This is a sister-thread to "Battery Drain Fix" for the g2x that lists a factory reset as a possible fix to battery drain issues.
First, let me say that even if you do not currently have battery drain issues with your G2X, that doesn't mean that you're immune. My battery has been phenomenal at times, abysmal at others. I've done the factory reset and that DID help for awhile, but battery problems arose again.
I believe the problem that plagued my phone was the dreaded 50% cell standby problem. If you're unaware of this problem, essentially the issue is that "cell standby" (found under settings --> about phone --> battery use) is at or around 50% always -- in other words, it doesn't matter that the phone has fine reception, is or is not being used, or even has the signal active (that's right, the problem persists even with airplane mode activated).
While I do recommend the factory reset method (assuming that you haven't had your phone too long, as it can be a real pain to reconfigure everything if you've set it up how you like it over many weeks...), I think this alternate method is something we should all do as well. In brief, you'll want to do the following:
-open dial pad and dial *#*#4636#*#* (If Testing menu doesn't come up than click "Call" and it will come up)
-Go to Phone information
-Scroll down and you'll see preferred network type
-click it and switch it to GSM/WCDMA auto
-click back button
After taking these steps, you should see an immediate improvement to your battery drain problems, as well as much faster battery charge times. Additionally, your cell standby % should decrease dramatically.
Isn't the same effect achievable from the Network Settings? No need to go to the secret menu. Unless I'm missing something.

I thought the samw but in the hidden menu it is set to wcdma preferred
switched will report tomorrow
thanx for this. hope it works

Interesting. I've had mine set to 2G networks only, so I hadn't noticed. I'll switch it over as well, and see what happens. I've been getting great battery life though, so this is purely an exercise in curiosity. Regardless, the root cause of this problem has already been determined- the drivers are ****ty. CyanogenMod is liable to fix this up immensely.
I changed mine too and I will report back if I notice any improvements

The battery reporting is terrible so cell standby could be nothing really.
I believe doing this also fixes the GsmTracker poll failure in one of the threads. At least mine is no longer red but green (in the logs)
I can personally attest to the fact that this does absolutely nothing different. I have had my phone switched between WCDMA, GSM and WCDMA/GSM auto just to see if there was any difference for the past few days. My device has battery life worse than the HTC Thunderbolt that I returned, and being only 7 days in I'm thinking about doing the same to this device. I'm definitely experiencing buyers remorse.
@TheMightiest -- did you do a factory reset first and then try this method?

I've factory reset my device 5 times, just drained it, for the 5th time and recharging it as we speak. I still lose between 15-30% per hour if data is enabled...just like the HTC Thunderbolt. At least I got 19mb download with the Thunderbolt, I'm getting an average of 6mb with the G2x, which ain't bad, i'm just saying.
Mine was set on gsm only. I've just made the switch so i'll report back if there is a difference or not.
I've read a lot on the whole philosophy of "drain completely and recharge fully to maximize battery life," and from the looks of it, that method doesn't do anything for Lithium-Ion batteries, which have no memory effect (http://en.wikipedia.org/wiki/Lithium-ion_battery - not that wikipedia is the ultimate authority on things, but hey, it's a link at least).
Your battery sounds WAY worse than others' batteries...you should seriously consider returning it and getting a new one.
Well, my cell standby percentage has not gone down at all, but still my battery consumption is much improved.
As was stated in this thread, the battery readings may be very off the mark from actual battery life, however, that fact doesn't help explain why some of us only were getting 5-6 hours of battery life with moderate (and sometimes no) use. There obviously is a problem, and CM7 may well fix it, but the method in this thread has definitely helped my phone stay on longer...irrespective of battery readings.

