I know there are a lot of threads talking about battery life but I've made this one to look at trying to find the best roms, radios and tweaks to get the most out of the diamond.
Can anyone with a battery life of over 10 hours on heavy use (regular text and email use, maybe an hour of music and an hour of web surfing / gps and atleast half an hour of calls a day) please give any details of rom, radio, tweaks youve applied.
That way we can try and find the best solution for optimising battery life .
Im currently getting 10-12 hours of runtime with duttys 2.6 rc1, radio 1.00.25.08 and no tweaks applied. Screen brightness set to auto. Bluetooth and wifi off, wired headset plugged in for about 1.5hours of music.
Thanks in advance to everyone that helps by writing down their info!
If you let the device running without going to suspend mode, the battery would last for about 4 to 5 hours. That how many hours the battery would last and you can't do anything much with it, unless you buy the extended battery which would last about 7 to 8 hours.
By going to suspend mode (pressing the power button), the battery is put into suspend mode where it uses the minimum power which would last for about a week (if you never wake the device up after a full recharge).
So, my point here is, it doesn't matter what you do, you could only use your device for 4 to 5 hours (usage time, not including suspend mode) and believe me, you can't possibly tell how long you've actually used the device unless you use software to tell you exactly how long you have used the device (not including suspend mode) as sometimes you thought you're listening to music for 20 minutes but actually you've been listening to music for 30 minutes, or you've waked up the device from time to time to send/receive sms which could have totalled up to 1 hour, where you aren't aware of.
I hope some one could help me ...
My galaxy I9305 have for 2 or 3 weeks now... leaked battery very fast
When i pull out the phone from charger at 06.00 AM (its at 100%)
when its 08.30 AM its about 80%
In that period is both wifi and data disabled..also gps and bluetooth
But the strange thing is .. from 08.30 AM to 03.00 PM
it only use about 20%
In that period i use my phone in my lunchbreak ,surfing facebook, mails etc..
and all the time is data activated..
So now i wonder.. is there a way i can get a normaly battery leak from in 8 hours ( about 25%)
Is the battery stats ****ed up.. or what could it be..
Im using a sentinel 6.0 Kit-Kat rom
I really hope that someone could help me...
BTW... all my apps is the same ... over 3 the last 3 weeks..

The first period i though is strange, case with everything disabled and if you are not using the phone, it should has decreased at max 4% in 2 hours (wich already is too much for me). I can't compare with mine cause i'm on stock unbloated and agni kernel.
The second period must be normal, if you said you were surfing through facebook, mails.. I assume you used your phone at least 3 hours with screen on. Screen kills most of the battery and thats normal. And you said you was on mobile data.. mobile data consumes more battery than wifi, so use wifi when available.
The best for you to help us help u would be take some screenshots of the battery usage at some times, because we don't have sure how many time the screen was on from 6:00 AM to 3:00 PM. Make another test taking some screenshots of battery usage in details so someone here can help you bro
ok many thx.. i will take some screenshot...
I suggest a read of this: http://forum.xda-developers.com/showthread.php?t=2551846
I know it's lengthy and most might not apply but it is what improved my battery consumption.

you're going through the battery at an abnormal rate especially if your wifi and mobile data are off... What type of battery do you have is it stock or something else?

Battery issue continued
i have now uninstalled a few program.. that was using much battery..
The one > mcafee Mobile security.... using very much ..
now its uninstalled... restarted mobile... installed again...
Now i got much more battery time...
So i think that program was ****ed up somehow...
but i will test for a few days, just to be sure...

Not sure this is the right category to post but it's a topic that probably could touch on different sections.
Main point is that my battery on the Note8 is not what I'd like it to be.
I have had used in recent times the Huawei Mate 10 Pro and was impressed by the battery life there. Using the same exact setup (apps and same number of accounts in push) I was able to get over 5-6 hours of screen-on time. Watching 30mins of YouTube would suck less than 10%, while the Note8 takes around 18-20% for doing the same. My avg screen-on time on the note8 is between 3-4h with the same type of usage and apps.
So, is there a way to copy and have in place the same sort of battery optimization that the huawei uses so my note8 lasts more?
There are 4 million battery threads out there. If that doesn't help, buy a Mate 10.

