Screen on time with full brightness? - Nexus 4 Q&A, Help & Troubleshooting

Hi there. After reading many threads on battery life and screen on time (which youre all probably sick of hearing about now), i have a question about peoples results. They always describe what they did with their phone, and what toggles were on etc, but they never mention the brightness.
I see people getting 6hrs+ of screen on time, is this with the brightness at 50%? 25%? 10%???
What is a normal SOT using FULL brightness. Thanks

I always have my phones on full brightness, There are always comments on here about turning stuff off like sync, google now etc and saying "whats the point of having a smartphone"
I put the screen in the same bracket.. I've seen people boasting about getting 6 hours screen on but when questioned they have their brightness on 10% or whatever. Whats the point?
The screen on both this and the gnex are lovely, and only can you appreciate it by getting out of that mard ar5e zone and cranking the brightness up.
3 hours screen on is enough for my use, i'm getting that now using franco's kernel (was only getting 2 when i bought it)

My screen is auto brightness and it's usually 50 percent brightness and hundred here and there and I get 5 + hours on the matrix kernel.
It's usually the stock kernel that has a low battery life

Underclocked and undervolted (no difference in performance) I can push 4 hours SOT 100% brightness, with heavy gaming, web browsing and calls.

Whoever gets 6+ is using auto brightness.

But it's not like the auto brightness is trying to intentionally save battery by lowering brightness to an uncomfortable level...

Display battery use 67% Normal??

Hi Guys,
I am on Roto JMI v2 and noticed that the battery consumption on Display is around 60-70% all the time even at minimum brightness and power saving mode. Is that normal? Help?
Cheers!
I am on stock and it's always on 83%, so you are better off. My guess is this reading shows the total battery consumption and not the current battery usage.
Normal. Same for me.
Hey thanks for the reply guys was really confused since read on xda a post where the guy mentions 20% usage on overcome rom

its not a bug, the display is what always eats the battery in devices.
Another thing that puzzles me is that whether I have the brightness at MINIMUM or I have it around 35%, the phone still showed the same %age of battery consumption. So does this mean irrespective of the level of brightness, it is going to consume that much of juice or increases with level of brightness (which is only logical) ?
Also, it seems my battery usage gauge is all messed up! Even after around 5 hrs on standby and intermittent usage, it showed 12 m 5 s. Very strange!
When you set the LCD brightness to minimum, current still run through it to operate, if not it will be totally blank (as in darkness). So, 35% is good enough.
My personal opinion, the battery status is always a bull, I'd never trust it, after experiencing so much battery issue prior to my upgrade. I would just enjoy the fun of owning the tab and when it's time to upgrade (to another tab), nothing else matter..............
So long as it kills my time (by playing games, listening to music, watching youtube), improve my efficiencies (by having the necessary apps), keeping in touch (emails, facebook, Skype, phone calls, etc) and most importantly, it is extremely portable. Other than that, I just charge it before I go to bed.
It serves my daily needs. I am happy.

[Q] Battery Life - Screen On

I've had my Droid X for about a month now. In general it goes about a day before I have to charge it. That seems to be about normal. My questions is in that day of total time, how much time can the screen be on before having to charge. I seem to get about 2 1/4 to 2 1/2 hours with the screen on. That doesn't seem that great, but I was wondering what other folks are seeing.
Thanks.
Depends what else is going on for the phone, and what the brightness is set to (in extremes, what the temperature is).
But, even in the worst case, 2.5hrs is a bit low. I recently got just about 3 hours streaming Netflix, 100% brightness, on a decent cell connection, on my 11-month old DX.
I would expect close to 8 hours on a constantly on screen, just running the clock, 1% brightness, in airplane mode.
Extended Battery
I didn't mention that it was about 2.5 hours, with the extended battery (1850maH). I'm running GB, auto brightness adjustment, no over/under clocking. Push email/calendar/contacts/tasks from our Exchange server. Auto-off after 30 seconds.
Shouldn't I be able to expect at least 4 hours screen on time under this configuration?
Yes you probably should be getting better battery life

[Q] How to improve screen time?

Hi,
And just a heads up, I am very new to flashing and kernel modifications. I do have a basic understanding as I've read through previous posts. The screen time posts however just post people showing of their screentime/battery life but not explaining clearly how they got theirs :/ and what conditions they were under.
Currently Im using a nexus 4 on Paranoid Android 3.56 (android version 4.22) and Franco Kernel milestone 2. I've underclocked my cpu to 1024mHz and under volted everything by 75mv.
I use juice defender ultimate and greenify. I keep sync on 24/7 and autobrightness.
My standby battery time is phenomenal, Im already on 9+ hours and still at 83%. But I am not able to break 3 hours of screen time.
I've been seeing posts with people claiming over 4.5 hours and even hitting 5 hours. How are they doing this?
I'd like to get 4.5 - 5 hours of screen time also but am not sure how to achieve this. So please help me with the configurations necessary to improve screen time for my phone. My stand by is already phenomenal and have no complaints at all about it.
Turn off auto-sync and lose juice defender. That's it.

Lower screen brightness is the first thing you should do if you want better screen on time.

did anyone "calibrated" their nexus?

I'm moderately using the nexus and only getting 5ish hours of screen time with brightness halfway. And people been saying that they get 7+ hours.
If you happen to be one of those people, did you calibrated yours? And how do you do it? I heard you have to drain the battery and then charge it back up. Does it work? Or is it just a myth?
They are many variables involved here beyond screen brightness. You are not going to hard core game for 7 hours out do anything that has CPU/GPU running high.
I keep my brightness set to auto.. Half way seems way to bright to get any decent battery life.

