Develop Bugs

[REQUEST] Infrared mode patch.

Can a dev please make a patch implementing this app/script/hack. The Inc has a red theme so I may be willing to go with a red display if it truly doubles battery time. I read something about adding an option to the developer app. Being able to turn it on and off would be ideal.
Thank you all in advance,

I would also be interested in something like this, if it can give me longer battery life.

Ehh if youre really desperate for battery life why not just do the recalibration trick? I'd rather have the battery run out quicker then have the phone look like that anyway.

The thing i don't get about this is they claim it can give your phone double your battery. Wouldn't the only thing this effect is the draw from the screen? I mean we already went from the lcd screens to the amoled screens and they are supposed to use alot less power and i haven't noticed any difference. My screen is only like 5% of my battery draw also....

this is correct. it won't make our batteries last twice as long, but it may reduce the power used by the display by about half. our display is not a battery hog to begin with. AMOLED is more power efficient than lcd 3/4's of the time. the only time AMOLED draws more power is on an all white or mostly white screen. this is why the web browser appears to kill the battery so fast.

I think that's a reporting bug with the stock Incredible ROM, because screen shots from a Nexus One show the screen being far and away the largest power draw. Flashing my Incredible to CyanogenMod also showed the screen as a large power draw (75% or higher). I didn't notice any appreciable difference in battery life either.

I had similar results using the yeti rom. Display was always in the fifties or higher.

I'd rather not use my phone at all if I had to use it with that red tint. I understand someone using this to test but why would you want to use this all the time? If you need more battery, go buy a new one. Turning this on defeats the whole purpose of having such a nice phone and screen. It's like buying a V8 and disabling 4 cylinders to save gas.

I can see how it would be useful to toggle on in certain situations (emergencies, etc). The amber tint didn't seem quite as hard to look at as the red did.

Yeah, I'm quite sure that number/percentage is a weighted average. That's why "cell standby" appears so high, I think each one of those categories could be duty cycle or total percentage of potential power drain, such as 65ma/120ma= 55%, although it's obvious that the display will be one of the major drains -- it's always "on" unless the screen is fully asleep or the phone is off--let's not forget the backlight, which is totally independent of pixel intensity/color's specific power draw.

I'd like this as well, if only because the lowest brightness is pretty bright to my eyes in complete darkness!

I am really interested in seeing this on the incredible.
I am an amateur astronomer, and the night vision mode would be really nice to have.

We may have AMOLED screens but soon there will be a ton a people with LCD screens... remember the switch because of the screen shortage?
Granted I probably wouldn't use it much... it'd be more of a novelty for me.

Display, regardless of brightness, uses >60% of battery at all times

Regardless of what I have the brightness to, it seems display always uses the majority of my battery. For example, I recently flashed G-Lite and fully charged one night, set the display to about 30%, and left my phone idle overnight. In the morning (after about 8 hours) the battery was at 40% and display counted for 60%. The screen was definitely off. I had the phone on the stand next to my bed .
The G2s poor battery life really bugs me, especially after finding out how my GFs iPhone 4 lasts 20+ hours with heavy use.

You mean that the display accounted for 60% of the 60% power lost over night, right?
My opinion? Wipe and reflash if you can. Sounds like a weird random error. Are you running G-Lite 2.0.1, the latest version?

Correct. I am indeed running version 2.0.1.

Setting brightness won't mean much when it comes to battery life because our screens, unlike AMOLEDs drain the same amounts of power regardless of how bright or dark colors are displayed.
I'll have to agree with captainreynolds, try to reflash if you can. If that doesn't work you may have issues with the battery. Battery life is not entirely an issue with the G2, but with android itself, which tends to use more battery when compared to other mobile phone OS's.
Although, I still manage to go through a day with the battery with heavy overclocking (1,6GHz) and above-moderate usage.

Superwiped, reflashed, and still the same problem. Today I had the brightness turned down to probably 10% and after unplugging my phone lasted 5 hours. Display was 64% of the drain (40 mins on).

The g2 can have good battery life, first thing is your battery having these issues no matter what rom? Have you tried flashing a diffrent radio? Does you girlfriends iphone allow her to buy a new battery from ebay for a few bucks and install it herself with out any trouble?

