I think nobody asked this question before since I didn't find it even loking in Google
Since I got mi Desire I realised that not every charger works for it, I have an USB charger that went with a bluetooth dongle I bought (with same specs) but seems to be a lie because the battery keeps draining when plugged in, but that's not the problem I actually have.
My original HTC charger broke after three weeks of normal use , since there are no HTC stores in my country I went to an Apple store and bought and Iphone charger wich has the same specs as the broken stock one (Output 5V 1A). The problem is that sometimes when I plug the phone (usualy I charge my phone overnight), the screen becomes buggy, sometimes not responsive and sometimes over responsive (eg. if I click on an icon to move it into the home screen, it responds as if I clicked that icon several times very quickly). At first I thougt it was a ROM issue, but at this moment I already tried LeeDroid, OpenDesire and now I'm on teppic74's rooted Froyo and had similar issues in everyone of them. It's not really a mind breaker since I am ussually sleeping while charging, but I wonder if I'm not killing the battery or causing any kind of damage to the phone.
Can anybody give me a hand on this?
Thanks
Why not just order a charger online?
I don't know if it hurts the phone or the battery.
But if my screen went super-laggy and over-responsive by charging it..
I'd throw the charger out.
Already ordered, but I was wondering if someone happened to know a technical reason for this to happen, the phone doesn't overheat and the charging process works as a charm, the only issue is the screen wich sometimes behaves perfectly normal
Guess I will give the charger to any iphone owner when I get the original one (I have to buy in the UK store.. totally overseas)
My phone does the same thing if I use a PS3 charger (Just the usb to wall socket part). When I was in a phone shop, I noticed their Desire HD that was on display did the same thing. From what I can gather, it doesn't do any damage and happens with a lot of aftermarket chargers. Don't take my word for that though, hope I shed some light
Hello
Have same problem with my recently buyed HTC Desire while charging with non-original charger (from Nokia).
First time I'm worried about phone, but after reading charger's characteristics I found some difference in power.
So I think while phone charging it's receives less power than needed for normal work.
I am REALLY unhappy with this phone. Aside from the poor signal and other issues well known to the Nexus, I now have a phone that has a charging problem. Sometimes when I plug the phone in, it does not recognize that it is plugged in and will not charge. This is not an issue in itself, because if I unplug and plug back in a few times it will eventually charge. The big problem is when it is NOT plugged in. The phone will often switch between charging and not charging on the battery indicator.... even though it is NOT plugged in.
I read up on this and found that... shocker.. this is just one more issue plaguing Nexus owners. The real problem for me is that everytime the phone switches from thinking it is charging to not charging, about every two seconds mostly, the screen comes on. This results in the screen constantly going on an off and the battery draining extremely fast. It is 8:17 am, and I unplugged the phone at 6:40 this morning. In less than an hour and a half, the battery has fallen to 38% and I have not used the phone at all today. It is sitting on my desk, flashing like a disco club.
I have searched but have only found an option to keep the phone ON while charging. Is there an option or app available that will prevent the screen from lighting everytime it thinks I have plugged it in to charge? I am rooted, so any option known would be helpful.
I cannot wait to throw this thing in the garbage, but I am not happy with any of the other options currently available. I like the look of the Galaxy S3 but the Gnex has left a bad taste in my mouth for Samsung... it was my first Samsung phone and I'm not sure if I should judge the product line on all the problems I have had with this phone. I loved the HTC Incredible it just got a little old.
Can anyone help me with this problem... please! It is now at 30% since I typed the last few lines. I can sit and watch this thing draining like a bathtub.

try changing the usb port on the phone

I had this issue caused by water damage quite recently - it was in my pocket during some absolutely unprecedented rain here in the UK, and although it seemed I could charge it without problems, when it was off the charger it'd be confused and flash on and off as you say. I just threw it in some rice and took it out at midnight, problem solved (whether the rice was actually responsible for solving it, I have no idea). Has your phone been used in the rain or anything like that, or been in the pocket of clothes that aren't very 'rainproof' during rain? Could be it.
Is it the charger? I had a bad car charger that did the same thing. If not, I would contact Samsung and see what they can do for you.

