Hey guys who have experienced this problem?Battery percent stuck at 83% sometimes.

Like this,when you are using a Non-Original battery pack,you will have chance to experience this:

Picture from Shadow Nexus
This problem happened since WM2003,when it happened,you will get 83% as top percent of battery,whatever charging or discharging.
Sometimes it will return 100% after reboot.

Backup or Main battery pack???

Main Battery,I'm collecting data

Yes I've been facing battery issues but nothing ever happened like this. Have you ever try Cotulla's BattClear app? It could work.

I had the same issue and some other similar issues but recently nothing happens. I am using the CHS version too.

Yes,I know many chinese user have experienced this problem......

ohh, I don't know, because I still using original battery pack
Can you give me Original Battery Meter???

since we use the same type of battery and as I see we have the same problems with it, what lifetime do you get from it? I get less than 24h. it's the chinese model of dynapack and it is supposed to be 1800mah

Dynapack 1800mAh????
fake battery...
original DynaPack only give 1200mAh...

well it looks just like dynapack,same serial number but it's made in china. i have another 2 batteies an original dynapack made in taiwan and a chinese one that i used for a long time and still it lasts more than 4 days. the problem with the indicator is because the cheap (fake) models don't use the original board but an emulator for it. and so you only get from it a constant 181 mah drain and 26 degrees celsius

these are my reading from the battery pack

Well,now I know why so many people in China have experienced this problem...
Seems it reported a fake capacity sometimes.
But the Voltage of Battery is true.
Reality 83% power never came with 4.1-4.2 Voltage.
83%*1.21=1.0043
82%*1.21=0.9922
Code:
if((BatteryPercentage<84) && (g_bTmpBatteryVoltage>4000)){
IsBatteryPercentNeedFix=TRUE;
}
if(IsBatteryPercentNeedFix){
BatteryPercentage*=1.21;
if(BatteryPercentage>100) BatteryPercentage=100;
}
Hope this works...

Happened again...
Seems my code worked.

i have a battery that has problems only with the indicator. temp, battery drain and voltage appears to work correctly but for some reason the phone thinks it drains faster than it is. it's kinda annoying since when it reaches to 0 it doesn't shut down but in closes tha main functions including the phone and camera. after a reset it shows the correct percentage but agains it drains to 0 in a short time. battery life is normal (3-4 days). Is there a way to override the battery app to somehow fix this ?

Hmm...
Yes, sometime I feel it too.
But, i don't know why, nowadays the trouble seems away.

it would be great if somehow we could patch the original battery app to return the percentage depending on the voltage and we could set the lower and upper values in mV to represent 0% and 100% and automatically adjust the scale. i think that would fix a lot of problems including damaged batteries that still have a working voltmeter

yea me too... happened to me recently, before upgrading my old magician... after upgrading it with cotulla's ROM, still encountering the problem, but it's no big deal...

Funny i don't own a magician anymore but was looking from nostalja & i find this, anyway cut to the chase i have an extended battery on Kaiser and have had the same scenario, all beit i pop battery give 5 mins and reinsert charge and all fine.
Just funny the 83% as i run 2700 and still same %.

Self Charging

Battery was 28% last night, the phone gained 3% overnight when It usually drains 2%, no usb connection as you can see in the graphic. What could cause this behavior? I’m just curious.

Perhaps its an issue with your battery controller. It was projecting a certain loss of battery but when it did not after waking from sleep it assumed it had charged and displayed a higher %?
That is completely conjecture based in no fact other than those made up by me, so please take it with a grain of salt. =)

i'll keep saying this, but nobody wants to look at the nexus s battery driver code. seems the phone is based off voltage tables, which fluctuate under load, and hence when you charge to 100% and unplug, it drops to 97%. because the voltage drop.
same could apply to this situation, very often you can see your voltage drop like that. especially if you left the phone idle all night after using it hard prior. voltage drops then increases.

Yes, I was using maps very hardly (at least in comparison to the rest of the day) and that’s the reason of the fast drop in the graphic, then the phone went sleep for almost 7 hours. I’ll take a look at what you’re saying about voltage tables. Very interesting info here.

you were using maps right around the time of that drop? then yes that's the reason. i wasnt directing the "code review" to you lol, just more of a general thing that was discussed in the forum previously. sorry
but this would definitely show, in my opinion, why there is also the 100% to 97% drop when taking the phone off the charger. voltage drop always ocurrs here.

No reason to be sorry about, I didn’t take it that way; I just like to learn new stuff about how things work.

its the battery meter. you probably rebooted. the battery meter in android is known to be inaccurate. sometimes after a reboot it can gain or lose percentage. ive gained 25% before after rebooting! in reality, you didnt gain anything, its just the meter being off by a bit.