You better search about batt optimizations for your note 8 variant, there are many threads regarding this, the note is unique among all devices out there, and unfortunately, the batt should have been larger in my opinion, my note 8 eats some 18%~20% per hour using youtube, but this is due to the way I have configured services, connections, sync, apps disabled, and apps I have always running in background and such, there is no recipe or magical set up, you have to try and observe, choosing what looks better for your particular tastes and needs, ulyimately, if batt life is such a big deal, surpassing the benefits of a note series device, sincerely, you would better have chosen some other device with a larger batt,there are plenty of those with 4000 mah or more, but honestly, I would never touch any of them

I had the same problem before, until I did a factory reset and now I reborn to be happy with my note8.
Some tips:
- brightness over 50% will kill your battery
- aod uses 1% per hour when it's activated
- don't hesitate to disable full resolution because the saved battery is around 10 minutes. Sound optimization also uses 0%
- try to turn off bluetooth
- optimize battery usage and monitor for apps in settings
- don't install apps like grenify and just disable Google and Facebook's apps. If you disable Samsung ones you could mess your battery life.
- try to use all stock, example: use stock file manager and not es strong explorer....
I use full performance mode all day but I don't give the brightness bonus, with GPS,wifi and 3g on all day too, also iris recognition and fingerprint. The battery should allow to you play with heavy games around 3:30-4 hours.
Regards

I'm assuming you do not realize that the Mate 10 Pro has a battery almost 1000mah more than the Note 8. ?

That Huawei has a bigger battery, different type panel, etc. Hard to expect same battery life with different hardware. You can turn off unnecessary settings/services/syncing, use dark wallpaper, watch brightness levels, factor in your signal strength, etc. See battery optimization threads or google for more.

Hi everyone,
I received my phone a week ago.
After first boot it updated to miui 11.
I noticed a day later that the battery is getting empty fast. Much faster than my old redmi 4x.
I figured out that the CPU usage is never under 19% @ 595mhz
I testet that with different apps that show the CPU usage.
In case of that the phone also never get into deepsleep and the battery drains and drains...
Is here someone who can help me please?!

Sounds great! But how can i go back to 10?
First put phone into fastboot mode, then check antirool feature with command fastboot getvar anti if you have
anti: 1 it's all good, after that you need to download from Miui page proper recovery rom, put zip on your phone storage and then flash via Miui system update in settings. Don't flash wrong rom it can hard brick device if you have locked bootloader, also remove password for screen, fingerprints, all accounts, miui cloud