I read about the water damage being a possible culprit but I cannot remember it getting wet anytime recently. It is not the charger, it does the same thing with two different chargers and the car charger. It does actually charge, thats not the problem. The problem is when I am away from the charger the screen just comes on all the time and the battery is drained rapidly. It has been having issues for a week or two now but just recently started having the problem when not actually plugged in.
Someone just needs to make an app with an option NOT to turn on the touchscreen when first plugged in.

Have you been able to fix your issue? I've had zero issues with my Galaxy Nexus for months, and now I'm having the same problem you describe. Initially I thought it was the ROM, but last Sunday I noticed that the phone will simply not sleep without being charged. The USB port appeared to be bent downward, so I used a tiny flat head screwdriver to raise the port. This seemed to fix the issue for a few minutes, but then the phone kept waking up. It's murdering my battery, and I'd like to fix this situation. The problem seems to be intermittent, and occasionally it will work for hours at a time. This leads me to believe that the problem could be internal.
I'm wondering if you tried anything else? I don't have a problem replacing the USB port myself because it seems like an easy and cheap fix. I'm not a novice when it comes to repairing phones, but I'd rather not open the device quite yet.
The new part is $8.00 shipped, and the seller is in the US. You can't go wrong. I will report back once I fix the problem.
Not really, the problem just sort of went away a week ago... I'm getting the Galaxy S3 end of October so I'm not going to replace the USB port. I messed around with the usb thing too, bent it with a knife so it wasnt touching anything. I also tried cleaning the contacts and blowing it out with air... not sure if any of these things helped or not. Like I said if I made it worse didnt matter as I'm getting GS3 soon. So for now its working but not sure why or how or how long...

I've got the exact same issues, it's ruining my battery life. Has anyone found a fix for this yet?
Its a physical problem. You need to replace the charging port, or get new phone like me.

@calaski8123 -> how would I replace the charging port? Should I contact samsung/google?? I have the exact same issue being discussed here and its driving me nuts. And I got this phone just a couple months ago so getting a new phone is not a solution...
best,
-Nripesh
If its new I'd take it back under warranty. If not, you can buy the parts on ebay and other sites... Search the Forums here, there are details. You can also search Youtube for a guide. Samsung probably would fix but it would cost much more.
Mine is better, but not sure what fixed it. The battery still doesn't last but half a day so I'm still getting the S3 in week or so.

Gnex Charging Issue
Hi all! Yes, I am another one of the unfortunate owners of a Gnex with this issue. I wanted to send out a reply to everyone that says to replace the USB charging port. I just had mine replaced, and it did not fix the problem. I have also tried different batteries, and I have read where some people are fixing this by *** gently *** bending the USB connector up ( toward the screen ). That also did not fix my problem. A few days ago I installed AOKP 4.2.1, and that was ineffective as well. I am stumped. My Samsung Fascinate was a very good phone, but the Gnex is really making me wonder if I ever want another Samsung. Has anyone found a solution for this? Unfortunately for me, I bought mine used and don't have the option of returning to Verizon for help. Thanks!
Hey Guys,
Over the last year or so I've had intermittent charging issues with my Galaxy Nexus. About 4 months ago is when it first started happening, the phone would either not charge or only charge when it is turned off. Somehow the issue was resolved through tons of troubleshooting, I'm not even sure what fixed it or why it started working again.
Same thing happened about 2 weeks ago, except this time it won't charge at all. Then 2 days later all of a sudden started charging again. Now it's happening again today, I have no idea what is going on or why this handset won't charge properly. The phone won't turn on with just the charger in and the battery out either.
I've tried various chargers including the OEM charger, I've tried up to 6 different chargers and 7 seperate micro-USB B cords. Nothing. I've tried a brand new battery that a friend bought for his phone before he threw it in and no results.
At this point I think it's the USB charger board, however I'm not sure why it would not work and then work again. Does anyone have any ideas or any solutions? I've read thousands of threads on this, from this forum and many others and have gone through some ridiculous troubleshooting methods.
SCH-I515 Korean Version.
Seriously, anyhelp is appreciated.
As of now, all of a sudden it will charge while it's off. But only to about 4% then it just stops charging. It will not charge while it is on at all.
Because it's getting worse and worse?
Relock bootloader, and return it in for warranty, if you can. I'm afraid there's not much help if you already checked for damage to the USB port.

hi
had the same problem until a few minutes ago.
received my usb/charging flex part today and changed it just before to post here.
took me like 20 min, really easy to do, everything works perfectly and i also took time to clean up a bit the phone inside of some dirts and change the housing i bought with the flex part.
As my screen is under protection since the beginning (4 months old), and that i recently bought a 2000mah battery, well i have to say that i have a new phone ready to handle the new year easily!
operation is easy and you will find plenty of videos on youtube showing how to change the usb flex (7€/$ , +/-) so pretty cheap.
Good luck
Why not buy an external battery charger and a spare battery?

