My note 9 is a week old, but I'm no where the statics says about the battery life, I have iPhone 6 and it hold the battery better than my note 9, my usage is really under average I wake up 7 am with 100% I reach home back from office with 13~10% left , and I really don't use the phone at all, you can say that I use it approximately for 30 min through my whole day my iPhone 6 is at 71% with same usage and my iphone was charged two days ago I have no clue what's up with my phone, I disabled sync, navigation bar, nfc but no luck .

Leave off charge at night and see how much battery it uses during the time you are sleeping. Report back.

Just FYI, signal strength is probably one of the biggest influences on battery life. If you're in a concrete building where the signal is very weak, the phone could be constantly polling for a stronger/closer tower. Using WiFi at work, if available, will help mitigate that.

7 hours sleep lost 20% flight mode is off, I still think 20% idle is very high

That is high, i had same issues.. i was losing around 40% over 12 hour period! 4g on Sync On that's it everything else off..
My NOTE 9 was only few weeks old come to week 4 i had a replaced.. Before having it replaced week 4 battery got much better i was losing around 4-5% over a 12 hour period.
i still got it replaced, one thing I’ve noticed it seems like Note 9 is learning your usage pattern.. Your battery will settle down, you just have to give it time.. Samsung usually offer 30 day replacement! so wait till you get into your mid 20s days if the battery isn’t normal get it replaced!

You definitely have a rogue app or something, I leave home with 100% and use the phone a bit and i have 80% odd when i get home, install better battery stats and check what's consuming your battery.

yes, install the app called better battery stats and let it run for a day, and see which app(s) or process is consuming battery.

Just an observation in regards to deep sleep and signal strength. I've noticed if I place my note 9 in an area where I have the best signal before I got to bed , then less wake locks appear to occur. I've tried this theory a few times.

The absolute max should be 7% for 7 hours (1% per hour drain) and most of the time it should be around 3-4% for 7h. Most likely you have a rogue app on your phone that is causing the issue or you used package disabler to disable some packages in the operating system.

How often do you charge your nexus per day?

Like the title said. How often do you charge your Nexus 4 each day. Pleas take into consideration that you let your N4 run at least under 30% before charging. If you can go on without recharging your battery for more than one day please post the numbers of days.
I charge once a day. I get 12-16 hours of battery life from what I consider an average day attached are screenshots from yesterdays battery life

3 times, but I just got it 2 days ago. It might be that new phone usage spike. Still, I have serious doubts that it will go to less than 2 charges per day

Yep, same. I've even had 40 hours out of it once, but only because I was in meetings for 2 days and the screen was off for 8 hours at a time. that was fully charged to completely dead.
Really happy with the battery life so far, I was being conservative on my last phone with battery however now I've got this I don't really think about it so much.
Charge when I go to bed.

I got my Nexus on Tuesday night and I'm only just charging it for the first time now.
I'm only a light user though.
Once - Over night
Last's all day wifi on 8hrs - BT 1hr - texting & a few calls
Depends. When I'm at home I charge once per day, but when in at work it just sits on my desk charging. I normally use the phone more at work then I do at home, so it's hard for me to tell if I could really get through a whole day work my normal usage. I have done about 12-14 hours or so with a couple hours of screen time and still had 15% left. To me, the battery has been about 25 percent better than the gnex.

I still love my Nexus 4 and it performs well still but the battery life is now beyond dire, charging it 3 times a day.
Is it worth paying a firm to replace the battery? My thoughts are that I can just put that money towards an inevitable replacement in the near future.

I just replaced the battery in my N4. It was simple, requiring only a small torx driver and a small Phillips, plus a pry tool. The battery was cheap on Amazon and says it is an LG battery.
The old battery would no longer charge at all.

I still get 4h of SoT, and 10-12 hours battery time - so I am still quite happy with my N4. Unfortunately the camera really sucks (even more now) so I will replace the beloved N4 soon.

Yeah, I am having intermittent camera issues, a lot of photos come out black even in good light.
It's another excuse to upgrade I guess, has been a great phone though.
I think I should try the battery swap thing, mine just cannot get more than an hour and a half of SOT no matter what combination of ROM, Kernel and Android version I try, and using it during my daily commute means I arrive at my workplace at already 60% even if I'm on extremely low screen brightness. Greenify doesn't help either because it's the actual screen on what kills it, as long as the screen is off the battery drain is negligible.
Worst part is that every single battery out there is a fake, just with a very high-quality copied sticker on it. AFAIK the only way to get a new original battery is through LG and for a price you'd be better just getting a new Moto E 3rd gen for a little bit more and call it a day.

I have decided to give it a go, what sort of screen time is your replacement battery giving you, was the battery from an Amazon Marketplace seller?
almost all day pluged on computer lol

Poor battery life?

