Hello everyone,
As you have seen from the title my Nexus 7 charges really weak and drains much battery in short time. When I plug the charger, with 12% left, it's like 40% 2 hours later. Even when browsing, beginning with 100%, 1 hour later it's 72%.
Something really odd about my tablet is that the display uses around 90% of the battery. I'm really afraid, because the tablet is really new.
Tablet is rooted.
Android version 4.2.2
1,5 months old
Thanks in advance

Hello Experts,
I received a new nexus 4 and noticed that it takes around 3.5 to 4 hrs for complete charging from 5% to 100%.... is it normal? my other sony xperia seems to be charge in about 1..5 hr
since i am new to Nexus 4, not sure what is the avg charge time and should i call for RMA? Please let me know what is the avg time for charging.
thx

Perfectly normal. You want a nice slow steady charge, especially in a sealed phone. The battery needs to last as long as possible. Fast charging batteries significantly reduces their lifespan. My old Nexus S takes the same amount of time to charge from 5%.. 3-4hrs or so give or take.. I still have the two year old original battery and it holds a charge just as well as it did the day I bought it. Meanwhile my 15 minute charge AA batteries I bought last year lose their charge in a week just sitting on the desk.
Mine is just about the same, but that's under use. If I don't touch the phone, it typically charges to 100% in about an hour.
And if it's through USB.. um.. more like 8 hours to fully charge.
Battery widget reborn (awesome app btw) says my phone usually charges in about 2.5 hours. This is on Qi though not sure about the regular wall charger.
2-2.5 hours for me on usb wall charger and Qi Orb.

From 2 hr 45 min (from around 12-15% juice left), my charge time has reached to 3 hr 30 mins now (i.e. from 1% juice left)... 14% juice wouldn't make such a huge difference so don't really know why it increased..

yes, this is one of the reasons i started this thread to understand what everyone is experiencing.... i called up the google customer support and they are ready to send in a RMA as it appears to be a higher side...
so let me know your thoughts guys...should 3.5 hrs charge time considered high and warrant a RMA? share your thoughts.
^ Hmmm.. I doubt if this would mean anything serious or worth RMA-ing. I can but I won't RMA my device because it's been exceptional so far. I am fairly happy with it and wouldn't want to get it replaced with a defected one.
Its perfectly normal especially from around 5% to 100%.. In my experience if you dont let it get below 20% it usually charges faster. I wouldnt RMA it especially if your phone is perfectly fine in other aspects.
I tried with a different charger yesterday and it took similar time. The charger has same voltage input levels.
You charge 3 hours, for only double the lifetime. How pathetic, actually. I didn't thought that the battery life would be that bad. I can hardly make trough 1 day, if I play some games, make some calls, and use a little bit of internet. On the last charge I got 4Hours of screen on time with 15% left.
Gosh, at least it's fun to use it. :/
I thought the charge time would be long. This morning in class my battery dipped down to 12% as the class was wrapping up. I got back home around between (9:50 and 10am) and started charging my note 2014 while it was powered off. In ~2.5 hours I'm around 55-60%. Personally I don't think this is too bad at all.
What have your experiences been like so far?
Update. I just unplugged it and I'm at 91%. This thing charges much faster than I thought. What were the conditions in which reviewers said it was 7+ hours?
Update: I'm also interested in how long the charge tends to last for you.
mine was ~2.25 hrs from 20% to 80% then ~1.5hrs for 80%100%. the fast charge cycle is pretty decent, it's that last 20% trickle that can feel like it's dragging on. bmw pro says 4:14 for a full 0-100% charge which seems to be in line with my results.
I put mine on the charger at 5% before going to bed. When I got up 5 hours later it was fully charged. Not sure when it reached full charge but definitely less than 5 hours.
From 5% to 100% in 4hours en 45 minutes.At 5% screen on time of 7 hours en 24 minutes!

