[Q] What is acceptable 'up time' for the Note?

I've had the Note through GB, ICS Stunner and now official ICS rom....
Stunner was definitely better for battery than the official ICS rom.
I unplug my phone at 6.30am and put it to charge every night around midnight, with battery usually nagging me to charge it - about 10% or so...
My question is that normal? I use my phone normally, the odd facebook and twitter time, a bit of note taking, internet etc...
is 17/18 hours as good as it's going to get?!

yes 18 hours is good, consider the size of the screen etc and how you use it

Mine dies in 9 hours with Wi-Fi on and Auto Sync on. Is that normal?

I would say yes. WI-Fi on means constant power consumption. Auto Sync on means even more power consumption. Wy do you leave them on? You can synch when you need to and switch Wi-Fi on when it's necessary.

Mine is always on wifi and last about 2 days... ^^''

Stunner averages at 16-17 hours, and most people get 17-18 hours if you look at the stunner thread. The best battery life was on stock GB though, 40+ hours for me (light use)

I would think so too with GB...thats what I'm currently running. =)

Measuring total uptime (from charge to charge) doesn't make much sense IMO,
because we all have different usage habits.
Screen on time, however, is a different story.
Anything less than 4 hours of screen on time is bad in my book.

I'm running the german ICS now and after a few tweaks (autokiller) .. i get 2 days of power :d thats with wifi off at work and at Night .. an hour of playing games.. half an hour of voice Calls and some music listening + web browsing. I'm a happy man
@chasmodo: i do listen to music lots with the screen off so screentime is not an absolute measurement of usage either ...
Cpu states However is a very good representation of usage .. minutes 1400mhz..200mhz..Deep sleep ...

Im using LPY rom and for me thet battery time has actually improved compared to official GB. I keep wifi on 24/7 and 2g mode / powers saving, gps off, so on avarage use of around 8h daily, i get more than 24h in one charge.

Yeah since I've done the flight mode and battery pull my up time is amazing! Been on 9 hours now and lost 30% of charge. Very happy with it..

17 hrs so far and battery at 65%. Auto sync, wifi, gps, BT on. Too lazy to turn that stuff off.
Nothing special just stock ICS.

i can only get 16-20h tops... with texting, some calls, gaming and wifi :/ but i've only made 4 charges to the battery yet, so hope that life time will grow up.
using it for about 10h now, and bat @ 55% runing 4.0.3 german ICS

I get more than a day with moderate use. Lots of wifi, FB, a bit of browsing and gaming, some music, a lot of texting and whatsapp, a few calls and just playing around scrolling between homescreens and stuff. Pretty good to me!

I find I get on average 16-20 hrs with good use. It really depends on the screen on time as it sucks up most of the power. White especially uses up the most power on these screens. When I check battery stats I usually average about 3-4 hours of screen on time and most of that is web browsing and checking email. Your mileage may vary if you've got background processes
At idle, I lose about 1% per hour (sometimes less if i disable wifi/data/gps/sync). So theoretically I could get over 4 days in idle. With the display on constantly I would guess it would use 15-20% per hour. If you're playing a cpu intensive 3d game you can probably double that or more!
I found cpuspy really helpful in diagnosing battery issues. I was suffering from the deep sleep problem when I moved to ICS LPY (the sounds off/airplane mode/reboot fixed it). The cpu never went to sleep so was eating up at least 5-8% per hour. It might not sound much but if I forgot to recharge the phone at night I would end up with a dead phone in the morning!

Those are still good numbers but from those pics your posted, where the graph goes up it looks like it was charged partially at least twice. Connecting it to any usb will charge it. The battery hours display only resets when it has been fully charged.

Over 24 hours

[Q] About battery life test and reality...

photo sharing
I have seen before those result and now I ask myself that is my n7000 can 12 hours 47 minutes screen on really???
Today, my phone screen on time is 2 hours and battery 25%. How can the testers do that, even with 3g???

Battery life varies tremendously between ROMs, settings, apps installed and running, and usage profiles. Don't take these comparisons so seriously. Anyway, 12 hours of screen on seems a bit exagerated to me. If you feel your battery is draining fast, check:
1) Is your ROM and kernel a battery drainer? Check the forums.
2) Install an app like Better Battery Stats and check if your phone is going to deep sleep, and if there are too many kernel wakelocks. It could indicate a kernel bug (old ROMs) or a misbehaved app.
3) Install an app like Juice Defender to save some battery, reduce the brightness to minimum etc.