This is not the reason people on these forums recommend draining completely and charging fully. The reason is that in order for your phone to get a semi-accurate idea of what percentage the remaining battery life is at. With this particular phone, however this is probably still a lost cause as the driver will never give an accurate approximation of remaining life.
At any rate, the full drain, full charge is a one time thing. This will also in no way extend battery life (but I haven't seen anyone on the forums claim this either). You can, however, extend battery life by keeping the charge at ~80% and keeping it as cool as possible.
On a side note, great to see yet ANOTHER battery thread

It's amazing right - we have dual core 1Ghz processors in our smartphones with 1GB of RAM and high res screens, 4G data, etc. etc. yet battery technology hasn't advanced in years. Whoever improves battery tech is going to be the richest person in the world. Think about it.
Edit: Btw, mine was set to WCDMA preferred although in Network Settings it was on Auto so I changed it to Auto.

Okay. I read the original thread and it sounds like the 50% is refering to the "Time Without Signal" value when you actually click on Cell Standby. Not the value of Cell Standby itself.
My G1 running FroYo last month had at least 50% Cell Standby with only ~1% Time Without Signal and the battery lasted about 2.5 days with moderate use.
I'm not an EE so obviously, I could be wrong about this.
You sir have just received a thanks, because this could also be the cause of some of our data issues and how the phone picks up on 3G vs 4G signal. Im doing some testing regarding APN and now with this hidden menu. Have noticed my speeds are a little bit better then they were. Battery drain was not a problem for me before.
Thank you! i did this to mine and my husbands g2x's last night. seems to have fixed the switching issue
I heard good reviews about battery life of Moto G but mine's battery life is disappointing, could you please see my stats and tell me if its normal or something is wrong.
There can be many factors why battery life is that worse. Bad programmed apps, Wifi always on, screen time, call duration, running background processes and so on. Most times i switch my data connection off if i don't need it. I run my phone since 2 days and 8 hours and my battery is on 9% at the moment. As i see your wifi was always on. Try switching it off.

Screen on time is around 4 hours, I haven't called even for a second or used my data connection yet, but I keep wifi always on because I thought it causes lesser battery drain.
How can always wifi on cause lesser battery drain?
Don't know, sounds unlogical to me.
4 hours screen on? Phuu........did not try it but i guess it is normal if you have your screen 4 hours on.
What are you expecting? Switching everyting on and then have a two days battery life?
See yourself on your graph how battery got better when screen was off. Now switch off wifi and try again.
In my opinion i don't see any problem with your phone.
Maybe someone might correct me if someone feels that i am .....

I thought Wifi uses lesser battery than 3G and I expected 20 hours battery atleast.
I see your Wifi is working all the time. Are you aware of this?
In some JB Android version google implemented automatic Wifi networks scanning (probably for their purposes), even when Wifi switch swhows "disabled".
You can disable it, maybe it can save some battery: http://www.pcmag.com/article2/0,2817,2422689,00.asp
Cheers.
Install BetterBatteryStats and see if there's any wakelocks that are eating your battery at the moment.
Also, about your on screen time - what's the settings for brightness that you use? You might want to consider dropping the "auto" and go for a reasonable low level of brightness that fits your indoor or outdoor activities.
Your assumption of WiFi eating less batter than data connection is correct in most of the cases.
Anyway, if you have any doubts about this... an average NOTE3 user can't get to those 3h 30minutes with on screen time

Your battery is normal with so much screen on time.
It does look disappointing,i get a lot more than that but mine is rooted and greenified and set up how i like it.
Im currently on 1d 18h and have 39% left with 4 hour screen time and that's with a mixture of wifi and 3G.
i enable airplane mode overnight though which only uses 1% in 8 hours.
I'd say that's normal battery life for this phone here's mine for today.
I'd agree with the previous post.
I've been on a WiFi network for the past 7 hours.

