Improve battery life of wear os specially oppo watch - Wear OS Software and Hacking General

So friends i recently bought OPPO watch 41mm everything is amazing about this product except its battery life without power saving mode. While using Bluetooth connectivity only i am Getting 6 to 8 hr of battery backup and need a to charge it 2,3 times daily with average usage.
at flip cart site most of users are complaining about the same so i researched some points and applied to watch and i. Getting satisfactory whole one day battery life on this watch while doing day to day activities like calling, messeging and health activities.
So you need to follow simple steps as below
1)Update wear os to latest one:
Sonwatch comes with 2.18 when we unbox it so immediately after unboxing watch batyery life gets discharges very quickly you have to fully charge it an dthen go to setting> about>system update and update it to latest 2.19 wear os version.
2)Disable all transition animations :
To do this you need to enable developers option go to settings >about >click 8 times on build number
Now go to developers option and disable all transition animations.
3)Disable all gestures :
So to do this go to settings >Personalization >disable tilt to wake, touch to wake and wrist wake
So tha main question arises how to use watch to hekc time and day to day activities for that you need to enable AOD(ALWAYS ON DISPLAY) and to wake the screen use power button. So AOD drains battery for that we need to enable Low bit ambient mode to enable this go to settings >developers option and then go to wear os developer option and enable low bit ambient mode
4)Disable ok google detection
5) always keep wifi, nfc, gps connectivity off use them at emergency only
6) Use pixel minimal watch face:
This is minimal watch face which shows main informative text in white color and with balck baground which save battery life on amoled screen

