Ok, this whole bump charging thing pisses me off. My phone should just charge, I shouldn't need to spend hours every morning bump charging it. I've read that others have found work arounds that seemed to work for them - the only thing that's fixed the rapid drain rate in the start of the day (which refers of course to the lack of a full charge) has been daily bump charging. I've read about people using Christmas light timers to do this, but this is a bit more...robust. I've tried something new that seems to be, at least for me, a permanent solution.
1. Purchase something like this. There may be other timers that would work as well.
2. Plug your HTC charger into the timer.
3. Set the timer to cut the power off at, say, 4:00AM (this was a good time for me based on when I wake up for work).
4. Set it to turn power back on one minute later, at 4:01AM.
5. Set it to turn power off again at 4:31AM (my bump charging usually takes 30 minutes per cycle)
6. Set it to turn the power back on a minute later at 4:32AM.
7. And so on and so forth for a total of about 10 cycles (this is what works best for my Dinc, at least)
8. Turn your phone off when you go to bed.
8a. If anyone can figure out a way to auto-power off at around 4:00am, this would work even better. Power Off 1.1 wouldn't work on my SkyRaider Dinc.
9. Plug your phone in.
10. If you programmed the timer correctly, your phone should be fully bump charged at least 10 cycles by the time you wake up! Power on your phone and GO!
I'm interested to find out if others have tried this method. So far it's working wonders for my battery life. Comments welcomed.
Thanks for this post, creative solutions like this one are always nice.
HTC needs to get it together and finally fix this issue. It's starting to piss me off especially in the morning when i have to turn my phone off.

Curious as to how this is an os problem when the incredible is the only one that has it. Also, i wonder how a phone that charges through an os can charge while turned off... its a physical charger problem, not os.
The OS shuts off charging too early. But, its HTC phones in general, from what I've read. Bump charging has been around longer than the Dinc.

but from googling I see majority of the problems come HTC devices, so it is prob a os to hardward issue, or a complete software issue that has been addressed towards HTC... After digging around looks like the G1 had this problem also.
So who knows.
Honestly, my goal wasn't to inspire debate. Just wanted to offer some advice that may help others. If it helps an EVO user or a G1 user, all the better.
FWIW, it is just how the phone works. My Samsung Omnia charged the same way.
I simply let it charge overnight. When I get up in the morning I check my email or whatever and then put the phone back on the charger while I get ready for work. I leave for the day with a fully-charged battery. No muss, no fuss.
What's the big deal?

I suppose I'm just neurotic in that, when I wake up to a phone I plugged in the night before, I want the damn thing to be charged. With three children running around, two in diapers, EVERYTHING is muss and fuss. That's why I posted this solution that works for me. If you don't find it necessary for your circumstances, I'm jealous.
Would clearing the battery stats after bump charging help it get a better charge even when not bump charging?

My Moto Droid didn't do this. In fact, you couldn't charge it with it off.
Nor did my Omnia.
I have an easier solution which works perfectly:
Power the phone off
Charge overnight while I sleep
Power it back on in the morning
That's it. The issue is that the phone doesn't fully charge unless it is powered off. Bumping doesn't do anything special.
Even when it is powered off, if you unplug it and plug it back in you can get around another good hour or so of charging. I turn my phone off at night but bump it when i wake up in the middle of the night because it always charges for at least another thirty minutes.

Mmmm yea I am going to have to strongly disagree...
Actually, not true (about it being the Incredible only). I have an HTC Imagio also (my previous phone) which just happens to have the same battery and it had the same issue. If I charged the phone fully, unplugged the charger, turned off the phone and plugged it back in, the orange light stayed on for quite some time before turning green again.
I'm not saying it's a totally a hardware issue (something to do with the charging circuitry) but I think it's a combination of that in conjunction with the O/S. Android defintely seems to drain the battery a heck of a lot faster than WINMO6.5 did (as proven by my friend who has an HD2 and is dual booting 6.5 and Android. He's found that WINMO 6.5 lasts at least 5 hours or more than Android).
So ultimately, I think HTC needs to look into either A) the quality of these batteries, B) their charging circuitry, C) Both, and the folks at Google need to get to work on their power management logic and algorithms.

