Hello there. Ok so I have this weird issue my hd2 is eating up battery for breakfast. It's weird cause on standby it's incredibly resourceful and only uses around 4% overnight. On any kind of usage, it literally starts to drain before my eyes!
I've seen some people set the power management off in advanced config, just wanted to ask where do I get that. And in bsb tweaks I set the option to enable power management, is that a setting I could go into somewhere or I just set that on and off?
I think everyone has issues till we find the best ROM/RADIO solution...depending on our usage/country! Today my battery drained 30% overnight...and it was fully charged when i go to bed...(7h of sleep)! But since i woke up...(2h...it only consumed 2%!)
And now as i write this i'm having a SOD (Sleep of Death) @£§€[#"$!!! :/ I'm really tired of this sh...! I think is a problem related to the latest builds rather than a phone problem, nevertheless it freaks me out!!!
Check the brightness...i have mine at 30% which is enough for most situations!...
(TIP: Create a shortcut to automatically rise the brightness to 100% when you are under direct sun, otherwise you'll have trouble to read the screen!)
...this is what saves most juice...then you could try and look for tips to maintain Activesync shutdown when not in use...always close your apps....and (IMPORTANT) disable automatic updates (or at least set the update time to 2h or more), after that check for programs to disable/close idle internet connection (like: WMLongLife, Bandswitch v2.9)
Hope this helps!
Shwanz..you need another zimage for your build,changed mine to the 4/05/2010 havent had any probs,but you might have to find one that works for yours.
Peace
My English might be poor, hopefully this thread help. I have flashed stock ICS in my tab baseband XXLQ8. After fully recharged my battery, I found that the performance was not tolerable since in HC 3.2, it only drains 2-3% battery life per 24 hrs in a sleep mode. Unlike HC 3.2, ICS 4.0.4 (baseband XXLQ8, some addressed as Italian stock ROM) drains 1-2% per hour in sleep mode. My battery life dropped 7% in 5 hours without any usage (off screen).
Later on I installed CPU SPY and BetterBatteryStats suggested by some of the posts here. Having the same problem, my tab could barely get into the Deep Sleep state when it was in sleep mode. Instead Deep Sleep, it still works under 216 MHz.
Somebody here suggested it was the Push Service in Samsung App, Google+ or something. Some even found that it was the GSM problem. With the sim card slotted in, the problem gone. However we are pretty sure the effect of the problem is battery drainage in sleep mode. We found that there is a kernel wakelock called l3_hsic all the while running in background that prevents the tab from going into Deep Sleep.
There are several possibilities causing this to happen. Apps creating wakelock maybe, some suggested Google+ with the sync or upload function enable; hey, wait! I don’t have a Google + account signed in, could that still be the problem? Some say Samsung App Push Service causes it to happen, so I just give it a try. Launch the Samsung App, go to the Settings and disable the Push Service. Put the tab to sleep for an hour and check back. Battery drainage still occurs since it dropped 2% for an hour. What a disappointment. But wait, this time I get into the tab Settings>Application>All and find the Samsung Push Service. Checked there were permissions such as creating wakelock and prevent tablet from sleeping. Tap on it and uninstall the app. Put my tablet into sleep again.
After 3 hours, turn on the tab and check back with the battery stats. CPU SPY shows that my tab could get into Deep Sleep state. My battery life did not even drop a single percent. Today is my third day from the last charge. Thanks god, problem solved.
HIT THANKS Button if this helped you.
It doesn't work for me. Still looking
and for l2_hsic what could be the solution? i`ve searched on xda and google but i didn`t find any reliable solution. Any advice?

