The Universal has no backup battery that I am aware of, and yet when the battery is taken out or swapped, the real-time clock keeps running. This is very useful, and I suppose it is powered for a time by the charge in a capacitor.
Can anyone confirm that it is a capacitor that keeps the clock ticking? Also, anyone know how long the battery can be removed before the clock eventually stops?

sorry, the Universal has a backup battery for the Clock

When the battery of my TyTN gets at 20%, I start getting system notifications warning me about a low level battery and others telling me to charge the battery like the manual says so.
The issue is that at 20% the TyTN still has a lot of life time, and meanwhile until the battery gets completely drained, I get MANY of these notifications that keep disturbing, it really isn't handy.
Does anyone know any solution for this? Maybe some way to start this notification only at 10% and maybe making them fewer.
It's only needed one or two notifications to remember us we are getting low on battery power, no need to keep reminding it all the time...
Thank you.
It's anoying me aswell...
I hope they fix this in the new ROM.
On the same general topic, anyone else find the battery status to be inaccurate?
I've re-enabled the small, four-bar battery indicator at the bottom of the home screen with a hack from MoDaCo.
Thing is, it's full most of the time - then wack! it goes to one-bar red and I start getting notifications. It doesn't seem very dependable. Anyone else get this?

same problem with me. looks like there is some serious bug with low level battery notification. in my case, i have Magic Button installed and i'm using its feature, which shows thin battery bar at top 2 pixels of screen (something like Batti). each time when i wake up my Vario II, this indicator always shows 100% battery for 2-3 seconds, after which it refreshes back to current state.
so this thing brings the idea, that these multiple notifications are caused because device 'thinks' that battery is full after each wake up, but after few seconds it turns out that it isn't, so system is generating notification - again and again after each wake up.
I've been having similar issues except in my case the battery is actually full.
The device powers up after being in 'sleep' mode (or sometimes during normal usage) and generates low battery notifications, even though the battery has been on charge all night and is actually full or at nearly full charge.
A soft re-set doesn't seem to help but physically switching the device off and on again seems to fix the problem (the battery showing 100% afterwards) but theres a definate bug with the power monitoring software
I really want to know how to modify registry of Hermes to avoid low battery notification too
Just a thought, on other devices such as the universal and breeze etc... (i see ive mentioned smartphones aswell as ppc) ... is the battery indicator shown in 10% blocks like the hermes or are they in steps of 1%?????
Anyone know of a reg hack or possibility that this will be changeable to 1% steps???????? (ROM change or the like?)
Ah yes, pretty irritating, guess we'll have to wait for the rom updates?

There is still no way to change the battery monitor to 1% steps.
From what I've checked, there is still no fix for this massive flood of low battery notifications. If anyone have any other idea... please share it.
My WM6 ROM show low battery warning at 40% - really annoying. I really just want to get of these notifications altogether!!
One possible cause of the battery showing that it is full only to have it drop 50-80% after a few minutes is that you are using a trickle-charger such as the USB cable to charge it.
When charging with one of these devices, when the battery says it's fully charged it usually isn't. You will want to take it off of the charger for a minute or two after it says it is full and then put the charger back on if you want to get a consistent full charge with a trickle charger.
Any news about the annoying low battery notifications?
I hate it and I would like to kill it forever...
Thanks

In s-k software's sktools there an option to allow it to show the low battery notification in the sounds and notifications. I find this very useful as i disable the message on the screen which gets in the way when it pops up to tell you battery is low. You can even change the sound or just disable the notification completely! Theres got to be a reg setting for it so people can use this little hack without buying the program.
Anyone know of a status bar Battery Icon that also shows drain in either mA or mW?
If not, perhaps someone around here might be interested in creating one as I have looked but cannot find one. (I do not mean a Today Plugin like HomeScreenPlusPlus/BatterStatus)
The idea:
Essentially similar to the WM Battery Icon that is there now with bars showing charge but with added feature of numerals showing mA drain. These numeral could either be overlayed on the icon or squeezed beneath it in tiny font.
The advantage of this arrangement is:
1) it would work with TF3D on a Diamond. This is because it would not be a today plugin. Simpy an alternative to the current battery icon on the Status bar.
2) Would enable user to always see charge remaining and current load.
I like the idea of always being able to see the load on my battery as often I have apps running in the background which are chewing through the battery. Conversely if the mA drain is low I know these apps cannot be running and all is good. Makes for an easy way to increase battery life.
Essentially all the app would have to do is somehow ascertain current drain in mA and display it over the battery bars on the icon. Nothing more. Be great if one of you clever programs could put this together. I reckon it would be popular.
Would any one else be interested in a replacement for the default status bar battery icon that worked like this?
Battery Status is ur best bet
Hi all,
One of the things that annoys me about the S200 is that the battery indicator, when charging, doesn't show the actual charge level (but instead, cycles through 20/40/60/80/100)
So, if I want to check the charge level of the phone, I have to disconnect, and then (if it is not charged enough), reconnect.
Is there any tweak that would get it to display actual charge? (All my previous WinMo phones - even going back 8 years - behaved this way)
Thanks

Check out this App. I use it and i love it. It shows a battery line and can show percentual state of battery.

