Hi,
I'm having the following problem:
Short story:
From time to time something triggers battery drain in deep sleep on my Xperia Go. Usually my phone works as it should (battery drain over night is just a few %), but suddenly something starts to drain the battery and only reboot can stop it. I haven't figured out any pattern at which the drain starts, sometimes it works fine for weeks but sometimes it starts just a few hours after a reboot.
More details:
The phone is Xperia Go with the latest stock FW (.100). It is rooted but has locked bootloader. I have no bloatware installed, no Facebook, no Viber, no Whatsup, basically nothing in background and both WiFi and mobile data turned off (even location services turned off). I'm not using neither Sony's Stamina mode nor Low battery mode. I've verified that the system is really in deep sleep during the night by running script like this in terminal (https://play.google.com/store/apps/details?id=jackpal.androidterm&hl=en):
i=0
while true; do (( i++ )); echo $i; sleep 1; done

It is simply counting seconds while awake. There are only a few lines printed in background during the night so I'm nearly sure that the main CPU is sleeping most of the time. So I can think of 2 other suspects. First would be the radio (GSM module) as that is the only part that is running even in deep sleep. Second would be the Mali GPU as I don't know how to verify if it is really sleeping. Both are also restarted with system reboot which temporarily solves the problem (sometimes even for weeks if I'm lucky).
Anyone can confirm such behavior?
Any idea how to restart radio or GPU only without system reboot?
Any idea how to check whether GPU really sleeps when screen is turned off?
Any other ideas?

I keep it on sleep mode and the next day may battery is fully spended can anyway tell me why or how to prevent this?
Thats a known problem (just in the newest firmware)
I would install Urukdroid
No it is not.
in 100% of the cases an App is holding the Archos from going into deep sleep.
Just check that wifi can sleep, no Sync is on, mail, facebook or other inet apps are not holding connections.
I usually just keep it in Airplane mode, and only turn on the WiFi when I need it. This has helped with the power use problem.
I tried setting it to deep sleep, but I found that it would invariably crash when asleep (or when waking up--I don't know which).
I just turn my wifi off and put mine into Deep Sleep. I can leave it for days and the battery only drains a few percent (usually ~1-3% per day).
Some app must be waking your device, and causing the drain.
Installing UrukDroid is not the answer to all problems. I know some people here seem to think so, but there are bugs there too.
I'm not trying to knock UrukDroid at all, or the work that Sauron has done, but just switching your OS is not the best answer.
Hallo Iv got an Asus Padfone and have an annoying bug when my screen goos of and my phone enters stand-by all data connections are served wifi and mobile.
I can still revive calls but my whatsapp and other programs don't receive updates unless i unlock the phone.
This is very annoying since I have missed a lot of conservation some are 10 hours old.
I have done some research and I'm not sure whats cosing it but I think its something with the deep sleep mode of the processor thud doesn't wake properly.
when I check my cpu status I can see my processor is 96% of the time off line 2% active at 384MHz and 2% at other speeds.
Sow I think my phone cant wake when it needs to.
I have done a factory reset several times and tried diffident firmwares.
I also have tried software like wake lock but the sleep mode just overrides it.
Do you gays have any idea how to solve it like modifying the build.prop ore kernel?
Thanks
*note: I'm not using any power saving apps or settings
Hi all,
Recently, my fonepad battery suddenly drain 30-40% faster. In other words, it completely drain in 13 hours without any talk time. This happened after my house have a sudden blackout during phone charging which at that point is 85%. I had tried to reset the phone (via power + volume up button) now still fail.. Attached are the screenshot from battery widget, settings and wakelock detector.. Any idea ??

Use BetterBatteryStats to determine which process keeps your device awaken. BBS will give you more information than Wakelock Detector.
The main culprit for you seems to be the alarm_rtc wakelock, which handles alarms (when an application or process checks periodically on something). So maybe your device is trying to sync something but fails to do so and thus keeping your device awake. You could try to disable all apps that sync data one by one.
So from the last couple of days i am noticing that phone is continue heating & draining batterya fter removing from the charge, first i thought it's due to continuous usage of YouTube & Chrome app so i uninstall them to check weather problem exist also what i have noticed that battery draining at night when phone is sleep, then i downloaded Accubattery app so i can track the battery hogging application, what i found was after charging phone is refusing to going into deep sleep, also if i restart my phone it works fine only until next charge & again i have to restart it, Can someone confirm what's the problem & weather it's certain application bug or something wrong with the device!
I tested this with different watches and different apps and the result is always the same - there are almost constant Bluetooth wakelocks (BetterBatteryStats reports over 50%) and hence battery drain - but only when the watches are NOT connected. When the watches are connected - everything is fine!
I am running rooted Android 10 and tried to manually put the smartwatch apps in the Sleeping apps and Deep sleeping apps (Device care > Battery > App power management) but the result was absolutely the same. Only when I uninstall the apps, the Bluetooth wakelocks and battery drain stop.
This is driving me mad because I have to keep the watched turned on at all times, because otherwise will face battery drain. Has anyone had the same problem? Any idea of how to solve it will be much appreciated.
Can you not simply set it to go to sleep when not in use? (Through >device manager >battery)
I know it's possible because I had the same problem with my girls phone a while back, just can't remember how exactly I fixed it, but it turned out to be pretty simple...
Thank you but I did this as I have described and it desn't help.