Motorola is advertising this phone as all day battery phone so shouldn't it last more than 12/14 hours.
A car manufacturer also advertises his car with 500 km per full fuel tank. But if you drive all the time with 170 km/h per hour over the highway then this statement can also not be applyed anymore. As i said, i switch on wifi only when i need it and thats the same with data. I had a battery life for nearly 72 hours. Ok i made also less calls in that time. But it is all about your usage. I for my opinion can not find any problem as i said already. Motorola advertised nowhere that you can use your phone under "full load" for a whole day. This is called marketing in todays world. If you be believe everything what advertisement says then you seem for me very naive....... you should think about that

Atleast the reviews said it last more than a day and I didn't used the phone under full load, just the Wifi was on all the time which uses lesser battery than 3G and I did 0 calls.
It might be true that 3G uses lesser than WI-FI, but what is that for a comparison? You can not compare WIFI and 3G because it is a completly different technology for different purposes. 3G Data uses a lot of Battery that's true. But WIFI also but less than 3G. But this statement doesn't mean that WiFi uses nearly no Battery. It uses only less. If 3G uses 100 parts energy and WiFi uses 85 parts energy out of 100 then it is less. But 85 is still a lot out of hundred. I quoted full load, just as a general statement. I know you had not switched on Bluetooth and so on. But anyway, Dataconnections are a expensive feature in relation to battery life.
Did your review tell you the exact conditions they tested it under? Or did they just say that without any proove? Also Tests and reviews are often copy and paste bull****. If i see an Antivirus test and the Userinterface is tested bad but the userinterface has a 45% weight in the all over test then i would say this is a crap test.

Yes see the gsmarena battery test I've attached, my phone doesn't even come near to its battery life
Unfortunately I can't take a screenshot but I have a stock (not rooted) Moto G that loses excessive amounts of battery with Aeroplane mode on!
What can possibly be causing such excessive battery drain - 50% -> 7% in 6 hours with no screen on or data or wifi.
Thanks

Hi that's a lot of drain i'd say theres some rogue process that runs even in airplane mode with no internet killing the battery i'll attach a screenshot of mine from last night this is with network on but WiFi and data off.
Has anyone else experienced any issues like this? Over the past week my Nexus 5 has been going through about 60% battery over night. In the past I would at most use 5-7%. I posted a couple pictures of my battery usage. I live in an area where my signal is always LTE and usually 1-3 bars. I do not have any new apps, location, gps and pretty much all google services SHOULD be off...

If you tap on the graph itself you'll be able to see if the phone was awake frequently or if it was losing signal, etc...
If you're seeing that the phone was awake often, try BetterBatteryStats to see what is keeping your phone awake.
Wakelock Detector is another app to try and pin down the problem.
Also, maybe try wifi overnight instead of LTE to see if that might be the issue.
its your signal quality killing your battery. you have phone idle and cell standby taking most your battery.

What is especially strange is it appears you're on WiFi, and yet both the voice and data connection seem to be causing the largest drain here.
Tap the graph so we can get an idea of what the awake times and signal strength was like.
I have a similar gripe and I pinned mine down to stupid photos uploading overnight via wifi and a bunch of other wifi related crap....pretty much network things causing battery drain. also the auto update's killing it for google play stuff.
I found that switching to dalvik and back to ART [which i was on] helped a bit though i supposed there's a process running somewhere in the background that's buggy...here's hoping 4.4.x fixes it
Switch to ART cleared it for me

I also saw the same. Turning off functions, etc. had no effect, but switching form Dalvik to ART did. I'm guessing that the change probably cleared something in the OS that was actually causing the problem. Note that the reported sources of battery usage are almost the same in both images, even though battery usage rate is vastly different.
I've attached two screen shots before and after the runtime switch. The red arrow on the before image is when I made the runtime change.

This is a shot from last night. I went to bed with about 50% battery life and woke up with a dead phone. Looks like cell signal maybe...
I am already using ART, but maybe I should switch back to dalvik and back to art like someone suggested earlier.
I've noticed more battery drain as well as reduced cell signal. My phone is losing connection in areas where I'd previously have 1-2 bars. I was thinking T-Mobile was changing things on their towers, but I'm starting to see other Nexus 5 owners complaining about it as well. Did they update something in the background on our phones?
You REALLY need to get Gsam and take some screens from it after a night. The stock battery usage screen shots say very little of use.
Otherwise we're are all just guessing here.

