Battery life?

Hi all lucky owners of lg optimus 2x,
I want to ask you a question about battery life of optimus 2x . Is it really better than single cored ones or same, i m not expecting better life really

There's a good review in the optimus 2x forum:
http://www.optimus2x.net/index.php?topic=156.0
Conclusion:
30mn YouTube HD (wifi)LG Optimus 2X: 9% battery​Google Nexus S: 7% battery​30mn Neocore (3D graphics)LG Optimus 2X: 12% battery @ 74FPS​ Google Nexus S: 9% battery @ 54FPS​8hrs of stand-by LG Optimus 2X: 2% battery​ Google Nexus S: 3% battery​

Wow, quite good !!!!!!!!!!!!!!!!!!!!!

I think that test is a bit flawed... PaulOBrien reported that the Nexus S exaggerates it's battery % quite seriously...

You are used o2x. What can you said about battery life of subj? On sleep mode? On used mode?

Here is an interesting test of battery life of the lg o2x.

my battery life blows :/

Well, mine has a pretty good battery....you know now I have time, so I just keep playing with it all day, so with auto-brightness and WiFi always on, playing pretty much all-day I got through 1 day without my charger. Without wifi and less playing I think 2-3 days could be easily achieved.

I am using V10d rom unrooted.
It happended several times now. I need to change SIM cards often as I travelled to different areas during my work. Before I pull out the battery,it is at 50%. After I change SIM card and put back the battery, it drop to less than 17%. It takes me less than a minute to change the SIM card. What happened to the battery??

Use juicedefender

I managed to get 3 days+ out of it under average use. Could probably easily manage 4+ with setCPU or something underclocking the processor and turning off data, etc.

which rom do you use, kernel, what apps do you have running? can you give some infos about your system?
thanks!

Yeah spill the beans i can normally get 20/25 hours on lightish use. Would love to know how to get it to 2 days with room to spare for charging

i'd like to know too. My battery life sucks. Barely make it through a day now. On MCR FR17..

This is one of many threads about this.. But i'll respond anyway.
I had same issue, after some tests, i found out its GSM part of phone thats draining the juice. With airplane mode on it was about 3% in 8h. I was on BlazingDragon, with some apps, normal phone use It lasted 24h on standby without any use, no more.
Yesterday, i tried to flash (lastest for central europe) stock firmware, including baseband, simply i got the phone into factory state. And well, during night with data off it was 1% (yes, you are reading it right, i woke up with phone on 99%), now 10h later with lighter usage (some mp3, not much, a little of tapatalk, gmail push on) i'm at 78%.
I dont have any software except tapatalk installed atm. Dont think my problem with with BlazingDragon rom thou, i suspect some application caused it, but dunno which one
I think it will last 2 days with current usage, and several days with data disabled (using it as plain old phone only for calls )
PS: I dont use any JuiceDefender etc..

Iam using slicks rom, if i only write sms and surf sometimes, i have to charge every third day, but if i playing THD games, i have to charge after 3-4 hours

+1
the stand by time is really nice but gaming sucks out everything from my battery

Other than the battery drain during standby, my current observation is that, say if my battery was at 50% before I pull out the battery (say if I need to change SIM card), after I changed SIM and put the battery within one minute, it suddenly drops to less than 17%. Why the battery loss 33% in no time?
People keep saying that the phone can last a week if it is on airplane mode, or by turning off data 3 days, but then why we need a smartphone of such build?
Has anyone compare the other dual core or tegra2 phones in the market how they perform battery life? Do they have such awful battery drain standby? LG said the battery drain was due to incompatibility of tegra2 and android 2.2. Why sell the phone in the first place? This problem starts from day 1. LG no QC or just want hiding this problem from customer?

it looks like a calibration problem. Either 50% or 17% reading was false.

Just did two full days after reflash with MCR.

[Q] Battery life while gaming?

Hi!
I was just wondering what battery life I can expect when playing android games and using emulators like fpse and n64oid? Wifi off and screen brightness at like 70%. I found battery tests on video playback and browsing, but not gaming. Thanks!

I reckon around 2 to 2.5hours deffinatley no more than 3!, high brightness and high processor usage is a sure way to drain your battery FAST!

Oh, that was not super good lol. I guess I should reconsider picking up a 5000mah external usb charger for 20 dollars on ebay. This phone looks like a really good combination of tablet and phone though, so I think I might get it. Thanks for the answer!

