I have a Mi2S and I'm running the latest stock ROM 4.4.23.
Ever since the 4.4.11 update I've had poor idle battery life.
Before that when I look at my battery usage, as long as I have good signal and the screen is off, the battery level graph is flat.
Now, almost always when my phone is idle, no matter what there is some heavy drain, it was approximately 25% over 12 hours.
I've tried all the MI2S updates since then and they are all having this issue. I have not installed any new apps or changed anything on my current ones.
Attached are some wakelock detector screenshots.
Sometimes 小米服務 has many wake alerts, but sometimes it does not. Weather app is disabled, and autosync is disabled too. Occasionally 小米服務 does not have many wake alerts but that doesn't seem to reduce idle power draw, and I think it had this many wakes before as well.
Also the 3h wakelock app is the music player; the idle drain happened when the music player was off.
Thanks for reading.
Bump...
So I spent a night in airplane mode, and voila! 3% drain over about 12 hours!
I'm still trying to figure out exactly what it is, but whenever I get the chance to I'm going to spend another night in airplane mode with wifi on.
Bump...
There is a nice little utility app called power tutor, which shows you exactly which app drains your device. Maybe the problem isn't rom related...
You can find it on the play store.
My google pixel is heating u der normal usage. Sometimes i just browse the net or watch some videos and the device gets heated up. I tried using greenify for killing the background processes but it didn't work. Sometimes the peak temperature rises upto 46°C. I also tried factory reset but looks like there was no use doing that. Also I've restricted the background data usage for many apps like the spotify beta and facebook. Under normal usage means using only one app the temperature reaches upto 36°C. Can't really understand what the problem is. Plz help.

Mine is usually in the 30's to 40's. Unless it is hot to the touch you are probably good.

Hello S8+ owners,
I'm planning to buy a brand new S8+ for 520$ which is a great deal. I own a Galaxy A9 Pro right now with 5000mah battery and 10hrs+ SOT, so battery life is very important for me.
I would like to know how much SOT do you guys think I can get with the S8+ using the following configuration:
Airplane mode always ON
Wifi Only
Cellular and Mobile data Off
Bluetooth Off
GPS and Location services Off
AutoSync Off
NFC Off
Bixby and Gear VR Disabled
Most of Google and Samsung background apps disabled
Greenify
Screen brightness 50% maximum
Black theme
CPU limited in power saving mode
Usage: Youtube 480p/720p mostly followed by occasional Whatsapp and Telegram reads, some light browsing and gaming. No camera, phone calls etc...
Thanks in advance for your feedbacks
if display resolution is HD+ then you will get 6-7h+ sot. I have S8+ and which is a year old now and i am getting 4-5h of sot with WQHD+ resolution, sync on, wifi on, mobile data on and everything else is off. I watch video in 1080p/2k.
I'm in HAVOC 2.0 OFFICIAL (Pie), but it will work with ANY custom rom. If you don't have the 1st option Smart Pixels in "Havoc Settings" ('cause you're using another Custom Rom) you can use the app: "Pixoff: Battery Saver" or similar...
Tutorial>>>>>
1 - Havoc Settings > Screen > Turn on Smart Pixels (62% of pixels disabled), and increase the brightness just a little to compensate.
2 - Use Greenify along with Greenify4Magisk module to freeze all GCM apps.. But you can just disable GCM and other stuff in "MyAndroidTools Pro" by yourself decreasing the need of freezing unnecessary apps... but you have to understand how android works or you will break your system (USE WITH CAUTION). (A 1 million dollar tip here: Disable things like "analytics", "gms", "GCM" (if you're not finding those words tick this icon "<-->" to expand the service names..
P.S.: Only play with Third Party apps... Don't mess with system apps!
3 - Use Naptime to make Doze mode work properly...
4 - Use AfWall+ to block all apps that don't use internet to leak data and hog your battery unnecessarily.
Extra Magisk modules I'm using:
- AdGuardDNS Adblocker (unofficial)
- Sysconfig Patcher (sp) helps to doze Google Play Services and system apps that hogs battery...
- Swap Torpedo -> to SPEED memory.. my old devices 1gb ram runs blazing fast with this and it works so f**cking good in Note 5 aswell..
* You can turn all animations off systemwide and your experience will be better IMHO
You can tell me if it worked or not.. But I'm getting 14hours of SCREEN ON TIME. :victory::laugh:
In the screenshot below I was in 7h39mins of Screen On Time with 50%... I'm just sharing all these stuff 'cause I finally manage to have a GREAT battery life. I used to mess with Amplify app once and didn't have so good experiences (Phone app missing calls and whatsapp doesn't showing notifications), but maybe someone else manage to get a better SOT than mine, using it properly..

Nice share
But usually the SOT is not the similar that you would get from 100 to 50 % battery and from 50 to 0 % battery. So it's not fair to say the SOT would double by sharing a screenshot of 100 to 50 % of usage.