Iphone heavy use for 20+ hours?? With blutooth, wifi, games, txt, videos, web browsing?? Heavy the whole time? I think not. I'm not an android fanboy or anything but that's a lil off.
As far as battery life does it do the same thing on every rom you try no matter what?
Sent from my HTC Vision using xda premium

This is so annoying. I call Tmobile and they claim 4.5 hours is normal for the G2. On top of that, I can't get a replacement even though I have insurance because it isn't broken, despite the fact that the display is draining an alarming amount of power from two different batteries, regardless of brightness (yes, I have set it to 0% brightness and it only makes a few percent difference on display consumption).

so do you know what radio your on and have you tried changing to a different one?
try typing *#*#4636#*#* into the dialer change settings to gsm only. i know your problem is with display but just curious what affect this has on your battery

Are you running a custom rom? If so you could try flashing back to stock froyo then see how your battery life pans out, or u could unroot then root again.
If worse comes to worst I can recommend an extended battery for better battery life.

Could re-rooting fix it? I've been rooted since I got the phone in Dec '10

You are confusing the brightness (%) with what colors are displayed. The brightness absolutely affects battery life, as I can get up to 30% more time between charges by going from "Auto" to 35 or 40%.
What you are thinking about is the actual colors displayed, such as black versus white. On an AMOLED screen, displaying lighter colors consumes more power than than darker ones. So having dark wallpapers and interface screens can actually help with battery life. Maybe one of the reasons that the AOSP Android theming uses so much black?
With LCD type screens, the color makes no difference. The same amount of backlighting is being used regardless of whether the screen color is black or white. This is completely independent of the brightness %. So you can be displaying black, and still have the brightness at 100%.

Rooting is just giving SU permissions. Just giving yourself SU permissions again shouldn't change anything.

i too have this problem. i have read somewhere, a topic on xda, saying that its the connectors and flex cables in the phone. something about wear spots on the flex cable makes the plastic rub off and you end up seeing bare metal on the cables.
try sliding out your keyboard half way, and look at the flex cable. do you see any of the metal hanging out?

[Q] Horrible Battery Life

How is everyone finding the battery life. Personally, I am finding it just plain horrible. I'm not sure what the issue is specifically but either something is draining it or it is just really that bad, in which case I will return it. I can't get a day's worth of moderate use out of it. It seems to be at most half of what I get from my note 10.1 and they aren't set up any differently. I've tried some of the basics like turning down the screen brightness (which annoys me), turning off the smart stay (but why have a feature you can't use), tweaking email checking settings, turning off samsung sync, turning off bluetooth (don't use it), and locations services. Is anyone else seeing this as an issue and does anyone have any additional suggestions for me to try?
Thanks in Advance

I get about two days between charges on mine. I get a decent amount of usage on a daily basis between email, Facebook, and candy crush. I even have Google Now running. How many charge cycles have you been through?

If by charge cycles you mean fully discharging the phone until it shuts off, I haven't done that, but could give it a shot. It has gone down to 10% several times though.

No battery problems here. I wouldn't blame charge cycles, if they have any effect at all, it is minor. If I were you, I would do a factory reset, followed by an exchange if the reset doesn't fix it.
I have smart stay on , backlight on auto, and take no extra precautions for battery savings.

Can you please post some screen shots of your battery life at the end of a typical cycle? It will help with comparisons by giving us more details on your running apps, screen-on display times, etc. Also, what wakelocks do you have? Use BetterBatteryStats or Wakelock Detector from the Play store for that. This info might help us to identify just how much drain is related to rogue apps or the general battery life itself.

Thanks. Just downloaded BetterBatteryStatus. I'll let it run for a bit and see what comes up. I'll post what I came up with with screen shots from it. Thanks for pointing me in a direction.

Also, it'd help to know how many hours "just plain horrible" is.
I'm not delighted by the battery life I'm seeing, I'm finding I want to charge every night, and that I can easily consume 15% / hour or more even without the screen turned up past 20-25%. (watching video off the NAS in the house.)
Then again, this is the first LCD display I've been able to read in full sunlight, and that's remarkable to me. I often wind up with full sun in the morning when I get up, and am delighted that if I did charge overnight I can use the device even then.

