I have been getting excellent battery life with my EVO running Baked Snack 1.7 and Netarchy's kernel. Typically I'll end the day with ~70% battery left.
Last tuesday however, I went out to the US Open in Flushing, and it was drain city. When I got home, I had ~20% battery left. Keep in mind, I had full or mostly full bars the whole time, so I don't know that it was really a signal problem.
Weds-thursday, my battery was fine as I stayed here on Manhattan and was back to getting my ~30% total drain in a day.
Last night I went back out to Flushing again for a Mets game, and came home with ~18% battery left.
WTF? Is there something wrong with my EVO? I had heard a rumor about these phones having trouble connecting to Motorola towers or something like that, but not sure if it's true. Is there anything I can do to fix this?
Stay in manhattan.

is 4g enabled while in flushing and not in manhattan?
If in Manhattan, your phone is connected to WiFi access points, it will favor that connection over 3G and its time syncing data using that lower power radio. When you are not around a WiFi point (maybe when you are in Queens), your phone is forced into 3G.
One thing that will help in general, is to make sure the following is set:
Settings / Wireless / Mobile Networks / (uncheck always-on)
Thanks - much appreciated. Unfortunately, I had wifi off, and 4G off as well, so I don't think it was related. I typically keep wifi off when not at home and don't see that much of a drain.
It happened again today when I was visiting a friend in Dumbo. It seems like the phone is constantly searching for towers, even though it has a connection. I don't know.
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 been using CM10 for awhile and usually find it to be great. However recently I have noticed my phone doesn't seem to last a full day anymore and this is minimal screen time. I updated to CM10.1 (RC2) when it was released, I'm not sure if that contributed or if there's something else I'm missing. I have found the best performance by disabling LTE and using WiFi whenever possible. Still though it lasts 9 hours with about 1h30m screen time. If I use it anymore the battery may only last 5 or 6 hours, and this is just using it for occasional web browsing and some texting.
My service provider is Koodo (Telus) and I live in Burnaby BC, so I usually have a pretty good cell signal.
I have attached some screenshots of my battery usage. This was on a day with only light usage and no music or media used; LTE was disabled and WiFi was on.
Any ideas as to what could be causing this, or if this is normal would be appreciated.
Thanks!

Did you update your bootloaders? If so, you probably have the LK4 modem, I'd try flashing the LL1.
Also, you can download BBS (BetterBatteryStats) from here to help narrow down what drains your battery.
It has been known that CM10.1 has been giving poor battery life ever since the Linux 3.4 kernel rebase. I'm not sure if there is a fix, or if the CM guys are working on it at all... It has been 7 days since the last kernel commit for d2.

I can support this, I am getting about the same battery life as you. Ever since updating to RC2 I have noticed that my battery life has diminished. I have a spare samsung battery, and normally I wake up, boot and go to school and use my phone a fair amount for texting, researching, and music. A full charge will usually support this until around 10-12 hours later, then I change batteries in the evening play more music and web browse. I took a screenshot of my battery history a few days ago, you'll notice that the graph increases without the phone ever being connected to a power source.
Has anyone checked their "Cell Standby" to see if there is any time without signal showing?
If you haven't toggled your LTE off, have a look sometime and let me know. If it is showing a percentage of time without signal, go back to your battery life graph and see if there is any RED in your Mobile Network Signal. If you see time without signal but no red in the bar let me know.
I've got some ideas on why battery life isn't great and I'm trying to build a case for it. Guys who frequent locations with poor LTE (4G) signals are who I'm mostly looking to get data from.
Any information that you guys might have would be very helpful to me. Screen captures are welcome. I've uploaded a couple of myself to show what I am talking about.
Cheers.

Poor signal is one hell of a battery drainer. I would suggest trying different modems to find one that works better in your area.

