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?
Should be fixed in 2.3.

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.

Dunno, I think I got the good connections
I have noticed how longer the device works, the battery gets better.
Today from 8 till 17:00 my batter cme from 100% to 69%.
I mailed, whatsapped and texted a lot and 1 small phone call.

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

hi ~~ just want to ans. the owner of 2X ....
is your handset "Made In Korea" ??

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!

Battery drain

So I am currently on 5.1.1 rooted with Franco kernel. Before updating to 5.1.1 I had 3h and 44 mins SOT and still 16% battery left. I read that flashing Franco kernel will help my battery but I am currently on 55% battery with 1h and 40 min of SOT. I have greenifyed all the battery draining apps like Facebook etc and I don't have any widgets expect Google keep. I have attached couple of pictures if someone could please look through them? I did several factory resets and still the same battery life. I am just browsing and watching YouTube videos. Now I only get 3hrs and 15 minutes before my phones dies
It's driving me nuts, I read that Franco kernel will help my battery life but it's still the same. I have around 40-50% screen brightness.

Have you done any modifications to your CPU or anything like that?
Profiles/governors etc.

No nothing. Just flashed Franco kernel free app so I can't adjust any governor

regardless what you were told, flashing kernels does not help battery. its your use and the quality of your signal that will determine your battery life. kernels might help you in saving battery, because they all change how the CPU works, but its up to you to save battery, not the kernel.

Yeah I read that you'll get better battery life with Franco but I don't know. Is there something unusual from my screenshots? Is there anything I can do? I mean I am using my phone as normal as possible and I even turned of lte and running only on 3g. I just want to know what the culprit is. I even removed viber but it's still the same issue

what percent brightness do you use? I keep mine at about 0-10% mostly, and average around 5.5h sot. if I raise my brightness to about 30-35%, I lose about an hour of sot. but really, its all about what you are doing with your phone. if you are a heavy gamer, you'll see much less sot because CPU intensive games will go through the battery quickly.

Your best shot is getting the full version of FK app and then controlling your CPU.

actually, 0-10% isn't that dark. if you set adaptive brighrnes, 0-10% will actually be darker. 0-10% is fine for me, unless out in the sun. but with 50% brightness, I'd say 3.5h sot is actually fine.

Really? I have 50% on all of my phones. I'll try 10% and see. Is activating the adaptive brightness good for battery life?
Just want to know really if my apps and system is behaving correctly. If it's the brightness that is the issue then it's a relief. But I read that everyone got better battery life with 5.1.1 except me :-/ I mean I have Bluetooth off, gps off, hepatic feedback and sounds etc all are off. Even Google now is off

no, adaptive brightness is bad for battery life.
and for the majority, battery life is exactly the same on 5.1.1, like before. as many people that claim better battery life, just as many, if not more, will say its the same, or worse.

Of course that it would help. I got 7h SOT with my old S3 running a custom kernel. But after all.. Try it out yourself

Yeah that might be hit or miss with every update. But I still feel like one should get better SOT even with like 40-50% screen brightness, I have all the big battery hogs turned off like GPS etc

first off, paying for the full app will give you what, more control of your CPU? do you know how to control tour CPU? if so, there are many FREE CPU control apps. learn what you are doing first, then buy the app. secondly, no one that uses 50% brightness gets great battery life. the screen uses the most battery, raising brightness to 50% will just let it use MORE battery.

I know that you can control your CPU, I've don't it before on my older android phones. I'll try the suggestions regarding the brightness

that, my friend, you have to find. considering that we all use our devices differently, you have to find what works for your device best. there isn't a magical setting for battery.

OK thanks mate, ill lurk around the forum and see what can be done :good:

Best or ideal kernel settings for best battery life with good performance?

The title explains it all—I'm wondering what the best kernel settings are to achieve the best battery life without completely dropping performance. I've never tweaked the kernel on any phone I've owned before, so I have no idea what those settings might be. I currently get around 5-6 hours of SOT, which is great for heavy usage but with a battery those huge we should expect way more.