I'd get a replacement daughterboard and switch it out yourself. It's easy dude, just like a previous poster already said. I just did it myself, took me all of 20 minutes and cost me $10. ifixit.com has a step by step direction sheet, if you have any questions feel free to contact me about it.
Try the following:
1.) Turn off your phone.
2.) Get a flat head screwdriver (small one)
3.) Push the flat connector inside the microusb port up. (It often gets bent downwards because it's so thin compared to other phones...)
4.) Boot into the bootloader
5.) Hit volume down until restart bootloader appears. Press power button.
6.) Start phone manually.

i dont know why, but this fixed it for me, for a short while. now the charging is intermittent and seems to come and go as it pleases.
Hi,
I had the same problem of ghost charging, it started with phone not charging when connected to charger and then randomly showing charging...
Now discovered it causes vbus_tuna_otg wake lock, resulting in high system usage in settings> battery and not letting phone go to deep sleep, causing battery drain.

Same Problem
I've come into the same problem with my Galaxy Nexus as well. If my phone is turned on, my phone will recognize that a charger is plugged in but the battery will not charge at all. If the phone is off and plugged in, the charging screen won't appear. I've tried multiple chargers and cords, 2 different batteries, and even replaced the micro usb and board, but the problem hasn't changed at all. I've managed to charge my batteries with an external charger but would like to get my phone back to normal working condition. Does anyone think that changing the actual motherboard itself might solve the problem?

I had this problem before, using something small and flat to push the charging connector off the housing will work for awhile. The pin in the charging port is bent down and is very thin it's easy to lift up just use a tiny bit of force to lift it up. The pin touching the housing is causing a short and that is causing your no charge while it's on and mine even went as far as draining my battery very quickly. I did research and found alot of people having this issue on the gnex. I eventually had to turn mine in for replacement, no problems since. Hopefully yours is still under warranty or you can buy the peice that is broken and replace yourself, there is a post above saying what to do for that.
Looks like my phone developed this problem. It sometimes won't charge be it via my pogo dock or USB cord. It seems to start taking a charge after I pop out the battery and then put it back in. I'm going to order another battery and see if that is the problem.
Thank yoiu!!
solved my problem!! I am in your debt
popping the battery out just worked for me too

I just did the remove battery trick as well and it worked. I just noticed my battery not charging yesterday but figured it was because I was trying to use a different charging in my dad's car. got to work where i left my normal charger and no luck.

That's good, I tried it a few times but the issue still pops up. To be fair though, I've had this phone and battery since launch day... Almost three years old. I ordered a new battery so hopefully I won't have the issue anymore... And I won't be surprised if my battery life is a little better too.

The Galaxy Nexus is nowhere near three years old. Your phone would be 18 months old if you had it since launch.

Excuse me, two years. According to Samsung their lithium batteries have a life of about 500 cycles. So my point is still valid, my battery is probably just on it's way out. I'll find out for sure when my new one comes tomorrow.

Yeah, since battery life hasn't exactly been the strong point of the GN and some of us had to go though a complete cycle daily, I suspect a lot of folks are going to be seeing more and more issues. Not too long ago, I had a battery that failed in such a way that it would randomly crash the phone and had to be pulled in order to allow a reboot. I would've suspected anything but the battery in that case.

