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.

I am having problems with the internal battery in my wizard. Everytime I switch battery my clock and calender resets. I have the service manual and see where the back-up battery is. I was just wondering what kind of battery it is and if I can just replace it?

The Wizard does not have a backup battery like other PDA's. It has a persistant memory model like a PC. I have never had to remove the battery so I guess the clock would reset.
Whether the Wizard has a battery or not there is definitely a design flaw. It always used to remember the time and date settings when removing the main battery buy after about 6 months it no longer does. this has happen on both our Wizards and many others. It's very annoying when you change sims and then have to reset the time and date.
So far nobody has been able to explain why this is happening. There are thoughts that it may be the new roms which have changed something in the power management.
Kiru, you say you have the service manual and have found / identified the backup battery? That would very interesting if there is one.
I remove my battery to move my sim to other phones quite regularly, and my clock/date settings always remain intact on my mini-s. If I look at battery stats on my SPB pocket plus, it shows 2 batterys. Main batt and backup batt. I always assumed the device had a backup battery to store date/time settings.....

He's talking about the small backup battery inside the device. If your sure Wizard has a backup battey, then yes its removable.
The type of battery, and volt is labeled on either side of the battery.
Just my $.02...
If this problem is less than a year old try warranty repair options?
Also, you can set the phone to update its time and date from the cell tower. I've never set the clock on my device it just nabs that information from the cell tower. Should happen as soon as you get a signal instantly...
The setting for it is under Phone -> Time Zones
Hope those help...
As i'm sure the backup battery is only used for the RTC (Real Time Clock) since the device is now persistent storage...

Just follow what FESCSteve said...and it should work....if not....then send me a pm and I can email it out to you
When i switched my mainboard my back up battery was dead, but after a couple days its back to normal, so i guess just keep charging your device and the back up battery will work again.
as for replacing it, it's soldered on so you'll have to unsolder it to replace it.
At page 37 of the service manual you can see about a "Golden Cap". It is not a battery, it is an high capacity capacitor. It works like a battery but has never to be replaced because it (should be) is charged by internal circuitry from main battery.

okay I managed to get my internal battery working once again!!!.....I think is drained due to the fact that I don't charge my batteries with my phone, but use a desktop charger. I then plugged my phone into the charger for about 24 hours, and finally, the back battery is charging (as to what pocket breeze says) It still isn't 100% charged, but it seems to be holding the time and date again!!!... just fyi I have 3 batteries for my wizard and never charge them using the phone....so that could have been my problem.
same problem here

Last week my battery was totally empty so I had to charge it using my 220V charger.. At that time I also found out that my internal battery is empty when I exchange SIM cards. Last Sunday I charged my SPV M3000 for like15-20 hours but I still have the same problem...
What more can I do to make it work again?
I have same problem with my O2 Mini S. I charged it with the wall charger for around 18 hours although it took just 2 hours to get the the main battery fully charged. The date/time still reset when I plugged it out and removed the main battery.
Anybody kindly help please. Thanks so much in advance.
too bad my problem came back again....and I don't know why.....when I left my phone charging almost all day, my battery meter says my backup battery is 75% full.....then when i changed my battery.....all my clocks reset again...it's gets really annyoing especially if you change batteries alot. But does this only happen when people are using spare batteries?..and always swapping back and fourth?, I rarely use the phone to charge my battery as i have a desktop charger.

It seems that there really is a backup battery (capacitor) that can be damaged. I have read the Wizard service manual and this little component has to be replaced if this problem still occurs :-(....
both mine and my wife's wizards are only charged by the mains charger and they both loose the time and date settings when changing sims. This problem started about 6 months after having the phones so I think some component seems to fail after a while as there are many reports of this happening.
All I can say is that it's very annoying as I travel frequently and change sims often.
As for getting the time from the cell tower, this doesn't work for me for some reason.

