I'm running the latest CM7 nightly, and I've noticed that cell standby is draining the battery. In battery usage, cell standby is anywhere from 50-80%, depending on how long the display has been on. And this is with a clean install (no apps, no google account sync).
The thing is, I'm traveling abroad right now so I don't have cell service but I do have wifi access, so I don't want to just put the phone in airplane mode. With other roms (I've tried stock and unnamed) there doesn't seem to be this issue.
Any ideas? Thanks
I believe it has no real effect on the battery life. It has been discussed many times and you should be able to search for it on the forums.

Is your battery ACTUALLY draining?
Remember, everything in battery stats is relative - if you reduce one drain source, the percentage for another will increase.
Cell Standby is a fairly fixed drain source - the only way to actually reduce it is to move to an area with stronger signal or put the phone into airplane mode. If it's high percentage-wise, that just means your other drain sources are very low.
Thanks for the tips
The battery did seem to drain faster with CM7 (not just based on the percentage of cell standby).
One thing I noticed is that with CM7 the phone signal bar in battery usage was almost all red, but with UnNamed it was mostly yellow. Could this be why the battery seems to drain faster with CM7? Would flashing a different modem help?
Hi guys, this is not an usual battery drain problem. I am more or less an advanced user of android but I´m writing here because I tried all my ideas and none of then worked.
I have 2 Neo V, stock. One day one of them started to have battery drain. Im talking about 6-7%/hour with no usage, the other one is around 1-2%. So with any use my phone don´t last more than 14h.
I started to check the usual(wifi policy, services running..), and don´t found anything, I switched the batteries between both to see if that was the problem but drain was still in the same phone.
I rooted the phone, tried BetterBatteryStats and CPUspy and all is OK, most of the time DeepSleeep etc.
After all I unlocked the bootloader with the S1tool testpoint etc and flashed some Cyanogen 9 rom + kernel, and the problem still persists.
I think there is nothing I can do and my phone is useless because I suppose I don't have warranty anymore.
Any ideas about what could be? Even if its hardware, what kind of hardware problem can make this high battery drain if the CPU is not working ?
Thx in advance
edit: In HTC we can also flash different RIL´s (radio interface layer) to improve signal db, avoid high battery consumes etc. There is something similar in NEO V? Because I didn´t find anything.
There are a couple things you can do:
1) Did you check that you had mobile signal all the time??, because losing mobile signal is THE biggest battery drain possible
2) Post some BetterBatteryStats screenshots so we can see what's happening under the hood
3) Try a different ROM/Kernel combination, that sometimes helps
And no, there's no RIL flashing here, just different ROMs/Kernel/Baseband combinations
I HAD the same problem
Even I faced a similar problem on my Neo V after getting FXP CM9. FXP 122 was fine. But FXP 123 and 124 drained the battery very badly(No considerable Deep Sleep in CM 9). So I switched to AOSP Polish blood. Battery life was excellent but it lacked customization, so I switched to AOKP v38+ AOSP kernel. Superb ROM but again not so good on battery (but better than CM 9). Yesterday I flashed the FXP 125 kernel. More than 5-6 hrs of WiFi, 15-20 calls and texting and some instagram and I still have 20%. I'm charging my phone now!!
I´ve uploaded some screens of bbs, cpuspy and batterydrain with wifi on and after switching it off.
Hope it reveals something, what really annoy me is the deep sleep activated most of the time, so I don´t really know what to search.
Just as I thought, what's happening to you is what happened to me a year ago and I thought changing phones would help.
Your problem is basically, bad signal, as you can see in screens 4,5 and 7,8 "No Data Connection" and "No or Unknown Signal" are preventing your phone from going into Deep Sleep, the problem comes from bad 3G signal (or just bad network signal if you don't have 3G) and that is known to basically eat up all your battery.
How is the network signal where you are???, because it looks like it's realllllyyyyy bad.

