Battery Lifetime

Good Morning folks,
as some of you are already proud owners of a LG2x, I would like to know how the battery lifetime really is. Are you guys satisfied? How intensive are you using your device?
It would be nice, if you can describe what you are running, like wifi, gps and so on... pretty sure you know what to write to give me and the others a clear view on the battery lifetime ;-)
cheers,
Manuel

Yesterday I got the phone.
On very very very hard use it took me about 7 hours for the phone to be 0%. That is kinda good in my eyes.
Today I'm doing normal use, to see how the battery goes.
I withnised 100% tot around 60% went kinda fast, but from 60% till 0% took a while
So stay tuned for the today test.

I got the phone the day before yesterday started charging it. Then in the afternoon it was fully charged and i started to play around with it. It did good but then today i had it fully charged overnight and now - at around 15:00 it dropped below 15%! I hadn't been using it for other than a few calls, a few texts and less than 10 minutes fooling around.
Something is up - i don't know what, but the battery info shows most battery usage was drained due to cell standby and mobile standby...
I don't know what really caused this Other than that i love this phone, i just hope i find the reason for this insane drain soon - i tried rebooting and even installed advanced task killer

Hello, I cant really help much on the battery issue other than to say give it a few more cycles before getting too upset.
The last new battery I had in my iPhone took a week to really settle down.
I would uninstall advanced task killer as I believe it has issues with froyo and is not really needed.

Ok thanks - i think i will then

had the phone 2 days now, and feel like the battery drains fairly fast, had a BB before this and im not used to having to charge everyday. Will se how it goes the next couple of days.

Ok, it seems a lot of people already got their device. Is there someone who could try to unload (by heavy use or something else) and reload the battery again and again to get a feeling of the behavior after some loads?
Thanks!
Update: I have an update from a German guy for you who claims to found out that the service "nvrm_daemon" is the one which consumes the most power. Anyone an idea what it is? The "nv" in the name sounds like nvidia...

nvrm has something to do with the NVIDIA kernel module.

Yes, it seems related to Tegra.
I googled and found this little quote about the offending service on a site dealing with the Toshiba AC100 that also use the Tegra 2 chipset:
it makes suspend, sound and cpu frequency scaling work

Isnt it coz that dual core isnt supported very well in 2.2?

hey xmoo, how come your always one of the first having such nice devices? if i remember right you had the hd2 pretty fast as well back in okt. 2009.
i wanna have it toooo

48 hours.
Way better than the Nexus One. Not much more I can say.
Most importantly, not much more I will say on battery. It's too subjective and circumstance specific.

I should be clear - I do not mean +48 hours battery, I mean I have used the phone for only 48 hours... This includes charging.
But still, much better than my Nexus One. At the same time with the same apps and usage I have 40% and on my Nexus I would have 15%.
We all still need some days (~1 week) for the battery to settle.

okay in Eindhoven its in stock at a mobilephone shop. i seriously thought about to drive to the shop ... its about 260km from Paderborn
but lg said three days ago the 2x will be available end of next week. so now its up to amazon and its time to say goodbye to htc ... im really curious about the lg 2x
@xmoo thanks for your impressions of battery life. i was a little afraid of power consumption because of the dual core but that sounds fair

hi, 72 hours with the Optimus 2x and i have the same problem with the battery, it drains so fast!! with few use from 7am till 17pm 100%-32% !!! but i think today is better..
here in Antwerp,Belgium there is in stock at pdashop and gsmwijzer
kind regards

Ok i'm doing a real-life test atm after a few charging cycles.
What did I do/ have I on?
Have I on: Everything (gps, data, wifi (if possible),...)
What did I do: Some gaming, few youtube movies, few short calls, watching mails, some internet browsing, send a few texts.
I'm using the app : Juicedefender in combination with ultimatejuice (this prolonged my battery 2.14x!!!
How long? : Atm i'm using my cell (from full charge) for 44 hours and I still have 39% left! This means that i could get it to run for 3 days on 1 charge!
Note: this is after doing a few cycles, out-of-the-box use gets you the day around!

