Anker 10000 mah question. - Nexus 4 Q&A, Help & Troubleshooting

Had something weird happen to me at work today. My battery was at like 22%. Plugged in my nexus 4 and in a few seconds showed 100%. I said to myself huh?? That was quick of course I knew something was wrong. Unplugged my nexus 4 and went to 1%. Anyone know what causes this or had anything like this happen to them?

Happens to me when the battery calibration gets messed up. That means it usually happens after flashing ROMs or doing hard resets.
Nothing to worry about. Just continue with normal usage and the battery will calibrate itself after a couple charge cycles.

i wish it did.

I heard these Nexus 10s walk to a wall charger when you're not looking and then charge themselves up a bit.
Besides the bs, I think it has something to do with the battery just recalibrating. It happens a lot on my GNex and I usually notice the battery "increase" right after heavy usage. The heavy usage probably just made your Nexus 10 underestimate the battery amount.

Battery drain while phone is off

For the love of god i can't understand why my Nexus 4 battery is draining while it's off! Sometimes i use my iphone 5 , and always charge the Nexus 4 in case i wanna use it,i know it's already charge. 2 days ago i let the Nexus 4 completely charge, today i power up the phone and the battery was at 14%. It happened a couple times but was always thought ah maybe i left it on or something, this time i made sure the phone was off, but battery still drains... Im on stock rom never rooted, using Nexus 7 charger... Any idea on what could be the problem?? Thx in advance!

Maybe a bad battery?

I mean i don't have battery problem at all when i'm using it.... It's just when the phone is not in use and off it's still drains battery like it was on... I can understand something like that happening if the phone was off for a long period of time but 2 days 14% left while off seems ridiculous!

Try using the same cable and charger. Make sure Facebook isn't running or any apps that can drain your battery. Facebook killed my battery with no data connection

I just sent my first Nexus 4 in for RMA on this very issue, got the replacement on Friday, did a charge cycle, charged the phone fully up whilst off, took it off the charger (the official Nexus charger btw), and let it sit for the last day, just turned it on, and it's at 60%.... W T F !!!
This is sooo totally bizarre! I can only assume that this is common to most Nexus 4 (what are the odds of me getting two bad ones - direct from Google - with the exact the same issue?), and that people just aren't noticing, as most people don't leave their phones off after fully charging, and thus just never notice, as the battery behaves perfectly normally under usual use.
I would gratefully appreciate it if people could put this to the test, so I know whether or not to RMA the second device or not....
Was the phone powered down, or just sleeping? Any programs set to auto sync? Check for wakelocks?

Did you use the same charger with both phones?

I had similar issue on my old G2,it was because my battery was old and needed to be replaced.

Same thing happened to me. Only once though. Charging from 14% then jumped to 100% in seconds. Rebooted, and it's back.
Its normal, nothing to worry about. Something to do with battery reading and sudden change in voltages or something.
what rizy7 said above... Nexus 4 has a bit of wonkiness in reading battery level, sometimes. Not sure if it's purely hardware, probably a combination of hardware and software problem. Google, for a smart company, does some stupid things. Just look at how they have handled the marketing and sales of the nexus phones over the years. Pure disaster. LG made a brilliant phone in the Nexus 4, great industrial design and some great stuff innards too. Then Google punted on day one on play store. A total chaos ensued, buyers were getting their orders deleted after they were confirmed. Such inept online marketing. Also, where is the after-sales customer service? No wonder the Apple fanboi's are laughing at us.
Same thing happened to me while debugging an app with ADB. Rebooted and it shows the real battery level.
Use all ur battery until it is empty, charge until 100%. Reboot into recovery and press on wipe battery stats.

I use TWRP for costum recovery and there is no wipe battery stats.
Happened with me today. Twice. Why is the battery reading doing this? Pretty strange.

Weird Battery Behavior. Any solution? Or time for an RMA?