The battery needs some initial "training".
Charge fully on the first and run it all the way down to nearly zero, and fully charge again.
DO NOT interrupt the initial charge.

Battery life is great here after 5 cycles running it to 1% and recharging full at first it was draining faster but now I can watch 4 hours of netflix and still have 25% left nice thing is that the battery charges superfast so no worries

10% is just fine, for purposes of calibrating the battery meter. Preferable actually. You shouldn't actually drain the device until shutdown. There are safeguards that are supposed to ensure the battery voltage does not drop too low (its not actually zero when the phone shuts down). However, in reality these safeguards are not always failsafe and I've seen plenty of cases on various Android devices where letting the battery drain to shutoff renders the battery unable to take a charge (below the minimum threshold voltage). Sometimes, letting the battery charge overnight will bring the battery back. Otherwise, you are pretty screwed, as the only remedy would be a battery meter with a boost function.
In any case, the battery meter is not very accurate, even under the best of circumstances, so letting it drain to 10% is plenty accurate enough. Then let it charge to 100%, and let it sit at full for a while, as fully saturating the battery takes extra time.
---------- Post added at 11:15 AM ---------- Previous post was at 11:08 AM ----------
That said, its hard to say what "moderate use" means. Everyone uses their devices differently. If you are playing intensive games, downloading files, heavy internet usage, it can drain the battery much faster than other activities. And the number of hours of screen-on time is key. So the idea of getting some battery stats and screenshots, is a good one.
I haven't been tracking screen-on time myself. But I find the battery to be decent. I use it a good amount in the evening (don't bring it to work) mostly for reading and web browsing. I have brightness on 40-50% usually (sometimes less, if the room is darker). The battery was just under 40% after 2 nights of use (maybe 40 hours after the last charge). Just guessing, but maybe 3 or 4 hours of screen on time?
Some online reviews mentioned the battery life is not as good as some other comparable devices (such as Nexus 7 and iPad Mini). Not surprising, since the Note 8 has a faster processor and higher resolution screen than either. And so far, battery life is not amazing, but seems comparable or better (better drain while idle) than my old HTC Flyer tablet. So for me, thats just fine.

I got about 4 hours screen-on time on my first battery cycle with heavy usage. Was playing games, movies, internet browsing, etc. My second and third cycles were better, giving me 5-6 hours screen-on time with moderate to heavy usage. Didn't really play any movies, but did play a fair amount of games and stuff.
On those later cycles my screen-on drain represented about 85% of my overall drain. This leads me to say that you can expect 4.5-6.5 hours of screen-on time with the Note 8, depending on usage. Keep in mind that I keep wifi always on, disabled bluetooth/auto-sync/smart stay, stopped some running apps like Maps and Factory Test, and kept brightness down to about 15% of the max setting.
Screen is definitely the big drain here, and these results lead me to believe that even with root and apps like Greenify I would not get much better results. Looks like any further battery savings will need to come from a custom kernel and custom rom (unless maybe you root and then underclock/undervolt using a third party app like Voltage Control or SetCpu). Anyone else have similar (or different ) results?

While his terminology might have been a bit clumsy, he is not completely incorrect.
The terminology of "training the battery" invokes the concepts of conditioning the old technology NiCad batteries to prevent memory effects, which are not a concern with Li ion batteries, which is what you seem to be referring to. Folks on XDA will often talk about conditioning or calibrating the battery, which can be a bit misleading (as often they have the behavior of the old NiCad batteries in mind when saying this).
However, it is true that the battery meter needs to be calibrated to be completely accurate. This calibration has no chemical effect on the battery itself (like it does with NiCad batteries) but simply effects how the current readings are displayed by the % battery meter on the device's screen. Without fully charging and draining the device, it doesn't have fully accurate "flags" associated the current to battery %.
http://batteryuniversity.com/learn/article/battery_calibration
Failure to calibrate the meter won't have a negative chemical effect, like failure to periodically condition a NiCad battery. And therefore it won't have an affect on the battery life. But properly calibrating will give you the most accurate % battery reading possible. The battery meter is not accurate out of the box, after a ROM flash, and an OTA may also reset the calibration.
As I've already mentioned in a previous response, I don't recommend draining the battery to shutoff. As doing so can lead to the battery no longer taking a charge, and the device no longer powering on. Its rare, but it does happen. Fully changing, then draining to 10% or so is enough. Full cycles are also not good for the long term life of the battery, although just doing it once every few months is still acceptable.

