Hi,
I'm sure this type of question has been posted here before - I've seen a lot of the posts. However, I'm having lots of trouble finding a good answer for my problem.
I'm using a Verizon Galaxy Nexus with a custom JB ROM and the latest radios. My problem seems to be that Cell Standby takes up a ton of my battery. This problem existed in ICS (stock and custom roms/kernels) and with JB (several custom roms/kernels). I've noticed if my WiFi is left on, the problem is immensely better. It's 3:20PM and I'm sitting at 87%. I'm on about 6 hours standby and that's all on WiFi, no use. If I'm on WiFi, that'll be about 60%.
It varies of course depending on what I'm doing. I've noticed that phone calls use a ton of juice and the screen obviously uses a bunch, too.
Also, it doesn't make too much of a difference if I'm running on 3G or 4G. I prefer 4G as it seems a lot more consistent in staying connected, but I've opted for 3G to keep my battery at a decent level.
OH! And the only thing I have running on my phone right now is an Exchange account, Gmail and Google Voice. Google Now is turned off.
Has anybody experienced this sort of thing? I just can't understand how the iPhone can sit idle for days and my phone can't make it past 24 hours unless it's on WiFi.
Thanks,
Jack
I have had my Note 8 for a couple of months and just recently I have been having battery problems. I restored the Note 8 to factory settings (just to be sure) and am still having the same problem.
It seems that when I watch videos or play any games the battery depletes extremely quickly e.g Its 80%, I start to play the game and within 3-5 minutes the battery is 30%. I play again and its 5% and the screen dims (which is also a pain in the ....) I realise that Games and Apps use a lot of power but surely not this much.
I have looked around for battery calibration instructions and apps but are a bit dubious to try them as I have read that you can deplete the battery totally and the device then wont charge.
Just wondered if anybody else has had the same problem.
Thanks.
My note has a great battery life. For this situation I would look in the battery menu for any apps not closing correctly thus sucking battery. Remember to dis activate GPS, Bluetooth and data when not using them. Check the screen brightness is 50% or less. Automatic brightness should be fine also.
here's a lot of info related to batteries. I'm sure you will find it usefull

Don't waste time with calibration. Sounds like the battery ifs failing or dying, either way it's bad.

I usually have Bluetooth and GPS turned off and have the screen on Auto Brightness. I also restored to factory and the problem still persists.
One strange thing is that when I charge it from 10% it takes about 50 minutes to get to 100%. I thought that was a bit quick. The battery must be reporting the wrong charge to the OS. I wish they had user replaceable batteries in this thing although its probably not practical.
I will give Samsung a call. Cannot beleive it has happened now as I am off on holiday soon to the US and wanted to use it there.
Thanks.

Hi, I've had the same issue. I sent the device for service under warranty and they could not find a fault. They only reflashed the firmware.
Its been working fine since I got it back. I updated to 4.2.2 and its working just fine.

same with me chas0001, and JCUK89, my situation is actually identical to chas0001, but my device is like a mth old now, i received it on august 5th 2013,
so its basically been used for jus over a mth now. and i barely use it, maybe 3 hrs a day, most days less than 1 hr, constant use.
i dont kno, can anyone help. on xda developers. ??
I called Amazon.co.uk (where I bought it from) and they agreed to replace it for me. Its was definitely faulty and unusable. I kept reading about people with the similar problems and so eventually decided to not get a replacement but a refund.
Its a shame really. I really liked the device but I need something more reliable. I also don't care for Samsung with their constantly delayed OS updates. 4.1.2 for a 'flagship' device. Surely if they get rid of that Touchwiz crap they can release timely updates. You never know even my Note 2 may get an OS update this year!
Just went out and bought a Nexus 7 (2013). NOW...what to do with those 5 Galaxy Note 8 cases

I would see of you can get it exchanged (assuming you still want to keep the device).
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.

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
I noticed that I have to reset the phone allot. If I am in an area with no reception for a while then go back to an area with reception it wont automatically reconnect and the LTE stays off sometimes. I have to reboot the phone.
The same problem is with signal strength too, it will not reconnect automatically sometimes. My 4G LTE does this allot. It does become annoying. I am afraid to get another phone in fear it will be worse then this one. I already had to exchange my phone and am running out of exchange days. (14 day period)
My first M8 I got on June 30 was slow, incredibly laggy and very buggy to the point it was nearly unusable. That first M8 had a mind of it's own. Maybe it was the first gen, I do not know. This replacement phone has been good to me minus the fact it sometimes drops calls and gets SUPER warm RANDOMLY even when ALL the apps are closed. The new phone is MUCH faster with the same settings and runs much smoother.
These connection issues are bugging the hell out of me, my iPhone never had this problem and would always reconnect fast. I do not like the S5 and I like the HTC but I do wonder about it's quality control and the quality of the internal components inside.
I hope its not hardware. I hope an update fixes the issue I'm constantly restarting.

good day - i have not had any of these issues with the m8 at all. has been snappy since day one. i have had little to no connectivity issues either. i have gone from way out in the country back into coverage, 2g snaps on immediately, then 3g, then closer to the city, 4g. my wife and i have a family plan and both devices switch within seconds of each other. different phone, she has the g2 but zero connectivity issues there too. we are in northern IL / Chicago market so it might be different. might be a dud phone? i do not think it has to do with hardware quality though. i went from an htc incredible that i had to replace a speaker in after 10 months but had no other issues with, to an incredible 2 that i had 0 issues with, to a S3 that was awesome, to a note 3 that was great, to the m8 which has been wonderful. my wife went from a blackberry that was crazy solid, to a S4 that was total CRAP, to the G2 which is amazing. if you can i would try and get a new one?

