Battery graph - Samsung Galaxy Nexus

Just curious to no if someone has an answer. You see that drop in the graph and then it climbs back up? How can that climb happen without charging. I never plugged it into anything. So how can the line climb back up? Thanks

The graph is an estimation, not 100% accurate. Sometimes when the battery gets warm, the device may think it is a little lower than it actually is. So after using it sometimes if you turn the screen off for a while you can actually "gain percentages".

Charging light

My charge lights have been flashing back and forth from green to orange when I am in the car. What does that mean? Cheap car charger?

Sounds like it. I would try a different one and see if it makes a difference. I bought the cheapest one I could find and I've never had that problem.

sounds to me like a bad connection somewhere
From my past experiences the orange and green flashing light means the device has reached a critical temperature and charging ability has been suspended momentarily until the device reaches a suitable temperature.

Agreed. However, I think we should email HTC on this matter... I would like to know every possible factor of why the light turns green. why it turns red. Also, I would like a change as well.. I would like it if the light didn't stay green while the phone is plugged in and I just get a message. I would like it to blink in some way like 3 fast flashes. or something like that.
Could be temp. I live in AZ. It was 102 today. I think I was charging and surfing a bit. I have never seen my OEM charger do that tho. I will swap back and see

oh after you just said that... IT IS the temp. lol. IN OTHER WORDS. keep the phone cool. can't leave it on a dash or in a car. it will overheat. It has NOTHING to do with the charger.
Keeping anything cool in Arizona, in July, is not easy! I can't walk outside with the phone for five minutes without it getting up to 100+ degrees. If its in the sun for even a minute... Forget it.
It has been over 100 for something like forty days in a row.

Never charging to 100%

Whenever i unplug the phone,the battery drops to 99%. Is it Normal or just me?

Happens to me too. Or if it does hit 100 it drops immediately to 99 the moment i take it off the charger.
Well It happened on my dad's E4GT too. But fascinate/OG Epic/Illusion/Evo 3d Which I own never did so!
Take a glass and fill it up with water until it overflows, think of this as your battery. Tip it just a little and you lose some, at which point you will not have 100% of the water anymore. The moment you take it off the charger, it would only make sense for it to immediately go to 99%

I thought of putting this topic up because i saw how crazy the battery Life is. I put it charge at the time when i was not thinking to put the topic up(for about 2 minutes when the battery was at 32% or so). And thats why it says discharging!

8 hours of on screen time is not reasonable. The percentage is not of the battery time, it's how much battery was used by the display.
He needs to show his on screen time by actually clicking on Screen Display.

Correct, his estimation was simply outrageous. There are many factors that determine how much battery the display consumes. The biggest is the brightness at which the display was at the entire time, 0% brightness obviously last much longer than 100% brightness. Also the types of colors being displayed, dark colors on a OLED display drain less battery than bright colors.

I find ways to have better battery life. Obviously if you have brightness at 100% it will kill battery unless you have a better battery regardless

Again....display on time? People always want to show off the best battery reports but never know how. That screenshot means very little, my guess is your phone was deep sleeping 3/4 that time.

4.2 Daydream and it's effect on battery

Daydream sounds awesome. I have it displaying the clock while it's charging. My questions is, how much drainage is it doing to the battery while the screen is on?
For instance, if i had the screen completely off, I would have reached 100% in 1 hour rather than 1.5 hours since I have day dream working...?
So how much drainage?

What concerns me more than charging rate is screen degradation, AMOLED screens degrade over time so I wouldn't keep my screen on if I wasn't using it

Are any of the daydreams even static? I assumed that the reason the clock bounces around is to avoid things like burn-in.
The standard one is static, some of the third party ones are not. I really wouldn't worry it too much.

Check again, the standard daydream clock is not static, at least the digital one isn't.

Sent from my Galaxy Nexus using Tapatalk 2
it isn't just about burn in... amoled pixels do degrade over time like another user said,and this is a dangerous way to screw up your screen much quicker.
not a good feature to use on our phone imo
It takes a long time for that to happen there are plenty of people still rocking a Galaxy S1 and the screen is fine but I'm not saying there's no one with problems but I doubt it would mess up by using daydream
Sent from my Galaxy Nexus using xda app-developers app
Ya, the digital clock is not static. However, I would worry more about the navigation bar because that thing is gonna stay in landscape mode and I already got a nav bar burn-in in portrait.

depends, is it on overnight? Say you sleep 8 hours that's 8 hours extra the pixels are on per day.
Do the math, it would add up quickly
burn in only occurs when you have an static image in the same place all the time.. daydream move the clock around the screen every few seconds, and with the black background most of the pixels of the screen are off anyway.
so no, there is no danger using daydream.

I'm not talking about burn in....
do you not know about the degradation of amoled pixels over time?
you could end up with dead/stuck pixels a lot earlier than expected.

Self chargine phone?? Hows it possible?

Hello peeps, I was just wondering how can a phone charge on its own?? Im surprised never seen this happen. my brother showed me hes pre paid cricket phone that it was charging without being plugged in. Proof in the video I took.

OK what kind of phone is it and what battery cover is on it. It definitely not gonna charge by itself
TWEAKED 2.0 ELEMENT V3.0 NOTE 3
My phone has done that if I pull it off the charger too fast....drains the battery like crazy
though it IS an ancient phone compared to 2012-2013 gear (Xperia Play R800x)
Is it one of those fake display apps? My brother had one that would show screen being used as solar panel, more light would show more charging current, all fake to amuse others. Or really strong electromagnetic field capable of inducing electricity even from larger distance.
My battery has a habit of charging on it's own.. To an extent. When I reset my phone when the battery is full. It'll boot up with 15% battery, then it'll slowly creep itself up to 20%-25% then it stops. Then again, my battery is going bad.

You must be talking about a different video because the video in the link posted in op does NOT show the back of the phone. He never once flipped the phone over to show the actual back of the phone, so no it does not show the front and back (I have no clue how you landed on that conclusion)! Just for a brief second he tilted his hand (with the phone still lying flat on it's back in his hand) at an angle where you can see the very bottom part of the battery cover, and you can tell it's 2-3 times thicker than the stock S3 battery and door cover so it's obviously a battery case! Sorry to burst your bubble but unfortunately there's no such thing as a magical self charging phone lol

I've seen stuff like that happen with phones before either from a glitch or issues with the battery, and thanks for the reply but I'm no idiot I know there isn't any magical self charging phones but thanks for the input. Have a wonderful day.
