follow this steps for some reason if u experience battery drain in mango
1.- Turn off the phone at 20% battery level .Switch to Airplane mode pulled out the sim card
2.- Turn on the phone without the sim card.
3.- Charge the phone to full. Turn off the phone
4.- Insert the sim card.
5.- Finally, turn on the phone.Switch off airplane mode
6. - Charge the phone again to full
U will notice that the phone takes longer to change from (Orange to Green LED even though full) .Please let us know if it worked for you.
Edit- another I found
Under brightness set it to low . turn on auto brightness. Use the phone for a while
Then , turn off auto brightness. It should now default to low . Use the phone for a while. Turn back on auto brightness'.
How about playing the tambourine, or prayers?
All you're doing - it just disabling network access. It may affect some services and apps (they may temporarily suspend network requests/activity)
I mean some "hidden" WinCE services and apps, not a visible SL apps like IM+, mail etc. (but "airplane mode" will affect on these apps too).
So, try your handset in airplane mode, and you will notice a much-much longer battery life

I dont know what it does but apparently it seems to "reset" something in the phone or something related to cell signal.

Wouldn't airplane mode cause shorter battery life in theory, since your apps are going to be reluctantly searching for a signal until they find one?

"Something related to cell signal" affects to the battery not too much. Powerful CPU & GPU, network adapter, large display, bugs in drivers/software are real power consumption "eaters".
P.S. You guys may believe whatever you want. I'm professional and I know - there are no miracles and magic rituals in high-tech world
You and your "advices" again?
Perhaps if you didn't spend every moment of every day trying completely random combinations of charging your battery, draining your battery, removing your battery, removing your SIM, drawing a chalk circle around your phone and chanting, searching for conspiracy theories, measuring completely arbitrary values and assigning them meaning, putting your phone in and out of airplane mode, rebooting your phone, changing random settings, etc.....you might be able to use it as normal? I highly doubt all these magical procedures have helped your battery life.
The HD7 has poor battery life, just face it. Not only does the data connection suck battery like nobody's business, but so does the extra large screen, and that's never gonna change.
Mine will still last a day though, if I don't spend the whole day fiddling with it.

Before u dispute me, the iPhone also faced similar problems related to signal and sim.
Android phones also have this time without signal issue.
While this matter is related to cell signal strength . Parasitic. Load is another thing .
Yr phone battery lasts longer when no apps are installed because no background updating thru sim signal ,hence no parasitic load.
Parasitic loads induce mini charge cycles.
when u install more and more apps which run in the background , u start to notice the battery indicator getting inaccurate . because the is indicator measures the amount of power charge and discharge the phone is doing to shoe battery level.
I hope u are really a professional
I agree the hd7 battery sucks but all of my methods at least a few of them has worked for others.
I also do notice that the hd7 lasts a good 20 mins long at 0% before shutoff.
This shows a problem with either the battery or the os indicator.
Htc has updated the firmware and radio 3 times

Are we still talking about phones?
I've noticed a substantial reduction of battery life on my HD7 after updating to 7720 and am still testing possible fixes. The original poster may not have found a solution (I'm testing his procedure), but I appreciate the fact that he is trying.
When I was running 7720 BETA, my battery life was NOT good. After loading NoDo RTM for HD7 and then 7720 RTM, my battery life is much IMPROVED.
Kind of curious if this method will improve battery life more.. ;-)

What are you "trying"? Are you working on MS in WP7 team? Are you hidden genius firmware engineer with full Mango/drivers source code, bunch of in-circuit emulators, scopes etc. Or may be you work at HTC or Samsung hardware R&D?..

