Battery drain? - Nexus 4 Q&A, Help & Troubleshooting

Stock ROM, unlocked and rooted, flashed LTE enabler zip. Still on JWR66V.
Charged phone yesterday, went out, when I got home it was still around 70% battery so I did not put it in the charger. Woke up, tried to open Facebook messenger to read a message, app took a bit to load, so I just closed it and put the phone down. When I looked again, it was at 18% battery. Hardly used it.

Any ideas? Took it off the charger about an hour ago at 91% now at 79 with little use.

Turn off Facebook auto update and gps

Why would either of those things cause a battery drain like that?

Seems a little less since a shut down and restart. But still curious..?

You have Google Services battery drain. Check http://forum.xda-developers.com/showthread.php?t=2385843

Yeah, also make sure currents isn't auto updating..
Anything pulling data on a regular basis will use battery.. Notifications, etc because they cause the app to basically run all the time.

I get all that. I've never seen this much of a battery drop while the phone was idle.

Yeah, all my sync is on and i'm constantly connected to wifi. Never seen a idle drop that much.

Graph "gaps"/"skips" in Battery Usage

I noticed threads and questions about those gaps in the battery usage info graph, and had them too a couple of times. Every time my phone would crash and reboot, those gaps would appear !
Today i accidently stumbled on a possuble explanation of this:
I'll add some screenshots aswell; so in my current battery history, in the first screenshot i think (the stock statistics), i have two gaps, one big, and one smaller earlier. So, i turned off the phone and PULLED OUT THE BATTERY aswell cause i wanted to check my batteries mAh (its 1650 but thats offtopic). Thats how the small gap appeared, because i went and checked the graph immediatly. As for the big one, my phone seemed to crash and reboot while i didnt notice, because in an hour or so of no using i woke it up and it asked for the SIM PIN.
Also as a note, in the Battery Usage where is tells what apps ate how much battery, is written that the screen ate only ~30% instead of the usuall 60% ! Another sign of data loss.
So there, i think the phone crashes or something and doesnt manages to save the battery data, and those gaps ("falls") appear.

Terrible battery life

I have a huge problem with battery life on my G2. Everything started after playing with Kitkat custom roms and kernels.. With every single combinations (rom + kernel) I always have battery life problem. Yesterday I decided to go back to JB and see how it will works, but.. I have same issue on it.. I am using my phone for 19 hours and 2.19h on screen and 27% of battery left. What can I do to deal with this problem?
Also curious...

Here's an idea: Uninstall all that crap and test again.
Also, post English screenshot if you want help. This isn't a ->Insert your weird language here<- forum.
I'd clean reinstall a new ROM (I'm on cloudy G3 with native kernel) and just use Clean Master to help boost battery life. Mine is very good so far. Around 5 hrs of SOT and almost 3 days of standby.
To the OP,
Are you restarting your phone in either silent or vibrate? That's what caused my 1013 wakelock in the past. I always reboot without vibrate/silent on now, and have not seen this issue.
Secondly, game playing will use a lot more battery than normal. It heats up the phone and works the GPU/CPU. For example, my battery only lasts 3.5 hours with Ingress playing.
Third, looks like you have some Android OS wake locks. Do you have Google now/location settings on and reporting?

battery is draining twice faster

Hey everyone,
my Note 4's battery (SM-N910F) is draining really fast. I bought 3 new batteries (1 samsung from their site and 2 rav power) and my battery still only holds for like 3 to 4 hours (instead of the whole day as before).
Can you help me figure out a fix?
Thanks !
Android 6.0.1 is running.
Version number MMB29M.N010FFXXU1DQL2.
Baseband N910FXXS1DQA1
3 -4 hours when using it? That is great. However, if standby is affected then you need to see what is running in the background and affecting the battery. Use BetterBatteryStats and or Gsm Battery monitor

no, 3-4 hours when almost not using it ! Before, the battery was lasting all my work day. Now at lunch, it's done.
I installed Gsm battery monitor, here's what I get:

Do a search on android system battery drain and try some of the fixes. Something is running causing the drain. Google or other backup or something constantly syncing etc.
Finally, I did a full factory reset and now the battery is back to normal!

WhatsApp / Facebook on background alot of the time

Hey guys,
I bought OnePlus 6T last week, so far I'm really liking the phone but there is something strange with the battery stats:
I charged the phone yesterday to 100% before going to sleep, then left it out of the charger to see how much it would use, in 9 hours it used 5% (it's okay, but maybe it could be better?), the strange this is, from the dump file from BBS attached, you can see that WhatsApp and Google play services were using sensors all the time, what's is happening with them?
Also, on the process tab, it's showing Telegram on top, what does it mean?
Now, after 30% being used with 2.4 screen hours, I can see these stats on these stats on the battery menu:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",

"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
Facebook used 13% with 1:36 hours in use and 13:25 in background
Telegram used 7% with 0 in use and 0 background (I didn't even open it today)
WhatsApp used 2% with 19min active and 4 hours in background
Can anyone help with what might be happening here?
I attached a dump from BBS from the moment I wake up (idle) and from now.
Thanks.
Facebook app is just a rubbish. It's known for draining battery
Yes I know Facebook drains lots of battery, but that does not explain why it's running so much time in the background, I have checked other people phones and they do not experience such thing, this is probably something with my phone
get rid of the facebook app...problem solved, and you will have a happier life..

Baterry issues, randomly drops from 30% to 0% after plugging into charger

So ive had my s8 for almost a year now, and for the last month i started having some problems with the phone. Im not going to mention the display burn in and discoloration along the edges(I always have the brightness set to only about 50% and dark mode), the baterry has been acting up.
So one of the problems is that when the phone hits 15% and i plug it into a charger, the baterry percentage looks like a countdown, literally. I see the baterry drop from 15% to 3 in a 30 second span, in charger. But when i continue using it withou plugging it in it can last about 10 minutes with heavy use.
Also about 15 minutes ago my phone dropped to 0% after i turned the screen if on 20%, happened to me even with 45% before. I have screenshots of the battery drops.
Also i think i should mention that i have a custom rom, light rom. i had renovate ice before light rom for about 2 months, and now im using light rom for about 2 months aswell. The baterry problems started happening like 1 month ago.
And yes i have recalibrated the baterry(let it die and charge to 100% without turning it on, this is what i found. If you can give me a better tip to recalibrate it please go ahead.) Also the samsung codes on dialer dont work so i cant check my baterry info.
Thanks to anyone who can help.
