Hello all,
I have confirmed the following issue on my Optimus 2x with stock 20L. Nothing else, nothing special.
When I leave the phone standby for several hours (eg. during the night), when I get back to it and turn on the screen, the network signal/3G indicators are white - meaning no internet connection.
After around 10 seconds, 3G reconnects itself.
While this is annoying, since you don't get any notifications from programs using the internet (WhatsApp, Facebook etc), it gets worse.
After 3G reconnects itself, the battery drains really fast: about 30 seconds for 1%. So in a few minutes your battery will be completely drained.
This even continues while rebooting.
For example: I come back to my phone and it has 46% left. Then I notice the 3G disconneced and reconnecting and then power starts dropping really fast. I reboot at 43% power left. After the reboot, there's only 18% left but the draining has stopped.
I at least had this happen twice in four days.
Is anyone else noticing this, or does any of the developers out here perhaps has a fix or a custom rom in which it is fixed?
I really like 20L for some new features, but I'm also experiencing issues with GPS and now also this... I'm really thinking of going back to 10D.
Thanks for any help or insights you can give me.

I also have huge battery drain, but in my case the main culprit is OnScreen Phone. Left my phone with 100% in the evening and in the morning, after exactly 8h, the battery was at 70%. Of that, 50% was used by OSP, and 25% each Idle and Cell standby. With the phone on wireless, froyo used at most 10% instead of the 30% used by GB now.
Yes you should remove all background running apps, especially the sh..y LG one Phone on Screen, but also checking for others, like media share programs and so on.
One time with my present ROM I had a storm in my battery with tremendous drain.. I had to do a fresh reinstall, and since then no problem.
Thanks for your replies, but this is different.
The battery only starts draining when 3G reconnects and you can literally see it happen.

Same happening here. I'm running on topogigi 2.0 SP3.
With Baseband 725 I'm having this issue. Now I'm on 622 will see tomorrow what happens
Edit: I'm noticing, that even if I have full signal with an "H" the phone starts switching from H to 3G and back when I turn the screen on
I think I can confirm that huge battery drain on GB is because of the radio. The reporting of huge consumption by OnScreen Phone or Gallery may be wrong.
I left last evening my phone fully charged on Flight Mode and after 8:30 it consumed a mere 1-2%. With Flight mode off GB uses like 30% and Froyo used 10%. So I suppose the radio is the main culprit. As you can see in my screenshots, the Gallery process is said to have used the most energy, but it wasn't even started. And some days ago OSP was in place of Gallery. In the third screenshot you can notice how the drain started when I turned off the Flight mode and browsed for 45 min or so.
Could it be that we're experiencing this huge radio drain because of the incorrect baseband? I suppose we all have the generic Euro Open/Italian v20L ROM, and maybe our networks need a correct baseband for our specific operator?

The first time i experienced the battery drain problem i had no rooted phone with official Gingerbread update from LG. That was last week. The Baseband was exactly the same as from Froyo 10D (725).
With Froyo I had no battery drain at all. So LG must have messed something up - that was my thought...
since then i rooted my phone and installed topogigis rom on fr, 4th nov. At the weekend i was in areas where the signal strength was very good (H in status bar).
On monday no battery drain on my place of work where signal is very bad (G in status bar).
Since tuesday battery drain is back. I get reconnects after reconnects when the signal is weak. Even when the signal is very good my phone jumps from H to 3G and back. What the hell is that?
You need to flash the GB baseband released with the rom, the 0725 basebands are not the same. Flash the 0725 baseband in the v20l thread of Hell_97 and try again. Without it there are many issues.
Sent from my LG-P990 using XDA App
Maybe I was a little uncertain:
- Last Wednesday (2nd nov) I had an unrooted phone with froyo. In the morning I checked for an update with LG Software and boom I had Gingerbread.
- Until friday I had heavy battery drain (9h and battery was at 5%). I was so angry and thought f*** you LG-Guys I'm flahing topogigi's rom. I flashed the Baseband 725 from his thread. On Saturday to Monday evening no problems at all.
- On Tuesday my phone again had very bad signal an it was often active (in the Battery-Usage Menu were much of those blue bars.
- Yesterday I flashed 625 Baseband -> problem not solved
- today I flashed 502 (from LG U660 10S update). I will look how it works.
What I noticed on all Gingerbread roms is, that the phone often Disconnects an Reconnects. I think that's making the heavy battery-darin.
But I have no idea how to fix that...

If you have updated through LG update tool, your Baseband had been updated to last (=the one recommended for Hell ROM), and above all the one recommended by LG for your area...
I think you should put back this one...

