Battery problem

I recently bought atrix 2 and found that it shows battery in the intervals of 10% so i installed battery solo widget and also circle battery widget which indicates 1% battery discharging. But whenever i unplug the charger after it is displayed 100 in the widget, the widget shows 99 as soon as i unplug the charger.. Is there a problem in my battery???

I picked up this tablet not knowing there is zero community backing. The radio is locked to Rogers and the OS on it is 3.01, v905r-10c baseband. Are there any guides to install newest software? 3.1? The t-Mobile update is only available in US. Only way possible I think is with .kdz file but I've yet to come across one. Help? Input?
[Upgrading, Modifying and Unlocking] drezman:
Well, there is a bit of development still going on at the rootzwiki site

http://rootzwiki.com/forum/125-lg-g-slate-development/

I also have a rogers v905r but I flashed the t-mobile ota update about a year ago and it ended up screwing up my 3g radio. Since then I believe that they've made a cm10 rom that is flashable without overwriting the radio partition.

Also, if you'd be able/willing to make a copy of your stock v905r baseband it might be the break all of us other v905r users with broken 3g have been waiting for!

Hello my name is Jonathan and I'm currently on HTC EVO 3d this will be the last nite with it beacouse I'm purchasing galaxy nexus tomorrow from this guy on craigslist for 200 usd .so I was just wondering does the this phone can be flashed to cricker or boost mobile or any other phone provider that doesnt required a contract ? and do tall think is a good price for a good condition used phone ? Thanks
[Samsung Galaxy Nexus] thebobp:
Make sure it's the unlocked GSM version, which can be used with any GSM provider. The CDMA versions are locked to their respective provider, as far as I know.
[Samsung Galaxy Nexus] martonikaj:
If it's an i9250, which is unlocked and GSM, you can use it with any prepaid GSM carrier like Straight Talk, T-Mobile, etc. etc. etc. These models don't have any branding on the back, so it just says "Google" and "Samsung". Although I'd be wary of buying it unless he has an active SIM to test in it to make sure everything's OK.

If it's a Sprint or Verizon model, don't bother with buying it to try and flash it to another prepaid CDMA carrier. Just buy a GSM model.

Did your device update? Check the version.

If it did, you likely lost root access as well as the functionality of any system apps that are not part of stock (google play qualifies here).

I have the same problem but the installed applications are still there.

This might be the scenario, since Android Market comes with the Rom it was overwritten by Google Play

I have used google play once but now its not there anymore. how do you put it back? Anyone?

What application did you used in performing such test? You can overclock the gpu and cpu for better results. And also..turn off the power saving mode before benchmarking because it affects the result.
[Galaxy S III Q&A, Help & Troubleshooting] d4fseeker:

So I changed ROMs and forgot to wipe the secure element so I went on googles site and reset my device that way.

It said it couldn't do it so I restored a backup with wallet already configured.

And my device is still not reset according to google. Did I **** up?

[General Questions and Answers] yzak58:
So currently these 3 types of display techs(mainly their variants like Super AMOLED, Super Clear LCD, Super IPS LCD, LED Backlit LCD,IPS TFT etc) are the main kinds of display technologies which can be seen on the latest phones.

I have a few doubts regarding this topic.

1- Which technology gives the best color reproduction?

I know AMOLED sucks at this field.What about Super IPS n LED Backlit LCDs n TFTs?

2-Which one has the best viewing angle?

3-What is all this pentile matrix stuff about AMOLED Displays? :confused:

4-Longevity,which one lasts long without noticeable degradation?

5-One technologies main advantages/disadvantages over another
[General Questions and Answers] tlawiv:
1 amoled has very good contrast. but pixel density also important. Phone could have anyone of these displays and have varying dpi

2 IPS has the best viewing angle

3 i heard of that I've have to google it.

4. Longevity has too many variables. depends on use quality and always random dud phones so idk.

5. depends on what you want it for reading vs watching video the size of the screen quality of a product. you can get knockoff iphone with rentina like display doesn't mean cheap phone will last longer then a lessor display. It's more of a personal choice than an overall one better than another.
[General Questions and Answers] speedyink:
1. Depends if you're looking for real life looking colors or bright, vibrant colors. Out of the box AMOLED is the latter, while all LCD's are the former. However, all these screens can be adjusted (Android phones anyways), so it's not such a huge issue.

2. IPS LCD has the best viewing angle, but AMOLED is so close behind it's not a deal breaker. All other LCD's would be behind them, but the amount of which depends on the quality of the panel. iPod Touch viewing angle is terrible, while Xperia Play's is amazing for an LCD.

