Hello , XDA forums , I am new here.:d. Recently , I think about a week ago I bought a new android phone , a L9 P760. The last 2 days the battery started discharging quickly, I got a battery app and it shows me that when the phone shows 100% charged it is 1500 charged. This phone has a 2150mah battery. What could the problem be?
I had the same, adjust brightness in ur settings i have on 50 percent. Or hold down home button and close some apps.
Maybe it helps.

Already did that, screen is at 25% , played World of Goo for 20 minutes and the battery went down from 40% to 15%. Yesterday when I went to sleep I had 50% and in the morning I had 45%. Forgot to say , I charged my phone for 12 hours 3 times , could that be the problem?
I think I might know the issue. Do you have a Bluetooth headset paired to the phone? My P769 seems to sometimes keep the link open between my headset and the phone. I know this because I hear a slight hissing noise in my Bluetooth earpiece from time to time. Even when the phone is idle.

Uninstall app
Try uninstalling app or try back up and reset the phone only then we can know whether its software or hardware
I have same problem. Charged device at the evening. Played angry birds for 20mins (battery was at 60-80%) then went sleep, and phone discharged, even turned off during the night, with no use, in idle. Checked battery consumption and it said Android operating system had 60% battery consumption, even more than display.
Device is pretty much new, I have there like 4 applications, wifi, bluetooth, 3G turned off. So where might be problem ? Thanks.
/edit: Done some research, for Rassva - battery application shows 1500mAh because its set to 1500, application doesnt know capacity of your battery, simply change capacity in app.
And another thing, that discharging battery overnight is some rogue app, that wakes your phone regularly, or application which doesnt permit device sleep, you can check this by checking your whole time of battery used and wake time, if its almost the same..there are this kind of app.
I have this problem, but cant find out which app it is.
My L9 P765 have 2150 mAh battery as offered by LG and works amazingly great. Given TWO FULL DAYS (48 HOURS) with heavy usage and 3G on for most of the time in a day. Its rooted and I have removed some LG crap apps which roll in memory all the time for no good reason. Also use ATK with every half hour crazy killing.
Hats off to LG for such a huge battery backup with such a thin battery. No I am not LG salesman, rather a long time LG hater due to O2x , delay in ICS and locked bootloader..
Done hard reset, some settings (disabling some pre-installed apps, turned 3G off, and so on)... nothing new installed and wake time is still same than up time. Do someone else have similar problem ? (I assume that up-time is upper time in battery usage graph, and wake-up time is lower one)
I am using battery spy with my L9 to monitor the battery voltage.
When charged to 88% the voltage already went up to 4.24V ..... that is way over voltage .... and yet it still continue to charge.
Should I trust the voltage from battery spy?? What other Battery App do you use and have your noticed the same over voltage issue??
I have charged my L9 to full twice since I received it few days ago .... without knowing/montoring the battery voltage.
If it indeed let the battery over charge like that the battery will goes to smoke very soon.
Your comments please and thanks.
This phone have 2150mAH battery which is too much more than standard batteries (1300 to 1600mAh), hence the battery is not so bad how it appears with you.
Even without any tweaking it should go above 35+ hours, as I dont have anything special, its pure V10C Stock with no memory tweak, except ATK.
Now if you pals are really getting so bad performance, I suspect the bad battery issue. Its possible in thousands of phones sold few may come with bad battery in-spite of factory testing.
Just a tip. If your phones and batteries are in warranty, please get it checked or replaced as few hours life is certainly not reasonably possible with L9 as per my observations.
Also have LG Optimus 2X, with three years old battery and still giving 24+ hours uptime on recently flashed Stock V30B ICS KDZ. I already mentioned, with L9 I got two full working days with business usage, calls, emails, 3g, wifi, etc. Or am I too lucky?
cmahendra:
Do you have any app that can show the battery voltage??
What is your battery voltage when it is charged to 100%??
Thanks.

I think this app shows mAH usage. Its free and shows hell lot of information. May be this or its PRO (paid) version. Not sure. I have not used it but you should search a little too.