what u mean I mean int this the normal upgrade method??
This method I tried above ... Am getting battery life for a full day with light ,moderate usage with 20% left by 10pm night
Basically the wp7 indicator measures the amount of battery yr phone is getting . If a parasitic load like sim signal and background. App updates are going on. The battery indicator becomes wrong and induces mini cycles on the battery . So that's why u need to charge the phone without radios or power consumption in the background .
This will truly charge the phone
Its the charging indicator which is wrong during the charge process as the phone is still under a parasitic load power consumption
Hence giving an inaccurate charge level relative to discharge when using the phone.
That's why u see the battery drain effect
This is also why the bump.charging technique works because no parasitic load .
To explain in simple terms
Imagine u have a fuel tank with measuring gauge on it.
U pump the tank with petrol (charge) The gauge only measures the amount of petrol that is pumped . But when the engine is running (parasitic load ) it uses up some of the petrol but the gauge does not know this has it only measures inflow of petrol and not the true amount in the tank .
When the gauge shows 100% full . Maybe only 80% is left in the tank , due to parasitic load when the enging was running during charging. When u unplug the petrol inflow. The gauge then starts to measure the true level when the engine is running (discharge) without petrol inflow
in the tank and from 100% it rushes down to the 80% to correctly reflect ,hence giving the battery drain effect as if the battery is draining fast.
Are you auto mechanic or work on gas station?
P.S. It's my last post here, dear believers
The suggested battery / SIM removal procedure has not restored my battery life, which remains seriously compromised after the Mango update.
I bought this amazing [As you all know how fast it is ] Galaxy Nexus and was previously using hTC Desire S[GB] !!!
I'm somehow not happy with the battery life and also the overheating of Nexus !
It is Stock[ROM + Kernel] + Root ! around 7th or 8th charge cycle !!
I did try out Cpu Sleeper App works like a charm but was facing reboot issue and that is why had to remove it !!!
See if anyone of you could help me overcome these issue ! or Is this really something for me to worry about !!?????
[PS: Please don't recommend me to change ROM or KERNEL ! Because I prefer to stay on Stock ! Also NOOO Overclockig !]
Check out the Few screen shots i took when my brain kicked me to !!!
We need to see the screen before this one(the one that lists top consumers of battery). To see if something is waking the phone up. Also, charge cycles and calibration are bogus. If anything, you would be using the phone less since you've finally set everything up the way you want and the newness effect has worn off. My battery life has been about the same if my usage pattern remains like it usually does throughout the day. It doesn't really look too bad, but the drops seem a little steeper than what I normally see. . Grab CPUSpy and BetterBatterystats. I'm on my way to work soon, but someone may be able to help you before I go on break.

Here we go
ok so calibrators and cycles are bogus ! I get that !
What about brightness ? Should that be auto or manual mode ??
And is Google Now causing issue ?? Because its not really useful to me on daily basis !!???
And any other suggestions your would like to share
I was gonna edit my post, actually. I've personally never fully charged and drained my battery for any of my phones(some people swear by it though). I guess if the readings are out of whack then yes. My phone got stuck at 85% for almost 12 hours one day, but I had did something which messed up the OS. Haha.
If you don't use Google Now, you can opt out of it. Brightness is a personal preference. I usually stick mine at 25%. Auto may take a hit on the battery, but I doubt it's anything to worry about. Just the common sense stuff. Apps that poll data in the background will drain the battery, but if they're properly coded, they shouldn't be a problem Running on 4G/LTE/HSPA with a bad signal will drain it more since the radio is trying to find the best possible signal. After a full day of use, what is your typical screen on time? 18 hours is pretty good if you're using it on HSPA all day.
ya honestly that doesnt appear to have anything wrong. What results were you expecting vs what you have? You have a lot of screen on time, that takes a LOT of battery to run the display and using it when brightness is high takes significantly more. Also it appears you have a couple long phone calls in there as well. As far as heat goes, youre going to have that on the higher end phones due to the gpu producing heat and oled displays produce a bit of heat as well, lcd runs cooler.
Weak/unstable/unrealible mobile network signal could cause the fast drain of your battery. I saw you have one bar of hspa signal in the 3rd screenshot.
Those graphs should be much flatter during idle periods. Something is keeping awake. If you're on jelly bean its prob Google now. It does it to everybody.

Actually 3G isn't really well established for Vodafone[or any other company] in India.Also there is a peak going upwards in the first image indicating charging and after having a battery life of around 20 hrs on My Desire S and screen on [appx.] 7 hrs , I'm very disappointed with Jelly Bean !! Also While googling this issue I found out that somebody sniffed the mobile wifi connection to monitor and found some app constantly exchanging packets which according to his test was the root issue for the battery drain !!
Edit:
]Ok I found the way to shut google Now !
I'll records stats for a day or two and get back Thanks Everyone for your time and help

In Google Now >> Menu >> Settings >> Google Now there is an on/off switch at the top. Depending on the ROM it's included as either velvet.apk or QuickSearchBox.apk but removing that would get rid of Google search I think.
Yeah. I think its actually part of search. Like I said, just opt out and you should be good to go. Keep us posted.

