There are a few things you can do that will help your battery life and performance...
Performance
· Do some graphical tweaks...
1. Install Spare parts
2. Set Window animations > Fast
3. Set Transition animations > Fast
4. Set Wifi sleep policy > Never While Plugged
· Adjust the Android memory management...
1. Install Autokiller
2. Menu > Presets
3. Most people have best results with 'Moderate' but you could also try 'Optimum'
4. Menu > Settings > tick 'Apply settings on boot'
Battery
· Wipe your battery stats...
1. Allow the phone to discharge completely
2. Boot into recovery (hold Home and press On) plug the phone in if you don't have enough charge to get into recovery
3. Select Wipe > Wipe battery stats
4. Go back and Reboot
5. Leave the phone to do a complete charge (preferably over night)
· Adjust your radio settings...
1. Go to Settings > About phone > System updates > Update PRL (it's normal that the phone process will force close at this point and the radio will reboot)
2. Go to your dialer
3. Dial *#*#INFO#*#*
4. Click 'Phone information'
5. Scroll down to the first dropdown selection and set according to your preference below...
· WCDMA preferred (default) - This will automatically switch you between G/E/3G/H depending on the best signal available by constantly monitoring all signals. This uses the most battery.
· WCDMA Only - If you only want to use 3G/H (3G) and do not want to use G/E (2G) select this.
· GSM auto (PRL) - This is the preferred option as it will allow you to use G/E/3G/H but uses the PRL list on your phone (provided by your carrier in the PRL update) rather than constantly monitoring all frequencies thus saving your battery. This may not work with all carriers if you have difficulty getting mobile data in some areas you will have to use one of the other options.
· GSM only - If you only use G/E (2G) select this (it's the same as selecting '2G only' through the settings menu). This option uses the least battery.
Upon making your selection the radio will reboot and the setting is saved, so just back out back to the dialer and you are done.

Don't use any Taskiller
And dont look at Battery level again and again, it will drain battery faster.
What is the different between task killer vs autokiller? Thanks for your advices
We use task killers to manually kill apps and auto killer kills the task by themselves on precondition basis.
But dont use any taskkillers cos android works exact opposit than windows do. Windows need free ram to run effectly whereas android use ram as cache, more its filled more effectively android will run.
Press thanks if i helped.

Your battery facts need a little refreshing.
1.Wipe your battery stats
Today's myth debunking:
"The battery indicator in the status/notification bar is a reflection of the batterystats.bin file in the data/system/ directory."
No, it does not.
This file is used to maintain, across reboots, low-level data about the kinds of operations the device and your apps are doing between battery changes. That is, it is solely used to compute the blame for battery usage shown in the "Battery Use" UI in settings.
That is, it has deeply significant things like "app X held a wake lock for 2 minutes" and "the screen was on at 60% brightness for 10 minutes."
It has no impact on the current battery level shown to you.
It has no impact on your battery life.
Deleting it is not going to do anything to make your more device more fantastic and wonderful... well, unless you have some deep hatred for seeing anything shown in the battery usage UI. And anyway, it is reset every time you unplug from power with a relatively full charge (thus why the battery usage UI data resets at that point), so this would be a much easier way to make it go away.

2.Allow you phone to discharge completely.
Tip #2: Avoid allowing your device to discharge completely
Every wondered why your modern phone, PDA or iPod is able to cheerfully tell you that “Your battery is now exhausted” for several seconds on its brightly-lid LCD screen before switching off? The reason is simple; there is an artificial circuit that shuts off the device when the charge in the battery is too low.
This extraneous circuit is built to protect from the damage that could result if the charge of your lithium ion battery falls too low. If you still don’t get it: if the charge of your lithium ion battery falls too low, the battery can get irreversibly and permanently damaged. So since Lithium Ion has no “memory effect”, it is better to simply charge your portable device as and when you can or remember.
To set your mind at ease, a “charge cycle” means a single iteration of depleting followed by a re-charge until 100% of battery charge. If you consume 50% of your iPod’s battery on day 1, recharge to 100% at night, and do the same thing on day 2, then you would have just finished up one charge cycle of its battery life.