I have an iPad 3 and a rooted Nook with CyanogenMod on it. Both go days and days on standby, meaning fully on but the screen just off. My N7 which I just got a week ago is totally dead after 24 hours, even if I have not used it at all.
Is this normal?
Mine lasts about two days with minimal use.
Make sure wifi is set to sleep while screen off.

You need to get something like Gsam from playstore. It may tell you if an app is draining your battery severely, or if apps are waking the tab too much.
Also, Cpuspy will tell you if its going into deep sleep. On playstore as well.
Those will hopefully tell you why your battery is draining. I charge my N7 about every other day....maybe 3. Its mostly used to read books, and sometimes some games. So definitely not heavy use. But standby, about 1 percent lost overnight.

Not normal. Just did over 3 days with 6 hrs screen on time. Turn wifi off when screen is off and make sue you dont have any apps running non stop. Better battery thats is a north app for this. Check the partial wakelocks

Hmm ok, I will try to figure out what's going on. I am using MightyText... could that be it?
That not normal at all try suggestions above, mine drop only about 0.2% per hour on standby with wifi-on and screen-off.

Mine takes 2 to 3 usually. Are you using the cable and charger that came with it? If not, that can play a roll. Also, if something greedy is running, can slow charge times too.

Mine drains pretty quick when in use, but if idling, it lasts a very long time. I've seen it not drop 1% until maybe 2-3 hours idling. Heavy usage drains like 1% every 10-15 min.

Same here. Idling last night at 70%. Woke up 7 hours later at 69%(airplane mode) but as soon as I start using, drops super fast.

I think it is MightyText. It seems if I get a text from someone I have not received a text from before it opens a window on the locked screen showing the text and then the screen never goes back to sleep. It stays on until the battery runs out. If I get a text from someone I had a conversation already going with this does not happen.
Pretty weird but it explains why it is totally dead when I would get home from work.
I had poor battery life too,but I've done something that someway fixed that.
I format system etc and reinstall 4.2.2 stock with stock kernel.
After some charging circles here the results
i know if you leave skype on it drains an insane amount of battery...so i keep it logged out now whenever I don't use it
I would have liked to see the main battery status page. See if you did anything with it, or just kept the screen alive for 9 hours? LOL.

Nexus 5 battery life

For anyone that's interested, this is today's battery life on my Nexus 5. Came from a Galaxy S4 and I must say, I'm impressed.

Wi-Fi connection the whole time?
Sent from my Nexus 7 using Tapatalk 4
Man!
Almost 7 hrs of SOT... Thats Frigging AWESOME! Can you tell us your usage patterns? What was enabled/disabled...? Majority time on WiFi or Mobile Network (2g/3g/HSPA/LTE). Signal Strength of the Carrier
On my N4, the highest ive gotten is 5 1/2 hrs of SOT and that is with most of the stuff disabled and on wifi!
Whoa! At first 11 hours looked bleak, but 7 hours of screen-on time sounds fantastic! :laugh:
Wifi on the whole time or not.. 7 hours of SOT is impressive.. especially on a 2300mAh battery
as a current S4 user, seeing things like this is making me really impatient in waiting for the N5! i could barely get 5 hours SOT on an AOSP rom on my S4 or even on TW and this was with greenify and auto sync off at night.
really hoping that once I get my N5 average SOT time will be 4-5 hours as thats all i really need to be satified

What screen brightness setting are you using? I barely hit 3 hours of on-screen time on my galaxy S3 so this looks really good! :good:
The most screen on time I used to get on my S4 is 5:30 with wifi only use. That number has dropped to 4:00 now on wifi and 3:00 when I am on LTE for pretty much the whole time.
This battery life is impressive to me and seeing the camera comparisons between nexus 5/S4 and having the Nexus 5 win has solidified by decision to get a nexus 5. Now if only I didn't have to wait 3-4 weeks...

Few questions:

2) Do you have sync on?
3) Do you have facebook/twitter/instragram...etc?
That looks amazing. Also that resolution on the screenshot....

Hey mate, that's a miracle, the curve goes even up at times :angel:
You obviously made some micro-charges during the day, you cheeky troll
For the first charge out of the box, should you charge the device on or off in order to get the best out of the battery as well as improving battery's lifespan? Cheers
Sent from my Galaxy Nexus using Tapatalk
Those two little bumps where it goes up in charge I think are where I had it plugged into the pc to transfer stuff across.
Anyway.....
Wi-fi was on all day apart from a couple of occasions where I went out for a short while and it was on H+ (full signal)
Google Now is disabled.
Sync is enabled.
Screen is on auto-brightness but my living room is fairly bright and so I'd guess at the screen being on 50-75% brightness all the time.
Those 7 hours of screen on time were pretty much all down to browsing on Chrome and aimlessly scrolling on Facebook.
I'm very impressed with this phone (even though my power button rattles) and at first didn't know if I'd made the right choice ditching my S4 to get it, but after having it since Friday I'm glad I did now. Another thing, the signal is great. On my S4 in the gym I used to get 1- 2 bars of 3G signal at best, with the N5 I get 4 bars of H+.
For anyone thinking about getting this phone, you won't regret it, especially if you're not a fan of having to charge your phone at 3pm because it's dead.

