Problem started from few days ago, my phone started draining battery percentage from 100 % to 1% fast and sticks in 1% for about 2 to 3 hours, if it's software problem how to fix this how to fix this, should I root my phone or what, developers suggest me solution
How battery gets drained mainly depends on how heavy phone's CPU is stressed: a CPU processes softwares' ( Android OS itself included ) intructions send to.

Any ideas on managing the wakelocks on Android and specifically on the Infinity?
I've checked the option of switching off WiFi with screen-off, but in my battery usage stats I still see that over 10% of battery is consumed by Google Services with 672 wake locks & device waked 77 times (WiFi drain itself is 13,5%, so quite OK). This is what GSam Battery Monitor shows. Android stock battery management (in Settings) shows 51% drain by Google Services and 26% by WiFi (but I believe these stats are wrong most of the time or just measure a different thing, as they show tablet inactive with 2% bar and it has been inactive most of the time actually).
I have google auto-sync on and I need it, but I still think this is too high a number. I don't get 672 e-mails daily, so these shouldn't be PUSH notifications etc.
I'm not sure if I'm the only one seeing these high numbers there?
Have you tried CPUspy for finding out how much time in deep sleep you have?
Better Battery Stats is also a needed tool to find more about wakelocks
Sent from my GT-N7000 using xda app-developers app
Yes, I'm looking at it from time to time, but thanks for this. I had some issues when I started this thread, after wipe and re-flashing new firmware it seems OK in the stats: Deep Sleep 44%, 102MHZ 16%, 1500MHz 24% (running on balanced mode, interactive governor).
I'm still curious to get to know how to manage wakelocks under Android from (low) system level however.
almost in all of the custom roms recently, battery drains on standby like 1% in 1hr approximately, currently on engima v3. does anyone has any solution?? can anyone help? may be the reason can be heavy framework of ported roms for premium features.
If 1% per hour this is very good this means it may last for 4 days
Following things can be done..
1. WIFI-ADVANCED-KEEP WIFI on during sleep-disable.
2. Disable data and wifi when not in use.
3. Try super task killer from play store..It helps to really close recently used applications not as from recent panel.
4. Avoid overcharging your phone for longer durations.
May these things help you
iBestWin 10,000mAh (10A) Battery , AccuBattery &the Samsung Galaxy Note 4 n910f - RRm
Hello, Several days ago I purchased (courtesy of Amazon) an extended battery for the N910f & as many have mentioned knowing when to charge the Battery isn't easy for the casual user
(I'm more experienced than the average , have a fairly good knowledge of electrics - I'm mm electrician by trade - & computers / tech etc , but far from an expert compared to many on XDA)
Via the playstore I eventually (tried many) found this app called AccuBattery (Accubattery.zendesk.com) Which allows for the manual implementation of your batteries Basic specs
Here is a link to their manual :
https://accubattery.zendesk.com/hc/en-us/articles/210226065-Tab-1-charging-screen
Encompassing this I have disabled my battery icon & enabled the notification from the app to provide my battery reading & after several calibrations it appears to be reading accurately
I've accumulated serval screenshots for others to analyse ; being a forum all commentary is welcome
I'm easily able to get more than the 18hrs specified using it with my hot spot (for the note 3) , 4G / LTE , bright screen , Nightmare Cpu &Simple OnDemand governers (just straight performance) although I have underclocked the CPU as i have all 4 cores on (This works best for me less processing power but all cores working - very very smooth)
AccuBattery calculates the per app battery usage a bit differently than Android and many other apps (which can only accurately determine the phone's total battery consumption and then uses fixed profiles to estimate the distribution to each app). Instead, we have opted to calculate the phone's realized total battery drain whenever an app is in the foreground and assign all of it to that foreground app.
A benefit of this is that some apps have related background services running that the Android usage screen doesn't capture while we do. However, with our foreground method, we'll also capture background processes from other apps and end up assigning this to your foreground app (For example if you turn on an overlay and then stare at the clock app for an hour then all of that gets assigned to the clock app). We think it's a reasonable assumption though as the majority of the battery drain comes from the screen and many of the unrelated background services run regardless of which app is in the foreground. Furthermore, when the screen is off the background services don't get added up to the foreground app usage as nothing is considered to be in the foreground when the screen is turned off.
The average battery usage section shows you how we calculate our time remaining estimates and is based on the last 7 days of usage.
The fully battery time estimates give you an indication of expected performance on a 100% charge and might be a bit different to some other apps. You can read more about our time remaining estimates here: https://accubattery.zendesk.com/hc/en-us/articles/211277789
This shooting up of android os process battery usage is only after the root.
Google play services and other GAPPS have already been removed from the whitelist of power saving. I have been using my mobile hostpot for about 6 hours and 6 hours standby after it and this is the usage through Better Battery Stats app, from full charge to 39%.
Samsung smart manager shows android OS as the major culprit.
Also total computed power usage doesn't amount to the decrease in battery power. Total power usage is amounting ~ 1000 mAh but battery is of 2600 mAh, this is happening after root and I have fully drained and charged while switched off to full to calibrate the battery, but same.
Earlier real usage time was equal to what is now but estimated usage time was just double when all GAPPS and gms were running in background.
I am posting the screenshots. Can somebody let me know the reason for this and how can I disable the wakelock visible in the Better Battery Stats screenshot?
Does anybody have an idea of reducing Mobile Radio power reported by android OS process?
OneUI built-in Device Care app doesn't show full details of what is draining battery. It fortunately shows the Screen ON Time (SOT) though.
My phone's battery drains badly on standby. It drains anywhere between 1.5% to 2% per hour on standby if I leave all radios ON. If I turn OFF WiFi, Mobile Data, Bluetooth, Location, etc. then the battery drain reduces to 0.5% per hour. There is no unusual drain when I'm using the phone. If I'm continuously using the phone, I can get 6 to 7 hours SOT.
The built-in battery stats doesn't provide full information on what is draining battery, and how much. For example, it doesn't show system functions like Android System, Android OS, Display, Wakelocks, etc. It only shows 3rd party apps installed.
If I add the % consumption of each app shown in the list, it won't even add up to 50% of actual consumption. If you see the attachment, the sum of the individual consumption adds up to about 20% only. My battery is at 59%. So I have no idea about what used the remaining 21% (standby drain).
Assuming that all details are available in the system, is there an app that can simply read this info and show it on screen? I don't want battery 'monitor' apps that run in the background.
I'm interested to know if there is an app that would simply read this information and display it when launched, and won't run in the background when closed.
Thanks.
Gsam battery monitor, better battery stats or Battery guru. But i think that they all need to keep a background service, which doesn't cause any noticeable battery drain though

I seriously doubt this. It is just that they don't show up in the stats.
From my experience, there was no difference in idle drain battery usage with and without any of these apps. Checked for some days, not only a few hours.