For me same. 48 hours, stock rooted V10a L9 P760. 2 hours of calls, some SMS, Wifi, Angry birds...
But when I launch NFS MW it goes down in few hours
thanks for the app info. I have installed another battery app and the voltage reported is the same so I will be running battery spy only for now.
For me keeping 3/4G mobile data on kills my battery. After 6hr49min idle (phone screen off I get the stats below:
- 48.7% deep sleep
- 43.8% @ 300mhz cpu
- 6.9% @ 1ghz cpu
- Battery lost 27%
- this is with WiFi/BT off. Only Mobile data on.
- 769BK 10e Stock ROM. Nothing changed.
With mobile data turned off and only WiFi the battery life seems to have improved A LOT. Will confirm that with longer term testing.
I am on T-Mobile $30 plan and my area is marked as the best signal in their coverage map.
For me it may work ok cause I am using csipsimple/pbexes exclusively for voice call; I just need to manage to turn off Mobile Data whenever I have WiFi coverage; but if I am on the road for extended period battery will be a concern. May have to get an extra battery.
I recall seeing a list of apps that can be safely disabled but lost the list now. Anyone have info for that??
Any other battery tips??

Woow 24h with the lg o2x.... mine is 20h max at home with wifi. And out side like 15h maybe with only 2g and data on...
Stock battery.... on cm7 didnt like tstock 2.3 and ics they say battery aint that good.
But should i buy this one. I mean is it the same perfomance as the o2x? I still cant find if the powervr540 is equal to tegra2..
I found out, that one of application actualization (youtube, chrome, google music play, street view, or voice search) had impact on device..keeping it awake for long time, which could be seen on battery...dunno which one app caused it...better uninstalled it all.
/edit.: according to other forums there is a problem with chrome update, which depleting battery drastically
Looks like tha weather was the problem , It got a little bit hotter here and the battery works like a charm , after a day I still had 68% .
I have the same problem! Any fix tips?

Mine goes dead in less than a day, I'm not sure if it's because I rooted my SGS2 or not (chainfire's guide) but then again before I rooted it, I had only used the phone lightly because I didn't know all the functions, but now I know it all.
Anyway, battery life is awful, how are you coping with it? Also are there like genuine branded batters that's bigger than 1650mh that will fit the SGS2?
Edit1:
OK, I have no idea why this is happening, because the default task manager widget on my SGS2 says no apps running, and I've also cleared RAM. I dont understand why, I'm not using some of the programs, like internet or clock etc.
Also, Advanced Task Killer doesn't show xScope 6 or PowerAMP or Clock as running under services, but Battery Usage still picks it up?
Display: 37%
xScope6: 11%
Android System: 9%
Voice Calls: 9%
Clock: 8%

Social Hub: 6%
Cell Standby: 5%
PowerAMP: 4%
Wi-Fi sharing: 3%
Phone Idle: 3%
Edit 2:
Even after I properly exit programs, instead of minimising, it is still using the battery...
The same programes are still using battery even after I turn phone off, then turn phone back on, i immediately check the battery draw, and bam there they are
Really not having any issues with mine, infact im rather impressed. Have 48% battery life left after 12 hours of fairly heavy use is pretty good in my books. Im confident I could get 2 days use out of this thing if i wanted to.
Just do all the obvious battery saving things you can do!
mine lasts me a good 2 days, with moderate to heavy use, still installing all the apps I want and widgets etc.
Could you post your battery stat screens on usage and stuff?
I want to get a better idea by what you mean by heavy
Mine gets close to dying half way through the day with what I guess I would consider heavier usage. "Display" is definitely always the biggest battery hog haha
With Android OS or System coming in second

It seems like some are getting excellent battery life while others get horrible battery life without any kind of consistency. After I unplugged my S2 this morning I used it to surf the web for a few minutes, played a simple 2D game and then left it idling for an hour and it was down to 70%. Now, 5 hours later, with practically no usage at all I'm down to 45%.

