Hey,
I own 3 tablets and considerig the NC for the wife as #4
however I was wondering if anyone has done some specific battery tests for example:
1) How long from full to empty when reading a book?
2) On stand by
3) Off (you know you charge it on monday and dont go to use it until friday)
4) media play? (mp3, avi's etc)
5) light wifi internet use?
she will use it MOSTLY as an ereader however i will need to use an alt FW so she can load some of her nursing aapps (epocrates etc) but she HATES the 3 hour battery on her augen
For me, using strictly as a reader, it will last between 8 and 10 hours, depending largely on the screen brightness. For example, I have my screen brightness down to maybe 17-18% (roughly judging slider). I get around 8 hours there, but by setting the 'night mode', it bumps it up. As always, YMMV...
cool thanks
anyone else?

In my experience the biggest battery drain is WiFi so I leave it off most of the time. I usually leave the brightness at 25%. I also don't let the battery completely drain -- 10% is about as low as I go. So with those things in mind...
1. Reading: 9-10 hours
2. Stand-by: drops a few % each day
3. Off: I never turn it off completely but I would expect minimal battery loss
4. Media: I only play hardware decodeable media (MP4) and get 7-8 hours
5. Browsing: Not much experience but I would guess 6-7 hours
If you keep the stock rom, it would last longer. I have two. One is running cm7; and one is stock. The stock lasts way way longer.

I'm currently using CM 11, which is not yet stable on HTC One M7 GSM (currently on "snapshot"), and the battery life just kills me, so inefficient. I have an external 16,800 mAh battery and it does a good job eating through that too. 20% from that will give me 30% on the phone if the phone isn't powered all the way off -- that seems like a lot of usage (even if that external battery is used and only half that capacity now). I take measures to help my battery like auto brightness, turn off mobile data or wifi depending on what I'm using, or both to really save, I'm usually on silent, no bluetooth ever, location services always fully off unless I'm driving (rarely) etc. Just being in my pocket with a couple of hours or so total streaming music over LTE during the day the thing is under 20% after around 8-10 hours. A few days ago just a couple hours of music streaming (some downloaded some mobile data, not sure how much of each but still; this was not "screen on" time either) and an hour of web browsing ate 70% of it. It was 100% when I unplugged it around 6:30am and shy of 30% around 11am -- jeez!
I have been starting to think my battery is just worn out, I mean the phone is 2 years old (contract ends a week from tomorrow; it really is). But, what if it's the non-stable CM 11? Maybe a different ROM would help? I don't remember it being like this back on the stock ROM but it's been a while since then, and I remember being kinda frustrated with battery life every since I switched but I never got around to messing with this until now when I am even more irritated. I'm due for an upgrade, but squeezing some more life so I can wait another couple of months to see what unfolds (or change my mind entirely) would be great.
Can someone suggest some more efficient ROMs? I could handle Sense but I prefer AOSP -- whatever gets me more juice though. Or feel free to suggest other possible problems/solutions as well. In my power options in settings where it shows power usage, screen is always at the top with around 30%, so nothing jumps out there either. Thanks for any and all time!

I get the best battery life from Android 4.3 Sense 5.5
InsertCoin HTC ONE v8.1.3 >> http://insertcoin-roms.org/category/devices/one_m7/one_sense5/
It's also not real bad on AT&T Stock 5.12.502.2
I unplug the phone at 6AM and take it to work, normal use txt a few calls some web and emails and I have around 50% battery left when I get home at 3:30. On heavy use days I have about 30% when I get home. I should note my phone is also going on 20 months old.
My Tablet lasts 2 days before its totally dead with ZERO USE!
Updated to 5.0.2 as i hoped this would fix it. No change
Lost 10% battery while in power saver mode in a few hours!
Lags all over the place when scrolling, the play store is horrible when scrolling apps.
Right now my S6 has better standby on 4G and more life in use than my tablet has with no use!
Any ideas?
Can't speak for Lollipop, since staying with 4.4.2 and disabled auto updates. I only lose 2% in ten hours and the best Android tablet I have owned- especially in regards to low sleep bleed.
clearly something is not right have you factory reset it? That would be the first thing to make sure no apps are doing anything weird.
I flashed a whole new OS... should i wipe it?
You need to install a wake-lock checker, it will show how much time your tablet is actually in deep sleep mode, which uses the least amount of power, mine shows 97% time in deep sleep.
Some application can keep you tablet from going to sleep, alarm clock and sync can also, and apps/software you downloaded.
Do you get still get major battery drain after a reset, dont install any software/apps and the charge to 100% and then leve it for a few hours and then check how much power you have lost.