It's worth a shot, and I, for one, am curious to see if it helps.
FWIW, I just noticed that my battery usage is increasing significantly again. So, I may try the same thing if it persists.
I'd say there is definitely a bug somewhere, possibly interacting with an app or a subset of apps. Are you using Tasker, by any chance?

As I noted in my previous post, my phone started chewing battery again yesterday. No evident trigger, battery usage rate just went up abruptly. I recharged the phone and then left it asleep over night. Images below captured this morning.

Obvious culprits are WiFi and radio. Check in gsam (might be too late if you charged) for kernel Wakelocks. Or try wakelock detector app.
You could have a WiFi issue caused by other devices on your network. Would have to search on that for causes and cures. I'm not sure. I only know its been an issue.
And you appear to have no radio signal at all. If you go in to radio screen from main gsam screen, it will tell you your time searching for signal. That can destroy battery life.
It doesn't seem to he an app. Or general held awake time...as you have hardly any.
Putting phone in airplane mode over night would prove its WiFi or radio.
---------- Post added at 09:44 AM ---------- Previous post was at 09:41 AM ----------
If a night of airplane mode is no better, then its a rogue app. That you'd need to track down. Process of elimination style.
But its probably either WiFi or radio signal. I guess if you have location service on, it could be adding to the trouble.
Turning off WiFi would show if its WiFi....or radio. But with very poor radio signal....I know you're battery will take a beating anyway.

What's puzzling to me is that it was not an issue until a week ago, then converting to ART made it go away temporarily.
My radio signal is poor, but it's always that way at home. I definitely plan to see what airplane mode does. Will report results.
Thanks for your help.

These images are from last night. I went to sleep with about 55 percent and woke up with 31%. The screenies are from betterbatterystats. Maybe you guys see something...
Definitely radio in my case
kj2112, you were right on. :good:
Running in airplane mode removes all serious battery drain on my Nexus 5. If I turn WIFI on, there is only minor battery usage. I've installed OpenSignal and will try monitoring radio reception vs. battery drain.
I'm still puzzled by the sudden onset (could be a problem with my nearest tower, I suppose), and the fact that switching from Dalvik to ART dramatically improved battery life for a few days. That's hard to link to the poor cell signal.
I'm still suspicious that there is a software component, that may or may not be interacting with my cell signal strength.
Follup up / more info
Based on posts on other forums, I tried excluding LTE from my preferred network types, and my battery usage improved dramatically. If I choose 3G, signal strength is 2-3 bars. 2G gives me 4-5 bars. With LTE I get 0-1 bars - mostly 0. On 2G my battery life is the best I've ever seen
My suspicion is that the sudden change I saw was caused by a change in the way the radio software selects network speed options. It appears that if the preferred network type selected is LTE, the phone now will expend maximum effort continually to connect to LTE, even if there is no useful signal available. Before the change, it's likely that a stronger LTE signal was required before the phone would attempt a connection.
I'm not sure if the OS determines where that set point is located or if it's something the carrier can control. If it's the carrier then maybe the Nexus 5 has a radio that isn't as efficient as other phones, and the current algorithm is pegged to the best case phone.
If anyone knows how to adjust the conditions for attempting to connect to LTE or has any ides about who does control it, I'd definitely like to know. For now, I set my phone to 2G or 3G when I'm in a poor LTE reception area (which with T-Mobile is most of the time). That actually works okay for me, but I doubt it's a solution for everyone.
Anyone else experiencing this? Atrocious battery life post upgrade. Nothing odd running in background, program or processes. Rebooted phone. Started the day at 100% with moderate usage at best, I'm already down to 19%.
Battery life is relatively unchanged in mine after the mm update. Easily make it through the entire day with 50-60% battery life remaining. I disabled a whole bunch of the bloatware (and will be removing it entirely when I decide to root my phone) and battery life is wonderful.

Mine has been fine, slightly better with doze/disabling packages. Do a back up through Smart Switch and try a factory reset. I do that every time I update.
I'm envious of your successes. I'll give it a bit to see if it stabilizes, if not I'll use SS and reset/restore.

