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
So recently my phone (unrooted unmodded N910C) battery is being extremely weird. When I try to charge my phone, it sometimes doesn't go beyond around 70-90% but if I take out the battery and put it back in, it shows 100%. It sometimes also shuts off on its own at around 40% and when I plug in a charger, it shows sometimes 0% and sometimes 40% (but if I turn it on, it still says 0%). I've tried a lot of things, including discharging completely and recharging to 100% (powered off), factory reset, clearing cache, and quick starting battery and nothing seems to work. Does anyone have similar problems and has anyone found a solution to this?
The problem is the battery ... the catode pin inside battery is not working properly. The motherboard of the phone it just reading the voltage and temperature of the battery. Your percentage shown on status bar is based on what current intensity is received from battery. So just replace the battery... esxuse my poor english

Are you sure it's the battery? I took it out and everything looks normal, including the pins. Also, battery apps said that my battery health was good or should I not trust them at all? I just don't want to buy an extra battery if the problem is not with the battery.
I meant the catode pin inside battery not outside. It's your call if you buy a battery or not. I just writed here how the proces work because i have fixed lot of motherboard i knowing about this i have explained to you. Cheers
i have the same problem too and i tested every things and now i am really tire , i dont think thats problem was the battery , can anybody help me plz?
Had similar problem yes new battery at the samsung store the assistant said many note 4 batteries selling I got the last one. Maybe we got a bad batch or its deliberate. Maybe we could do a survey how many people have had to buy a new battery
Sent from my SM-N910C using XDA-Developers mobile app
I also posted a similar problem. In my case the problem is more alarming, because it's happening in two different batteries, one of them is rather new and fresh. It seems that it started out of the blue, I did not make any major change in the phone.
I am still investigating the issue, I'll be back with more observations.
Just an update on my situation: I bought a new battery and now the battery readings seem to be fine.
I had the same problem as you OP. The problem was definitely the battery for me at least. Bought a new one just the other week and now everything is working perfectly
If the affected battery is under warranty get it replaced for free. Or if the problem does not get solved after cross checking many possibilities. Just buy a new battery. Simple. Good luck.
Hello,
I have quite an unusual problem - haven't found anyone having similar problem online.
I bought this phone used off a friend, who had this problem on stock as well, I flashed custom 5.1.1 and the problem persists (I thought that custom ROM would help).
I am really happy about this phone, it's just that one battery bug, which does bother me - bothers me to the point that I'm thinking of getting rid of this phone.
Basically, the when the battery is discharging, say it goes down to 95%, stop using my phone, switch off the screen.
Then after a couple minutes the battery goes up to say 97%. It's happening all the time until the phone is discharged.
Looks like the battery is miscalibrated and it doesn't read the % properly.
Although if it was really not calibrated properly, then the % wouldn't go up after a couple minutes, it would just discharge and things like that would probably happen at 10%-20%
Things that did not help:
- Discharging it from 100%-0%, recharging etc.
- Battery Calibration from Play Store
- New Battery - I bought a new, original battery for 100% (NFC works on it)
- Reflash
If someone has any idea on to fix that - I would really appreciate it.

It can't be fixed because it's not a problem.
Happens to me all the time. If I use my phone intensively, then leave it idle, it can charge itself up to 10% without it even being plugged in.
This happened on my old LG and it happens on the S4, and it probably happens on other phones too.
I don't think the percentage is an accurate representation of the battery level, it's more of an estimation.

Okay, I see.
Although I've had HTC HD2, S2, S3, and I've never experienced something like that. Never.
If something similar happened, there was an easy fix for it - new battery or recalibration.
Nothing worked for me just yet this time.
I am that kind of person that needs everything working 100%, that's why I am really annoyed with this problem.

As I was saying, it is not a problem per se, just an annoyance for you.
The only way to fix this would be to turn off the percentage display

Well, that's one way to fix it I guess, haven't thought about that.
Too bad it doesn't make it go away
Hey guys, recently I've been having a TON of battery drain. A while ago someone replaced my screen since the I dropped the phone and the glass broke(stupid me). My friend and I thought that maybe that guy also replaced my battery, without telling me. But what mostly happens: When my phone is on like 50% (sometimes less, sometimes more), it shuts off. When I restart it its at 1%. I added some screenshots off today where it happened again. What could be causing this? And is there anyway I can check if the battery is replaced? Also, the new glass has a few stripes under and above the screen. I don't mind in that much but does anyone know about that aswell?
Thanks in advance.
Well you could first try to reset your battery... There are several methods out there. Just google for it, one popular one involves deleting the batterystats.bin file.
There are also apps that show you the battery health. If it is poor, it is likely that the battery is just damaged or drained.
I used to buy second hand devices, to check the battery I usually read out the charge cycles (how often the battery charged from 0 to 100). However, I don't know how it works for Android these days. But searching for that key word might help you.
Hello all,
Recently, since about a week, i've been experiencing sudden random reboots. Often when starting apps (especially the Camera is a real culprit here, but also Google Photo's). When entering pin-code all seems fine again. and sometimes i can just use the camera like normal. But sometimes it keeps rebooting and the only way to stop it is to quickly turn off battery saver (seems a solution till now for a while)
Searching online didn't really help much, as i found a few people with the same issue end of march also on Oreo update, but no solution yet.
Also the battery indicator seems off. it often drains reaallly slow (85% at the end of the day) and then at a random percentage (like 60%) just turns off. When turning it back on it only has 3%. So it could be battery related.
What i tried:
- Let the phone drain completely, then recharge to 100% overnight.
- Remove all apps installed in the last few weeks + all unnecessary apps.
I don't want to do a factory reset, because our IT then has to set up the Authenticator again which is a pain for them (and i already had them do that a few weeks ago :angel: )
Any tips on how to troubleshoot some more or more people seeing this behaviour?

That sounds kind of like a battery that's failing.
What's the age of the phone? And did you primarily use Huawei's supercharge brick or other methods / chargers? (I ask the second, because charging at 4.5A can be bad for the battery on a regular basis.)
I'd load up something like Ampere and watch the charge / discharge rates. I'd expect a normal discharge rate around 150-350mA, but it depends a lot on what you're doing. (GPS and moderate graphics will keep it up in the 800mA-1A discharge range, the rear camera with just the viewfinder seems to push 1.2A current draw.)
I'll give Ampère a try. I used both chargers but the phone is just over a year old. Nothing to warrant a bad battery already.
Besides that, recent discoveries lead to believe slow charging could actually cause more heat and be worse for battery. But again: it's a bit soon for something like that I think. I'll try Ampère first. But i doubt that's the issue.
I've noticed my phone gets toasty when fast charging. If it's hooked up to any charger other than Huawei's, it tends to stay cool.
And it happened again. More then 50 percent and then it turned off and only had 3 percent
Dead battery I guess?

That's what it looks like to me.
Fortunately, the batteries aren't that expensive to find (Google popped up a bunch for <$20), and actually getting in isn't too difficult either, if you want to swap it yourself.
Just to close this topic properly:
The issue got worse, but i was on holiday. Ordered a new battery with a toolkit to replace the battery for 30 euro's.
When i got back from my holiday i notices the battery had already pushed the screen loose. So getting the screen off was easy. Swapped the battery in just 5 minutes and now everything is working great again. The screen used to have some bright spots and those are gone aswell. I guess it was a giveaway of things to come.
Thanks for the help!