[info][tips&tricks] lg g2

Hey All Getting new G2 on 7/7/14 and I'm excited
Found a website for some tips and tricks and i really like it for people who are new to the device
http://au.ibtimes.com/articles/515749/20131022/lg-g2-top-30-tips-tricks-fully.htm#.U7oK3ZEgOao
Shout outs to the Website Poster Ryan Inoyori
LG G2 is an innovative smartphone which understand gestures rather than reliance over hard buttons. It is packed with Qualcomm Snapdragon 800 CPU, 2GB RAM and 3,000 mAh battery pack to suit your needs. If you want to make it more powerful and get the hidden secrets, know the top 20 tips and tricks for performance optimisation and extended battery life.
Features and System Hidden Tricks
1. Smart Screen
It is quite similar to the Smart Stay feature of Samsung Galaxy S4 which detects your eyes if you're looking at the screen and dims or lights up accordingly.
2. KnockOn
KnockOn allows you to wake up the display without pushing the power key. Simply knock twice to light up the screen. Use the same gesture to turn off the screen display.
3. Instant Desktop
Pinch out to hide all applications and reveal the home screen instantly. This feature will not let alternative launchers to access unless otherwise said.
4. Quick Camera
For three seconds, hold the volume down when the screen is off, to quickly access the camera app and snap a picture. This acts as a camera button whenever you are facing the rear-camera.
5. Quick Note
For a quick launch of Note app, hold the volume up for three seconds when the screen off to quickly make notes.
6. SMS Themes
Messaging app on G2 feature themes and changing is as easy as going to Menu > Settings > Conversation theme. You can customise the theme yourself and set different wallpapers per contact.
7. Screenshots
Normally, you need to use the volume and power keys to get a screenshot but in G2, you can swipe the button of the screen then slide right to access quick memo. Use it to take a screenshot and share it if you want.
8. Wireless Storage System
Transfer files wirelessly through wireless network connection using IP and password. Once connected to a wireless network, enable it using the notification drop down and follow the instructions provided to you. Using the optional static IP address is also possible.
9. Images with Full Frame
Use the W10M option or wide 10-megapixel for viewing images on your G2. Using the 13MP has an aspect of 4:3 ratio which creates black bars on images.
10. Clipboard Manager
All copied images or texts are stored in a built-in clipboard and you can access it by press and holding on an empty text box. A clip tray will take directly to the clipboard.
11. Gallery Functions
Inside the gallery app, pinch the image to show the option mode where you delete the file by sliding up or share it by sliding down.
12. Guest Mode
You can now personalise a guest mode on LG G2 and it can control apps and capabilities available depending on which mode is enabled. Go to Settings > Lock Screen settings > Set a separate pattern for Guest Mode > Set apps accessible in Guest Mode.
13. Plug and Pop
Set the animation appearing on the home screen whenever you plug in an ear jack or OTG cable. Go Settings > General > Accessory > USB Storage or Earphone > Edit app panel > Set preferred apps.
14. Audio Zoom
Zoom in on a specific audio source during video recording by zooming on your subject. Audio Zoom uses three stereo microphones to amplify the sound from that specified source.
15. Text Link Transfer
You can transfer information from a text into another application. Simply press and hold on the text and a pop-up menu will prompt to which app you want to be transferred such as map, browser and calendar.
16. Dual Camera Functionality
Like the Galaxy S4, LG G2 can use both of its camera at the same time to capture images and even record videos. In addition, the feature uses picture-inpicture technology to put your face in any photo or video you are recording.
17. Tracking Zoom
Use this feature to zoom in on moving subject you select and track actions in a separate pane overlapping the background video.
18. Zoom to Track
If you want to view the subject on a closer range within a video, select the moving object on the playback and choose Zoom to Track to zoom in to track the subject throughout the clip.
19. Capture Plus
Use the Capture Plus to get a screenshot of the entire Web page with precise border controls.
20. Clip Tray
The Clip Tray or commonly known as Clipboard in PC which stores memory of pictures, text and links for future reference use. In addition of sharing it to other apps, it also allows you to store multiple items, create visual collection of information and add items selectively.
Battery and Memory Optimisation
1. Home Screen Panels
Use as many as needed home screen to avoid slowing down the LG G2. It is recommended to utilise the default home launcher for best performance.
2. Widgets
All widgets in the home screen and lock screen consume battery and memory which you should monitor regularly. Use widgets which you truly need and enable auto-syncing if necessary.
3. Live Wallpaper
No matter how fast and fluid the G2, make sure to use Live Wallpaper which are stable and eats less power. Live Wallpapers combined with several widgets can slow down the device eventually.
4. Brightness Level
Manage the brightness level to juice more out of the battery and minimise it before you go to bed for battery saving purposes.
5. Screen Time-Out
If you prefer the device to turn off its screen automatically, set the screen time-out to a minimum such as 30 seconds or 1 minute max to save power.
6. Removing Applications
Uninstall apps which you do not use anymore to clean the clutter to the RAM and battery. Some apps may contradict functions to one another, so be careful on downloading from the Play Store or any other sources.
7. Wireless Connection
Disable wireless connectivity such as Wi-Fi, Bluetooth, GPS and mobile data when not in use to prevent them from draining power.
8. Software Updates
Don't forget to check in regularly to the LG G2 Web site, on your software updates found in the settings and the default PC suite of the device for new firmware releases. New updates include stability improvements and battery enhancements.
9. Regular Reboot
Reboot your smartphone regularly after every full charge so that the memory and apps will get refreshed after an entire day of usage.
10. Backup and Factory Reset
Always create a backup of all personal files and information stored on your device to ensure protection if something happens. Performing factory reset may be needed if an error or technical issue occurs. Backup first before performing any reset.
Good point, but i think you should format it a bit, maybe with bold fonts and underline etc. for better reading, maybe something like this:

The battery optimization options are kinda useless.
I've yet to see a live wallpaper that will slow down a Snapdragon 800 with 2 gigs of RAM. Plus, not all live wallpapers drain the battery (maybe it was so in the olden days of Gingerbread, but today stuff like Muzei are pretty light on the battery). Disabling wireless connections also makes no sense to me, especially in today's world where everyone and everything is connected. Also, the GPS module does not use battery when it's on, only when an app needs location access.
The biggest battery munchers are:
- high accuracy location access, coupled with Google location history
- CPU intensive apps (games, mostly)
- too short sync intervals (like every 10 minutes)
- rogue apps running in the background that won't let the phone go into deep sleep (I'm watching you, Facebook, I know what you're doing).
Great information,.very use full for G2 noobs
I am always confused with screenshot process.
Could anyone here do a little more detailed guide.

