My battery is crap too sometimes is ok ..

but it is just screen what drains .. and + if u browsing internet and u have flash enabled it is big drainer added .. needs more cpu power..

if u put mobile on eco mode turn down screen to 25%-30% turn all radios off u should be fine

download apps like battery calibration . or battery stats or juice defender
[LG Optimus G (International)] szaboagoston:
I'm really not an expert at this. I have also just opened my Optimus G, so I can't share my personal experience with this phone. However, the battery of my Lumia 920 needed around a week to function properly. The first three days I got heating and drain, almost 10% per hour, but now the phone lasts easily for two days with light usage. I was looking everywhere on different forums for hidden factors draining the battery, until I found a comment, where someone described this phenomenon: he said that a battery needs around 12 full cycles of drain and full recharge before optimal performance can be obtained. So from now on I will be more patient.

Then again, I'm new here, so other opinions are welcome. :)
[LG Optimus G (International)] iEthos:
eeemm that is not true i had phones over years and batt been always same..

it is all about usage ..

jut do test charge it fully and dont do nothing with it just ocasional phone calls and sms's and ull see then..
[LG Optimus G (International)] scoobydooby:
For me on jb v03 I get around 18-19 hours with around 3 hours screen time, but agree its all about usage.

I mean if you leave your phone off most of the day with your wifi and data turned off it will drain very slowly..

I find the biggest drain is always screen, cellular connection especially when you have poor signal, and wakelocks.
[LG Optimus G (International)] NickereN2O:
I had same xperience with my iPhone 5 so I hope its the same with my LG.

But for know I've installed JuiceDefender and disabled LTE (HSDAP+ i fast enough for my needs on the phone anyway) ;)
[LG Optimus G (International)] iEthos:
exactly this is my problem ..

we traveling to the places while am in work and there are areas where is poor signal or no signal that means phone automaticaly boost its signal which is very big drain and if your mobile has no signal at all and u obviously set to automatic search it searching searching and draining hell lot!

---------- Post added at 09:09 AM ---------- Previous post was at 09:07 AM ----------

this is true as well 4g signal is even stronger signal as previous 2g 3g drains so much plus when u surfing on the net!

when 4g will be standard the manufs will have to make new generation of batteries to stay last longer o LTE..

Phone idle is draining battery for me. Any suggestions?

https://www.dropbox.com/s/k7bi3x4r8gk80pn/2013-04-15-09-44-47.jpg

I've already installed most of "LG" apps that were preinstalled on the phone.

Phone idle 28%

Screen 17%

Cell standby 17%
[LG Optimus G (International)] n7lbk:
Phone idle refers to the amount of battery cell radios are using up when the phone is sleeping. I would recommend moving to an area with better reception and disabling data when unneeded.

[AT&T Samsung Galaxy Note I717] testerman123:
I was wondering if anyone has had any luck changing the band on any of the 4.2.2-based roms?

to be sure, i mean making the band "3g" only by dialing *#*#2263#*#* and then changing the band.

In all the 4.2.2 based roms i have tried, trying to go into service mode by any means results in an empty service mode screen with no options to select from.

my need to change the band is so that i can get out of the perpetual "H" or "H+" mode that eats my battery like no tomorrow.
[AT&T Samsung Galaxy Note I717] gregsarg:
If you are using the ATT network, then I'm afraid you are stuck with the automatic band selection you are seeing now.

ATT networks are RAT restricted for this generation of device, and manual band changes cannot be made, regardless of the ROM you are using.

How nice it would be to drop back to an edge 2g connection at work and enjoy the battery life, like I could only 1 year ago using my inspire 4g, But the note will not allow it on this network.

Several other networks are able to change at will.......(C'mon ATT !! Seriously ??)........sorry......g
[AT&T Samsung Galaxy Note I717] chicanowpride:
The Collective Room has a 4g(I think modem)on it works good but I like Rootbox better not 4g do http://d-h.st/TYO or look around cheers!!!!!!!!
[AT&T Samsung Galaxy Note I717] rangercaptain:
Its screen time/ brightness that eats battery. Why would H to H+ affect the battery? That change is an indicator of signal strength/distance to tower not what your modem is doing.
[AT&T Samsung Galaxy Note I717] Demmonnixx:
That's what I was thinking. Kind of noob around here and with this whole rooted and rom thing but I'm liking it. Haven't had alot of time to search around but is there a way to change the screen time? i know the brightness yes but wasn't sure about screen time. Sorry if a stupid que:confused:stion
[AT&T Samsung Galaxy Note I717] rangercaptain:
Change screen time by using screen less.:(

Less brightness is easy using the slider on the status bar.
[AT&T Samsung Galaxy Note I717] testerman123:
While i agree that screen time has a lot to do with this, i am talking about battery being eaten away without the screen being on - like 6%-12% drain per hour range. This is probably network related. For example, in my tests, keeping the radio on an LTE band would induce such battery drains. For comparative purposes, on the blackstar xi rom i was on before, battery drain was ~1.5% per hour range when screen off.