The charger for the Note 8 is 2 Amps, while most MicroUSB chargers (at least for phones and other small devices) are 1 Amp. Although this varies, and there are other tablet chargers that are also 2 Amps; but these are far less common than phone charges that just about anyone with a phone that isn't Apple will have.
What this means is that the 1 Amp charger will charge the Note 8 very slowly. I tried mine on a 1 Amp charger just once so far. Left it on for maybe an hour, and the charge only increased by a few percent.
So yes, you can charge with most MicroUSB chargers in a pinch. But it will be slow.

Don't get the physical plug of a charger confuse you - I believe this tablet needs a 2amp output from the charger, meaning just because your charger has the same end connection, it won't necessarily help you charge this battery. I've had my users come to me thinking their devices are defective because they somehow started charging their tablet with their Bluetooth headset charger.
Someone also mentioned the black wallpaper that might help with the battery consumption - I believe that is only helpful on AMOLED screens that Samsung has used on other devices.
I'm really still on the fence on keeping it after I bought this - I'm coming from a GT 7.7 which had excellent build quality,screen, and battery life. The loss of the AMOLED screen for both graphics and battery efficiency is bothering me. I put both up side by side and feel disappointed that Samsung couldn't just make a JB updated 7.7 with new CPU, 2GB RAM, and stylus with the same design and beautiful Super AMOLED Plus screen. It's not even the price - but just feeling like I'm getting a somewhat inferior device (in a few but important aspects) from the 7.7, when it's supposed to be an upgrade to the older device.
I've seen the news about an upgrade to the 7.7 possibly coming, but will it come with the stylus that is also important to me and the other software enhancements from the Note 8?

Funny thing happened on mine.
The battery was VERY BAD the second day, but it could play live streaming for two hours when the battery was 1%. As soon as the tablet went off due to depleted battery, I charged it until it went all the way until the "full battery" came up.
After that, the battery is much better now, so don't say anything "dumb" or any nonsense because it works.

That is correct, having a black background does not effect battery life on LCD screens.
On AMOLED screens, black pixels are actually not emitting light (while pixels displaying other colors emit light), which is why a black background will cause less battery drain than other colors.
On an LCD, the liquid crystal layer that depicts the colors is not itself a source of light. Its lit from the back, and the light intensity of the backlight is the same regardless of what color is being displayed. How much light is blocked or let though by the liquid crystal layer varies depending on their alignment (what color is being displayed). But this doesn't affect how bright the backlight is, anymore than pulling a window blind makes the sun burn less hydrogen.

How is the batter life for you guys? . I seem to be losing 60% in 6 hours with 30 mins Google navigation and some texting and browsing.

This is what I've been getting for battery life on my Verizon Samsung Galaxy Note 7. I've cut the bloat apps I don't want, almost all of my data connection was on wifi, web browsing, sending and checking emails, no gaming, had to turn it off twice (applying and reapplying a screen protector), used Bluetooth once for about an hour listening to music in the car, made a few calls and received a few calls. I turned battery saver on right around 85% battery life from 100%. The battery saver was custom and I left the screen resolution at 2k just only enabled limit performance and max brightness to 90%. Just over 9 hrs screen on time works for me.

Yeah mine hasn't been great. Think I'm gonna run it until Wednesday and if it's still not good I'm returning it and going back to my s7e in the meantime.

Mine has been doing very well, better than my note 4 did by a good percentage. The other day I tried to use Google maps for navigation but I was apparently in a dead area. Later that night I was checking battery stats and I saw that maps used 11% for a matter of minutes while the next non-system app was like 3%. There might be something wrong with the app on note 7 then maybe.

Mine has been really good. Usually when I leave work I'm at around 40% (on my S6 edge). Today I'm at 79% (on the Note 7).

So far, my best has been down to 14% in almost 16 hours, with about 5 hours of SoT.

Seriously, if you are getting 9 hours of screen on time, you have to have disabled so much of the functionality of the phone that I don't know why you would buy a Note. With every reviewer and average person getting 4.5-5.5 hours SOT, it just seems ridiculous..