I've read many threads about this issue, but couldn't find a solution for Optimus 2X because on our phone, the PDP Settings in the HiddenMenu aren't implemented yet, so we can't disable Fast Dormancy.
I've found a workaround when you're at home: you can change the WiFi policy to never sleep, so during the night, the phone will use WiFi only instead of 3G while it's sleeping. But still, this doesn't hep you at all when you have no WiFi available.
I called LG this morning and they sad I'm the first reporting this problem (huge 3G battery drain on newly released Gingerbread)
Has anybody found another solution?
So I've been testing CM9 for quite a while now and can't help notice the battery life has been reduced heavily compared to Honeycomb 3.x.
Now, I don't mind that my battery life gets a bit shorter as ICS brings more features and might be more power hungry. But I went from my tab being able to hold a charge in standby mode in 3 weeks to barely 3 days. And if I use it more heavily, it barely holds a day, which is worse than my Motorola Atrix and that's just not normal.
Now, I've been discussing this with pershoot and for him it must coming from something I do. Honestly I don't see what. In the Honeycomb days, I used to have so many apps installed (may 100-150) and battery life was fine. In CM9, I'm running 50 apps, the essential ones. All the apps that could be power hungry have those settings set to off. No push notifications, very large updates intervals (a day) or none when possible. Also, I run most on these apps on my Atrix (which has more apps installed) and my battery life is way better on the Atrix.
In usage itself, I don't see any change, it seems the tab consumes the same amount of battery than before. It's the sleeping battery life that is terrible. In my case, in sleep mode, wifi is off, brightness is set to Auto and data is off (not the signal itself but I tried to take off the SIM and the battery life is the same).
Honestly, not having to care about charging every day is a must feature for a tablet.
I'm running now RS125 ICS, based on stock and the issue is also there. So I wouldn't say it's something related to CM9 but more on how ICS behaves with our tab.
I've read report of other people complaining (with the 10.1 also) so I wonder if it's a general issue. Could you please fill the poll so we can see if there's an issue and if so, how could we identify it ?
Don't hesitate to describe your tab usage and battery life !
Thanks !
For me worsts battery life was with the official 3.0.1. 3.1 was big improvement. 3.2 and 4.x were a little bit better than 3.1.
Got gmail and exchange push notifications turned on, but most of the time the tab is connected to the wi-fi, not to the 3G network
Attached is my personal stand-by record on the 10.1v. I think it was with one of the first pershoot's CM9 roms
Hi Danny,
Same for me. Especially the standby mode I see a battery drain.
By the way, somehow my battery usage is not working since I moved to the official ICS ...
Cheers
No problem @all. Stock 4.0.4 with OC kernel.. Looks like this:
GT-P7500 [email protected]
Kernel info...
GT-P7500 [email protected]
I have a really strange problem on my Note.
Whenever I open the browser and open two tabs (eg. Facebook and GSMArena), the screen starts flickering (this flickering also happens in normal usage when battery is at 1%). Along with the flickering, the network connectivity, both cellular and 2G is lost. After about 10 seconds of flickering, the phone turns off. On manually restarting, the battery level is at 1% (from whatever current %). However, on keeping the phone idle, it gains charge automatically.
Except this issue, the phone works perfectly on 2G data with background data on and all apps working properly. It is just the browser that triggers this issue.
I have tried
- different ROMs (Stock GB, stock ICS, RocketMIUI)
- different kernels (Stock GB, Stock ICS, Philz kernel, HydraCore) and
- different modems (LC1 and LR9)
and yet the issue remains.
Please help!
at <5% of battery power, the flickering happens and the phone turns off.. & this is happening to you at any battery % which is very unusual. have you tried a different battery on your note
Yeah. I know it happens on low battery. But yes, I have had drops from 68% and 46% to 1% because of the automatic shut down
u should definitely try a diff battery
My battery has bulged and spins freely on glass.. So I think it is a battery problem.
But Entropy has suggested something here in the i777 thread. Will this be of any help here? Here's the link. http://forum.xda-developers.com/showthread.php?t=1428989
interesting thread but if u see a battery damage.. then i suggest atleast try a new one before u start entering into coding
Hello everyone, there are many, many threads for our phone, so it is basically impossible to properly search and see if this question has been asked before and so here it goes.
I've tried many roms for my device (I call it Sir Hangsalot), and I have noticed that on almost every rom there is a huge issue for my device to keep itself in a deep sleep state when the WiFi is on. The ratio is approximately 70/30% awake vs. deep sleep (I am talking when the screen is off and the phone is not being used). Then I have tested with the WiFi off (mobile data still on, it is always on since I have an unlimited data plan) and the phone enters deep sleep as usual, but this time it stays in deep sleep and battery is discharging properly. From the moment I switch on the WiFi the same behaviour emerges again. This is the last night's situation. New battery (1 month old, 1700 mAh), fully charged at 1 AM, at 7 AM 54% left with the WiFi on. The night before, same conditions, WiFi off and mobile data on, at 7 AM 91% left.
So, my question is: what the hell is wrong with our WiFi which is causing this huge battery drain and is there a fix (rom, kernel, module, script, anything)?
Regards.

Sorry for late reply.
Go to Settings > Wifi > Advanced settings and uncheck the box "Network notification" ( Notify me when an open network is available) in wifi settings, also uncheck "Scanning always available" .
Use Greenify app to freeze apps ( apps frozen will stay closed until you open them again).
These should reduce battery draining.
Thanks for the reply. I always turn off those things in wifi advanced settings, and regarding greenify I am not sure that it will help since I have this issue in every rom, even in a barebone rom without installing any app or gapps. I thought that maybe google play services could be the culprit here, but even without gapps I have a severe battery drain when wifi is on. When using mobile data everything is just fine. I really cannot find an answer for this.