This occurs with mine as well. It's that 80-100% that takes a while but when I charge it anywhere before that it's pretty fast. Probably helps with the long term battery life. Which I'm fine with.
I'm thinking that review got a bad battery. This happened with my first GN10.1 when it took forever to charge after using it the first weekend.
I swapped it out and the new one charged fairly quickly (considering). This new tablet seems to be just a little longer to charge but not 7 hours.
This has been about my experience too. I was really worried before because a lot of reviews said this tablet takes forever to charge to full. Glad to see that smart-charging mitigates this almost completely since an 80% charge easily gets me through a full day of moderate use.
Mine has been 4.5-5 hours, which is AWESOME!
People expect it to charge as fast as their phone need to realize the battery is much larger! I have had the same experience with a new, bad battery taking longer to charge as well though.
The 1st picture attached is my charge time for one night so far. Using the System Monitor app. Really digging that app. You can even have floating windows that stay on top as you run things.

my charge times are about 4 hours from 5% to 100 with screen on and energy saver, with it off, i go from 5% to 1005 in about 3 hours
As pleasant a surprise the charge time was I must admit that the charge tends to go pretty quickly. I'll post back with specifics when I get a chance to properly mark the times and usage.
Help guys, my battery drains so fast. It charges so fast also drains so fast like 1 hour and 35 mins of usage and its dead. Then when I charge again it instantly goes 40%+ again even though my battery just went 0%. I tried many roms, kernels and chargers. No hope
I have same issue it even sometimes charges very slow and when its on charger and I'm using my phone battery drains.
Is this a problem with battery or my phone?
* I use stock charger and OTG

I have a used Note 3, one year within my posession (I'm thinking this here's 1.5 years old.) I think it's a problem within the BATTERY itself. Fortunately, spares are fairly easy to find and for cheap. I tried another battery and it gave me 3+ hours screen on time consistently no matter the usage when the original battery could barely eke out 2.
So I had this 910C for a while. Still love this phone but recently the stand by time kept decreasing. This was my second battery but I used fast charging, so I thought what the heck, I will just buy a new one.
Well I did, and the stand by time is just as bad. Almost half my battery is gone by the morning, and the battery barely wants to charge as well. (it's like the phone is cold and the charger is also just lukewarm.)
So what the heck?
Is there a known hardware defect on the Note 4 for this?
Even if I could replace the phone (but why when it works great otherwise), I would still like to keep it around as a secondary device.
Any ideas?
Ps.: Now when I was writing this, my phone also got quite hot but the AUKEY portable charger is cold. My percentage was 16-17 and it could not go higher.
Well, after long hours of charge the new battery does show 100%, but when I make a call the phone gets extremely hot. Like it burns my face.
This morning I watched like 5 minutes of Netflix and that ate ~20% of my battery.
The battery does not get hot, is not bulked up, it's very hot around the main chip...
Using latest Samsung OS btw, don't even have root installed atm.
I purchased this tablet brand new maybe 6 months ago and haven't used it that much at all.
Tablet is maybe charged like 10 times total.
I noticed that Screen on time is drastically used from 9 hours when I purchased it (9 hours on wifi) to now only 6 hours (cca like 70 % of use with wifi).
So I thought that the stock charger is reducing the battery capacity because it is quick charger and charging battery with high current which I don't need.
Is it possible quick charger is the issue and making battery in worse condition?
Now I put it to charge over USB 2.0 port which is I think giving only 500 mA.
I never got 10 h of screen on time like on declaration of the tablet.
What is your SOT for this model?

My record is 11 hours using Netflix and Amazon video with 100% Wi-Fi in 48 hours of use. If it's 6 days, about 9 and a half hours. Downloading series and watching the chapters offline, it gives me 12 and a half hours with manual brightness of 70% on average. I am on android 9 and I have no intention of going up to A10 or A11 if it ever arrives. Very happy with my Tab S 5e!
Li's don't like sitting at a full charge especially in high heat. A 50% charge is much better for long idle times. Limiting the top charge to 80% and the max discharge to 20%, preferable 40% will greatly increase the life of the cell.
The capacity lose is most likely permanent.
If any swelling is noticeable replace immediately... fire hazard.
Then something is wrong with my tablet.
My total SOT is around 6 h watching youtube videos.
Is it better to do slow(normal) charge for the health of battery?