My X10a used to give a day worth of battery life when I was on Android 1.6 after upgrading to 2.1.A.0.435 it almost got doubles 2 days. A week back I installed black theme using xRecovery and JIT (I didn't take backup before installing it ).
Now the battery is good for 10 -12 hours only. I checked the battery usage, it is show 60% cell stand by and 20% display, my usage doesn't change at all.
Can any tell me solution without doing the repair will greatly appreciated
Thanks
Try going into xRecovery menu and do " wipe battery stats ". Could be you've turned up the brightness, and your display is eating battery?
Maybe you already do this, but these next ones improve battery life in general. Not that it would explain your change... Use the app APNdroid to disable data when you aren't using it. It has a no/off toggle widget for the homescreen that works great. Set WIFI to "off when screen off" along with APNdroid, and use Advanced Task Killer app set to aggressive, medium security, and "auto kill when a screen off". Set all system apps and any apps that you always want running to "ignore" auto kill.
There is argument that task killers actually do more harm than good or kills battery, but that is if you didn't set it up right. At least on 2.1. New versions of Android don't need task killers. If you don't like task killers, skip that. It's better to have no task killers at all than to have one that's set up wrong. Never set task killer on a timer, like every 30 minutes.
When I did all these things I still have 30%+ the next day if I forget to charge it at night with HEAVY use. Before I didn't always make it through the day. Hope this helps.
Thanks for your answer.
I tried wiping battery and then what I found is my phone is using much more power standy mode. The application have not changed and I already use advance task killer in aggressive mode
can JIT increase power consumption in standy by mode?
Don't know if this will help, but try using a fresh download of JIT custom zip. Then going into xRecovery/advanced options and wipe Dalvik Cache and then reinstall JIT. Also, try disabling task killer if you are still having problems.
i've had my x10 for 9 months and last month i noticed a change in my battery life even when i haven't made any significant changes to my normal usage (and settings). my old x1's battery lasted about 11-12 months... and i'm a moderate to heavy user. so it could just be your battery beginning see it's way out.
agentJBM:
I tried reinstalling after wiping Dalvik Cache but this didn't work, I'm stilling seeing drop in battery a percent a minute then phone on otherwise cell standby using the battery.
I guess I need to start from repairing again and installing JIT. Only thing I can think is that JIT is for global ROM but I had Canadian Rogers ROM
if that didn't work then I'll follow azian_advanced advise and order a new battery
While you're at it, see if you have the same problem before you enable JIT after repair software. That will give you an idea if it's the battery.
Also, try the procedure in the thread titled "[Guide] X10 Battery Calibration" found in the general section. I'd provide a link, but I am on my kick ass X10a.
Repair made big difference, I installed all my apps but haven't configured by emails yet but drop of 5% in whole night versus 90% drop earlier. I haven't installed JIT yet and i thinking leaving it alone for now
its crazy how jit seems to effect each phone so differently
I'm not responsible for any problems caused by this on your device. It's your choice to apply these simple tweaks to your phone!
---------------------------------------------------------------------------------------------
[These apps are NOT paid! Only setCPU is paid, you can get it from the Android Market! (All apps provided here are downloadable in de Android Market)]
---------------------------------------------------------------------------------------------

