Battery level indicator - dies at 50%

Is it just me, or is there something wrong with the battery level indicator with Wm6?
At first i thought it was my battery, but now i bought a brand new one, and it still dies at around 50%.
The actual battery length is correct, so it's not that critical, but it's nice to have the low battery warnings at 15% 10% etc...
Is there a solution (or work being done) to this? IF not, post your experience here, so we can try find out who it's affecting and why. (I know i'm not the only one with this problem)
Using that pro business v3 and radio 1.17.

I use a create WM6 ROMS and don't have any issues with my battery (it goes down to 1%)
So I would like to suggest a few things...
1). ALWAYS fully charge your battery before any ROM update.
2). NEVER buy a non OEM battery (cheap knock-offs)
3). UPDATE your bootloader to the latest version.
If you have followed the above steps and still have issues, then I would suspect you have some type of hardware issue. To check this flash the OEM ROM back to the device and see if the problem still exists.
Let me know how it goes for you...
Take care,

[Q] weird battery issue

hello ppl,
I have this issue with my battery:
This afternoon my battery indicated 82%. the phone shut down and after a reboot it indicated around 27% battery left.
Later in the afternoon, after a reboot, I charged it for like 2 mins. it indicated 12%
I unplugged it and rebooted into recovery (4EXT) and it indicated 60% battery lvl.
I rebooted the ROM again and this indicated 34%
this event (reading 3 different battery lvls) took place in 1 minute, and the phone was not charger connected. It went from 12, to 60 and to 34%.
This really looks like a battery stats issue but what I can't help to wonder about is the following; do recovery and the ROM use different battery stats? this particular story sure gives that impression.
I plan to wipe battery stats after a full USB charge. U guys got any pointers I could consider? I have a stock batter for about 2 years now.
ROM: CM10.1 by Albinoman
Kernel: 3.0.67 ChronicBruce Linaro
Governor: ondemand
clockspeed: MIN 384 MAX 1728
I/O schedular: SIO
note: I did not experience any battery issue with this setup for at least 4 months prior to this problem, while using this setup.
attached a SS of the battery levels after reboot and shutdowns.

Seems like you're experiencing the same issues. The battery percentage was also way higher in recovery mode than Android showed me. Never noticed that before, so I'm not sure if that's normal, or both our phones / batteries are malfunctioning.

Wiping battery stats does nothing. 2 years is quite long for a battery, get an Anker?

Before buying a new battery, did you attempt to flash a new ROM? becuase you seem to run a (very) old version of CM10.1 (I believe since March?), and although it's weird this popped up after four months, it is possible to be a problem in the ROM, especially with all the bugs fixed along the way. I believe updating the ROM should be the thing to do, before trying to change hardware parts (even battery), and if it won't work, you can always buy a battery (don't ofrget to back up your current ROM first).

I'm a mediocre XDA visitor and phone tweaker, so I didn't realize ROM's would get obsolete that quick (in my opinion). I will try to flash a updated CM, see if that works.

ok I updated my ROM. But there's no change in my batterie's behavior: shutdowns at high battery lvls and drops from enar full to near empty after the reboot.
I'm plannign to buy an Anker. but if anyone has some pointers that would be mint.
I already did the paper between battery trick.

Another update, today i noticed that the battery is a little bit swollen. The battery casing doesn't close properly anymore. When looking closely i notice the battery being slightly thicker. I don't trust it and don't use it anymore untill i got the anker

[Q] Is it battery or ROM or Kernel issue ?

Hi,
My phone is almost not charging full or it doesn't show as such.
This is detailed breakup of my issue :
I put phone at charging exactly at 2pm at 2%
3pm it was at 36%
4pm it was 54%
5pm it was at 64%
6pm it was at 73%
7pm it was at 82%
7:30pm it was at 84%
after this I removed phone from charging and rebooted it. Surprisingly it showed 100%.
Battery doesn't last more than 12hrs no matter what I do. I am using Greenify too.
BT, GPS, Auto-Sync, 3G, etc all are off. WiFi On 24hrs.
Screen-off battery drain is also around 8-9% per hour.
Can I do/try something on software side before I order a new battery ?
Right now I am on Carbon ROM (20131008) with stock kernel, 1512, Ondemand, SIO, No OC. Its same on every ROM I tried except seemingly on ARHD 7.3 (used it less than 24hrs. Its rock solid and smooth.)
I would greatly appreciate any help/advice !

I also has this issue still looking for the solution
Sent from my HTC Sensation using XDA Premium 4 mobile app

the battery misreading while charging is a common htc's fault after rooting and there is no solution yet
i have the same thing while charging my device
but the difference is i don't have that fast drain
how old is your battery?
did you try a different battery?
make sure it fits correctly to the pins

Battery is just 1yr old. Yup I checked the pins. They are correctly fit.

this is a rom issue i think as this has also happened to many people and and this happens after many days on a single rom (and u make the rom unstable)
the solution is simple just backup ur data and full wipe and flash rom again and u will be good to do for next many days (if u keep the rom stable)

I flash ROM almost every alternative day and I always do Full-Wipe

Battery Kernel issue
I am new to xda. I actually flashed a new rom after that phone doesn't charge after switching off. Could it be a kernel issue or the rom's issue. I have a Canvas HD. And sorry if this is not the place to ask the question. I couldn't find any other thread related to this. Please help.