I've seen the same results that Amin did doing this whole "Bump" thing vs. just charging with the phone off, unplugging, and plugging back in. I've seen the same results on another HTC phone as well that was a non-android phone.
If you get a set of lithium AA batteries and get a charger, you can test how this is SUPPOSED to work. If you charge the AA's fully, take them out of the charger, then put them back in, you might see the light orange for maybe a minute or so before the charger realizes that the battries are full.
The HTC phones don't seem to do this. They seem to think the batteries are partially drained.

If you charge while off and unplug and replug, you may get some more orange light time. My concern isn't whether I can make the light go orange, it's battery life. What I have observed is that if I charge to full with the phone off, I get better battery life than if I charge to full with it on. None of the other factors (unplugging, replugging, etc) seems to make much difference.
Suggested 18 hours of charging - BY AN HTC REP!!!
Ok - For your amusement, check out some these emails (link below) that people recieved from tech support staff at HTC. In one of the emails, the support rep suggested 18 hours of charging using a modified "bump-charge" technique.
Are you freaking kidding me?!?!?
http://www.incredibleforum.com/foru...scussion/1777-htc-confirms-battery-trick.html
I just bought a HTC TP2 battery charger on ebay for $5 and 2 1500mah TP2 batteries for another $5 a piece and charge one while I use the other. Almost never use the stock battery and get tons of life on the TP2 batteries. Easier than this bump stuff.
I usually just carry the fully charged stock in my pocket. Just in case I am in a low signal area all day.

Has anyone experienced this issue, seems as tho when I charge my battery to 100% it takes less then 30m before it discharges to 92-92%.
This is happening with the original battery and the Seidio extended battery that I have.
Is there a fix for this, or is this something I should call VZW about. A lot of people at androidforums have been having the same issue.

Your battery stats are miscalculated. You need a calibration procedure. Replacing the phone might fix the problem, but if your battery charging habits don't change it'll happen again, unless HTC feels like changing their battery calibration algorithm, and there's no need to wait for that. Any laptap manufacturer will have a good how-to on li-ion battery calibration.
theres no way all the phones are bad, alot of people have this issue that have this phone. i dont think its bad hardware, chances are if i get a new battery its going to do the same thing. im gonna order an extended battery anyways soon so we will see.

I am having the same issue with an extended battery. It's the way the phone is charging the battery. Is everyone just accepting this as is or is not everyone having the same issue. I want to know if I should replace the phone or not...
I completely discharged my battery last night, turned it off, and fully charged it while it was off. Now the first 10% seems a lot more resilient then before. I just hope I don't have to do this every night. I don't have a land line and it sucks having to turn it off just to charge it.
good to see this post, i to have a htc touch hd, and have problems with batteries, ive bought 2 new batteries from ebay.
and seem to get vary results, its as if mobile is showing 100% but the battery is only 40% charged.
charged one last night finished at 12pm and battery was saying it was flat at 7am !
the orginal htc does seem to last longer, but obvisily there is a issue with the phone itself, if it needs reset or something?

Replacing the phone is not necessary. It's actually the OS that cuts the charge short of full. The OS "thinks" the battery is full,thus stopping the charge. Completely drain the battery, then plug it in,leaving the phone on. Let it fully charge while it's on - when the LED indicator is green,and the battery is "full" - while still plugged in, power phone off,and you'll notice the indicator will turn red again,charging the phone for about another half hour or so. That will give you a true full charge.
Days later...and running Froyo, and still battery problems
I'm running Froyo now...battery light green and indicating 100%...and I power off the phone... It has been charging 25 minutes now and still charging. Didn't they(?) say that this had been fixed in the latest ROMs. I'm running Sky Raider's 2.01. Is it just me?
Do I need to erase my battery stats from within ClockworkMod Recovery? I haven't done this because it warns that this cannot be undone. That sounded too scary for me to try.