Unfortunatly I have the same problem. When changing the sim and thus removing the battery I lose the time and date setting. I charge my phone by the mains charger or sometimes by an USB port.
Perhaps it has to do with the new ROM I use? I recently upgraded to the molski rom. Perfect ROM by the way.

I don't think it's the ROMs. I still use the original WWE I-Mate rom (2.16, the one and only update they did so far). It's possible that the ROM introduced the problem but then everyone using the ROM would have the problem which is not the case I believe.
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
I have charged my Nexus One yesterday for the first time. I live in holland so i had to use my USB cable, and the power adapter that came with my HTC hero to plug my USB cable in.
After the phone was charged 100%, i disconnected it from the charger and only downloaded + added a widget to my home screen. After i did that the battery was already down tot 97% :O:O
Is it defective ?
i noticed having to complete a few charge cycles.. charge fully, use it till dead, charge again
now it seems to hold out much longer
Hmm ok i'll try that. But did yours also drain this fast?
what setting is your screen on? seriously though, im sure some other battery experts here would know, but i think they take a few cycles to get to maximum efficiency

I've noticed this too. However as soon as the battery reaches around 50% it takes a lot more to drain so it evens out in the end I guess

Hmm ok so it also went that fast on your phone? i have been using it for about an hour now and its down to about ~90% =\, concerns me a bit.
Found out something else, concering the usage of the screen. When i look here:
Menu -> Settings -> About Phone -> Battery Use
The phone tells what uses the battery the most or something, but the strange thing is that it says:
Display 55%
Isn't that very high? Maybe that is causing my battery to drain so fast
Battery meters are not an exact science. Its using what it knows about the battery's state to guess of how much % is remaining. The battery meter will need to be calibrated once, and then overall battery should improve with your next normal 3-6 full charges.
Again, you do not need to and you shouldn't repeatedly drain the battery to 0, only once is this needed to set the phones battery meter, unless you clear it (possible within amon ra's bootloader).
As for your observation, yes that is completely normal, there is not a whole lot of definition within 3% of battery as far as displaying it. What the real picture? Enter in #*#*4363*#*# on your dial pad and then go to battery information, and you'll see the accurate voltage. (this is also accessible from "spare parts" if you have it)

All %'s here are vs the amount of time on battery (shown at the top in h:m). If you just unplugged your phone and you go looking here, you'll see the display % VERY HIGH... because the screen has been on the entire time its been unplugged
Its a % after all of the usage since last unplugged.
i've noticed my battery life is much better since i got the desktop dock.. lots of people charge until the light turns green then immediately grab it and start using..
leave it for another hour or two and it seems to get much better.
dont know if anyone else has noticed this but the top corner indicator light turns green once the battery goes somewhere over 90%, leaving it charge longer will get you to 100

You probably found this by now, but one flick to the left and you should have a widget for WiFi, GPS, etc. The far right one toggles 3 levels of screen brightness. The brightest two settings really suck down battery.
just a tip, when you are draining it to recalibrate the battery, after you get to the point that the phone shuts off, boot into the bootloader and run that thing till it completely dies... i did this for my phone, sat it in bootloader with a bright ass screen for like 15 min before it finally finished off... get every last ounce of juice out of it before you start charging it back up
Hmm thanks for al the reactions guys. I'm going to recalibrate my battery now, and lets see if that helps a bit .
Then i have a other question, its not about my battery but since i already have a open topic i dont want to create another one .
Can anyone of you test the following:
When you are calling with someone, and your calling volume is on the maximum (so the volume of the speaker that you hold against your ear). Can anyone notice a little crack from the speaker when the other person talks a bit loud or make's a loud noise? I'm wondering if there is something wrong with mine. With several tones the ear speaker cracks a little bit, like the sound is to loud or something?

Hmm ok so it also went that fast on your phone? i have been using it for about an hour now and its down to about ~90% =\, concerns me a bit.