3. Pentile is just a different sub pixel arrangment. It can apply to LCD or AMOLED, it's just seen more on AMOLED's because it makes those displays last longer. Pentile screens don't look quite as crisp as RGB layout screens, but it's harder to notice with the 720p displays out there now.

4. Traditionally AMOLED doesn't last as long as LCD, but it seems to be panel specific. Some AMOLED panels can last really long. All in all you shouldn't see issues within a 3 year phone contract with either.

5. Totally personal preference. I like AMOLED's myself, mainly for the infinite black levels, vibrant colors, and very good viewing angles. Some people like LCD's because the colors out of the box are more natural. Also some like how there are 720p RGB layout LCD's on phones. AMOLED hasn't been able to do this yet, it has to resort to pentile for those resolutions. Then again, it's hard to notice at ~320 PPI

How about super amoled?:confused:
[General Questions and Answers] Rick_1995:
Personally i seem to prefer SLCD over SAMOLED, the whites are bluish and there's a weird hue in all colors except black in amoled, not sure why but the blacks are true blacks which is not the case in lcd where all colors are perfect except black is kind of grayish because of the back light.

My AMOLED colors were slightly off when I got my phone (a little on the warm side). With a quick color tweak the colors look amazing now, along with the true blacks.
[General Questions and Answers] Allanitomwesh:
Super Amoled Plus and super LCD are the higher end panels and bring out the best of each technology. However nothing beats a good ips panel in my books. The colors are flawless, and the viewing angles impeccable. That is all I need.
[General Questions and Answers] yzak58:
AMOLEDs provide true black because in this technology, each pixels produce its own light(unlike LCDs,in which a single lightsource illuminates the entire screen). And when black is needed to be produced,that individual pixel is completely shut down,thus zero light is emitted.Hence true black.

[General Questions and Answers] Martin L.:
amoled is much more colourful than the others.

A I-Phone 4 looks really pale beside a Galaxy S or a Galaxy S2.

Amoled has limited life-time and looses brightness.

The power consumption is dependent extremly on the brightness of the colour.
[General Questions and Answers] SharpnShiny:
Power consumption is EXACTLY what interests me most about this. I remember reading a couple of years ago that Sony Walkmans using OLEDs offered vibrant colours while using far less power than LCDs. The trouble is I'm having trouble finding more information on this now that I'm looking at OLEDs in smartphones. Is this true, does OLED use less power, does it not use a backlight like LCD?

I'm dying to know because I bought a cool phone a few months ago, but hadn't learned about battery usage/capacity and now I HATE the phone for it. I'm looking at the OLEDs e.g. on the Motorola RAZRs (with 2000 mAh batteries) and I'm curious about them.

UPDATE: I just found a simple document composed from companies and organisations involved in OLED production which, they say is designed to eradicte myths on this. You can see the document here, and on power consumption, my brief understanding is this:

LCD: uses maximum power to display any image

OLED: uses minimal power on darker images, maximum power on brighter/whiter/colourful images - white/very bright images use more power than LCDs

This leads me to think that switching to OLED can only result in at least some benefit in battery life, no? I think most of us on Android are conscious of the use of black and white in the UI, wallpapers etc. so something like this would help. Is it a significant benefit? A backlight on a TV plugged into the wall is fine, on a smartphone I can see why it's a battery-killer. I note the caveat about OLEDs using more power for white and very bright images, but the way I see it, unless you're using a white wallpaper, this isn't an issue. I speculate a power saving when all is accounted for.

So, if a TFT display is considered not quite as good as an AMOLED or an SLDC…how could a difference be noticed between the Xperia Z’s TFT display, the SGS4’s AMOLED and the HTC Butterfly’s SLDC3 – all 5 inches, all 1920x1080? Battery life/colour reproduction/daylight visibility?

Thanks for the input.
[General Questions and Answers] dreis911:
decision

I'm sorry for breakin' in this late, but... I hope to help in the future decisions.

We're mixing some things here:

LCD is a technology. AMOLED is another technology.

TFT is a sub technology that must be applied under one of the mentioned before.

TFT is an array used to feed large displays (a mobile phone is already a large display).

Since phone displays are "large" either LCD or AMOLED need an active controller to maintain brightness in each pixel.

This is A BIG difference between OLED (PMOLED) and AMOLED.

As SharpnShiny mentioned mp3 players/walkmans (small displays) can use OLED which use much lesser power than AMOLED.

In OLED/AMOLED displays each pixel produces it's own light, which can be a good power saving if most of the image is black or dark, because, in black the pixel just doesn't light up.

