off after a minute so it isn't that I keep dataconnections open. I never use bluetooth or wifi either.
Could it possibly be that it's the charger of the device? I perhaps have the feeling that it doesn't put enough juice into the battery even though the green light led goes on to indicate it's full.
Some feedback would be much appreciated cause it's put me on the edge of selling my device, which would be a shame cause I'm really fond of it (except the battery ofcourse ).
Thanks in advance!
/a
P.s. I am from a pda background, so it isn't that I'm expecting too much of the device or comparing it to a normal cell.
May I ask what you searched, as there are 3 or 4 active threads on battery drain right now?
Hi
Had same problem.
Try to browse a storage card if its very slow You must format it and it will back to normal.
very strange but its working.

Hi Antrak,
Touch HD has the longest battery life of any similar 'phone. See e.g.
http://www.pcauthority.com.au/News/1...-the-rest.aspx.
Either your battery is not charging correctly, as you say (try it via the PC USB cord?), or you have two dud batteries in a row (very unlikely) or you have a bug in your m/board. 70mA in standby is too high. It should be <20mA with only the 'phone on in standby mode, providing you are not moving from one cell to another all the time, and have decent signal.
One other suggestion. Drain the battery completely to zero, then recharge it to max. This should reset the internal battery meter. But don't do this too often, as it ages the battery faster.
If none of these work, return the 'phone for a m/board replacement undere guarantee.
I have the same problem... After charging for 10 hours, my batt shows 55% only.. and last 1hr on STANDbY!!!
IMAGINE! charge for 10hrs juz to get to use for 1 hr.. im disappointed by the batt.. im not sure if HTC is gona let me exchange with a new one or do I have to buy a new batt..
try check your sync..its active all the time or not..
if yes..
find the threat to make a fake account for sync, so you can active it manually.
so your battery will stand more longer,
about charging..
me also facing the same problem..
need to change it more longer to get full battery,
but
if i change in my car,
no issue
very fast
i thing charger issue..
but i bought original set..
??????????????????
Okay I've charged my HD through my pc with a USB cable and formatted my SD card like a other user said. Gonna see how it holds out today. It could very well be that some chargers have issues.
My experience with the Touch HD says that when charged with a USB attached to a computer the battery life is a lot shorter than charged through a wall socket.

Indeed, here's an illustration...
Image1:
Charging via USB takes longer. Consumption and therefore charge current is erratic after the battery level reaches 50% when charging via USB on my HD. So the battery fills up to about 60% of its capacity by the time when the battery level is reported to be 100% and charging stops.
Image2:
When charging with an AC adapter this is not happening and the capacity is fully utilized. This is also quicker.

That's strange. For me it's quicker if the device is turned on. When it's off it takes around 8-10 hours to charge but when it's on it's alot quicker.

hmmm, I don't know how this is possible?
If your device is on there is always power outage especially with programmes running, whilst if your device is off, there is no power drainage so device should charge quicker.
What rom are you using? software installed?

Latest official rom with alot of software installed. But it doens't make sence to me either. It's logical for something to charge faster when it's using no power (off) then when it is using power (on).
Combine battery threads ???
Hi to Moderators,
There are now several threads on the HD forum on battery and charging issues.
Can these be combined into one place and stickied, so we can get a clear picture?
Current threads are this one, plus:

I have a gut feeling from what I'm reading, that HTC have had a bad batch of batteries or charger circuits in the HD - in which case the best starting point is to call their service points and ask for help/replacement, instead of spending lots of time on other remedies. The symptoms described have lots of commonalities, and the HD is normally an excellent beastie for battery usage.
Thanks for all your help, ladies and gents! Your work is much appreciated.

Heya,
Don't know what it is but my battery life increased a tad. Am running Dutty's X3.0 with the 1.32.x.x. radio. Watching a 1 hour xvid dvd rip (no conversion) in coreplayer on full backlight with no HSDPA on, wifi or bluetooth takes away 20% of my battery, which is acceptable.
Don't think it's the SD card format though, it might be that I never have the activesync process on anymore by setting it to manual update and closing it (it otherwise keeps running.)

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.

HTC HD2 Battery drainage?

Hi
Battery problem, keeps draining quickly, just by leaving it anywhere. I charge the htc hd2, after not much use... the battery looses charge? I have s2u2 installed any ideas why this would be?
In other words, battery is on 100%. I open it using s2u2 and close it, just random play aroung with the phone. Next minute you know the battery is going lower and lower in matter of minutes. Thats with no phone calls, few text, no music, no games played i think your getting the gist?
This is wierd? anyone else experience this?
Please can some help and advice in the right direction.
thanks.

