[Q] HELP!! S-off device has battery drainage problems due to Android OS

Hi there,
so i gotta HTC one x last week, my first android..and I've gotta say that so far im hugely disappointed.
The phone has been draining battery like crazy ever since I got it. I've been charging it more than I've been using it, while it runs for no more than 4 hours when fully charged and heats up quite quickly. The battery usage options shows that the battery is being used mostly by Android OS and Android systems (over 85% for the former).
My friend suggested that i install a custom rom because it might be that the OS is corrupt. I bought the phone brand new and it came packed with an ICS stock rom. In the recovery mod the phone states that it is an S-off, with a CID #111111.
So i flashed the phone last night and installed a Jelly Bean Bindroid rom but the problem still persists. The phone drains the battery even when on stand by.
The phone runs fine besides the battery running out way too quickly issue.
Could anyone please help me with deterring what the cause of this problem might be and if the S-off thing has anything to do with it? and if so, how can I solve this battery problem? could it be a hardware issue?
Please help me. Im a NOOB at this!!!
Thank you in advance.

Might be a faulty battery. Look for a replacement OEM battery.

Check task manager too see which apps are running. Disable background sync if it's enabled, delete htc sense account if you have added it in account settings (it's a real battery hog).
Also, try to charge the phone to 100% battery 2-3 times and then check the battery performance.

Use BetterBatteryStats (search on here for the apk and instructions on how to use it).
Or, factory reset.

[Q] Should My Battery Go Down This Fast ???

Hi,
Yesterday I bought an HTC One X and over-night it was charging and when I took it of charge at 11.30an to go out to my nearest costa to meet some friends. I was just surfing the internet, facebook and answering a few texts. Come 1.45pm my battery was down at 19%. Im just wondering if it should go down that quickly. I know One Xs have 1800maH batteries which is bad as I was used to a Note II but sadly had to sell it.
The phone is very nice, screen is great but battery lets it down. Any ideas ????
Thank god Costa had charging sockets haha!
Thanks

if you bought the device brand new then it's unusual, if it's used, unlocked and running some custom rom and kernel (which, when you ask a question like that you have to specify in your OP) then it's likely that you need to flash a different kernel. On another note there could be a hardware issue, battery or cpu, does it get hot or laggy?

My battery today all on 3G. Brightness Dim. Insercoin. Can't complain.

Hi,
My phone is used but only 6 months old and I contacted HTC and they said a cache partition to reset it or something so will give that a try.
Thanks Guys

Here is a couple of things I'd do and you'll be able to see exactly whats happening.
First:
Download an app called "Wake Lock Detector" from the playstore. HERE
Second:
Download BetterBatteryStats HERE
Have some normal use for a day or two, let it settle etc, then at the end of the day CHECK BOTH apps and see what comes on top.
You'll be able to see which apps / services are draining battery, if it is apps using a lot then remove them unless important.
If apps don't seem to add up to the amount your using, it could be a battery or your voltage limits.
Hope this helps.

Frustrated with 4.3, thinking of downgrading

So I flashed the latest and "greatest" Android 4.3 on my Galaxy Nexus. After all, this is why we get our nexus devices for, right -- getting the latest updates without begging cell phone vendors or carriers. But Android 4.3 on Galaxy Nexus is driving me nuts -- A full charge won't last me for half a day without much usage at all. The phone intermittently wakes up and won't go back to sleep again, and after I press the power button to put it to stand by, it wakes up a few seconds later. Granted, it's not like that all the time, but it's often enough to be annoying and it's eating the battery alive. Before you ask, yes, I did do a clean install with root.
Very frustrated with this update, and come to think of it, the Android updates of late have not been stellar -- I experienced system random restart when 4.2 hits, and now this...
Sorry for the ranting but I'd like to know if anyone else has experienced similar problems. I googled around and there's an reported issue of Galaxy Nexus battery drain but given the discussion on there I don't think Google is going to dedicate any resource to fixing that.
Which JB point release do you guys think is the best for Galaxy Nexus?

Maybe battery life is not the best one, but you should let the phone settle some days.
The wakening problem is not 4.3 related. Indeed maybe its a usb port/pin problem.

Have you narrowed out that it's none of the apps causing issues?

As personal experience, much of what you describe did happened to me some time ago and it was cause for some apps that were not optimized for the newer Android API version.
That said, you could try boot into Safe Mode (keep pressed the "Turn Off" at the shutdown screen) and see if keep happening the issues you describe

Use Wakelock Detector app to identify what's draining your battery unusually..

Way ahead of you, I need my tethering.