its a problem with the chargers. youll see if you charge with an external battery charger or a vzw car charger, the phone will charge fine. htc screwed something up with the "trickle" function in the incredible stock chargers. as soon as the LED turns green, the charger shuts off and almost siphons charge from the battery in order to prevent overcharging, which drains the battery to about 95%, but the battery will still show its at 100. ive done the battery stats clear several times and this problem persists even if i leave the phone on the charger for more than a minute after LED turns green, even when phone is turned off. at times the charger doesnt even charge the phone all the way, which is why you can charge completely, unplug, plug it back in and light is red again and takes a few more minutes to charge. both are caused by an "overcharge protection" feature built in to just about every charger these days, but gone horribly wrong in these chargers.

I can tell you it doesn't have anything to do with the chargers. I have this problem while the phone is turned on whether I plug it into my Computer, original charger, off brand car charger, usb car charger, usb cable from the lg ally, or the OEM lg ally charger. it has everything to do with HTCs software on the phone. it is using two different ways to charge the battery, one while the phone is on and in use (that uses HTCs software/algorithm), and one while the phone is turned off(uses the batteries overcharge protection circuit).
jeeeeezz
I have tried everything, I tried resetting / removing the battery stats etc. Nothing works...Its useless ppl...have to wait for a fix from HTC. Which bring my question, does anyone know when or if this is planned to be fixed?
That's right... For some stupid reason, our phones don't detect when the battery is ACTUALLY full. Getting annoyed with the having to charge my phone twice a day, I stuck my battery in my old Touch Pro 2 (left it powered off) and plugged it in... It took about 5 hours for it to fully charge and I let it sit for another hour.
I took it off the charger at 11AM... It is now 11PM and I'm at 68% and I've been doing more browsing and downloading than usual. Previously, I would have hit 20% by now and had to plug in the charger.
Once you charge the battery in this manner once, it should be fine from there because the cells have been fully charged for the first time. As long as you don't drain the device completely, you shouldn't run into battery issues.
Ordered a multi-function battery charge and two aftermarket TP2 "1500mAh" batteries from eBay, all for $11, hopefully they're good
I've been pounding the hell out of this thing today... I've racked up 8 hours of "active" usage... so actually I've used my phone more than normal.
The first clue for me was the fact that my battery didn't drop from 100% to 90% in five minutes like it was before... It would usually drop to 80 within an hour, even on standby...
It was at 92% when I got to work at noon.
Unreal, I never thought I would search ebay for a phone with a BAD esn
What I think is unreal is that our 2010 devices can't do something other devices have been able to do since 2006... AT LEAST 2006...
I'm running fresh .3 and I've had the phone unplugged for 1d 0h 15m and still have 30% left... so I don't have an issue with the battery at all.

I have two of these chargers and 4 batteries. I keep two at work and two at home.
These chargers top the battery completely off. I can take a battery that is "fully charged" in the phone and put it in the charger and it will still need 20-30 minutes of charging. The batteries off the charger will stay at 100% for up to 20 minutes, the ones charged in the phone plunge within 1 minute for me.
I really hope this issue can be fixed with a software update. Charging once a day is one thing, but having to take the cover off, battery out and reboot every morning is not acceptable. Not to mention that I rely on my phone while it is charging for emergency calls.

AFAIK it affects all HTC Android devices. HTC is lazy. Anyway I even put my old TP battery which hasn't been charged for at least 6 months in and charged it with the TP. It appears the first 5% is dead but it is still kicking ass and taking names over the charge I get from the evo.

Your battery was probably charged to capacity before they sold you the phone. Once a lithium ion battery has been charged to 100% it maintains its charge unless you screw it up by running it down to empty a few times. The problem is that for whatever reason HTC didn't see fit to charge all batteries to their max first even full well knowing that they won't get conditioned properly by the phone.

