Battery status not correct!! - Nexus 4 Q&A, Help & Troubleshooting

Most of us Nexus 4 owners are aware the battery life isn't great, but OK at most. Mine seems to get stuck on 13% then suddenly drop to 1% then die, and when I turn it back on, it will be on 2%, and stay like that for a good hour of moderate/light usage. then fully die. There obviously isn't something right here. is anyone else noticed this problem or something similar? If not, please try this. I hope I ain't the only one with this strange battery!

something similar happened to me yesterday. The battery drained very quickly to 1% and then lasted for nearly 30 minutes of intense usage. I guess the issue is related to the battery calibration.

Glad I am not the only one. must be a way to fix it with an app surely!

Regarding the battery . Have you guys notice any weird behavior when the phone is plugged into USB source? Xplodwild tweeted out the other day that when the phone reaches 100% it begins discharging even when plugged in to USB. Doesn't happen when using AC source.

USB source obviously doesn't provide sufficient power to keep at 100% or it could be a fault that it doesn't lock the power on when it hits 100% so it just stops completely providing power. Very interesting though.

That's how every phone works. If it didn't stop charging at 100% the battery would overheat.

Actually phones normally lock it at 100% so it stays at 100% constantly when plugged in

Battery's not full charging

My X2's battery seems charging in eternity. Have it plugged almost half a day and still is charging. I'm always turning my X2 off when I'm going to charge it, so I can see the battery icon when it's full. But this one's crazy, when I turn on my phone and looked at how many percent that it has been charged...it says 100%. But then again when I turned it off (still plugged to a charger)...it's still is charging.

Same issue as mine. I wonder what's causing this?
dont worry
this is the problem that many of us are facing with.
no way to get rid of. phone jast charges till 100%, and illumination stops , but the status remains charging. but really its stopped. the charger and battery both get cool.
Had anyone of you did try to send it to SE service center to address this issue?
Many times when I charge the phone the % indicater will just stay at whatever it was when I plugged in the charger. If unplugg the charger for a few seconds and reconnect it again the % indicater will update.
It's just one of those bugs.....
l have contact SE about a month ago..still no reply

It's better to leave the phone on when charging, that way the OS itself can control power management.
Really though, don't worry about it... as it has been said... it's just one of those things

This is a question that is very difficult to answer as it depends on which applications you are running and how you use your phone.
Earlier this week I experienced that the battery dropped from 100% in the morning to less than 20% around 5 PM after having used the phone quite frequently throughout the day.
Yesterday I used the phone very little and from 100% battery yesterday morning I'm now down to 59% after 26 hours of use.
If you want your battery to last make sure you:
- turn off the screen when you do not use the phone
- turn off WiFi and Bluetooth
- don't use the radio
- turn of GPS
Maby someone else have more tips on how to get the battery to last.
here issue is not standby of battery-it is simple charging time and unacceptability of x2 to stop charging procedure. it just go on and on with charging(it does not display when it the battery is full it display that it is still charging-even if the phone is on charger more then 10h!!)

Sometimes I can use it all day and still have somewhere around 40% to 60% left at the end of the day. If I don't use it that much, it will maybe drop 10% per day. I have gone 3 days once without needing to swap my battery.
I have a standalone charger and 3 batteries. So I swap out the batteries from there every time it is low. It could be possible that the standalone charger does a better job of charging to full capacity.
EDIT: I also leave my 3G on always!
My battery lasts 3 days,about 30min of talk every day,5-10sms,20-30min of wifi,3g is off,gps not using yet...so that is about that.

Battery Power Drops from 100% to 90% in about 3 mins?

Has anyone else seen this? From 100 to 90% the power just drops almost instantaneously but after 90% its normal.
Already been brought up, a lot.
Apparently when your phone charges up it stops once it reaches ~100% and begins discharging, even though it is still on the charger. People will turn their phone off after a full charge and charge for an additional 20min to an hour before they get another green LED. People have reported much longer battery life when doing this, but it is a pain in the ass.

Ahh interesting. I thought I was running into an old winmo rom flashing issue where if you flashed under 50% battery life you could never charge the device above that point.

Hmm i tried and it acted the same way.
Apparently the HTC models act like older phones did back in the day. What HTC needs to do is put something on the phone face itself when new that says "CHARGE FOR 4 HOURS BEFORE INITIAL POWER ON FOR MAXIMUM BATTERY LIFE."
Once you do this once you dont have to keep doing it. I also powered on my phone the minute I got it and activated it without charging it first and I was seeing this issue until I did a power off charge. The phone runs from 6am to 11pm without an additional charge cycle in the day and that is a huge improvement for me. I was charging the phone twice to three times daily.