Could you post a screenshot of the graphs?
I guess I must use mine way more than the people here who are claiming all day with heavy use. Because my Display is at 51% right now, and my battery is at 22% after 7 hours
I use mine a lot at work and have the screen on a lot of the time.
I thought these AMOLED screens were supposed to be more efficient than LCD? I could have my iphone 4 screen on all day and I didnt have a battery life problem lol
Hi,
I'm in the same situation. I've found battery life to be so bad I'm on the verge on selling the s2 and buying an iPhone 4. My battery drains at rate of about 1% every 2 mins of use, with the biggest drain being the display. Currently I've lost 28% in 40 mins of use. That's 1% every 1.4 mins.
No apps were running except web browser and wifi.
Would a new battery help? I can't find any official Samsung batteries online, and I don't really want to put a cheap Chinese battery in.
Everyone has updated to XWKE2?
battery life is very poor

I bought a sgs2 two days ago, but the battery is very poor at the moment. Mine buildnumber is XWKE1 and the kernel is 2.6.35.7-i9100xwke1-CL181974root.
how can you update to XWKE2? if i press look for update, then there is no update availible.
battery monitor widget; estimates:
all-time averige = 3h30
average since (un)plug = 6h56
battery (dis)charge = 5h43
offtopic:
Also an weird thing is when the screen goes of and you turn it back on that the sgs2 tries to remove my SD kaart 8gig and then tries to prepair again...
I didn't root my sgs2 (i have a dhd which i have rooted with miui... fantastic!!)
My build says XWKDD, whatever that means. Can someone post noob-friendly upgrade instructions please?

I'm getting results similar to yours, the best I've had so far is 9 hours, with absolutely nothing running, no wifi, and not waking it up. It's ridiculous... I'm hoping I just need a new battery, but like you I can't find any official ones.
I updated to the latest XWKE2 firmware, but it did not have much affect on the battery life. It's still VERY poor. I'm still within the 14 day no quibbles return period, so I'm very tempted to return the phone, or at least ask for a replacement. The frustrating thing is that some people are reporting fantastic battery life.
Play.com are selling replacement S2 batteries from May 20th. You can preorder on their website.
The battery life is really not that bad, here's a post from someone on phandroid;
Scainer said:
Well.... 3 days 3 hours isn't bad from a single charge.. lol (or is that 3d 7h ???)
TBH, the phone was mainly used as a phone with the odd bit of net surfing. No games, and only a GPS sync test e.g. less than 2 minutes.
I only had about 4 calls on it, and data access was only on when I wanted it.
I guess this goes to show that you have the option to use it as a phone rather than a media device and you get a good weekend from it.

And then I tried it out, and I've had my Wifi on all day, had a few phone calls, lots and lots of texting, some browsing, youtube and facebook on wifi and 3g, and a little bit of gps and it's been going for 20 hours and 30 minutes and I still have ~50% of battery left.
If I play games constantly I'll get around 8-10 hours from it so far.
Your one of the lucky ones. I'm lucky to get 7 hours on moderate to heavy use.
Its strange how some people arnt getting normal battery life. A faulty batch perhaps?
Im on 40% battery after 13 hours off charge and ive used it a fair bit today (A couple of 20 min phone calls, some texts, half an hour of angry birds and half an hour of web browsing and i also took about 20 photos aswell) To be honest im massively impressed with the battery performance. My old nexus one was usually down to 10% after a full 12 hour day.
I just hope people arnt getting the impression that the battery life on these phones is bad when theres only a few people having problems (and maybe they have a faulty phone).
mine lasts around 18 hours wifi-on gps-on auto brightness sound on around 15-20 calls a day and 200 texts a day
It's always like this on every device. Really depends on the user, software, and cell strength.
I got my S2 a few days ago and flashed Cf-Root and the latest checkrom a couple of days ago. I knew battery life was a big issue with S2 so i thought i'd check how mine was performing.
I left the phone charging through the night and after unplugging the battery is down to 80% after just 5 hours. What makes things worse is that the phone has been unused for about 95% of that time. All i've done is send one SMS and flick through my settings a couple of times.

Display being 44% is puzzling since its only been on 30 minutes at about 50% brightness. Android OS is 39% and when clicking on that it says it has been used just 22 minutes (CPU total).
I a real S2 and Android noob so i really have no idea whats going on. This cant be normal surely?

Your display has used 44% of the power used = 20% total so your display in five hours has used about 9% of the battery .
Search all the battery posts and read them for clues .

