help required! battery draining drastically! save my z1 - Xperia Z1 Q&A, Help & Troubleshooting

Can someone help me figure out where and why my battery is draining! I have tried everything yet can't figure out a way to reduce the drains. There is no change in estimated battery time on activating stamina mode and then stamina mode along with low power mode. Right now,against 64% battery it says 15 hours remaining. This is very bad. On deactivating both battery saving modes,i have only 5 hours of back up. What to do! I have attached battery usage statistics if that helps.

If you have just updated to the KK version wait a day or 2 for the battery calibration that can cause that.
Most of times it's due to 3rd app not updated to the KK version that ruins the battery when that try to access to the SDCard.
I've had exactly same problem and i thank really much gregbradley for the solution. I've revoked the SDCard write permissions (it's this case by default) i can't write to it but i haven't anymore the battery drain and overheating problem.
So if you have used the fix to have writing permission to your SDCard then you have the solution.

Looks pretty good

Did you charge in between? 1 day plus and still 63% is very good, if you have not charged in between. Regarding the prediction about 15 hours for 63%, take it with a pinch of salt. Check the actuals and see if it really is 15 hrs. Then we can check what is draining the battery. I think if you use it the same way, I see no reason why it should not come for another day..Currently there seems to be no reason for any alarm.
Just my opinion.

I did charge in between hence my problem. One more thing i noticed was that on switching off stamina mode and switching on low battery mode at the same 63% shows just 4 hours of battery backup. Whats up with that! Thinking about factory reset. Any suggestions?

Display + Battery level

Hello,
I recently got my nexus, and rooted only two days after receiving it. I installed cyanogen's latest. I am getting low battery; in only 5 or so minutes, the percentage goes down by at least 2 percent (while using). I looked to see what may have been draining the battery, and found that the display alone was using 62% to 75% of my battery. I tried undervolting, but the display seemed to still be in the same draining range...
Is this a hardware related problem, or is this a common nexus thing?

same here, really starting to piss me off when i see people talking about 70% battery at the end of the day while my phone dies in 6 hours
Cyan?
Woah, I think this might actually be cyan's Rom.
I flash enomther's rom and i got display percentage at around 15-16% ...
I think cyan will look into this soon enough...
But for now... I guess I'm gonna wipe... :/ and stick to enom's or some other ROM...

I think the problem is only with a few people, but I know others are experiencing this. This might be something with the "latest" nexi. But idk, it's a mutual issue, a fix should be coming
Probably you are right...
But, I would like to know, what settings peolple use: like updating wheater every hour, emails, widgets,..ham many apps are running and so on, ... perhaps connected to...sometimes people dont even know that
Edit: I got my Nex in january.
The change in the display usage percentage is just due to the way the powermanager works. Its not using more battery, its just displaying how much power it is using more accurately.
have the same problem.
100% airplane mode ON no WIFI, in 5 hours 72% battery remains . (PHONE IDLE took most of this - my G1 could go 1 month with this settings)
IN 12 hours in was 6% and with LOW use of my N1.
Yesterday I removed numbers in my battery and it was a litle better, not much but a little. (about 8% better)
I had 5.0.5.1, 2 and 3 and everyone had the same problem!
CM please take a look at this. What do you need any LOG info or something!
Have you tried wiping battery stats, then charging to 100% with it off, then booting into recovery and wiping battery stats again, then charging to 100%? The few times I've had battery issues that's taken care of it for me.
I flashed cyan again with a wipe (again), but got the same thing.
On enom's rom, I get beastly battery. I think we just have to wait for a fix for the people who are affected.