I will recommend "Package Disabler Pro" to disable bloatware. Costs but is worth the cash.
Mine went through on Thursday and so far battery appears ok.
I have noticed however the lighting is messed up all over. Play books night light feature is broken and dims it to unrecognizable levels. I have to go into the settings again when in the book and disable auto lighting and manually raise it. When back at the list of books screen, the brightness drops to nearly off again.
Also it seems the notifications when listening to music are much louder. I could listen to mp3s via poweramp while reading a book and get an SMS text and itd be a light little sound. this is playing louder than my music and very annoying.
My batter life was horrible after the upgrade. Here's what I did to fix it.
1) Wifi sleep policy - Changed that to "While Charging" (big difference noticed after that)
2) Fully charged phone then let it run down to 0 (must let it power itself off)
3) Wifi Scanning has been moved under Location setting. Go to Location -> Improve accuracy, make sure Wi-Fi scanning is off.
Batter life is awesome now.

1: Apps/sync will use mobile data as priority if this is done while waiting to connect to wifi. In turn, using even more battery if an app/sync wakes the phone switching between networks.
2: This is damaging to Li batteries. To extend the life of your battery, it is better to keep it topped above 80% and cool(not very common in real world applications). These aren't Ni batteries, long gone are the days of "memory discharging".
If you don't need notifications at night, use airplane mode. I miss Xposed, Autotasker, and Amplify(formerly Bounce)... Greenify is a good alt atm
Note: Sometimes even Play service updates will introduce bugs and or "retarded" policies that will destroy the battery, especially the "Now" systems. It can happen at the most random times as well and not at all most. Every now and then the fat man will get stuck in the tube.
All thoughtful replies. I don't have Location on ever, unless I'm using Waze, so that's a non-issue for me. Allowing WiFi to sleep when the phone is off, while I'm only connecting via WiFi, effectively makes my smartphone a dumb phone, until I wake it up, right? The fact that I need to start changing around "normal" settings on my phone, to lesser benefiting ones, to get back to the battery life I had before I installed MM is pretty silly. I've been hoping things would settle down, but they don't. I can try using SmartSwitch later to see if that helps.

No, it will connect LTE and then switch to wifi. LTE use more battery life, the network switch uses a bit, then finally you are into wifi. If your phone wakelocks or alarms(location ping, play service ping, etc) it will use more battery than wifi always on. Personally, I've tested both to make sure a wifi wakelock bug hasn't been introduced as I do with every update and play service update(it does happen and it's horrible drain). I see more savings always on.
If you meant you disable mobile network, yes, dumb phone, text and call. Also, I disable mobile usually always as I piggyback off work cell at work, and always wifi at home. I only toggle mobile data when necessary.

My batter life was horrible after the upgrade. Here's what I did to fix it.
1) Wifi sleep policy - Changed that to "While Charging" (big difference noticed after that)
2) Fully charged phone then let it run down to 0 (must let it power itself off)
3) Wifi Scanning has been moved under Location setting. Go to Location -> Improve accuracy, make sure Wi-Fi scanning is off.
Batter life is awesome now.

I believe this is what most people encounter. Most dont have unlimited data and use WIFI always. I think by default, WIFI is set to always on, even when phone screen is off. WIFI will rape your battery. I did my own tests with wifi vs 4g and just by using my 4g all the time, battery quadrupled. Many argued that WIFI uses less battery, and i have the best of the best wifi router/modem/isp with 5ghz ac excellent coverage. Not the case for me. I have unlimited and just stick with that now. Battery life on MM has been great for me.
My battery life is 4x better. I couldn't be happier.

Anyone else experiencing this? Atrocious battery life post upgrade. Nothing odd running in background, program or processes. Rebooted phone. Started the day at 100% with moderate usage at best, I'm already down to 19%.

Been on MM for about five days now and my battery blows, so much worse than what it was!