I've installed Better Batter Stats although i dont really know how to use it and interpret the information. I've included some random screen captures in case they're important.
Heya, I see that you have WiFi on pretty much and that's quite a battery drainer. It shifted my battery consumption from 1-3% while sleeping to a whooping 25+% (about 6-8 hours of sleep)... make sure you turn off wifi and data services when you're not actively using your phone

Yeah, but you can get them when you use your phone again. I can't speak for everyone but I never have wifi on while my screen is off, it wastes battery and I don't have a social life/need to keep my Internet on

After doing some reading one thing that may be causing this is not calibrating my battery.
When i received the phone it came without about 60% of charge so i just plugged it straight in to my PC figuring i'll let it charge to full while i play around on it. Unless i'm mistaken this was a bad thing to do?
I've downloaded Battery Calibration from the market and i'm currently waiting for the battery to charge to 100% before running it. Hopefully it'll help things.

The best way to calibrate the battery is to actually charge to 100% (make sure the phone is off) then unplug the battery for about 90+ seconds, then plug it bin and use your phone normally until the battery is depleted to 3-7% then charge fully. BTW I HIGHLY doubt that's the PROBLEM.

So once i've calibrated the battery and find that that isn't the problem how do i go about investigating what is the problem? I'm far too much of a noob to work it myself
I'm considering flashing back to stock firmware and seeing what happens with that.
Reading numerous threads on these forums I've found out that there is absolutely no need to calibrate the battery in SGS2 with any external programs / processes. The battery calibrates and maintains itself during its lifetime (something about a controller chip being integrated inside them).
If I may recommend, flash SiyahKernel , apply the battery optimizations through CWM (install zip from sdcard), and just work normally with the phone for a few days, making sure you remove all unnecessary applications and turning off data services whenever you don't use the phone.
And if you still get about a day of battery with moderate usage, it's very good for you... the stock battery just doesnt live that long with the powerful hardware that is in the phone
Hi,
I just bought an S3 over the weekend, so far it has been a delight to use and I have a question or two regarding the battery life. I am finding the battery great when I am using the phone, it drops much more slowly than I expected a 4.8" quad-core monster to do It is just the standby time that is concerning me.
Is it normal to have the battery level go down by about 20% overnight? For example, when I went to bed (about midnight) the battery was at 77%, this morning when I woke up at 7am the battery was showing 59% when I dismissed the alarm. That's 3-4% per hour. Running stock, unrooted, XXBLG8.
By comparison with other phones I've used, a HTC One S C2 loses about 2-5% overnight. I do notice that the HTC seems to switch the WiFi off for a good part of the night, though.
Also my phone seems to be suffering the 'cell standby dominates battery usage' issue, but as I understand it that's a bug with how the usage is reported and isn't related to the actual battery life.
You have to flash a cell standby fix or something to make it report the battery life correctly.

You have to use Betterbatterystats and run it and detect what uses your juice.

There next you have to unbloat your phone. Remove or freeze with Titanium backup
http://forum.xda-developers.com/showthread.php?t=1634624
At end your S3 have to use max 2-4 % per night wifi and wcdma switched off on gsm mode.
All of the above suggestions worked to reduce consumption while sleeping for me.
Cell Stand By Fix was the biggest help.
Have you made use of any of the built in power saving options?
Another big help for me was setting the wifi to remain off while the phone was locked. Seemed to save a lot of battery power. Not a setting for everyone, especially if you require receiving emails, or other data related msgs while you sleep. If you can wait until you wake its worth a shot.
Thanks.
I've installed BetterBatteryStats and the Battery Monitor Widget to get a better picture of what's going on. Hopefully it will be just be a rogue app or two that I can just blow away.
Also noticed with WiFi Analyzer that the phone's WiFi reception in my bedroom is quite weak (happens with all the phones I've tried but not the iPad!). That's probably making any problem worse.
Using TB to remove the bloatware needs root so I'll wait a week or two before rooting; I just bought the phone and want to make sure there are no (obvious hardware) defects while running on stock first

I just bought an S3 over the weekend, so far it has been a delight to use and I have a question or two regarding the battery life. I am finding the battery great when I am using the phone, it drops much more slowly than I expected a 4.8" quad-core monster to do It is just the standby time that is concerning me.
Is it normal to have the battery level go down by about 20% overnight? For example, when I went to bed (about midnight) the battery was at 77%, this morning when I woke up at 7am the battery was showing 59% when I dismissed the alarm. That's 3-4% per hour. Running stock, unrooted, XXBLG8.
By comparison with other phones I've used, a HTC One S C2 loses about 2-5% overnight. I do notice that the HTC seems to switch the WiFi off for a good part of the night, though.
Also my phone seems to be suffering the 'cell standby dominates battery usage' issue, but as I understand it that's a bug with how the usage is reported and isn't related to the actual battery life.

