Hi. I'm a french user and I have a problem I can't understand. My firmware is XXDMB6. Yesterday at 22h I enabled airplane mode when I was going to bed and my battery was to 38%. This morning at 7am, the battery drains to 11%. I don't know what was able to consume all my battery. As I don't expecting it is this morning I did a screenshot consumption. What I can say is that the problem is located at" Android system" which is increased to 25% while yesterday it is "screen" which was first position. I also generated a logcat for those who know to read it. If someone could help me it would be nice. Thank you.
Attached screenshots: battery consumption and logcats
Try Juice Defender Ultimate app. it may help you to have greater battery backup.
Or-else if you don't have Perseus kernel, just flash the Perseus kernel. you will see the difference.

Hello There my phone is using quite a bit of battery at the moment, these two things are right at the top of whats using battery, cell standby 51% and phone idle 39%, surely this way too high?
my Baseband ends in 56 if this helps
im using doomkernal v10 and darkforest rc2 rom
and my build number ends in 42
is this all correct or do I need to flash something?
The % means nothing really, If you do nothing with your phone then they'll be at the top.
The more you do the less these % marks would be.
However if you have battery drain download something like better battery stats to see what is draining most of your battery.
That is far more accurate and their is a forum post about how to interpret the results etc somewhere on XDA
I have to agree with doncoop in terms of that you shouldn't really worry about those two stats.
All phones will enter the idle/standby phase in order to conserve on battery life. For example: After a full charge and reboot, my phone will last anywhere in the vicinity of two to two and a half days. When I check on the battery stats, standby and idle (typically equal to one another) will have the majority of battery % used (typically in the 65% to 80% range).
Can you improve on that further? I guess, if you decide to underclock your phone or use a LV kernal. But again, going back to what doncoop stated, using a program like Better Battery Stats can help locate background usage programs and how they effect your battery.
Hi!
I installed blackout ICS incredible in my DHD. Everything went well but I wanted to calibrate my battery.
So I downloaded Battery Calibration by NeMa from Google play. Before calibration my batterylife was about 12-24h depending on my use.
Now after the calibration my batterylife is about 5h!! And the same usage as I have always had, couple of calls, net surfing and maybe a little of Angry Birds and spotify.
Did I do something wrong or is my battery dead? My DHD is about 2 years old.
According to Google calibrating your battery (erasing your battery stats) doesn't actually do anything, so it shouldn't have made your battery life shorter. You could install BetterBatteryStats from a thread here on XDA to see if something else is eating your battery. Look at alarms and wakelocks.
Ok, thanks. I installed the BBS and I'll tell the alarms and wakelocks here if I don't find anything funny about them...
bananagranola is right.

calibrating your battery basically tells your OS how much batter it has or doesn't have. IF you flash a rom at less than 100% battery, then the max amount of battery your OS thinks it has might be different from how much your phone actually has. Sometimes this can affect battery life.
The other thing is, did you calibrate at 100%, then unplug immediately? If not, that might trick your OS into burning your battery so quickly.
Otherwise, 12hrs to 24 hours is super amazing, I'm a semi heavy user, and I'll only be able to get 12-14 hours of semi serious use (8 hours standby, 2 hours on off usage, some of that at 100% brightness when i'm outside, and lots of music), end of that I have only 32% left. 24 is pretty amazing, I wouldn't be complaining :laugh:
Well when you simply reboot new stats are generated.

Ok, so I have had today the BBS running on the background. I tried one thing in afternoon, I switched of Wifi. Wifi was off about 3h and when I came back to home I switched wifi back to on. I have still 70% battery!! and about 12h without charging.
BBS alarms:
android, wakeups:83 (Is this much?)
com.google.android.gsf, wakeups:56
com.android.settings, wakeups:13
and the rest of them is under 10
BBS Kernel Wakelock:
wlan_rx_wake: 14m18s
PowerManagerService: 10m57s
and rest is under 4mins
BBS Partial Wakelocks:
AudioOut_3: 3min16s
Twitter sync: 1m56s
BBS Other:
Deep Sleep is about 10.5h
Wifi On/running is about 6h
Is there something wrong or is there something that uses too much battery? Could the battery be "damaged" due it's about 2 years old now?
Sorry for stupid questions but I find it very annoying that sometimes battery life is 5h and sometimes it's way more than 12h with same usage.

What you've got looks fine (which makes sense, since you had good battery life this time). Keep BBS installed. If/when battery life starts tanking, take a look at BBS and see if anything else pops up. If you've got more questions then feel free to post again here.
Although you might miss the customizations of the roms, aospX has great and I mean great, battery life.

I was curious what kind of idle battery drain people are getting on their tablets/ROMs?
Measuring with Battery monitor Widget Pro, on my 8.4, running stock TW except for Towelroot, I am averaging -150ma.

Since I have an amper cable I can see the current the tablet draws when its plugged in with screen off / idle and fully charged. mine does this
0-0-0-0-0-0-0-0-0-20-0-0-0-0-0-20-0-0-0-0-0-20
so I would say its draws a quick 20 ma every 10 seconds - but since its plugged in it might not be in the deepest sleep setting that it would be when on battery.
anyways I have no problems with it staying at 100% or 99% leaving it off for the whole day unplugged so it has very good power management in my opinion. - just have to keep the wakelock apps in check
I updated from the ng1 build to the latest nk1 build and my idle battery drain is much improved with the exact same setup running. Now down to -40-50 mah.
I have terrible battery drain randomly for no reason and I don't no what is causing the battery to drain so much. I have attached an image is there anyway of seeing what causes this much battery to drain so quick?

You should install better battery stats, available here on XDA, to pinpoint your battery usage.
Looks like there was a really battery draining event that occurred quite suddenly?

I noticed in the screenshot you have might GPS on, there could be an app running in the background abusing GPS or polling it too quickly (look for a blinking / solid white pointer Icon in the top left of the statusbar, this will tell you if something is requesting location).
GPS will drain battery very quickly and should be disabled unless it's needed.
Experiencing strange problem with ultra power saving mode it is eating 5% battery overnight (frm 1am to 7am)in normal mode during day time battery is outstanding
What do the battery stats say about what app is causing the drain?
I read about a bug in Google music causing battery drain when using an Adblocker.
Perhaps battery saver mode triggers the same bug if it blocks internet access?
Look, i was just about to post a new topic about the same problem, heh
5am to 1pm, ultra saving mode activated by the switch on the left side panel.
51% down to 46% overnight. Dont u think it's insane considering it should go 0% ?
Im noot rooted yet or anything. It's my 4th day i use Lenovo P2
It was MM out of the box, right after i powered up my phone OTA asked me to isntal Nougat update, so i did.
Any ideas ? Im also not happy at all with overall baterry life. SOC is stucked at 1.67Ghz. like 85-95% of the time. It doesnt go into deep sleep which affects battery life 7-10h. I had more with Xiaomi phones and their 4100mAh batteries.
there is a drainfix.zip floating around. What does it do...exactly ?
Hi,
I've been having relatively high battery drain over the past 3-4 weeks and extreme drain today.
I went out the house 85% percent and was on 50% about an hour later with approximately 15min screen on time inbetween.
It didnt even make it through the work day with very light usage which it normally survives with 40%.
How can I find out what causes the problem? It is not rooted and GSAM therefore only shows very superficial information.
The wake phases have been about 3h between 1am and 7am... when I was asleep.
I am on 8.0.0 Exynos
Thanks
I hope it will be back to normal asap because I was pretty impressed with the battery beforehand.
I use BetterBatteryStats (Needs some ABD commands to give permissions but doesn't need root)
