Display Issues

Ill make this plain and simple, im having really high display percentage on my N1 and i cant figure it out. As u can see the picture below, the display % is at a 81%!!! and here is the thing, i have only 4 widgets running. At the time that i took the pic i had the brightness at 30% but even if i have it at 0% display % will always be around 60-75%.
This is what i have on my N1:
Rom: cyanogen 506
Kernel: persiansown uv-oc
So this being said, this display problem is affecting my battery. i get an average of 12-16 hrs which its pretty good, i think but i used to get 32-36 hrs. Can anyone know what could be the problem? Cuz im totally stumped

do you keep your screen on for long periods of time?

oh no, i turn it off when i dont use it. i have the screen timed out at 2min, 1 min, 30sec, ect.. and still get same results.

correct me if im wrong, but i think the battery status (usage) is staggered. Meaning itll post every thing that uses the battery and will display in percentages and will total to =/- 100%.
So if the rest of the phone is only using 19% then your screen would then display around 80%. Lets say the rest of the phone is using 50%, then your battery would then display around 50% of battery use. But its still using the same power consumption with the two instances.
again, correct me if im wrong, i briefly remember reading that somewhere. Cause i guess someone had been using the phone with 50% brightness and when he decided to put it at about 10% he actually increased 2% on his display usuage. hahaahha!

On Desire ROMs it's only 17%.. or sometimes lower. I don't really care though.. Lol.

It is all relative, always adding up to 100%. If you're phone/wifi/3g/cell percentage is really low, then the display will be really high. The higher the display is shows how good the rest of the system is at conserving power. The display is the largest battery drain on the system. If something else was higher, or even close to the display use after you've used the display for a while I'd be scared something was wrong.
Let's say you charge your phone, never turn on the display, and leave it sitting for 5 hours. Then check percentage. Cell idle, Android OS, and things like that will be the largest, totalling 100% battery use. But your battery may only be down 10%. Then use it for an hour with the display on, display will suddenly jump up to 80% and everything else down to 20%.
Or in other words. Let's say you have used 20% of the battery (battery level is down to 80%) On the battery usage screen display takes up 90% of that, and the rest of the system 10%. That means out of the 20% you used of the battery, 18% was used by the display, and 2% by everything else.
People think Cyanogenmod is bad because the display is so high compared to other mods, but it means that the rest of the system in cyanogenmod is actually more power efficient than the others. So display will naturally be higher relative to everything else.

I believe this is a known issue with 2.1

so i guess in a way its saving power,right? since it is not didtributing power all over the place.

i think its because of the Screen AMOLED is probably a battery eater, i think its fixed and its called Super AMOLED

battery life gettingg worse

When I got my phone I use to get 6 hours screen time after a while went down to about 5 and a half aftre about 3 weeks of that 4 and a half now I'm averaging 4 hours screen time I don't know why this is happening I keep smart futures off air futures off other than quick glance and BT off NFC off etc ? Same settings as always brightness 50% unless I'm watching video where I set it full

Yup..Its not like the old Ni-cad batteries in which you need to completely discharge it before charging.It is not a good practice to do the same with Li-ion batteries.It may actually lead to worse battery life.It's recommended to charge the phone at 40% and charge it till 80%.

Im pretty sure you have a lot more apps than you did on day 1 of getting your phone that will use additional power sync
Also as stated do not let the battery completely drain as this may limit the capacity

Q. battery question

Is anyone experiencing weird issues with battery before recharging? i had 2 days phone on batt and 3hrs screen on. It was at 53 % before i decided to charge. I fully charged it and now im losing 10% every hour even with phone on idle. Its weird cause every other charge will last a long time.

Yeah, I'm still stock on this phone and I'm getting inconsistent battery life. I usually charge every night, so I'm running about 16-17 hours per day. Almost identical usage each day but one day I'll plug in with 45-50% remaining and the next it will be dead when i plug in. Very odd. I'm going to root this thing just so I can get rid of the bloat apps. Well, that may not be the only reason I root. I may be compelled to put some AOSP on this and see how it rocks it.

well i don`t really recommend to ROOT stock rom, it caused for me a battery drain ! also KitKat known for drain issue even on Pure android on Nexus 5. I don`t really know a fix but i`d give u some tip and it might help
1. Re-flash D80020c
2. After re-flash do a factory reset
3. Don`t root or mod your OS
4. Turn off Sync or Location Service (or set to battery saver mode)
i did those steps and i have 34 hour on battery:
3 Hour screen on time (and about 30-40 min gaming in this 3 hour)
Left about 49%
i hope i helped a little

Potential solutions:
Have a look in Settings > General > Battery and see what seems to be using the most power. You could have a problem app that’s using GPS or trying to update frequently. If you can identify the culprit then you can remove it.
There’s a slim chance you have a faulty handset. If adjusting your usage and tweaking settings doesn’t’ result in any improvement then take your LG G2 back to the retailer or carrier and get a replacement.

