Unusual battery issue - LG Optimus G (International)

Hi guys,
I'm new to the forum. I recently changed my note 2 in favor of the E-975 and I'm pleased with my new phone. I do however have a (unusual) question about my battery usage; is it suppose to be this bumpy? I mean, it sometimes, as can be seen in the image posted, goes up from say 79% to 80% when I use it. I have never experienced anything like this on my previous 7 different android phones. Thanks in advance. (English is not my native language)

I have a E973 and the my battery discharge curve looks like yours.
Have a look at battery posts in the Optimus G forums and you'll notice that bumpy curves are quite frequent...
Is it hardware or software related I can't tell...
It looks like if the battery level was calculated using only the voltage so it fluctuates wildly depending on the current drawn from the battery...
I'm assuming that modern designs like the Optimus G use a fuel gauge to calculate the battery level so things like this shouldn't happen...

Im sure its software.
I believe thats a trick by LG to make the phone play longer

I also believe it use a fuel gauge, but damn, the one in that phone is ****. Never saw a gauge that bad.

Thanks for your thoughts guys, I'm now convinced you're right.

Something we keep forgetting Re: battery life

I've become obsessed with the poor battery life on my new Galaxy Nexus and I've been pouring over forums, videos and blogs to find out why it's so bad.
I keep hearing about people getting 8 hours, 11 hours, 14 hours before their phone dies, but this is not actual use time, it's idle time (I.e "I left the phone off the charger overnight and..."). WHY does the manufacturer rate this phone as having a 15 day standby life... FIFTEEN DAYS!!!!
Something is terribly wrong here. If I can't use the browser for more than an hour without the battery getting critical, then what's the point of a "super phone "? It seems useless. I don't even want to install games on this device, because I know I'll get frustrated by it chewing through the battery as I play.
I purchased this phone with a high priority on the HD video recording capabilities, but will I actually be able to film stuff while out and have enough juice in case I need to make a call? Something tells me I won't.
Maybe I'm just expecting too much or maybe manufacturers should stop making these phones so "super" and focus on the fact that these are portable devices which need to last at least the day. God forbid you went for a hike and had an emergency, only to find your phone dead after eight hours!
Rant over
My battery is currently at 60% after 13 hours and and 1:35 screen time.
I have absolutely no complaints about the battery. In fact I would say its the best out of any phone I've owned.

That's because when you pull your phone off the charger and it says it's @100%, it's lying. It's somewhere in between 95-99%. The first 10% is spent figuring out where you're really at.
I think op said it best himself. Maybe you're just expecting too much. Battery life is freaking awesome for a phone with a 4.65 inch oled screen. Reminds me of my trusty nokia e71 back in the day.

If your battery is properly calibrated, the first 5% is iffy. Just figured out how to properly calibrate less than two weeks ago and it doesn't include any software, like batterycalibration or resetting battery stats in cwm.

You can kindly replace "hike" with "family outing", "work", "movies", night club", "sporting event", "errands", etc... having a spare battery or charger (or a second communication device!) on you all the time should NOT be the solution to poor design (either hardware or software or both).

Lot's of misinformation in this thread.
A new Lithium-Ion battery (LiCoO2) is always 100% fully charged at 4.20 V (+- 0.05 V). This maximum voltage lowers with age and use of the cell. Both voltage and battery age can be precisely measured by your phone and translated into the battery % display. It's not a linear graph but it's not really rocket science either.
There is no calibration of LiIon cells, it's neither necessary nor possible, they work at 100% efficiency right from the start.

i'm at 24% after 12.5h, 1:45h screen time (inverted theme browser and some brief facebook/twitter time...). This, to me is not acceptable. If I was using google maps + gps, how long until the battery died? 30 minutes? Less?? I'm not watching video, making calls, downloading torrents, using the camera or anything else that would cause this kind of drain, but it seems to be "normal" for a lot of users on this and other forums.