If these simple Android Market apps, cause any problems on your device it means you've got something unstable installed on your device! I never had problems with Autokiller and AutoRun Manager on any ROM.
Hey,
In this thread I will show you how to get a REAL boost on your Sony Ericsson XPERIA X10! This method could also improve performance and battery life on any other handset. This is compatible on Android 2.1, 2.2.1 and 2.3.x. (This way of boosting performance is without Systcl config! I suggest you to uninstall Systcl config, since it doesn't improve anything for me (and maybe for more persons here). I don't recommend you to use Autokiller on WolfBreak his CyanogenMod 6.1.3. He has already implemented these settings and also don't use this on Gingerbread Custom ROMS for the x10. Autokiller is not stable on it anymore. Just wait till I report more about it.
This method made me lose 0-2% in 9 hours on WolfBreak his Cyanogenmod 6.1.3 and ALL 2.1 ROMS! These simple apps, did improve my performance and battery life!
---------------------------------------------------------------------------------------------
Lets get to the point
Download this and this package, put in on your phone and install them!
Lets config it now
---------------------------------------------------------------------------------------------
Open Autokiller.
Go to the tab Memory limits.
Now put these configuration into the 3 boxes. (If these values cause problems you can try lower values I will provide)
Hidden app: 150
Content provider: 160
Empty app: 170
Now press on Apply.
Lower values (Only use when you get problems with high values):
Hidden app: 82
Content provider: 90
Empty app: 92
Now press on Apply.
(Don't put these values listed above higer. If you do your device can start to malfunction)
Now press on the Menu button on your Device and tap on Settings. Now make sure Apply settings on boot is turned on! After turning it on, press on Advanced system tweaks. Now make sure that Battery and Memory management are turned on!
Exit Auto Killer by pressing the menu button and reboot your device.
---------------------------------------------------------------------------------------------
Now open Autorun Manager.
Now make sure every service that is listed in the tab Basic you don't need is turned off! Make sure you only turn off things in the tab Basic! After doing that, exit Autorun Manager with the Menu button and reboot your device.
---------------------------------------------------------------------------------------------
This configuration only effects you device when your screen is turned off. Don't expect with this setCPU very big changes! But there will (must) be some changes in battery life) (Some people had big changes)
The settings here below won't cause any lag when coming from sleep (atleast for me). Even with heavy apps.
[To get the XDA-free version of setCPU take a look at this post. Credits for telling this are going to DooMLoRD]
This step has a payed app. You can buy it from the Android Market. The app is called ''setCPU''.
Buy setCPU from the Android Market. Now open it and do the following:
Tap on Show Other Frequency Sets and tap on the list on Nexus One/Snapdragon [QSD8x50]. Put
Now press left in the corner on the tab Main. Put in the scaling bar the maximal frequency on 998MHz. Now put the minimal frequency on 245MHz.
Now press on Scaling and choose out of the list Ondemand, after pressing on Ondemand turn ''Set on Boot'' on.
Now press on the tab that you can find next to Main. It's called Profiles. Make sure that ''Enable'' turned one and Notifications turned off. Then press on Add Profile. In the Edit Profile window you have to put the following settings:
Profile: Screen Off
Max: 384MHz (Don't put it lower or it can cause malfunctioning!)
Min: 245 MHz
Scaling: powersave
Priority: 100 (High)
Then press Save.
Then reboot your device and enjoy!
---------------------------------------------------------------------------------------------
Your x10 is now fully optimized with a few simple apps! Not only the battery but also the performance! Most people think it should improve battery, it's only more for performace. It can improve your battery.

Interesting. Hard to believe the 0% in 9hours. I think that's massively exaggerated. Cellular standby at the min uses 0.5%-1% per hour. Even if you didn't turn your screen on during that entire 9 hour period, you would still have a drop of about 5%-10% in batt life.
But I'll bite and give it a test.

I didn't touch my phone in those 9 hours. I was just sleeping with alarm on
Looks interesting, but shouldn't be in the development section.

Yes, that's what I was saying, even then, cellular standby would eat up 0.5-1% of batt life per hour. Could be much higher if you're on a fringe area of your nearest tower among other factors. In a 9 hour period, in just standby and in perfect conditions it should have at the very least dropped 5%.
I mean this is just the nature of the beast with devices. Only way around this would be airplane mode, phone in sleep mode and not being used at all. Then the phone is pretty much dead and you might as well just have it turned off. Even then phones that are turned off actually bleed batt life. Albeit at a much slower pace, they still discharge while completely off.

So after some research and Googling, I discovered that "Killling" your app is only worse or has no effect for your battery life. Even using apps that "save" battery only harm it even more. I've been told these were the fundamental things to save battery ever since I even got my hands on a smart phone.. Guess I've been asking the wrong people.
So, what are real ways to save battery? I'm a heavy phone user, often surfing the net or watching Netflix on the go. Dimming my screen is not enough, are there any other techniques to prevent my phone from dying? I've got an Android 4.
If you're rooted:
Underclock
Undervolt
Change cpu governor/io scheduler
Flash different ROMS and kernels
Change your modem
And a few more.
Not rooted:
Use screen filter? Lol.