No no. Modems do not affect this issue at all and with the new phones now a days modems don't play as big of a role as they used to with signal strength. Anyway this issue is bigger than that. CM10.1 isn't reporting 4G low signal strenght correctly. It jumps from -115 at one bar to 0dBm no bars instead of switching over to a 3G signal or showing a value that is accurate like -117dBm.
Flashing back to the M1 release of CM10.1 or even to stock and the handoff from 4G to 3G is seamless. We aren't seeing that anymore with the later released even as early as RC1.
Here is my JIRA report.
https://jira.cyanogenmod.org/browse/CYAN-1209
You can see I've put some work into it. Trust me, this isn't a flash a different modem, change network preferences or anything type of issue. I've tried all that before finally starting to gather some screen captures and information on the way the phone is handling it's network signals.
I've also talked about it extensively in the CM10.1 Nightlies thread in the dev section over the last week or two.
http://forum.xda-developers.com/showthread.php?p=41931891#post41931891
Also my original post was asking for anyone who has seen a time with signal recorded under cell standby BUT NOT showing any red in the mobile network status graph. Different than just no signal at all and red showing meaning you have no connection to the carrier at all.

I can probably come up with some data, when I'm at work I generally get a low signal, I never toggle LTE, though I live in a town of ~8000 people, far from major centres. I believe we have HSPA+, but I'm generally connected to 3G. Right now, I've had normal battery life, (no increasing), and 0% time without signal, should I ever have <0% I'll message you some data. Thanks for your work!
I can confirm that I'm having this issue as well. I live in a 4G city (Boston), but my high school has practically no 4G reception. I noticed that unless airplane mode is enabled in the school, I have a battery drain of about ~1 per 5 minutes. The battery stats shows certain red areas when the signal is close to 0.
I'm running the latest nightly (5/29), but I'm flashing back to the M1 ROM until this is fixed. If I encounter any issues with this ROM, I'm probably going to flash back to stock.
Hopefully the devs can get on this when they have time.

Battery life has actually improved quite a bit since rc2, but when I'm at school, where the signal is bad (most of the time I get "emergency calls only"), I see faster than usual battery drain as well. I think that this is normal though, because even my old dumbphone drained battery quickly when there was no signal.

Emergency Calls Only and Red in the mobile network history aren't what I'm referring too with my issue.
Those two things would indicate you phone had no cell signal at all to your carrier. I'm talking about being on such a poor 4G signal but still being connected to the Roger's network. It's hard to explain.
Anyway I appreciate your input.
There has been a lot of discussion on this in the CM10 Nightlies thread in the dev section if anyone is interested in reading or check out the JIRA report linked on the first page of this thread.

I'm still connected to the AT&T network, but it's a very weak signal when I'm at school.
Just flashed back to stock, and the draining issue disappeared. I guess there's still some issue regarding cell signal that's draining the battery.
I've got the same issue, I thought it was just me. I'm on Rogers
I even lose battery (about 1% every 30 minutes) while plugged in and charging, if I'm listening to music, and checking my phone once every half hour for texts or emails.
The other day at the gym while listening to music and using 1 note taking app, it went from 95% to 15%. When I checked, it said the phone was active for 1 hour and 5 minutes even though I never used the phone.
I'm going to install that bettery battery status app now.
has anyone else seen a dramatic decrease in battery life after the update? My battery went from lasting all day, to now Im lucky to get 5 hrs before its down to 30%..... overall ive seen a drastic decrease in overall performance... has anyone else expierenced worse performance?

keep calm and factory reset. That should fix the stability and battery life.