This kind of worked for me, but the "boot into bootloader and restart it" killed my phone, don't know why. After a lot of a hassle i got it on, with 2% left, again not charging...tried to repush the connector towards the center and now i cant get my charger into the phone, maybe overbend it...what to do?...
I have a strange problem, my Gnex does not charge the battery, first i thought that it was the battery so, I tested the battery on other phone and it charged just fine, and then i ordered the usb/charging assemble from ebay and replaced on my gnex, and still not charging the battery, but when i connect the phone to the pc it recognize it immediately, but still won't charge the battery, anybody has an idea of what my problem is?? and how can i solve it?
Please help!!!
Okay, gonna try and explain this as best I can, bear with me.
2.5 years ago or something I got a Gnex from Verizon, brand new. The phone would act like a ghost was using it, like someone was interacting with the touchscreen. It'd randomly call contacts, send texts (random letters/numbers), all kinds of weird stuff. Video of it on day 1 HERE doing this. Took it into Verizon, got a new replacement. Never had the problem again. 2 or so years go by, not a single problem, unlocked, flash, all that, never had the problem again.
About a month ago, I upgraded to a Moto X and passed this phone on to a family member. At the time was running the latest stable Cyanogenmod ROM, the last for JB. 10.2 maybe? Anyway, that's what ROM was on it, again, no problems. Factory reset the phone to wipe my stuff, left it rooted and unlocked. I gave them the phone, battery, extended battery, and a few cases as well, no charger cause I know they'd twist up and destroy the factory cable. Setting the phone up for them battery starts going low, used their charger. Cable had shorts and crap, scavenged around looking for good charger. Get phone set up for them, and I'm done, handed off.
A day later, they're complaining that the phone is going crazy, like a ghost is using it, and it's randomly calling people, sending texts, opening menus, not charging, etc. Sounds like EXACT same issue I had with my very first Gnex that I exchanged. Figured that was really strange, maybe it was the software. Factory reset to latest factory image 4.2.2, lock BL back up, completely bone stock. Re-setup phone and all that jazz. Phone's acting fine. Decided this time that'd I'd let them have the original stock charger, thinking maybe that'd help with the charging issues too. All seems well....
However, during the reset and all, and after re-setting up the phone, battery is low.... plug it in with a known good charger of mine, but not stock original, and all the sudden the phone's freaking out again. Turn screen off, turns itself back on. Dialing people, opening apps on its own, etc. Figure maybe this Gnex just won't take any charger except it's original. Pull battery, reboot, phone's fine, fine for 10+ minutes. Plug in OEM charger this time, wait a few seconds, unplug, phone goes crazy.
Also interesting, they brought another charger of theirs with a little red LED on, plug it into wall, red LED comes on. Interestingly, if the charger is unplugged from wall with red LED off and I plug it into the phone.... the red LED on the wall charger turns on... that's not right. So.... here's where I'm at now. If I pull battery, reboot, and never attach a charger, the phone acts perfectly fine. The instant I plug in ANY charger, it'll start going wacko and continue to until I pull battery and reboot. At first I thought this was a charger issue, but now... I'm thinking it's battery related. This little experiment of getting the phone to go crazy after plugging in a charger applies to both the OEM and extended battery, regardless of what charger I use.
When I owned the phone, I almost exclusively used the OEM charger, occasionally another charger I had that I know works fine. Gave Gnex to family member WITHOUT a charger, so they were forced to use who know what condition phone charger. I'm wondering if maybe some rogue jacked up phone charger with shorts in it and crap somehow killed the extended battery. Then, they switched to the OEM battery, and again, unknowingly killed that battery too with the same crap charger. So maybe buying a new battery would fix the issue and only using the OEM charger from now on or the other one that was mine that I know works? Or maybe the phone is just broken now? It just doesn't seem right that plugging a phone into the micro-USB should turn ON the red LED on the charger when it's not plugged into the wall, like the power is coming out of phone and going into the LED...
I just refuse to believe that on the exact same day and within hours of me upgrading to a Moto X and passing on my Gnex that had worked perfectly for 2 years in my possession somehow just happens to "break" or "go bad" on its own. Thought it was software glitch/bug in CM, no. Thought it was incompatible charger, no. Maybe the batteries are bad? Maybe the phone's circuitry got jacked up too? Just seems weird that, as far as I can tell, pulling the battery and rebooting fixes it for good until the battery dies. Within 30 seconds of connecting a charger, the phone goes bonkers.
Any ideas? Feel bad, family member probably thinks I dumped a bad phone on them!
Thanks!
What kind of sorcery was that? I honestly don't know what to say about this other than bad timing? I highly doubt a ghost is possessing the phone.
I know a ghost isn't possessing the phone, I just, that's how I best described it when it was going wacko by itself. Plus, interesting topic title, maybe get a few more people to read it and maybe offer some advice or info or something :laugh:
However, I do have a ghost in my house, or a spirit or something. I've seen him, sitting on my couch before. He died in a fire, smoke inhalation, no smoke alarms in the house. House was sold, completely rebuilt, and I am first to live in it since then. Crazy story for a different forum lol
From what I can see, it's just that the screen isn't working properly because of leaked currents from the battery or the charger... Just get the whole screen replaced (it's hard to only replace the glass layer) and should be fine.