Are you sure? Take a better look.
Or at least deep sleep graph. And those graphs "No Data Connection" and "No or Unknown Signal", are also ok(ven though the name is confusing a bit), I have the same.
I'm not COMPLETELY sure but this is exactly what happened to me a year ago with a Samsung Galaxy Mini, also if you look at graphs 4 and 7 Deep Sleep doesn't have as much time as the data and signal bars, to me that seems like those two are keeping the phone in wakelock state more than it is spending on Deep Sleep.
I´ve been experiencing this problem for weeks. About signal I tried everything because:
- Phone worked perfect with SIM and all bars (I live in the downtown of a big city)
- When the problem started to happen I switched to another phone and this one was working without SIMcard so there was no signal at all.
- Some days ago I used another SIM which also have all bars.
I Don´t think there is a problem of the signal . Also in my other phone, and as you can see, Deep sleep is working fine.
I reread your first post and the only hardware problem that I could think of is a faulty battery, did you use to leave it charging all night??, because that tends to burn the battery and it does hold a lot less charge.
According to what I've read, everything seems to be fine software side, my only idea would be that you reflashed stock ROM and check if the problem persists, reflash but don't restore any data, the problem could be a misbehaving app.
I have 2 Neo V (my father´s and mine) I switched batteries, and the problem persist in the same telephone. Also both of them have less than 2 months, so batteries are new.
Also revised the voltage in the CPU and it is alright.
Well, the only thing left to check (IMHO) is a misbehaving app or service, maybe check for task killers or battery savers in the "broken" phone, those are known to eat up the battery like it's ice cream!!
I believe I have the same problem. I can't remeber when it started since I tried lots of roms,
but I flashed latest ICS from pccompanion with no other tweaks for some days and it
continued the same.
I also thought about bad signal, but at night in flight mode it also spent 40% of the battery.
With a good kernel, undervolting, 2G... I can get to 15% 20% at night.
I've also switched batteries with other neo's and no difference.
Phone is 5 months old.
Not sure if it might come from the rooting process. If I understand right, the 0% issue
that some were having was more of hardware issue (or I'm completely wrong?) Then maybe
there is also something related?

0% was a software related error (flashing GB 2.3.3 after having 2.3.4 broke the battery gauge firmware), however that problem doesn't exist on ICS, I find it reallt strange that both your phones have that problem, I've had my Neo for 8 months and the most battery I've lost overnight has been 10% (with CM9 and really bad signal).
Maybe the best thing you guys can do is send your phone to service.
I have a similar problem with my mt15:
when I buy my phone battery was ok. about two days with intensive social use, no gaming.
5 months later, battery drain begins: deep sleep and 8% per hour , airplane mode 8% per hour
tried almost every popular rom in development forum ICS stock, codename, tweaked, cm7.2, cm9, jjhybrid, KA, ...
tried every popular kernel: stock gb, stock ics, alliance, suave, super, nightelf, cm kernels...
battery drain happens while phone ON, happens with airplane mode, AND happens with PHONE TURNED OFF.
I thinked about battery fault. replaced my battery with a new genuine one. Same results.
If I remove the battery from phone, IT does not drain. 24h later battery is still 100%
So my neo has a hardware problem I think. And there are many people with same problem. look for "neo battery drain while off"
Neo is a buggy phone. you can be lucky, or not. but many people has these issues or 0%batt.
I give up!
After sony abandoned x10 mini pro (random reboots, eclair), I had given another chance to sony with neo. I like sony designs, but Im really tired.
sorry about my creepy english
Try freezing "Calendar" with Titanium Backup and see if battery lasts longer. It helped for me.

