Hey there,
I recently tried out the new Cyanogenmod 9.1 for Xperia Mini. I was impressed about some of the functions/improvements, especially the unbelievable bright display! Unfortunately the battery drain was not acceptable for me so I had to switch back to the standard ROM. So my question is has anybody an idea how we could increase the max brightness of the standard ROM? I mean it must be adjustable otherwise Cyanogenmod would not be able to give a much brighter display ... Any suggestions/ideas?
Thanks in advance!
Thorsten
Either use the ultrabrigthness mod from themes and apps section or download from playstore xperia autobrightness disable, then you can control screen brightness with toggles.
Btw, CM9 drains waaay less battery that stock, increasing screen brightness is what affects it the most..
Thanks man,
could you give me a link to the mod, couldnt find it ...
BtW, under cyanogenmod my battery drained over night like hell, so it obviously had nothing to do with the screen!
Thorsten
Here, push this file to system/etc directory with adb
https://dl.dropbox.com/u/44281412/hw_config.sh
Did you check the battery usage to see what drained the battery? CM cannot have higher battery consumption than stock, that's a fact, probably an app went haywire or something wasn't installed correctly.
will it have any significant battery drain if auto brighness is disabled??
Turning off auto brightness actually increases your battery since it's not using the light meter on your phone and constantly processing to change your brightness based on the light you are getting.
I got this phone last week. It's beautiful and very fast. But as expected, the battery is terrible.
The normal energy saver doesn't do much for me. And the extreme energy saver is not something I'd like to use on a daily basis. What does the normal energy saver do?
Normal energy saving mode
Stop background data, unless connected to WIFI
Dim screen, unless brightness is set to manual
I even noticed that the S Health services (constantly checking for motion pedometer) is still on in power saving mode.
There are a lot of options on this phone that are convenient, but I'm not sure which ones are having a non-negligible impact on the battery. Maybe we can combine our knowledge and come up with a list. We can each personally choose which ones we can live without, and which ones we want/need. I'll start with the ones I am thinking of:
Possible energy consuming functions
Touch Sensitivity: For when wearing gloves. Is this just the way software interpretes data, or does this in fact require more power?
Air View[link]: Is this just the way software interpretes data, or does this in fact require more power?
Smart stay: Uses front camera, which requires power. Is the camera always on, or only in browser?
Smart pause: Uses front camera, which requires power. Is this always active? Every video? Only Samsung video player? Youtube?
Smart scroll [link]: Uses front camera, which requires power. Only in stock browser? Or all apps?
S Health: I personally like the pedometer. Makes me walk a bit extra. Those pedometers you get for free with your groceries work forever on a penlite battery. But the one on the phone, does it have dedicated hardware? Or does it prevent the phone from sleeping, monitoring gyro sensors permanently?
Multi-window: Probably uses multiple cores. Can you just keep this mode active even if you use a single screen? Or does this mode permanently require more power?
3G: Switching to 2G always requires less power. Is this setting gone in the ALPHA?
Quick setting switches (toggles)
Half those options have a quick setting on the backside of the notification screen. But the other half does not. Which is annoying. Do the "hidden" features not matter as much for power? Is there a way to add these "hidden" features to the quick setting screen?
Discuss.
I would say that everything extra uses more power.
I always use power saving with limit cpu usage option, and haven't noticed a performance drop even if gaming. I also have disabled many samsung bloatware apps that i don't use (basically everything ). And I also use Greenify apps to stop those bloatware apps which can't be disabled.
If I had root, I would also remove "wake up" and "keep wake" from Google play services, which is currently my biggest battery draining app/service.
Hey guys, i've tested the "Restrict background data" and it works really GOOD!
More specific, my device is using 450mah (or at least, this is the reading im getting).
So with "No restriction for the back data" & logging to a 3G network (UMTS) im loosing: 1% / 2hrs
With restrictions ON & logging to a 2.5G (EDGE) im loosing: 1% / 3.5hrs !!!
Mind that this measurement is in IDLE state (screen off).
I believe that this "Restrict background data" option is also been used by the system,
when the user is activating the "emergency mode".
The Good:
- Snappiness and overall speed improvement: the Android N update made my S7 so much more snappy and responsive. The phone boots much quicker than it used to, apps install almost immediately after they finish downloading, and the keyboard is far more responsive and quick to register touches.
- Clean UI: The entire default theme on Android N is very clean and minimalistic, which I absolutely love.
- Battery Life: My phone drains much slower during active usage, and the new ultra low power mode is great. Not all is good in this department though, and I'll address the issues in the negatives.
- Customization: I think the customizability is great, and being able to control your DPI and resolution is much appreciated. Keyboard resizing works, though it doesn't get nearly small enough, and this is coming from someone who's 6"2 and has relatively large hands.
Automatic Reconnection: This has been both a positive and a negative for me, as I have Comcast at home and my phone used to switch to the open Xfinity WiFi hotspot at home instead of my private home WiFi. This fixed that issue, but now when I try to connect to a Xfinity WiFi hotspot it usually keeps giving me an "Automatic Reconnection is turned off", and won't let me connect for a good while.
The Bad:
- Battery Life: Standby time has absolutely gone to crap and I'm relatively sure sleep doesn't work.
- Bloatware-: Still has all of the unnecessary b.s. that Sprint S7's come with, and the voicemail still isn't possible to be disabled.
- Ultra Power Saving and DPI: Once changed/enabled, there is no "are you sure you want to keep these settings" prompt. I was outside when I was just messing around and enabled ultra power saving, and it was a struggle trying to disable it. Also, if you set your DPI to something which you are unable to read, there still isn't a "undo this?" prompt.
- App Incompatibility and Crashes: Two apps that I've run into that have issues with Android 7.0 are Pokémon Go and Opera VPN. Trying to enable Opera VPN under settings causes an automatic crash, and you can't expand its notification anymore.

X2, standby life is absolute garbage.
I am at 8 hrs 20 mins with 2 hrs SOT and only 41% left. It's not great, I'm not getting through the day.

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.

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...

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.
