Well... I completely stopped charging my phone with the wall charger and I am now just using either my car charger or USB and i've noticed my phone over the last two days has probably doubled in being able to hold a charge. Today I made approximately 2 or 3 30 minute - 1 hour calls, used the internet approximately 20 times for about 5 minutes each time and used SNESnoid for approximately 1 hour straight and my battery was at 40% after a 10 hour work day, not too shabby. Not to mention I also don't get that annoying 10% drop within 10 minutes of unplugging the phone anymore
I've seen a ton of other battery tip's but I've yet to see any actually say stop using a wall charger all together. Here's to hoping this helps someone
Lol thanks for the tip. I highly doubt this is anymore then a placebo but good luck to whoever tries it. Not calling you OP I am just finding it hard to believe.
Furthermore, have you tried reseting your battery stats. I mean the initial 100-90 percent drop you are calling to quick sounds like its the fault of bad battery stats. If you need a link to how to reset your battery PM me only because I might not check back to this post lol.

Hmmm... I don't think that USB/Wall would actually make a overall difference in battery life but it could be that it doesn't "idle the charging" when you hit close to a full charge. So you're probably just getting the extra 5-10% that you mentioned.

I know for a fact im getting the initial 10% but I looked at my battery today at 12:40 tonight before leaving work thinking "ahh crap I haven't charged it it's got to be at, at least 5-15% and nope, it was exactly 39%, I was amazed. Talked to a girl for about 40 minutes on my drive home, talked to another friend for 5 and battery dropped to 35%
I've noticed this as well. Days that I've only used my moto car charger, the battery (even the cheap ebay ones) seem to hold the charge better, which I thought was strange, because you would think it would be a worse -maybe equal- change.
Charges more slowly and fills up more?

That's my theory
This is the case with most batteries, and I thought it was common knowledge with Li-ion. The lower the current you charge with, the better the charge.
Using the higher amperage wall charger lets you hit the voltage peak quicker but, the topping charge will take longer. A lot of car chargers are just as high amperage as wall chargers.
Other things you can do to try maintain the capacity of the battery over the course of its life:
-NEVER let it get hot (whether from heavy usage or keeping it in a hot car or the sun)
-never deep cycle (totally kill the battery)
-try to keep it between 40 - 60% charge for most of its life (Li-ion batteries do not like being at full charge or no charge)
Doing any of these things once will not destroy the battery, but by the 500th charge cycle, you can bet your ass it will.

Sounds like my kind of job! Seriously, I use USB (through a laptop) and car chargers almost exclusively and I have no real complaints about battery life. And by that I mean it gets me through the day, which is all I've come to expect from phones for the past few years. But I did happen to use a wall charger last night, and I have JuicePlotter active, so I did some checking.
Comparing my last overnight charge using my laptop's USB to last night's charge through a wall adapter, I found that the charging was actually faster through the laptop. I see that the charge tends to drop off as it approaches 100%, so I took pairs of points from uniform sections of each plot for my comparison:
Laptop USB:
44% to 82% in 41 minutes = 0.927% / min
Wall:
63% to 91% in 37 minutes = 0.757% / min

Hah, yeah my job is pretty amazing sometimes but I have def quit using the wall charger (unless I absolutely have nothing else around)
As far as for droiddev... this is my first phone where charging it from different devices gives me different results. I don't see where it would be common sense, Li-ion batteries are not supposed to not have these memory leak/hold issues like past batteries. A charge is a charge to li-ion batteries, but not in this case.

Not sure what you mean, but you will get the most life out of your battery by charging it short spurts at a time over USB. Read the article I linked to and you will see what I mean, but you can get the best charge into your battery by slowly ramping up in steps with a low current charger.
Just wondering, how long does it take you guys to fully charge (From anything below 20% to 100%) your nexus 7? Because I've seen a few posts about battery related problems, and personally I think mine chargers slower than it should.
Also, when I use a wire to extend the charger, it's as if it wont charge, for it to fully charge i'd have to leave it on for hours without use, Since they're aren't any plugs where I'd usually sit to use it, I need to move somewhere else cause the wire is quite small.
For example, I've had it on charge since 2PM today, when I plugged it in it was at 14% battery, now (4:20 PM) it's at 63%. This has been without use, just sitting there charging. Plugged in via the charger and wire that come with it, to an extension with 3 other plugs in it.
I received my N7 with about 40% charge and it seemed like it took a really long time on that first full charge. It has been better since. I have heard if you are not using the original cable for the N7, it will dramatically increase the time it takes to charge and it won't show the charging icon. The supplied cable is USB 3 and your other cables are most likely USB 2. You might want to buy a 6 foot or 2 meter USB 3 cable for convenience. Also, use the original 2 amp charger it came with.

Well, that explains why the extender doesn't work, but I haven't been using that to charge it since I noticed it slowed it down allot. I've only been using the stuff it comes with ever since I noticed that. Still VERY slow though, it's only just reached 96% since starting charging it at 2am. so it's taken 5 hours to get from 14% to 96%, pretty sure this isn't right.
I've collected some data on N7 charging and cables issues here.
http://forum.xda-developers.com/showpost.php?p=29983624
My completely drained N7 (<1%) takes approximately 3 hours and 49 minutes to completely charge it (N7 powered off during charging).

And good to know it isn't a problem with my nexus I suppose.