Is that the "battery drains while on airplane mode" issue? I have it too :crying:
it doesn't work for me bro..
for me, i noticed that google maps (auto update on my place, that friends can see where i am) Since I enable auto location my place, i get no deel sleep, when i have disable it, i have 100% deepsleep
I disabled Maps to fix my battery drainage issue. If I need to use maps I just enable it.
Sent from my DROID RAZR using xda premium
The solution to the l2_hsic is to insert a uSIM.
Nevertheless the deep sleep problem will remain. Sorry!
hello,
can we flash another kernel ?
I have the same issue with my galaxy tab 10.1 running Stock ICS 4.04. Something is interrupting deep sleep mode and the battery consuption is 2% per hour in standby mode.
After rebooting it seems to be OK but later and i dont know when/how/why... stops entering deep sleep. I think this problem needs a revision by Samsung but i am sure that they have forgotten us.
I've seen a firmware update on some other thread, for our tablets... but it seems we're not getting it OTA
Another Tips for slove it

Hi guys,
I have read countless threads on battery life & wake locks on XDA, Reddit, etc. Trying to find a solution to what I still find the Achilles heel of android, wake locks.
I am running stock on MHC19Q build
Adaptive brightness off
Wifi scanning off
Bluetooth scanning off
Battery Optimization on all apps except for DMService and Google Play Services
Some days I will go 2-3 hours with 30 minutes SOT and my battery only drops 10%. Doze works as it should. I will get through a full day at about 4 hours SOT (6am to 10pm).
On other days (like today) I am unplugged for 3 hours at 80% with 10 min SOT. I have rebooted the device 3 times since unplugging it and my wake locks are still occurring. My signal is perfect green through and through. Bluetooth off and connected to wifi.
I find the issue comes and goes. Some days the phone will start out great, only to have wake locks start occurring mid day. I think Android OS appears to be the issue.
Anyone else encountering wake locks that come and go?
Any help would be greatly appreciated! :victory:

Absolutely same situation. No new application in monthes.
Google play services is usually the battery waster I found when moving around, I tend to place phone down when I can to save juice but you really need to identify your wakelocks first. I'm rooted and use bbs.
Disabling location may help, if rooted and using xposed, amplify may help too.
Google play services get updated when it's pushed out, sometimes it has bugs.
Maybe if you haven't updated any of your apps for months, then possibly one may need updating now.
So I've been trying to find a solution to this 5% battery screen dim/camera flash dilemma for some time now when trying to calibrate my zerolemon 100000mah battery on my note 4. I've read many forums and no one seemed to have an answer. I stumbled upon the answer today and felt I needed to share with everyone.
Go to setting/developers options and click "stay awake".
That's it. That freaking simple.
My phone is currently at 1% and my screen is bright and I have no functionality loss whatsoever.
Hope this helps someone.

Turns out it wasn't the "stay awake" but the fact that I was using UC Browser, had just watched a video with full brightness (using the left side screen slide (on screen) ) and when I exited the app the screen stayed bright.
I've not seen any other solution to this issue. But this actually works. It was a coincidence that made me believe it was the "stay awake" button. But now I have that turned off and still have full display brightness at 1%.
It's out now with both factory images and OTAs

FlashKernel v2.43 + Magisk 16.4 working fine
Magisk is still working for me, still passing SafetyNet.
Not possible to sideload the OTA file via TWRP, correct?

Not sure. I installed it by unpacking the factory image and removing the -w from the flash-all script
I always forget about that.
got it yesterday through ota, till now it runs fine. No performance difference so far (no unlock timeout luckily, although the problem was with Oreo June update, you'll never know if it travels to P).
Think I found 2 differences so far. The first is pretty cool, on the AOD you see now the weather under the time, next to the date, the weather icon is in color, looks really nice! The battery indicator on the AOD looks the same, bit too small in my opinion, little doubt if the font size is +1... but i don't think so.
The second thing that i found is that when you search in the settings, the result isn't flashing anymore but just a solid color that indicates the option you where searchinig for.
Adaptive Battery is enabled automatic after update, i turned it off before, because it just used more battery in standby when i turned it on. In the first couple of hours, it looks like it now works when enabled. After a couple of days it should be clear if it makes the standby drain a little less.
Couple of dutch apps work now, those crashed before when launching them. NOS, Ziggo GO are working fine now. The ABN Wallet app (sort of google pay replacement) doesn't crash on launch, but i need a reader to enable this wallet, and that reader is at home, i'm at work now
I did not factory reset the phone because it is a small update.
I'm noticing terrible battery drain. For instance unplugged phone when fully charged at around 3:30am by 8:30am battery was at 56%. Before the update only 5-6% would be discharged during that time. Battery stats show no app usage and claims everything is fine so I have no idea of the cause.