Thanks for that! I´ve downgraded to MIUI 10. But the CPU usage is still never under 19% . If the battery now will drain not as fast as before i will see., but i think it will be near the same.
Maybe you can do me a favor and check with the app " CPU / GPU meter & Notification " if your CPU is going under 19% usage. Maybe it is a issue with this kind of apps....
Probably apps have problem with readings..
I think below 19% when device in deep sleep or battery saving mode. Dont know about that app, maybe just reading in relatime. There is a case when i like your case, at first day using miui 11 stable eu, i can get 2days with 6h sot, most of it using wifi. Then i setup my phone completely. On next day, the battery getting drain fast, and it cant last for 1 day, and just 5h sot. Next i check battery usage, and whatsapp at the top rank. And i unlocking every task. The next day my battery back to normal. And when im writing this post, my battery have 85%, 2h sot, and 7h ago since last charge.
Miui 10 with airplane mode enabled
Since I upgraded to MIUI 11 the battery drains fast
not much draining for me but never go deep sleep, most used frequency is 576 mhz
Hi everyone,
I have the same sad issue.... changed from a 3 years old Redmi Note 4 to a 9 lite.
Battery life with my old Note 4 (same 4000mah) was twice the battery life on my 9 lite, after 3 years!!
I disabled everything in 9 lite, NFC, wifi, bluetooth, background and startup apps, animations, notifications, Gplay updates, face unlocking, always on display, enabled dark theme etc etc....
Same battery drain, 12-13% Android System usage on battery stats.
I hope it will be fixed on a newer MIUI update, but it is very irritating to have to charge a new phone every day, when on an older you had a double battery life.
Please update us in case we'll found a workaround....
Just a question.... How do you monitor CPU usage? I see the setting inside developer options has been removed.....
Same here. Tried many things. Looks like "Settings -> Battery and performance -> Battery saver" solved problem for me. Used to drain ~30% over night while idle, now ~7% in same case.
I suppose battery saving tries to shutdown functions I already disabled...
I tried to leave a feedback to Xiaomi.
Also I created android commands local file dump with code *#*#284#*#* and trying to investigate by myself...
I tried modify modify some settings and uninstall or disable some not used apps before. It made almost any difference.
Previously I used Samsung smartphone. With similar settings I had great battery life. It seems mi 9 lite just cannot sleep/deep sleep without Battery saver turned on. I did not notice any difference in performance, user experience or notification frequency while this setting is on, and it seems it works in different way compared to Samsung implementation. Just give it a try.
May be I'm out ; when I sleep if my screen is " up " I lost 25- 30 % of battery : ( when my screen is "return" 4 or 5 % : )

With my 3 years old (after 3 years...) Xiaomi Redmi Note 4, I assure you, battery life was at least triple of my new 9 lite...

Interesting.... I'll try....
I find it crazy how this phones loses 7-10% overnight while my RN5 lost maybe 2. I work and live in area with bad 4G but decent 3G signal. I try to force 3G when I can.
I just switched on battery saver to see if it helps my standby drain at all.
I'm currently at 1.5 days off the charger, with 37% battery left after 4 hours of screen time. I am a fairly light user and just browse Reddit, XDA, text, hangouts, and 2 email accounts. Reminds me of my Nexus 5 lol. So terrible considering I do so many things to try to squeeze as much battery life as I can.
Maybe my Galaxy Watch being constantly connected has something to do with it.
Top 4 battery users are :
Android system 20%
Phone Idle 12.7%
Cell standby 12.5%
Screen 9.8%