Cell Stand By Fix was the biggest help.

That fix DOES NOT reduce battery consumption. If only fixes that in the battery graph standby is reported to take a bigger share (10x bigger) than it actually does but does not affect the "charge left" calculation in any way.
Not a setting for everyone, especially if you require receiving emails, or other data related msgs while you sleep. If you can wait until you wake its worth a shot.

For one, apps like Juice Defender may help a lot: they can disable data network or Wifi and periodically (I typically used to set it to 30min) re-enable it so the apps still get their sync, then disable it again.
Alternatively,making the phone fallback to 2G data network will allow you to realtime-snyc without draining battery. HSPA standby seems not to drain noticeably more than 2G on the i9300, but fast dormancy doesn't work everywhere correctly so your mileage may vary.

It's not normal. I'm on stock rom but rooted and undervolted. Mine only consume 1-2% during sleeping time. It's better to know what causes the drainage. Use betterbatterystats. Then you will found out if it's an app or your carrier. Fast dormancy is enabled in other carrier which leads to better battery consumption during idle.

As already stated, the cell standby fix has nothing to do with battery drain, it fixes a wrong reporting of cell standby stats, it will NOT sort out battery drain

Hello guys,
As the title says, I too am running into some battery trouble (shocker, I know). I'd like to point out that first I did my research in the HOW+ forums + faqs. So, here's the situation:
Today with 80% of battery i played sonic dash for 45min. After that It shows 40% left. I shut down the phone. Put it in the freezer for 5mins (why not?) then turned it on again. Then it shows less than 16% at startup.
Two weeks earlier i used Navigon gps for 1hour on a full battery, after that i had 50% left. Restarted the phone and it showed 40% and afterwards started going down fast as hell in 1 hour without me turning the screen on. Seriously, at the end I had the 4 low battery alerts in a quick row (14%, 9%, 3%, 1% and then shutdown in 5-10minutes).
I bought the phone in march and used it heavily at first. I was all about thd games (which all push the phone to its limits) + occasional big downloads + uzipping heavy files. Then later i calmed down and mostly used the phone in the evenings before sleep: loads of browsing + youtube + emulators (which, all three combined, don't drain the battery that much even after a long time).
The phone has been rooted for 1 month. I'm still on stock rom. I greenified most of the processes (like every apps and games except viber, tango, whats app skype, line, twitter, facebook, vine) and froze (with titanium backup) google+, gmail,chrome, htc tips, play books, play movies, play kioske, play music, htc tips, htc watch.
Here is my question : do you guys think i should try some battery recalibrating or should replacing the battery do the trick? Or maybe there's nothing to do and the one x+ is just doomed in that area.
In one month I am going to Japan for a couple of weeks and I'll be needing a lot of my HOX+ so I sure wouldn't want to spend money on a new phone (with the next gen devices right around the corner) or on a pricey mugen external juice case. Any piece of advice or info is welcome.
Thanks in advance for your time guys.
Hey dude,i had similary problems with my battery.i tried everything from flashing special customs to battery doctor apps/widgets stock rom.but nothing solved the problem.only one thing,a replacement part for 23€ from ebay.the battery its selfs.

Danke.
So you say you had the battery replaced. May I ask if you did see a significant difference once the new battery was installed? Also im curious, after how many months did you replace it and how heavy were you using your phone before?
Again, thank you, much appreciated.
I've had similar issues with my battery. It has definitely gotten worse as time goes by. I did however just get a response from HTC about what to do about the quick battery drain when my phone hits 15%.
This is what they said:
I apologize for this behavior that you are having with the battery on your HTC One X+. The culprit in this situation is not the battery, it is the charging logic. Therefore, I advise you to recalibrate the battery/charging logic with the following steps:
1. Charge the device for at least 10 minutes
2. With the device truly OFF while still being plugged into the wall outlet, push in and hold volume up and volume down AND power button, for 2 minutes.
3. Let go. Device will boot up, and battery/charging logic are re-calibrated.