To be fair though when you get the phone youll realise that 70% is quite bright(too bright imo for indoors) I have mine set at 20% most of the time, that'll probably up it to a deffinate 3 hours constant play.
I dont often play games too be honest, I mostly just browse the web and draw a few pictures, i average around 4 to 4.5 hours constant use, I rarely get past 5!

how much big mAh capacity the mini can get?

1500 mAh is the most?
just like to know if there is a factory defaults on this. thanks

As far as i know the real highest capacity battery is Mugen battery for GT-S5570, it has 1400mAh. The stock one has 1200mAh.
Personally, i don't believe in those high-rated fake batteries on eBay, they usually don't have the capacity that is claimed. Maybe there is a better one, but I doubt you need any more than 1400mAh, Galaxy Mini/Pop has small screen and only a 600MHz processor.

good to know
thanks for a detailed answer. i need a bigger one. 1200 not getting me anyway.

Maybe you could save juice by using toggles for WiFi, Data (3G), GPS and display brightnes if you dont. If you're on stock rom you can use power control or widgetsoid widgets, and if youre on Cyanogenmod you can change that in the settings. That gets me by, my battery lasts 2 days sometimes .
Definately give it a try rather than buying a replacement battery!

Might be useful.
I do agree that 1200Mah is no enough for our phone, But we're talking about a low-end phone here which is supposedly not used for a lot of browsing/gaming..etc.
You can save battery by lowering the brightness and turning sync off , it helps a lot.
underclocking will also help if you're not a fan of fluid scrolling and animations.

I pulled out 4 hours of displau runtime on stock CPU frequency. If you actively use your phone for more than 3-4 hours, get a 5Volt voltage regulator and a car battery

3500mAh battery

Hello, I recently purchased the 3500mAh 3.7V extended battery for my dinc. Can someone tell me what voltage I should charge it up to? I am not seeing amazing results, so I believe that my battery is not completely calibrated. I did run it through multiple complete uses (fully charged, to drain, and repeat) so I don't know what the problem could be. Thanks.

What were you expecting for battery life? Depending on the brand it may not be a real 3500mAh battery. One full discharge and recharge should be enough to calibrate the software though Li-Ion batteries have no memory in them. Check this out. It mentions extending the life on the battery but is still interesting stuff.
http://batteryuniversity.com/learn/article/how_to_prolong_lithium_based_batteries.
In fact that whole site has a lot of info on batteries.

Hey tiny. Well, from what I was reading about this battery, users got two full days with heavy usage (they described heavy usage to be streaming music, surfing the Web, testing, playing games, etc.) but, this is what I get, and it's the best I got (3 hours display,half an hour talk time). I even went down to gb to see if it would be good, but I didn't see much of a difference. And I did look at battery university a bit, but I didn't delve into the material. I'll check that link out.

Wow, that's pretty abysmal for a 3500mAh battery, especially in a lower consuming device like the incredible. How does that compare to your stock battery? It should be at least 70-80% better assuming that it's not really a 3500mAh battery. It may be a false claim that it's 3500mAh from the makers. I think 4 hours screen time on 3500mAh should be more reasonable for about 35 hours total time. I usually get about 1-3 hours screen time over a period of 10-30 hours total on my Galaxy Nexus. On my Inc on CM7 with stock battery my usage allowed me to go up to 30 hours, usually 20 on a charge with 30% left I think but it's been a while and I don't know the screen on time. It might have been about 2 hours.

Yeah, that's why I am worried. And actually, my stock battery usually have me like a day with good use. When you put it in perspective, my 1300mAh battery gives me about 67% of the battery life that I get from a 3500 mAh battery. Is there any way I can measure the power of the battery? I take physics, so even finding a way to calculate the current, voltage, and/or resistance of the battery would help.