I just want to know how you get nearly 4 days of use out of a charge!
Don't you use your phone?

I haven’t seen this after reboot, this happened after awake and it wasn’t sudden. Phone without signal in the graphic is the “airplane-mode” It wasn’t off. I know that battery didn’t gain any charge, of course, It’s just the weird behavior of android reading battery information.

lol, yeah, It was a very quiet week.

it would be awesome if you could test this if you dont mind. turn your screen brightness to max, make sure your on 3g and not wifi, open google maps and scroll in one direction for about a minute or 2, check the battery percent and voltage. then turn off the screen, leave it sit for a few minutes, then see the percent and voltage readings.
maybe try a test a few times just for fun...you wanna place as much load on the phone as possible, so maybe even turn on the camera flash?

does any body else has an easier way, or can recommend a market app to test the battery life by using full features?

Quick test here:
Beginning with 3728 mV, stress the phone a little and It drops to 3622 mV, then I let the phone sleep for couple of minutes and after wake it battery shows 3730 mV. It seems to show higher values than those that were present before sending the phone to sleep. What could be said about that?
I’ll do another test with full charge and more stress, but for the moment, my phone is charging, yeah…. Finally.

its too bad my app (my sig) doesnt work for the nexus s, because i just recently added real time voltage vs current graphing, taking 2 second readings, for these exact circunstances. its fun doing these types of tests on my n1. but the battery driver and model is too different in the nexus s to use the app...
n1 doesnt use voltage at all for percent readings, but my hunch from code was the nexus s does. that's why i was so curious. check out some screens though for fun. you can really do some interesting tests with such high sample rates.

Mugen battery dying?

i dont think i can get a full day like most of everyone, i already delete the battery stat and its still not working

How long have you had it? New batteries should cycle afew times though before the gauge can be trusted.

I get two days out of regular use from my mugen 3600. I've had it for about 5 months now. Still runs strong.
Sent from my T-Mobile G2 using XDA App

I get 2 days of regular use and over 3 days with little usage on my 1800mAh battery, you should get LOADS more on yours, 4 days at a minimum.
Charge up to 100%, let it rest on charger for 2 more hours.
Go to recovery and wipe battery stats.
Use the device as normal but do not charge until it dies at 0%.
Charge to 100% and again let it rest a bit, then resume your normal usage.
Every once in a while or after flashing a new ROM, let it discharge to 0 to get accurate readings.
And also be aware that google GPS-based apps have problems on CM7 based ROMs and the GPS sometimes stays awake or some such bug. It doesn't show on battery usage graph but every time you use google maps, google goggles or similar I recommend rebooting because there's a chance it's slowly draining your battery in the background.

Just a thought: Do you really use google maps so much that it can account for 22% of energy consumption on a 3.6k mah battery? That seems kind of excessive to me.
I mention this since I used to have problems with google maps starting on its own in the background and it really drained the battery like crazy. (oddly enough it would only start whenever i opened the stock mail client.)

The latest google maps does not run in the back ground even after exiting like previous versions of maps (you would have to either reboot the phone or use a 3rd party app to manually kill everything related to maps).
So my recommendation is to do what the above said with the calibration and then make sure you are on the latest maps.

A lot of people give the advice to drain the battery until it dies. Very poor advice, and you can kill the battery that way. Just drain to 20% or so. No need to go any lower, its not going to make the battery meter any more accurate.

I do actually and I get probably 10 hours extremely heavy usage! Light usage to no usage I get 24 hours plus on 1900 mah chichitech. I've gone 4 hours before my phone ticked from 100 percent to 99 lol.

[Q] Please Help!!! Battery shoots up automatically.

I usually flash custom roms on my device. But my device has one unusual behaviour. When I charge my device and suppose it is 70 percent charged and I reboot my device within 20-25 minutes, the battery level shows fully charged. (100 percent) After that the battery drains within 2-3 hours. Because of this I charge my device 3-4 times everyday. This happens on every custom rom I install on my device. Should I change my battery or is it the device's fault? Please help.

the percentage increase after reboot is a htc common issue while charging
about the fast drain maybe your battery is dying or doesn't makes contact properly
check it

Thanks for providing this useful information. Do you mean using paper or something that holds the battery tight or I misunderstood something.

exactly that
use something to hold the battery and see if you still have reboots

Actually I think the paper solution won't work. He's not having reboots, just the battery is draining fast. It looks like that your battery is almost died. I think you should buy a new one. And I highly recommend Anker's one.

Thanks once again. Will try.