Similar issue here. My charging often stops at about 80%, but after a reboot the battery's full charged.
My battery also gets drained very fast, but it's about 2,5 years old so that's probably the problem.
With the CPU clock speed @1,5GHz and the GPU @266MHz i get about 15h +/-2h of battery life.
I keep battery saving ON most of the time. Bluetooth, GPS, 3G etc all OFF. WiFi ON for about 1-2h per day (if i would keep it on longer, my phone would be dead in 4-5h).
I'm using ViperS 5.2.1 right now (full wiped before install). I got the same experience on ARHD and previous ViperS versions.
Tested the charger - it's fine.
I was wondering if anybody else got an old battery like mine and how long does it last on full charge

Hi guys,
I have a HTC Sensation XE that i bought three days ago (second hand) and i have the same problem with the battery % not reading correctly.
Now this is what i observed:
- the charging is very slow - from 20% to 40% in 2-3 hours
- after 2-3 hours of charging if i reboot the phone the charging LED turns green and the battery reading says 100%.
(i tested to see if actually it got charged to 100% and it did, i turned everything on, watched a HD movie, played some games and after 5-6 hours of playing with it i still had 50%)
- tested the battery to see how fast it drains from 10% to shut down and it went on at full brightness and everything on for about an hour and something so this means there might not be any problems with the battery
- so the reading is wrong because the battery is charged after a few hours.
- i did a test to see if the same thing happens when the phone is off and i left it to charge for 2-3 hours and when i got back the charging LED was still orange. When i started the phone the LED went off and back on as green. The battery was 100% charged.
- If the same behavior happens in off mode it means it's not a ROM problem (by the way from what i know the phone is stock, the guy never did the rooting.....that's what he told me - can't know for sure).
- from my electronics background it seems the phone updates the battery information sometime at boottime. When charging, the software keeps the charging LED on because it's supposed to charge due to incorrect data but the hardware charging controller drops the charge current because the the battery is full. So this can be an incorrect sensor reading by the software or an incorrect feedback given by the hardware controller.
So what do you think, what can cause this.
Should i try rooting the device?
And i tried factory reset from android and factory reset from bootloader and the problem is still there.

Ok so i did the following:
- unlock the bootloader
- flashed CWM
- installed superuser
- wipe battery stats
- wipe device
- calibrate battery with an application from market
The problem is still there.
I figured that when in bootloader first thing you can read is the S-ON/S-OFF. Before doing the unlock it was "LOCKED" and after "UNLOCKED".
I did a relock and the status changed to "RELOCKED" so this means the guy that had the phone before me didn't root which again means the theory that says this problem occurs when the user tries to root the device is not true because it seems the behavior is observed on an unrooted device.
I will dig deeper maybe i find more ideas on what i can do.
I'm running out of software options so this is pointing at something hardware.
I'll get back with updates when i find something else.

probably it is htc's bug
the same happened to me after rooting the device

For now I will try to make some full cycles of the battery and see if anything changes. I usually use the phone at work and by the time I get home it's almost empty. Plug to charger and till morning it's full with a green light. I will have to monitor the charging times and get back with results.
Sent from my HTC Sensation XE with Beats Audio Z715e using XDA Free mobile app

Well i did some full charging cycles and nothing changed, still the same long charge time(read by the phone) and with restart it bounces to 100%.
I had the original Android 4.0.3 with Htc Sense 3.6 at the time. Got 4EXT recovery and an 4.0.4 rom with Htc Sense 4.1. Did a full wipe and battery stats , installed the new 4.0.4 rom but the problem persists.
At this point i think the battery is the problem so the next thing to do is to change it. I will get back after i change it, hopefully sometime in november.

After a long time I managed to change the battery and after a few tests it seems the problem is still there. The time on battery improved as I expected but everything else is the same which means it's something hardware defective in the phone. Also did some tests with android 5.1 and the same results. Meantime I sold the phone and got a Samsung Galaxy S3 Neo. Hope this research gives some answers to someone at some point. Cheers.

Full charge at 96 percent?

Hello community,
So, I've got myself a Nexus 5.
Problem (?):
When I'm charging my N5 and the battery indicator reaches 96%, the charging led goes green, indicating that it's fully charged. It doesn't STOP to charge at 96% like to prevent overcharging, it just shows green led at 96% and continues to charge to 100%. It thought the problem may be the stock kernel that comes with Cataclysm ROM, so I've flashed ElementalX kernel (Without wiping anything, do I have to wipe?) and the problem's still there.
Is that behavior normal?
Here are details about my phone:
Cataclysm ROM, 5.1.1 (Jun 20, 2015, stable build)
ElementalX Kernel, latest version for 5.1.1 (4.04)
I got my N5 one or two months ago, I rooted immediately but I believe it had this issue right out of the box. And I'm using the stock wall charger & usb cable which I received with my N5.
Thanks to anyone trying to help me.
Regards

I remember a Marques Brownlee Youtube video where he was talking about Li-On battery overcharging - they don't apparently, since there is circuitry in the battery to regulate the charging. From memory, he described it as a sort of "bounce" effect, where the charging gets close to 100%, cuts out, then says "Maybe a bit more" and starts again - and it may do that a number of times. So I reckon that this behaviour is what you're seeing, and you don't have any problem.