Mine is exactly 4 times worse
Battery the same.
But I have to tap the screen harder to chose app.
Going to factory reset and start clean, been a while.

Not that I know of.
Though they JUST released Marshmallow. Verizon is probably still patting themselves on the back even though they released several months late. What I'm waiting for is a miraculous root.
I never use my phone the same amount every day, so it's hard to say exactly what kind of battery life I get, but I have noticed that it has improved. I would usually be near 15% by 10pm after coming off charger at 6am. Now I float around 25% at 10pm. So it seems to be better, even if only slightly so.
I see a minimal improvement, but I was doing what I could without root prior to sleep unnecessary crap.
Weird, when thye MM updated happened, up until the last two days, I was getting much better battery life under MM. But the past few days my battery life has declined dramatically to the point that I am not getting through a day of minimal use. Screen only 2%, Android OS consuming 76%.
I just fiddled with settings (Changed Wifi sleep to While Charging; Turned off wifi scanning). I am going to also try a reboot to see if that helps. I swear it started just about the time I started looking at Nexus 6p replacements).
Update, rebooting, and removing a few more useless apps and battery life has returned.
Hello,
I recently picked up a OP6 and I'm really pleased with it overall but SOT has been a little disappointing. At least I think it has depending which battery app I consult!
Accubattery Pro thinks I'm getting an average 8h 16m of SOT (this is definitely not correct!).
GSM Battery Monitor PRO reckons 4h 46m of SOT (which still seems a bit high).
In the battery tab of the Settings menu it reckons having used 65% of my battery I've had 2h 50m SOT (ie. from 100% after 2hr 50m of SOT I'm now sitting on 35%). I think this equates to about 4h 30m of SOT if I continued at the same pace. I guess this tallies pretty closely to the GSM Battery Monitor PRO so maybe this is about accurate.
I've followed the guide here to get the most SOT but 4h 30m seems on the low given that I don't game or stream, don't have FB installed etc. This is purely webbrowsing, a bit of YT and a podcast app (listening to downloaded podcasts rather than streamed if that makes a difference).
Nothing in the battery stats seems that unusual (please see attached). What does seem a little odd is that I'm not in a great spot for mobile reception but looking at the stats it doesn't look like the radio is draining the battery.
Any advice on how to delve deeper? I'm 100% stock and not rooted.
Any advice for a OP newbie is much appreciated
Hmmmm Better Battery Stats seems to tell a rather different story especially around the radio reception.
Again any advice much appreciated!
The poor signal is killing you. When the signal is poor it pumps out more juice trying to stay connected. If you will be in an area with poor signal and won't be using your phone I suggest putting it in airplane mode or maybe setting it to 3G as a proof of concept. If your battery is much better then you found your issue
Also wifi scanning is turned on,which is a battery killer. Turn it off and you can see a great difference

Thanks Spartan! The problem is poor indoor reception with the signal constantly cutting in and out. As such airplane mode may be the ultimate option but obviously it's a bit of a bummer as a long term solution! I'm going to try another provider which claims to have better indoor coverage in my area.
Question #1 - you mention trying setting to 3G as a proof of concept. Is that because a 2G/3G uses less power to connect than searching for a 4G connection? Should I try the 2G only option before the 3G one?
Question #2 - if I do try 2G/3G (before trying airplane mode) should I turn off mobile data too or does that make a difference?
Question #3 - I'm guessing having 2 sims installed makes the problem even worse as both are constantly calling for signal? I typically use one for data and one for voice.
Question #4 - when some folks post their battery graphs they have a picture which shows the mobile and wifi signal (see attached as an example). I don't seem to be able to find this. Was it removed from the latest update as the battery section seems to have changed a bit.
Thanks again!

Thanks for taking the time to reply!
Strangely I don't think I do have wifi scanning on (please see attached screenshots)! Location services are also off.
Are you thinking I do because the wifi is on 100% of the time?
Could this be because an app is somehow keeping it awake?
Hmmm can't see an option to check if "keep wifi on during sleep" is enabled. Has this been removed from 9.0.2?