I didnt want to make a new topic but I have similar problem:
i switched from standart ROM to Cyanogenmod 10 nightly builds for my Sensation Pyramid (original battery, about year old).
Everything worked fine, but there is one more than annoying problem:
I charge phone to 100%, i pull charger out. If i use standard things on phone (settings, gallery etc) everything seems to work fine. As soon as I enter any applications (Twitter, Facebook, default Web Browser) it just shuts down in 20seconds or in 2/3 minutes (always some random time, i can browse web 10 seconds, it shuts down, sometimes i can do the same for a minute and then it shuts down), it doesnt reboot just shuts down.
When I turn it back on, it shows battery level ~ 9-15%. It was 100% just 3minutes ago. I charged it for hours before, so that 100% should be real. I tested with battery drain monitoring app, when i use any apps, battery drops for like 1200% every minute. Its Ok on standby mode.
When i just reboot the phone, it comes up with some random battery percentage, f.e 47%. So it can go from 100% to 7% and after reboot it goes to 47%.
I thought it might be a ROM problem, so I installed this albinoman887 ROM http://forum.xda-developers.com/showthread.php?t=2115520
Did factory reset, cleared cache, phone was 100% charged. But the same problem.
I dont thin its battery problem, because it was OK with stock ROM. Is there anything i can try to fix this problem without going back to stock ROM (or other Sense based ROM)?

Really no advice on this?
Im not so good with Kernels etc., but my guess is- maybe this has something to do with CPU usage? I checked with CPU Spy app, it says Internet explorer, other apps use 1566MHz. Isn't that too much?

OPO battery drops dramatically after the last OTA

After installing CM13.1-ZNH2KAS254 the battery lasts only four to five hours by merely using the phone.

- How many full cycles have you had since updating?
- Are you using the original OPO charger and USB?, aftermarket products don't offer the same charge rates so may affect battery use.
- You have a device that is 2 years old, the battery regardless of it's total charging cycles is already past its 12 month expected lifespan.
- Try clearing the cache via recovery, this is something always recommended after an update, regardless of how small as it irons out any duplicates or issues.

I bought the phone this year, I am using the original charger and cable, but I have been charging it whenever I had the chance because of my work. For example from 35% to 80%, never letting the battery drain out completely. I contacted OnePlus and they advised me to let it shut down and full charge the phone three times. I will post the resaults.

I also use tethering a lot, at home on my desktop pc. I see that while tethering is on, the phone is charging really slow, like 1-2% every 10 minutes. Could this be linked to the battery lifespan?

Battery issue and screen overlay issue after update 13.1
After update my OPO yesterday to CM 13.1 ZNH2KAS254, two major issues I m facing ans furst is battery charging is very slow in simple words its not charging and second is screen overly issue due to my applications not behaving properly. Please help as it was working fine before update

This is a known issue of slow charging with the latest official update. If you are rooted the device, you can switch to Custom ROM like sultanxda's which does not suffer from slow charging.
Battery life actually depends on how you use the device. If you just use the device to read, it'll last longer. If you use the device only on WiFi, it'll last longer. If you have good network coverage, it will last little longer and most important is the age of the device.
Battery drain can be because of some of the apps using the device resources(like Google Play Services etc) continuously and not allowing the device to go into deep sleep mode.
Tethering drains a lot of battery as your device acts as a router and gets the power from the battery

This is a common issue on MM roms and the OPO.
Lots of people are reporting wacko battery behavior after upgrading to MM.
In my experiments, the CM 13.1 by Sultanxda was the least offending, and possibly COS, but I don't exactly remember about COS.
Switching back to LP will correct any battery issues.

What about screen overlay which is very frustrating.

It's been almost 1.5 years since I'm using my OPO.
With the latest COS update, battery backup hasn't changed anything toward bad if not better.
6-6.5 hours SOT always based on my usage. While I get under 5.5 hours SOT with similar tweaks using SultanXDA CM e.g.
COS 13.1 is running really good for me, battery is great, and honestly, since COS 13 came out, I've literally stopped using custom ROMs while on COS 12/12.1 I was barely using the official ROM. Mostly was on Resurrection Remix.
So battery backup wise, COS is "GREAT" if you know what to tweak, and yes the phone charges from 1%-100% in 1.5 hours using the stock charger.
Do a battery calibration, complete calibration, here's what I do after every flash, drain to sub 1% when phone turns off, go to recovery and keep it there until it "completely drains itself to death", then start charging from complete zero all the way up to 100%. That works for me, can't take any guaranty for your device though.

[SOLVED]
I did what they suggested and the battery lasted a full day, 08:00 to 02:00.