Try a search as there is a ton of stuff about how to treat the battery in order to get the most out of it.
hi pa49
I have looked at soo many post on xda, but i cannot get to to the bottom of it?
1. Is there any post you might note of, that could possibly put me in to the right direction?
2. also any place you can get extended battery (not the big fat one lol)

you may want to install battclock and check what0s your cpu usage, also disable s2u2, check differences, and whatnot... the only way you can find if it's a software problem or not is by checking with a clean rom.
Usual old boring advice, backup and hard reset, test with nothing installed, if there is the same problem of very high drainage, it's basically a good chance you need to send it back for warranty
I have exactly the same problem. Suddenly yesterday my phone's battery drained and I found my phone switched off, out of nowhere. I charged it for 3-4 hours, and then played some games, the battery was left at 85% and when I woke up today, after 6 hours, it was off again.
So you are suggesting to perform a hard reset and observe the way the battery drains?
Ok, First get the battery working at max capacity by charging it non stop for at least 2 weeks. Whenever you can and wherever you can for as long as you can.
Once you have done that there is a battery monitoring capability built into the charging circuits. You could then allow your battery to drain to cuttoff and then recharge to full again which will accurise the power remaing readout. I never bother with this step as I just use the phone and then recharge as soon as I can again, but, if it's important to you then go ahead, but, don't continually allow the cutoff point to be reached as this will damage the battery.
Now you have maximised the capacity of the battery see how it performs and assess whether you need to take further action.
Installing apps to mem card will eat battery.
Some say leaving apps open will drain the battery. I'm not too sure, but, it's good practice to close them any way.
Finding a clean and pared down cooked ROM will save a lot of power, but, you will have to do your own experimenting there.
After that you could invest in a spare/extended battery, however, I would suggest an external rechargable power pack (Have a look at the juice bar solar pack as it will recharge itself without needing a power socket or USB port (although you can use them!), purely by sunlight. Another advantage is that if you change your phone you still can use the pack with your next device and they will also charge many other devices!
Good luck!
I have my new hd2 leo, and battery seemed to be the main issue for me cause it couldn hold 1working day... but as everybody told its nessesery to charge 1 week to exercise battery for its full potential.. but i did some improvements, did the registry thing with dissablepowersavings dont remmember where found that, and instaled wmpowersaving, for control of 3g 2g data, using 2.12 radio rom, witch is more stable than 2.08 cause i use hd2 for a lot of browsing, and 2.08 was freezing my device.. 2.12 is stable and seems using much less power, i can feel less heat in the back of the case.. tried android... but that was not intterested me... i dont need those 1000ds of apps i need to browse the internet using iris browser.. and now battery easily can hold 2 days with some wifi 3g browsing.. and few phone calls some usage of camera.. witch is poor in dark conditions... so i think battery life is 2days ... and control the 2g 3g networks, turn off location service, turn off data connection.. and the battery for today evening is still 72% after 10 hrs of few phonecalls and a bit browsing with wifi.. some gps navigation i dont even think to buy expanded batery cause i dont like the BACK BIG CASE ... Also i wonder how much power is nessesary to run Micro SD built in card reader... because its a pitty to have 180mb internal memory for progams... if it had 2gb then u install everything in the memory and dont use the sd card reader witch i suppose will save couple of hours of battery.
this issue has been well documented..imo the stock rom battery life is awful lasts up to 24hour on casual use for me..there are cooked roms with better battery life or you could invest in a bigger capacity battery from htc or third party ones on ebay
There is a known issue with the HD2 and microsd cards, when the microsd's filesystem becomes corrupted, causing battery drain.

I just popped out my sd card to see if it is going to see how my battery does.
I will post my conclusion tomorrow.

Oops,
Sorry, I did not really notice any difference with the card out. I am currently trying it again just to be sure.

Ok, so I did a quick test, I turned off the radio just to take that out of the equation.
I ran for two hours, first hour with SD card out and then an hour with it in.
From the log, you see that I am about 6 to 7 mA up until 0945 and then it started to cycle, I dont know why, the phone was in standby the whole time.
I put the SD card back in at 1016 and opened explorer just to access it once.
the cycling continued for like 30 min then settled back down to 6 to 9mA.
So, it looks like the currnt is a few mA higher with the SD card in, but I have no idea why the phone was sucking over 150mA in those four to five reading bursts when I was not using the phone.
What do you think?
Jeff