This is kind of a misunderstanding.
The sensor in the G2 is indeed 4:3, so full size (13MP) images indeed have black bars on the sides when viewed on the phone - but nothing is added to the images. The black bars are simply blank screen space.
Also, using the W10M mode effectively crops a bit from the top and bottom of the image. If someone is only viewing the photos on the phone, than indeed W10M might be better, but if you plan on downloading them to your PC, it's better to shoot in full resolution and then crop as needed.
Thank you!
Thanks for the tips and tricks.

Battery consumption via running different tests

Hi guys!
I would like to start a small project. The whole point is to find out in which circumstances battery is running down faster/slower. It's more less about consumption and I hope we all will benefit from that simply by knowing what to avoid and if some features of Gear S are really draining battery or if it's just a myth.
I'm really looking forward to update this project in time.
Because of the nature of this project. I would love to get some help. Even if one person wants to participate I'll be thrilled.
Each test takes quite a lot of time so we can get more results if we will work together. I choose to run tests for 10 hours as it will give us more accurate results than anything shorter. 10 hours seems to be right as smartwatch still can be used during the day and whats more important, battery can be run down before recharging and testing.
Watch always on (6th watchface) Wifi/Network/BT(unpaired) off - 10h: 22%
Watch always on (6th watchface) Wifi/Network/ off - 10h: 23%
Watch always on (1st watchface) Wifi/Network/ off - 10h: 23%
Watch always on (Watcher) Wifi/Network/ off - 10h: 25%
Watch off (6th watchface) Wifi/Network/BT off -10h: 9% Comment: I was expecting less usage. BT in GearS was still ON as it can't be turned off (but not connected)
Connected via Bluetooth (Watch/Motion/WiFi off): 10h 11% Comment: Apparently when it's paired with phone (sync) does not make much of the different
Connected via GSM without data (Watch/Motion/WiFi off): 10h 18%
Connected via GSM with data (Watch/Motion/WiFi off): 10h 20%
Connected via UMTS with data (Watch/Motion/WiFi off) - 10h: 20%
Talk time on UMTS with data (Watch ON, Motion off, WiFi off) - 2h21m Screen was lighted up few times just to have a look what's going on
[By saying BT off means that do not keep it connected to your phone]
[While connected to Bluetooth or via cellular network make sure to deactivate all notifications in GearManager App - test will be useless if any notification will be delivered to the smartwatch]
To do a test just after a day of use charge your Gear S fully. After reaching 100% still wait approx 20-30min, choose what test you want to participate, disconnect from a charging cradle, switch the screen off and set an alarm to check it back after 10h
Observations:
Having a "Clock Always On" is not that bad idea. During 10h test it consumed 13% more than without it (6th watchface). So we can assume that during all day (approx 16h) we're loosing only 19-20% of juice. Is it bad? I don't think so... especially because you don't need to light up the whole screen just to check what the time is - which will consume some energy too... In the end of the day it still depends of that how often you need to check the time. If you are doing that very often, than "Clock Always On" is... lets say... more energy efficient solution (and looks much better than dark screen).
The only problem with "Clock Always On" is that, almost every touch, raindrop, wet sleeve triggers screen to turn on and it's very inconvenient for the battery life and it can messing around in the interface - it happened to me when i was walking in the rain.
In my opinion touchscreen should be inactive during that mode or even to give such an option to tick in the settings menu.
Thread to that issue http://forum.xda-developers.com/gear-s/help/how-to-stop-accidental-cuff-calling-t2991565#post58596115
What is your brightness setting when your clock is on? If it's set to "auto," then is this being done in a dark room or a bright room?
Seems like losing 20% of battery life after 10 hrs of clock mode on is reasonable at average to high brightness. I wouldn't mind a "clock always on" mode where the brightness is set to min and then the display brightens up when I either touch the display or wake button.
I currently use my Gear S with the "wake motion on" and I'm ending a day of 12-14 hrs of moderate use with 35-50% of battery.
My settings:
Gear S only connected to phone via BT
Wifi off, mobile network off
Set vibration intensity to low (don't see many people talking about this option)
minimal notifications
minimal apps
S voice to wake is off (have to turn off via S Voice settings on Gear S)
Minimal black clock face (batteryclock app)
Screen brightness to auto
I periodically go in to close all recent apps.
I'm always setting brightness to auto but in this case it doesn't really matter.
If you set to max or min ClockAlwaysOn is on with the same level of brightness.
On auto brightness there is no reaction too. Regardless if it is outside in a sunny day or in pitch black basement.
Also during a test just after disconnecting from a charger I'm switching off the screen with a button and after 10h wake it up with a button and straight check battery level. So brightness level won't change much for these 3-5secs

