12 Hours Idling and Not a Drop in Percentage!

Better battery life is simply impossible! As the picture below ilustrates, this thing did not sip a single percentage from around 9:00PM to 9:00AM this morning. Sure, the phone was not touched, but even still... I then checked my emails, Twitter, and played some music from my SD card yielding the 9% drop.
I have an Exchange and a Gmail account pushing, Wi-Fi is always on (BT and GPS was off), and Tango, Tikl, SportsTap, SetCPU, Astrid Tasks, and JuicePlotter services running in background in addition to the typical OS services.
SetCPU Profiles:
Temp > 50: 499/245 ondemand
Screen Off: 245/245 ondemand
Charging/Full: 998/245 peformance
Battery < 25%: 499/245 ondemand
Battery < 100%: 998/245 ondemand
Please check my sig for the rest of my setup...

Yea, it doesn't use much power at all when it's not being used.

Well, it normally does... it is still pushing and polling information too/from servers. 1% per hour is already really good, but 0% in almost 12 hours in insane!

not for nothing, but I get the same results with baked snack 1.9, pushing basically the same stuff, but without setcpu.

Those screen shots don't mean anything. Are you saying you only get about 2 hours out of a full charge? Hell, I can watch a movie for 5.5 hours on a full charge.
Something isn't right. If you ARE only getting 2 hours, wipe your phone and start over, something is wrong with your ROM.
I am using Fresh 3.4.0.1, I have 8:50 uptime, 2:55 awake time, and I have 60% battery left. I don't use stepcpu and have not changed the kernel.

The 0% battery drop in 9 hours is certainly impressive but I have a feeling the quick drop after waking the phone up is a delayed indication of the true battery consumption over the past 9 hours.
A few minutes of syncing/email/browsing usually doesn't hit my battery life quite as much. I don't keep great track of my battery life but I know the other day when I didn't have my charger at night I was at 70% after 24 hours WITH mild usage and syncing. Or to put it another way, during my 8 hour workday I lose one/two bars with 4G on, GPS on and autosync. Not too shabby.

Mine did the same thing the other night. Went to bed with 1% left, woke up 10 hours later with 1% left. I was on wifi, however; everything is syncing and turned on, too.

well i just wanted whoever can help to see how low the battery level was and in the screen shots you can see what was running and how long. This isnt the only rom thats had short battery life with me. Something wrong with the phone and or battery maybe? also since your using the same rom/kernel i am do you use or suggest juice plotter and defender?

I stopped using defender or plotter.
Only thing I can think is you are in a poor service area and your phone is constantly searching for signal. That will drain your battery fast.

It's almost 12 hours actually. Also, the drop is due to streaming Pandora while checking emails. That's a normal drop for streaming Pandora and using my BT headphones.

after about a week of lurking and trying to get a grip on owning my first android device. here is my first post
My girl and I got some evo's and me being the nerd that I am with my devices I ended up here within about 10 minutes of having my device.(first eight minutes I was cleaning up the cream in my pants about my new device.) before one trip to reddit.com/r/android (<-beware of the awesomeness that is reddit!)
anyways I digress. I rooted instantly for tethering and started really hating my device because of the battery issues and I continued to read and then i took the plunge.
mine Azreal 2.4 with riptide theme v8 started with Netarchy 4.2 then swithched to kingxclick #11
I am a heavy user and I have been up 12.5 hours with 4.5 screen on time WIFI RADIO only pandora or music or internet vids ALL day. just dropped under 40%
I thought that was good but my girls setup is killing mine
hers Virus Airborne 3.1 with kingxclick#11 and on a full charge and top off method and battery wipe she is running now 27 HOURS with 3.5 screen on time
without a charge and is at 37%
she doesn't use her phone nearly as much as me but her wifi, and 4g on the ENTIRE time.
setcpu setting that worked for me!
kingxclick#11 CFS or BFS: Put the following settings: 1152-256 conservative. Then in advanced settings: Up threshold 95, Down threshold 50, and Freq. step 5. Test these settings out before you click "Set on boot"
(not my own setup just following one if the sages around here's posts)

I get things like that sometimes where it will be constantly decreasing then suddenly stop for several hours. I think it's just an error/inconsistency in reading the battery or something because it isn't a realistic effect.

Seeing similar results with Stock Fresh 3.4 and Setcpu. Look at the time when I went to sleep

Using Battery

I'm tempted this weekend to just leave my phone idle until it actually drops a % and see how long our phones actually have standby time with this kernel.

[Q] Anybody Else Getting Bad Battery Life? (Post your 'Display' usage)

Many reviewers of the xoom are getting 9+ hours of battery life with brightness at least 50% and running music in the background + some video.
I am not getting the 9 hours of battery life, but around 6 hours tops. Is anyone else?
Please post your battery life 'display usage' time. I feel like I have a bad xoom.
Again, if people can post their 'display' usage time, that'd be great. Meaning, the time the display was actually on one charge.
IF you cannot take screenshot, please type in your 'display' usage time as shown in the screenshot below.
TO FIND OUT DISPLAY USAGE TIME: go to SETTINGS -> ABOUT TABLET -> BATTERY USE -> TAP 'DISPLAY' -> SHOULD SHOW ACTUAL DISPLAY TIME ON. meaning, it shows how long your display has been on since being off the charger.
The screenshot shown below is with wifi on, bluetooth off, gps on, brightness settings at ~40%, starting from 100% battery life)

nice screenshot..

nobody experiencing bad battery life? pretty close to returning the xoom..

Sorry, cant show a pic due to not having my XOOM on me. But im getting ruffly about 6-7hrs with decent use. But that's what I expected. The "approx" numbers they give you on mobile devices are always over shot in my opinion.

The worst battery life I've gotten so far, when using it constantly for a given period of time (Web browsing, some Flash video, email, Twitter, some gaming) is around 8%/hour drain. That would equate to around 12 hours total, which I can't verify because I haven't used it for nearly that many hours straight.
I supposed if I played games solid hours on end I might burn the battery in 6 hours or so. Conversely, in my typical use, which is on and off browsing, email, Twitter, newsgroups, Pulse, CNN, light gaming, some video, I take the Xoom off charge at around 7:30am and by midnight when I plug it in again I have about 50% remaining.

wow, there is no way i'm getting that good of a battery life. i think i have to return my xoom and get a replacement...
so you're saying from 7:30 AM - midnight you're getting 17 hours of display time? that doesn't seem right..

I get 15 hours easy with moderate use and around 11 heavy heavy use.

i mean DISPLAY TIME USAGE
go to data usage -> CLICK ON 'DISPLAY' -> SHOULD SHOW ACTUAL DISPLAY TIME ON. meaning, it shows how long your display has been on since being off the charger.
if you can take screenshot of your actual DISPLAY USAGE that'd be great. the screenshot you have is NOT the same...

Sure didn't, I'll post my results tomorrow. Its currently at 97% with over 3 hrs of display usage. If your Xoom is only getting 5 I'd say your Xoom is defectve or something else other than the screen is draining your battery.

I get great battery life, 65% remains

Maybe a better pic

I have good battery life when using the tablet continuously, but AWFUL battery life if its asleep.
I dont understand it - my drain while screen off / asleep is about 5% per 2 hours or even 5% per 1.5 hours...
and it usually shows android OS as taking up the usage while asleep.....
im at a loss of what to do.
I actually used it continuously for 9.7 hours of reading/wifi on time - so my battery seems fine.. but something is draining it while asleep...
I even tried to do a factory reset and wipe all my programs... and it still does it...
i dont know what to try now..
when i shut the tablet off - the battery does not drain - so it must be in the OS or something.
Any thoughts?

once again, i'm talking about actual 'display' usage
SETTINGS -> ABOUT TABLET -> BATTERY USE -> TAP 'DISPLAY'
as of yet, nobody has shown me their 'display usage' as of yet...

Display time on: 7h 23m 41s, and my battery is currently at 31%. I haven't charged it since Saturday. My guess is you have a lemon.
P.S. Sorry for the bad quality of the picture, I don't have my USB cable with me.

screen on time 7 hrs 02 minutes with 30% battery remaining

What else is using the battery? Just the display usage alone is useless. The display is only using 62 percent of the battery. Which is really not a high percentage. It looks like something else is using up a lot of juice in a shorter period of time.

The only time I got less than spectacular battery life was when the "minimalistic text" widget ran way with 6% of my battery. Since uninstalling that app, I have had no issues.
Is your brightness jacked up? I use it on auto.

Battery DRAMATICALLY Affected by Brightness

**PLEASE READ THE TITLE**
This is not a general battery life thread. I'm looking for comparisons of brightness levels. Thanks.
ALSO: Has anyone noticed a difference when using black themes/wallpaper, etc. I have NOT noticed any significant difference.
Ok, first off, everybody knows brightness affects battery use. However, I've been trying to run my brightness at 30%, which seems pretty low. I figured that can't use much more power than 0%. Still, I've only been getting to about 2pm after charging my phone all night. I'm a heavy user, I like to tinker with my launcher a lot, check facebook, texting, etc.
Today I decided to try 0% on the brightness setting. I'm not crazy about this since it's not bright enough for most situations. I mean, I bought a SAMOLED+ phone for a reason. Anyway, the battery usage seems to be DRAMATICALLY less than with 30%. What's even more odd is my battery usage shows my display using 40% of the battery instead of 50%, which is what I normally see. This isn't a very significant change.
So what about everybody else? Are you guys having the same experience?
UPDATE: I'm up to 7 hrs now and have 67% battery left. Screen on time 1h 26m. This is a dramatic improvement still from 30% brightness.

Ive had my brightness at 100% for most of the day. Im getting great battery life. Im a heavy user and I can get atleast a 1 1/2 days with a single charge. Luckily I hve the luxury to charge over night.

You sir are not a heavy user if you can get 1.5 days with a single charge on 100% bright.
Or maybe a heavy user on calls not browsing or things that use the screen.
on 100% simply 1h browsing, 1h with video, 1 account sync, texting, some calls, check twitter and fb will kill your battery in less than a day, and that is not heavy using.

Can i ask how many hours you have your screen on,
because with 100% brightness i'm lucky to get 3.5 hours (internet/games/twitter) of use out of my phone.

copy and paste from another thread I posted in. This is a very typical day. Now I dont use my phone as much after 6. My phone is currently at 30% from a full charge from friday night.
I make it during the day with 100% brightness. I consider myself an a heavy user.
Ill show my usual day after the new factor wore off.
Unplug at 630-7am
Start my music through Poweramp around 9am at work.(20 gigs of music)
about 20 text/ 30min total of calls
20 or so emails with some attachments
Usually download about 200mb of music/videos throuhout day
Check about 10-15 websites every couple hours(xda app most frequently)
Use Logmein about 10-15min total
Play LIVE holdem Poker roughly 30min total
Youtube/video watching
Some other random things I cant remember
3g/h+ on all day
wifi stays on
brightness at 100%(bright orange/blue wallpaper)
Browser brightness is at 50%
Everyones experience will be different. My original Samsung galaxy s(vibrant) would be dead around 5-6pm. My Galaxy s2 is around 40-50% around 5-6pm. Im experienceing great battery life. My fiance iphone4 would kill my vibrant in battery life, but the sgs2 is on par.

Yes, I too find this very hard to believe. I know if I watch a high quality video on YouTube the battery drain is insane. Of course that is data also but I doubt I could get an hour. My guess is if I just left the screen on for 2-3 hrs my battery would be dead from 100%.

Nope, that's definitely impossible.

I don't believe you, period.
On my s2 I lose 30-40% in 2 hours of not very heavy use on auto brightness. I am shocked that when I surf I can see the battery number (using battery guage) actually ticking down. Device is nice but battery life for me makes it totally useless for a prime device.

I've got display at auto-brightness which is usually around 30% for me indoors. Got display on time of 4hours 16minutes..includes about 45minutes of 3d gaming (modern combat 2) and rest browsing/downloading etc..
total up time 12hours 39minutes...and got 22% left...thats incredible to me, coming from a desire hd, I cant believe my phone is actually still running haha..
EDIT: Oh yea forgot to mention, I got a new replacement yesterday which means I havent even gone through the charging cycles yet, my previous one was superb aswell so fingers crossed this one will be too

Im off today so my typical use is different. Ill repost my battery stats when I get home after work tomorrow.

Well this is helpful, thanks. Sounds like you are getting better battery life than me. Although I would say I definitely am a "heavier" user than you. I used to make it to about 3pm with my GS1. I'm getting about the same with my GS2 if I leave the brightness on auto. That's if I don't use YouTube for more than a few min. I too would like to know what your screen on time is at the end of the day.

Sorry, posted this in the wrong place

That use and that battery it is simply a lie.

The screen is definitely a battery drainer. Don't set the screen to 100% brightness and record 1080p videos. Battery level will be at 0% in less than 2 hours.

Why the f would I lie? Samsung is not paying my bills nor cutting me a check. ill post tomorrow after work my battery stats.

That is impossible on THIS phone with THIS battery! Period!

I'm waiting for those stats.

A screen shot of his display on time along with the graph is what's needed.

Can we get back on OP's original topic of display brightness vs battery life discussion, this is a topic I'm interested in as well as I leave mine on auto-brightness and display is always #1 on my battery consumption list.
Maybe intruda can start a thread called "How my battery life is superior to everyone else's SGS2" and the dissenters can go there and call him out. Just sayin'.

This is my usage today with auto brightness. Mostly at 30%-40% brightness with 45minute gaming and rest browsing. Music. Youtube.
Im impressed.

44 Hours of battery life!!!!

I'm running Toxic Crazy8, stock battery, Bali Kernel, undervolted an extra -25v across the board, reduced clock speed to 400mhz when screen's off. Light use gave me 44 hours of battery!
I probably could have pushed it even further. The first night it was updating 35 apps over wifi, and that sucked up almost 60%

Got even better battery life? Post a screenshot =)

That's great an all but it comes slow. Try multitasking or play a simple game. It will lag like crazy. 44 hours is too much anyway, for me 12 hours would be the best.

I got 48hrs from the same rom, with wifi on constantly with skype. light to moderate use. Music at least 2+ hours twice in that span as well. Great rom. I chose not to UV or overclock so I have no SetCPU or anything installed, it's stock toxic with the 98 kickass script and v6. Really fast actually and no need for oc.

thats impossible with "moderate" use.
its light, and i mean like.. VERY light not even to the scale of being the actual light... so techinically your not using light, but using little light to no light at all.
P.S. my sentence includes 6 words "light"
now that i'm done with that bull****.
Please people posting their batteries as 40+ hours, PLEASE start using your phone. or just get a feature phone, honestly.
I, too, keep my phone on standby more than actual use, but i DO use it when i can. theres atleast 8 hours of music daily, constant wifi use, 24/7, and i get near 20 hours of battery life because i consider my use minimal moderate. At the end of the day, my battery life is usually at 40%, then i charge it again.
I'm on MIUI as well so battery life isn't perfect and i can deal with that.

I SAID "light to moderate"... Also how can one judge what moderate is vs moderate with a guy who acts like a girl being on the phone all day texting and talking??? It's a ridiculous to even judge moderate or light vs someone else, because everyones concept of light to moderate are vastly different. So don't come at me like that bro.
Light to moderate (hence i didn't use strictly moderate) to me is at least 1 and a half hours on skype calls, at least an hour and a half on calls, a few texts on skype and sms, 10+ emails, a few show-offs lol, Wifi never turned off and skype always signed in, at least 4+ hours with music at the gym and a little after, a few random checks, a few market and web browses and maybe a short vid chat. That's light to moderate to me.
If you want to see less than light, like when I'm sleeping and checking my phone occasionally with wifi set to never turn off and skype signed in always I'll show you. It's been almost 12 hours since i was at full charge and unpluged and I am now at 94%. seems ridiculous I know and I thought so too but I ain't complaining. Stock battery as well. I'm no way saying this is light or what have you because it was idle for 90%+ Just an example of how deadly toxic 8 is with battery. And I do have apps. I dont usually play games though.

look at the attachment.That was after I downloaded 2 apps and tried them both lol and couldnt figure out how to screenshot. I'm done with this "bull****" now.

Once I see the cell standby is higher than the display I pretty much know how you use your phone.

No, you only know what you see. I am running Toxic8 also and am getting around 30+hours of real actual use, granted 8 of those are when I am sleeping, but still get strong use all day long.
Day in my battery.
Get up and go to work at 7am, listen to Iheartradio until 930-10
PowerAmp until 130 lunch with texts and email checks throughout.
130-2 XDA, random surfing
2-6 I listen to 2 different podcasts.
6-7 ride home on bus and listen to PowerAmp and check XDA again.
9-10 after kids in bed and I play a few games and check/clean some files in
Root Explorer.
Go to bed and then start over in the morning and finally plug in around 10 or 11 (lunchtime)
The cycle may shift a few hours here or there but it almost always the same. Oh and not sure if it is this ROM or not,but if I go into settings>about phone>status>batteryuse the picture shows that my display is at 75%, stand-by is 15% and phone idle is at 10% all +/- and that is clearly not the case. So you think that you see what my use is like but really you aren't.
I also use Juice Defender Plus which kills the radio/data traffic for an app-to-app basis and I have it set to kill radio/data while I am asleep.
I can post a screen shot if you like of the battery use (seeing isn't believing) or a shot of BetterBattery Stats (seeing is believing) if you like, but I am using my phone all day AND getting 30.

my vibrant hates toxic 8 for some reason. ultimate rom on the other hand has been very fast, responsive, and long lasting.

I prefer to actually use my phone for what I paid for it to do.....if I just want a phone ill go buy one out of a gumball machine or pick it out of a box of cracker jacks

I was at 19 hours and 31 minutes using the Stock ROM with 41% battery left.
That's 33 hours if I had let it go all the way down with the same usage, and I definitely used it more than the OP does if that screen shot is any indication.
Didn't use airplane mode or anything.
I just uninstalled all apps I don't use and use a Black Background with only 3 home screens and a 30 second screen time-out.
WiFi used whenever I could, and I keep GPS on all the time now. Automatic screen brightness, too

The people who are being negative, what do YOU consider good use? I'm on trigger 3.2 final with bali 1.8.8 kernel, and my phone can get 24 hours with occasional use and still be at 50% battery, easily 24 hours with REAL use.
Real use includes calling for 1-2 hours, playing at least an hour of games, and just syncing off for apps I don't use constantly.. I don't have the phone underclocked when screen is off or undervolted any more than the kernel is set for.
How do I get that battery life? When the screen is off, it is in deep sleep. I get less than 1% battery drop per hour when it is in deep sleep. So basically unless I'm ACTUALLY using my phone, it isn't draining.
The part that impresses me is that I get easily 20+ hours of heavy use on the ORIGINAL battery(over a year and a half old). I know that battery must have lost some of its ability to charge.. I got my phone replaced by warranty, and the battery they included WILL NOT give as much battery life.. it makes me think that the problem with some people is a combination of a crap stock battery, and wake lock issues..

Wow this is some crazy stuff! I've been on GB for a long time now. I was just thinking the other day to flash back to 2.2 just for the lulz. But then along came the ICS port.
It seems I should try this out.
Sent from my lazy couch

THIS is what really light use looks like.. maybe an hour of calling, a few dozen texts, reading some news..

2.2 toxic is a great rom. i think it doesn't get enough love because of the GB and ICS options.
either way even 12hrs of battery life is pretty nice congrats

What I don't understand is:
1. How come it's on flight mode?
2. How come Display < Stand By?

Running on stock 2.2 with 3G, WiFi, Bluetooth, and GPS turned off, barely any apps installed so nothing started up in the background, and not recieving any calls all day my battery went from 100% to 93% in 13.5 hours. I estimate just shy of 60 hours of potential battery life.
But that was with a phone that wasn't being used at all; i.e. a paperweight. I could just turn the phone off and claim I had a bajillion hours of battery life.
FYI when I took the sim card out of my daughter's iPhone 3G, turned off wifi, and shut the screen off it lost about 1% PER DAY. That works out to a 3-month battery life (give or take) but again it's just a paper weight at that point.
In other words, if you're using your phone as an MP3 player for 2 hours a day, why shouldn't it get 44 hours of battery life?

Ok so i read all this hype about crazy8 so im trying it out now...
Damnit im very impressed....
I watched 2 movies complete played angry birds, on my phone for most the night and this morning when i got off work 9 1/2 hrs later i still had 35% battery life.
That is awsome to me,though i did not get 44 hrs due to i actually use my phone i will say im impressed,,,,i now no longer need to carry my 3 batteries and the external charger with me everywhere i go lol
I normaly go thru 2 battery changes a night.
Tonight i will run with all the script tweeks and so on...im excited to see the results then lol...although i will not run plane mode and undervolt it and all those lame tricks, actually may oc clock it a bit.
No more miui and cm7 for me lol bad ass battery life with everything working and snappy as hell....im at home with crazy 8

Battery life discussion

Let's get the ball rolling on this one! Post your battery usage and screen on time

1 day, with 3.12 minutes of screen on time with 4% remaining. Sorry I don't have any screenshot to show.

I got close to 5 hrs. SOT on the first charge. Used the phone a lot that day all on 4G. 1 hour of phone calls over Bluetooth, 45 minutes navigation, updating and downloading apps and a lot of web surfing.

Dismal Battery life
So, I'm averaging between 2 to 2.5 hours of SOT.
This is with WiFi on, BT off, location used periodically (like while booking an Uber), NFC off.
I have been using this phone for 3-4 days now and thought the battery life would improve but this is dismal.
Can anyone share some tips?
My brightness levels are at 50% and not on auto.
I'm new here so I can't post pictures/links

I get more than that from my xa with a 2300mah battery and no stamina mode, I'm getting anywhere between 3.5-5hrs screen time depending on where I am and what I'm doing at the time brightness at 40%.
Have you turned off the WiFi and Bluetooth always scanning in the background even if they are both turned off go to settings, location and tap the three dots top right, then turn both sliders to the off position. Made a world of difference my xa battery life.

Was on wifi the whole day

I've been using the phone about a week now. I am very satisfied with my battery life so far. Last night I flashed the UK firmware to access the Battery Care feature as well as the fingerprint sensor. We will see if my battery life changes post firmware flash, but it seemed to do fine today. I unplugged it at 7am this morning and its now 10pm and I am still at 50% battery. Every day I have been able to comfortably reach the end of the day with 1/3 or more battery life, typically over 40%. When I am not using my phone heavily I turn stamina mode on, then if I want to sit down and use it I'll just switch it off. The battery life is much nicer than my Galaxy S5, Xperia Z5, and I find it to be somewhat better than my Galaxy S7 as well.
Well apparently I won't be able to post my screen shots until I post 8 more times. So I'll just write out the stats I have.
Using GSAM battery monitor pro
Averages per complete charge:
Battery Life: 22 Hours 20m (7 hours 49min active)
Screen on: 4 Hours 31 minutes (max 4 hours 48 min )
and upon the time of posting this I was at 50% battery. The phone has been powered on for 14 hours and 18 minutes.
Phone active for 20 minutes
screen active for 3 hours
cell and wifi on all 14 hours
held awake for 1 hour and a half
Edit: I should also mention I run the Nova Prime launcher

I average between 3.5 hours and 5.5 hours SoT while there's 50% battery remaining.
It's mostly calls, calls forwarded feom my business phone, MyBoy, a lot of chrome usage and a bit of other stuff.
The best battery life in a Sony flagship phone.
Beats my previous Z1C, Z3C and Z5C, and it utterly destroys the LG G4.

wow! Everyone seems to be getting at least 3.5+ hours of SOT. wonder if I should give those guys at Sony a call and check with them!

Anyone experiencing huge battery drain from Android OS?

So I had this phone for 3 days now. 1st day was setting it all up which of course drained the battery faster than usual. 2nd day I wasn't getting any signal and realized I needed to set up the APN settings for T-Mobile so I couldn't really test the out the battery life under my normal usage. Today, I went from full to 75% in a matter of an hour and a half. This is not normal. My normal routine is starting up streaming music services such as Stitcher, Spotify, and a couple others and maybe 10 mins of browsing during my 35 min commute on the subway train. At times I get spotty coverage during the commute so I understand the phone is working harder than normal to get signal. But that 25% drain should not be normal. I was getting at most a 11% drain with my z3 and 15% drain with my note 7 under similar circumstances. I will give it a full week or two and hopefully things will settle down a bit. If not, this is a huge concern and I may have to return it.

Give it a couple cycles and play around with the stamina mode settings. Lithium batteries generally won't output their full capacity until 5-10 charge and discharge cycles. That being said your battery life does sound somewhat short depending on what you have running in the background. I Use the memory booster application to monitor my RAM and clean it every so often which saves some battery life as well. But I would give it a couple cycles and see if you still experience a shorter than expected life

Screenshots taken at 15% remaining because that's when I have stamina mode set to kick in.

Today's usage was a fair bit of Google maps (screen on for about 3hours.) Using around ~75% of battery.
Plenty of YouTube via chromecast (screen on for 1hour)
For whatever reason battery stats are not showing me YouTube usage. When going into app Info you see 0% which is a lie. Because beyond he 1hour chromecast session I then used it for another 15minutes via the phone itself. So that stat is wrong because it certainly consumed battery.
100% unplugged at 5am. Screen off until I officially woke up at 8am. Still 100%. Proving the phone sleeps brilliantly.
Then the video attached taken at 1% illustrates the usage detailed above - giving a total ~12.5hours with quite intense usage.

My record SOT STAMINA automatically 25%

Well to be fair MyBoy is one of the most efficient apps you can run on a phone. My GS7 could hit 7h of screen on time on that, double what it can usually achieve doing just about anything else.

Not really happy with the xz battery... Being a 1080p display and sd820...i expected it to do lot better

This battery is weird. Most days I get around 5 Hours of SoT around 20% battery life left but yesterday I was at 50% battery life at 5h30m of SoT. Unfortunately I didnt screenshot it but it was draining super slowly I have no idea why, my usage didnt change, still used the same apps. It happens every once in a while.
Also does anyone else have severe drain with Android System? It shouldnt be surpassing my Display drain at 50% brightness. I would show screenshot but Im a new user.

Battery so far is great for me. This was with 15proc left, so could easily reach 7hours.

Wow most of you have really good battery life and SoT! I'm getting around 3-3.5 hr max sot over a 12-14 hr period... Anything I should be doing besides uninstalling some social apps (which I use but could exchange with web apps)
