Hello!
It's easy to check what causes to drain your battery. Just use Battery status and level and we can see it. However I want to know what the phone signal variable means. As example at night I've got a long green part even I don't use my phone. Does It mean I've got a bad reception and that's a reason for battery drain or is there something else? And is there a solution to 'fix' this?

Hello,
I want to know if my experience is common or not. I had my phone at ~90% and changed it to airplane mode to try and conserve battery while I went snowboarding. Got back to the phone about 7 hours later and it was dead. Plugged it in and turned it on and found out that "NFC Service" took up 80% of my battery for those 5 hours. When I turn NFC off this does not show in the battery log, but I don't want a major potential feature of this phone to be unusable. Anyone else experience NFC destroying their battery?
Thanks.
I am noticing my Galaxy Nexus not lasting as much as my Rezound did, but it had a larger extended battery. I also use Ultimate Juice to enable / disable my internet connection. So with my extended battery + ultimate juice + brightness on 30% or so I still have 29% battery after a full 25 hours. I would just disable NFC because I do not see it in my battery usage. It is only useful for Google Wallet, and wireless charging (correct me if im wrong).
I use the NFC quite frequently during the day by having various profiles set up around my house, and my battery seems to be fine. Are you using a custom rom or kernel? If the NFC battery issues always occur, I would try reflashing your Nexus. Seeing as NFC itself doesn't eat a significant amount of power, I would guess that the Android OS is being kept awake by the process.

Well I got annoyed and was one day from the end of my return window so I went to Verizon and told them I wanted another phone. They gave in and I just got the new one. Hoping the phone was the problem. I was unrooted with 4.0.2 installed. I don't have a huge need for NFC, but I don't like to think a feature of the phone was completely useless to me when I have seen others who leave it on with no ill effects.
Thanks
I know the GNex doesn't have the best reputation with its battery, but in the past couple of weeks, my phone's battery has been behaving very very strangely, and the problem is very intermittent.
Basically, I am seeing some odd battery drain issues, but there are a number of reported sources from looking at the battery information on the phone. Some behaviors that I have experienced:
1. Screen using 43% of battery with 22 minutes of screen on time.
2. Screen using battery when off.
3. Battery discharging down to almost 0 within an hour after unplugging it from being charged to full - no single app / resource reporting huge usage numbers, just a complete drop on the battery chart.
Other things I have observed; if I catch the system in a state where the battery is draining faster than it should, if I reboot, the system will often recover to normal usage.
I am currently using Paranoid Android 3.15 (I know they have updates - but they also broke their own PIE color scheme, apparently intentionally so, so I am sticking with the last known good version). I am using the stock kernel, and have not tried flashing a new one - if anybody has recommendations, I am all ears.
It is also possible that since this is the original stock battery that the battery itself may be going bad, but my observation about the problem tending to go away after a reboot makes me think the issue is not in the battery itself. I guess the ultimate question is, is there anything that can be done here? Or am I stuck with this until I replace the device in 6 months?
Welcome!
I have a strange problem.. I bought a second battery to my Desire - 'FOREVER' brand. Battery indicator says whole the time 100% or even sometimes 102%.. And sometimes shows : 20 % and that value get higher and higher.. I like that.. But Its not true value
If I switch the battery to orginal, battery indicator shows normal Value. I try wipe my mobile many times, changed roms and all that 'software' stuff... But still I have that problem.
And The Question : what wrong with my second battery? Its a battery problem? Or My Mobile? Or something else?
Its worth it to give battery to warranty? Any sense and hope, that they fix this problem?
Or maybe every battery that I will use it, not from HTC brand has a similar problem?
Please help me.
Thanks!

You've basically answered your own question:

You bought a bad battery, warranty won't be much help as they'll send you a replacement, probably won't work either. I'd return it if possible, go for reputable or official brand, read a few reviews before buying. Sometimes paying a bit more in this case is worth it.
Thanks for Reply. Now I trying to use program to monitor battery and Estiminate lifetime of battery after few cycle based on usage level by the user.
The battery is functioning normally. The only problem is then - when suddenly, my phone turns off .. i do not know how much time it will work. It's annoying because I always have to wait until it self turns off.
We'll see if this helps.
Hello.
My device is GT-N5100 with a custom KK TouchWiz based ROM
I have terrible with battery percentage meter incorrect.
Sometimes charging form 30% to 60% it's suddenly jump to 100% but still charging for a long time may be long than 1 hour to show battery full.
And sometimes with discharge ,battery percentage meter show much than 16% then suddenly depleted battery to power off itself.
I also ever face this issue from stock KitKat.
Any way to fix it ?
Same problem her