In LCD there's permanently (monitor ON) a "backlight". Even if the image is black! What the display does is block the backlight when it needs black.

About power consumption in either cases... I don't think there's a really noticeable difference because it depends a lot on the usage!

UPDATE: Sometimes the best way to save battery is to tweak several settings (including the Kernel) as the display brightness levels and thresholds.
[General Questions and Answers] gravityng:
Thanks! That's what I intend to say. It seems many people misunderstanding about TFT.

TFT is not a panel technology in comparison with TN, MVA, IPS, PLS, AVS, AMOLED,....

In other hand, Led-backlit is a similar case, it is a type of backlight, cause the LCD need the illumination. And there are 2 kind of LED, Edge and full-array. In mobile, almost is edge-led because of low cost and thickness. Full-array Led backlit only appear in several high-end TV models. The older tech is CCFL, which consumes more power

It means that a new LCD display which uses IPS panel also include a TFT layer and an edgeLed-backlit.

Sorry if any typo mistake. My bad English :D
[General Questions and Answers] SharpnShiny:
Does anyone here know much about SAMOLED? I read in a phone review that it's more a marketing term than actual performance difference over AMOLED, but I'd prefer to double check that. For anyone who hasn't seen that term, the S is for Super (don't laugh yet!). I think the Motorola RAZR i and the Samsung Galaxy S III Mini are using SAMOLEDs.

I've been comparing my new and old phone screens when considering this thread. I have to say I prefer the TFT LCD screen more than anything. Even with a lower resolution, the images (video and static) is beautiful to me. My RAZR i has a higher resolution but a pentile matrix SAMOLED. It reminds me of phones 5 years ago, the matrix gives the impression of cheap pixel displays in my opinion - but I keep reading it's amongst the most battery-saving screens in the mainstream smartphone market and for that I am greatful.
[General Questions and Answers] Pennycake:
I get noticeable battery drain difference by turning down the brightness on my AMOLED screen.

Decreased brightness also extends the life of the display.
[General Questions and Answers] dreis911:
good work

Yes. SAMOLED is the Super AMOLED from Samsung.

I wouldn't dare to say that it's just a marketing stuff... Because it's a little about "sub-pixels" and their layout. I would say thay the AMOLED technology is there with Samsung's engineering so that picture could get better.

That's what I meant in my last post, under the UPDATE statement. Also try to tweak your phone's clock (if you haven't done it yet).

Mine (a poor 600MHz ZTE Blade) is working from 245MHz to about 650MHz depending on the load (from underclock to overclock).

[General Questions and Answers] yzak58:
AMOLED is getting better

S4's AMOLED screen gives a color reproduction close to HTC One's screen.

Its way better than Xperia Z's
[General Questions and Answers] lkashl:
From my understanding (which may not be entirely correct, feel free to contribute):

AMOLEDS: Typically have better blacks since no pixels are lit to display black but have tinted whites (generally not visible unless compared to an LCD). They consume less power than LCD's during black since no pixels are lit and significantly more during white and bright colours. Depending on the colour being reproduced power draw may vary greatly (LCD's remain constant), greens consuming the least, blues consume the most and reds fall in between but weigh towards less power draw. They also tend to suffer from burn in.

Some are pentile displays (displays without a "plus" prefix/suffix) which means they're less sharp due to a pentile arrangement (which is cheaper to manufacture and reduces blue aging). Comparing an AMOLED's PPI to a rival LCD is misleading if its a pentile display and where PPI counts are equivalent the LCD will look superior. AMOLED's also have inferior colour reproduction and unequal saturation but many consider this a bonus of AMOLED displays.

LCD/TFT: Rely on persistent backlighting and therefore struggle to achieve pure blacks. The whites are purer than AMOLED's and consume significantly less power. Colour reproduction is truer and brightness is also generally higher and more power efficient. Typically have inferior viewing angles to AMOLED's. Many LCD's use polarised filters to block out the backlight leading to better blacks however the trade off is a sacrifice in viewing angle. Cheaper displays may suffer from back light bleeding. On non dark imagery LCD's are less power efficient than AMOLED's however they are better on light imagery. Tend to show motion blur.

Those are some of the disadvantages/advantages, I'm sure I would have missed some, but really it comes down to a preference thing and varies depending on who manufactured the displays. As a general rule though, AMOLED: higher power consumption, better blacks, oversaturated, less motion blur. LCD: lower power consumption, better whites, more motion blur, less viewing angle.

Also as a note, samsung are pushing AMOLED tech in terms of power efficiency and will hopefully eventually match LCD's.