Yep sounds about the same on my phone, dont worry about it lol
The draining thing is from the old nickel days, the lithium batteries are made for daily use so just treat the phone as you would normally. The battery will get better as time goes by.
Also I am not having that problem with the speaker
Hmm, I have my device since last week (Netherlands) and the battery usage is frightening. Sucking it dry in about 24 hours. I haven't let it die out completely though: I thought lithium batteries were not supposed to be used that way. Ni-Cad batteries were used that way.
Ah, see here:
Guidelines for prolonging lithium-ion battery life
Lithium-ion batteries should never be depleted below their minimum voltage (2.4 to 2.8 V/cell, depending on chemistry). If a lithium-ion battery is stored with too low a charge, there is a risk that the charge will drop below the low-voltage threshold, resulting in an unrecoverable dead battery.[citation needed] Usually this does not instantly damage the battery itself but a charger or device which uses that battery will refuse to charge a dead battery. The battery appears to be dead or not existent because the protection circuit disables further discharging and there is zero voltage on the battery terminals.
Lithium-ion batteries should be kept cool. Ideally they are stored in a refrigerator.[citation needed]
Aging will take its toll much faster at high temperatures.[citation needed]
[edit] Prolonging life in multiple cells through cell balancing
Analog front ends that balance cells and eliminate mismatches of cells in series or parallel significantly improve battery efficiency and increase the overall pack capacity. As the number of cells and load currents increase, the potential for mismatch also increases. There are two kinds of mismatch in the pack: state-of-charge (SOC) and capacity/energy (C/E) mismatch. Though the SOC mismatch is more common, each problem limits the pack capacity (mA·h) to the capacity of the weakest cell.

So, if you want to brick your battery, by all means, suck out all the power.
i have a mytouch but i think the things i do can be used with all androids....first recalibrating is a good way to get a fresh battery...then the brightness also helps along with any wireless things u dont use like wifi gps etc.. they should be turned off an brightness should be low...i have downloaded a app lately called automatic task killer..i think this is better than any other task manager because other task managers dont kill apps wen phone is on standby ..apps r still running wen screen is off an automatic task killer kills them..i think u should download this and also have a task manager to kill apps wen u use the phone..another thing is charging the phone wen its completely off..wait until the the light turns green then leave it on for another hour or two then turn it back on....i have seen an increase in bettery life by doing all this...any one esle have any tips ..let me kno
I´ve just come back from a two month expedition on Borneo. But when i got back to civilization and turned on my trusty N1 I quickly realized that my battery performance has dropped significantly. Before I usually had one day of heavy use (including Wifi, 3G, tethering and GPS usage), but now I only have about 7 hours standby with everything except GSM turned off. Which renders the phone useless for my (normal) use. The phone actually consumes so much power that the battery level drops while charging. The only way to charge it up is to turn the phone completely off.
I flashed the RoDrIgUeZsTyLe™ MIUIMOD -ROM before I left for my trip, so I thought maybe that was the problem (some bug i the kernel or something), so i flashed back to CM6 with no success. I have also tried a new battery.
Anyone knows what can be the cause?
All help is deeply appreciated --- I miss my good old N1!
I accidentally placed this in the wrong section - can anybody move it to Q&A?
Try the battery app in my sig to pull your battery values, then post in that thread and one of us can help you see what's happening with your battery.
maybe the charger is the problem?
Just throwing it out there... I've seen it happen for Laptop users...

Hi,
I had similar problems with my rooted N1 with stock Froyo.
The problem for me was a radio image older than regular. Baseband version should be something _4.06 or higher.
You can check this information in Settings ->About Phone