I'm currently playing around with majorly under clocking the CPU (Currently testing at 1.2 GHz) and have yet to notice a difference in performance. I'll update with battery improvements if any arise.

im on zzmove with profile 6, run only 2 core at 2.4Ghz and every thing seem good
phone run cool and great in game(framerate still good and more stable since no throttling at all, before that with stock, my phone get hot and lag if i play asphat for long) not sure about battery yet but seem good

Try computerfreak ROM, i'm getting 77 hrs on battery and 6 SOT!

Oops just now noticed I had replies.
I'm currently running Resurrection Remix and I seem to be getting better battery life than I was on stock, which is odd; however, I wish to get more. Update me on those kernel settings.
Also I noticed that when I'm at school the cellular signal drains my battery considerably. The signal there is poor, is there any way I can minimize the drainage?

That's a ridiculously easy thing to do, I can't believe I didn't think of this. However, its rather inconvenient. Any other ways? I heard back in 4.4.4 that there was a way to disable certain bands or something to consume less power when you have bad signal.

I'm on rr and honestly I'm not getting the best battery. Like 3.5 hour on screen time. It does still make it through the day though. I changed the kernel settings to conservative under cpu, which helped a lot from previously getting under 3.

Settings, configs, performance tuning, kernal tweaks, then in the app in the cpu tab, the cpu governor option. That's where I found it and I turned it down and I'm getting better battery.

That's odd. I get considerable better battery life on RR than I did on stock. I've hit 5.5 and even 6 hours of SOT with heavy to medium use (when I'm not at school at least).

Same here, but I noticed it lasts much longer with Greenify and Amplify installed with Xposed. I lose about 2-3% during standby mode during the night....whereas before I lost about 10-15% even while on RR.

Just got 7HR and 4 mins screen on time with in 2 days didnt use my phone at school only when i was at home so i guess 7hr's is good..
EDIT: i am on stock ROM

That sounds right about what stock should be getting for some users. It's good to reference stock with your personal use versus someone else.
1 hour of a playing a game with full brightness will use significantly more battery than an hour of book reading on night move although they both technically have the same screen on time.

I usually consistently got about 5 hours and 30 minutes of screen on time on stock with medium to heavy usage at school and at home.
On Resurrection Remix, I usually get 5 or sometimes 5 and a half or 6 hours, with heavy usage at home. On school days, I can only manage to get around 3, which I find incredibly odd. I chalk it up to the poor signal at my school draining my battery.

You can get 48 hrs on the Turbo. You can also get 5 hrs. Like I said before, it all depends on your personal usage. Perhaps they have a baseline test they do on every phone so there's no variable aside from battery.

the battery life

What really is up with Android phone and their battery life. This been bugging me for like forever and its 4:00 AM and i have to post.
Like my sister had s7 edge and just the general messenger apps IG, WhatsApp, telegram & Weechat. Rest are game for toddler. But all the time the phone been with her, her average SOT is like four hours and the BATTERY KEEPS ON DRAINING on Wi-Fi or Data and NEVER flats out. It only does when in airplane mode. Before you guys days uninstall the games, in the battery usage graph same with GSAMbattery, Android system is like up all the time. So it has to do with Android OS.
is Android really just like this? Do iPhones person better?
I have EXACTLY the same issue with my nexus 6 rooted. When my wifi is up, none stop drain and BBS doesn't show any unusual activity.
What going on guys?

With 4 hours screen on time that is about what you can expect. Mainly when using things like weechat which is notorious for uploading all it data over and over again to its servers in China. Then you have whatsapp which is done by facebook which are known for some of the worst coded apps for battery drain in the market.
Your biggest issue is the screen on time. $ hours is a bit ruff on a device. As the screen is the biggest thing to take up battery. Unlike the iphone which uses a less intense screen due to its lower quality res.

Bro, you should use an iPhone and see! It's much worse than Android. iPhone have less size batteries and you can hardly get through the entire day with one charge according to your usage. Although apple's implementation of background apps optimization is excellent, but still the battery life is less due to small batteries. I feel android is much better in terms of battery.