[Q] Batterylife issue, can't find any threads that help

There's not a single thread out there that has helped me with my damn battery life that I've been able to find. I'm sick of hearing, "did you search first?" Yes, I searched first. I didn't find anything that helped, that's why I made a new thread.
Anyways, I've tried apps, widgets, calibrating, deleting batterystats.bin, flashing different roms, kernels, modems, and even a new battery. Not a single thing has made my phone last through the day, and it's getting to the point where I'm about to flash back to stock, and forget about it. I need to be able to use it when I need it, not put it back in my pocket because I'm afraid of draining the battery. Honestly I'm not sure if the battery issue is rom related, so If that doesn't work, I may just get a different phone. I need to not have to charge my phone every 6 hours. Does anyone have any idea how to improve battery life on this freakin' thing? 6-7 hours on light usage is not enough. To put it in to perspective, I get 10-15% battery drain in STANDBY per hour. Serendipity 6.4 was a little better than 7, but not much. still within that 6-7 hour range. Is there anything else I can try? Anything at all? I went from 7 back to 6.4 because I thought Android System was draining my battery, but it didn't really do anything. I'm open to everything at this point. Voodoo, cult magic, anything.
Edit: reading through my message, I wanted to clarify that I am very grateful for your help, I hope I didn't imply otherwise.
Serendipity 6.4
Baseband version I9000UGJK4
Kernel Version 2.6.32.9

Have you tried Juicedefender? It's helped me immensely. Other than that, I could suggest getting an extended battery, if you're willing to cope with a lumpy cappy. I'm too noob to know how to fix this problem other than by using the brute force route, but it's worth a shot.

Well, battery usage shows just about nothing... I was using 6.4 but after it did nothing for my battery life, I went back to 7. Now the android system thing is back but I'm getting the same battery life.
Here's what it shows under battery usage for today:
Display 29%
Android System 25%
Android OS 10%
Google Services 7%
Cell Standby 6%
Fancy Widget 4%
Handcent SMS 3%
Battery Graph 2%
Phone Idle 2%
JuiceDefender 2%
Dialer 1%
and that's it.

if you start seeing android system and android os that high, shut down, yank battery and let it sit for a few minutes. then replace and start up. should help with that and improve battery life.

The problem is, I'd be doing that every 15 minutes. It boots up already taking up more than 10%. I just did exactly what you said, and it booted at 23% for system and 3% for os.

flashed cyanogenmod 7, and turned off mobile data and wifi and just left it on idle for like 2 hours after resetting the batterystats.bin and rebooting... i uninstalled juicedefender because it was actually USING batter... *shrug* and left it that way... well, I opened battery left and looked at it and saw that it would die at like 5am... well, i was disappointed... until I noticed it was 5am, 26 hours from now. That's notibly longer than any battery left stat I've seen since I started noting battery issues... So... Yeah. I think I'll stick with CM7 for a while hehe. After I get an idle benchmark, I'll start using it more. Thank you for your help.

do you live in a poor 3g area?
the problem could be that the phone is constantly looking for a good connection and cant find one, causing massive battery drain

I was just going to say the same thing. If your phone is constantly trying to establish a connection, is alway searching, it's using up lots of juice. Same if you've got gps enable or wifi on. If it's looking, it's active and battery's being used.

Another thing you can try which helped me is to call art and get another free battery if your phone is still under warranty. The new battery I have seems to last almost twice as long as my old one. Of course make sure that the android os isn't eating the battery and mine last a while. Just a suggestion.

I agree. Also, I'd love to charge my phone in 30 seconds. It's a different approach to solving the battery-life problems.
If you can't make a battery that lasts longer, make charging faster.

That makes so much sense, I whole heartily agree

About time battery tech evolved in 1 way or another.

That's a website full of very classy people...

The energy density given is not bad for a supercapacitor, but the ballpark figure 'comparable to normal batteries is only 10% of chemical batteries.
So... your phone may recharge in 20 seconds, but only run for an hour or two.
Still it is great progress. Imagine a normal battery for the long runs, and this quick charge capacitor for a fast recharge in between.