Just in case someone is wondering, these numbers are based on fresh installs (after full wipes x2) of several of the latest 4.2.2 roms (the latest (3/13, i think) collective rom included). the brightness is set around the 10% range. and the percentages are taken after the rom has had a chance to "settle down" (i.e. maybe 5-6 hours into it).

Also, in case someone was wondering, i have tried resetting the battery stats when installing a couple of roms (although this should be a non-issue) without any effect on the battery life.

Furthermore, there is a preponderance of evidence to support the 3g/H/H+ battery saving method (for quick summary, google *#301279#)

gregsarg - im on bell network in Canada.

Thanks for your comments so far, guys. keep 'em coming.

Also, it would be great if you guys could share some of your battery drain experiences with the new 4.2.2 roms. Perhaps stating the rom name/version, whether data is always on, and any battery saving apps/tips/tricks used?

Edit: Another thought is CPU usage - and ive tried underclocking, trying diff kernels and governors just to get marginal benefits.
[AT&T Samsung Galaxy Note I717] testerman123:
hello? bump :)
[AT&T Samsung Galaxy Note I717] Agoattamer:
What baseband are you using? Try installing a Canadian ICS baseband/modem and see if that allows you to change your bands. They are not locked like ATT modems.
[AT&T Samsung Galaxy Note I717] testerman123:
Uclf6.. I think that's the att one.

Latest Canadian ICS modem i could find was Uclf4. Let me try that.

Is the latest ucmb (sp?) Modem locked too?

Actually, i also wanted to find what sort of drain are others seeing with data on, screen off?
[AT&T Samsung Galaxy Note I717] rangercaptain:
Any modem that was released with at&t ROMs will be restricted. Canadian released modems or the Singapore ROM modem should allow band switching.
[AT&T Samsung Galaxy Note I717] Agoattamer:
Latest Canadian modems can be downloaded from here:

[AT&T Samsung Galaxy Note I717] testerman123:
Thanks Agoattamer and rangercaptain. I tried MUGLF4 since im on bell - still no dice with the band menu.

*#*#BAND#*#* shows up as a blank screen.

*#*#DATA#*#* > Phone information > [MENU] > "select radio band" shows a blank box as well.

any other ideas? maybe its a rom thing..
[AT&T Samsung Galaxy Note I717] rangercaptain:
The ROM has the menu selectable band "Use 2G network only", so I think its a modem thing. I used an older Bell modem last year, and it had the service menu unrestricted.

[MDA II, XDA II, 2060 General] Steve from down under:
3G in Australia/NZ is the "3" network from Hutchison which is basically UMTS so not compatible with the XDA which is GSM/GPRS

I noticed some people on eBay selling XDAs saying that they are 3G compatible but the smallprint read" on the 2G network" or something similar ie their fallback GSM network.

Cheers

[Nexus One Q&A, Help & Troubleshooting] viditbhargava:
I have the stock microSD card that came with the Nexus One (4gb class 2) and I am looking to replace it with a higher capacity and higher class microSD card.

I am looking at a 16gb class 10 microSD card for this purpose. Will this be compatible with the Nexus One?

AFAIK class 10 cards are SDHC cards. Does Nexus One recognize SDHC cards?

I have read some compatibility issues with a 32gb class 10 card, but not 16gb class 10 card.

Also, I will be partitioning 4gb with EXT4 file system (for mount2sd reverse mount) and the rest FAT32 for normal use. Will class 10 card work with both these file formats and will mount2sd work?

Or would a class 6 card be better for speed and compatibility?

Thanks for helping.

[Galaxy S 4 Q&A, Help & Troubleshooting] cell128:
I though samoled used more battery than other screens.
[Galaxy S 4 Q&A, Help & Troubleshooting] thachosenone:
Wrong, considering that samoled's blacks are actually pixels that are turned off and using no power. Why do you think htc's are known for not lasting past 8-10 hrs, since they have lcd panels.