Do you need root to wipe battery stats? how do you do it?
Well I did the wipe battery about 3 times and in OS it was already green light 93% full.
I WIPED and put the power in on NON POWERED PHONE. It took 1 hour more to come to the green light . than I wiped again and went to boot up.
at 11PM i had 100% battery went into airplane mode wifi OFF.
And i did one other thing. Some of you had the battery drain issue with trackball wake. So I disable it.
7 hours of this and I got 97% - beautiful
before that I had 72% so there is a difference.
Now I have to see if the wakeup trackball is the cause of this or the wiping the battery stats.
Will eliminate one and other and keep you posted
I took my phone off the charger at 4:30am and the next day at 5:30 am i had 12% battery left. i used my phone a total of 3 times. most of the time it was on standby. i have setcpu with my phone UV and UC to try to save battery with profiles set up. in battery information 85% of the phones battery went to cell standby. Any suggestions on how to improve this?
Try wakeup trackball OFF in spare parts and battery % OFF in upper taskbar.
I have now from 100% to 59% in 7 hours. wifi ON all the time.
I have tried to wipe battery settings and charge fully with the phone off, but after the full procedure, I still get the same end result. I attached a picture of my battery usage.
Im pretty sure i saw a post online about the newer nexus's that were released having a better display. If this is true then wouldn't the phone's hardware alone be using more battery?
I can confirm I am having the same problem. I wasn't sure until I checked battery usage overnight. It used to be that with my phone on airplane mode I would use about 2% while I slept. Now, it's 9 or 10% with "Phone Idle" taking the lion's share of it.
I have tried deleting batterystats.bin after a full charge; powering off (while on charger); charging up to full again, but this has not solved the problem.
A few notes:
When the phone is idle (but not in airplane mode) it uses about 1.5% per hour (compared to about 1.1% in airplane mode)
I am using setcpu profiles to keep cpu usage right down when idle
Around the same time I upgraded to 5.0.5.3 I also started using the himem version of fastboot. And yes, if you suspect I don't know what I'm talking about here, you are quite right
For my next trick, I will try resetting battery statistics via recovery. What fun!
I've kept the cyan rom, and changed some settings to increase battery life. I turned off the battery percentage icon, and turned off the trackball to wake. I still got that the display was using a lot, but the battery still lasted pretty good. I guess there isn't too big of a problem on my side. It probably is the "newer displays" on the "newer" nexi. Maybe there really isnt a big problem
I changed now from CM to Enomther's TheOfficial Nexus1 1.8.1 and battery now works great.
I unplugged the charger at 12.00 am at midnight and with quite good use, not extremely havey but a good use I had 30% battery left at 20:00 (08:00PM) that day.
I lost only 2% from midnight to 7:00AM in my airplane mode and with Gmail check 10 min of phone calls wifi ON all the time checking web pages and showing off my live wallpapper at my work I had at noon (12.00PM) 70% battery left!
I LIKE IT!
now I'm thinking to push Kernel - .32 & .33 to see if there is any change with my battery
http://forum.xda-developers.com/showthread.php?t=653598
After resetting battery stats in recovery, I still lost about 10% overnight while on airplane mode.
For my next trick, I'll use a task killer like "Process Manager"* to keep everything unnecessary switched off overnight. Maybe I'll be able to narrow it down to an application if it's not something integral to the actual ROM.
*Yes, I know it will use up the battery too

Phone shutdowns itself when battery hits the 7% mark

I'm trying to nail down if this is normal behavior or not my phone always shutdowns itself when the battery level goes below 7%, no matter what.
then I turn it on it boots and shows 0% of battery left then it shutdown again, next time I try it's totally dead.
Tried with a battery calibration improved the overall battery life but that mark is still there.
Is that normal? I mean when I used to have a G1 it lasted until 1% or so.. 7% can be very well an extra hour of usage that I'm loosing.

I've noticed the same thing. It'll be interesting to see if anyone has a solution.
7% of battery life is just a number. It could very well be inaccurate, and simply reporting 7% when you actually have 0%. When you reboot and it shows 0% just backs this idea up. You are not "losing" an hour of battery life, you simply never had it.
To check this, use spare parts to look at the voltage of your battery when it approaches 7%.
Also, this belongs in the QA section.
I'll give it a try, interesting is the fact that both Cyanogen RC3 and Battery Monitor are reporting the same thing.
Will keep an eye on the voltage, what should it say ? something near 0?
seriously?
AFAIK li-on battery never be below 5% or 7% why?
because if you get below of this the battery will be dead and will not work anymore. so thats normal.