I always have location turned off with all bloatware rwmoved. I honestly think you have to drain it to about 20% then charge. Cause i never have problems when i do that. Gonna try and drain it out again and recharge and see what happens then.

Its kitkat,it says rooted d80020c in my signature. Well here is my latest results. Left it on overnight and was at 53% with data off. Checked it this morning and everything was back to normal again no battery drain or low estimated battery times.weird cause i charged it around this percentage. I think you have to take it down to at least 20 before charging will find out later today when i charge.

well i really not heard about Deep sleep drain but while idle it`s drains bit faster then JB, with jb i could get max 40 hour and about 6hr screen on time and + 10-15% battery while on KK i can get 42 hour but about 5 hr and 45 min screen on time with 0% battery it`s seems a bit problem for 4.4.2 i think Google will fix it and hopefull we`ll get new update from AT&T if this prob will fixed
P.S i saw that if battery at 100%, overnight it won`t fall to 99 but while battery is on below 100% it drains about 1-2 % overnight is that a known prob?

2% overnight is pretty good, given that it's on WIFI I'm assuming?
I lost 25% overnight last night when I was off WIFI, so I factory resetted mine.

Took it down to 20% and discharged and its fine. Im guessing its a bug,but, easy fix just take the battery down to 20% or lower before charging

[Q] Battery remains on 1% for almost one full day

I am creating this thread after exploring the options documented in other similar threads, where I have posted the same issue.
My original battery was weak and I got a new one for my Defy green lens.
I saw that the phone stays at 1% for a long time and then tried several of the tools which remove the battery stats and claim to re-calibrate the battery.
After several such cycles of full 100% charge and discharge till power-off, the phone's standby time has exceeded 2.5 days - out of which it remains at 1% for almost one full day.
Note: I am running Quarx's 4.4.4 nightly.
What are the other things I can try? The phone is used only as standby so I don't mind wiping it off completely and putting stock ROM and observe again.

Dont worry . this happens to me also.. im too bought a battery of 600rs from ebay and battery stays 1 % for a day...
For an investigation i checked the battery voltage (at 100% charge voltage will be 4.2) when it drops to 1%, its nearly 3.9 and phone will keep working till voltage reduces to 3.5... im getting 2 days minimum backup of moderate use...
now to explain why 1% , this is an answer i gt from FB group .. "dnt expect Original battery at 600rs wen its actually cost 1200rs, they are actually replica of real and the so battery circuit send false info to phone, and phone calculates percentage remaining on this "
i tried to switch some cm7 version but in all battery drop at 1% happens.... so i ignored it and my defy still rocks in daily usage after 3 years ...

I find it odd that this is not an original battery.
The battery charge is pretty good - more than 50 hours - no usage of the phone - but poor 2G connection/ weak signal.
I can contact the ebay vendor if that is the case, but I need to be sure first.
I have now put my original battery and I will see if it drains off in the same way or not.

I paid Rs. 600.
I put my original battery (3 year old) and that does not show the 1% issue, though the battery life is less than 2 days on it in standby mode.

Lollipop battery issues

Hey guys i got a s4 for free a few weeks ago and the battery was having issues so i brought a new battery from Samsung for $50. I guess the phone is $50 now huh, still that's a good price. Anyway i have an improvement in standby time over the old battery that seemed to drain no matter what, but i only get around 2hrs to 3hrs screen on time full brightness with a mix of auto. The phone tends to get warm when its below 40% power. Also using the phone drains it at a fast rate, but standby only 1% per 8mins or so witch is good. Im backing up with twrp and titanium backup, ive tried recalibration, and im about to do a factory reset on this (stock touchwiz)
Sent from my LG-D320n using Tapatalk