Hi!
I'm trying this on Arto's 2.8 (Manila) ROM and it doesn't appear to do anything at all... are you using a Manila or non-Manila ROM?
Also, it isn't clear from the description if it will display battery level accurately while charging.. can u confirm it's behaviour?
BTW Arto's ROM already includes a mod to show battery to 1% accuracy (but while charging it only shows a charging icon - and battery settings cycles 20/40/60/80/100).
I think the issue is not in the displaying app, but some means to change how the phone reports the battery level to software (perhaps a reg mod or driver mod)
/Sifaan
forgett this app
my mistake. batti only shows % steps. this means that the line is cutted in parts (like blocks). sorry no numerical display
I downloaded Circle Battery Widget the other day to have a battery widget on my lock screen (I use WidgetLocker). Immediately after putting it on display it showed "74%" which I thought was weird. Turns out it shows the correct percentage exactly all the time.
Thought Motorola designed the battery meter to only meter in 10% increments? Every other widget/app shows only 10% but this shows exactly...might have something to do with it actually measuring the battery voltage (you can see the voltage and temp of the battery in the corresponding app). Someone else download it and check it out

There was a thread about this somewhere else... the general consensus was that it works on estimations. I monitored it as the power drained and found that the stock "10%" scale changes when the circle widget goes from 5-4 (example: goes from 60% to 50% when the circle widget changes from 55% to 54%).

Well either way it's been pretty spot on thus far. My only guess was that it showed a percentage based on the Voltage (because it shows the exact voltage in the battery in the options if you poke it). It's crazy accurate...not sure why Motorola didn't incorporate the same idea into its own Battery displays...
I'd only wonder about moto's decisions when they start making sense.

EXCELLENT!!!! Thank you for point this app!
Hi, i've the following problem: every time that i'm removing the battery from the phone when i'm restarting it the clock time is not more right.
I've to set the clock again.
Is it normal?
Have the phone a backup battery to mantein the time?
thanks
Have your HD2 get it's time from the internet. I am running a NAND Android ROM right now so I can not go through my HD2 to refresh my memory but Just go to your settings tab and keep going through your settings there and you will find option. Hint you eill have to select a sub option in one of the settings that you touch on to see the option, sorry I can not give you a step by step guide.
Hi i've already disabled the option to receive the time from internet, but i've the same problem: everey time i'm removing the battery the clock losts the right time and i've to set it again.

No don't disable it, I was telling you to enable it as it will help keep you clock set to the correct time. Sorry if I was unclear.
i've done as you described and the time difference between the real time and the hd2 clock is decresead but there is yet.
Have the phone a memory battery to mantain the clock time without the main power/battery?

No the battery is the main source of power. for the HD2 unless you have it plugged into the wall charger. And even if you have it plugged into the wall charger but the battery is out you would have to bridge to of the battery pins to make it turn on.
Now how exactly the phone keeps time if you pull the battery out is a unknown to me. But lube someone else here can fell you and I in on how this works.

I suspect there is a capacitor in line somewhere that is good for a few minutes, designed to allow one to change out the battery.
But you bring up an interesting point. Even when I power off my HD2, when I power it back on the time is correct. Of course, I have it set to get the time off the network, maybe it is doing that when it connects.

On the phone's mainboard is soldered a small tablet battery just as for handwatch but with leads, may be it is depleted. If You can handle a soldering iron, it's no problem to change it, else go to service.

Rock on brother teach me some more.
I guess it's a lithium battery or a EDLC (Electric double-layer capacitor) like in any other digital device with on-board RTC but a very small one
yep, it's a lithium - manganese dioxide cell. The problem with those found in cellphones is that they are not quite rechargeable. Normally they aren't supposed to discharge in the typical lifetime of these devices but prolonged exposure to heat is their main enemy (they can be damaged by temperatures above 50-60 degree).
I don't remember it's exact placement, but from pvii's pictures and what i remember from disassembling my hd2.. i guess it's just underneath the CPU
Careful when soldering there, you have a multi-layered pcb and the bga matrix for the cpu on the otherside.

The behaviour of my clock is very strange because when i'm removing the main battery it does not restart from the same time every time (if i'm removing the battery from a digital clock and every time it restarts at th same time es 12:00). Each time the clock has a different time but it is not right.
Could you explain me this, please?
thanks

A digital clock is a counting system. It counts pulses from a pulse generator and turn them into figures that we read as seconds, minutes, hours, days, months and years.
A simple digital clock does a hardware reset every time you replace the battery in it and starts count from default value, e.g. 12:00 or 00:00.
But a more sophisticated device as a mobile phone contains a more complicated real-time clock which is powered by two sources: an autonomous coin battery and voltage derived from main battery. Once backup battery discharged (still not 0V on it) and main battery is taken out clock may still run but with some errors in counts because clock pulse generator isn't properly powered, i.e. I take out main battery from my phone at 12:00 and put it back at 14:00. Then, if clock battery is discharged but not at 0V, my phone will show any hour between 12:00 and 14:00 but not 14:00 because of interruptions in the work of the generator. Phone's clock doesn't do a hardware reset after the main battery replacement. It will reset to default value only if backup battery is replaced i think, just as in computers.
"A real-time clock (RTC) is a computer clock (most often in the form of an integrated circuit) that keeps track of the current time. Although the term often refers to the devices in personal computers, servers and embedded systems, RTCs are present in almost any electronic device which needs to keep accurate time." ((c)Wiki http://en.wikipedia.org/wiki/Real-time_clock)
Hi, if you are right i'm realizing that my backup battery is not working or it's discharged .
My phone is 6 months old.
is it possible this case?
is it possible to see when the phone has been made?
thanks

You should ask HTC when your mainboard has been made by providing them your IMEI but I doubt they will answer... Did you bought your phone from authorized HTC dealer? It's still under warranty? Then try to change it by warranty if clock stability is so important. 6 months is too fast for lithium clock battery to discharge I think.
Edit: Date of production is printed on mainboard but you should open your phone to read it
I'm not sure if this helps, but my phone went an hour ahead everytime I restarted/removed the battery. When I went to WinMo settings>personal>phone
and disabled the time synchronization from GSM services the problem was solved.