2 to 4 hours of screen on time is more common, but 12 hours is too much for note.
Maybe it is standby time?

I think so

12hr 3G talk time .. hahah .. that is a joke ... did not happen to me a single time through all my cycles of of ROM's since its purchase.
3 - 4 hrs continuous 3G talk time and your phone battery icon is just about to turn Red

you can get a very long screen on time if you set a pureblack picture and have all radios off lol

Odp: [Q] About battery life test and reality...
The longest screen on time I've had was during battery comparison - 7:40 of continuous video playback with minimal brightness and in plane mode. I guess it could get a,bit better for book reading or some similar low-current activity.

[Q] 4 hour battery life on heavy non gaming usage

i am getting 4 hours tops of batterylife on my z1
i have maximum brightness auto turned off i have wifi and bluetooth off
i have a live wallpaper
i have skype steam running in the back
it takes 2 hours for it to drop to 50 and 4 hours to 0 from full charge on pretty much full on screen time
is this normal even on that kind of heavy usage

I would recommend using wakelock detector to see what's really soaking up your battery. It's a free application and it's pretty self explanatory. Charge up your phone and use it heavily again and report back to us with your findings through wake lock detector.

Have push mail on ? My phone was empty very quick before the update .257 but now its much better.
I think if you mean with 4 hours onscreen it is normal otherwise it is not.
Use wakelock detector already mentioned

4 hours on screen time with full brightness sounds reasonable. I can play heavy games for about 3,5 to 4 hours with medium display brightness.
Always keep in mind that the display is the biggest power consumer in modern Smartphones.

so the battery really is that bad?
using stamina it drops 20 or so % during the night

Actually the battery with its 3000 mAh is gigantic. And I think 4 Hours of heavy usage with full brightness is ok.
20% over night with STAMINA mode is too much though.

i have steam and skype whitlisted in stamina
really dissapointed in the battery life then
i guess theres no such thing as a full day of usage then
is there any smartphone that can handle that?

Do you actively use your phone all day (screen on all the time)?
With medium usage (WhatsApp, Surfing, Some calls) I can go for at least one, maybe two days.

I slept for 10 hours and my battery drained 9% with wifi and GSM on from full charge. your using the stock charger right? charging faster then recommended will reduce the life of the battery and can cause this kind of issue, but the phone is so new i wouldn't expect that to be the cause. I know the stock charger 1.5A. With a 2A charger it is likely the phone will charge at 2A.
Its probably a software related issue your having, but 20% overnight seems like a lot..

I would something is hitting your phone for wakelocks. 20% over night is a bit high. I know google currents is a know offender so uncheck that if you have it syncing. Try turning off google location access. Turn off gps and nfc. Using you phone at max brightness will always be very draining, leave on on auto unless your outside in daylight or in the car. Facebook is also bad for wakelocks. Any app that is polling for updates will be hard on battery. My experience has been a much improved battery life over my previous devices. On an average work day I leave at 8 and get home at 430, and I usually have 70-75 % by bedtime usually around 30%. I leave most my apps syncing all the time as well. I know the phone is new to you so I would say you might be playing with it more than you normally would.

I suspect that steam / skype will be preventing the phone from ever going to sleep.
I would suggest capping the max frequency of the cpu to quite slow or setting the governer to a conservative level (an app could be forcing the cpu to stay at a high frequency most of the time which will just drain the battery in no time)
However this usually requires a custom kernal or at least root which isn't very well developed on the Z1 yet.
If you can run a wakelock program that also logs the time spent at each cpu speed ... that would help people help you ...
As for any phone being able to handle it, unlikely the battery is relatively large but so is the screen, most phablets have only a fractionally bigger battery.
Only a full blown tablet will get you a much bigger battery that might be able to last you twice as long.
I typically go 3-4 days between charges on the .257 firmware without stamina mode and paired to a smartwatch 2.
I used to get 3 days on the 534 firmware with stamina mode! (i work in an area of very weak signal so i get 25% no signal time over a battery charge)

Bad Battery Life?

Hey guys, I've seen posts about people getting amazing battery life, both on stock and on a custom rom. I can never seem to get the same results, whatever I do. Sometimes, I'll toggle a setting and I'll see improvements for a day or two, then it goes back. Even more frustrating is there have been times when I turn the setting back to what it was and see improvements. It was like this for a while, but recently I've kinda gotten stuck with ~15 hours from 100% to 10% and nothing seems to change it. I have location on device only (its for weather, battery saving seems to be worse because Google services just syncs all the time and eats battery) and mobile data on. I've disabled pretty much every Verizon app and I just use moto display and the sleep thing. What else can I do to get better battery life short of a custom rom? The only reason I won't do a custom rom is because my parents won't let me spend $25 on sunshine, whether it's their money or mine.