The waking of the phone is most likely caused by a USB malfunction. 4.3 isn't great because Verizon hasn't updated the Nexus radios so the signal is very bad. It goes from LTE to 3g to no signal and back. It does this so ,much that the battery takes a big hit. Find a ROM where you can turn on and off LTE, that should improve your battery.

The battery drain is because of "always searching for nearby wifi" option
Just disable it ...

ive been happy with 4.3 on my VZW Gnex except for constantly having data issues. i downloaded a couple 4.2 roms again to see if they help any. I'm guessing it's because VZW doesn't officially have 4.3 on the Gnex which is why we are seeing data problems. I don't know specifics, maybe binary problems, i dunno. All i do know is it's annoying. I can't even stream iheartradio or pandora at work without it constantly cutting out. then i'll lose data all together and have to reboot the phone to get it back.

I just had this exact problem and spent a day working on it. It actually has nothing to do with android 4.3; its actually the usb port on the phone, as stated a bit earlier in this thread. More specifically, the pin inside the port is likely shorting with the outer surface of the port, due to it bending slightly. This causes the phone to have funky voltages being detected at the port, and results in the phone behaving as you described (the waking up when the screen is off is actually it thinking its going into charging mode). There are two things to do to fix it. Firstly, take some compressed air and thoroughly clean the port out. Dust that accumulates in the port can cause problems like this, and blowing it out is a relatively simple task. If that doesn't work, the next thing to do is to bend the pin up a bit. Note that this requires you to be a bit gentle, but is not overly difficult. Turn the phone off and remove the battery first, then wedge a very small flat head screwdriver between the pin and the bottom of the port. Very gently apply a bit of pressure, just to bend it up a bit. This doesn't need to be by a lot, in fact when i did it, i could only barely even see a physical difference. Put the battery back in and power the phone back up, and see if it was enough. It fixed all my problems when I did it a week ago.

Don't know what seems to be the problem here
Lasts me 1.5 days with 4hrs On Screen Time Every Time
Don't blame 4.3 if it's an app messing with your battery life

Thanks everyone for chiming in. Here's an update. I uninstalled Go battery widget and now the battery lasts longer. Not as long as I had hoped but better. I installed wakelock detector (thanks for suggesting it) after I uninstalled Go battery widget so I don't have the evidence to prove that Go battery widget is the culprit but the phone seems to be running better now. I also haven't experienced any random wake ups.

Would the data issues more likely be a factor of radio, rather than ROM?

Why do that when you can complain on a new thread on xda?! 4.3 sucks because crappy Go apps create wakelocks!

I had the same issues with battery life when I upgraded to 4.3. However, I largely attribute that to T-Mobile's horrible reception in College Station, TX. I used PA, CM10, Purity, Avatar, and a few others but the battery life and performance was not respectable even though they claimed the contrary. This phone is reaching its the end of its product life and no matter how many "optimizations" go under the hood, the hardware is just not apt for ROMs designed for higher end phones.
In the end, I flashed a stock rooted ROM, no more "optimizations", "tweaks", or "improvements"...just a clean ROM. Granted, I in no way mean to offend any developer and their hard work but my experiences with their ROMs left a bitter feeling towards them.
Battery life improved significantly. What used to be 100% to 30% in 8-9 hours turned into 100%-50% in 14 hours. Do keep in mind I'm not a power user. My phone serves as a music player for my ~1 hr commute from and to school, occasional text messages, random redditing, and the random news article before class. In all, I average a little under 2 hours screen time before I deplete the battery to 5-10%.
It's also important to use the appropriate radio for your market.
TL;DR - Try stock and a different radio.

Kernel
I have always seen major differences between Kernels and attributed the majority of battery life to that. Some kernels just work better than others. For example, I know that TONS of people love Franco's kernel, but on my phone battery life is terrible on it. Personally, I like Golden and it seems to really improve battery life.

Same here. I've been having constant data issues with 4.3. So much so that I've just lock myself to 3G and so far, that's been good. 3G->4G or back doesn't work half the time and requires either toggling airplane mode on and off, or rebooting the phone outright.