Totally agree.
You can add that android is still an open system which allows you to hard modify the system, apps behavior, etc.. So you can set your device especially for your daily use.
For example, the way I set my 2yo-phone gives me 8 to 10 hours SOT, which is faaaar from any Apple devices autonomy..

No it's really mostly just the screen being on. You can test this by setting the device screen to never time out and let it sit. You will notice that it kills the battery.

If Weechat and Whatsapp were responsible for the drains, why don't they show up on battery usage as top drainers?

Bro, you should use an iPhone and see! It's much worse than Android. iPhone have less size batteries and you can hardly get through the entire day with one charge according to your usage. Although apple's implementation of background apps optimization is excellent, but still the battery life is less due to small batteries. I feel android is much better in terms of battery.

Never used Iphone but assumed they have good battery life because of endless praise it gets which is getting old.

That is generic which means apps system api or systems the app uses. Like say the LG tones app. It uses the system BT api and if it drains the battery then all you see is BT at the top.

After years of trial with all sorts of applications to kill apps, battery /juice saves, my ultimate solution on Samsung alpha, 1800amph only battery is conjuction of Greenify, follow up with SD Maid. Alternate day.
Excellent results. I'm rooted.

I'd say that you either have a battery that is past it's useful life, or you have some serious wakelocks going on. 2-2.5 hours SOT is awful. I bought my device used 9 months ago and can easily average 6-8 hours SOT over the course of 48 hours on battery (on stock 7.0 unrooted). I'm only now seeing a lower SOT with this current update to Google Play Services. And even now I still get 5-6 hours SOT in 48 hours.

I know the reason for my bad battery life. It's my signal. Signal here is spotty and if you leave town you lose signal all together. So my device spends most of the day looking for a stronger signal. SOT really doesn't mean much to me.

Ah yeah, well there is that as well. Have you tried turning off LTE and preffering 3G? I've found that helps in some fringe areas.

Yeah I normally keep late off. It doesn't help really. Signal is just too spotty. You can bounce between 2g,3g and lte in 5 min and never move. Then you have the times when the military blocks all GPS and unless you heard the announcement and turned GPS off that would also kill your battery. Then like I said once you leave town you have no signal for hundreds of miles.

Can somebody explain this?

We would need more info before we could really explain it. For starters though it looks like bluetooth is sucking the life out of your battery. Do you have something connected to it currently?
As far as my screen on time goes, im on the pixel rom with no addons and i get 4 hours screen on time

How is 6-8 hours sot possible over 48 hours? I've tried different kernels, lineage/CyanogenMod, Pure Nexus, greenify, and even tried down clocking the CPU to 1.2 GHz or less at all times (shockingly, in normal use I couldn't tell the difference lol). Never got that much screen on time. I'm not even sure airplane mode would do that. My best was around 45 hours, but with about 3 hours of screen on time. And that was with the phone being less than 3 months old.
Currently I'm on stock Android, and getting 20 hours at best with 3 hours sot. At this point, I will say my battery is shot since it is a year old. But I'd love to see your settings and see if I could get close.

Here are screenshots of my battery use from March. 3 days with 6.5 hours SOT. I keep my screen at a relative 20% or so (lower at night). I have very strong signal (major city) And I use wifi about 65-70% of the time. I also actively moderate my screen touches (yes, they do indeed matter). I turn off NFC and I don't use BT. I also actively purge misbehaving apps (I refuse to install some, like Facebook) Other than this, I can't really say. Perhaps, I just lucked out and got a cherry of a system (with the exception of my headphone jack not working with mics...Grrr... and my camera's image stabilization Causing blur at certain shutter speeds)

Mi 9 great battery life

I've had my device for a day now and I was worried at first weather the 3300mah battery would last a day's use and I can gladly say this device is optimised very well.
With 4hours of on screen time with 50% battery left this device has met my expectations and further.
I've hardly come of this phone all day.
So for me it's a thumps up if anyone is worried about battery life it should be perfectly fine for a day+ use.

I've actually so far experienced the opposite today I had under 3 hours SOT and was at around 35%, though I did notice that high accuracy was enabled as well as WiFi scanning.
Will continue to monitor....