I cannot test this as the current ROM I have can only do a soft reboot, thus I cannot shutoff my device. Hope it helps at least a little.

Rapid drain from 15% -> happens most of the times to EVERYONE, its not individual phone problem..
So unless HTC's calibration method doesn't help just need learn to live with it :/

I suffer a lot from this issue (rapid drain from 15%->0%).
I think the battery capacity is measured/reported wrongly by the OS, because battery stats app measures the battery at 1832mAh (fully charged), not 2100 which is supposed to be...

I had this problem and I left the phone at the service for a warranty change of the battery.
They've changed it and I must admit that the problem has been resolved. I can now see how the battery drains step by step: 15, 14, 13, 12, 11 etc. It does seem to last a bit more now, maybe half an hour.

I shattered my phone screen, and send it to service, and i told them about battery problem, now they replaced battery, and earpiece speaker as i had low volume, will see how it works after i get it back in 3 days.
The battery bug was introduced in the only update for HOX+, everything was fine before the update. It starts mostly after a few days without a reboot. One time I've had theoretically more than 40% battery level, while in the next hour my phone wouldn't even start because of empty battery. Recently I was goofing around with Tasker. When the battery level showed 20%, my phone shutdown.
Did anyone test the recalibrate thing? Can someone explain me how am I supposed to hold 3 buttons for 2 minutes ?
So got my hox+ from HTC back now, with battery replaced, and now its working properly, listening music since 14% -> 1% for like 45 mins and turning screen here and there to change track, and phone turned OFF after being few minute on 1%.
Not to mention battery lasts about 20-30% longer now, hope it holds like this

Thanks for the info!!
Did you relock the bootloader/return to stock before sending it in, if it was unlocked?
And did the relocked bootloader raise any issues with the warranty?

Hi everyone,
I have exactly the same problems that what has been told before... (Very bad battery life, specially when I'm using 3G data... and when the battery is under 20%, the phone stops completly only few minutes after...)
(My HOX+ is on ViperX+ but before I flashed this rom the problem was the same...)
I tried to do a recalibration of the battery but it didn't solved the problem...
I also tried the HTC instructions listed on the topic before, but it absolutly changed nothing.
My HOX+ is still on waranty but I ordered a new battery to change it by myself (I don't want to change the rom and relock the phone to send it on warranty, I prefer to do it by myself...), and the battery (annonced as genuine) cost about 26€ on Ebay delivered ($35 approximatly)...
I will come back here to tell you if it solved the problem!

Let's talk about this in the next month...
Small update about this.
I contacted HTC support and told them about this bug. Of course one of a consultant's suggestion was "factory reset" and "repair it", as always . But he suggested to wipe android cache via recovery. I did this 10 days ago with no hope this will help, but so far it is working. It seems as if the battery percentage goes quicker up when charging and the level shows now correct values. I will wait one or two more weeks to see if this really solved the issue. So far, it might have been simply luck .
I asked HTC's consultant also about the "hold three buttons while charging to calibrate battery" trick. He said that this trick is not present in their fix database. Weird.
I found this trick on another android website
http://forums.androidcentral.com/ht...g-red-while-charging-rapid-battery-drain.html
It looks as if it is not a safe solution?
Hello,
So i bought the G2 mini last week and i am a bit disappointed by the battery life. i can't go more than 4-5 hours of screen on time.
The problem ist that "Android OS" and "Android system" are each draining about 19-20% of the battery. Even after a factory recet it is the same.
On the phones i had before these two were about 10 % TOGETHER.
So does anyone know if it's normal?
Thanks in advance
I have same problem.
Did you tried to look what apps is draining your battery ?
It happens without any apps on the phone. Just after reset. So either it is normal or it is a bug on the phone. But i think it is getting better know. I can get average of 6 hours screen on now. But still not normal i think
I have a similar problem. Bought my G2 mini three weeks ago. Seemed good battery life to begin with. Now, intermittently, it's draining up to 2% an hour in idle (just syncing a not-much-used email account over wifi). It's Android OS which is using up the battery, not apps, according to Android's battery information. And it even did this a bit when I tried in safe mode. But sometimes it works great, with very low battery drain. I did a factory reset last night, and the battery drain has been only 3% in five hours. But I'm not sure I trust that it will stay this way. I have a week to decide whether to return it!
(This is the second problem I've had with the phone. Until a few days ago, it would be using 10-20Mb of data a day, which is a big deal when you have a 500Mb contract. Again, it was Android OS that was using up the vast bulk of this data, not me. This behaviour seems to have calmed down a bit in the last few days.)