Screen Resolution Changes

Hello,
After all, I had a amazfit pace smarth watch and joined you. So, hi everybody.
After a one day usage, i noticed that (i updated to latest version 1.3.3a) screen resolution of watch changes for a while. If you double tab screen it turns normal, for a few seconds later screen turns worse resolution. Do we have any option to keep same good resolution always?
Thanks,
It's not the resolution change, but color pallet change. Once you double tap the screen you wake up the watch and you see the full color watchface. After few seconds watch goes into power safe mode and in this mode screed has only 8 colors to safe energy

Do we have any option to stop that changing? Custom rom or other mod etc can be possible?
No, this is the reason why the amazfit has that amazing battery life.
If you want a watch that has 12 hours of battery life with a full on display buy a Garmin/Samsung/...

It would be great to make an option for that. They could write easily that kind of command into the os.
I think it can decrease battery life but not too much because screen type is not same as Samsung/Garmin etc...
The Bip doesn't have that pattern and has amazing battery life...
At least a way to enable full watchface it when backlight is ON : as a nurse, i use seconds a lot de check pulse of my patients, have to double tap with my nose to see it... =)
If someone with a rooted watch could post result to these commands to see what we can tweak (among all settings) !
Code:
adb shell settings list system
adb shell settings list global
adb shell settings list secure
Thanks, on, 133a, not results...
Can't you go into settings in the watch, and turn "always on" feature?
Swipe down, tap settings, tap common, scroll down, tap backlight, choose "always on".
But then you have to double tap or press button always, to get into power saving mode.

There is no changing happening by these options. Always 8 color seems. Interesting :/