I have had this phone for about 2 months now and everything has been exceptional with the phone. Have seen people complain about the battery life, however it has been really good as far as my experience is concerned. However since a week I have seen the battery screwing up a lot... A LOT.
I always used to charge my phone daily in night. Plug it in..set an alarm of 3.5 hours (yes it takes 3.5 hours to fully charge from less than 10% stage) wake up..turn charging off..sleep back. Okay, some of u might think it is stupid but can’t risk of leaving it on charge the whole night and burn my phone. Anyhow, so, since a week what I do is I charge my phone whenever I want (read it on a few thread and articles)..be it 50%... 80% or even 92%. I just make sure its 100% whenever I leave home.
But something weird has started happening... The battery percentage keeps on changing.. For instance:
when I unplug it..its 100%.. within minutes of usage it drops to 99..then 98.. then 97 and suddenly it rises back to 100%. (Pics attached)
Sometimes when its on charge and I come to check SMSz and reply them.. battery % suddenly drops.. e.g: if its at 99%... it will suddenly change to 96% in a second and in a minute goes back to 99% .. so on and so forth. And sometimes even when its charging..if it is at 80%, it will suddenly shoot up to 100%. The percentage doesn’t change even after a reboot. Weird, isn’t it?
Now the most weird issue, since yesterday the battery life and dropped to 50% less. I used to get 4 hours OST and now I hardly get 2 hours. During night, the battery used to drop 2% in about 6 to 7 hours and yesterday it dropped 15%. There was this one time when it dropped 9% in 6.5 hours (pics attached). Tried seeing through Wale Lock Detector but there were no Awakes during deep sleep. Too weird :s
I don’t really know where did I phuck up as I haven’t installed any shaddy apps or something. Please advice.
My phone info:
All stock. No root (and not looking). No custom Roms whatsoever.
TL;DR... Battery acts weirdly. Shows inconsistent percentages. Suddenly shoots up. Suddenly Drops. And now the On Screen Time has reduced 50%.
It sounds like it's nothing more than a bug.

Thanks for ur reply. How to figure it out? And measures should be taken? Any suggestions?
this has really kept me worried since a few days.
This is "normal" for the N4, and the most/all of them do it. Unreliable drivers, or a hardware fault, not sure.
Here are other threads about the various battery bugs, but there are many more:

I know I searched many threads before posting and mostly had the Shooting up issue only, when charging.
Anyhow, this normal behavior has reduced my battery life a lot.. which I am not liking .. What to do?

Both my N4's (different H/W revisions) have been doing the 100 to 98 to 100 thing as well since new. Battery life is still excellent for me. An RMA would probably do the same.
Happens with my nexus 4 too. But this hasn't reduced my battery life at all...

You're pretty much stuck with that phone as you only have 15 days to RMA a device, your only option would be to send it into LG for a repair. My battery has acted up like this once so I stopped using the stock charger and it hasn't happened since.

Ok. Thanks for replies. Do u think Factory reset would do "anything"? better?

Rebooting might help. Could also be an app that updated that now doesn't play nice. You could try a factory reset just to clear out some crap but I'd back everything up just in case first. Not sure if a factory reset deletes all your user data in memory or not. I only did it once right after I got the phone so can't remember. Hate to lose all your pictures, files, etc. that aren't backed up.

According to that you should contact Google if you got it from the Play Store
Thank guys for your responses.
Kzoodroid, i regularly back up all my personal data.. Pictures.. Videos.. Music.. So thats not an issue. And all the games and apps r also backed up on my hard drive. So i guess factory reset wouldn't harm much in my case. Any idea how to factory reset N4?

Yeah, just go to settings, backup & reset and click factory reset.
By the way, I notice you use battery guru and I was wondering if that application really helps in saving/boosting battery life. Personally I like "Greenify". It's a great app.

It's normal. The N4 isn't great about showing the exact battery life. In fact, what you see isn't the true percentage, it's an estimation. Don't worry too much about it!

This is a question I can't answer along with any facts. I tried disabling it for 2 days and I noticed the OST reduced from 4 hours to 3.xx hours. May its placebo or something but then I enabled it...thinking if it's not doing any good then it's not doing any harm either.

Hmmm, I didn't know that. But why is that? Any apps or something to show the exact battery percentage left?
Happens to me once in awhile. Do a quick reboot, and if that fixes it, I would not worry too much.
Hmmm..
Yesterday when I woke up in morning.. the battery lost 2% only in 6 hours. I felt SOOOO relieved that my "good battery" is back. But who knew what was to come... today I woke up after 7 hours and the battery lost 15% .
My usage is always the same. I force close all the apps I use daily and turn wifi etc all off. So i doubt if its any app.

Nexus 4 dropped from 100% to 0%

Nexus 4 dropped from 100% to 0% while being in use. It was being used with usual apps like Maps, Twitter etc when all of sudden connections went AWOL.. managed to get it on only after connecting in charging for a while but it shown 0%-1% charge only.

Any suggestions welcome. I have placed the phone in charge via USB mode as of now
Stock 4.3 Android, not rooted
Sounds like a faulty battery. Why not RMA the thing for a replacement?
Can you put your phone on bootloader mode and leave it there to see how long does it take until it comes off?

Bought it this when it was launched in November. Working fine since then.. shouldn't be faulty all of sudden.
Seems SW flaw considering the fact that flat graph before sudden drop. No battery drain despite of usages? Shouldn't be

Already managed to recover it from the dead state and its on charging.. 9% by now
Really dont' think its a fault in the phone had faced similar issue but it was while charging, Plugged the phone at 5% battery and after 10mins it was 100%. Could be related to the OS also, Charger the phone till 100% and use it again should be fine now.