I did too, but think mine is defective. The batteries are pretty good for backup purposes and do their job. My wall charger sucked though. I had a Droid Eris hooked up via USB and a battery on the charger. After about an hour and a half, the Eris charged fine, but the battery was like at 30%.
Now the deal breaker is when I got home. I tried to charge a battery and my EVO via USB. When ever I hooked up the USB my phone litterally lagged almost would freeze to a point. I removed the USB cable and phone worked fine. So in all my charger sucked and can charge the battery but really slow.
I ended up just charging the batteries with the OEM charger and EVO turned off.

Actually i was talking about putting your evo battery IN a touch pro 2 in order to charge all the cells.
So this is the reason why the EVO appears to be charging its battery so fast. I plugged it in, and it takes less than an hour to start beeping "I'm full."
......Because it's not really full.
That would explain why I was about to sleep, the EVO was charged, and I got an email, so it kept beeping every 10 minutes or so. which was annoying. I had to unplug it so I could sleep. I slept only 7 hours, and I heard the phone on the little table beeping again like crazy in the morning. I checked what it wanted, and it was the super warning that the battery was about to die.
No use at all in 7 hours, and the battery went from "fully" charged to almost ZERO.
I was almost crying of laughter. I just thought what a piece of junk. Hopefully I'm wrong.

Now, let's watch the soccer game, let's see how the USA does.
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.

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.
Don't charge your phone overnight! When it gets really low, slap it on the charger for a couple hours until you've got 85-90%. Unplug and enjoy fantastic battery life. I have gotten about double normal battery life (approximately 48 hours) using this method. I'm on CM6.1, mind you, so it may be some quirk with the ROM.

Ive been saying this for a while. I charge up my phone to about 96% and i let it go till almost 5% before i throw it back on the charge. That usually gives me 12 to 18 hours. A lot of people tend to get "battery panic" and throw it on soon as they see it draining a bit. Just leave it alone.
I charge on a wall charger. I have three batteries and change daily. I get 22-24 hours and 5-6 hours of hard use.

Here are my observations:
The Evo seems to have a peculiar way of using external power. Once the battery reaches full-charge the external power apparently gets shut off and the phone operates on battery power until the battery level drops to somewhere around 85-90%. Then the charging current switches back on until the battery level reaches 100% again and the process repeats itself. This differs from more conventional scenarios where the phone actually runs on the external power (rather than the battery) once the battery reaches full charge.
I came to this conclusion while playing with my Evo while it was plugged into the charger. First I noticed that the charging light would cycle from green to amber and back every so often. Then I noticed that the battery level indicator would drop even while the charger was plugged in.
So I started checking my battery level in the morning before I removed the phone from the charging dock and discovered that it was rarely at 100%. I'm convinced that the phone does get charged to 100% when I put it on the charging cradle, but then it sits there running off of the battery until it drops to that magic ~85-90% level and the charging current is reestablished.
But a typical night on the charger isn't enough time for the battery level to drop enough to re-start the charging current and if I come along and just grab the phone, I'm starting my day with a battery which isn't completely charged. In my case, the only time this doesn't happen is if my day ends real late and the next morning starts real early.
Once I had a good idea of what was going on, coming up with a work-around was simple: One of the first things I do when I get up in the morning is look at the charging indicator on the phone. If it's amber I do nothing because the phone is already in charging mode. If it's green I remove the phone from the cradle for a moment and put it right back on. Most of the time the indicator will switch from green to amber when I do that, but if it doesn't I'll go online and read the news or something for a few minutes before I put the phone back on the cradle.
Either way, the phone will then charge for 30 minutes or less before the indicator goes green again. By then I'm done with my morning routine and ready to face the day, and when I grab the phone it's fully charged.
My Evo is out-of-the-box stock (for now). It's a hardware version 0003 and has firmware v. 3.29.651.5. I typically leave my Bluetooth turned on all the time, but I leave 4G, WIFI, and the GPS turned off unless I need 'em. My typical daily routine involves several phone calls, some email downloads and uploads, some incidental web browsing, and some geocaching if a new cache is published within a few miles. As long as I stick with that typical routine, my battery is always in the 40-50% range when I put the phone back into the cradle for the night. Of course if I use the phone more it discharges the battery more, but I'm set up to charge it at home, at work, and in the car.
Now despite everything I've posted here, I can't imagine any practical reason to not top off the battery whenever it's convenient. Letting the battery run down before you charge it doesn't have any effect on how long a full charge will run the phone. In fact, it will actually reduce the number of charge-discharge cycles that your battery can provide before it starts losing capacity. I don't want to type it all again, but if you're interested you can CLICK HERE if you'd like to learn more about LiPo battery characteristics and maintenance.

