What is your display power drain?

Maybe my battery is not trained yet, but so far, on my 2-days old n1, battey lasts for 4 hours (mid. backlight, no wifi, very little use).
Still running stock rom and not planning on rooting.
What I noticed is that in my battery drain stats show Display contributing to 80% of total drain. That's with display being on mid setting... is that normal? What is yours (esepecially for people with stock roms)?

Are you playing with the phone a lot? Like is your display always on? 4hrs still seems extream to me, I am rooted and runninng a custom rom, but even when I wasnt I never managed to get through the battery that quickly, and I use the phone a lot

Here's what I do to get good battery... I only keep backlight on like the a ****as hair..lol barely unless outside...... widgets are cool n all, but if there constantly updating thats polling your battery, live wallpapers are cool, but a battery drainer, I also keep gps, locations and bluetooth off unless using them, wifi also.. also the background applications setting uses battery but if ya want updating widgets no way around that...
Also look in seetings about phone, battery use and see what's eating your battery, I use my phone hours at a time so my display is most my battery drain which is normal, everything else is like 7 percent or less, mostly 2 or 3 percent. ....
I think thats all I do, but you may keep stuff on like widgets and that unfortunately eats battery..

I am running everything in my Sig. I have had my N1 for about 2 months now right around that. After a 14 to 16hr day with some heavy to mild usage I am still over 50%, but then again I have 3g turned off and i am only on Edge all the time since i am always around WiFi. So i would tell you 4 hours is a bit extreme but hang in there it does get better. I remember being around 25% for the 1st few weeks until it got better. Other wise do what Temperbad said that is the best way to go. Only widget i am running that updates every hour is my Weather one. Turn the screen all the way down unless it other wise needs to be up. I am sure that is what is killing your battery. Mine is always on the lowest setting until i am outside.

Sadly I'm rooted, but I will state my percentage too.
Weirdly, my display usage is only 15% on Paul's Desire ROM. Honestly I dont see how this may be - but that is what it says. My brightness is quite high too..

Yeah, I'm well aware about widgets and battery drain regarding 3G and all that, I've had PDAs for quite a while.
For comparison, my old and ****ty TP2 would drain about 30-40% of its battery with same usage that would drain my N1 dry.
I do remember that LiIons get better in a week or so of usage, but I wanted to hear what you guys are getting. Would love to hear from someone who's just bought an N1 like me.
It's under full warranty, so I'm not worried too much. Just an inconvenience.

I have my display set to "Auto Brightness," have a display timeout of 1 minute, have my email get synced every hour, and also use a live wallpaper.
My display accounts for 63% of battery usage.

Auto brightness will use more battery than keeping it low. Cause its constantly checking light density through the sensor to give it the correct lighting...

I agree, but disabling that, disabling GPS, WiFi, turning off 3G, killing all widgets.. ok yeah my phone will last me 2 hours longer, but it's also boring as hell.
Might as well go pick up a simple nokia for $10 - battery will last for weeks, but what's the point..
Not saying your advise is bad, it's a good idea.. just that all these advices to turn everything off - what's the point of even having a PDA then..

I've read otherwise, though I don't think that Auto Brightness is the optimal battery saving setting.
Obviously it's a middle ground between max and low.

Here's a report of my usage today:
~Wifi and 3G both turned on the whole time
~30 mins of MP3s with head phones
~20 mins of 3G tethering over Bluetooth
~40 mins of apps usage (mostly the Browser and the Gallery)
~8 mins of talk time
one 1 min update through the bootloader
have gmail sync turned on, also twidroid syncs every 15 mins
The Battery use app shows:
54% Display (active 6% of the time)
16% Cell standby
14% Phone idle
4% Wifi (active 51.6% of the time)
4% Android System
Right now 14h26' since unplugged, still having 43% of the battery left. The battery meter says 12 more hours until 0%.
All things considered, the battery life is quite good on my N1.
Edit: forgot to mention, the display is set to the middle setting with the Power widget, no auto brightness

Wow... that's some serious battery life.
Ok, some questions..
1. screen brightness setting?
2. how long have u had that phone (battery) for? Did it improve over time?
3. Is it rooted/flashed or stock rom?
4. you got any syncing widgets running (RSS/twidroid)? Live wallpaper?
Thanks a bunch for your input!

45% - Display

Just one comment. I keep Wi-fi and GPS on all day because Wi-fi sleeps when the screen is off and only polls when the screen is on if you're not using it. GPS is only used when your location is required in an application. i dont know why people are always like "you have to turn these off to get good battery life" (Notice wi-fi is 2%)
also i've been running 8 hours with moderate to heavy use (internet, music, phone calls etc) and I'm @ 40%. The drain from 70% - 40% seems to go so slow compared to 100% - 70%.

Sweet, thanks for the info. It seems my battery is also slowly "training" its way closer to these numbers.