If it is 4.4.2, then that could be the reason!
Google Built a Bug into 4.4.2!
Hmmmm. let's see on GSMArena. [LINK]
Oh, no! How Horrible!
---------- Post added at 15:32 ---------- Previous post was at 15:31 ----------
The Bug is: AndroidOS-Process eats up your battery.
Mine is 4.4.2.
What's the bug? I haven't been able to find anything about it. And I can't see anything on the GSM Arena page you linked to. Is it a general bug in 4.4.2, or specific to the G2 mini?
Thanks!

Battery drain is not for 3g or 4g power consumition. If 2400 mah die with 3g in three hours, what about moto g or other phones...
The problem is fast dormancy. I desactivate it. If you want i can make a tutorial.
With 100% 3g and fast dormancy battery last 12 hours with 1h 30 screen.
With 100% 3g without fast dormancy battery last 48 hs with 4h screen.
Oh rats, this is the 4.4.2 camera bug, isn't it? Only for Qualcomm devices? I did actually know about that bug, and then forgot about it again, and then bought a device with 4.4.2 and a Qualcomm processor. Dammit.
If so workarounds might be: when you use the camera, pay attention to the battery drain afterwards, in case it has activated the bug. If there's a drain, reboot. Turn off the "Smart screen" and "Smart video" settings, since having them on would also activate the camera, which could also trigger the bug. I had those "Smart" settings on until yesterday, so maybe that's what was causing the problem for me.
And in the meantime, cross fingers that LG will upgrade us to 4.4.3 or, preferably, Android L, thereby squashing the bug.

LG had patched that........
3G/4G is very much the reason of all battery drain on my device, today I've gotten alright battery stats with no data connection except for WiFi, haven't deactivated anything but data and used my phone for a lot of youtube/browsing/ chatting. So I believe if you cannot go above 5 hours of onscreen, it's properly due to high usage of camera, or data and WiFi running when not in use

I never had that issue after using camera. You need to check if the process is starting on setting/battery. (That will not start because LG has patched that at least on my country, because I never have that)
I don't know what's going on. Today I didn't use the camera, and the battery seemed fine, and then I took a photo, and it started draining at 1-2% per hour again, so that made me think I'd found the problem. But then I hear it's patched, and anyway if it's the classic 4.4.2 camera bug, it should show up as mm-qcamera_daemon being the process using all the battery, and it doesn't, it showing Android OS doing so. I feel like I'm back at square one, not knowing what the problem is or how to workaround it, and thinking I have to send my new phone back...

Your problem is fast dormancy for sure. I told you that a few post back..
LG comes with fast dormancy activated by default for all operators and some of them dont have fast dormancy so make a fast 3G battery drain. If you drain 2% of battery in a hour with wi fi you can install battery stats and see what app is eating your battery.
I get intermittent battery drain with either 3G or wifi.
But if you could tell me how to change the fast dormancy settings, I could give it a try.
Also, not convinced that it's an app draining battery on wifi. According to Android, it's Android OS, not an app. Or is the Android battery information so not reliable? In that case, can you recommend a battery monitor app?
Thanks.

When Android operating system is draining your battery, is an app on the backgrpuns. You can use better battery stats. Just search in google and will apear.
If Android OS is draining, its common i also have 10% of drain because of that. But it dont drain too much so you dont have to worry. My xperia m2 says android os 60% when idle, but battery drains normal so just dont worry. If you feel a big battery drain use your phine to 100% to 10% and give a sctrenshot of battery graph.
Press thanks button, you are welcome.