Battery calibration apps are a placebo.
Anyway, let me tell you a little story:
2 weeks ago I watched a 2 hour movie on my phone. Started from 100% ans towards the end of the movie I was left with about 50% battery.
Screen brightness was around 60%, WiFi was enabled and the mobile reception was 4G.
All things considered I would assume I can get 4 hours SOT, since it took 2 hours to get from 100 to 50.
This is on a custom rom and battery oriented kernel settings.
Also take into account that I was watching a movie, so the CPU was idling most of the time. Doing tasks and switching from one app to another drives the CPU up.
Your screen-on time seems acceptable to me. I have to mention that my battery is one and a half years old, but I always took good care of it (I never let it discharge too much and never left it charge too much, as both of those, over time, can reduce its storage capacity).

Im using Albe95 rom with a custom kernal and the battery is draining slightly less, ive reduced my brightness to 60% and its drained from 100% to 77% in standby and extremely light use in 6hrs (about 4hrs standby drained 6% and 2 hrs of on off use every now and then drained about 17%. I guess im used to my old LG L70 D320n witch could hold up at full brightness forever. Will Cyanogenmod 13 bring much improvement for me?

I don't know. Maybe Optimized CM13 because it has a custom kernel and you can select battery or performance profiles.

You won't miraculously get 5-6 hours SOT even if the battery is new.
Maybe with lowest brightness, WiFi and mobile data off you will.
Underclocking and undevolting might help a little, but I don't see anyway of getting more than 5 hours.

There's a guide in the general section, _Bon_Bon's tweaks.., Something along those lines is the title.
It has a guide on how to increase battery life.
The guide is based on alucard kernel, though.
Alucard kernel is available for any 5.0 and 5.1 roms. But there is no public build for android 6.
Only JDCTeam roms have alucard kernel for android 6. Those roms are Optimized CM13 and AOSP 6.0 rom.

Ok so slowly things have improved but today when it was at 9% (6:30pm charged this morning) it froze up and i pulled the battery. Then it jumped down to 2% at restart! This has happened before (cant remember if it was on stock rom or the note 5 rom im using on it now) from 40% freeze, pull battery, restart, 22%! Any idea why this happens. I talked to samsung about the battery performance and they just wanted me to send the phone too as "its not just the battery" just for more money instead of honering their 3 month ****ty warranty! Stick it samsung my next phone will be lg like the rest, even though i only just brought this damn phone

The freezes might be caused by CPU undervolting, if you did any.
But the battery percentage dropping suddenly is a sign of a bad battery. It might drop 2 or 3% during the boot up, but not 20%.

Samsung say the phone is the problem. Today i got to 40% and it jumped to 30% within 20 mins. Then i pulled the battery and started the phone up, repeating this multiple times to see the battery percentage. It jumped between 24% 15% and 19% up and down each time i pulled battery and restarted (no crashing just to see what happens). Is this enough to tell Samsung ITS NOT MY PHONE.

Apparently they refuse to accept the possibility that they might have sold you a faulty battery, so they blame the phone.
I don't see how the phone might drain the battery from a hardware perspective.
It's possible from a software perspective, but since you changed roms it is unlikely to be software related.
Did you install any apps to check if the phone enters deep sleep? Or if there is anything keeping the CPU at max frequency?

How did you calibrate it?
Battery calibration apps are a placebo. What they do is they delete the batterystats.bin file which, as stated by a Google engineer, has no relation to battery life or the battery display.
Also, that file gets deleted automatically at every reboot by android itself.
What you could do is:
First let your battery fully discharge, until the phone turns off. Then try to turn it back on. If it turns on, proceed to use it until it turns off again. Do this until the phone won't turn on again.
Now the battery is completely empty and you can plug it in to charge. Let it charge to 100% without interruptions.
Take into account that it can take up to 3 hours to fully charge.

Haha done this before to no avail. Will do again but i noticed battery life is generally better if i leave it charging for 10hours after its charged fully. Instead of taking it off when it gets to 100% but i think a long worded and very angry email is about to be sent to the Samsung repair centre
Sent from my LG-D320n using Tapatalk

on my travels around google I've read many times that with lithium batteries you NEVER want to completely discharge or overcharge them. give it 10 minutes extra once fully charged, not more. you're damaging the poles or terminals or something I can't remember fully when at either extreme. all you achieve is a shorter lifespan for your battery.
discharge it until it turns off but never until it can't turn on again. it has a chip in the battery that needs to stay powered too.