[DISCUSSION] Xiaomi Mi 9 battery life saving tips

Xiaomi Mi 9
Battery life saving tips
- Discussion - ​
Presenting a few tips based off personal experience that can help squeeze out those extra few minutes/hours of battery life from our device.​
Please note:
This is not a science and what works for some may not work for others. There are many factors involved in having good battery life and one person’s 1 SOT (screen on time) may mean completely different usage to another’s. For example, 1 hour of internet browsing will of course be less battery-intensive than 1 hour of processor-hungry gaming. So bear this in mind…
I am running the weekly Xiaomi.EU rom (9.4.11 at the time of posting) and so some of these settings/features may not be available on other versions of MIUI.
Some of the below will require. Some users prefer not (or can’t for whichever reason) to root and so you’ll just have to skip those if so.
Lastly, this thread is intended on being a work in progress and I welcome comments/suggestions/additions on the content. These are the settings that I adhere to which I believe, as well as most users, which are useful to aid battery life. Some tips may help out significantly, some may just offer a slight increase. Some may not even help at all and may just be placebo!
If something doesn’t work for you or you greatly disagree, let’s discuss it…​
Network settings + roaming
There are various settings which are known to help out with the notorious Cell Standby drain etc. such as:
Preferred network type (found either by Settings – SIM cards & mobile networks – Sim Card Settings - Preferred network type OR by dialling *#*#4636#*#* via your phone app). Users in the EU find that setting the network type to GSM/WCDMA/LTE or WCDMA/LTE (on both sims) can help stop the device look for network frequencies that it’ll never find, such as the TD-SCDMA etc. You can Google what frequencies your network provider uses which can help you decide.
VoLTE (Settings – SIM cards & mobile networks) – there may be some debate over this one, but it can be said by having VoLTE enabled, whilst calls will be clearer, it will use 4G which is that bit more power hungry. Therefore some testing may be preferred if you’re a frequent caller. I personally have this on without and haven’t tested it fully, but I’m also not a huge caller.
Make calls using WLAN (Settings – SIM cards & mobile networks) – by using WiFi for calls this should be more battery efficient than using mobile network data.
Data roaming (Settings – SIM cards & mobile networks) – I tend to keep Overseas data roaming off when I’m in my home country with the thought that it prevents the device from looking for networks it won’t find. As for National roaming, I have this kept off too normally as I don’t travel around much generally, so again to prevent it searching for alternative networks when it already has a strong signal.
System settings
Here we have several system settings/features that may be used on a day-to-day basis but may not be needed to be enabled at all times. Generally speaking, having something turned on all the time yields benefits for convenience but at the cost of battery life, as seen below.
Wifi / Bluetooth – both of these can be regarded as similar, in the sense that by having it enabled all the time it can connect automatically without your input. For example, if I leave my WiFi on when I leave my home it’ll automatically reconnect when I come back. Great! However, throughout the entire day if it doesn’t find a known network it will constantly be looking for one, draining battery. Not so great. Therefore if the convenience of not having to turn your WiFi on/off is your preference, then leave it enabled. Though if you know you’re not going to be connected to a network, then some manual control may be preferred. The same rules apply for Bluetooth devices.
WiFi & Bluetooth Scanning (Settings – Additional Settings – Privacy – Location – Scanning) – this can be a big drain I have found and is usually activated when you have High Accuracy location mode activated. Again, it comes with its benefits of providing higher accuracy, but with some battery cost. By disabling both WLAN and Bluetooth scanning, extra battery life can be saved. There are some apps I’ve found that force you to enabled High Accuracy mode, so just remember to switch off these scanning settings once again if so.
GPS & location accuracy (Settings – Additional Settings – Privacy – Location – Location mode) – I personally don’t mind just using Device only and keeping this on all the time. As whilst like with Bluetooth as mentioned above, if I know I’m not connect to my Bluetooth speaker for example, I at least like to open Google Maps and it find me straight away rather than toggling GPS on etc. Personal preference of course, as with all of these…
NFC (Settings – More) – as with WiFi and Bluetooth settings, if you’re not using it and don’t mind the manual toggling on/off as needed, then disable and do just that.
Hotspot (Settings – Portable Hotspot) – as above really, as this could be a big drainer if left on. Luckily there is a setting (Turn off hotspot automatically) which can help with this.
Display
A massively subjective aspect of using your device and only you know what you’d rather have and what you;d rather be looking at. Just as we know, a higher brightness level will result in high battery drain and the screen can be the biggest drainer of the all, so choose wisely if you’re trying to conserve some juice.
