Battery issues

Hi guys. Need some help. Very happy with my nexus 4 but, and its a big but, i am having some serious issues with the battery. I am struggling to even get 2 hrs of screen time on my nexus 4. The battery cant be this bad. Is there any way i can see what is exactly causing my battery drain? Sync, nfc is turned off. No widgets r running. Cant understand it. May have to rma this thing.
Help please.

This is probably the cause of your problem.

Stock. Not done anything to it

What kind of apps do you have?? Like apps that you think might drain some battery. Also use betterbatterystat app to monitor what's waking your device.

With stock, around 2 hours of screen on time is typical. You can prolong the battery life by disable Google Now, location service, email sync, Playstore auto update, etc. Check your battery stats (try better battery stats from the store) to see if any third-party apps drain your battery.
The better way to do it is to unlock bootloader, root your phone then flash a custom kernel. I recommend franco.Kernel. 3-4 hours of screen on time is typical with franco.

Might as well flash a custom ROM with it if you're going to use a custom kernel IMO. When a new OTA, OP will have problems updating to it because he is using stock + custom kernel + custom recovery.

Here is how to fix your battery problem.
1. Turn off location access in Google Maps settings.
2. Wait about a week for the battery to go through its charge cycle 6-10 times. Let it get as low as possible without the battery dying (this is really bad) and be sure to let the battery sit at 100% for atleast a half hour or so when fully charged.
Each day you will see your battery life increase and when done, you should be getting around 5 hours screen on time.

Well dramatic change in battery life as displayed below. Now after having a read in several topics it seems like a fix is to have the wifi on. How strange as this goes against the ethos of all previous smartphones i have owned i.e. wifi on drains battery. I have uninstalled a few apps and also switched of location access, so to be sure that the fix is wifi related i will switch wifi off the next time i do a full charge and see how that behaves. By the way android os is way down in battery consumption now.

Weird Battery?

I just installed apex launcher yesterday and thought id change the power toggles icon to battery to keep an eye on how the launcher would affect my battery life. A few hours ago i charged my phone fully. I noticed the battery went to 98 percent fairly quickly but then it went back up to 100. I checked my battery stats to make sure it wasnt just the power toggles playing up. But the graph actually showed the battery percentage going up.
Any ideas?

Is your device new?

The battery meter and graph are more of a rough approximation of your battery. It reads off of the current the battery receives. If it spikes you could see the battery graph drop a little and then go back up.

AW: Weird Battery?
I had this 100-98-100 bug, too. Happened to me 2 times. It seems to be just a small bug, doesn't bother me too much.

Odd, mine seems to be a lot better battery wise since 4.3... You might want to use BetterBatteryStats to pinpoint the cause (maybe some wakelocks etc.)

Flash a custom kernel.

Yes, me too, battery seems worse than in 4.2.2. Or is it just because that I use it more now i.e. to restore apps etc?

Really? Oh no!!
I'm still waiting on my ota update

Im gonna go back to 4.1.2 because it has the best battery life which 4.2.2 and 4.3 doesnt have

me too. Really hoped android 4.3 fixed this problem ;(

been having this battery drain problem ever since 4.2.2
Do you guys have this drain problem in IDLE mode? because I do..
rough estimate, it drains like 7 to 8% in one hour when my device is in SLEEP mode..

But to all this, what apps or services seems to be draining the battery?
Sent from my Nexus 7 using Tapatalk 2

I don't know what your talk in about, I'm getting better battery life than I ever did before. I'm UV by 25 running faux kernel (u21), and clean ROM. I just removed all the gapps I don't use, and don't run anything that needs background syncing. Did you guys do clean installs(full flash via fastboot)?
I also turned off daydream which I am suspicious of, yet I have no proof that it does anything

Thats the problem, I hard factory resetted several times and leave it alone with no new apps
installed before.. disabled NFC, my mobile connection.. and still it drains like a leaky hose in idle mode..
some friendly ppl here suggested installing greenify and betterbatterystats and stuff..
but it doesnt really help me pinpoint whats doing the draining.. maybe because I am not sure what I am looking at..
end result, i even flashed (nearly bricked my nexus on several occasions too) and still the drain is there..
I thought my battery is dying or something.. but my nexus is barely 6 months old.. and battery status shows it as GOOD..
so yea, I am stumped..