I ran it down Friday and charged it overnight, then ran it down again Saturday, charged it over night (both times 0% to 100% and both times whilst I was in bed I left it switched on but in aeroplane mode) and this was the result on Sunday's usage.
Did you put the charger twice?, the charging bar is empty, but in the graph there're two times it seems it was charging.

Thanks, nice results though!.
I've seen multiple devices I've owned including this one where the battstats go up in tiny peaks without me charging it. Just saying, it happens even if it wasn't plugged in to PC. If u were in the PC we would have seen the charging bar wouldn't be empty. Its almost like the battstats graph predicts usage and where the batt prolly will fall to but then if u stop using it it goes back. Idk hard to explain.

Something I was looking forward to. This suggests the Nexus does have great idle time. And the drain is mostly because of the screen. People are expecting magic with such a screen I guess.
I have been using for the last two days, haven't cracked 2.5 hrs on screen time.... I need to keep tweaking

not sure if this will make a difference for you but 3 things that i did is getting me 4+ hours a day screen on time easily. turn off location services completly (just turn them on demand if prompted), disabling google now launchers always listening option, and my personal best fix, disabling tilt scrolling in the chrome browser. tilt scrolling is a little janky atm because it never actually shuts off, so chrome is always registering any device movement in your pocket or whatever even if the chrome app isnt even open, and disabling that helped a TON

Mine has been great today. I have gotten almost 4.5hrs screen on time and I'm still at 38%. That's with stock rom/kernel and Google now and sync on. Granted that today's usage was mostly on WiFi by it is still much better than my N4 was.

is it normal to have only about 4 hours of screen on in xperia z1?
how come because it is a 3000mAh battery?
or is my battery a faulty one?

I'm not sure if its true but I've heard people talk about it. Do what I do, go under developer options and limit background process to 3. Make sure stuff like nfc, bluetooth and gps are off too when you're not using them and don't overcharge the phone

I get 3/4 hours of screen, never got more than 4 and forget 5. Who get 5 or 6 I just don't know how they do that, maybe as I am on 4.3 and not on 4.4 but to me it should not make any difference.
Probably, as the phone is assembled with different hardware pices, like 2 lcd models, then can influence on battery consumption.
Hi,
I used to get 5-6 hours screen on time, but then I started to use more apps and specially listen to more music on it, with 4 hours of music listening I was getting 4 hours of screen on time. Maybe you should try letting it get completely discharged and then charge completely while off. When I was getting a bad battery life it helped me .

Actually I do not complain of battery life when the Phone is in idle as I get more than 4 days in standby with a 30minutes on screen, what bothers me is the time on screen, which is no more than 4 hours. If you cannot get 3/4 days in standby then you have look for sapplication which working in background and eat your battery.

Dial *#*#7378423#*#* (*#*#service#*#*)
Choose Service tests
Go to Battery health test, then it should say if your battery is ok or not.

This is irrelevant as any time you log into Service Battery Check it change every time, it not telling you the right thing and the battery cannot be checked from that.

Actually I do not complain of battery life when the Phone is in idle as I get more than 4 days in standby with a 30minutes on screen, what bothers me is the time on screen, which is no more than 4 hours. If you cannot get 3/4 days in standby then you have look for sapplication which working in background and eat your battery.

Well, If i use the phone with 3 or 4 hours screen on time I have to charge every night, sometimes 1.5 day with 2 hours screen time. You mean three quarters of a day? I think I will not lost more than 15% if I leave it standby for 3/4 of day(maybe).

Then I don't know where is the problem.
In my opinnion this depends on how you use the 3-5 hours display time.
If they are continuous it doesnt use that much power. When i'm using it at work (don't judge me) i can get up to 6 continuous hours.
When im using it over the day (12-15 hours) i get around 4 hours and a litte more, wich is kinda "hardcore-user" for most people.
My nexus 4 never lastet that long, i could just get over 2 hours display time when i used it over the day and 3 hours at work...
I usually drain about 20% of the battery for every screen on hour (or about 5 hours of screen on per full charge), and that's using Facebook for a long time (a very well known battery killer).Even on my worst days, I never get less than 3.5-4 hours of screen on per charge. However, I tend to keep brightness very low.
Check the battery usage per application using either the built-in monitor or something like GSam battery monitor. You may have a bad application, or too high brightness, or even low signal strength.