Your right... about the updating widgets and wallpaper, they do make the phone funner.. but why need gps on when not using, or bluetooth, or wifi? Just simply turn them on when using...
So much going on with this phone I can say its good pretty decent battery....
Anyone know how to make my gmail sync every hour instead of instantly?

When I got my Nexus my battery was just as poor, but after using it for a couple of weeks I'm getting about 10 hours usage with medium brightness, WiFi, and gps.
So just give it some time and it should fix it itself.

Your phone or battery is defective. Call HTC for a replacement.

Wlan when standby and battery when not using

Does enabling wifi when on standby drains battery, even if you're not connected?
I made some registry changes yesterday and I also enabled this with wifi, and I woke up with 20% less battery, normal for me is 7-10%.
I can't figure it out what I did wrong except if wifi is the problem?

yes if your wifi is on it will consume more battery. check if your mobile is constantly checking for new mails or updating the weather. disable them if you want your battery to last longer.

I would like to disagree completely. I've already ran rigorous test just to prove if it does or not on MY HD2. And let me tell you that it does not. YMMV.
It eats just as much battery as if you're using it but without the display on. So in any case, it eats less because the backlight remains off.
Using DsE V6.5 ROM. I got my battery to drain 3% every 12-15 minutes leaving Weather to update every 30 minutes and Send/Recieve new Mail every 5 minutes, Have pandora playing in the background and leaving web browsers opened, google maps activate.
During my test, I recorded the time and the % drop. I started at 9AM @100% and Dropped to around 3:30PM to 7% battery left. Now remember, this is a constant run without turning the device off, never turning wifi off and without exiting any windows. Also, Ive set my device to dim the screen after 1 minute and let it blackout after 2 minutes. Just take note that every time I picked up my phone to change a pandora station or read a new email, I never push the "end" key to let the screen go blank instantly. I let it do its full 2 minutes thing and let it go blank automatically.
This is just so I remain very rigorous!
This has helped me understand a lot about my battery and how much I can pull it out during a full days or usage.
I noticed that My battery can last up to 6.5 hours of basically, NON-STOP usage. Just image if I turned off wifi and only needed it the moment I wanted to check if i had new mail, etc. My battery would last ALL DAY.
FYI, under normal use, my battery is around 55-65% by the end of the day under moderate use.

I have updates every 6 hours for weather, but I can see it connects to 3g when is the time. This is not the problem.
The problem started yesterday/today when I made some registry changes...I enabled 24bpp colors and I turned vsinc off.
I am not connected to wlan, it is turned off, I only enabled the option "enable when in standby" if I sometimes need it when phone goes in stand by.
I am asking...does enabling ENABLE WIFI IN STAND BY eats battery when NOT USING WLAN AT ALL?
Thanks

[Q] Battery problem, stand-by

Hi all. Here's the thing. Yesterday i've charge my galaxy (up to about 90%) set up alarm for morning, and going to sleep. In morning my battery was empty, i don't have idea why, because i push power button to "sand-by" on my phone in that night. What's the deal? Stand-up time was about 7h - is there any fix for that, or maybe it's some kind of bug? Oh that was my first stand-by mode for so long time (phone is pretty brand new, about 3 days from purchase)
Few words about phone:
-i9000XXJF5
-no root, flash, and any modyfication
-in phone i have about 20 instaled apps, 4 widgets on
-no task killer
-about 3 days from purchase phone
-home screen set on LauncherPro
Any advise guys?
Sorry for my english.

There must be some app draining your battery. My SGS usually drops only 4% in battery percentage during the night (I turn of 3g at night using SwitchPro, and I'm on JM2).

Have you installed the latest Facebook for Android app? It drains battery a lot because it keeps the phone awake 100% of the time. Uninstall it, or at least Log out from within the app, so that your phone can sleep in idle mode.

Yes... the problems of Android... I use CPUMonitorMini to keep an eye if any apps go rogue and start hitting my CPU 100% and draining my battery dry.

how long your battery used? if >2-year heavy use, could well be battery degrade. no solution except for buying a new one. (symptom: battery charge sudden drop, like 50% -> 20%).

For me battery drops can sometimes happen when I don't charge battery to 100% - so it's good idea to always charge to full.

First of all you should check if your battery is going into deep sleep mode. You can do that by installing Bettery Battery Stats, and leaving your phone idle with the screen off for some time. You should read the forum post to understand how it works. If after leaving your phone on "stand-by" you realize that it's not going into Deep Sleep mode, then you should find out what is keeping your phone awake.
I used to have the same situation as you, and it turned out that I had set the WiFi Sleep Policy in Viber to override the Roms setting, and consequently leaving my WiFi always on (which prevents your phone from sleeping). After fixing the issue in Viber my phone now turns WiFi off after 15 minutes of leaving my phone idle.
Now unless your battery is actually dying on you, I'm sure you can get a better battery life. I am using Tasker to program my phone to turn WiFi off when I turn off my screen, and then turn it on for 1 minute every 15 minutes during the day, and at nights it does the same thing but with an interval of 1 hour and half. There are apps in the Play Store that do this too, I've tried these both, and they work as they should, and they can even control your Data connection

Deep Sleep Battery Saver
All in all I've been losing an average of 1.7% during the day, and 0.7% and 1.2% per night. My battery currently lasts about 2 days on one charge. This is all assuming it is actually your WiFi that's preventing your phone from sleeping, I just figured I'd share my experience in case it is in fact that; the important thing being that you could probably get the same results as I have (or even better, considering your battery isn't busted) if your phone is actually going into Deep Sleep.