If my usage will keep the same (4G always on: Whatsapp + Opera (facebook site mainly) + Instagram + editing photos on Snapseed + gallery), my estimated SOT is 12-14 hours.. I will post a new 100% test screenshot to prove you.
I mean, if the mAh consumption will keep the same over the same kind of usage, it's easy to trace a statistic number over it. Ok ok.. You want proof, just test it and tell me.. I had to plug the phone in PC to install some last apks.. But tonight was my final installs and tomorrow I will test it from 100% to almost 0%
Getting 11 hours of SOT on Revolution OS & Insigniux kernel and no tweaks at all. My usage consists of a lot of YouTube, reading books on the Kindle app, playing some games, and the usual social media (whatsapp, twitter, instagram). I also listen to a lot of music via bluetooth headset (about 5 hours per day). The phone lasts almost 2 days with such a usage. So yeah, I think this is more than enough for the average user such as myself, no need for all the hassle you posted above. It's really unnecessary.At this point, this is just turning to a "who has the best SOT" battle. Even 7/8 hours of SOT is something great for this device, while 800/1000$ flagships are struggling to push over 5 hours of SOT.
Thanks a lot for the time spent writing this. Would you have more information about the firmware and kernel you're using ?
First, to everyone that read OP, realize there are some inaccuracies. Sorry man.
Smart pixel settings and apps like PixOff only save battery for OLED displays. HAVOK OS is available for multiple devices and this feature is beneficial for devices with OLED displays, but does not make a difference to LCDs.
Our phone has an LCD display which cannot actually "turn off" a pixel . It consumes the same amount of battery no matter what color it displays. Display brightness makes the biggest difference in display battery consumption.
So by turning on "smart pixel" and increasing the brightness you are actually HURTING your battery life overall.
Secondly, you only tested from 100-50%. You will ALWAYS get vastly more battery life from the top 50% than the bottom, because batteries voltage does not drop linearly, it is chemical reaction that is actually quite hard to measure accurately.
There have been many times where I was "getting 14-15 hours SOT" in the top half, but then watch as your battery drops from 40-20 from only 1 hour of light use. I can almost promise you this guy won't actually get more than 11 hours by the time he hits 0.
Use it from 100-0 at least 10 times , showing 13-14 hours of SOT and I will actually believe you are on to something.
On MiUI 9.5.17.0 I already can achieve close to 14 hours SOT, but that is within 1 day 10 hours usage. Usually I get 11-13 hours only within 1+ day usage. On AOSP, specificly RR 6.2.0, I easily reach 4-5 hours SOT by 70% (which I usually charge it already), 15 hours if interpolated to 2 days usage. 10 hours SOT is almost guaranteed. Last test is 13 hours SOT within 2 days 2 hours. If you want to see what is the configuration and usage, just check the link. I prefer to state my configuration and usage during the test, to show any possible different variable.
1. SmartPixel AFAIK is useless in IPS LCD. I would prefer the full maximum resolution as not to downgrade my user experience
2. I don't use any greenify, simply use the battery optimization from android. I whitelist several apps : Automagic, GMD gesture, Whatsapp, MiXplorer. I never clean my recent/RAM. I remove the "nuke button" from the configuration.
4. I don't know starting from which version, but since Nougat 7.0+, we have the setting to restrict data usage for each app in the app info. I simply create a flow to automagically open the app info everytime I install new app and decide whether to restrict the internet usage or not.
For ads, I just use hosts based - adaway. I don't limit play services, just let it run normally. I don't tweak much on the RAM side, but I adjust the minfree on every reboot (using automagic) to the lower value than default by RR. This is to let more apps stay on RAM as long as possible.
I don't want to limit the phone's perfomance to ridiculous level. Smartphone are meant to be used. The battery used is the proof we enjoy technology. Of course if the drain is unusual and wasted, we have to troubleshoot and find the culprit, as I have done in the wifi deep sleep drain bug. But other than those exception, I want the full user experience I can get from my phone.
SOT Variation
SOT is kinda non standard way to measure the usage. It varies depends on the user habit and usage behaviour. I am using dual SIM with good signal in most of the time, no microsd. Common usage :
- idle with no internet : 0,3-0,4%/hour
- idle with wifi : 0,5%/hour
- idle with LTE : 0,6-0,7%/hour
- Screen on dim (brightness < 10%) : 5%/hour (outside of idle drain)
- screen on bright (brighntess > 80%) : 10%/hour (outside of idle drain)
- Play game : Depends on game, it can consume 8-20%/hour
Using basic math, If 25% are used for the idle with wifi, I can get 25% / 0,5%/hour = 50 hours usage. 75% for screen dimmed, I can get 75% / 5%/hour = 15 hours. So 15 hours SOT is possible within 2 days usage. This interpolate nicely with my 70% 4-5 hours SOT.
But If I use the phone outdoor and the brightness increase, I can only get half of that, 7,5 hours SOT only within the same 2 days. Or maybe 9 hours SOT within 20 hours usage. If I have bad signal, it will reduce even further, 5-6 hours SOT only. Playing heavy game (PUBG) usually reduce the SOT by half too. So playing PUBG in dimmed brightness will consume 10%/hour and in brighter, 20%/hour. Increasing/decreasing the graphic also modify the drain per hour. Usually playing heavy game result in max 5-7 hours SOT only. But sometimes I can still get projected SOT around 10 hours, depends on what game I play and how many hours I played it.
Taking it to the extreme, we can spare 10% for the wifi idle, giving 20 hours usage and 90% for screen, giving 18 hours SOT. Which mean we can achieve 18 hours SOT within 20 hours usage. I am quite addicted to the phone. I use it for browsing, learning language, reading ebook, watching video, designing flow in automagic, usually without any gaming. But even then, it is very difficult to use the phone straight for 18 hours within those 20 hours (without gaming).
It is very difficult for me in usual daily activity to test the battery life till 1%. I usually have to plugged the phone for screen mirroring or transfer data. It will skew the battery usage then. I also usually just charge the phone at around 60-70, sometimes higher, sometimes lower.
At this kind of battery life and perfomance (SD636), I am very happy with current usage without the need to tweak so much again. Just use your phone as usual and only troubleshoot the battery life if something drain too much without doing anything useful. Enjoy your smartphone.