Thank your for your reply
Now I know that everything's behaving normal. I almost thought that I have to replace the battery - and it's non removeable, so that would be a hard nut for me to crack, even with the right tools.
Last question, if I would replace my current N5 battery with another (original) battery, would the 'problem' vanish? Now I know, everything's OK.. but I'm a sorta perfectionist when it comes to devices. In other words, is that behavior related to the battery?

Here's the Marques Brownlee video I mentioned: https://www.youtube.com/watch?v=hrcbcm11830
So the answer to your question is: no, a new battery will (most likely) make no difference at all - a lot of trouble, risk and expense for nothing. I leave my phone on a charging pad every night, on a timer switching off around 03:00, and it's usually around 95-97% in the morning. Like you, I'd much prefer 100%, but I've learned to live with it, especially as my Nexus 6 very rarely drops below 50% during the day - I'm a light user.
And a word of warning to anyone reading this. We tend to go looking for solutions to problems we've already suffered, when it can be too late. I managed a few months ago to drain my Nexus 5 battery down to zero, and when I recharged it the radio was stone dead - no SIM recognised, no data service (but wifi ok), no phone calls, no texts. There are many people reporting the same thing, so beware:
DON'T LET YOUR NEXUS 5 BATTERY DRAIN TO ZERO!!!

There is no need for you to replace your battery - the percentage issue might be solved with a simple battery calibration.
But just to answer your question, the hardest part when replacing the battery is getting the old one out since it's glued in pretty hard.

disccharge from 100% until your phone shuts down, then charge it to 100% while it is off

As far as I know, this issue is software side, not hardware. Have you ever encountered this problem before ? On my ROM (which is SAOSP), the LED started turning green at 95%. This could also mean that the green LED is set to appear at 95% - 96% charge.

Yes, I've thought about that too. The LED could be the problem. Is there some sort of workaround for this?
And no, I'm encountering this for the first time. I've rooted and flashed Cataclysm ROM right after I unpacked my N5, so I don't know if the problem was on stock too.

Unbenannt, I would say that you need to stop looking at this as a problem - it doesn't seem to be one. You'll spend a lot of time and energy on this (you already have...) and the concensus seems to be that it's not worth the trouble. If you run down your battery you risk bricking the radio (and I know that GtrCraft is saying only until the phone shuts down, not drained to zero) but really, why take the risk of damaging a beautiful device for such a minor reason?

did you said charging LED ? wooh I've been using this device for 2-3 months and never seen LED blink when full charged !!
you are using any app or something for that ? bcz i'm on stock and i can't see any option to turn it on and No charging light for me at all !
does all people see it on stock ?!

I'm running a custom ROM (Cataclysm), so that's probably why.

G2 Battery discharge while off !

So, my beautiful white LG G2 is on the amazing Dorimanx Kernel (version doesn't matter-i've gone through all since V.2 until now V9-it doesn't change anything about my problem) + Cloudy G2 3.3.
As the title says, the battery discharges alone about 30-40% per night while the phone is OFF (just to be clear: not sleep, not standby, but OFF, the state from which I can turn it on only by holding the ON\OFF button for 2-3 sec). While awake (screen on or off ) the battery is normal (not better or worse than my XSP,XZ1c, Flex 2, or s6edge+). It's been like that since i bought it over a year ago.So yes, it did the same on Stock Kitkat 4.4..It came with total EMPTY battery in the box (had to connect to wall charger 2-3 Min just so it could show me battery 0-1% charging).
NOW, I know what you are all thinking: ''faulty battery'', ''change the battery,man!'' -that's what I thought too (although that still wouldn't explain the NORMAL ScreenOnTime I am geting). Nevertheless, 2 Weeks ago I ordered a new battery from here: http://www.ebay.de/itm/PRODUKTION-0...761107?hash=item1a052995d3:g:9lsAAOSwgQ9V328T and CHANGED it myself (I even received a newer one than in the picture: September 2015)..SOO ?? Well, after calibrating the new battery (the first day or so it shows strange values), I can say: the ScreenOnTime is even better than with the old Battery...But the ''turned-off time'' still sucks.. I made a screenshot so you can see what I always see after a few ''turned-off'' hours..
I never heard or read about something like that anywhere, so it's not likely that I'll get a solution anytime soon , but I still wanted to hear your opinions and suggestions..
Thank you guys! (and girls..who knows?)

I think it's a circuit shortcut on phones board that do this. But to be really sure i would flash a kdz and do all that root stuff again.
And you surely have no battery calibration in any boot script when turning phone on from off state?

Dorimanx has also confirmed (I asked in his thread also) that it's a short circuit.. It doesn't matter what stock \Rom\Kernel ..it's always been like this..