I exactly get the same results as you. I'm on stock and disabled all verizon apps. A help could be really nice.

Keep in mind that battery life varies GREATLY upon usage. I can kill my battery in a matter of a few hours or have it last for nearly a week. Sync frequency, sleep time, connectivity, refresh settings, screen brightness, CPU usage, vibration on/off, number of wake locks...I can go on and on.
For example, I had my S4 last 5 days before it dropped to 80%, as you can imagine I didn't use it much. However, that same phone died in probably 3-4 hours on me also.
What matters most is if you have more battery life than your previous phone. Never compare your battery life to others.

I included some usage statistics in the ingur link. A lot of battery seems to be used by Android os and android system. Is there anything I can do to lower this?

What do you have your screen brightness set to? Your phone looks completely normal in terms of battery usage (Android/Google will always use a couple percentage).
Try turning off adaptive brightness and putting your device to the lowest brightness you can stand, that should add at least another hour or two depending on your current settings. 3 hours of SoT over a days usage with what looks like moderate use (YouTube, Messaging, etc.) isn't too bad for this phone.

Thanks for the advice! I guess I was expecting too much out of this phone Oh well, i'll just wait until i can get $25 in amazon or google play gift cards to pay for sunshine so i can get computerfreak's rom.

I am on CF's latest ROM and I'll say my battery life improved compared to stock, but not by much. I may get 6 hours SoT but my battery is down below 20% by the end of the day, and that is if I avoid playing games. Playing games all bets are off, the battery runs out quick.
There are some out there saying they get 8+ hours SoT and 48+ hours between charges. I call BS on that unless you are running minimum brightness and not doing any syncing or anything location based, and possibly even turning off cell data. Showing off with pictures of their battery stats and not telling the whole story.

If you unlock with Sunshine and install RR, you can use the custom kernel to tweak the CPU and GPU frequency to save battery life.
Additionally, there are other ways to save battery, like adjusting the pixel density and colors. (At least I think so?)

Greenify also helps. I think that is available for non-root as well.
Also, check your wake time. If always awake, could be the Google services running constantly trying to update.
There is an app to fix that, but I think it requires root.

also, my phone really likes to shut off before it reaches 0% battery. Is this normal?

I doubt its normal, buy I have noticed that mine does that too. It usually shuts down around 7% without warning.

Is this normal battery behavior?

So taking a look at my screenshot after a long 14 hour work day I'm down to 35% yet with only 1.44hr of OST. I've seen numerous reports about 5/6/7 hours OST but the most I've gotten was 5 hours and change with the battery all the way down to no more than 10% and that's with battery saver automatically activated at 20%. I do not have force 90hz on anymore for the past week and I'm currently rooted in December patch stock kernel and minimal magisk modules installed. Running substratum of course and Viper. Nothing else really fancy going in with my setup. Been eyeing down better battery stats and nothing is hogging battery consumption in the background. Any thoughts on this would be very much appreciated. And yes I'm aware of the disappointing battery size but I believe I should still be seeing much better performance than this.

It's normal for a device with a small battery. Check if you have any wakelocks and start carying a portable charger

Do you have the P4 XL?
I'm on force 90 hz, mobile network all day, 90% brightness level, rooted with magisk, only thing I'm not using is motion sense (not available in my country and don't want to force it with any module yet) and get 6-7 hours SOT easily

You "Full charge lasts about" is still a decent 19 hour and 15 minutes so do you always end around 35% and under 2 hours SOT? Do you stream something with the screen off most the day?

I'm always checking for walelocks and I have nothing abnormal going in there and I even have a dozen apps battery restricted

FFS, don't believe the stupid train on SOT being a remotely valid indicator of a device's battery life. your SOT will never match the next person's nor will it be a reliable indicator that you'll get that amount the next day. you should be measuring your battery drain rate and determining what's causing your battery to get eaten up through the day.

I do agree that SoT is not a good indicator. For starters, a device with a screen at 100% brightness doing the same workload as a device with a screen at 50% brightness will have wildly different SoT. The SoT is only perhaps relevant to you individually, and only after a long time of use when enough data was gathered for you to know the actual average SoT.

I mean my full charge lasts about 16 hours, but yet some days get 7 hours sot and others 3, it's all in how you use it. I'm still stock and haven't rooted.