OEM charger and OEM cable.
I've had this problems about a week after I got my N7.
The Micro USB cable that came shipped with my tablet charged it while I was using it for about a week.
After that week, the battery would just plateau around whatever percentage I had before charging.
A few days later, it wouldn't charge fast enough and the battery percentage just dropped.
I switched to a First Gen Nook Micro USB cable, which worked like a charm.
Up until now...
The charge seems to be close to plateauing again, because it charged a good 3% every 10 minutes, now I barely get 10% every hour.
What the hell is going on?
I spend $250 on something I expect to at least run on AC without any problems.
Sorry the post is long, and thank you all tremendously for your help.

a few people have had this prob , i think i sometimes have it, as if i use a certain usb charger it charges to 100% in about 2.5 hours, with the other one it'll take 3-4 hours to reach 100%.
im not sure but i think there is a app on market to show what recharge voltage your getting while plugged in, i cant remember the name thou srry:crying:
Why do you think the Nook wire stopped working though?
It just seems odd that both wires worked at one point, but slowly stopped working...
Then logic would tell me that it's not in fact related to what cable you are using, but a problem with either the battery itself or the main board. First thing I would do is let the battery die, pop the back cover off, unplug the battery, let it sit for a while, then charge it back up. That may or may not solve the problem, but it's worth trying.

Anyone have concerns about using the turbo charger?
It works great. Took a shower while charging and went from 14% to around 70%. It does however get pretty warm which I worry could adversely affect the lifespan of the battery.

Wow, how long was your shower? I went from 0% to about 15% in 15 minutes. Mine also got pretty warm, but assuming the battery does last for 48 hrs, 15% should last just under 8 hrs. We'll see how it works though.
Haha anyone look at the specs on the charger?
My old peepers need a magnifying glass but I noticed three modes with different voltages.
It goes up to 12V out at 1.2A
I don't think I will be putting this on another device. If the switcher gets confused and applies 12V to a standard 5V USB device, something very bad will most likely happen!

I noticed the phone getting a little warm while on the turbo charger as well. Also, found out last night that it does not matter what cable you use, it still does a turbo charge with any cable. Last thing I found out was that the turbo charger will turbo charge a note 4 as well and the samsung advanced charger (their version of the turbo charge) will turbo charge my phone too.

So you've observed that "motorola turbo charge" is just a rebranding of "qualcomm quick charge"....
It does heat the phone up a bit, left on charger for about ten minutes went from 45 to 65 percent in no time.

How long is it taking everyone for a full charge? Also last it went from 1% - %25 took about 30min is that normal for Turbo?
Can't put it down to charge! I'm letting it gain about ten percentage points before I unplug and play.
It does cool down rather fast.
The nylon isn't as grippy as I first thought, wasn't planning on a case but it might be in the cards, too bad because the turbo is really sexy naked!

Mine took 1 hour 55 minutes to go from 22% to 100%, with a few screen wakes in there for a couple texts that came in. It went from 22% to 44% in about 20 minutes. Mine got pretty warm, but once it hit ~75% it started cooling down, and the charge rate dropped, as it should.
In terms of being worried, a faster charge time from higher voltage is actually good for a lithium battery. The extra volts allows the charge to penetrate deeper, quicker, and more completely saturate the entire battery cell. Will this generate increased heat? Yes, of course. But the battery is going to have a thermal shut off built in to it that prevents any damage from occurring, and in general our idea of 'hot' is far bellow the batteries' idea of 'hot'.
Not too wooried
I have been charging my Droid Razr Maxx since I got it with the ASUS charger for my Nexus 7. It made a big difference in charging times for me. Before purchasing the Turbo, my battery life was still lasting 2 to 3 days with normal use. I doubt this technology is causing the battery to degrade at a fast enough rate for any of us to notice.
Looking at the turbo charger, it's not simply a high output charger like you get on some phones, such as the 2A chargers, but it outputs at almost double the voltage as well, 9V vs 5V.

Hah. I should clarify. My intent was to let it charge while I shower but I tend to get caught up watching youtube or looking at reddit before I shower. The total time on charger was 35-40 minutes.
Mine charges at about 1% per minute. I only got to charge it once though so maybe the battery needs to be calibrated or whatever.
Phone started at 50% when I purchased it. Ran with HEAVY usage until about 7:30. Put it on charger with 4% battery remaining. At ~9:15 it was fully charged. More heavy usage until ~Midnight, battery was at 60%. Woke up with 55%, drained it to 43%, threw it on charge for ~20 minutes and it was at 67%. Low usage since, and its at 60%. So theres that.

Haha, yes. I just couldn't remember the name.
Mine took approx 7 hours to complete a charge. Is this normal?
After few months of using this phone, i recently tried turning off fast charge, just because. However i was shocked to see it charges way too slow.
The fast charging works fine, however. Around 1h 30mins or so. I use the stock charger that came with the phone.
Would like to hear how long yours took to fully charge, and whether i should be worried?
P/s. this is my first post here. I've searched with multiple keywords but no results of the standard charging time, so if there's an answered thread, please drop the link.
Thanks in advance,

This is also the same here. What wonders me if why can a cheap (7$) car charger which is 2.1A charge the phone 3-4 times faster than the original charger (both without fast charging)?

There are 3 charging times:
- 1.5h with Quick Charge enabled
- 2h with a good USB 2A cable and stock charger (I am using the Amazon Kindle Fire 2A cable and the stock charger and I get 2h time with Quick Charge disabled)
- 7h with poor quality cables and/or less than 2A chargers.

7 hours? That's ridiculous. My S7 edge charges in 2 hours without fast charging. Never used fast charging, so don't know how much time that takes.
Most probably there's a fault in your cable. Take it to Samsung Service center and get it replaced.