No better no worse, my battery life has always been great. Example today, unplugged at 7 am , no recharges during the day and it's at 55%.
I used the phone , surfed and checked my texts and email all day

You are not alone. I used to be able to go a couple of days on a single charge. Now I'm struggling to make it 12 hours on a single charge.
I was getting almost 2 days when I first started using the note4. After a few months passed I noticed battery life dropping pretty fast throughout the day. Factory resets helped a little, but not much. Lollipop upgrade plus factory reset has seemed to help. I get through a full day now with light browsing/gps(maps)/gaming and fair amount of spotify streaming. Nothing close to what I was getting fresh out of the box.
I am experiencing similar battery issues. Used to charge my phone once every two days. Now, I carry my charger attached to my hip like a feeble iPhone hipster.
I'm also having issues!
I also have seen a large decrease in my battery life since updating to Lollipop. I tried factory resetting twice and nothing seems to help. I was getting 8-9 hours of screen on time on Android 4.4.4 but now I'm somewhere between 4.5-5.5.
Also my note 4 will occasionally get really hot after just normal web browsing. I'm very disappointed in the update. However, performance seems to be a little better....but it wasn't ever really an issue.
I just read an article on gsmarena about the international version of the Samsung galaxy note 4 receiving a firmware update.....hopefully that fixes the problems we're having. We just have to wait for Verizon to send out the update. (Which will probably take a couple of weeks to months).
One thing to keep in mind is that we (those who are having these issues) need to make sure that we contact Verizon in order to make sure that they acknowledge the problem and send out a fix ASAP.
I'm having the same issues since the update...battery sucks. What's the easiest way to inform verizon?
Passpoint Wi-Fi
Noticed that there is a "new" Passpoint Wi-Fi feature that will automatically connect to certified access points.
This is ON by default after the Lollipop update. (Settings >> Wi-Fi >> Advanced)
I just turned it off to see if battery life improves. Never been a fan of automatic Wi-Fi connection features.
Checking on the Lock Screen Weather/Location Update next.
My Note 4 has the battery drain issue now after updating last night to Lollipop but am giving a couple days to see if any improvement. I did do a battery pull after all the updates (system and apps) and it did seem to help.
My Note originally for a couple of days had the battery drain issue. However, after uninstalling the Google Fit app then a reboot the battery life has been great.
Maybe try a battery pull for 20 seconds as well.

I think the easiest way to contact Verizon is just by talking with the technical support. Good representatives are hit or miss but Verizon's are generally good.
If you contact them just explain the issue that you are having and they should be putting it on record saying that multiple people are calling in concerning a battery problem. They may have even figured out the culprit (s) and/or found a fIx.
I'm going to be calling today.
Since I have updated on nougat, my battery quickly goes empty.
I reach a maximum of 2 hours SOT.
According to "BetterBatteryStats", the operating system consumes the most energy.
No matter whether Stock Rom or currently with "PureNexus" and ElementalX Kernel with GhostPepper profile, the battery is still very fast empty.
I also wonder what the Wakelock *job delay* and *job deadline* mean.
Now is the question, do you have the problems since nougat, too.
And is the problem the operating system or rather the battery, what do you have for experiences?
With marshmallow I had up to 5 hours SOT, therefore I will downgrade.
Whether it will be better, I will report.
im finding that when my WLAN is off then my drain is negligible. Whilst with it on i see a steady drain overnight.
That might be how i have my phone setup, but not sure.
I now have tasker setup to disable wifi, location, data and swap to 2g at night (i have terrible 3g/4g reception in my bedroom). it seems to help for overnight drain but not daily usage.
I have never had good battery life with this phone, by the end of the day it is usually almost dead with only about 1.5 hours of actual use.
I have the same feeling.
If you confirm that downgrading solve the problem, I will try the same.
Thanks!
Battery has been fine for me. Your phone is never idling properly from the looks of it, despite not being show an awake. Not sure what that means though.
Is there some issue with your WiFi or data signal? I've not seen the WiFi X myself.

I have not changed my settings so far, only slight improvements, which I have since I own the smartphone.
Mobile Data always to max 3g (have no LTE contract), GPS always on (only device), Wifi also always on and could reach thereby also up to 5 hours SOT.
Then I moved from the Google Stock Rom to PureNexus hoping it would help, well, wrongly thought.
And I have always done a clean installation. :silly:
I've been back for a day now on the last Marshmallow Rom (MTC20K) and I do not want to be too rash, but it seems to improve. :laugh:
I will continue to observe and report.