Verizon S7 Edge Battery Life Terrible

And there's nothing I can do about it. I only have a gear s2 connected at all times and wifi and mobile data off whenever possible. Before I leave to the gym battery is at 44%. After the car ride there it drops one percent. I unlock the phone, connect my powerbeats, and open youtube and there go another 5%. After a YouTube video there is 7% drain. About a 10 minute video too. Leaving the gym and hour later and I see a maybe 20% battery loss. I don't know how people with regular S7s get 4-5 hours SOT because I get only 3.5 maximum. I bought the edge looking for better battery life but it's practically no different than my S5. If anyone knows a magic trick to this, I need to know now because this is extremely annoying.

IF you got the device from an official retailer, just return and get a new replacement. Losing 7% watching a 10' video is not right even with max brightness. You can fix the standby drain by using Forcedoze (which helped reduce my standby drain by 50% to about 1% every 2 hours). 3.5 hours SOT is terrible even with max brightness. Just get a replacement please. It's not worth the time and frustration.
IF you don't have the option of getting a replacement. Forcedoze can help with the standby drain. Factory reset, set up normally (personally, I just turn off bluetooth NFC location and turn them on when needed), and hope that your terrible screen on time is software related.

Do you think it might be my location by any chance? Maybe the service in my area causes this drain. I also have gps on because of my gear s2 but I can turn that off and see what happens. GSAM tells me the in the past 30 minutes the drain rate is 15% per hour. I browsed the Internet a bit and have been using it the whole time. I'll try to also do a full battery drain test on geekbench with full brightness and see what it tells me.

It's a good possibility. I have a fairly weak signal where I am most of the day and only get about 4-5 hours of SOT. I have all radios off except WiFi and data when needed. Still with my usage I only charge every 2 to 3 days. I don't get the drain like you do from watching youtube though.

My battery life also sucks. I barely use my phone during the day and it almost dead when I go to sleep. Most of the day I am connected to wifi between my work or home. My old htc m8 one could last 40 hours. I think part of the problem is because I do not have root on this phone. I kind of regret switching because I cannot get root. I cannot use applications to adjust cpu or control my wifi, data and to turn off apps from starting automatically. I think tonight I am going to try and calibrate my battery.

I had horrible battery life after taking the 2 OTAs. BetterBatteryStats would not report the device going into deep sleep at all and I was losing about 10% per hour on standby. I did a Factory Data Reset and all the problems cleared away. BBS is reporting deep sleep after about 5 minutes of the display going dark. I have Wifi, data, Bluetooth, and high-accuracy Location services turned on at all times. I lose about 2.5% per hour now with AOD turned on on standby.
Guess my advice would be to due a FDR after every OTA....

Guys, I had terrible battery life when I first got the phone. Off the charger at 6am, under 20% by 5pm... Follow my steps below and I bet your battery will do a 180 and be very nice. Mine gets me 35-40+ hours on a charge.
Disable the bloat apps you don't want in app manager.
Turn off Google usage and diagnostics reporting for the Google app, and if you use the Google keyboard, there too. This and the next one were the biggest improvements by far.
Turn off Samsung "Send Security Reports," and in the same place, turn off auto-update Samsung security updates.
Turn off device/Bluetooth/WiFi scanning.
Set keep WiFi on during sleep to while charging.
In permissions, I turned off location for any app I didn't think needed it. I went from 30+ to about 15. If an app requires location to work, you will get a popup warning when disabling location for it.
Lastly, I did a Restrict Background Data on several apps I didn't think needed it.
My phone started dozing and the battery drain dropped way out.
I keep AOD and Bluetooth on at all times and connected to my smartwatch all day, and my car about an hours a day.
Hope this helps! Apparently out of the box the S7/Edge battery life is terrible...

I installed forcedoze and did the adb non-root command and now my phone's battery is holding up better. I think the phone was just sleeping.

It's ridiculous one has to do all this to get closer to acceptable battery life.
Google and SEC should be ashamed of themselves!
It's not just VZW devices either. AT&T are just as bad.
I've given up on trying to get acceptable standby drain and just let the device live on a wireless charger.

You need to turn off all radios when you go to sleep for the device to enter deep sleep. I had the same problem and when I started turning off wifi and mobile data for the night GSAM reported deep sleep and I was only losing 3% per night.