With the s4's new phosphorous based amoled screen, it's supposedly going to provide 40% improved battery efficiency.
[Galaxy S 4 Q&A, Help & Troubleshooting] Dannyada1988:
Although the battery efficiency is improved, but owing to the Full HD display, the battery will be used for more, so the battery life should make no much difference compared to S3.
[Galaxy S 4 Q&A, Help & Troubleshooting] _delice_doluca_:
I believe it always makes difference. For example in this case there are 2 green sub-pixels for every red and blue pixels. So the number of the green pixels are = 1920x1080. However the number of the red or blue sub-pixels are 1920x1080/2. At this Ppi this can not bother anyone with naked eye but the process of the picture getting created on the screen bothers me. First the GPU draws the picture, then calculates the colors to fit in to a 1080p screen and the image is sent to the screen. Because the digital data of the picture is calculated indepedently from the sub-pixel arrengement, it only contains the colors. Then this whole process starts again to try to fit it to the pentile screen. The green sub-pixel number is equal to the "actual" resolution and they are used as base and then the blue and the red sub-pixels are barrowed from left, right, up or down according to the needs. Too much bother to create an "actually-not-a-1080p-picture" because only the green sub-pixels are really 1080p.

So every time I think about it I want to ask "why they don't just skip trying to sell numbers and put a high burden on the GPU for only one color of sub-pixels, and just make a lower resolution screen with every sub-pixel arrengement and make it perfect". It is a screen just as big as my palm. No need to push the pixels above where the technology could make its magic to the colors, brigthness, sharpness etc.. Because the smaller and more LEDs mean the harder work to do for both GPU and the manufacturer.

AMOLED "can" use more battery than other screens on equal brightness. Novadays Samsung prefers to make AMOLED screens highly sun-light resistant so they can reduce the brightness and still give enough visibility under direct sun light, and pentile arrengement is also lowers the cunsumption because the screen doesn't have the pixel number they tell in real life. The the real economy comes when the screen is partially or completely black. Because -unlike any other screen technology- AMOLED uses zero energy to produce blacks.
[Galaxy S 4 Q&A, Help & Troubleshooting] BarryH_GEG:
One of the most important updates that the Samsung Galaxy S4 brings is the new 5" Super AMOLED screen of 1080p resolution. While it does have a PenTile matrix, the 441 ppi pixel density makes sure you won't be able to spot the hated cross-hatch pattern. The defect wasn't easily spotted on the Galaxy S III either unless you looked from a closer-than-comfortable distance, which is to say it was as good as invisible to the naked eye. The design of the PenTile matrix has been changed too, so now green sub-pixels are twice as many as blue and red sub-pixels and the arrangement is changed.

This however matters little to anyone not armed with a microscope

. What you should take away from all this is that

the final weak point of the Super AMOLED screens has been taken care of and the Galaxy S4 offers image quality like no other smartphone on the market.

Its impressive contrast and almost perfect viewing angles make everything on the screen pop-up regardless of your view point. The 5" 1080p Super AMOLED display is gorgeous. The color saturation is beyond the reach of any LCD out there, which make even the dullest image appear remarkably vibrant. Still, if you are not a fan of the oversaturated look of the AMOLEDs Samsung gives you the option to tune down the saturation to more natural levels and enjoy the best of both worlds. The brightness levels of the Samsung Galaxy S4 is slightly higher than the rest of the company's AMOLED displays, which is to say not very high. However, due to the low reflectivity this doesn't affect outdoor performance.​

[Galaxy S 4 Q&A, Help & Troubleshooting] Toss3:
They only added a green subpixel pholed(had red one before), so basically it should results in a 25% decrease. Combined with the increased amount of pixels and decreased subpixels(diamond matrix), my guess is that it is more or less equal to an lcd at the same resolution(except when displaying whites).
[Galaxy S 4 Q&A, Help & Troubleshooting] thachosenone:
Another thing to consider is how replaceable the glass on the screen is. The drawback with amoled panels is that most panels have the screen and digitizer glass fused together.

Although I think you can replace the glass on a gs3. But most amoled panels I've seen have them fused together, so replacement is a pain.

Luckily, I have not cracked a screen of the 3 phones I have (2 tmo vibrants, maguro gnex). *knock on wood*

How many of you have LCD TVs? How many of you are so concerned about color accuracy that you pay to have them professionally calibrated? Colors are exaggerated in SAMOLED. 100MM people have purchased Galaxy devices with SAMOLED displays over other devices with LCD panels that likely had more accurate colors. Conclusion: either the masses like exaggerated colors, they don't care, or they just buy what looks good to them.

And the One's display is way off compared to previous HTC LCD displays in both color accuracy and temperature so the inaccuarcy of SAMOLED is hard argument to make. In comparison to the One at least.