Check batteryuniversity.com, they have a link for calculating the actual capacity, or if you know your model which you should you can Google for actual capacity. Someone probably has posted capacities of a battery.

just going to add that in my experience(I have 3 Dincs), just a 3500 mah battery isn;t going to give you amazing results on it;s own. power management on the Dinc requires some attention. i find that charging the battery in the phone doesn;t necessarily yield a full charge, especially if you are charging it while the OS is loaded(topping it off). so my strategy has been to run my batteries down to empty,replace with a fresh one and charge them in an external battery charger-but not just any charger but a RAVpower universal charger. I have an "official" Seido charger and that doesn;t charge my batteries fully either even though it thinks it has by showing a green LED. I know some people will say that batteries shouldn;t be treated like this and that they don;t suffer from memory effect so you are free to not do what I am doing.
the biggest things that use up the battery is the 3G radio and the Display so of course if you are just using your phone to do stuff non stop of course you'd be lucky to get 4-6 hours of usage. Even if you have your phone doing useful stuff over wifi like checking for email in the background, it does consume battery. but with my phone in Airplane mode(like overseas where I would have no 3G or Wifi), I;ve gotten a couple of days of Standby time.
other stuff I have done is remove any apks in memory that might be consuming cpu cycles and memory. less is more on a limited platform like the Dinc. biggest cpu hogs on my phone believe it or not is Facebook and Amazon App Store(my guess is that it;s periodically checking my licensing for some apps that I got from them). it;s not uncommon for me to boot up the phone and for the battery to go from 100% to 90% in 5 minutes as the phone is initializing and doing whatever it;s doing. then slowly deplete from from 90% to 80% in 8 hours or so.

Your battery gauge is lying to you (and it's not such a bad thing)

So, I looked through all of battery university, but i still have 1 unanswered question. The website states that most Li-ion batteries should be charged to a mximum voltage of 4.20 V. However, does this apply to all batteries? I mean, my extended battery is a 3.7V battery. Was the htc dinc original battery a 3.7 v battery? If the voltages are different, then wouldn't the 3.7V battery need to be charged to a higher voltage so that the potential difference would equal that of the original battery and thus store the same charge? (theoretically)

You could check wake lock detector on the play store to see what apps may be causing a partial wake lock... I know gmail and uccw cam cause a decent wake lock time

I did check that and I didny find anything very abnormal, since I already greenified those apps.

[Q] Battery consumption N7000

Hello,
I know people have talked again and again about this problem. But I have to ask again because until now I did not found any solution. I have a N7000 and a 7000mah battery (I had in the past a 5000mah battery). My mobile phone looks like a old TV but guess what, the battery holds maximum one day! I have had the problem with all my mobiles in the past (HTC HD2, HTC sensation). I have tried to find the problem by using betterbatterystate with no success. I always turn off bluetooth, GPS and so on. I have installed juice defender ultimate for a long time on my mobile, it makes everything worst. I have really tried too many things, but they all did not help. Is there something that I am missing??? Or is it android?? Is iphone better than that? I am a heavy user but maximum one day with 7000mah?? With the original battery I have to laugh when I look at my battery consumption.
Please give me some new tips. Something that really works. What is wrong with me????

It depends on how you use it....
Most smartphone should have no problem with 48+hrs "standby time"
But in most cases, the only thing that consume the most energy is the display.
I always keep it at the lowest. (only turn on auto while using under sunlight)
I turn off gps, mobile data, wifi. (only turn them on when I need them)
I get around 5 hours (max) with the stock battery. (Screen on time)
But if you are gaming, well you will be lucky if you even get 3 hours.
For games, its depends on how its being code. I have 2D games (Kairosoft games eg. Game Dev Story) which has a greater impact on battery life than a 3D game.
*There are a lot of fake batteries out there, falsely labelling their battery with higher mah. Good battery usually cost $50+.
a 7000mAh should be around $80 (exclude shipping)

Also, a 7000 mAh battery would be three times the size of the original. I honestly believe that the announced 7000 mAh batteries are no where near their announced capacity.
My suggestion would be to buy an original samsung battery. That is what I did and the battery lasts for a day, or for 6-8 hrs with heavy usage.

I dont play any games with the phone. I use it mostly to call or chat or browse. Regarding the fake battery you are may be right. It costs only about 15 $. I have switched back to the original battery but still, it does not look good. I still dont know what is wrong with my n7000

I have checked the healthy of the original battery with some apps and they show all "good healthy". Should I still buy another one? How long is the life time of the original battery?

never trust an app to tell you how your battery are doing.
I would recommend you to buy an original Samsung battery. They have a life span of several years, but should be changed after one year as the capacity deteriorates.

buy a new battery, your battery maybe dying
make sure you get the real thing though.
Do some digging before making any purchase.