I've also read its normal but if its normal why isn't it calibrated to show 0% when its actually at 7%? My phone goes off at ~10%
btw there are so many battery threads lately.. http://forum.xda-developers.com/showthread.php?t=702167
Yeh, mine also goes off at around 10%.
it seems normal then , time to get myself a spare battery ... travel can be painful if no power outlet / usb port is near me
Yes its kinda normal. My phone has always shut down at 8% from day 1. I think its because of what we're talking about in the battery cal thread personally.

Xperia SP battery issue?

Hi
I think I might have an issue with the battery on an xperia sp which I got a few days ago. When idle with stamina on it's loosing between 1-2% per hour. I've used Gsam and recorded some stats to show what's using up the battery when the phone is not in use. Hope it makes some sense
loosing ~2% per hour phone in idle screen off
Stamina on, GSM only
Tried airplane, not much difference
Tried Stamina off, no difference
Charged to 95%
61% @ 10:16PM
34% battery use - of that
screen 56.3% (1hr 47min)
phone radio 6.5%
wifi 3.7%
apps 33.3%
TOTAL DRAIN ON BATTERY
-------------------
19% screen (avg 0.18% per minute)
2% phone radio
1.2% wifi
11% apps
____________________________________________
13 HOURS IDLE LATER - 17-20% BATTERY GONE
____________________________________________
44% @ 11.04AM(QUICKLY DROPPED TO 41% in around 2
minutes)
51% battery use - of that
screen 49.8% (1hr 48min)
radio 13.1%
wifi 7.4%
apps 29.6%
TOTAL DRAIN ON BATTERY
-------------------
screen 25.4% (WHY THE INCREASE of 6.4% when OFF all the time?)
radio 6.6% (+4.6%)
wifi 3.78% (+2.58%)
apps 14.8% (+3.4%, not sure why, stamina turns off all apps?)
6.4 + 4.6 + 2.6 + 3.4 = 17%
Why are these using up so much power in idle with stamina mode on?
Hello,
remove your simcard, reboot, got in to flightmode and let Wifi enabled.
now let phone unused for 8hours. its all Ok then accu should drain only 0,05%/h.
This is my XSP which i use only as alarmclock an every day 1 hour as Musicplayer.
I have tried without the sim card but it didn't do anything.
I notice in your screenshot though that there is no connection to 'mobilfunknetzsignal' ... mine is there even when the sim card is out, how did you get rid of it?

You must enable the flightmode under "settings->network->more" .
and then please install BetterBatteryStats to see if you have wakelocks and your device go in to deepsleep after turn of the screen.

Ah yes.. I tried flight mode one night and it still lost 15%
I have also used wakelock detector and it says phone is in deep sleep 99 percent of the time but still the battery is draining 1-2% per hour
Right now the battery is 27% down from 44% 2 hours ago... and I have hardly used it. I'll recharge and try again without turning screen on at all and see whats using it up.
Is there any explanation why the screen used 6.4% of the battery overnight when it was off all the time?
I'm too having about same problem..and am really interested in answer/solution,,,
Please, anyone?
I think I have fixed it but not sure. Phone was charged 24 hours ago to 99%, now its 94%. Definitely not using alot of power with stamina mode now but the screen was only used for 5-10 minutes, I've yet to test if it acts the same after screen has been used for a long time before going idle.
What I did was run phone setup again and update all apps
Now 88% after 40 hours, screen on for 25 minutes. Xperias battery monitor and gsam show completely different usage, android system takes up the majority in the xperia one but only 10% in gsam (under apps)
I checked wakelock detector and something called 'syncloopwakelock' was on for 4 and half hours. Is there any way to disable this? I already have auto sync in settings turned off.
A phone is meant to be used. Using it only from time to time to have as much standby time as possible is just a waste of a good phone.
I can get two days with heavy use. A lot of music, whatsapp, facebook and XDA Premium app..