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.

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.
Hello, unfortunately I haven't been in possession of my phone for a good amount of time, and I believe when I lost it the battery was run down to zero percent. IF I ever manage to get this device back, will there be any major battery issues I should be worried about? The device was only a few weeks old when I lost it. If anybody can answer this, I'd appreciate it. Thank you.
I'm sure it'll be fine if you do end up finding it. Battery issues might only arise if you're constantly discharging to 0% which is harmful to the battery. Once should not make a big difference.

So the fact that it's been dead for so long won't have an impact on the battery life? I only ask because I read something about that not being good, but I don't know how old that article was or if it's even still applicable. Thanks again.
In actuality, the battery voltage is not even close to zero, when the battery meter says zero and the phone shuts off.
The battery has safeguards to prevent the battery voltage dropping too low (too low, and it won't take a charge). If/when you get the phone back, leave the phone on charger overnight, and see if you can get it working by holding down the power button for several seconds.

That's very good to know, I'll keep that in mind. So from the information posted so far, it's safe to say that this scenario will have NO negative effect on the overall battery life?

That is not at all what I am saying. Li ion batteries should be stored at a certain voltage level, otherwise negative impact can occur. Its also possible the voltage has dropped by this point, that the phone will not properly take a charge.
If/when you get the phone back, try to charge overnight and see if it will power on. Otherwise, another option is to find a repair shop with a battery meter with a "boost" function can sometimes bring Li ion batteries back to life after the voltage has dropped too low. But the phone may need to be opened up to do this.
Just want to know your thoughts about having wifi or Bluetooth enabled all the time, even with no connection or pairing with nothing, regarding battery life
I ask this because my test would not be accurate as I always use the phone differently (moving to different places, calling, music) apart from playing with kernel and other settings... So can't really tell the difference in that
Please don't tell me, just turn them off when leaving home or leaving your car. My point is to get it connected/paired with no need to unlock phone, turn on... etc... xD
About NFC I saw a module to enable it when screen off. But I read comments that it causes big drain, obviously
On the previous build MH19C I was pretty sure if wifi 5GHz is enabled and available, it will drain and also wake like crazy. This happens in my office but not at home where I don't have a 5GHz wifi or even wifi ac, but is widely used in office, with multiple physical AP's. Now already on the May update, I no longer enable 5Ghz wifi and backgroud scanning just to be safe.
Less than other devices due to the Android Sensor Hub and Doze.
while not in wifi i have data which drains tons of battery anyway, so i dont even bother with any miniscule effect wifi scanning might have. i would advise you to put it off your head too, there are thousands of tiny unessecary battery drainers in your phone, it would sap your mental health trying to deal with anything more than the big ones (data/screen/bugged apps) for only few % of battery.
if the phone is able to last till bedtime or return to home, then it does not matter to meddle with anything. charge it every night and if comes to worse it charges to 50% in few minutes
Thanks for responses

Exactly, that's why I want to know if the % is noticeable or not
It's a good advice. However it's also good to keep things in order because battery cicles are limited in phones and my goal is to keep the 5x more than 2 years xD
So I wouldn't be fine just getting at the end of the day, it's good to preserve and not drain unnecessary drain, considering this battery is not removable, plus it is already 'bad' being new haha

i dont know about battery cyrcles, but replacing battery on 5x is not hard - watch a video about it as to not make any hasty mistake, and its piece of cake.
also its better if the battery is not too low when recharged and not too hot. 5x already has a annoyingly protective temp threshold so you dont need to worry about ruining your battery that way, while its better to recharge every night (or more often if you need) even if there is plenty of juice in the phone cause that is healthier for the battery.
If reducing battery cycles is your main goal, you have to turn them off.
I'm keeping wlan (connected at least 50% of the time with decent-v good connection)/bt (most of the time no connection, only in car and for bt speakers) switched on all day and they together take 7-8% battery on (my) average use (~10-15% left before charging every night), of course much less (in relation) when heavily using the phone.