the evo charges to 100% then cycles to 90% then back to 100% so that it does not explode from over heating thats why when you grab your phone in the morning it might say 93% rather than 100% i dont mind though cause i dont want my phone to blow up

I'm a lot more inclined to believe that it's either an engineering error or a half-baked idea with undesirable consequences. The reason I say that is I've had countless other cell phones and consumer electronics devices which used LiPo batteries for power, yet the Evo is the first device that I'm aware of which operates like that. The rest will stop charging when the batteries are fully charged, but they'll continue to use the external power to run the device as long as it's plugged in.

I think the purpose is to prolong the battery life so it doesn't charge again every time it drops to 99%.

Apparently my point is just blowing right past everyone.
For most modern consumer electronics devices the charger can serve at least two functions which are charge the battery and run the device. These functions are remotely related by virtue of the fact that the power comes from the same source, but the functions themselves are typically quite independent of each other. In other words, most devices can run off the charger's power regardless of whether the battery is being charged or not, and when the device is running on the charger, it's not drawing power from the battery.
But it appears that the Evo doesn't do things that way. In essence, it seems like the Evo is hard-wired to the battery and the charger is incapable of independently powering the device when it's not charging the battery. So the battery reaches full charge, the charging circuit shuts off, and the phone starts draining the battery despite the fact that the charger is still connected. Once the battery drains to ~85-90% the charging circuit kicks back on, the battery gets charged back to 100%, and the whole process repeats itself.
Consequently it's a crapshoot whether our Evos will be fully-charged when we take them off of the charger unless we take some additional steps. I can deal with those extra steps, but I can't come up with any practical reason why we should have to. No matter how long I analyze the situation, I can't see any benefit to doing things that way except, perhaps, to save on manufacturing costs. All I can come up with are annoying extra steps and unnecessary battery charge-discharge cycles, and I can't grasp how those benefit anyone.
I see that you and I have carried some of the same phones in the past, TheBiles (Sanyo 8300, Treo 650, Hero) and I don't remember any of those phones coming off a charger with anything less than a full charge unless I interrupted the charge cycle. In fact, I'm convinced that no phone that I've ever carried has had this problem. The Evo is the very first one which is why I suspect some folks at HTC are quietly saying oopsie.

Pete, I'm not convinced most smart phones actually power themselves off of the wallcharger when plugged in as you seem to think. I have no real evidence to back this up, though - other than my own observations.
I will say that the EVO's method isn't as isolated as you seem to think. For example, the Palm Pre which I owned for a year previous to the EVO operates in the exact same manner.
The Pre would hit 100%, stop charging, operate on battery power until it dropped to 95%, then charge from 95 back to 100. The EVO, however, drops down to 90 before it starts the charge cycle again. This is probably better for the battery - but more confusing from a user perspective.
This might be your first phone that operates this way, but it certainly isn't unique to smartphones or HTC.