about battery drain when phone is off
its not consuming your battery while its off
when you are turning the phone on
cpu usage will be on 100% to run all necessary sevices and apps and most use goes to get signal
that's normal
i suppose its aroumd 3-5% of battery consume
im not gonna be at the same side with you
actually neo is a wonderful phone
i beated the score of sensation xe in antutu benchmark with it
just google it around the internet
there will be some fix mate..
Neo is not buggy at all maybe yours but not mine
this might work for you
i just found it
1-flash build 42 official rom on your device
2-root the rom (there are plenty of ways around internet)
3-flash this kernel via flashtool forum.xda-developers.com/attachment.php?attachmentid=780407&d=1321113977
4-now turn on the phone its gonna show 85% of battery
5-install this forum.xda-developers.com/attachment.php?attachmentid=897721&d=1329003275
6-plug the charger into your phone
7-from the menu of app select start full charge
its gonna take 3-3:30 to be full
may be you've seen it around web
i translated it from a persian forum
HIT THANKS IF I HELPED YOU
In my opinion, a phone broken by a software update/downgrade is buggy.
About battery draining while off, not all neo have this issue, but mine is not the only one.
On the other hand, about power consumption while booting, if i remove battery while off, wait some hours, and replace, after boot battery is 100%
Sent from my JJ's Hybrid MT15i
I had this problem too, even when the mobile was off, the battery was drained...
I sent my phone to after sales service and now it's normal drain 2 - 3% per hour when idle. (I was on stock rom and kernel, never changed).
There is maybe a bad hardware series
Hello everyone, I'm using Motorola Atrix with Epinter CM10 4.1 ROM for last 2 months, I was very happy with battery life. Phone wasn't getting hot and with normal usage, even with 3G on (in my country only options are 2G and 3G), I could get %40 of battery end of the day. But for no reason, phone has started to get hot (only 2G on) and drains battery really quickly for last 1 week. I can't even get %5 battery left from morning to evening now. I didn't change anything, only installed Adobe Flash 11.1, then I deleted it but nothing has changed. Phone gets into deep sleep no problem with that, no background apps. I did a virus scan both on phone and from computer, both came out clean. I reinstalled rom. Nothing. I'm gonna crash my phone against wall it's really annoying. I think I'm gonna do factory wipe and reinstall rom again.
Any ideas? Thanks in advance.
Do you leave wifi switched on at all times?
I use MIUI on my Atrix (partially based on epinter's work, I believe? Correct me if I'm wrong), but I have found that the phone suddenly starts staying awake for no apparent reason a while (often a couple of days) after I've left wifi switched on. This obviously causes bad battery drain. I can usually get the phone to sleep again by rebooting with wifi switched off (I think) and a battery pull is invariably required.
I now just switch on wifi when I have large files to download then turn it off straight afterwards.
Not sure if it is the same issue or not, but Better Battery Stats (which can be downloaded on xda) indicated the Rilj process was stopping the phone from sleeping when this problem occurred. It is worth trying this app to see if it gives any indication what is causing your battery drain.

No I switch between mobile data and wifi. Thank you for your suggestions and opinions but I really don't think my problem is about sleep. It started to get hot and drain when I actually use the phone. For example, I was checking Twitter for 10 min. with 3G and battery was dropping %1. Now it drops %5 with 2G on and gets really hot like 35-37 Celsius degree. I'm using Watchdog to oversee processes and nothing is working without my knowledge on background.
Hi,
I have the same problem on the nottachtrix roms since the last 2 weeks, I tried switching to epinter cm10 with no luck. Ordered a new battery to check if the battery is dead or if the atrix is faulty
if you find a fix, please post it here

install gsam battery monitor to see your phone's awake time. this drain happens to me also when i listen to music or take a photo. something with mediaserver keeps the phone awake and then only thing to do is kill mediaserver or a reboot.
Regardless of which other apps you are using to monitor app and process usage, I'd recommend trying Better Battery Stats as this is much more detailed and low-level than other apps I've encountered.
It's a free download for xda members:

Little update.
I turned back to factory settings, then did a full wipe, cache wipe, dalvik wipe. I was so annoyed I even did system wipe manually from advanced options in recovery. I reinstalled Epinter CM10 rom, got my apps back thanks to Titanium Backup. Installed GSAM (thanks to saldirai), downloaded SetCpu and chose Nvidia Tegra 2 T20/AP20H, underclocked to 912 mhz. Couldn't done any undervolting sadly, says something about governor.
Now I'm checking battery stats and temperature by GSAM, so far no complaints and better from yesterday BUT I haven't use my phone heavily yet. Temperature changes between 26-31 Celsius degrees, battery drops %1-2 percent on use -also it needs calibration- with only wifi use which is always on. I'll update this post if anything changes.
Update: I think I've found the problem. When I choose The Weather Channel widget to "use my location" phone immediately starts to get warm. Weird point is, this wasn't an issue before. Apart from that I'm playing New Star Soccer and Carmageddon for 3-4 hours with wi-fi full time on and battery drops to %30. I'm really happy about that. Normal battery temperature is about 25-32 during the day and different from before it quickly gets cold after I stop playing games. Just like before.
Hello everyone.
Recently I acquired a Cube U9GTV tablet. When it comes to value for money, it's quite okay. However, I think that something drains its battery.
This is my first tablet so obviously I have no idea what to expect, but I have a Samsung I9000 running 4.2.2 and compared to it, tablet's battery is out of the league. My phone can stay up to 3 days being idle, taking no more than 1% per hour (of course without wifi/3g/gps, just cell signal). When it comes to my tablet, it can hardly last a day without charging, eating 2-4% of battery per hour. No wifi, no synchronization, no location access.
Maybe I just expect too much, but I some other users of this device report that their device can stay alive up to 3 days, while being completely idle. Mine cannot make it to a day.
Things I have done so far:
Clean ROM install, no Google account, no Synchronization, no Wifi, no BT
Deleted Phone.apk, TelephonyProvider.apk, MMS.apk -> the Mobile network signal bar in Battery status changed from red to yellow, battery drain decreased a bit
Disabled Media Scanning by Rescan Media Root
Stopped Google services running in the background (but didn't touch the cached ones)
My tablet enters Deep Sleep with no issues. But I noticed that the battery drop rate is not a constant, it varies and it seems that sometimes it drains the 1% per hour, but then something happens and hops to 4%/h.
The thing that concerns me is the Mobile network signal, which is completely useless cause my tablet is only a Wifi version, and I do not use external 3G modems.
I am unable to see battery usage in Settings, it just says it's unavailable. So I got myself Better Battery Stats, made a test and screenshotted results (see Attachments).
Why does it show No or Unknown Signal and No data connection at 100%?
If you have any suggestions or tips, share them with me please.
Thank you in advance.
Bumpety bump.
Don't punish me for spam!
I think we've ALL been here. Is there any uniform answer to this?
Let's be honest, I'm one of the not so frequent xda user, I always read several articles but have been, so far clueless.
I have the international model running on CM10 and constantly switch between ROMs of stock and CM, I've always liked AOSP ROMs, love the simple and uncluttered interface as opposed to the ever so bloated touchwiz. What else can I say? It has 32GB SD card and 16GB onboard storage, and it has a little trouble with 3rd party chargers (lose connection / disconnects every so often ) Its an old phone in technology time, but its still great.
So, I've tested wirh CM, stock and 2 other kernels which still make me feel like the phone is gobbling up a power plant everyday. One main culprit is Cell Standby which is very odd since it's usually just in my room (I use an other phone otg) and has a pretty decent signal (3-4bars)
On the most recent checks:
Cell Standby - 25%
Android OS- 18%
Screen - 15%
Google Services - 10%
Phone idle - 10%
Android System - 6%
And the rest are some of my apps..
I just recently started using Deep Sleep Battery Saver and wakelock detector. I'll send the info when the results are in for a day.
I'm not that fond of using 3G since data rates in my country are time-based and the KB-based pricing is off the charts. So I only use my phone for call and text and the occasional casual gaming and browsing (usually the cnet app)
I can only say that, if we could help on this either way, there are a ton of xda threads related to fast battery drain with varying issues because of Androids openness, I can only think if there would be some sort of centralized thread for this, or if you guys could help. That would be pretty awesome.
Ask any question or request anything so I could get this phone going. Thanks
Cell standby will be highest because you don't use your phone.
It's not a culprit,it is normal that it is up on the chart
But if you are experiencing any battery drain of more than 1-1.5% on standby then you have to look for an app or similar service running in background otherwise there is no problem
Press thanx if i helped you in anyway...
I don't think so. I left my phone's battery last night at 29% and after waking up 6-7 hours later, I got 16% left.
So that's around 13% consumed in one night without using it, or 2-3% drain per hour.
I already greenified Facebook and Lookout which were the biggest wakelocks, deep sleep gave me no noticeable difference even on Slumberer mode. I'm suspecting this is due to cell standby. the location which my phone was in had 3/4 bars of signal, wifi and location services are also turned off.
What's the big problem here really? I suspected it may be due to facebook but nothing has changed so far
Update: Signal strength is 73-80+ dBm, When I got home today the phone was dead from 16% this morning. The highest consumer is Cell Standby at 26%, Facebook is already turned off and everything, Still no perf difference.
So I also have a friend on and he's got a GS4, battery life was terrible for him since the kitkat update.
Anyone??