Yeap.
I am having the same problem with the battery, the battery is spent very quickly, I have less applications installed and lately I have not used the phone to see if it was me and nothing. It may be because manually install the OTA?

Does the rule of waiting a few days/recharge cycles to get a true sense of the battery not apply to Nexus devices like it does to Samsung devices?

The initial battery drain after flashing can be attributed to apps conducting their first sync and the kernel "settling." This only takes a matter of hours at best. After that, one can get a fairly accurate idea of how their battery is being tasked.

i used to get horrible battery drain until I disabled google now.

I'm also experiencing severe battery drain after taking the 4.3 update on my stock, unrooted Nexus 7. It's been 3 days and no improvement.

I too face same problem, and the App sucking most of the battery is "Kernel (Android OS)", second one is "Launcher", "Phone" and "Android System".
Any suggestions solutions found for this battery issue?

Phone Idle Battery Drain (Deep sleeping & no wakelocks)

Does anyone know why this is happening? My phone deep sleeps but loses ~10% per hour. I tried replacing the battery and restoring to stock but nada

uuuhmmmmmm quite weird... I think that must be a hw issue.. did u contact google? does this happen with every kernel?

I got my phone from a carrier in Canada and they will not honour the warranty because I bought it outright. I have tested stock and franco

Install BetterBatteryStats and see what the other wakelocks are.
Sometimes WakelockDetector does not show every wakelock that is happening.

And look what i said, WKD does not seem to be able to see all the wakelocks, install BBS and see if you get any extra wakelocks.
If that doesn't help, i would suggest you to do a complete reflash to stock and see if it still happens on stock.

turn off your wifi when you are not using it. there is a constant drain with a wifi connection.

Drain is STILL there with wifi and everything off (airplane mode)
I installed BetterBatteryStats and everything seems normal. In a 1 hour period the largest offender was msm_hsic_host and sns_async_evwakelock and suspend_backoff with a total of 4 min.
It seems to drain the same whether I use the phone or not.

I have tried restoring to stock. Drain still remains

Anyone have any ideas? Here is more info

I was after a red light I bought a new battery because I wanted everything back. but after replacing. the phone loses all the time very fast.i think is battery fault. I tried all the ROM and the kernel and does not help

Seems like the exact same issue. Have you tried using another battery? I am being sent another battery to replace the one I bought so I will try that when it arrives.

I not tried yet. I wait for the 4.4 ROM and if not help i buy new battery but from someone else

I have a question. as you put the batteries you put blue tape too? It's a bit strange but maybe this is the reason because I threw my to the trash.it is called blue anti-electrostatic discharge tape

What blue tape? Do you are exepriencing usb connection problems too? I have all those symptoms after I've replaced my battery, and also the usb stopped working

Well, I didn't replace mine.. Could it be the culprit? Where can we buy that tape?

I doubt the tape is the issue.
Have any of you tried using another new battery?

Did you mean when the screen is off? Because obviously it status awake while the screen is on. But there may be an app keeping it awake. Make sure all your apps are trusted

when the screen is on. ive never experienced this when its on Jellybean 4.3
and all the apps ive downloaded are from Google Play Store of course.

I'd go for a wakelock detecting app like "better battery stats" or "wakelock detector" to see which app could be the culprit. "Greenify" could then be used to block that app from keeping your tablet awake.
I personally do have no issues with standby whatsoever. I'd say I lose about 3-4% of battery during the day on 4.4. (WLAN and sync on all day, but I'm taking it to work where I have no WLAN I could use). I guess I had the same mimimum drain on 4.3. So standby couldn't be better on N10 in my opinion.
I only had one issue so far, where at about 25% of battery left it suddenly began to drain like 10-15% an hour, thus leading to my N10 shutting off after about 2 hours. No idea what caused that drain in standby.

I second that, get better battery stats or something similar to see what's keeping it awake.

AFAIK, BBS needs root in order to use em. And i cant root the N10 as it belongs to my mother

You don't need root for bbs

mhm ... will not install 4.4 if the battery life is that terrible. Did you guys control the typical Google apps, which usually like to eat a lot of battery?

I have this since 4.4.2 on my Nexus 10 and 7v2. Not on the 5. My N10 uses almost every juice for Android OS. Before it used 5% for 1-2 days for standby. Now 3 hours. See screenshot. Is this normal?
And it wasn't awake. See other screenshot.