Get bigger battery?
Turn thing off lol only kidding but turn off auto updates such as news etc
If you look at your battery stats, under settings, you'll see what uses the most battery. Usually I find that my screen uses around 70% of my battery, but if you have something else high on the list you might have a "rogue app" preventing your phone from going into sleep mode.
If your screen is the culprit you can only save 10% or so by throttling your CPU etc. The only way you can make real savings is by reducing screen brightness.
Easiest way to save battery is use gemini app manager to stop apps being able to autostart when you don't want them to as then you don't have the os having to kill off unused apps to make more free ram.
For example a lot of apps can autostart when your wifi goes on or off, when your 3G signal drops etcetera including things like facebook or google play. By changing auto start for such apps you don't have to run a task killer which also saves battery.

i use the aokp rom milestone 4 atm, and i also have come accross a fantastic battery app called "Badass Battery Monitor". its free and details very very specifically what apps are using the battery most.
I have managed to increase my battery by rooting out the apps i dont use that are using prescious power...
Also, turning off useless app permissions for apps theat really dont need them and work perfectly well without them will also save on power massively. for this i use "LBE Privacy Guard" works an absolute charm
I have widget where I can turn off Internet connection, set brightness, GPS etc. Internet stand-by mode uses damn much battery... And when you don't use Internet, you can put on 2G, it also saves battery.
This may not benefit you if you are a heavy user but I find the feature on my Droid 3 that turns off 3G after 15 minutes of inactivity saves battery and also saves data. Not sure if this is a standard Android feature or if it would even benefit you.
Here with LG P990 and I don't have option to turn off 3G aftre some minutes... but if/when you didn't need high speed you can choose only 2G network (for example when needed receive only notification): this save a lot your battery.
Moreover you can verify battery consumption to see if there are autostart apps from your vendor than have heavy power consumption (for me there was OnScreenPhone) and use gemini app manager as explained previously.
In the end you can find out custom ROM for your device usually optimized for smoothness and power consumption.
First apps I download when switching to a new Rom to get a little control on battery are
Adfree- Get rid of ads, they eat a bit of battery.
DroidWall- Control what apps are able to access Internet under separate "Mobile Data" and "Wifi" Conditions.
Screenfilter- Dim the screen below factory settings.
LED's hack- Turn off the Softbutton Backlights (home/menu/back/search), even though they don't seem like it may eat up your battery, it is an extra 'light' that's on, even though it may be minimal, it's still drawing power.
Also, It maybe just a Photon thing cuz of the Pentile display but I always use if not completely Black background image, a dark one because the 'lighter' or 'whiter/colorful' images take more battery, same reason I always look for 'Inverted' or black themed apps too.
Turn OFF any 'Haptic feedback' settings on your phone (Keyboard, Phone DialPad, Screen/UI Interactions, etc..)
For Calls (Ringtone) and Notification settings, don't have them set to 'Ring and Vibrate' or just 'Vibrate' because the Vibration Mechanism will eat alot if battery. Some may argue that the Notification 'Vibrate' setting and even the Haptic feedback (which does in fact use the phones Vibration mechanism) would not kill battery because it's a 'quick' or 'minimal' use (depending on use) and but if your keyboard had the Haptic feedback on, thinking of how many times your touch the keyboard for even on Text message, try will add up and help kill the battery.
Turn OFF any/all Homescreen/UI Animations
Turn OFF any Auto Sync setting and instead have APPS sync in a specified interval, (Of course Depending on how important the information that's being pulled like Email) , Could be set to like every 4 hours to sync an so on.
Manually input Date/Time settings instead of "Get network provided values" because it'll be one less thing pulling from Internet.
Set Screen Timeout to 30 Secs and Never have Auto-Brightness set, instead use a brightness toggle of some sort (Stock 'Power Control' Widget works well) to only have it as bright as you need to view in current conditions.
Open the Google 'Talk' application and uncheck the 'Auto log-in' setting, and then 'Sign out'. For some reason this always runs in the background and eats alot of battery.
If I think of more things ill post them
Hope these tips help, if they do don't forget to hit the thanks button thanks.
MoPhoACTV Initiative
There are many ways...
Switch on WiFi, 3G at only using, and close the not using application, decrease display brightness etc...
And if you root your phone, you may change CPU governor, or build.prop tweaks, script tweaks... Or change to custom kernel or custom ROM.
I forgot that 'LED's hack' is not available in the market anymore, I attached it below.
i hv just downloaded screen-filter lets c how that works...
Juice defender
Try JuiceDefender by Latedroid. It helps a lot to turn off things you don't need when you don't need them. Sorry I can't post the link- I'm new to XDA
my experience:
undervolting does not help much. you have to test a lot for only a little bit of improvement.
in my opinion you will not really remark it.
but what helps, i think, is set cpu speed, if possible. for example i use samsung galaxy s2 where cpu has max 1200mhz. i set max cpu freq to 800mhz. with a good rom (hydrogenics f.e.) android keeps running smooth with 800mhz and battery lasts noticeable longer.
I agree that undervolting doesn't help so much.
Like in up post, best thing to save Your battery is to change cpu power. You can also use diffrent cpu govenor : good for battery are smartassv2 and power save. Just need to have rooted phone and download app, fx. Antutu CPU Master or Set CPU. U can also make your cpu speed profiles.