Leaking currents, had it happen to me before from a bad charger. I doubt it's the battery, try an outlet in a different house, they may have bad power.
Sent from my Galaxy Nexus using Tapatalk
So this "leaking currents" problem, it's a problem with the battery? A problem with the phone, in particular, the screen? It definitely sounds like a rogue bad charger could have done this based on the feedback so far. The "damage" or whatever happened at their house. Just the other night, they brought the chargers and phone and stuff to my house, a different house, problem persisted. So I'm not thinking it's a dirty power issue or anything.
...and so you should have the screen replaced. I've had Motorola and HTC phones with issues responding to touches when charging, and replacing the screen largely eased the problem (although I still ended up getting a new charger because I don't want it to also damage the newly replaced screen).

Could be the battery, could be the USB cables or chargers, could be the USB port on the device, could be the screen. The fact that it only happens when plugged in but with more than one charger and battery makes me suspect the USB port on the device. From my understanding you can buy a replacement. A temporary fix would be to use a charger that charges the battery outside of the phone.

No ghost... i think
I think its because the charger you use....
I had the same problem, but not with gnx... before gnx I used galaxy i5801...
when I put my mobile in charge, my mobile did some crazy things, like operating itself,...I figured out that the charger I used is not the one I shouldn't use.
every mobile has a charging limits, like voltage restriction..
little difference in voltage could make big difference.
so I changed the charger. problem solved for me.
other than charger.. there are some things can do this, I don't know about all.
I doubt it may caused by your digitizer...maybe is has too much sensitivity, caused by water, dust, pressure, etc....
digitizer and display are not the same.
I faced this one too ( galaxy i5801) before charging problem, but not with gnx.
A digitizer is the part of a touch screen that senses your touch and "digitizes" your gestures into impulses that the phone can understand as commands.
if it continues my last suggestion.... call the priest
Well, I borrowed an OEM standard and extended battery from a friend, neither fixed the problem. My friend did say that similar to my first Gnex, when he first got his, it did the same exact thing, but after a while it stopped and it hasn't done it ever since. I also narrowed it down, or, widened the issue, in that it's not just AC chargers, the exact same stuff happens with a brand new 12V car charger.
Dirty power on the fifth rail of a USB wire. Its either the charger not supplying enough power or a damaged cable.

My vote is on the screen, due to the digitiser. Replacing the touchscreen could help solve the problem. I was in your family's position when I got a used Motorola Cliq from a friend and the battery was all good, no leaks. Ghosts just started touching it everywhere like a crazed groupie when it went into my possession. No explanation as to why it happened and I didn't look into it that much but replacing the screen is the most likely solution.
So I woke up this morning to find my Tab drained. I plugged it in for half an hour, then when I picked it up I noticed there was no charging indicator (the green liquid battery thing). So I thought maybe I didn't plug it in right. I reattached everything, tested the charger on another device, then plugged it back into the tab for about 2 hours...still no juice. I tried powering on and doing the reset thing. still nothing. I brought it to a Samsung service center and they said I have a faulty motherboard. Now I'm wondering how the hell that happened when I've been using this device for about 6 months (only 6 months) without any issues, no overheating or strange reboots or anything, and now just like that I have a motherboard issue? The kicker here is that they're charging 75% of the tablet price to fix it! What gives?! I purchased it from a non-samsung mall store so they said I can't claim warranty. I popped the back off and did the battery pull thing and tried to charge - still nothing. Did I buy a device that decided it was a lemon after 6 months light-moderate use?
Anyone else have this happen? It's never been dropped or anything and I was on stock firmware with nothing but root.
In the UK, If your tablet goes faulty in 12months your guarantee is with the place you bought it from, not Samsung.
John.
It's ALIVE! I thought I'd get a 2nd opinion on my Tab since the guys at the Samsung service center popped it open anyway. Went to a generic phone repair store, all they did was hook it up to this box thing, and it came back to life! The guy said something got corrupted and just re flashed everything to stock rooted. He charged me less than $20 and I have a working Tab again. Obviously the very first thing I did with my resurrected device was to call Samsung's hotline and report how this one service center was trying to scam me into buying a motherboard that cost nearly as much as what I paid for the thing brand new.
Some li-poly battery have an protection circuit built in, if the voltage falls below a certain level say 2.5volts per cell, it disables the battery, if you connect an meter to the battery you will get 0volts , you need an li-ion charger that passes an higher voltage that resets the battery and allows it to work again, I wonder if this is what happened.