[BUG] Full Charge Oddity, Charge to 100%, Unplug to 97%

[Q] Wifi Tether: Subject to $15 T-Mobile Charge?
Curious about this. Currently I'm connected to my laptop for the past 15 min just fine; no alert came up that said I had to get the $15 fee that T-Mobile charges for the "privilege" of tethering on my current plan. Does that mean that an unlocked phone isn't subject to T-Mobile's tampering?
If so, is this the only value for rooting right now? I don't see any other need for root with this phone except if it fools T-Mobile.
Thanks in advance for your answers.
I know there are numerous threads about battery life, but this one isn't about the life itself really.
I can charge my phone to 100%, but when I unplug it, the battery indicator shows 97% right away. I plug it back in, rinse and repeat, and get the same issue. I even tried charging with the phone off.
Ha anyone had luck with using a full 100%?

I see that some people don't get to 100% during the actual charge process, but haven't seen my issue yet. I'll keep looking. So many of these threads...thanks.
Just trying to figure out whether it's worth going back for another phone or battery. What would you do?
Id keep it, there was an article posted in one of the threads stating why phones do this...the N1 did a similar thing where after it charged going from 100-96 percent went really quickly
i would equate it when you buy a 16 gig SD card and it shows as 15.6 gigs
Same thing here... pretty sure it's happening to most people.

Mine did this until I calibrated the battery. Charged it to 100%, then drained it all the way. Charged it back up to 100%, and now not only does the battery last longer, but the percentage seems to go down in a more linear fashion.

Same here, I've done this two nights in a row, but no change.
Thank you for the links, guys. Pretty insightful actually. I've got it charging right now at 99%. As soon as it hits 100%, I'll take it off and see if it drops instantly. I'm guessing it shouldn't as it JUST hit 100%. But we shall see..
Thanks again!
Same issue here afetr the caliberation and all
I really wouldnt worry about it guys, not like magical unicorns are eating your percentages
Well...I mean, it's not something anybody is "worried" about, but it does suck because I use my phone heavily as I'm in the IT field ... so every percentage counts. After I just unplugged, it went to 99% which my N1 did as well. I'm fine with 99%, but 97% seemed a bit low.
Full charge oddity
When the phone has been switched off and charging the phone shows the fully charged icon on screen when charging appears to be done. Battery Indicator Pro displays only a 95% charge when the phone is switched on. The same happens when the phone is on and being usb charged. When 100% charge is shown and the usb cable is removed the charge is then shown as 95%. This does not happen on my other devices running 2.2. They will show 100% or 99%. A device design or 2.3 bug?
Read this whole post:
http://forum.xda-developers.com/showthread.php?t=871051
The epic 4g has this problem. I think its something with samsung. You have to unplug it, plug it back in, let it charge to full again and rinse repeat until its really at 100%
Then reset your battery stats in cwm

As noted in the stickied FAQ and further discussed in the link provided by nxt (Beat me to it!), this is by design folks.
unremarked said:
Q: I unplugged my phone, and my battery dropped from 100% to 95% immediately, or it won't/takes along time to charge past 99%, what gives?
This is by design. Your phone will slow down and eventually stop pulling charge at or slightly greater than ~95% regardless of what your battery indicator says. This is to extend the overall life of the battery, as constant 100% to 0% charge/discharge cycles will cause it to fail prematurely. If you're interested in really pushing it to 100%, you can use a technique that is called "bump charging" and is better detailed here: http://www.androidpolice.com/2010/12...battery-drain/

Weird battery reading
My Nexus S was at about 16% when I put it on the charger then I did a quick reboot and it said it was at 52%. I unplugged it, powered off, pulled the battery, then rebooted and it read 28%. Even that is hard to believe after less then 5 minutes of charging. Has this happened to anyone else?

Charging battery to 100%

If you leave ur wirless tethering on while charging, your battery will charge up to 100% and stay 100 even if you take off the charger.

Charging to 100% will not shorten the battery life if any Lithium Ion or lipo battery, but if you discharge past 5% will kill the battery faster. This I know from using the lipo battery's on my big RC Helicopters and that the ESC's have a low voltage cutoff on them to keep from doing damage to the battery. All lipo batterys are built the same so before someone says it is not the same, YES it is!!!