I think it's satisfactory.
I find myself actually using it a lot more than the S7E AND the battery is better to boot.
Personally, if I couldn't use the Note 7 any more, I'd go back to using my iphone 6S+ before I'd use the S7E...
Or the Note 5 / 6S+.
From ergonomics, the S7E is just awful. It reminds me of using a Windows 8 PC for the first time! Mainly because of the horrible, horrible touch sensitivity of the screen and edge.
Perhaps the battery life is better because I've never charged wirelessly? I've heard that if you charge with the cord your battery life, particularly idle, is far better. I don't mind plugging in. USB-C connector is long overdue. No more fumbling in the dark trying to plug it in, scratching the bottom around the connector in the process!

The built in battery monitor is bad. I ran antutu benchmark once and it tonight it took up the equivalent of my whole battery. 5 minutes of app time and only 3% in real life. I have done a couple of full battery cycles to just make sure the software learns the top and bottom ends of my battery. Slowly figuring out what is killing battery and what not. If I have extra drain it's because something is glitching. I have been unplugged since 1 am last night. Still at 10% with almost 5 hours of screen on time.

I've cut the bloat apps I don't want, almost all of my data connection was on wifi, web browsing, sending and checking emails, no gaming, had to turn it off twice (applying and reapplying a screen protector), used Bluetooth once for about an hour listening to music in the car, made a few calls and received a few calls. I turned battery saver on right around 85% battery life from 100%. The battery saver was custom and I left the screen resolution at 2k just only enabled limit performance and max brightness to 90%. Just over 9 hrs screen on time works for me.

What is that dark theme?

Seriously, if you are getting 9 hours of screen on time, you have to have disabled so much of the functionality of the phone that I don't know why you would buy a Note. With every reviewer and average person getting 4.5-5.5 hours SOT, it just seems ridiculous..

I don't feel I disabled much of the phone, all I did was disable approximately 12 apps that I don't and or won't use, and at around 85% battery left, I turned on a custom mid power saving feature and used the phone a good amount over a 34+ hour span. This whole setup took me less than 15 minutes, so I'm not sure why you seem to have an issue with my choice in phone. It's not like I went in, rooted the thing and froze an incredible amount of apps, slapped in a custom kernel and messed with voltage and loaded some slim lightweight custom ROM. I simply used power saver and disabled some apps. This took no effort at all, simply sharing what I'd been getting, as others didn't seem to get as much out of their battery.
I got a note because I can pull serious hours SOT, multi task like a boss and enjoy multimedia on this gorgeous screen. I've had Notes since the Note 2.

It's sd-black from the theme store.

I agree with the disappointing battery life. I had a galaxy 7 active and after a full day of work doing the same thing I had about 75% after my day ended ,with my note 7 I had about mid 60%. Keep in mind I dont use my phone except a little before work and on my breaks.i also turn my Data off when I'm not using my phone and yes all my bloatware is shut off. If we had root I'm sure I would be happy since I get a lot more out of my battery because of my root setup .

Im getting great battery life and i can usually find a place to plug in for a short time which refuels me quickly. I had to manually set a few apps to be quiet which is fine otherwise im happy so far.

Thanks. These white settings pages are blinding me.

Could you please share what apps you disabled and what power settings you are using so I can give it a try? Thank you.

I use Nova Launcher Pro for my icons (out of the playstore) mixed with the themes from the theme store, I'm enjoying it!

Yeah, sure. I've got a couple things to do first but I'll list the apps I disabled and show you the power saving setup I am using in just a bit.

Tnx!

Battery-gate has everyone paranoid.

This sounds like BS. When Samsung investigated 90+ cases of exploding batteries, it found that 26 reported cases were fraudulent scams - this was in the news today.
It sounds like the same ****.