Have to agree with most and say battery life is by far the best compared to all other Android phones I've owned. As for standby time, this is tested without a sim card, apps, etc. So 15 days sounds reasonable without touching it and without the phone doing anything in the background.
I disagree.
The battery life of this phone is fantastic, more than what I expected. It is better than the Nexus S that I have.
I am using extended battery 2000mAh for GSM version.
Battery drain during night is about 1%-2% for about 8 hours. No kidding, I was surprised with that this morning. Probably because the new 4.0.2. Before, it was half percent an hour.
My current record for battery life was 61 hours with 4 hours screen on time. See the attached screenshot.
Again, this is based on my usage pattern.
Sent from my Galaxy Nexus using xda premium
Battery life is amazing to me too, My average usage a day at work is 8-9 hours music, 45-60mins 3g web browsing, ~1h 40 mins screen on time.
On my Desire HD (Yea I know, hopeless battery life) the battery would die around 7-8 hours in with that usage. On my Galaxy Nexus I get home with 50% left.
One thing I found that helped battery life out a TON, is swiping facebook off the recent apps menu when you're done with it. Also have a similar high drain problem with joystiq/engadget apps.
Running AKOP17 with francokernel12 for anyone wondering.
I think you need to specify CDMA or GSM. It seems pretty common for GSM to get around 4 hours screen time before the battery goes. CDMA: 2.5 hours or so with moderate-heavy use.
I really hope someone on Verizon will post that they get 4 hours screen on time (no wifi) and what they did to get it.
Battery is good here too. Android OS is the eater. 4.0.3 and a good kernel fixes that.
The phone is capable of good battery but the new OS is still buggy.
LTE EX Galaxy Nexus - AOSP KANG
Asus Transformer - 3.2.1 OC/UV
Franco Kernel with a core powered down on screen offm 325 / 1200 clock.
Exiting / logging off google talk
Entering camera and force closing it one time after each reboot
LTE off
Nets me 1% drain per hour on 3g with nothing going on. That is excellent battery life. Loging out of Gtalk netted me approximately 2% an hour and the camera close trick netted me a crap ton. Prior to that I was getting almost 8% per hour loss doing nothing.

did u try calibrating the battery with any of the free software on the market !
i used to get 3 hours "seriously" out of this phone ... after deploating and calibration it can last 12 hours with heavy use !
I've started using an external battery charger (one of the official lg ones from Ebay) and an extra battery, and just swap them out when my phone dies, and I've noticed on the few occasions where I charge my phone by plugging it in, even though it says 100% (and I've done all the battery calibrations and everything) it doesn't last as long as when I pop in a fully externally charged battery.
My device battery life also got better in comparison to the first days i used it. But for some reason i experience some strange usage right now.
For example:
In the morning from 7 - 10am 100%... later 10% in 15 minutes, with phone in standby-mode.
I checked after i'd make a phonecall, hardware consumption for radio was on 99,9%. After reboot it was ok again, but later hardware consumption for the screen was at high level. Strange... everyday a new experience.
Turning LTE off helped my Spectrum last 24+ hours. I turn 4G on whenever I really need it, though. And with 4G on all day, I can get 12-16 hours under moderate use.

+1, better battery life than stock ROM
I have honestly never seen a phone go through battery quite like this one. I love the phone to death. It feels solid in the hand, and the screen quality is amazing. But I can't deal with the battery going like this. I input a new APN so it would just use HSPA+ .. but does that actually stop the LTE radio from searching? (I am in a non-LTE area)

Yes our screens are a big consumer of power but there are plenty of disadvantages to AMOLED: heat, image burn (like a plasma tv), image quality and longevity of the screen. The more pixles that are lit the more power it uses, to the point that it uses more power than IPS with large areas of the screen are lit. This along with image retention is why CM7/9/10 has black as a background for everything and stock doesn't. Think of it as LED/LCD TV's vs Plasma. Similar power curves between them.
BTW the little program above dropped my idle power usage to only 5% over 8 hours. I will be trying it with cm10 to see if I get similar results.