Stock jb bloated should also drain much battery when there is a network connection.
I don't have more ideas... But why you keep wifi on overnight? Do you have facebook app/ what'sapp / viber / etc. ? These drain battery alot, that's why you need to greenify them.
And why you use wifi since you have unlimited data plan?
To be honest, my battery drain too when i have wifi on, but not so much. In this evening, i will put my wifi on and i will let you know how much battery i have left tomorrow.
It will be interesting to see your results, thanks. I do indeed have WhatsApp installed (after setting up my device completely) but the behaviour is the same regardless, even after fresh install and no other than the core system apps (stock, cm 10, 11, 12, aosp, carbon, vanir, LS, tried them all). Regarding leaving wifi on all the time it is the matter of habit. Since I've been using an android phone from the start (from cupcake on Huawei U8220 to lollipop on a few devices) and I have never had this kind of problem. Oh, well, I will try to keep it off and turn it on only when I need faster internet speed (my data plan is unlimited but it does not have download speed as my wifi).
Cheers!

I tested two days. Wifi drain battery 15-20% for me. Hmm, maybe i have some wakelocks, not sure. I will check and i will let you know if i can solve this problem.
For sometimes MI 5 battery was acting a bit weird time to time.
Clean flashing to LOS seemed to solve the battery issue, but I discovered another issue while checking up with ampere.
When wifi is on, battery drain is abnormally high. (-870 ma on average in ampere). Even in idle time, there can be 20-30% drain when the phone is virtually nothing. And in addition to that, the heating was a bit high too, with wifi on.
I tried everything I could to solve these. Tested different roms (Xiaomi.eu, LOS, RR, Paranoid), firmwares, tried wavelock blocking and all that.
Of course, I tested the battery drain on a fresh rom - and the issue persisted. So it's not some rouge 3rd party app, unless one of the Gapps is the culprit. But, of course, I even tried disabling some of the gapps like gp service and play store, just to be sure. Yes, the problem exists even with synch and location off, and those wifi scanning and other settings doesn't do anything either.
However, with wifi off, battery was quite good (-100 ma drain on average in ampere)
Recently the issue started escalating. Not only was there the abnormal high drain with wifi on, but toggling wifi crashed the device and started a reboot, after which the device connected.
The only major thing I had remaining to be done - is fastboot. I did even that. Fastbooted into official roms, older 6.0 Xiaomi.eu roms which worked fine in the past ....but the issue persisted. In fact it started to escalate further. More reboots when I try to switch on wifi. Sometimes got stuck in a reboot loop ...and so on.
Right now, wifi is not even connecting. It just stays at 'saved'. Oddly enough, enabling bluetooth and trying to reconnect seems to allow the connection to take place. The drain is still here. (The solutions in this thread: https://forum.xda-developers.com/mi-5/help/wifi-connectivity-problem-t3517777 isn't helping me either)
I don't think this is a router issue either. I did tweak router settings, channels, and all that. I rebooted it and all. No help. And, other devices are working fine with the same router. But, the most definitive evidence that it's not a router problem is that I faced the same issues when trying to connect (with wifi) to a hotspot created from a mobile network from another device.
Do you think it's the worst case scenario: a hardware malfunction?

Could you provide battery apps and hardware usage stats and graph?
My prediction it caused by Google location service that try to lock location but was unable to get GPS lock, so it tried to used WIFI scanning to get location lock.

I can provide the stats later. My device has been offline (normal condition) for quite a while...so there's not much stat to share as of now. I will collect and share them later.
However, I have checked them before. There wasn't anything too interesting. The graph very vividly showed how it fell only when wifi is on...but other than that, most battery was taken by device, idle state or something like that. I didn't find anything interesting in betterbatterystats either. Other than that I did checked the frequencies with kernel auditor too. It seemed normal overall. Though once, I did notice high spike in CPU usage. IIRC, the phone was in deep sleep for most of the time too. Not sure, what the current state is, because new issues are coming up now. So I have to recheck the condition.
I always keep wifi scanning, bluetooth scanning off anyway. So that's not the issue. 'I will again check in the china rom (no gapps), this time more rigorously,....that should clear gapps out of suspicion, if they are innocent.

Check the screenshot
In a freshly fastbooted MIUI global stable rom (with wifi scanning off, and wifi always on off), I got 1% battery drain (100% -> 99%) overnight (6 hours approx)
But, only in a few minutes battery went down to 91% when wifi was on.
The device was idle in both cases.
In past I have assured that it was in deep sleep. Similar rate drain in chinese rom (so no rouge Gapps), and same drain in custom roms.
The hardware usage was taken after I used the device for a while, which is why drain due to screen on is high. Anyway, even before using the device, the maximum drainage was attributed to 'idle phone' so there isn't really any interesting info. One thing to note, that the hardware battery drain states doesn't consider wifi to be the cause of high drain, however the drain is still clearly correlated with active wifi.