Screen brightness (Settings – Display – Brightness level) – I personally have it set to manually controlled, as I find the auto-brightness not to be very smooth, at around 20-30% indoors and perhaps up to 100% outdoors. I believe that manually controlling brightness preserves battery as it of course doesn’t use the ambient sensor and brightness remains the same, rather than jumping up and down reacting to light levels.
Ambient display (Settings – Display – Ambient display) – functionality of having the ‘always on display’, but at the cost of some battery life. There is the scheduling that you can use to help with this, but personal preference whether you want this on or not. I personally don’t, though at times I’m tempted to given the notification light, for me, isn’t that practical.
Contrast and colours (Settings – Display –Contrast & colours) – it can be said that Standard will be the most battery friendly, Increased Contrast drawing that bit more power due to the increase in contrast and Automatic Contrast using the most given it will use the sensor to optimise contrast based off available light. I personally have it on Increased contrast and I’m happy enough.
Double tap/raise to wake (Settings – Display – System) – with both of these sensors will be used for the convenience of tapping your screen and raising your phone in order to wake the device. This may be handy, but be mindful that such convenience will come at the cost of the sensors running using up some battery.
Themes
Another subjective aspect of your device is you can make it look. The suggestion here is for black themes to be applied where possible as on our screens black images use less power, as noted by Google. Though indeed black theming isn't for everyone so this suggestion, as with all of them, is purely up to you.
Night mode (Settings - Additional settings - Developer options - Night Mode) - enable night mode (Always on) to turn on MIUI system-wide black/dark theme, such as the dialer etc. *If you don't know how to activate Developer options, see here
Substratum and Swift Black - I highly recommend using this theme with the help of Substratum, though indeed only available to rooted users. Be sure to follow all the required steps to get Substratum working, such as installing the Magisk module etc.
Battery & Performance
Here are the various system battery settings which aim to preserve battery. Some perhaps more useful than others!
Adaptive Battery (Settings – Battery & Performance – Use Adaptive Battery) – this claims to limit battery for apps that you don’t use often, which I have enabled, though as will be seen below some further manual control can be done.
Battery saver / background app restrictions (Settings – Battery & Performance – App Battery Saver – Choose apps) – here you can select per-app a choice of 4 background restriction settings. It’s time consuming, but it’s worth going through each app (note: use the 3 dots in the top right corner to Show system apps) and choose the restriction settings, if any, to be applied. Generally speaking, if you want notifications to come through from it (like WhatsApp) or you don’t want it being shut down in the background (like Spotify) then choose No restrictions. If you’re not so bothered about it and want the system to lay down the law on battery saving, choose Restrict background activity. There are settings in-between, like Battery Saver and Restrict background apps, but I’ll leave you to play around with those ones.
Battery Optimization (Settings – Battery & Performance) - this has several options to save battery ranging from adjusting screen brightness, turning on Battery Saver, turning off GPS etc. This can be used however I prefer to manually configure the settings, so this will be up to you…
Scenes (Settings – Battery & Performance) – here is a ‘smart scene’ called sleep mode which apparently will detect when you’re sleeping and close down apps, restrict NFC etc. I personally have this disabled as again I manually adjust such settings
Auto-start (Settings – Manage apps - *select app* - Autostart) – another useful option is to go through each app you have and disable the autostart, which could provide additional battery savings preventing apps from starting up in the background
Debloating / removing system apps
Lots of system resources can be freed up which can result in added performance and battery life. See the extremely helpful thread by @SirTAVARES who created the Debloat Applications (No-Root) thread.
I personally have used the above guide to remove a lot of pre-included apps, even on the somewhat pre-debloated Xiaomi.eu rom. Without root you can use ADB to remove apps and they won't reappear when you update your rom. They will appear back if you perform a factory reset, as they are not fully uninstalled.
Furthermore, with root you can remove the app from not only the user area but system area too. Check out the thread for more info on this.
Lastly, apps like System App Remover Pro can fully uninstall system apps, with the option to use the Recycle Bin option should you wish to restore
Battery draining apps and alternatives