Going to have to agree. I have VZW and all the 4.3 ROM's I've tried have been less than impressive. I obviously appreciate the dev's work but nothing i've tried is ready to be my DD

Disaster suddenly

Hi all: I have been posting in the CM11 ROM for this device but I figured I would post my issues here and see if anyone has any insight or experiences.
I was on CM11 for 4 days with stability, speed and life was great. Last night I randomly got a reboot when looking at twitter. Fine, no big deal. 2 minutes later it happened again. Odd. I went into the play store and then it froze. I had to research and found out how to reboot it. Once rebooted, it would restart again. So, I went into TWRP, wiped Everything and then refreshed the ROM. Within 1 minute it froze again.
I flashed Stock and sure enough it froze on me. Noe I am annoyed and went to bed and figured I would deal with it this am. I plugged it in last night under 10% battery. Woke up 8 hours later and its at 14%. 2 hours since and its now at 17%. Clearly something is wrong.
Full disclosure---i bought a best buy geek squad refurbished unit and have done so many times with tablets with no problems. I am still within my 45 day return window and will probably just exchange for a new one since the refurbished price is the same as it was. Sadly, I wish they would give me a new one for the black friday price.
Has anyone had such experiences or have a clue what went wrong? Thanks

How did you flash the ROM? Tell each steps on how you flashed it. Did you mess with the CPU clock speed or anything? Did you also have any battery problems readings before flashing? I did a dirty flash of cm11 in which led to problems later, so I'm now on stock rooted and still works fine with no freezes. Probably tarp crashed? Happened to me.

I rooted via odin. I them used twrp manager to get the recovery and did a total clean flash. Wiped everything including system. NO I did not have any battery issues nor did I mess with cpu clock speed ( don't even know how ). All I did was use xposed to try the mutliwindow solution and downloaded lux and a material theme. Nothing out of the ordinary I don't think.

Either the battery is bad or could be something with the software. The only time when mine reboots is when I use to Much ram and it freezes. Other than that no problems.

I plugged it into another outlet. The outlet I always use charges me iPad and note 4 without a problem. I left for an hour and sure enough I got home and the tablet was at 100%. Yay. I started downloading my apps and noticed while still plugged in, the battery was at 95%. Odd. I took out the charger and Bam, rebooted. Off to best buy.

Wow it restarted and now shows 7 percent. I'll let you know what bb says.

Similar experience
I had a similar experience with my 2012 Nexus 7,it turned out that the connections between the charging port, battery and device were all faulty. They weren't soldered together properly when the device was manufactured (not as rare a condition as we are lead to believe either, regardless of manufacturer). I was lucky the I was able to take the device apart to check the problem without leaving any evidence that I had opened it, and I was able to exchange it. So from my experience, that kind of error always appears to relate to some form of battery issue. Also had it happen to me with a Galaxy S4, however it wasn't anything to do with the device itself, it was damaged connections on the battery.

Samsung galaxy S4 mini battery drain!

Hi everybody...I have this phone and I have a problem.When I charge the phone up to 100% battery and then take it from the charger,battery drops to 99 or less without phone usage...And when I go to sleep and then wake up,the phone lost about 10-15 percent...Can somebody plesase help me?

Check what's keeping your phone awake during idle, "wakelock detector" and "better battery stats". Though you need root for these. You've nor given us any details of what your phone is and what ROM?? Try searching for threads on how to calibrate your phone battery.

Ohh sorry...My phone is S4 mini GT-I9195 LTE....I have stock android 4.4.2 kitkat...I have already calibrated battery and bought new battery...But same problem...

Will be an app causing your phone to wake

I dont know...i searched on the web and someone said that stock kernel have some problems

Not always the case... Depends when and where your phone was made. Could be a faulty kernel or motherboard but it also could be an app or a setting on your phone or an unclean install. Have you always suffered this issue?

I got phone about 3 weeks ago...and the battery was very bad so i bought new one.I also tried CM 12.1 but the phone is heating in unnormal way but the battery there is better...

You have problems with motherboard. Go to service center to replace it on waranty.
Powered by CM12.1

But my phone isnt on waranty...i got it used haha....ahh nvm,i will live with that problem.thanks for help!

Bad luck then. Normal consumption for our device is 0.2 - 0.3 % per hour in stand by.

How long does yours battery last with some normal usage?

Almost 3 days with moderate usage.

Your best bet seeing as unless you pay for a new motherboard is to try one of the battery drain fix kernels on here. Though I think you may be limited to certain compatible ROMs.

Why are you not staying on cm 12.1? For me it's amazing, i observed at least 100% more battery efficiency than stock (4.2.2). I also observed the same problem with high temp too. But i think we can't have it all. When i play games and the outside temperature is about 35 celsius, i do not expect anything less, because this mobile is not designed for this android version. I think that's reasonable and i finally can use my mobile with a joyful way without having my mind always on the battery stats!

Thanks guys! And i will try CM 12.1 for longer time to see if anything will be better!