Already posted, and already shown that it doesn't work...battery still only charges to 96-97%
And there is an issue with the firmware in the Nexus S that prevents it from fully charging to 100% (incorrect voltage cutoff level?). This is NOT a deliberate way to "save" battery life.
Charging to 100% does NOT harm the battery or shorten its life in any way. Li-Ion batteries work best and have a longer total battery life when topped up to 100% regularly.

i believe i heard 2.3.5 will fix this and many other issues we are having.
Another way to fully charge your Nexus S is by switching it off and plug-in it to a wall charger until it finish charging (you will notice that by means of the white battery icon that will show up if you press -just a single touch, do not keep pressing- the power button). Every time I charge my Nexus S this way I get a full 100% battery charge.

ive done this and i never reach 100%. the highest i have gone is 98%.
This is curious. I usually pick my phone in the morning and read some tweets and news before I get up, while the phone is still connected to the charger. When I 1st take it it has about 96-97% but after I use the phone for some time it goes up to 98 or 99%, but never got 100%.
does that 5% really make that much of a difference? maybe it helps the battery to not go to 100%, maybe it doesn't...
but are you really using the battery down to 5% before charging it where it makes that huge of a difference?

guys is better to charge the phone before it is <5% or not?
if you leave the screen on while charging, you can charge it to 100%, i do it a few times a week. as soon as the screen goes off over 95%, it will stop charging, at that point just unplug it, then plug it back in and leave the screen on. itll get to 100%. have patience, itll just takes some time.

[Q] Major Battery Problems with Nexus 4 - Help Please

Backstory: I've had my Nexus 4 since December 2012. I lived in San Francisco using T-Mobile through August 2013, and I've just moved to Sydney. I got a new sim through Vodafone here, and everything went well. Though my battery did drain a bit faster than usual, I employed Greenify and pretty much solved my problems. Fast forward to this weekend, I used my phone heavily all day and turned it off once it hit 2%. After getting back home for the night, I used it heavily while charging and everything battery/power wise and otherwise was behaving as expected. I went to bed with my phone draining and at roughly ~40% (making a guess) and not on the charger. I woke up at ~3AM, put the phone on the charger, and when i woke up at 6AM, it had only charged to 67%. This was my first sign something was wrong as I usually get a full charge in less than 3hrs. Over the course of the day, I monitored my phone and notice that whether on or off it charges extremely slowly as in 6+ hours still doesn't get to 100%. Additionally, using the phone while it's on the charger is net negative on the battery's charge as in it decreases albeit very slowly while using it on the charger.
I had my phone plugged in last night, and took it off the charger at 2AM at 100%. When I woke up at 6:15AM, I took the following screenshots (attached).
You can see that over 4h 15m off the charger and with no use the phone drained 44% with 37% coming from phone idle, 23% from cell standby, and 15% from wi-fi. This seems ridiculous to me. Can anyone help? What kind of troubleshooting can I do? It feels to me like this is hardware related as I get the problems whether the phone is on or off, but I'm not sure. I'm currently rooted and using AOKP Milestone 2. Here's a screenshot from about phone (attached).
Thanks for any help in advance! I'm really hoping to be able to fix this with software changes as I'd hate to have to buy a new phone with the Nexus 5 right around the corner.

Is anything wrong with your battery? If it is in very bad shape, you should probably get a new battery.
I don't know that even excessive wake-locks would cause a phone to charge that slowly, especially a Nexus 4.
Was it on the dedicated wall charger? Have you tried multiple chargers? Multiple wall sockets?

Even though the battery stats isn;t showing the phone as awake, I wonder if there is an errant app causing a wakelock. I would definitely check with better battery stats to see if anything is preventing your phone form sleeping when not in use.

94.64 degree fahrenheit for the battery. Is that high?
edit: Mine says 95 degrees
It seemed that google play services was sucking most of the juice, but this isn't always the case. I decided I was just going to go with flashing a new ROM, but even with USB debugging on and Connect as Media Device checked off in USB Computer Connection, I can't get my computer to recognize my phone via USB. I've tried this with two different cords, multiple ports on my computer, and even with a friend's computer. I'm starting to think my phone has just completely **** itself. Any advice?

your body temperature averages 98.6F. keeping your phone off and in a tight pocket on a warm day could raise the temperature to 95F. so, is 95F high?
Got exactly the same problem, already replaced the battery, but that wasn't the problem. Can t RMA because I'm not on the country Where it has been bought, so I'm really with my hands tied in here.
I already thought it could be the Qualcomm Power manager (IIRC) that is damaged, but that chip is soldered onto the mainboard..