It can be said that some apps are notorious for being big battery drainers, such as the official Facebook app. I’m not a huge user of some of the other apps, like Snapchat, Twitter etc. and to be honest I generally favour webpage versions of some things for example I don’t have the Amazon shopping app, I just use the web page version, saved as a bookmark on my home screen. The general tip here is if you are going to use an app, be sure to go through its settings and adjust notification settings/frequency. For example, I do have the Sky News app however set it to not notify me of news, the same for Yahoo weather. So tweak accordingly. If you have some good alternative app suggestions then I’ll be happy to include some here, but for now I’ll just start with…
Facebook – I use Folio for Facebook & Messenger which is a nice lightweight 'Facebook wrapper' in that it uses the Facebook webpage as the basis for the app. It also has a functional messenger included so no need for a separate app.
Battery monitoring apps - apps like GSam Battery Monitor and BetterBatteryStats can be useful in detecting the high draining apps, so could be worth using one of those in an effort to identify them.
Magisk modules
There are many Magisk modules out there which aim to solve battery. I only use one, which I’ll list below, however please feel free to make suggestions for inclusion in this section. I know that there are some like Greenify, Amplify (when using Xposed) etc. that could squeeze even more juice out of the device!
Universal GMS Doze - helps put Google Play Services to sleep to save some battery. I use this with no issues/impact on Gmail, Play Store etc.
Other system settings
Sync (Settings – Sync) – as with per app settings for notifications/sync frequency etc. settings, it’s worth checking here to see what apps are auto-syncing data. You can turn them all off (I believe) via the Auto-sync data toggle, or check them out individually via this menu setting. *Note: I have removed Mi Cloud etc. and so I don’t have any of that running in the background, but that’s up to you.
Vibration (Settings – Sound & Vibration) – now this is likely a very small potential for some battery savings but still worth noting. You can adjust the Vibrate on tap option ranging from Off/Light/Medium/Strong, which I’m sure someone who has it set to Strong will be using that tiny bit more power than someone who has it set to Off. Your call….
Permissions (Settings - Permissions - Permissions) - it's worth going through here to monitor per-app what permissions are being used. Some apps may not like being prevented using certain things and it may break some functionality, but it's an extra method in reducing potential usage, such as hardware usage, for an extra saving. For example, an app may try and use GPS each and every time you open it or even try running it in the background. If you're willing to, preventing it from doing so may help save some battery.
Authorization & revocation (Settings - Additional settings - Authorization & revocation) - here you can revoke some access from apps. I have stuff like Security, Downloads, Battery and performance and Settings listed here, all of which I've revoked with no noticeable negative consequences.
Fingerprint icon (Settings - Lock screen & password - Manage fingerprints) - another very small tweak for a potential very small saving. The setting is Show fingerprint icon when the screen is off (which is present on Xiaomi.eu 9.4.11) and by disabling will prevent the icon showing. As the icon is displayed by the screen, by turning it off it'll naturally save the power it takes to light the screen up, which as you may have noticed, it lights up with the tiniest movement of the device! I keep it on as I like it and battery doesn't seem to be greatly impacted - but this thread is about squeezing as much juice as possible, right?!
Recents and 'Clear all' - not a system setting but a little thing to do, is to open up the Recents menu and use the 'X' button to close all running apps, or swipe individual to close certain ones from running in the background. Now, it is the case the apps stored in the RAM aren't necessarily using battery, but this is still useful to stop apps that are running and active. Definitely a debatable one, as the argument against doing this is that it then uses battery to reopen the app, so perhaps just test it out and see for yourself.
Last but not least....
Now this last little tip of mine is certainly one that can be debated, but I do it nonetheless...
Remember, none of this is advice as such, it's just what I do to keep myself sane in knowing/believing (philosophical debate here?!) that I've done all I can to maximise battery life.
What I like to do is when installing a rom have the phone charged to 100% before doing so. This originates from the days of believing that batteries need to be calibrated. There is definitely lots of research that states it may not be needed and a simple Google search can reveal research into this, but it's something I like to do anyway.
So essentially my method regarding this, needed or not, is:
Charge phone to 100%
Update rom
Use phone until it switches off at 0%
Charge phone fully to 100% without interruption
I'm not stating this is needed, it's just what I do. Take it or leave it! I'm aware that there is science behind not allowing phone batteries to die at 0% in order to prolong the life of it, but again, it's just what I do and it works for me.
Your call!
That is it for now. As mentioned I highly welcome your comments and suggestions for adding to this thread so please do let me know if any questions etc.I'm purposefully not showing my SOT/battery stats as they won't be useful to anyone - the above tips are here for that!​
Nice thread.. we need something like this. Thanks