Hi, Yes I have this same problem. Don't know why it happens and don't know how to fix it. Charging for a long time and very little % increase leave it for a little while longer and it pops up to 100%. No idea why it does this.
I have the same problem, I have already rooted my device and tried some apps to recalibrate It but useless
A battery pull (I.e. disconnect the battery for 15-60 mins) will help reset the fuel chip, but the issue with incorrect calibration will eventually return over time. Rooting the device, installing Xposed and the Wanam Xposed module and disabling Dynamic Voltage Frequency Scaling (DVFS) once you've performed the battery pull helps a lot to prevent the issue from returning. Deleting Battery Stats does absolutely nothing.

Thank you very much for your suggestions.
I ever disconnected battery two times but it can not help just little different (before disconnect battery 50% after connected increase to 67%)
I will try Xposed module to disabling Dynamic Voltage Frequency Scaling and I will report you back.
I hope it will be better.
Your battery is dying. Change it to a new one. Buy a new one off ebay & do it yourself, its fairly easy.
His battery *could* be dying, but a bunch of us with Note 8s have encountered the same issues with reported battery voltages jumping all over the place resulting in the fuel chip thinking that, on average, it has 40% less juice before it thinks it's empty and dies. The net result is that many people are getting 3-4 hours of battery life, rather than the 7-10+ hours they should be getting. Someone on these forums tracked it down to how DVFS interacts with how the fuel chip gets calibrated over time and another person managed to snag a copy of the fuel chip's data sheet but the instructions on the sheet on how to reset the chip in software didn't seem to work, hence the battery pull needed to reset the chip to use its stock curves.

Thank you all.
I went the new battery route with a New Power 99 one from Amazon. Nerve-wracking as Hell to put it in cuz I didn't want to screw my device up but really was easy. Now zero problems. How long this will last is, of course, the question. But even if I get another year out of it that'll bee good. I suggest you try that.

It is too expensive in my country but it has 3 mount guarantee from Samsung.
Everything seems OK.
Problem solved

Hi everybody
I have the same problem with my n5100 device, my battery % suddenly jump when charging and when discharging. So, I have returned my tablet to the post sale customer service as part of 1 year of warranty, they have changed the motherboard and now it work perfectly:good:. Actually the problem was not related to the battery
After month testing with an ebay cheapie knoxed 4.4.2 Note 8.0... All Samsungs have DVFS in the Touchwiz's build. The only way to fly is to disable it with wanam kit or DVFS disabler or Wanam xposed. Though I rather live with unplugging and plugging back in the power than to deal with Wanam's battery sucking issues with KK. Until wanam is redesigned for KK, I'm staying away.
Hi ... I have a question about bn31 battery ... how do I know if the battery life is still good?
Using the multimeter, it marks 4.20v ... it means that this good or I need to change? the cell phone is not lasting for 6hrs of use and the battery is gone. Would you like to know if it's really the battery or have something else with the phone?
Use AIDA64 app to check battery health
Hi. Thanks for informativo. But i want anything more physical...no app...i don't believe much in the app's :good:

Used AccuBattery and then use your phone as normal and let it charge for 4-5 times, then you will get the estimate battery health left from your phone. Screenshot is from my Mi A2.
You know it's good if it doesn't look like this:
Late reply.
I'm using AccuBattery App since March 2019 and its working very well for My MiA1. I trust it after cross-checking with alternate indicators.
Most important is the time spent in Deep Sleep. If you get zero or small percentage of time in this mode even after overnight inactivity, your mobile has background apps that are consuming battery.
I have been using Greenify App for many years and it helps cleaning up. I think it's a necessary App.
Try the following:
Shut down the phone. Reboot from Cold.
Put the Battery Saver ON w/o doing any other app launch.
Do the same thing first, after every Charging.
Every morning, I check the Deep Sleep. I do get additional ~6hrs (same as your sleep time). The average discharge rate falls to 1 to 1.5%/h.
AccuBattery does help, working consistently for last 8 months.