Did they connect via USB or to the motherboard?
@tinderbox could be...must have over-drained itself for some reason.
@ashyx I couldn't really see what he was doing since his work table was obstructed by a bunch of stuff and he had his back towards me, I just saw him grab this small black box, then minutes later he showed me that the tab was already powering on though couldn't get past samsung logo, then he went ahead and flashed to stock.
Reason I ask is I wonder if he used a jtag box to ressurect it by reflashing the bootloader.
If he did there must be jtag points on the board as it can't usually be done via USB.
Pity you didn't ask what he actually did as I'm intrigued now.
Did the box look like this: riff box

Exactly the same or just similar?
yeah i think so... it had similar ports, though not sure about the outer shell of it... i think it was smooth all around with no ridges or anything, just a little black rectangular box.
Sorry to revive an old topic, but i thought i'd do an update instead of start a new one. Tab S died again and I'm now convinced it's over-discharge, as I left it at about 20% and forgot to plug it in before going to bed. Woke up with the tab drained, not responding to any button combinations, not charging with any of my chargers that tested ok with other devices.
Instead of bringing it back to the technician, I thought I'd try mcguyvering the damn thing. I opened up the back, pried the battery terminals up off the board, lifted the battery out, and with a spliced USB cord hooked up to a powerbank, I gave the battery terminals a direct zap, inserting the exposed USB wires into the battery terminals. This took some trial and error as, I didn't know which wire was supposed to go where, but finally I saw the powerbank leds blink, indicating it was discharging into something. I held the wires in place for about 5-10 minutes, noticing some heat on the battery by then. I reinstalled the battery back into the tablet, closed everything up and tried charging again and...hey presto! the tab started charging. :victory: Let it charge for 2 hours and powered on like nothing happened.

I don't recommend you defibrillate your device's battery unless you know exactly what you're doing and are fully aware of the risks. (I didn't know what I was doing at the time but I was so frustrated at that point I didn't mind if the battery blew up in my face.)
Mine just dead last night while CHARGING (turned off at 13%).....
And refused to turn on till now (still charging and both warm (charger + tab)...
I even plugged an ampere meter to really know if its drawing any or not (it is, at 5.2V 1.7A for 15mins)...
And still no luck
Samsung's device become more ****ty each generations..... Esp the battery...
This one is the replacement batt they gave me after 2mos of usage for infamous Tab S battery issue...
I saw a video on youtube, a guy had a dead 10.5" T1 he took the back off and connected an 1amp microusb charger pcb to connections directly to the battery under a piece a tape, I bought a couple of the microusb charger pcb`s from ebay for 0.42p each in case mine goes dead.
EDIT: I found the video.

Samsung tablets only have issue with battery connectors. The white connector with 6 wires has loose connection, the black connector soldered to mainboard has cracked solder joints. New battery won't solve problem if you don't fix these two flaws. Resolder the battery connector will fix most of problems: not charging, reboot, flickering, auto shutdown.
I posted more details in the threat: flickering screen.
so the problem is Samdung's QC....
anyway no more somedung, I switched to Xiaomi Mi Mix, still preordering from China.....
You have to watch these chinies owened tablet and phone manufactues, they have been found to come with built in spyware, sending copys of all your texts ect back to china, it`s been in the news that last few day`s
Lenovo notebooks had a spyware app and Lenovo had to issue insturctions on hot to remove it once it was found.

That's OK, I can scan and remove all those spyware.
Still its better to have it properly supported with actual updates (older phone still got all UI + android update, hello MIUI 8).
Rather than using phone without proper software support....
Tab S - buggy and prolly the last MM update
Note 3 - useless LL update, very unstable, consider alpha
Note 8.0 - buggy last KK update, switched to CM13 and happy with it