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!

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.

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.

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...

I am unable to get the Battery Charge Limit app to work on the TMOBILE variant of this device. The app allows you to set start/stop charging %, which helps prolong battery state.
Does anyone know where the control file is located? I tried searching in /sys/class/* but couldn't find anything like chg_enabled or something similiar.
For OP9Pro, the file is located here: /sys/class/oplus_chg/usb/chg_enable
For OPN200, I don't know

Writing 0 to this file disables charging and writing 1 enables charging. Note that the charging icon shows that the battery is charging if the device is plugged in even if the file has a 0, but checking with a battery app will show that charging is disabled.
I also noticed that the battery charge limit app doesn't work if you start the app when the battery is already above the maximum limit, it only works if you start the app with the battery at or above the limit you set in the app.
Also I didn't realize this but you can also use ACC and run

It seems @towardsdawn is spot on.
I configured Battery Charge Limit (you can find in Playstore) to use the charge control file located here:
Code:
/sys/class/oplus_chg/battery/mmi_charging_enable
And it seems to work. If the current battery % is HIGHER than the STOP CHARGE %, then the Battery Charge Limit application will say DISCHARGING but battery icons from homescreen and lockscreen will indicate it's charging. Even though battery icon from homescreen and lockscreen says it's charging, I did not see battery % increase.
If you charge the phone when it's BELOW the STOP CHARGE %, then the Battery Charge Limit application will say it's charging and the battery % will increase after some time until it reaches STOP CHARGE %.
Overall, it seems to work, it's just the battery charging status from Battery Charge Limit app and phone icons are not aligned. One thing I do notice is if current % is ABOVE the STOP CHARGE %, then it will stay at that % while plugged in.
just a heads up, make sure to disable battery saver as well as advanced battery optimizations when charging, these modes will kill the Battery Charge Limit app even if you have it set to "Don't optimize". had some issues getting it to work overnight and doing this worked for me.
a little ironic isn't it
looks like I spoke too soon, I fiddled around with the settings and still can't get it to work consistently. sometimes it works, sometimes it doesn't. I switched to ACCA and that works much better.

Battery Charge Limit is one of my fav apps.
I thought that you have to have root to use this app, no?
Could you provide a beginner's guide on your method? Noobs need it!

Here is a quick guide to using ACCA which I find to work much more consistently on the Nord N200 than Battery Charge Limit:
Unlock bootloader (see this thread, I used the debloat script. make sure to remove the line that gets rid of Gboard)
Root your phone with Magisk (see this thread)
Visit this website to download F-droid, then in the F-droid client download ACCA. ACCA will say installation failed for some reason, but it still works
Edit the default profile under the Profiles tab.
Under Capacity Control edit Charging switch.
Click Add Charging Switch.
Type in
Code:
/sys/class/oplus_chg/battery/mmi_charging_enable
for charging switch
Type in 1 for On value and 0 for Off value. Click ok.
Tap on the new charging switch. Click Test charging switch with the charger plugged in. It should popup saying the switch works, if it doesn't then you'll have to troubleshoot that.
Click Save.
Edit the other settings to what you want, then click the save icon in the top right.
Tap on the default profile to switch to it.
You may or may not need to do this, but under android battery settings I disabled battery optimization for ACCA and I also turned off all of the advanced optimization settings.