Screen on Time is a meaningless figure to judge battery life.
For instance - Browsing the web will drain way more battery life than watching a YouTube video

Th thing is with the MI9 auto brightness is way to aggressive.
If you use lot of outside it will drain lot faster than indoors.
Indoors 6 till 7 hours SOT no problem. Lot of outside 5 till 6 hours or. Something like that.

I've had it on manual
What I have noticed is when I was outdoors, there was some sort of outdoor mode being activated, so not the auto brightness but the automatic contrast. Got it in standard now and so will see how tomorrow on a full charge. Still though, I could swear that colours (the black theme on my SwiftKey keyboard) were adjusting in bright sunlight.
Will indeed keep an eye on this, but yeah so far battery is a let down, and that has been with full 4g signal, Bluetooth off etc

A friend sell his Mi9 after 3 days. With 2 sim cards and 50/50 wifi/lte he get about ~5h SOT without gaming and youtube after <1day.
With Youtube he can get easy 8h SOT but thats normal for Amoled.

Yes that auto contrast setting I have noticed too. Very strange. I can't get it off either.

I'm gonna report it as a bug.
Also as Cell Standby drain is high, I've just adjusted this setting, found here:
https://forum.xda-developers.com/mi-8/how-to/fix-battery-drain-mobile-standby-t3883840/page1

To add at my SOT I use the MI9 in dark mode all the time.

Quick update: seems better already since i changed those settings. Got 30 mins SOT and still at 95%.
Will see how the rest of the day goes!

Hi,
I think something is wrong with the Cell standby usage.
I tried the fix for disabling Chinese antennas, but still it's like this.
https://imgur.com/a/EZD8Xmt
I'm on China version (I bought the mobile in China actually).
Any advice? Shall I switch to Global?
And it looks like that auto brightness seems to consume more battery than manual, is it just for me or something for more people?

I too had the bad drain but switching to LTE/WCDMA helped me so far I think.
I'm at 60% 2 hours SOT and I've been taking lots of photos, such switching that setting helped lots!

My brightness is on auto and seems to adapt pretty well I thought.
WiFi scanning is off.
And I don't have dark mode enabled.
Not much gaming tho but YouTube streaming.
Coming from OnePlus 6t and pixel 3 I'm doing the same things but noticing better battery life so for the 3300mah I think it's doing pretty well indeed I'm very satisfied

I never use auto brightness except when I want to use my phone in full sun (beach..) to activate the boost brightness.
My sot is 6 hours by day. Very good (level of the $9 /$9 plus).

But on the link it said the settings go back after restart of the phone.
Is this not happening with the Mi9?

It does. Hopefully it will get fixed in a future update in GLOBAL roms...

I have just updated to Global 10.2.26.0 ROM from 10.2.24.0 and I'm getting over 9hrs screen on time! I'm getting over 17-20 hrs with that screen on time so I would say it's doing great! I watch a good bit of movies and YouTube on it as well as do a lot of pictures and video. Do I do use it rather hard and get those numbers still!

Im on a PFAEUXM rom, i've found that the battery life is good when you are using the phone, i'm geussing the screen and the CPU are really efficient, but the standby drain when i don't use the phone is pretty bad..

Dude I just got 31hrs with 6hrs and 23 min SOT and I didnt even let it die. I use a lot of photography, video [email protected] I also watch a lot of movies and in-between I do a good bit of YouTube or Twitter.
I can get over 9hrs easy anytime. If I just got for maximum SOT I've passed 11hrs many times and never ran the Mi 9 dead. I mean sometimes it's within a few % but I always put it back on charge if that's the case.
I leave the brightness on auto but it seems I always have to go in the menu and push it higher to my liking.
Now understand this. This is mostly indoors except for when I'm shooting video. I never take it off auto brightness, I just push it up. I have it on increased contrast. Nothing more. I optimize it at least once a day and I clean my Cached file daily. That is the extent of what I do. I have accubattery app on it so I watch to make sure it truly is at 100% before taking it off.
I have no issues with SOT, oh and I always have WiFi on as well.
You say you get 6hrs but only 6hrs SOT with no combined time with it?
