[Q] Charger got wet - Nexus 4 Q&A, Help & Troubleshooting

Hello, My original LG wall adapter got wet, i wiped away all the water i could, and let it dry out for day.
After that I plugged my N4 into it, and my battery just jumped from 70% to 100% in a blink. I unplugged it imminently, and phone thought it was still charging for like 10 seconds, and then my battery percentage went back to 70%.
It's been a few days since this event. I'm worrying about whatever damage it might have caused.
Battery life isn't great. i get about 1.5 SOT when I hit 40%. standby time are as the used to be, but when using the phone the battery seems to drain more. (WIFI OFF WHEN NOT AT HOME ,ALL GOOGLE LOCATION SERVICES DISABLED, ON 3G 24/7)
Is there any real test to see if there is really any damage ?
I hope I'm just imagining. Maybe the charger didn't went bad at all? after all is it a known bug when nexus jumps to 100%.
The wet adapter charged my Other galaxy S2 just fine..

Here is some ridiculous screen.barely 10 minutes screen on an a short phone call and its already down 5%

5% down, in 1 hr and 15 minutes, with 10~ minutes of screen on time, and some phone calls is not really that bad imho.
You should probably get a new charger, seems like something is messed up within the charger, due to being exposed to water.

Is there any way to determine if the phone itself received damage ? I's there any chance at all ?
Only the plastic of the charger was exposed to water ..
anyway I'm using apple Iphone adapter since then.

I think the best way to tell if it received any damage is to just use it normally.
Charge it normally, through the iphone adapter for now, and see if the problem re-occurs.

I do notice battery drains quicker , My friend's nexus, which was from an older batch, drained 2% after 10 mins in google chrome, auto brightness.
mine drains 8% , same brightness, no application running in background. betterbatterystats shows nothing unusual.

Is this normal? Totally Moderate use.

That looks pretty on par with what I would have expected for me...

I think you're overreacting. Get a new charger, and charge through USB or whatever for now. If you're super paranoid, then flash a fresh ROM with data wiped and your battery should be pretty good..

Your battery is fine.

Yes it's normal and depends on screen brightness.
and by the way the voice calls that you have made seem to take a large percentage
:cyclops:

If you're not happy with your battery life give Franco's kernel a try.

Nexus 7 Battery Life

Hi! I recently got a Nexus 7 and I am somewhat disappointed in the battery life. I am only getting around 3 hrs of battery life and is draining quickly while idle. The battery is also draining while being used while connected to my pc. I am using Jellybro rom along with Trinity Alpha 64. Can anyone recommend the best Rom/Kernel combination for battery life ? I read that Trinity is great for battery life so I'm doubting the Rom (however it works great on my Galaxy Nexus). As I dont always use the same things on my tablet I cant really test the different roms myself.
Thanks

I'm getting great battery life on my stock N7 :|
I tried it the other day, used it all day and it died after around 8-9hrs. Was tethering via bluetooth, brightness set to auto, and either played games, used FB messenger, or read Wall St Journal frequently throughout the day.
Sync and location enabled.
Oh and the N7 will probably discharge faster than your PC can charge it. Typical USB ports on a PC only output .5A of power. Chargers meant for tablets usually provide about 2A of power. So thats another issue.
Might I suggest running the N7 till it shuts itself off due to no battery, then letting it sit and charge overnight till its 100%?

If its enough to make you mad then its prolly not right.
To say your doing in wrong would be a far shot but your tablet is definitely doing it wrong..lol. I was just saying the other night to my girl that I was super happy with the battery because it lasts all day for me. From 7am in the morning till 12 at night. Of course im not using it every waking moment but I do check it/use it as much as I would have normally used my phone. During work I am on wifi till about 430 and then from 430-8/9 while im in class im tethering using it almost the whole time, then when im home for the rest of the night I will be on wifi. The things I do vary from webbrowsing (reddit, xda, etc) emailing attachments, listening to google music and GPS/texting. (yes I use tablet talk which is why I rarely use my phone anymore except to setup tethering)
If you are having any issues with your battery I recommend to get a battery app to reset the stats and try again. If not return to stock then try that method again.. then if NOT return.

Just turn off your google account auto-sync and your battery life should increase dramatically. I use the power widget to toggle sync.
Okay here are some screenshots of my battery life... Not sure if its uploading properly though since im doing this through the app.....
EDIT: Looks like it didnt work... But basically I had about 20.5hrs of total battery time. Screen on for a total of 5.5hrs. Bluetooth on the entire time, WiFi on for about 6 hours.

My N7 discharges faster than the google provided AC mains charger can recharge it. That seems pretty pathetic to me. How is it for others?

Nexus 4 battery destroyed itself!

My wife has a n4 and the battery doubled/ballooned to over 50% of its original size breaking the back glass amd causing what seemed like all kind of software issues. It was hard to tell at first bc it was under a case but when removed the bak was all cracked. The camera when used would crash the phone and show it battery stats a wierd cliff event. Replaced the battery and all is well

That's what I call a really defective battery...
Cann you post the first 5 or 8 characters of the serial number from the box? This might be an isolated issue for a single battery or a line of devices with the same supplier for the battery.
Haha this reminds me of my old HTC hero.
As that was a removable battery it was encased in a plastic housing.
I just remember coming to it one day and finding the back cover half off.
When I removed it the battery looked like an egg!
Funny enough I just squeezed it back to it's sort of original shape and it still works fine to this day (backup phone)

It happened to me also.
My N4 was turning off randomly and draining battery suddenly from 90% to 50% on so on. I sent my phone to LG service center and they said they have no solution for this problem. The second day my battery doubled size and the back of the phone was no more flat (luckily it didnt break). So i went and changed the battery now my N4 is working fine again with no problem, but sometimes it get overheated with no reason
My battery isn't bloated, but after a red light of death, I'm getting about 1hr 30 mins on 3g (used to reach minimum of 3hrs) and 2hrs or less in wifi (used to get 5hrs+) which sucks :/, gonna get a replacement tomorrow.