I know, but there was a clear issue before as the battery was draining 20 percent overnight reducing the time I can actually use it. I was getting 5 hours screen on time one day, and only 2 hours the next. Just trying to make sure it has stopped, seems like it has
Would like to solve this syncloop thing though. I have no interest in syncing any accounts as I don't use them.
Simple fix
Change your rom, stock rom eats so much battery and has so many bloats, apps keep running in the background all sony apps.
MIUI is on jellybean and it gives me average of 1 day 20hours on normal use with wifi always on and sim card inserted..texting call and stuff
Problem has returned, woke up today to find battery under 50% and it was at least 75% when I went to sleep. Wakelock detector doesn't show anything and says phone was asleep all the time. Sony's battery graph though shows the phone was awake most of the time, but I can't find the cause in GSam or wakelock detector.
i think i have a idea. it can come from WiFi. there is a bug in all android 4.1. Set Wifi to allways on and deactivate/delete LocationBasedWiFi app from sony.
you can found it with BetterBatteryStats under Process.
Some screenshots
in this screenshoots the problem is not shown. When it comes from WiFi driver it is not a app that drain the accu, but a process.
The Line with awake in history details you can ignore, its buggy in 4.1.
I have searched through everything in Wakelock Detector and only process I found with alot of time is syncloopwakelock which is 4.5 hours. But this was already about 4 hours when battery was 85%
If I buy BetterBatteryStats will this show the problem? As you an see it drained at slow rate for 2 days then suddenly started dropping faster yesterday. I made no changes to Wifi settings, it is always on ... and I use Stamina mode.
Yes BBS will show the problem as "wifistatemachine", if the error should really be come from. you must not buy it, search on XDA for apk.
but if it come from your syncloopwakelock then i can not help.
Holy crap
I charged the phone to 96%, used it for 30 min (down to 92 percent) then went to sleep. Woke up and it was 28% and kept dropping !!! I've checked BBS, Gsam and I can't find the cause... again. After uploading these SS its at 12 percent.

Inaccurate battery %??

After charging my battery fully to 100%, I unplug it from the charger and without even turning the screen on, the battery drains to 92% within one hour. I check the battery stats and there are maybe only a couple wakes during this time.
Sometimes, the battery shows a certain percentage longer than others. Example, my phone will be on 65% longer than it would be on 60%.
Battery still gives me a solid 2 days usage with about 3+ hours screen on time. The service menu also says that the battery is good.
Is there a way to get the battery reading to show more accurately?
Thanks,
Hope I could Help You
For your battery problem, I guess you could try calibrating it. And also try to install "Greenify" along with "Clean Master or 360 Security" and try to close all running apps before turning off the screen. I also turn on Stamina Mode when the battery is at 100%, in an attempt to further save battery life. And the result has been kinda meh, but well, battery drains about 1% per hour. It lasts about a day and half with light usage. In my case, light usage being, browsing, youtube videos for about 2 hours, listening to music, social networking and taking some pictures

Hey,
im using greenify (my phone is rooted). Battery is quite good for me though. I get about 3 days with light usage. I start charging my phone again when the battery gets to anywhere between 10-20%.
I read that maybe its better not to let it get so low?
I have no wake locks either.
Umm.. IMO, 10-20% is okay. I usually charge the phone when the battery gets around 5%. I read somewhere that charging battery too early can affect the battery's overall standby time (reducing it). It's better not to let the battery reach 0% though.
I had that happen with my Samsung Galaxy Note 2 earlier. I once let the battery dip all the way to 0% many times. After a few charge cycles, I found out that the battery was dead and wouldn't charge at all so I ended up buying a new battery :-/
Umm.. Coming back to our Z1's, could you try putting the phone in stamina mode everytime the phone is kept on standby mode? This boosted my battery life a lot I even put my phone on stamina mode throughout the whole night yesterday to test the battery life again, and when I switched on in the morning, I saw that the battery had dipped by just 2% (standby time of 7 hours). I'm really confused how your battery drops so fast, 100% to 92%.
Could you try calibrating the battery and then putting it in Stamina Mode while on Stanby and tell me the results? I hope I could help :fingers-crossed:

Standby drain

When you sleep, does your phone sleep, or does it stay up all night and crunch 1s and 0s? Rate this thread to express how you deem the speed at which the BLU R1 HD's battery drains under standby conditions. A higher rating indicates that when the phone is not in use, the battery drains minimally.
Then, drop a comment if you have anything to add!
Good very small drop while not being used, even when loaded up with apps.
I experience pretty bad battery drain on idle. Basically, if I leave my phone alone without turning on the screen, it would be fully drained in about 30 hours.
I've reset the phone many times but phone idle always remain as the top battery draining app. averaging about 100 mah per hour constantly.

Exactly this! My phone uses more battery while on standby than with the screen on watching things! I don't understand this behavior. Powernap + Greenify + Amplify doesn't solve it either, even the things that keep it "awake" are hibernated and also delayed by Amplify. Wakelock detector doesn't even detect any apps that are running during standby either. Also, I have no bad signal because it is always on full bars or 1 less than full.
If anyone figures it out I would love to know how to solve it.
I get this too. Im trying to debloat the rom of some apps that seem a little suspicious. Will do this tonight. Already backed up my current system partition in case I break something. Wish me luck! :good:

Tell us how it goes. I have actually converted the Amazon ROM to the OEM version, however, that doesn't fix the problem.

Me too. And I have debloted OEM rom to what I consider closest to slim or stock. We'll see later how it goes.
i've pretty much ran the Prime version debloated or the OEM debloated, same thing. I think it has to do with the phone radio and Android 6?
When I put it on airplane mode with only WIFI turned on, phone idle isn't as bad.
Maybe its kernel controlled? Have u tried flashing the 6.6 updates radio.img? Does it contain one? I only used prime to power on the phone from then on only OEM version debloated. And as you say its always consuming batt on idle. I'll give airplane mode a try today.
Alright, I have just installed the xposed module "MobileRadioActiveFix" so this will confirm if it is in fact the data that's impacting standby battery. However, not too sure because "Intelligent Battery Saving" does disable data over time and the draining is still happening in that mode.
Anyways, I'm going to be testing this and report back. @l33chpda @Alex_XV6700

I figured it out, I was monitoring the CPU states and the CPU is not using a hot plug. It nevers makes a core go offline even when the screen is off and it will ramp up while the screen is off because there doesn't seem to be a cap when the screen is off.
I think the only way that we are fixing this is if someone makes a kernel with a hot plug in it.
With Prime 6.4 mine lasts a month on Wi-Fi.
Have you guys tried turning on the "Standby intelligent battery saver" that's built into the OS?

Yes, it doesn't make a difference. I do consistently get 4-6 hours for every two days, however, I can get more if the idle battery life is not there. For example, with your chart, my idle time would be about 45%-55% above the screen.
It's just the way it's reported in this ROM. Instead of looking at the battery stats, just look at the actual battery life of the phone, which is fine.
I have stock V12 vanilla ROM, and I find the standby drain can at times be worse than when I'm using the phone, and I'm not sure why. I'll put the phone in airplane mode and put it to sleep right after unplugging it from charging overnight and when I check on it in an hour or so it'll be down from 100% battery to 90%. When I turn off airplane mode and use the phone normally from that point on, battery drain is normal.

Yes, I experience the same thing! However, overnight, it drains about 10%-20% even though looking at the stats it is not even awake! It should only be draining about 1%-3% because it is not really doing anything at night.
Even the screen uses less power than the standby. @waingro808 could be possibly right that it is just reporting the battery stats different, however, on other phones with the phone idle, that percentage is very low and not as high as ours.

The battery stats dont add up either...
As you can see in my screenshots Im still 14% on battery
And it states that between SOT and Idle I have consumed more than the 2500mAh that this phone has on the battery.

Exactly. Ignore the stats and move on people
I got to 48% battery after 11 days, with "Standby intelligent power saving" enabled.