Hey, thank you for the response.
I went to T-Mobile today and they Factory Reset my phone.
I left to mobile and they told me to come back within 24 hours there is a failure
I ended up having a buggy phone with artifacts and flashes similar to an overclocked GPU. T-Mobile told me it might fix the phone.
Tomorrow, I am going back for my 2nd replacement. I like this phone, it works much better then my first phone but the connection problems are extreme and it starting to feel like faulty hardware. My first phone was full of lag, it was factory reset and lagged on the machine as well. The machine(a laptop) even had to be restarted.
Some guy had same issue and replacing sim card fix it. You should give it a try

I read (in the note 3 forums i think) that data dropouts were an inherent problem in android 4.4.2, and the code was fixed in version 4.4.3. Don't know if it applies to this phone as well, but if its an android system problem it could be.
This problem is really annoying happens too often.

Yeah it's happening more often that I would like but it's not a daily thing
My Pixel C is due to be delivered in the next couple of hours and I have a few questions for you seasoned owners:
Is it worth unlocking the bootloader given the 30 second delay and any problems this might cause getting Nougat?
Just how bad is wifi for you now? (This could be a major issue for me as I use my Nexus 10 in my garden at the absolute limit of coverage.)
And does the latest (final) developer preview make for a decent daily driver?
Thanks in advance.

DP5 is very stable and worth the change. I have not unlocked my bootloader due to the delay.
The WiFi is bad. Really bad in my opinion
The bootloader delay is annoying if you restart your tablet a lot, but why should you do? So if you are not shutting down your device at night or every time you dont need it, it should be fine.
The 30-second delay is trivial (to me.) I think it's an odd and intrusive choice, but it's never been a big deal.
I've never had any trouble with the wifi, although it sounds like the mileage varies. I don't usually care how many bars there are as long as it's not dropping off.
So far, I'm very impressed. I've tested the WiFi and, although the speed drops off, the range is really good, probably better than my Nexus 10.
I'm not going to unlock the bootloader, so far I see no reason to.
Nougat is great, zero issues.
2 apps won't work and one screams on loading, but that's about par when moving between devices.
It looks and feels like a really premium device, in real terms it costs the same as my Nexus 10 did at the time but this comes with a keyboard!
I just got my replacement and the latest build of Nougat is awesome, I've been using it as my DD without issue. I can't attest to the wifi because my apartment is small and my neighborhood is crowded.
My main problem is transferring files and getting ADB to recognise the device - I've had both working and now neither is, which is really puzzling and frustrating!
WiFi is bad on mine, on the latest N preview. It picks up my WiFi, but the speed drops from 36mb to anywhere between 2 and 10
This is with the router in the next room

The wifi has been driving me crazy, frequent drop outs, massive speed drops over distance - I'm returning it; which is really frustrating as everything else about it feels so premium, but to release a device they know is so badly flawed and still charge so much for it?!

If you're using Windows, check device manager and make sure the drivers are installed.
if you're thrilled about the device (like i do) file an RMA with google and they'll send you a refurb but updated Pixel C (serial# should start with 620xxx). I assumed that those with horrific wifi or screen problem probably has one with a serial number beginning with 5A or 5B. Check this thread to see if the one you have is cursed: http://forum.xda-developers.com/pixel-c/general/mapping-problems-to-serial-t3274660
Got my replacement yesterday and so far wifi has significantly improved. When im in the backyard, i noticed that wifi would disconnect about every 10-15min but with the new serial#620, wifi strength is about the same but I have not experience any disconnect around the same place. Hopefully the screen issue hold up on this one as well...
As for bootloader, I have a rooted phone with unlocked bootloader as my main so I'd keep the Pixel C completely stock. I havent found a need to do anything to it yet.
I've had my pixel c since it was released. Don't have any issue with it on wifi... this includes using it throughout a 2500 sqft house that is old construction (lots of natural signal blockers) and in back or front yard. It works about as well as an iPad does in the same environment, perhaps a little slower max speed at the more distant range, but no drop-outs and fast enough to handle HD streaming at the same distances.
For an android tablet I'd still consider it the best that is out there, although the nvidia shield is a cheaper option.
My serial number is 5A22000040. I bought mine in May and have not experienced any of the problems I read here. No screen tints or light leaks. My WiFi has never been an issue. I have run SpeedTest several times and the Pixel does the same as other WiFi devices I have.
I do get a screen blink out every now and again (more than a flicker) but I only seem to notice it when playing Spider Solitaire so I think it is application dependent. Otherwise, this tablet is smoking.
And for a bonus, I through my tablet into my Harley saddlebag (inside a Glock hand bag) and have ridden for days, using the tablet for nightly movie entertainment. I would say I stress it pretty well.