Over an 8 hour period (avg) with wifi on, my screen brightness set to 10-20 range (that is the brightness I prefer on my tab s), and with greenify I lose maybe 1-2% battery. You definitely have some program or service constantly running or waking up your tablet, and due to the interactive governor that samsung uses your tablet wakes up at 1.9GHz each time to be more responsive/save battery by handling what ever is needed as fast as possible so it can sleep again. Unfortunatly if some app keeps going "hey, hey, I am here, I need you tablet, hey, hey, ect........." that battery saving governor will murder your battery.
So i wiped and its still 48 hour batter!
Battery %bleed
Losing around 30% battery over night idle.
*wifi & sync on...

Do you need to have your wifi and sync on for business or something, if not turn them off, of use an app to to mange them like the free juice defender ect.
Just install it, make sure it is enabled and then make sure the icon is on your taskbar so it has not been killed, and them forget about it for a week and see how it goes.

for some reason on this tablet, wifi murders battery in standby. if you turn it off it lasts much better... but this tablet and this tablet only, leaving wifi on kills it horribly. but problem is, when you wake it for teh first time in hours and wifi activates, all of a sudden everything syncs and it's so damn laggy those first few minutes of use. it sucks. only this tablet. never had this issue with my nexus 7. that thing gave me 7 days stand-by time.

Try putting your tablet in airplane more overnight and see how much power it consumes. I lose 3% over 8 hours when I put it on airplane mode and disable wifi.
Im sorry but this is BS.
Its clearly faulty. its going to samsung. i demand a refund.
How much power wifi uses depends on the distance to the router and how much interference it has to try and break though to get a good connection which means using more power, that is why wifi uses more battery power on some peoples tablets than others do.
John.
disregard.. just realized my screen shots were messed up. I'll post my standby time tomorrow.
Here is a very simple stock no root mini guide to getting 1-5% loss over an 8-10 hour period while sleeping or at least while the tablet is asleep.
1. Install greenify even if you are not rooted and even if you do that have the donor package there are many many apps that do not like to sleep, greenify will fix that for you.
2. Unless you are a Doctor, CEO, or someone whose very life hangs on getting the latest cute cat post while you are asleep try to adjust your sync times from under an hour to as high as you can. (If you are turning off wifi then it might still matter if the app wakes up your device just to see it can't sync)
3. Samsung has given you a very nice QHD screen. It is high resolution, Amoled, and other nice rhings but while you sleep you can not see it so turn the brightness down before you touch the power button to 5-15. If you wake up in a dark room and need to use your tablet that level of brightness is far kinder to your eyes and even kinder to your battery.
Just doing this generally kept my battery usage down to only 2-4% per night, of course then I rooted my tablet and installed TW detox 3.0 and now it is closer to 1-2% per night. Try any or all of these and I hope it works out.

losing 48% per day... screen brightness wont help will it when screen is off all day
Screen brightness is for those times that an app wakes up the tablet and turns on the screen to tell you something (new email, facebook wall post, new cat video, ect....) and yes it helps.
If you are losing 48% a day then you have some app doing something that is keeping your tablet awake for a good portion of the day. Or you have a defective battery/tablet. I can surf the web for a good portion of the day and maybe lose 48%.

Are you rooted. It's sounds like you have some wakelocks? If rooted you should use greenify and a wakelock alarm to fix the problem.
i'm curious to see what apps and how many you have installed. Can you post screen shots of your app drawer?

what email apps and cat video watching apps are you using that turn the screen on? no app that I have EVER turns my screen on at all. the only app that does that is on my phone, and it's from textra, an sms app that isn't on my tablet.

I'm having tons of issues. The camera is super laggy. The battery is draining extremely quickly. The phone also requires me to hit the power button 2 or 3 times to wake from sleep.
Right now id like to tackle the battery issue since its making the phone unusable if I take it outside for more than 3 hours. Last night I left the phone with its screen off all night. The battery went from 85 to 25 in 7 hours. Not sure what's going on. I looked at cpu spy and the phone is not going to deep sleep at all. Anyone know what I can do to trouble shoot this? I got the phone from eBay. Its running nougat. The first thing I did was flash it with stock Rom. Factory reset has been done also wipe cache. Thanks.
Here's a screen shot of cpu spy.
I don't particularly have an answer either but for what its worth I've been having a similar issue with my s6 edge although the battery wasn't the greatest even before 7.0 I also feel like the upgrade did make it a little worse too. I always have power saver on and i still have to charge it mid day (sometimes twice) if I'm running around anywhere, it'll go down about 10% even just during my 15-20 minute drive to work in the morning
Morning all.
Something that has been slightly bothering me since I got this phone....it has a massive battery, it can be heavily customised with roms, xposed modules, magisk modules and all manner of tweaks. Probably one of the most open and dev-friendly devices I've ever had.
Yet, no matter what I do the only way I have ever been able to get more than 2 days out of a battery is to literally not use the phone.
I have had devices in the past such as Xperia Z3 Compact, S7 Active and others with smaller battery that were easily able to push 3 days with regular use. Hell, the Z3C was able to get up to 5 days with a little bit of trickery turning off radios when not in use etc.
Is the extra diagonal inch of screen realestate really enough to destroy the battery longevity? Typically with normal usage I am seeing 2 days with about 4.5 hours of screen-on time.
I've experimented with just about everything to push this out including no official facebook apps, decreased resolution, medium power-saving mode, kernel tweaks (currently using TGP rom and kernel), auto-sync turned off. Going beyond this I feel like you may as well just use a push-button device.
Any devs care to comment? What is the main factor that eats the battery on the Note 9? Is the exynos processor just not that power-efficient? Am I missing some hidden gem?
I guess the next step would be to transition to an AOSP based rom where the customisation is not constrained by baked-in samsung features but again, this is giving up a lot including proper s-pen functionality.
I recently kitted out an LG V30+ for my wife and it is just insane to me that a phone which only has a 3300mah battery can get the same life as the Note9 or better.
Is there some strategy I have missed or is this really the best we can hope for? Seems like an extremely inefficient use of 4000mah to me.

This is what you get when you use a high performance chip.
If it was like cars.. just because the gas tank is big (battery) doesn't mean that the engine won't consume the fuel faster than a more Efficient engine (cpu) with less power.
Other phones might be able to last 3 days, but they also dont have the performance capabilities. Turn on extreme power saving and see how long the phone lasts ...
I'm using stock unbranded ROM. I also adp uninstalled all the Facebook system apps (devil-ware). With Pie + OneUI + Night mode + Dark UI apps, it's the first time I love stock. I bet your non-stock ROM + TGP is the culprit.
I charge nightly on a wireless charge pad; easy on the battery. In Device Care, I run the default "Optimized" setting. I use it moderately for the first 12 hours of my working day (meetings phone calls), and I often have 85-90% charge left at that point. I then use the phone HEAVILY for the next 4 hours (watching video, reading, etc.), and at that point I am never below 50% (often 60-70) when I put it back on the charge pad, go to sleep, and start the whole thing over again. I have the US version (Snapdragon), darkmode and auto brightness is always on, and I use Automate to toggle my wifi off when not home and back on when home. Other than that, I have gps, bluetooth, and phone data always on. Bluetooth pairs with my watch and car, and gps auto-toggles by the kernel whenever I load maps or whenever my Life360 app updates my location (every few minutes).
That's all fairly normal use with a bit of power-savings thought into it. If you cannot get similar performance without your screen brightness jacked way up and wifi always on (that eats battery as you move around), then maybe you have a power-hungry app. Check your Device Care section of Settings, and start watching your "Usage by apps".
Also, it's better to slow-charge than fast-charge (wears it out more quickly). And you are better off charging nightly than waiting two days until it's very low.

A lot of people don't realize the huge difference that your cellular connection strength makes a difference on your battery.
Try working in a all brick/stone bank building, where 250kb/s is a good 4g download speed... Then see what your battery looks like after a few hours.

YEP!
And same goes for wifi.....
wifi and cell radios can really eat up battery if they are trying to maintain a connection in areas where wifi/phone signal is weak. And app like Tasker or Automate can toggle these on and off, depending on your location, and really save battery.
Well, that probably explains a few things. I moved in to a SOLID brick building recently with double glazing everywhere and multiple solid brick internal walls. First time I've ever battled for cell and wifi signal...that does explain a lot. I guess 2 days is still pretty good. Might end up with one of those 10,000mah Chinafones eventually ;p