REALLY bad battery life, is this normal?

Heya,
I've used my One for a few hours now, I'd say moderately heavy use (checked facebook/twitter, downloaded some apps, watched a few youtube video's, played Dungeon Hunter 4 for 30 minutes or so, checked flipboard).
I'm amazed by the poor battery life, especially since all the reviews were so positive. Will it get better? Could I have a faulty battery? This is nowhere near the 14 hours people have been talking about...

you can't tell yet. @Zepid, look for better battery stats xda edition and install it and post the screenshot for kernel and partial wakelocks, other and process.

It's hard to really tell with the default battery monitor, try BetterBatteryStats or GSAM from a full charge and go from there.

Also turn Power Saver on. It limits the CPU to 1.1GHz, and won't even affect gaming performance, or anything else for the matter except benchmarks. Click on the Power Saver option to customize what gets turned on/off.

You should check out the thread that talks about battery saving tips. It helps a lot and make sure you install a custom Rom such as trickdroid.
It's very battery efficient.

Don't forget that if you install a custom ROM, you'll need to root your One. That also means loosing your warranty

DH4 is a beast on battery in my experience. It is hard to play that game and not burn a ton of battery.
Anyway, when I don't play DH4 I still get 5 hours screen time. That's without power saver, auto sync disabled, and Lux adjusting screen brightness. I'm sure if I used power saver I'd get much longer.

Seriously, give it a couple of days!

Graphic intense games like Dungeon Hunter 4 EATS the battery.

Thanks guys, the Power saving feature definately seems to help, and it's not slowing down the phone at all. I'll give it some time and see if the battery life improves.

You should allow more time, at least 2 or 3 updates, to iron out the biggest bugs. All manufacturers need that time, apple en Samsung too.

Will be posting screenshots via dropbox below with a few hours in between.

In addition I've used a2dp audio stream for an hour or so. I'll do a full screenshot of all the on times later.
Still very low usage scenario. Battery looking good. @22hrs 40% with updated screenshots above.
Final Result only took me to 15% with 1 Day 16 Hours. Screen on time 3hr 16mins. Needed a full battery for the day and couldn't risk it but atleast it's a general ballpark. https://www.dropbox.com/sc/oaj33ji9kssx5rt/BFiLIz-Jef
40 Hours is still pretty good for light usage. During a busy working day i would be happy with 9 hours max usage.

It looks ok with almost 2h of BT streaming calls + 2h of music. Other results in thread seem more "realistic" (if you don't use BT). Let's wait for more feedback. If it could make 4-4.30h screen on for me, that means with custom kernel and UC it could easily hit 5h or more. *thinking out loud*

Here's my reply from the previous thread...
Well you say it's disappointing but I disagree;
If you look at the screenshots you will see how much battery has been taken by the voice calls compared to screen on time;
30% of the total battery use was from the 3hr47m for screen on time but...
A whopping 26% for only 1hr28m of voice call time! If we use that ratio and just double it (assuming all network strength was the same) you'd likely lose 52% of your battery in just under 3 hours...(this is just an estimation based on my results btw).
I honestly don't understand the hard-on people get for screen on time when voice calls seem to drain the battery much much harder... doesn't anyone use their device as a phone anymore?
Also if you take into consideration how bad my signal was the battery life I had today was all the more impressive.
A Random Afterthought:
IF that 26% that were used on Voice calls were used for screen on time...although realistically it'd probably be something like 17-20% with the rest on random android processes and processor usage; the screen on time could easily be above 5 hours possibly pushing 6 with bad signal and no wifi O_O...

Well nexus 4 with Trinity kernel gets 6-7 hours so with nexus 5 I expect around 8 hours on a custom kernel and stock should get around 5 hours which is pretty darn good.

shr33kant,
The battery performance results you have are perfectly acceptable for a typical phone user that uses the phone for calls, web surfing, google services, movies etc. I only get 2 to 2hr. 15mins on my N4 with typical phone usage as you. So the N5 is basically getting better battery performance then the N4. :good:
