The maximum i can get 1% to last in standby mode is 23H47M i was busy and left my tablet unused for over 24Hrs
The T705+ and T805+ have cell lte transceiver so they will not get as good battery life as the wifi only Tab S.
I have use Titanium Backup to freeze 6 unused apps, and used Sony Power Nap to keep my T800 from waking up due to waklocks so it spends as much time in deep sleep which use the least power.
Free Kapex Battery Monitor, to monitor how long your battery stays in every 1% of battery capacity.

Free, Needs Root, CPU Spy Reloaded, to view wakelocks, it is easier to use than Wakelock Detector and look better.

Using Battery Monitor WIdget, my OnePlus One phone on CM12 has an average Deep Sleep standby current of around 8 mA.
Using BMW on SM-T800 stock 5.0.2, my Deep Sleep standby current was around 85 mA ... 10 times as much!!!
That's insane.
I disabled/uninstalled a bunch of the Samsung bloatware apps, and things are a little bit better: Averaging around 45 mA now.
But, that still seems insane. Shouldn't Deep Sleep get me lower than 45 mA?
Unfortunately, I can't get Wakelock Detector working on the SM-T800.
What is your average Deep Sleep standby current? And, are you running Stock 5.0.2 or something else?
Isn't anybody interested in improving their battery life? I know I am.
Just installed it, I suppose you leave the tablet for an hour then check the log file to see how many ma were being used when the tablet was supposedly in deep sleep mode.
I use GSam Battery Monitor for the Alarms, I am looking for an wake-lock app that works without root, I am always lloking for ways to save battery power.

Hi, @Tinderbox (UK) - I usually leave my tablet or phone idle overnight, so you can see a good pattern. With BMW, you can display the battery draw in mA, and set up the history tab to see the mA draw per reading.
Showing the % battery drain per hour is useless - If you have a big battery, the numbers could look small, but your current drain may still be higher than you want.
Hi there guys, I've noticed over the last week or so that I've had my phone that the biggest battery drain by far is the phone idle (12% vs 3% screen). is there a way to lower idle power consumption?
Install GSam Battery Monitor (or similar), run it for a day or 2, look which processes uses most power, specially keep an eye out for unnormal Wakelocks (needs ROOT'ed phone).
My phone idles at about 0.1% per hour (ROM 20150907)

Same issue her. Battery statistics says Google Backup transport, which points to the lillipop battery drain bug..

I haven't been able to root my last few phones so I wasn't able to really use Greenify recently (i mean I know I could use it in non-root mode, but I never cared for that and found that to be kind of buggy)...
With all the battery improvements supposedly implemented as Android has continued to evolve, do you think that Greenify still offers any benefits?
My standby drain is not so good -
According to EXKM My idle drain is somewhere around 3-4%/hour.
According to BBS, so far today out of 5 hours 30 min on battery, I have drained 5.2%/hour, down 28% in total, with almost 3 hours of deep sleep (54%), 1 hour 23 min of screen on (25%), and 1 hour 5 min awake (w Screen off) (20%). The 1 hour 5 min awake seems high to me - I did listen to 15 minutes of music so that would explain 15 minutes of it.
I checked out my partial wakelocks and the highest is ImsSenderRxr.
According to Battery Usage in settings #1 is Screen at 1 hour 23 minutes (that's good it is first), #2 is Google Play Services which has used about half the same amount of battery as the screen, #3 is Ambient Display which has used almost as much as play services.
I'm going to try adding Greenify and see if that does anything beneficial, but figured I would ask the community to see what your mileage has been like with Greenify more recently since it has been awhile since I've used it.
Honestly, I haven't found much of a need for Greenify, aggressive doze, or wakelock blocking apps on 8.0 and above. It might be beneficial to Greenify battery hungry social media apps (especially those related to Facebook), but then you end up with Greenify running constantly in the background. Plus it requests usage permissions, enabling it as a device admin, etc.
Do you have Adaptive Battery enabled? There is a thread in the general section where a few users have reported that their battery life improved after disabling it.
I came here wondering the same. I had Greenify installed for a while but im not sure its really doing much anymore. I just took the lastest OTA update and im gonna roll without Greenify to see if there's a difference. Ill report back in a few days.
I know it's the wrong phone. But I have just bought a Pixel 3a and am introducing myself to its battery usage. I use Greenify on my Galaxy S7 running superman rom. I forgot to reinstall it last time I reinstalled things and I reckon it makes between 20% and 30% improvement.

My idle drain using EX is usually around 2%. What is your charging behavior... overnight and leave with 100% in the morning? I leave mine on the Pixel stand all night. If you are keeping it in your bedroom off-charger, use flip-to-shhh. You should have done that with BBS. If you didn't run BBS again overnight. 100% charged, hot off the charger and flip it upside down. This is just for a proper overnight battery drain test. Second, I would install Accubattery. It is NOT a battery drain app, but rather will eventually zero in on your remaining battery capacity compared with new. It uses several full charging sessions from say above 20% all the way to 100%. After a few full charging sessions it will give you solid information the condition of your battery. Just ruling the battery out here. If Accubattery confirms your battery capacity is well over 90% then you may want to do a fresh install. Sometimes that is the only thing that is going to return the good idle battery drain. Just my .02 cents. Take it for what it's worth. For reference, my battery capacity started at 106% new and is now at 94%. Cheers!
While web browsing, at 120hz, i loose about 1% every 5 minutes, this totals at about 7 hours screen on time.
Idle times seems to be about 1% an hour, is this normal?
Here are my average stats for the last 7 days. I charge my phone over night, so these are "idle" stats during the day (phone in the pocket, active whastapp web etc.). 120Hz active + automatic brightness.
Your idle usage sounds ok, screen on is a bit too much.
Its hard to compare the screen on time stats since i use GSam, which display stats a bit deferent (percentage per discharge not per hour), i believe you use AccuBattery?? will continue collecting data while i wait for my bootloader to unlock, will switch to EU, see if that helps.
Yes, I always use apps which measure screen on/off discharge per hour and separately, in this case it's AccuBattery. That's probably the only reliable way how to compare battery consumption between phones or between ROMs/kernels etc. Also it allows to quickly see if there is some issue or rouge app which prevents deep sleep for example.
Since the update to FVC7 my battery drains much faster than usual. During the 6-7 night hours it loose abt 10% and after around 8-9 hours of moderate use the battery rich around 20-25%. Better battery stats does not show any thing unusual.
any help will be appreciated.
I only noticed that Screen On time drains battery like crazy just having Display set to 1080p (Medium) and refresh rate on 60Hz (low).
For me it's "only" the display that drains battery very hard. Screen off time is pretty good, but I have a lot of Apps in Standby and Deep Standby.
But BBS was never adapted to Android 12 and Samsungs on Battery service is missing a lot. Look into RAM optimization which Apps are popping up that shouldn't do. Even if it's very low on RAM, if it's an App that hadn't been used since last boot and doesn't need to work in background, than it should go directly to Standby or Deep Standby.
I might be off, but as I'm looking at it: With (Deep) Standby option, Android 12 finally adopted Greenify a long missing feature on every Anroid OS.