I got 32.41.00.32U_5.08.00.04 so it doesn't seem to be old, but I'll try to update the radio anyway with a custom stock rom from modaco. Will let you guys know if it helps
Update: I'm now back at *****_4.06****. No change
My first thought is: what level of power did you leave your battery with before you went away?
Lithium batteries are permanently damaged if the voltage drops below a certain level. Leakage will mean that any battery left for a while will lose charge.
Therefore, if you leave a battery with close to zero power left for a long time, leakage can mean the charge level drops below the critical minimum level and the cells become damaged.
As such, it is recommended to never store lithium batteries with below 40% charge, and to store them in a cool environment, since leakage is faster at higher temperatures.
Yeah, that was my first thought too, since I forgot to turn it off before I left (the phone was stored in a room with AC at least). However, I have now gotten a new battery and it doesn't help...
I have tried to check if there are any programs that are running in the background that draw unnecessary power, but i cant find any ---at least not with system panel. The cpu-load also seem to be normal.
Anyone got some ideas?
Thats really wierd... The only thing you can do is reflash the radio and flash it to stock. Then use the new battery and charge it overnight - so it overcharges slightly. Let it totally drain till the phone turns off, and repeat a coupla of times. Ignore the levels reported by the phone.
See if it starts to behave normally after that. If not you either have another dud battery or there's something wrong with the charging circuit in your phone.
If you have a friend with an N1, you could try charging your respective batteries in your phones, then swap batteries. See how much time each phone lasts
Thanks for the tip.
I'll try that before I buy a new cellphone.
Hi guys,
My had brother hard a problem with his phone regarding his battery life. He claimed it drained too quick. So he bought a new phone.
After I had "accidendatlly" destroyed the eMMC of my nexus 4 (See this thread) he gave me the phone and told me if I could fix it that I can buy it for a sharp price form him.
I've replaced the battery with a newly bought one online and got the phone out of hibernation mode by connecting it with USB cable and doing the volume down + power button trick.
I've noticed some issues regarding the battery:
- The first time I rebooted it battery life went from 96% to 84%. This was when doing a factory reset (from the menu in android 4.2.2). This has occured once.
- Last night the phone was fully charged so I hooked it off the charger and turned it off. This morning I turn it on and I notice the battery is at 66%. Literally 1/3 of the battery life was lost when the phone was turned off.
Obviously, (I think) there's a loss inside the hardware of some kind. There's one piece of history attached to the phone.
My brother had it one month and dropped it on the floor and his screen was cracked. He then let the screen be replaced by a repair center. They did replace the screen and locked the screws from the battery with some kind of glue (i think) because it was very hard to loosen them.
My questions:
- What could have caused this? Can it be by something done by the repair shop (reversible?)
- In which part of the hardware is this (loss) most likely to occur? Or one can't know this?
- Would it be sensefull to disassemble the phone and replace the screen with the screen from my broken phone (the one with the broken eMMC chip), or is there 0% chance on success by doing this swap?
- Any suggetions on how to tackle this problem or is it just something I'll need to accept. (which is hard to accept, )
Kind regards,
Semi
You should first try to charge it to 100%, then calibrate the battery (there's a little tool in the play store called BatteryCalibration). The percentage values are just approximate. Android knows the amount of mA the battery has when full and constantly checks the current as it drains to calculate the percentage left.
Calibrating the battery basically means deleting these statistic files to allow the system to start from scratch. You may need to do a few discharge/charge cycles until it is somewhat reliable.
If this doesn't help I assume the fault is hardware sided.

Hi thanks for your Swift reply. ive checked the app out and i think it needs root. This phone hasnt been rooted yet so ill Get to it when i get home. Greetings.
I do have the exact same problem (phone was never droped) - see this thread:
http://forum.xda-developers.com/nex...rs-off-charging-battery-t2701353#post57181337
Nexus 4 seems quite vunerable to this though I've not found the cause/solution for this on the web yet.
Exactly the same here: Old battery made a worn-out impression, so bought a new one. Actually tried three different new ones from ebay now, all do the same: They charge up to 4.3V around, and when unplugged drain to 87% in a few minutes, i noticed the voltage going down to 4.0/.1V mostly, too.
The current battery seems ok from battery life, but i want an even distribution of the battery status, no matter the voltages - how can i achieve/fix this?