Have you tried a GSI? Does anything stop working, like finger print reader, etc?
Inserting code ##4636#*#* and accessing networks menu, I found that in both SIM1 and SIM2 is set as default (LTE/TD-SCDMA/UMTS if you have 2 SIM and you use Dual 4G, LTE/TD-SCDMA/UMTS on SIM1 and TD-SCDMA/UMTS if you have 2 SIM and don't you use Dual 4G as default), the chinese network TD-SCDMA (before or after LTE network)
Probably this cause waste of time, battery loss and an higher sar level, mostly when LTE network coverage is not at its best.
Unfortunately this setting can be modified inside this menu (setting for example LTE/WCDMA), but this is lot when you restart the phone.
My firmware version is PFCEUXM european Rom.
I wish this TD-SCDMA chinese network will be definitively removed in next rom upgrade!!!
Hello, I had p30pro and was perfectly satisfied with it but from curiousity changed it for oneplus 7 pro and then galaxy note 10+, wasn't satisfied with those devices because of worse battery life than p30pro, I had 8-10h screen on time with p30pro and ~5h with one plus 7 pro and galaxy note 10+. (gsmarena endurance rating is not correct, p30pro according to them has 100h endurance rating and galaxy note10+ has 107h, so I expected battery life to be pretty much the same but its far from that )
because of magnificent battery life on p30pro i changed back to p30pro, but this is second unit I got and battery life is not like on the first one. first one was 1 year old 8/128, current one is 8/256 3 months old and I have like 5-6 hours screen on time with new one which does not satisfy me, battery life is primary reason i got back on p30pro.
usage is the same, same applications installed as far as i am aware
I have screenshot from first p30pro with 8hours screen on time and 25% battery left, it was so great that I had to save it :laugh: and battery life was contant like that
Other pictures attached is from current device, 3h31min screen on time with 38% battery left, so by the time it drops to 25% like screenshot from first p30pro it would be like 4h30min screen on time, big difference. battery life is constant like that
any tips, solutions, suggestions, thoughts?
-i did wipe the cache in recovery
-i tried dark mode
-no app seem to be draining the battery
solutions that i am thinking about:
-wait for 10.1 update for my device and see if there is any changes
-sell this one and get third p30pro (really dont want to do that, I will lose money and time and would be furious if i dont get good battery like on first device )
-factory reset (really dont want to do that, I will lose half a day again customizing and installing everything)
is integrated battery info correct, could there be something /an app that drains the battery but is not showing correctly in battery usage?
FAULTY UNIT?
There must be somethnig draining battery , either delete one by one apk and see if it improved, then you will know which apk was trouble, or hard reset and manually reinstall all apks, do not use backup as faulty apk will do same harm.
Second phone was new or second hand? If second hand you should do hard reset first.., tip for future..
one thing I noticed on screenshot from first device is that I was using only one sim card back then, I turned off second one now and will see if battery improves, altough in Screen On Time thread I see people have 8-10 screen on time regularly with two mobile signals.
"there must be something draining the battery..." can there be anything like that but not showing in battery usage correctly? because everyhing in battery usage seems fine.
both phones was second hand and I did reset them, but from menu, dont know if there is any difference in reseting from recovery?
1. EMUI 10.1 have same battery in some cases may be worse battery than EMU 10
2. Why sell phone if this one is good just need find what eat battery
3. Factory reset thats in many cases fix drain problem but if you wont do that why you not do backup first than make factory reset
Solution
1. Try put all apps in sleep mode settings ---> battery ---> startup apps (there enable sleep mode on all apps only leave apps from where you want get notifications)
2. Dark mode i recommend you use it any time its not save your battery too much but it can help to save battery
3. Use Huawei optimizer app to clean junks and optimize phone
4. Disable synchronizatios
5. Disable GPS, NFC, Bluetooth if you not use it (if you use any navigation than just use GPS when you not need it)
6. I see your Google Chrome use too much battery use instead Kiwi Browser
7. Same about Instagram use light version of instagram or try InstaMod app its better for me
8. Your screen display use 24+ % battery try lower light i have set on AUTO BRIGHTNESS (Tips in settings display set lower resolution)
9. Cell standby try disable mobile data when you not need and btw try put sim in another slot
10. Disable or Uninstall all apps from Google i have disabled Google Movies, Google Music, Google Drive and mayn other apps just disable all apps which you not use
11. I see you are on stock launcher you can try Nova Launcher or Evie Launcher or Microsoft Launcher....(Tips Evie Launcher is one of the lighweight launcher and build for performance/battery i now use Microsoft Launcher which is same as Evie but with little more functions
If you need any info just ask
so I disabled second sim card yesterday and this is result I have now, much better! 1h16min screen on time with 86% battery, which corresponds with about 8h screen on time :good:
can't believe another sim card has so much impact on battery life. my signal is full!
in next few days I will try only 3g or 2g enabled instead of 4g for second sim card to see if that makes a difference.
5 hours & 40% still left, always using data connection. Mainly browsing and watching videos.

I think I found your cause of drain. Go to settings, apps, apps, on the top right click on show system apps, then check for hms core. Click that, then on the top right you will se a gear. Click on the gear and carefully untick everything that has to do with data sharing, analytics etc. Check your battery again and let me know mate ??