Compiled everything, except the overlay of android system (it remains blue accent for some reason) phone overlay and system ui.
Thank you for your advice
With all you have done for your setting, Could you share us the battery performance please?

As it as been say, the performance would be pretty different from different user (wifi, Bluetooth usage, nfc, ect) . I can give you an example, I done almost all optimization that has been given in the thread. I have Bluetooth activated all the time cause of my amazfit cor.
If I'm at home an only use wifi and if I often use my phone with 25 % brightness I can have 10 hours sot. But in real life use, with bad mobile network, usage of mobile data, phone call, screen at 100 % on outdoor use, I can only have 4h30 of sot.
Dépend of the usage and what you done with the phone. Personally, if I have a smartphone, it's to use use it. If you desactivaye all network, keep battery saver, keep your screen at 20 %, buy a Nokia 3310 ?

From what you said, it's seem to be good for standby draining. As I normally use the phone when I have the break from 9am to 6pm only 2 hrs screen on, My current phone battery are lower than 40% in the evening.

OK guys here is some stats for you, see attached. Been off charge 21 hours with almost 5 hours SOT down to around 40%.
Going strong!
Hi, also running xiaomi.eu but can't find the screen of your last screenshoot. Mine under battery and performance looks completely difderent

I'm using Nova too, but I've never seen that screen before. Where can I find it / activate it?

You can add it to the home screen as a shortcut:
Long press empty space on home screen - add widget - shortcut activities (drag that to home screen) - Settings - Battery and Performance (PowerUsageSummary)
Then you'll have a shortcut to this battery info screen
10hrs39mins, best yet! On WiFi all day just light chrome/xda/reddit etc.
This is on latest RevolutionOS rom
Has somebody noticed that email apps (like bluemail, gmail...) make the phone never sleep totally ?
I often have 15 hours "held awake" in my gsam battery stats! [emoji33].
If I kill the email apps then my phone sleeps MUCH, better.
I tried several mail apps..same result.
Is it because of Android 9 or Xiaomi?
On my other devices (Android 7 and 8) I don't have this problem with the same apps...

Tips to For Increasing Battery Life on the Galaxy Note 10

Sooner or later you will find yourself looking to save some battery life. here are a few ways.
5 Tricks to save battery life:
1: Change to a Dark screen or theme: 0:22
2: Put apps to sleep: 1:39
3: Turn-down display resolution and Screen timeout: 3:07
4: Turn off unnecessary features: 4:36
- Wifi
- GPS
- Bluetooth
5: Switch off Vibration and Animations: 5:25
6: Ultimate Battery saver: 7:00
The video shows how to do these if you're not familiar with the settings on the phone. Feel free to add to the list.
If you have anyways of saving battery ( not turning the phone off...) then share it.
Debloating could potentially save some battery. Turning off Wellbeing as well
agreed with other poster, you are crippling the phone with those features disable. Although, I have been testing dark theme and it does help with battery.
I also went into Settings and search for Usage data and disable most app usage data for apps and it gives a performance boost. I also scaled down animation from 1x to 0.5x in dev option.
#8. Do not your phone
I use Nap Time by Francisco Franco which helps especially when you're not using the phone, just need two adb commands to work. Have also debloated quite a bit and not having any troubles with battery life.
For me, an overnight charge gets me through a full day of normal usage, so I don't bother with many power-saving sacrifices. I use AOD and maximum screen resolution, with GPS, BT, & NFC enabled; I don't engage general power-saving, or debloat or disable apps or services. But I do avoid keeping the screen brighter than necessary, I use Night Mode (dark theme), and I enable automatic control of WiFi (turns on when I'm near a network I use, otherwise turns off).
If I'm traveling & sightseeing, constantly using the phone for navigation, photography, and web browsing, and running through a VPN when on WiFi, then the battery only lasts half a day, so I carry a charging brick to supplement it.
I work where I have a lot of free time but no way to charge my phone so haveing a few ways to save battery helps. I do have a battery pack but sometimes I just don't feel like carrying it and a wire.
When you are out of the house and will not be around wifi for a while, turn it off. It constantly searches.
It's not just a couple things... it's many.
Depending on the user and the variant, what works for some will not work for all. Dependencies... know what they are or learn.
If you're still on Pie DO NOT upgrade as it will make optimizing harder.
My SOT on my 10+ is 7-11% @hr 7% for web browsing and 11% for vid streaming. It rarely goes above that... if so I go looking for the cause.
Google play Services is disabled unless I need it running.
Wifi, always disabled.
Bluetooth as needed.
Manual brightness and syncing except for text.
All power management is disabled except fast charging is toggle off. CPU/display power mode set to optimize.
Google Backup Transport and Framework always disabled.
All cloud crap and carrier, Google, app, Samsung feedback disabled.
Google Firebase, Assistant and Quick Search always disabled.
All emergency services junk disabled.
As much of Knox as possible.
All MS crap.
All AT&T junk except texting.
Much of the Samsung bloatware is package blocked but some Samsung apks are useful.
Package Disabler and Karma Firewall lock it down along with a custom settings configuration. About 86 packages are always disabled with about 7 that are toggled on/off with the PD MDM widget.