I completely agree. This is clearly going on, and I'm surprised more people don't talk about it. I put Cyanogen on mine the day I got it, so I thought that was the issue, but I went back to stock (for a day) and it did the same thing. The light goes off after 90% and it stops charging at 100% until it drops below 90%. I also agree that it doesn't seem to serve a usable purpose, and seems to be a design flaw.
I'm still very happy with the phone, but when battery life is this important, that's kind of a big deal.

I had two Pres, and both had the battery % mod on them. I used to set them on my touchstone at work all day long, and I would take them off periodically. My battery drained so bad I could lose 30% in an hour with light use. If I ever took it off the touchstone when it wasn't at 100%, it was only because it got too low and wasn't at 100% yet. I noticed this on day one with my EVO, and never noticed a single issue anything like this on my Pre.
I'm not saying it wasn't there, I'm saying I NEVER noticed this. As far as I knew, it charged to 100% and then ran off the plug, or at least that's what I assumed.
this is a strange thread for xda; competent, fully formed sentences. civilized banter. it's nice!
on topic though, i have noticed and came to this conclusion independently a couple months ago. it's kind of irritating - i hate how cheap manufacturers can be sometimes (all the time).

Hey, I've seen MUCH worse forums. Try Anandtech sometimes. Some great threads there, and a ton of awful.
I feel like HTC is just not that company that cuts corners. I think this might have been a real attempt to make something work well - or better - but in my opinion it failed miserably.

You may not have noticed it, but I can guarantee you the Pre charged as I described. It was a "crapshoot" when you pulled it off the charger as to where you actually were in the charge. You could be anywhere from 95 - 100. Of course, the Pre would always show 100%, just as the EVO does.
Because the Pre's battery was smaller, WebOS was more battery hungry than Android, and the fact that it only cycled down to 95 instead of 90 like the EVO are all reasons why you might not have noticed it, but it was there.

Why would it be better for the battery? They may be partial charge-discharge cycles but they're cycles nonetheless and the Lithium Polymer cell chemistry is only capable of so many of 'em before it starts to degrade. Short cycles are easier on it than full cycles, but they all take a toll.
I currently have something like 40 LiPo packs that range from dinky little 35mAh single-cell micro batteries to a couple of 10S (37V) 5000mAh packs. I use them in my R/C planes and helicopters, communications gear, and electronics projects and I've used up and disposed of many times that over the years. I even had to build my own packs and chargers when I first started using them because the cells were experimental and there wasn't anything commercially available yet.
And I survived all that without having a single LiPo fire (that I didn't deliberately trigger) and I attribute that to the fact that I've been rabid about learning everything I can about the technology and the use and care of the batteries.
And I'm unaware of any benefit that can be gained from unnecessarily cycling LiPo batteries regardless of how small the cycles are.

My predominant theory is that HTC has erred on the side of caution on the advice of their legal department. LiPo cells can easily become little firebombs if they're mistreated and the overwhelming majority of "events" occur during a charge cycle. Search YouTube for lipo fire and you'll find pages and pages of examples, but beware:
You may not want to carry yer phone in yer pocket right next to yer cojones anymore after you do.

Having the wall battery charger solves this issue. The wall charger will charge the battery to full capacity.
It also allows me to test battery life on roms/kernels as accurately as possible. Only time I connect the phone to USB is when I need to move files.

When you say wall charger, do you mean one that you have to remove the battery from the phone and insert it in the charger?
Pete the Curious
Just wanted to say that there have been many discussions on this here at xda, I guess most of us just deal with it.
What I do is charge externaly with a cheap Chinese charger that Came with two batteries that work great.
Every since I made this move I haven't looked back. My battery life is great now, 24 plus hrs per charge. Sometimes I go close to 40 hrs, and I use Bluetooth, have GPS and WiFi ways on. In fact I don't cut any corners, no under clocking either.

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?

Try factory reset if not battery might be taking a dump

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.

The problem is that it's not only discharging quickly while on but charging slowly while off.

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..