This.
I would believe the below from the article before I'd believe Samsung's stupid enough to make the same or similar mistake twice. I was worried about QC on the replacements considering how fast they're racing down the production line. Mine's perfect BTW. Any articles about Samsung because of what's happened is guaranteed click-bait. A Note 2 overheating on a plane made front page news with whatever (still to be determined) happened to it being tied back to the Note7 issue.
"The issues being reported in South Korea are related to minor errors with the mass production of the new units."​

I m not seeing anything near this. in fact my SD820 device runs better than the original did

Mine seems too also but I thought it was all in my head. It seems smoother and snappier for want of better words. My old phone would occasionally get choppy and stutter as if it was struggling with something in the background. The new one doesn't. It's on AT&T and the new phone's shipping s/w was the same as the old phone's updated s/w. Curious.

My s7 edge and note 7 (both exploding and non-exploding versions) have always had times where they charge slower than they discharge. (Waze + Pandora when it is super sunny, so 100% brightness. Even on QC2.0.)
The new note7 (and/or new firmware) pops up a warning to say as much. The S7E had an overheat warning that came up occasionally in similar conditions (even air-conditioned, DC summer is warm..)
I think the only difference is the notification that its happening, which is nicer than discovering after a drive that you have been losing power the whole time.

I'm experiencing the very slow charging issue. In fact when I was watching a movie while fast charging it was losing charge!?

I have experimented the same thing, actually ending with less batt while using and charging with other devices, so, this happening with the note 7 indicates nothing wrong with the batt

Customers in South Korea who received a replacement device have reportedly complained the phone's battery is overheating and drains too quickly after use, according to a report by YTN, a TV network in the country.

Fast charging does not seem to want to work on my new one, with stock charger brick and cable. I am hoping I don't have to go BACK to TMo and get another new phone.

my replacement seems identical to my original, same charge speed, same discharge speed.
as for the people saying about watching movies and such and the battery ending up lower, that is normal, if you are running the screen and charging not only does the battery get warm, so does the CPU so the phone will start to throttle the charging. I've had phones in the past that refused to charge once the CPU got above a certain temperature. this is just people being paranoid or looking for a way to get money as mentioned above with the fake tales of exploding batteries.

Odd. I use my Note7 (pre and post replacement) with Android Auto via USB. Android Auto really puts a load on the phone. Even off the wimpy output from my car's USB port the phone never loses charge and frequently gains it. My previous Note5 was the opposite. It would stay even most of the time but would lose charge on occasion. The only difference between the two scenarios is I got a Orange-E 12" Type C USB cable to use with my Note7. So my experience is different than yours.

I suspect the screen is the big drain. 100% brightness is vicious. Isn't the screen off for android auto?
Things it's usually doing when it drains (starting from 70% or so) :
Overheating (direct sun, no ac pointed at dash or top/doors off)
BT music streaming + wear
GPS
100% brightness
QC2 (aukey car charger)
Even without overheating that combo usually only gains me about 5% over 30 minutes.
Unrelated, but without getting too far off topic is AA worth the jump? (~900USD if I want my steering wheel controls and stuff)

Yep. When in use and the display is on its black with the Android Auto logo. But the phone's still using all its radios and if navigating pushing data to an 8" display so the phone's definitely under load. I have a Samsung Fast Charge car adapter but the problem with Android Auto is it doesn't let you connect by BT so the car's USB power output is all you get. But as a comparison under the exact same conditions the Note7 definitely either drains less or gets more power than my previous Note5 and both phones are/were configured identically.

A black screen with amoled means the only pixels lighting up are the ones in use. The screen itself is a massive drain so the more pixels are lit up, the more the juice is drained from the battery. That's why AOD doesn't kill the battery fast.

Ive used a USB multimeter on both my old and new note7.
No matter what, old or new note7, the charging rate gets cut exactly in half when charging with the screen on. This happens when using a quickcharger or a normal 2.4a 5v charger.
So if you want full speed charging the screen needs to be OFF.

On my replacement Note 7 I noticed that if you are doing allot with the phone, it still gets hot, the battery does take a little longer to charge with both the Samsung charger that came with the phone and an Anker IQ 2.0 / 3.0 charger. The phone does seem a little snappier/faster though.
I just want a removable battery to end all this bull * and I will pick the battery I want to power my phone.

The biggest advantage for the integrated battery is that the unit is completely sealed from water.

I beg to differ, because they have that wireless backpac battery that is completely sealed from water for the Note 7. The purpose of the permanently installed battery is for the NSA to track people since the battery cannot be removed from the phone.