I get about the same battery life on 50% brightness
Sent from my SAMSUNG-SGH-T989 using Tapatalk 2
About 6 hours of use. If I let it sit I get a day of standby.
Games, Internet, and netflix kill the life for me.
Last week I took it to work and forgot my plug. I watched Netflix on the battery for about 4 and a half hours. It was at 8% when I left.
Avg of 6 seems the norm. /shrug
That seems about right actually at 50% brightness. I keep mine on auto but it is usually at about 10-15% brightness and I can get 6 hours all day long over a bay or two of the charger

From initial setup (battery came at 62%) I let it completely die and then proceeded to do an initial battery charge cycle (charged it for 6 hours). After which I put it on the charger at about 14% which is normally right as I go to bed for regular charge cycles.
As for my battery life, I get an average 8 hours screen time while doing heavy gaming, watching Netflix/Youtube, listening to music, reading, and lastly browsing the web. As for standby time 3 days on battery on average (with Wi-Fi off during Sleep and always scan for Wi-Fi off).
This is with auto-brightness as I've found zero need to adjust it save for a few occasions I had to raise it for a few minutes while outdoors. If you want great battery life, leave the Nexus to it's own devices It knows how to handle it's brightness; very well I might add.
Granted your mileage my vary drastically as my Nexus 7 was flawless when purchased with zero of the known issues. (It also brought me to this lovely forum. )
Realistically you only need like 10-25 percent brightness on this thing at most times. This thing goes really bright.

auto brightness
About 10Hours of battery life.
Get about ten hours of battery life. I have brightness set to half. The real part that was saving me battery is the advanced wifi settings. I set it so that it never searches or keeps wifi on when sleeping. Also manually turn off wifi when I don't have coverage. I use alot of YouTube, internet and Netflix.

My battery stats
Hey there!
I bought this phone on Monday and I started using it yesterday. Here is a screenshot of my actual battery.
I've used 3G and Wi-Fi, downloaded some apps and used GPS a bit. Now I'm using only 2G connections and the brightness is set to low.
Very happy with it!
Just a request
When you all post battery Screenshots please mention the on screen time all of you get and if possible mention the brightness also
Addition
Mention screen on time...
Mention rom (when available lol)
If possible mention ur personal setup like u greenify apps or not...
First charge.
5h screen on, autobrightness, 1 1/2h gps and some other game testing so pretty much like the old G
Seems very solid, 5h SOT. I might be joining your community soon
On average usage it will last for one day
The battery life is better than what I expected. It has dual sim and a large screen but still manages around a day on battery.
Managed to get slightly over 7 hours before the phone shut off.
GPS: Power saving mode
Screen: Brightness set to indoor conditions (manual / below 10%)
ROM: Default
Battery Saver: Disabled
Battery saving apps: None installed
WiFi and Sync: Always enabled
Screen Time Out: 2 minutes after inactivity
Usage: Mainly Facebook, Chrome, WhatsApp, few YouTube vids and Google Docs. Nothing intensive.
Phone charged from 0-100% in under 2 hours without entering the OS. I used Anker Power IQ 40W 5-port desktop charger and Moto's USB cable. Back of the phone remained cool throughout. Could have squeezed more life out of the battery by setting screen time-out to 30 seconds, but I'm happy with 7 hours. Used to get between 3.30 to 4 hours on my NEXUS 4.
Moto G has one of the most (if not the most) efficient SoC (especially the CPU core). So the biggest improvement to battery life comes from adjusting the screen manually. Don't use auto brightness if possible and keep the brightness low without sacrificing image quality. Mine is set to below 10%.
If you have any questions, feel free to ask :good:
Impressive

WOW, that's really impressive. Yes, auto brightness can drain the battery soon. I use auto brightness whenever I'm outdoors for a couple of hours and I get 5+ hrs of usage. Very happy with the battery life.

Over someone?
I'm in doubt between G and the new Moto Moto X (2014)
Who has better screen time on 3G / 4G will take my money.
No gaming in this cycle of battery charge
But internet use is there over Wi-Fi.

Very happy with battery life. Very first charge, just received phone in the afternoon and was fully charged by 3:30 or 4. Downloading applications, syncing accounts, installed GTA:SA and played a tiny bit(used a controller through OTG) snapped pics, took some slo no videos and auto brightness. Texting, IM'ing, some YouTube videos, etc and also music, which sounds amazing through the speakers!
Not bad at all
Battery is not bad. I was using Wi-Fi n downloaded applications. Still I got it for 20 hrs n had around 15% left.

Yeah I was kinda amazed. Wasn't expecting 7 hours. Expect the battery to increase even further when Android L is released
Five hours screen time
Pretty good for Android phone
My new Moto G has been amazingly good with respective to Battery backup. :good: When phone is idle... it is alove for almost 1 and a half day... Amazing.. I also had Lumia 520.. It could last for 2 days and still have juice left.. Very impressed..
I find the battery life to be average, I get about 3.5 to 4 hours of screen on time. Which is what most phones get, but the original G could go for 5hours. And by about 7pm, my battery run out.
You could get 5hours screen on time if you stay indoor and connected to WiFi all the time and on 50% screen brightness, but this is not for someone who is moving about, being outdoor and not connected to WiFi during work.
Battery is pathetic...The phone was in deep sleep for 8 hours. Battery consumed while in deep sleep, was 1% per hour
What's wrong? Feels like eclair days...