[Q] strange battery drain (updated)

I'm not complaining about battery life bit I just fond this strange how with nothing running my phone went from 20% to dead that fast. Phone was locked and in my pocket. Anyone have any ideas? It's also not the first time this has happened either just the first time I thought to get a screen shot of battery usage right after
**Update**
Now my phone is dying at random :/ it does it from 50%, 30% etc. Any suggestions (i.e. battery calibration, full factory reset) or should I make it stock again and get a replacement?

Batteries are gauged by how much voltage they are pushing in most tests. Though from my hobbies of electric rc cars, I've learned that batteries can change their voltages simply from a temperature change. While these changes may not be significant, they do represent differences and used to play a big part in my fifteen minutes charge cycles. It's harder to receive a positive rating in a cell that is low on power than it is with one on max charge. So if I'm down to twenty percent or so, I use my phone very sparingly. Has been pretty trustworthy for me over the years.
Either way, suspicious battery drain is usually a rogue application sitting there eating resources as the phones we use do seem to monitor battery life pretty good compared to the old voltage meter methods.

I found the htc-Facebook app drains funny on the battery. When I loaded bonestock, then loaded Facebook from the play store, it helped my battery. I think it's the way the htc-Facebook interacts with blinkfeed.
Could be completely of base, but I know the htc loaded Facebook is slightly different.

I assume you had a good signal everywhere you went? Nothing drains a battery faster than being in an area where there is very low or no signal. It constantly tries to connect and it will KILL your levels very fast. I see this quite a bit in my work place. Employees with Sprint and many times AT&T will complain about their battery dying at work only to find out the phone was constantly searching for a signal.

You know, I totally forgot about that. I used to have that issue with Sprint myself. Killing the data would eliminate TONS of battery usage when I was at work. Now that I'm on Verizon, there's never much problem. But he's completely right. If you're not getting a quality signal your phone may be searching and that can be an all day thing which just eats a battery alive.
I am in a near perfect signal. I'm pretty sure its has nothing to do with coverage. What's strange to me is the phone immediately dies. It will be at 50% and then the screen goes black and won't come back on. Once I plug it in the phone finally comes back on and is at zero.

Basically, the more you drain the power before charging, the less charge cycles the battery will have. Someone who charges at 75% compared to someone who charges at 25% will have more cycles over the life of the battery. I can't remember the exact numbers, but there's been plenty of studies on the issue. And if I'm correct charging at those numbers, the 75% will have more than twice the charge cycles over the life of the battery. The biggest battery killers though are actually higher amperage charges. One study showed more than five times the life cycle at 3.7v per cell compared to 4.3v. And the charging required to power the higher voltages actually cause more damage over time than the extra mah output is worth. The HTC one has a decent setup and the stock charger doesn't over feed the cells. But in not sure if it will make it to the 700 charge cycle that a two year contract may leave a user with.

Bad Battery Backup??

Hi,
I have been getting only 20 hrs of battery and only 3 hours of screen on time. I have not used any processor intensive apps. Please check the images attached. Is this normal? I have bought it a week ago and I can get a replacement if the battery is defective. What do you think? Don't plan or rooting it.
P.S: I have chosen ogp over n5 because of the extra battery, but ogp's battery is equally bad.
Normal usage.
After playing 1hour of injustice i get around 3.30 of screen on time.

You need to understand that they provided the extra 'oomph' in the battery department, because this is a HUGE screen.
Another thing, is that LG's stock interface is filled with a lot of white menus, and submenus, etc.. That will also impact battery life more than you know.
Another factor to bring in to consideration is the cell coverage. Your phone has to work harder to acquire signal, in hard to reach places by your carrier.
All of these and more (wakelocks, no deep sleep, etc..) Have a big impact on your device's battery life.