Same thing here, my battery life is horrible and it shuts down at 2 hrs sot no matter what, I also noticed that the back isn't flat anymore. Probably gonna have to get it replaced. By the way how much did you pay for the battery? And would it be covered with the warranty?

you should RMA as its abnormal and unacceptable to occur, if you have your battery connected while the phone isnt in use for a long time it can expand, ive seen it in my old phones left in the drawer.

I mailed them about my problem and they said they would RMA my device if i was in the US now.
So i want to an LG service center it costed me 33$
I am thinking about RMA but I will be leaving the country for business this Saturday for three weeks. So I guess I will wait a while, hopefully its not dangerous and the back doesn't crack

Whoa, sometimes by phone stats go crazy, but that one on the right is strange. Probably need to hit a few cycles to get the stats accurate.
Is it normal to see an uptick in battery even if the device is not plugged in to recharge? I'm guessing this might iron out after the battery stabilizes a bit, but I am definitely noticing that after use, if I leave the tablet on the table unplugged and return to it a while later, the battery reads (sometimes significantly) higher than when I left it. Battery history also shows a rise as well. I just think it's strange, as the unit was not actually plugged in or charging during that period.

My old phone used to mess with the stats. Let it run out of juice, charge full up with the device off, unplug, turn on and you'll have fresh battery stats.
From SlashGear Review
http://www.slashgear.com/nexus-7-2013-review-29292015/
Google quotes up to nine hours of HD video playback or up to ten hours of web-browsing from a full charge. Our own testing suggests these are pretty accurate estimates; with heavy use, including Netflix media streaming over WiFi, push email and social networking turned on, some photography, and browsing, we managed almost nine hours of use before the 2013 Nexus 7 ran out.

Thanks for the suggestions. I'll try it and see how it goes. I have gotten excellent battery life out of the original Nexus 7, so I'm hoping for similar performance on the new one.
have any of you guys run into the battery with exclamation mark @ 0%? I plugged it in and i'm getting nothing to indicate charge is going up. If i turn off the tablet, the charge indicator works and it's charging. after a few hours though, the charge progress is still the same (starting from zero). any ideas?
thanks!
Is anyone having Google services cause serious idle battery drain? It has to be caused by some Google app I have installed. I want to start fresh with an aosp ROM and install one app at a time. Anyone have any experience with Google services causing lots of battery drain?

WiFi eating battery on Note 3

Hey everyone,
My mom just got a new Note 3 (yay!), and I have been quite busy exploring all its features. One thing that is nagging me, however is that both the stock browser and chrome are using up a great deal of battery. Wifi is eating 1% Every 1-2 minutes and while using the browsers this is amplified to a percent every 30 secs!
Please help me.

Do you have brightness set to 100%?
How far are you from the router? A bad signal uses more power.
Is anything syncing in the background?

At stand by, the Note 3 hardly uses 1-2% battery every 8 hours or so, but when it comes to calling (core function of the phone!) and wifi+browsers the battery suffers greatly. I haven't tested cellular data yet because of weak signals near my house. Should I let it drop to 0% and charge to 100% or get a new battery? Really disappointed with the battery.
As a general rule you should avoid full discharge/recharge cycles (except for things such as recalibration) as this in the long run shortens the batt's lifetime even more. So it's best to recharge it more often and keep it somewhere between 10-90%.

UPDATE
New update guys:
I left my phone with WiFi on for half an hour and it ate 3% battery from 50% to 47% which includes a phone call. And this time the phone was a bit further away from the router. So, I guess it's not the WiFi that's sucking the juice but the browsers.
Any fix for this?

Hey,
Well the issue fixed itself. I now have WiFi running with Smart Screen, Air Gestures, Sync, Screen Rotating and using the web browser to do some surfing and battery hasn't dropped a percent since the last few minutes. It got fixed right after another (it's 3rd) charge and it's working now.
Guess I just needed to charge it a few times for it to work. If anyone else is having issues and have charged it only once or twice, try charging it again. Mine was at 47% when I charged.
Requesting a mod to lock this.

How long your battery stay at 100%

Hi all!
I just bought my g2 for a week, after flashed slimkat, I found that the battery stay at 100% for quite long time. In my case, at least 3.5h, include 12 minutes screen on, 3 minute phone call.

Yeah. Its been estimated that the 100% to 99% is actually about 5 percent. I think I had something like 30 minutes of screen time before I went to 99 percent. the standby time can be quite hilarious. I wish I still had screenshots, but I had one of my phone sitting for about 9 hours 100 percent the whole time . As soon as it drops to 99 percent my estimated time was like 980 hours lol

Yeah, this.. Staying at "100%" is completely artificial. As soon as you hit 99.4% it should show 99%, but I imagine that leads people to think the battery is depleting fast, so they've done something to make it show 100% longer.
What's interesting to me is that it's the same on custom ROMs as well, so it's not something the ROM itself is doing.

I think it's the battery technology that does that. Android seems to be written for different battery tech.
Also I don't like the flexible metering. Play for hours, set it aside a few minutes and battery percentage increases.
I hate it in cars also, I want a meter to show how much I got exactly lol.

On CM11 mine will usually adjust down to 99% fairly quickly. If I wake up and start browsing after taking it off the charger, the circle will get a notch out of it usually within about 5-10 minutes.

Basically leaving it charging despite having reached 100% so it trickle charges for an extra hour. It seems to have improved the battery life.