True, but it's good to let people know the extent of the problem, known or not. Personally I would not have updated if I knew the issue was this extreme. Point taken about it being a known issue though. :good:

Until now (half day use) I don't have much battery difference between dp2 and dp3. Try to turn adjustable battery management off. In dp2 my phone had less drain with the feature off. This half a day I have turned it on and testing if the drain better or worse. But the drain you're describing isn't normal. Have you tried to factory reset? With Google backup it isn't much of a hassle in my opinion.

I get what you're saying. Just didn't know if you knew about the known issue so I wanted to make you (and others) aware that there are known bug & where to find that documentation. We're all so excited to try the latest/greatest that we never look at what might be wrong.
Also my anecdotal battery usage has been decent since I flashed. Obviously today is my first full day of usage but so far it hasn't been too bad. I unplugged ~6:45am, made a 15min phone call, and it's been sitting on my desk getting minimal usage & I'm at 95% and it's currently 10am.

It's pretty weird. I installed it yesterday afternoon and noticed very little difference, it was just like suddenly overnight despite no app updates or notifications the battery just drained. I turned off the adjustable battery management a couple hours ago and I'm already seeing a difference. I'm going to hold off on the factory reset until I give it another day to see if that does the trick. Thanks for your help!
Hey guys, I keep on getting the "an error has occurred" message when attempting to do the OTA. I know I can probably just side load the factory image later on tonight but is anyone else having this issue? I have a custom kernel installed so maybe that is causing the problem? Although, that said; the custom kernel didn't bother it going from Oreo to DP2.
Just finished installing pp3, along with root and flash kernel 2.43 (latest).
Pin stop being accepted after a couple of reboots, and didn't work not TWRP as well.
Once rebooted again started working
Keyboard didn't work at first just typing this post.
Hope it has something to do with everything just settling down.
Today I too experienced a noticeably faster battery drain. As alluded to above (from release notes) it might be attributed to the new screen settings. I'll see how it does but I've turned off adaptive display and set my static brightness setting to 40%...in the past I used to use 30% and it was plenty bright but not under the new system. Has anyone come up with a recommended brightness on the new slider that is both clean/legible and battery friendly?

Try turning off Adaptive Battery in the battery settings, it got turned on by default in dp3. After I did that yesterday my battery drain stopped.
So, when I try to install magisk and patch my boot img via magisk manager, my installation keeps failing. It says it's unable to extract the magisk zip file. Anyone else having this problem?

I just turned it off and will see if there is any difference. I suspect that it may take a little while for the adaptive battery feature to "learn" so that might be the issue. If so, I'm hoping that Google or a thorough reviewer will put out some guidance on how it works and how long a user would need to be patient before seeing any advantage to using it.
A day later and adaptive battery is still on and do not experience the drain you guys experience. With adaptive on the phone has a better battery life than with dp2 and oreo. I travel for work witch has a severe impact on the battery. Normally I have a screen on time of 1 to 1,5 hour after work when the phone reaches 50%. Today it was about 2 hours and 20 to 30 minutes (not checked out at 50%). But I think it's better then before. Hope it will stay this way. Hoping a little more the 'ROM' will settle more and adaptive battery getting better. Will try to report this weekend or next week.
The only annoying thing on this update I found, when you press menu to see your opened apps, it sometimes put it at the side with the "clear all" already displayed.
An occurence which occur randomly: I open whatsapp, I go out to home screen, I press menu to show the opened apps.
Whatsapp is not in the middle, instead it is on the right side, with "clear all" button on the left side, other times it works normally on the middle.
The problem that occurs afterwards is that if I try to clear the application by swiping up, it is stuck in the menu mode, so I have to scroll up to get my list of applications, then scroll down to revert to home screen.
As I mention again, it seems to be random occurence, and I don't know if it's a bug or it's a problem with sensitivity.
